Why do some non-devs treat professional app development like some kids craft-making hobby that requires zero skill and knowledge or brain?
A friend (with ZERO knowledge about coding) said to me today, teach me, or tell me how to learn this app development, I'll learn it within a month and make my own apps plus do freelance app work in free time, apps fetch plenty of money easily. Blah blah.
Not the first time, other non dev friends have talked in the same way on other instances.
It's insulting and infuriating. I don't even know what to reply.7 -
TL;DR: I dont work in IT, but I code at work, and the non-IT higher-ups lack of knowledge shows brutally.
So I work in aviation, not IT. Through coincidences, I was tasked to work on our flight plan distribution logic years ago, which was then written in BRL (Business Rule Language). In lockdown 2020, I finally started to learn "real" programming with Python, but soon shifted to Java. Which was good, since all of a sudden a few months ago the company ditched BRL and the godawful IBM ODM IDE for... Java and IntelliJ. Nice. BUT my teammates have zero clue about Java and no real inclination to learn it by themselves. So I have been appointed their mentor, despite me stating Im still a beginner myself. Its somewhat doable, I get the hard problems, they do basic maintenace, basically renaming variables and stuff. One of my yearly goals is to make sure a completely new guy is able to do everything I do by september. It took a LOT to talk them out of it.
In my last yearly review I got some flak for not "selling" myself to other teams enough, whatever that means. So, as a learning project, I designed a new intranet page for our department in Javascript. Its loved by all. It has links to all the stuff we need woth a nice interface and built in tools to make work easier and more efficient. I did it on my own, in my spare time, simply because I was fed up with the old crap and it was an enormously good learning opportunity. Now they want to give some other guy the responsibility over that page/tool because apparently it is "not in my process team description". They even planned a day for me and him so he can "learn Javascript then". Suuure...
I also did a digital checklist tool as a webapp. All this runs from a local folder, no server at all because reasons. I made it work. Now they want it integrated into some other tool some other guy made. He wrote his tool in PHP entirely so merging the two will take considerable time. Which I told them multiple times. No, it does not take about two hours.
Sometimes, comrades, sometimes....
Im still grateful for the opportunity to code at work but the lack of knowledge really REALLY shows. My goal now is to talk management into paying for a Java course for me (they are very expensive here). That way, they get a better employee and I get more knowledge and an actual certificate thats worth something. Usually in this company, this has higher chances of success than straight up asking for more money.
Sorry for the long story, but it felt good just typing it all out, even if nobody reads this.4 -
My Girlfriend broke with me today.
We was in this relationship from two years now. we was doing very good, our relationship was not toxic, no fights, no bad words, zero problems.
One month ago she goes to travel with her evangelical aunt to the beach. Her aunt have lot of money she gets from scamming all that believers. I was happy for my ex-gf because here in out city she was having lot of problems of health, mainly because she was not very mind stable and that degraded her health.
When she goes, her physical and mental health improve a lot. i was happy she is stable now. Her aunt have some Church around the city they go, aunt started to bring her very often to the church. She started to strongly reinforce they God beliefs.
Of course im atheist, she know that from very long time ago. But of course when she started to be more devoted, feels dont fit with me. I refuse to change my mindset about that topic.
Today she says we must broke because im not a believer. This was the most painful experience in my life. I fall in cry for three hours. I truly love her. I recently wakeup and decide to write this rant. I dont have too much friends to talk apart from her. So i wish to share this here.
Im unemployed, she was my only support all this job hunting times. Now she was gone and im alone, this hurts a lot.
Im trying to dont fall deep af, to non return path.
Fuck religion. and her fanatic aunt.31 -
New to this but here's my rant I suppose. It bothers me how "non-tech" people kind of devalue what tech people do. Like they have zero understanding of it, so you make something in 30 minutes or an hour that took years of building said skills and involved complex logic and understanding of relational data and because it only took you 30 minutes or an hour it must have been "easy". Or the way you are everybody's free tech advisor with family and friends... And things are said like "I'm not good with this stuff, but you're so good with it". For the record nobody is just "great" at technology or coding from birth its been a 2+ decade craft that I've experimented with and learned and put effort into. So taking into consideration all this effort I have put in to understand all this you say you'll never remember to push that button so you'll just ask me again when the problem arises. Yes because its so fun for me to constantly maintain your electronics because you can't bother to remember to push a button.5

