So the person from my previous rant actually tried to make AI in HTML.

Person: I made that AI in HTML today!

Me: Oh really?

Person: Yup. *Opens HTML site*

It was a site that

1) Used JavaScript
2) Was a prompt(), and after answering it alerts "Yes" or "No" randomly.

Me: That's not AI

Person: Uhh yeah it is. It uses a neural network to answer!

Me: Actually, a neural network is a dot product of an input and vectors that are refined using partial derivatives.

Person: Yeah! That's what Math.random() and alert() do!

I left that room as quickly as I could (yet again).

Started being a Teaching Assistant for Intro to Programming at the uni I study at a while ago and, although it's not entirely my piece of cake, here are some "highlights":

* students were asked to use functions, so someone was ingenious (laughed my ass off for this one):
def all_lines(input):
all_lines =input
return all_lines

* "you need to use functions" part 2
*moves the whole code from main to a function*

* for Math-related coding assignments, someone was always reading the input as a string and parsing it, instead of reading it as numbers, and was incredibly surprised that he can do the latter "I always thought you can't read numbers! Technology has gone so far!"

* for an assignment requiring a class with 3 private variables, someone actually declared each variable needed as a vector and was handling all these 3 vectors as 3D matrices

* because the lecturer specified that the length of the program does not matter, as long as it does its job and is well-written, someone wrote a 100-lines program on one single line

* someone was spamming me with emails to tell me that the grade I gave them was unfair (on the reason that it was directly crashing when run), because it was running on their machine (they included pictures), but was not running on mine, because "my Python version was expired". They sent at least 20 emails in less than 2h

* "But if it works, why do I still have to make it look better and more understandable?"

* "can't we assume the input is always going to be correct? Who'd want to type in garbage?"

* *writes 10 if-statements that could be basically replaced by one for-loop*
"okay, here, you can use a for-loop"
*writes the for loop, includes all the if-statements from before, one for each of the 10 values the for-loop variable gets*

* this picture

N.B.: depending on how many others I remember, I may include them in the comments afterwards

To become an engineer (CS/IT) in India, you have to study:
1. 3 papers in Physics (2 mechanics, 1 optics)
2. 1 paper in Chemistry
3. 2 papers in English (1 grammar, 1 professional communication). Sometimes 3 papers will be there.
4. 6 papers in Mathematics (sequences, series, linear algebra, complex numbers and related stuff, vectors and 3D geometry, differential calculus, integral calculus, maxima/minima, differential equations, descrete mathematics)
5. 1 paper in Economics
6. 1 paper in Business Management
7. 1 paper in Engineering Drawing (drawing random nuts and bolts, locus of point etc)
8. 1 paper in Electronics
9. 1 paper in Mechanical Workshop (sheet metal, wooden work, moulding, metal casting, fitting, lathe machine, milling machine, various drills)
And when you jump in real life scenario, you encounter source/revision/version control, profilers, build server, automated build toolchains, scripts, refactoring, debugging, optimizations etc. As a matter of fact none of these are touched in the course.
Sure, they teach you a large set of algorithms, but they don't tell you when to prefer insertion sort over quick sort, quick sort over merge sort etc. They teach you Las Vegas and Monte Carlo algorithms, but they don't tell you that the randomizer in question should pass Die Hard test (and then you wonder why algorithm is not working as expected). They teach compiler theory, but you cannot write a simple parser after passing the course. They taught you multicore architecture and multicore programming, but you don't know how to detect and fix a race condition. You passed entire engineering course with flying colors, and yet you don't know ABC of debugging (I wish you encounter some notorious heisenbug really soon). They taught 2-3 programming languages, and yet you cannot explain simple variable declaration.
And then, they say that you should have knowledge of multiple fields. Oh well! you don't have any damn idea about your major, and now you are talking about knowledge in multiple fields?
What is the point of such education?
PS: I am tired of interviewing shitty candidates with flying colours in their marksheets. Go kids, learn some real stuff first, and then talk some random bullshit.

Crap! R starts its vectors with index 1!!!!!!!

