You will want to reconsider the name if you plan to have a presence in Australia or New Zealand. "Abo" is an ethnic slur similar in offensiveness to the N-word.

To be frank, if you die, isn't it much more likely your friends and family will just stop using your homelab setup? They'll switch back from Jellyfin to Netflix, replace the smart light bulbs with regular ones, etc.
Yes, of course. They still need to get the all the photos and documents though.
Sometimes when I think about my home network, I think about it in terms of what will happen when I die and what I will be inflicting on my family as the ridiculous setups stop working. Or like, how much it would cost a police forensics team to try to make any sense of it.
I think "home labbing" fulfils much the same urge / need as the old guys (I hate to say it but very much mostly guys) met by creating hugely detailed scale model railways in their basement. I don't mean that in a particularly derogatory way, I just think some people have a deep need for pocket worlds they can control absolutely.
I'm glad to see this comment here. People build these projects for family and friends - which is great - and encourage their use, without considering what happens if the only sysadmin suddenly dies. You wouldn't let one person at work hold all of the keys, so the same should be true for your homelab.
While I haven't given all of my keys to my family, there's a clear route for them to get them, and written instructions how to do so. Along with an overview of the setup and a list of friends and colleagues they can turn to, this is enough for them to get access to everything and then decide if they want to carry on using it, or migrate the data somewhere else.

An archduke shot in Bosnia, or an incident near a bridge in northern China?
This is a good point, but the average person is unlikely to hear about a skirmish on a different continent, and then know they should start stocking up on tinned food and bottled water. The problem is with the volume of information. It's impossible to take all of it in, so you need to pick and choose, and stay within your own limits. Some people might have the capacity read a whole newspaper's worth a day, others can only manage the local headlines.
I heard that NIF was never intended to be a power plant, not even a prototype of one. It's primarily a nuclear weapon research program. For a power plant you would need much more efficient lasers, you would need a much larger gain in the capsules, you would need lasers that can do many shots per second, some automated reloading system for the capsules, and you would need a heat to electricity conversion system around the fusion spot (which will have an efficiency of ~1/3 or so).
Any truth to that?
From my time in fusion research circles, you're correct, but it's also not a simple "weapons or energy?" question. It could only have ever been a pure research facility. At the time of design, the physics wasn't certain enough to aim for net energy gain. Where the weapons research came in is in the choice of laser focus. Instead of "direct drive", where the lasers directly strike the fusion fuel, NIF lasers strike the inside of a Hohlraum, which produces X-Rays that then heat the fuel. X-Ray opacity is an important topic in nuclear weapons research.
Bear in mind that I wasn't directly involved, and this my impression picked up from conversations during my time in fusion research, which was about 10 years ago.

Based on the title, I was hoping for an explanation. Instead the article is a collection of "maybe it's this?" points.
It's still great that Cornell Lab provide resources like this. Another project of theirs, BirdNET [0], is fantastic for identifying bird song.

Came looking for this comment. I was a heavy Matlab user, having learned it during University. I started getting frustrated with it though, and wanted something else that would let me go from simulation or experimental data to visualisations as fast as possible. Spyder was the answer.

Directionality is a normally an almost completely unwanted quality in speakers. You want speakers to be heard equally well from all directions (that are frontward of the speaker's baffle). That's one reason why speaker boxes use multiple speakers, and these get smaller for the higher frequency ranges. "Dome tweeters" are shaped as such in order to radiate all around.
A "full range" speaker will send the lows in all directions but the highs mainly in the direction of its axis. A listener caught in the beam will hear a shrill sound, whereas someone off axis hears it muffled. Guitar speakers are like this; particularly the 12" ones and particularly in the 4x12 cabinet arrangement. Sometimes musicians use dispersing devices mounted on the speakers, like "beam blockers". Or the speaker is picked up by a microphone close to it, so that the audience hears it fro the PA system (which solves the sound dispersion problems in its own way).
There are situations in which it is desirable for a speaker box to "beam", like when it is mounted far away or high above a target listening area that is relatively small, calling for the speaker to be a kind of spotlight.
Speaker directionality gets interesting once you get to arrangements for festivals and concerts. Ideally the audience should all be able to hear well, which is difficult to achieve over such a large area and with multiple sources.
But you also don't want the neighbours to complain about the thumping bass. A number of subwoofers pointing backwards, with the right phase delay, destructively interferes with the most offensive frequencies and reduces the sound intensity behind the stage. It's called a 'cardiod' arrangement, because of the shape of the resulting sound intensity distribution.
JavaScript land fares little better.
IMO it’s because php and js are so easy to pick up for new programmers.
They are very forgiving, and that leads to… well… the way that php and js is…
I've heard it said that one of the reasons Fortran has a reputation for bad code is this combination: lots of people who haven't had any education in best practices; and it's really easy in Fortran to write bad code.
