    No idea how I’m supposed to take this ranty blog needlessly interspersed with furry cartoons seriously. But it’s basically just restating (poorly) all the same criticisms and alternatives written about here: https://www.latacora.com/blog/2019/07/16/the-pgp-problem/

    The ‘real’ criticisms of PGP are that it’s old, it’s clunky, and it doesn’t support forward secrecy by design. None of that is invalid, but I think the importance of those points depends on the use case and user.

    The alternatives given are myriad and complexity and clunkiness are interspersed between dozens of solutions instead of well understood and documented in one tool.

    That isn’t a superior approach. I’m not arguing that PGP is perfect, but it’s absolutely asinine to suggest (like this blog and others suggest) that the solution is to use dozens of other solutions with their own problems and with less auditing.

    If we’re going to replace PGP, we need to do it properly in a centralized library/toolchain. Breaking up the solution and spreading it around just magnifies the problems.

    Different caller, same question.

    The BSDs I’ve used are extremely well documented and cohesive. No basic tools or functions are missing and everything works very simply and together as a whole. The tooling they put forward in the 2000s like DTrace, ZFS, jails, bhyve, were simply unmatched for their capabilities at the time. Having all those tools on a simple and fast OS at the time felt like living in the future.

    At the same time, BSD is severely lacking in gaming, graphics performance, compatibility with modern ecosystems, ease of use for less technical users, and generally seems to have stagnated in the last 10-15 or so years. Some chalk that up to leadership, some to the license / corporate interests largely moving to Linux, who knows. But these days I use Linux and while I miss the halcyon days of BSD, I wouldn’t switch back.




  • Entangled particles cannot transmit information between the pairs. That would violate information theory and likely causality as well.

    Quantum networking is instead focused on using extremely robust encryption that can detect interception using entangled pairs of light particles being transmitted together in the fiber optics.

    Edit:

    To elaborate on this, let’s talk about how entanglement works.

    Let’s say I have two identical bags. Into each of the bags I put one of two balls, one colored red, the other blue. I then mix these bags up like a shell game and hand you one.

    Now you can travel anywhere in the universe, and when you open your bag, you know exactly what color you have and what color I have too. No information transmitted, only information inferred.

    Now the quantum part is tricky. Basically when you do this experiment with quantum particles, for example generating two particles, one that must be spun up, the other that must be spin down, there’s a lot of science that “proves” the particles spins are each entirely random, implying that somehow when you examine one you force BOTH particles to pick their opposite spins instantaneously across any distance.

    Now there are two major explanations for how truly random gets ‘picked’ by the universe.

    The first one is Bell’s theorem, or ‘spooky action at a distance’, basically claiming that until you ‘observe’ the particles they both exist in an undetermined state, neither spin up or down, and when you look, the universe forces things to get corrected through some mechanism we don’t understand. Scientists generally prefer this theory because the math is clean and beautiful, and randomness written into the most fundamental levels of the universe fits philosophical ideals nicely (more on that in a minute).

    The primary alternative theory is much more mundane, but has huge implications. Basically this theory, called super determinism, claims there is no such thing as true random, and instead the universe has a set of hidden variables determined from the very beginning of the universe. This implies that time is an illusion and everything is fully deterministic across the entire universe. Scientists generally hate this theory because the math is much harder and uglier, and some interpret this to mean there is no free will.
