Holy fucking shit. I just went to my first Java class at uni (3 1/2 hour long one at that) and I havent felt so damn irritated in a while.

Some background:
So first, I only had about an hour of sleep last night and a full day of work before this class so I was more cranky than normal.
Theres only 7 students in the class, 6 others plus me. I am the only one with any resemblence of programming experience. The teacher also claims to be a linux developer.
This is a three part course series. Java 1, 2, and 3. All taught by the same teacher.

The fuckery:
-teacher spends 48 minutes talking about text editors. Not even IDEs. Just talking in depth as fuck about notepad (notepad. Not notepad++ )and atom and textpad. Those three only though, nothing on vim or emacs or ACTUAL IDEs. 48 minutes.
- I briefly mentioned learning node.js on the side and am now the "javascript girl" to my teacher. I'm probably less experienced with js than any other thing i ever practised or studied.
-professor saw linux on laptop and asked what distro. When I said arch he said "oh no you shouldnt be using that Its not really for beginners" ... Uhh what makes you think I'm a beginner to linux? Or does he not think I should be using arch while learning java? Either way its really ridiculous and irritates me that he would discourage anyone from using any software/OS/anything, regardless of what it is or skill level.
-teacher moved a bunch of content out of the course because theyre either "concepts that are never implemented anymore" or "arent critical to know to master the language". These particular topics that were removed? Multi-dimensional arrays, scopes, and exception handling. EXCEPTION HANDLING.
-he writes a hello world program and displays it on the board, proof of it working and everything. He tells the class to write the same program, compile and run it. Never did I guess we would spend the remaining hour and ten minutes of class struggling with fucking hello world programs. Especially when the correct code is on the fucking projector.

And I get it guys, everyone starts somewhere. People have to learn from square one. But these kids have no fucking interest in this. One of them literally admitted to pursuing this degree for the "lavish life" that comes with the salary. Others just picked programming because they didnt know what else to choose to get into the school. It fucking saddens me. I hope that one or some of them end up caring and finding a passion in this field, otherwise I feel fucking sorry for them having to spaghetti code their way through life to get a paycheck cause they couldnt be bothered to put in the effort. I feel even more sorry for any devs they work with in the future too.

The other annoying bit is that I can't test out of this class!! so it looks like for either 7 hours a week ill be bored out of my fucking mind with these beginner concepts or ill be helping others fix really stupid shit in their code (like putting quotes around hello world so it would actually print the string).

Fucking hell. Waste of a semester class.

Finally did my first rectangle in opengl in an sfml window in c++

It all began yesterday in my math lesson.My teacher introduced us into a new subject: The Heron method.
This is a method for iteratively computing the square root of a number which was made up by Hero of Alexandria.
But here's the cool part:
When my teacher said "method" I had the thought that I could make a programm on my TI-82 Stats (my calculator).
So I used the next break to make a little programm that does exactly the same what my mates has to do in several steps, in just one step.
Here is a picture so I can explain the programm:

First it asks for the root that it should calculate then for a value to begin with and finally for the amount of arithmetic operations.
Then it goes trough the algorithm and displays the interim results (this is important for later ...) .
So back in story.It wasn't surprising that we got exercises with this method as homework but through my programm I just needed 5 minutes instead of 20 minutes (like my class mates).

First contact with computers: draw a square using LOGO language. No idea which was the computer back then.

Why do people say "Well, I don't know about that" to voice disagreement?

If you admit your own naivety on a subject compared to your peers, if you admit that you do not have the required knowledge to have formed an opinion, how can you disagree?

So it can either be expressed with genuine innocence, like 'Well, I don't know about that, tell me more!', which is never the case.

Or it means "Well I don't know anything about that... and I'm ashamed of the fact that I can't find any counter argument, so I refuse to trust your fucking expertise, shut the fuck up until I give you the right to voice your knowledge"

Which is a bit rude.

Now that we're on the topic of annoying expressions and platitudes...

"It's not rocket science" -- Rocket science, understanding how a rocket works, is surprisingly simple. You fill a cylinder with fuel and oxygen, add a pump or two, put some sparks underneath. Chemical reaction equals energy, direct energetic particles using a nozzle, Newton's first law does the rest. It's so simple that people don't actually study rocket science. They study aerospace engineering, or astrodynamics, which are difficult topics.

