• Mar '26 Notes

  Mar 30, 2026

  This is my third set of monthly notes for this year. In these notes, I capture various interesting facts and ideas I have stumbled upon during the month. Like in the last two months, I have been learning and exploring algebraic graph theory. The two main books I have been reading are Algebraic Graph Theory by Godsil and Royle and Algebraic Graph Theory, 2nd ed. by Norman Biggs. Muc

  Mar 28, 2026

  I ran a small experiment with Git hosting behaviour using two demo repositories: cuppa: The original repository. muppa: Fork of cuppa with questionable changes. Name Codeberg GitHub cuppa codeberg.org/spxy/cuppa github.com/spxy/cuppa muppa codeberg.org/spxy/muppa github.com/spxy/muppa f79ef5a exists only on the fork (muppa) but not

• Git Checkout, Reset and Restore

  Mar 12, 2026

  I have always used the git checkout and git reset commands to reset my working tree or index but since Git 2.23 there has been a git restore command available for these purposes. In this post, I record how some of the 'older' commands I use map to the new ones. Well, the new commands aren't exactly new since Git 2.23 was released in 2019, so this post is perhaps six years too late.

• Feb '26 Notes

  Feb 27, 2026

  Since last month, I have been collecting brief notes on ideas and references that caught my attention during each month but did not make it into full articles. Some of these fragments may eventually grow into standalone posts, though most will probably remain as they are. At the very least, this approach allows me to keep a record of them. Most of last month's notes grew out of my

• Nerd Quiz #4

• Deep Blue: Chess vs Programming

  Feb 15, 2026

  I remember how dismayed Kasparov was after losing the 1997 match to IBM's Deep Blue, although his views on Deep Blue became more balanced with time and he accepted that we had entered a new era in which computers would outperform grandmasters at chess. Still, chess players can take comfort in the fact that chess is still played between humans. Players make their name and fame by bea

• Soju User Delete Hash

  Feb 14, 2026

  In my last post, I talked about switching from ZNC to Soju as my IRC bouncer. One thing that caught my attention while creating and deleting Soju users was that the delete command asks for a confirmation, like so: $ sudo sojuctl user delete soju To confirm user deletion, send "user delete soju 4664cd" $ sudo sojuctl user delete soju 4664cd deleted user "soju" $ sudo sqlite3 -table /var/lib

• From ZNC to Soju

  Feb 12, 2026

  I have recently switched from ZNC to Soju as my IRC bouncer and I am already quite pleased with it. I usually run my bouncer on a Debian machine, where Soju is well packaged and runs smoothly right after installation. By contrast, the ZNC package included with Debian 13 (Trixie) and earlier fails to start after installation because of a missing configuration file. As a result, I was f

• Twenty Five Years of Computing

  Feb 06, 2026

  Last year, I completed 20 years in professional software development. I wanted to write a post to mark the occasion back then, but couldn't find the time. This post is my attempt to make up for that omission. In fact, I have been involved in software development for a little longer than 20 years. Although I had my first taste of computer programming as a child, it was only when I e

• Jan '26 Notes

  Jan 29, 2026

  In these monthly notes, I jot down ideas and references I encountered during the month that I did not have time to expand into their own posts. A few of these may later develop into independent posts but most of them will likely not. In any case, this format ensures that I record them here. I spent a significant part of this month studying the book Algebraic Graph Theory by Godsil a