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 ==...7 -
My last job before going freelance. It started as great startup, but as time passed and the company grew, it all went down the drain and turned into a pretty crappy culture.
Once one of the local "darling" startups, it's now widely known in the local community for low salaries and crazy employee churn.
Management sells this great "startup culture", but reality is wildly different. Not sure if the management believes in what the are selling, or if they know they are selling BS.
- The recurring motto of "Work smarter, not harder" is the biggest BS of them all. Recurring pressure to work unpaid overtime. Not overt, because that's illegal, but you face judgement if you don't comply, and you'll eventually see consequences like lack of raises, or being passed for promotions in favour of less competent people that are willing to comply.
- Expectation management is worse than non-existent. Worse, because they actually feed expectations they have no intention of delivering on. (I.e, career progression, salary bumps and so on)
- Management is (rightfully) proud of hiring talented people, but then treat almost everyone like they're stupid.
- Feedback is consistently ignored.
- Senior people leave. Replace them with cheap juniors. Promote the few juniors that stay for more than 12 months to middle-management positions and wonder where things went wrong.
- People who rock the boat about the bad culture or the shitty stunts that management occasionally pulls get pushed out.
- Get everyone working overtime for a week to setup a venue for a large event, abroad, while you have everyone in bunk rooms at the cheapest hostel you could find and you don't even cover all meal expenses. No staff hired to setup the venue, so this includes heavy lifting of all sorts. Fly them on the cheapest fares, ensuring nobody gets a direct flight and has a good few hours of layover. Fly them on the weekend, to make sure nobody is "wasting time" travelling during work hours. Then call this a team building.
This is a tech recruitment company that makes a big fuss about how tech recruitment is broken and toxic...
Also a company that wants to use ML and AI to match candidates to jobs and build a sophisticated product, and wanted a stronger "Engineering culture" not so long ago. Meanwhile:
- Engineering is shoved into the back seat. Major company and product decisions made without input from anyone on the engineering side of things, including the product roadmaps.
- Product lead is an inexperienced kid with zero tech background -> Promote him to also manage the developers as part of the product team while getting rid of your tech lead.
- Dev team is essentially seen by management as an assembly line for features. Dev salaries are now well below market average, and they wonder why it's hard to recruit good devs. (Again, this is a tech recruitment company)1 -
Updated a website for an older client today. Realized I originally wrote their website in 2002.
That web site is a fucking non-responsive piece of shit... but it is still running normally after 18 years.
Just HTML/CSS and some light JS/PHP for form processing. It's not fancy but it still performs and works perfect on Desktop and OK on mobile. Mobile devices which DID NOT EXIST when I wrote it.
Let this be a lesson to the entire new class of developers who seems to think you need some framework to develop. You don't. And I GUARANTEE if that site used any framework that framework would have been retired or updated to un-useability 10 years ago.
Meanwhile my LAMP ass "web native" shit spaghetti with ZERO DEPENDENCIES is still just chugging the fuck along.4 -
Unpopular opinion: I actually tend to not use adblock as much recently, and think its reasonable to have non aggressive ads on websites, and support content creators. Also, people here that show zero tolerance policy towards any advertisement are really interesting to me to say the least.10

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)

