Rebasing in Magit

Magit is a TUI interface on top of git, and it sits in the sweet spot where it makes common Git operations faster, rare Git operations easier, yet still insists on teaching you command-line Git, making you a better Git user. It's a pretty magical experience. Here's how rebasing works in it.

Getting to know you

I have some questions I would like to ask you over the coming weeks. Some of the results may end up in aggregated form as illustrative examples in future articles. Others might inform my writing.

This is about the banner images I have included at the top of each article. This article it pictures an arborist in a tree, and in the previous article it pictured a person cycling through a clearing.

Flashcard of the week

When I read Google's Site Reliability Engineering book I already knew much of what was in it, but one thing struck me as particularly insightful.

What does it mean to escalate a failure?

I had never heard of this before. Escalate an incident, or a ticket, or an alert, sure. That means to pass it on to the wider team, or a subset of it. But escalate a failure? It's possible to guess what it means.

Deliberately making a failure worse, e.g. by taking down an erroneous service entirely.

Reasons to do this might be related to PII leakage, data consistency, or other interaction problems where the broken service is trying to break other services too. It makes complete sense, but in many of the environments I had worked up to that point it would have been unthinkable to intentionally make a problem worse!

Premium newsletters

The most recent premium newsletter was very long and it left me kind of exhausted. I want to write something interesting for premium subscribers, but not something that is too interesting, because the things that are really interesting should go on the public blog!

I am drafting the next premium newsletter, though. In it you may find some discussions on finding good work, forecasting, writing books, and a bunch of external links.

The most recent newsletter before that had a long article on implementing pathfinding for the board game Den Försvunna Diamanten, as well as rationales for my forecasts in the ACX 2026 prediction contest. By subscribing, you get access to this and all past newsletters too.

You might not think any of the above is interesting, but you'd still like to support the blog. You can do so for $4 per month, cancelable any time with no questions asked. To upgrade, click on the link in the footer in the email.
