What's the story with that slash?

Note: I've been working on the styling of code blocks in technical posts. They should look better than they did previously, and be more aligned with what's discussed in the text. There's still some work to do; if they're

GNSS Positioning - A Reviser

A super comprehensive introduction to GPS, with more detail than I have seen elsewhere. Also based on the second paragraph it seems to be quite up to date (2023)

  • Web site excerpt: This article reviews the core principles underpinning the global navigation satellite system (GNSS). It references some of the key terminology, outlines the main potential sources of error, and describes how the application of RTK DGPS techniques can mitigate these errors to a large extent.

How HEAD works in git

Julia Evans continues with her tour the force in depth explainers about how git actually works.

  • Web site excerpt: Usually when people say that a topic is confusing when I think it’s not, the reason is that there’s actually some hidden complexity that I wasn’t considering.

Marking the Web’s 35th Birthday: An Open Letter

This is a quite interesting letter, advocating the creation of a privately owned data store for every user of the web. It’s a grand vision coming from somebody who has huge influence. that someone is Tim Berners-Lee, the so-called inventor of the World Wide Web. By the way he used the NeXT computer to create the original prototype, which is a pretty interesting historical note.

A decent VS Code + Ruby on Rails setup

An update on vscode for ruby and rails. This stuff is covered all the time but it’s worth seeing it again because the world changes and the recommendations also change.

  • Web site excerpt: Setting up VS Code for Ruby on Rails development can be tricky, so I wrote this article to help. In it, I share different VS Code extensions for things like autocomplete, linting, formatting and more! I've even put together a handy extension pack to get you setup fast.

Running Rails on AWS Elastic Beanstalk

Interesting because it is comprehensive. However with that level of detail comes a great risk of inconsistency caused by evolution of the building blocks.

  • Web site excerpt: Recently, I got a Rails app running on AWS Elastic Beanstalk for the first time. While other tutorials exist, this one walks you through everything you need step by step — even if you don’t have …
