Yet another commercial seminar upset I won't give up a day of my time to fly to the UK to speak at the event for no payment or reimbursement for my travel.

But of course I should think about the exposure and networking opportunities! 😕

Really makes you think.

Lamer rant

For a really long time I said to myself that this is too basic to rant about but lately it became so frequent and extreme that here is my rant about completely clueless users that ask me IT related questions.

Disclaimer: Said users are people that I generally can't avoid. Distant family members, neighbors and etc.

Case 0:
U: I don't know what's happening!! The computer doesn't work!!
M: What do you mean?
U: There's no Facebook! And everything is stuck and no messenger!!!
M: The WiFi on your laptop was off. I turned it on. Still, this doesn't mean that the pc wasn't working.
U: I don't understand this shit!!!

Case 1:
U: I hate this computer!!! It never works!!! Help meeee!!!
M: What now?
U: Where did the internet disappear?!
M: (assuming it's wifi or browser related)
Actually user moved the Chrome window to bottom-right corner and lost it.

Every time I try to show the user how I resolve the issue the user yells that there are too many steps, that they are complicated and that I'm a bad teacher and doing it too fast.

Case 2:
U: My computer is so slow! It barely can load google translate! And I can't listen to music on youtube!! Shitty laptop! It's you! Your computers in the apartment drain everything!!!
M: You have no idea what you are talking about.
U: My husband told me that your computers are heavy and drain everything!
M: What exactly did he tell you that my devices drain?
U: I don't know! All the energy! I believe him! He knows!
M: My computers drain less electricity than your vacuum and I have a separate internet connection. Not only we share nothing but also I drain nothing.
U: Since you appeared all the computers are slow!!!!

Fkk...

Case 3:
U: I don't understand, where is my whatsapp?
M: You can't locate the app on your phone?
U: Yes! F*ck, help me! I'm so angry and I really need this NOW!!!
M: Shut up. I'm already here and helping.
(I open users phone and whatsapp is the active app...)
U: I can' t find my whatsapp with Clara!

F*ck you! F*ck you! Ghckjfshij!!!

Case 4:
(crazy hitting on my door)
U: I don't have THE internet!!!
It's you again! You took all of THE internet!!!
M: No, it doesn't work like that. Your provider is bad, your package is cheap and your cables are of low quality.
U: I need THE internet immediately!!! Stop playing with your typing and fix the facebook or I'll cut the power cables to the house!!

I can go on, just don't think that recalling all those events is healthy for me.

Biggest scaling challenge I've faced?

Around 2006~2007 the business was in double-digit growth thanks to the eCommerce boom and we were struggling to keep up with the demand.

Upper IT management being more hardware focused and always threw more hardware at the problem. At its worst, we had over 25 web servers (back then, those physical tall-rectangle boxes..no rack system yet) and corresponding SQL server for each (replicated from our main sql server)

Then business boomed again and projected the need for 40 servers (20 web servers, 20 sql servers) over the next 5 years. Hardware+software costs (they were going to have to tear down a wall in order to expand the server room) were going to be in the $$ millions.

Even though we were making money, the folks spending it didn't seem to care, but I knew this trajectory was not sustainable, so I started utilizing (this was 2007) WCF services and Microsoft's caching framework Velocity. Started out small, product lookup data (description, price, the simple stuff) and within a month, I was able to demonstrate the web site could scale with less than half of our current hardware infrastructure.

After many political battles (I've ranted about a few of those), the $$ won and even with the current load, we were able to scale back to 5 web servers and 2 sql servers. When the business increased in the double-digits again, and again...we were still the same hardware for almost 5 years. We only had to add another service server when the international side of the business started taking off.

Challenge wasn't the scaling issue, the challenge was dealing with individuals who resisted change.

Had a meeting with my boss earlier. Got yelled at for:
a) Working on a high-priority, externally-committed ticket (digit separators) that i was 85% done with on the Friday afternoon before my vacation instead of jumping to a lower-priority screwdriver ticket that just came in. Even though my boss agreed with me that what I did was exactly what I should have done, it's still bad because I was apparently rude to product by not doing as they asked?
b) Taking too long on that digit separator ticket that amounts to following a gigantic mess of convoluted spaghetti and making a few small changes, and making sure it doesn't break the world because it's all so fucking convoluted and fragile as hell. Let's not even mention my 4-10 hours of mandatory useless meetings every week.
c) Missing something that wasn't even listed in that same ticket -- somehow my fault? -- so I very obviously didn't test my work. Even though specs all passed and QA also tested and signed off on it as working and complete. Clearly half-assed and untested. Product keeps promising/planning UATs and then skipping them, and then has the audacity to complain about it.
d) Not recovering fast enough from burnout and daily mental breakdowns. I can still barely get out of bed and you want me to be super productive? Got it. Guess what? I'm being amazingly productive for my mental health. But my boss, Mr. Happy-go-lucky, thinks depression is dropping your icecream cone on your clean kitchen table, and this three-ton pile of spaghetti is "maybe a little messy, I guess."

So I need to somehow "regain the confidence" of both him and product because I'm taking awhile on difficult tickets (surprise), while having these ridiculous breakdowns (surprise), and because I don't fix things that aren't even listed in the fucking tickets (fucking surprise) -- and worse, that the lack of information is somehow entirely. my. fault. (surprise fucking surprise)

GOD I HATE THESE PEOPLE.

!!pointless story

Bug report comes in from a coworker. "Cloudinary uploads aren't working. I can't sign up new customers."

"I'll look into it" I say.

I go to one of our sites, and lo! No Cloudinary image loads. Well that can't be good.

I check out mobile app -- our only customer-facing platform. None of the images load! Multiple "Oops!" snackbars from 500 errors on every screen / after every action.

"None of our Cloudinary images load, even in the mobile app," I report.

Nobody seems to notice, but they're probably busy.

I go to log into the Cloudinary site, and realize I don't have the credentials.

"What are the Cloudinary credentials, @ceo?" I ask.

I'm met with more silence. I use this opportunity to look through the logs, try different URLs/transforms directly. Oddly, everything seems fine except on our site.

I check Slack again, and see nothing's changed, so I set about trying to guess the credentials.

Let's see... the ceo is basically illiterate when it come to tech, so it's probably not his email. It's a startup, and custom emails for things cost money, and haven't been a thing here forever, so it's probably oen of the CTO's email aliases. he likes dots and full names so that narrows it down. Now for the password.... his are always crappy (so they're "easy to remember") and usually have the abbreviated company name in them. He also likes adding numbers, generally two-digit numbers, and has a thing for 7s and 9s. Mix in some caps, spaces, order...

Took me a few minutes, but I managed to figured it out.

"Nevermind, I guessed them." I reported.

After getting into Cloudinary, I couldn't find anything amiss. Everything looked great. No outage warnings, metrics looked fine, images all loaded. Ex-cto didn't revoke payment or cancel the account.

I checked our app; everything started loading -- albeit slowly.

I checked the aforementioned site; after a few minutes, everything loaded there, too.

Not sure what else to do, and with everything appearing to work, I said "Fixed!" and closed the issue.

About 20 minutes later, the original person said "thanks" -- never did hear anything from the ceo. I've heard him chatting away in the other room the entire time.

Regardless, good thing for crappy passwords, eh?

some miserable life...

I swear to god, I'm going to track down the dipshit who just made my day hilariously painful.

So here I am, finishing up this project that's been going on for what feels like an eternity, when I get an email "why doesn't order X show up in this other system?".

I mean, it's a common thing they can take 15 minutes to push across, so the usual quick glance and what do you know, it's just sitting there as if it's waiting to be pushed through, than an hour later... it's still there, so I start digging, maybe a data issue, nope looks all good, customer details, payment details, products...

just another order, jump on the logs and all looks fi......... wait.... why does this postcode have 3 digits and not 4 , Australia has 4 digit postal codes fyi, looks at order again, 3 digits, look at log, 3....hold on why's it only 3 digits, checks code, handled as string... ok..... where the fuck would it drop a digit.... frontend requires 4 digits, validation requires 4 digits... how the fuck did you get 3 digits in... I can't see anything anywhere that logically makes sense for this🤔

Drops address into google and it's a postcode starting with 0.

