I have to let it out. It's been brewing for years now.
Why does MySQL still exist?
Really, WHY?!
It was lousy as hell 8 years ago, and since then it hasn't changed one bit. Why do people use it?
First off, it doesn't conform to standards, allowing you to aggregate without explicitly grouping, in which case you get god knows what type of shit in there, and then everybody asks why the numbers are so weird.
Second... it's $(CURRENT_YEAR) for fucks sake! This is the time of large data sets and complex requirements from those data sets. Just an hour through SO will show you dozens of poor people trying to do with MySQL what MySQL just can't do because it's stupid.
Recursion? 4 lines in any other large RDBMS, and tough luck in MySQL. So what next? Are you supposed to use Lemograph alongside MySQL just because you don't know that PostgreSQL is free and super fast?
Window functions to mix rows and do neat stuff? Naaah, who the hell needs that, right? Who needs to find the products ordered by the customer with the biggest order anyway? Oh you need that actually? Well you should write 3-4 queries, nest them in an incredibly fucked up way, summon a demon and feed it the first menstrual blood of your virgin daughter.
There used to be some excuses in the past "but but but, shared hosting only has MySQL". Which was wrong by the way. This was true only for big hosting names, and for people who didn't bother searching for alternatives. And now it's even better, since VPS and PaaS solutions are now available at prices lower than shared hosting, which give you better speed, performance and stability than shared hosting ever did.
"But but but Wordpress uses MySQL" - well then kill it! There are other platforms out there, that aren't just outrageously horrible on the inside and outside. Wordpress is crap, and work on it pays crap. Learn Laravel, Symfony, Zend, or even Drupal. You'll be able to create much more value than those shitty Wordpress sites that nobody ever visits or pay money on.
"But but but my client wants some static pages presented beside their online shop" - so why use Wordpress then? Static pages are static pages. Whip up a basic MVC set-up in literally any framework out there, avoid MySQL, include a basic ACL package for that framework, create a controller where you add a CKEditor to edit page content, and stick a nice template from themeforest for that page and be done with that shit! Save the mock-up for later use if you do that stuff often. Or if you're lazy to even do that, then take up Drupal.
But sure, this is going a bit over the scope. I actually don't care where you insert content for your few pages. It can be a JSON file for all I care. But if I catch you doing an e-commerce solution, or anything else than just text storage, on MySQL, I'll literally start re-assessing your ability to think rationally.11 -
Our website once had it’s config file (“old” .cgi app) open and available if you knew the file name. It was ‘obfuscated’ with the file name “Name of the cgi executable”.txt. So browsing, browsing.cgi, config file was browsing.txt.
After discovering the sql server admin password in plain text and reporting it to the VP, he called a meeting.
VP: “I have a report that you are storing the server admin password in plain text.”
WebMgr: “No, that is not correct.”
Me: “Um, yes it is, or we wouldn’t be here.”
WebMgr: “It’s not a network server administrator, it’s SQL Server’s SA account. Completely secure since that login has no access to the network.”
<VP looks over at me>
VP: “Oh..I was not told *that* detail.”
Me: “Um, that doesn’t matter, we shouldn’t have any login password in plain text, anywhere. Besides, the SA account has full access to the entire database. Someone could drop tables, get customer data, even access credit card data.”
WebMgr: “You are blowing all this out of proportion. There is no way anyone could do that.”
Me: “Uh, two weeks ago I discovered the catalog page was sending raw SQL from javascript. All anyone had to do was inject a semicolon and add whatever they wanted.”
WebMgr: “Who would do that? They would have to know a lot about our systems in order to do any real damage.”
VP: “Yes, it would have to be someone in our department looking to do some damage.”
<both the VP and WebMgr look at me>
Me: “Open your browser and search on SQL Injection.”
<VP searches on SQL Injection..few seconds pass>
VP: “Oh my, this is disturbing. I did not know SQL injection was such a problem. I want all SQL removed from javascript and passwords removed from the text files.”
WebMgr: “Our team is already removing the SQL, but our apps need to read the SQL server login and password from a config file. I don’t know why this is such a big deal. The file is read-only and protected by IIS. You can’t even read it from a browser.”
VP: “Well, if it’s secured, I suppose it is OK.”
Me: “Open your browser and navigate to … browse.txt”
VP: “Oh my, there it is.”
WebMgr: “You can only see it because your laptop had administrative privileges. Anyone outside our network cannot access the file.”
VP: “OK, that makes sense. As long as IIS is securing the file …”
Me: “No..no..no.. I can’t believe this. The screen shot I sent yesterday was from my home laptop showing the file is publicly available.”
WebMgr: “But you are probably an admin on the laptop.”
<couple of awkward seconds of silence…then the light comes on>
VP: “OK, I’m stopping this meeting. I want all admin users and passwords removed from the site by the end of the day.”
Took a little longer than a day, but after reviewing what the web team changed:
- They did remove the SQL Server SA account, but replaced it with another account with full admin privileges.
- Replaced the “App Name”.txt with centrally located config file at C:\Inetpub\wwwroot\config.txt (hard-coded in the app)
When I brought this up again with my manager..
Mgr: “Yea, I know, it sucks. WebMgr showed the VP the config file was not accessible by the web site and it wasn’t using the SA password. He was satisfied by that. Web site is looking to beat projections again by 15%, so WebMgr told the other VPs that another disruption from a developer could jeopardize the quarterly numbers. I’d keep my head down for a while.”8 -
A few weeks ago at infosec lab in college
Me: so I wrote the RSA code but it's in python I hope that's ok (prof usually gets butthurt if he feels students know something more than him)
Prof: yeah, that's fine. Is it working?
Me: yeah, *shows him the code and then runs it* here
Prof: why is it generating such big ciphertext?
Me: because I'm using big prime numbers...?
Prof: why are you using big prime numbers? I asked you to use 11, 13 or 17
Me: but that's when we're solving and calculating this manually, over here we can supply proper prime numbers...
Prof: no this is not good, it shouldn't create such big ciphertext
Me: *what in the shitting hell?* Ok....but the plaintext is also kinda big (plaintext:"this is a msg")
Prof: still, ciphertext shows more characters!
Me: *yeah no fucking shit, this isn't some mono/poly-alphabetic algorithm* ok...but I do not control the length of the ciphertext...? I only supply the prime numbers and this is what it gives me...? Also the code is working fine, i don't think there's any issue with the code but you can check it if there are any logic errors...
Prof: *stares at the screen like it just smacked his mom's ass* fine
Me: *FML*12 -
I’m so mad I’m fighting back anger tears. This is a long rant and I apologize but I’m so freaking mad.
So a few weeks ago I was asked by my lead staff person to do a data analysis project for the director of our dept. It was a pretty big project, spanning thousands of users. I was excited because I love this sort of thing and I really don’t have anything else to do. Well I don’t have access to the dataset, so I had to get it from my lead and he said he’d do it when he had a chance. Three days later he hadn’t given it to me yet. I approach him and he follows me to my desk, gives me his login and password to login to the secure freaking database, then has me clone it and put it on my computer.
So, I start working on it. It took me about six hours to clean the database, 2 to set up the parameters and plan of attack, and two or three to visualize the data. I realized about halfway through that my lead wasn’t sure about the parameters of the analysis, and I mentioned to him that the director had asked for more information than what he was having me do. He tells me he will speak with director.
So, our director is never there, so I give my lead about a week to speak with her, in the mean time I finish the project to the specifications that the director gave. I even included notes about information that I would need to make more accurate predictions, to draw conclusions, etc. It was really well documented.
Finally, exasperated, and with the project finished but just sitting on my computer for a week, I approached my director on a Saturday when I was working overtime. She confirmed that I needed to what she said in the project specs (duh), and also mentioned she needed a bigger data set than what I was working with if we had one. She told me to speak to my lead on Monday about this, but said that my work looked great.
Monday came and my lead wasn’t there so I spoke with my supervisor and she said that what I was using was the entire dataset, and that my work looked great and I could just send it off. So, at this point 2/3 of my bosses have seen the project, reviewed it, told me it was great, and confirmed that I was doing the right thing.
I sent it off to the director to disseminate to the appropriate people. Again, she looked at it and said it was great.
A week later (today) one of the people that the project was sent to approaches me and tells me that i did a great job and thank you so much for blah blah blah. She then asks me if the dataset I used included blahblah, and I said no, that I used what was given to me but that I’d be happy to go in and fix it if given the necessary data.
She tells me, “yeah the director was under the impression that these numbers were all about blahblah, so I think there was some kind of misunderstanding.” And then implied that I would not be the one fixing the mistake.
I’m being taken off of the project for two reasons: 1. it took to long to get the project out in the first place,
2. It didn’t even answer the questions that they needed answered.
I fucking told them in the notes and ALL THROUGH THE VISUALIZATIONS that I needed additional data to compare these things I’m so fucking mad. I’m so mad.15 -
What is a pointer?
A descriptive and ELI5 answer found on Reddit:
You have a house.
When you’re outside, and you want to go home, you don’t make another house right where you are, because it’s too big for you to carry around or take apart.
So you carry a piece of paper or store on your phone the address of your house. Now you always know exactly how to find your house so that you can go home.
The piece of paper or your phone is a variable.
The variable contains an address (a reference) to your house.
You can make a copy of this piece of paper and hand it out to your friends when you invite them over, instead of building each friend a copy of your house.
You can have an address book filled with pages, where each page is an address (i.e., an array of pointers). Each page you turn (each index you increment) goes to the directly next address-containing variable.
Now if you cut the address book in half along its height, and then attach the lower half behind the upper half, then you have a book with smaller pages but more pages.
You can store phone numbers in this, and even if it’s the same total size, you have double the number of pages and double the number of phone numbers (if you store one number on each page).
Now, since the pointers to home-addresses are different from pointers to phone-numbers, turning the page in an address book (increment pointer by 1) moves forward by one address.
But turning the page in the phone book (incrementing pointer by 1) leads you to the next phone number, even if you technically turned only “half a page”.
That’s how pointer arithmetic works.

You can believe or not but it’s just one of those stories. It’s long and crazy and it probably happened.
A few years ago I was interviewed by this big insurance company. They asked me on linkedin and were interested. They didn’t specify who they were so I didn’t specify who I am either.
After they revealed who they are I was just curious how they fuck they want to spend those billions of dollars they claimed in their press notes about this fucking digital transformation everyone is talking about. The numbers were big.
I got into 3 or 4 phone/skype interviews without technical questions and I was invited to see them by person.
I know that it would be funny because they didn’t asked me for CV so they didn’t know anything about me and I was just more curious how far I can get without revealing myself.
They canceled interview at midnight and I was in the middle of Louis de Funès comedies marathon so I didn’t sleep whole night. I assumed they would just reschedule but then they phoned me at 8 am if I can come because they made mistake.
So at first talk I was just interviewed by some manager I knowed after 5 minutes he would be shitty as fuck and demand stupid things in no time because he is not technical. He was trying to explain me that they got so great people and they do everything so fast.
From my experience speed and programming are not the things that match. ( for reference of my thought see three virtues of a GREAT programmer )
So I just pissed them off by asking what they would do with me when I finish this transformation thingy next year. ( Probably get rid off and fire at some point were my thoughts )
Then I got this technical interview on newest gold color MacBook pro - pair programming ( they were showing off how much money they have all the time ).
The person asked me to transform json and get some data in javascript .
Really that was the thing and I was so bored and tired that I just asked in what ES standard I can code.
The problem was despite he told me I can do anything and they are using newest standards ( yeah right ) the “for of” loop didn’t worked and he even didn’t know that syntax existed. So I explained him it’s the newest syntax pointing mozilla page and that he need to adjust his configuration. Because we didn’t have time for that I just did it using var an function by writing bunch of code.
When he was asking me if I want to write some tests probably because my code looked ugly as fuck ( I didn’t sleep for more then 24 hours at that point and wanted to live the building as fast as I can) I told I finished and there is no time for tests because it’s so simple and dumb task. The code worked.
After showing me how awesome their office is ( yeah please I work from home so I don’t care ) I got into the talk with VP of engineering and he was the only person who asked me where is my CV because he didn’t know what to talk about. I just laughed at him and told him that I got here just by talking how awesome I am so we can talk about whatever he wants.
After quick talk about 4 different problems where I introduced 4 different languages and bunch of libraries just because I can and I worked with those he was mine.
He told me about this awesome stack they’re building with kubernetes and micro services and the shitty future where they want to put IOT into peoples ass to sell them insurance and suddenly I got awake and started to want that job but behind that all awesomeness there was just .NET bridge with stack of mainframes running COBOL that they want to get rid off and move company to the cloud.
They needed mostly people who would dump code to different technology stack and get rid of old stack ( and probably those old people ) and I was bored again because I work more in r&d field where you sometimes need to think about something that don’t exist and be creative.
I asked him why it would take so much time so he explained me how they would do the transformation by consolidating bunch of companies and how much money they would make by probably firing people that don’t know about it to this day.
I didn’t met any person working permanently there but only consultants from corporations and people hired in some 3rd party company created by this mother company.
They didn’t responded with any decision after me wasting so much time and they asked me for interview for another position year after.
I just explained HR person how they treat people and I don’t want to work there for any money.
If You reached this point it is the end and if it was entertaining thank YOU I did my best.
Have a nice day.5 -
Whoever implemented the data import in Numbers on Mac needs to be lined up against a wall and shot with needles until they wish they were dead.
Why on all of gods unholy green and shitty earth would i want data i import (EVEN IN CSV FOR FUCK SAKE) to be delimited by an arbitrary text width? WHAT THE ACTUAL FUCK
WHY WHY why would I EVER want to delimit my carefully structured data by fucking text width instead of new line or comma? AAAAARRRHHH
And what fucking big brain genius made this the DEFAULT SETTING for imported text AND CSV FILES. IT STANDS FOR COMMA SEPARATED FILE YOU FUCK BOI MAYBE JUST MAYBE I WANT IT SEPARATED BY FUCKING COMMMMMMMAAAAASSSSSS9 -
Best carrier choice: leaving the old company I worked for...
TLDR version: I yelled at owner/director to shove it..got layed off the next day. Never regreted that day!! EVER!!
Long version: I was asked to implement storing of CC numbers (yes, the whole lot) & their matchig CVC numbers..plain text, no encription.. company didn't even fulfilled standards to store last four digits.. so I yelled at the 'big boss' that he is crazy and that I won't do it.. Next day, I got handed a letter that said they have to lay me off due to lack of work and that my position is redundant & no other workplace for me.. Never been happier in my life!!
I wanted to quit for some time, due to crazy stuff they asked me to implement & how!? & toxic personel. I was called Hitler (& am actually proud of this!!) cuz I was work oriented & didn't kiss mrs.Director's ass.. I wasn't slacking like the rest of them did, so of course, I was the bad guy..
Anyhow, fast forward 6 months, got the best job ever & am now here for 5yrs+.7 -
Why is innumeracy acceptable in our society?
It riles me where I see something like a current affairs or political show, (basic) stats are presented and someone says "I don't understand statistics, but [personal story follows]"
And when a person says they don't understand numbers there's laughter and nodding.
Imagine if I was on a panel and someone handed me a sheet of paper and I said that I can't read big words. Would hilarity ensue or would they assume I wasn't qualified to be commenting on *anything*?
People, if you are functionally innumerate, it's not funny. You have a 5th grade, at best, education. Be embarrassed and get help.10 -
I've caught the efficiency bug.
I recently started a minimum wage job to get my life back in order after a failed 2 year project (post mortem: next time bring more cash for a longer runway)
I've noticed this thing I do at every job, where I see inefficiency and I think "how can I use technology to automate myself out of this job?"
My first ever application was in C++ for college (a BASIC interpreter) and it's been so long I've since forgotten the language.
But after a while every language starts to look like every other language, and you start to wonder if maybe the reason you never seriously went anywhere as a programmer was because you never really were cut out for it.
Code monkey, sure. Programmer? Dunno, maybe I just suffer from imposter syndrome.
