This has got a "Bobby Tables"[1] vibe to it. While I personally do not like the concept of adjusting data to fit a tool, as others have pointed out, Excel, for better or worse, is ubiquitous. To the obvious detriment of genomic

I worked for a company in SF from 2017 until 2019. Then a Seattle based company. SF was bad then, around the edge of Chinatown and the financial district. But I'm from NY, so I can deal with that. Generally. The mentally ill scre

When faced with such discussions about small companies being higher risk, I'd trot out Sun Microsystems, GM, Chrysler, etc. There is risk. There is always risk. Risk has little to do with size. It has a great deal to do with managem

I'm not sure of what issue you have with my statement. For me, it is a painless download + sh NVIDIA-....run. I have mostly newer GPUs, though the 3 systems (1 laptop and 2 desktops) with older GTX 750ti and GT 560m run the nouveau d

I know about the PGI purchase ... was unaware of the Intel link to MSFT. Huh.

I was getting better performance out of the NVidia HPC SDK compilers, but then again, the old PGI compilers it is based upon (with an LLVM backend now), have always been my go-to for higher performance code. I've got some Epycs and Zen

Back when I had my own HPC company, we often consulted on RFP specs for customers building clusters. After a while we started building our own clusters. A well known large/prestigious university on the East Coast US called us to help

AMD[1], NVidia[2] do "make" their own compilers. AMD is notorious for a "build it and they will come" mentality. Despite the fact that this hasn't worked. AMD needs to make it easy to adopt their hardware, and th

This 1000x. I am flabbergasted at the attacks on scientists explaining current understanding, until I realize that the people attacking very rarely comprehend the process. This isn't a slap at people attacking scientists, it's ve

I used NR a bit more in grad school (late 80s/early 90s) than undergrad. I had (have) the Fortran version. I used some of the ODE integration bits in some code I worked on in grad school, though we put that project away after we swit

Have a look at Makie.jl[1] in Julia. I've been using it for exploring large data sets recently. Ticks your boxes. Jupyter version is image based though, as Jupyter is inherently static. You could use Pluto.jl[2] to build a reactiv

I had aunts, uncles, and various family friends with numbers on their arms. I vividly recall their expression when I asked (I was like 3 or so, late 1960s) if I could get one of those for me. I thought it was cool. I only learned much la

Yeah, I read that, and wondered if that is a real justification for, well, anything. I have and can run Linux binaries I had compiled (statically) from the late 90s. Doesn't mean that I should. If you are running ancient games, run t

My Ph.D. wasn't from a top 20 school. But my thesis advisor was a student of a well known Nobel Laureate (he won the prize while she was his student). I'd noticed this trend in faculty back in my undergrad days, when looking at

I've got a somewhat different critique of the article, in terms of the expected lifetime of the codebase. Part of this goes to language choice, feature choice in the language, etc. The author of the article skims this in the paragrap

Perl was, and is still, a remarkably powerful language. I used it starting in the early 90s to generate correct input decks for my simulations on supercomputers. Then I used it to orchestrate my (many) runs across a wide range of systems.

Fortran used to get lots of hate from the C-like crowd. Maybe it still does. This said, it is a modern, very high performance computing language. It is easy to, as the article notes, adapt the language to fit the algorithm, rather than do

I'm guessing they (authors of battlezone) and the article aren't aware of BZFlag[1]. I started playing it in 1995 on SGI machines. I now play it on my laptop. This is definitely 3D, and the tanks can jump. [1] https:/&#x2F

I agree. There's far less of a cognitive load for developers associated with representing an expression as written, if you don't need to mess with indices, in order to accommodate the language and its vagaries. One should not nee

Much of Julia language is written in Julia. So the 'external package' is just an extension you install/use if you wish. A distinction without a difference.

Agreed. I'm a (very) long time Fortran user, and a more recent C, Python, and Julia user. I'd agree that scanf is a pain. The chomping/parsing bit can be, in all cases, hidden behind a convenience function, which if you li