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.4 -
Two big moments today:
1. Holy hell, how did I ever get on without a proper debugger? Was debugging some old code by eye (following along and keeping track mentally, of what the variables should be and what each step did). That didn't work because the code isn't intuitive. Tried the print() method, old reliable as it were. Kinda worked but didn't give me enough fine-grain control.
Bit the bullet and installed Wing IDE for python. And bam, it hit me. How did I ever live without step-through, and breakpoints before now?
2. Remember that non-sieve prime generator I wrote a while back? (well maybe some of you do). The one that generated quasi lucas carmichael (QLC) numbers? Well thats what I managed to debug. I figured out why it wasn't working. Last time I released it, I included two core methods, genprimes() and nextPrime(). The first generates a list of primes accurately, up to some n, and only needs a small handful of QLC numbers filtered out after the fact (because the set of primes generated and the set of QLC numbers overlap. Well I think they call it an embedding, as in QLC is included in the series generated by genprimes, but not the converse, but I digress).
nextPrime() was supposed to take any arbitrary n above zero, and accurately return the nearest prime number above the argument. But for some reason when it started, it would return 2,3,5,6...but genprimes() would work fine for some reason.
So genprimes loops over an index, i, and tests it for primality. It begins by entering the loop, and doing "result = gffi(i)".
This calls into something a function that runs four tests on the argument passed to it. I won't go into detail here about what those are because I don't even remember how I came up with them (I'll make a separate post when the code is fully fixed).
If the number fails any of these tests then gffi would just return the value of i that was passed to it, unaltered. Otherwise, if it did pass all of them, it would return i+1.
And once back in genPrimes() we would check if the variable 'result' was greater than the loop index. And if it was, then it was either prime (comparatively plentiful) or a QLC number (comparatively rare)--these two types and no others.
nextPrime() was only taking n, and didn't have this index to compare to, so the prior steps in genprimes were acting as a filter that nextPrime() didn't have, while internally gffi() was returning not only primes, and QLCs, but also plenty of composite numbers.
Now *why* that last step in genPrimes() was filtering out all the composites, idk.
But now that I understand whats going on I can fix it and hypothetically it should be possible to enter a positive n of any size, and without additional primality checks (such as is done with sieves, where you have to check off multiples of n), get the nearest prime numbers. Of course I'm not familiar enough with prime number generation to know if thats an achievement or worthwhile mentioning, so if anyone *is* familiar, and how something like that holds up compared to other linear generators (O(n)?), I'd be interested to hear about it.
I also am working on filtering out the intersection of the sets (QLC numbers), which I'm pretty sure I figured out how to incorporate into the prime generator itself.
I also think it may be possible to generator primes even faster, using the carmichael numbers or related set--or even derive a function that maps one set of upper-and-lower bounds around a semiprime, and map those same bounds to carmichael numbers that act as the upper and lower bound numbers on the factors of a semiprime.
Meanwhile I'm also looking into testing the prime generator on a larger set of numbers (to make sure it doesn't fail at large values of n) and so I'm looking for more computing power if anyone has it on hand, or is willing to test it at sufficiently large bit lengths (512, 1024, etc).
Lastly, the earlier work I posted (linked below), I realized could be applied with ECM to greatly reduce the smallest factor of a large number.
If ECM, being one of the best methods available, only handles 50-60 digit numbers, & your factors are 70+ digits, then being able to transform your semiprime product into another product tree thats non-semiprime, with factors that ARE in range of ECM, and which *does* contain either of the original factors, means products that *were not* formally factorable by ECM, *could* be now.
That wouldn't have been possible though withput enormous help from many others such as hitko who took the time to explain the solution was a form of modular exponentiation, Fast-Nop who contributed on other threads, Voxera who did as well, and support from Scor in particular, and many others.
Thank you all. And more to come.

