29-year veteran here. Began programming professionally in 1990, writing BASIC applications for an 8-bit Apple II+ computer. Learned Pascal, C, Clipper, COBOL. Ironic side-story: back then, my university colleagues and I used to make fun of old COBOL programmers. Fortunately, I never had to actually work with the language, but the knowledge allowed me to qualify for a decent job position, back in '92.

For a while, I worked with an IBM mainframe, using REXX and EXEC2 scripting languages for the VM/SP operating system. Then I began programming for the web, wrote my first dynamic web applications with cgi-bin shell and Perl scripts. Used the little-known IBM Net.Data scripting language. I finally learned PHP and settled with it for many, many years.

I always wanted to be a programmer. As a kid I dreamed of being like Kevin Flynn, of TRON - create world famous videogames and live upstairs my own arcade place! Later on, at some point, I was disappointed, I questioned my skills, I thought I should do more, I let other people's expectations make feel bad. Then I finally realized I actually enjoy a quieter, simpler life. And I made peace with it.

I'm now like the old programmers I used to mock 30 years ago. There's so much shit inside my brain. And everything seems so damn complex these days. Frameworks, package managers, transpilers, layers and more layers of code. I try to keep up. And the more I learn, the more it seems I don't know.

Sometimes I feel tired. Yet, I still enjoy creating things and solving problems with programming. I still have fun learning. And after all these years, I learned to be proud of my work, even if it didn't turn out to be as glamorous as in the movies.

It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.

In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.

Languages without a fully implemented type system.

Granted, it has been a fad for a quarter century, but everything points at one simple fact: Types matter in programming.

In dynamic languages, you tend to see that testing suites explode into thousands of tests, many of which wouldn't even be necessary if you had some type safety.

You see that languages like JS are forked into more typesafe dialects, like Typescript. Python got typehints since 3.6, and PHP added typehints for methods, then typehints for properties, and will soon even have compound types.

Maybe most languages will never reach the level of Haskell or Scala, and that's totally fine, but I think the direction languages are moving in is pretty much set in stone: No ambiguity, more safety. Code should fail before deploying, not after.

You know what's the difference between
- static page written purely in HTML with inline styling
and
- dynamic page generated in PHP, that actually loads data from MySQL database and is correctly styled in separate CSS document
on national level exam necessary to earn a title of technician?
ONE HACKING PERCENT!

Ok, backstory. So, few days ago I got results from that exam. To be honest, it was very, very easy so I wasn't worried at all, unlike some of my classmates who just don't understand programming at all (you need at least 75% to pass). Our task was to create database, write website in PHP that shows contents of that database and use CSS to give it a look that of example web page and run it on XAMPP. I've got result of 96% and while I was wandering what I've done wrong i hear my colleague almost screaming with joy "I passed! And I haven't even touched PHP. I was soooo sure I'll fail." So I asked him what's his result and he says 95%. And then another colleague said he got 95% without PHP. So, in other words what I thought to be the main task was worth 1%. Apparently, what was more important was for the page to look identical to the example, so I guess some examiners didn't even look into the source. And don't get me wrong, I don't wish my classmates had failed. That's not why I'm ranting. But why in the name of Ada Lovelace the task said to use PHP and all that if it weren't supposed to check our knowledge of programming in PHP? Sometimes I think the people who design these tests don't even know what they're doing.

I'm drunk and I'll probably regret this, but here's a drunken rank of things I've learned as an engineer for the past 10 years.

The best way I've advanced my career is by changing companies.

Technology stacks don't really matter because there are like 15 basic patterns of software engineering in my field that apply. I work in data so it's not going to be the same as webdev or embedded. But all fields have about 10-20 core principles and the tech stack is just trying to make those things easier, so don't fret overit.

There's a reason why people recommend job hunting. If I'm unsatisfied at a job, it's probably time to move on.

I've made some good, lifelong friends at companies I've worked with. I don't need to make that a requirement of every place I work. I've been perfectly happy working at places where I didn't form friendships with my coworkers and I've been unhappy at places where I made some great friends.

I've learned to be honest with my manager. Not too honest, but honest enough where I can be authentic at work. What's the worse that can happen? He fire me? I'll just pick up a new job in 2 weeks.

If I'm awaken at 2am from being on-call for more than once per quarter, then something is seriously wrong and I will either fix it or quit.

pour another glass

Qualities of a good manager share a lot of qualities of a good engineer.

When I first started, I was enamored with technology and programming and computer science. I'm over it.

Good code is code that can be understood by a junior engineer. Great code can be understood by a first year CS freshman. The best code is no code at all.

The most underrated skill to learn as an engineer is how to document. Fuck, someone please teach me how to write good documentation. Seriously, if there's any recommendations, I'd seriously pay for a course (like probably a lot of money, maybe 1k for a course if it guaranteed that I could write good docs.)

Related to above, writing good proposals for changes is a great skill.

Almost every holy war out there (vim vs emacs, mac vs linux, whatever) doesn't matter... except one. See below.

The older I get, the more I appreciate dynamic languages. Fuck, I said it. Fight me.

If I ever find myself thinking I'm the smartest person in the room, it's time to leave.

I don't know why full stack webdevs are paid so poorly. No really, they should be paid like half a mil a year just base salary. Fuck they have to understand both front end AND back end AND how different browsers work AND networking AND databases AND caching AND differences between web and mobile AND omg what the fuck there's another framework out there that companies want to use? Seriously, why are webdevs paid so little.

We should hire more interns, they're awesome. Those energetic little fucks with their ideas. Even better when they can question or criticize something. I love interns.

sip

Don't meet your heroes. I paid 5k to take a course by one of my heroes. He's a brilliant man, but at the end of it I realized that he's making it up as he goes along like the rest of us.

Tech stack matters. OK I just said tech stack doesn't matter, but hear me out. If you hear Python dev vs C++ dev, you think very different things, right? That's because certain tools are really good at certain jobs. If you're not sure what you want to do, just do Java. It's a shitty programming language that's good at almost everything.

