EDIT: devRant April Fools joke (2018)
-------------------------
Hey everyone! As some of you have already noticed, @trogus and I made a decision (based on the suggestion of some members of the community) to start transitioning all scores on the app to binary. We have started by making all user scores in our mobile apps and website (if you’re logged in) appear in binary. We think this makes the app more fun while remaining usable at the same time!

Please let us know what you think and happy binary-reading!

Lads, I will be real with you: some of you show absolute contempt to the actual academic study of the field.

In a previous rant from another ranter it was thrown up and about the question for finding a binary search implementation.

Asking a senior in the field of software engineering and computer science such question should be a simple answer, specifically depending on the type of job application in question. Specially if you are applying as a SENIOR.

I am tired of this strange self-learner mentality that those that have a degree or a deep grasp of these fundamental concepts are somewhat beneath you because you learned to push out a website using the New Boston tutorials on youtube. FOR every field THAT MATTERS a license or degree is hold in high regards.
"Oh I didn't go to school, shit is for suckers, but I learned how to chop people up and kinda fix it from some tutorials on youtube" <---- try that for a medical position.

"Nah it's cool, I can fix your breaks, learned how to do it by reading blogs on the internet" <--- maintenance shop

"Sure can write the controller processing code for that boing plane! Just got done with a low level tutorial on some websites! what can go wrong!"

(The same goes for military devices which in the past have actually killed mfkers in the U.S)

Just recently a series of people were sent to jail because of a bug in software. Industries NEED to make sure a mfker has aaaall of the bells and whistles needed for running and creating software.

During my masters degree, it fucking FASCINATED me how many mfkers were absolutely completely NEW to the concept of testing code, some of them with years in the field.

And I know what you are thinking "fuck you, I am fucking awesome" <--- I AM SURE YOU BLOODY WELL ARE but we live in a planet with billions of people and millions of them have fallen through the cracks into software related positions as well as complete degrees, the degree at LEAST has a SPECTACULAR barrier of entry during that intro to Algos and DS that a lot of bitches fail.

NOTE: NOT knowing the ABSTRACTIONS over the tools that we use WILL eventually bite you in the ASS because you do not fucking KNOW how these are implemented internally.

Why do you think compiler designers, kernel designers and embedded developers make the BANK they made? Because they don't know memory efficient ways of deploying a product with minimal overhead without proper data structures and algorithmic thinking? NOT EVERYTHING IS SHITTY WEB DEVELOPMENT

SO, if a mfker talks shit about a so called SENIOR for not knowing that the first mamase mamasa bloody simple as shit algorithm THROWN at you in the first 10 pages of an algo and ds book, then y'all should be offended at the mkfer saying that he is a SENIOR, because these SENIORS are the same mfkers that try to at one point in time teach other people.
These SENIORS are the same mfkers that left me a FUCKING HORRIBLE AND USELESS MESS OF SPAGHETTI CODE

Specially to most PHP developers (my main area) y'all would have been well motherfucking served in learning how not to forLoop the fuck out of tables consisting of over 50k interconnected records, WHAT THE FUCK

"LeaRniNG tHiS iS noT neeDed!!" yes IT fucking IS

being able to code a binary search (in that example) from scratch lets me know fucking EXACTLY how well your thought process is when facing a hard challenge, knowing the basemotherfucking case of a LinkedList will damn well make you understand WHAT is going on with your abstractions as to not fucking violate memory constraints, this-shit-is-important.

So, will your royal majesties at least for the sake of completeness look into a couple of very well made youtube or book tutorials concerning the topic?

You can code an entire website, fine as shit, you will get tested by my ass in terms of security and best practices, run these questions now, and it very motherfucking well be as efficient as I think it should be(I HIRE, NOT YOU, or your fucking blog posts concerning how much MY degree was not needed, oh and btw, MY degree is what made sure I was able to make SUCH decissions)

This will make a loooooooot of mfkers salty, don't worry, I will still accept you as an interview candidate, but if you think you are good enough without a degree, or better than me (has happened, told that to my face by a candidate) then get fucking ready to receive a question concerning: BASIC FUCKING COMPUTER SCIENCE TOPICS

* gays away into the night

I'm 20, and I consider myself to be as junior as they come. I only started programming seriously in June 2016,and since then, I've been doing mainly Android Work, and making my own servers and backends(using AWS/Firebase nd stuff).
For the first time in life, I was approached by a recruiter for a company on linkedIn. They "stumbled upon" my Github profile and wanted to see if I was interested in an internship opportunity. This company is an early stage start up, by that I mean a dude with an idea calling himself the CEO and a guy who "runs a tech blog" and only knows college level C programming (explaination follows).

So they want me to make the app for their startup. and for that, I ws first asked to solve a couple problems to prove my competence and a "technical interview" followed.
They gave me 3 questions, all textbook, GCD of 2 numbers, binary search and Adding an element to the linked List, code to be written on a piece of paper. As the position was that of an Android Developer, I assumed that Java should be the language of choice. Assumed because when I asked, the 'tech blogger' said, yeah whatever.
But wait, that ain't all, as soon as I was done, Mr. Blogger threw a fit, saying I shouldn't assume and that I must write it in C. I kept my cool (I'm not the most patient person), and wrote the whole thing in C.
He read it, and asked me what I've written and then told me how wrong I was to write 2 extra lines instead of recursion for GCD. I explained that with numbers large enough, we run the risk of getting a stackoverflow and it's best to apply non recursive solution if possible. He just heard stackoverflow and accused me of cheating. I should have left right then, but I don't know why, I apologized and again, in detail explained what was happening to this fucktard. Once this was done, He asked me how, if I had to, I'd use this exact code in my Android App. I told him that Id rather write this in Java/Kotlin since those are the languages native to Android apps. I also said that I'd export these as a Library and use JNI for the task. (I don't actually know how, I figured I can study if I have to).
Here's his reply, "WTF! We don't want to make the app in Java, we will use C (Yeh, not C++, C). and Don't use these fancy TOOLS like JNI or Kotlin in front of me, make a proper application."
By this I was clear that this guy is not fit to be technical lead and that I should leave. I said, "Sir, I don't know how, if even possible, can we make an Android App purely in C. I am sorry, but this job is not for me".
I got up and was about to leave the room, when we said, "Yeah okay, I was just testing you".
Yeah right, the guy's face looked like a howling monkey when I said Library for C, and It has been easier for me to explain code to my 10 year old cousin that this dumbfuck.
He then proceeded to ask me about my availability, and I said that I can at max to 15-20 hours a week since my college schedule is pretty tight. I asked me to get him a prototype in 2 months and also offered me a full time job after I graduate. (That'd be 2 years from now). I said thank you for the offer, but I am still not sure of I am the right person for this job.
He then said, "Oh you will be when I tell you your monthly stipend."
I stopped for a second, because, money.
And then he proceeded to say 2 words which made me walk out without saying a single word.
"One Thousand".

I live in India, 1000 INR translates to roughly $15. I made 25 times that by doing nothing more than add a web view to an activity and render a company's responsive website in it so it looks like an app.

If this wasn't enough, the recruiter later had the audacity to blame me for it and tell me how lucky I am to even get an offer "so good".
Fuck inexperienced assholes trying shit they don't understand and thinking that the other guy is shitsworth.

( rant || !rant ) && idiots
console.info( this.isLongRant );
console.warn( "contains strong language and wordpress" );

A friend of mine sent two of his "friends" to me because they wanted me to build a website for their new business (~idea).

So I had a meeting with them.

First of all they wanted me to have a look on the current (work in progress) site.
First impression of the frontend:
OH BOY!?

Well, imagine this:

- a 90s/2k background (dotted/pixelated cloud in baby-blueish as backgroud with repeat)

- the logo was made by the sister of one of the guys, it wasn't too bad, but badly aligned, asymmetrical

- some obvious $offTheShelfShopPlugin with $randomStockContent

- the fucking slider had a small loading bar to indicate changes, it appears like an hyperanxious child on ADHS

- below the logo TWO FUCKING GIF SPINNERS to indicate nothing else but how fucking brain amputated these two dudes are, including the dev who is responsible for adding this. (to this point, they only told me, that a webagency did the setup and some basic work on the site, more on that later)

- no styling concept at all, random fonts and stuff everywhere including default styles of the shop plugin.

