A story about how a busy programmer became responsible for training interns.

So I was put in charge of a team of interns and had to teach them to work with Linux, coding (Bash, Python and JS) and networking overall.
None of the interns had any technical experience, skills, knowledge or talent.
Furthermore the task came to me as a surprise and I didn't have any training plan nor the time.

Case 0:
Intern is asked to connect to a VM, see which interfaces there are and bring up the one that's down (eth1). He shuts eth0 down and is immediately disconnected from the machine, being unable to connect remotely.

Case 1:
Intern researches Bash scripting via a weird android app and after a hour or so creates and runs this function: test(){test|test&}
He fork-bombed the VM all other interns used.

Case 2:
All interns used the same VM despite the fact that I created one for each.
They saved the same ssh address in Putty while giving it different names.

Case 3:
After explicitly explaining and demonstrating to the interns how to connect to their own VMs they all connect to the same machine and attempt to create file systems, map them and etc. One intern keeps running "shutdown -r" in order to test the delay flag, which he never even included.

Case 4:
All of the interns still somehow connect to the same VM despite me manually configuring their Putty "favorites". Apparently they copy-paste a dns that one of them sent to the entire team via mail. He also learned about the wall command and keeps scaring his team members with fake warnings. A female intern actually asked me "how does the screen knows what I look like?!". This after she got a wall message telling her to eat less because she gained weight.

Case 5:
The most motivated intern ran "rm -rf" from his /etc directory.
P.S. All other interns got disconnected because they still keep using his VM.

Case 6:
While giving them a presentation about cryptography and explaining how SSH (that they've been using for the past two weeks) works an intern asked "So is this like Gmail?".
I gave him the benefit of the doubt and asked if he meant the authorization process. He replied with a stupid smile "No! I mean that it can send things!".

FML. I have a huge project to finish and have to babysit these art majors who decided to earn "ezy cash many" in hightech.

Adventures will be continued.

API Guy.

He has a serious regex problem.
Regexes are never easy to read, but the ones he uses just take the cake. They're either blatantly wrong, or totally over-engineered garbage that somehow still lacks basic functionality. I think "garbage" here is a little too nice, since you can tell what garbage actually is/was without studying it for five minutes.

In lieu of an actual rant (mostly because I'm overworked), I'll just leave a few samples here. I recommend readying some bleach before you continue reading.

Not a valid url name regex:
VALID_URL_NAME_REGEX = /\A[\w\-]+\Z/

Semi-decent email regex: (by far the best of the four)
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

Over-engineered mess that only works for (most) US numbers:
VALID_PHONE_REGEX = /1?\s*\W?\s*([2-9][0-8][0-9])\s*\W?\s*([2-9][0-9]{2})\s*\W?\s*([0-9]{4})(\se?x?t?(\d*))?/

and for the grand finale:

ZIP_CODE_REGEX = /(^\d{5}(-\d{4})?$)|(^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$)|GIR[ ]?0AA|((AB|AL|B|BA|BB|BD|BH|BL|BN|BR|BS|BT|CA|CB|CF|CH|CM|CO|CR|CT|CV|CW|DA|DD|DE|DG|DH|DL|DN|DT|DY|E|EC|EH|EN|EX|FK|FY|G|GL|GY|GU|HA|HD|HG|HP|HR|HS|HU|HX|IG|IM|IP|IV|JE|KA|KT|KW|KY|L|LA|LD|LE|LL|LN|LS|LU|M|ME|MK|ML|N|NE|NG|NN|NP|NR|NW|OL|OX|PA|PE|PH|PL|PO|PR|RG|RH|RM|S|SA|SE|SG|SK|SL|SM|SN|SO|SP|SR|SS|ST|SW|SY|TA|TD|TF|TN|TQ|TR|TS|TW|UB|W|WA|WC|WD|WF|WN|WR|WS|WV|YO|ZE)(\d[\dA-Z]?[ ]?\d[ABD-HJLN-UW-Z]{2}))|BFPO[ ]?\d{1,4}/

^ which, by the way, doesn't match e.g. Australian zip codes. That cost us quite a few sales. And yes, that is 512 characters long.

WTF Python!!! "Master" and "Slave" perfectly convey the concept. In the English language many words have different meanings based on their context. It's plainly obvious that no allusion to human slavery is meant in the context of software or hardware module relationships. I don't even think it is problematic. The real problem seems to be the people who are taking terms outside their intended space. Why are we linking a scar on human history to terminologies explaining technical relationships?

Then lets also ban 0 and 1 because it can offends non-binary peoples!

This facts are killing me

"During his own Google interview, Jeff Dean was asked the implications if P=NP were true. He said, "P = 0 or N = 1." Then, before the interviewer had even finished laughing, Jeff examined Google’s public certificate and wrote the private key on the whiteboard."

Currently on an internship, PHP mostly, little bit of Python and the usual web stuff, and I just had the BEST FUCKING DAY EVER.

Wake up and find out I'm out of coffee, oh boy here we go.

Bus leaves 10 minutes late, great gonna miss my train.

Trains just don't wanna ride today, back in a bus I go, what's normally a 10 minute train travel is now a 90 minute bus ride.

Arrive at internship, coffee machine is broke, non problem, I'll just lose it slowly.

NOW HERE COMES THE FUCKING GOOD PART!!

Alright, so I'm working on a CMS that can be used just about on any device you want, mobile or desktop, it's huge, billion's of rows of scientific data. Very specific requirements and low error margins. Now, yesterday I was really enjoying myself here until today, Project manager walks in, comes to my desk and hands me a Samsung Gear S3, an Apple watch and some cheap knockoff. He tells me that before the Friday deploy, THE ENTIRE CMS SHOULD WORK ON THOSE WATCHES!

I mean, don't get me wrong, I like a challenge but it's just not right, I mean, I'm still not sure what the right way to handle tables on phones is, but smart watches, just no. Besides that, I've never worked with any Apple devices, let alone WatchOs, nor have I worked with Android Wear.

Also, Project Manager is a total dickhead, he's the kinda guy that prefers a light theme, doesn't clean up his code, writes 0 documentation for an API, 1 space = tab, pure horror.

So after almost flipping my desk, I just called my school coach to announce I'm leaving this internship. After a brief explanation he decides to come over, and guess what, according to the Project Manager I wasn't supposed to do that, I was supposed to test if it would be possible.

FUCKING ASSFUCKFACE

I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.

(tl;dr at the bottom.)

I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.

For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.

tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.

There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.

And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.

The only reason this exists is because fucking power-hungry doucherockets exist.

Step 0: Feel incompetent with coding skills
Step 1: Try to practice by writing programs or learning new software, etc...
Step 2: Lose motivation and watch Netflix
Step 3: repeat

I'm a new developer. Here is the top advice I've received:

0. Think like a programmer, outside of work too.

1. Programming is tough. It takes a certain kind of mindset to sit in front of a monitor and think it through a problem till the end. Develop that mindset.

2. Handwork pays.

3. Do it for fun. Be exceptional. Money will follow.

4. Care about the craft you build. Write such a beautiful code that your fellow devs would think about your code and have a nerdgasm.

5. Simple is beautiful. Anybody can make things complex. It takes a stroke of genius to make things simple.

6. Write modular code. It makes your code reusable and easy to maintain. Future developers who will work on your piece of code will appreciate it.

7. Share your knowledge. Unlike materialistic things, knowledge grows when you share it.

8. Add comments. You think you'll remember why you wrote that piece of code that way or a clever hack you created but trust me, you won't.

9. Be humble. You'll never know everything. Don't hesitate to ask for help.

10. Writing code is exciting! Of course there will be some frustrating moments. But don't give up! You'll miss a lot of fun.

I've had my share of incompetent coworkers. In order of appearance:

1. A full stack dev. This one guy never, and I mean NEVER uses relationships in their tables. No indexing, no keys, nada. Couple of months later he was baffled why his page took ten seconds to load.

2. The same dev as (1). Requirement was to create some sort of "theme" feature for a web app. Hacked it by putting !important all over the place.

3. The same dev again. He creates several functions that if the data exists returns a view, and if it doesn't, "echo '0'". No, not return 0 or return false or anything, but fucking echo. This was PHP. If posted a rant about this a few months ago.

4. Same dev, has no idea what clean code is. No, not just reusable functions, he doesn't even get indenting right. Some functions have 4 spaces, some 2 tabs, some 6 tabs! And this is inside the same function. God wait until he tries Python...

5. Same dev now suggests that he become the PM. GM approves (very small company). Assigns me to travel to a client since they needed "technical assistance about the API". Was actually there to lead a UAT session.

Intermezzo, that guy went from fullstack dev to PM to sales (yes, one who calls clients to offer products) to business development, to product analyst in the span of two years.

After a year and a half there, I quit.

6. New company, a "QA engineer" who also assumes the role as the product owner. Does absolutely no tests other than "functional tests" in which he NEVER produces any form of documentation. Not even a set of test cases. He goes by "intuition".

7. Same guy as (6), hands me requirements for a feature. By "hands me" I mean he did that verbally. No spec documents, no slack chat, no Trello card. I ended up writing it as a card in Trello. Fast forward to the due date, he flips out because that wasn't what he wanted. Showed him the card. He walked away, without thinking of a solution how this mess should be handled.

Despite all this, I really don't want him (6&7) to leave the company. The devs get really stressed out at this job and he does make a really good person to laugh with/at.

Great news, our company's has a brand new security-first product, with an easy to use API and a beautiful web interface.

It is SQL-injection-enabled, XSS-compatible, logins are optional (if you do not provide a password, you are logged in as admin).

The json-api has custom-date formats, bools are any of "1", "0", 1, 0, false or null (but never true). Numbers are strings or numbers. Utf-8 is not supported. Most of our customers use special characters.

The web interface is using plain bootstrap, and because of XSS it is really easy to customize everything.

How the hell this product got launched is beyond me.

1 or 0

Stupid bloody PM.

I asked him for two images a long time ago: a 1x and a 2x ‘0’ monogram for Apple wallets, since we currently have monograms for glyphs 1-9 and a-z. And this is in production, so any merchant whose name starts with a ‘0’ will cause a crash. We’ve been fortunate thus far.

But this PM. He lied about who needed to make the images for three weeks, saying it’s up to the designer, when he actually made them himself. He also said he was going to take care of handing the task off, and never did, and then said designer when on FTO. When I asked the designer about it after he came back, he had no clue what graphics (and even the feature) I was talking about, or even what the requirements for the graphics might be. I had to confront the PM before he admitted he made the originals, and (begrudgingly) said he would make the new ones.

When said PM did finally make the images, the colors were all wrong. They’re not the light teal from our branding, they’re dark blue and the font is different, making them pretty ugly.

Also, after assuring me that the naming convention for the new images is the same, I discover that they’re neither organized into folders nor even named properly. (And yes, he is aware of how it should be.) I can rename and move them around easily enough, but come on, don’t say you did the work and then give me a mess to clean up!

And to top it all off, he completely spaced making the ‘u’ monograms, so I’m still short a fucking glyph!

Asdfjskldf.

How do you do every single thing wrong? Like, how!?

I had to open the desktop app to write this because I could never write a rant this long on the app.

This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.

Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.

[START RANT]

"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."

From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table

The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.

The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:

array[index]

Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.

Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:

a = {1, 5, 9};
a["hello_world"] = "whatever";

a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.

This is the difference between indexing and lookups. But you may say,

"Algo! If I do this:

a = {"first", "second", "third"};
print(a[1]);

...then "first" appears in my console!"

Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:

Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):

el = arr + (sz * i)

This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.

That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.

How my keyboard evolves:

0. Like any normal man, I started with a cheap standard Qwerty keyboard. As I began learning programming, I wanted something more elegant, so...

1. I've been using layout Dvorak (and then Programmer Dvorak) for like 5 years+ now. Anyone has intention to type on my machine soon gives up or even is blocked by me from the very start. It always takes a couple of minutes to explain to them what's going on here. They think I'm weird. I feel untouchable :)

2. My first mechkey was a 104-key Filco. Time flew by and I wanted my thing to be more compact so I went for a 66% and a TKL.

3. Recently I find out that though my keyboard is not a full-sized, there're yet some keys I've never touched (the bottom right modifiers, scroll lock, etc), so I look for a leaner one: HHKB and its alike but with slight remappings. Now I'm satisfied with the tiny, corners-trimmed keyboard but others look at it and ask how it is even possible to scroll the web page using the thing.

Prob 1: my boss can never type on my keyboard. Sometimes he still grumbles when he cannot correct my fouls right on my machine.

Prob 2: my keyboards at home and at work are not the same and some keymapping cannot applied to one of the two. That's async.

POSTMORTEM

"4096 bit ~ 96 hours is what he said.

IDK why, but when he took the challenge, he posted that it'd take 36 hours"

As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"

I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths

@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.

Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.

What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.

This started cropping up, ironically, right after I posted the thread, whats a man to do?

So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.

Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.

For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.

So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)

x = a/p
y = b/p

1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.

2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.

3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.

Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.

Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.

Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.

I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.

The final result in executable pseudo code (python lol) looks something like the above variables plus

while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i

Still working but if anyone sees obvious problems I'd LOVE to hear about it.

Here are the reasons why I don't like IPv6.

Now I'll be honest, I hate IPv6 with all my heart. So I'm not supporting it until inevitably it becomes the de facto standard of the internet. In home networks on the other hand.. huehue...

The main reason why I hate it is because it looks in every way overengineered. Or rather, poorly engineered. IPv4 has 32 bits worth, which translates to about 4 billion addresses. IPv6 on the other hand has 128 bits worth of addresses.. which translates to.. some obscenely huge number that I don't even want to start translating.

That's the problem. It's too big. Anyone who's worked on the internet for any amount of time knows that the internet on this planet will likely not exceed an amount of machines equal to about 1 or 2 extra bits (8.5B and 17.1B respectively). Now of course 33 or 34 bits in total is unwieldy, it doesn't go well with electronics. From 32 you essentially have to go up to 64 straight away. That's why 64-bit processors are.. well, 64 bits. The memory grew larger than the 4GB that a 32-bit processor could support, so that's what happened.

The internet could've grown that way too. Heck it probably could've become 64 bits in total of which 34 are assigned to the internet and the remaining bits are for whatever purposes large IP consumers would like to use the remainder for.

Whoever designed IPv6 however.. nope! Let's give everyone a /64 range, and give them quite literally an IP pool far, FAR larger than the entire current internet. What's the fucking point!?

