I don’t think Rust needs this; Rust has done great for the last decade with the coherence rules it has. I am glad to not have to worry about this, and to not have to worry about any of the downstream problems (like linker errors) that cohe

> you're arguing semantics here Yes, semantics — what do things mean, exactly? — is the subject of the discussion here and is actually quite important in general.

It’s odd that the article identifies Apple’s hardware as a limitation for AI. I don’t think this is the case. If anything it’s the opposite, and makes Apple’s lack of execution more mysterious. I was running Stable Diffusion on my iPhone tw

Rust just doesn’t really have linker errors. After 8 years of programming ~exclusively in Rust it’s easy for me to take this for granted by forgetting that linker errors even exist — until I am rudely reminded by occasional issues with C&#x

This article lists international money transfers as a non-useful application of blockchains. USDT on Tron alone is now settling 1.25T$ (1/3 of Visa’s annual settlement volume). Clearly some people do find them useful.

I haven't paid close attention recently but that doesn't seem that far off of performance available via (hardware accelerated) AES? Looking at https://eprint.iacr.org/2018/392.pdf , it seems like: - Intel CPU

A lot of discussion about async Rust assumes that the reason one would want to use async/Futures is for performance and scalability reasons. Personally, though, I would strongly prefer to use async rather than explicit threading even f

Yes, that’s exactly the issue. You trade that friction for not having the friction of type errors in queries at runtime. Whether that tradeoff is a good one depends on your situation and preferences. (You can also check in the results of th

One use case for generating group elements with verifiably unknown discrete logs is for a commitment scheme, like a Pedersen commitment. In a Pedersen commitment, you have two generators, let’s call them G_value and G_blinding. To commit t

I’m a coauthor of Ristretto. There is a much more concise explanation than in the linked post: in Ristretto, the encoding of group elements was constructed so that the encoding of the identity (zero) element of the group is the all-zero byt

by hdevalence 4y ago
It’s not strange at all. The “all zero public key” is the encoding of the zero element (identity element) of the group. Finding the private key corresponding to a public key A is finding the number a so that A = a*B. When A = 0, this is rea

Correct, there’s no actual problem here, just a potential performance pitfall, but that pitfall is no worse than a naive synchronous implementation would be. There’s no big problem here, just write code and run it. If it is a really big pro

Unfortunately for those who care about noise reduction, LL patented the design, preventing its widespread use.

I don’t know about the nature paper’s assumptions, but supercharging provides far more power than could possibly be supplied to the grid via V2G — for instance, a 100A home service can draw at most 24kW (AC), while supercharging draws up to

The 2 cent figure is per kWh, not per cycle. Multiplying by the 75kWh pack size gives $1.50. What about the remaining 10X? The calculation you’re doing isn’t the right one, because the battery wear isn’t directly related to miles driven; Te

Yes, but for this reason, the Bluetooth implementation is on physically separate, untrusted hardware that has no access to the buttons or screen other than by communication with the secure element (see [0] for the Nano X; I’m assuming the S

No, the attacker still needs physical access to the device, because signing requires on-device approval. The security model already assumes that the entity requesting authorization is untrusted, so the security model is basically unchanged.

by hdevalence 4y ago
If your secure hardware doesn’t have a display, how do you know what you’re signing? You can’t, so you’re forced to trust that the software talking to the HSM isn’t lying to you about what data it’s asking to be signed, and at that point yo
