This makes sense if you only speak English, but a lot of people in this forum speak at least two languages.

You might be thinking of the load average, not the cpu consumption of a particular process as reported, by, say, top or ps. The article is about the latter kind of tool.

Clever idea. How do I get my harvest once it’s ready? Does someone have to harvest the plants for me and mail them to me?

You can speed up the numpy code by 2x by replacing the line: M_old = np.exp(1j*k*(np.tile(a,(N,1))**2 + np.tile(a.reshape(N,1),(1,N))**2)) with a_squared = a ** 2 M = np.exp(1j * k * (a_squared[:, None] + a_squared[None,

Ok, maybe not the arithmetic code (or huffman), but I was thinking you'd at least invert the DCT on GPU.

Are all stack-based languages concatenative? What would it take for a stack language to not be concatenative?

If the goal is to save memory, you can go farther than this. You could store the JPEG in RAM, compressed, and have the GPU decompress & shade. Each of the DCT blocks can be converted massively parallely on GPU.

Unpopular opinion: This policy lets managers take bigger hiring risks. They can take a chance on diamonds-in-the-rough without feeling embarrassed for it. Without this, managers are incentivized to just "hire the best", instead of

you're extolling energy density (energy per unit volume) but your example is about power delivery (energy per unit time). the former is the real progress. the latter just needs low internal resistance, which is a thing we've had.