Jumps on DB and the fucker is an int in the postcode table. For all you playing at home 0123 <> 123

I don't know if I should feel bad, or impressed, it's been 7 years since this table was created, and 7 years before someone managed to live in one of these parts of the country with a leading 0.

QA didn't spot this years ago,
No one tested this exact scenario,
The damn thing isn't even documented as a required delivery area, but here we are!

Kudos good sir, you broke it! 🤜 🤛
You sir may get your order now!

STORY TIME

Last year in College, I had two simultaneous projects. Both were semester long projects. One was for a database class an another was for a software engineering class.

As you can guess, the focus of the projects was very different. Databases we made some desktop networked chat application with a user login system and what not in Java. SE we made an app store with an approval system and admin panels and ratings and reviews and all that jazz in Meteor.js.

The DB project we had 4 total people and one of them was someone we'll call Frank. Frank was also in my SE project group. Frank disappeared for several weeks. Not in class, didn't contact us, and at one point the professors didn't know much either. As soon as we noticed it would be an issue, we talked to the professors. Just keeping them in the loop will save you a lot of trouble down the road. I'm assuming there was some medical or family emergency because the professors were very understanding with him once he started coming back to class and they had a chance to talk.

Lesson 1: If you have that guy that doesn't show up or communicate, don't be a jerk to them and communicate with your professor. Also, don't stop trying to contact the rogue partner. Maybe they'll come around sometime.

It sucked to lose 25% of our team for a project, but Frank appreciated that we didn't totally ignore him and throw him under the bus to the point that the last day of class he came up to me and said, "hey, open your book bag and bring it next to mine." He then threw a LARGE bottle of booze in there as a thank you.

Lesson 2: Treat humans as humans. Things go wrong and understanding that will get you a lot farther with people than trying to make them feel terrible about something that may have been out of their control.

Our DB project went really well. We got an A, we demoed, it worked, it was cool. The biggest problem is I was the only person that had taken a networking class so I ended up doing a large portion of the work. I wish I had taken other people's skills into account when we were deciding on a project. Especially because the only requirement was that it needed to have a minimum of 5 tables and we had to use some SQL language (aka, we couldn't use no-SQL).

The SE project had Frank and a music major who wanted to minor in CS (and then 3 other regular CS students aside from me). This assignment was make an app store using any technology you want. But, you had to use agile sprints. So we had weekly meetings with the "customer" (the TA), who would change requirements on us to keep us on our toes and tell us what they wanted done as a priority for the next meeting. Seriously, just like real life. It was so much fun trying to stay ahead of that.

So we met up and tried to decided what to use. One kid said Java because we all had it for school. The big issue is trying to make a Java web app is a pain in the ass. Seriously, there are so many better things to use. Other teams decided to use Django because they all wanted to learn Python. I suggested why not use something with a nice package system to minimize duplicating work that had already been done and tested by someone. Kid 1 didn't like that because he said in the real world you have to make your own software and not use packages. Little did he know that I had worked in SE for a few years already and knew damn well that every good project has code from somewhere else that has already solved a problem you're facing. We went with Java the first week. It failed miserably. Nobody could get the server set up on their computers. Using VCS with it required you to keep the repo outside of the where you wrote code and copy and paste changes in there. It was just a huge flop so everyone else voted to change.

Lesson 3: Be flexible. Be open to learning new things. Don't be afraid to try something new. It'll make you a better developer in the long run.

So we ended up using Meteor. Why? We all figured we could pick up javascript super easy.Two of us already knew it. And the real time thing would make for some cool effects when an app got a approved or a comment was made. We got to work and the one kid was still pissed. I just checked the repo and the only thing he committed was fixing the spelling of on word in the readme.

We sat down one day and worked for 4 straight hours. We finished the whole project in that time. While other teams were figuring out how to layout their homepage, we had a working user system and admin page and everything. Our TA was trying to throw us for loops by asking for crazy things and we still came through. We had tests that ran along side the application as you used it. It was friggin cool.

Lesson 4: If possible, pick the right tool for the job. Not the tool you know. Everything in CS has a purpose. If you use it for its purpose, you will save days off of a project.

sync meeting:
dev: damn, the tests failed again

bossman: let's blame it on the neutrinos hitting the mainframe which flips a digit and causing the tests to fail this time!

dev: ok ...!

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.

When I learnt programming, sugar was still made out of salt and hence not used in coffee.

Also, we didn't have source level debuggers, only the "print" method. However, compiling was also slow. It was faster and more convenient to go through the program and execute the statements in one's head. This helped understanding what code is doing just by reading it. It also kept people from trial and error programming, something that some people fall for when they resort to single step debugging in order to understand what their own code is even doing.

Compiling was slow because computers in general were slow, like single digit MHz. That enforced programming efficient code. It's also why we learnt about big Oh notation already at school. Starting with manual resource management helped to get a feeling for what's going on under the hood.

So here's the story about a big Fuck up by a TRAI chief in India

He posted an open challenge on twitter:
"Here's my 12 digit Aadhar card (social security no for Indians) number. Show me if you can do any harm to me. "

And Twitter obliged, a French hacker aliased @fs0c131y (Elliot Alderson) took the challenge and he started posting his phone number, email, and other personal stuff on twitter.

Still the official thinks he's safe and no harm has been done to him! He openly says, "Even if you get my bank account no what can you do?"

So here I am, skrewing around with the Google Authenticator app and the dodgiest base32 code generator I've ever built and generating a 56 char unique ID, and a 8 digit time based code.

WTF, all these products, services and logins that use 6 digit codes... and this fucking thing can handle 8 without breaking 😑

Now... to hook it into a QR code class... and spit out an image I can actually scan, without calling google charts api.

I can't say I've written one of those before 🙃

Just got a lection from my manager.
Today he sent me an email with request to change validation on one field validation from decimal(5,3) to int which will be 5 digit number. Ok i did that, I changed it on UI, changed validation, changed mappings, changed dtos, created migration files, and changed it in databse. After i did all of that I replied to his email and said that ive changed validation and adjusted it in database.

After my email here comes rage mail from manager with every fuckin important person in cc I kid you not. Manager is asking why the fuck did I change database when Ive could only use different validaton for that field on UI.

I Almost flipped fuckin table. What does validation good do if you wouldnt be able ti save that form? And form has like 150 fields. And if I left validation only everthing would fuckin break.

Sometimes i think that its better not to think.

I went to the tech department at my school to get some solder and a few offcuts of wire, but some generous person gave me 6 raspberry pi's that he didn't need anymore! But that's not all, he also gave me 5 rangefinder sensors, 4 motors, a 4 digit 7segment display, a couple of sd cards, a few other various sensors, and some wires
Oh, and I got my solder, too :)

I’m trying to add digit separators to a few amount fields. There’s actually three tickets to do this in various places, and I’m working on the last of them.

I had a nightmare debugging session earlier where literally everything would 404 unless I navigated through the site in a very roundabout way. I never did figure out the cause, but I found a viable workaround. Basically: the house doesn’t exist if you use the front door, but it’s fine if you go through the garden gate, around the back, and crawl in through the side window. After hours of debugging I eventually discovered that if I unlocked the front door with a different key, everything was fine… but nobody else has this problem?

Whatever.
Onto the problem at hand!

I’m trying to add digit separators to some values. I found a way to navigate to the page in question (more difficult than it sounds), and … I don’t know what view is rendering the page. Or what controller. Or how it generates its text.

The URL is encrypted, so I get no clues there. (Which was lead dev’s solution to having scrapeable IDs instead of just, you know, fixing them). The encryption also happens in middleware, so it’s a nightmare to work through. And it’s by the lead dev, so the code is fucking atrocious.

The view… could be one of many, and I don’t even know where they are. Or what layout. Or what partials go into building it.