So a few years back I worked at a retail chain. Nothing as big as walmart, but they have well over 10k store locations. They had two IBM handscanners per store, old grungy ugly things, and one of these machines would inevitably be broken, lost or in need of upgrade/replacement about once a year, per location. District manager, who I hit it off with, and made a point of building report with, told me they were paying something like $1500 a piece.
After a programming dry spell, I picked up 'coding' with MIT app inventor. Built a 'mostly complete' inventory management app over the course of a month, and waited for the right time.
The day of a big store audit, (and the day before a multi-regional meeting), I made sure I was in-store at the same time as my district manager, so he could 'stumble upon' me working, scanning in and pricing items into the app.
Naturally he asked about it, and I had the numbers, the print outs, and the app itself to show him. He seemed impressed by what amounted to a code monkeys 'non-code' solution for a problem they had.
Long story short, he does what I expected, runs it by the other regionals and middle executives at the meeting, and six months later they had invested in a full blown in house app, cutting IBM out of the mix I presume.
From what I understand they now use the app throughout the entire store chain.
So if you work at IBM, sorry, that contract you lost for handscanners at 10k+ stores? Yeah that was my fault (and MIT app inventor).
They say software is 'eating the world' but it really goes to show, for a lot of 'almost coders' and 'code monkeys' half our problem is dealing with setup and platform boilerplate. I think in the future that a lot of jobs are either going to be created or destroyed thanks to better 'low code' solutions, and it seems to be a big potential future market.
In the mean while I've realized, while working on side projects, that maybe I can do this after all, and taken up Kotlin. I want to do a couple of apps for efficiency and store tracking at my current employer to see if I'm capable and not just an mit app-inventor codemonkey after all.
I'm hoping, by demonstrating what I can do, I can use that as a springboard into an internal programming position at my current gig (which seems to be a company thats moving towards a more tech oriented approach to efficiency and management). Also watching money walk out the door due to inefficiency kinda pisses me off, and the thought of fixing those issues sounds really interesting. At the end of the day I just like learning new technologies, and maybe this is all just an excuse to pick up something new after spending so long on less serious work.
I still have a ways to go, but the prospect of working on B2B, and being able to offer technological solutions to common and recurring business needs excites the hell out of me..as cringy and over-repeated as that may sound.5 -
“I Pay $900 A Month for student loans.”
Not sure why there’s a video about this but let’s watch it...
*Sad music is playing*
“My name is _____ and I pay $900 a month for student loans..”
Yeah so what?
*Sad music continues*
??
*Woman makes a call and asks about when they’re going to make a student loan reform aggressively*
????
Then I realized my family was eligible for low income and I received Cal and Pell grants to pay for my tuition and living.
Then I realized that the salary for my computer science degree has numbed me to a point where $900 a month doesn’t seem too bad. Or awful. I mean I just leased a new car for my mom! And didn’t hesitate (only when having fun negotiating though).
Back then, I would be shocked. But it’s a surreal feeling to see now that I don’t. I was literally confused at the basis of this video. And now I’m surprised at my disconnect from it.
I also realized that they make videos based on how society should react to it. Am I an outcast to society because of this? Why am I not reacting the same way?
Maybe society (nowadays) would disdain me because I’ve come into high income like we all will because of our passion (and the demand for it).
But fuck society. It’s full of the very same people who use technology each and every day. Protesting for things they found trending on Twitter. The ones who refused to learn even though it’s a huge part of their lives. They’re the ones holding us back for an Engel’s Technological Utopia (idk if I’m even correct about the philosopher but anyways..)
We’re above them. We make things they’ll use and in massive numbers.
Don’t let them dictate what you should like. How you should act. Whether or not you should feel lonely while they’re posting pictures of fun times on Facebook.
We should be the ones doing that. Because we are the ones doing that.
That’s why we’re given the best to perform what we love most.
So devs, continue what you’re doing. Small or big, you’re still driving the world forward. Opening pull requests and contributing to open source projects. Answering questions on Stack Overflow not only for the person intended but for the beginner or even experienced professional who may stumble upon it later in a Google search.
And be highly rewarded for it. How society feels doesn’t matter any more when it comes to your passion. You’re important. Your work helps others in ways you can’t even imagine. We’re like one big fucking hivemind of engineers with the accessibility of the internet.
I love drinking on a Sunday!12 -
If programming languages were countries, which country would each language represent?
Disclaimer: its just a joke
Java: USA -- optimistic, powerful, likes to gloss over inconveniences.
C++: UK -- strong and exacting, but not so good at actually finishing things and tends to get overtaken by Java.
Python: The Netherlands. "Hey no problem, let'sh do it guysh!"
Ruby: France. Powerful, stylish and convinced of its own correctness, but somewhat ignored by everyone else.
Assembly language: India. Massive, deep, vitally important but full of problems.
Cobol: Russia. Once very powerful and written with managers in mind; but has ended up losing out.
SQL and PL/SQL: Germany. A solid, reliable workhorse of a language.
Javascript: Italy. Massively influential and loved by everyone, but breaks down easily.
Scala: Hungary. Technically pure and correct, but suffers from an unworkable obsession with grammar that will limit its future success.
C: Norway. Tough and dynamic, but not very exciting.
PHP: Brazil. A lot of beauty springs from it and it flaunts itself a lot, but it's secretly very conservative.
LISP: Iceland. Incredibly clever and well-organised, but icy and remote.
Perl: China. Able to do apparently almost anything, but rather inscrutable.
Swift: Japan. One minute it's nowhere, the next it's everywhere and your mobile phone relies on it.
C#: Switzerland. Beautiful and well thought-out, but expect to pay a lot if you want to get seriously involved.
R: Liechtenstein. Probably really amazing, especially if you're into big numbers, but no-one knows what it actually does.
Awk: North Korea. Stubbornly resists change, and its users appear to be unnaturally fond of it for reasons we can only speculate on.17 -
Password policy for a big water company site in Spain.
Translation: Between 6 and 10 characters (only letters and numbers, no spaces)
In guess they have a VARCHAR(10) password field in their db?!?2 -
Woohoo!!! I made it to 1000++s :) Now I feel less newbie-like around here :)
So... I don't want to shit-post, so in gratitude to all you guys for this awesome community you've built, specially @trogus and @dfox, I'll post here a list of my ideas/projects for the future, so you guys can have something to talk about or at least laugh at.
Here we go!
Current Project: Ensayador.
It's a webapp that intends to ease and help students write essays. I'm making it with history students in mind, but it should also help in other discipline's essay production. It will store the thesis, arguments, keywords and bibliography so students can create a guideline before the moment of writting. It will also let students catalogue their reads with the same fields they'd use for an essay: that is thesis, arguments, keywords and bibliography, for their further use in other essays. The bibliography field will consist on foreign keys to reads catalogued. The idea is to build upon the models natural/logical relations.
Apps: All the apps that will come next could be integrated in just one big app that I would call "ChatPo" ("Po" is a contextual word we use in my country when we end sentences, I think it derived from "Pues"). But I guess it's better to think about them as different apps, just so I don't find myself lost in a neverending side-project.
A subchat(similar to a subreddit)-based chat app:
An app where people can join/create sub-chats where they can talk about things they are interested in. In my country, this is normally done by facebook groups making a whatsapp group and posting the link in the group, but I think that an integrated app would let people find/create/join groups more easily. I'm not sure if this should work with nicknames or real names and phone numbers, but let's save that for the future.
A slack clone:
Yes, you read it right. I want to make a slack clone. You see, in my country, enterprise communications are shitty as hell: everything consists in emails and informal whatsapp groups. Slack solves all these problems, but nobody even knows what it is over here. I think a more localized solution would be perfect to fill this void, and it would be cool to make it myself (with a team of friends of course), and hopefully profit out of it.
A labour chat-app marketplace:
This is a big hybrid I'd like to make based on the premise of contracting services on a reliable manner and paying through the app. "Are you in need of a plumber, but don't know where to find a reliable one? Maybe you want a new look on your wall, but don't want to paint it yourself? Don't worry, we got you covered. In <Insert app name> you can find a professional perfect to suit your needs. Payment? It's just a tap away!". I guess you get the idea. I think wechat made something like this, I wonder how it worked out.
