Made some Python to convert MIDI signals from a Yamaha FGDP-50 to play Hang Drum samples: instagram.com/p/C-IuQ4loS0f/ Very satisfying dulcet sounds wafting through the house on this summer evening.

Modern SQLite #1: STRICT Tables I'm starting a series of short notes about handy SQLite features you may not have heard about. And the first one is "strict" tables. As you probably know, SQLite's type system is very flexible (some people even call SQLite the JavaScript of databases) — you can store any value in any column type (e.g. create an INTEGER column and store text values there, or a REAL with blob values). Some people love SQLite for its flexibility, others hate it for the same reason. So at some point the SQLite authors introduced STRICT tables. They check types the same way other DBMS do (see the screenshot). Even with strict tables, you can still explicitly declare a column as ANY — such columns can hold values of any type. So you can have the best of both worlds — strict type checking and type flexibility. Available since SQLite 3.37 (Nov 2021).

Super happy to see this announcement. I have been considering making a super-simple read-only *.ipynb viewer for the console in Textual for months now. But voila! The cool froods over here have done one better. I am not the only one wanting this...
Just like JupyterLab, jpterm now has a top bar in the notebook editor. In the future it will have buttons to run cells, interrupt execution, restart the kernel, etc. But for now there is only the kernel busy indicator. Still, I think it's kind of neat 😄

Blog 4 voor de Preservation Watch van @DigitaalErfgoed over Large Language Models, digitaal erfgoed en preservering is nu online te lezen. Deze keer mocht ik Etienne Posthumus @epoz@blog.epoz.org en Bob Coret @coret interviewen over hun ervaringen
Benieuwd hoe ongestructureerde data worden gestructureerd en gematcht met gecontroleerde vocabulaires voor een museumtool? Of hoe een ChatGPT-plugin kan helpen bij de vindbaarheid van digitaal erfgoed? Lees de blog van Heleen Wilbrink kia.pleio.nl/groups/view/4fc…

Do you need to do large RDF extracts or long-running complex queries of Wikidata? Here are the slides of an internal seminar I gave to colleagues last month on a solution for the above: docs.google.com/presentation… And code at: github.com/ISE-FIZKarlsruhe/…

It has been working really well for me, curious to hear your thoughts on the idea.

Shout-out to the vocabularies team at @GettyMuseum - the vocab.getty.edu/ LOD endpoint is a joy to use for the power-user. 🙏 💪 Using it for some German/Dutch/English museum description reconciliations and it works a treat.

Gaussian Splattings are absolutely amazing in themselves - and here is a whimsical yet beautiful abuse of them. It gives me the same sense of wonder as the first time I saw a bullet time rendering.
Another experiment with Gaussian Painters ✨🎨 By optimizing 3D Gaussian Splattings over separate images at several viewpoints, it is possible to get a Steganography effect! Three paintings are hidden in those gaussian splats

How do y'all handle (large) n-triple files with bogus URIs in them? Most triplestores accept URIs with unencoded characters like [ and ] in them, but certain ones are all strict and barf. I could iterate over the input and "fix" it with a script, but this is tedious. (and slow)