All of the text on the page are “resources” — think named translations that support plus nested macros. I don’t know their names, and the bits of text I can search for are used fucking everywhere. “Confirmation number” (the most unique of them) turns up 79 matches. “Fee” showed up in 8310 places before my editor gave up looking. Really.

The table displaying the data, which is what I actually care about, isn’t built in JS or markup, but is likely a resource that goes through heavy processing. It gets generated in a controller somewhere (I don’t know the resource name so I can’t find it), and passed through several layers of “dynamic form” abstraction, eventually turned into markup, and rendered as a partial template. At least, that’s how it worked in the previous ticket. I found a resource that looks right, and there’s only the one. I found the nested macros it uses for the amount and total, and added the separators there… only to find that it doesn’t work.

Fucking dead end.

And i have absolutely nothing else to go on.

Page title? “Show”
URL? /~LiolV8N8KrIgaozEgLv93s…
Text? All from macros with unknown names. Can’t really search for it without considerable effort.
Table? Doesn’t work.
Text in the table? doesn’t turn up anything new.
Legal agreement? There are multiple, used in many places, generates them dynamically via (of course) resources, and even looking through the method usages, doesn’t narrow it down very much.

Just.
What the fuck?
Why does this need to be so fucking complicated?

And what genius decided “$100000.00” doesn’t need separators? Right, the lot of them because separators aren’t used ANYWHERE but in code I authored. Like, really? This is fintech. You’d think they would be ubiquitous.

And the sheer amount of abstraction?
Stupid stupid stupid stupid stupid.

Cracking old recovery CDs for the 9x/2000/XP era shines some light into how companies operated and when concepts came to be in that time:

Packard Bell: An EXE checks that you're running on a Packard Bell machine and reboots if it's not. How do we bypass it? Easy: just fucking delete it. The files to reinstall Windows from scratch come from...
...
C:?
Yup. Turns out Packard Bell was doing the recovery partition thing all the way back to the 9x era, maybe even further. Files aren't even on the restore disc so if your partition table got fucked (pretty common because malware and disk corruption) you were totally fucked and needed to repurchase Windows. (My dad, at the time, only charged at-cost OEM prices for a replacement retail copy. He knew it was dumb so he never sold PB machines.)

Compaq:
Computer check? Nope, remove one line from a BATCH file and it's gone.

Six archives, named "WINA.ZIP" through "WINF.ZIP" (plus one or two extras for OEM software) hold Windows. Problematic? Well... only because they never put the password anywhere so the installer can't install them. (Some interesting on-disc technician-only utils, though!)

Dell:
If not a Dell machine, lock up. Cause? CONFIG.SYS driver masquerading as OAK (the common CD driver) doing the check, then chainloading the real OAK driver. Simple fix: replace the fake driver with the real one.

Issues?

Would I mention this one if there weren't?

Disc is mounted on N:. Subdirectories work, but doing anything in them (a DIR, trying to execute something, trying to view shit in EDIT.COM) kicked you back to the disc root.

Installer couldn't find machine manifest in the MAP folder (it wanted your PC's serial before it'd let you install, to make sure you have the correct recovery disc) so it asked for 12-digit alphanumeric serial. The defined serials in the manifest were something like "02884902-01" or similar (8-2, all numbers) and it couldn't read the file so it couldn't show the right format, nor check for the right type.

Bypassing that issue, trying to do the ACTUAL install process caused nothing to happen... as all BATCHes for install think the CD should be on X:.

Welp.

well that was fun. Now to test on-real-PC behavior, as VBOX and VMWare both don't like the special hardware shit it tries to use. (Why does a textmode GUI need GPU acceleration, COMPAQ?????)

I followed a tutorial on how to use TensorFlow to create digit recognition. It worked. Theres just a few issues ...

I found the code on a website, and wrote what i saw (almost copy paste)

I barely understood any of the code

I did not understand the results

I have no idea where the images was found

Im almost more confused now, than when i started, thats not good xD

TL;DR - Girlfriend wanted to learn coding, I might have scared her off.

Today, my girlfriend said she wants to learn coding.
Me: why?
She: well, all these data science lectures are recommending Python and R.
Me: Ok. But, are you interested in coding?
She: No, but I think I have to learn.
Me: Hmm.. coding requires a clear thought process, and we should tell the computer exactly what needs to be done.
She: I think I can do that.
Me: Okay... then tell the computer to think and give a random number between 1 to 10.
She: I will use that randint function. (She has basic knowledge in C)
Me: Nope. You write your own logic to make the computer think.
She: What do you mean?
Me: If I were you... Since it is just a single digit number.. I would capture the current time and would send the last digit of milliseconds @current time.
She: Oh yeah, that's cool. Understood! I will try...

We both work in same office.. so, we meet up for lunch

I didn't ask about it, but she started,
She: Hmm, I thought about it, but I was not able to think of any solution. May be its not my cup of tea.

I felt bad for scaring her off... :(

Anyway, what are some other simple methods to generate random numbers like OTPs. I am interested in simple logics, which you have thought of..not the Genius algorithms we have in predefined libraries.

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.

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.

10 year anniversary 'celebration' for a couple of employees (one dev, one a DBA) and the VP of the department was saying kind words about them, talking about the 'good old days'.

VP to the DBA: "I apologize, when you started, you walked into my database architecture. I didn't know that much back then and never thought about the architecture much beyond a few years. Its amazing my design has lasted over 20 years and triple digit business growth..blah blah blah"

Inner voice: "Mother F-er!...My database was designed IN SPITE of your meddling and demanding to create 1,500 field tables. Shut the F up you egotistical bastard!"

I can't even count how many times I had to stop him from, for example, adding a 'ProductID' field to a Customer table.

Me: "Why did you add a product id field?"
VP: "How else will we know what product the customer wants to buy?"
Me: "You mean like a wish list? What if the customer wants more than one product?"
VP: "Oh, that’s easy, we'll create more fields when that happens. ProductID2. Microsoft made it really easy to add fields."
Me: "We already have a wish list table schema. Customer can have as many wish lists and as many products as they want."
VP: "I don't understand. All I want is a field for me to store the product I'm buying. I don't know why you make this so hard, its just one more field."

Now the VP is bragging all the success was due to his expertise?! Gaaaaahhhh!

I quelled my rage with ample quantities of donuts, juice, and chocolate milk.

I just want to share a small win in my career. finally, I got a 6-digit salary (relative to my country's currency)

the down side though, it's a .NET position

So today I arrived on Ireland to hike for three weeks. Tomorrow I'm heading out together with one single other scout to walk 160 km from point A to point B, both of which are unknown until the minute we start. I'm not quite sure how much internet coverage I'll have, so perhaps there won't be so much ranting, commenting and ++'ing. Sad to leave for almost a month with just a couple of hundred ++'s left to reach the magic 5 digit score. Well, anyways. Unless I appear earlier, have a nice few weeks!

Dear intellectual crew, your double-digit IQ little shitposter needs your help.

The situation in Russia is always bad and it will always become worse and worse. In addition to that, it's illegal to have medications that can potentially cure me. Add 15 sunny days a year in my city and it becomes clear that I need to leave.

However, despite the absolute lack of sunny days, I FUCKING LOVE my city, Saint-Petersburg. When I was living in Moscow for like six months, I liked Moscow but I was missing my city every single day. Sometimes I forgot that I'm not in St. Petersburg anymore, tried to figure out what street I'm on, realized that I'm in Moscow and felt like I'm physically suffocating. I always miss my city so bad.

I'm not going to talk about why do I love it so much. If I ever start, I'm going to write a book about it.

Questions are:
1. Is it Stockholm syndrome? I don't miss Russia and don't identify myself as Russian. I only miss one city and I wasn't even born here.
2. How do I leave in that mental state?

This is the only problem that is holding me. Money, finding a place to stay and finding a job I can approach rationally, but my problem I can not.

Little anecdote from my in-house it:

"Our passwords are safe because we change them every 3 months and they have to contain uppercases, lowercases, numbers and special characters. 6 digit length is enough and can't be hacked."

