I like `<editor> <ctrl-t>`; ctrl-t opens fzf and pastes any selected files onto the command line. If you choose to abort you end up back at the prompt after `<editor> `.

What's the reason for 'asm("");' in 002.c (and other c codes)? All I can see that doing is intentionally breaking the compiler's ability to optimize over loop iterations, which puts rust a huge advantage over c.

Shouldn't it be 'float * restrict a'?

When could one get into trouble thinking that "restrict == this will not alias"? If X is never modified during B it seems like aliasing wouldn't cause any problems.

Since restrict means nothing if no value in it is modified, would it be reasonable and possible for the compiler to issue a warning in cases like example1?

Nah, I'd just like to take a look at it, but you might be able to get someone else to use it on ARM compilers if you release it.

It should be alternating lines with red, black and blue not greys, it's to increase reading speed: http://www.beelinereader.com/

Aliasing information is one place the programmer can help the compiler. The 'restrict' keyword in C/C++ is a great example of this. Also information provided by 'const' can be very helpful for the compiler. While both of these aren't strictly hints because they limit what you can do and still get correct results, they do tell the compiler facts that would be otherwise difficult or impossible to prove.

In level 9 rank (among contacts and global) is shown, but percentile would be more interesting.

Here's how I did it: https://bitbucket.org/teoryn/image-approximation

For converting the polys to pixels I render it with OpenGL and then extract the resulting image. I use ppm for both input and output, they're just a plain text file, and any decent image editor can convert to or from them.

The faster version looks like it might not be numerically stable; if sum(l_quantity) is greater than the maximum value that can be represented it would overflow and give meaningless results. Given the arrays mentioned by the average function, it could also be maintaining a heap and adding the numbers from smallest to largest for more stability.

Naive fibonacci is a much more interesting example for memoize than factorial:

    fib = +lambda {|n| return 1 if n <= 1; fib[n-2] + fib[n-1]}

Q: What if there are multiple valid segmentations? A: Just return any valid segmentation if there is one.