The IPv6 standard is far larger than it should've been. It should've been 64 bits instead of 128, and it should've been separated differently. What were they thinking? A bazillion colonized planets' internetworks that would join the main internet as well? Yeah that's clearly something that the internet will develop into. The internet which is effectively just a big network that everyone leases and controls a little bit of. Just like a home network but scaled up. Imagine or even just look at the engineering challenges that interplanetary communications present. That is not going to be feasible for connecting multiple planets' internets. You can engineer however you want but you can't engineer around the hard limit of light speed. Besides, are our satellites internet-connected? Well yes but try using one. And those whizz only a couple of km above sea level. The latency involved makes it barely usable. Imagine communicating to the ISS, the moon or Mars. That is not going to happen at an internet scale. Not even close. And those are only the closest celestial objects out there.

So why was IPv6 engineered with hundreds of years of development and likely at least a stage 4 civilization in mind? No idea. Future-proofing or poor engineering? I honestly don't know. But as a stage 0 or maybe stage 1 person, I don't think that I or civilization for that matter is ready for a 128-bit internet. And we aren't even close to needing so many bits.

Going back to 64-bit processors and memory. We've passed 32 bit address width about a decade ago. But even now, we're only at about twice that size on average. We're not even close to saturating 64-bit address width, and that will likely take at least a few hundred years as well. I'd say that's more than sufficient. The internet should've really become a 64-bit internet too.

!rant & story_time
This happend to the startup I was working for at ~2011. I was a junior Android dev, working on a very popular app.
During experiments for a new feature, I discovered that the system AlarmManager has a serious bug - you can set a repeating alarm with interval=0ms. If your app takes more then 1 ms to handle the Intent, then the AlarmManager will start to fill up the intent Queue, with unexpected results to the OS. causing it to slow down, and reboot when it ran out of Ram. Why? my guess was that because the AlarmManager was part of the OS, then any issues caused by it caused the system process to ran out of ram, crashing it, and the whole system with it. the real kicker was that even after a reboot, the AlarmManager still had Intents queued, causing the device to bootloop for a while, untill the queue was cleared. My boss decided to report the problem to google, as this was an issue in the OS. I built an example app, that caused the crash 10-30 seconds after starting, and submitted to Google. Google responded later that day with "not an issue, no one will ever do this".
Well... At this point I decided to review the autoupdate feature in our app, to make sure this will not happen to us. We just released a new feature where a user can set an update schedule option in the app settings - where you could setup a daily, weekly, or hourly update for the app. after reviewing it, It looked good, and the issue was not triggered in the manual QA I did. So, it was all good. And we released an updated version to the store.
After we did an update-install, we discoverd that, there was a provlem reading the previous version SharedPrefs value for the update schdule settings, and the value defaulted to 0...
the result was, our app caused all our users to go into a bootloop, and because the alarm was reset when the devices booted up, the bootloop could only be solved in a factory reset, or removing our app, before the device rebooted, and then waiting a few reboot cycles.
We lost 50 places in the market, and it took us 6 months to get back to where we were.

It was not my fault, but it sucked big time!

So I once had a job as a C# developer at a company that rewrote its legacy software in .Net after years of running VB3 code - the project had originally started in 1994 and ran on Windows 3.11.

As one of the only two guys in the team that actually knew VB I was eventually put in charge of bug for bug compatibility. Since our software did some financial estimations that were impossible to do without it (because they were not well defined), our clients didn't much care if the results were slightly wrong, as long as they were exactly compatible with the previous version - compatibility proved the results were correct.

This job mostly consisted of finding rounding errors caused by the old VB3 code, but that's not what I'm here to talk about today.

One day, after dealing with many smaller functions, I felt I was ready to finally tackle the most complicated function in our code. This was a beast of a function, called Calc, which was called from everywhere in the code, did a whole bunch of calculations, and returned a single number. It consisted of 500 or so lines of spaghetti.

This function had a very peculiar structure:

Function Calc(...)
...
If SomeVariable Then
...
If Not SomeVariable Then
...
(the most important bit of calculation happened here)
...
End If
...
End If
...
End Function

But for some reason it actually worked. For days I tried to find out what's going on, where the SomeVariable was being changed or how the nesting indentation was actually wrong and didn't match the source, but to no avail. Eventually, though, after many days, I did find the answer.

SomeVariable = 1

Somehow, the makers of VB3 though it would be a good idea for Not X to be calculated as (-1 - X). So if a variable was not a boolean (-1 for True, 0 for False), both X and Not X could be truthy, non-zero values.

And kids these days complain about JavaScript's handling of ==...

The three indicators you have spent to much time on devRant while being on the toilet:

0: You reached the post from the last day.
1: Your legs fell asleep.
2: You forgor whether you have to wipe your ass or not.

During my first-ever technical interview, the interviewer asked me "Do you know the FizzBuzz problem?"
"Uhh, not really." (I was just thinking ok this problem has a name, must be some algorithm problem)
"So the problem is basically to give you the numbers 1 to 100, if the number is divisible by 3, print 'Fizz', if divisible by 5, print 'Buzz', if divisible by 3 and 5, print 'FizzBuzz'. For other numbers just print out the number itself."

After hearing the problem, I felt so many ideas popping out of my stressed brain.

I thought for a bit and said "ok, so if the digit sum of a number is a multiple of 3, then the number is divisible by 3, and if the last digit is either 0 or 5, it's divisible by 5."
Then I started to code out my solution until the interviewer said "there's an easier solution. Can you think of it?"

This stressed me out even more.

I thought for a bit and said "well, starting from 3, keep a counter that records how many iterations are done after 3. When the counter hits 3, that number would be divisible by 3 for sure. Should I try this solution?"
The interviewer said "Sure." So I started again.

However, I struggled for about another 3min until I realized this solution is a lot harder to implement. The interviewer probably saw my struggle too.

This was the point where he stepped in and asked me "Ummmm there's an easy way of solving this. Have you heard of the MODULO OPERATOR?"

In sheer embarrassment, I finished the code in 30s.

Of course, there was no further question after this, and I felt the need to seriously reevaluate my intelligence afterwards.

You guys made my whole day for the first time since I joined. (yes all of you!)

1) I had a 'fight' with a guy I'm making a startup with. Had to explain some of the story of my life, just to clarify that I'm not evil or generally unwilling to understand - regarding me, having the need to keep using practices

2) I've found that a whole niche-community of people seems to ignore the rest of the community and won't tag along. Having spent several months to be able to help, and receiving shit or absolutely nothing, for finally trying

3) Was in a bad mood the moment I woke up, because I fought with my girlfriend last night because she fails to communicate simple things and won't realise it.

Sorry for the bad punctuation, I tried and smartphones aren't a nice way to edit such things.

So my rant is basically a thank you! Not a rant.. But still, I think you people are the best for being so relatable and making me laugh, and feel like there's more of 'my kind'.

I also just fixed a bug in my app by (finally!) asking the framework maintainer what's up, and got a response which made no sense in a logical manner.. That's a rant for another day, I'll aggregate all the 0 fucks given, when I'm finally able to leave this thing behind, and give you a proper curse-filled shit stack of the nonsense I'm experiencing!

The bug would still live if I weren't so energized by devRant

EDIT: '!' != ','

Story Time:

When I first started working where I currently am, the manager at the time decided to send us off to a conference about one of the products our institution was purchasing at the time. She also thought that it would be a good way for me, the new guy, to bond with the rest of the staff.

During the presentations we found out that the people surrounding us were not exactly developers because of a couple of things:

1. Some examples were done with php and javascript for adding functionality to said product. The product gave you the opportunity to script on top of it (think of some sort of CMS, but it does not use PHP as its backend language) EVERYONE from the "class" in this particular workshop said they were developers. But at the sight of php in a group of 80 people or so, only about 7 recognized it, including myself and my team.

2. When they showed an example with Javascript, in particular jquery, one of the dudes in the workshop said (with extreme senior level confidence might I add) "yeah I never liked Javascript because you really can't connect it to any database in a website" <--- my face went 0.o and one of the actual developers doing the presentation did a Jim from the Office and looked at some out of screen camera.

3. During a conf talk, one PHD dude showed an example in the template language the CMS used (an obscure Java based template language)in which he was proudly calling out a technique he used to include one snippet of code into another one.....at that time, one of my coworkers squinted his eyes in disbelief, got close to me and said "is this man telling everyone in here that he discovered how to include a file? like, as a new thing?" me: "lol yes", him: "this is a waste of time, do the docs for this thing show how to do it or is he doing some sort of strange maneuver for something the platform does not support?" me: "let me check....nope, it is included, for some reason he made a function that takes the...name of the file he wants to include and passes it over to that call inside of the body....which as per the docs it is the include function...." him: ".....fuck, what a waste of time and money, fuck it lets spend a couple of more minutes here and then go get a drink or something"

That last part was my favorite really, the man speaking was not just any phd holder, but a comp sci phd holder. To this day my dude would walk into my office and say shit like "I DISCOVERED HOW TO INCLUDE A FILE WITH PHP!"

What I faced when having to deal with either 0 and 1 or BOOLEAN as the outcome.

FUCK LINUX

now that I have your attention, and you’re probably angry, too, please, even if you don’t read this rant, never use code.org again. now, onto the rant…

god dammit, code.org sucks. I mean, anyone who created it or associates with it should, well, be considered a terrorist. they’re bombing students futures in computer science with false, useless, bullshit information. not to mention, their sponsors like bill gates, mark zuckerburg, and other rich asses, talk in a video about some boring ass shit that is hard to understand for anyone who doesn’t program, and not to mention, they use a fucking five dollar microphone. ear rape. even if you look at a textual version of it, then read the information on it, it’s practically useless because it's so terribly explained, and also useless. ironically enough, they focus on their animations more than their actual explinations, or their students for that matter. the fact that we had to encode a picture in binary, made me about 50% dumber, give or take a 0 or 1. then, we had to do it in hex, which wasn’t really much better, although more realistic I supposed. what's really the most depressing thing about this class is its application in the real world. I've learnt nothing whatsoever that will help me in the real world, or in computer science. I suppose there's two things that may be useful (that I already knew): hex, and that TCP doesn't lose packets. that's it. those two things. five seconds worth of knowledge from the first quarter of the year. the ideas just make me want to throw up. teaching the main ideas of computer science without actually teaching it? one of the teachers (probably a good one) enrolled her students in an online programming course just so they could understand, because the explanations are just so terrible. this is the only [high school] computer science course offered by code.org, and I signed up because it's an AP computer science class (tried to get into AP Java, the day I was supposed to take the test to get into an upper level class, I was told it didn't count as a tech credit). seriously, fuck code.org. it makes you dumber. their 'app lab' environment is pointless, just like everything else. the app lab is basically where you have a set of commands and have to make a dog bark() or a storm trooper miss() [and that's hell when they haven't introduced while loops yet]. the app lab is literally code.org going out of their way to make everything that their students are learning pointless in the real world. seriously, why can't we just use a <canvas> like an ACTUAL PROGRAMMER would do if they were to make a browser game, not use an app engine so slow it would be faster to update windows and android studio each time I run an 'app' in their 'environment'. their excuse is that the skills "transfer over" to the real world. BITCH! IF I DIDN'T KNOW JAVA, AND I WANTED TO MAKE A GAME IN JAVA, I'M NOT GOING TO LEARN PYTHON, THEN "TRANSFER" THE SKILLS I LEARNT, I'M GOING TO LEARN FUCKING JAVA. AND THAT GOES FOR EVER OTHER LANGUAGE, PROJECT, ETC.

I'm begging you code.org, stop, get help.

In january 2023 i was contacted by a recruiter offering me a job position.

I DID NOT ASK FOR A JOB.

I WAS NOT LOOKING FOR A JOB.

THEY contacted ME.

Ok. So i went along with it and see how it goes. They probably wont hire me nor would i give a shit. Chatted with this recruiter for a while. She forgets to answer my message for 5 fucking days. Twice. Once because she was doing God knows what and the second time because she was on paid vacation. Fine i don't give a shit about you at all anyways.

So this recruiter chatting has been stretched out for several days. I think over a WEEK. So she forwarded me to their lead developer.

I applied to work as a full stack java spring boot backend + angular frontend engineer.

So:
- java backend
- angular frontend
- full stack
- shitload of devops
- shitload of projects i built
- worked with clients
- have CS degree, graduated
- worked a job at their rival company

What could go fucking wrong with all of these stats right?

During technical + hr interview (3 of us on google meets) they asked me what salary I'd be comfortable with.

I said $1500/month straight out.

keep in mind:
- In my country $500 or $600 is a salary for engineers per month
- You get a raise of +$150 which is around $750 after working for 1+ year
- You can earn $1000+ after you work for +2 years
- Rent here is $200-300 a month at minimun. And because of inflation its just getting worse especially with food. So this salary is not for living but for survival.

Their lead engineer gave me a WHOLE ASS FUCKING PROJECT TO BUILD and i had to code it within 10 days. Great so at least 17+ days of my fucking life to waste on these fucktards who contacted ME.

The project was about building a web app coffee shop literally what mcdonalds has when you order via those tablets. I had to build this in java spring boot and angular. I had to integrate:
- docker, devops
- barmen, baristas, orders
- people can order at the table or to go
- each barista can take 5 orders at a time
- each coffee has different types of fields and brewing time
- each barman brews each coffee different period of time
- barista cant take more than 5 orders for to go until barman finishes the previous order
- barista can take more than 5 orders but if those orders were ordered from table, and they have to be put in queue
- had to build CRUD admin functionality coffee's
- had to export them all of the postman routes
- had to design a scalable database infrastructure for all of this alone
- shitload of stuff more

And guess what. After 10 painful days I BUILT THE WHOLE THING MYSELF AND I BUILT EVERYTHING THEY ASKED FOR. IT WAS WORKING.

Submitted it. They told me they'll contact me within 7 days to schedule the final Technical interview after they review what i built. Great so another 17+7 days of my fucking time wasted.

OH and they also told me to send them THE WHOLE GITHUB REPOSITORY AND TRANSFER OWNERSHIP TO THEIR COMPANY'S OWNERSHIP. once you do this you cant have your repository back. WTF? WHY CANT YOU JUST REVIEW THE CODE FROM MY PUBLIC REPOSITORY? That was so weird but what can i fucking do argue with these dickheads?

After a week of them not answering i contacted them via email. They forgot and apologized. Smh. Then they scheduled an interview within 3 days. Great more of my time wasted.

During interview i was on a google meets with their lead engineer, 1 backend java spring boot engineer and 1 angular frontend developer. They were milking me dry for 1 whole fucking hour.

They only pointed out the flaws in what i built, which are miniscule and have not once congratulated me on the rest of the good parts. I explained them i had to rush those parts so the code may not be perfect. I had other shit to do in my life and not work for your shitty project for $0/hour for 10 days you fucking dickriders.

So they quickly ran over to theory. They asked me where is jwt token stored. Who generates it. How the backend knows to authenticate user by it. I explained.

What are solid principles. I said i cant explain what is it but i understand how it works, why its needed and how to implement it (they can clearly see in the project i just build that i applied SOLID principles everywhere) - but i do admit i dont know the theory behind it 100% clearly.

Then they asked me about observables and promises in angular. I explained them how they work and how subscribe method is used (as they can clearly see that i used it in the code). Then they asked me to explain them under the hood of how observables work. The fuck? I dont know and dont care? But i can learn it as i work there?

Etc

Final result: after dragging this for 1 fucking month for miserable $1500/month they told me: we can either hire you now but for a much lower salary which you probably wont be happy with, or you can study more these things we discussed "and know why the car leaks oil" and reapply back to us in 2-3 months!

So I’m having an argument with my gf.

Is it “Why is 6 afraid of 7?” or “Why is 10 afraid of 7?”

I fucking said that 6 has not seen the action of 7 eating 9. But 10 has, therefore he is scared.

If we were to iterate from 0 to 10, we would see that 6 hasn’t seen shit.

Let’s print out each number if we iterate through and find a consecutive 7, 8 and 9 then print out “Oh shit 7 ate 9.”

0
1
2
3
4
5
6 // Hey honey I don’t see anything here??
7
8
9
Oh shit 7 ate 9
10 // Someone call the fucking police

Thoughts?

When I see a coworker do this:

if( recValues[0] == '0' )
{
recValues[0] = '1';
}
else if( recValues[0] == '1' )
{
recValues[0] = '0';
}

I replace it with this:

recValues[0] ^= 0x1;

Note: The recValues[0] is guaranteed to contain only '0' or '1'

Am I really unlucky, or are juniors these days all lazy af and such pampered babies that need hand holding all the time?
So back when I was a junior, when I wanted to learn something new, I would ask for some pointers from my seniors, could be an article, a video or even a book. From there I would look up further knowledge, play with the idea in my machine. If I couldn't understand something, or if I needed a better explanation of something, I would go back to my senior, but it was really rare.
Then comes this modern day, I'm the senior now and I'm in charge of mentoring a bunch of kids, who would treat me like their personal chatgpt. "Hey Junior #0, this is something you may want to read to help your next ticket, let me know if you have difficulty". Next day junior #0 would come back and say "I don't understand, the article mentioned X but I don't know how to do X. Can you show me how to do X?". Bro, no one knows how to do X after being born, just google "how to do X" and it gives you the fucking answer. Why the fuck do you have to circle back to me because of this. Junior #1 would refuse to read any articles longer than 250 words, and require constant 1-1 meetings to give him personal lectures. Dude this is not a class room, grow the fuck up! Junior #3 would write the messiest code possible despite my efforts to introduce tons of resources, then complain "why I'm still junior, how do I grow". Bro maybe if you learned half of what I sent you, you would have gotten promote by now. Fucking lazy kids these days!
Oh I can't fire these juniors. Top management was very clear that "we don't have budget to hire other devs for you, it's your responsibility to train them better".

But... But what if my kids will not know if a index starts at 0 or at 1...

Yknow what the best part about Unix is? (Not Linux. Like old school Unix. AIX, HPUX, or in this specific case: Solaris)

It never needs to be updated. like ever. Even when new features are added 5 years ago to add features that GNU has had for literally decades. Updates are for the weak. Because why should I be able to type "netstat -natup" when instead you can enjoy several hours of developing the nightmare one-liner that is:

Pfiles /proc/* | awk '/^[0-9]/ {p=$0} /port/ {printf "%.4s %-30s %-8s %s\n", $1,$3,$5,p}' 2>/dev/null

Isn't that just so much more fun?!
Thanks guys. I'm going back to GNU now if you don't mind.

Ok friends let's try to compile Flownet2 with Torch. It's made by NVIDIA themselves so there won't be any problem at all with dependencies right?????? /s

Let's use Deep Learning AMI with a K80 on AWS, totally updated and ready to go super great always works with everything else.

> CUDA error
> CuDNN version mismatch
> CUDA versions overwrite
> Library paths not updated ever
> Torch 0.4.1 doesn't work so have to go back to Torch 0.4
> Flownet doesn't compile, get bunch of CUDA errors piece of shit code
> online forums have lots of questions and 0 answers
> Decide to skip straight to vid2vid
> More cuda errors
> Can't compile the fucking 2d kernel
> Through some act of God reinstalling cuda and CuDNN, manage to finally compile Flownet2
> Try running
> "Kernel image" error
> excusemewhatthefuck.jpg
> Try without a label map because fuck it the instructions and flags they gave are basically guaranteed not to work, it's fucking Nvidia amirite
> Enormous fucking CUDA error and Torch error, makes no sense, online no one agrees and 0 answers again
> Try again but this time on a clean machine
> Still no go
> Last resort, use the docker image they themselves provided of flownet
> Same fucking error
> While in the process of debugging, realize my training image set is also bound to have bad results because "directly concatenating" images together as they claim in the paper actually has horrible results, and the network doesn't accept 6 channel input no matter what, so the only way to get around this is to make 2 images (3 * 2 = 6 quick maths)
> Fix my training data, fuck Nvidia dude who gave me wrong info
> Try again
> Same fucking errors
> Doesn't give nay helpful information, just spits out a bunch of fucking memory addresses and long function names from the CUDA core
> Try reinstalling and then making a basic torch network, works perfectly fine
> FINALLY.png
> Setup vid2vid and flownet again
> SAME FUCKING ERROR

> Try to build the entire network in tensorflow
> CUDA error
> CuDNN version mismatch
> Doesn't work with TF
> HAVE TO FUCKING DOWNGEADE DRIVERS TOO
> TF doesn't support latest cuda because no one in the ML community can be bothered to support anything other than their own machine
> After setting up everything again, realize have no space left on 75gb machine
> Try torch again, hoping that the entire change will fix things

At this point I'll leave a space so you can try to guess what happened next before seeing the result.

Ready?

> SAME FUCKING ERROR

In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.

If anyone has vid2vid working or has gotten around the kernel image error for AWS K80s please throw me a lifeline, in exchange you can have my soul or what little is left of it

Oh gosh.. i can finally understand the CV and application nightmare stories... We're getting new people in, and there are quite a few interesting ones.

0) pages of randomly placed info. PAGES. I'm lost in there!!

1) no basic info whatsoever. Like, no nationality(we're recruiting internationally), no birthdate, barely his name and email. I know that the first ones are not really needed for the job, but they're still customary.

2) entry level back and/or frontend job. This guy's a phd graduate, working research with big data in a bio-something department. We're a web startup.

3) there are some listing so much unrelevant stuff, I'm not even sure if they meant to apply to us.

4) (my favourite) email subject: application, email body: empty, attached: short_application.doc ("hi, this is an application to the posted job. Best regards, Name") WAIT WHAT?

I am using this SDK and I came across a property "Orientation" of type int.

Why int? Is it an enum or something? Let's have a look into the online documentation...

"Gets or sets the orientation."
😣

Yeah, thanks. Very useful.
It's again that kind of documentation which simply restates the property name or method name. Who needs this?

So I tried to set the Orientation property to 1 to see what happens.

A runtime exception then told me that the only valid values are 0, 90, 180 and 270.

Well, this is kind of stupid but ok, I can live with that.
But ffs, put that info into the documentation, where it belongs!

Not a rant. Just some motivation for lazy fucks :)

Everything is binary. You do it or you don't. So tell me Elliot are you a 1 or are you a 0 !!

PHP arrays.

The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.

What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.

This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.

You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.

Bonus PHP trivia:

Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.

`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.

Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.

Strings can be indexed with negative integers. Arrays can't.

ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.

`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.

Tl;dr stupid password requirements

Begin quote

Password must not contain any non-alphanumeric characters.

Your Password change was not accepted. Enter your current Password correctly following the rules for New Passwords. Please try again.

Passwords must be between 8 and 12 characters in length and MUST contain each of the following:

At least 1 lower case character (a-z)
At least 1 upper case character (A-Z)
At least 1 numeric digit (0-9)

But, MUST NOT contain:

more than five repeating characters in a row (e.g. 111111356 would not be valid, but 112233445 would be valid)
spaces or other special characters

NOTE: Your new password cannot be the same as any of your 10 previous passwords.

End quote

Are you fucking kidding me? Only (26+26+10)^8 through
(26+26+10)^12 different passwords to go through? It's like the oxygen wasters that built this website give zero fucks about security.

Why? This is the site that manages money and investments. Just allow passwords up to 64 characters, allow any ascii character and just fucking encod the characters to prevent any Injunction.

Stupid HTML checkboxes! It's always annoyed me that you can't just set checked to true or false, but have to remove the property altogether to uncheck a checkbox. Better still would be if you'd only need to set the value to 1 or 0, and the checked or not would sort out automatically. Yes, there are frameworks to handle it, I know. But if checkboxes had been designed right from start, a framework or any sort of special cases would not be needed. You've got love HTML, but things like this make it ugly.

You wanna know what the fuck we did in our goddamn code.org class today, wait no, the last whole fucking week. YES OR NO QUESTIONS. I GET BINARY IS FUCKING 0'S AND 1'S. FOR GOD SAKES I KNOW BINARY. I EVEN KNOW FUCKING TERNARY. AND. YOU KNOW WHAT TEACHER ? EVERYONE ELSE COULD LEARN BINARY IN FIVE GODDAMN MINUTES. "Is code.org worthy of being kicked in the ass and tied up on a railroad when the trains coming?" Is a perfect binary question. This whole fucking class I feel like I'm in an english class for five year olds in spain. HEY TEACHER I DON'T CARE IF BILL GATES OR MARK SUCKERBURG OR BARAK OBAMA OR GODDAMN CHRIS BOSH SUPPORTS IT. ITS FOR THERE FUCKING REPUTATION. PEOPLE WITH HALF A BRAIN KNOW THESE PEOPLE DON'T GIVE A FUCK. THEY EACH HAVE HUNDREDS OF MILLIONS OR EVEN BILLIONS OF DOLLARS, BUT THEY ALL CHOSE TO USE A FIVE DOLLAR MIC JUST TO FUCK WITH US. EVERY TIME I WALK IN THAT CLASS I FEEL DEGRADED LIKE I'VE BEEN PUT BACK IN PRESCHOOL. THANK YOU TEACHER, I ALWAYS WANTED TO LEARN BINARY TO MAKE MY FUCKING SIMPLE JAVASCRIPT APP AS MY FINAL PROJECT FOR THE REST OF THE YEAR.

I've been staffed on a old ongoing project, first day.
0. Compatibility has to be guaranteed down till IE9... ppf.
1. Front end made in XHTML+JS(jQuery)... bah, ok.
2. XHTML+JS is actually generated by PHP5.4, not a line is actually statically served... beh, funny, ok.
3. PHP files are the output of an XSLT transform of a bunch of XMLs... meh, seriously? Oooook.
4. XMLs are the product of the serialisation of a truck of stateful JavaEE6 DTOs populated magically (undocumented) with data coming from a SQL DB... WTF mode!!!
5. Session logics lives within PHP-land at point 2, front end makes ajax calls here that propagates to another WS out of our control that triggers -somehow- (undocumented) our Java backend at point 4 to generate new XMLs and then reach front end again. Kill me now.

Boss: look... it's too slow for the client, it's too heavy on our servers: fix it. Ah, and we sold 85% test coverage by October. You're the man for the job. (I'm a Node.js fullstacker and right now there's not even a testing scaffold, ofc).
Me: prod is on Linux or Windows?
Boss: RHEL7.
Me: rm -rf / as root. Done.
Boss: I know I know...
Me: ...

I think time has come...

I've got a HDD, gotta look for any data left on it. I don't need a 1:1 copy of the drive to determine if any data is even there still, and i'm also strapped for space, so I threw together a little 20-line or so Python script to skip over large amounts of empty space so I only have to sift through what little it finds to see if anything's left at all. I wrote it, ran it... and it took a while. Too long. My SSD was floored and RAM was full for no reason. I double-checked my code...

device.seek(0)
device_size = len(device.read())

If you don't get it, this would've tried to load the ENTIRE DRIVE'S CONTENTS into RAM before giving the length. The drive's 128GB or so. That's not happening.

I'm a fucking idiot.

EDIT:
This is what this was for. This ain't ext4. What in the fuck...?

So I’ve been working for this company for +4 years. When I started we were 6 dev. Now we are 1. It’s just me. Thankfully I’m leaving next week to start at another company. But right now I’m kinda loosing my mind. I have a deadline tomorrow and I’m super stressed because I’m not done. I have bugs to fix, documentation to write and all that stuff. I’m pissed off because people don’t understand what I do, why it takes time, why I want to be alone at home just coding instead of sitting at the office being interrupted with stupid ass questions about html or upcoming project. I don’t give a fuck about their clients or upcoming projects. I’m only working for them 7 more days and then they have 0 dev left. Fuck them. Fuck the CEO, fucking piece of shit. Can’t wait to flip them off leaving next week.

You can always tell if someone is a programmer by asking them:

Is zero equal to zero or equal to 1?

Non devs say 0, devs say 1

Doing a full rewrite from some DIY spaghetti framework: when it can't find a search query it returns "false" with the status code 200, the same php file responsible for querying an external api is put into all sorts of named folders, so e.g. a user that is in the results page X can continue searching on the same URL, instead of doing proper url rewrites or ajax calls to the one in the root directory, html is thrown into every other php line, a DIY sort function for a numbers array that fails to sort 0 before 1 and that all is just a 10 minute review, can't wait to see the rest.

