UB can lead to memory safety issues[0], among other terrible outcomes. Hence it’s worse than memory safety issues. 0: https://lwn.net/Articles/342330/

It's worse than a memory safety issue, it's undefined behaviour (at least in C, C++, and Rust)

The problems Rust are trying to solve are both novel and difficult so it isn't particularly surprising that it's taking time. The team has also landed great improvements, like NLL. I'm optimistic about the direction of this,

You aren't really contradicting me, I agree that Rust isn't a great language for prototyping. However, there are some solutions that help with prototyping, namely: judicious use of Clone‚ Arc, Rc, and unsafe. In particular, if you

Yes of course, although, as I said in a sibling comment, it's a bit convoluted as an example. The fundamental problem is that the xor mutable and shared reference rule gets in your way when you access separate fields through &self

Which statement and why? The code is obviously stupid and convoluted because I threw it together in a minute to illustrate a point.

Not Python because getting Python to run on different machines is an absolute pain. Not Go because of its anaemic type system.

I mostly don't agree with this take. A couple of my quibbles: "Cognitive overhead: You’re constantly thinking about lifetimes, ownership, and borrow scopes, even for simple tasks. A small CLI like my notes tool suddenly feels like

I agree the UX challenge is much more challenging for decentralised services. I don't know enough about Bluesky to really comment on whether it is centralised or not. Regardless, I think there's another thing that helped Bluesky:

This is, at least in part, a UX problem. Even as someone with a lot of technical experience I found Mastodon quite disorienting at first. Bluesky has solved this much better which is why they've won out over Mastodon.

The core tenets of web3; privacy, data sovereignty, encryption, open source, open protocols, and peer-to-peer networking are all good. The problem is the movement was never truly about this, and, even to the degree it was, it was taken over

I agree with the idea of not making bugs in the first place. Overall I think this piece is great and includes good suggestions. However, personally I think the best weapon to avoid writing bugs is making them impossible in the first place,

I find the author's description of hardware design, of which I know very little, to match how static typing work. You are explicit about the interface in order to compose while treating individual parts like black boxes. On static type

I'm inclined to share your scepticism on carbon credits, but a carbon tax is very efficient. It simply prices in a negative externality and lets the market solve the problem. This is probably why it's one of the few taxes that has

Certainly and that speaks to the problems of democracies. At least in theory if you ensure the tax is progressive as I suggested it shouldn't make the life of the majority unaffordable. However, monied interest would of course try, and

I didn't mean to imply communist dictatorships always get this right, of course even with central planning and, supposed, long term thinking it has gone horribly wrong before, as you point out. It does make me think about the failure t

by K0nserv 1y ago
The US, like most democracies, is worse at long term planning. It needs robust incentives to counteract short term instincts. A $100/ton carbon tax would raise $490b(based on 4.9 billion tons of co2 emissions[0]) per year that could be

Fossil fuels aren't just bad for global climate, air pollution (which is mostly local) kills 7-8 million people per year. There's an interesting study that arises from a natural experiment based on coal subsidies in China[0]. It f

Yes, but did you buy a general purpose computer? I don’t think smart phones were ever marketed that way. Now, if you want to install Linux on that hardware you should be allowed to do so.

Yes! I'm a little biased as someone who worked briefly on CocoaPods, but it was an indispensable tool for many years. This is evident by its massive popularity. Like with NPM, many people ran into issues ultimately rooted in not unders

Op here: The point I'm trying to make in the piece is that this is less authoritarian than the common suggestion that Apple and Google be forced to change how iOS and Android works. The piece is meant to be a juxtaposition to that idea

The facts that Send/Sync bounds model are still relevant in all the other languages, the absence of Send/Sync just means it's easier to write subtly incorrect code.

Haha, yes! I'm only vaguely familiar with 40k, but LLM prompt engineering has strong "Praying to the machine gods" / tech-priest vibes.

That's it. The attack is very clever because it abuses how downscaling algorithms work to hide the text from the human operator. Depending on how the system works the "hiding from human operator" step is optional. LLMs fundam

The security endgame of LLMs terrifies me. We've designed a system that only supports in-band signalling, undoing hard learned lessons from prior system design. There are ampleattack vectors ranging from just inserting visible instruct

Yes I've seen issues with both, but in part what's tricky about false negatives is also that you don't necessarily realise they are there. In the systems I've worked on we've made it simple for operators to verify t
