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 :)

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.

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.

Hobby 1: Ballroom dancing

No I’m pretty sure Strictly Ballroom is a completely accurate portrayal of ballroom dancing.

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).

I think some commercial TVs might do what you want.

In grad school I picked up a an old free HP LaserJet, with an Ethernet NIC card (it was an upgradable printer, maybe from the mid 2000s?).

It was great! Only complaint was no duplexer, but the thing printed great from Linux and the generic toner was cheap.

Today though…the experience is a bit different.

Yes. But why is there an absence of light?

If there are infinite stars, then every direction you look would encounter a star. (Things stay the same brightness per subtended angle as they get far away. Space dust doesn’t matter, as it would thermalize and radiate.)

So, the universe can’t have infinite luminous matter, be static and ageless, because if it were then the night sky would look like the surface of a sun.

This may all seem obvious, but it’s neat that you can figure that out with the naked eye.

https://en.m.wikipedia.org/wiki/Olbers's_paradox

Olbers’s paradox, also known as the dark night paradox or Olbers and Cheseaux’s paradox, is an argument in astrophysics and physical cosmology that says the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe.

The night sky being dark has some profound cosmological implications.

Widely regarded as the best Seinfeld episode is The Contest. It’s about who can go the longest without masturbating, but what makes it great is that they never say that explicitly — it’s just euphemisms and insinuation. And it’s hilarious IMHO.

I believe they initially wanted to spell it out, but the networks wouldn’t let them (I could be wrong). Definitely for the better that they danced around the topic the way they did.

(Yes I know, Jerry Seinfeld is a problematic person, I’m just trying to answer the question…)

Here’s January of this year. San Francisco, so pretty moderate weather — typically don’t run heat during the day, and low 60s at night (if at all) during the winter. Large temperature gradient throughout house, typically.

South facing windows gives kitchen and living room a greenhouse effect, particularly in the winter, hence the large daily temperature swings:

Good point — it is “incrementally free,” although I guess if you count tire wear and tear that’s not even true.

You’re just gatekeeping.

ThinkPad with a generator? Nothing wrong with that — maybe add LoRa, get a ham license and add some packet radio or digital modes and you have a neat disaster setup.

MacBook that you don’t want to scuff? Well, I’m not that precious with my gear, but you do you. Many Mac laptops last a very long time, and the performance of modern Apple silicon is really, really impressive — and you have UNIX out of the box. Plenty for a tech enthusiast to like.

A lot of non-graphical utilities — basically the *NIX coreutils, plus stuff like rsync, ssh, compression/archival tools (tar, gzip, bzip2, etc.), grep, and the like. Git also comes to mind.

I think part of this is that the UNIX philosophy is “developer friendly” — tell a good dev they need to make a compression utility that follows this protocol, and they will make a compression utility that follows the protocol.

Your local city college may or may not offer free classes (in San Francisco, you just need to show proof that you live in the city with some legal status).

Some public transportation is free for certain groups (youth and folks experiencing homelessness can get free passes here).

“First X of the month” at the zoo/a museum/whatever — lots of venues have free events.

A jog, bike ride, hike — lots of great stuff outside!
