vorpal.se is a personal blog at vorpal.se about hardware and programming. Since 2025, 4 different Hacker News readers have linked it 6 times, most often “Filkoll – The fastest command-not-found handler”. It is still writing: the last post was on 2025-06-22, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
A personal blog by a developer. Linked posts cover a fast command-not-found handler for Arch Linux, its design, and reverse engineering ACPI on an old Toshiba laptop.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
This is generally called a command-not-found handler and are a feature of all the major shells (though the exact details differ, the general idea is to define a function with a specific reserved name), and most majors distros have ones that can be installed, even if they aren't by default. I wrote my own (much faster) such handler for Arch Linux. I even wrote a blog post about the design: https://vorpal.se/posts/202…

HN discussionI think PrusaSlicer does this in a reasonable way. (Context: this is software for preparing files for 3D printers.) It has three modes: Simple, Advanced, Expert. They are all the same UI design , all it does is hide some less common settings to not overwhelm users. Each level is also associated with a colour, and next to each setting is a small dot with that colour: this allows you to quickly scan for the more commo…

HN discussionI did some ACPI reverse engineering on an old Toshiba laptop some years ago, with the goal of improving the Linux ACPI drivers. Learnt a lot from it, and wrote a blog post that you might find interesting: https://vorpal.se/posts/2022/aug/21/reverse-engineering-acpi... (100% human written, and I hate that I have to specify that these days).
