Best sorting algorithm ever.
Sleep sort.
😂

Back in the days when I started to learn c I had an assignment to print all the prime numbers between 1 to 100 but didn't know how (with if/for/while)

So I searched Google for "prime numbers from 1 to 100" and used printf to print them on the screen

I got an A+

Ladies and gentlemen, prepare yourselves for a rant with a capital R, this is gonna be a long one.

Our story begins well over a year ago while I was still in university and things such as "professionalism" and "doing your job" are suggestions and not something you do to not get fired. We had multiple courses with large group projects that semester and the amount of reliable people I knew that weren't behind a year and in different courses was getting dangerously low. There were three of us who are friends (the other two henceforth known as Ms Reliable and the Enabler) and these projects were for five people minimum. The Enabler knew a couple of people who we could include, so we trusted her and we let them onto the multiple projects we had.

Oh boy, what a mistake that was. They were friends, a guy and a girl. The girl was a good dev, not someone I'd want to interact with out of work but she was fine, and a literal angel compared to the guy. Holy shit this guy. This guy, henceforth referred to as Mr DDTW, is a motherfucking embarrassment to devs everywhere. Lazy. Arrogant. Standards so low they're six feet under. Just to show you the sheer depth of this man's lack of fucks given, he would later reveal that he picked his thesis topic "because it's easy and I don't want to work too hard". I haven't even gotten into the meat of the rant yet and this dude is already raising my blood pressure.

I'll be focusing on one project in particular, a flying vehicle simulator, as this was the one that I was the most involved in and also the one where shit hit the fan hardest. It was a relatively simple-in-concept development project, but the workload was far too much for one person, meaning that we had to apply some rudimentary project management and coordination skills that we had learned to keep the project on track. I quickly became the de-facto PM as I had the best grasp on the project and was doing a lot of the heavy lifting.

The first incident happened while developing a navigation feature. Another teammate had done the basics, all he had to do was use the already-defined interfaces to check where the best place to land would be, taking into account if we had enough power to do so. Mr DDTW's code:
-Wasn't actually an algorithm, just 90 lines of if statements sandwiched between the other teammate's code.
-The if statements were so long that I had to horizontal scroll to see the end, approx 200 characters long per line.
-Could've probably been 20 normal-length lines MAX if he knew what a fucking for loop was.
-Checked about a third of the tiles that it should have because, once again, it's a series of concatenated if statements instead of an actual goddamn algorithm.
-IT DIDN'T FUCKING WORK!

My response was along the lines of "what the fuck is this?". This dipshit is in his final year and I've seen people write better code in their second semester. The rest of the team, his friend included, agreed that this was bad code and that it should be redone properly. The plan was for Mr DDTW to move his code into a new function and then fix it in another branch. Then we could merge it back when it was done. Well, he kept on saying it was done but:
-It still wasn't an algorithm.
-It was still 90 lines.
-They were still 200 characters wide.
-It still only checked a third of the tiles.
-IT STILL DIDN'T FUCKING WORK!

He also had one more task, an infinite loop detection system. He watched while Ms Reliable did the fucking work.

We hit our first of two deadlines successfully. We still didn't have a decent landing function but everything else was nice and polished, and we got graded incredibly well. The other projects had been going alright although the same issue of him not doing shit applied. Ms Reliable and I, seeing the shitstorm that would come if this dude didn't get his act together, lodged a complaint with the professor as a precautionary measure. Little did I know how much that advanced warning would save my ass later on.

Second sprint begins and I'm voted in as the actual PM this time. We have four main tasks, so we assign one person to each and me as a generalist who would take care of the minor tasks as well as help out whoever needed it. This ended up being a lot of reworking and re-abstracting, a lot of helping and, for reasons that nobody ever could have predicted, one of the main tasks.

These main tasks were new features that would need to be integrated, most of which had at least some mutual dependencies. Part of this project involved running our code, which would connect to the professor's test server and solve a server-side navigation problem. The more of these we solved, the better the grade, so understandably we needed an MVP to see if our shit worked on the basic problems and then fix whatever was causing the more advanced ones to fail. We decided to set an internal deadline for this MVP. Guess who didn't reach it?

Hitting the character limit, expect part 2 SOON

Thank you @dfox and @trogus, this is the best rant algorithm ever!

Graduation day:

A guy presents a modified pathfinding algorithm based on a*, in Java.
Jumping to the conclusions, he says he tested the algorithm on a 128x128 graph based maze, but not larger because the program saturates his 4 GB ram pc.

One teacher (algorithms and data structures) literally jumps from the chair "you saturate 4gb of ram with a* on 128x128 graph?!"

Best graduation day ever lol

So I have been a fly on the "wall" for last couple of months and never signed up, but now here I am!

Rant is about a serious topic - gender gap in tech industry!!
Couple of months ago Stackoverflow announced developer survey results! I was shocked by demographics results! It was disappointing to see biggest gender gap in general tech industry!
I believe tech industry can be the first one to have equal pay for women!