Who am I?
Some of you, because of the hyperbolic, outrageous, trollish, and often self-satirical nature of my posts, might doubt me. Thats completely relatable.
Heres the truth:
I was diagnosed in childhood with ADHD, fucking everyone, every male, these days is diagnosed with that. I was diagnosed bipolar. Hell anyone reading my posts could see that from a mile away. I was diagnosed on the borderline personality spectrum. Yeah, I could see that.
I was tested. They said I was in the 98th percentile for clerical ability, not extraordinary but pretty good, mathematical ability a little higher than that. My SAT was 1491. Not yale material, but I coulda been someone.
Over the years I studied a LOT of politics and read a metric fuckton of books. (40+ books over the course of three years).
I predicted every single presidential election since bush juniors second election. Three supreme court picks. Senatorial elections. Congresional elections. More than that.
I have a better analysis track record than some of the multidecade analysts sitting in the fucking NSA.
No I am not shitting you. No I am not exaggerating.
It's about the only claim to fame I get to legitimately make.
People ask me, "then why aren't you famous?"
How do you know I'm not.
Look I'm gonna tell you my actual name.
My real name is Lawrence B. Lindsey
Okay, I'm bullshitting for fun. But words I have written on alt twitter accounts have legitimately come out of presidential hopeful's mouths. No, this I am *not* bullshitting you about.
Imagine that. A guy who lived in his parents attic for five years, writing words that came out of presidential candidates mouths.
At one time I was about as popular and influential as that fuckboy catturd.
yes, really. No I am not fucking joking.
Under normal conditions I wouldn't talk about this or reveal it, because who the fuck cares? I'm just some dude on the internet, drunk, both on alcohol, and the pseudo-anonymous equivalent of bragging rights.
You know how many women I turned down because I could? You know how fucking drunk I am? They say a drunk man's words are a sober man's thoughts. Well, I'm not usually honest like this because the internet is full of false braggarts, and you tell people the truth and they don't fucking believe you.
I swear, it seems like I made some faustian bargain at some time, and can achieve no fame or lasting wealth in my life--to save my life.
Shit, I was talking to a chinese women who ran a bank in china (yes, really), who advised me to buy into bitcoin early on. Didn't have the money to. Woulda been a fucking millionaire if I did.
*Non-obvious* Ideas that major corporations are now persuing? Yeah those were sitting in my card index since the early 2000s.
I helped two people build and sell businesses. One for me tens of thousands. Another for millions. Yes, really. Got zero, and I mean, *zero* credit for it.
Point is, doesn't matter how famous you are, or coulda been, Doesn't matter the ideas you have, or had.
The world doesn't promote runners-up, or hasbeens, or wannabes, or could-bes.
What matters is execution.
If you're wandering through life, wondering when you're lucky break will be, stop. You have to realize, you make your own luck. Recognize the difference between what you can control, and what you can, and work on promoting your own ideas or business or values, instead of other people's dreams.
And for those wondering, yes I am drunk, and no, I ain't fucking kidding you in anything I wrote here.
The most important lesson I learned is this:
First work on your own success, before you work on the success of others.
p.s.
I give surprisingly good advice for someone who doesn't benchmark well on traditional measures of success. I know, even I was shocked when I looked at the statistics.33 -
While coding in C, I once forgot to add a semicolon at the end of a while loop polling a register value.
The logic required me to make it zero as soon as it read non-zero and continue the rest of the process. Hence the 'while' that missed the semicolon ended up being a single instruction assignment to the same volatile register that I kept polling. This caused synchronisation issue with the FPGA, and my code got stuck in an uncertain infinite loop.
Took me 2 days and a silly, yet valid question from my teammate to figure out the cause of this stupid bug.8 -
why do i feel like sOfTwArE cErTifiCaTiOnS are the biggest scam in the world
