Search - "great algorithm"
Some sort by Date, some by length, others by upvotes. But devrant's algorithm is so great it sorts by sarcasm.4
So at school the teacher gave us a MONTH to write a sorting algorithm in Java. I asked the teacher if that wasn't a little too much time.
Her answer:" I want to give the weaker people in class a chance."
Okay so far so good.
The day we had to turn in our code I asked around what algorithm others had choosen and if they had any problems with it.
Classmate A: "yeah we didn't know how to program it so we copied it from the internet and I modified it heavily."
Me *raised eyebrows*: "can you show me?"
Me: "but that's exactly the same like the first Google result?!"
A:"No look there , I added this line so that it works with my code"
That lying bitch just added bucketSort(myArr, maxVal);
In the main method.
Me"How is that heavily modifying?"
A:"Also I asked the teacher and she said it was OK to copy the method from the internet"
What the flying cunt is wrong with people. So you give us a month to copy and paste from the internet.
Yeah great teaching.
You are the reason why half the class can't program shit.
Thanks for nothing. 😒😒
First rant hope you enjoyed it.12
I wonder, do you also sometimes take a tech book and read it like a novel?
Maybe I'm strange. It's just thrilling to read about a new problem and wonder 'oh my God, how will they solve it' - can't wait to read on 😅7
A dev team has been spending the past couple of weeks working on a 'generic rule engine' to validate a marketing process. The “Buy 5, get 10% off” kind of promotions.
The UI has all the great bits, drop-downs, various data lookups, etc etc..
What the dev is storing the database is the actual string representation FieldA=“Buy 5, get 10% off” that is “built” from the UI.
Might be OK, but now they want to apply that string to an actual order. Extract ‘5’, the word ‘Buy’ to apply to the purchase quantity rule, ‘10%’ and the word ‘off’ to subtract from the total.
Dev asked me:
Dev: “How can I use reflection to parse the string and determine what are integers, decimals, and percents?”
Me: “That sounds complicated. Why would you do that?”
Dev: “It’s only a string. Parsing it was easy. First we need to know how to extract numbers and be able to compare them.”
Me: “I’ve seen the data structures, wouldn’t it be easier to serialize the objects to JSON and store the string in the database? When you deserialize, you won’t have to parse or do any kind of reflection. You should try to keep the rule behavior as simple as possible. Developing your own tokenizer that relies on reflection and hoping the UI doesn’t change isn’t going to be reliable.”
Dev: “Tokens!...yea…tokens…that’s what we want. I’ll come up with a tokenizing algorithm that can utilize recursion and reflection to extract all the comparable data structures.”
Me: “Wow…uh…no, don’t do that. The UI already has to map the data, just make it easy on yourself and serialize that object. It’s like one line of code to serialize and deserialize.”
Dev: “I don’t know…sounds like magic. Using tokens seems like the more straightforward O-O approach. Thanks anyway.”
I probably getting too old to keep up with these kids, I have no idea what the frack he was talking about. Not sure if they are too smart or I’m too stupid/lazy. Either way, I keeping my name as far away from that project as possible.4
How it feels to be an intern : "Omg I helped people making an app in reactJS I feel like I improved a lot in the past months"
How it feels to come back at school : "omg I have trouble writing a simple algorithm I feel so dumb I'm the worst dev in the world"
That's the difference of working in a team with a great mood and close to no-stress AND studying while having to deal with social anxiety.
The conditions in which I work have a huge impact on the way I feel about myself, my skills and basically on my motivation.3
Guys some great tutorial about "neural net" and "genetic algorithm" ?
I would like to learn how it works but cannot find good tutorial1
Computer engineering : Insanity!!!
Today a friend of mine was assigned to make a Client-Server Encryption using Sockets. The guy did a great job applying BlowFish algorithm, but the teacher was disappointed because she couldnt map letters to the encrypted text and she declared the program to be wrong!!!2
If this isn't the worst thing.
I was asked to develop a WordPress plugin as an intern developer and I've been on it since last week. I got stuck when i finally had the loops running but couldn't find a way to format the output without overwriting the existing values on each iteration.
For the last one week I've been showing the progress on my code to the CTO and this is how it has been.
Me: Hello. Everything is coming along fine, I have most of the functions running properly, do you mind looking into the algorithm?
CTO: Oh not at all, let's see what you got. Omg great code for an intern. I think you should add a new variable there and maybe clean up that function over there because it's deprecated now and yeah HaHa, Great work.