!rant, TL;DR at the bottom

Holy fuck, Yesterday, I got absolutely schooled by a literal newbie.
And I mean, NEWBIE newbie, the dude just started a Computer Science degree, and has been learning Java only for a MONTH. He has 0 prior experience with code or anything of the like, and he's somewhat of an Ars(Israel's version of a Gopnik).
So I was helping him with some stuff he didn't understand, and lo and behold his code was probably the most aesthetically pleasing and organized code I have seen in my 8 years of programming(I know 8 is not much, but It's at least above beginner level). The dude's a perfectionist, so I was like, "Okay, very impressive, but makes sense for perfectionism"(I straight up told him: "Damn, I've seen people with years of programming experience who can't learn to write this well, and you do this by default? I envy whoever's going to work with you"), and then I saw the way he writes checks(as in, methods that return a boolean) and I think I came.
The code was:
[First method in the picture]

And I know, it doesn't look as ✨ WOW✨ as I make it sound, but in my personal opinion this both looks much better and is much more readable than what I normally write:
[Second method in the picture]

and whenever there are longer or more complicated checks it makes it look like a simple puzzle that just fits in all the pieces nicely, for example in a rectangle class we had to write an 'isIn' method, this is how I wrote it:
[Third method in the picture]

His way of writing the same thing was:
[Fourth method in the picture]

Which I think is soooooo much better and readable and organized,
It's enough just looking at the short return statement to immediately understand everything that's going on.
"Oh, so it just checks if the SW(South West, i.e. Bottom Left) corner is above and to the right, and if the NE(North East, i.e. Top Right) corner is bellow and to the left"

Point of the story? Some people are just fucking awesome. And sometimes the youngest/most inexperienced people can teach you new tricks.
And to all of you dinosaurs here with like, 20+ years of experience, y'all can still learn even from us stupid ones. If 8 years can get schooled by a 1 month, 20 years can get schooled by a 1 year.
Listen to everyone everybody, never know where you might learn something new.

TL;DR: Got schooled by a local "Gopnik" who only started learning programming a month ago with 0 prior experience with his insane level of organization and readability.

Shamless rant towards the shamless Cursey dude. 😫

So whole day I have been trying to pass a variable from laravel blade view to vue2 component file. All in seperate files. I know that I have successfully passed 1 or 0 in same flow before. So I was following the same steps to pass my string variable. It kept giving me undefined. No google helped and I had been doing all kinds of stupid useless trials. All failed.

Because it is supposed to fail. 😐
I only learned it at the end of the day.

I'm hal laughting, half facepaling.

Use multiple servers they said
It's gonna balance automaticlly your load they said.

Well, they didn';t accoubnt for a MEGA badly writen API whic can block a whole server for a minute.

Or, but it's not the end !!!

So you see ? 1 at 100%, 1 at 0% ? Quick maths : Average 50%.

Autoscaling kicks in at average 40% for 2 minutes.

So it kicks in... Created a 3d server... Which is still booting !!

And some trafic redirected there.

Sooo. Users on a 100% server : Bad bad bad for them
Users on 0% server : No problems
users on a new 3d server : Wait 15 seconds, then it's like 0%.

Fun fun fun. At least I know now which fucking API does that.

So we had a class that should have 2 states 0 or 1, you think my coworker would be smart enough to represent it with a Boolean? NO!

Represent the state inside the object as an int then when using the object in a function creates a Boolean that determines the state of the object and after the function done it's job THEN call another function that takes the object and the Boolean and change the int state inside the object depending on the Boolean.

Wouldn't it have been whole lot easier to just you know..... Make the state a Boolean from the start.

When I saw this I knew I was witnessing a miracle of the human mind. God bless!

Ps: it wasn't connected to any kind of API nor server and there are never more than 2 states. It's just some local sequential code so don't assume it had a logical reason it's just a fuck up.

0: Monitors and Graphic's Cards become affordable for us poor graduates

not all "dev" related per se, but my current day to day gripes answered

Fuck jQuery. The only reason I see anyone using it legitemately is because of backwards compatibility. Almost every jq method is either native js or native css. The problem is, some devs become practically dependent on a library. By then, they are no longer js devs. They are jQuery devs. When you find yourself going to the docs of a lib before native methods 9 times out of 10 you've gone past the turning point. When you find yourself including jQuery instinctively, you're gone. StackOverflow is a great example of this:

Question - 1 up
Pure JS answer - 0 ups
jQuery answer (same length) - 2 ups and accepted

Come on man. It's 2018! We shouldn't be writing jQuery anymore. Native methods ftw!

Arduino CNC
Hey guys.
Since I mostly see frameworks to use with G-Code in Arduino CNCs I'm gonna make my own framework, where you don't need to know G-Code and the code is executed by Arduino code.
The code would include a template to define steppers steps and such.
Would include a library to work with different stepper shields.
Would this interest to anyone?

I'll provide a full example with stuff to learn for any amateur working with CNCs or that want to work with one. If you're not interested, thank you for reading, you can stop here.

Ex:
X(10);
Y(-5.5);
XY(6,7.5);
Z(-10);
This framework would only use incremental coordinates and will work for basic forms, drilling and such.

<Tutorial>
Coordinates.
Coordinates can be relative/incremental or absolute.
Lets say you have a square with 10mm, (top coordinates: (X=0,Y=0) to (X=10,Y=10).
think your drawing this square.
First line:
X0, Y0
Absolute: x10,y0
Relative: X+10
Second line:
A: x10,y10
R: Y+10
Third Line (...)
Absolute is a fixed point (coordinate)
Relative is a distance to move (not a coordinate but the distance and direction)
</Tutorial>

So, to cut a square with a TR10 (end mill with radius=5, diameter=10)

<code>
// You don't place + in positive values
// The tool always cut in the direction of the tool rotation, meaning on the left of the material.
Z(10); // Security Distance
XY(-5,0); //Compensate the diameter of the tool in radius
Z(-1); // Z=0 is the top of the block to mill, in this case. Z=0 can also be in the bottom
Y(15); //Second Point
X(15); // Third Point
Y(-15); // Forth point
X-15; // Fifth Point
(repeat)
</code>
Now we have a block with 1mm depth. If you use a while or for you can repeat the sequence for x=n passages, change the value to Z for the depth and your done.

Our project at work goes live in 3 weeks.

The code base has no automated tests, breaks very often, has never had any level of manual testing

will not be releasing with any form of enforced roles or permissions in our first release now due to no time to enforce, however there is a whole admin api where you can literally change anything in our database including roles.

We also have teams in various countries all working separately on the same solution using microservices with shared nuget packages and they aren't using them properly.

Our pull requests are so big - as much as, 75 file changes - in our fe app that I can't keep up with it and I honestly have no idea if it even works or not due to no automated tests and no time to manually test.

We have no testing team, or qa team of any sort.

Every request into the system has to hit a minimum of 3 different databases via 3 different microservices so 1 request = 4 requests with the load on the servers.

We don't use any file streams so everything is just shoved in the buffer on the server.

Most of the people working on the angular apps cba to learn angular, no one across 2 teams cba to learn git. We use git so they constantly face problems. The guy in charge has 0 experience in angular but makes me do things how he wants architecturally so half the patterns make no sense.

No one looks at the pull requests, they just click approve so they may as well push directly to master.

Unfinished work gets put in for pull request so we don't know if the app is in a release state since aall teams are working independently, but on the same code base.

I sat down and tested the app myself for an hour and found 25 fe only issues, and 5 breaking cross browser issues.

Most of our databases are not normalised. Most of our databases make no sense. 99% of our tables have no indexing since there is no expertise with free time to do it.

No one there understands css properly. Or javascript.

Our. Net core microservices all directly use ef in the controller actions so there is no shared code there.

Our customer facing fe app is not dry because no tests so it was decided it was better this way.

Management has no idea on code state, it seems team lead is lieing to them about things like having any level of tests.

Management hire devs that claim to be experts but then it turns out they have basically no knowledge of what they were hired to do, even don't know what json is or the framework or language they are hired for, but we just leave them to get on with it and again make prs too big to review.

Honestly I have no hope that this will go well now but I am morbidly curious to watch. I've never seen anything like the train wreck that we are about to get experience.

Possibly the start of a very bad adventure: I'm helping my brother-in-law set up a website for a business he'd beginning with his wife. I'll be needing to provide him a simple cms & shopping cart that he can manage. No payments as we want to just use PayPal so as to avoid having to actually manage user data & credit card information.

Wish me well....

Also advices appreciated cause otherwise, I'm gonna use a simple Drupal or WordPress site with like 1 theme and 0 plug ins.

Im forced to work with c++ on windows for a course.

0) c++ is fucking unusable without a central repo for managing dependencies. Maybe im just too used to maven but you shouldnt be downloading dll files in 2018.

1) visual studio can go suck a fat one. I got a fairly fast pc and it takes fucking forever to load anything. For comparison, eclipse with all my plugins (and i have a lot) loads in ~10 seconds, vs2017 does in 35.

2) why the fuck is there no cross platform compilation for c++? Its supposed to run on everything right? Whats so hard about porting a fucking linux compiler so i dont realixe i have .exe files when i want to work with my laptop on the bus?

3) c++17 (? Or whatevers the newest) syntax is like a deep barf on a hot summer day after eating a whole watermelon. Its fucking unreadable and autopointers simply dont work. And its not even my lack of skill this time, its the code that the other members used and it worked for half of them.

I found this on a wiki with Haskell Humor... it's interesting...

How to Shoot Your Self in the Foot With Haskell: Putting the unsafe in unsafePerformIO!

You shoot the gun, but the bullet gets trapped in the IO monad.
Couldn't match expected type 'Deer' against inferred type 'Foot'.
While compiling your program the compiler produces a type error long enough to overflow a kernel buffer, overwrite the trigger control register and shoot you in the foot.
After trying to decipher the type errors from the compiler, your head explodes.
After you've finally found a way to circumvent the type system and shoot yourself in the foot, Oleg appears out of nothing and shoots you in the foot for coming up with it before him.
You shoot the gun but nothing happens (Haskell is pure, after all).
Your foot is fine, until you try to walk on it, at which point it becomes mangled.
You have a shootFoot function which you've proven correct. QuickCheck validates it for arbitrary you-like values. It will be evaluated only when you end up at the hospital. You hope this doesn't come to pass, as it actually returns a bullet-ridden copy of yourself and you don't want to be garbage-collected.
foreign import ccall "shootparts.h shootfoot" shoot_foot :: Gun -> Programmer -> IO ()
shootSelfInFoot = unsafePerformIO . shoot . foot $ self -- Shoot self in foot 0 or more times depending on evaluation order
No instance for (Target Foot)
arising from use of `shoot' at SelfInflictedInjury.hs:1:0
Possible fix: add an instance declaration for (Target Foot)
In the expression: shoot foot
You go to shoot yourself in the foot but the bullet is in the ST monad and the gun is in the IO monad, so you can't.
You ask Haskell to shoot you in the foot but by the rules of lazy evaluation you don't need the result yet so it doesn't happen.
You decide to shoot yourself in the foot but get distracted devising a ballistics algebra and wondering if you can do the calculations in the type system.
You want to shoot yourself in the foot but realize there is no Gun datatype so use Arrows instead.
You shoot in the direction of your foot, but since you are inside the STM monad you can just retry until you figure out what to do.
You shoot yourself in the foot, but you are perfectly fine as long you just don't evaluate the foot.
You shoot yourself in the foot, but nothing happens unless you start walking.
Don't forget about memory consumption! If you don't look, the bullet causes heap overflow. If you look, the bullet causes stack overflow.
You *appear* to have deliberately shot yourself in the foot, and yet your program actually runs perfectly OK due to lazy evaluation. (So long as you remember to not look at your foot...)
You aim the gun at your foot, pull the trigger and remove the clip. When you look at your undamaged foot, the hammer clicks on an empty barrel.

Fuck everything about Microsoft Dynamics. I'm supposed to use the REST API to make a web front-end. I notice all of the data comes back codified.

null == 0.
boolean true == 100000000
boolean false == 100000001

except sometimes when

boolean false == 100000000
boolean true == 100000001

or other times

string "Yes" == 100000000
string "No" == 100000001
string "Maybe" == 100000003

Hang on. Is the system representing a 1 bit value with base 10 numbers? Did the client set this up like this? Holy crap every number corresponds to a unique record in a table somewhere. That means it only returns numeric values instead of strings and I have to figure out what the number means in the context of the table.

A "key" is user typed? So every time someone starts to make a new record it saves a new "key" without a record? So I can pull a bunch of "0" records if I pull sequentially? So basically I need to see all of the data in Dynamics to have any context at all for what is returned from the Dynamics API? Fuuuuuuuuuu

Did the weekly discussion chat start at 0 or one?

The process of making my paging MIDI player has ground to a halt IMMEDIATELY:

Format 1 MIDIs.

There are 3 MIDI types: Format 0, 1, and 2.

Format 0 is two chunks long. One track chunk and the header chunk. Can be played with literally one chunk_load() call in my player.

Format 2 is (n+1) chunks long, with n being defined in the header chunk (which makes up the +1.) Can be played with one chunk_load() call per chunk in my player.

Format 1... is (n+1) chunks long, same as Format 2, but instead of being played one chunk at a time in sequence, it requires you play all chunks

AT THE SAME FUCKING TIME.

65534 maximum chunks (first track chunk is global tempo events and has no notes), maximum notes per chunk of ((FFFFFFFFh byte max chunk data area length)/3 = 1,431,655,763d)/2 (as Note On and Note Off have to be done for every note for it to be a valid note, and each eats 3 bytes) = 715,827,881 notes (truncated from 715,827,881.5), 715,827,881 * 65534 (max number of tracks with notes) = a grand total of 46,911,064,353,454 absolute maximum notes. At 6 bytes per (valid) note, disregarding track headers and footers, that's 281,466,386,120,724 bytes of memory at absolute minimum, or 255.992 TERABYTES of note data alone.

All potentially having to be played

ALL

AT

ONCE.

This wouldn't be so bad I thought at the start... I wasn't planning on supporting them.

Except...

>= 90% of MIDIs are Format 1.

Yup. The one format seemingly deliberately built not to be paged of the three is BY FAR the most common, even in cases where Format 0 would be a better fit.

Guess this is why no other player pages out MIDIs: the files are most commonly built specifically to disallow it.

Format 1 and 2 differ in the following way: Format 1's chunks all have to hit the piano keys, so to speak, all at once. Format 2's chunks hit one-by-one, even though it can have the same staggering number of notes as Format 1. One is built for short, detailed MIDIs, one for long, sparse ones.

No one seems to be making long ones.

I started noticing something about startups here. They all think they r innovative and full of fresh ideas, but they all just copy bigger companies. My old coworker started a small web dev company and they are using php with react, the company ladder is the fucking same as anywhere else.