- devRant TOR rant! -

There is a recent post that just basically says 'fuck TOR' and it catches unfortunate amount of attention in the wrong way and many people seem to aggree with that, so it's about time I rant about a rant!

First of all, TOR never promised encryption. It's just used as an anonymizer tool which will get your request through its nodes and to the original destination it's supposed to arrive at.

Let's assume you're logging in over an unencrypted connection over TOR and your login information was stolen because of a bad exit node. Is your privacy now under threat? Even then, no! Unless of course you had decided to use your personal information for that login data!

And what does that even have to do with the US government having funded this project even if it's 100%? Are we all conspiracy theorists now?

Let's please stop the spread of bs and fear mongering so that we can talk about actual threats and attack vectors on the TOR network. Because we really don't have any other reliable means to stop a widely implemented censorship.

I hope I'll graduate soon ;_;

And once again:
18:00: *writing a Mandelbrot algo in glsl for the GPU*
19:00: "This should be working now..."
22:00: "why isn't it working??!"
22:30: "Oh my uniform vectors become zero when they arrive on the GPU"
01:00: "Oh. I uploaded them as matrices..."

I wasted about 4 fucking hours because I suck dick.

There are two types of programmers

I started saying 'yes' to every opportunity in life. Long story short, I have 3 websites, 2 logos, a couple of leaflets and 2 non-profit websites due yesterday. Whiskey with cereal never tasted better at 8 AM!

Pleb designers who don't send vectors can you fuck off

dammit. I fucking hate it when I get stuck because of low level computing concepts and there is no explanation on Google.

like.. I understand the difference between an int and a float, but no one ever explains how you convert 32bit signed vectors to floats. or how bgra and rgba differ. or how to composite two images on a GPU. etc. the internet is great and all, but fuck, sometimes it seems as everyone is just as dumb as I am.

math be like:

"Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined. For example, in the adjacent picture, there is a combination of three apples and two apples together, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" i.e., "3 add 2 is equal to 5".

Besides counting items, addition can also be defined on other types of numbers, such as integers, real numbers and complex numbers. This is part of arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can be performed on abstract objects such as vectors and matrices.

Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.

Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some members of other animal species. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day."

And you think like .. easy, but then you turn the page:

Why the hate towards broccoli?

R is the worst language.

* Indices start at 1, so you have to fix all your calculations by either +1 oder -1. It sucks

* Vectors and Lists are both neither vectors nor lists

* Data frames dont have a proper api. Simple operations like add or remove are a pain.

* The naming „conventions“ suck. Why on earth would add dots in your identifiers? You never know if its an object, a value, a function.

* The namespace is cluttered. If you import two libraries that deal with the same problem domain, it is likely that they define functions with clashing names that will overwrite each other defined on import.

Oh boy I got a few. I could tell you stories about very stupid xss vectors like tracking IDs that get properly sanitized when they come through the url but as soon as you go to the next page and the backend returns them they are trusted and put into the Dom unsanitized or an error page for a wrong token / transaction id combo that accidentally set the same auth cookie as the valid combination but I guess the title "dumbest" would go to another one, if only for the management response to it.

Without being to precise let's just say our website contained a service to send a formally correct email or fax to your provider to cancel your mobile contract, nice thing really. You put in all your personal information and then you could hit a button to send your cancelation and get redirected to a page that also allows you to download a pdf with the sent cancelation (including all your personal data). That page was secured by a cancelation id and a (totally save) 16 characters long security token.

Now, a few months ago I tested a small change on the cancelation service and noticed a rather interesting detail : The same email always results in the same (totally save) security token...
So I tried again and sure, the token seemed to be generated from the email, well so much about "totally save". Of course this was a minor problem since our cancelation ids were strong uuids that would be incredibly hard to brute force, right? Well of course they weren't, they counted up. So at that point you could take an email, send a cancelation, get the token and just count down from your id until you hit a 200 and download the pdf with all that juicy user data, nice.

Well, of course now I raised a critical ticket and the issue was fixed as soon as possible, right?
Of course not. Well I raised the ticket, I made it critical and personally went to the ceo to make sure its prioritized. The next day I get an email from jira that the issue now was minor because "its in the code since 2017 and wasn't exploited".

