Okay, so either Deno's OpenTelemetry metric “http.server.active_requests” (https://docs.deno.com/runtime/fundamentals/open_telemetry/#http.server.active_requests) is actually cumulative over the lifetime of the process, or I have found the explanation for why […]

I'm back from #ecscw 2025! 🙂 Well, I have been for a few days, but I've also remained super busy in the aftermath.

The poster presentation for https://fietkau.science/orcid_fediverse_public_information went well, I had some nice discussions and introductions […]

Took me a while to take a nice photo, but two weeks ago I got my stuff from @MoonloreDraws's last Kickstarter: https://www.kickstarter.com/projects/moonloredraws/30-little-guys-part-2

When it came to picking my supporter rewards I kinda just did “one of […]

I have written down my privacy-first design process for @encyclia and how it relates to Fediverse standards and social norms, and turned the result into a poster presentation for the upcoming ECSCW 2025 conference. 🙂 […]

I've started publishing my “Introduction to human-computer interaction” slides as CC-licensed reusable teaching material. (My #oer debut!)

https://fietkau.science/teaching/intro_hci

I've been wanting to share these for more than a year. Doing that all at […]

I made a small change to my list of academic profile links at https://fietkau.science/publications earlier this month. Kicked out some Elsevier stuff in favor of OpenAlex. Their profile of me was already pretty good, all I had to do was let them know that […]

The last "big" code thing I need to get done before the alpha test of my current @fedify project is the task queue - make sure routine data updates happen, consider individual importance and urgency, respect external API rate limits, etc.

But that's super […]

Excerpt from an email I got this weekend.

On the one hand I like that people are looking out for pitfalls, but it's also a shame that such a simple technology as QR codes is so rife with scams and exploitative products that caution is necessary.

I do all official correspondence via email when possible, but I live in a country that relies a lot on paper. Luckily I'm also passionate about physical filing systems and very good at bureaucracy. 😄

Here's part of my physical folders. LTR: Job, finances, medical, clubs, insurance, apartment.

With #fedijam nearing its deadline, I've been working on customization and accessibility options for my game. 🙂

Yes, it's a game jam, and this is one area of many where jam games typically cut quality corners to save dev time. But accessibility has kinda […]

Unveiling the core gameplay loop of my #fedijam entry. 😀 Think you can do better than me? You're probably right! Prove it next month!

Note: still placeholder graphics, have not even started on presentation except basic animation. I wanted to get the […]

Finally starting on my #fedijam project today. 😀 Because is it a real deadline if you don't start on the thing halfway through? 😇

This is after an hour or two of getting warmed up again in #threejs. Hand-fudged physics, no graphics yet, but you can guess […]

Alright! With that journey wrapped up, maybe now I'll manage to make time for some open source / fedi software work over the next few weeks before courses start? I dunno, but I'm motivated. 😎

Good morning! 🌞 After a negative COVID test and a nice breakfast, I'm off to the #muc2024 opening keynote. Letting myself be surprised there, didn't research who's presenting.

I can't help but feel I lucked out with the hotel that the travel department […]

Settled into my Hotel in Karlsruhe for #muc2024 and finished last preparations for tomorrow's presentation about a human-centered perspective on #HCI studies involving body tracking sensors (Kinect etc).

This is in the context of a research methods workshop […]

I finished another #webdev side project and built the QR code generator of my dreams: :fietkau_software: https://fietkau.software/qr

* It's instant, purely client-side, and has no ads or upsells.
* It has a variety of color, shape, and logo embedding options […]

Spending part of this week #writing about failure! Going ahead and assuming it's been long enough that no one will get mad at me for this. 👀

Hah, no way, my dinky little Bluesky bridge project https://fietkau.software/pinhole got linked in a @TechCrunch article:

https://techcrunch.com/2024/06/05/bluesky-and-mastodon-users-can-now-talk-to-each-other-with-bridgy-fed/

I'm glad it's been surpassed in usefulness. 😄 Cheers @Sarahp and @snar…