I noticed these as i was collecting ideas for a company (if i write that word again pls shoot me). So far we are thinking
0) no, or minimal local storage, we would have a github subscription, jira cloud, vps
1) no strict hierarchy, ultimately the ceos would make the decisions but in every meeting we would include even the interns
2) the stack would not be set in stone, java spark and vuejs are good starting points but frameworks exist to serve a purpose
3) like 2-3 days office time per week, if someone wants to work from a café, why not

Hey, been gone a hot minute from devrant, so I thought I'd say hi to Demolishun, atheist, Lensflare, Root, kobenz, score, jestdotty, figoore, cafecortado, typosaurus, and the raft of other people I've met along the way and got to know somewhat.

All of you have been really good.

And while I'm here its time for maaaaaaaaath.

So I decided to horribly mutilate the concept of bloom filters.

If you don't know what that is, you take two random numbers, m, and p, both prime, where m < p, and it generate two numbers a and b, that output a function. That function is a hash.

Normally you'd have say five to ten different hashes.

A bloom filter lets you probabilistic-ally say whether you've seen something before, with no false negatives.
It lets you do this very space efficiently, with some caveats.

Each hash function should be uniformly distributed (any value input to it is likely to be mapped to any other value).

Then you interpret these output values as bit indexes.

So Hi might output [0, 1, 0, 0, 0]
while Hj outputs [0, 0, 0, 1, 0]
and Hk outputs [1, 0, 0, 0, 0]
producing [1, 1, 0, 1, 0]

And if your bloom filter has bits set in all those places, congratulations, you've seen that number before.

It's used by big companies like google to prevent re-indexing pages they've already seen, among other things.

Well I thought, what if instead of using it as a has-been-seen-before filter, we mangled its purpose until a square peg fit in a round hole?

Not long after I went and wrote a script that 1. generates data, 2. generates a hash function to encode it. 3. finds a hash function that reverses the encoding.

And it just works. Reversible hashes.

Of course you can't use it for compression strictly, not under normal circumstances, but these aren't normal circumstances.

The first thing I tried was finding a hash function h0, that predicts each subsequent value in a list given the previous value. This doesn't work because of hash collisions by default. A value like 731 might map to 64 in one place, and a later value might map to 453, so trying to invert the output to get the original sequence out would lead to branching. It occurs to me just now we might use a checkpointing system, with lookahead to see if a branch is the correct one, but I digress, I tried some other things first.

The next problem was 1. long sequences are slow to generate. I solved this by tuning the amount of iterations of the outer and inner loop. We find h0 first, and then h1 and put all the inputs through h0 to generate an intermediate list, and then put them through h1, and see if the output of h1 matches the original input. If it does, we return h0, and h1. It turns out it can take inordinate amounts of time if h0 lands on a hash function that doesn't play well with h1, so the next step was 2. adding an error margin. It turns out something fun happens, where if you allow a sequence generated by h1 (the decoder) to match *within* an error margin, under a certain error value, it'll find potential hash functions hn such that the outputs of h1 are *always* the same distance from their parent values in the original input to h0. This becomes our salt value k.
So our hash-function generate called encoder_decoder() or 'ed' (lol two letter functions), also calculates the k value and outputs that along with the hash functions for our data.

This is all well and good but what if we want to go further? With a few tweaks, along with taking output values, converting to binary, and left-padding each value with 0s, we can then calculate shannon entropy in its most essential form.

Turns out with tens of thousands of values (and tens of thousands of bits), the output of h1 with the salt, has a higher entropy than the original input. Meaning finding an h1 and h0 hash function for your data is equivalent to compression below the known shannon limit.
By how much?

Approximately 0.15%
Of course this doesn't factor in the five numbers you need, a0, and b0 to define h0, a1, and b1 to define h1, and the salt value, so it probably works out to the same. I'd like to see what the savings are with even larger sets though.

Next I said, well what if we COULD compress our data further?

What if all we needed were the numbers to define our hash functions, a starting value, a salt, and a number to represent 'depth'?

What if we could rearrange this system so we *could* use the starting value to represent n subsequent elements of our input x?

And thats what I did.

We break the input into blocks of 15-25 items, b/c thats the fastest to work with and find hashes for.

We then follow the math, to get a block which is
H0, H1, H2, H3, depth (how many items our 1st item will reproduce), & a starting value or 1stitem in this slice of our input.

x goes into h0, giving us y. y goes into h1 -> z, z into h2 -> y, y into h3, giving us back x.

The rest is in the image.
Anyway good to see you all again.

Is it just me or is AHK a bit braindead?

1. Why invent a worse version of other scripting languages instead of just writing a library..

2. Despite it's high lvl complex syntax it can't even manage multiline things without having 'or' 'and' '||' ',' '.' in front of every line?

Look what I had to do..

options := { image : "../../Resources/OpacitySlider.png"
, from : [ 0 , 0 ]
, to : [ a_screenWidth , a_screenHeight ] }
( commas were aligned with the curly bracket )

3. #Include isn't relative to the current file but relative to the main script?!

What the actual fuck.

Worked around it with:
#Include %A_LineFile%\..\Gdip.ahk
but wtf

( Including library files from other library files )

4. probably more, I just got the thing I was working on to work so I'd rather never touch it again if I can..

5. Profit?

I had interest in studying medicine since a very young age but I started coding before I got admission. I found medicine fun because of that.

I perceive hormones and receptors as events and event listeners.

I perceive the all or non responses of neurons as binaries 0 and 1.

I perceive the vestibular apparatus in the ear as a gyroscope and accelerometer.

I perceive the human body as a machine 😂😂

Day 1 of a new semester in college. Our 50 yr old H.O.D is a guest lecturer of this new subject called "Industrial Management" (why its included in the syllabus of CSE degree i wonder) . As there were only 6 students , the guy went on like a drunkard telling life lessons :

1) only 20% of the people in a company are only working. Rest 80% of them are just using sugar coated words at the right place ; doing politics and taking credits of the others .

2) those 80% getting benefits are usually the bosses (and in his example, the senior deans and H.O.Ds buttering the administrative dept and director ) and the hardworking 20% are the Juniors or the new joiners ( and in his example, the latest recruited ,honest teachers. Makes sense why we have shitty teachers :/ ). They altogether make sucesses to the company(although its just those 20%hardworkers doing the actual job) . But at the time of salary everybody gets the benfit.

3) Its always perfect to throw blames at senior or junior. (explaining how a parent complaining about the poor study environment to director is made to think that it's only the fault of his own child. blames going from director to dean to HOD to teachers to your own child's mistakes.)

4) Being your boss's favourite is super important. He gave example as : 2 teachers meets him with 100% results and 100% reviews. One of them is a known asshole with 0 knowledge, who makes jokes and sexist comments during the class, gives free attendence and question papers before the exam{therefore 100%reviews} . But he is dean's great ass-licker . The other one is honest hard-working teacher with real reviews and results. So he says he shows their combine results to the director along with his own buttering and ass licking, gets a hike himself and permit to give hije to one junior teacher. And who would it give hike to? The ass licking asshole, because that's how it works. What about the honest teacher?what reply would he get? Simply, appreciations and sugar coated words : "thank you for working so hard. But you did not do anything new. You were only hired to DO hardwork and give good results"

( and i was like fuck? Like seriously? Because that is something resonating with what i once heard in my internship :"yeah you are developing nice and all good, but that's what you are expected to do. You were only hired to achieve results, and you did nothing new". So that's what we are missing? Ass licking?-_- )

5) He believed its important to "look working" than being "actually working" . Quoting an example from his days as a dev, he told a story about how he once worked on a project with deadline of 1 month . He was young and worked hard and in 2 days completed the complete project and accidentally reported success to boss instead of his seniors. The boss simply congratulated his team(seniors and him) and assigned them another project. Later that day , he got an ass-wipe scolding from his seniors that if he had kept his mouth shut, they would have simply watched movies and relax for next 15 days, and submit the project during the salary time to gain bonus attention.
He even gave his short mantra or principle for such situation "kaam ki fickar kar, fickar ka zickar kar, par kaam mat kar " (get worried and tensed about the work. Display your tention and worries to the world (esp bosses) . But don't work.)

And there were many other short stories like that.

Mann, i was about to shout " you corrupt asshole ", but one thing He just told us about the importance of being in boss's good books made me stop ( nd he is a fucking HOD, senior to teachers)

But hell he told some relatable truths. Make me sad about the job life.

Bloody Office politics :|

Funny thing the brain is.

TL;DR; being in the zone is nice. But there is another level of it and, fuck it, I'm loving it!!!

level 0: phased-out, relaxed state. Not focused on anything in particular. Just going with the flow

level 1: aware of the situation and of what's going on, not engaging too much

level 2: alert, ready to react. Constant concentration

level 3: THE ZONE. Time continuum is broken by concentration on the task in front of you - while working on it, time passes faster by magnitudes than when you're in any lower level. Surroundings and periphery do not exist. On;y the task currently in hand exists. Restroom breaks can wait.

level 4: body works on the task by itself. Any cognitive engagement with any of it will only make matters worse. The body knows it better, just let it do the work - let your consciousness sit back and relax, think about something nice. It's a sort of biological version of DMA (direct memory access), bypassing the CPU.

I've only reached level 4 several times, briefly and only while playing BeatSaber. The boxes are flying at me and hands just hit 'em the right way by themselves. Only after the hit, do I realise what my hands did and how cool it actually is. If I try to intentionally look at the boxed and aim for them, I mess it all up. And it's not like muscle memory - level 4 copes with any non-Camellia Expert level, regardless of whether have I played it in the past many times or just a few, several months ago.

I love that feeling!

Found a clever little algorithm for computing the product of all primes between n-m without recomputing them.

We'll start with the product of all primes up to some n.

so [2, 2*3, 2*3*5, 2*3*5*,7..] etc

prods = []
i = 0
total = 1
while i < 100:
....total = total*primes[i]
....prods.append(total)
....i = i + 1

Terrible variable names, can't be arsed at the moment.
The result is a list with the values

2, 6, 30, 210, 2310, 30030, etc.

Now assume you have two factors,with indexes i, and j, where j>i

You can calculate the gap between the two corresponding primes easily.
A gap is defined at the product of all primes that fall between the prime indexes i and j.

To calculate the gap between any two primes, merely look up their index, and then do..
prods[j-1]/prods[i]

That is the product of all primes between the J'th prime and the I'th prime

To get the product of all primes *under* i, you can simply look it up like so:

prods[i-1]

Incidentally, finding a number n that is equivalent to (prods[j+i]/prods[j-i]) for any *possible* value of j and i (regardless of whether you precomputed n from the list generator for prods, or simply iterated n=n+1 fashion), is equivalent to finding an algorithm for generating all prime numbers under n.

Hypothetically you could pick a number N out of a hat, thats a thousand digits long, and it happens to be the product of all primes underneath it.

You could then start generating primes by doing
i = 3
while i < N:
....if (N/k)%1 == 0:
........factors.append(N/k)
....i=i+1

The only caveat is that there should be more false solutions as real ones. In otherwords theres no telling if you found a solution N corresponding to some value of (prods[j+i]/prods[j-i]) without testing the primality of *all* values of k under N.

Ive been working on pseudo-Java (ie some 3rd company's UNDOCUMENTED programming language) that they parse into Java in their backend

It doesnt even support if-else (only ifs and elses) or a boolean combination of False and OR together lmao

mainly a GRPC middleware-language

Given its lack of features (arrays/collections) or documentation, I just had to implement a flag-array using a 0-1 string

Im throwing exceptions unless combined strings equal Lengths and is only 1s

living like in 80s-90s 💀

Should array indexes begin with 0 or with 1?

To end this discussion I propose they begin with 0.5.

Dont blame me for making Minecraft plugins, but holy shit i really hate stairs right now.

Im modifying some old code of mine to add extra features, and i just need to be able to rotate stairs 90, 180 and 270 degrees, then im past this bump.

Stairs get their direction based on a byte value that makes no fucking sense to me.

North = 3
West = 1
East = 0
South = 2

Ive been drawingto see if that made me go "oh like that", checking if the bits of each value had a system, and now im here.

Titshit.
I dont know who made it like this, but i really dont want to make some static switch or if/else statement to process this directional trash. I want it flexible.

If you spotted a system to the numbers, please mail me a rock, and then tell me how i fix this.

So I set up a raspberry pi to control my bedroom lights last year. I decided I wanted to add some more features to it and for the first time since I created it, started looking through the code I wrote.

First thing I noticed was the excessive amount of files I have. Like I get that I just wanted to throw this thing together as quick as I could but did I really need to create a file specifically for storing a 1 or 0 depending if the lights were last turned on or off for a startup check.

Secondly, I seem to have 2 index.html files for some reason.

And finally, the code itself is pure spaghetti. The website is running with a python script, which sends calls to a nodejs server, which executes additional python scripts to control the lights. No comments anywhere, and badly named variables are also a great combo.

And finally there is the occasional "Why the fuck isn't it working, fuck it I'll just unplug the pi and reboot it" that I have been dealing with lately.

Oh and don't forget that the log file is spammed by a debug message that is printed every minute.

God I feel so ashamed. I was proud of this until I looked at it just now.

I had the weirdest job interview in the world. A job that wasn't even considering due to lower compensation than what I am making.

Throughout my career I saw three types of interviews (some times I have 1 & 2, 1&3 or just 2 or just 3 or fail early in 1):

1. HR textbook style: your 3 biggest weaknesses, what would your coworkers describe (I fail most of the time here)

2. People coming to prove a point to you (what happened to me today): Somebody with a clear intention to prove you are stupid and/or lying.. You are guilty until proven innocent style of interaction. They will find one little thing that you read about 15 years ago and zoom in it enough (it takes a 1min read to go over that again) and to them you are stupid and that's it. Generally insecure people do that

3. Tech oriented hiring people: it always goes well even if I don't get hired. Where they focus on the skills that take years to master rather than zooming on something you studied 15 years ago and totally forgot.

The hiring person was in tech presumably for 20 years but I saw 0 important stuff in his github. (I can name and shame if it's allowed here)

The amount of energy spent to just write ‘Hi’ and click a send button is so big that we should consider banning of sending hi messages.

Instead of just saying “Hi!” we are now using analog to digital preprocessors that convert it to bunch of 0 and 1 to send it over communication layer and deliver it to other human being that will convert it from digital to analog by reading it but that is simple.

