When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

Here's a tiny bit of hopium:
In 2024 we were planning on adding 160 GW of renewable energy to the grid by 2030.
As of the start of this year, we had added 100 GW and are planning on adding 220 GW more by 2030.
(In 2022 we planned for 60 GW in 2030. We hit that by the end of 2023)

This is wild, nice find! I see why you describe it as a rustc bug.

It would still be helpful to know the "what did the upstream crate have, and what changed to trigger the bug" though.
You've thought 1000x more about this than any of the cargo-semver-checks contributors. So things that are obvious to you are quite opaque to us, even with the playground link :/

I'd love some help from @radbuglet.bsky.social to help me understand this better. We definitely don't catch this now, but I'd like to fix that!
It'd be helpful to frame this as "here's code that existed initially, then X got added, and behold how that caused breakage."

RustConf 2026: Call for Proposals
Join us in beautiful Montréal, Canada or online for 2+ days of excellent Rust programming language content, Rust training/workshops, an "UnConference"...
⏰️ 1 day left to submit a talk!
The #rustconf program is shaped by the Rust community — and the CFP closes tomorrow @ 11:59pm PST.
If you’ve been building, experimenting, debating, or refining how Rust is used in practice, this is your chance to put that work!

Ugh, you're telling me that "great landing" and "good landing" are not `Ord`.
In retrospect this makes sense. This plane is clearly a float.

A rare case of a great landing (you can reuse the airframe after landing) that wasn't necessarily also a good landing (you can walk away from the airframe after landing).

Image from the Trail of Bits report showing the offending code associated with the second high-severity vulnerability. It includes an empty "else" branch with a "to-do" comment that reads: "TODO (eventually) reject if signature is missing"
Why was this code ever shipped?!
This is from the second vuln, where keys' signatures aren't checked before they're stored in the trusted key store.
Why would you ever ship a "TODO, actually validate signatures lol" in your secure messenger?!

Folks, there's an impersonation scam on Discord (and possibly elsewhere) that uses tech people's names and photos to slide into your DMs.
If you get a friend request / DM from "me" out of the blue:
(1) it's almost certainly not me
(2) feel free to ping me here to check!

Neat idea! Is there a way to make `cargo update` inside the project work nicely though, without updating the trip wire?
Asking because I have a weekly job to update deps, and I want to figure out how I can adopt this reasonably. Maybe have it `cargo update` then explicitly downgrade the trip wire?

And in case you missed it, here's our annual recap and our plans for 2026, which should look somewhat different than the last few years!

Yep. Only way to:
- have a dependency on Rust
- support multiple Rust versions
- retain any semblance of sanity for me

It'll be a runtime dependency!

Funny, that's also how to build cargo-semver-checks too.
Mastering that one technique seems to cover a lot of cases.

Rust's standard library on the GPU
GPU code can now use Rust's standard library. We share the implementation approach and what this unlocks for GPU programming.
We are excited to announce that we can successfully use Rust's standard library from the GPU. This has never been done before.
www.vectorware.com/blog/rust-st...
Supporting Rust's standard library enables existing Rust code to work on the GPU and makes GPU programming feel normal.

This is part of how cargo-semver-checks has been growing so quickly.
It's a lot of work to discover and formulate SemVer rules. It's fairly trivial for an LLM to take those detailed notes and write *deterministic* queries in the Trustfall query language, and back them up with tests.

I built but never open-sourced a Python equivalent of cargo-semver-checks too. What held me back was feeling like there was no funding interest for it, and that I wouldn't have cycles or willpower to maintain it in such an environment.
What you describe doesn't seem like a big stretch from there

This is the same tech that backs cargo-semver-checks. It isn't specific to Rust or Python or any other fixed set of data sources or languages.

How to Query (Almost) Everything
Never debugging the same problem twice, thanks to cross-dataset queries with the Trustfall query engine
Curious about your use case!
I've built something not that dissimilar to what you're describing, and would be happy to chat about it more if useful:
