No wonder, I hardly ever use TeX anymore – but I still do use it from time to time! A few days ago I needed to draw a diagram of an inclined plane. Interestingly, there are people who did exactly that using TikZ before (obviously), but two examples I found used the heavy artillery of trigonometry.

• 09:56 UTC (new) (history) 2022-01-29 Running a script before (and after) starting the psql prompt . . . . mbork – And here I am again, with another PostgreSQL tip. Recently, I had a need of running psql interactively but executing some script first. Of course, this can be done from psql itself by saying \i some-script.psql, but let’s assume that I’d prefer for that to happen automatically, so that instead of typing psql at the shell prompt and then \i some-script.psql at the psql prompt I could just say psql-some-script.sh at the shell prompt and be done. The important thing here is that I want to run some-script.psql first and go to the psql prompt next.

• 16:26 UTC (new) (history) 2022-01-24 Journaling with Org-mode . . . . mbork – OK, so let’s admit it. I’ve been journaling with Org-mode for more than 6½ years now. Every day (well, almost every day) I sit down and make notes of important things that happened that day.

• 20:12 UTC (new) (history) 2022-01-17 Making code snippets in Org-mode easier to type . . . . mbork – From time to time people tend to discuss the Org markup – some people want to extend it in one way or another, some people want to make it more Markdown-ish. I tend to agree that the selection of the tilde (~) to denote code is a bit inferior than Markdown’s choice of the backtick (`). But keep in mind this: I don’t have a problem with looking at my Org file and seeing (lots of) tildes. After all, font-lock does a good job of telling me that this is code. I have a problem with typing these tildes, since they require me pressing the shift key – and if I have a lot of small code snippets, this is not very comfortable. Add to this the fact that I happen to write in Markdown pretty often (when I use Markdown-based tools, like Slack or Jira), and I started wondering: why couldn’t I press the backtick in Org-mode to type a tilde (and vice versa so that I don’t lose the ability to type a backtick)?

• 21:59 UTC (new) (history) 2022-01-10 Simple tmux scripting revisited . . . . mbork – Some time ago I wrote about my (very simple) tmux script. Since then I started to like tmux even more, and in fact I tend to create a similar script for every major project I work on. Last time, however, I noted how the sleep part is very fragile (and less than elegant). Since then I realized that I do not need any advanced scripting to run command Y in tmux window B when command X in window A finishes its job. In fact, this is very simple, and I’m ashamed I didn’t think about it earlier.