By sending message using phone we also:
- save it to local phone
- convert it to couple protocols
- transmit it over air so make connection to internet provider services that would generate logs on this provider as well as whole routing table before it gets to the target person
- save it on messaging provider disk
- probably be processed by filters by provider, sometimes be reviewed or listened by third parties and also processed in bulk by artificial intelligence algorithms
- finally delivered to target phone and saved there where that person would just change this text to their inner voice and save it
- sometimes encrypted and decrypted
- sometimes saved on provider
- sometimes saved on phone manufacturer cloud backup
- don’t get me started on people involved to keep this infrastructure in place for you just to say hi

There are also some indirect infinite possibilities of actions for example:
- emit sound and light that can lead to walking from one room to other
- the floor in your house is destroyed cause of it so you need to renovate your floor
- sound can expose your position and kill you if you’re hiding from attacker
- sound can wake you up so you wake up in different hours
- it can stop you from having sex or even lead to divorce as a result simple hi can destroy your life
- can get you fired
- can prevent from suicide and as a result you can make technology to destroy humans

and I can write about sound and light all day but that’s not the point, the point is that every invention makes life more complicated, maybe it saves time but does it really matter ?

I can say that every invention we made didn’t make world simpler. The world is growing with complexity instead.

It’s just because most of those inventions lead to computer that didn’t make our world simpler but made it more complicated.

In my latest installment of "Swift, WTF?", we look at the "if" conditional in terms of the Swift convention of:

if let x = y { /* ... */ }

so what this does :
1. declares x in the scope of the braced code
2. sets x to y (an ahem, "optional")
3. decides if x is not *nil*, then executes the braced code.

This is very similar in both the visual and the operation to the C code of:

if (int x = y) { /* ... */ }

1. declares x in the scope of the braced code
2. sets x to the value of y
3. if x is not zero, then executes the braced code

which is considered *exceptionally* poor style.

Neither the C nor the Swift construct result in a legitimate boolean value of "true" or "false", although C comes closer than Swift.

In the Swift case the *imaginary* "nil" value has to be interpreted as "false" and thus there must be extra code is for the conditional to check on whatever constitutes the **actual** value of nil in Swift and then set the condition to "false".

(remember boys and girls, "optionals" are not real, they are an imaginary language construct of Swift and have no legitimate counterpart in the CPU operations with memory and registers)

At least in the case of C, if the value of x is zero or NULL (which is 0) then it is technically a "false" which in C is 0. Regardless, it is really poor programming and anyone doing that on my team gets an ear full.

But in Swift this obfuscation of code is common and condoned! Well, why not put more of the program in the condition of the if? In fact, stuff the whole thing in there.. why not? 🙄

This just reenforces my opinion that Swift is not a bird but the stuff that comes out of the underside of the bird. 🐦💩

I don't care if a language decides to start their array on 0 or 1...

I just would like every language to stay consistent because I'm tired of trying to figure out why in the hell my array key isn't defined.

Question - is this meaningful or is this retarded?

if

2*3 = 6
2*2 = 4
2*1 = 2
2*0 = 0
2*-1 = -2

then why doesnt this work?

6/3 = 2
6/2 = 3
6/1 = 6
6/0 = 0
6/-1 = -6

if n/0 is forbidden and 1/n returns the inverse of n, why shouldn't zero be its own inverse?

If we're talking "0" as in an infinitely precise definition of zero, then 1/n (where n is arbitrarily close to 0), then the result is an arbitrarily large answer, close to infinite, because any floating point number beneath zero (like an infinitely precise approximation of zero) when inverted, produces a number equal to or greater than 1.

If the multiplicative identity, 1, covers the entire set of integers, then why shouldn't division by zero be the inverse of the multiplicative identity, excluding the entire set? It ONLY returns 0, while anything n*1 ONLY returns n.
This puts even the multiplicative identity in the set covered by its inverse.

Ergo, division by zero produces either 0 or infinity. When theres an infinity in an formula, it sometimes indicates theres been
some misunderstanding or the system isn't fully understood. The simpler approach here would be to say therefore the answer is
not infinity, but zero. Now 'simpler' doesn't always mean "correct", only more elegant.

But if we represent the result of a division as BOTH an integer and mantissa
component, e.x

1.234567 or 0.1234567,

i.e. a float, we can say the integer component is the quotient, and the mantissa
is the remainder.

Logically it makes sense then that division by zero is equivalent to taking the numerator, and leaving it "undistributed".
I.e. shunting it to the remainder, and leaving the quotient as zero.

If we treat this as equivalent of an inversion, we can effectively represent the quotient from denominators of n/0 as 1/n

Meaning even 1/0 has a representation, it just happens to be 0.000...

Therefore

(n * (n/0)) = 1

the multiplicative identity

because

(n* (n/0)) == (n * ( 1/n ))

People who math. Is this a yea or nay in your book?

This is gonna get someone illogically upset, but idc about that.

I know it's ignorance of semantics but I'm tired of propagated ignorance changing the meaning of things.

Non-binary is NOT a legitimate term for whatever 'gender' you are!

I get what *whoever-started-it* was going for, but it's NOT valid. If you want to say that youre not male or female, fine... just don't abuse binary systems to do it. Just say youre non-bool/anti-boolean or identify with one of the, apparently 50, shades of gray.

I keep getting into logical loops to nowhere about this nonsense. No one is even defining what's supposed to be the 1 vs the 0. Which then makes me think '1 must be male... genitalia=1 in many ways...' which then sources back to the historic validity of males vs undervalued/less than human interpretations of females...

Then <brake>.
Ofc these people aren't going into the historical significance... they don't even realise how binary works! Ofc they'd have no clue that all 0s= no data... and 0s only have significance when viewed in placement to the 1s.

Let's all start using proper terminologies, like non-boolean. Maybe i can start a trend by paying people pennies to learn/teach wtf a boolean value is, and that binary can represent anything. With proper encoding the array is limitless... so being binary is actually a giant spectrum... therefore makes no sense to be "non-binary".

Ok... im done. It had to be said.

Who wants to start identifying as non, or educating wtf is, boolean with me???

semi dev related(later half)
A common and random thought I have:

A lot of units that humans use are either needlessly arbitrary or based on something weird. Like Fahrenheit. That shit is weird! 0°F is the freezing point of a water and salt solution. What a weird fucking thing to use!

But also, I like Fahrenheit more. Probably because it's what I was raised with and switching is tedious (though I'm trying. I'd like to use metric more), but also because one degree F is a smaller, more precise change. You can describe more accuracy without decimals.

On the other hand I prefer metric for length. Centimeters, and centimeters are way more precise and way less confusing than inches and .... 1/8th inches? Who the fuck decided on 1/8ths?!

Which brings me to my common thought:

If you look at a Unix timestamp, you can approximate somewhat when it happened. Knowing the current timestamp and a few reference points you can see RELATIVELY what a epoch stamp translates to. A few days ago, an hr ago, 2014ish.

This leads me to think that if we actually taught from a young age to think in epoch as a unit (not as a replacement to normal date formats but as a secondary at first) that we could just naturally read epoch time in the same manner we read dates like "28/01/2006 14:24:10 UTC"

In your brain you automatically know how old you were when that timestamp happened. What grade/job and where you lived at the time. What season it was. You know how far into the day it was, a little before lunch (or after or whatever, your time zone will vary). Now try with 1138458250. I can usually get roughly the year, and month if I really think about it, but that's it. And it takes much more effort

I'm sure there's other units we could benefit from but epoch is the one that usually brings this to mind for me.

Who of you needs some non-disturbing background music while coding?

A while ago I found this in a Youtube-Video from computerphile.
I always listen to it or some variations if I need to stay focused.
Works for me.

Project leader did no work on our project (mainly due to not knowing how to do it), so he dealt with the problem by asking me to explain the entire infrastructure and setup to him five minutes before our call with the Director where he attempted to state all the things that "we" had done.

After his spiel of detail-less crap I explained exactly what was going on, and how I had done it, and the Director seemed far more interested to speak to me.

I'm an intern and the PL has been there full-time for over a year.

I said "I think that meeting went pretty well! He seems happy" after the call and was totally ignored 😂

Intern 1 - 0 Lazy, patronising, rude full-time employee.

TL;DR: If you do fuck all, let the person speak who knows the project inside-out; don't try and get in there first or the hard worker will then go into way more detail than you under to prove their worthiness!

I hate extremist to the point where I became an extremist of hating the extremist.

If life is as simple as 1 and 0, we won't even be fucking evolved and alive till this far.

Every story has different perspectives. Different motives. Is it Kingslayer the one to blame? Is it the Queen's fault? Or was it Little Finger?

We look at one piece of the puzzle and we talk and talk and talk. Well not only do we like to talk our own thoughts out loud, we like to persuade others to join our thoughts. Just like what I'm doing now.

Does this all sound simple as 1 and 0?

This started as an update to my cover story for my Linked In profile, but as I got into a groove writing it, it turned into something more, but I’m not really sure what exactly. It maybe gets a little preachy towards the end so I’m not sure if I want to use it on LI but I figure it might be appreciated here:

In my IT career of nearly 20 years, I have worked on a very wide range of projects. I have worked on everything from mobile apps (both Adroid and iOS) to eCommerce to document management to CMS. I have such a broad technical background that if I am unfamiliar with any technology, there is a very good chance I can pick it up and run with it in a very short timespan.

If you think of the value that team members add to the team as a whole in mathematical terms, you have adders and you have subtractors. I am neither. I am a multiplier. I enjoy coaching, leading and architecture, but I don’t ever want to get out of the code entirely.

For the last 9 years, I have functioned as a technical team lead on a variety of highly successful and highly productive teams. As far as team leads go, I tend to be a bit more hands on. Generally, I manage to actively develop code about 25% of the time to keep my skills sharp and have a clear understanding of my team’s codebase.

Beyond that I also like to review as much of the code coming into the codebase as practical. I do this for 3 reasons. I do this because as a team lead, I am ultimately the one responsible for the quality and stability of the codebase. This also allows me to keep a finger on the pulse of the team, so that I have a better idea of who is struggling and who is outperforming. Finally, I recognize that my way may not necessarily be the best way to do something and I am perfectly willing to admit the same. I have learned just as much if not more by reviewing the work of others than having someone else review my own.

It has been said that if you find a job you love, you’ll never work a day in your life. This describes my relationship with software development perfectly. I have known that I would be writing software in some capacity for a living since I wrote my first “hello world” program in BASIC in the third grade.

I don’t like the term programmer because it has a sense of impersonality to it. I tolerate the title Software Developer, because it’s the industry standard. Personally, I prefer Software Craftsman to any other current vernacular for those that sling code for a living.

All too often is our work compiled into binary form, both literally and figuratively. Our users take for granted the fact that an app “just works”, without thinking about the proper use of layers of abstraction and separation of concerns, Gang of Four design patterns or why an abstract class was used instead of an interface. Take a look at any mediocre app’s review distribution in the App Store. You will inevitably see an inverse bell curve. Lot’s of 4’s and 5’s and lots of (but hopefully not as many) 1’s and not much in the middle. This leads one to believe that even given the subjective nature of a 5 star scale, users still look at things in terms of either “this app works for me” or “this one doesn’t”. It’s all still 1’s and 0’s.

Even as a contributor to many open source projects myself, I’ll be the first to admit that have never sat down and cracked open the Spring Framework to truly appreciate the work that has been poured into it. Yet, when I’m in backend mode, I’m working with Spring nearly every single day.

The moniker Software Craftsman helps to convey the fact that I put my heart and soul into every line of code that I or a member of my team write. An API contract isn’t just well designed or not. Some are better designed than others. Some are better documented than others. Despite the fact that the end result of our work is literally just a bunch of 1’s and 0’s, computer science is not an exact science at all. Anyone who has ever taken 200 lines of Java code and reduced it to less than 50 lines of reactive Kotlin, anyone who has ever hit that Utopia of 100% unit test coverage in a class, or anyone who can actually read that 2-line Perl implementation of the RSA algorithm understands this simple truth.

Anything i try in this life, it fails. I have done hundreds, and have 0 successful projects. When someone asks me "what have you done in these 1/4th of a century existing on this useless floating space rock?" ...... I have nothing to say. It would appear as if I've done Nothing. I have nothing to showcase of projects because its not running live on production. It's all on private repositories. The more i try the harder i fail. I am energy drained. I am uninspired. I am unmotivated. Seeing how some 19 year old NOBODY kid just comes out of nowhere, makes NFT project, scams people for millions of dollars and haves fun in his life and doesnt have to work anymore, is fueling me with RAGE. This is starting to become madness. Am i having too high goals and ambitions and that's why i percieve myself as if im unsuccessful? But how is that possible if a 19 year old nobody is capable of becoming a multi millionaire by scamming people in web3? If i lower my goal expectations, then I have no reason to live. I wouldnt care if i die tomorrow or continue living. I wouldnt bother looking left right while crossing the road because I Do Not Care. What must i do to succeed just Once and meet my goals and expectations? I dont understand. I hate life. Life is empty and meaningless. I have became a Nihilist and i believe in that religion more than anything. It makes no sense that someone scams millions by doing jack shit at a young age while someone struggles and tries hard his whole life and still isnt successful even 0.01% of what the 19 year old is. IT. IS. NOT. FAIR.

When we subtract some number m from another number n, we are essentially creating a relationship between n and m such that whatever the difference is, can be treated as a 'local identity' (relative value of '1') for n, and the base then becomes '(base n/(n-m))%1' (the floating point component).

for example, take any number, say 512
697/(697-512)
3.7675675675675677

here, 697 is a partial multiple of our new value of '1' whose actual value is the difference (697-512) 185 in base 10. proper multiples on this example number line, based on natural numbers, would be
185*1,
185*2
185*3, etc

The translation factor between these number lines becomes

0.7675675675675677

multiplying any base 10 number by this, puts it on the 1:185 integer line.

Once on a number line other than 1:10, you must multiply by the multiplicative identity of the new number line (185 in the case of 1:185), to get integers on the 1:10 integer line back out.

185*0.7675675675675677 for example gives us

185*0.7675675675675677
142.000000000000

This value, pulled from our example, would be 'zero' on the line.

185 becomes the 'multiplicative' identity of the 1:185 line. And 142 becomes the additive identity.

Incidentally the proof of this is trivial to see just by example. if 185 is the multiplicative identity of 697-512, and and 142 is the additive identity of number line 1:185

then any number '1', or k=some integer, (185*(k+0.7675675675675677))%185
should equal 142.

because on the 1:10 number line, any number n%1 == 0

We can start to think of the difference of any two integers n, as the multiplicative identity of a new number line, and the floating point component of quotient of any number n to the difference of any number n-m, as the additive identity.

let n =697
let m = 185
n-m == '1' (for the 1:185 line)

(n-m) * ((n/(n-m))%1) == '0'

As we can see just like on the integer number line, n%1 == 0
or in the case of 1:185, it equals 142, our additive identity.

