A recent hiring process required me to write down a debugging story that included application code and infrastructure. This prompt reminded me of an old happening back in 2016 and how amazingly baffling it was. I didn’t use this event in my job application, but I found it was worth writing down and share, showing the interesting failure modes that big distributed systems can bring.
Read more...I was reading the other day a nice blogpost by Matthew Garret (mjg59) about being able to use SSH keys to sign Git commits. While trying to make that set up in my machine I realized there are some tricks I use to configure the Git repository identities I had not spoken about before, so I’m going to merge both topics.
If you are only interested in the SSH signing, you can check mjg59’s post above and Caleb Hearth’s. If you want my usual ramblings, keep reading.
Read more...As perks of the job, I tend to find myself having to maintain old code bases with many outdated dependencies. That is quite usual, but turns to be specially painful when you need to update a core dependency and every other thing starts breaking due to API changes. This has happened to me in 2 workplaces, first in Ruby on Rails, and latest in the infrastructure scripts written in Python 2.
Read more...Project management is a basic necessity of developing software (and things that are not software). As I use Emacs throughout the development cycle I also need to control projects from there. I’m sharing here a transient I wrote to help me learn to write transients and to use these better.
Read more...I have seen a rise in the number of opinionated tools present in the common mindspace in the last decade. These tools usually cause controversy by limiting user choice and following a set path through problem space. But why have they become popular? Why are they “better”?
Read more...We started a book club at work at the end of 2020 and the first book we went over was the extremely famous Refactoring: Improving the Design of Existing Code by Martin Fowler.

Read more...I try to keep track of improvements in the projects I depend on the most, and sometimes I even track their development with the hopes of being able to contribute something back. One of such projects (though contributing back directly is pretty unlikely so far) is Emacs, and I build it locally to get the big improvements early on.
Read more...Using Emacs, you eventually need to learn Emacs Lisp (elisp) as everything is written in that language. Configuration is also in elisp, but usually requirements are minor enough not to need much learning. I’ve tried to learn it several times with low success, but recently I got to write a helper for myself that I think is worth sharing. This is just beginner stuff, and hopefully will help me remember how the bloody thing works :)
Read more...I recently read Scott Berkun’s, “The year without pants”. For some reason I got the idea that the book was about how to work remotely, kind of a tips and tricks collection, which seemed on topic in the current pandemic situation. Nothing further from truth.
