That moment when you make your code such that even dummies can understand it, implement smart ass algos, do all those comment line things for definitions. Then you show your project to your teacher who has this to say :
"Why are you showing me copied code?"
I am like

Algorithm: from the Greek "algos" (pain) and rhythmos (repetition), we derive the true meaning of this word: REPEATED PAIN.

:D

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

The algos have aligned

When I'm coding, I often come up with some cool algos and when I do, I feel pretty good.
But the next second, I get this feeling that I know there are a million other people in the world who have solved the same problem with the same or better algorithm and I feel like shit. Like all the work I put in is somehow redundant.

Like finding answers on StackOverflow... When you do, you know the person who answered has already done it. You're just repeating it. But again, the fact that I'm looking for answers from other people in the first place is ....

I don't know. I guess I need to change the way I code from now on....

I went on an interview was given an algorithm to solve, solved it in 30 mins and they had allocated 20 mins for it. So I guess I suck. I build shit, I don't do algos that often so I'm obviously rusty.

interviewer: so why should we hire you over a CS graduate.

me: cause I can get shit done.

... akward silence

interviewer: what do you mean by that? like html and CSS?

me: as you can see, I have built large scale real-time web apps with React/Redux (the stack they supposedly use and the position they're hiring for!) the knowledge I have is practical, it can't be learned from books, and it can't be learned from a course. Only building, breaking and rebuilding over time will teach you this knowledge. So essentially a CS grad, who hasn't committed the same amount of hours as I have, can't possibly match me. But they probably can better explain the real world applications of using linked lists...and won't have to Google what Pascal's triangle is like I had to....

interviewer: I see. we will be in touch.

lol well I guess they'll be in touch..

Devrant algos on point.

My worst experience was at my job where they told me I have to move to a permanent position from 3 years of contracting without a specific offer.
Why is that bad? In my country it means approximatly 40% lower wage.
I came into the job with PHP knowledge when they were looking for Perl on a project one year behind schedule. I learned the language and finished working demo in 6 weeks.
After that, every project that was ever assigned to me was done within 5-15% of the allocated time. I'm not kidding here. My manager loved be, because I was reliable, fast and I even 'accidentaly' solved other problems, like for instance I developed simple syslog search tool and benchmarked zip algos for reading speed, and the fastest had 70% better compression than the algo used before (gzip into plzip on 1-2gb files). That solved anothet problem - syslog servers did not have enough disk space and they didn't have money to upgrade the server.
The number of projects I touched or developed was over 20.
I also lead and developed our team's most successful tool, that every customer was throwing money to buy, while cutting down costs everywhere.
And after three years of that, my manager says that there are no more money for contractors. And the only possibility is going for employment. Without any specific offer! Just 'we cant do this anymore'.
Which I understand, that can happen in corporation, but ffs after all I've done, I expected warmer attitude. Not like 'you may have to leave, since we do not really care'.
I liked the people there, even though the corporation environment was lacking in many respects, but I wanted to help our local branch with everything I could and they gave up on me like that.
So I started looking elsewhere and I found a startup which offered 6 times the money I had in my previous job and promises to relocate me to USA. Which is the best thing that has happened to me that year and second best in my whole life!

All motherfuckers who set their stupid website to try to send you notifications must burn in hell after they die. I am tired to setting every browser I install to always block notifications because of that stupid morons.

I see loads of students here.. and loads of freelancers and startup joiners.. all varieties...but one.. Anyone has a 'normal' 9-5 or sth (dev) work? Does that even exist?! Anyone stands up when the 8h are up and can leave the work behind?
I can't.. even when I leave the office I have algos & code stuck in my head..trying to solve the problem I worked on..

How do you handle non dev life? Is there anything left in a day?
I usually work monday-friday on avg 9h/day and have no idea how to manage not being fucked up at the end of the week. :\ I am trying to get back climbing, but usually I am just soooooo tiiiiireeeeeed after work.. I wanna sleep but when I close my eyes I see the code.. at least one core still left working..

