149: Elixir's new Unified Logger
Thinking Elixir Podcast
More Optimizations in the Compiler and the JIT
The Erlang folks created a new blog post on their website called more optimizations in the compiler and the JIT. The most noticeable performance improvements in OTP26 are better matching, construction of binaries using the bit syntax. And these combined with the changes in the base64 module makes encoding to base64 about four times as fast and decoding about three times as fast. I'm very much looking forward to it.
Hauleth (Łukasz Jan Niemier) takes us deeper into the Elixir and Erlang loggers. He recently closed a 3.5 year old bug on the ElixirLang Github project by unifying the Elixir logger with the logger that Erlang got in OTP 21. We touch on the history, why it took so long, what we should think of the new logging levels, and what the original goals were that he set out to achieve. We also get an introduction to the new logging filters and handlers along with some peeks into future Erlang logging features that may still be yet to come in Elixir!
