My senior: Congrats on finishing up the basics
Me: Those were just basics???...///!!! 😜

Definitely Rust, and a bit Haskell.

Rust has made me much more conscious of data ownership through a program, to the point that any C/C++ function I wrote that takes a pointer nowadays gets a comment on ownership.

I wish it was a bit less pedantic about generics sometimes, which is why I've started working on a "less pedantic rust", where generics are done through multiple dispatch à la Julia, but still monomorphising everything I can. I've only started this week, but I already have a tokenizer and most of the type inference system (an SLD tree) ready. Next up is the borrow checker and parsing the tokenized input to whatever the type inference and borrow checker need to work with, and of course actual code generation...

Haskell is my first FP language, and introduced me to some FP patterns which, turns out, are super useful even with less FP languages.

The more I use Go, the more i start to like it. I didn’t realize how nice being able to generate binaries for every OS that matters was, until I had that power. It beats the hell out of trying to distribute a Python app for sure.

Sure, it has its warts.

It’s overly bureaucratic in the same way Java is.

I hate that you can’t import something without using it (most people I’d wager preemptively import libraries they know they’re gonna need even if the code isn’t written yet)

I really wish there was a way to just say “See this JSON blob? All those keys and values are strings, trust me, you don’t need me to tell you the type of each one individually.”

Generics would be nice.

I’d kill for exceptions - any decently sized go program is going to have very many if err checks where most could be condensed down to a single try/catch in most other langs.

I wish the tooling was better. Dependency management was a solved problem when Go was released and yet they chose to ship without it. There’s still no standard. Many hours of time have been wasted dinking with this.

But ya know what? Even with those warts, it’s still easier to write than Java. It’s still write once run anywhere, it’s blazing fast, and doesn’t require your end user to install an entire freakin runtime.

I've been using microsoft dev stack for as long as i remember. Since I picked up C#/.NET in 2002 I haven't looked back. I got spoiled by things like type safety, generics, LINQ and its functional twist on C#, await/async, and Visual Studio, the best IDE one could ask for.

Over the past few years though, I've seen the rise of many competing open source stacks that get many things right, e.g. command line tooling, package management, CI, CD, containerization, and Linux friendliness. In general many of those frameworks are more Mac friendly than Windows. Microsoft started sobering up to this fact and started open sourcing its frameworks and tools, and generally being more Mac/Linux friendly, but I think that, first, it's a bit too late, and second, it's not mature yet; not even comparable to what you get on VS + Windows.

More recently I switched jobs and I'm mainly using Mac, Python, and some Java. I've also used node in a couple of small projects. My feeling: even though I may be resisting change, I genuinely feel that C# is a better designed language than Java, and I feel that static type languages are far superior to dynamic ones, especially on large projects with large number of developers. I get that dynamic languages gives you a productivity boost, and they make you feel liberated, but most of the time I feel that this productivity is lost when you have to compensate for type safety with more unit tests that would not be necessary in a static type language, also you tend to get subtle bugs that are only manifested at runtime.

So I'm really torn: enjoy world class development platform and language, but sacrifice large ecosystem of open source tools and practices that get the devops culture; or be content with less polished frameworks/languages but much larger community that gets how apps should be built, deployed, monitored, etc.

Damn you Microsoft for coming late to the open source party.

The new mobile app codebase i'm working with, was clearly written by someone who just read a book on generics and encapsulation.

I need to pull out 2 screens into a separate library to have it shared around. The 1 networking request used is wrapped up in a 'WebServiceFactory' and `WebServiceObjectMapper`, used by a `NetworkingManager` which exposes a generic `request` method taking in a `TopLevelResponse` type (Which has imported every model) which uses a factory method to get the real response type.

This is needed by the `Router` which takes a generic `Action` which they've subclassed for each and every use case needing server communication.

Then the networking request function is part of a chain of 4 near identical functions spread across 4 different files, each one doing a tiny bit more than the last and casting everything to a new god damn protocol, because fuck concrete types.

Its not even used in that many places, theres like 6 networking calls. Why are people so god damn fucking stupid and insist on over engineering the shit out of their apps. I'm fed the fuck up with these useless skidmarks.

this month the lead dev was not in and I had to make a new feature. Guess what I did :)

tdd [coverage >90%], a couple of builders, a factory or two, two composites, one decorator, only a few generics - only where really needed. Private fields, not a single @Autowired field [they were fucking my tdd], nicely abstracted integrations, and so on. Everything is writen according to clean code: max 10loc methods, <140col lines, reusable constants and utils, SOLID as a rock, etc.