As you can see from the screenshot, its working.
The system is actually learning the associations between the digit sequence of semiprime hidden variables and known variables.

Training loss and value loss are super high at the moment and I'm using an absurdly small training set (10k sequence pairs). I'm running on the assumption that there is a very strong correlation between the structures (and that it isn't just all ephemeral).

This initial run is just to see if training an machine learning model is a viable approach.

Won't know for a while. Training loss could get very low (thats a good thing, indicating actual learning), only for it to spike later on, and if it does, I won't know if the sample size is too small, or if I need to do more training, or if the problem is actually intractable.

If or when that happens I'll experiment with different configurations like batch sizes, and more epochs, as well as upping the training set incrementally.

Either case, once the initial model is trained, I need to test it on samples never seen before (products I want to factor) and see if it generates some or all of the digits needed for rapid factorization.

Even partial digits would be a success here.
And I expect to create multiple training sets for each semiprime product and its unknown internal variables versus deriable known variables. The intersections of the sets, and what digits they have in common might be the best shot available for factorizing very large numbers in this approach.

Regardless, once I see that the model works at the small scale, the next step will be to increase the scope of the training data, and begin building out the distributed training platform so I can cut down the training time on a larger model.

I also want to train on random products of very large primes, just for variety and see what happens with that. But everything appears to be working. Working way better than I expected.

The model is running and learning to factorize primes from the set of identities I've been exploring for the last three fucking years.

Feels like things are paying off finally.

Will post updates specifically to this rant as they come. Probably once a day.

This day I have received the most glorious news in e-pistolary form. For some years, I was suffering in support of a client who was, well, insufferable. My presence there paralleled the divine comedy in both essence and fact.

I opened the missive, expecting another plea to bail them out of whatever clusterfuck they found themselves in. Instead, what I found was something truly magical.

"Hey Human,

I hope this finds you well. I'm not sure if you remember a few years back, we were trying to decide between IBM Cloud and AWS. Well, after years of battling FF*, we're finally moving ahead with AWS. He failed one too many times to deliver anything visibly. After you left, there was no one left he could use to steal credit, ideas, and work.

FF is still pushing to have them use IBM cloud as a "warm backup" in the event "AWS fails." We will see where that goes.

I figured you'd like to know; you were the void in the wilderness for a long time. I don't want to think about how much time we could have saved if we had just listened.

PeeEm**"

This event represents a personal victory, albeit belated, over a few peoples' absurd amount of privilege. Towards the end, I was vicious about my contestation to the insanity of adopting a desperate hedge attempt-as-cloud offering from a failing company. Some examples:

// cloud 'strategy meeting'
Moi: What cloud platform are we looking at using?
FF: We're looking at IBM cloud and AWS as a second.
Moi: Why is that? I understand you're obligated to rep your offering first, but that decision doesn't seem to have the customer's best interest at heart.
FF: IBM cloud is a market leader; AWS isn't as good.
Moi: I see. I mean, that's the tech equivalent of the company's fleet management considering monkeys on tricycles as a strong competitor to service trucks, but I get what you mean.

// steering meeting
Director: Who can we look to as an example? Who is currently using the IBM cloud?
Moi: No one; they account for a single-digit portion of the actual cloud market. Their long game to sell you a "Hybrid Cloud," which means put some front end payload in a CDN, and buy n-frame units of IBM z servers for the DC with IBM gateway appliances acting as connective tissue. So it's not the cloud at all, really.
Director: How does it compare in cost?
Moi: It's generally 40% more expensive than other clouds, and it only goes higher as you option their software.
Director: What about Watson? I hear Watson is good?
Moi: It's a brand name. Most of the "Watson" product is just a facade on top of FOSS products like Spark, Hadoop, Elasticsearch, etc.
Director: Those were words. They sounded good. FF say it's good tho so we'll believe him because we're from the same city.
Moi: *deletes Director from LinkedIn*

Moral of the story: Never trust a vendor that only recommends their products.

*FF = FatFuck - an embarrassingly rotund individual whose girth is roughly equivalent to his height. He shit his way into an IBM architect position in his mid-20s purely due to winning the visa lottery. He had fake hair glued to his head for his wedding to hide his male pattern baldness; his arrange-married wife undoubtedly cries herself to sleep after sex.

Unpaid internships are the worst thing. You exploit young people and promise them experience. Seriously business makes tons of money yet they come with ways to exploit a young person in IT. I think it is evil.

When someone tries to generate getters and setters in C# as if it was Java, you may think: "He is starting!"... And then you ask: "How long have you been working with C#?"

Surprising answer: "1 year" 😱

What have you been doing till now?

I've got at least 4 hours of homework... Now THIS bullshit!!

A story about burnout you say? Well, here it goes.

In 2019, I worked in a now-defunct startup. Back then, I was deep in "treatment" with wrong medications that almost ended up turning me into a vegetable. When I was hired, my mind was already deteriorating quickly, and I was caught in a downward spiral of losing intelligence.

Prior to working there, there was never ever ever a situation in my career when I was given a problem to solve and failed to do it.

But right then, with already double-digit IQ and constant, pumping anxiety, I was seeing task descriptions that looked familiar and doable, yet I absolutely could not do them. I couldn't comprehend. It was an absolutely screeching, crippling panic about me losing my intelligence forever, being fired and ending up unhireable, dying alone on the streets.

Apart from my depression I recovered from, this very experience was a trauma that haunts me to this day, every day. You know, my experience being raped as an adolescent doesn't, but this, it's something else. Now, my intelligence is back, I design architecture, I'm a CTO, and my solutions are objectively cleaner and better in every way than what I did pre-depression. Yet, I still feel a sharp, sudden rush of anxiety, and my heart skips a beat, when I think about writing code or even opening the IDE.

I don't know how does one recover from this. I'm now slowly transitioning into "architecting CTO" role that is just being a devrel, assessing ethics, working with business to realize their need, designing solutions and leaving the implementation for the team to do. You know, the stuff I was taught in the uni.

Maybe doing open source and launching small pet projects will help. But at this stage of my life I have no emotional resource to care.

Customer requested the implementation of a "Master PIN" Code for accessing their appliances, to be used by field technicians when the users forgot their PIN.
Actually they could also read or reset it via USB using the config utility, but then again it's much more convenient not having to carry a laptop all the time...

Our only contact person at that company - the guy we got all the requirements from, let's call him Mr. L - wouldn't talk only positive about the company and managers, but we never worried as the project was making good progress.

In the final phase of the project, Mr. L was often hard to reach, always seemed to be busy even when we just needed a prototype approved to start production.
He always claimed to be waiting for approval from his supervisors and engineers, still discussing minor things with them.

When he left the company about three months later, it turned out he was pretty much the only person knowing about the details of the project, and his successor would start asking us very basic questions about the appliance,
wondering why we had implemented certain things the way they were.
(Well, how about we implemented everything just as requested by a former co-worker of yours?!)

Somewhere in the preliminary specs previously exchanged with Mr. L, there is even a hint of a "Master PIN", but the value is never specified anywhere on paper.

Today, we are not sure if anyone except for him even knew about it.
Maybe we should ask them whether they are now selling a product that has a 4-digit backdoor PIN nobody at the company is aware of?

Obviously, it is the birth year of Mr. L.

Another day, another time exporting svgs from Figma, sizing them, and exporting them to png into our app as the developer.

But no, I get it, what designers do is extremely taxing on the brain and any additional steps must be excruciating! Let me do anything that requires even the lowest of double-digit IQ! After all, I'm your local resident full stack clown™️!

Motherfucking stupid windows 10.

Wanted to try out cortana with all features after disabling it via regedit.
So naturally I created a Microsoft account and linked my user to it. Of course I used a random password generator and saved it in a passwort vault.
Then an update happened, I restarted my computer and guess what this stupid piece of SHIT garbage software did?
It prompted me to enter my password. Not the password I had for my local user BUT THE MOTHERFUCKING 15-DIGIT RANDOM PASSWORT GENERATED AND NOT EVEN VIEWED ONCE FUCKING SHIT!!!
Did they even ask if I wanted that? No they fucking didn't. Did they WARN ME? NO. NO THEY FUCKING DIDN'T.