The greatest programming language ever is lisp. I should learn lisp.

For beginners, the most lucrative programming language to learn is SQL. Fuck all other languages. If you know SQL and nothing else, you can make bank. Payroll specialtist? Maybe 50k. Payroll specialist who knows SQL? 90k. Average joe with organizational skills at big corp? $40k. Average joe with organization skills AND sql? Call yourself a PM and earn $150k.

Tests are important but TDD is a damn cult.

Cushy government jobs are not what they are cracked up to be, at least for early to mid-career engineers. Sure, $120k + bennies + pension sound great, but you'll be selling your soul to work on esoteric proprietary technology. Much respect to government workers but seriously there's a reason why the median age for engineers at those places is 50+. Advice does not apply to government contractors.

Third party recruiters are leeches. However, if you find a good one, seriously develop a good relationship with them. They can help bootstrap your career. How do you know if you have a good one? If they've been a third party recruiter for more than 3 years, they're probably bad. The good ones typically become recruiters are large companies.

Options are worthless or can make you a millionaire. They're probably worthless unless the headcount of engineering is more than 100. Then maybe they are worth something within this decade.

Work from home is the tits. But lack of whiteboarding sucks.

Dynamic programming languages be like

No programming necessary for this dynamic pie chart...

How to land a programming job

1. ABC (Always Be Coding) - The more you code, the better you'll get.

2. Master at least one multi-paradigm language - Some good candidates are C#, C++, Java, PHP, Python, and Ruby.

3. Re-invent the wheel - You should implement the most common data structures in your language choice.

4. Solve word problems - Pick those that test your ability to implement recursive, pattern-matching, greedy, dynamic programming, and graph problems

5. Make coding easy - At least, make it look easy.

6. Be passionate - If you don't care, then nobody else will.

7. Don't make assumptions - Ask questions if you're not sure.

$Me: *whispers* Do you like it rough baby?

$Her: *moans* uhuh

$Me: *continues whispering* I'm gonna implement a dynamic programming algorithm for you.

$Her: ahhhhhhh yaass *looses control of her body*

Fictional scenario of course I'd never implement shit for nobody who isn't paying.

Sometimes.....

When I want to escape how dull/repetitive/boring the world of web development is. I crack open a nice lil terminal, dust off my gcc/g++ compilers and fuck around in C or C++ till my eyes start to bleed.

I have been fucking around with systems development. Mainly with Linux programming. I have also started to get deeper on game engine design and compiler design....because low level development is where its at.

A man can only fuck around rest apis, css and html and the endless sea of Javascript and other dynamic languages for so long before going crazy.

Eventually.....I would want to code something impressive enough to give me a spot somewhere as a C or C++ developer. I just can't work with web development any longer man. It really is not what I want to do, the fact that I do it(and that I am good at it) is circumstantial more than because I really enjoy it. I really don't

Hello everyone, this is my first time here so hi! I want to tell you all a story about my current situation.

At 18 while in the military I was able to get my first computer, it was a small hp pavilion laptop with windows 7. The system would crash constantly, even though I would only use it for googling stuff and using fb to talk to people. 5 months after I got it and continuously hated it decided to find out why and who could I blame (other than myself) for the system making me do the ctrl alt del dance all the time....

Found out that there are people called computer programmers that made software. Decided to give it a go since I had some free time most days. Started out with c++ because it was being recommended in some websites. Had many "oh deeeeer lord" moments. After not getting much traction I decided to move to Java which seemed like an easier step than C++. Had fun, but after some verbosity I decided to move into more dynamic lands. Tried JS and since at the time there was no Node and I was not very into the idea of building websites I decided to move into Python, Ruby, PHP and Perl and had a really great time using and learning all of them. I decided to get good in theoretical aspects of computer programming and since I had a knack for math I decided to get started with basic computer science concepts.

I absolutely frigging loved it. And not only that, but learning new things became an obsession, the kind that would make me go to bed at 02:40 am just to wake up at 04:00 or 06:00 because the military is like that. I really wanted to absorb as much as I could since I wanted to go to college for it and wanted to be prepared since I did not wanted to be a complete newb. Took Harvard CS50, Standford Programming 101 with Java, Rice's Python course and MIT's Python programming class. I had so much fun I don't regret it one bit.
By the time I got to college I had already made the jump to Linux and was an adept Arch user, Its not that it was superior or anything, but it really forced me to learn about Linux and working around a terminal and the internals of the system to get what I want. Now a days I settle for Fedora or Debian based systems since they are easier and time is money.

Uni was a breeze, math was fun and the programming classes seemed like glorified "Hello World" courses. I had fun, but not that much fun, most of my time was spent getting better at actual coding. I am no genius, nor my grades were super amazing(I did graduate with honors though) but I had fun, which never really happened in school before that.

While in school I took my first programming gig! It was in ASP.NET MVC, we were using C#, I got the job through a customer that I met at work, I was working in retail during the time and absolutely hated it. I remember being so excited with the gig, I got to meet other developers! Where I am from there aren't that many and most of them are very specialized, so they only get concerned with certain aspects of coding (e.g VBA developers.....) and that is until I met the lead dev. He was by far one of the biggest assholes I had ever met in my life. Absolutely nothing that I would do or say made hem not be a dick. My code was steady, but I would find bugs of incomplete stuff that he would do, whenever I would fix it he would belittle me and constantly remind me of my position as a "junior dev" in the company saying things as "if you have an issue with my code or standards tell me, but do not touch the code" which was funny considering that I would not be able to advance without those fixes. I quit not even 3 months latter because I could not stand the dick, neither 2 of the other developers since the immediately resigned after they got their own courage.

A year latter I was able to find myself another gig. I was hesitant for a moment since it was another remote position in which I had already had a crappy experience. Boy this one was bad. To be fair, this was on me since I had to get good with Lumen after only having some exposure to Laravel. Which I did mentioned repeatedly even though he did offer to train me in order to help him. Same thing, after a couple of weeks of being told how much I did not know I decided to get out.

