• 20:17 UTC (new) (history) 2026-01-26 A simple but nice PostgreSQL trick with timestamps and nulls . . . . mbork – I had a pretty busy week, so today I only have a short PostgreSQL tip I learned recently. Assume that you have a table of users, and it has two columns containing timestamps: created_at and deleted_at. The former is non-nullable, but the latter can contain nulls (for users who were never deleted). Let’s assume that you want to select all users who existed at some point in time, say today at midnight.

• 18:46 UTC (new) (history) 2026-01-19 Toy train timetable clock . . . . mbork – My son loves trains. Once in a while, we’re playing with electric toy trains. Sometimes this means just having them move around and use switches to change their routes, and sometimes it means building two or more stations and moving actual (toy) people and (toy) wares between stations. Recently, we came up with an idea to level up our game.

• 18:17 UTC (new) (history) 2026-01-12 Making fill-paragraph more flexible . . . . mbork – I wrote recently about fill-paragraph-semlf and how I moved to it entirely with M-q. It quickly turned out that it wasn’t the best idea. Sometimes I want to be able to fill the paragraph in the old way, too. I figured that the best way to do it is to make M-q do that when pressed for the second time.

• 18:32 UTC (new) (history) 2026-01-05 Magit and new branch length . . . . mbork – Like many Emacsers, I am a heavy Magit user. If you use Magit, I don’t need to tell you how great it is; if you don’t, I suggest you do yourself a favor and try it out. That doesn’t mean that Magit is ideal, though. It has some issues, though usually very minor ones. Today I’d like to write about something which is definitely not a “Magit issue”, but rather something I personally miss in it.