However.... (bad part)
I was going through my twitter feeds and saw this! Many of you have seen this tweet too.

(ohh!fuck I cant attach multiple images here, I should have created Medium post, fuck it!)

"They" continue, quoting from the tweet.
1)"....bias in society is reflected in AI"
2) "However, I do think it is our responsibility as designers/developers/users to be aware of this bias and do our best to correct it."

I want to rant about 2nd one. Some of you may not like it including grammar naziz!
As a developer/programmer I take 2nd one personally! I am currently at denial phase though!
And I have an OCD so gonna make points here!

1) Seriously tell me please, how the fuck you can write gender bias algorithm which can pass a big crazy amount of test suite?

2) Google has done many things for last decade to overcome gender gap related issues. I have met some of the nicest people from Google, and this is really hard for me to believe that google AI or that team has anything to do with the results!

3) Someone suggests use "they" in google translated result, can you fucking imagine how wrong that would be??? If I am developer working on that algo or even in that team and I see this ticket in jira with highest priority where it says, "make all translated results gender neutral using only they" - I would fucking like to die and may be in my next life ask me to do that, when I am a toddler!

4) I am an advocate for equal pay, equal rights and equal opportunities for everyone to "minify" this gender gap in tech, but showing google translate results of a gender natural language to make a point is wrong, it is simply undermining the efforts of something really helpful thing.

5) Moving on to the core point - What can be done to lower down the gender gap? I have seen amazing women who can code/manage far far far better than what I ever could imagine, and they are at really good place and deserve to be there. Are they doing enough to inspire other women to join tech industry?
Collective efforts are very much required. And need to keep in consideration that tech industry is highly competitive roles are also changing rapidly.

6) Many big companies have women at higher positions(CEO, CFO,....) what are their efforts to bring more women in tech industry?
(Some of you may not like this, as this is implying that it isn't only men's job. )

7) Going slightly political here, everyday we see really disappointing news related to women and their rights and health, I strongly believe women don't have to ask for or even have to mention about "equal rights" about anything. Everyone is equal!!!
This is 2017 and still fucked up!

Thats all for today! Heading for breakfast!

Hmm. So have you ever argued in a job interview? Like really standing your ground? In a technical interview?

Today I had a live coding session with a company I'm interested in. The developer was giving me tasks to evolve the feature on and on.

Everything was TDD. Splendid!

However at one point I had to test if the outcome of the method call is random. What I did is basically:
```
Provider<String> provider = new SomeProvider("aaa", "bbb", "ccc", "ddd", "eee", "fff")

for(int i=0; i<100; i++) {
String str = provider.get();
map.put(str, incrementCount(str));
}
Set<Integer> occurences = new HashSet(map.values());
occurences.removeIf(o -> o.equals(occurences.get(0)));
assertFalse(occurences.empty());
```
and I called it good enough, since I cannot verify true randomness.
But the dev argued that this is not enough and I must verify whether the output is truly random or not, and the output (considering the provider only has a finite set of values to return) occurences are almost equal (i.e. the deviation from median is the median itself).

I argued this is not possible and it beats the core principle of randomness -- non-determinism. Since if you can reliably test whether the sequence is truly random you must have an algorithm which determines what value can or cannot be next in the sequence. Which means determinism. And that the (P)RNG is then flawed. The best you can do is to test whether randomness is "good enough" for your use case.

We were arguing and he eventually said "alright, let's call it a good enough solution, since we're short on time".

I wonder whether this will have adverse effect my evaluation . So have you ever argued with your interviewer? Did it turn out to the better or to the worse?

But more importantly, was I right? :D

So technical interview today but woke up (6am) and started thinking about it and it led to this rant about algorithms. This is probably going into a Medium post if I ever get around to finishing it but sort of just wanted to share the rant that literally just went off in my mind.

*The problem with Algorithms Technical Interviews Is They don't test Real skills*

Real world problems are complex and often cross domain combining experience in multiple areas. Often the best way is not obvious unless you're a polymath and familiar with different areas, paradigms, designs. And intuitively can understand, reason, and combine them.

I don't think this is something a specific algorithm problem is designed to show. And the problem is the optimal solution to some of these and to algorithm design itself is that unless you train for it or are an algorithm designer (practice and experience), you can only brute force it in the amount of time given.

And quite frankly the algorithms I think we rely on daily weren't thought of in 30 minutes. The designers did this stuff for a living, thought about these problems for days and several iterations… at least. A lot were mathematicians. The matrix algorithm that had a Big O of 7N required a flash of insight that only someone constantly looking and thinking about the equations could see.

TBA
-system design
-clean readable coding practices
...

TLDR: I could probably go on and on about this stuff for hours jumping from item/example/area to the next and back again... But I don't think you can test these (~20) years of experience in a 1 hr technical interview focused on algorithms...

Best conversation with non tech roommate ever:

Me: hey roomie, implement an algorithm to determine if a string has all unique characters

Roommate: like a string of code or a string of yarn?