That's the last straw. I'll kick windows down the garbage bin where it belongs and programm my own AI with open source software.

Still on the primenumbers bender.
Had this idea that if there were subtle correlations between a sufficiently large set of identities and the digits of a prime number, the best way to find it would be to automate the search.

And thats just what I did.

I started with trace matrices.
I actually didn't expect much of it. I was hoping I'd at least get lucky with a few chance coincidences.

My first tests failed miserably. Eight percent here, 10% there. "I might as well just pick a number out of a hat!" I thought.

I scaled it way back and asked if it was possible to predict *just* the first digit of either of the prime factors.

That also failed. Prediction rates were low still. Like 0.08-0.15.

So I automated *that*.

After a couple days of on-and-off again semi-automated searching I stumbled on it.

[1144, 827, 326, 1184, -1, -1, -1, -1]

That little sequence is a series of identities representing different values derived from a randomly generated product.

Each slots into a trace matrice. The results of which predict the first digit of one of our factors, with a 83.2% accuracy even after 10k runs, and rising higher with the number of trials.

It's not much, but I was kind of proud of it.

I'm pushing for finding 90%+ now.

Some improvements include using a different sort of operation to generate results. Or logging all results and finding the digit within each result thats *most* likely to predict our targets, across all results. (right now I just take the digit in the ones column, which works but is an arbitrary decision on my part).

Theres also the fact that it's trivial to correctly guess the digit 25% of the time, simply by guessing 1, 3, 7, or 9, because all primes, except for 2, end in one of these four.

I have also yet to find a trace with a specific bias for predicting either the smaller of two unique factors *or* the larger. But I haven't really looked for one either.

I still need to write a generate that takes specific traces, and lets me mutate some of the values, to push them towards certain 'fitness' levels.
This would be useful not just for very high predictions, but to find traces with very *low* predictions.

Why? Because it would actually allow for the *elimination* of possible digits, much like sudoku, from a given place value in a predicted factor.

I don't know if any of this will even end up working past the first digit. But splitting the odds, between the two unique factors of a prime product, and getting 40+% chance of guessing correctly, isn't too bad I think for a total amateur.

Far cry from a couple years ago claiming I broke prime factorization. People still haven't forgiven me for that, lol.

Automation always fascinated me. Not only it looks and behaves like a life form, it also can perform billions of calculations without making a single mistake while I can’t even multiply double-digit numbers with my double-digit IQ.

If you pick the right components, you can make an immortal, perfect machine that can do its job for centuries, even millennia without a single mistake. There is nothing else on earth that can do this.

There is a robot surgeon and its hands never shake. It’s just flawless. If it fucks up, there is only you to blame, the flawed, pathetic operator.

And now it’s time to remember that it was just a 40s technology all along. And now it’s time to remember that now there is machine learning. A whole new perspective isn’t it. All the mistakes that machines make are sitting in front of the monitors.

No wonder I decided to be an engineer.

Why? 😪

Some sign-up forms be like

"Enter any 11-digit prime number to continue"

So note to self, when creating random IDs, maybe generating 1,000 digit long IDs constantly is the source of that massive ram spike and subsequent crash...

Coolest project I worked on was the one that let me learn to code.

It was a mobile calculator for the blind. The app counted the user's taps to come up with the number they wanted, instead of having them hover their finger around the screen to find each digit. Then each operation was mapped to a swipe gesture.

That awkward moment when you phone IKEA Costumer Service to ask for the buCode that is used in their API to see product status in stores.

First I spoke to a salesperson and almost had to explain what an API is. The next person understood (after a while) that it is a 3-digit code that identifies the store.

And yes, I am from Sweden. 😂

Saw one of my colleague tryna sign in into Microsoft, where it was asking for 7 digit passcode but the system was sending him 6 digit passcode. LMAO. just windows things.

So at the beginning of the year I took a new job at a large, stable company. Leaving a failing startup, toxic leadership, and an absolutely stellar development team in the process. Given what's happened in the world since then, I'm overall pretty happy with the decision to have some more stability for me and my family.

That being said, I'm super bummed out (and weirdly burned out) now because I feel like I'm becoming a worse engineer.

I've worked for large organizations before (single digit thousands of employees), but never have I experienced a personification of enterprise memes like this. Leadership too out of touch, lots of bullshit work just to make worthless reports look good, horrific legacy codebases and infrastructure, you name it.

My biggest problem are the expectations are shockingly low. I went from a hyper demanding work environment where the fate of the entire company seemed to hang in the balance each and every week, to an environment where we literally invent arbitrary, bullshit deadlines and requirements so we have something to feel some stress about. And even still, most of the deadlines are laughably far away. The pace of work that's not only accepted, but praised is so slow that I find myself procrastinating more and more. I spend so little time doing any work, and even less time doing things that would pass as "interesting", that I feel like the engineering and problem solving part of my brain is starting to rot.

To make matters worse, the culture is weirdly confrontational despite the pace being so slow. The people here are _incredibly_ pedantic and will launch into 15 minute arguments over the tiniest incorrect details in a story title. Interrupting someone just so you can say what they were going to say is a daily trial. And most ridiculous of all, _repeating_ word for word what someone _just_ finished saying like it was your thought and you didn't even hear them. I don't even know what the motivation for this could be because it makes them look like total clowns.

I've tried to bring up some of the things I find ridiculous, but most everyone has just accepted them at this point and there's virtually no effort to try and make things better. I only get stupid non-answers like "obviously you've never worked at a large enterprise before". Yes I have. Twice. We didn't partake in half the bullshit that happens here.

Honestly this was all just a passing frustration for the first month or two, but 7 months in I'm starting to see myself become complacent. My current output would be absolutely _shameful_ to myself from a year ago, and even my personality has started to shift to the point that I just go with the flow and don't challenge anything.

I've stopped keeping up with tech trends. I've stopped experimenting with new things. I've tried to do more work on personal projects, but the burnout is starting to affect my life outside of work. In general I've just completely stopped trying, and I absolutely fucking hate it.

I also feel like a total tool for complaining about having a cushy, stable job where I barely have to do anything given the current world climate. But I'm more miserable now than I think I've every been in my career. Has anyone else experienced this and found ways to combat it? How do you get your motivation back once it's lost and there isn't even any pressure to regain it?

I totally blame myself for becoming part of this joke. That's totally on me for not continuing to push myself, but I never realized how much of my "drive" from the last job was coming from the high stakes we were operating under. I really just want to get back to being proud of my work and pushing to be better.

Anyway, sorry for the lengthy post. This turned out to be a weirder rant/self-roast than I intended. But I'm hoping this will be the first step to kicking my own ass back into shape.

Care to help me with some some-what basic math?

100 characters exist in the ASCII codec.

I'm trying to figure out the minimum amount of characters required to encode them. (= Turning each digit into a two digit char set that doesn't mach any other char set to enable me to do other things with them. i.e: A = dE)

It would simply be: x^2, where x is the number of minimum characters required.. But I don't know how to interact that with 100 to find x.

Guyz let hack this
Here is the tea

A house wife forgot her bank 'ATM PIN' which is a four digit number, but luckily she remembered some hints on how to recall this 'PIN'
Here are some of the clues
(1) The 1st digit is half of the 2nd
(2) The sum of the 2nd and 3rd is 10
(3) The 4th is equal to the 2nd plus 1
(4) The sum of all the digits is 23

What is the ATM PIN ?

I took a job with a software company to manage their product, which was a SaaS property maintenance system for real estate, social housing, etc.

There was no charge to real estate agents to use it but maintenance contractors had to use credits to take a job, which they pre-purchased. They recharged their credit costs back to the real estate agent on their invoice).

Whether this pricing model is good or not, that's what it was. So, in I came, and one of the first things management wanted me to deal with was a long-standing problem where nobody in the company ever considered a contractor's credits could go into the negative. That is, they bought some credits once, then kept taking jobs (and getting the real estate agent to pay for the credits), and went into negative credits, never paying another cent to this software company.