- FUUUUUCK WTF wil come furtherin this meeting?

After seeing a pile of binary puke fisted out of a 60yo nonstop-intern who changed his jobtitle from dildo-traveling-salesman to fullstack-frontend-dev by wrinting it on a post-it-note, I imagined, there has to be something wrong with the backend as well.

Boy was I right!
Yes, you guessed it! A random Wordpress adminpanel login appeared! OH NO....
I really wanted to levae this meeting immediately.
I was not able to hold my disgust back and I told them right in their face, what a shit pile of nutty squirrel turds this current page is. And that Wordpress is not the right choice at all for a shop.

Then came the best part: They basically told me, that they terminated the previous contract with the webagency because they were too expensive (they are cheap, compared to others, I know people who know their prices) and that they wanted to create A BIG MARKETPKACE with multiple ressellers who can have their shop in their website. Something similar to FUCKING AMAZON. ON FUCKING WORDPRESS!?!?!?
They even asked me if I wanted to be their partner & developer and that they can't pay much at the moment until the marketplace starts to grow.

I more or less told them to go fuck themselves with a rusty pitchfork.

Me talking to a recruiter (even though I am not looking for a job)

Me: If I walk into an interview, and they ask me to reverse a binary tree for a frontend Reac or Vue position or something along those lines, I will end the call and/or walk away from it.

Him: I get similar feelings from other programmers, I don't quite understand why the notion is as common

Me: Because it is fucking useless, it servers no purpose to a dev to know about that when building frontends with react, I link my github profile, for which they can find advanced backend-frontend related projects, compiler and interpreter projects, plus the title I currently have at my workplace and a bunch of other shit, I am not interviewing for a teaching position at an institute, but an actual place of work, for which if they want to know about DS and A they can review my profile which has a repo of DS and A in about 5 different languages including plain C++. I do not need to be offended by such notions since they server no purpose on the frontend, and neither do other devs. If anything it should be a casual conversation during the interview, not a basis for employment.

Recruiter: .........thank you for explaining this to me, I am sure I can bring it up to the agencies doing the reviews and interviews. Are you still interested?

Me: Are they going to give me a coding assignment for a project or a bs question like what I mentioned?

Him: I don't know

Me: then I am not interested

Some fucker installed a keylogger on my Ubuntu laptop at home and registered it as a systemd service. From Wireshark, it's sending each keystroke to a server in France using irc. Tried accessing the server but the moron shut it down immediately. It's the last time am fucking installing code from prebuilt binaries. If I can't build it from source then fuck off your sniffing cunt. I was about to log in into a database from that machine.

UPDATE: I found the actual file sending the keystrokes but it's binary. Anyone know how I can decode a binary file?

Boy, this Monday mornig was crazy...
At 7 am, as I just left my flat, I received an ultra urgent email from the CEO of a company we exchanged the fileserver for, that the network shares are not available.

I instantly turned around, went back to my flat, fired up my HAL9000 supercomputer and connected remotely.
4 levels deep (PC => VPN => Remotedesktop => vSphere Client => VM) I felt like I was in the movie Inception and tried to figure out what happened.

I don't know why, but in the logs it said that the fileserver VM was down since 4am. Holy sithlord... why?

After restarting and the usual problems with Windows Network Names, everything was back online.

My special thanks go to Mr. Coffee, who is always a great companion during monday mornings, Mr. VPN, the great fellow who invented the VPN and last but not least "The Internet" for connecting me to a world of binary, where every idea finds a listener and where Ajit Pai can be memed without concequences.

FUCK YOU Ajit. Harlem Shake is so 2013.

My System Analysis professor wants to fail me because I refuse to store PDF files in the database in my project.

He wants me to store THE WHOLE BINARY FILE in the database instead of on the filesystem.

When I tried to explain why that would be bad, he interrupted me and began the "you think you know more than I do? I've been teaching this for X years" speech.

How do such people become professors?

Yesterday (or the day before that depending on your timezone and day-night schedule - this Friday) my OnePlus 6T arrived. After only 2 days of time between placing the order and actually getting the phone, quite impressive!

The DHL guy asked me upon receipt - is it the OnePlus 6T? - Yes it is!! - "An amazing device it is!", he said. And honestly.. he couldn't be more right.

I might be a bit biased on this because after all I did just spend €630 on this phone. But it feels so snappy, high quality, the 8GB of RAM is just.. it blows my mind. But I'm sure that the other reviews did this sort of jazz already.

The things that set this phone apart for me though were the following.

When I get a new phone or tablet, usually the first thing I do is rooting it. This one was no different, about an hour after receipt it was successfully rooted and loaded with Magisk. Currently I'm still in the phase of "getting to know the phone", wherein fuckups are usual. This time again being no different - I removed some apps and apparently did something to it that the search engines - both Google and DuckDuckGo - didn't quite like, as both of them would crash upon application launch. Me in full panic mode of course, desperately trying to find the stock ROM (which doesn't seem to be present in its usual form) or a new set of GApps (which didn't resolve the issue). OnePlus does seem to offer its OTA updates in zip archives though. So I downloaded its latest update (same as what was on the device) and applied it.

That's when the nerdgasm happened.

The "update" was simply a matter of going into the settings, tapping this and that and applying the update. No recovery, no unrooting, no nothing. The update just went like that despite the phone being rooted and just having had TWRP flashed to it. I always wanted this sort of thing, which even the Nexus couldn't offer - having the cake and eating it too. Being able to root the device and muck around with it while still being able to update the device timely without too many hurdles. This fucking thing does it!!!

That is to say, after my initial nerdgasm I did find that it bulldozed over my su binary (effectively unrooting the thing), custom emoji I've set (iOS 12 because fuck Google's most recent emoji set) and some other things. But those are easy to install back, much more so than it would've been to download a whole Android release and dirty flash it, as it was on the Nexus.

Other than that, battery life, dash charging (edit: on that topic, it does remain cool like a cucumber despite getting 15-20W of power jammed into it, quite impressive!), snappiness, the usual jazz.. eh, as I said earlier that's the usual reviewer stuff. But this feature of being able to upgrade the phone while it's modified, that's something which seems to be severely underrated by those.

Oh and during kernel builds, I couldn't quite get the source to work - probably due to my lack of experience with builds of Android kernels - but I did find that this phone actually exposes its kernel config through /proc/config.gz as it should. None of my MediaTek devices do this, so that's something that I found really appealing. Always nice to see when a manufacturer exposes this information to give you a stock sort of config that you can be rest assured will work configuration-wise. And it allows you to see what the stock kernel is actually built with, which again is really nice. I quite like this! It really encourages further development.

I love Linux, but its community can be so full of incompetent assholes..

Just now I asked in Freenode ##linux how to get the process ID of my current running process in bash. I got my answer - it's a shell built-in called "$$".

Then people start to nitpick some more - why do you need it? How is that different from an exit? - to which my response was.. well I know the whole idea behind exit codes, and I'd use it whenever possible, in all defined behavior that allows my program to terminate itself whenever it can. This pidfile however would be used to exit itself and provide diagnostic information whenever the program enters undefined behavior - a segfault in C language. Scenarios in which I don't have full control over the script's behavior anymore, such as the system entering an unworkable state where the system stalled, still got some binaries in RAM but the rootfs got unwritable, such as now - very helpfully, thanks HP! - when my laptop likely overheated and shat itself. I issued sudo reboot into it, but even that wouldn't issue properly anymore due to the /sbin/poweroff binary becoming inaccessible too. I had to issue a hard power cycle.. one of the few times in which I'm thankful to HP for actually causing shit like this, lol.

Point is, that undefined behavior is what I'm trying to mitigate against. I certainly can't let any files other than diagnostics remain in nonvolatile storage like that, especially when their state should be predictable in order to ensure good operation (like files expressing whether the script is already running or not, i.e. lock files).

Back to that IRC chat. Aside from the answer, I got ridicule from people who probably don't even know how to properly compile a kernel. Ubuntu users, overconfident scum. Sometimes I feel like I should ask questions in channels like #archlinux only, where such incompetency is ridiculed on its own.