That is 2 strikes.

So I waited a little while and took a position inside another company that was using vanilla PHP to build their services. Their system was solid though, the lead engineer remains a friend and I did learn a lot from him. I got contracted because they were looking for a Java developer. The salary was good. But when I got there they mentioned that they wanted a developer in Java...to build Android. At the time I was using Java with Spring so I though "well how hard can this be! I already use Android so the love for the system is there, lets do this!" And it was an intense, fun and really amazing experience.

-- To be continued.

I hope computing heavens have:

-One brand of hardware
-One OS
-One browser
-No closed source software
-No ads
-One monitor aspect ratio
-One fucking programming language with a fucking big standard library.
-Phones are just the same exactly the same OS as in computer, not stupid adaptations.
-All pages are only HTML/CSS, without JS.
-Due there is one browser and one OS, when you need a dynamic page, you can display a desktop app in the browser downloading its binary.
-There are one fucking brand on printer with standard drivers which are included in the OS.

We are so far from heaven

...
Me: Oh cool, So you do dynamic websites
Him: Yes,
Me: Oh Great, What programming language do you use?
Him: Oh huu, I use Sublime Text...

Sorry, I didn't heard the rest cause I was dead

Found this on one of the medium posts today :P

"Those who cannot remember the past are condemned to repeat it."

--Dynamic Programming

I've been coding for over 8 years, and whenever a recruiter says we have you do these coding challenges or recite them an algorithm from memory, I say "You know, the longer you've been programming, the less you remember how to do this stuff, because you don't use it in real life." They say, "Well we just want to see how you think and how you solve problems." B.S.
These types of algorithmic programming challenges besides the simpler ones don't show how you think. A lot of stuff like the dynamic programming and other optimization problems were solved by phd professors after many years of research. Nobody would think up these solutions on their own.
These programming challenges weed out
experienced developers unless they want to
take the time to re-learn this stuff. It explains why google, facebook or amazon are filled with young and inexperienced developers and how come it takes so many thousands of them to get anything done, and they still have buggy products...

If programming languages were countries, which country would each language represent?

Disclaimer: its just a joke

Java: USA -- optimistic, powerful, likes to gloss over inconveniences.

C++: UK -- strong and exacting, but not so good at actually finishing things and tends to get overtaken by Java.

Python: The Netherlands. "Hey no problem, let'sh do it guysh!"

Ruby: France. Powerful, stylish and convinced of its own correctness, but somewhat ignored by everyone else.

Assembly language: India. Massive, deep, vitally important but full of problems.

Cobol: Russia. Once very powerful and written with managers in mind; but has ended up losing out.

SQL and PL/SQL: Germany. A solid, reliable workhorse of a language.

Javascript: Italy. Massively influential and loved by everyone, but breaks down easily.

Scala: Hungary. Technically pure and correct, but suffers from an unworkable obsession with grammar that will limit its future success.

C: Norway. Tough and dynamic, but not very exciting.

PHP: Brazil. A lot of beauty springs from it and it flaunts itself a lot, but it's secretly very conservative.

LISP: Iceland. Incredibly clever and well-organised, but icy and remote.

Perl: China. Able to do apparently almost anything, but rather inscrutable.

Swift: Japan. One minute it's nowhere, the next it's everywhere and your mobile phone relies on it.

C#: Switzerland. Beautiful and well thought-out, but expect to pay a lot if you want to get seriously involved.

R: Liechtenstein. Probably really amazing, especially if you're into big numbers, but no-one knows what it actually does.

Awk: North Korea. Stubbornly resists change, and its users appear to be unnaturally fond of it for reasons we can only speculate on.

WHY DO WE HAVE TO BUY THE PROFESSOR'S BOOK JUST TO BE ABLE TO PASS THE COURSE?

It's so stupid, I'm currently attending a Operating Systems course at university and the professor NEEDS us to buy his book because all of the tasks and seminars are based on his book. It is stupid! There are thousands of books out there on Operating Systems programming! Free ones too! But instead we have to spend 800SEK (100USD) on his book.

And guess what? There is literally one task based on his book... To summarize the chapters about Fixed Priority scheduling and Dynamic Priority scheduling. Which is 15 pages out of 200+.

All the students attending the course are going to the director of studies and complaining next week. This is unacceptable. If it was a good book, sure. But the book has the same exact information as multiple free e-books we've found.

Ridiculous.

After months of studying dynamic programming, I can finally say with confidence that I UNDERSTAND NOTHING.

This is my silent protest

First story (not rant) :3

So I was asked to set problems for an online programming contest for my college (I'm a sophomore)

The participants were students from my college.

Teacher told me "make as hard as you can"

I gave it my all.

:|

1 person solved the first question. Nobody solved the other four. :|

Not sure if I should be proud or sad.

And if you're wondering - here was my first question -

Sam wants to invest in real estate. He's got X dollars to spend. He knows the expected value per square meter of a given property. He knows the coordinates of the vertices of the polygon shaped properties he's interested in.

(both the values and coordinates for each property are given in input)

Find the maximum return on investment he can get.

(answer is, basically you calculate the area of each polygonal house using half the vector cross product, multiply it with their expected value per square meter, and then apply a dynamic programming - knapsack approach)

;-; I really thought it was a nice question man. ;-; I put so much thought into others too. ;-;

Got ignored. ;-;

Yeaaahhh that moment when the program flawlessly crunches through ten thousands of files, only limited by the slowish HDD! :-)

In full multi-threading, tons of dynamic buffer resizing, pointer shit left and right, also two star programming, and everything written in raw C!

Going through the typical phase of being depressed because of feeling underdeveloped skill wise and ignorant knowledge wise; despite how much I learn. God, spent 3 days on a recursive dynamic programming problem and couldn't implement it right... then I decided to glance at someones solution on github and turns out he did what I couldn't do in 70+ lines of code in 20. Sigh, just want to right concise and clear code and become a better programmer all together, but that obviously takes time. For the mean time I am feeling quite defeated.

