Do people realize that Keccak replaces a lot of complexity and offers powerful composable primitive already? Instead of saying "blake is faster, but sha3 is standard", pick SHAKE-128 and build everything with it: hash, MAC, symmet

As a wise programmer once said: "Lisps are created by those who are lazy to write proper parsers" Homoiconicity does not mean your syntax should be backwards. Look at Io language: it is basically a Lisp, but it has parens in the f

Certificates just add more keys to worry about. The beauty of SSH is that it does not add hugely trusted parties in the name of convenience, while the UX of TOFU (trust on first use) is pretty decent. The real solution to break out of these

That was a new spin to the explanation that I didn't think of before.

Strongly disagree. I am the person who hates C/C++ and likes languages like Ruby. I like Rust specifically for the reason that I don't have to learn C++ like "grown ups" and can write my crypto libraries in something muc

No it is not. The whole point of GC is to collect cycles and not think about ownership, while Swift and Rust require you to think about ownership. In Rust you do so via borrow checker or explicit Rc/Weak wrappers. In Swift you do that

Ristretto is a restricted form of Decaf, that is, specific to curve25519 and deals with a sign choice, while Decaf is generic for all cofactor-4 Edwards curves. In other words, the joke around coffee takes a 90º turn with Ristretto because

Math is about precision, so it's generally not a good idea to have something become "more 0" than actually needed. Especially in cryptography. So here's my advice. If you multiplied too much by zero, you can make it less

Ristretto is not a curve, it's a group. Curve25519 is a _curve_ that implements a non-prime order _group_. Ristretto255 is a prime-order _group_ that uses Curve25519 as an underlying _curve_. In other words, Ristretto is a pair of enco

What is being meant (i presume) is that even if you are a developer of those repos, do not edit them within the host repo. Work on them separately, as if you were an independent developer, and then bump their revision as a submodule - the s

This is not a problem with splice per se, this is N+1 problem with treating network as "file socket" per Unix classic idea "everything is a file". It is crazy to consider that writing to a TCP socket over wifi with 1001

OTOH, was there really a time when humans were not enslaving each other in any form? I don't mean in a wide marxist term like "wage slave", but more specific kinds of bonding and control. Liberal changes in Europe in end of 1

The point of the OP was that Dalek library provides API to Ristretto ( https://ristretto.group ) which is a proper mathematical prime order group, unlike stock Ed25519 API that exposes cofactors and caused famous issues in Monero.

HTTP/2 is more like a transport envelope around HTTP/1, the goal of http/2 was to optimize transmission and avoid breaking http/1 semantics for servers and clients.

Bitcoin is quite literally a religion. It has dogmas ("not your keys, not your coins"), traditional values ("21 mil"), a prophet (satoshi), celebrated dates (Jan 3). On the serious side, Bitcoin is all about "let&#x

Barcelona’s blocks turn out to be not so cute. Traversing multiple blocks straight requires diagonal zig-zags eating 10% of time and you could easily lose orientation, especially if you jump into a shop on the corner. Also it’s simply annoy

I learned Rust because I need to write low-level high-performance stuff and I don't want to spend time learning how to do it correctly in C++. Rust compiler automates many chores for me, just like any computer technology is supposed to

>In fact, you would not have to implement any function; you’re just write its name, and the compiler would implement it for you. Isn't this equivalent to placing the function code into its name, in other words, inlining the function

I understand and even share a little bit of your sentiment, but I'm tired of stretched "X is now not what X was supposed to be". Strictly speaking, the Internet was supposed to help some servers survive and continue working t

You are right, that's not a technical problem and Bitcoin is not a technical solution either — that's a social game of "let's make ourselves some new money without built-in constraints". Then you would need to add s

That's a false dichotomy. Anyone would choose someone they trust most out of other need-to-trust counterparties. If there was an alternative to not use any unnecessary counterparty at all - that would be even better. E.g. if you transf

You understand that "taxes you owe" are defined as an optimization function (Laffer curve), not some kind of moral imperative? By the very definition of the process you cannot possibly "owe" these taxes.

LOL, but no. What they probably mean is that they have a transaction that consumes $1000000 on their address and creates two outputs: $100 withdrawal for client A, and $999900 on a "change" output. Later withdrawals have to link t

Why for free? Give, like, a 50% discount. Their "free stuff" would be "50% for free".
