Now everybody wants to put funds to attract talent from Harvard. On one side ofc is great. On the other side it kinda saddens me to see that suddenly there's additional UE funds for research... that have been never invested in places were they are urgently needed for years.

Most 'top students' in Spain, Greece or southern Italy cannot join a PhD in their country because of lack of funding and cutting-edge labs. A 'big PI' in Spain has usually 3-4 students, counting away some outliers in Madrid/Barcelona. A Prof position does never come with a 'starter pack', a lab, or students. These countries do usually well in math or theoretical physics because it's cheap. If you look at experimental facilities, we fall behind. Our unis have problems hiring new research personnel, have outdated labs, etc etc.

The US does a terrible policy and then suddenly everybody is considering what can we do to help them. And don't get me wrong, I believe it's a good thing to help people and a great opportunity to catch some exceptional scientists. Just saddens me to see top European talents absolutely wasted, for years, and there is little to 0 conversation about that in other places. As someone who has struggled a lot with this situation, it feels sad.

Name your variables meaningfully.

"j" is not a useful variable name. You are not a minifier. Do not assume people understand the role of "j" intrinsically.

Write code to be understood.

Name meaningfully.

Comment about *why* a thing, code should self-explain *what* and *how* a thing.

Don't make shortcuts while coding just because you know what you're thinking and doing in the moment. You won't later.