Well, long story short, I argued a lot and in the end it came to the point where I, as QA, wrote a fix to create a proper token because management just "didn't see the need" to secure such a "hard to find problem". Well, before that I sent them a zip file containing 84 pdfs I scrapped in a night and the message that they can be happy I signed an NDA.

What do you do when your client WANTS a shitty website?
If it's considered a UI anti-pattern, he wants it.

I'm pretty frustrated because I keep bringing him what I consider professional-quality work and he's disappointed, asks for something dumb instead. I made the mistake of giving him Photoshop and encouraging him to try to design some of his ideas. I thought he would be frustrated and decide, okay, Patrick knows best. But that backfired. Now I'm forced to answer basic questions about "how to delete the pixels" and end up on TeamViewer for hours trying to explain vector masks.

His current bright idea is to advertise his product with a comic strip. And let me tell you, it looks really, really awful. Not tasteful material-design-esq vectors, he thinks those are dumb, he prefers crude clipart. But he loves it.

I've kind of dug myself a hole here. It's what the client wants. But the client wants a steaming pile of shit. What do I do? Also forgot to mention, dude is my landlord and I'm behind on rent. FML

pic related; it's his comic

Unreal Engine + third party library adventures part2:

now we gotta parse everything from unreal formats, to the library formats, than back to unreal again... sigh. Why can't it just use normal data formats like everybody else? I mean, come on, strings, ints, vectors etc. they all have standart libraries. why does unreal need to make their own shiet out of it. Just why...

Spent hours fixing my homework using arrays, when re-reading the exercise I found out I was supposed to use vectors. Well fuck me!

Okay, had a freelance JavaScript gig (with Three.js 3d lib). Usually I put the code on github so I have easier time switching between Desktop and laptop during work, unless I have to sign an NDA or something. Today at 5 AM I got mail from freelancing site support that client reported me for having code on public repo (but it's not like it is a proprietary software, it's based on threejs editor). I made repo private and went to sleep. Later I'm reading through messages, guy was cursing me, threatend to sue me etc. Ended up dropping the client. Did I do something really unprofessional? Unless I'm told not to, I want to show my code and I don't believe in not showing it by default. What do you guys think?

Ok so I'm a high school student in grade 11 looking to get a degree in computer sciences. I looked at the requirements for big Universitys in Canada and they say you only NEED calculous and vectors and no sciences. I wasn't sure if not taking sciences will impact my acceptance probability or if any of you got accepted to universities without highschool science.

There's nothing funnier than talking to another programmer around a group of non programmers. Feel like the fucking rick and morty memes when you go "Hey bro. I heard you were having issues with finding the direction between two vectors, are you telling me you don't know that the direction is basically x1-x2 and y1 - y2? Just be glad you arent trying to rotate the object towards the second one with quaternions. I know eulers work but its still a pain in the ass to figure out the euler direction." And everyone sits there looking at you like youre speaking minecraft enchanting table

Why is vectorization library faster than hand-written for loops ? I mean, somewhere down the line, the matrices/vectors must be multiplied (or any other operation) and thus be one-by-one (for loop??) calculated and stored.

Why is it then faster to use these libraries than just manually writing for loops all over the place ?

I guess some low level magic (OpenBLAS ?) goes on there but I just don't see it..

P.S. [Would have posted it on stack overflow but I'd be ripped apart so I'm pioneering new ways]

Been coding with python and like I mean I barely know any other language. So my school asked me if I wanted to go for an olympiad and i was like sure. Python is an accepted language but c++ is the recommended there so I go for the course offered by the organisers. On the schedule it was written that we were gonna learn the syntax of c++ on the first day. I go in, see everyone codng like mad and the organiser comes up to me and is like oh this is a pre course contest. MOREOVER, after the contest which I fucked up because like I dont know c++ and the course was in c++, the trainer spends the entire break playing osu and afterwards during the actual lecture dives straight into vectors and stacks and my brain was melting. mfw he said "does everybody remember". I swear it was the worst course ever. Sorry for such an unorganised and long rant. Had a rough day

I started Aeronautical Engeneering (yes I know, but I love Aviation). In second semester I saw Basic Programming, and then I realized that I had an ability in programming (comparing to my other fellows).