Fuck Apple and its review system

So, this started in december. We wanted to publsih an app, after years of development.

Submit to review, and passes on the first try. Well, what do you know. We are on manual release option, so we can release together with the android counterpart. Well yes, but someone notices that the app name is not what was aggreed (App Name instead of AppName). Okay, should be easy, submit the same app, just the name changed. If it passed once, it will pass again, right? HAH

Rejected, because the description, why we use the device’s camera is too general. Well... its the purpose of the app... but whatever, i read the guidelines, okay, its actually documented with exapmles. BUT THEN WHY THE FUCK COULDNT YOU SAY THAT ON THE FIRST UPLOAD?

Whatever, fix it, new version, accepted, ready to release just in time.

It doesindeed roll out,but of course, we notice that the app has a giant issue, but only on specific phones. None of our test phones had this problem, but those who have, essentially cannot use our program. Nasty as it is, the fix is really easy, done in 5 minutes. Upload it asap, literally nothing changed from user point of view, except now it doesnt crash on said devices. Meanwhile 1 star reviews are arriving from these users - of course with all the right. Apple should allow this patch quickly, right? HAH

THE REAL BULLSHIT COMES NOW

With only config files changed, the same binary uploaded we get rejected? What now? Lets read it. “Metadata rejected, no need to upload new binary”.... oh fine only the store page is wrong? Easy. Read the message, what went wrong. “Referencing third party content is nit permitted on the app store” meaning that no android test device should be shown. Fine, your rules. They even send a picutre of the offending element. BUT ITS NOT EVEN ON THE STORE. THATS A SCREENSHOT OF THE APP. HOW IS THAT METADATA? I ask about this, and i get a reply, from either a bot, or a person who cant speak or read english, and only pasted a sample answer, repeating the previous message. WTF. Fine, i guess you are dumb, but since they stop replying to our queries, do the only sensible thing, re-record the offending tutorial video that actually contained an android device. This is about 2 weeks, after the first try to apply a simple patch to a broken app. And still, how did it pass the review 2 times?

Whatever, reupload again, play the waiting game for a week, when the promised average wait time is 2 days, they hit us with a message, that they want to know what patent we use in our apps core functionality. WTF WHY NOW? It didnt bother you for a month, let it release ti production and now you delay a simple patch for this? We send them what they know. Aaaaand they reply: sorry we need more time to review your app. FUUUUUUCKKK YOUUU. You are reviewing a PATCH with close to zero functional change!!! Then, this shit goes on, every week we ask about an ETA, always asking for patience... at the end it took another 3 weeks... so december 15 to jan 21 in total...

FOR. A. SINGLE. FUCKING. PATCH

Bottom line is what is infurating, apple cares that there is an android device in the tutorial video, but they dont care that a significant percentage of our users simply cannot use the app.

Im done

FUCK LINUX

now that I have your attention, and you’re probably angry, too, please, even if you don’t read this rant, never use code.org again. now, onto the rant…

god dammit, code.org sucks. I mean, anyone who created it or associates with it should, well, be considered a terrorist. they’re bombing students futures in computer science with false, useless, bullshit information. not to mention, their sponsors like bill gates, mark zuckerburg, and other rich asses, talk in a video about some boring ass shit that is hard to understand for anyone who doesn’t program, and not to mention, they use a fucking five dollar microphone. ear rape. even if you look at a textual version of it, then read the information on it, it’s practically useless because it's so terribly explained, and also useless. ironically enough, they focus on their animations more than their actual explinations, or their students for that matter. the fact that we had to encode a picture in binary, made me about 50% dumber, give or take a 0 or 1. then, we had to do it in hex, which wasn’t really much better, although more realistic I supposed. what's really the most depressing thing about this class is its application in the real world. I've learnt nothing whatsoever that will help me in the real world, or in computer science. I suppose there's two things that may be useful (that I already knew): hex, and that TCP doesn't lose packets. that's it. those two things. five seconds worth of knowledge from the first quarter of the year. the ideas just make me want to throw up. teaching the main ideas of computer science without actually teaching it? one of the teachers (probably a good one) enrolled her students in an online programming course just so they could understand, because the explanations are just so terrible. this is the only [high school] computer science course offered by code.org, and I signed up because it's an AP computer science class (tried to get into AP Java, the day I was supposed to take the test to get into an upper level class, I was told it didn't count as a tech credit). seriously, fuck code.org. it makes you dumber. their 'app lab' environment is pointless, just like everything else. the app lab is basically where you have a set of commands and have to make a dog bark() or a storm trooper miss() [and that's hell when they haven't introduced while loops yet]. the app lab is literally code.org going out of their way to make everything that their students are learning pointless in the real world. seriously, why can't we just use a <canvas> like an ACTUAL PROGRAMMER would do if they were to make a browser game, not use an app engine so slow it would be faster to update windows and android studio each time I run an 'app' in their 'environment'. their excuse is that the skills "transfer over" to the real world. BITCH! IF I DIDN'T KNOW JAVA, AND I WANTED TO MAKE A GAME IN JAVA, I'M NOT GOING TO LEARN PYTHON, THEN "TRANSFER" THE SKILLS I LEARNT, I'M GOING TO LEARN FUCKING JAVA. AND THAT GOES FOR EVER OTHER LANGUAGE, PROJECT, ETC.

I'm begging you code.org, stop, get help.

Interview:
Candidate claims being seasoned "senior".

Him: i don't know how the solve this
Me: you have to use binary search
Him: ahhaaa
Me: do you know binary search?

Turns out, some BT speakers can make low-battery sounds even when they are turned off.

I don't know if you guys caught this but everyone's binary scores are negative. The first bit is 1.

Yay

brain: ABSTRACTION ABSTRACTION ABSTRACTION too much ABSTRACTION!

me: jeez calm down a lil i just deployed a boilerplate ember web app with cli tools with next to nothing amount of 'my' code.

b: YES U SUCKER THAT'S WHAT WENT WRONG U DON'T KNOW SHIT ABOUT THE LIL STUFF THAT HAPPENS BEHIND THE SCENES THE FUCK MAN U CALL YOURSELF A CS STUDENT YOU CAN'T EVEN WRITE A COMPILER YET

m: sooo remember when we were studying logic gates and binary conversions and you sigkilled all my threads cuz it was 'boring'?

b: why yes why do you ask

m: WELL that's where we'll end up again if you don't stop nagging me about going down. Trust me, I KNOW how to starve you and you'll beg me to use Python again. You start making advanced data structures in C and the next thing you know you're writing assembly code 'just for fun'.
I have a hackathon coming right up and I have to use a framework or my team loses the advantage. Are we good?

b: well if you put it that way...BUT AFTER THAT YOU'RE TAKING ME TO AN ALGORITHM SESSION

m: *eerily stares at the dusty book in the corner*
you... have a deal

Me in school: Math? When do I need know those details? I can look them up and just code it.

Me in high school: Computer science is way too math-y. I want to code!

Me coding php: Just make it work.

Me coding typescript: Just make it work.

Me coding scala: Just make it ... what ... how do I make it work!?!

Me asking stackoverflow: How do I do X in scala some functional programming stuff in mind in order to keep immutability.

Somebody way smarter than I: "In scalaz, a function A => A is called an endomorphism and is a Monoid whose associative binary operation is function composition and whose identity is the identity function"

Me now: Fuck my old arrogant self.

I am a firmware developer with 4 years experience. C and sometimes assembly is my bread and butter.

Like 2 years ago, I was really interested to make a switch to application development. Got referred by my friend to her startup.

But I was a bit rusty with my data structures, high level languages and interpersonal skills.

The first question was to find the number of occurences for each word in a paragraph. The language choice was Java. But I was allowed to use C++ since it was the closest relative to Java that I knew.

And I started implementing a binary search tree from scratch and started inserting each tokenised word into it, wrote a traversal algorithm.

The interviewer, luckily, was a patient guy. After I completed my whole mess, he asked is it possible to do this in a slightly better way with constant time access without traversal.

I said yes, we can with a hash table but I dont know how to implement one. He replied I dont expect you to implement the hash table but see you use it. I asked him if I am allowed to used the standard library, for which he said ofcourse.

*facepalm*.

Finally I understood his expectation, referred cppreference.com and used an unordered_map.

Later there were some quesion on databases for which I tried my best to answer. And I frankly replied that I am not comfortable with JS frameworks as of now. Got rejected.

So the mistake is I never asked basic questions like what is the time complexity expects, if I was allowed to use standard library, didnt spend some extra time on studying stuffs needed for the domain switch and most importantly I panicked.

You wanna know what the fuck we did in our goddamn code.org class today, wait no, the last whole fucking week. YES OR NO QUESTIONS. I GET BINARY IS FUCKING 0'S AND 1'S. FOR GOD SAKES I KNOW BINARY. I EVEN KNOW FUCKING TERNARY. AND. YOU KNOW WHAT TEACHER ? EVERYONE ELSE COULD LEARN BINARY IN FIVE GODDAMN MINUTES. "Is code.org worthy of being kicked in the ass and tied up on a railroad when the trains coming?" Is a perfect binary question. This whole fucking class I feel like I'm in an english class for five year olds in spain. HEY TEACHER I DON'T CARE IF BILL GATES OR MARK SUCKERBURG OR BARAK OBAMA OR GODDAMN CHRIS BOSH SUPPORTS IT. ITS FOR THERE FUCKING REPUTATION. PEOPLE WITH HALF A BRAIN KNOW THESE PEOPLE DON'T GIVE A FUCK. THEY EACH HAVE HUNDREDS OF MILLIONS OR EVEN BILLIONS OF DOLLARS, BUT THEY ALL CHOSE TO USE A FIVE DOLLAR MIC JUST TO FUCK WITH US. EVERY TIME I WALK IN THAT CLASS I FEEL DEGRADED LIKE I'VE BEEN PUT BACK IN PRESCHOOL. THANK YOU TEACHER, I ALWAYS WANTED TO LEARN BINARY TO MAKE MY FUCKING SIMPLE JAVASCRIPT APP AS MY FINAL PROJECT FOR THE REST OF THE YEAR.

Senior dev at job interview didnt know what is binary search. I was interviewed by him.

Want to make someone's life a misery? Here's how.

Don't base your tech stack on any prior knowledge or what's relevant to the problem.

Instead design it around all the latest trends and badges you want to put on your resume because they're frequent key words on job postings.

Once your data goes in, you'll never get it out again. At best you'll be teased with little crumbs of data but never the whole.

I know, here's a genius idea, instead of putting data into a normal data base then using a cache, lets put it all into the cache and by the way it's a volatile cache.

Here's an idea. For something as simple as a single log lets make it use a queue that goes into a queue that goes into another queue that goes into another queue all of which are black boxes. No rhyme of reason, queues are all the rage.

Have you tried: Lets use a new fangled tangle, trust me it's safe, INSERT BIG NAME HERE uses it.

Finally it all gets flushed down into this subterranean cunt of a sewerage system and good luck getting it all out again. It's like hell except it's all shitty instead of all fiery.

All I want is to export one table, a simple log table with a few GB to CSV or heck whatever generic format it supports, that's it.

So I run the export table to file command and off it goes only less than a minute later for timeout commands to start piling up until it aborts. WTF. So then I set the most obvious timeout setting in the client, no change, then another timeout setting on the client, no change, then i try to put it in the client configuration file, no change, then I set the timeout on the export query, no change, then finally I bump the timeouts in the server config, no change, then I find someone has downloaded it from both tucows and apt, but they're using the tucows version so its real config is in /dev/database.xml (don't even ask). I increase that from seconds to a minute, it's still timing out after a minute.

In the end I have to make my own and this involves working out how to parse non-standard binary formatted data structures. It's the umpteenth time I have had to do this.

These aren't some no name solutions and it really terrifies me. All this is doing is taking some access logs, store them in one place then index by timestamp. These things are all meant to be blazing fast but grep is often faster. How the hell is such a trivial thing turned into a series of one nightmare after another? Things that should take a few minutes take days of screwing around. I don't have access logs any more because I can't access them anymore.

The terror of this isn't that it's so awful, it's that all the little kiddies doing all this jazz for the first time and using all these shit wipe buzzword driven approaches have no fucking clue it's not meant to be this difficult. I'm replacing entire tens of thousands to million line enterprise systems with a few hundred lines of code that's faster, more reliable and better in virtually every measurable way time and time again.

This is constant. It's not one offender, it's not one project, it's not one company, it's not one developer, it's the industry standard. It's all over open source software and all over dev shops. Everything is exponentially becoming more bloated and difficult than it needs to be. I'm seeing people pull up a hundred cloud instances for things that'll be happy at home with a few minutes to a week's optimisation efforts. Queries that are N*N and only take a few minutes to turn to LOG(N) but instead people renting out a fucking off huge ass SQL cluster instead that not only costs gobs of money but takes a ton of time maintaining and configuring which isn't going to be done right either.

I think most people are bullshitting when they say they have impostor syndrome but when the trend in technology is to make every fucking little trivial thing a thousand times more complex than it has to be I can see how they'd feel that way. There's so bloody much you need to do that you don't need to do these days that you either can't get anything done right or the smallest thing takes an age.

I have no idea why some people put up with some of these appliances. If you bought a dish washer that made washing dishes even harder than it was before you'd return it to the store.

Every time I see the terms enterprise, fast, big data, scalable, cloud or anything of the like I bang my head on the table. One of these days I'm going to lose my fucking tits.

Is this a bad way to traverse corners of a cube?
The objective is obvious from the context and I assume that programmers know how binary works.

So, I work in a game development studio, right?
We're trying to launch the title on as many platforms as reasonable, because as a social VR app we're kinda rowing upstream.
So far, Steam and Oculus have been fairly reasonable, if oddly broken and inconsistent.
Enter store 3.
Basically no in-game transaction support (our asking prompted them to *start* developing it. No, it's not very complete). No patch-update system (You want an update? Gotta download the whole fsckin' thing!). No beta-testing functionality for most of their stuff ("Just write the code like the example, it will work, trust us!"). No tools besides the buggy SDK (Wanna upload that new build? Say hello to this page in your web browser!).
So, in other words: Fun.

We've been trying to get actively launched for two months now. Keep in mind that the build has been up on Steam and Oculus for over a year and half a year (respectively), so the actual binary functionality is, presumably fine.

The best feedback we get back tends to be "Well, when we click the Launch button it crashes, so fail."
Meanwhile we're going back and forth, dealing with other-side-of-the-world timezone lag, trying to figure out what is so different from their machines as ours. Eventually we get them to start sending logs (and no, Windows Event logs are not sufficient for GAMES, where did you even get that idea????) except the logs indicate that the program is getting killed so terribly that the engine's built-in crash handler can't even kick in to generate memory dumps or even know it died.

All this boils down to today, where I get a screenshot of their latest attempt.

I just can't even right now.

Once again I have loads.

My best teachers were...

The contractor that taught me C#, ASP MVC and SQL Server. Dude was a legend, so calm and collected. He wanted to learn JQuery and Bootstrap so at the same time as teaching, he was learning from me. Such an inspirational person, to know your subordinates still have something to teach you. He also taught me a lot about working methodically and improving my pragmatism.

The other, in school I studied computing A-Level. 100% scored at least one of the exams... basically I knew my stuff.

But, as a kid, I didn’t know how to formulate my answers, or even string together coherent answers for the exams. This dude noticed, first thing he did was said “well you’re better at this bit than me, practice but you’ll be fine” (manually working out two’s complement binary of a number).

Second thing he did was say “you know what man, you know what you’re on about but nobody else is ever going to know that”.

He helped me on the subjects I wasn’t perfect on, then he helped me on formulating my answers correctly.

He also put up with my shit attendance, being a teenager with a motorcycle who thinks he knows it all, has its downsides.

As a result, I aced the hell out of that course, legendary grades and he got himself a bit of a bonus for it to use on his holiday. Everyone’s a winner.

Liam, Jason, if you guys are out there I owe you both thanks for making me the person I am today.