I really like this book on the basis of the philosophy overall, no this doesn’t solve all problems but it’s a good baseline of “guidelines/rules” to program by. Good metrics or goals to architect and design software projects high and low level projects.

Fight Software Rot
Avoid duplicate code
Write Flexible, dynamic, adaptable code
Not cargo cult programming and programming by coincidence.
Make robust code, contracts/asserts/exceptions
Test, Test, and TEST again and Continue testing.. this is a big one.. not so much meaning TDD.. but just testing in general never stop trying to break your software.. FIND the bugs.. you should want to find your bugs. Even after releasing code the field continue testing.

Create a new, fast, strictly typed programming language with organized project structure, normal package manager, dynamic syntax extensions (that means you can change the syntax of the language if you like!) and (most importantly) if statements which are written like this:
(bananas == 0) -> print 'No bananas!';

When I was in college OOP was emerging. A lot of the professors were against teaching it as the core. Some younger professors were adamant about it, and also Java fanatics. So after the bell rang, they'd sometimes teach people that wanted to learn it. I stayed after and the professor said that object oriented programming treated things like reality.

My first thought to this was hold up, modeling reality is hard and complicated, why would you want to add that to your programming that's utter madness.

Then he started with a ball example and how some balls in reality are blue, and they can have a bounce action we can express with a method.

My first thought was that this seems a very niche example. It has very little to do with any problems I have yet solved and I felt thinking about it this way would complicate my programs rather than make them simpler.

I looked around the at remnants of my classmates and saw several sitting forward, their eyes lit up and I felt like I was in a cult meeting where the head is trying to make everyone enamored of their personality. Except he wasn't selling himself, he was selling an idea.

I patiently waited it out, wanting there to be something of value in the after the bell lesson. Something I could use to better my own programming ability. It never came.

This same professor would tell us all to read and buy gang of four it would change our lives. It was an expensive hard cover book with a ribbon attached for a bookmark. It was made to look important. I didn't have much money in college but I gave it a shot I bought the book. I remember wrinkling my nose often, reading at it. Feeling like I was still being sold something. But where was the proof. It was all an argument from authority and I didn't think the argument was very good.

I left college thinking the whole thing was silly and would surely go away with time. And then it grew, and grew. It started to be impossible to avoid it. So I'd just use it when I had to and that became more and more often.

I began to doubt myself. Perhaps I was wrong, surely all these people using and loving this paradigm could not be wrong. I took on a 3 year project to dive deep into OOP later in my career. I was already intimately aware of OOP having to have done so much of it. But I caught up on all the latest ideas and practiced them for a the first year. I thought if OOP is so good I should be able to be more productive in years 2 and 3.

It was the most miserable I had ever been as a programmer. Everything took forever to do. There was boilerplate code everywhere. You didn't so much solve problems as stuff abstract ideas that had nothing to do with the problem everywhere and THEN code the actual part of the code that does a task. Even though I was working with an interpreted language they had added a need to compile, for dependency injection. What's next taking the benefit of dynamic typing and forcing typing into it? Oh I see they managed to do that too. At this point why not just use C or C++. It's going to do everything you wanted if you add compiling and typing and do it way faster at run time.

I talked to the client extensively about everything. We both agreed the project was untenable. We moved everything over another 3 years. His business is doing better than ever before now by several metrics. And I can be productive again. My self doubt was over. OOP is a complicated mess that drags down the software industry, little better than snake oil and full of empty promises. Unfortunately it is all some people know.

Now there is a functional movement, a data oriented movement, and things are looking a little brighter. However, no one seems to care for procedural. Functional and procedural are not that different. Functional just tries to put more constraints on the developer. Data oriented is also a lot more sensible, and again pretty close to procedural a lot of the time. It's just odd to me this need to separate from procedural at all. Procedural was very honest. If you're a bad programmer you make bad code. If you're a good programmer you make good code. It seems a lot of this was meant to enforce bad programmers to make good code. I'll tell you what I think though. I think that has never worked. It's just hidden it away in some abstraction and made identifying it harder. Much like the code methodologies themselves do to the code.

Now I'm left with a choice, keep my own business going to work on what I love, shift gears and do what I hate for more money, or pivot careers entirely. I decided after all this to go into data science because what you all are doing to the software industry sickens me. And that's my story. It's one that makes a lot of people defensive or even passive aggressive, to those people I say, try more things. At least then you can be less defensive about your opinion.

I want to explain to people like ostream (aka aviophille) why JS is a crap language. Because they apparently don't know (lol).

First I want to say that JS is fine for small things like gluing some parts togeter. Like, you know, the exact thing it was intended for when it was invented: scripting.

So why is it bad as a programming language for whole apps or projects?

No type checks (dynamic typing). This is typical for scripting languages and not neccesarily bad for such a language but it's certainly bad for a programming language.

"truthy" everything. It's bad for readability and it's dangerous because you can accidentaly make unwanted behavior.

The existence of == and ===. The rule for many real life JS projects is to always use === to be more safe.
In general: The correct thing should be the default thing. JS violates that.

Automatic semicolon insertion can cause funny surprises.
If semicolons aren't truly optional, then they should not be allowed to be omitted.

No enums. Do I need to say more?

No generics (of course, lol).

Fucked up implicit type conversions that violate the principle of least surprise (you know those from all the memes).

No integer data types (only floating point). BigInt obviously doesn't count.

No value types and no real concept for immutability. "Const" doesn't count because it only makes the reference immutale (see lack of value types). "Freeze" doesn't count since it's a runtime enforcement and therefore pretty useless.

No algebraic types. That one can be forgiven though, because it's only common in the most modern languages.

The need for null AND undefined.

No concept of non-nullability (values that can not be null).