So if someone says "Devops is not rocket science", they're right, but for the wrong reason. It's actually harder than rocket science. Maybe easier than developing thermal protection system materials or solving n-body orbital problems with a slide ruler though.

"Great minds think alike" -- No, great minds actually think creatively and generate unique thoughts, if two minds think alike, the solution was just fucking obvious.

"Don't reinvent the wheel" -- First of all, pretty much nothing in code looks or even remotely functions like a simple wheel. Even metaphorically, all existing code equates to oval or square wheels. If you said "Hey, don't bother making better wheels, I like my ride to be bumpy because it stimulates my asshole", say no more, who am I to come between a product manager and their anal stimulation.

Anyway, those were four coworkers who I would've strangled with an Ethernet cable if it weren't for a certain pandemic and the risk of infection which comes with choke-coughing.

What are your linguistic pet peeves you get homicidal over?

First story (not rant) :3

So I was asked to set problems for an online programming contest for my college (I'm a sophomore)

The participants were students from my college.

Teacher told me "make as hard as you can"

I gave it my all.

:|

1 person solved the first question. Nobody solved the other four. :|

Not sure if I should be proud or sad.

And if you're wondering - here was my first question -

Sam wants to invest in real estate. He's got X dollars to spend. He knows the expected value per square meter of a given property. He knows the coordinates of the vertices of the polygon shaped properties he's interested in.

(both the values and coordinates for each property are given in input)

Find the maximum return on investment he can get.

(answer is, basically you calculate the area of each polygonal house using half the vector cross product, multiply it with their expected value per square meter, and then apply a dynamic programming - knapsack approach)

;-; I really thought it was a nice question man. ;-; I put so much thought into others too. ;-;

Got ignored. ;-;

Friends of mine have a new flat.

It's a nice flat. Cheap. Noone wanted it. 100 square meters.

Reason noone wanted it...

Previous owners were bastards from hell.

Really. Every motherfucking room needed to be completely renovated by the owner.

Door frames were made of wood, nice and old - at least the part that was left of them. Splinters, scratch marks, partially broken out of the wall.

2 windows needed to be fully replaced. Rest of the windows needed to be bleached, PET abrasive cleaning solution and the frames needed repair with resin as they drilled into the frames. Then treatment with sealant of course.

Yes. There was no other solution. After bleaching you recognized the windows were white. Before... Let's not talk about it.

The previous owners even managed to destroy the bathtub.

The kitchen tiles... Fat cleaner. Bleaching. Abrasion. Polishing.

Soooo.

Day of moving.

The apartment is in the 6th floor / level.

Cran / lift was ordered.

16 people wanted to come.

7 people came.

2 including myself couldn't lift heavy stuff nor walk the stairs due to health issues.

Crane broke after first try.

Today. I want to murder the previous owners. After torture and crucification.

I'm feeling levels of pain I couldn't Imagine before.

Only hate and beer let's me keep my shit together.

I REALLY didn't think after renovating and cleaning the flat for my friends in the last several weeks that it could get worse.

Boy. I was wrong.

Thanks for letting me vent here. I really feel devastated currently -.-

And I need to help them tomorrow, too.

Bikini Atoll, tchernobyl and every other atom bomb desaster Zone combined looks better than the chaos in their flat.

Everyone who could lift shoved everything inside.

I solo carried everything that wasn't too large in the room and then, as every room looked like desaster, completely managed the kitchen (cleaning, unpacking, trash, placing everything where it belongs and so on) :( :(

I just started work school doing IT administration and development, I was excited, almost nervously anticipating to see the wondrous things I'd being learning and the kickass programs I'd be creating...

Alas I walked into my first lesson and...

Teacher: Today we're going to be learning how to make a square in Excel using VBR.

I thought, well fuck no - I didn't sign up for this shit. Then today I was on this thing called the internet, have you guys tried it? Amazing stuff, I saw a panda dressed as Chuck Norris... Anyway, I was on the internet and found out about this 73 year old man who makes full-sized artworks made in Excel.

Now I know the meaning to life, to Excel programming... It's official, I'm going to make Picasso in Excel.

*Light sarcasm, actual true story.*

Unemployment week 2

I finalized buying ~1000 square feet ( ~95 square meters ) apartment. Still renting 100 square feet room ( ~10 m2 ) so change will be tremendous. It’s first property I will own. With that amount of free space I think I can start constructing small spaceship or time travel machine.