So, I worked with product and sales and finance and the developers to create a series of stories to help get contractors' back into positive credits with some incentives, and most certainly preventing anyone getting negative again.

The code was all tested, all was good, and this was the whole sprint. We released it ...

... and then suddenly real estate agents were complaining reminders to inspect properties were being missed and all sorts of other date-related events were screwed up.

I couldn't understand how this happened. I spoke with the software manager and he said he added a couple of other pieces of code into the release.

In particular, the year prior someone complained a date on a report was too squished and suggested a two-digit year be used. Some atrocious software developer worked on it who, quite seriously, didn't simply change the formatting of that one report. No, he modified the code everywhere to literally store two-digit years in the database. This code sat unreleased for a year and then .... for no perceivable reason, the moron software manager decided he'd throw it into this sprint without telling me or anybody else, or without it being tested.

I told him to rollback but he said he'd already had developers fixing the problems as they came up. He seemed to be confident they'd sort it out soon.

Yet, as the day went on more and more issues arose. I spoke to him with the rest of the management team and said we need to revert the code but he said they couldn't because they hadn't been making pull requests that were exclusive to specific tickets but instead contained lots of work all in one. He didn't think they could detangle it and said the only way to fix was "play whack-a-mole" when issues came up.

I only stayed in that company for three months; there was simply way too much shit to fix and to this day I still have no idea the reasoning that went on in the head of anyone involved with that piece of code.

At work we have to split a potentially large ID into 2 10-digit long parts that will be passed to an outside system that will later return them with some more data to us.

A colleague had implemented it using regular expression, it passed code review, everything was ok, until he noticed a potential problem. For some cases, because the outside system stores them as int and therefore will remove any leading zeros, there will be no way to reconstruct the number.
So we brainstorm and I propose ether a modified regex, or to just use math like part1 = id % 10^10 and part2 = floor(id % 10^10) and then we can reconstruct it simply by: part2 * 10000000000 + part1

Colleague: - Well, the regex will be faster, there won't be any calculations
Me: - :| I disagree but ok..

We do some more brainstorming and testing and find a case where the proposed new regex fails as well
So I bring up my previous proposal, I explain what exactly it does.

Colleague: - I don't like the math, it has calculations, which won't be needed before we reach the 11th digit

Have I missed some major development in computer hardware? When did they become bad/slow at doing math? :|

1000

Shit I missed my first 1000, shh
I totally posted this exactly at
1000, nobody saw anything!

So if I calculated that correctly
it will JUST take me 18 more
months for the next digit . .

(((╹д╹;)))

I just had such a forfilling moment.

Normally, i often (force myself) go to bed at night, after i worked on a project of mine, with these thought saying "oh man i wanted to get that feature done today" or "i want to finish this and that part of my code".I am sure everyone of you knows the feeling, when your brain communicates that you are just not done for today.

Today it was different. I got a project of mine working in it's first state, where i put much heart, love and time in.Just a few minutes before i finished for today i got my server responding the expected numbers(some kind of pin-code). It's a very easy system: Someone(at the time only me and my debug mode :3) on a android phone request a verification which is checked and processed by the server. The server creates a random six-digit number, returns it encoded to the client and sends an email to the user, which currently sends it in plain text(shame on me).
Yeah, the user enters the number and voilà
And of course, all the Pincodes can only be used once.
I got to bed with this feeling of luck and succes.

I hope tomorrow is going to be a productive day!

I am so lucky right now.

Have a good day everyone!

My (junior) colleague gives me an existential crisis as he builds a fabric.js clone from scratch up in very little time.

Then he tells me he forgot his 4 digit bank pin he's be using for 7 years.

I've just bought 3 months sky ticket...
THEY ONLY ALLOW A 4-DIGIT NUMBERS ONLY "PASSWORD"?!?!

IN WHAT YEAR DO THEY LIVE???

AND THEY EVEN SEND IT TO YOU VIA EMAIL ALONGSIDE YOU USERNAME!

I guess their old windows server which handles their authentication would be overcharged when it'd handle real passwords.

I have 9 voicemails on my work phone. We have to change our six+ digit PIN every month, so I'm just going to not check my voicemails.

Fucking hours counting systems.
One of the hardest part of consulting job is to put hours into fucking table.

One of those solutions is so smart that when I make mistake I need to call manager to unlock the input.
My friend from work compared it to playing saper.

Some of those systems work only in IE.
Some of those run java inside browser.
Some I need to be in company domain others I need to logout from company domain.

I see the amazing articles about those amazing software solutions, still opening IE and running java to put digit into text input or pick number from select.
Fucking nightmare.

Hey fellas, especially you security nerds.

I've had asymmetric encryption explained to me a number of times but I can't get a handle on it because no example actually talks in human terms. They always say "two enormous prime numbers", which I understand, but I can't conceptualize.

Can someone walk me through an entire process, showing your math & work, using some very small, single- or double-digit primes? Such as if I were to encrypt the text "hello world" using prime numbers like 3, 5, and 7

When you spend 1 hour trying to solve a programming challange... And then realise "All integers starting with 1" means all integers from 1 to inf, and not all integers that begin with the digit 1. UUUGGH

Just realized every 3 digit ++ amount can be translated to a shorthand hex code. Maybe this should change the background for new users until they reach 1000 ++s? Just throwing it out there, not really requesting it as a feature. 800++ would be maroon as an example.

I have about a week of holidays left before my classes start and I'm thinking about creating a notepad with password protection and cloud sync so it can be accesed on other devices.

So this is how it will work.
Probably the same interface as windows notepad so no one notices. It can be used to write a personal diary or anything that you don't want other people to know. It will ask for a 4 digit code when you open it(at first you'll see some text, you'll just enter you pin after that text and without pressing enter if you pin is write you'll see the text changes to your previously saved text and if your pin is wrong no error will be displayed itll work as a normal text editor for intruders and probably this wrong pin will be sent to you on you emil with other info). Now even if yoy minimize the window you'll have enter the pin again or even your windows gets out of focus. So you can have it open all the with out worrying.

I'll be using C# for this which I have no experience with. But I'll get it so no problem here.

Provide your feedback on this with some suggestions.

*Sorry I didn't post it on calebs section because I don't have $10.

Installed JDK 8 patch 111 in preparation for an upgrade to our application servers . The app installer requires patch 45 or above. Come to find out the app installer can only deal with a 2 digit patch number. Uninstalled JDK 8 patch 111 to install patch 92 only to find that patch 92 installer won't work because patch 111 has messed with the registry and didn't do a thorough cleanup during the uninstall.

Learning to play Go (came only close to single digit kyu) now table tennis.

Is it just me or is the 'storefront' test for CAPTCHA much harder than the schoolbus or traffic light? Could be my diminishing eyesight, or bourbon too.

After examining my model and code closer, albeit as rudimentary as it is, I'm now pretty certain I didnt fuck up the encoder, which means the system is in fact learning the training sequence pairs, which means it SHOULD be able to actually factor semiprimes.

And looking at this, it means I fucked up the decoder and I have a good idea how. So the next step is to fix that.

I'm also fairly certain, using a random forest approach, namely multiple models trained on other variables derived from the semiprimes, I can extend the method, and lower loss to the point where I can factor 400 digit numbers instead of 20 digit numbers.

Bootcamps get you up and running in coding quickly. If you are a programmer, companies are only interested on how quickly, error free and cheaply you produce marketable output. Bootcamps enable this.

More or less you are not more than a former assembly line worker putting parts on a car platform. Your value is not very high as you may be exchanged at any time at their will.

Nevertheless, you can earn money quickly. You trade in your youth and time which might be a dead end in the long-term. Trends go to machine learning, artificial intelligence. They will not need Bootcamp people and code workers.

It is better you set up Bootcamps and sell them versus absolving this. Like selling shovels during the gold rush, but not working in the mud of Alaska by yourself.

Your choice is: Making quick money, which fades anyway; or striving for the long-term future proof career.

