Local-first software is also a new business model among the other cool tech stuff. With this, software becomes true commodity as it was in early 00s.
It pushes tech vendors out of their comfort zone. I believe revolution will happen bottom-up when customers will insist.

Unless you operate on a very niche market, like Ditto. In general, I think, closed source DB is a hard sale. This is why I think the futo.org model of “source first” should work well.

Lovely post by @antirez.bsky.social about his thoughts on DB open source market and how hard it is to balance so a DB development process is funded.

The DBs situation is particularly tough since it’s related to customers data, so must be open source.

Was hoping to quickly spin up an AWS x86 EC2 instance to debug issue with fuzzing on native machine.
Man that was exhausting and I haven’t even got to have an instance running to connect to.
Why it’s that ridiculously complex? Is it a skill issue?
We can do better here.

> Canonical source code for software should include checksums of the content of all its dependencies.
By Alex Kladov, matklad.github.io/2024/09/03/t...
The language dependencies are the simplest part, the compiler part is non trivial. This is where Nix comes to rescue.

Perplexity fully replaced Google for me. It’s so much better experience.
However, I don’t really know what to expect when it (eventually) turns into an evil corporation as Google did.
Google it harmless in a sense, all it does is targets me using regexp.
But LLM can do better against me?