Typed on linkedin that I’m offline.
Phone is still ringing. Time to turn it off for a while and rethink my life and world around from scratch.

Rest is good for my soul.
Peace ✌🏽

Boss: Use the same template that site [X] is using for this project.
Me: [X] is WordPress. Our project is asp.Net/C#. I can't
Boss: Why?
Me: You can't put a round peg in a square hole!
Boss: Why?
Me: [thinking about mortgage] I'll do it.
Boss: Why didn't you say so in the first place?
Me: [die a little inside]

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

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

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

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

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

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

# school suck
! coding

hello, hope im not bothering anyone with my adolescent problems, but im really angry towards school.

first of all,
the subjects get thaught much too slow.
like dafuq, why does our maths teacher need 6h to teach us what square roots are? Why does our history teacher need 10h to teach us about one single revolution???

and worst of all: why is everything accompagnied by long, repetitive, homework?

Also, why do they think that im bad just because i dont have the best grades??? im a GOOD average, without learning a TAD!!!

also, here i am, needing to learn maths for some it project.
when i ask any teacher, he doesnt explain it to me but says "you will learn that in class xy"

ok, then i guess i can teach it myself.
but when i take books into school to read em (remember, i already know the subjects), the teachers always take em from me.

also, im not allowed to talk to anyone. not even when idle.

so currently, i am trying not to get angry from this, tomorrow school starts again. after this year legally, i would be allowed to drop out.

could you please tell me what you would do? should i drop out? change school? change class? im open to reolly anything that possibly could help (my parents arent)

Need some opinions. Joined a new company recently (yippee!!!). Just getting to grips with everything at the minute. I'm working on mobile and I will be setting up a new team to take over a project from a remote team. Looking at their iOS and Android code and they are using RxSwift and RxJava in them.

Don't know a whole lot about the Android space yet, but on iOS I did look into Reactive Cocoa at one point, and really didn't like it. Does anyone here use Rx, or have an opinion about them, good or bad? I can learn them myself, i'm not looking for help with that, i'm more interested in opinions on the tools themselves.

My initial view (with a lack of experience in the area):

- I'm not a huge fan of frameworks like this that attempt to change the entire flow or structure of a language / platform. I like using third party libraries, but to me, its excessive to include something like this rather than just learning the in's / out's of the platform. I think the reactive approach has its use cases and i'm not knocking the it all together. I just feel like this is a little bit of forcing a square peg into a round hole. Swift wasn't designed to work like that and a big layer will need to be added in, in order to change it. I would want to see tremendous gains in order to justify it, and frankly I don't see it compared to other approaches.

- I do like the MVVM approach included with it, but i've easily managed to do similar with a handful of protocols that didn't require a new architecture and approach.

- Not sure if this is an RxSwift thing, or just how its implemented here. But all ViewControllers need to be created by using a coordinator first. This really bugs me because it means changing everything again. When I first opened this app, login was being skipped, trying to add it back in by selecting the default storyboard gave me "unwrapping a nil optional" errors, which took a little while to figure out what was going on. This, to me, again is changing too much in the platform that even the basic launching of a screen now needs to be changed. It will be confusing while trying to build a new team who may or may not know the tech.

- I'm concerned about hiring new staff and having to make sure that they know this, can learn it or are even happy to do so.

- I'm concerned about having a decrease in the community size to debug issues. Had horrible experiences with this in the past with hybrid tech.

- I'm concerned with bugs being introduced or patterns being changed in the tool itself. Because it changes and touches everything, it will be a nightmare to rip it out or use something else and we'll be stuck with the issue. This seems to have happened with ReactiveCocoa where they made a change to their approach that seems to have caused a divide in the community, with people splitting off into other tech.

- In this app we have base Swift, with RxSwift and RxCocoa on top, with AlamoFire on top of that, with Moya on that and RxMoya on top again. This to me is too much when only looking at basic screens and networking. I would be concerned that moving to something more complex that we might end up with a tonne of dependencies.

- There seems to be issues with the server (nothing to do with RxSwift) but the errors seem to be getting caught by RxSwift and turned into very vague and difficult to debug console logs. "RxSwift.RxError error 4" is not great. Now again this could be a "way its being used" issue as oppose to an issue with RxSwift itself. But again were back to a big middle layer sitting between me and what I want to access. I've already had issues with login seeming to have 2 states, success or wrong password, meaning its not telling the user whats actually wrong. Now i'm not sure if this is bad dev or bad tools, but I get a sense RxSwift is contributing to it in some fashion, at least in this specific use of it.

