I agree, right now the home page is too specific about elm and types.

I'll admit react is not the ideal technology for frontend but it is also not a bad one especially given the alternatives of designing one's own ui library. It is in demand not because it's the best technology but because it&

Sorry but I really cannot understand how this is the case. In my short experience one can't make a significant impact to a mature large scale software product in 2 years. What kind of impact I'm talking, the kind of impact that

I personally deeply understand a new language only if I write the same code in two languages, one that I already know very well in your case c++ and the other I'm trying to learn, in your case that's rust. If i just learn from th

While this article doesn't do a good job of showing the benefits of state model, I still think it's a great way to build ui. Thinking of ui as derived state from your application model really helps in scaling ui applications relia

Elm is generally known to be a simpler Haskell. It's only useful for frontend apps right now but worth a try

I have found that the most important bit as a backend engineer is modelling the application domain precisely. A taste for making good APIs helps and knowing how to measure performance. These days most backend engineers also tend to manage d

Yes higher order functions. A function that takes a function as an argument or returns a function. In lisp you can think of a higher order function as taking data, processing it and then returning it just like any other normal function bec

Immutability doesn't mean you can't delete old records.

what kind of language are u using, using a statically typed functional language most removal of code is self obvious and even automated. u remove a method, it tells u to remove this and this too.

There's a problem here as the author himself notes. I can provide you a simple example of a function with monadic interface, you will understand it any language but that will not actually help you to conceptualize the idea of monads a

by aszen 5y ago
If you want to just get things done, and then learn the concepts of fp, I always suggest using elm. In elm I had been using andThen functions without even knowing they were related to monads.

by aszen 5y ago
Is that true though, you can't define a generic monadic interface yes but you can implement the same interface for your data types. That makes it less useful as the post says but still pretty powerful in some cases

The problem with this comment is that it fails to account for the fact that US and other democratic countries have a reasonable judicial system that while flawed is not totally under the thumb of the government. One can be sure that a death

It's important to note that Egypt is also run by an autocratic regime which is fearful of the influence of hamas and other revolutionary parties like Muslim brotherhood. I think Israel for all their supposed military intelligence is th

Some test cases are really important and cover the whole domain, take as example the tc39 tests, they are really all you need to fulfill to create a compliant javascript implementation.

by aszen 5y ago
Yes ofcourse. Having tests helps a lot, take as example someone building a markdown parser. If u have the knowledge of how to build parsers, then an existing suite of tests is going to speed your work quite a bit by ensuring that you build

I think immutability isn't really a feature with use cases. It's a way of programming without modifying data structures in place/in memory. It's also enables us to retain old values by generating new ones without modifyi

I'll try to justify, imagine you have working code with no tests, it's been running for years but no one can understand it or change any of it. It's providing a very fixed value. Now imagine you have all the tests laying out

by aszen 5y ago
If you are trying to put structure to your code, you would like to get instant feedback on how that structure works from the outside. That is how the api works, the best way to do is to make a test which actually uses your code, and asserts

If u are looking at this from a profitable angle then getting ux right is about gaining more users and making them pay. Technical innovation is about creating something which wasn't possible before and not making a start-up wrapper ove

When people say docker helps in making dev look like prod, I assume they are running everything on docker in production, but that is very rarely the case with dbs, queues and cloud specific services. Interesting I'll check this script,

This may change in the future with Nix moving to a content addressable store. I lack the technical know how behind it, but if the output of a package doesn't change on changing one of the inputs then nix will not rebuild it's cach

Docker truthfully told is unusable for Dev envs that need to change constantly. It was never built to handle this use case. I haven't seen a good docker compose file that can be reliably used as a development environment in multiple os
