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.
…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.
Yep, you’re right — I was just responding to parent’s comment about fiber being best because nothing is faster than light :)
That’s…not really a cogent argument.
Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).
Light in a fiber travels much more slowly than in vacuum — light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they’re just a) not in free space and b) generally not optical frequency, so we don’t call them light, but they are still governed by the same equations and limitations.
If you want to get signals from point A to point B fastest (lowest latency), you don’t use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/
Finally, the reason fiber is so good is complicated, but has to do with the fact that “physics bandwidth” tends to care about fractional bandwidth (“delta frequency divided by frequency”), whereas “information bandwidth” cares about absolute bandwidth (“delta frequency”), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz — so a tiny fractional bandwidth is a huge absolute bandwidth.
80% of the USA lives within urban areas (source). Urban “fiberization” is absolutely within reach.
Agree that running fiber out to very remote areas is tricky, but even then it’s probably not prohibitive for all but the most remote locations.
So the irony is
I see what you did there…
I think you mean more scrupulous, not less.
Hopefully you can publish in an open-access journal — if not it would be great if you could share an arXiv preprint :)
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.
Hah not at all! I need to remind myself to hydrate and fuel constantly if I’m doing any sort of exercise.
If you’re exercising and you drink because you’re thirsty, you probably waited too long to hydrate.

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).
Others mentioned virtualization — I have had issues with COW filesystems (btrfs), as COW does not always play nicely with VM drives (extreme fragmentation and very poor performance).
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.
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…).
You mentioned ham radio — definitely fun! It’s a process to get into it though, as you need to study/pass an exam, and then you need a radio. Radios range from cheap ($25 or so) in the VHF/UHF (“walkie talkie”-style) to more expensive for an HF rig ($1000 range for 100W HF). If you want to get into low power (“QRP”) it can be much cheaper. You also need a fair amount of space for a good antenna setup…
There are tons of different communication modes, some without a computer and, like you mentioned, some that use computers. wsjtx and fldigi are popular programs.
Good luck!
Maybe a dumb take, but I think milking customers for all they’re worth is much better option than what HP is seemingly doing — which is milking them for all they’re worth this quarter.
Like, there are companies with a cult like following (Valve comes to mind) and while they could probably increase profit for a quarter or two, they seem to be playing the long game fairly well. Which is ultimately better for everyone — they get more money over your lifetime, and you get a product that you’re happy with.
I’ve been happy with the SMLIGHT SLZB-06M. You can easily flash firmware, and it has PoE which was important for me. I believe it also supports Thread, but I haven’t tried this yet (and I’m not sure if it supports it at the same time as Zigbee).
Zigbee smart plugs from Third Reality have been pretty solid in my experience, and they report power usage.
For circuit breaker level monitoring, I have an Emporia Vue2. I have it running esphome, completely local — unfortunately this requires some simple soldering and flashing, so it’s not turnkey. But it’s been rock solid ever since flashing it. (Process is well documented online.)
I’ve had decent luck with cheap wifi Matter bulbs, but provisioning them is finicky, and sometimes they just crap out and need to be power cycled; Zigbee bulbs (e.g., Ikea) have generally been reliable, though sometimes I’ve had difficulty pairing them initially. After power cycling a Matter WiFi bulb, it takes a while for it to respond to Home Assistant; Zigbee bulbs generally respond as soon as you power them on.
I have a wired smart light switch from TP-Link/Kasa (KS205), and it’s been completely hassle free (and totally local — Matter over wifi). The Kasa smart switch dongles I have work flawlessly but need proprietary pairing, and I’m afraid to update firmware in case they lose local support.
Good luck! Fun adventure :)
