I see a narrow path where AI can eliminate the entire concept of the powerpoint presentation.

@Heidiaca 7 wins. Could be ten but every three weeks a different team shows up.

[Dan Olson @olson_dan]

I very often have no idea what I'm doing. But I appreciate that AI allows me to have no idea what I'm doing in a way that's disruptive to people who do know what they are doing.

@charliermarsh Anything legitimately good gets upstreamed. Everything else is caveated into uselessness I guess.

[Dan Olson @olson_dan]

@oheyspun I'm already there, but part of it is how toxic forever was at the end of the beta if you didn't hit 30 when everyone else did.

[Dan Olson @olson_dan]

Having returned to both recently... gameplay-wise retail is a lot better than forever. Socially, forever is a lot lot better.

[Dan Olson @olson_dan]

It is pretty kickass when something you randomly wrote 8 years ago becomes an extremely useful reference for AI-driven tasks.

[Dan Olson @olson_dan]

It's fun how you can instantly recognize AI-authored PowerPoints. This isn't a slight on anyone doing it. This is one thing that we blessedly never have to do by hand again.

Goose not crashing is a fantastic Goose-related advance since 1986.

[Dan Olson @olson_dan]

> The stress pass found no Goose crash or timeout in 250 structured differential cases plus 100 random binary inputs.

[Dan Olson @olson_dan]

This was one of the few times in the show that I thought a character was just about to make a good decision.

[Dan Olson @olson_dan]

A very discouraging day, but with real progress on interesting stuff as well.

[Dan Olson @olson_dan]

The results were heavily caveated by the AI, hopefully the second pass will be even better.

[Dan Olson @olson_dan]

I have a vibe coded Rust version of a C++ preprocessor that is markedly faster than closed+open source versions I have to use. Asked AI to port it to Goose, got 1.07x speedup over the already fast Rust in first try. @wvo

[Dan Olson @olson_dan]

@stoolgambling Nix is really disrespecting him here.

[Dan Olson @olson_dan]

@lucasmeijer Mine is very simple, just one round of review, but I'm thinking of not using it anymore because it slows everything down significantly while only improving code quality and rework a little.

[Dan Olson @olson_dan]

Not a fan of this happening in the middle of a work day.

[World of Warcraft @Warcraft]

Good News, Everyone!

Starting Oct 27, reserve your first THREE characters’ names for WoW: Forever!

The Beta is also extending to 10 AM PDT on Oct 23 🚨

Right now the thing I want most is about 4x faster inference.

[Dan Olson @olson_dan]

Every once in a while some celebrity whose entire career has been totally invisible to me will show up as the thing the algorithm thinks I should see seventy times a day, because they released a movie with a production company whose entire output has been invisible to me.

[Dan Olson @olson_dan]

Download rustc source -> “Do a breakthrough”.

Not as interesting as any of this but took my rust workspace tests down from 40 minutes in CI to 8m full, <5m incremental last week.

[Charlie Marsh @charliermarsh]

We're starting to see some agentic Rust forks (or alternative implementations) focused on iteration speed.

More-so than the specific projects, I'm interested in the ideas being explored (and how they could evolve upstream), so wanted to collate a few here...