JS embraces the "fail silently" approach, which means that many bugs remain unnoticed and will be a PITA to find and debug.

Some of the problems can and have been adressed with TypeScript, but most of them are unfixable because it would break backward compatibility.
So JS is truly rotten at the core and can not be fixed in principle.

That doesn't mean that I also hate JS devs. I pity your poor souls for having to deal with this abomination of a language.

It's likely that I fogot to mention many other problems with JS, so feel free to extend the list in the comments :)

Marry Christmas!

well fuck me, just spent the whole weekend (about 33 hrs) not being able to solve a task from uni with a java program we had to write🙄😪

the problem was a given set of movies with a weekday, the begin time, the duration, the title, and a "score"
the movies take place in one week (random days, random amount of movies) and every movie can be shown multiple times
our task was to find a sequence of non-overlapping (all unique) movies with a score of at least a given number
all in text form

i tried dynamic programming but the more i tried, the more it got complicated, so i ended up using "earliest finishing time first"
my code is just 3 points under the goal and i don't know what to change anymore😒, also some friends did the exact same and succeeded somehow
copying (and obfuscating) won't work, as the codes will be compared by a very good "copy checker"
let's hope i'll still have a chance for an exam😐

First day of web server programming class. The teacher clearly doesn't know anything. He doesn't even know what the course is about! When someone asks him what it is, he mumbles about "dynamic" something... Then he says we will be using the languages JavaScript, MVC, and PHP. What the fuck. MVC? LANGUAGE?

He then tries to come up with some project we could make, and is not going to teach anything apparently. Keep in mind, most people in this class have very little previous experience with programming.

After not saying anything for a long time, he finally tells us to make a clock in JavaScript. A CLOCK. He is supposed to teach how to make Web APIs and such, but instead, he tells us to make a clock in JavaScript, and that's it.

What. The. Fuck.

For skilled mid-career engineers, dynamic programming problems, np-complete bar raisers.

For new engineers, simple questions that can't be taught in school (questions that require business prioritization)

For older engineers, questions they haven't done since college (big-O, writing algorithms from memory)

Today's rant: JavaScript's type system.

I realized halfway through that I can't happily call JavaScript a "programming language" so just assume
alias programming="scripting"

I'm sure it's not actually as frustrating as it seems to me. Thing is, I'm used to either statically-typed languages or dynamically-typed languages that actually make sense. If I were to try to add an integer to something I'd forgotten was a string in Python, it'd immediately tell me "look, buddy, do you want me to treat this as a concatenation or an addition? I have no idea the way you've got this written." I've found that mistakes are a common thing with dynamic typing. Maybe I'm just not experienced enough yet, maybe it's really as stupid as it looks. JavaScript just goes "hey look I'm gonna tack all of these guys together and make a weird franken-string like '$NaN34.$&' because that's absolutely what we want here!" Then I run my webpage and instead of a nice numeric total like I wanted, good old JavaScript just went "Yep, I have no idea what I'm doing here I'm just gonna drop this here and pretend it's right." Now absolutely I do not expect my programming language to make correct assumptions and read my mind, otherwise JavaScript would be programming me and not the other way around. But it could at least let me know that I had incompatible types going on rather than just shamelessly going along with what it's doing. Good GRIEF, man, some of the idiosyncrasies of the EMCAScript language definition itself just make me want to punch a horse.

Working on an Android app for a client who has a dev team that is developing a web app in with ember js / rails. These folks are "in charge" of the endpoints our app needs to function. Now as a native developer, I'm not a hater of a web apps way of doing things but with this particular app their dev teams seems to think that all programming languages can parse json as dynamically as javascript...

Exhibit A:

- Sample Endpoint Documentation
* GetImportantInfo
* Params: $id // id of info to get details of
* Endpoint: get-info/$id
* Method: GET
* Entity Return {SampleInfoModel}

- Example API calls in desktop REST client
* get-info/1
- response
{
"a" : 0,
"b" : false,
"c" : null
}
* get-info/2
- response
{
"a" : [null, "random date stamp"],
"b" : 3.14,
"c" : {
"z" : false,
"y" : 0.5
}
}
* get-info/3
- response
{
"a" : "false" // yes as a string
"b" : "yellow"
"c" : 1.75
}

Look, I get that js and ruby have dynamic types and a string can become a float can become a Boolean can become a cat can become an anvil. But that mess is very difficult to parse and make sense of in a stack that relies on static types.

After writing a million switch statements with cases like "is Float" or "is String" from kotlin's Any type // alias for java.Object, I throw my hands in the air and tell my boss we need to get on the phone with these folks. He agrees and we schedules a day that their main developer can come to our shop to "show us the ropes".

So the day comes and this guy shows up with his mac book pro and skinny jeans. We begin showing him the different data types coming back and explain how its bad for performance and can lead to bugs in the future if the model structure changes between different call params. He matter of factually has an epiphany and exclaims "OHHHHHH! I got you covered dawg!" and begins click clacking on his laptop to make sense of it all. We decide not to disturb him any more so he can keep working.

3 hours goes by...

He burst out of our conference room shouting "I am the greatest coder in the world! There's no problem I can't solve! Test it now!"

Weary, we begin testing the endpoints in our REST clients....

His magic fix, every single response is a quoted string of json:

example:
- old response
{
"foo" : "bar"
}
- new "improved" response
"{ \"foo\" : \"bar\" }"

smh....

I've spent a lot of time messing around with C, having struggled with object-oriented programming (due to not really knowing how best to structure things, not knowing when to apply certain design patterns).

When writing C code, I'd write OOP-esque code (pass around a struct to routines to do things with it) and enjoyed just making things happen without having to think too much about the overall design. But then I'd crave being able to use namespaces, and think about how the code would be tidier if I used exceptions instead of having every routine return an error code...

Working with Python and Node over the past couple of years has allowed me to easily get into OOP (no separate declaration/definition, loose typing etc.) and from that I've made some fairly good design decisions. I'd implemented a few design patterns without even realising which patterns they were - later reading up on them and thinking "hey, that's what I used earlier!"