If anyone has been keeping up with my data warehouse from hell stories, we're reaching the climax. Today I reached my breaking point and wrote a strongly worder email about the situation. I detailed 3 separate cases of violated referential integrity (this warehouse has no constraints) and a field pulling from THE WRONG FLIPPING TABLE. Each instance was detailed with the lying ER diagram, highlighted the violating key pairs, the dangers they posed, and how to fix it. Note that this is a financial document; a financial document with nondeterministic behavior because the previous contractors' laziness. I feel like the flipping harbinger of doom with a cardboard sign saying "the end is near" and keep having to self-validate that if I was to change anything about this code, **financial numbers would change**, names would swap, description codes would change, and because they're edge cases in a giant dataset, they'll be hard to find. My email included SQL queries returning values where integrity is violated 15+ times. There's legacy data just shoved in ignoring all constraints. There are misspellings where a new one was made instead of updating, leaving the pk the same.

Now I'd just put sorting and other algos, but the data is processed by a crystal report. It has no debugger. No analysis tools. 11 subreports. The thing takes an hour to run and 77k queries to the oracle backend. It's one of the most disgusting infrastructures I've ever seen. There's no other solution to this but to either move to a general programming language or get the contractor to fix the data warehouse. I feel like I've gotten nowhere trying to debug this for 2 months. Now that I've reached what's probably the root issue, the office beaucracy is resisting the idea of throwing out the fire hazard and keeping the good parts. The upper management wants to just install sprinklers, and I'm losing it.

First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.

Second year:
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.

Year three:
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.

Honestly? I was always good at maths and creativity. And so, programming was natural to me. I was always good at it with minimum effort. ¯\_(ツ)_/¯

... Algorithms were a whole other story tho. I'm still not confident 'bout any algos I program from scratch. But hey, if it works, it works. (that became my motto about algos, kinda)

Forgot one thing tho: looking at relevant code to whatever I'm doing, be it in a tutorial or stackoverflow. I don't need the text or tutorial or explanation, I need to see code examples.

1. Building stuff is awesome!
2. It's creative work that actually makes cash
3. I like writing algos and math

Does anyone else here hate people who use numpy panda and tensorflow and call themselves data scientists ??
Cuz I hate 'em. There are so many researchers who work day and night to figure out the math and algos which go into these libraries. These researchers are real data scientists.
If computerss sciemce would have been a religion, then just using these stupid libraries and claiming you are a data scientist would be blasphemy.

Lets learn bubble sort!
Type the following code to Visual C++ 1998 and compile it. Then run it. Write the output to the paper i just gave it to you.

Reality:
• Takes 5 mins to compile and run
• Too many errors in the given code so obscure output
• Teacher thinks we are so smart that we can understand c by typing and looking at the output.

The worst part:
• Different output per compiler
- Correctly compiles in the compiler in VC++ 98.
- Differs in GNU GCC, compiles wrong
- sends out obscure dummy output in VS2015~2017
- Works well in tutorialspoint.com compiler

WTF is this, guys?

@@@@@@@@@@@@@

Oh, and i have gone off topic...
Why does he think we are smart that we can understand bubble sort, and 4 more by only typing the code and looking at the output without knowing how does this algo work?

@@@@@@@@@@@@@

Answer to weekly question.
The teacher said to understand sorting algos by typing the code and looking at the output which differs per compiler.

I've written two different real time audio resampling algos (called on source and called on target) using linear interpolation, both in typescript, both work on first try and both perform great. I feel like the omniscient god of web audio processing.

We use Unity in university to display the workings of algorithms.
Cus you know.. a little cross-platform 2d webgl is not enough.. we need this whole friggin engine with an IDE and its 1000 buttons and switches and need for an account and C#...

React router is shit
I have never seen more retarded library.

Not only those suckers change the 100% of the API every fucking update for no reason, also they have the most fucked up documentation ever.

No search in the docs!!! Fucking bullshit examples with no such easy things like how to create nested routes.

Please, stop using this piece of shit, I'm tired of working with this fucking abomination. Hope they will delete their shit repo one day.

