I don't think Rust vs. Zig has anything to do with why people are talking about this. It is a large piece of "real software" that underwent a full language transition in ~1 week using LLMs. That is a big deal regardless of the language and will be a case study regardless of how it turns out.

> On the other hand, Rust is a complex language prone to refactoring avalanches, where a small change in a component forces refactoring distant code.

Are you saying this out of personal experience or just hypothesizing? I am working on a large, complex rust project with Claude Code and do not experience this at all.

The most common reason is that a quick manual step is needed before publishing. Nothing malicious. Often it is just removing paths used during dev from Cargo.toml. Should it be automated? Sure, but that is extra work.

I agree that position is nonesense. I mean, the single best defense against supply chain attacks is to bring everything in house. Is that reasonable? No…

New comment by carllerche in "GitHub should charge everyone $1 more per month to fund open source"

carllerche — Wed, 14 Jan 2026 18:27:30 +0000

Help normalize saying no? As an OSS maintainer, the sense of entitlement many have is quite frustrating. After years in OSS, I have built up a thick skin and am fine saying no, but many aren't.

I 100% agree with this. It also is 100% OK to fork aggressively and patch yourself.

You are very confidently incorrect. So incorrect, it is hard to even start correcting you.

* Inflation is not caused by "putting your money somewhere" What on earth. * At a high level, inflation is caused by either "too much money chasing too few goods" and/or the cost of producing the goods rising. Money supply can increase without causing inflation if the supply of goods can also increase. In short, the supply of money can increase without causing inflation if productivity rises to match it. * Most people do not "put money" in loans what are you even talking about there? * Bank loans do not automatically increase the supply of money. When a loan is taken out, it is (mostly) deposited to another bank, resulting in a net-zero change in money. Increasing the supply of money requires the federal reserve to take steps.

I doubt it. Eating healthy is already cheap and easy (rice & legumes as a base, fresh or frozen veggies based on what is cheapest at the time). It just doesn’t taste as good and gets boring fast.

I respect that some prefer just to use SQL, but that isn't where most stand.

Also, instead of a reactionary "all ORMs are trash," where ORM probably means different things to different people, maybe you could provide some value to the conversation by providing specific points and/or arguments supporting your feelings about ORMs. At the very least, you could provide some citation to an article that does the summarization.

IMO corporate ownership isn't bad as corporations rent housing to individuals who can't afford mortgages. Let's say corporations are 100% banned from the housing market. 85% of Americans cannot qualify for a mortgage, where would they live?

Good thing this would have no impact on home values. Hedge funds getting involved is a symptom, not a cause. Hedge funds buy properties *because* home values go up due to limited supply. The only thing that can lower housing prices is a dramatic increase in supply.

The issue here is that, after M110, there is little the police can do to prevent *public* usage of hard drugs like fentanyl. Drug addicts will be smoking fent in front of a K-5 school and all the police can do is fine them. There is more enforcement of public alcohol consumption than fent / meth.

It isn't a question of backwards compatibility, it is just way easier to iterate / evolve in a crate than it is in stdlib.

For example, Tokio has the concept of "unstable" features, which have stronger stability guarantees than Rust nightly. First, you can use them with the stable rust compiler, second we guarantee that unstable features will not break across patch releases. This may seem small, but it lets us experiment with new functionality and get real world usage. Many of our users cannot use Rust nightly but can use Tokio unstable features.

carllerche — Sat, 16 Jul 2022 23:36:53 +0000

Can you elaborate on "heavy weight"? Tokio lets you opt-in to only what you need via feature flags. This lets you use a small subset of the lines of code & transitive deps.

Here is the PR: https://github.com/rust-lang/futures-rs/pull/2551

Yield = wake the `waker_ref`. Avoiding the yield would be clone().wake().

That said, "poll immediately" isn't actually a thing nor was it ever a thing except in incorrect implementations.

It wouldn’t be too hard. The trickiest bit would be putting together a consistent API.