Me: Thanks xD I'll have it finished latest next week.
CTO: Oh great. I can't wait to see what you'd have by next week so we can install it on our WordPress.
*Next finally week comes and I'm done with the code.
Me: Hello, I'm done with the entire code! Want to take a look? The plugin works just exactly as described.
*CTO takes a look
CTO: This is completely bad programming practice, so you are running 4 nested loops that all send queries to our data base and make changes to data. This would have a very drastic effect on the server considering the traffic we get.
Me: But you saw this exact code last week and said it was okay, I only changed some CSS since the last time.
CTO: Omg, we can't accept this, you have to develop it again from the scratch without using those loops and queries.
Me: What? Okay, fine. Any hints?
CTO: Just start. That's the greatest hint I could ever give. And also, always have a plan before you begin.
Me: Yeah, thanks for those. It's the first time I'm hearing them and they would totally be applicable to building this thing.2
i honestly hate the ap computer science principles curriculum. we're taking an ap test soon, so for the past few weeks, we've been constantly taking practice tests.
it pisses me off so much. the questions, the criteria, it's all bs.
we have questions like "what will reduce the digital divide?" with choices like "education for low income families on computers." like, I DONT FUCKING KNOW.
frankly, I DONT FUCKING CARE. giving electronics to people who cant afford it is great and all, BUT IT DOESNT INVOLVE ANYTHING ABOUT COMPUTING.
HEY, COLLEGE BOARD, KNOWING IF AN ALGORITHM IS TECHNICALLY AN "ABSTRACTION" DOESNT FUCKING MATTER. WHAT MATTERS IS THAT I CAN IDENTIFY WHATS MORE EFFICIENT, WHERE A BUG IS, CONCEPTS INVOLVED IN PROGRAMS, THINGS LIKE THAT.
NOT IF DNS IS SIMILAR IN STRUCTURE TO THE US POSTAL SYSTEM.
god i hope whoever wrote this gets hit in the head by a github server that was dropped from the 2^8th floor.2
while reading rebecca & brain's book on object oriented software. I realised that the programmer is a special kind of person. the complexity he can handle, the struggle to implement a system, from input to output, satellite control, AI, robotics, heck, even the planning required for a simple android app, the complexity is overwhelming at first, then you get your jotter and break it down into parts, and you drive yourself to the edge of sanity figuring out an algorithm, then you go over that edge implementing it, but oh that great super hero feeling when you finally get something to work exactly as specified, I'm not sure people in other professions can understand the satisfaction. I'm very young in the whole programmer world, but I'm growing fast, I'm just really grateful programming found me, I mean, can you think of something else you'lld rather do? yeah, me neither.4
Friends were having great and fun time last night partying after (also) last week partying.
And now someone's having friends over for dinner in the shared kitchen.
While here I am hours staring at my screen trying to break the algorithm.
Me : Enough with coding! I need social life!

*Checking devrant and reddit/programminghumor2
8 years ago,
I studied in a small school and every year we had computer classes, but most of the times, it gets cancelled or we just sit and browse and sometimes few of us don't even get a computer.
In that time, the only reason I was attached with the computer was due to games.
Our curriculum mentioned HTML, CSS, Access and Excel, which none of the teachers taught us for past 2 years. I wanted to learn all does, but gave up since no one cared about it.(please note that time, I didn't know even to use YouTube or W3schools to learn stuffs)
Then, a new student joined in our class and also a new computer ma'am joined our school. Both of them turned out to be really fun when it comes to learning computers.
She was active during last sessions and teach us HTML, CSS. I even started writing blogs which she taught. The most surprising part was she was super frank. She went beyond her duty, and taught me what Facebook is, how to use it, and opened an account for me which I am still using it, and she sent a friend request to herself. (In lab, past teachers would shout to students trying to open fb. All of them were super strict.)
She was kind and friendly, and during theory classes, the new student in our class would answer every single question. Then, somehow we both started sharing sits in computer class, and he will tell me answers and we both raise hands to answer the question. My teacher will also keep asking interesting questions which made me more inclined to computer science.
My story isn't related to learning a programming language or an algorithm, but it was the wave that brought me closer towards CS and after 2 years, I joined CS in University and till now, haven't look back and always thanked both of them, my respected ma'am and my dear friend, who inspired me and brought out my curiosity towards computers.
Note: My friend is doing Medical currently and when I teased him that I did CS and now, I know more than you and this time, I am gonna whisper in your ears if someone asks any question, to which he replied, I accept I am doing Medical, but I still love computers and know a hell lot about it.
