OTP 22 Highlights - Erlang/OTP
OTP 22 has just been released. It has been a long process with three release candidates before the final release. We decided this year to try to get one month more testing of the major release and I think that the extra time has paid off. We’ve received many bug reports from the community about large and small bugs that our internal tests did not find. This blog post will describe some highlights

A Comparison between Rust and Erlang
Erlang: The beauty of Erlang code conciseness comes from its pattern matching capabilities, which are available everywhere — on function names, number of parameters and parameters themselves, when using case statements, and when using the = symbol. Rust: In a let binding, the = symbol can be used for binding as well as for pattern matching. Apart from this, Rust match is similar to the case statem

Erlang/OTP 20.0 is released
Erlang/OTP 20.0 is a new major release with new features, quite a few (characteristics) improvements, as well as a few incompatibilities. There are only minor changes compared to the second release candidate, some of them listed below: ERTS: * erlang:term_to_binary/1 changed the encoding of all atoms from ATOM_EXT to ATOM_UTF8_EXT and SMALL_ATOM_UTF8_EXT. This is now changed so that only atoms act
TCP incast: What is it? How can it affect Erlang applications? | Humans and Hippos in Harmony
So, what’s the deal with the “TCP incast” pattern? Never heard of it? Join the club. I’ve been wearing a developer hat for too long and not wearing my sysadmin and network manager hats. And the publications about Ethernet microbursts and the TCP incast pattern have been hiding in conference proceedings & journals that I don’t follow. (Note to self: change reading habits.) If you’d rather read
Special Processes in OTP
On a recent Elixir project, I needed to test some asynchronous behaviour. Doing so led me to learn about the basics of special processes in OTP. Our project was using Phoenix Channels and had a need to keep track of all connected socket processes. We could have used the upcoming Phoenix presence feature, but we didn’t quite need all of its features. We settled on using a simple GenServer process t
