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

qjkxbmwvz@startrek.websitetoPolitical Memes@lemmy.world•Goo Goo Gaga! Breaking News: Sensitive Stephen can dish it out but can't take it.5·1 day agoWhen I criticize my baby, he looks me in the eyes and asserts dominance with a “what you gonna do about it?” shit grin.
Comparing him to Stephen Miller is just offensive.

qjkxbmwvz@startrek.websiteto Dad Jokes@lemmy.world•I started a band called 999 megabytes...English4·2 days agoPrescriptive 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.

My favorite is habanero — there’s no ñ, just n, but some will make a show of pronouncing it with the incorrect ñ sound.
qjkxbmwvz@startrek.websiteto Dad Jokes@lemmy.world•I started a band called 999 megabytes...English42·2 days agoGiga, 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…
qjkxbmwvz@startrek.websiteto bike wrench@lemmy.world•How do you clean a chain that has chunky grease/dirt buildup?5·3 days agoThe crazy thing is, d-limonene can be used as a paint thinner, you can burn it in a diesel or a jet engine, and when ingested it can reduce heartburn.
qjkxbmwvz@startrek.websiteto bike wrench@lemmy.world•How do you clean a chain that has chunky grease/dirt buildup?9·3 days agoIf 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.
Far right leaders in power? Simple, just reverse polarity!
qjkxbmwvz@startrek.websiteto Selfhosted@lemmy.world•FFS Plex, the server is on my local networkEnglish2·6 days agoFrigate is pretty good, too. I’ve only been running it for a few months but I’m very happy with it.
qjkxbmwvz@startrek.websiteto Today I Learned@lemmy.world•TIL I learned a I have a mental disorder; therefore I am qualified for a COVID vaccineEnglish24·7 days agoI’m in California, but we still (currently) have the same federal bullshit requirements. Doctor friend said I should lie.
Made an appointment, and the pharmacist asked if I was immunocompromised, or XYZ, and I just told them that I qualify—no follow up questions, just a jab in the arm.
To be fair, I do have anxiety that my government is trying to kill me, but that’s just crazy…
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

work as advertised for me, but I’m running headless homelab servers and a laptop withi3
. Maybe DEs/GUI shutdown is more subtle?
Yeah, I run
i3
and headless servers, so it’spoweroff
orreboot
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.
I think parent’s comment (no pun intended) is that if you want to, all things being equal, but you don’t solely because of money, then that’s a sad statement about the state of the world, not about you as a person.
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.