literally zero prediction of the quality of work you will produce, cuz you could float through them anyway

correct me if i'm wrong; are there certifications of the equivalent rigor like the fundamentals of engineering (fe) exam? in this sense, our industry is far behind... though to be fair 90% of software is non life / operational critical like building a freaking bridge is10 -

*Me: “Perhaps this simple and concise way to ensure the user doesn’t lose their data before they leave the page that requires non-zero yet minimal input from the user. (Read: ya gotta push a save/submit button)”
*Everyone else: Let’s pretend to read the user’s mind and perform relatively complicated functions behind the scenes, of which the user will most likely be unaware, that will add an undetermined amount of complexity to the development because we think it’s “where things are going,” by saving the value of a certain HTML element as it loses focus.

Aren't you, software engineer, ashamed of being employed by Apple? How can you work for a company that lives and shit on the heads of millions of fellow developers like a giant tech leech?
Assuming you can find a sounding excuse for yourself, pretending its market's fault and not your shitty greed that lets you work for a company with incredibly malicious product, sales, marketing and support policies, how can you not feel your coders-pride being melted under BILLIONS of complains for whatever shitty product you have delivered for them?
Be it a web service that runs on 1980 servers with still the same stack (cough cough itunesconnect, membercenter, bug tracker, etc etc etc etc) incompatible with vast majority of modern browsers around (google at least sticks a "beta" close to it for a few years, it could work for a few decades for you);
be it your historical incapacity to build web UI;
be it the complete lack of any resemblance of valid documentation and lets not even mention manuals (oh you say that the "status" variable is "the status of the object"? no shit sherlock, thank you and no, a wwdc video is not a manual, i don't wanna hear 3 hours of bullshit to know that stupid workaround to a stupid uikit api you designed) for any API you have developed;
be it the predatory tactics on smaller companies (yeah its capitalism baby, whatever) and bending 90 degrees with giants like Amazon;
be it the closeness (christ, even your bugtracker is closed and we had to come up with openradar to share problems that you would anyway ignore for decades);
be it a desktop ui api that is so old and unmaintained and so shitty, but so shitty, that you made that cancer of electron a de facto standard for mainstream software on macos;
be it a IDE that i am disgusted to even name, xcrap, that has literally millions of complains for the same millions of issues you dont even care to answer to or even less try to justify;
be it that you dont disclose your long term plans and then pretend us to production-test and workaround-fix your shitty non-production ready useless new OS features;
be it that a nervous breakdown on a stupid little guy on the other side of the planet that happens to have paid to you dozens of thousands of euros (in mandatory licences and hardware) to actually let you take an indecent cut out of his revenues cos there is no other choice in a monopoly regime, matter zero to you;
Assuming all of these and much more:
How can you sleep at night with all the screams of the devs you are exploiting whispering in you mind? Are all the money your earn worth?
** As someone already told you elsewhere, HAVE SOME FUCKING PRIDE, shitty people AND WRITE THE FUCKING DOCS AND FIX THE FUCKING BUGS you lazy motherfuckers, your are paid more than 99.99% of people on earth, move your fucking greasy little fingers on that fucking keyboard. **
PT2: why the fuck did you remove the ESC key from your shitty keyboards you fuckshits? is it cos autocomplete is slower than me searching the correct name of a function on stackoverflow and hence ESC key is useless? at least your hardware colleagues had the decency of admitting their error and rolling back some of the uncountable "questionable "hardware design choices (cough cough ...magic mouse... cough golden charging cables not compatible with your own devices.. cough )?12 -
In the 90s most people had touched grass, but few touched a computer.