C/S degrees from Technical Universities of reputation give to you the right direction under a strategic consideration. Companies which pay well, or freelancing with a solid acknowledged background, will always look for top graduates. People from Bootcamps are just OK for hammering assembly line coding. Even worse with SCRUM in one noisy room under enormous team server pressure controls, counting your lines of code per minute, with pale people all around. And groups of controllers never acknowledging nor trusting your work.

To acquire a serious degree, a Bachelor is nothing. Here, in INDIA, Bachelor now is what a former high school grade was. You must carry a diploma or Masters degree combined with internships at big companies with high brand recognition. This will require 4–6 years of your lifetime. You can support this financially by working part-time freelancing as making some projects front- or back-end web, data analysis and else.

Bootcamp people will lose in the long-term. They are the modern cannon fudder of software production.

It is your choice. Personally, I would never do Bootcamps. Quality and sustainability require time, deep studies and devotion.

So first rant, here goes weirdness, and also lengthy rant

So in my company we have the hr and accounting managed by the same person which also deals with all things employee related and she had a need for a way to extract a birthday from, what is in our country the personal identification number, things go great i get a formula that performs parts of the magic up to the point where the first digit of the number dictates the gender and century to be used when forming the full year, mind you only the last two digits of the year are in plain within the id number so i thy a number of ideas. After bashing around google sheets for a while ( i've got open office installed and formulas don't export well to the excel that person uses but google sheets does so i built it there).

First idea : make a few conditionals to check for the value so we have 1 and 2 for 19th century, 3 and 4 for 18th century , 5 and 6 for 20th so i go ahead and write my conditions and they fail, all evaluates to false, it cascades through the else variants up to the last one so i'm wondering if the "if" itself doesn't support the or operator, seems it does, next i think it's the bloody condition written wrong so i reevaluate my logic in php in a test script, it works as intended, then i think ok not the right function called, let's see the docs, docs confirm i'm doing it right but what was wrong was the way i was getting that first number, using left seems to produce a string although the base thing is a number, now i start searching how i can cast it, like you would normaly do when the data type is fried, value function appears to be the solution but it isn't working....now i'm thinking "ok so i have a value and different things to print out so let's look for a switch, maybe it can understand that" switch function found under the form of choice, i get it sorted but am stuck wondering why the heck was the if and value combination not working.

Simple answer to that : value doesn't work well with function results, a known bug listed by someone in a comment, a comment i have failed to read for about 45 minutes of trying to understand.

All in all it worked well for the person asking for it so it's nice.

After waiting for almost a month, yesterday I went to check on how my computer was doing, since I hadn't got any messages or calls ever since.
I go to the store and ask one of the workers about how my laptop is doing, and that I'd left it there almost a month ago and that they'd tell me when it was time to get the papers and then the laptop itself. The girl asks me for my phone number and then my name, and found nothing on the computer. She goes somewhere inside the store and comes back with a colleague, who tells me that I need a process paper. I pull out the receipt the technician photocopied and signed because that was the only thing I had. I hadn't touched that part of my paste for the whole time after I left the computer there and I was 100% sure I didn't have the process paper with me until he started pressing me for it. I kept repeating that the technician told me that they'd call or message me when said process paper was ready, which I hadn't got any of those to go pick it up. The guy asks me if that were the number and name I'd given the tech guy and I said yes. Both of them disappear into the store again. They come back with a cardboard box and say that the surname written there was wrong by a char (as I've said before my name is unusual, and my surname is also unusual where I'm studying, but where I'm from there's like 5 or 6 families with that surname), so that's why they couldn't find it in the computer. After that they went through all the details I gave on the time of handing the PC and the number they told me was there was off by miles. I think I may have said a wrong digit but that number was way off. There should be some person who got calls or messages about a computer they don't even own LoL
They told me to try it and see if it was running OK and that I had 15d to go back if something was wrong
When I got home I turned it on, afraid it would start dying on me again LoL
I pass the login screen and the fan just starts working really hard and I'm worried. The ASUS guys reinstalled Win8 and the CPU is running wild already, going at about 3,5 GHz (2,5 max) and over 30% usage on nothing
After some minor inconveniences (making the USB with Win10 took longer than expected) I finally installed Win10 and the CPU usage drops to < 10% and runs at way below the 2,5 GHz max. It constantly uses <= 10-15% CPU and the fan makes no noise unless I put in a heavier game (like Oxygen Not Included - it asks for 4GB RAM minimum 8I), in which case it goes up a bit and runs at around 3 GHz, but it doesn't make as much noise as before, thank jesus. I'm gonna keep trying to see how it does and hope I don't have to go back to the store after the next 15d 8I
I can finally work and not be a leech on my friends because my old toshiba - which I forgot I'd brought with me to uni - is really old and it makes a lot of noise (the fan is constantly working too much but it's so old I don't bother anymore) and it heats my room a lot, so it's gonna be a nice change of pace HaHa

Why are more games or media platforms not encouraging the use of similar account naming conventions to Blizzards launcher or Discord.

The way you can have a name# with a 4 digit code pretty much gives you the ability to have 10k users with the same account name but still be unique.

Just tried PokeMMO which has been around since about 2010 I believe? Not only is their system shit with a 3 char limit and the inability to delete characters, but the game is so fucking old that I literally spent between 30-60 mins looking for a variation of my name that was both likable and available.

I've never designed a naming system like discords before, but surely its a better alternative to this shit?

This, thankfully, I didn't create myself. A shop I recently ordered something from had the worst username / password default combo.
After registration they gave you a default Password, your zip code. And your unchangeable username is your customer id, a five digit number which just increments for each new user. And because it is a shop which is only used by people of the same region there are maybe 10 different zip codes.

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.

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.

Got a phone call from a scammer claiming to be my Cell Phone Provider saying “Congratulations! You just recieved unlimited calls and messages for a year, now to win this please give the 4 digit pins given to you” then I recieved a 4 digit pin and warning label not to give this message to anyone else. I then noticed that this was a scammer, i got his probably fake number and I tried to mess with him by giving random codes, he then noticed that the numbers were fake in the 5 try.

I truly feel bad for this idiot and just call him a scammer and end the call...

So we used to build these awful "promotion" pages for a leading manufacturer in the area. Because the website was old as dirt, there was no CMS and everything was static html using Coldfusion for a few include files like for the nav and such.

Every year we would get a new project to tweak the promotion details a little, and change the year from 2011 to 2012, etc.

My predecessor put the digit "1" in an HTML file called year.html, then included it like:
"valid from January 1 though December 31, 201<cfinclude template="year.html">..."

Why? Just why? And if you're going to use include files, for Pete's sake at least use the proper .cfm file extension!

Never seen this one before...

Just came across a website that asks you an addition math problem to prevent bots. Except it's always adding two single digit numbers. And they are always 2 and 9...

My bandwidth is ordinarily a few hundred kbps, but whenever I torrent it can reach up to 2 mbps, while all other traffic from me and my housemates is stuck in the single digit kbps range.

What does BitTorrent do so fucking well, and how can other protocols replicate this success? Would the total available bandwidth be different if every protocol did whatever enables BitTorrent to summon bandwidth from thin air?

When I arrive 5 months ago to the company, I found that I'll have to work with an internee and someone that has a Masters degree, it is his first job and is in the company for more than a year and a half.
Me thinking, it's gonna be fine, but noooo, it's hell on earth!
What to do with someone like that and he does his work 5x slower and you have to repeat yourself 10 times because he forgets everything?
By the way, the 5x slower when I compare to the internee...

Nobody has any use from a 80% finished project (so not finished at all) except it was a lot of time and money to get to that point. Oh boy I need to make progress on about 500 different projects to get them to a useful stage.

Also very important lesson: Dont have your anxiety take over when facing the "omg I have a 6 digit number of things on my 2do list" because you can't say no to the "awesome" ideas you have.