I'll leave it there for now, any opinions or advice would be appreciated.

300 global variables.. THREE HUNDRED FUCKING GLOBAL VARIABLES?
Are you for real?

Now let me check the line numbers again..

hmm.. line 97 to .. yep line 410, just a few new lines to seperate some of them or.. group? Idk, I've given up on trying to understand those.

Now you may ask "But ThatPerlDeb, where did you see this and what was the intention?"
Low and behold, take a chair and I may explain this to you.

First of all: Fuck the dev that wrote this!
Second: Fuck all the devs that kept up with this practice or whatever you want to fucking call this!

Now, the application is our POS system that our customers can use for a monthly fee (That this piece of garbage even requires payment is disgusting) but anyway..
The global variables sometimes are declared for labels, sometimes for some frames, sometimes just for random values to be there.

We're using Perl for the POS system and Perl ain't the best at OOP, so in the dev's defense I can understand why you'd use a few global variables, but not fucking 300!! FUCK OFF WITH THIS BULLSHIT!!

So now I'm going through this torture slowly but surely deleting globals and putting them into some sort of scope and always MANUALLY test if something broke. Again, this company sucks ass and there's nothing that could even be considered a "unit test" or something like that, so fuck that, too.

After two hours I've brought down the count of global variables to about 260, so there's progress being made..

But then, there comes more!

"But how???" you may ask, and you're right, I've asked that myself.

Now to resolve the global stuff in each file some of the initial globals are used, we got about 20-30 files which do different stuff, all fair and square, at least there was an attempt at seperating functions but god this mess is so fucking fucked up. So in order to "safely" delete a global variable I have to check if any of the variables are used in another file, and if so, in which scope and how they are used.

Spaghetti would be a compliment for this fucking disgusting piece of utter bullshit.

Let alone the code quality of this "code"
Indendation? Dafuq is dat?
Scope? Nah, we got everything global anyway
Function size? Well, some are 5 lines, some are 900 lines, who cares anyways, right?

I'm so fucking glad once I leave this shithole, for real.

My first interview was the interview where I cheated and got the job, it was an on campus job interview. I did not have a good gpa, (to be honest it was really bad i was below the 25th percentile)

Anyway this was the only (developer) job interview I knew I could qualify for, I was pretty sure that if I couldn't nail this one then I could kiss my dream of programming professionally good bye.

We were about 25 kids sitting in a class room with a pencil and couple of sheets of paper and the the interview panel walked between the seats looking at what we wrote.

So, when I couldn't write an algorithm for the problem of square rooting a number n. I panicked (was literally shivering with tears rolling down my cheeks, thankfully nobody saw me as i was on the last bench) I gave up, wiped my tears and stared at the board, a panel member saw me and told me to leave after looking at my paper. This was the moment my mind decided (not me but someone else inside me) that I have to do whatever it took, so just when I was stepping out and grabbed my bag i quickly opened the browser of my phone inside the bag typed square root algorithm opened the first result and read the words arrive at the answer by binary search, ass soon as I read that my mind worked at a pace that it has never managed ever since that time, and i knew the solution in a matter of seconds, i dropped my bag when to one of the more sympathetic panel members and explained the whole thing to him on the spot, he was impressed, and he asked me how this algorithm can be extended for the nth root(which is really simple once you have the algorithm for square root) and i blurted it out instantly which impressed him even more and offered me the job on the spot and told me to attend the next 2 rounds as a formality.

Thus i saved myself for a world of hurt and now I am a developer who thinks back to that day every time I need a boost of morale

TL;DR: Microsoft updates break drivers, make unbootable. Hours wasted. Such rage.

Lol. I come home, try booting my windows desktop. Need desperately to play some videogames. Power is on. Monitor lights up. Bios splash. Windows startup spinner.

Suddenly, windows startup spinner gone, monitor shuts off. Wait 5 minutes, no change. Force power off and reboot, same behavior.

Google says it's probably a bad video driver. I don't remember installing any in the last month, but heck I don't use this computer for shit outside of games, so may as well do a full OS reinstall and hope the problem drivers are gone.

Reboot and force power off halfway through boot to let windows know something's wrong next boot. Literally no other way to get to alternate boot methods.

Run the reset. First time, percent-counter starts. I leave the room at 30% to go get a sandwich. Come back and it says it's "undoing changes". Something went wrong and I have no way of knowing what.