Today at work, I finally had to use and implemented an algorithm they teach in textbooks... And also thought about Big O. I feel so happy as this is a first... All those hours of reading about algos has finally had some use!

Macbook keyboard is shit
Especially european variant.

I want to see any person in the world that is braindead enough to think that making short left shift if favour of having abolutely useless button there is good.
This is the most stupid decision that could be ever made.

Not only the symbols used by that button are seldom used, they also are duplicated on they other keyboard keys. But shift is used all the time and must be big enough instead of that shit.

Firefox is shit

- In version 62 the cocksuckers finally removed the ability to add description to bookmarks, now there is no difference between mozilla shit browser and chrome, except chrome has working mobile version and working bookmark sync.
- Yes, firefox mobile on android does not even allow you to edit bookmarks so that useless crap can't be called a browser at all.
- Firefox shitcoded sync takes more time to sync 1 bookmark, than chrome takes to setup all bookmarks/addons/settings on fresh-install and in addition to that, it messed my bookmarks several times, so I am forced to sync places.sqlite via dropbox to syncronize bookmarks, because it is way much faster and reliable.

Existing algos are messed up. The one that personalizes ur feed. FUCKKK.

My YT, Tiktok, IG, Reddit feed are mostly about suicide stories… I just interacted with some posts about anxiety and it led to this. Idk if it’s just me or is this really a trending thing? Coz it’s suicide awareness month??? But dude? That “awareness” might trigger someone contemplating it, like it taps into their confirmation bias.

I will never ever see, play, or think about video games the same way again. Even playing all my childhood games is never the same.

I will now forever see the game from the inside out, imagining what code the devs might have written to achieve what is happening: sprites, audio, triggers, AI algos, etc. No longer is a player or character just a player or character; they're sprites, animations, classes and variables and method calls. o.o

Headphones, phone in silent mode, my algos and data structures drawn on a sheet of paper, and a rubber duck by my side.

Searching for a user who reposted drones using coding and algos.
I just saw your github, looked to see, then phone died... Please reply.

WooCommerce is shit

Just try to find anything in the documentation on their retarded website and you will get what I am talking about.

A billion of unstructured links. With absolutely no sidebar or table of contents.
IMPOSSIBLE to find any fuck there.
It is far easier to build an e-store from scratch, than to customize their ugly monster.

Now look Laravel or PHPunit documentation to compare how it should be.

I got an interview for a software internship in SF! So happy right now! Extremely nervous about the interview, guess I have to study up on some algos :)

All mail clients are intentionally made not to show sender email address, but rather their chosen name to then launder money on anti-phishing trainings.

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?

!rant

I've always been wondering why do tech companies need everyone to have a strong grasp of algos and data structures?

I've been coding most of my life but didn't get a CS degree so ended up in IT but I kind of want to get into a tech company as my thinking is the quality of code much higher (I spend a lot of time cleaning up other people's code and prod issues over the years...), I've been learning Algo/DS but when I see those technical questions on CareerCup, I go WTF.... it's this the kind of problems you guys do every day?

CORS is shit
Stupid useless shit that protects from nothing. It is harmful mechanism that does nothing but randomly blocks browser from accessing resources - nothing more.

Main idea of CORS is that if server does not send proper header to OPTIONS request, browser will block other requests to that server.

What does stupid cocksuckers that invented CORS, think their retarded shit can protect from?
- If server is malicious, it will send any header required to let you access it.
- If client has malicious intents - he will never use your shit browser to make requests, he will use curl or any ther tool available. Also if server security bases on something as unreliable as http headers it sends to the client - its a shit server, and CORS will not save it.

Can anyone give REAL examples when CORS can really protect from anything?

I feel like a total dickhead, might fuck around and implement some data structures and algos in c++ later idk.

Dev rant needs to work more on their algos to show rants! Since I posted one bout php , every other rant I see is bout php now and I think I just shot in my feet with this rant 😂oh whatever.

Any simple, easy algos for solving the last/top layer of Rubik’s cube, anyone? This is the part where I always get stuck and have to google.

Now it's over and failure seems certain...