And now, the purpose of this long convoluted post: all so I could bait people into reading a rant on division by zero.

I am now going to attempt the problem solving ritual.
Requirements:
-have a problem or piece of unoptimized code and you don't know how tk fix/improve it
-be able to sleep/take a nap

Now before I fall asleep the ritual should provide me with an epiphany to solve my problem

Plan b:
I have a class ninja (model), with an observablecollection<property> properties and an observablecollection<gearslot> gearslots;
,a class gear with an observablecollection<property> properties and an Category category:
And a class gearslot with a Gear gear and a Category category;
Via entity framework this results in several property entries per ninja
And several property entries per gear item

All good so far.

I now actually want the ninja property values, to be the sum of the gear property values

So a ninja has int, agi and str of 0.
Gear has 0 or more stats.
If the ninja has two pieces of gear on with agi +1, then the ninja agi should be 2

If possible i would like the logic in the model.
Else i have to put it in the viewmodel.
That i can figure out, its just so inelegant....

Just wanna say that I love devRant b/c :

1. I can write as l33t as I wish knowing that most of u will get the msg, some of u can decode almost anything ( exceptions r the Manuscript and some of AOK posts )

2. I can be sarcastic, say stupid things w/0 fasing a wave of comfused hate

3. speaking 0f which, d re-@ll haters & <spam>3rs r quickly kicked out ( shout 4 all moderators )

4. most of u r critical thinkers and is a pleasure to read some of d discussions

5. one can learn a lot for the other parts of the IT in which is not involved ( yet )

6. It's hell of a fun around you so keep the spirit burning ( might see ya @ burning man, boom, the freshly re-started love parade or just at random point in our small home )

Love ya all. 10x 4 attending this dev/!dev talk

Yo, have some questions for all you Macbook devs here.
#0. What language do you mostly write in?
#1. Do any of you dualboot / use VM's on your Mac?
#2. Is it better or worse (in your experience) to code on a Macbook in general?

Asking bc Im thinking on getting one for The thin and lightness of it.

So, I have a nested ternary, right, and that's not very readable:

(x <= y ? z : (x <= z ? y : x));

The linter points this out and I'm like yeah, valid point. So I inline-F[*0] it:

if (x <= y)
········return z;
else if (x <= z)
········return y;
else
········return x;

Clearer? Kinda. Oh, but the linter doesn't like this either, and to be fair, valid point once again; an else-after-return *can* be quite confusing if you have it in the __middle__ of the F body, catches you by suprise.

However, I'd like to take a brief moment to waggle your nutsack, if you please. Because this is C++ and I'm picking a reference from a list of values, so I can't simply assout[*1] within the switch.

So I'm at the crossroads of life once again, losing man's toughest struggle as I sit on a metaphorical cigar, squirming while I unclench my asshole slowly for strictly defecatory purposes. Allow me to illustrate:

- If I ignore the linter, and leave the rest of the code unchanged, the checks are going to fail and the bot is going to taint my pristine PR with automated comments.
- But if I take the linter's advice, I have to do a slight rewrite of the damn thing plus every F that calls it, which means touching shit that has nothing to do with this issue.

So what's it gonna be? Flushing or shoving my own excrement? Oh, the thrills of it being (literally) SOLID, ie not the acronym, but may the Almighty punish Uncle Bob regardless.

NOTES:
[*0]: It means 'function,' what else?
[*1]: ASS-ign OUT-put, where 'out' is just some var. You modify the var within the F body and return the final value.

i have an idea today for find job as Junior:

First of all, startups usually hire senior devs only for two reasons:

1) is critical to their business, they need people that will ensure the project will be done no matter what, seniors usually brings that to the table.

2) The startups that raise some founding, usually have 100k+ raised, that money is basically enough for hire Seniors for some time without troubles, taking into account they will usually be highly profitable in the mid term, it is not a big deal to take the risk

Today startups, at least the most interesting ones, play the game in God Mode due to that founds raising, it is like having a max level character in some MMO with insane amounts of gold, you will buy only the best gear with that gold, not the low level gear, why you want to buy low level stuff, if you can buy the best of the best? that is why Juniors are not likely to have a place in startups, they can pay the Seniors.

But, there a situation in what an startup will wish to hire some Juniors, this is situation is, when they have never raised founds, they have no Cheat Mode, this ones are usually startups that have just few weeks or months of being created, and they need the MVP ASAP, this startups usually already have one or two Mid/Senior level engineers, but they have a very highly benefit from having a Junior in their team, this guy will no take any part in the Cake, will only work for lot less money and will discharge some stuff from the Seniors (Taking into account that is a minimum competent Junior).

Here is where Juniors can get jobs, at least for start their careers, and taking into account that thousands of new startups are created every year, this is a major market.

Ok, i already test that this approach if viable, i send requests to 5 startups that meets the conditions, and got response from 4! still not make a deal, but this is a lot more than 0 response after 2 dozen of applications to more stablished startups.

What you think about this? maybe this is just the jobless syndrome attacking me fuck

During my first-ever technical interview, the interviewer asked me "Do you know the FizzBuzz problem?"
"Uhh, not really." (I was just thinking ok this problem has a name, must be some algorithm problem)
"So the problem is basically to give you the numbers 1 to 100, if the number is divisible by 3, print 'Fizz', if divisible by 5, print 'Buzz', if divisible by 3 and 5, print 'FizzBuzz'. For other numbers just print out the number itself."

After hearing the problem, I felt so many ideas popping out of my stressed brain.

I thought for a bit and said "ok, so if the digit sum of a number is a multiple of 3, then the number is divisible by 3, and if the last digit is either 0 or 5, it's divisible by 5."
Then I started to code out my solution until the interviewer said "there's an easier solution. Can you think of it?"

This stressed me out even more.

I thought for a bit and said "well, starting from 3, keep a counter that records how many iterations are done after 3. When the counter hits 3, that number would be divisible by 3 for sure. Should I try this solution?"
The interviewer said "Sure." So I started again.

However, I struggled for about another 3min until I realized this solution is a lot harder to implement. The interviewer probably saw my struggle too.

This was the point where he stepped in and asked me "Ummmm there's an easy way of solving this. Have you heard of the MODULO OPERATOR?"

In sheer embarrassment, I finished the code in 30s.

Of course, there was no further question after this, and I felt the need to seriously reevaluate my intelligence afterwards.

I took me the whole day of wondering and debugging to see that I was checking if a variable was 0, to set up some stuff, and the variable was only incremented after that check, but I had a return statement inside of it. So it just went in, saw that it was 0 and returned, over and over. And I was wondering why the fuck nothing happened... because that method got executed every second or so and should've moved the motor.
Gotta love your hardware programming. Either you do it right the very first time, or you spend the whole day staring at a piece of code, compiling, throwing in console prints etc.

Its 1 am, where I live btw.

feature request / rant: there sbkukd be no posting new rants unless you have a minimum amount of +1. Maybe it's 10, or 25. but I've noticed the vast majority of people posting repeated memes, gifs, and overall irrelevant stuff are people with 0-5 +1. they should be required to post comments and be around for a bit to understand what devrant is before clogging up the feed.

Guys I heard a rumor that you like riddles, I'm stuck on my theory project and I'd like to throw a bone:

Say you have a list p = [7,6,2,3,4,5,1,0] and you want to order it, i.e. change it to [0,1,2,3,4,5,6,7], by swapping adjacent elements. Provide an algorithm to do this optimally, when:
a. (Warm-up) each swap costs 1
b. Swaps weight is [4,3,2,1,2,3,4], i.e. if you want to swap position 0 with 1 it'd cost 4, position 3 with 4 will cost 1 and so on.

The optimal overall cost for b is 50 (I did an exhaustive search), however you need to find a general approach which is able to order every list with minimal overall cost (no time constraints as long as the solution is not exponential in the list length), using the provided weight function.

(you get a credit if the solution goes to a paper or anything 😉 it's actually a computer science open problem, but seems possible to me)

StackOverflow locked my account. I'm hoping someone here might be kind enough to help me with a bash script I'm "bashing" my head with. Actually, it's zsh on MacOS if it makes any difference.

I have an input file. Four lines. No blank lines. Each of the four lines has two strings of text delimited by a tab. Each string on either side of the tab is either one word with no spaces or a bunch of words with spaces. Like this (using <tab> as a placeholder here on Devrant for where the tab actually is)

ABC<tab>DEF
GHI<tab>jkl mno pq
RST<tab>UV
wx<tab>Yz

I need to open and read the file, separate them into key-value pairs, and put them into an array for processing. I have this script to do that:

# Get input arguments
search_string_file="$1"
file_path="$2"

# Read search strings and corresponding names from the file and store in arrays
search_strings=()
search_names=()

# Read search strings and corresponding names from the file and store in arrays
while IFS= read -r line || [[ -n "$line" ]]; do
echo "Line: $line"
search_string=$(echo "$line" | awk -F'\t' '{print $1}')
name=$(echo "$line" | awk -F'\t' '{print $2}')
search_strings+=("$search_string")
search_names+=("$name")
done < "$search_string_file"

# Debug: Print the entire array of search strings
echo "Search strings array:"
for (( i=0; i<${#search_strings[@]}; i++ )); do
echo "[$i] ${search_strings[$i]} -- ${search_names[$i]}"
done

However, in the output, I get the following:

Line: ABC<tab>DEF
Line: GHI<tab>jkl mno pq
Line: RST<tab>UV
Line: wx<tab>Yz
Search strings array:
[0] --
[1] ABC -- DEF
[2] GHI -- jkl mno pq
[3] RST -- UV

That's it. I seem to be off by one because that last line...

Line: wx<tab>Yz

never gets added to the array. What I need it to be is:

[0] ABC -- DEF
[1] GHI -- jkl mno pq
[2] RST -- UV
[3] wx -- Yz

What am I doing wrong here?

Thanks.

Stack overflow is full of useless assholes, like I asked a specific question about a problem I am having that is similar to another problem that exists but it is not the same at all in terms of how to fix and instead of helping I’ve got 2 downvotes on it and a comment linking me to a completely unrelated stylistic based question based on something I SAID I HAD ALREADY TRIED CHANGING IN MY QUESTION!!! Here’s my question btw in case anyone can help here before I smash up my laptop 😑:
I have a piece of code in which I am trying to read in words which have been categorised using a number and then placed in a text file in the following format "word-number-" with a new line for each word. However, despite not mixing cin>> and getline and having tried a number of methods I still cannot get it working.
So far I have attempted using a cin.ignore() call to clear any '\n' char's from the buffer, as well as checking if the file is opening in the first place (it is), and using the >> operator instead throughout my code however I could not get that working either. When I place the get line call inside the condition of the while loop, the while loop doesn't run, however when I make the while loop condition a .eof() call it will run once however when I try to print the text that has been read from the getline call it just prints a blank line.
if(file.is_open()){
while(!file.eof()){
getline(file, text, '-');
count++;
cout<<count<<endl;
cout<<text<<endl;
if(count%2 == 1){
wordBuff = text;
}else if(count%2 == 0){
if(stoi(text) == wordClass){
wordList.push_back(wordBuff);
}
}
}
file.close();
}
While I recognise there are a lot of other questions on this out there I cannot seem to get any of their solutions to work and the vast number being related to people mixing the >> operator and getline doesn't help, so any tips or solutions will be of great help

"Most memorable bug you fixed?"

A recent instance happened in one of my Scratch projects, and the bug involved "Infinities."

I had an opportunity to teach kids programming, and it involved Scratch. So, to have something to show those kids at least, I decided to make a small game.
In that game, I had an object that takes some time before appearing after being cloned (i.e., instantiated.) The duration was calculated by dividing a constant with a variable:
[Wait for ((3) / (variable)) seconds]
The bug is that I forgot about the case where 'variable' can be 0, which is classic and insignificant.

Well, the thing is that I learned two things the hard way:
1: Scratch is very flexible about integers and floats (e.g., at one second, it looks like an integer, but one operation later, it's a float.)
2: Scratch does not provide any 'runtime errors' that can crash the project.

In other languages, similar "wait" methods take "milliseconds" in an integer, so it would have barfed out a "DivideByZeroException" or something. But Scratch was so robust against project-crashing behavior that it literally waited for f*<king "infinity seconds," effectively hanging that clone without warning or runtime errors. This masked my bug. It took way too long to debug that s#!+.

Don't blanket-mask any errors.

Naaarf

Refactoring the whole day.

Someone who prefers while(list(...) = each(...)) or for($x=0; $x < count($array); $x++) wrote the following code, too.

if ($indexed == null || $indexed == "0" && $row[$x]["indexed"] == 0 || $indexed == "1" && $row[$x]["indexed"] == 1) ....

It's buggy. Why does this not surprise me?

This stuff. Whole day.

My brain feels foggy.

The near future is in IOT and device programming...
In ten years most of us will have some kind of central control and more and more stuff connected to IOT, security will be even a bigger problem with all the Firmware bugs and 0-day exploits, and In 10 years IOT programmers will be like today's plumbers... You need one to make a custom build and you must pay an excessive hour salary.
My country is already getting Ready, I'm starting next month a 1-year course on automation and electronics programming paid by the government.

On the other hand, most users will use fewer computers and more tablets and phones, meaning jobs in the backend and device apps programming and less in general computer programs for the general public.

Programmers jobs will increase as general jobs decrease, as many jobs will be replaced by machines, but such machines still need to be programmed, meaning trading 10 low-level jobs for 1 or 2 programming jobs.

Unlike most job areas, self-tough and Bootcamp programmers will have a chance for a job, as experience and knowledge will be more important than a "canudo" (Portuguese expression for the paper you get at the end of a university course). And we will see an increase of Programmer jobs class, with lower paid jobs for less experienced and more well-paid jobs for engineers.

In 10 years the market will be flooded with programmers and computer engineers, as many countries are investing in computer classes in the first years of the kids, So most kids will know at least one programming language at the end of their school and more about computers than most people these days.

Similar to how some measure distance to the city with time or km, do you prefer measuring a job with hours or money?

Ex[0]: this is a 20k job.
Ex[1]: this is a 40h job.

Tldr:
Can't fucking figure out why I'm the only one who can't solve a DP problem in code, when me and friends use the same idea and no one knows why only mine doesn't work...

We are given a task to solve a problem using DP. My friends write their code with the same idea as a solution. Copying the code is not allowed. I follow the same idea but my code won't work. Others look into it, in case they find errors. They can't find any.

