tl;dr: A long list of what I used to replace iOS apps when I switched to GrapheneOS. In the last year or so I’ve been working on taking back control over my means of computation, starting with my main computer, but also where I host my code and how I host some of the things I use.

tl;dr: Here’s a small addition to how you can also scramble images so that “AI” scrapers will end up with a poisoned data set Earlier this year, I’ve written about how I setup this static website to not only serve human-readable data, but also “poisoned data” to mess with the scrapers that are used to collect the training data sets for generative “AI”. As static website deployments via Codeberg Pages et al. aren’t offering a

As this blog post is being published, we are sending out emails to all openSNP users with some news: OpenSNP will be turned off – and with that also delete all the data stored on it – on April 30, 2025 . Given that the project has been part of my life for so many years and shaped how I view (data) commons and open &

tl;dr: I made a small contribution to MapComplete that allows adding/editing wayside shrines to OpenStreetMap. Argentina is full of little way-side shrines, to saints recognized by the Catholic church such as San Expedito but also to folk saints that are not recognized by the church, like Difunta Correa and Gauchito Gil.

Over the past few weeks, I’ve been working on migrating the website of the Open Bioinformatics Foundation (OBF) from being run based on a self-hosted Wordpress blog to Hugo . I thought it would be nice to share a bit of background on the requirements and the how & why the migration was done.

Just a small public service announcement: If you’re using the Gemini protocol, my webste (well, in particular the blog posts), are now also accessible via Gemini at gemini://tilde.club/~gedankenstuecke/. You can also find a web-proxied version here. If you have no clue what this means: Gemini is a small, alternative internet communications protocol browsing remote documents, similar Gopher.

In mid-2024, I’ve moved back to using vim as my main text editor, both for code and prose like this blog post. Something like 15 years ago I had dabbled a bit with vim, but never much more than being able to perform simple edits and get the hang of the hjkl navigation. Good enough to quickly make minor edits from any shell, but not a whole lot more.

tl;dr: Blog posts here can now have a little button at the bottom that can pull in “comments” that are made by replying to a post on the Fediverse (i.e. Mastodon et al.). Some days ago, I saw the nifty little “comment” integration that FOSS Academic Robert W. Gehl has on his blog, which in turn were inspired by some other integrations.

Science that’s not just made by and for white men is under more-than-usual attack these days, thanks to the new administration in the USA under the leadership of Trump/Musk, which made a directive to remove all mentions and funding for initiatives relating to diversity, equity & inclusion (DEI) on January 22, 2025.

tl;dr: Here’s a how-to for adding some “AI”-poison to your static site that’s hosted on Codeberg Pages (or GitHub Pages ). I’d appreciate some feedback on if this is useful/how it could be improved. If you’re running any type of website in 2025, you’ll likely be suffering from the impact of generative “AI”. Be that “AI”-generated spam posted to your site, crawlers bringing your server(s) down or just having
