    Project mention: Vimium – The Hacker's Browser | news.ycombinator.com | 2024-10-21

    I'm surprised no one has mentioned Surfingkeys https://github.com/brookhong/Surfingkeys. I switched over from Vimium a couple years ago. I think its more performant than Vimium and also allows you quite a bit more flexibility in your configuration.

    I prefer and recommend browser add-ons over Nyxt. You'll get more compatibility by being able to use Chrome/Firefox. You'll also have a much higher chance of being able to use the same environment at work - since you can typically still install browser add-ons in developer mode even if you aren't able to get rights to install apps.

    Project mention: Coming Full Circle: It starts and ends with Git and GitHub | dev.to | 2024-12-06

    Browser Extensions: As mentioned in my previous blogs when I worked on the ImprovedTube extension - I have recently been invested in learning more about browser extensions. The work I did for Le Git Graph, has taught me about the complexities of integrating with existing web applications (you have to know a lot about GitHub's interface in order to manipulate it!). Working on this extension made realize GitHub's dynamic nature requires me to carefully handle different page states and navigation patterns - and even then, there might be things that change and I'll have to update the code accordingly.