I've also had a bit of an obsession with small executable files - using templates and other features of C++ add some bloat (on Windows at least) compared to C. There were other gripes I had with C++, mostly to do with making things modular (dynamic linking etc.) but really it's irrelevant/unreasonable.

And yes, for someone who doesn't like code bloat, working with Node is somewhat ironic... (hello, node_modules...)

So today I decided to revisit C++ and dust off my old copy of C++ in a Nutshell, and try to see if I could write some code to do things that I struggled with before. One nice thing is that this book was printed in 2003, yet all of its content is still relevant. Of course, there are newer C++ standards, but I can happily just hack away and avoid using anything that has been deprecated.

One thing I've always avoided is dynamic_cast because every time I read about it, I read that "it's slow". So I just tried to work around it when really if it's the right tool for the job, I might as well use it... It's really useful!

Anyway, now I've typed all this positivity about C++ I will probably find a little later on that I hit a wall with what I'm doing and give up again... :p

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

Changes colors in CSS and texts in HTML.

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

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

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

It's just absurd.

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

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

It's a sad fact of life that managing dynamic memory is a very difficult programming task. Some public domain X-Window applications are notorious for leaking like the Apple Computer board of directors -- Expert C Programming

So today, my friend (who is younger) has returned from a programming competition hosted by the district. The language used was Pascal. Before the competition my friend had been pretty confident about his skills of using Free Pascal, but after that, he has been different.
He came back in tears. I asked him what was happening in the computer room.
- Turbo Pascal.
I was stunned for seconds. Who the heck in this 2019 still uses an ancient compiler dated from the 1990s for the DOS operating system? And yet the competition's computers had only it installed. I think nowadays everyone learning Pascal, at the very least, uses Free Pascal as the IDE. I could immediately imagine how restrictive and frustrating was programming on such that thing.
- I couldn't create... dynamic arrays... so I had to declare two 30 000-element arrays (which was required by the problem), but when compiling... it said... the maximum heap size was 64KB.
It wouldn't let me use "exit(result)" (to return a function's result) so I wasted many minutes replacing them with "<function name> := result; exit;".

And many more problems.

Raise your hand if you think this is ridiculous.

Reading CLRS ~> Spend half hour reading how to cut rods to profit the most... I love Algorithms 😍😍😍😍

At this point of my side project I wanted to check out openresty for dynamic proxy creation in nginx.

Happy to check it out I installed centos 7 as guest using new command I just learned virt-builder that would automate vm creation.

Spend 10 hours debugging why I can ping and ssh but cannot get to application port from any network.

Checked iptables, restarted network, reinstalled vm again 3 times with different methods.
Scrolled trough whole internet and it’s mostly outdated problems.
Learned bunch of new commands without new results.

Results were always the same:
No route to host.

Turned out firewalld is fucking thing now.

systemctl firewalld stop helped

Now I know that systemd would kill me at some point for sure.

What I can add at this point ?

Please add more distros, differences, standards and programming languages so world definitely would be better place.
I need a short break now to actually start making shit that I wanted to start at 4-5pm on Saturday.
It’s Sunday 3:30am and time for breakfast.
At least I am happy it started working.

Since day 0, I have been fond of computers. One of my first plush was called "DataDog" and looked like a CRT screen with dog ears around. According to my mum I was "addicted" to it.

At year 2, my dad was arranging some music on some software while I was watching him on his lap. Quick jump to the present: nowadays and since 10 years I run my own home studio with three guitars, two keyboards, one bass, three monitors, a microphone, an amp and a cabinet... coincidence? I think not!

Fast forward 5 years later (so I'm 6-7 years old), and I was playing with the legendary pinball game on Win95, as well as Flight Simulator. Then I was hogging mum's laptop to play settlers II (<3 that game), I eventually got my computer, and got into Quake III Arena being aged 10 (and had to tell my mum that game was safe for my age haha - I eventually removed the blood effects).

The Quake 3 Arena chapter is interesting: it got me into router configuration as I wanted to open a port through the router to host my own dedicated games with friends, it got me into DNS configuration (I was running a no-DNS client that allowed friends to join me through a DNS while having a dynamic IP) and eventually... to modifying .cfg files to tune my server as I wanted it. No programming here but a nice intro into :)

Then I hated the fact everybody would point their finger at me and say "geek" - I was only 13, fragile, sensitive, and I wanted everything but a bad image on me.

Meanwhile I continued on getting interested in hardware and configure my own computers, and investing myself into music production.

Then, university. "What do you want to study?" I thought of everything but IT, fleeing the image of a "geek". Turns out it was a waste of time, and at 21 yo I got into web development (well, just html and css), then learned a bit of PHP, finally got a specialized 2-year training and now here I am!

I was bound to be in IT either way since day 0, and funny fact, I've used every windows edition since Win95.

We here in India are going through a nightmare. We have our CS syllabus from 1990s, we still write lab records, and solve 10 pineapples problem for placement training. Nobody really bothers about actual skill or knowledge, are like sheep behind feed. Passion is taken for granted and overruled by the “experts”.

A good education in CS starts from the hunger to solve problems that would matter to people. Future of CS education is in online courses that give out ideas to generate more ideas and inspire programming not as a subject but as a basic need of the hour. People should love the fact that CS is queer in many ways but is very powerful. Basics are important but the education must hold on to what is currently happening in the world.

World will be doomed when we start making students study the same thing what we did, except it is called Math. A subject has to be dynamic. If anybody agrees what I say, spread it so that world will understand what learning means...

An interviewer recently asked me "how many 'valid' combinations can you do with N parenthesis, either closing or opening?"

It sounds easy enough, yet I didn't manage to find the solution, apparently I was close enough using dynamic programming. Can you solve it ? :)

By any chance do anyone here know about Viterbi Search Algorithm?

so i did this nice tool with data structures, dynamic ui composing, input sanitizing, modularity and scalability with tidy and efficient javascript and useful css.

showing it to my boss: "cool what you can do with html". WAT?

(he is not a programmer but knows i´m into web-programming)

I'm angry that all dynamic programming problems seem the same yet, I still struggle to solve them.

Dynamic programming is like drinking. You look at it from the top down but it's solved by bottoms up.

I had a pretty good year! I've gone from being a totally unknown passionate web dev to a respected full stack dev. This will be a bit lengthy rant...
Best:
- Got my first full time employment dev role at a company after being self-taught for 8+ years at the start of the year. Finally got someone to take the risk of hiring someone who's "untested" and only done small and odd jobs professionally. This kickstarted my career, super grateful for that!
- Started my own programming consulting company.
- Gained enough confidence to apply to other jobs, snatched a few consulting jobs, nailed the interviews even though I never practiced any leet code.
- Currently work as a 99% remote dev (only meet up in person during the initialization of some projects.) I never thought working remotely could actually work this well. I am able to stay productive and actually focus on the work instead of living up to the 9-5 standard. If I want to go for a walk to think I can do that, I can be as social and asocial as I want. I like to sleep in and work during the night with a cup of tea in the dark and it's not an issue! I really like the freedom and I feel like I've never been more productive.
- Ended up with very happy customers and now got a steady amount of jobs rolling in and contracts are being extended.
- I learned a lot, specialized in graph databases, no more db modelling hell. Loving it!
- Got a job where I can use my favorite tools and actually create something from scratch which includes a lot of different fields. I am really happy I can use all my skills and learn new things along the way, like data analysis, databricks, hadoop, data ingesting, centralised auth like promerium and centralised logging.
- I also learned how important softskills are, I've learned to understand my clients needs and how to both communicate both as a developer and an entrepeneur.
Worst:
- First job had a manager which just gave me the specifications solo project and didn't check in or meet me for 8 weeks with vague specifications. Turns out the manager was super biased on how to write code and wanted to micromanage every aspect while still being totally absent. They got mad that I had used AJAX for requests as that was a "waste of time".
- I learned the harsh reality of working as a contractor in the US from a foreign country. Worked on an "indefinite" contract, suddenly got a 2 day notification to sum up my work (not related to my performance) after being there for 7+ months.
- I really don't like the current industry standard when it comes to developing websites (I mostly work in node.js), I like working with static websites (with static website generators like what the Svelte.js driver) and use a REST API for dynamic content. When working on the backend there's a library for everything and I've wasted so many hours this year to fix bugs and create workarounds related to dependencies. You need to dive into a rabbit hole for every tool and do something which may work or break something later. I've had so many issues with CICD and deployment to the cloud. There's a library for everything but there's so many that it's impossible to learn about the edge cases of everything. Doesn't help that everything is abstracted away, which works 90% of the time but I use 15 times the time to debug things when a bug appears. I work against a black box which may or may not have an up to date documentation and it's so complex that it will require you to yell incantations from the F#$K
era and sacrifice a goat for it to work properly.
- Learned that a lot of companies call their complex services "microservices". Ah yes, the microservice with 20 endpoints which all do completely unrelated tasks?

(I'm not completely sure of what I'm saying here, so don't take this too seriously)

Settling on a language to write the api for ranterix is hard.

I'm finding a lot of things about elixir to be insanely good for a stable api.

But I'm having a lot of gripes with the most important elixir web framework, phoenix.

Take a look at this piece of code from the phoenix docs:

defmodule Hello.Repo.Migrations.CreateUsers do
use Ecto.Migration
def change do
create table(:users) do
add :name, :string
add :email, :string add :bio, :string
add :number_of_pets, :integer
timestamps()
end
end
end

Jesus christ, I hate this shit.

Wtf are create, add and timestamps. Add is somehow valid inside the create, how the fuck is that considered good code? What happens if you call timestamps twice? It's all obscure "trust me, it works" code.

It appears to be written by a child.

js may have a million problems. But one thing I like about CJS (require) or ESM (import) is that there's nothing unexplained. You know where the fuck most things come from.

You default export an eatShit() function on one file and import it from another, and what do you get?
The goddamn actual eatShit function.

require is a function the same way toString is a function and it returns whatever the fuck you had exported in the target file.

Meanwhile some dynamic langs are like "oh, I'll just export only some lang construct that i expect you to specify and put that shit in fucking global of the importing file".

Js is about the fucking freedom. It won't decide for you what things will files export, you can export whatever the fuck you want, strings, functions, classes, objects or even nothing at all, thanks to module.exports object or export statement.

And in js, you can spy on anything external, for example with (...args) => debugger; fnToSpyOn(...args)

You can spoof console.log this way to see what the fuck is calling it (note: monkey patching for debugging = GOOD, for actual programming = DOGSHIT)

To be fair though, that is possible because of being a dynamic lang and elixir is kind of a hybrid typed lang, fair enough.

But here's where i drop the shit.

Phoenix takes it one step further by following the braindead ruby style of code and pretty DSLs.

I fucking hate DSLs, I fucking hate abstraction addiction.

Get this, we're not writing fucking poetry here. We're writing programs for machines for them to execute.

Machines are not humans with emotions or creativity, nor feel.

We need some level of abstraction to save time understanding source code, sure.

But there has to be a balance. Languages can be ergonomic for humans, but they also need to be ergonomic for algorithms and machines.

Some of the people that write "beautiful" "zen" code are the folks that think that everyone who doesn't push the pretty code agenda is a code elitist that doesn't want "normal" people to get into programming.

Programming is hard, man, there's no fucking way around it.

Sometimes operating system or even hardware details bleed into code.

DSLs are one easy way to make code really really easy to understand, but also make it really fucking hard to debug or to lose "programming meaning".

My first real programming teacher. She showed us strings, then made us use dynamic arrays in C++ for a year and a half. But we learned pointers and arrays very well!