In third semester I was in "Static" class (vectors and a lot of physics) and I thought: "WTF am doing here, I don't know what can I do with a vector in real life." So I decided to switch to Systems Engeneering in other university (I think it had been always in my blood haha).

I saw one semester and this happened: I loved the career, but the university had an old-educational method that i hated. So i moved to another university, and I'm currently finishing at distance.

I'm just tired of university. I realized that the university is about 30%. The other 70% is experience (and of course a little from Stack Overflow hahaha).

Now, thanks to a lot of Google research and experience in various self projects, I'm here in Brazil working as a Web Developer.

I've learned 1000% more here than in the university.

And that's my short-four-years-story

Any Devs after college (CS)? Does studying CS at University made you a better developer, better person? Was it a waste of time? Looking for any motivation, attending college in my country is free

Anyone tried converting speech waveforms to some type of image and then using those as training data for a stable diffusion model?

Hypothetically it should generate "ultrarealistic" waveforms for phonemes, for any given style of voice. The training labels are naturally the words or phonemes themselves, in text format (well, embedding vectors fwiw)

After that it's a matter of testing text-to-image, which should generate the relevant phonemes as images of waveforms (or your given visual representation, however you choose to pack it)

I would have tried this myself but I only have 3gb vram.

Even rudimentary voice generation that produces recognizable words from text input, would be interesting to see implemented and maybe a first for SD.

In other news:
Implementing SQL for an identity explorer. Basically the system generates sets of values for given known identities, and stores the formulas as strings, along with the values.
For any given value test set we can then cross reference to look up equivalent identities. And then we can test if these same identities hold for other test sets of actual variable values. If not, the identity string cam be removed, or gophered elsewhere in the database for further exploration and experimentation.

I'm hoping by doing this, I can somewhat automate the process of finding identities, instead of relying on logs and using the OS built-in text search for test value (which I can then look up in the files that show up, and cross reference the logged equations that produced those values), which I use to find new identities.

I was even considering processing the logs of equations and identities as some form of training data perhaps for a ML system that generates plausible new identities but that's a little outside my reach I think.

Finally, now that I know the new modular function converts semiprimes into numbers with larger factor trees, I'm thinking of writing a visual browser that maps the connections from factor tree to factor tree, making them expandable and collapsible, andallowong adjusting the formula and regenerating trees on the fly.

Today a recruiter messaged me on Facebook. Week ago, I left a post with my CV on a programming group-currently I'm looking for a junior JAVASCRIPT (important ! ) /Node.js position, explicitly said so.

R(ecruiter): "Hello sir, we noticed your post with CV on group XYZ, are you still looking for a job?"
Me: "Yes, of course."
R: "We are building a new team in city X, remote work is possible. I will send you job posting right away."

Started reading it, job title is SENIOR JAVA DEVELOPER. Okay, maybe she sent me wrong document, maybe she wanted me to read just a bit about company and every job posting is pretty generic.

Me:" This job posting is for a senior programmer, I take it you're looking for juniors too ? I would happily take it, it's just I want a job to learn more things. Did you read my CV?"
R, annoyed: "Requirements for this position are quite clear, I believe. We are open to working with people with different experience level."

From there, she was pretty negative but I remained sympathetic and agreed to met with her boss next week. After all, maybe he has a position for me.

Can someone suggest me a quick way to create some svg files or convert some basic flat shapes like image of a redcircle or a blue heart into .SVGs?

I don't have any experience in graphics development, so online/offline tools or converstion engines would be also nice.

I wrote a type checking utility that also considers all types (JS without TypeScript, so this meant arrays etc.). The desired type had to be declared in a config file and the data didn’t even come from the config.

What would I not do to prevent all possible attack vectors...

When you receive a psd file with a million layers, when all you really need from it is the colour values and what font/size they've used and some measurements. You'll just do it all properly with CSS. Better off with a flat png or 2 with transparency and some original vectors.

