> It is amazing how many statisticians are still using pseudo-inverses in numeric computation I'm not entirely sure what you mean - pseudoinverse/SVD methods definitely have their place.

Python is my usual go-to language for technical computing, bit Julia is a lot of fun! I'd be curious to hear more from folks who have made use of it in "production" (sort of a tricky label in scientific programmiong) code.

Have you had any concerns yet about data provenance? Granted, I've only done queries right on Wolfram Alpha itself (and not with an api), but figuring out precisely where the original source data came from is sometimes pretty hit-or-mi

It reminds me of many systems I've seen where you really need to be a developer of the platform to intuitively make use of it for non-tutorial problems.

Yikes, sounds like a pretty tricky mixed integer programming problem. What are the usual go-to techniques for optimization? branch & bound?

The author mentions Trefethen-Bau, “Numerical Linear Algebra” as a good reference. I couldn't agree more, it's a great resource.

Unfortunately under this hiring program, yes. But if a listing with wider scope is posted, I will update this or include it in next month's listings on HN.

Yep, they probably used an off-the-shelf method for that. It's often called image interpolation or "inpainting" ( https://en.wikipedia.org/wiki/Inpainting ).

NASA Glenn Research Center, Cleveland, OH. We have a position listed on usajobs.gov[1] (which is not the easiest site to search) for software development here. The listing says "internship" for the hiring program, but this is real

I think I may have lucked out, my advisor was absolutely awesome. But, he only has 2-3 doctoral students at a time. I know in large programs, some advisors end up taking on far more than that.

Writing a one-off throw away analysis script? Better consult NPR 7150.2A and matrix it correctly! It's not about safety. It's about checking of a box and satisfying a process.

Better TOC software would be great (though I haven't been in uniform in almost 6 years). But I remember ASAS and ASAS-L being pretty terrible for what they were.

I like it. Any way to get third-party python libraries (e.g. numpy, scipy) to work with it too, in a python project?