In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.
The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.
Whats left after filtering, is strictly the primes.
I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.
I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).
Well, imagine my surprise when I had zero false positives.
Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.
My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.
I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.
I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.
The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.
If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.16 -
Meetings.
Too many meetings.
"Why do you explain...." 10kv electrical shock.
Explanation so everyone has the same knowledge.
"But CD ES process of LCE..." Water. From the emergency hose. In the face.
For fucks sake, we are using speech in a meeting so stop using motherfucking abbreviations you shit hole.
"We had bugs". Taking an hot iron and shoving it somewhere nice.
Explain - what the fuck are you talking about? What bugs? Tickets? Documentation? Implications of the bugs? Hate. Much hate.
Um. I don't know. Maybe. But if.
Thumb wrenches.
Please, stop wasting time, if it's non important, a " No " doesn't hurt....

Okay then, ex-android user there.
It started with Xperia TX - it was flagship Sony phone back then. It blew my mind when I touched it for the first time. You know, exploring android for the first time in my life was amazing.
It ran just well for about a year. Then it started to fall apart. I need to clarify that I kept it non-rooted, full stock. I'm not into that customization things.
At first, I noticed significant lags. They were everywhere. The longer I used smartphone, the more lags I encountered. I did factory reset, but lags haven't gone anywhere.
Year 2. Front camera stopped working. Battery became unreliable as fuck, going down to 40% and then instantly to zero. What?
Year 3. Camera broke. It refused to start, just giving me "Camera is not available" error.
I tried factory reset again. It helped at first, but month have passed and all that issues came back. And it also became sluggish as fuck.
Got Meizu m3s year ago. The exact same story. Long story short, in one year I got this:
1. Black spots on every picture I take. Much likely a matrix issue.
2. Camera also became slow as fuck, requiring about 10 seconds to even start.
3. Vertical stripes all along the screen. I never dropped my phone, it just appeared once and became brighter and brighter every day I used the phone.
4. Two huge yellow spots on screen. I think it happened because phone's cpu heat up the screen and it broke.
But the most important thing is that fucking lags chased me in every app, they were everywhere. Fucking tiny-ass lags. And they're not going anywhere, they're become more and more significant with time.
Don't say me about oneplus, samsungs and other top android phones. They are conceptually the same, the only different thing is hardware.
That's why I switched. IPhone has its downsides, but it's silky smooth. And my friend's iPhone 4 (not s) feels just as smooth as my brand new se.
I'm not going to jailbreak it. I don't need customizing the hell out of it.
I just needed quick and reliable phone, and SE seems to be exactly what I wanted.
Peace to android folks tho✌️17 -
never before have I been happy to be asked to work overtime, but for once, fuck yeah...
Bit of back story, I am tech lead on a massive project that has been run like a complete shit show, the PM who also happens to be the brains behind the project seems to think we are miracle workers and for the first 9/10 months of the project would make significant, like delete a weeks worth of code and start over changes, 3-5 times per week. There are features for the v1 release that have been built in excess of 5 times. I have been saying since October that even without all his constant changes, we will NOT make the deadline, and naturally as is part of my job I argued against every unnecessary feature he tried to implement, eventually he pulled me into a meeting to tell me how much he values my opinion, I need to stop arguing with him and he does not want to work with yes men (I have a rant about that convo already).
I believe our CEO finally started smelling a rat as he insisted on joining our daily stand-ups, during which said PM scripted some lovely stories to disguise the fuckup we are in, and since has assigned another PM to take over and do proper project management and risk analysis.
That is where the email comes in, a lot of the work assigned to me will miss the deadline by a month, honestly I am impressed that it is by so little and so few people will not be missing it, but anyway, he probably spun a few stories there too.
So I spent part of the work compiling the most perfect surgical response as not not actively throw him under the bu, but create a quite a few questions that they hopefully as, as himself and the CEO where cc'd into the mail.
And the jist is, the deadline itself was still impossible and 8 of the 10 tasks assigned to be have ZERO back-end whatsoever, and those tasks are about 80/90% integration to said non-existent back-end, some of those services and data structures have not even been planned yet and we are a week past the deadline and 3 weeks from the just as useless extension. -
Managed to derive an inverse to karatsuba's multiplication method, converting it into a factorization technique.
Offers a really elegant reason for why non-trivial semiprimes (square free products) are square free.
For a demonstration of karatsubas method, check out:
https://getpocket.com/explore/item/...
Now for the reverse, like I said something elegant emerges.
So we can start by taking the largest digit in our product. Lets say our product is 697.
We find all the digits that produce 6 when summed, along with their order.
thats (1,5), (5,1), (2,4), (4,2), and (3,3)
That means for one of our factors, its largest digit can ONLY be 1, 5, 2, 4, or 3.
Lets take karatsubas method at step f (in the link) and reverse it. Instead of subtracting, we're adding.
If we assume (3,3)
Then we take our middle digit of our product p, in this case the middle digit of 697. is 9, and we munge it with 3.
Then we add our remaining 3, and our remaining unit digit, to get 3+39+7 = 49.
Now, because karatsuba's method ONLY deals with multiplication in single digits, we only need to consider *at most* two digit products.
And interestingly, the only factors of 49 are 7.
49 is a square!
And the only sums that produce 7, are (2,5), (5,2), (3,4), and (4,3)
These would be the possible digits of the factors of 697 if we initially chose (3,3) as our starting point for calculating karatsubas inverse f step.
But you see, 25 can't be a factor of p=697, because 25 is a square, and ends in a 5, so its clearly not prime. 52 can't be either because it ends in 2, likewise 34 ending in 4.
Only 43 could be our possible factor of p.
And we *only* get one factor because our starting point has two of the same digit. Which would mean p would have to equal 43 (a prime) or 1. And because p DOESNT (it equals 697), we can therefore say (3,3) is the wrong starting point, as are ALL starting points that share only one digit, or end in a square.
Ergo we can say the products of non-squares, are specifically non-prime precisely because if they *were* prime, their only factors would HAVE to be themselves, and 1.
For an even BETTER explanation go try karatsuba's method with any prime as the first factor, and 1 as the second factor (just multiply the tens column by zero). And you can see why the inverse, where you might try a starting point that has two matching digits (like 3,3), would obviously fail, because the values it produces could only have two factors; some prime thats not our product, or the value one, which is also not our product.
It's elegant almost to the level of a tautology. -
Just an advice:
Keep in mind that you can now have ES modules in nodejs with the esm package. And it's a zero config install.
For those that don't know, in js ES modules is the import/export syntax and is a huge upgrade from cjs (the require syntax) because you find out "pre runtime" when a specific import is non existent.1 -
I’m not suicidal. But It’s scary how much I envy people I know who recently died. They have zero problems. No need to look for a job, like I have to right now. No sense of fear or anxiety about screwing up relationships. No worry about health or wealth or any of that. Just done. Like I said, I’m not suicidal. Too scared to hurt myself and too afraid that on the other side I would regret it (yes, i happen to actually know it’s not just blackness and non-existence). But if I got hit by a bus tomorrow, I wouldn’t complain.11

