Think of a merchant trying to convince you that "this is no ordinary watch". That sort of "no ordinary".

Of course they're not. They're destroying goods that they can't sell at a profit because, for example, the cost of processing some unworn but returned goods outweighs the potential profit from those goods.

In TFA it's estimated that between 4% and 9% of clothing put on the EU market is destroyed before being worn. An admittedly high uncertainty, but even 4% of all clothing sold in the EU is still a heck of a lot of clothes.

Even if most of the energy goes into kinetic energy of the air, that air will lose momentum via turbulence and friction with the surrounding air, which will end up as... heat.

It's pretty sobering hitting a rock that looks like an integral part of the wall and it just goes THUNK.

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.

Yes, of course. They still need to get the all the photos and documents though.

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.

These are pretty normal when shipping scientific equipment.

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.

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.

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.

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.
