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.

Trumpismus und Putinismus sind Brüder im Geiste. Der Transatlantizismus durchläuft so eine Polumkehr. Illiberale pro-Kreml Kräfte 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

Catching up with my podcasts, what an amazing interview!
Within software architecture, few people shaped the industry as much as @gradybooch.bsky.social. Safe to say he's a true legend.
In today's The Pragmatic Engineer Podcast episode, he shares fascinating stories, insights, observations.

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.

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.
Wrote up my notes on ModernBERT, the brand new modern alternative to 2018-era BERT released by @benjaminwarner.dev and @howard.fm and team simonwillison.net/2024/Dec/24/...
Finally, a Replacement for BERT: Introducing ModernBERT
[BERT](https://en.wikipedia.org/wiki/BERT_(language_model)) was an early language model released by Google in October 2018. Unlike modern LLMs it wasn't designed for generating text. BERT was trained ...

It is possible to build Tailscale in a weekend. We did that and have been debugging it ever since.
interesting to see it called "from the archives" when its like a huge part of their marketing strategy to convince people that they can't just build the same thing themselves in a weekend (the anti-dropbox-hn-comment pill) . also its linked on the footer . very good article though
From the Tailscale archives: "How NAT traversal works," a deep dive into some networking fundamentals that remains one of our most highly read posts

I see so much FUD about the future of sw engineering, mostly from non-devs. Along the lines of “soon anyone can spin off AI agents in bulk that act as hundreds of devs.”
A false premise. Just open your airline app that is built by ~hundreds of devs over 10+ years