Due date is next week. Took me 3 weeks to craft it.

Guess who's gonna be piiiiiiiiiiiiisssedd 😁

the best part - I don't even work there, our company was hired for xx hours as helping hands 😁

that's not all. They have like 6 envs and their deployment is all-fucking-manual. Will try to learn how to dockerize that app and deploy it on docker. Gosh I wish I could see his face when he's back 😁

p.S. From ethical point of view, he's the only dev who believes his code is perfect. No other dev in the team agrees. AND he once said: 'it's gonna be my way or no way at all'. So I don't think I did wrong... Did I? :)

So c# has its own system.collections.list and system.collections.generics.list<type> classes. And this guy wrote his own list (no generics) using an object[] array which always had same size.

The efficiency of every dev stack in the world will never compare to just dropping my folder of php code into a server, with proper configurations, routes envs and everything else into a folder and watch it run.

I a pops shop wants me to build something for them? php

If an enterprise grade with a lot of users comes about? php

I have yet to have a single issue with it as most of you evee poluted, herd ready, mob mentality mfkers want to make believe.

Legit, the language is flawed, but has yet to fuck with me, i have memorized the quirks and fuckups of the language (much like I have done with JS) to know that a lot of you just bandwaggon over shit.

"It DoeSnt hAve proPer geNerics"

boom, deployed a form to a customer for his site, charged $2k for a one day job with no issue. But go ahead, setup an entire fucking pipeline of dependencies, a .net app and/or an entire bs app in node or rails(which I love btw) or an entire fuckState centric app in Go that gets messier the more you look at it and it would not be as easy or as simple to deploy.

Legit, in my entire career, nothing makes my life simpler for the web.

Constructors, generics, collections, package versioning, immutability, syntactic sugar, option types? Meh.

Unused imports? NEVER!

#golang

I bring you all another gem from my computer science course, this time from my OOP class.

The first assignment we made for this class was a simple CLI shop, where you would have basically three main classes:

- A Product class that you extend to create different types of products.
- A Cart class that manages a list of products (basically an ArrayList<Product>) and has some useful methods
- A CLI class to display a simple interface to the user and call methods on a Cart.

Basic OOP stuff, so far so good.

Then for our second assignment the teacher asked us to make Cart a generic class, where you would say Cart<Bagel> and you would only be able to put bagels in it. This makes absolutely no fucking sense, this is not a good use case for generic types since

1) you would never limit your customer's cart to one type of product at compile time.
2) in Cart, you have to cast the generic type to Product to extract any information from the product, like when getting product prices to calculate the total price, so might as well use a fucking ArrayList<Product>

I'm just saying what he's asking us to do has (to our fictional shop's business logic) absolutely no advantage over subtyping.

Also, why the fuck teach generic constraints when you can just tell your students "just cast T to Product", right?

Like fucking hell, couldn't you spend like 10min to come up with a decent assignment that actually teaches generic types the right way? ffs

And just so no one can say "but wut simple assignment would you give to teach students generic types?", here's a simple and much, much better alternative: implementing your own ArrayList. Done. Can't get much better than that, it's a legit use case and teaches you the basics.

Sorry man, you're a great person, you really are, but you suck as a teacher.

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!

Making a generic class for event management

Welcome to the par<T>

Everyone's saying "oh my, I'm so ashamed of my code I wrote 4 days ago, it's so horrible"

Well... At least you can relate to someone. When I look at my project's code I wrote half a year ago (or sometime before that) I'm genuinely surprised to see I'm not browsing some library's codebase - the abstraction layers, the generics, the structure... it's brilliant! It's as SOLID as it gets.

Stop. Using. Fucking. ADA. To. Teach. Basic. Programming.

I wouldn't say you should use a dynamically typed language like Python, but having programed since high school, I hated each and every aspect of Ada. We were even taught OOP and generics with it! (And not, you do not want to know how it is, because it is dreadful)

I'm boutta make a scripting language with classes, trait generics AND two kinds of value types

Call me Mr. Dangerous 😎

That moment when you automated the application so much, working on it get's actually kinda boring 🙈😂

Worst documentation? Unreal Engine 4's documentation on editor customization (custom panels/windows and whatnot). It might have improved in the last two years, but the last time I made a custom editor there was almost zero documentation on the matter and on their Slate UI framework. The little documentation that existed was very vague and had awful examples.

I don't remember very well, but I think it took me close to two weeks to get something very basic working. I had to read a LOT of C++ code filled with generics and macros to figure everything out, but after I did I enjoyed a lot working with that stuff.

I just don't know how I was able to do that, working with UE4 was a pain the butt every. single. day. Runtime error on the gameplay code? Too bad, the whole editor will crash and then take ~40s to reopen. It was crash after crash, ~1min of compilation time for any little change to the code, so so so so much frustration.

I do miss a those times a bit though, because even though it was hard, it felt good to feel competent, to know something complex reasonably well to the point I could help people on forums. Today I always feel I don't know enough about the languages/frameworks I use. It's kinda depressing, it takes a huge toll on my self confidence. But whatever, let's keep going, one day I'll get there :)

Dear php. You weren't my first one. But you were my first serious one. The first i made money with. We had a great time together until ajax came. Do you remember? I did more and more with js later but you still where my main. You even exposed your source code to me. Time changed. They started to hate you. And yes, they where right in some points. But they never saw your good sides. I saw them. I stood with you. But i was froced to wrote backends in typescript, in Java. And you know what: i didn't feel so bad. For gods sake, I fucking enjoyed it, php!

When did we become so alienated? When did I staet to write my dayly heller scripts in bash instead of you?

Yes, you improved. Hack came, than php7, php8. You archived a lot. You finally brought types. There was a time when I thought everything that stood between us will be overcome. That we will be together forever.

But recently i had this conversation on DevRant with nmeri and did some research afterwards. And I learned, maybe you will never have generics. It just don't work out, php, I am sorry. It's not your fault, it's mine. But i dont think i can live without a proper type system for the rest of my life. Not after i taszed those other languages.
I don't know when it will happen. When i switch projects this summer maybe. Maybe next year, when i start a new job. Who knows. But it will happen: you won't be my main anymore at one point. Maybe we can stay friends but i want you to know, that i am open for something new in my life. Something with generics.

Well this is the thing. I have been starting to replace a lot of my shit with Golang. I think it is a great language because of one small fact: it is a boring language.

With this I don't mean that it is not incredibly fun to use. It is and honestly I feel that a lot of the concepts that I had from C passed quite nicely with some additions. The language does not do anything special and there is no elegant code. It works in a very procedural fashion without taking into consideration any of the snazzy things found in JS, Python, c# etc etc. Interfaces and struct make sense to me, way more than oop does in other languages. I don't need generics with the use of interface parameters and I have hadly found a situation in which I have to strive too far away from the way things are done with Go to be happy with it, then again my projects are not hard or by any means groundbreaking (most of them deal with logistics or content management and a couple of financial apps that I am rewriting in Go from work)

The outcome is fast and easy to read since idiomatic go is for the most part very readable(no people...single letter variable names are by no means a standard and they should feel ashamed from it)

I miss the idea of a framework, but not so much and the docs and internal code for Go is just way top inviting. I believe the code to be readable enough than anyone that has gotten used to the syntax and ideas of the language can just jump in and start learning. This is the first language that I have learnt from studying the code as it is inside of the standard lib, the same I cannot say for any other language or framework.

Also, it play beautifully nice with vs code.

I dunno man, I feel that I am doing something wrong. I have projects built in Node, php, python, ruby and spring java as well as .net core and I still find Golang way more appealing simply because it goes harder than Python with "one preferred way" to do things.

The lang does not make me feel like a pro, i certainly develop in it at pro speeds, but it was made with beginners in mind to built fast and concurrent apps, with the most minimal syntax possible.

I guess my gripe with it is that it gets shunned from this, saying that it ignored years of lang research to make it as dumbed down as possible. Which it did, lack of generics amongst other things certainly make it seem like, but I will not say that it was poorly designed. Not at all, I believe it is a testament of amazing engineering. To be able to create such a simple yet amazingly powerful language.

Wish there were more to it. Wish there was a nice gui lib or a ml framework comparable to the ones offered by python and java. But I guess such things will come with time.

I feel stupid with this language.

And that is fine.

Any other language: Hey fuckface, you can't name this variable by a single letter, tf is wrong with you? use some descriptive shit.

Golang: lmao fuck u

I really find it interesting how we use short variable names for items in golang. Kinda makes sense when you think of it. Most of these items come up in short methods for which the mental model lets you know and remember what you are doing, they even make sense when going through the std lib in which that shit is all over the place. YET years of going by other languages has made me squint my eyes a bit in frustration every time I see it.
Say for example that a function is implementing io.Writer. What would you call the method parameter? you could argue that writer would be sensible since it has it in the signature, but what about when the io.Writer in itself is a file or a socket or whatever? writer would be funny or strange? nah fuck it just w, it makes sense, but x wouldn't. I find these points to make sense even if i don't like them.

Would, now, this practice be acceptable in C? you are supposed to write the same modular code with C in which you compose large functionality in separated units of code, yet I am sure this practice of single name variables is something that C engineers dislike greatly.

Are go devs just doing this out of blind love for their preference in languages? and how would this work if mfkers add generics to go(I hope not, Go is simple enough to understand in order to extend functionality through the empty interface, but that is a preference of mine as well)

The more I use Go the more I like it to be honest, I think the code looks ugly syntactically, but that is subjective as all hell and based on my constant preference for a language to look like Ruby, which even though it might not be everyone's cup of tea it remains to my eyes as the most beautiful language in existence, again, an obvious personal preference.

If you just stay calm and focus on building, you'll eventually come across things you've always wanted to learn, but didn't really see the purpose of it, this applied to everything in life.

For example, today was the first time I needed to use generics in my app, this is something I've always wanted to learn but didn't truly understand it. I've read docs and watched videos online, but still didn't see the benefit of learning generics.

However, once I needed it, I realized why it is relevant, and thus created stronger memory muscles.

Let's break this down:
- You learn more if the thing you need has a purpose.

- Information is simply data, once you apply it, information turns to knowledge.

And this my fellow dev friends is what you get paid for, not information, but knowledge.

And what is knowledge? - experience.

!rant

I've been working with Golang for a while now and I've come to love the generics they introduced. Making stuff type-safe is a bit of a hassle, but it pays off greatly.

One thing I had yet to consider though, is that functions are also a type, so that those could be made generic too.

func DoThing[F func(string) | func(int)](callback F) {...}

Now you can deliver both function types and I can differentiate them using a type switch.

Weird that sometimes my brain doesn't make that connection immediately...

Started porting one application written in php to:
Golang(and some libraries to make certain sht simpler like GORM and Gorilla amongst a couple of others, most shit is STD shit already built in)

Java Spring(I know it well, but wanted to try this particular app in it, lots of boilerplate although the coded is solid AF)

.NET Core API, which I separated in a series of modules for the domain interface, the persistence logic, the actual api etc, I really dig it. It has a basic React frontend in Typescript whereas the other 2 versions are using the standard Go html/template package and the Twig interface for Spring.

My favorite thus far is Golang. I find it extremely easy to extend, the language reads good enough for a retard like myself to make sense of it fairly easy, really easy to test and experiment with it, any idea I get for something to add(say users and stuff) took me less than 30 mins to figure out while reading the actual documentation, as in the base documentation or just the source code.

I know the language is retard proof, and I am highly enjoying this. Not to say that the other two are bad, not at all, been using C# and Java for years now, but I highly appreciate being able to concentrate on functionality rather than all the fucking architectural boilerplate needed to run basic shit in the other two frameworks. Thus far Golang has been a breath of fresh air the likes Clojure gives me, while not even being a profound or mind blowing language in terms of features(since other than the interface{} and goroutines i can't think of shit) and have not reached a scenario in which I am stuck or dying to have generics one bit for the overall business logic.

The app is growing like crazy in terms of code since the original php application was huge to begin with, but dear me this shit is as simple as it can get without being too technical. Might move it to production once all usability tests pass and force the rest of the staff to learn it. I have one lead dev that damn near refuses to touch anything other than php, and a very eager to try shit out content administrator that comes from a Java and C# background.

all I want to say is how much I love go haha

I don't know what to do because union and sum types both totally suck but I need them for my scripting language

Union types are fun and intuitive because they can be used with type refinement but they're not hierarchical thus bad for generics.

Sum types (or tagged unions) are great because they're hierarchical and can be nested properly but they need ugly type matching constructs.

The positive thing is I'm not making a systems language anymore so I only wanna jump of a bridge every second day

I've ranted about this before, but here we go again:

Go Plugins.

I was racking my brains trying to figure out how one could possibly implement plugins easily in Go.

I had a look at using RPC, which requires far to much boilerplate to be realistic. I looked at using Lua, but there doesn't seem to be a straight forward way of using it. I was even about to go with using WASM (yes, WASM). But then I came across Yaegi ("Yet another elegant Go interpreter", you heard right: "interpreter"), Yaegi is also very easy to use.

There are a few issues (including some I haven't solved yet), including flexibility (multiple types of plugins), module support, etc. Fortunately, Traefik just released their plugin system which is based on Yaegi (same company), and I got to learn a few tricks from them.

Here's how module loading works: The developer vendors their dependencies and pushes them to a repo. The user downloads the repo as a zip and saves it to the plugins folder. I hash the zip, unzip it to a cache, and set the the GOPATH for the interpreter to be that extracted folder. I then load the module (which is defined by a config file in the folder), and save it for later. This is the relatively easy part.

The hard part is allowing for different types of plugins. It looks easy, but Go has a strict typing system, makes things complicated. I'm in the process of solving this problem, and so far it should go like this: Check that the plugin fits an arbitrary interface, and if it does, we're good the go. I will just have to apply the returned plugin to that interface. I don't like this method for a few reasons, but hopefully with generics it will become a bit more clean.

I am overwhelmed in my mind right now and I kinda just need it out.

I'm incredibly divided. There's so much I want to do which is fine I can balance some of it kinda well but when it comes to the programming aspects of what I want to do is where my head gets tugged in multiple directions.

Parts of me really want to continue to dive into C# and learn it a lot more than I currently do so I can continue to write the tools I use for problems I come across.

And the other part of me just wants to go do lower level development with C because that's where most of my goals are being mostly embedded and OS development.

But so many people I know that are incredibly smart devs use C# and I see why it's an incredible language and I'm glad it's one of the languages I know but I feel like there's so much to learn about it and I there's so much shit I see that I'm just like I don't know when I would want to use this, or I can see X feature being very useful but I don't know where I'd use it in my projects. Hell even C#s version of structs I know are very useful but I'm not able to make good use of them

I'm just in that headspace where I'm not learning enough and I feel dumb when I look at someone else's project because there's a lot more complexity In their project that none of my projects have ever had and so many people make use of language features I've never used or thought about using (generics being a good example) and I'm constantly asking questions which I know is okay but too much is happening in life lately and it's just making it harder to handle.

Thanks to anyone that got through it hopefully I'm not alone in these feelings

[LANGUAGE DESIGN]

What are some interesting / unique approaches you've seen to representing generics in syntax? The only one I know is the Java/C#/Typescript way of using a separate set of parentheses and either specifying all of them or none, and I've already experimented a bit with passing them as regular arguments which works great with autocurry but every syntax option for inference adds visual noise.

Did you know Swift can't handle generics over protocols (interfaces)? Me either until just now. 😣

Why Android uses so many quirky features in Java, like inner and anonymous classes, callbacks and nested generics?

I searched everywhere for the reason but can't find why, only how.

I rarely use these features outside of Android development.

Thoughts on Flutter!
I'd like to see something like flutter for front end web development. I like the approach used by Google for Hybrid app development.
Dart language fits perfect for the case. Static typing, OOPS, Generics, state management, UI design everything right out of the box.
I don't have to create layout separately like HTML in web or XML in android.
Everything is managed by Dart alone.
It's like what developer wishes for UI rich app development.
I'm not saying Flutter or/and Dart is the perfect solution. Every language has pros and cons. (Maybe not applicable to JavaScript! Haha! ) But still The overall solution to UI development is way cleaner than web.

I go to add a method call in a business logic class that's used exclusively in a particular service, and get blocked in the PR by some other guy-

Other Guy: refactor this into the shared framework referenced by all our microservices

Me: it is only and would only be used in this service

OG: what about the other business logic class in this service?

Me: it's not used there, and if it does end up used there then we can refactor it into a class that they both reference then

OG: I need to know when the abstraction of this function will be done. is it going to be delivered next sprint?

Me: YAGNI - better to avoid doing extra work when we don't know if we'll even need it

OG: tbh you can still abstract it with some generics and lambda magic, but im not gonna enforce that

Me: premature abstraction is the root of all evil (tongueout)

OG: not really, its the root of not having a million miles of tech debt in 2 years

I just can't win for losing with the anti-YAGNI yogi.

Golang has to add generics in version 2.

Generics look kinda cool. But it doesn't takes long before it becomes a giant mess. And then a manager asks for some new functionality and you end up changing every class that inherits from it. I hate and love it at the same time. A confusing relationship.

I have very mixed feelings about Go's KISS policy. They did manage to keep a lot of stuff easy and they force dev's to not over complicate their code. But there is a line. Generics aren't that hard to grasp. I get focusing on *fearless concurrency*, but how about *fearless list processing* FFS

I have lost track of the whys, but I'm writing something that loads a datastructure not unlike specifications of C types (plus struct single inheritance and generics) from any DLL-s tossed in the same folder, then organizes them into a pretty database. Now I just gotta keep gradually broadening the scope until I get to the feature set of the modern C# type system.

Listening to a colleague starting to explain generics to the intern, then disappearing away from the area as fast as humanly possible so you don't loose a day!

TILb
C++ Templates are generics on steroids.
I'm kinda dying

Why the hell doesn't Go have generics?? You have to teach Go how to access elements of a list n times if you have n things that need to be sorted!

Hey guys,

I´m trying to create a generic class, which inherits from an Interface, which is also an generic.

My problem is to instantiate the interface with the correct type, cause the new class should use all classes from the instantiated interface.

Is this possible? It´s a bit complex ^^ but that´s just my thought :)

I have become very fond of React, but the pushback I've experienced when suggesting typescript is crazy.
I think this is the reason why so many enterprise apps are written in Angular. Type safety isn’t a crutch, it's a tool. Plus, interfaces are a dev time construct, and will not bloat the codebase since it doesn’t transpile into js.
But Ts also gives us a lot of other goodies that allow for cleaner design patterns and a better adoption of oop principals.
Also, generics/constructor types, whatever you wanna call it, are your friends. An Array<SomeEntity> or SomeEntity[] will give you peace of mind I’m so many scenarios.
Anyway, I have bitched enough.
Rant over.
Have a wonderful Christmas, everyone.
Ps. This isn’t aimed at anyone in particular, but a the react community as a collective. :)

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.

With C++11, fell in love with std::enable_if and others in type_traits.

Lets you take generic programming to a whole new level. I never used it when this was part of boost thinking it didn't make as much sense. Now, I like to qualify my template definitions to be as restrictive as possible based on the expected usage.

I guess these days I work with Golang, gRPC, and Kubernetes. I guess that's a dev stack. Or turning into one at the very least. The only thing that annoys me about this stack, is how different deployments for kubernetes are different for CSPs. The fact that setting up a kubernetes/Golang dev environment is take a lot of time and effort. And gRPC can be a pain in the ass to work with as well. Since it's fairly new in large scale enterprise use, finding best practices can be pretty hard, and everything is "feet in the fire" and "trial by error" when dealing with gRPC.

And Golang channels can get very hairy and complicated really really fast. As well as the context package in Golang. And Golang drama with package managers. I wish they would just settle on GoDeps or vgo and call it a day.

And for the love of God, ADD FUCKING GENERICS! Go code can be needlessly long and wordy. The alternative "struct function members" can be pretty clunky at times.

when prototyping generics just seem evil...

I could, but I should not.

Java: creating arrays of a generic type.

Doable but hacky.

SO TIRED of the typescript generics system. I get why you can't assign Thing<Foo> to Thing<any>, I do. But also, WHAT THE FUCK!? This is such a giant waste of time having to fix everything to pass around generics that I don't care about.

I've probably spent ~500 hours of my life wrestling this stupid ass type system.

java.util.Optional.or, orElse and orElseGet should really have their signatures changed so they can widen the type. For example, `Optional<T> or​(Supplier<? extends Optional<? extends T>> supplier)` should really be `<U, S super T & U> Optional<S> or​(Supplier<? extends Optional<? extends U>> supplier)`

Then we could eliminate the following unchecked cast:
```
public static double getOrNan(Optional<? extends Number> optionalNumber) {
return ((Optional<Number>)optional).getOrElse(Double.NaN).doubleValue();
}
```

Java introduced generics in version 5 which was a game changer, but what has it done since then? Is there anything in 6 - 8 that isn't just syntactic sugar?

Having the compiler crash whenever you start using generics.

Sooo. That starts to be a bit annoying:

I'm working on a large refactoring with a pretty good inheritance / generic system. And some code generators.

Rghjt now I'm doing a script which generate code files, which will generate code-gen templates which will generate final files.

It's funny and it's a one shot generation, but still. So much abstraction.

(End result is good tho. Everything in small files less than 15 lignes of code. Everything structured.)

In type systems without variadic generics, tuples should be defined as a type-level conslist:

Tuple<int, Tuple<string, Tuple<bool, TupleEnd>>>

Consider the possibilities, even just in a regular type system, then consider how much more is possible with dependent types!
