Curiosum TILs

So, you’re changing this one file for local development purposes only. Maybe it’s config, maybe some source file, but one thing is certain - you don’t want those changes to be committed. And what’s worse, .gitignore doesn’t work.

In the world of Elixir programming, there are numerous features and syntactic constructs that contribute to the language's elegance and expressiveness. One such hidden gem is the concept of "implicit try".

Today's Advent of Code puzzle inspired me to create this TIL. It may sound trivial, but in fact, it's tricky if you are unfamiliar with the nuances of guards' functioning.

It's easy to contain absolute positioned elements. Things get a little trickier when you want to contain a fixed positioned element without changing its stylings.

Warnings in Elixir are usually an important sign of a problem in the codebase. There is an easy way to make them gone.

Each of us had a situation, where we had to invoke a few, same commands each time. Making it once is not that problematic, but when we are supposed to repeat given operations, it may be better just to create one function that will handle it all.

Pattern-matching is one of the finest elixir-lang features. Whoever knows the power of this tool once, will want to use it forever.

Did you ever create a commit that you wish never happened? Let's be honest - we all did. There is an easy way to revert it in Git.

TLDR: With jest-extended package you can write: expect([...set]).toIncludeSameMembers([value1, value2]);. If you are looking to a native, but longer solution scroll down a bit.

Sometimes we want to store some piece of information while using a terminal, for example, a result of an executed command. We usually save it into some temporary file which is going to be deleted after all. There’s a better way.

If you ever had to count occurrences of values in Elixir's list, this short post might be helpful for you!

There are a bunch of operations you may want to perform before the rendered response in conn is sent to the client, such as minification. In this post I'll show you how to do it easily.
