You should normalize by the number of trucks on the road in each category (gas/electric). Absolute number of fires make little sense if you have 1000 times more ICE trucks than electric ones.

This is what happens with you delegate power and decision making to others. At least you did the right thing -- moved out and now you and your wife have full agency and responsibility for your own house.

Mojo?

Mojo looks interesting [0]. It is designed by Chris Lattner himself [1] and has an interesting take on borrowing references (Rust's DNA) comptime execution inspired by Zig. And it targets CPU and GPU (NPU, TPU) as first class targets. Recently reached 1.0 release.

Management should be tried for gross incompetence with some painful consequences severe enough to cause change in behavior. This is the only way.

> you can spit out perfect machine level code against a specification

Typescript team explicitly mentioned the lack of Typescript specification as one of the reasons to choose Go. Typescript as the language is defined currently by its compiler which was Javascript based. Go port is as close to it as possible while Rust would be harder to reach fully identical behavior.

I build it with `cargo build -p codex-cli --bin codex` in under 4 minutes on my old M1 MacBook Pro with 64GB memory compiling more than 1250 crates.

> Everything in low Earth orbit is moving at 7600m/s. A ~10g projectile moving that fast has an energy of 580,000 joules.

What matters is the relative velocity of the projectile towards the target. I practice it will be smaller or larger (if the bullet is incoming). But steering an incoming projectile is way harder.

+1 on Altra. I have Altra FWD and it is far the best running shoes I ever had.

High performance polars dataFrame processing library [0] is written in Rust with Python bindings via PyO3/maturin. It exposes huge dataframes to python and successfully solved the interface boundayr problems described in the article.

Nice work. But I cannot find a link to the actual code of the model or the training data. Did I miss it somewhere?

lr1970 — Wed, 02 Sep 2026 18:44:25 +0000

Ed Zitron is providing his assessment and prognosis strictly on financial basis. But AI has national security and geopolitical dimensions as well. US government is fully committed to keep the AI lead for as long as possible. And they use all sorts of tricks to affect the market in AI's favor. Financial analysis alone is not enough. The government will do anything to prevent AI bubble from bursting.
