*Now that's what I call a Hacker*
MOTHER OF ALL AUTOMATIONS
This seems a long post. but you will definitely +1 the post after reading this.
xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown... If something - anything - requires more than 90 seconds of his time, he writes a script to automate that.
xxx: So we're sitting here, looking through his, uhm, "legacy"
xxx: You're gonna love this
xxx: smack-my-bitch-up.sh - sends a text message "late at work" to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login.
xxx: kumar-asshole.sh - scans the inbox for emails from "Kumar" (a DBA at our clients). Looks for keywords like "help", "trouble", "sorry" etc. If keywords are found - the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply "no worries mate, be careful next time".
xxx: hangover.sh - another cron-job that is set to specific dates. Sends automated emails like "not feeling well/gonna work from home" etc. Adds a random "reason" from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am.
xxx: (and the oscar goes to) fuckingcoffee.sh - this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.
xxx: holy sh*t I'm keeping those

Last year I got an Acer notebook from a guy that stated that "it isn't working". "Okay" I thought, let's boot it up.
> Screen turns on, no splash screen, no hard drive activity
> Well fuck
> Tries to enter BIOS, nothing
> Openes case to reset CMOS
> Nothing
> Okay I think I need to flash a new BIOS
> Acer support site
> "Download the exe to flash the BIOS"
> What
> Spend two hours researching
> Find out that you can flash via USB and by pressing a key combination
> Extract the BIOS binary from the exe file
> Flash it on the notebook
> Splash screen and working BIOS
> Yay!!!
> No bootable devices found
> Fuck
> Connects hdd with test bench
> Completely fucking dead
> WTF
> Order a new hard drive
> 3 days later
> Install hdd
> Install Windows
> Finally working
WTF did you do to this notebook to not only mechanically break your hdd but also fuck up the BIOS completely??!!13 -
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.10 -
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.11 -
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.7 -
So, the uni hires a new CS lecturer. He is teaching 230, the second CS class in the CS major. Two weeks into the semester, he walks in and proceeds to do his usual fumbling around on the computer (with the projector on).
Then, he goes to his Google Drive, which is empty mostly, and tells us that he accidentally wrote a program that erased his entire hard drive and his internet storage drives (Google, box, etc.)...
I mean, way to build credibility, guy... Then he tells us that he has a backup of everything 500 miles away, where he moved from. He also says that he only knows C (we only had formally learned Java so far), but hasn't actually coded (correction: typed!) in 20+ years, because he had someone do that for him and he has been learning Java over the past two weeks.
The rest of the semester followed as expected: he never had any lecture material and would ramble for an hour. Every class, he would pull up a new .java file and type code that rarely ran and he had no debugging skills. We would spend 15 minutes trying to help him with syntax issues—namely (), ;— to get his program running and then there would be a logic issue, in data structures.
He knew nothing of our sequence and what we knew up until this point and would lecture about how we will be terrible programmers because we did not do something the way he wanted—though he failed to give us expectations or spend the five minutes to teach us basic things (run-time complexity, binary, pseudocode etc). His assignments were not related to the material and if they were, they were a couple of weeks off. Also, he never knew which class we were and would ask if we were 230 or 330 at the end of a lecture...
I learned relatively nothing from him (though I ended up with a B+) but thankful to be taking advanced data structures from someone who knows their stuff. He was awful. It was strange. Also, why did the uni not tell him what he needed to be teaching?

So I found this consulting job a while ago thinking that some extra cash while studying would be nice to have.
I meet with the guy, a researcher trying to start a business up, good for him I think, maybe we'll hit it off, continue working, why not? Except he has no clue how to write working code, all he ever did was writing matlab scripts he says, thats why he hired me he says.
Okay, fine, you do your job I do mine.
He hands me the contract, its about comparing two libraries, finding out which one is better suited for his job, cool, plots and graphs everywhere.
Except this is an unpaid job. YOU WHAT?! It's a test job. FINE. At least it'll look good on my resume.
We talk about the paid part where I'm supposed to scale the two libraries, looks good, as expected from an ML engineering perspective. It comes to payment. The dude has no idea how taxes work, says he has a set amount to pay and not a penny more. I explain with examples how taxes are paid, how you get reimbursed for them and so on. Won't budge. Screws me over.
Opens the door for other jobs I think, he'll learn next time I think and take the job.
Fast forward a month, 90% of the job done, he adds a third thing to compare. Gives a github link to a repo with 2 authors, last commit a year ago. There are links to a 404, claiming compiled jars. Fuck.
Not my first rodeo, git clone that shit, make compile, the works. The thing uses libs that ain't in no repo, that would be too easy. Run, error, find lib, remake all the things, rinse repeat.
The scripts they got have hardcoded paths and filenames for 2 year old binaries, remake that shit.
It works, at least I get a prompt now. Try the example files they got, no luck, some missing unlinked binary somewhere, but not a name mentioned. Cross reference the shit outta the libs mentioned on readme, find the missing shit, down it.
Available versions are too new, THE MOLDING NUTCRACKER uses some bug in an old version of the lib.
I give up. Fuck this. This ain't worth the money OR time. Wanker... -
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 😏7 -
//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.1 -
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...
The dreaded CAPITAL strikes, and requests of you to bend and fall onto your knees so as to provide intense, intimate and manual -- as well as oral -- PLEASURE to the [NOT SO] METAPHORICAL PENIS of the """SYSTEM""".
Oh, what an abominable, drooooooling revenant that lies before you!
"Gimme your ass... " he says, menacingly, as you wail about in a futile attempt to guard and preserve the very last vestiges of your own anal virginity.
And so you fight, and kick him in the NADS with everything you have, down to the final shreds of vigor. Victory! Or so you thought...
"You must... " he mutters, mortally wounded "update WhatsApp... "
"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?
We all know that ALL you need to help keep that honor intact is slaying your enemies in high-stakes combat. But how to satisfy less gallant needs, when male prostitution is outlawed in more than sixteen duchies?

This story just left me speechless in any way and i want to share it. tl;dr at the end.
Im studying computer science in germany and in the first of the small classes i noticed... no, i was disturbed by a guy who would just say that the thing we're learning atm were so easy and the teacher shouldn't even bother to explain it to the class. I don't understand why you would spoile a class that hard... I'm here to learn and listen to the teacher, not to you little asshole. (We were doing basic stuff like binary system etc. but still, let us learn)
So he became unpopular pretty fast.
Fast forward, a few weeks of studying later there was a coding competition where you had to solve different algorithmic problems in a team as fast as possible.
I came there, without a team because my friends aren't interested but I enjoy such tournaments. This guy and me were the only ones without a team and we had to work together.
After him being a total dick for hours i had to watch him code a simple for-loop, that iterates through a sorted array. Nothing special, at this point anyone could do that task in our class so it shouldn't be a problem for him.
He made a simple for-loop and it worked fine, but we figured we had to iterate through the array the other way around.
'Alright', I think. 'Just let the index decr..' 'Pssshhh', he interrupted me and said he knows exactly how to do this.
I was quite impressed when he started to type in 'public int backsort..' in a new line. He tried to resort the array backwards with a quicksort that he then struggled to implement. (Of course we had to implement a quick runtime and we needed that quicksort badly)
I was kind of annoyed but impressed at the same time. I mumbled 'Java has an internal sorting algorithm already' just to amuse myself.
He then used that implementation.
After a few minutes of my pleasure and multiple tests without hitting the requested runtime, i tried to explain to him why we wouldn't need to sort that array backwards and he just couldn't believe it.
I hope that he stays more humble after that..
Also we became last place but thats ok :)
tl;dr: Guy spoiles whole class, brags with his untouchable knowledge (when we do things like binary system). In a competition has to iterate through a sorted array backwards - tries to implement a sorting algorithm to sort it backwards first. I tell him, we could use a already implemented java method. Then tell him we could simply iterate through decreasing the index. Mind-Blown2 -
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... -
!rant
So I decided to collab with a website's maker (who i wont name here) to create something like r/place. (not an exact copy.)
I decided to start by learning their API, and customizing the server later.
I asked the guy for some help, and HOLY SHIT.
Let's start off by this: I had to request a chunk. The response data was in binary. 4 bits meant 1 pixel, so right away, I had to deal with that in my code.
No problem, just decided to use C# instead of JS. (see https://www.devrant.io/rants/547013)
I was finally done after a couple of mental breakdowns, and decided to implement updates.
I needed to use webhooks, and that was completely fine. But when I got "C1FFFF0000CA06" as response (in hex), I seeked some help.
C1 is the operation type: it means that a pixel was updated.
FFFF and 0000 were the chunk coordinates. But remeber: it's a signed integer. Guess what, I had to use Two's compliment. I decided to be a lazy asshole and only check for "00000000" because I was only displaying chunk 0,0.
CA06: This is a weird one. It's 2 bytes, and CA0 contains the X and Y coordinate of the pixel (in the chunk), and 6 contains the new color of the pixel.
I was sent the following code to work with 0xCA06:
color = 0xF & buffer
x = buffer >> 10
y = (buffer >> 4) & 0x3F
So I tried to do it, and it didn't work. I'm not blaming the developer of the server (original dev is reddit) because maybe I screwed up, but which guy will have a night of frustration and debugging?
Me.
P.S.: Dev, if you see this, I'm sorry. This API is way too complicated. I know we need to save bandwith and stuff, but damn.1