In fact I'm certain that the interview app on my browser flickered for a second and showed some form with a red Failed text before displaying a Thank You page...

So it seems if I really want to get a tech offer, I have to focus on algos big time.... Hm....

I'm curious, how many of you ranters out there studied Math at an advanced level to become proficient at programming? Is there a particular field of Mathematics that would improve my programming skill?

Context: I come across a lot of Math I don't understand/never encountered when researching topics such as encryption, hashing, geospatial data handling and randomness. Was wondering if I missed out on some key learning that would make these topics a lot less mysterious. Also, I overheard someone coming up with a mathematical formula to base an algorithm on. I don't think I've ever come up with algos this way.

I think that the idea of IIFE in JavaScript is a good example of how shitcoding can be built into the core of the language.
How can I make my code clean if the language itself forces me to make such an ugly constructions?
What do you guys think about it?

People responsible for closing threads on stackoverflow for "We don’t allow questions seeking recommendations for software libraries" should die and rot in hell forever.

Twitter comments are shit
How the fuck to use them? Why don't they just show one under another? If post has more than 2 replies it can be clicked to open its direct replies, some of them are shown in main thread, some of them are shown under opened thread. Some replies from main thread are shown under child thread. And to make it even worse any comment of sub thread can be expanded as well showing some random replies that could be expanded recursievly so you may end in main thread again. It is just impossible to read all replies in chonological order. Show me the moron who made this, I wanna kill him....

my biggest lol moment was talking to some hardcore always bring in your own algos and ds games to the table, always going to the core of the world devs, better than thou my shit is better than you ass, my point of view is the best in the world devs, cite papers and algos to you devs, shit like that that were making way less money than some dudester ruby on rails dev sitting at the the conf sipping on his drink.

Really, all that comp sci shit is legit and fun as fuck. But if you are not getting the green for it and living the life then what is the fucking point. Even then, those that are are normally fucking morons. This shit ain't some art, or a personality trait, it is a job.

Fuck me i am so tired of the whole hacker news reddit ass SO mentality of devs, then again I am also tired of mfkers with no knowledge of actual engineering publishing medium articles left and right.

As long as you cannot take human error out of this computer equation you will always have a shitfest of opinions, because regardless of correctness you will always have a shitfest as long as some dickwad has a difference of opinion in an otherwise young ass scientific field such as computer science.

Language wars, framework wars, editor wars you name it. This field is so fucking broken and so full of shit it ain't funny, made less comedic by the fact that it runs the world.

If we are going to die it will be by some massive kernel panic made possible because somewhere, some morons could not mergr a repo due to conflict in ideas. As if being right was going to bring you closer to not being an ugly fat nerd and getting pussy, or dick, whatever your flavor is you fucking losers.

I’m always tired all the time. Depression and what not but today I am TIRED

Had an interview that requires vanilla javascript but I suck at algos even tho I was getting it done till time ran out. We gelled tho so I hope they see potential and move to next round.

But the good news is. I had a follow up interview based on a challenge. It’s the second I’ve ever had and I did well this time.
So much so that they’re booking another interview for tomorrow.
So I’m done with the technical portions of the process.
This is the first time I’ve gotten this far and I’m so happy. I’m hoping really that this is the one cause I doubt I have the energy and will power to keep going though the processes.

I’m so excited. It’s as if all my work is slowly showing and I’m getting closer and closer

Wish me luck guys. Hopefully I ace it as I come across well In General Chats.

This is my last application. If it doesn’t work I think I’m done with dev life and job hunt.

Fingers crossed I’ve found the one

So today at work, a dev proposed some solution to a performance problem by using divide and conquer. But the way he said it was came across like "this is a brilliant, algorithmic solution, I bet you'd never think of this because no one else knows algos".

So then I just reply to him mentioning Big O and how it seems the performance is N^3, exponential. In which case the optimal size is like 1. But basically like starting an algo discussion to see if he can keep up... Or if he's just dropping some algo slang to look good.

New gmail is shit, better make a gcloud app for linux instead of redesigning that shit billion times, you fucks

Today is a sad day.

