Introducing Rexbug
tracing on the shoulders of giants
Towards the end of November I gave a flash talk at the
London Elixir Meetup.
This time I was talking about the journey from println debugging to
proper tracing and bringing Erlang tools to Elixir programmers.
You can watch the talk here:
…and here are the slides:
The resulting Rexbug project is ready to be used but there’s still some issues I could use some help on - some should even be suitable for Elixir beginners.
Crawlie
Elixir London Meetup presentation
Last year, I saw José Valim give his keynote at the ElixirLive conference in Warsaw, where he talked about the motivation for his new Elixir libraries: GenStage and Flow. Even though I heard about those before, it was the keynote when I “got” what the libraries were good for and why they were neat - and I decided to play around with them.
When I came back to London I started working on a small project that would make use of GenStage and Flow - Crawlie the crawler. Since then the project took shape and allowed me to learn a bit about concurrent event processing pipelines in Elixir. As I’ll probably be ramping down the work around Crawlie now to focus on other things (I have my eye on Riak Core and architecting distributed apps in Elixir in general) I thought it might be a good idea to share what I have learned with others who want to try GenStage and Flow.
Here are the slides if you want to click along or copy the code:
Atom as an elixir IDE
July 2019 update:
I have since moved to neovim for all my Linux/OSX work, and I’m very happy with it. The information here is probably very outdated, but I’m leaving it here for posterity
You can see my neovim configuration in my dotfiles
Earlier this year I joined Mainframe as a backend engineer. I didn’t do any real development in elixir before and I wanted to become productive with it ASAP. When it comes to elixir there were some good books to help me understand it better, but I also needed an editor or and IDE that would give me the necessary tools without getting in my way.
Here’s a list of criteria I had for my editor:
- Erlang and Elixir syntax highlighting (duh)
- good in-project search
- vi(m) keybindings
- code completion