* Why so many chat apps? Well... I want to learn Erlang, it is something close to mythical to me, and it's perfect for the backend of a comms app. So I want to learn it and put it in practice in any of these ideas.*
Videogames:
Flat-land arena: A top down arena game based on the book "flat land". Different symmetrical shapes will fight on a 2d plane of existence, having different rotating and moving speeds, and attack mechanics. For example, the triangle could have a "lance" on the front, making it agressive but leaving the rest defenseless. The field of view will be small, but there'll be a 2d POV all around the screen, which will consist on a line that fills with the colors of surrounding objects, scaling from dark colors to lighter colors to give a sense of distance.
This read could help understand the concept better:
http://eldritchpress.org/eaa/...
A 2D darksouls-like class based adventure: I've thought very little about this, but it's a project I'm considering to build with my brothers. I hope we can make it.
Imposible/distant future projects:
History-reading AI: History is best teached when you start from a linguistic approach. That is, you first teach both the disciplinar vocabulary and the propper keywords, and from that you build on causality's logic. It would be cool to make an AI recognize keywords and disciplinary vocabulary to make sense of historical texts and maybe reformat them into another text/platform/database. (this is very close to the next idea)
Extensive Historical DB: A database containing the most historical phenomena posible, which is crazy, I know. It would be a neverending iterative software in which, through historical documents, it would store historical process, events, dates, figures, etc. All this would then be presented in a webapp in which you could query historical data and it would return it in a wikipedia like manner, but much more concize and prioritized, with links to documents about the data requested. This could be automated to an extent by History-reading AI.
I'm out of characters, but this was fun. Plus, I don't want this to be any more cringy than it already is.12 -
There's nothing like sitting on the edge of your seat when you see a monster batch of records get sent updates.
This system was built 5 years ago and it's "peak" batch size has been < 400 records in a day, it usually sits around < 100.
It's not a big system and just runs in the background. So yea small numbers for this guy.
today though, I thought something fell down and shit its self, someone decided to add a a few thousand records to this thing and update a fuck tonne of data (for this system anyway)😬
The damn thing is standing it's ground and churning, but fuck, the scale of things is beyond what we ever thought it would have to deal with at any one time.
Build for the insane benchmarks kids, one day... someone's going to drop an elephant on it.5 -
So recently I did a lot of research into the internals of Computers and CPUs.
And i'd like to share a result of mine.
First of all, take some time to look at the code down below. You see two assembler codes and two command lines.
The Assembler code is designed to test how the instructions "enter" and "leave" compare to manually doing what they are shortened to.
Enter and leave create a new Stackframe: this means, that they create a new temporary stack. The stack is where local variables are put to by the compiler. On the right side, you can see how I create my own stack by using
push rbp
mov rbp, rsp
sub rsp, 0
(I won't get into details behind why that works).
Okay. Why is this even relevant?
Well: there is the assumption that enter and leave are very slow. This is due to raw numbers:
In some paper I saw ( I couldn't find the link, i'm sorry), enter was said to use up 12 CPU cycles, while the manual stacking would require 3 (push + mov + sub => 1 + 1 + 1).
When I compile an empty function, I get pretty much what you'd expect just from the raw numbers of CPU cycles.
HOWEVER, then I add the dummy code in the middle:
mov eax, 123
add eax, 123543
mov ebx, 234
div ebx
and magically - both sides have the same result.
Why????
For one thing, there is CPU prefetching. This is the CPU loading in ram before its done executing the current instruction (this is how anti-debugger code works, btw. Might make another rant on that). Then there is the fact that the CPU usually starts work on the next instruction while the current instruction is processing IFF the register currently involved isnt involved in the next instruction (that would cause a lot of synchronisation problems). Now notice, that the CPU can't do any of that when manually entering and leaving. It can only start doing the mov eax, 1234 while performing the sub rsp, 0.
----------------
NOW: notice that the code on the right didn't take any precautions like making sure that the stack is big enough. If you sub too much stack at once, the stack will be exhausted, thats what we call a stack overflow. enter implements checks for that, and emits an interrupt if there is a SO (take this with a grain of salt, I couldn't find a resource backing this up). There are another type of checks I don't fully get (stack level checks) so I'd rather not make a fool of myself by writing about them.
Because of all those reasons I think that compilers should start using enter and leave again.

This post showed very well that bare numbers can often mislead.21 -
I've promised to do the Mozilla rant about the whole meritocracy thing a few days ago.. well, this is that. Along with some other stuff along the way. Haven't ranted for a couple of days man, shit happened! But losing 6 days that could've been spent on finishing my power supply project.. to a stupid cold, it got a little bit on my nerves, so that's what I've been working on for the time being. Hopefully I'll be able to finish it up in a couple of days.
1. COCKtail party thingy
Turns out that there's this conference in Brussels in a couple of days about the whole Article 13 copyright stuff. I've been letting a mail to the MEP's about it mature on my systems for a while now.. well, maturing or procrastinating, you be the judge 😛
Now I'm glad that I waited with that though. It's mostly a developer-centric insight into how the directive would be a horrible idea.. think AI, issues with context recognition, Tom Scott's video on Penistone and Scunthorpe etc etc. But maybe I can include some stuff from the event afterwards.
Also, if you're coming to the conference too, do let me know! Little devRant meet while we're at it, it'd be fucking great! I'll try to remember to bring my Christmas ducks, they've got these cute little Santa hats 😋
(P.S.: about the whole COCKtail, I saw the email while drunk and during registration I had to choose an email address.. I figured, feminazis are doing such a great job at going out of their way to find offense in everything, I figured that I'd make their job a little bit easier by sending a COCK bomb in my registration mail address, in the hopes that it finds its way to one of them.. evil, I know XD)
2. The whole feminazi stuff at Mozilla
So Mozilla hates meritocracy now? I've been wanting to rant about the big bad meritocracy for a while now. Thank you Mozilla for giving me an incentive to actually do it!
Meritocracy, feminazis think it's bad because it's about power relationships and discrimination, right? But what if I told you that that is exactly what makes great software great. Good code, good merit, is what's welcomed in software development.. or at least it should be. Because it's a job of fucking knowledge, experience, and quality! Also, meritocracy is a great thing because nobody cares if you're a professional developer in a suit, getting paid to work on a piece of OSS, or a homegamer neonazi who's coding shit in their underwear while wanking to child porn.. nobody fucking cares. If your code, your merit, is good, contribute ahead! Super inclusive, yet apparently bad because bad code is excluded to ensure the health of the project.
So what is the alternative to the big bad meritocracy? Inclusion (or as it's looked like in practice, more like exclusion) based on gender/sex, political orientation, things like that. But not actual fucking merit, the ability to write good code. How the fuck is politics and gender going to be any good at all to an inherently meritocratic craft?! Oh but yeah, it's great for inclusion. It's like females in tech. Artificial growth is just a matter of growth numbers and the only folks who like it are fucking HR and wanketeering cunts, and feminazis. Merit, that's what matters!! And have you ever considered that females are generally not interested in technology? Or for that matter, where's our inclusion movement for men in healthcare?! Gender equality my ass.
That's just my two cents on it of course. Meritocracy shouldn't be abandoned in tech. And even if it's just a matter of calling it something else. How the fuck is it a good idea to not call a pot a fucking pot just because someone might take offense at it?! It's meritocracy, call it fucking meritocracy!!! And while we're at it, call a master a fucking master and a slave a fucking slave!15 -
Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

So... did I mention I sometimes hate banks?
But I'll start at the beginning.
In the beginning, the big bang created the universe and evolution created humans, penguins, polar bea... oh well, fuck it, a couple million years fast forward...
Your trusted, local flightless bird walks into a bank to open an account. This, on its own, was a mistake, but opening an online bank account as a minor (which I was before I turned 18, because that was how things worked) was not that easy at the time.
So, yours truly of course signs a contract, binding me to follow the BSI Grundschutz (A basic security standard in Germany, it's not a law, but part of some contracts. It contains basic security advice like "don't run unknown software, install antivirus/firewall, use strong passwords", so it's just a basic prototype for a security policy).
The copy provided with my contract states a minimum password length of 8 (somewhat reasonable if you don't limit yourself to alphanumeric, include the entire UTF 8 standard and so on).