I loved Songza from day one. Google bought them, but kept their functionality alive via google music.

Today goole transferred google music to youtube music.

My beloved algos and functionalities of original Songsa are GONE. And their new shitty service propose only playlist. 0 AI, 0 machine learning.

Anyone knows a free music plateform I can migrate to ?

1. Teach DS and Algos. Not basics but advanced data structures and the ones that are recently published.
2. DBMS should show core underlying concepts of how queries are executed. Also, what data structures are used in new tech.
3. Teach linkers, compliers and things like JIT. Parsers and how languages have implemented X features.
4. Focus on concept instead of languages. My school has a grad course for R and Java. (I can get that thing from YouTube !!)
5. Focus a little on software engineering design pattern.
6. It's a crime to let a developer graduate if he doesn't know GIT or any version control. Plus, give extra credits for students contributing to open source. Tell them if they submit a PR you get good grades. If that PR gets merged bonus (straight A may be ?)
7. Teach some design pattern and how industry write code. I am taking up a talk at school to explain SOLID design pattern.

Mostly make them build software!
Make them write code!
Make them automate their homeworks!

Make them an educated and employable student.!

Does this book worth reading?

Hello I've finished several books about JavaScript already and many of them mention this one

JavaScript: The Definitive Guide, 6th Edition [2011]

I am a bit embarrassed, because despite it looks like a thorough 1000 pages guide, its last edition dates 2011 year.

From one point of view, it should contain core concepts that still remain the same, from the other, reading 2011 book in 2018 sounds like a not very good decision.

What would you say?

This story happened to everyone, and i am sure that if i search, i will find dozens of similar stories, but the different here is, i tried, i really tried, in a hundred different ways to achieve my goal !

When you are stuck on a problem, let's say, that you have a program, project, website ... and need to achieve something technically weird (or hard) and need some help to save you time on experimentations. The first thing a lot of people do is : Google.com && put search dorks.

But, at a moment, google gets "dirty", you use it so often that he always think to know better then you what you are looking for.

It reminds of "Ted", the movie (for thows who know it) where they asked : "Hey ! Why does google always suggest us to look for black dicks ??"

It is exactly what happened to me, i got results who doesn't have anything to do with what i was looking for !

You can give it a try now : type "semantic web RDF to RDB"

You won't find anything, except results related to : NOSQL DBs, which is totally annoying.

Something else, i once google swift to get some updates, what results did i got ? Taylor Swift ... (musician)

I often get 2 or 3 results from google, which made me thinking that i somewhat reached the end of internet, or that people are so dumb that i will have spend hours trying to figure my solutions, but, before doing that, other solutions had to be tested.

1- TOR : Google tracks his users and uses its algos and bullshits to return results as close as possible to the user's demand (big fail ...) so how about moving to a different country ? DL TOR browser, open, setup, go to US, open google (got us version YAY !) enter my keywords, and, nothing, still nothing, more results for sure, but nothing related to what i was looking for.

2- VM
Pop a VM, launch TOR, use Hidden mode, delet all cookies and stuff (it is a new VM but who knows).
Use keywords (now in UK). Here they are !! my results !!! i finally found some decent results about my keywords !

But, i have the required knowledge to do this kind of stuff, but how about people who rely heavily on google ? they can't change country, clear everything, trick google to think you are a new user, they have almost biased and flawed results. I tried duckduckgo (i love them) but they are not that efficient.

Google says not to anything evil, but they ARE EVIL, miss guiding people, suggesting corrections who have nothing to do with the keywords, or results totally unrelated in any way to the keywords while results exist in other countries ???

Ever since, i don't pay attention to google at all, and started thinking that google's algos are manipulating people, i don't know if it is done on purpose or not, but the result is the same, people have biased results based on their country, on their tag, on their ID, and the recent keywords.

During that period i was cursing google every funcking day, and i am still doing it, too much trackers, too much manipulation, i will end-up enclosing myself in darknet.

When you complain to a teacher about the lack of challenge in another class and he tells you he's gonna make you build a sudoku solver.