Why must pixel perfect scaling be so fucking hard... It all works perfectly but I'm limited to a max of 540p for the games camera view but as soon as you drop your resolution bellow 1080p you get stuck with 300p or lower... Ughhhhhhhh

Why did I choose to do pixel art... Wonder if converting everything to vectors would help, wonder is smashing my head into a fucking wall would help...

Hackerman strikes back. Always thought the new knowledge about stego tools, reversing, enumeration, privesc were just my private amusement. But could now use it, hopefully resolving a severe crash by dropping our binary into radare2 (cutter) and ghidra, identifying some dangerous code.

Also it gives you new angles to look at things. E.g. the vectors your code might expose...

Haven't done much work on my game since December. Ok so I havent done anything on my game since December. Learned Mockito and JUnit formally (finally) because that's what we'll be using at work.

Never really learnt unit testing prior, just knew it's power. I just need to find the right unit testing and mocking frameworks that work well with .net, C# and Unity3D and I'll be great.

I'll finally attempt to properly test that (those) annoying part(s) of my game. So many vectors to work out and often the object is moved to or along the wrong vector.

I'd always only imagined having to use stubs which is why I've never understood how unit testing would really help in such a dynamic environment as video game development. Especially as a one man team. Mocking is about to be my lifesaver.

Anyone able to suggest a good testing and/or mocking framework for C#, .Net, Unity3D?

When did we decide managing Users through Cloud REST architecture was more secure than having them in an underlying DB?

Because I can't put my finger on exactly why... but I don't like it and I think it's probably less secure... and just spawned from the need to be able to make user management a subscription based service like fucking everything? When a simple MySQL or postgres and some bcrypt somewhere would be both more secure and infinitely cheaper?

I'm more used to consuming REST API's than writing them. Can any you REST peeps help me understand how a REST API could be made as secure as a SQL DB connection for user management?

What do you think the attack vectors are for a REST API User Management? Like... what's the SQL injection of REST API? Pack some extra JSON somewhere or something?

At least if I can have faith my shit's not gonna get hacked because I have to use a 3rd party REST service for User Management of Users to my own fucking app I can maybe sleep tonight.

Nhot vectors are fucking lifesavers.

For me it's the difference between searching a (2500*70)^n solution space, vs 64220*m solution space.

Who on earth decided, that float64 is a suitable default datatype for one-hot vectors in numpy?
That's what I deserve for relying on reasonable implicit behaviour

I am building a synth program for producing waveforms such as binaural. The programs I have used in the past have been mediocre.

In that project I am working on a realtime scope to visualize the waveforms. It is fun to learn how to streamline moving data between parts of the application. Right now it has a lot of unnecessary data copying going on, and resizing of vectors. So I am reading some books on high performance C++ to learn how to do this better. As part of this I am thinking about building a circular buffer so the vector is never resized and is always in contiguous memory.

Just plain fun!

If C++ invented mathematical vectors, the arrow symbol above the vector points would face the direction of the vector. The tip of the arrow missing would mean it's a zero-length vector, and, finally, if it faced to the right it wouldn't mean that it's a right-facing vector, it would be able to face in any direction. Because of course there should be multiple ways to do everything. It's so easy!

Okay, so I had an object consisting of tables (basically classes) and structs (classes with only scalars as their properties).

I was about to serialize the object with vectors of classes and structs and wrote some nice tests for it wondering why they fail to validate the data after deserialization and why I only got garbage for the vectors of structs whilst the tables worked just fine.

Turns out there is an undocumented function called CreateVectorOfStructs which shall be used for structs instead of the regular CreateVector ...

There go three hours of blaming memory issues and running Valgrind over and over again ...

I FUCKING HATE TYPEDEF.
I have NEVER seen a use of typedef that wasn't UTTERLY pointless AND did absolutely nothing except add obfuscation to code.

What the fuck is the point of typedeffing a size_t to "MapIndex".. And THEN typedeffing a vector... Of vectors... Of size_t (not MapIndex!) AND THEN TYPEDEFFING A MAP OF "MapIndex" to that previously typedeffed vector of vectors....

ITS FUCKING BEYOND STUPID. I absolutely hate typedef. I have never seen a single NOT RETARDED usage of it.

Have you?
