    Balance of Power: A rematch served cold

    On November 1, 2022 By Hans Petter Jansson In Computing, Technical

    A happy reunion with Chris Crawford's hit geopolitics simulator Balance of Power (1985), with gameplay and code analysis.

    Let it snow '21

    On December 21, 2021 By Hans Petter Jansson In Computing, Life, Technical

    Amidst the holidays that perhaps aren't turning out exactly as hoped, one can take comfort in small tokens of continuity – like the fact that xsnow is still being actively maintained.

    Chafa 1.8: Terminal graphics with a side of everything

    On September 16, 2021 By Hans Petter Jansson In Computing, Technical

    The Chafa changelog was growing long again, owing to about half a year's worth of slow accretion. Hence, a release. Here's some stuff that happened.

    Chafa 1.6.0: Wider

    On January 18, 2021 By Hans Petter Jansson In Computing, Technical

    Here's another one from the terminal graphics extravaganza dept: Chafa 1.6.0 brings fullwidth character support, so in addition to the usual block elements and ASCII art, you now get some mean CJK art too. Or grab as many fonts as you can and combine all of the Unicode into one big glorious mess.

    Chafa 1.4.0: Now with sixels

    On April 1, 2020 By Hans Petter Jansson In Computing, Technical

    April 1st seems like as good a time as any for a new Chafa release — though note that Chafa is no joke. At least not anymore, what with the extremely enterprise-ready sixel pipeline and all. As usual, you can …

    Chafa 1.2.0: Faster than ever, now with 75% more grit

    On August 5, 2019 By Hans Petter Jansson In Computing, Technical

    For all you terminal graphics connoisseurs out there (there must be dozens of us!), I released Chafa 1.2.0 this weekend. Thanks to embedded copies of some parallel image scaling code and the quite excellent libnsgif, it's faster and better in …

    desktop-file-utils 0.24 released

    On July 26, 2019 By Hans Petter Jansson In Computing, GNOME, Technical

    One thing one can do in this amazing summer heat, is cut the 0.24 release of desktop-file-utils. It's rather a small thing, but since the last few releases have been happening at roughly three-year intervals I felt it merited a …

    Battle of the Bilerps: Image Scaling on the CPU

    On July 8, 2019 By Hans Petter Jansson In Computing, GNOME, Technical

    I've been on a quest for better bilerps lately. "Bilerp" is, of course, a contraction of "bilinear interpolation", and it's how you scale pictures when you're in a hurry. The GNOME Image Viewer (née Eye of GNOME) and ImageMagick have …

    The worst ANSI art renderer, except for all the others

    On January 7, 2019 By Hans Petter Jansson In Computing, Technical

    Chafa (github) started out as a small piece of supporting code for an obscure personal project I may announce at some indefinite point in the future. Then I decided to release it as a tongue-in-cheek thing for the VT100 anniversary …

    What ails GHashTable?

    On August 29, 2018 By Hans Petter Jansson In Computing, GNOME, Technical

    I promised a closer look at GHashTable and ways to improve it; here's that look and another batch of benchmarks to boot. This time around I've dropped most of the other tables from the plots, keeping only khash and adding …
