  • Prescriptive vs. descriptive is different in colloquial language than in science.

    If my data logger captures 1kB/km, how many bytes/meter is that? In every other quantitative unit I can think of, the k should cancel out; but if you want computers to be special, that’s your preference.

    Metric sucks. Powers of ten are arbitrary, a fluke of biology. Powers of two are the only sensible way to make a system of measurements.

    Then why are you trying to shoehorn binary into decimal? As in: why are you using decimal prefixes in the first place? Answer is probably that most people have intuition behind powers of ten. You can easily express in log2-bytes instead (a GiB is 30, a TiB is 33…etc.). Be the change you want to see!

    I’m born and raised in the USA, and while imperial units can be handy for a few every day tasks, there’s a reason why the sciences in the US tend to use metric.

    Regarding cooking, I’ll stick to metric, measured by weight. I can double, halve, or multiply my recipe by pi, and all I have to do is look for a different number on my scale.



  • Giga, Mega, Kilo…these are all SI prefixes; they differ by a factor of one thousand, which is very clean in base ten.

    Ten in binary systems isn’t special, but two is; and two to the ten is very nearly a thousand, and a thousand separates the major SI prefixes. This is a neat coincidence, but should not IMHO change the meaning of the prefix.

    Metric units are awesome in large part because of the use of prefixes; messing up the meaning of prefixes is a disservice to the SI/metric system. Giga == billion independent of the context. A light-year is close to 10 petameters, but no one would claim it’s exactly 10Pm.

    Now, if you want to call it an “imperial gigabyte,” by all means…



  • If you want a non-hazardous (to humans) degreaser, d-limonene can be purchased food grade. It’s just orange oil, has similar properties to kerosene, but is “generally recognized as safe” by the FDA and EFSA. Commonly found in liquid hand soap.

    Basically, it’s paint thinner you can drink.

    It can also be used as an additive in petroleum based cleaners, in which case, definitely not a good idea to drink!

    More to your question, I usually start with hot soapy water as a first pass, but it probably won’t get your chain looking like new–need the degreasers for that.







  • Though, technically that leaves you more at risk of ransomeware or something that overwrites your data.

    I rsync as well, but use snapshotting on the remote drives. So, a bad rsync would suck but shouldn’t really result in data loss. Ransomware on my local+remote server would of course be very bad…


  • I do something similar — I have a raspberry pi and a HD, with daily rsync and snapshots (monthly retained indefinitely, weekly retained for a month, daily retained for a week). It’s at family’s house, connected to my home via WireGuard via a VPS. Tailscale (or anything really) would also work here.

    It’s a great setup! Just have some watchdog reboot if it can’t talk to home (a simple cronjob with ping -c1 home.lan || reboot or similar).

    Even our “slow” 35Mbps upload speed is way more than enough for incremental rsyncs of my Immich library. The initial sync was done in person, though.
