    There’s a trick to using box graters that most people don’t know (I certainly didn’t until recently)

    • Lay a towel or some parchment paper in a sheet pan (optional)
    • Lay the grater on the pan
    • With your non dominant hand, hold the handle of the grater and the rim of the sheet pan
    • With your dominant hand, grate, pushing away from you + into the countertop

    The mechanics of pushing down/away are much better than holding the thing upright, dangling it over a bowl or whatever. Easy to just push with your palm too (and keep your fingers out of the way).


  • scientifically proven ecological collapse

    This is a pretty specific thing, but the general “we’re all doomed” vibe is definitely not unique to today. Boomers and older had the threat of nuclear annihilation looming over them, and before that… well, disease and famine and death and destruction due to war have historically been the norm.

    Imagine how you’d feel living in the Americas in the 16th or 17th centuries and either watching the destruction wrought by European settlers firsthand or, maybe worse, watching your peers die en masse of the diseases introduced by those settlers. Imagine living in Eurasia in the 13th century and watching the Mongol army sweep through.

    None of this is to say that today’s challenges aren’t real and serious. Just that we’re not the first to face such challenges.






  • It’s not that weird, it’s how TTLs work.

    When your computer wants to know what server x.com is, it (oversimplifying a bit) asks its own internal DNS (Domain Name System) resolver, which asks your router’s resolver, which asks your ISP’s resolver, and so on, until an authoritative resolver is found.

    Each of those resolvers, before asking the next one, has its own memory it can reference just in case it gets asked about the same address very often, because asking can be costly in terms of time (because you have to ask the next server for the answer OR because so many different request are coming in that it’s difficult to answer all of them). This memory is called a cache, and everything stored in that cache is given a Time To Live (TTL).

    When a resolver that knows the answer to “what server is x.com?” is found, it gives not only the answer, but also a guess at how long that answer is valid. That guess is the TTL for the next server’s cache. This number is controlled by the owner of x.com.

    What all this means is

    • If you expect that x.com should always resolve to the same server, the TTL should be very long (because you want the resolution to be served from the cache, meaning it’s faster)
    • If you expect that x.com will change in the near future you want the TTL to be very short (because you want resolutions to reach your authoritative server and get the new server address)

    And what THAT means, relative to this particular bit of current events, is that somebody fucked up. If this change was well-planned, then the TTLs would’ve been shortened in advance of the server switch, giving time for the downstream resolvers to clear their caches.

    But that didn’t happen, which means that when your device asks “what server is x.com?”, it sometimes gets the answer from the authoritative server (updated correctly to point to Twitter) and sometimes it gets the answer from a cache (pointed at who knows what).

    Basically, Elon once again rushed some shit through and sure enough it’s a fiasco.