I'm getting quite bored from doing the mini c++ assignments and was talking about it to another teacher when he explained he'd got a background in AI and algos so he told me he'd teach me some more interesting stuff :D

Any resources for self-learning algos in Python?

Python maybe to high level so C# would be good to.

Clarification I am looking for resources AI learning itself and not me learning it.

I use to develop desktop programs in C++ with algos related with image processing and computer vision. However, new projects appear and one of them was for web using Drupal. It was my first experience with web and I am still having nightmares... It is the worst thing you can do. Continue a big project without the understanding of technology nor the framework... Now I am more experienced and I prefer stacks like MERN. Easy the debugging in web i so crucial... Maybe, I would have to swtich to webassembly.

What is the best string comparison algorithm ?

Example Use case: group messages from your telco into groups of related messages.

I have gone through the various algos and implanted them. I just want your opinion if you have experience on this.

Every single time I get in a lift, I think about how it schedules, however, I don't recall the algos well.

Anyone have experience with technical analysis, algo trading?

Was reading an article about how markets are probably going to crash next year based on some technical indicators and it reminded me of the days back in uni when I tried to create (simple) trading algos using all sorts of technical indicators...

Never got anything better than random... And I recall was basically throw some indicators together and backtest using different parameters. I think it's called p-hacking.

But anyway just wondering how is it actually done such that it works... And well how can technical analysis ever work if it's completely subjective to the parameters u use? Like just take Moving Average. You can take a average over any range 1s, 1min, 1d, 1 month, etc.

So many combinations u could use, how can you make any rules that you are confident enough to put lots of money on...

I feel compelled to figure out how to use software in a gaming setting to teach skills like CS and Math. But do it in a way that is fun and not feeling like a "math game".

I want to spend more time learning about algorithms, architectures, design approaches, etc. Writing such a game would force me to understand what I present in a very intimate way.

I can see a way to create algos in game using very visual ways. Then allowing someone to make superstructures combining those algos to solve tasks.

I was inspired by how some algos require data to be sorted a certain way before starting. As the algo as a side effect resorts the data to know when it has completed. I realized if an algo is generic enough it can be combined just like functions or objects.

I also want to learn math better, especially in conjunction with code. So making a platform for learning these would be a lot of fun. I would definitely want both visual and textual interfaces to the code. I have to imagine a real programmer being frustrated with a visual interface unless it was really compelling.

I find it interesting that a lot of algos are represented visually when trying to show how it works. I realize some probably cannot be visualized so easy though.

I also want to use software like this to teach someone to think more deliberately and help people be more disciplined in their thinking. I know I could use this.

I have a secret goal of being able to use such software to help someone become a math/programming wizard. I don't know if this is achievable, but having exercises that help solidify root concepts in a fun way would be really useful IMO.

A) Take a test consisting on Data Structures and Algorithms in C or C++ or heck even Java

B) Turn in as a final exam a screenshot of you completing Sekiro: Shadows Die Twice

I had an easier time passing Data Structures and algos when I was studying, even with a high grade vs the amount of ass whooping I got myself handed on that game the first playthrough (now it is easier, but still)

When learning a new language I look up public repos on github, specifically those who are just collections of algos in different languages, and take a look + try to implement it in a different way. The good ones also have maintainers that actually take a look at your code when you open a PR and give you some hints if they are proficient in that language.

Whatever be the current trend on Linked-In, at the end of the day the product development life cycle remains quite the same.

Still, as developers which general domains in software do you think would flourish in the near future?

My picks (not in order) -
>> Cyber security : automation, both offensive and defensive
>> Block chain : trustable data platforms
>> Applied AI : a few key models, applied to all niches, bettering existing UX
>> IOT : wearables, embeddables, smart appliances
>> AR : Navigation prompts, real time info about real life objects
>> VR : Immerse entertainment. (Metaverse 🤮)
>> Quantum computing : first gen costly commercial releases, new algos

What would you add or subtract from this?