Also: I have made a rule for myself that prevents me from starting/working on a side project when I have important deadlines on main projects

So I have an array of length 20 which stores a 64 bit decimal number by digits. The starting address is let's say array64. When I am trying to build up my number in ECX:EBX, I am using EDX as the iterator to access the individual elements of the array (I am loading them into AL)

.LOOP:
....
MOV AL, [array64+EDX]
INC EDX
....
JMP .LOOP

The problem is: somehow EDX cannot get higher than 10, so the program just stops and waits for input, when I try to work with a 12 digit number...
This module is outside the main function, and I thought about some Far Pointer problems, but all of my ideas just failed...

What is wrong here?

It should be possible to prove the collatz conjecture by mapping the unit digit transitions between numbers, namely into a finite state machine. From there we could use predicates and quanitifiers to prove, by process of exclusion, that for any given combination of 10s digit and 1s digit, no number can transition to anything but whats specified in the state machine assuming that number equals x in x3+1 or x/2

Ipso facto, a series of equations proving by process of elimination, that state machines transitions are the only allowable ones, would prove the collatz conjecture by proving the fsm is a valid representation for any given integer N.

I'm actually working on it now but I don't know enough about modular arithmetic and predicate logic to write a proof. I just have the state diagrams on some dot matrix paper at the moment.

If anyone wants to beat me to it, feel free.

So for example any number ending in 13, will, after x3+1, end in 40.

Any number ending in 40 will end in 20. Any number ending in 20 will end in 10, which will end in 5 as the unit digit.

It's easier to prove in the single digit case, and the finite state machine for that is already written, at least on paper.

I'll post pictures when I get a chance.

(a bit late for wk73 but I wanted to post this anyway)

Back in my first year of university, we had to write a relatively simple (though it looked super complicated back then) C++ console application. I don't know what it's called, but it's that game where the computer generates a random 4 digit code and you have to try to guess what it is. Every time you try, it will tell you which digits are correct, which would be correct if they were in a different position and which are outright wrong.

Anyway, the program had a main menu with a help option that would output a short guide on how to play the game. Instead of hard coding it into the source code, the "guide" had go be written in a separate text file and then read and dumped to the screen when necessary.

Here came my great idea on how to read files. Instead of looping through the file until I reached the end, I counted the number of lines my text file had and wrote some gem of a piece of code like this:

for (int i = 0; i<11; i++){
line = file.readline();
cout << line << endl;
}

My teacher obviously took points off for doing such a stupid thing, and I remember complaining A LOT about it. I argued that 11 was a constant because I didn't plan on changing the text file, and that the teacher had no right to take points off for only reading 11 lines because the file only had 11 lines, so it was read in full.

Goddammit, what an innocent little brat I was. I'm glad my first programming teachers were good enough to stay firm and teach me how to do things the right way, even if it's the hard way.

*looks drowsy* Ugh my head..

You know what, guys? If you can freshly and directly remember how to do this:

- calculate the time complexity for each type of loop and code structure

- knowing how to write the following regex:
"A 15-digit number starting with a possibility of a group of 1-2 digit numbers, segregated into three 5-digit numbers tuples with three different separator characters, evaluated ahead"

- mentally work out how to reverse an array's indexes (swapping algorithm) without writing anything down

- know how to optimize a binary search in your head

then kudos to you. lmao
I'm rusty. It took me a while..

Trained a hand digit recognition model on MNIST dataset.Got ~97℅ accuracy (wohoo!).Tried predicting my digits,its fucked up! Every ML model's story (?)

When logging in, why is there no reminder like 'your password was at least 8 characters long with at least one digit'.

A question for the community... What do the wk12 (replace 12 with two digit number) mean?

Today my teacher assigns a project before final exam. He says to think an idea for a site and realize it. Okay I think a vacation site and this is my problem, I want to build a search bar when a user digit a city and the system respons with a list of hotel and B&B in the city, but I don't know how tu build the bar o.O
Any ideas?

Ok... I am defeated I don't know what else to try...

Do you guys have any experience with ansible vault? I have my SSH password stored on a vault. It's referenced in my host file like this:
-----START SNIPPET-----
[LCL:vars]
ansible_ssh_pass='{default_pass}'

[LCL]
myhost ansible_user=my username
-----END SNIPPET-----

default_pass is stored as a yaml variable in passed.yml that I supply using --extra-vars '@passwd.yml'

When I enter my vault password I get an exception 'non hexadecimal digit found'.

The password is right for the vault, the vault file is in PWD .... I cannot find anything helpful.

Any ideas?

Idea: Make a programming language where arrays are indexed with py up to the nth digit.

And arrays start at 3.14

I got two files one called lte and the other called fcc2. The attached image is the fcc2 file. The first file is just a list of census blocks. 15 digit number per line on the lte file.I need help changing just the lines in the fcc2 file that have the same 15 digit number at the start of the line. Just need to change 2 variables in the line. FCC2 is a TSV file. any help would be appreciated.

I have double-digit IQ. I’m like Apollo 11 computer — 4kb RAM, but I’m a legend. You’re like a windows vista laptop — technically smarter but no one gives a fuck.

Brain fart.

In Java and many other languages there are basic types, like char and String. So why does Java have char and String, but not a digit type?

A number is basically a series of digits. For modular arithmetic it is very useful to be able to extract the 3 in the number 1234, it's just the 3rd digit in a number.

Base 2, base 10, base anything could be supported easily too. E.g. a base 2 digit would be:

digit d = 0b2; // or 1b2, but 2b2 would be a compilation error

A number would then be some kind of string of digits.

Any thoughts on this?

So anyone discover any good books written past 1990 which don't deal in hidden themes of your bs ? No elaborate color or number descriptions or dumbasses modifying jokes to two digit numbers that don't make sense ?

How to set 6 to 32 digit character and contain both letters and numbers

Looking for help starting with DevOps.

Does anyone know of a site or forum where you can talk about general coding/scripting patterns rather than just asking specific questions?

Bear with me, this may be a bit longer than most posts here.

I'm a self-taught admin/tech working with one colleague (who's also mostly self taught) at a high school, managing both clients and servers.
We've been doing most things manually bit I'm looking into converting as much work as possible into more of a DevOps setup, with Powershell-scripts for multi step tasks.
I want to do this for a number of reasons. Having a script doing a number of steps would cut down on time spent on individual tasks and minimize the risk that a step is missed or, perhaps even worse, mistyped. Also it's important that I actually learn what I'm doing, why something works and why something fails.

As and example, I have a powershell-script which moves a student from one year to another (basically they have user names with a two-digit prefix based on the year they started and a suffix with two letters from their first names and four from their last names) if they need to repeat a grade.
It basically renames the account in the AD with the correct year-prefix, changes the samAccountName, renames Home and Profile-directories on disk and changes paths on the profile-tab in AD, moves the user into a new OU and security group etc.
It works as intended if the user account to be renamed exists and there's no name conflict with the new name. But I'd like for the script to validate that there's no problem with user names, source and target security groups and OUs etc. and eventually split the script up into smaller clearly defined functions for better readability.
However, I don't want someone to just write the script for me, I'd prefer to be able to discuss script flow and come to my own conclusions and solutions.

Okay, so debian is just fucked by default then.

Created a Debian 10 persistence stick, and I'm having the fucking xorg issues ("No screens detected", xrandr says the same) i've had every fucking time i've installed debian, except a simple round of dpkg-reconfigure isn't fixing it this time.

Suggestions?

Things tried:

- dpkg-reconfigure <every package even remotely related>
- X -configure
- installing all firmware from linux-firmware repo
- reinstalling everything remotely related (with both reinstall and purge/install)
- Wayland ("failed to create compositor backend")
- creating my own xorg configs and driver-radeon configs and all that shit with my screen explicitly defined
- remaking the stick with a redownloaded ISO
- actually installing it to a HDD first
- crying in frustration
- different monitors
- someone else's machine (both AMD GPUs, mine's an R9 380, his an RX 3-digit something-or-other)
- an NVIDIA card (other tester threw his old 1080TI in his PC, set up all the drivers and shit, and nothing fucking changed)

what is this, Fedora?
