My home server doesn't need to be high availability, and the BIOS is set to whatever state prior to power loss. I don't have a UPS. However, we were recently hit with a telco outage while visiting family out of town. As far as I can tell there wasn't a power outage, but it took a hard reboot of the modem to get connectivity back. Frustrating because it meant no checking home automation/security and of course no access to the servers. I'm not at a point where my homelab is important enough that I would invest in a redundant WAN though.
I've also worked in environments where the most pragmatic solution was to issue a reboot periodically and accept the minute or two of (external) downtime. Our problem is probably down to T-Mobile's lousy consumer hardware.
As another commenter said (but got downvoted to oblivion for some reason), its not really about uptime for the homelab, its about graceful shutdown/restart. And theres well defined protocols for it (look up network ups tools, aka NUT).

These are different requirements. The issue I described was not a power outage and having a well managed UPS wouldn't have made a difference. Nothing shut down, but we lost 5G in the area and T-Mobile's modem is janky. My point is that it's another edge case that you need to consider when self hosting, because all the remote management and PDUs in the world can't save you if you can't log into the system.
Of course there's all you need is a smart plug and a script/Home Assistant routine which pings every now and again. There are enterprise versions of this, but simple and cheap works for me.
I've found that for any sort of reasonable task, the free models are garbage and the low-tier paid models aren't much better. I'm not talking about coding, just general "help me" usage. It makes me very wary of using these models for anything that I don't fully understand, because I continually get easily falsifiable hallucinations.
Today, I asked Gemini 3 to find me a power supply with some spec; AC/DC +/- 15V/3A. It did a good job of spec extraction from the PDF datasheets I provided, including looking up how the device performance would degrade using a linear vs switch-mode PSU. But then it comes back with two models from Traco that don't exist, including broken URLs to Mouser. It did suggest running two Meanwell power supplies in series (valid), but 2/3 suggestions were BS. This sort of failure is particularly frustrating because it should be easy and the outputs are also very easy to test against.
Perhaps this is where you need a second agent to verify and report back, so a human doesn't waste the time?
Also check if you're in education at any level. Most university libraries subscribe to what used to be Safari and you can SSO the full (enormous) catalogue. I didn't realize this for quite a long time as it's not widely advertised. There are ton of books that aren't the traditional animal-drawing tech titles, including Manning, as well as some lecture series.
But the app is pretty kludgey and it's way more locked down than other publishers who will give you chapter PDFs.
At least it's a good way to skim books to see if they're worth buying a physical copy.
1. Compliancy with relevant standards. HIPAA, GDPR, ISO, military, legal, etc. Realistically you're going to outsource this or hire someone who knows how to build it, and then you're going to pay an agency to confirm that you're compliant. You also need to consider whether the incumbent solution is a trust-based solution, like the old "nobody gets fired for buying Intel".
2. Domain expertise is always easier if you have a domain expert. Big companies also outsource market research. They'll go to a firm like GLG, pay for some expert's time or commission a survey.
It seems like table stakes to do some basic research on your own to see what software (or solutions) exist and why everyone uses them, and why competitors failed. That should cost you nothing but time, and maybe expense if you buy some software. In a lot of fields even browsing some forums or Reddit is enough. The difference is if you have a working product that's generic enough to be useful to other domains, but you're not sure. Then you might be able to arrange some sort of quid pro quo like a trial where the partner gets to keep some output/analysis, and you get some real-world testing and feedback.
That's specifically for AI generated content, but there are other indicators like how many affiliate links are on the page and how many other users have downvoted the site in their results. The other aspect is network effect, in that everyone tunes their sites to rank highly on Google. That's presumably less effective on other indices?
This is Black Friday pricing at least, if you're willing to shuck. Seagate drives are still sub-$10/TB which... a single 24-26TB is enough for all my photos (ever), media and some dataset backup for work. I'm planning to backup photos and other "glacier"-tier media like YouTube channels to BluRay (a disk or two per year). It's at the point where I'd rather just pay the money and forget about it for 5-10 years.
I built the case from Makerbeam and printed panels, an old Corsair SF600 and a 4 year old ITX system with one of Silverstone's backplanes. They make up to 5 drives in a 3x5-1/4 bay form factor. It's a little overpowered (a 5950X), but I also use it as a generic server at home and run a shared ZFS pool with 2x mirrored vdevs. Even with inefficient space it's more than I need. I put in a 1080ti for transcoding or odd jobs that need a little CUDA (like photo tagging). Runs ResNet50-class models easily enough. I also wondered about treating it as a single-node SLURM server.
You don't need oral exams, you just need in-person. So a written test in the classroom, under exam conditions, would suffice.
In this particular resolution example, it would be quicker to ask the student some probing questions versus have them re-write (and potentially regurgitate) an essay.
The UK comparison for home cooking vs fast food breakfast should be really be Wetherspoon. Spoons makes a solid stodgy full English breakfast and bottomless coffee for 5-7 quid depending on the size. Classic hangover food, and you can start the morning where the night ended.
Obviously you can beat it with home cooking, but the calorie value for a sit down meal out is compelling: 1300 cals for 7.50 (more if you go for hot chocolate).
Wetherspoons is amazing and a great replacement for McDonalds. They bring the food to your table, with cutlery, on a plate and you get unlimited coffee and tap water. I paid £4.78 for a muffin of sauage+bacon+2 eggs+hash brown and unlimited coffee this morning.
You got to choose very carefully from the menu as lot of things aren't good value.
On film availability. It's relatively easy to slit film to width, with little jigs that are machined or 3D printed. This is popular for Minox "spy" cameras since new 8x11 reels are $20+ and you can refill an old plastic cartridge if you're very careful. The stock is about 8-9mm wide depending on the camera and so a 35mm roll will yield 2 strips that can be cut to length.
Some enterprising person makes a machined an aluminium Minox film cartridge, which is expensive, but solves the problem of the originals being incredibly fragile. It doesn't take many retail rolls to justify the cost though.