The problem (for reference):
Given a fixed list of int's a = (a_1,a_2,...,a_n) and b = (b_1,b_2,...,b_n), a_i and b_i >= 0, a.length == b.length
We want to maximize the sum of a_i's chosen. Every a_i is connected with the b_i at the same index. b_i tells us how many indexes of a we have to skip if choosing the corresponding a_i, so list index of b_i + b_i's value + 1 would be the position of the next a_i available.

The idea:
Create a new list c with same length as a (or b).
Begin at the end of c and save a_n at the same position in c. Iterate backwards through c and at each position add the max value of all previously saved values of c (with regards to the b_i-restriction) with the current a_i, else a_i + 0 if the b_i-resctriction goes beyond the list.
Return the max value of c.

How does that not work for me but for the others?? Funny enough, a few given samples work with my code. I'm questioning my coding ability...

Client: Can't you make the autoload column in wp_options 1/0 so it loads quicker?

Me: So you want me to redevelop WordPress? Or build you a custom platform?

How coding has impacted my life?

Lol, mann I don't think normal anymore. Everything is logical and conditional statements to me now. If this, do that! Else, do this. I've been making people think 2x about their dumb questions to fix their broken phones, computer screens and yes, the popular one.."can you hack facebook?". I can't even do a simple renaming or count without start with a 0. Normal people start like 1, 2, 3, 4.... and I'm like 0, 1, 2, 3. Bruh, I'd rather code than hang out which I still do but less now..smh

I do contracting for different companies who get too much work on their hands and a deadline on their ass, and it’s always a trip to see how amateurish some of their developers are.

Like who the fuck names a major variable ‘abc’ or ‘xyz’ !!!!

Also they clearly don’t know how to ask equivalence if statements as I got a chain of if else statements that were written like

if (decision>0 && decision<2)
//Code
else if (decision>1 && decision<3) ...etc

So at one point I worked on an inherited project that had the worst code I've ever seen. I mean bad, so bad there may no quantifiable measure that can accurately convey how bad. We ended up naming the thing 'the hydra', cause it had a million issues and they just kept growing as we fixed things. To my point, in C++ they implemented their own primitive type Boolean32 as a signed int32 pointer. If that wasn't enough they used it as an octal bit mask. They also switch the value using logical and / or between 2 numbers, 037777777777 and 000000000001. So essentially they only switch this value to 1 or -1 and end up comparing it to their own const true or false. In c++ any value not 0 is == true...apparently not in this code.

I'm wondering.. Chinese have built all sorts of things we never knew we need in our lives. I'm wondering, is there anywhere a physical smartphone keyboard I could purchase? The old-school numpad, like on nokia 3310 or so.

I sometimes find myself in situations where I'd like to type the whole message w/o looking at the screen. Touch-keyboards make this an impossible goal. Having an old-school physical kbd would be perfect for the job!

So I promised a post after work last night, discussing the new factorization technique.

As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.

697 becomes -> 600, 90, and 7.

It then factors *those* to give a decomposition matrix that looks something like the following when printed out:

offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]

offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]

offset: 1, exp: [[Decimal('7'), Decimal('1')]]

Each entry is a pair of numbers representing a prime base and an exponent.

Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.

So for offset three (600) here, we're looking at

2^3 * 3 ^ 1 * 5 ^ 2.

But actually we're searching

2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1

etc..

On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.

And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.

So by implication we can filter out any product of this exponent search that is greater than the square root of n.

Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.

Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.

And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.

It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.

But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.

For example, for one particular semiprime n=pq, this was some of the data:

n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]

q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]

It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.

And I found this rule held each time I tested it.

Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.

I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.

This was ripe for a decision tree generated through random search.

Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]

n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]

Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]

And so it was clear from the get go that this approach held promise.

From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.

It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.

Im building a dead simple online store. So far the options are:
0) heroku, with redis
1) aws lambda functions and some aws storage
2) set up a vps

The domain will be a cheap .store domain, and 1 and 2 should not exceed the limit where its not free anymore. I dont want wordpress or anything premade, i dont expect more than 50 orders. Is there a more stupid solution that lets me try out different providers?

Grrrr

I love JS, but I hate browsers.

Universal ES5 way to initialize a date from a input value in "dd.mm.YYYY" format:

var split = input.value.split('.');
var from = {};
from.day = parseInt(split[0]);
from.month = parseInt(split[1])-1;
from.year = parseInt(split[2]);

var myDate = new Date(from.year, from.month, from.day);
// if a timestamp format is needed:
var myDateTimestamp = +new Date(from.year, from.month, from.day);

No, I won't use moment.js or other bloat-braries just for fucking dates.

Was just fucking around with MyBB in order to figure out how it works on the control panel - whatever, right? Install a crap ton of plugins, and quite a lot of them wouldn't install due to an SQL statement being wrong. I check them, and either:

- the plugin ID is specified (it's auto-increment, it really shouldn't be specified at all)
- the database expected an integer and instead got a word

like for fucks sake, it's either 1 or 0 for being default, yet a lot of developers PUT YES OR NO?? HOW IS THAT EVEN REMOTELY AN INTEGER WHAT THE FUCK

So that was my past hour, running through plugin files, finding SQL statements and altering them. Safe to say that for what I got out of the plugins, it really wasn't worth it.

What do you prefer:

for(int i = 0; i <= maxValue; i++)

Or

for(int i = 0; i < maxValue + 1; i++)

The data at the bottom are statistics regarding my key presses. It's literally every key pressed on this laptop since 2024-12-08. Since that date I entered a total of unique 925450 unique inputs. I did 4751951 keyboard inputs.

I know from 595 hours exactly what i've done for tasks (described by LLM based on my keylog data).

I type 107 lines per hour on average (return presses) based on 595 hours. With that logic, i did around 63925 lines.

I'm not very happy with the statistics, especially not because backspace is a hardcore first. Now, while i'm typing i'm focusing on how much I use it and it's not a lot at all.

But the thing is, if you remove abcdef, you have one a, one b, but six times back space. And these are real presses - not keyboard repeats. Also abcdef will be counted by the tag counter as a whole. Everything is a tag until it sees a new line or a white space or some punct.

Funny is that there are completely different keys on the list than I expected. You're so you used to those keys that you don't even notice using them.

I'm almost considering to add a sound under the backspace button to teach myself WHEN i use it and try to avoid it.

The key logger database is now 346Mb. Some overhead because every keypress takes around 40 chars of description (timestamp, press type, char, input device).

Creating statistics for the tags (unique words typed) takes several minutes. Already rewriting that part to C. The stats are made by python, the key logs with C.

I'm just shocked, I used 144644 times a key that I think not to use that much? :P How retoorded can you be. Imagine if i actually fixed typo's :P

But based on these keys you can see that i'm mainly working in terminal / vim. The 'i' for insert for example, typed so many times. The 'x' for save+quit. The '0' to go to beginning of line.

Did you expect that these buttons would've been the most used?

#0 BACKSPACE is pressed 144644 times (15.63% of total input)
#1 UP is pressed 92711 times (10.02% of total input)
#2 LEFT_SHIFT is pressed 73777 times (7.97% of total input)
#3 ENTER is pressed 63883 times (6.9% of total input)
#4 DOWN is pressed 56838 times (6.14% of total input)
#5 TAB is pressed 43635 times (4.72% of total input)
#6 RIGHT is pressed 37710 times (4.07% of total input)
#7 SPACE is pressed 34438 times (3.72% of total input)
#8 LEFT is pressed 26800 times (2.9% of total input)
#9 LEFT_CTRL is pressed 25402 times (2.74% of total input)
#10 LEFT_ALT is pressed 17289 times (1.87% of total input)
#11 I is pressed 12856 times (1.39% of total input)
#12 X is pressed 6106 times (0.66% of total input)
#13 A is pressed 5163 times (0.56% of total input)
#14 0 is pressed 4487 times (0.48% of total input)
#15 PAGEDOWN is pressed 4151 times (0.45% of total input)

Tomorrow i have to go into the office and work for 8 hours for $0/hour, building a project that includes backend in java, bash scripting, ci/cd and building the whole devops infrastructure and deploying that backend on cloud provider through terraform docker kubernetes, aside from being tested in theory for those 8 hours in-person,

all of this as a form of 1 technical interview after which they will decide if they move forward with me or reject me.

Do you think this is fair?

So we are looking for a ML summer intern.
The amount of fake ML genius is astonishing.

These kids would put projects like "increased state of the art vision transformer model for automated guided missiles technology by 500%, leading to the destruction of ISIS in Irak and Syria", and then proceed to be unable to give you the derivative of Relu(x)=Max{x, 0} which is 1 or 0, or explain what batch normalization is ?

Just figured out "code map" and "code clones" on VS 2015 (don't ask me why I didn't know these features)

Thought I should try it on my newly created application for a client (+/- 1500 lines of code C#)

Came across 1 duplication, 0 unreferenced classes or members and no circular references

I'm just awesome

A beginner in learning java. I was beating around the bushes on internet from past a decade . As per my understanding upto now. Let us suppose a bottle of water. Here the bottle may be considered as CLASS and water in it be objects(atoms), obejcts may be of same kind and other may differ in some properties. Other way of understanding would be human being is CLASS and MALE Female be objects of Class Human Being. Here again in this Scenario objects may differ in properties such as gender, age, body parts. Zoo might be a class and animals(object), elephants(objects), tigers(objects) and others too, Above human contents too can be added for properties such as in in Zoo class male, female, body parts, age, eating habits, crawlers, four legged, two legged, flying, water animals, mammals, herbivores, Carnivores.. Whatever.. This is upto my understanding. If any corrections always welcome. Will be happy if my answer modified, comment below.

And for basic level.

Learn from input, output devices

Then memory wise cache(quick access), RAM(runtime access temporary memory), Hard disk (permanent memory) all will be in CPU machine. Suppose to express above memory clearly as per my knowledge now am writing this answer with mobile net on. If a suddenly switch off my phone during this time and switch on.Cache runs for instant access of navigation,network etc.RAM-temporary My quora answer will be lost as it was storing in RAM before switch off . But my quora app, my gallery and others will be on permanent internal storage(in PC hard disks generally) won't be affected. This all happens in CPU right. Okay now one question, who manages all these commands, input, outputs. That's Software may be Windows, Mac ios, Android for mobiles. These are all the managers for computer componential setup for different OS's.

Java is high level language, where as computers understand only binary or low level language or binary code such as 0’s and 1’s. It understand only 00101,1110000101,0010,1100(let these be ABCD in binary). For numbers code in 0 and 1’s, small case will be in 0 and 1s and other symbols too. These will be coverted in byte code by JVM java virtual machine. The program we write will be given to JVM it acts as interpreter. But not in C'.

Let us C…

Do comment. Thank you

I'm doing a project for uni in Omnet (C++ framework that should facilitate working with networks of queues, simulating and displaying statistics).

I needed to retrieve a random value from an exponential distribution, and the function to do so requires a random number generator as input. The framework has 2 implementations of the RNG and I picked the first one.

I spent 3 hours trying every possible thing, using both the exponential() function and its class wrapper (both provided by the framework), it was always returning 0 or NaN.

The RNG was spitting out values correctly, so I thought it was okay.

When I was almost ready to give up, I figured I could try and change to the second implementation of RNG, expecting nothing to change. And it fucking worked.

Zero reports on this behavior on Google, no apparent reason why it would work with one and not with the other when the two RNGs literally implement the same abstract class and spit out the same exact numbers... Just black magic...

Oh and cherry on top, it works with the raw function but not with the class wrapper on that same function... IF YOU GOTTA IMPLEMENT SOMETHING IN YOUR DAMN FRAMEWORK THAT DOESN'T WORK, FUCKING DON'T! 1 combination working out of 4 is not good! Or at least document it!

Sorry just had to share my pain

As i was shitting on toilet I realized something very important. This could be THE answer.

The question: what is the formula for achieving success? I realized this must be THE ultimate answer:

Money + connections + luck >= success

Why?

MONEY:
You must have money to make more money.

CONNECTIONS:
Some average joe can tell his friend Cockty to phone call his friend Dickson who's a good friend with Cumston to message his millionaire friend Asslicker who is gonna help the average joe succeed.

LUCK:
No matter what you do or how hard you work, how many achievements you have or degrees, you can spend 10 million dollars on a project -- and still fail because you're not lucky.

Let's calculate this probability:

have = 1
missing = -1
money = 0
connections = 0
luck = 0
success = 1

money + connections + luck >= success

Case 1 (have everything):
have + have + have >= success
1 + 1 + 1 >= 1
3 >= 1 ✅

Case 2 (no money):
missing + have + have >= success
-1 + 1 + 1 >= 1
1 >= 1 ✅

Case 3 (no connections):
have + missing + have >= success
1 - 1 + 1 >= 1
1 >= 1 ✅

Case 4 (no luck):
have + have + missing >= success
1 + 1 - 1 >= 1
1 >= 1 ✅

Case 5 (no money, no connections):
missing + missing + have >= success
-1 - 1 + 1 >= 1
-1 >= 1 ❌

Case 6 (no money, no luck):
missing + have + missing >= success
-1 + 1 - 1 >= 1
-1 >= 1 ❌

Case 7 (no connections, no luck):
have + missing + missing >= success
1 - 1 - 1 >= 1
-1 >= 1 ❌

Case 8 (no money, no connections, no luck):
missing + missing + missing >= success
-1 - 1 - 1 >= 1
-3 >= 1 ❌

We have: 4 possible outcomes that we want, k=4

Out of total: 8 possible combinations, n=8

Probability of achieving success using this formula is: P(A) = k/n = 4/8= 0.5 * 100% = 50% chance of being successful in this shit life

This is correct in theory. HOWEVER:
Case 1: someone having
- a lot of money
- a lot of connections
- a lot of luck
In practicality is damn near IMPOSSIBLE

Maybe 1 in 100 million people are born like this. That's 100,000,000 people / 8,000,000,000 people = 0.0125 * 100% = 1.25% of people are this blessed and gifted in life. This might be even less so we can ignore this probability as a possible outcome and average it out to realistic average joe daily life.

Therefore giving us a total of 7 combinations, 3 possibilities to succeed in this shit life

So: k/n = 3/7 = 0.4285 * 100% = 42.85% chance to be successful in this shit life

Mathematically proven how life is pure trash

Funny enough we can round it to 42%. And 42 is the answer to life, universe and everything in existence

Are you 1 or 0....
