…are Turing Complete, so what you can do with them is exactly equal.
But they’re only equal in the Turing complete sense, which (iirc) says nothing about performance or timing.

Because not all humans strive for honor.
Hopefully you can publish in an open-access journal — if not it would be great if you could share an arXiv preprint :)
I hope I’m wrong! I’d definitely consider buying some — hopefully you can report back with results. If they’re slower than advertised but have the actual capacity that’d still be awesome!
This looks like it might be it:
The drive doesn’t provide 4TB of storage either, considering the single NAND chip. That means if you were to attempt to write that much data to the SSD, at some point it would either fail or start overwriting existing data.
I’d say it gets a little different with command line utilities — maybe “utility” is the appropriate term here, but I’d call something like grep
a program, not an application (again — “utility” also works).
To be sure, grep
is extremely powerful, but its scope is limited.
Physics is like sex: sure, it may give some practical results, but that’s not why we do it.

I think the same is true for a lot of folks and self hosting. Sure, having data in our own hands is great, and yes avoiding vendor lock-in is nice. But at the end of the day, it’s nice to have computers seem “fun” again.
At least, that’s my perspective.
Whatever you decide for your laptop, I’m a proponent of a barebones off-site setup if you’re trying for 3-2-1 backup or similar.
I use a raspberry pi 3 with a single HD (ZFS) retaining some number of daily/weekly/monthly snapshots. Daily rsync, everything over WireGuard+VPS (TailScale would work too).
from stdlib.h import cout
Wait this looks wrong, shit…
Anything can use it, but I think by convention it’s used for http on a non-privileged port.
Same — rsync to a pi 3 with a (single) ZFS drive at family’s house. Retain some daily/weekly/monthly snapshots.
I have a (free) VPS with static IPv4 which is how I connect everything.
Both the VPS and the remote site have limited network speed (I think 50Mbps for VPS), so the initial sync was done sneakernet (well…“airplane net”). Nightly rsync is no problem bandwidth-wise, and is mostly just any new videos I’ve uploaded to my local Immich instance.
It is “backwards” from some other commands — usually you run copy/rsync/link from source to destination, but with tar the destination (tarball) is specified before the source (directory/files).
That, and the flags not needing dashes always just throws me for a loop.
And the icing on the cake is that I don’t use tar for tarring that often, so I lose all muscle memory (untaring a tgz or tar.bz2 is frequent enough that I can usually get that right at least…).
“…and there are no comments, because it’s Self Documenting™”
Modern bots are bad, but the old school IRC (maybe early Battle.net?) bots… I’m cool making an exception for them if you are.
Fail2ban config can get fairly involved in my experience. I’m probably not doing it the right way, as I wrote a bunch of web server ban rules — anyone trying to access wpadmin gets banned, for instance (I don’t use WordPress, and if I did, it wouldn’t be accessible from my public facing reverse proxy).
I just skimmed my nginx logs and looked for anything funky and put that in a ban rule, basically.
I can only remember this because I initially didn’t learn about xargs
— so any time I need to loop over something I tend to use for var in $(cmd)
instead of cmd | xargs
. It’s more verbose but somewhat more flexible IMHO.
So I run loops a lot on the command line, not just in shell scripts.
I think mplayer
has an ASCII output mode (VLC, too?), and I believe youtube-dl
can output to stdout.
The rest is, as they say, left as an exercise to the reader.
I switched from raspberry pi and orange pi to a cheap Intel NUC, and I think it’s just a much nicer experience.
The pi is great fun, but the HW transcoding on a NUC “just works,” and the SSD and 16GB RAM opens a lot of doors. My N100 NUC was less than $150, and it included everything (case, power supply, 500GB SSD).
My pi found new life as an off-site backup: attach a big HDD, set up WireGuard, and have a cronjob do daily rsync and snapshots. I have it set up at in-laws, and it works great.
You can turn it off, at least for ext4: https://lwn.net/Articles/784041/
I think a lot of companies view their free plan as recruiting/advertising — if you use TailScale personally and have a great experience then you’ll bring in business by advocating for it at work.
Of course it could go either way, and I don’t rely on TailScale (it’s my “backup” VPN to my home network)… we’ll see, I guess.
