ZigBee router thing:

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 :)

My recollection is that the DVD included that library, but it’s been a while…

Most Linux filesystems, being case sensitive, won’t find the SUDO command.

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.

Would that really help though? Gold is super soft so I think it would need to get frequently coated/plated again — and we already have pretty good and resistant marine paint.

Titanium is very corrosion resistant, not to mention plastics/fiberglass/carbon fiber, as I understand.

But yeah, cheap gold would be be great, just seems to me that the market would more be in e.g. electronics, where both corrosion resistance and electrical conductivity are required (something gold is fairly unique at).

Yep, you’re right — I was just responding to parent’s comment about fiber being best because nothing is faster than light :)

Can you explain the Ethernet requirement more? Was that just that the computer didn’t have WiFi, or was it set up such that only the wired interface worked with their VPN, or…?

Can you explain your travel router situation? Did you use the travel router to access WiFi and provide an Ethernet port for the computer (I think this is called “WISP mode”)? Or was this an 4G/5G router?

In any event, at least on Android you can connect to WiFi and tether to a computer over USB. It’s very useful for setting up a computer without WiFi drivers, as Linux will almost always recognize the shared Internet (so, it’s functionally a USB wifi dongle with very good driver support).

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 :)

Bonus points: use non-qwerty keyboard for added obfuscation (but keep the qwerty key caps of course).

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.

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.

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.

What strings are you referencing here? Is the financial counseling mandatory?

Not everyone is eligible for this, but that’s kind of a different issue.

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).
