I am in the top 3% but I don't know if that means a lot or not much :-/

I have always maintained that real mathematics starts when you address the infinite. I don't see how you can get anything interesting (like analysis, differential geometry, topolog…

> uutils now runs the upstream GNU coreutils test suite against itself in CI. That’s the right scale of defense for this class of bug. That's the minimum, it is absurd that they di…

The article is badly written. This has nothing to do with fractals, they are talking about the assumption that there is an UV fixed point for all physical laws, which can even be t…

As a former Theoretical Physicist, this result is remarkable. I myself I tried to use AI for calculations in Perturbative Quantum Field Theory and I was impressed. I agree with the…

My barber is 75+ and he says that he has no intention of ever retiring, until he is forced to by health reasons.

I like far-future concept-driven science fiction, is there something for me too?

I am old. The time of the old Internet corresponds to my Ph.D. years, so I was very much an adult. I still miss it ;-)

Nowadays I am on the other part of the fence, I am the interviewer. We are not a FAANG, so we just use a SANE interview process. Single interview, we ask the candidate about his CV…

Finally somebody making sense in this thread!

I am scientific Python programmer. 99% to 100% of my programs require parallelism, but it is ALWAYS embarrassingly trivial parallelism, nothing is ever mutated and I never need loc…

I remember when I took my course of "Theoretical Physics" (so called, it was an Introduction to Quantum Field Theory in actuality) and I realized that particles do not exist. It wa…

I was in your situation 20 years ago, as a postdoc in Theoretical Physics. My advice is to contribute to some known Open Source project, so that you have some provable programming …

This is good advice and my own software is following it: $ oq info cfg Looking at the following paths (the last wins) /opt/openquake/oq-engine/openquake/engine/openquake.cfg /opt/o…

Pity that I never met antirez in all this time. I first heard of him from David Welton who was a coworker of mine in 2004, well before the existence of Redis. But hope is not lost.…

>In my experience teaching programming, we spend very little time helping students actually write code. >Instead, the mentors mainly deal with problems of tooling – “it says ‘EADDR…

I use numba a lot nowadays. Works perfectly well on all platforms (linux, windows, mac, even the M1) and gives speedups as expected (few percent for already well vectorized numpy c…

Having been on both sides of the peer review process in my field (Theoretical Physics), I say we should completely abolish it. Just publish the papers on the preprint archives. Som…

Speaking as a physicist, I have always hated this nomenclature. There is no vacuum at all. The universe is filled with quantum fields, they are the source of the Casimir effect. Te…

I work as a research engineer in Italy. My path was academia (Physics)->industry (Finance)->mix. The "mix" where I am now is a strange case: it is located inside an university, nea…

This is quite interesting. As a theorist, I have 100% confidence in inflation. The problem of inflation is that there are too many variations on the idea, if we can begin to throw …

It is more or less the same in Italy and in most European countries, it is not only Germany.

Actually this is classical general relativity, the math is not particularly advanced. When I was doing Theoretical Physics I would have considered this paper "easy", at least relat…

I know Christoff Wetterich! From the time of my Ph.D. when we were working the Renormalization Group. I met him a few times, we were working on similar things but in different grou…

I left academia in 2003, after 3 postdocs in Theoretical Physics (Quantum Field Theory, Thermal Field Theory, some Cosmology). The reason was certainly not the money, rather job se…
