I was interested in what it means to be “trump-linked” in this case. So I looked at the danish media and basically: Greenlandish company “White Flame Energy A/S” have official licenses and permissions to look for oil. In 2024, White Flame Energy were bought by british 80 Mile PLC, and thereby is in control of the licenses (although from greenland media sermitsiaq.ag they should have has oil research licenses since 2015). The american company “Greenland Energy Company” has entered partnership with 80 Mile, and they are the investors that will fund the project and run the drilling operations. The trump link seems to be Greenland Energy’s chairperson “Larry Swets”, who appears in Trumps circle (According to The Guardian).

So it seems like a capitalistic invasion; pay the bill and get to run the operations, while the brits do PR control with the locals.

I imagine oop refers to the water in the pipes getting cold over night in winter, and they’re probably not patient enough for the hot water to start flowing.

Thought I would mention Guix. I don’t know about using it as an OS but just the package manager is so nice to build reproducible software environments (although disclaimer I discovered this myself a few weeks ago). At least as close you can get without including proprietary hardware drivers. Building MPI applications on my laptop and moving them to an HPC cluster with full performance feels like magic.

Imagine there are two balls, a red and a blue. You want to communicate to your friend rolling the only blue ball to them. In a ferromagnet there are only blue balls, in an antiferromagnet the blue and red balls are glued together and in an altermagnet there are both balls but they go in different directions so you just need to orient yourself correctly.

The antiferromagnet can’t be used for spintronics, the ferromagnet can but big magnetic field disturb other parts in a circuit.

Altermagnets are pretty interesting because their most defining feature is not the magnetic order in the materials. They look like ordinary antiferromagnets where the spins of adjacent atoms point in opposite direction and compensate each other, so no large magnetic fields are created. What differentiate altermagnets from antiferromagnets is how the electrons with different spin behave. When pulling current through altermagnets it will consist of purely spin up electrons along one crystal axis and purely spin down along orthogonal crystal axes. Thus the spin currents have a ‘alternating’ pattern, giving the name altermagnet. This is primarily exciting for the field of ‘spintronics’ which is all about creating technologies using spin currents.

Not all altermagnets are equally interesting, many antiferromagnets can be reclassified to altermagnets but they are generally insulating. (fun fact the first ever measured and textbook antiferromaget MnF2 is actually altermagnetic) So materials discovery of new altermagnets is important to find metallic, semi-metallic or even super conducting altermagnets.

This certainly could be part of the motivation for publishing it this way, to make themselves more noticed by the big players. Btw, publishing in open source nature is expensive, it’s like 6-8000 euro for the big ones, so there definitely is a reason.

While in not in the field either, I do know that it is quite unusual in computer science academics to publish in actual peer reviewed journals. This is because it can be a long process, and the field is very fast moving, so your results would be outdated by the time you publish. Thus, a paper is typically synonymous with a conference proceeding, and can be found on arxiv. I found this Paper on the arxiv from 2017/2018 which seems to be when this paper was originally published for the scientific community and presented at a very “good” (if I had to guess) conference. Google scholar says this paper has 650 citations, so it probably has had quite some impact. However, I would guess this method is well known and is already implemented in many models, if it was truly disruptive.
