Personal data storage is an idea whose time has come Data Ownership as a conversation changes when data resides primarily with people-governed institutions rather than corporations.

The web can be made personal again.

Uses deepgram, the nova-3 model is very reliable for English, nova-2 is pretty good at German. nova-3 multi is pretty bad. But for realtime transcription still better than the smaller whisper models.

GitHub - rksm/gnome-voice-input: A voice input utility for the GNOME desktop that transcribes speech using Deepgram and inserts text into the currently focused field.

Claude works, which is sort of unbelievably amazing.

In any case, I've gone over to do way more with speech-to-text input than before. Didn't really find a reliable working solution for Linux/Gnome and created github.com/rksm/gnome-v... or this.

And yes, this blurp was meant to troll (which it successfully accomplished). What makes me really sad is that this attitude is now (world)widely picked up and taken for β€œwhat Silicon Valley really is like”. For that reason alone, thank you for going on air and giving a different account.

But by completely disregarding the past, folks miss out on many insights that have not been popularized, and yes, are bound to repeat the mistakes made. If you then layer this amount of arrogance on top, the result is disgusting. Even if money is the objective, this is so harmful in the long run.

I think you touched on this in your conversation quite well. Even in this short time, there has been a tremendous amount of work and innovations that made the modern digital world possible. It’s easy (maybe to a certain degree even necessary) to mask out the details to act in the here and now.

Plus: a number of avenues that have been touched upon in the 70s and 80s but never really followed on thoroughly. I'm sure there are many more good business ideas hidden in the past.

"Dealers of Lightning" and "The Dream Machine" are very enjoyable reads and shed some light on how much work went into all this. I wish more people would be interested in how this all came to be.

Trumpismus und Putinismus sind BrΓΌder im Geiste. Der Transatlantizismus durchlΓ€uft so eine Polumkehr. Illiberale pro-Kreml KrΓ€fte in Europa (die Orbans, die Weidels, die Ficos), die die USA bisher verachtet haben, sind schockverbliebt in MAGA. Liberale Demokratie ist nun von allen Seiten unter Druck

Logic Game, 2005.

I made this logic circuit simulator to learn Etoys, Alan Kay & co.'s programming language for kids. I represented the state of the wires and logic gates with their "costumes" -- there is no hidden state. This makes the behavior of the circuits visible.

Similarly: computational efficiency as in energy consumption. This is not just a PL question but also deployment and runtime behaviors. How to design applications for a low CO2 footprint? There is academic research but little has trickled down so far.

Why STUNner - STUNner

Learned about STUNner, a TURN server that acts as an adapter between WebRTC servers <-> kubernetes. This used to be painful with coturn; STUNer works like a charm. In combination with webrtc.rs or pion, this enables quite a few new avenues for video streaming and more!

Text embeddings are the real "AI" invention. LLMs are clever in how they manage the token context but I think much more can be build with technologies based on models like BERT. Not only is this stuff more reliable, it is also much more versatile, easier/cheaper/faster to run and fine tune.

It is possible to build Tailscale in a weekend. We did that and have been debugging it ever since.