My teacher got married and she also got a cute baby. We talk occasionally in fb and she is going great too.
I hope to meet both of them someday soon.
The post-filter algorithm on devrant is really great I'll have to admit it!

Could this be image meta-data comparison? How does it...?2
It's been a while since i stopped programming.....
It's been so busy with all the school work/assignments/ and the most important part is that school ends at 10pm, arrive home at 11pm, prepare for tomorrow school stuff, sleep at 2am, wake up at 7am next morning, and again ends at 10pm 5 days a week...
It is exhausting, but I am getting used to this routine.
Studying my own programming skills or working on a side project? Not sure when to do it... The only way to continue studying is at breaks at school, or sleep less and study....
But it is impossible....
I have some great projects that are waiting to go out to the world, to list a few:
- cloud gaming
- cloud storage with live streaming
- complete school schedule management
- home automation framework in dotnet
- deepfakes and ai image generation algorithm (~18 months of training till now)
- game cheat engine (20GB total omfg ^^)
- and more
and I don't have time to finish it. lol
I think it will see the bright world after 3 years of high school... By then, my projects will be ancient, probably....
TIme is really short.
24 hours equally, but feels like 8 hours a day....
Should I abandon the project rn and focus on studying? (probably should)
or should i sell the project or open source it?
Also, how do you manage your time between work(study) and side projects (especially big ones)?5
I have an internship at some research company. My point is making face recognition apps with prog lang I know. This place is awesome. Well, compsci it's not my background, but I met many people. And they are great at math ....
... Like they do 29 gray-scale images as a vector for PCA algorithm with size 64x64 pixel and COUNT A COVARIANCE MATRIXES WITHOUT TOUCHING ANY CALCULATOR OR PEN AND PAPER AND GET THE RIGHT NUMBER!
Man, this is insane. I don't even know 64x64. I love compsci1
I finally published my first open source project. A package for calculation a geohash of a geolocation for pharo smalltalk.
I know that most of the users don't know smalltalk but it's the best OOP you can code with. And geohash is such a great algorithm. Lovely combination2
(imagine all of this said in Undoomed's "hey moron" tone)
Hey, moron, fuckin moron! How about if you're a noob with no actual programmer on your side, you just tell me so we can work it out together, instead of sending a moronic 4page "acceptance criteria" that pretend you know what you're talking about, and then bury me under loads of moronic noob questions that reveal you as thenmoron you are, all of that for a fuckin 50 quid?! I thought it's me being an idiot, not being able to do the task within two days timeframe, but now I see you're just too much of a moron to have any idea how much these things take. And now you nonchalantly mention a one-line one point from the four page document full of drivel, which (loads of moronism credit for me here) i didn't notice amongst all of that other mundane drivel, which actually like doubles the whole workload on the task, but your moronic document, which makes 3 parts of the same algorithm into three separate MILESTONES, makes this whole thing that nearly DOUBLES the workload into a shitty SEVENTH SUBPOINT of the completely unrelated first "milestone"?
FUCK YOU, YOU STUPID ROBBERY CHEAPFUCK, and fuck me for letting myself be tricked by all your fancy wordings that pretend you actually know what the fuck you are asking for, so i assumed you did, so I missed THE POINT, WHICH ACCORDING TO THE SEGMENTATION LOGIC OF THE WHOLE REST OF THE DOCUMENT SHOULD BE 3 SEPARATE FULL-SIZED MILESTONES, NOT A SINGLE SUBPOINT, YOU FUCKING FUCK!
... so much for still trying to at least a bit trust people.
FUCKING DISGUSTING MORONIC CHEAPSKATE FUCK.
and I can't even tell him to fuck off through the rectum he came here because he's all nice and polite so I would be the asshole!
"hey, please, can you build me a house?"
*house is basically finished*
"oh, great job, i love it, but i think you might have missed the fineprint in our contract that says that the house is supposed to stand inside an entry hall of a multibillionaire-sized mansion, so could we please sort that out and add it to the building real quick before i pay you the toolshed's worth we agreed on based on the contract? "
i thought i can be a shitty liar and a con man, but this is some next level shit that would be totally beyond my abilities to pull off...