Oh well, I'll just try again and see what the problem was. NOPE! Completes windows reinstall without a hitch on the second attempt.

Okay, now let's get my stuff back on here. First things first, Microsoft updates for my processor, graphics card, "security". Halfway through the updates, monitor shuts off and I'm back to square one. IT WAS THE MICROSOFT DRIVER, NOT THE ONE FROM NVIDIA GEFORCE EXPERIENCE!!!!

Fucking Microsoft. To all ye who rail against Linux as a gaming platform because of its unstable drivers, observe here the stupidity of Microsoft and weep.

Hi everyone, I'm a now second year computer science student. I have read through posts on Dev Rant for a while now and have loved every minute of it. I really wanted to start contributing to this awesome community and thought a question might be a good start. There seems to be a ton of inconsistencies among certain terms. The biggest that really grinds my gears is how people refer to "()", "[]", and "{}". I personally refer to the first set as parenthesis, the second as brackets, and the third as braces. Throughout my time at this college and around the internet I have read some people say curly braces, curly brackets, squigly brackets, round brackets, square braces, and my personal favorite "those curvy round things". Other students do this which is understandable, but it seemed strange that even my professors use them interchangeably. So is there a naming convention anywhere that might help with this issue or somewhere I can get some clarification?

Cracked my first weak RSA implementation challenge today. Feels pretty awesome.

Involved primes that were very close, which means you can factorize the modulus quickly to get the private key. Normally, you would never use close primes as prime factorization's difficulty relies a certain amount on some distance between the two values.

The reason you can brute force close primes has to do with them being close in value to the square root of the function, meaning that you can search far quicker than if you were to try every combination of primes.

Just remembered that I still had a foobar invite link in my email inbox 😋

The challenges are odd though, first challenge was super easy (basically an idiot check), but while I was able to convert 3 cans of energy drink into a functional solution in half an hour, the verification utility is not very verbose at all. So in Python 3.7.3 in my Debian box it worked just fine, yet the testing suite in Foobar was failing the whole time. After sending an email to my friend that gave the link (several years ago now, sorry about that! 😅) asking if he knew the problem, I found out that Google is still using Python 2.7.13 for some reason. Even Debian's Python is newer, at 2.7.16. To be fair it does still default to Python 2 too. But why.. why on Earth would you use Python 2.7 in a developer oriented set of challenges from a massive company, in 2020 when Python 2 has already been dead for almost a whole year?

But hey now that it's clear that it's Python 2.7, at least the next challenges should be a bit easier. Kind of my first time developing in SnekLang regardless actually, while the language doesn't have everything I'd expect (such as integer square root, at least not in Debian or the foobar challenge's interpreter), its math expressions are a lot cleaner than bash's (either expr or bc). So far I kinda like the language. 2-headed snake though and there's so much garbage for this language online, a lot more than there is for bash. I hate that. Half the stuff flat out doesn't work because it was written by someone who requires assistance to breathe.

Meh, here's to hoping that the next challenges will be smooth sailing :) after all most of the time spent on the first one (17.5 hours) was bottling up a solution for half an hour, tearing my hair out for a few hours on why Google's bloody verification tool wouldn't accept my functioning code (I wrote it for Python 3, assuming that that's what Google would be using), and 10 hours of sleep because no Google, I'm not scrubbing toilets for 48 hours. It's fair to warn people but no, I'm not gonna work for you as a cleaning lady! 😅

Other than the issues that the environment has, it's very fun to solve the challenges though. Fuck the theoretical questions with the whiteboard, all hiring processes should be like this!

So, I'm looking into something and end up on Stack Overflow. Someone posted the question:

"Does minified javascript improve performance?"

This question was old as shit, all they way from 07/25/09, and about an Adobe Air application. (Remember that? Me neither...) It had a great, accepted, and still accurate answer, posted the same day the question was asked. Now, fast forward 8 years and on 12/08/17 (A mere 7 months ago...) the following answer was posted. I don't know what they were thinking, but here it is, complete and unabridged, with my comments in square brackets:

"I'd like to post this as a separate answer as it somewhat contrasts the accepted one: [Somewhat contrasts? More like completely contradicts...]