Some people of devRant are astonishingly stupid.

I post a rant of Ryan Dahl where he says he don't like the unnecessary complexity of modern software. It's an obvious UX rant, but @Crost says that it's about rushing releases and writing sloppy code to "tick the item off my list and solve the problem". @Crost and other boubas, if Ryan's vision was more widespread, macOS, the OS you all hate so much, wouldn't have existed because Linux would have the best UX ever.

I post a rant about Google algo being nasty and throwing triggering shit at me. I previously posted stuff like this, Root confirmed that it works just the way I think it works, it's a manipulative piece of crap. But @Oktokolo says that "The algorithm literally just gives you same of the stuff you just saw", well, I don't know, nice view of the problem for a guy with no computer and no smartphone, @Oktokolo! All that "youtube recommendations gathered us together on some obscure video" comments, and you still don't get it.

I post a rant about how I redesigned a fucking color wheel icon. It shows a "before-after" pic and the colors are obviously the same, but fucking @Oktokolo be popping up again, telling me that I have eye condition (!) that makes me see more blues than yellows.

No wonder you guys don't know how to use CSS, the simplest programming language (yes, it's a programming language).

No wonder smart people like SortOfTested just leave.

I still refuse to believe that devRant user base consists of stupid people exclusively. Perhaps they are just average, and I'm the genius with my Aspergers just getting way more information out of my environment like I always do.

This started as an update to my cover story for my Linked In profile, but as I got into a groove writing it, it turned into something more, but I’m not really sure what exactly. It maybe gets a little preachy towards the end so I’m not sure if I want to use it on LI but I figure it might be appreciated here:

In my IT career of nearly 20 years, I have worked on a very wide range of projects. I have worked on everything from mobile apps (both Adroid and iOS) to eCommerce to document management to CMS. I have such a broad technical background that if I am unfamiliar with any technology, there is a very good chance I can pick it up and run with it in a very short timespan.

If you think of the value that team members add to the team as a whole in mathematical terms, you have adders and you have subtractors. I am neither. I am a multiplier. I enjoy coaching, leading and architecture, but I don’t ever want to get out of the code entirely.

For the last 9 years, I have functioned as a technical team lead on a variety of highly successful and highly productive teams. As far as team leads go, I tend to be a bit more hands on. Generally, I manage to actively develop code about 25% of the time to keep my skills sharp and have a clear understanding of my team’s codebase.

Beyond that I also like to review as much of the code coming into the codebase as practical. I do this for 3 reasons. I do this because as a team lead, I am ultimately the one responsible for the quality and stability of the codebase. This also allows me to keep a finger on the pulse of the team, so that I have a better idea of who is struggling and who is outperforming. Finally, I recognize that my way may not necessarily be the best way to do something and I am perfectly willing to admit the same. I have learned just as much if not more by reviewing the work of others than having someone else review my own.

It has been said that if you find a job you love, you’ll never work a day in your life. This describes my relationship with software development perfectly. I have known that I would be writing software in some capacity for a living since I wrote my first “hello world” program in BASIC in the third grade.

I don’t like the term programmer because it has a sense of impersonality to it. I tolerate the title Software Developer, because it’s the industry standard. Personally, I prefer Software Craftsman to any other current vernacular for those that sling code for a living.

All too often is our work compiled into binary form, both literally and figuratively. Our users take for granted the fact that an app “just works”, without thinking about the proper use of layers of abstraction and separation of concerns, Gang of Four design patterns or why an abstract class was used instead of an interface. Take a look at any mediocre app’s review distribution in the App Store. You will inevitably see an inverse bell curve. Lot’s of 4’s and 5’s and lots of (but hopefully not as many) 1’s and not much in the middle. This leads one to believe that even given the subjective nature of a 5 star scale, users still look at things in terms of either “this app works for me” or “this one doesn’t”. It’s all still 1’s and 0’s.

Even as a contributor to many open source projects myself, I’ll be the first to admit that have never sat down and cracked open the Spring Framework to truly appreciate the work that has been poured into it. Yet, when I’m in backend mode, I’m working with Spring nearly every single day.

The moniker Software Craftsman helps to convey the fact that I put my heart and soul into every line of code that I or a member of my team write. An API contract isn’t just well designed or not. Some are better designed than others. Some are better documented than others. Despite the fact that the end result of our work is literally just a bunch of 1’s and 0’s, computer science is not an exact science at all. Anyone who has ever taken 200 lines of Java code and reduced it to less than 50 lines of reactive Kotlin, anyone who has ever hit that Utopia of 100% unit test coverage in a class, or anyone who can actually read that 2-line Perl implementation of the RSA algorithm understands this simple truth. Software development is an art form. I am a Software Craftsman.

Thought this algorithm keenly, it's like the best way I could or it could ever be done (in my head)...
there is no way this is going to fail

Then it fails terribly 😡😡

These are the times you feel like changing your career then un-installing devRant