The worst, I’ve had too many to name... but it comes down to this:
- identify your students strengths and weaknesses, focus on the weaknesses
- identify your own and know when to ask for help yourself
- be patient, learning hurts.

You can always tell a passionate teacher from one who’s there for the paycheck.

(long post is long)
This one is for the .net folks. After evaluating the technology top to bottom and even reimplementing several examples I commonly use for smoke testing new technology, I'm just going to call it:

Blazor is the next Silverlight.

It's just beyond the pale in terms of being architecturally flawed, and yet they're rushing it out as hard as possible to coincide with the .Net 5 rebranding silo extravaganza. We are officially entering round 3 of "sacrifice .Net on the altar of enterprise comfort." Get excited.

Since we've arrived here, I can only assume the Asp.net Ajax fiasco is far enough in the past that a new generation of devs doesn't recall its inherent catastrophic weaknesses. The architecture was this:

1. Create a component as a "WebUserControl"
2. Any time a bound DOM operation occurs from user interaction, send a payload back to the server
3. The server runs the code to process the event; it spits back more HTML

Some client-side js then dutifully updates the UI by unceremoniously stuffing the markup into an element's innerHTML property like so much sausage.

If you understand that, you've adequately understood how Blazor works. There's some optimization like signalR WebSockets for update streaming (the first and only time most blazor devs will ever use WebSockets, I even see developers claiming that they're "using SignalR, Idserver4, gRPC, etc." because the template seeds it for them. The hubris.), but that's the gist. The astute viewer will have noticed a few things here, including the disconnect between repaints, inability to blend update operations and transitions, and the potential for absolutely obliterative, connection-volatile, abusive transactional logic flying back and forth to the server. It's the bring out your dead approach to seeing how much of your IT budget is dedicated to paying for bandwidth and CPU time.

Blazor goes a step further in the server-side render scenario and sends every DOM event it binds to the server for processing. These include millisecond-scale events like scroll, which, at least according to GitHub issues, devs are quickly realizing requires debouncing, though they aren't quite sure how to accomplish that. Since this immediately becomes an issue with tickets saying things like, "scroll event crater server, Ugg need help! You said Blazorclub good. Ugg believe, Ugg wants reparations!" the team chooses a great answer to many problems for the wrong reasons:

gRPC

For those who aren't familiar, gRPC has a substantial amount of compression primarily courtesy of a rather excellent binary format developed by Google. Who needs the Quickie Mart, or indeed a sound markup delivery and view strategy when you can compress the shit out of the payload and ignore the problem. (Shhh, I hear you back there, no spoilers. What will happen when even that compression ceases to cut it, indeed). One might look at all this inductive-reasoning-as-development and ask themselves, "butwai?!" The reason is that the server-side story is just a way to buy time to flesh out the even more fundamentally broken browser-side story. To explain that, we need a little perspective.

The relationship between Microsoft and it's enterprise customers is your typical mutually abusive co-dependent relationship. Microsoft goes through phases of tacit disinterest, where it virtually ignores them. And rightly so, the enterprise customers tend to be weaksauce, mono-platform, mono-language types who come to work, collect a paycheck, and go home. They want to suckle on the teat of the vendor that enables them to get a plug and play experience for delivering their internal systems.

And that's fine. But it's also dull; it's the spouse that lets themselves go, it's the girlfriend in the distracted boyfriend meme. Those aren't the people who keep your platform relevant and competitive. For Microsoft, that crowd has always been the exploratory end of the developer community: alt.net, and more recently, the dotnet core community (StackOverflow 2020's most loved platform, for the haters). Alt.net seeded every competitive advantage the dotnet ecosystem has, and dotnet core capitalized on. Like DI? You're welcome. Are you enjoying MVC? Your gratitude is understood. Cool serializers, gRPC/protobuff, 1st class APIs, metadata-driven clients, code generation, micro ORMs, etc., etc., et al. Dear enterpriseur, you are fucking welcome.

Anyways, b2blazor. So, the front end (Blazor WebAssembly) story begins with the average enterprise FOMO. When enterprises get FOMO, they start to Karen/Kevin super hard, slinging around money, privilege, premiere support tickets, etc. until Microsoft, the distracted boyfriend, eventually turns back and says, "sorry babe, wut was that?" You know, shit like managers unironically looking at cloud reps and demanding to know if "you can handle our load!" Meanwhile, any actual engineer hides under the table facepalming and trying not to die from embarrassment.

Let's try this.

In the project I'm working there is an strict rule : NO COMMENTS!!!

I mean wth, the times I've spend hours trying to understand the crappy legacy code in VB.Net that has been there almost decades, that wouldn't happen with comments, I know i know there are some supernatural developers that think in binary and their eyes work as compilers, but I'm not like that, so seriously go to hell.

P.S. Of course I follow that rule, after all, my code is so damn perfect that even a baby can understand it.

jk

Well I feel like an idiot thanks to my IT teacher. This guy, this fucking guy thinks that we’re seeing computer for the first time. He’s literally saying “You see this black bar on the bottom? That’s taskbar.”. It’s like he’s teaching 7 years old childs 😤
But the worst part is my class mated don’t know such basics! They don’t know how binary code works, what is motherboard, how to login to school domain on Windows.

But on the flip side, they look at me like at the God 😏

If you're going to build an open source command line tool, please for fuck sake publish the Linux x64 artifact to the world. I don't want to waste half my day setting up a box just to compile your project.

I know you build the artifact, I see it in your public CI system. The badge at the top of your GitHub repo even says it's good today. So seriously, why can't you just publish that binary to S3 so I don't have to waste my day ranting.

The saddest and funniest side of our industry is (atleast in India): someone works hard and makes it to the best colleges, do great projects on AI, ML; get a good score on Leetcode, codechef; gets a job in FAANG-like companies...

Changes colors in CSS and texts in HTML.

And, why is there so much emphasis on Data Structures and Algorithms? I mean, a little bit is fine, but why get obsessed with it when you never write algorithms in production code?

Now, don't tell me that, we use libraries and we should know what we are doing, no, we don't use algorithms even in libraries.

Now, before you tell me that MySQL uses B-tree for maintaining indexes, you really don't need to solve tricky questions to be able to understand how a B-tree works.

It's just absurd.

I know how to little bit on how design scalable systems.
I know how to write good code that is both modular and extensible.
I know how to mentor interns and turn them into employees.
I know how to mentor junior engineers (freshers) and help them get started.
Heck I can even invert a binary tree.

But some FAANG company would reject me because I cannot solve a very tricky dynamic programming question.

Disclaimer: I hold no grudges or prejudices toward [CENSORED] company. I love the concept of the business model and the perks they pay their employees. Unfortunately, the company is very petty, and negligence is the core of the management. I got into an interview for the position, of Senior Software Engineer, and the interview wouldn't take place if wasn't for me to follow up with the person in charge countless times a day. The Vice President of Engineering was the most confused person ever encountered. Instead of asking challenging questions that plausibly could explain and portray how well I can manage a team, the methodology of working with various technology, and my problem-solving skills. They asked me questions that possibly indicated they don't even know what they need or questions that can easily get from a Google Search. I was given 40 hours to build a demo application whereby I had to send them a copy of the source code and the binary file. The person who contacted me don't even bother with what I told her that it is not a good practice to place the binary in cloud storage (Google Drive, OneDrive, etc) and I request extra time to complete the demo application. Since I got the requirement to hand them the repository of the codebase, it is common practice to place the binary in the release section in the Git Platform (Jire, Azure DevOps, Github, Gitlab, etc). Which he surprisingly doesn't know what that is. There's the API key I place locally in .env hidden from the codebase (it's not good practice to place credentials in the codebase), I got a request that not only subscript to an API is necessary but I have to place them in the codebase. I succeed to pass the source code on time with the quality of 40 hours, I told him that I could have done it better, clearer and cleaner if I was given more grace of time. (Because they are not the only company asking me to write a demo application prior to the assessment. Extra grace was I needed)

So long story short, I asked him how is it working in a [CENSORED] company during my turn to ask questions. I got told that the "environment is friendly, diverse". But with utmost curiosity, I contacted several former employees (Software Engineer) on LinkedIn, and I got told that the company has high turnover, despises diversity the nepotism is intense. Most of the favours are done based on how well you create an illusion of you working for them and being close to the upper management. I request shreds of evidence from those former employees to substantiate what they told me. Seeing the pieces of evidence of how they manage the projects, their method of communication, and how biased the upper management actually is led me to withdraw from continuing my application. Honestly, I wouldn't want to work for a company where the majority can't communicate.