[long confession/question]
So I was asked by a client to make an app similar to prisma(not exactly that but let's say a caricature app) and I knew I have to research a lot.

Now I have been loyal to PHP for over 5 years so I first tried with GD and imagick but the results were not very good, so I thought let's try opencv. I didn’t wanna make any compromises so I didn't go the bridging way, I worked on native python even though I am a newbie in it. I was fairly impressed with the cartoonizing results but others weren't. Soon I got to know that this would take much more than simple filter combinations or matrix manipulations.
I read about prisma and got to know it uses deep neural networks for the same.
Now, in the five years I have learnt almost all the things a run-of-the-mill "Full stack Web Developer" should know.
I have a fair knowledge of PHP, many of its frameworks, many js frameworks(obviously jquery), I have a very good understanding of CSS and its models, I have worked on some cool algos and found solutions to many problems but I haven't gotten to stage where I can implement neural networks/machine learning in my projects.
It just scares me.

A little back story: I have been the CTO of a small scale company for about 1.5 years now.

So all this got me to asking myself should I just step down from the post to a position where I can learn more skills. Managing takes a lot more time where I can't learn a lot. Sure I learnt some other important things but not as much tech knowledge as I would have in a more basic position.

I know not many of you must have read this far, but if you did what do you think I should do? Really depressed at the moment.

Multer is shit.

Do you know how to validate file size + mime type of the file before saving it to the disk?

Here is an instruction:

1. In one place you provide a it a fileFilter function that will validate the mime type, but this function can not validate file size or send user response.
2. In second place provide it a config limits file, that will validate file size, but can not validate mime type
3. In third place you provide middleware to capture any errors caused by previous 2 places and send response back to the user.
4. Go google for what is cb in multer because their shit documentation says nothing about it

Such simple thing as request->validation->response is split into 3 different parts, each of different type: callback, config file and middleware.

Why do so much people use this shit written by a braindead retarded morons?

Hi everyone !!
I'm new to coding community and but I learnt​ c++ in school. But I don't know how to improve on my skills. And what all should I learn to get an intern.
I tried codechef but I don't get it how to improve algos n data structures or any of it... N so much going like learn python or java ..make apps or build web pages .... It gets too much on my plate ...need suggestions how I pursue my self in improving competitive coding and alas build a career in web and Android with backend and front end to be precise a full stack developer .... Griefs apart "happy coding"

Vivaldi browser is shit.

Simple isntructions on how to make most shitty browser ever:

1. Force users to use "really-fucking-long" password that will not match to any of their existing ones.
2. Invent some useless stupid "encryption password" (why does any normal browser work fine without that shit) and most ridiculous - automatically set it to be the same as the main password.
3. Of course you forget the pass you set because you dont remember what symbol you added 5 times in the end of your normal pass to fit their stupid rules.
4. You have to reset it
5. "Encryption password" does not reset with it, so you still dont remember it
6. Sync is not working!
7. If you think this is shitty enought, you are not right - they went futher. To reset that fucking "encryption password" you have to... ERASE ALL YOUR CLOUD DATA.

Fucking retarded piece of shit - never, never trust those morons who made this shit browser to sync any of your sensitive information.

I just wanted to share it with my fellow devs,

I'm peacefully retiring from COMPETITIVE CODING. After two years of rigorous effort on CP, I don't think I improved a lot, although I learned some new DS and Algos. My bad that I assumed CP holds more importance than just being a sport.

It feels to me that I kinda wasted my two years, I could've spent it on some development or ML.

Now, I've started to realize that I can't think faster as other coders do. I tried a lot, but it's all dumped now. Maybe I'm not made for CP or maybe I simply suck at it.

Any sorta advice will be highly appreciated...

When run time error comes, I am like:- Try simple walk first and then run :p

Hey guys, i'v been working in a company for almost 1 year as a web developer. I only know the basic data structures and algorithms even after this year and also my co workers didn't seem to know graph,trees and other algos like dijikstra and all those advanced algo types. I'm searching for a job with better salary should I have to learn all these to get paid well ? Where even I can apply these things in my job? Is it worth ?