The bank's online banking password length is limited to 5 characters. So... fuck the contract, huh?
Calling support, they claimed that it is a "technical neccessity" (I never state my job when calling a support line. The more skilled people on the other hand notice it sooner or later, the others - why bother telling them) and that it is "stored encrypted". Why they use a nonstandard way of storing and encrypting it and making it that easy to brute-force it... no idea.
However, after three login attempts, the account is blocked, so a brute force attack turns into a DOS attack.
And since the only way to unblock it is to physically appear in a branch, you just would need to hit a couple thousand accounts in a neighbourhood (not a lot if you use bots and know a thing or two about the syntax of IBAN numbers) and fill up all the branches with lots of potential hostages for your planned heist or terrorist attack. Quite useful.
So, after getting nowhere with the support - After suggesting to change my username to something cryptic and insisting that their homegrown, 2FA would prevent attacks. Unless someone would login (which worked without 2FA because the 2FA only is used when moving money), report the card missing, request a new one to a different address and log in with that. Which, you know, is quite likely to happen and be blamed on the customer.
So... I went to cancel my account there - seeing as I could not fulfill my contract as a customer. I've signed to use a minimum password length of 8. I can only use a password length of 5.
Contract void. Sometimes, I love dealing with idiots.
And these people are in charge of billions of money, stock and assets. I think I'll move to... idk, Antarctica?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.

Gender Bending For Fun and Profit.
I love how in the 'make your avatar' area, if you select female, and then click facial hair, theres nothing to select from.
Like a massive fuck you to every gender bending "down with meritocracy" purple haired dicksniffer in sanfran.
Also I'm sorely disappoint for desk items, theres no
1. giant dildos
2. anime figures/weeb shit
3. mini monoliths (I asked the site devs about this, they replied "we can't do that dave.")
4. a shirtless option for my female avatar
5. edgy scrolling numbers and code, like in the matrix
6. hoodies. They're the modern leather jacket.
7. Big nasty gnarly biker beard which I'm currently in the process of growing. How am I supposed to intimidate other anonymous cowards and mock them over the size of their beard compared to my own avatar's e-beard size? It's quiet girthy and lengthy, I assure you!
This is completely unrelated, but I thought devducks were like quick one-off debug sessions that could be bought from other devrant users.
I was disappointed when I discovered it was just merch.
On the otherhand I'm glad as fuck it's not. Site would be flooded by broken-english speaking goat humping dickheads.
How am I supposed to show off my ability to code with completely unrelated avatar change ups when no one will allow me to emasculate my avatar?16 -
This “Auto save” feature in the latest app version is buggy..
-> new rant
-> prefilled with previous rant..
Anyway, here my actual rant begins.
Apple, go fuck yourself, seriously.. put your trillion dollars way up your arse...
Moved to Ireland, want to switch country..
“If you want to switch countries, cancel your Apple Music subscription first”..
so be it. Cancelled it..
“Your subscription will be cancelled in 28 days”.
FUCK YOU, YOU COCK SUCKING BASTARDS!!
I NEED TO SWITCH THE STORE TO BE ABLE TO DOWNLOAD BANKING APPS AND STUFF LIKE THAT..
But ok, I’m screwed in this regard..
Suddenly iMessage stopped working. This is kind of a big deal because I have unlimited data but only unlimited sms to Irish numbers and I need to communicate with people in Switzerland and Germany..
Internet works so I try to turn iMessage off and in again. But that doesn’t work.. i can only reactivate iMessage via WiFi.
So I go back to the hotel, reactivate iMessage..
“Verifying imessage” >> google..
Leads me to an Apple forum: “the verification of iMessage can take up to 24h”.
Are you fucking kidding me? I’m in a new country and rely on this overpriced shit..
Fun but sad fact, I have a second phone with me. IPhone 4 with iOS 7 and that thing WORKS!!
If this is where the future is going we’re all gonna die very soon.. plains crash, power plants explode but hey, at least they have data about it and it looks shiny. That’s all that matters..
Another reason to switch to android..
MacOs fucked me up so I already switched to windows + Linux. Next one will be getting rid of iOS, they don’t build small phones anymore anyway..1 -
CONTEST - Win big $$$ straight from Wisecrack!
For all those who participated in my original "cracking prime factorization" thread (and several I decided to add just because), I'm offering a whopping $5 to anyone who posts a 64 bit *product* of two primes, which I cant factor. Partly this is a thank you for putting up with me.
FIVE WHOLE DOLLARS! In 1909 money thats $124 dollars! Imagine how many horse and buggy rides you could buy with that back then! Or blowjobs!
Probably not a lot!
But still.
So the contest rules are simple:
Go to
https://asecuritysite.com/encryptio...
Enter 32 for the number of bits per prime, and generate a 64 bit product.
Post it here to enter the contest.
Products must be 64 bits, and the result of just *two* prime numbers. Smaller or larger bit lengths for products won't be accepted at this time.
I'm expecting a few entries on this. Entries will generally be processed in the order of submission, but I reserve the right to wave this rule.
After an entry is accepted, I'll post "challenge accepted. Factoring now."
And from that point on I have no more than 5 hours to factor the number, (but results usually arrive in 30-60 minutes).
If I fail to factor your product in the specified time (from the moment I indicate I've begun factoring), congratulations, you just won $5.
Payment will be made via venmo or other method at my discretion.
One entry per user. Participants from the original thread only, as well as those explicitly mentioned.
Limitations: Factoring shall be be done
1. without *any* table lookup of primes or equivalent measures, 2. using anything greater than an i3, 3. without the aid of a gpu, 4. without multithreading. 5. without the use of more than one machine.
FINALLY:
To claim your prize, post the original factors of your product here, after the deadline has passed.
And then I'll arrange payment of the prize.
You MUST post the factors of your product after the deadline, to confirm your product and claim your prize.99 -
I normally just have nightmares about the projects I'm working on, especially when I struggle with a bug for days. Those are usually about just me stressing out about it. However, I have a lot of dreams about computers/technology, not necessarily coding-related:
- datacenters were just potato fields. If you go work the field, you'd go data mining
- in Biology, when being taught how having children works, you only tell that "parenting is only chmod-ing the rights of your children until they become the owners themselves"
- IP addresses with emojis instead of numbers were a standard now and they actually managed to replace IPv4, because everyone was so into emojis. They named it IPvE
- I witnessed a new Big Bang when the 32-bit Unix time overflown in 2038, and we were all quantum bits3 -
This is a guide for technology noobies who wants to buy a laptop but have no idea what the SPECS are meaning.
1. Brand
If you like Apple, and love their !sleek design, go to the nearest Apple store and tell them "I want to buy one. Recommendations?"
If you don't like Apple, well, buy anything that fits you. Read more below.
2. Size
There are 11~15 inches, weight is 850g ~ 2+kg. Very many options. Buy whatever you like.
//Fun part coming
3. CPU
This is the power of the brain.
For example,
Pentium is Elementary Schoolers
i3 is Middle Schoolers
i5 is High Schoolers
i7 is University People
Dual-core is 2 people
Quad-core is 4 people
Quiz! What is i5 Dual-core?
A) 2 High Schoolers.
Easy peasy, right?
Now if you have a smartphone and ONLY use Messaging, Phone, and Whatsapp (lol), you can buy Pentium laptops.
If not, I recommend at least i3
Also, there are numbers behind those CPU, like i3-6100
6 means 6th generaton.
If the numbers are bigger, it is the most recent generation.
Think of 6xxx as Stone age people
7xxx as Bronze age people
8xxx as Iron age people
and so one.
4. RAM
This is the size of the desk.
There are 4GB, 8GB, 16GB, 32GB, and so one.
Think of 4GB as small desk to only put one book on it.
8GB as a desk to put a laptop with a keyboard and a mouse.
16GB as a normal sized desk to put some books, laptop, and food.
32GB as a boss sized desk.
And so one.
When you do multitasking, and the desk is too small...
You don't feel comfortable right?
It is good when there are spacious space.
Same with RAM.
But when the desk becomes larger, it gets expensive, so buy the one with the affordable price.
