Netanyahu:

"Would a country committing genocide plead with the civilian population that it is supposedly targeting to get out of harms way? Did the Nazis ask the Jews to leave? Of course not"

Actually, encouraging Jews to emigrate is exactly what the Nazis did 1933-39.

Ignorant of Jewish history.

The more I dig into generative AI from the prospective of a retired person, the less I want to be involved, or make use of the tools.

I want to focus on using my own model of the world to contribute to society for as long as possible.

Announcing Dial, a Rails application profiler: github.com/joshuay03/dial

I've longed for a free tool that provides Datadog-like profiles, with accurate GVL and GC activity. Thanks to @jhawthorn.com's amazing work on Vernier, all I needed to do was integrate it with Rails and let it do its thing.

Given that Trump wants travel bans for even more countries this time around, this would be a great moment to move engineering conferences to countries that require less to no paperwork to visit for many more people.

This is the last subject I wanted to talk about before I can start talking about Pitchfork itself.

What I think Ractors are useful for, and why that isn't writing web servers:
