If you're interested in the numerical side, I'd recommend "Numerical Linear Algebra", by Trefethen and Bau.

Julia is pretty cool, I made a point to experiment with it a bit last year. What we work on is pretty heavily object-oriented, and at the time it seemed to me that the types system seemed a bit too awkward to use to for our purposes at the

I'd also add to this that the government is pretty heavily invested into python (at least NASA, DoD, and DoE based on direct experience). It's kind of becoming the scientist's and engineer's new Fortran.

That is an interesting idea. But even more so, I would certainly pay for a full MOOC on low-level OS development from scratch derived from it. Terry seems to have a rare and very useful skillset.

I work at NASA. I do have a pretty high level of autonomy in my work (with room to experiment with new technologies and processes), but it's a very hit-or-miss thing for each of the programs and projects. I know many colleagues who are

Cool idea. I just made a quick implementation for those who want to use it/see it live: https://github.com/thearn/game-of-life/blob/master/image.py I'll make a quick .gif, if folks are interest

Excellent. If we're talking civil aviation and space, it may be one of the hardest industries to disrupt thanks to regulatory capture (and a million other things), but from a technical standpoint there is a tremendous amount of room fo

I'm interested to hear more about the one aerospace startup that they funded in this class.

Interesting, it's basically trivia instead of an aptitude test. The ASVAB is certainly an improvement.

Clicking this, I was expecting to read a damning article about the state of recent research in numerical linear algebra. Looks like I can relax.

It's a good question. It's clearly worth it for some. For me, I own a 1800 sq. ft. home on 4 acres outside of Cleveland valued at $170k, in an area with excellent schools. The career prospects in NY and SF are far better, but I&#x

I'm becoming more convinced over time that having engineers learn MATLAB as their first technical computing language really hurts them in the long run. You always end up in a state where you have to do very convoluted tricks to do anyt

The classic standard normal + chi-squared example is also one worth remembering: Let X ~ N(0, 1), and Y = X^2. Cov(X,Y) = 0, though they're obviously not independent.

I currently work on one of these: https://github.com/OpenMDAO/OpenMDAO-Framework It looks like the fork linked to on code.nasa.gov is a few years behind.

That is true. Also step increases are fairly regular.

yep, $30/hr is roughly the salary of a GS-12-01, which is what fresh-out PhDs are usually hired in at in federal service: http://www.opm.gov/policy-data-oversight/pay-leave/salaries-...

This was the first browser that I learned to use! Worked over the Cleveland Public Library's BBS Telnet in the early 90s.

Aside: I do computational applied math for a living, and haven't yet seen proofs.wiki before. Is it fairly new? An editable wiki just for formal proofs does seem like a decent idea.

It's certainly faster and more responsive on my laptop than the current version of Google Maps.

Genetic algorithms and simulated annealing are probably some of my favorite topics which ended up not being applicable in my day job, despite working very heavily in non-linear optimization. Our problems are of the size where gradient-based

As a software person at NASA, one caveat to note is that this is in part due to the intricacies of the federal civil servant system. Frankly, it is very hard to punish or fire government employees or some prime contractors, so most often (e

I feel a similair way about folks who describe software developers as "ninjas", "samurai", etc. As odd, very misplaced appropriations of east asian themes/imagery.

My guess is the main advantage is feasibility - a manned airship-like laboratory in the upper atmosphere of Venus is something we could likely accomplish sooner than a manned mission to Mars, if we chose to make that a priority. Though the

The hype for me is tempered pretty heavily by what happened to Clang. I'm still very curious what Magic Leap is all about though.

Very cool concept! I guess it's also another point to show that the number of jobs (in this case, lab assistants) that can't be automated away is getting smaller and smaller. Just an observation though, I'm not a luddite abou

Your story very much mirrors my own, at the time it was the best option for someone with no money and a GED. The experience was something that I needed. But I did become jaded very quickly by what I saw around me. My time in uniform was a n