Is the way people solve problems intrinsic to the native language they learned growing up? Can the shape of our thoughts be optimal for solving certain kinds of problems? Like sentence structure, grammar, etc.

If the pattern of thoughts a language promotes can help us solve problems. Then is there a spoken language that can help promote solving computer science problems?

I know I have to work to think differently to program in different styles of programming. I wonder if we can learn from different spoken languages patterns of logic that are applicable to engineering.

Mathematics, while not a spoken language, has helped me re-frame things in programming. I think programming has also helped in other areas. Like using binary search to find the end of a pipe in the ground.

If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:

This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...

Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?

Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...

All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).

So what other options are there for making plugins in Go?

There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...

Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...

Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.

Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.

As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...

Have a good night(/day)!

Major rant incoming. Before I start ranting I’ll say that I totally respect my professor’s past. He worked on some really impressive major developments for the military and other companies a long time ago. Was made an engineering fellow at Raytheon for some GPS software he developed (or lead a team on I should say) and ended up dropping fellowship because of his health. But I’m FUCKING sick of it. So fucking fed up with my professor. This class is “Data Structures in C++” and keep in mind that I’ve been programming in C++ for almost 10 years with it being my primary and first language in OOP.

Throughout this entire class, the teacher has been making huge mistakes by saying things that aren’t right or just simply not knowing how to teach such as telling the students that “int& varOne = varTwo” was an address getting put into a variable until I corrected him about it being a reference and he proceeded to skip all reference slides or steps through sorting algorithms that are wrong or he doesn’t remember how to do it and saying, “So then it gets to this part and....it uh....does that and gets this value and so that’s how you do it *doesnt do rest of it and skips slide*”.

First presentation I did on doubly linked lists. I decided to go above and beyond and write my own code that had a menu to add, insert at position n, delete, print, etc for a doubly linked list. When I go to pull out my code he tells me that I didn’t say anything about a doubly linked list’s tail and head nodes each have a pointer pointing to null and so I was getting docked points. I told him I did actually say it and another classmate spoke up and said “Ya” and he cuts off saying, “No you didn’t”. To which I started to say I’ll show you my slides but he cut me off mid sentence and just yelled, “Nope!”. He docked me 20% and gave me a B- because of that. I had 1 slide where I had a bullet point mentioning it and 2 slides with visual models showing that the head node’s previousNode* and the tail node’s nextNode* pointed to null.

Another classmate that’s never coded in his life had screenshots of code from online (literally all his slides were a screenshot of the next part of code until it finished implementing a binary search tree) and literally read the code line by line, “class node, node pointer node, ......for int i equals zero, i is less than tree dot length er length of tree that is, um i plus plus.....”
Professor yelled at him like 4 times about reading directly from slide and not saying what the code does and he would reply with, “Yes sir” and then continue to read again because there was nothing else he could do.

Ya, he got the same grade as me.

Today I had my second and final presentation. I did it on “Separate Chaining”, a hashing collision resolution. This time I said fuck writing my own code, he didn’t give two shits last time when everyone else just screenshot online example code but me so I decided I’d focus on the PowerPoint and amp it up with animations on models I made with the shapes in PowerPoint. Get 2 slides in and he goes,
Prof: Stop! Go back one slide.
Me: Uh alright, *click*
(Slide showing the 3 collision resolutions: Open Addressing, Separate Chaining, and Re-Hashing)
Prof: Aren’t you forgetting something?
Me: ....Not that I know of sir
Prof: I see Open addressing, also called Open Hashing, but where’s Closed Hashing?
Me: I believe that’s what Seperate Chaining is sir
Prof: No
Me: I’m pretty sure it is
*Class nods and agrees*
Prof: Oh never mind, I didn’t see it right

Get another 4 slides in before:
Prof: Stop! Go back one slide
Me: .......alright *click*
(Professor loses train of thought? Doesn’t mention anything about this slide)
Prof: I er....um, I don’t understand why you decided not to mention the other, er, other types of Chaining. I thought you were going to back on that slide with all the squares (model of hash table with animations moving things around to visualize inserting a value with a collision that I spent hours on) but you didn’t.
(I haven’t finished the second half of my presentation yet you fuck! What if I had it there?)
Me: I never saw anything on any other types of Chaining professor
Prof: I’m pretty sure there’s one that I think combines Open Addressing and Separate Chaining
Me: That doesn’t make sense sir. *explanation why* I did a lot of research and I never saw any other.
Prof: There are, you should have included them.
(I check after I finish. Google comes up with no other Chaining collision resolution)

He docks me 20% and gives me a B- AGAIN! Both presentation grades have feedback saying, “MrCush, I won’t go into the issues we discussed but overall not bad”.

Thanks for being so specific on a whole 20% deduction prick! Oh wait, is it because you don’t have specifics?
Bye 3.8 GPA

Is it me or does he have something against me?

So, the last days I saw a few posts here about binary clocks. Somehow I wasn't able to read them, until I read a comment they had to be read horizontally.

As far as I know binary clocks are supposed to be read vertically. Am I missing something? 🤔

I know this sounds odd, but I really find algorithms things of delightful beauty.

A creative solution to some very deceptively complex problems.

Sure, some implementations aren't the best, but seeing them after just makes me appreciate the time and effort that must have gone into designing things like Merge Sort, Binary Search, Greedy Algorithms, BST, and Dijkstra's Algorithm.

So! If your code is unoptimal, looks terrible, or is a sheer abomination, take a moment to appreciate the little piece of art you've made before you go and make it better.

In the 90s most people had touched grass, but few touched a computer.

In the 2090s most people will have touched a computer, but not grass.

But at least we'll have fully sentient dildos armed with laser guns to mildly stimulate our mandatory attached cyber-clits, or alternatively annihilate thought criminals.

In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.

The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.

Whats left after filtering, is strictly the primes.

I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.

I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).

Well, imagine my surprise when I had zero false positives.

Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.

My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.

I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.

I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.

The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.

If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.

//First rant

So I've been working trying to get a file exporter for a binary file format mostly reverse engineered - 2001 Super Monkey Ball 2 (GameCube) if anyone's interested.

Everything works fine, goals show up in the right places, wormholes work as intended, etc. That is everything, except every single level you create will be invisible, or crash (Depending on which version of Dolphin emu you use).

This happens whenever trying to specify object names for 3D objects. I checked, all the many offsets seem correct, Object names are correct. Tried both null terminated strings and fixed 80 character strings - nothing.

Some other guy also made an exporter that works, however the code is an absolute mess - basically unreadable. It also lacks some newer parts of the file spec, which is the main reason as to why I'm rewriting it.

And as I'm working with an almost entirely unheard of file format, there are few people to go to for help. The 2 I know who are also familiar with the LZ file format have no idea either...

Sigh.

Hopefully, you already know that the company controlled by the alledged reptiloid subhuman and olimpic testicle juggler formerly known as Mister Zuck My Tits is not to be trusted.

But as is always the case in this bitch, I've been forced into cowjizz flooded swamps' worth of stinking shit platforms for the sake of avoiding isolation.

And so, I've just found yet another way in which Facebook **THUNDERSTRIKE** ... the company, not the geriatric ward, is one of the CROWN ACHIEVEMENTS of human civilization.

Let me tell you something: some people are fucking broke. Hell, some people sleep on the streets, live on scraps, and willingly engage in acts of public defecation when provoked. But I'm not even talking about them no, just plain *broke*.

And so imagine being that guy who doesn't really use his phone much, except maybe for sharing cat pictures with mom because that's what being an absolute chad is all about. You don't get a new phone, because money is a __little__ bit tight. But THEN...