The hard way can be the best way for education.

So, guys, I'm wondering if someone can help me wkth this thing. I'm sorta newish to programming and was searching up different kinds of typing. Basically what I found was:

Strong: Variables are explicitly declared, can only be changed to values of that type

Weak: Variables are implicitly typed, can accept any value of any type.

However, upon searching static and dynamic, it says the same things for dynamic and weak, and for static and strong. Can anyone help me by telling me the dofference between these (if you even understood this post 😅)

Thanks

Trees -> declarative programming

Loops -> functional programming

Sequences -> imperative programming

Graphs -> dynamic programming

Good mapping, yeah or no?

Happiness is finally using dynamic programming at work.

Anyone ever tried to fuck around with dynamic programming in machine learning?
My question is more towards rounding numbers.
Any papers on the impact of learning rate or precision that you guys know of?

Teacher : So today we'll study Dynamic programming.
In DP we solve the problem LCS.
Student : Ok one more algorithm atleast I'll improve my algorithms.
Teacher : (after 10 minutes) so this is how we make the table and find the solution. Now let's move to another topic
-- End of Dynamic Programming --

@algorithms_in_india

Any good programming language with great generics support that is not dynamic ?

Rust generics sucks so much I puked 2 times.

Tried with swift and it looks great.

Golang doesn’t have them.
Java sucks.

Maybe I try julia if someone say it’s cool.

I want to implement some 2d vector algebra and simple physics engine.

I started by creating generic 2d vector and trying to create dot product from it.

I didn’t wanted to do it in swift but wasted 2 days trying to do it in rust vs 1 hour in swift including 49 minutes of installing swift tools.

Anyway anyone know performant language with good generics support, let me know in comments.

Still as a scholar who has had his intership I decided that I was finally confident enough in my ability to apply for a small part-time programming job. I had an internship at a cool exhausting place with tons of expertise and I've proven myselve over there. So now I wanted a job on the side. Nothing special, just something that would make a little money with programming instead of washing dishes at the restaurant.

So I started at this small internet based startup (2 or 3 progammers) as a backend-oriented programmer. The working hours were amazingly compatible with my school schedule.

The lead dev also sounded like a smart guy. He had worked as a backend guy for years and had code running on verry critical public infrastructure that if it were to fail we'd be evacuated from our homes.

As a first asignment I got an isolated task to make an importer for some kind of file format that needed integration. So I asked for access to the code. I didn't get it since they were going to re-do the entire backend based on the code I wrote. I just needed to parse the file in a usable object structure. So I found out that the file format was horrible and made a quite nice set of objects that were nice. At the end of the first week or so I asked if I could get access to the code again, so I could integrate it. Answer was no. The lead dev would do that. I could however get access to my private repository.

Next week a new intern was taken to build a multiplatform responsive app. Only downside was that all the stuff he had ever done was php based websites. It wasn't going anywhere anytime soon, but I figured that that was where internships were for. So I ended up helping him a lot and taught him some concepts of OOP and S.O.L.I.D. and the occasional 30 minute rants of IndexOutOfRangeException, ArgumentException and such.

So one day he asked me how to parse a json string and retrieve a specific field out of it.
I gave him something like the following to start with:
"
JObject json;
if(!JObject.TryParse(jsonString, out json))
{
//handle error
}
string value;
if(!json.tryget("foo", out value).../// code continues
"

but then the main dev stepped in and proposed the following since it wouldn't crash on an API change:
"
dynamic json = new JObject(jsonString);
string value = json.myJsonValue;
"

After me trying to explain to him that this was a bad choise for about 15 minutes because of all kinds of reasons I just gave up. I was verry mad that this young boy was forced to use bad programming pracises while he was clearly still learning. I know I shouldn't pick up certain practises. But that boy didn't.

Almost everytime the main dev was at the office I had such a mindboggling experience.

After that I got a new assignment.
I had to write another xml file format parser.
Of course I couldn't have any access to our current code because... it was unnecesary. We were going to use my code as a total replacement for the backend again.
And for some reason classes generated from XSD weren't clear enough so after carefull research I literally wrapped xsd generated code in equivalent classes.

At that moment, I realized I made some code that was totally useless since it wasn't compatible with any form of their API or any of the other backend code. (I haven't seen their API. I didn't have access to the source.) And since I could've just pushed them generated XSD's that would've produced thesame datastructure I felt like I was a cheat. I also didn't like that I wasn't allowed to install even the most basic tooling. (git client or, Ide refactoring plugins, spelling checker etc...)

Now I was also told that I couldn't discuss issues with the new guy anymore since it was a waste of my valuable time, and they were afraid that I taught him wrong concepts.

This was the time that my first paycheck came in so I quitted my job.
I haven't seen any of the features that I've worked on. :)

I am not a very experienced developer, so naturally I don't know many fundamental things. My thinking around a lot of the necessary things is that the answer should come to me according to the need. So an oversimplified example could be, say I'm solving a Dynamic programming problem, I should not need to know the algorithm beforehand I can maybe invent it. This thinking stops me learning a lot things because I feel like then when I learn a pattern I will restrict my thought process within the knowledge I have and not think beyond it. I feel like that I am doing the dumb mistake of learning things bt heart and not understanding.
Does anyone felt the same? What your experience says about this?

Can anyone help me understand how can I identify Dynamic Programming problem and general framework to solve the problem using DP?

I am a beginner in programming. Started to code some 9 months back. So far I have learnt some basic C, Python(from LPTHW), HTML, CSS, JavaScript(from Coursera). I want to advance my skill. One of my relatives who is a programmer too advices me to learn SQL now and then learn PHP. So according to you what should I do now. I also want to develop my Python skills to using its frameworks so that I can make some real stuffs with that.

Pls suggest me my next move and also tell me from where can I learn these things( free courses could be of more help to me). I want to quickly learn the most of these so that I can make a dynamic website and web apps in the near future.

Thanks in advance!
