You don't have to use sorting networks; to differentiate (or get a subgradient, anyway) a sorted list you just pass the derivative back to the original index, so you can use any sorting algorithm as long as you keep track of the permut

I really love the auction algorithm for maximum-weight matching, especially the variant where bidders bid the price that makes them indifferent with their second-best option. It's so simple and elegant.

Urea doesn't smell like anything much. Leave it long enough and it breaks down to make ammonia, which does.

The poisson distribution is quite-light tailed. With a poisson distribution, the probability of completing the task per unit time is constant. Real world tasks are likely to take longer if they have already gone on for longer; maybe a Paret

We live in a world in which it is easier to collect 'sin taxes' than to tax the rich. The wealthy have resources to fight any attempt to collect a fair, let alone progressive, share of their earnings. And yet, it might be rational

I already appreciate bats for how awesome they are! They're the fastest (and only flying) mammals. Surely that should be enough. If I were a bat, would it be rational to harbour animosity about any of the myriad diseases spread by huma

Water can dissolve KNO3, and ethanol can dissolve sulfir (slightly) and tar from the charcoal, so maybe it helped create a more intimate mix? It would also have kept down sparks and reduced the chance of ignition while mixing and grinding.

I had good success using a DAWG for pruning, and letter-wise (rather than word-wise) branching, picking the letter with fewest options. If you want to get fancy, you can use back-jumping instead of backtracking.

I wonder how well gpt-3 + search would perform as a crossword-solving agent. I guess the tokenization might be tricky to deal with.

Hydrogen peroxide is a very aggressive oxidizer compared to molecular oxygen and will break down molecules instead of just adding to them.

I'm also a Dvorak user with a randomly generated password, but I memorized it by coming up with an approximate pronunciation so it's still firmly lodged in my brain.

I meant how effectively can your body use it as a source of energy. I think the conversion efficiency is much lower than e.g. sugar or fat.

I would try an n-gram model with dynamic programming. e.g. logp(_, "") = 0 logp(word0, text) = max(logp_bigram(word0, word1) + logp(word1, rest) for word1, rest in prefix_words(text))
