There are plenty of compelling arguments against excessive running: 1) It is destructive to your joints and tendons. Injury rates are very high among runners. 2) It is stressful, resulting in chronically elevated cortisol levels. 3) It is t

This doesn't sound like an efficient way for executives to spend their time.

But isn't each field a multiple of the word size on both 32 and 64-bit platforms?

With GCC, both those structs seem to have a size of 416 bytes. Can you elaborate on what you meant?

What if you always recurse into the smaller half, and use tail-recursion/looping to process the rest? Doesn't that keep the space usage bounded to O(log(n))?

Note that this uses Markov chain Monte Carlo (MCMC) sampling rather than the Monte Carlo tree search (MCTS) of AlphaGo, although the latter might also be interesting to try. I suppose one disadvantage of naive MCTS is that if it made a supo

Why not just use time-domain convolutions?

The demos are still neat, and some of the ideas are being used in AV1.

Anyone who likes this would probably also enjoy the Daala technology demos at https://xiph.org/daala/ for a little taste of some newer, and more experimental, techniques in video compression.

Assuming this refers to the Apollo Lunar Module, landing on the moon was an engineering challenge based on known science, and it still cost an obscene amount of money for questionable benefit. This is a relatively small sum being spent on a

Little known fact: pure nicotine is hardly addictive. The Mono-amine oxidase inhibitors in tobacco really ramp up its addictive potential.

This seems like cargo-cultism. How is doing something redundant and potentially harmful just to conform to a general guideline any cleaner than exercising judgement?

You may have noticed that whales are big.

For a blue whale I get around 5000kcal; I'm not sure if this is a little or a lot. Of course, with the various inefficiencies involved the whale would need to eat a few times more than this to break even.

I think the best way to understand recursion is in terms of induction. If someone gave you the solution to your problem for different inputs, could you compose them together to solve the problem for your current input? Then you just have to

This is not really true any more. Computers will still play at a superhuman level if you disable the opening book.

So we should be willing to lie if it makes a better story?

Setting the hidden layer activation function to value => value >= 0 ? value : 0.5 * value; seems to improve convergence a lot.

And strings can also be long.

by eutectic 10y ago
Just store a bit (for a set) at each internal node, denoting whether a string ends there. For a map you also need a value pointer. Hashing keys is also easy: add a pointer to a linked list of key-value pairs to each leaf node. To save space

If you have a column of text labels and only a few format as dates, they are very unlikely to be dates. Excel should be smart enough to know this.

Does human learning have anything to do with consciousness?

I wonder how much of the process could be automated.

by eutectic 10y ago
Agreed. And for the record, I also like imperative languages (e.g. C), where appropriate.

Except that there is a real advantage to using pure functional programming; being able to easily prove theorems about your code and understand different components in isolation. There is a reason why the majority of proof assistants are imp
