    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.











  • Yes, true of most any national/international chain.

    It’s because they value large volume, year round availability, and high consistency from their beans and roasts, so that no matter what location you go to it tastes exactly the same.

    To do that, they select and blend several bland varieties of coffee bean, put them through an aggressive industrial cleaning and drying (which reduces the natural fruity and funky flavors but minimizes costs) then roast them in huge batches to several steps past where a normal roaster would stop for a given roast (a darker roast gets rid of more of the unique flavors of the coffee cherry and brings out more uniform roast flavors instead).

    Again, not something exclusive to Starbucks at all, and plenty of small coffee shops don’t bother with the hassle and just buy cheap bulk coffee pre-roasted by large scale operations and will have similar results.

    But man, when you get coffee made in small batches, with natural processing or even fermentation and gently roasted… It’s an entirely different experience.
