Tech: Links for 3rd December, 2019

  1. “Both Starship and Starlink are transformative technology being built before our very eyes, here, in our lifetimes. If I live long enough my grandchildren will be more flabbergasted that I’m older than Starlink than that I’m older than cell phones (museum pieces) or the public internet itself.”
    ..
    ..
    A fascinating write-up on Starlink: its economics, its pricing, its upsides, its downsides, and the underlying strategy. A very long read, and I’ll admit I didn’t get all of it – but rewarding nonetheless.

  2. “To finish this post, I’m going to revisit its starting point. Starship is still seen by many in the space media community as a slightly overgrown version of any other rocket, with reusability tacked on. This is an error of analogy. Starship fundamentally changes our relationship with space.Starship is a devastatingly powerful space access and logistical transport mechanism that will instantly crush the relevance of every other rocket ever built.””

    And so also for Starship.

  3. “…the venture capital pouring into astrology apps will create a fortune telling system that works, because humans are predictable. As people follow the advice, the apps’ predictive powers will increase, creating an ever-tighter electronic leash. But they’ll be hugely popular – because if you sprinkle magic on top, you can sell people anything.”

  4. “But using models is inherently tricky. We can never be certain that our model behaves enough like the thing we are actually trying to understand to draw conclusions about it. Nor can we be sure that our model is similar enough in the ways that really matter. So it can be hard to know that the evidence we collect from the model is truly evidence about the thing we want to know about.”

    ..
    Evidence and proofs are very tricky to think about.

  5. “This requires more ingenuity than you might think—wires have never been perfectly transparent carriers of data; they have always degraded the information put into them. In general, this gets worse as the wire gets longer, and so as the early telegraph networks spanned greater distances, the people building them had to edge away from the seat-of-the-pants engineering practices that, applied in another field, gave us so many boiler explosions, and toward the more scientific approach that is the standard of practice today.”

    The very first link above includes a link to this gem of an essay by Neal Stephenson. Written in 1996, it still is a great read!

Etc: Links for 5th July, 2019

  1. “…in the series, Valery Legasov (Jared Harris), a member of the Academy of Sciences, lives in nearly the same kind of squalor as a fireman in the Ukrainian town of Pripyat. In fact, Legasov would have lived in an entirely different kind of squalor than the fireman did.”

    ..
    This is one of many, of course, but that line above was particularly illuminating. A review of the excellent series, Chernobyl.

    ..
  2. “The productivity equation is a non-linear one, in other words. This accounts for why I am a bad correspondent and why I very rarely accept speaking engagements. If I organize my life in such a way that I get lots of long, consecutive, uninterrupted time-chunks, I can write novels. But as those chunks get separated and fragmented, my productivity as a novelist drops spectacularly. What replaces it? Instead of a novel that will be around for a long time, and that will, with luck, be read by many people, there is a bunch of e-mail messages that I have sent out to individual persons, and a few speeches given at various conferences.”

    Neal Stephenson (whose books are excellent, and uniformly so) on productivity.

  3. “Thanos, observing that there were too many people, decided to kill half of them. But this is curiously short-sighted for a man regarded by many as a policy prophet. Any exponential population growth process will soon replace the lost people: that is why exponential growth is such a headache in the first place. For example, if an economy’s resource footprint grows exponentially at a rate of 7 per cent, it doubles in just ten years — meaning that in less time than has elapsed since the first Iron Man movie, we could be back where we started.The only lasting solution is an economy that uses resources at a sustainable rate. Malthus’s qualms notwithstanding, contraception has been a very good start. The world population growth rate is steadily approaching a very sustainable-sounding zero.”

    Tim Harford analyzes Thanos like only an economist can.

  4. “Imagine you’re cooking a roast dinner for your family of four. You opt for beef with all the trimmings, safe in the knowledge that it’s a firm family favourite. But just as you’re about to serve up, your daughter announces she’s vegetarian, your partner texts to say they’re running late, and your son tells you he’s invited “a few” friends over for dinner too. Then, your dog runs off with the joint of beef while you’re desperately trying to work out how you are going to meet the needs of all these (quite frankly) very demanding and unruly individuals.”
    ..
    ..
    The BBC on the problem of dynamic resource allocation. The excerpt, by the way, has nothing to do with the rest of the article.

  5. “Because at the end of their pilgrimage, the weary are rewarded with two things: a footbath and a bowl of steaming noodles. The footbath is just a footbath, but the noodles are extraordinary. Su filindeu is—quasi-official designation here—the rarest pasta on the planet. The dish is made specifically for this occasion; its very existence revolves around this trek. So specialized and obscure and mind-bendingly intricate is it that only a few souls can make it. And only those who reach Lula will ever try it.”

    The rarest pasta on earth. Why wouldn’t you want to read!
