In grad school I bought a blue (405nm) laser pointer. It was supposed to be <5mW, but I measured it at over 70mW.

I think “boring” (making a hole with a revolving but) in the title is a pun on this…
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…
Frigate is pretty good, too. I’ve only been running it for a few months but I’m very happy with it.
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.
I got one from goHardDrive on eBay (link). It was cheap enough, looks flawless, and knock on wood has been working fine.
Googling around, the brand gets…mixed reviews. My use case is such that of this drive fails it’s not a big deal.
poweroff
and reboot
work as advertised for me, but I’m running headless homelab servers and a laptop with i3
. Maybe DEs/GUI shutdown is more subtle?
Yeah, I run i3
and headless servers, so it’s poweroff
or reboot
for me. Always works as advertised.
Except on the Linux systems I’ve used, when I ask it to shut down, it shuts down no matter what. Windows and macOS let programs stop the shutdown process indefinitely (when shutdown/reboot are invoked the usual way).
I think that’s what the meme is trying to get at.
Never said that at all. I’ve had some fantastic food in England.
Oh please. The US has many problems, and there are food deserts to be sure — but go to a first class US city and you’ll find great food.
I’ve honestly never understood people who feel the need to “replace” Spotify. … Spotify has never made sense for my use-case.
I don’t know how to say this, but…you have extremely uncommon use-cases:
…during those times, my phone is either fully turned off (so I’ll use an MP3 player), or it’s in Airplane Mode.
Many people listen to music on stereos and don’t necessarily want a device plugged in, so
I just download the music I like to my device and listen to it via VLC.
either doesn’t work or is substantially less convenient than e.g. casting from a phone.
Not hating on your setup at all, but it’s very niche, in my experience.

Atomicity (something happens in its entirety or not at all), consistency (database is always in a valid state — if the database has constraints, they will always be honored), isolation (transactions don’t step on each other), durability (complete transaction is complete even if there’s a power failure).
Not a database expert, my parenthetical explanations may need work.
Some would call the former command cat abuse.
In short, unless you want the contents of a file printed to stdout (or multiple files concatenated), the command can probably be written without cat
, instead using the filename as an argument (grep pattern file
) or IO redirection (cmd < file
).
Stylistics and readability are another thing though.
scolding hot metal
I like the mental imagery — it’s not scalding hot, no, the metal is actively chastising you.

I have some bad new for you about Linux…
If you’re running it via docker compose it’s trivial to upgrade, and there are no breaking changes. Pull, down, up, you’re done.
