mine were erupted already. at least removing was easy (local anesthesia + pliers... but the sounds!)

Unfortunately wisdom tooth removal is basically required for polar programs deployment, otherwise I'd surely still have mine

Unfortunately polar programs requires a dental PQ for antarctic/Arctic deployment, so I have to do whatever they say. Sigh.

If only we could figure out how to get rid of the pesky ionosphere....

Greenland is much better logistically in some ways (I work on experiments both in Greenland and in Antarctica), but the ice in Greenland is unlikely to be as good for IceCube as in Antarctica, due to a presumed larger number of dust layers from dry periods in Europe.

The US has a research station at Summit Station Greenland but compared to South Pole, it's spartan (like, the first time I went there, I slept in a tent because of lack of hard-sided berthing, but then a Polar bear came a few years later and now hard-sided berthing is required). There are longer-term plans to improve the station in Greenland but we'll see.

Well, this is a pretty perfect usecase for AI (although it's also easy to just get shapefiles from NE and do it yourself, obviously).

Interestingly all of UAE, Yemen and Saudi Arabia have significant discrepancies between the World Factbook and their shapefiles (in every case overestimating), probably all related to not having had a demarcated border in the Rub Al Khali.

It also fills up the hard drives on shared server, where each user up to 5 GB of vscode nonsense.

Also, I realized that students are likely to use vscode to connect to embedded Linux machines and fill up their emmcs (and RAM), so I came up with a partial solution for our experiment's yocto image (https://github.com/RNO-G/meta-rno-g/blob/main/recipes-suppor...) , but a more general solution would be nice. Probably better to just not allow any node process to run via LSM.

I bet the 137 isn't though since that's a common satellite downlink band. Swarm who they acquired used that

The photons don't slow down. It's the phase velocity that slows down because the electrons in the medium rearrange themselves in the presence of electromagnetic radiation, causing interference reducing the phase velocity of a wave. This is why the dielectric constant is related to the polarizability of a medium.

It's more about how fast communication can happen within the medium. The Cerenkov radiation happens because electrons can't "find out" about the charged particle coming through, creating a shock, similar to a sonic blast or the wake of a boat.

Hopefully I got this more or less right... I build detectors to look for Askarayan emission (a related phenomenon in the radio) but I'm definitely not a theorist :).

These are either incidental or unauthorized transmissions. Not the Ku band downlink to terminals.

Yes, a yubikey works for when I really need it, but it's enough friction to take out out and plug in that it's just annoying enough.
