@Codeberg@social.anoxinon.de seems to bet on nonprofit, common sense, cost-efficiency, minimizing tragedy of the commons-effect, laws of thermodynamics.

purchased some mosquito-repellent plasters from the pharmacy.
They work quite well so far.

It made me think about Mosquito-attracting plasters...would not be a fun prank 😅

Im grateful for celebrating the coffeemachine-phase of XR/AR/VR/MR.
So much genuinly interested people in the space (now the hype is over) 🫶

@utopiah@mastodon.pirateparty.be @ptrpaws@wetdry.world this could be an interesting thought-experiment, especially now the big guys are no longer sucking all the air out of the VR room. Monado as WebXR backend for webkit. Monado SLAM https://www.youtube.com/watch?v=zVZVE4akWn0

Realizing the ephemeralness of online networks (and its software):

Sure, we can try to "build something better without repeating the mistakes of the past" (by introducing complexity X Y and Z).

But perhaps exactly the absence of X Y and Z made it popular in the first place.
When does supersecure supersovereign become super in-accessible?
What if enshittification is not only a corporate thing 😅

ooofff...I've got my AI-caution pill for today.

I do apply the 'retrieve instead of synthesize'-idea in my daily (local) llm-as-dictionary workflow...i like them as dictionaries and encyclopedias...too bad there isn't a single equivalent textfile of that data (which I could grep instead).
Would be cool though: all wikipedia titles + summaries in one textfile.

UPDATE: there is! https://www.kaggle.com/datasets/kirauser/wikipedia-dataset

If you're looking for a highlevel esperanto: Lua is 33 years old and still a great pick.
It's a minimalist VM in ~250kb :

It sits nicely inbetween game/embedded/wasm/web/VR-dev, and feels like ruby meets javascript, without the bloat.

I think the biggest hurdle for the post-american post-monoculture corporate internet is:

monoculture- & analytics-fetish

Decentralized alternatives (fediverse) are pushing back on this; great for individuals, not businesses.

It also explains the EU's love/hate relationship with the silicon valley-stack.

realisation: I seem to get interested in pioneering tech, and not so much in overmature 'streaming' or 'realism' layers of the tech.
I love observing ideas which are different, futuristic, abstract or minimalistic.
For example, a cute pixely banana-GIF, or funny symbols:
▘ ▙ ▚ ▛ ▜ ▝ ▞ ▟

Not even sure if I agree with myself here, but using computers as TV's is when things get boring?

We've made some great progress on being able to render AFRAME scenes inside Janusweb.
Soon we will push out a new release of http://janusxr.com so you can start playing with it.

@aral@mastodon.ar.al TBH whether the CEO believes this agentic poetry or not, at best it reads like an agentic excuse for replacing expensive/senior employees with cheap juniors.. But if they truely believe this poetry...then Im afraid it will be an expensive experiment.

Perhaps the retrogaming community isn't just about nostalgia—they’re accidentally building a better, faster, and more functional internet than the one we have now. 🕹️🌐
By stripping down remote resources to their essentials::

Makes me wonder which HTML features are 'good enough' to not enable grifter economies.

RE: @_elena@mastodon.social

interesting paradox: decentralisation (like Activitypub, Radicle-dev, Gemtext, Janusweb) makes networks more resilient but also invisible.
Security by obscurity.
Go for it..go make your centralized visible fork..good luck with that.
Mastodon has never cared to be a central player...the point is webfinger + activitypub.
ps.I love that the article mentions ActivityPub ❤️

Lua has many dialects, and I love them all ❤️
But how to write one lua-file and target them all?
Answer: metaprogramming

Here's a small ~700 bytes gpp-ish metaprogramming awk script 🎉

ps. its not limited to lua :coolcat:

while most green tech initiatives focus on buying new, energy-efficient hardware, the retrogaming community has spent decades perfecting the art of extreme hardware longevity.

paradoxically, retrogaming has everything and nothing to do with consumerism, nostalgia and permacomputing.

Léon van Kammen @lvk@mastodon.online · Apr 23, 2026

awkward fact: my (client) websites keep breaking..since the 90s 😅

With more and more devices in different forms and shapes..
These days NETSURF seems to be the middleground for testing webpages.
Just enough CSS, just enough javascript, bit of webdev tooling ❤️
If it works there, then it works on smartwatch (textmode) browsers & chrome too.

@utopiah@mastodon.pirateparty.be that's a good point..energy is extremely easy to measure (multimeter in videoreviews e.g.)

@terminaltilt @zerodogg to be pedantic: afaik pragmatism is not the death of understanding, perhaps the overuse of AI is. I love pragmatism, as its uses abduction to arrive at actionable outcomes. AI pullrequests only deals with deductional truths, which is a very incomplete perspective (which is wat pragmatism advocates against).

Replying to @cirku17@puntarella.party

a big blind spot to 'the next big network', is the assumption that hightrust ecosystems attract people. The reality is that people are very tolerant to low-trust environments.