If you watch some YouTube videos in Chrome and do some document words with Office, buy at least 8GB. 16GB is recommended.
5. HDD/SSD
You take out the stuffs such as books and laptop from the basket (HDD/SSD), and put in your desk (RAM).
There are two kinds of baskets.
The super big ones, but because it is so big, it is bulky and hard to get stuffs out of the basket. But it is cheap. (HDD)
There are a bit smaller ones but expensive compared to the HDD, it is called SSD. This basket is right next to you, and it is super easy to get stuffs out of this basket. The opening time is faster as well.
SSDs were expensive, but as times go, it gets bigger as well, and cheaper. So most laptops are SSD these days.
There are 128GB, 256GB, 512GB, and 1024GB(=1TB), and so one. You can buy what you want. Recommend 256GB for normal use.
Game guy? At least 512GB.
6. Graphics
It is the eyesight.
Most computers doesn't have dedicated graphics card, it comes with the CPU. Intel CPUs has CPU + graphics, but the graphics powered by Intel isn't that good.
But NVIDIA graphics cards are great. Recommended for gamers. But it is a bit more expensive.
So TL;DR
Buying a laptop is
- Pick the person and the person's clothes (brand and design)
- Pick the space for the person to stay (RAM, SSD/HDD)
- Pick how smart they are (CPU)
- Pick how many (Core)
- Pick the generation (6xxx, 7xxx ....)
- Pick their eyesight (graphics)
And that's pretty much it.
Super easy to buy a laptop right?

When I was in 11th class, my school got a new setup for the school PCs. Instead of just resetting them every time they are shut down (to a state in which it contained a virus, great) and having shared files on a network drive (where everyone could delete anything), they used iServ. Apparently many schools started using that around that time, I heard many bad things about it, not only from my school.
Since school is sh*t and I had nothing better to do in computer class (they never taught us anything new anyway), I experimented with it. My main target was the storage limit. Logins on the school PCs were made with domain accounts, which also logged you in with the iServ account, then the user folder was synchronised with the iServ server. The storage limit there was given as 200MB or something of that order. To have some dummy files, I downloaded every program from portableapps.com, that was an easy way to get a lot of data without much manual effort. Then I copied that folder, which was located on the desktop, and pasted it onto the desktop. Then I took all of that and duplicated it again. And again and again and again... I watched the amount increate, 170MB, 180, 190, 200, I got a mail saying that my storage is full, 210, 220, 230, ... It just kept filling up with absolutely zero consequences.
At some point I started using the web interface to copy the files, which had even more interesting side effects: Apparently, while the server was copying huge amounts of files to itself, nobody in the entire iServ system could log in, neither on the web interface, nor on the PCs. But I didn't notice that at first, I thought just my account was busy and of course I didn't expect it to be this badly programmed that a single copy operation could lock the entire system. I was told later, but at that point the headmaster had already called in someone from the actual police, because they thought I had hacked into whatever. He basically said "don't do again pls" and left again. In the meantime, a teacher had told me to delete the files until a certain date, but he locked my account way earlier so that I couldn't even do it.
Btw, I now own a Minecraft account of which I can never change the security questions or reset the password, because the mail address doesn't exist anymore and I have no more contact to the person who gave it to me. I got that account as a price because I made the best program in a project week about Java, which greatly showed how much the computer classes helped the students learn programming: Of the ~20 students, only one other person actually had a program at the end of the challenge and it was something like hello world. I had translated a TI Basic program for approximating fractions from decimal numbers to Java.
The big irony about sending the police to me as the 1337_h4x0r: A classmate actually tried to hack into the server. He even managed to make it send a mail from someone else's account, as far as I know. And he found a way to put a file into any account, which he shortly considered to use to put a shutdown command into autostart. But of course, I must be the great hacker.3 -
I'm really not sure. When I was 7-8 years old, I liked to view source in IE, then I somehow managed to use Javascript in the browser. First only some dumb opening of windows. And I liked Batch, so I made some files for copying, backup and stuff.
Then I got to PHP during the years from some online tutorial about making dynamic websites. My website was more static than stone, but yeah, I did page loading with PHP! Awful experience anyway, because I had to install Xampp, get it work and other stuff. 11 years old or so. (and I used Xampp only as a fileserver between laptop and desktop later, because.. PHP4... just no.)
As 12 years old or so I experienced my first World of Warcraft (vanilla) on a custom server in an internet cafe and I thought it's a singleplayer game. When I found out that no, I googled how to make my own server (hated multiplayer back then and loved good games with huge storylines). Failed miserably with ManGOS, got something to work with ArcEMU. There I learned some C++ basic stuff, which I hoped would helped me to fix some bugs. When I opened the code I was like: "Suuure." and left it like that. I learned what a MySQL database is, broke it like four times when I forgot WHERE and still rather played with websites i.e. html, css, js and optionally php when I wanted to repair a webpage for the server. With a friend we managed to get the server work via Hamachi, was fun, the server died too soon. Then I got ManGOS to work, but there wasn't really any interest to make a server anymore, just singleplayer for the lore. (big warcraft fan, don't kick me :D )
I think it was when I was 13y.o. I went to Delphi/Pascal course, which I liked a lot from the beginning, even managed to use my code on old Knoppix via Lazarus(Pascal). At this age I really liked thoae Flash games which were still common to see everywhere. So I downloaded .swfs, opened and tried to understand it. Managed to pull some stuff from it and rewrite in Pascal. Nope, never again that crap.
About the same time I got to Flash files I discovered Java. It was kind of popular back then, so I thought let's give it a try. I liked Flash more. Seriously. I've never seen so much repetitiveness and stupid styling of a code. I had either IDE for compiling C++ or Pascal or notepad! You think I wanted my code kicked all over the place in multiple folders and files? No.
So back to Pascal. I made some apps for my old hobby, was quite satisfied with the result (quiz like app), but it still wasn't the thing. And I really thought I'd like to study CS.
I started to love PHP because of phpBB forums I worked on as 15 y.o. I guess. At the same time I think there was an optional subject at school, again with Pascal. I hated the subject, teacher spoke some kind of gibberish I didn't really understand back then at all and now I find it only as a really stupid explanation of loops and strings.
So I started to hate Pascal subject, but not really the lang itself. Still I wanted something simpler and more portable. Then I got to Python as hm, 17y.o. I think and at the same time to C++ with DevC++. That was time when I was still deciding which lang to choose as my main one (still playing with website, database and js).
Then I decided that learning language from some teacher in a class seriously pisses me off and I don't want to experience it again. I choose Python, but still made some little scripts in C++, which is funny, because Python was considered only as a scripting lang back then.
I haven't really find a cross-platform framework for C++, which would: a) be easy to install b) not require VisualStudio PayForMe 20xy c) have nice license if I managed to make something nice and distribute it. I found Unity3D though, so I played with Blender for models, Audacity for music and C# for code. Only beautiful memories with Unity. I still haven't thought I'm a programmer back then.
For Python however I found Kivy and I was playing with it on a phone for about a year. Still I haven't really know what to do back then, so I thought... I like math, numbers, coding, but I want to avoid studying physics. Economics here I go!
Now I'm in my third year at Uni, should be writing thesis, study hard and what I do? Code like never before, contribute, work on a 3D tutorial and play with Blender. Still I don't really think about myself as a programmer, rather hobby-coder.
So, to answer the question: how did I learn to program? Bashing to shit until it behaved like I desired i.e. try-fail learning. I wouldn't choose a different path.2 -
How do you teach non-technical coworkers to trust you're doing your work to the best of your ability? You know the type, they're used to having everything measured by simple numbers. Number big = good work. Number small = bad work or slacking off. The moment they run into something that doesn't work like this, their heads explode.4

So, just pulled another all-nighter..
On our platform I switched a quite big customer to another stock keeping system to pull them into automatic FEFO handling etc. Just a better stock keeping system overall.. I made it.. *self hi-5*
Evidently the crons caught that change, and CLEARED ALL THE STOCK LEVELS as they're now managed by said system...
Had to pull the counts, locations, expiry dates and lot numbers from the history table and old database fields, add them to an Excel sheet and then add all gathered locations by hand back into the new system, whilst also setting the new settings for them.
