@zkat@toot.cat After many discussions and observing people talking about it... I came to the conclusion that it makes sense to treat it as a nascent religion (same applies to capitalism, except for the "nascent" adjective, but that's another story).

Facts & reasoning alone might not be enough to combat the rhetoric of those pushing for LLMs & gen AI for everything.

Sadly, we might need another creed to ensure effective pushback. Idk, I think I'd be OK with people honouring "Mother Nature" or something alike.

Slowly, but without pause, our #FLOSS slicer for resin #3dPrinting is starting to take shape :) .

https://codeberg.org/SoulCrafted/Slicer

However, we are not alone, there are other people trying to bring new open source solutions to this space.

In a few days the #OpenResinAlliance ( https://openresin.org/ ) will release a first early access version to their backers on April 1st (no joke), and an open beta on on May 1st.

They started long before we typed our first line of code. So far, from what I saw, they are bringing something awesome to the table.

I hope we'll find ways to collaborate.

It's not like I'm entirely surprised by this https://openai.com/index/openai-to-acquire-astral/

But I find it quite sad. These mega-corporations are trying to own all our stack... we should find ways to build community alternatives to avoid falling into their trap...

But first we should learn our lessons about what constitutes good software. PIP has never been good, that's why `uv`, `ruff` and `ty` are an interesting purchase for #OpenAI. That's the kind of software that we should be building as a community.

I'm happy to announce that since today I'll be leading the development of the #OpenSource SoulCrafted Slicer for resin 3D printers:
https://codeberg.org/SoulCrafted/

Note: The tech coop is still a thing! We are going live soon! SoulCrafted is our first commercial project (as contractors) ✨ .

Lots of work to do!

I'm reading Kurt Vonnegut's "Galapagos".

This is a novel from **1985**... and, while it's not "great", I'd still recommend it for anyone living this current time, plus, it's kinda funny.

It manages to:
- describe AI techno-bros as what they are: self-centred assholes.
- (shallowly) describe incels before those were a concept in our collective imagination.
- (very subtly) establish a clear connection between all those self-proclaimed "apolitical" people and... nazis.

RE: @lobsters@mastodon.social

This, kids, is why when relying on containers, we should ensure that (at least):
1. Their filesystem is READONLY (example: if you are using Python, generate your .pyc files when creating your OCI image, not at runtime)
2. They run under a non-privileged user

And, at the host & network levels:
3. The private network is properly segmented.
4. We have firewall rules to control outgoing traffic and traffic between subnets.

This is not paranoia not overengineering, shit happens, we ought to be careful.

@rachelcoldicutt Not in UK (based in Spain), but I believe it would be a good thing. Do you know by chance of any similar efforts across the EU? (I suppose if there's something it would be good to somehow connect those organizations).
