• 16:25 UTC (new) (history) 2025-08-18 Cutting clips from videos with Emacs . . . . mbork – I often want to show someone a clip from a video. When that someone is sitting next to me, I can just seek the right place in the video and hit “start”. But what if not? What if I’d like to upload the clip somewhere, or maybe even email it? Or just I don’t want to search for the right place, or risk showing too much of the video (which might contain spoilers, for example)? Now, the first answer that comes to my mind is to extract the clip to a separate video file and play that instead. Of course, if you know me even a bit, you won’t be surprised that I’d like to do that from within the comfort of Emacs.

• 15:37 UTC (new) (history) 2025-08-11 Using Eldoc to show entities with given uuids in the echo area . . . . mbork – This is the culmination of my series of posts on customization variables, timestamps, ElDoc, PostgreSQL and interacting with potentially unreliable external processes via stdin and stdout. All the time, my goal was to be able to show the database row corresponding to a uuid when the point is on that uuid. Since most of the hard work was already done in the preceding six posts, this one will be rather short (not including the code itself).

• 04:20 UTC (new) (history) 2025-08-04 org-copy-visible . . . . mbork – I have a short tip for today. Sometimes I want to send myself my Org mode agenda for today in an email so that I can open it on my phone. (Yes, I know, this is not the optimal way – I’m currently experimenting with Organice, I’ll check Orgzly, too – but sending an email to oneself and opening it on one’s phone is not as bad as it seems.) One problem I had was that Org links were not very legible in a plain text setting. Of course, one of the promises of Org mode is that it is plain text – but still, I don’t really need to see the URLs when I just want a quick reminder of my tasks so that I can do some of them on the go.

• 07:10 UTC (new) (history) 2025-07-26 Finding entities with given uuids in the current project . . . . mbork – One of the Node.js projects I work on has some fake/seed data in JSON files. These data are inserted into the local database during development. (Your mileage may vary – you might use Knex for seeding, or you might have your seeds as csvs or even sql files with a bunch of insert​s.) Of course quite a few tables contain some foreign keys. Sometimes I open one of the JSON files of such tables in Emacs, for example to edit some data – but it is often the case that the related data (pointed to by the foreign key) should also be changed. In cases like this it is very useful to be able to find those related data quickly. Some time ago I had the idea that it would be great if I could easily see all the data about some entity when the point is on its id.