39 unique products that were gathered over 190+ sku objects... (Somebody didn't get object oriented, or was trying to KISS themselves, clearly...)
That's 6 hours of extra work for a stupid fuck up.. Oops? (:rant warehouse fuck up fuck dedication suspense stock keeping all nighter accident fulfillment dangit don't worry we'll test in production5 -
ok, fuck people. i mean the people who talk about things that are a big deal. you don't need to take a course in html/css to build a website, you need documentation.
people act like programming languages are a whole separate literacy. they're not. it is not a big deal, nor an accomplishment of any significance, to learn any language to a basic extent. variables, control flow, functions and scope should not be considered challenging topics, and people should stop bragging about them. i'm pretty sure this is because programming is new. as people, i think when something is new we tend to think of it as more complex and harder to understand. basic programming is not that.
ok that was a tangent from my real point. college is a scam. anyone can learn anything from books and the internet. any time you want to learn about something, go to google, and search "${my topic} site:*.github.io" and you'll have a page about that topic written by someone who is knowledgeable and passionate of the topic. colleges don't teach people how to think like these books/websites do. and i'm fucking sick of people who'd rather see a degree then a portfolio. fuck them shits bro. i can distinct my smart friends because my smart friends speak logically and enjoy becoming smarter. i would take the kid who watches aerodynamics videos on youtube and then built a plane over a kid who studied and got a five on his ap physics exam. watching then doing is better learning than watching and repeating. after all, creativity is not at all measured in our grades, and i'd like to argue that sometimes intelligence isn't even measured. i mean, people can say they're good at math, but the kids who talk about fibinnoci numbers and why there can never be two primes more than 7 (i if i remember properly) integers apart or the ones who prove cryptographic algorithms. i guess what i'm trying to say is the dumb kids aren't dumb and the smart kids aren't smart (well not that) but kids who are passionate and just do something instead of waiting for their degree to do the same thing are the best and brightest. i forgot what i was talking about. sorry it is almost 2 am and i am intoxicated , and i don't believe i got my point across very well either.7 -
Numbers (from mac) sucks big fucking time!
Its like assuming your retarded, I cant save a file .whatever without it trying to insert the fucking numbers extension...
While buying excel what do you recommend?1 -
So to test my server code that do calculations on large numbers that get above 10 digits 90% of the time.
The end users found a custom web page with basic javascript doing the calculations.
Now I get to explain why that doesn't work. -
Control your searches like an ADULT damn it!!!
So we have records that can have any of a bazillion different reference numbers associated with them. No big deal. Everyone does right?
Our customer's love to run reports and so we have this one option for "just look at a hell of a lot of reference numbers". I call it the 'fuck all' search.
Really it is just there to find something that you don't know where a rando string or number might be in the record and just want to do a "fuck all" search across a number of likely fields to find it... and then presumably you'd be an adult and refine your search from there. LOL yeah right...
Customers get lazy and include that stupid option in their reports and we get a lot of.
Customer: "I always run this report (that includes the fuck all search) and now it isn't working. I want records that have ID 2222."
Me: "Yeah well that was only working because you were rando typing '2222' in like several fields and it would find those .... but now you quit doing that so it won't find them. If you want ID 2222, click the drop down and search by 'ID'. That will find it right away."
Customer: "But I want to just search by 'fuck all search' to find it..."
Me: "But then you get all these other records too right?"
Customer: "Yeah but I just delete them out of the spreadsheet ... "
Me: "Look watch this <screen share> there, look all records with an ID of 2222 and no more extra records you need to delete!!! How great is that?"
Customer: "But why do I have to do it this way now, I want to do it the old way..."
ಠ_ಠ
(granted I could add their ID to the fuck all search but we try to avoid adding too much because it gets out of hand / stops being useful the more fuck all it gets)3 -
The eggs have to make a symmetrical pattern in the box otherwise something doesn't feel right.
They used to do boxes of 15, which worked perfectly. Now it's either 6 or 12, both of which potentially require you to adjust the number of eggs you eat to get a symmetrical pattern.
It is both necessary and sufficient that the number of holes in the egg box should be an odd number.
Nine and fifteen work really well. All the other odd numbers are either too big, or negative, or prime, which would be impractical.8 -

finally after months and months of just planning and doing boring stuff a piece of code that was really just fun to code and plan for some days:
i just wrote my first "real" parser for a simple DSL. so much fun! i just really can recommend that to everybody.
i've use a parser combinator. the concept of this parser combinator ist to combine simple parsers (like when it starts with a number or a "-" and continues with numbers then its an integer etc) into a big one. i've written it in c# and used "Sprache" first and after some time i switch to "Superpower". a really great lib, but lacks a bit of documentation. anyway, i've your're interested in these things and want learn how your "daily code" gets parsed i would recommend that to you! :)
greetings to all fellow devRanters and happy coding / parsing! :)1 -
I love Java, but whoever thought the set of Big numbers were a good idea, fuck them! My co-workers starting using them, setting a precedent. I tried to compare it to 0, the value was 0.00. totally different!(according to the BigFloat in Java)

Well kinda, more like first world problems.
I started freelancing almost three years ago, it took a lot of hard work, sweat blood and tears to get this whole thing running.
I am currently in a very good place, have a lot of retainer contracts and the awesome freedom that comes with being a freelancer.
Two days ago I got an offer from one of my clients, they really want to have me on board, full time, it's a small, already established startup company, that has big clients, they want me to go into partnership with them, see still haven't talked numbers but they are very "generous".
the idea is to get me ASAP full time on board and start working on a partnership contract specifying all the small details.
I love being a freelancer, the freedom is amazing, client acquisition is Eons away from being a problem, but I miss the team work, and I miss working on products and building teams, freelancers are kind of a lone wolves.
I love working with these clients, there is a lot of mutual respect, they are very transparent and we really are on the same wave.
This could be an amazing opportunity for the next steps in my carrier.
I'm having a hard time making a decision, I'm basically changing my mind about it every two hours...
I mean I guess I'm planning to open my own company at some point anyways... so maybe going into a small but stable company is the way to go..
What would you do?
Would you take the offer? Or would you keep freelancing?11 -
Could somebody please help me understand why the fucking hell does JS (I am talking about node.js, so backend) use 32bit integers in setTimeout and setInterval? I mean, I understand most of the choices regarding the language (I have chosen programming languages design and principles for my studies) and I am happily using it for almost 4 years. But I came across an occasion that I had to use big numbers in those functions and it took me a lot of time to figure out why the fuck my code was not working as it was supposed to.
If anyone has a good reason please elaborate. In the meantime I'll go punch some shit to calm down.10 -
So I made a couple slight modifications to the formula in the previous post and got some pretty cool results.
The original post is here:
https://devrant.com/rants/5632235/...
The default transformation from p, to the new product (call it p2) leads to *very* large products (even for products of the first 100 primes).
Take for example
a = 6229, b = 10477, p = a*b = 65261233
While the new product the formula generates, has a factor tree that contains our factor (a), the product is huge.
How huge?
6489397687944607231601420206388875594346703505936926682969449167115933666916914363806993605...
and
So huge I put the whole number in a pastebin here:
https://pastebin.com/1bC5kqGH
Now, that number DOES contain our example factor 6229. I demonstrated that in the prior post.
But first, it's huge, 2972 digits long, and second, many of its factors are huge too.
Right from the get go I had hunch, and did (p2 mod p) and the result was surprisingly small, much closer to the original product. Then just to see what happens I subtracted this result from the original product.
The modification looks like this:
(p-(((abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1)-p)%p))
The result is '49856916'
Thats within the ballpark of our original product.
And then I factored it.
1, 2, 3, 4, 6, 12, 23, 29, 46, 58, 69, 87, 92, 116, 138, 174, 276, 348, 667, 1334, 2001, 2668, 4002, 6229, 8004, 12458, 18687, 24916, 37374, 74748, 143267, 180641, 286534, 361282, 429801, 541923, 573068, 722564, 859602, 1083846, 1719204, 2167692, 4154743, 8309486, 12464229, 16618972, 24928458, 49856916
Well damn. It's not a-smooth or b-smooth (where 'smoothness' is defined as 'all factors are beneath some number n')
but this is far more approachable than just factoring the original product.
