A lot of people do claim it's worthless to learn math or, at an extreme, writing correctly. That's part of the problem.

Thanks, I think it's fixed. Unless I introduced another bug.

OS X uses FreeBSD date which has totally different cmdline options. I did actually write an awk script that works on Centos 6, I'll upload that shortly. (Edit: I think instead of -jf, you can use --date= on linux.) The event suggestion is g

True. He does have about a lot more data over a 40x longer time interval, so the noise smoothes itself out more. Unless you also mean I should have formatted the matplotlib graph better? Mathematica actually has quite nice plotting in gener

So besides the temporary discount, what does this offer that's significantly different from AWS? For example the pricing and naming scheme of HP Cloud Compute and EC2 are more or less identical, and the machine specs are on average the same

What about Intel's mobile presence? Because they don't have much of one, and small devices are only going to continue to proliferate in the near future. It's a bold claim that "NVIDIA will go out of business" because Intel can produce integ

I am familiar with how China operates. Being close with the govt/CCP in China is standard practice. So you must also be aware that Foxconn has come under very intense media scrutiny in _China_ since a couple of years ago. Consider this sequ

What Apple has going for it here is the fact that it has Foxconn as a key manufacturing partner, which is a huge employer in China. That may give it some political power. Foxconn is a Taiwanese company. That doesn't count as "po

Actually, his primary example of "simulated learning" is more modest than you put it. Essentially, researchers really did and still do want to have computers as a tool for performing experimental simulations and using computing for communic

Fortran compilers (gcc has a Fortran 95 frontend) have long offered optimization levels beyond -O3; i.e., -O6 is a decent upper bound among popular free and commercial compilers, not just gcc/gfortran. The author probably came from a HPC ba

That's interesting to see the related searches between the two. Github users, unsurprisingly, also like Node, MongoDB, etc., whereas Wolfram Alpha users play Minecraft and read webcomics (also popular among Github users). In other words, Wo

Confucianism is historically the heart of Chinese culture. Taoism has never been as singularly influential in China as Confucianism has, nor is its "resurgence" sweeping away Confucianism. Assigning the idea of e.g. fatalism to "mostly Taoi

Just to be clear, Difference Engine no. 2 was completed in 2 parts: in 1991 and 2000. However work on the _Analytical Engine_ has just begun in the planning phase, and excitingly it will be a crowdsourced endeavor.

The main reason I'd see for originally including PNG color space metadata is to correct for the inconsistent gamma between OS X 10.5 and earlier (gamma 1.8) and Windows (gamma 2.2). Snow Leopard and Lion have switched to 2.2 so the problem

If you're going to raise science on a pedestal, you should write a comment other than "Oh it's science, we should trust whatever those scientists are doing." (C.f. the Milgram experiment.) We don't need to mindlessly praise research; we hav