"Still you breathe?!" you exclaim, suddenly transformed into a heroic, sexy moustachoed arquebusier "After I'm done ~OILING~ my VICTORIOUS CHEST, I *shall* bestow DEATH uppon you!".

But as you rip open your shirt to apply sensual oiling to your marvellous frontal assets, your nemesis reveals it's portentous Portugal: "this new version of Android... " he gasps as he perishes "is incompatible with your device... "

"Ughh! Sacrebleu!" you shriek out in pain, realizing that you are now unable to ACCESS THE FUCKING DATA THAT IS IN YOUR OWN FUCKING HARDWARE BECAUSE OF A STUPID FORCED BINARY INCOMPATIBILITY.

That's right. Now even if I *do* get a new phone, I can't do shit about losing all of the family memes. And contacts and all of that shit, but the stickers are more important. A minor inconvenience, yes, and it didn't need all of this preamble but I was doing the dramatic fight scene bit inside my head as I was writing and I got into it.

Because the only documented way to transfer all of that data is to OPEN THE APPLICATION and scan some code, but everytime I go to do that, IT TELLS ME I NEED TO UPDATE. And every time I GO TO UPDATE, it says that MY PHONE is TOO FUCKING OLD!! AAAAAAAGHGHGHGHGHGHGHG!!!!

And you too, might be a dashing french man from centuries past, with both balls and tits down to your fucking knees, folding your arms in a position that exhumes smugness in a disgustingly irreverent and self-aggrandizing way, looking at me as a mere plebeian who cannot wrap his head around the mystical art of interacting with Google's black deuce box.

And you would be somewhat right in your judgement! But just having to fiddle about with these fucking pocket Elmo screens is such a traumatic experience for me that I'd rather lose my stickers.

[ADBREAK] Are you a debonair victorian undercover butt pirate, taking unparalleled care of your Falstaffian, highfalutin poils pubiens? Need your "sword" sharpened, as you browse through the pages of this magnanimous lexicon? Would you rather allocate final death to your coworkers than learn one more synonym for sonorous, supercilious and pontifical?

This is gonna get someone illogically upset, but idc about that.

I know it's ignorance of semantics but I'm tired of propagated ignorance changing the meaning of things.

Non-binary is NOT a legitimate term for whatever 'gender' you are!

I get what *whoever-started-it* was going for, but it's NOT valid. If you want to say that youre not male or female, fine... just don't abuse binary systems to do it. Just say youre non-bool/anti-boolean or identify with one of the, apparently 50, shades of gray.

I keep getting into logical loops to nowhere about this nonsense. No one is even defining what's supposed to be the 1 vs the 0. Which then makes me think '1 must be male... genitalia=1 in many ways...' which then sources back to the historic validity of males vs undervalued/less than human interpretations of females...

Then <brake>.
Ofc these people aren't going into the historical significance... they don't even realise how binary works! Ofc they'd have no clue that all 0s= no data... and 0s only have significance when viewed in placement to the 1s.

Let's all start using proper terminologies, like non-boolean. Maybe i can start a trend by paying people pennies to learn/teach wtf a boolean value is, and that binary can represent anything. With proper encoding the array is limitless... so being binary is actually a giant spectrum... therefore makes no sense to be "non-binary".

Ok... im done. It had to be said.

Who wants to start identifying as non, or educating wtf is, boolean with me???

So, when I was like 18 I made an app for a guy who stole a phone book database in paper and was paying people to pass it to access.
He asked me a program to make it easier to add data, he was paying people to do it one by one to an access db.
So I made that and a module to join all the dbs and check for existing ones (there was no way to join access db back then).
When he told me he didn't want it anymore...
So I deleted the sorce code and gave the binary to an uncle to use as a phone book for work.
Two weeks latter the guy called because he didn't know how to join the dbs. Well the source wasn't lost... I just deleted it and told him that if he had paid my software would take care of it...

So my data structure's exam's result came and i got scored 57.5 out of 80. My classmates who barely know anything about C scored way more than me. I am so embarrassed at myself but i gave the right answers in exam. My score in the exams before was 39/40 and 38.5/40. All my hardwork failed because it was a so called THEORY exam where there was only 2 small questions of writing algos but all others were just like "describe pre-order traversal of a binary tree" or "write the difference between a tree and a graph?define adjacent node, path and complete graph"...
When will this fuckery end?

Hi everyone. Thanks in advance. Although this might sound stupid, keep in mind that someone requested the following:

Someone on discord asked me to make an aim assist program for a game. I thought it might be a fun way to introduce myself to memory writing and binary trees. I accepted the request and started researching. I'm using C++ and I have some options if I need to switch programming languages. Honestly I don't know where to start, but I thought finding a color on the screen using ML or something then moving the mouse position might work. This is also one of my close friends so he wouldn't be too sad/mad if I failed the request.

Spend hours debugging a python script because tests fail. Turns out ftp (the unix binary) adds CR bytes to every byte in a .gz file that looks like a LF on upload (in test setup). Client and server are both linux. 😭

Yes i know switch to binary mode (that fixed it - why not default??). But still WHY CR? Didn't ask for it. No windows in sight.

by simply making the bias random on the second input for a two bit binary input during activation calculation, it's possible to train a neural net to calculate the XOR function in one layer.

I know for a fact. I just did it.

My university had a Programming Fundamentals course in the first semester and we got assigned this grumpy lady who demanded respect and would always claim she was the best at programming among her colleagues, had an obnoxiously snobbish tone and had a habit of forcing unneeded nonsensical sarcasm everytime one of us stepped up to ask her a question.

She taught C++ and I'm not saying she didn't know her stuff or anything; I respected her regardless (because she was my teacher), but she would mix up C classes in and insist that that was the right way to do it and had no consistent programming style.

Once she got so fed up with our class that just to prove her point that we're all dumb and worthless (she hated us a lot, yeah) that she started explaining binary trees and recursion out of the blue and gave us assignments for them... even though they weren't going to be covered that week. It soon became a shitfest, to be honest.

But on the plus side, because I didn't wanna listen to her lectures I pulled two all-nighters and covered the semester's worth of C++ and started napping in a corner in her class. She never had personal beef with me so I was thankful for that but her being the way she was helped me learn C++ with more motivation and vigor than I normally would have and also let me earn some change because my classmates couldn't understand her classes and wanted me to explain whatever she covered.

Hey fellow ranters...quiz time!! What is 9 times F?

research 10.09.2024

I successfully wrote a model verifier for xor. So now I know it is in fact working, and the thing is doing what was previously deemed impossible, calculating xor on a single hidden layer.

Also made it generalized, so I can verify it for any type of binary function.

The next step would be to see if I can either train for combinations of logical operators (or+xor, and+not, or+not, xor+and+..., etc) or chain the verifiers.

If I can it means I can train models that perform combinations of logical operations with only one hidden layer.

Also wrote a version that can sum a binary vector every time but I still have
to write a verification table for that.

If chaining verifiers or training a model to perform compound functions of multiple operations is possible, I want to see about writing models that can do neighborhood max pooling themselves in the hidden layer, or other nontrivial operations.

Lastly I need to adapt the algorithm to work with values other than binary, so that means divorcing the clamp function from the entire system. In fact I want to turn the clamp and activation into a type of bias, so a network
that can learn to do binary operations can also automatically learn to do non-binary functions as well.

Math question time!

Okay so I had this idea and I'm looking for anyone who has a better grasp of math than me.

What if instead of searching for prime factors we searched for a number above p?
One with a certain special property. BEAR WITH ME. I know I make these posts a lot and I'm a bit of a shitposter, but I'm being genuine here.

Take this cherry picked number, 697 for example.

It's factors are 17, and 41. It's trivial but just for demonstration.

If we represented it's factors as a bit string, where each bit represents the index that factor occurs at in a list of primes, it looks like this

1000001000000

When converted back to an integer that number becomes 4160, which we will call f.

And if we do 4160/(2**n) until the result returns
a fractional component, then N in this case will be 7.

And 7 is the index of our lowest factor 17 (lets call it A, and our highest factor we'll call B) in our primes list.

So the problem is changed from finding a factorization of p, to finding an algorithm that allows you to convert p into f. Once you have f it's a matter of converting it to binary, looking up the indexes of all bits set to 1, and finding the values of those indexes in the list of primes.

