Slack got me through college on an ancient (even at the time) ThinkPad 600e. Good times!

I had a suite of scripts to log in to the university Linux cluster, download the kernel source and out-of-tree modules (required for the PCMCIA WiFi adapter), compile it, and rsync it back to my laptop.

I’m a ~/tmp man myself.

Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

It’s a fun exercise, not sure I implemented it in a smart way, but it works :)

I would recommend PoE security cameras. You probably want support for RTSP / ONVIF.

I have some Amcrest cameras talking to Frigate. It is completely local—cameras on a separate VLAN that can’t talk to the Internet, footage is recorded on a server running Frigate. Works very well for me. No vendor lock-in is also nice!

640k 780k ought to be enough for anybody…

Not sure I agree.

First, stocks tend to be highly correlated with “the market” (see financial “β”/“beta coefficient”). For example, look at, say, The Home Depot or Ford Motors. From January 2000 to January 2003 (spanning the dot com bubble) they each lost about a third of their value, yet these are not “dot com”-centric companies.

Second, the promise of AI is that it will help every company that has desk jobs. So every company has this expectation now priced into their stock, and if the bottom falls out, well…

Not an analyst/I don’t pick stocks, but just my 2¢.

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.

Frigate is pretty good, too. I’ve only been running it for a few months but I’m very happy with it.

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.

Linux distros can still do…questionable things. In grad school I tried Arch for a bit, and I once was late to a video call because I had updated my kernel but did not reboot. Arch decided that because there was a new kernel installed, I didn’t need the modules for the old — but currently running! — kernel, so it removed them. So when I plugged in a webcam, the webcam module was nowhere to be found.

But yeah…somehow, still not as bad as Windows updates.

Our Internet went out for a few hours today, so naturally my smart switches, lights, cameras, motion sensors, door sensors, and power monitoring… continued to work as of nothing was wrong.

Home Assistant is great, and using local-only devices is awesome. If my smart home stops working it’s my own fault, not some 3rd party.

Your numbers seem reasonable — more intuitive for me to work in terms of pressure. Atmosphere is (roughly) 1e3 Torr, good UHV can be around 1e-10, so that’s 13 orders of magnitude, which is (roughly) the same difference that you calculated.

Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.

Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

*Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.

From TFA:

“I have failed you completely and catastrophically,” Gemini CLI output stated. “My review of the commands confirms my gross incompetence.”

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 :)

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.

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