It still requires a value of i equal to
i = floor(a/2)
But the results are actually factorable now if this works for other products.
I rewrote the script and tested on a couple million products and added decimal support, and I'm happy to report it works.
Script is posted here if you want to test it yourself:
https://pastebin.com/RNu1iiQ8
What I'll do next is probably add some basic factorization of trivial primes
(say the first 100), and then figure out the average number of factors in each derived product.
I'm also still working on getting to values of i < a/2, but only having sporadic success.
It also means *very* large numbers (either a subset of them or universally) with *lots* of factors may be reducible to unique products with just two non-trivial factors, but thats a big question mark for now.

So i want to know how finances work for tech companies. There are a lot of big numbers that come up when we talk about a company's finances, but i don't understand why the tech people are so down in the ladder, or why those no.s are not associated with the tech teams
Like here's a statement :
"company x is valuable at $42billion , their annual turnover is $5billion. With a profit of $2billion. The ceo has a worth of $1.4billion and company's share are selling at $1500 per share. Person a,b,c of the company hold's 2,3,4% in stocks and the investor sequoia capital is thinking of providing an investment of $25million"
This is a hypothetical company, but if this company is also providing its members of tech team @$20-200k per annum (depending upon seniority), then is it relatively too less? I mean the company is playing with numbers in millions, people are being attributed with billions and yet a developer has to satisfy in those numbers.
Is it because we are being paid by the no. Of hours/time? Because i want to know what other ways are there in which those managers and ceos and investors are being paid? I have heard far too many stories about devs leaving their jobs and starting businesses, and I don't think its only because their boss was a dick1 -
I ranted about my new laptop and linux mint on it https://devrant.com/rants/1919501 and I said there will be a rant about the OSs I tried
So my new laptop is the Xiaomi notebook pro, with the highest config: i7/16g/256g/mx150 gpu/alu body/10h battery/perfect keyboard/great screen. Its Chinese, but Xiaomi... you kinda expect flaws, problems, but i watched all the reviews and knew about all the things, and the price was 35% down (836 + taxes = 997EUR) for a macbook pro clone? its a no brainer.. but i had a rattling vent (fixed with shoe glue lol) now its just loud in windows but not in linux, strange
I changed the Chinese windows on it to EN... worked perfect... but... It has 2 slots for NVMe ssd so i bought a 500gb one for the second slot, I put windows on that (because games, occasional insta story video edit, big files, anyway...) and put Ubuntu on the 256gb original ssd.. (to develop on that) and it was slow as fuck, I got errors all over the places, problems I never had before with ubuntu.. and mind you Windows had over 3000 MB/s for read and almost 2000 MB/s for write speeds on that disk... I was disappointed af. MIND YOU all my life I had Ubuntu on secondary old/slow laptops/pcs working JUST FINE... I still don't know what the fuck happened.. the ui was choppy to say the least and I just was not ready to accept that on this HW while windows worked like a charm (yuck)
Then I went with Manjaro (based on arch, here on devrant people like that stuff, must be great)... well after I installed it, it booted up to the login page and black screen... something with the MX150 GPU according to the interwebs... by this time I was so frustrated and in time stress because of my flight home for xmas that I decided not to fix Manjaro but to go with another flavour
Linux Mint it is... everything kinda works out of the box, like they say... it has dark mode everywhere in the settings without downloading some bloated theme or plugin like on other flavours. So I sticked with Linux Mint. Im not saying its perfect, but I have it for like a month now and all its flaws are these small irrelevant settings not working, utilities like the battery showing funny numbers in the post I linked in the beginning.
Other than this I want to ask you guys. In all 3 distros I tried, they all had text scaling issues everywhere (os, apps, web). I think I have a regular fullHD display, its sharp, but I mean... I never expected resolution or scaling issues or things like that. On Windows I never had those scaling issues... other than the famous win10 "blurry apps"3 -
So we now do continuous deployment to a development environment. Once a PR gets merged it gets deployed there. We then have to manually deploy to staging every so often.
We did this because QA wined that the Dev was constantly breaking Staging, when we contentiously deployed to that.
So now we have a staging instance that is always behind. Which isn't big deal, because its supposed to be stable right?
Well now the stupid fucking QA team is always making mountains of tickets and noise for stuff that is already fixed on the development instance.
Fucking shit that they message me about, or have to call me about. "Hey let me tell me about this thing I found." And then I'm like I already fixed that thing last week.
So it seems to be wasting everyone time to not just CDCI into staging. I have to wait weeks to retest my bugs on staging. To make sure that some other stupid fuckeshir on my team didn't undo or break my fucking fix. Shit keeps getting kicked out of QA Review. Fuck. lol.
Then there like I can update the thing on the database through the front end tool. Well tough shit buddy, your going to have to wait a week unti next staging deployment to see if that tool is fixed. This is your fault for fucking up our pure CDCI with your ideas. Now everything takes longer for everyody.
To sum things up. Some dumb bug makes it into the manual staging deployment and gets fixed an hour later. Doesn't get deployed until next fucking week. QA makes a bunch of noise about it. A thing that is fixed and in the pipe-line.
Also a dumb fucking bug will make it into staging, lets say a critical front-end back office tool that needs to send numbers to the backend, they send a fucking string instead of a number and break it. Now we have to redeploy the tool and backend to staging because there related. Then if we deploy backend we have to deploy the client facing site too. since it also depends on backend.
Its a fucking hassle.
Now if the fucking DevOps guy could do his job, and make a god-damn deploy button for all the staging servers that would be great.1 -
I hate that unionization in our field is so pathetic. Sure, now we're still enjoying the benefits of being the aristocracy of labor with comfy positions, but that can change any moment and soon it will, with all the big companies firing now the massive numbers - and not having the solidarity now will render us all defenseless then.2

Why is it a big deal that arrays start att zero and the length att One? It's logical... Arrays as an index in memory and length as the... Length of the array (numbers of possible objects in the array)4

A quick question, is the numbers in the degree matters for working as dev? Student here. Big thanks ✌️7

Is any of it real? I mean, look at this. Look at it! A world built on fantasy. Synthetic emotions in the form of pills. Psychological warfare in the form of advertising. Mind-altering chemicals in the form of... food! Brainwashing seminars in the form of media. Controlled isolated bubbles in the form of social networks. Real? You want to talk about reality? We haven't lived in anything remotely close to it since the turn of the century. We turned it off, took out the batteries, snacked on a bag of GMOs while we tossed the remnants in the ever-expanding Dumpster of the human condition. We live in branded houses trademarked by corporations built on bipolar numbers jumping up and down on digital displays, hypnotizing us into the biggest slumber mankind has ever seen. You have to dig pretty deep, kiddo, before you can find anything real. We live in a kingdom of bullshit. A kingdom you've lived in for far too long. So don't tell me about not being real. I'm no less real than the fucking beef patty in your Big Mac.3

Why do we still use floating-point numbers? Why not use fixed-point?
Floating-point has precision errors, and for some reason each language has a different level of error, despite all running on the same processor.
Fixed-point numbers don't have precision issues (unless you get way too big, but then you have another problem), and while they might be a bit slower, I don't think there is enough of a difference in speed to justify the (imho) stupid, continued use of floating-point numbers.
Did you know some (low power) processors don't have a floating-point processor? That effectively makes it pointless to use floating-point, it offers no advantage over fixed-point.
Please, use a type like Decimal, or suggest that your language of choice adds support for it, if it doesn't yet.
There's no need to suffer from floating-point accuracy issues.26 -
So, management seem laser focused on hiring folks with work visa. What’s up with that? The latest five new employees. At least two of them utterly useless (have not worked with the others).
These are devs. ”Senior” as stated by closest manager. 😬 Yeah…ok.
It such a worthless leadership. It’s alot about
”We successfully filled the position for a senior developer”
or
”I am happy to announce that the new release manager for system X has been hired”
All about numbers. Closing the deal. Never about quality.
I guess salary is a BIG issue here and that is why we see this. I have no problem with VISA employees. But they seem bad at what-they-are-doing. Just…incompetent. *sigh*2
