I expect to find out something informative from the title of the post like what I am going to learn or what kind of problem will be solved. Even if it’s a list of small tips some kind of hint would make a difference for me.


#215

Thanks. That really makes sense. I will take your point seriously and will come up with good concepts.
Once again thanks for the valuable feedback :bouquet: :bouquet:


#216

Hey all,

I’ve been honing my Elixir/Phoenix skills lately through what I’m calling “practical code katas”. I’m basically taking the idea of a code kata, and applying it to more practical and useful “forms” for professional, working web developers.

Check out the article and let me know what you think about this kind of thing.

I know a lot of developers see it as a waste of time, but I find the repetition to be really valuable and an efficient way of sharpening and fine-tuning every aspect of my process.

Why Erlang is the only true computer language
So far the only language I know that reports errors in the same language you write code is Erlang. If you know more, please let me know in the comment section below.

#221

I’ve been working on a side project that requires I do some web crawling. I decided to write an article (complete with cheesy drawings) outlining everything I’ve learned about using Elixir to build a very bare bones web crawler. Check it out!

Oh, I love your illustrations! Every technical blog post should have them!

#224

This is an interesting learning exercise. But to me, User Authentication is very boring, orthogonal to the inner workings of the rest of the app, and not something I want to waste much effort on. The fact that this blog post is a thing convinces me that we need a ready-to-use solution for Phoenix (more configurable than Coherence).

EDIT: Actually, user authentication is not that bad, but user registration, with the “traditional” email + password + email confirmation + password reset is that bad


#225

I’ve just published a blogpost on a simple getting stated version of keeping a history of a ecto schema’s field like for example the status of an entity:

The spans now show that we’ve eliminated the stair case and gone for the superior elevator scheme.

Lol!


#228

Yo!

I’ve got an especially nerdy article this time around.

I’ve been re-reading The Little Schemer again (which is amazing - check out the link in the post if you haven’t read it), and I managed to finally wrap my head around the Y combinator. I wrote an article that uses anonymous functions in Elixir to show what the Y combinator is, why it’s interesting, and how it can be derived.

Check it out: Grokking the Y Combinator with Elixir

Hopefully some of you are as into this kind of thing as I am, and hopefully the article makes this very mind-bending topic (for me, at least) somewhat clear.


#229

Hehe, I love the Y combinator, there are even legit uses for it in Elixir (like building anonymous functions that are required to close around their scope to make recursive closures) and there are people that have made the Y Combinator in libraries (like expede’s libraries). This is a very good article, approaching it from a different way than the usual way that I see it introduced. :slight_smile:


#230

Has Elixir got named funs yet, or are they planned? One major use of the Y combinator disappeared in Erlang when we got named funs, doing recursive funs. Though they could be done other ways as well.

But the Y-combinator definitely is cool.


#231

As in named (not just bound to a variable) lambdas? Interesting… Is the main use case of that recursion in (not-so-)anonymous functions?

I agree that the Y combinator is cool. I guess I was more so trying to show what an interesting construction it was, rather than give some practical advice. Some things just deserve to be marveled at.


#232

The Y-combinator really is cool but it is not how I would normally do recursive funs, at not before named funs. I would just add an extra argument which is a reference to the fun itself and use that for the recursive call.


#233

Not that I’ve seen at least?
