Another List-Related Asymmetry — A long time ago, I wrote an article about The Asymmetry of ++, thanks to Fede Bergero’s findings. Let’s add a few more asymmetries to that list… Note: This article is based on OTP23. Many things have been improved since that version already. Introduction Initially, I thought about writing this article…

“Memory management is like taking out the trash — it’s not glamorous, but it’s necessary for a clean and efficient system.” — Hi folks! Ukrainian Erlanger is here 🤘! In the current topic, I want to describe a little bit more the Erlang Garbage Collector. Many developers lose sight of it or just don't understand it. That’s because either they lack the time to research it or interest in this topic —…

Mi Reseña — Luego de casi quince años de trabajar, enseñar y difundir Erlang por el mundo, recién hace unos pocos días tuve la posibilidad de leer mi primer libro sobre Erlang en castellano. Se trata del libro que da título a este artículo y está escrito por Manuel Rubio. …

"Time and space are not conditions of existence, time and space is a model for thinking." — Albert Einstein. — Hi folks! Ukrainian Erlanger is here 🤘! We continue our series of articles about Erlang/OTP profiling. In this article, I want to talk about eprof: an old but still pretty useful tool for analyzing the time spent by our Erlang programs. …

“Time and space are modes by which we think and not conditions in which we live.” — Albert Einstein. — Hi folks! Ukrainian Erlanger is here 🤘! In this new series of articles, I want to talk about Erlang/OTP profiling. In this article, in particular, I want to draw attention to fprof — a fantastic tool to profile programs to figure out where they spend their time. …

"Many programs don't have a well-defined interface. They should have." — Joe Armstrong. — Hi folks! Ukrainian Erlanger is here 🤘! In this article, I want to talk about Erlang and ASN.1 — specifically about ASN.1 in Erlang. The purpose of this article is not to teach ASN.1 but to show the capabilities and interaction between Erlang/OTP with ASN.1. However, in the article, you…

"In real open source, you have the right to control your own destiny." — Linus Torvalds. — Hi folks! Ukrainian Erlanger is here 🤘! In this article, I want to talk about contributions to Erlang open-source code. And no — I'm not talking about some Erlang project — I'm talking about contributions that go directly into Erlang/OTP itself. Perhaps it is worth noting at this point that I…

“We become what we behold. We shape our tools, and thereafter our tools shape us.” — Marshall McLuhan. — This article is about rebar3_plugin — a simple GitHub template repository for quickly building your own rebar3 plugins. We created this one together with Brujo Benavides just for you! 🥰 In the article “Spell check your Erlang code with Sheldon” I quickly mentioned this tool — but since all should…

“Scissors cuts paper. Paper covers rock. Rock crushes lizard.” — In the article “Sheldon: Erlang spell checker”, I described the fantastic library Sheldon and how it can be used for spell checking stuff. Today, we will discuss the Erlang plugin rebar3_sheldon that uses Sheldon to spell check Erlang source code. …