I'm working on doing that and if anyone has any insights I'm all ears.

At an interview, interviewer keep on hitting me with theoretical questions, why python don't have switch cases, what is default sorting in java etc... I told him I don't bother about theory, then this conversation happened.
I(Interviewer)
I: do you know time complexities?
me: Yes
I: okay, tell me a few sorting or searching algorithms which have logarithmic complexity?
me: binary search (with loud and confident voice)
I: he told, in worst case it will have O(n) tell me any other
me: *thinking*
I: what are you thinking? what is time complexity of merge sort
me: O(nlogn)
i: it's logarithmic....

Does anyone by any chance know how to pipe binary data out of Python? I digged through the first 10 pages of Google, but none of that did what I needed. I know how to pipe things between subprocesses, but not to the stdout of Python.

The rear ducking continues. We've built a reliable translator in the dumbest fucking way possible, it's just lovely. I simply reused the structure for feeding data to the VM assembler, an array of arrays, where there's one array of (ins [args]) per node in the parse tree.

It's nice because nodes can be solved out of order without affecting the actual sequence in which the instructions are output. And if one statement (node) equals multiple instructions, you just push multiple entries to the corresponding array, or push nothing if you need to output nothing. Easy as goblin pie.

This is enough to convert an input language to the assembly-like intermediate representation we use for the virtual machine. So then there's doing it backwards: walk the same array of arrays, and map those virtual instructions to a physical architechture. I guess I could do the encoding to native binary myself, it'd certainly be interesting to try, but I'm burnt-out already so I'll just use fasm for now.

Initial test: wrote a test program in my own stupid language, ran the translator, dump output to file, assemble that with fasm, run with r2 -d.

Crashes? No.
Runs fine? Yes and no.

For fuck's sake, I don't have syscalls. Mainly because the VM doesn't have an operating system, lmao. I was testing virtual programs by just freezing state, terminating, then dumping the fucking registers and stack to the console, we have no I/O to speak of. Not even a real 'exit', VM handles that by reading a return value every step like a mentally damaged son of a bitch.

So anyway, I manually paste the linux mambo, you know:

mov rax,60
mov rdi,0
syscall

And NOW our program can end execution without crashing.
Okay then, so does the test code work correctly?

** DRUM ROLL **

Yes.

Ladies and gentlemen, mother fucking PESO is now a compiled language, and going forward I will be expectantly receiving your marriage proposals for reviewing. Oh, but not so fast, we still need a frontend...

Well, we'll handle that in the next few days. I'm just glad to be *nearly* finished with this fucking compiler, I want nothing to do with anything else ever, but we know that's not going to happen, so Lord please end my pain.

No sponsor as this rant has been paid for by tax evasion.

I know it's not really related to development, but I got in a discussion on twitter and one dude tweeted "in science, 1 isn't 1"
And so I was like "mate what? science is highly dependent on math and in math, 1 is kinda always worth math"

And this this girl comes in and just says:
"it's not true that 1 is always 1 because there's binary code as well"

And was was like totally astonished, like, have you even studied something? 1b = 1d = 1x and it's always 1 in whatever base!
(she even says she's some sort of engineer in her bio)

I 2 know binary

Okay, lemme be honest today...
So, I don't know HOW TO CODE IN BINARY.
Looking for some tutorial on Binary coding.
Pleaaasssseeeee...

I guess I'll just die.

Using unity for a commission project:
Have a CCG-like setup, the cards inherit from Scriptable object, need to serialize a card inventory for the sake of persistence.
Attempt 1: XML serialization: get fucked, can't serialize dictionaries (what the hell)
Attempt 2: using data representation of the dictionary contents: get fucked, can't serialize Scriptable objects because they have to be handled by the engine...
Well okay, what if I use a Scriptable object to keep a persistent dictionary?
Attempt 3: Scriptable object with dictionary: get fucked, the dictionary didn't persist
Well now I'm starting to lose it, I've tried so many things, XML, Binary and JSon serialization, Scriptable objects, data representations, I'm really running out of ideas. I can only think of one more option: throw the Card objects into a Resources folder, an build a set of comma delimited strings to serialize. This is stupid.

Fuck Unity. Shit like this is why I'm making my own engine. Every week I find some new peeve, some new way that unity is full of redundancy and poor design, architectural flaws and workflow deficiencies. I don't know how much more of this I can take.

And here it comes bois, the famous Monday Morning Mumbling is back, for everyone's pleasure.

Do you remember your uni years, when you had wonderful coding lessons, and you learned sick languages ?

I do aswell, since I'm still in uni.

But why, WHY, IN ALL OF GOD THOUGHTS, DO I STILL HAVE TO TAKE MATHS LESSONS ?

It's my fourth fucking uni year, and I'm still supposed to deal with math lessons which are about what I learned 6 years ago. And guess what ? I still failed the test since I fucking don't understand a single shit in maths.

"Uuuuh if yu wan tu derivate a function u hav to multiply ur derivated function basic expression with the derivate itself lul xDDD so funi"

FUCK OFF DUDES I DON'T GIVE A SINGLE SICK BIRD SHIT ABOUT MATHS. I WASTED THREE YEARS OF MY LIFE LEARNING ABOUT BINARY TREES, MATHEMATICALS WAYS OF SPILLING YOUR CEREAL BOWL WHEN YOU HAVE TO LEAVE IN FIVE MINUTES, NUMERIC WAY OF OPTIMIZE YOUR SINK SPACE WHEN YOU'RE TOO LAZY TO DO THE DISHES, JUST LET ME FUCKING WRITE CODE INSTEAD OF ANNOYING ME WITH UNEXPLAINABLE MATHS SHIT NOW !

I know maths are important, okay ? But I'm so fucking tired of learning this shit again and again and still failing those shitty tests where they only give you maths problems without any other goal than messing with your grades.

Fuck this shit I'm pissed off on so many levels, I wasted tons of money on a private school to enhance my résumé history, and now I'm stuck with some strange "f'(x)" boi that will ruin my year.

RT's appreciated, if you recognised yourself in this story, don't forget to send some biscuits to my postal address.

TL;DR : Why wasting your time on theoritical lessons when you could use your time to learn new dynamic technos, like C++98 ?

What is the best source for learning x86 asm and binary exploitation? Got any recommendations for me? (books?) I already know godbolt.org I'd also be interested in optimisation.

You know most coding languages (Except binary) if I am not mistaken had to be coded. That's something to sink you teeth into (;

Hello to everyone in this platform. I am a college student who wants to become a software developer from the first class of the high school. Unfortunately, in my country it isn't possible that both study to university exam and learn other stuff(Actually you can if you sleep 6 hours and stay on home every time without a social life). Now I'm glad that I have entered one of the best college in my country, but the information I learn in the college is not enough for me. Because of that I am looking for a good algorithms book that teaches the logic of common algorithms(like binary search, DFS, BFS and the things like that). I know I can learn them on the internet ofc, but currently I have to spend a lot of time on computer so I want to a book version of these information. Sorry for this long post. All book recommendations are appreciated :)

having a DSA interview in 2 days, any suggestions on how/what to prepare?

its been years since i tried solving coding problems with anything apart from strings or arrays( and that too the one we use in dev, like writing a function to convert string to uppercase, that's all i remember)

There are a million algorithms: knapsac, djikstra, DFS BFS, bellman ford, TRIE, BST, quick sort, merge sort, insertion , binary search... these are some buzz words i could remember from my early college days, 6 years ago. I was able to understand and learn them at that time, but now i know shit about them :/

How to go with all of these in 48 hours?

Today I'm starting interviewcamp.io. I graduated from a 4-year university in California with a degree in computer engineering and have almost 3 years of work experience, but my god I am terrible at algorithms.

Big O (time and space complexity), recursion, Binary Search Trees, reversing a fucking linked list, etc. I need the boost and I hope the $250 a year for the material will help me get at least a $5k increase in salary when jumping to another company after the whole pandemic (or get a raise at my current job).

If anyone has any experience with them let me know. So far I'm 2 hours in and it is nice so far.