YES I KNOW IT'S MY FAULT I DIDN'T COMB THROUGH THAT BULLSIT "SPECS" OF HIS LETTER BY LETTER TO MAKE SURE THERE'S NO CON BULLSHIT LIKE THIS HIDDEN AMONGST ALL OF THAT MUNDANE SELF-EVIDENT PSEUDO-TECHNICAL DRIVEL, SHUT THE FUCK UP.
fucking disgusting moron, pretending all nice and innocent probably even to himself because he HAS NO FUCKING IDEA WHAT HE EVEN ASKS FOR.
i bet it's one of those pukefucks who get an overpriced contract for 50k without even knowing or caring what programming is, because "i'll just outsource the core functionality of the app for 50 quid to some naiive idiot who lives in the illusion that people are not diarrhorea-worthy pieces of feces, and this other third of the app to some other moron for hundred quid and then i somehow outsource gluing it together to some third poor sod, and that's 49.8k quid of pure profit for me, yay"
and now i'm torn between three options, just cancelling the "contract" with a comment saying "fuck off, you con man", or cancelling it with a lengthy explanation why he's a know-nothing piece of shit who conned me already into having done something worth about 5x more than his shitty "acceptance criteria" requests, or just start conning and bulshitting him back, which won't net me any money, and waste my time, but at least will also waste HIS time, which might be nice because he seems to be on a tight schedule so if i play this right i might have the chance to sink his whole contract which might be mighty nice satisfying...
FUCK THIS, ALL OF THIS, FUCK HIM, FUCK ME, FUCK ALL OF YOU, I SHOULD HAVE STARTED FUCKING OVER EVERYONE RUTHLESSLY A LONG TIME AGO BECAUSE FUCK THE WHOLE WORLD, WHY SHOULD I CARE WHEN NOBODY ELSE DOES, WHY SHOULD I BE DECENT WHEN NOBODY ELSE IS, AND IT ONLY ROYALLY BITES ME IN THE ASS.
stupid fucking lobotomized fuck, IF YOU DON'T KNOW HOW TO DO SOMETHING, DON'T OFFER YOURSELF TO DO IT FOR MONEY AND THEN CON-SOURCE IT TO OTHERS YOU SHITTY BARFPILE!
Tfw your algorithm ain't even that great compared to the others, but you still hit a 18/20 cause you did the project in the teacher's language and alone :maximum_dabbing:
I was thinking to read some books on algorithm and mathematics required in programming, especially for CP. After some searching I got across some books that are considered great in the field. Among the books, 'Introduction to Programming by CLRS', 'Algorithms Design Manual by Steven Skiena', 'Concrete Mathematics by Donald E. Knuth' and 'The Art of Programming by Donald E. Knuth', in which order should I read them? I've already started reading CLRS as it would be required in my college course too.5
Recently created an app and uploaded it on Play Store. The download rate was great until a few days back. Suddenly I saw that the download rate was dipping drastically.
Then I read, "Download rates of new apps on playstore dips because of change in play store algorithm".
Wow! Thank you Google! Also, fuck you 😐
So I have a huge family, and a core group of close friends, but I'm the only semi-tech-literate individual I know. The closest I have is a relative that uses a drag and drop interface to control some "internet of things" style systems in his 9 to 5. DevRant is great, and reddit can be, any place/platform/bar/dogpark you all use to meet other devs/engineers/algorithm junkies? For context, I'm a remote dev for a small team, purty much solo...
So on my new position I get to work on Spark jobs. Never had to work with the infamous big data technologies. I never thought this would get SO frustrating for all the wrong reasons.
I'm currently trying to introduce integration tests for some Spark job I wrote. This isn't trivial though, as the data comes from several HBase tables. Mocking everything simply isn't feasible. So why not use the integrated HBaseTestingUtility? With it you can start a mini cluster that runs all nessecary services in the scope of your test.
Sounds great, eh? WRONG. Firstly the used mapr dependencies get in the way. The baked in configuration tries to automatically authenticate with your local cluster through Kerberos. Of course this doesn't work. And of course there is no way to reconfigure this as it happens IN A FUCKING STATIC BLOCK. AHHHH.
Ok. So after calming down I "simply" had to exclude all mapr dependencies and replace them with vanilla ones. After two days of dependency hell it FINALLY works!
...or does it? Well now we need test data. For that we got a map reduce algorithm that can import dumps. Sounds again, great, eh? WROOOONNNG.
The fucking map reduce mini cluster can't start, as it tries to write a symlink. Now take a wild guess what the sys admin here blocked. Yepp. TWO DAYS OF WORK RENDERED USELESS, BECAUSE OF SOME FUCKING SECURITY SETTING.
This is fine.
