Especially after adding in all the power draw of the automation requires…
What exactly is the incremental power draw for automation? My network gear and server (a little nuc) are sunk power costs as I self host other services.
Idling, my home uses around 100W with the fridge off. One 10W light is an additional 10% of my power budget, and I have a lot more than one light in my house. I also pay about $0.40/kWh.
I can be a bit neurotic about turning off lights when I leave a room, so Home Assistant was a nice way to free up brain space for me. A few motion sensors here and there + some simple automations, and the lights mostly handle themselves. Zigbee sensors and Zigbee or Matter-over-WiFi bulbs, so everything is local. A free VPS+WireGuard setup means I can access them remotely should I need to, with TailScale as a backup.
Cloud failures mean I can’t access remotely, but local control is unaffected—if my smart devices stop working it’s almost certainly my fault :)
You’re right, for new drives it looks like a little more with this 20GB retailing for $230, or $11.50/TB.
For refurbished, I recently got a factory renewed 12TB Seagate for $112 ($9.33/TB), but that price is now up to $199 for the same drive (!).

About 4.4TB, but that’s all architectures and (I believe?) all distributions (stable, testing…).
If you only want source+all+amd64+arm64, and only want stable, it will be smaller of course.
Not nothing, but at $10/TB or so, it’s not much.
And if you’re following 3-2-1, I’m pretty sure the “1” is already handled for you :)
In grad school I bought a blue (405nm) laser pointer. It was supposed to be <5mW, but I measured it at over 70mW.

Atomicity (something happens in its entirety or not at all), consistency (database is always in a valid state — if the database has constraints, they will always be honored), isolation (transactions don’t step on each other), durability (complete transaction is complete even if there’s a power failure).
Not a database expert, my parenthetical explanations may need work.
Some would call the former command cat abuse.
In short, unless you want the contents of a file printed to stdout (or multiple files concatenated), the command can probably be written without cat, instead using the filename as an argument (grep pattern file) or IO redirection (cmd < file).
Stylistics and readability are another thing though.
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.
Most Linux filesystems, being case sensitive, won’t find the SUDO command.
…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.
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.
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.
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.
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.
Oracle Free tier, amd64. Only use it because it’s free—limited bandwidth, but given I have slow upload at home it’s never really been a bottleneck. Hate to admit it given it’s Oracle, but I’ve been completely happy with it.
If I switch to a paid VPS I will probably go with racknerd (suggestions welcome though if you have thoughts).
