Exactly. On top of that, a typical apt update/upgrade takes less than a minute. For some users, the need for a reboot after a kernel update is a pain but you can do that when convenient.

Any windows update beyond antivirus seem to take at least 30 minutes, uses half the machines resources, and requires a reboot (or two sometimes).

Never been in a fab I see.

For most processes, only the first few layers (out of 50 or more) are printed with the highest resolutions tools. As you move up the device stack, the layers have both larger dimensions and are thicker. Tools like EUV can print very small features but they also have a very small depth of focus. Because of this (and cost and throughput), a fab will have just a few of the highest resolution tools, and a bunch more of the lower resolution tools all the way up to non-DUV (365 nm I-line tools) that only have 300 nm resolution. Fabs will continue to have DUV tools for a long time to come.

I have no idea if this new machine is actually capable of anything, but they are claiming immersion DUV. This is the most advanced DUV technology utilizing a layer of water between the lens and the wafer to increase numerical aperture (and make smaller features). Immersion and EUV are both embargoed from China. The Chinese are able to purchase dry (non-immersion) DUV and UV machines from ASML.

None of descriptions describe it this way, but it seems likely that their "wave spring" adjusts the resonance frequency of the system. They talk about getting vertical motion 3x the wave amplitude under normal conditions, so it must be something like that. Because it is on resonance, there are already big differences in the forces (during parts of each cycle) on the anchor under normal wave conditions than you would expect from buoyancy during wave motion.

I don't think they are applying breaking forces during a storm, they are adjusting the system to be off-resonance to the wave to minimize motion. There will be large forces on the anchor during a storm, but that seems like it would be one of the primary design parameters.

The closest mechanical analog (but not a great one) I can think of is paddle ball (a rubber ball attached to a wooden paddle with a rubber band). Off resonance the ball flops around randomly, and on resonance it has a very large amplitude.

I was once at a meeting (sometime after that particular metric/imperial fiasco) where a bunch of astronomers and instrument builders were discussing a new satellite (that was never built). They had some NASA payload engineer give an overview of the launch package they might use. During his presentation he said "it will be 5 meters in diameter and 35 feet long". I nearly fell out of my chair laughing.

I think those numbers are crazy high too.

I had to have a minor procedure at the hospital and they really want you to use their free valet parking. Not only could the attendant not drive a stick, it seemed like he had never seen or even heard of a manual transmission.

Not long after that I was thinking about buying a new car and trading my manual in. The car dealer only had one salesman (out of about 10) who could drive it to the service bay so someone could inspect it.

Spot on. The paper said they estimated the three crew that were imaged received between 0.3 and 2.7 mSv - I guess different crew members had different images taken, and that the chest images used a dose of 0.12 mSv and the abdomen/pelvis images were 0.36 mSv.

Also interesting was that they did some testing of doing non-destructive testing x-ray images of hardware.

You mean "Pump and Dump"

No doubt that is some of what's happening now, but I don't think it's all about stock price. I'm pretty convinced the both the memory and logic companies are going to build a bunch of new fabs, make more parts than they've ever made only to have demand drop to more sensible levels.