markdown is not good enough! the tools aren't there for non-devs and there's no concordance on moving forward *compatibly* for anything other than headers and __possibly__ lists.
md has been around for years and still no consensus on comments, meta data, css, data imports, etc.
i could never in good faith recommend to a non-dev to use markdown, even though every academic and professional writer from legal to journalism should exclusively be using markdown to write and store their documents. the data portability and ease of search, retrieval, collection, distribution, etc of markdown compared to pdf or docx is enormous. markdown is the hex format of text, the perfect layer of data and visual so that the user and the computer can both operate on text as blocks of data rather than weirdly styled paragraphs that need to be reformatted BY HAND for citation-style or journal format, or paper size. FOR EACH SUBMISSION. Academics literally rewrite their 100-page papers to accommodate up to 10 different submission requirements.
They could be clicking MLA vs Chicago and/or using a journal's stylesheet to recompile for its styles.
Today there is some support from zotero et al to take away some of the pain, but it makes ZERO SENSE for writers to have to keep and store and keep up to date, multiple versions of the same document. Git pull does not exist for them. But the worst part is that git isnt the solution to their problem. They need a compiler more than they need version control. But they also desperately need vcs. They ALL literally have a million files named "dumdum.dumFINAL-3084_lastversion \2020, this one.dum".
They dont have git or anything like it, because they need a line-by-line solution like markdown for git to become effective.
All of writing is basically mired in the fact that people cant even roll up their paragraphs and see what the fuck it is theyre saying. Most writing reads like a long scroll through some nonsense that goes nowhere. Like this rant. but the point is that markdown and line-by line editing actually produces more logically sound writing. You start to think in terms of defining ideas in blocks, ... like code.9 -
More and more, I am getting frustrated/depressed from the attitude of our customers who complain, moan and get angry about issues in their infrastructure, while at the same time, refusing to pay more so the issues could be mitigated.
Like, a client's angry with us today for having one of their non-production-critical databases inaccessible for... Hmm... About 8 hours now (So a whole workday).
Like... I get it, some of your employees couldn't work with it offline, but like... What the hell do we do? You keep data from as far back as several years ago in there, without partitioning, without exports, in a mix of innodb and myisam, so when the DB crashes, and its replication has to be reset from zero, reimporting all the data takes hours upon hours, and importing .sql files just takes time.
Or another client who got angry when their app fell out of the internet, cuz one of their myisam-based log tables crashed, and had to be repaired, with data spanning several years back, meaning it took hours to fix...
The more I work with these "basic" and "simple" infrastructure designs that is *not* redundant, or HA, the more I wonder -- How do the big names out there do it? How do you design systems with fault tolerance so a single DB table crash doesn't lead to the whole app getting inaccessible?
We have... One, exactly one, client, who uses MariaDB with Gallera, and that cluster is *amazing*, it just keeps chugging along, without a care in the world. But it cost them quite a lot, as they had to buy 3 DB servers, instead of 1...1 -
Was working in an n-tier website, standard Web forms, BAL, DAL, database architecture. Validation and processing of data done in the BAL. Not the best idea, but whatever. Well apparently some developer thought it was too much work to pass his data through the BAL, so he directly accessed the DAL, performing zero validation on the data being passed in. Luckily, this was in a non-critical part of the site but the PM at the time nearly had a heart attack when I told him.

Is privacy really that big a deal some of the more tin-foil hats make it out to be? Look at Estonia, their government knows every last detail about an individual citizens life. Result: they are basically in a golden age as everything is efficient as there is zero red tape. This is what technology can achieve if we don’t bog ourselves down with non-issues1

Is there an Android media player that doesn't take over headset buttons, doesn't store a history, doesn't search for media to play, and doesn't do shit when off when you accidentally hit your headset button?
Is the headset button thing just an Android 11 problem?
I use vlc for the desktop and it does exactly what I want. On Android it takes over headset buttons and plays last file even after being completely shutdown and history is disabled. I HATE apps that do shit without you telling them to. The only way to fix this in vlc is to clear its cache and history manually in its settings and then forcing it to restart the app. Another thing vlc did was have full screen controls when I swiped right when the phone was fucking locked! I cannot remember what I did to disable that, but that was not cool at all. I think that was some fucked up android 11 feature.
I tried MX Player and it has zero options for disabling history.
So I figured I would ask here. Are there any non-shitty media players for Android?
I am so close to saying fuck you android 11 and sending the damn phone back. I hate the automatic shit I have to figure out how to turn off every time I do something. Leave me the fuck alone until I tell you to do something you pos phone.8 -

Sorry for the non-dev question, but does anyone know of any good emulators for PS4?
Help me plis, I wanna play horizon: zero dawn
