I'd argue that a neural net is "black-box" in the sense that nobody really can give a coherent answer to "what happens if I perturb/double/negate this parameter" where the parameter might be deep in some w

Yes, and based on the $0.15/kWh comment, about $450/hour of electricity. This is more in line with what I would have guessed for 220k cores.

I was about 10 years old and at a bonfire at a summer camp in Texas. It was dark when I was bitten, so I never saw the spider. It felt like there was something between a mosquito and a cockroach on my ankle that was hard to shake off. The b

I think I liked spiders before I got bit by a brown recluse. Now I like dead spiders.

What do you mean that it's "much easier to just pay people a decent wage"? Do you mean that it's much easier to convince companies to pay their employees more than they have to, or that it's much easier to pass high

So if you were running Uber, would you increase your prices to pay a more fair wage even if it makes you more expensive than competitors? Would you expect to stay in business if you offered a commodity like transport at 20% higher prices th

I give about 30% of my Lyft drivers a tip, and I'm glad Lyft includes the option in their app. I've occasionally wanted to tip an Uber driver but then not had cash on me. I don't think it's reasonable to expect ride shar

Agree with your point, but average latency isn't as simple as inverse of throughput, even on a serial processor. Imagine a process that takes in a request, sleeps for 10s, and then provides a response. If taking in 1 million req/s

Good to know about the JSON spec. The only JSON parser I used before jq was the Python stdlib parser. Python JSON correctly handles big integers, which lead to my (out of spec) expectations for jq to do the right thing.

There's something to be said to be familiar enough with the optimization that you can predict assembly that is not a direct translation of what you're writing. For instance, when writing a scalar-processing loop over a fixed lengt