Yes, it does make a performance difference as it reduces parsing time - and that's often the critical thing. For me, it was even just simply linear in the size and I could get it from 12s to 4s parse time by minifying from 3MB to 1MB. [First off, your parse time should NEVER be THE critical thing, but secondly, and more importantly, WHO THE FUCK HAS 1MB OF MINIFIED JS ON A PAGE!!!]

It's not a big app either, it just has a couple of reasonable dependencies. [THERE IS ABSOFUCKINGLUTELY NOTHING REASONABLE ABOUT ANYTHING HE JUST SAID! What dependancies is he using?! You could use minified and not even gzipped jQuery, AngularJS, Vue, Ember, React, AND Dojo libraries on the SAME PAGE, AND have 118k of application code, AND STILL NOT HAVE HIT 1MB QUITE YET!!!]

So the moral of the story here is: Yes, minifying is important for performance - and not because of bandwidth, but because of parsing. [Javascript should NEVER take longer to parse then to download, even on a low powered device...]"

So, yeah, I'm at a loss for what this guy was thinking, but the thought the people like this exist, and that my browser might one day be subjected to their horrific nightmare of code terrifies me...

Today, I have installed/uninstalled a combination of [windows 7, arch linux, dual-boot] a total of 9 times...

I wouldn't be surprised if my 120G SSD fails next week

It all started when I had to whip up a GUI-wrapped youtube-dl based program for a windows machine.

Thinking a handy GUI python library will get it done in no time, I started right away with the Kivy quick-start page in front of me.

Everything seemed to be going fine, until I decided it would be "wise" to first check if I can run Kivy on said windows machine.

Here I spent what felt like a day (5 hours) trying to install core pip modules for kivy.. only before realizing my innocent cygwin64 setup was the reason everything was failing, and that sys.platform was NOT set to "win32" (a requirement later discovered when unpacking .whl files)

"Okay.. you know what? Fuck........ This."
In a haze of frustration, I decided it was my fault for ever deciding to do Python on windows, and that "none of this would've happened if I were installing pip modules on a Linux terminal"...

I then had the "brilliant" idea of "Why don't I just use Linux, and make windows a virtual machine within, for testing."

And so I spent the next hour getting everything set up correctly for me get back to programming.... And so I did.

But uh... you're doing GUI stuff, right? -> Yeah...

And you uh.. Kivy uses OpenGL on windows, doesn't it? -> Yeah..?

OpenGL... 2.

-> Fuck.

That's when I realized my "brilliant" idea, was actually a really bad prank. Turns out.. I needed a native windows environment with up-to-date non-virtual graphics drivers that supported at least OpenGL2 for Kivy GUI programs!

Something I already had from square 1.

And at this point, it hurts to even sigh knowing I wasted hours just... making... poor decisions, my very first one being cygwin64 as a substitution for windows cmd.

But persistent as any programmer should be in order to succeed, I dragged my sorry ass back to the computer to reinstall windows on the actual hardware... again.

While the windows installer was busy jacking off all over my precious gigabytes (why does it need that much spaaace for a base install??? fuck.). I had "yet another brilliant idea" YABI™

Why not just do a dual-boot? That way, you have the best of both worlds, you do python stuff in Linux, and when it's time to build and test on the target OS, you have a native windows environment!

This synthetic harmony sounded amazing to the desperate, exhausted, shell of a man that I had become after such a back-breaking experience with cygwin

Now that my windows platter with a side of linux was all set-up and ready-to-go, I once again booted up windows to test if Kivy even worked.

And... It did!

And just as I began raising my victory flags, I suddenly realized there was one more thing I had to do, something trivial, should take me "no time" to do, being in a native windows environment and all.................... -.- (sigh)

I had to make sure it compiles to a traditional exe...

Not a biggy, right? Just find one of those py2exe—sounding modules or something, and surprisingly enough, there was indeed a py2exe—sounding module, conveniently named... py2exe.

Not a second thought given, I thought surely this was a good enough way of doing it, just gonna look up the py2exe guide and...

-> 3 hours later + 1 extra coffee

What do you meeeeean "module not found"? Do I need to install more dependencies? Why doesn't it say so in the DAMN guide? Wait I don't? Why are you showing me that error message then????

-------------------------------

No. I'm not doing this.
I shut off my computer and took a long... long.. break.

Only to return sometime the next day and end up making no progress, beating my SSD with more OS installs (sometimes with no obvious reason to do so).

Wondering whether I should give up Kivy itself as it didn't seem compatible with py2exe.. I discovered pyInstaller, which seemed to be the way Kivy wants exe's to be made on windows..

Awesome! I should've looked up how Kivy developers make exe's instead of jumping straight into py2exe land, (I guess "py2exe" just sounded more effective to me then)

More hours pass, and you'd think I'd have eliminated all of my build environment problems by now... but oh, how wrong you'd be...

pyInstaller was failing, and half the solutions I found online were to download some windows update KB32946..whatever...

The other half telling me to downgrade from Python 3.8.1 to Python 3.8.0000.009 (exaggeration! But you get the point)

At the end of all that mess, I decided it wasn't worth some of my lifespan, and that maybe.. just maybe.. it would've been better to create WINDOWS GUI with the mother fuc*ing WINDOWS API.

Alright, step 1: Get Visual Studio..
Step 2: kys
Step 3: kys again.

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

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

697 becomes -> 600, 90, and 7.

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

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

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

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

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

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

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

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

But actually we're searching

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

etc..

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

So for game dev we need to do a lot of writing. For an assignment we had to write 3 documents.

First has 8192 words, a power of 2.
Second has 3600 words, a nice square number.
Third is 2002, my birth year.

Just found it nice that they were all randomly a nice number.

I first got into programming when I was really young. I recall programming a square at a museum in Ohio, and after that I was hooked. I learned Logo and was on the web dev team for my elementary school while attending there. I used Hotdog HTML editor 😂

During my small tenure as the lead mobile developer for a logistics company I had to manage my stacks between native Android applications in Java and native apps in IOS.

Back then, swift was barely coming into version 3 and as such the transition was not trustworthy enough for me to discard Obj C. So I went with Obj C and kept my knowledge of Swift in the back. It was not difficult since I had always liked Obj C for some reason. The language was what made me click with pointers and understand them well enough to feel more comfortable with C as it was a strict superset from said language. It was enjoyable really and making apps for IOS made me appreciate the ecosystem that much better and realize the level of dedication that the engineering team at Apple used for their compilation protocols. It was my first exposure to ARC(Automatic Reference Counting) as a "form" of garbage collection per se. The tooling in particular was nice, normally with xcode you have a 50/50 chance of it being great or shit. For me it was a mixture of both really, but the number of crashes or unexpected behavior was FAR lesser than what I had in Android back when we still used eclipse and even when we started to use Android Studio.

Developing IOS apps was also what made me see why IOS apps have that distinctive shine and why their phones required less memory(RAM). It was a pleasant experience.

The whole ordeal also left me with a bad taste for Android development. Don't get me wrong, I love my Android phones. But I firmly believe that unless you pay top dollar for an android manufacturer such as Samsung, motorla or lg then you will have lag galore. And man.....everyone that would try to prove me wrong always had to make excuses later on(no, your $200_$300 dllr android device just didn't cut it my dude)

It really sucks sometimes for Android development. I want to know what Google got so wrong that they made the decisions they made in order to make people design other tools such as React Native, Cordova, Ionic, phonegapp, titanium, xamarin(which is shit imo) codename one and many others. With IOS i never considered going for something different than Native since the API just seemed so well designed and far superior to me from an architectural point of view.

Fast forward to 2018(almost 2019) adn Google had talks about flutter for a while and how they make it seem that they are fixing how they want people to design apps.

You see. I firmly believe that tech stacks work in 2 ways:

1 people love a stack so much they start to develop cool ADDITIONS to it(see the awesomeios repo) to expand on the standard libraries

2 people start to FIX a stack because the implementation is broken, lacking in functionality, hard to use by itself: see okhttp, legit all the Square libs, butterknife etc etc etc and etc

From this I can conclude 2 things: people love developing for IOS because the ecosystem is nice and dev friendly, and people like to develop for Android in spite of how Google manages their API. Seriously Android is a great OS and having apps that work awesomely in spite of how hard it is to create applications for said platform just shows a level of love and dedication that is unmatched.

This is why I find it hard, and even mean to call out on one product over the other. Despite the morals behind the 2 leading companies inferred from my post, the develpers are what makes the situation better or worse.

So just fuck it and develop and use for what you want.

Honorific mention to PHP and the php developer community which is a mixture of fixing and adding in spite of the ammount of hatred that such coolness gets from a lot of peeps :P

Oh and I got a couple of mobile contracts in the way, this is why I made this post.

And I still hate developing for Android even though I love Java.
