I hate these articles that jump straight into some complex solution without stating the problem clearly... If the problem really is to send a real number using a single bit (and some shared randomness) then clearly that’s just impossible. Next!

some of the comments on this article are so embarrassing. It's just a short and clearly written article on a pretty simple and fundamental type of problem in information theory. Similar ideas are the basis for the systems we use in data compression and transmission and error correction among other things.

Maybe better to think for a few seconds before dismissing the problem as pointless and claiming to hate it.

The table's the point cloud. I guess if you want to be really pedantic about grammar then I should point out that a set of one item is still a set. :-)

True - I misread your post. Your first post was intriguing but the second was dismissive. Surely there's more to be said than data sets are point clouds? Images are points in R^N too, right?

A row in a table of data is an point in R^n. I'm not sure how much there is to write about it other than to say, that's a point cloud.

No, that's a point.

The hardware requirements wrt memory to run a validator node are just insane https://docs.solana.com/running-validator/validator-reqs

Remember when people claimed that the bitcoin block size couldn't be increased because we would sacrifice decentralization? Well look where we are now...

This must be some new kind of marketing from big-leetcode.

> It used to be like this: You spend A LOT of money for really nice headphones and use them (potentially) your lifetime. Or hand it down to your kids as your hearing gets worse.

I think this is a fantasy. How many decades have there been high-quality headphones for this to be a thing that you think is supposedly the traditional way to do it? Did your parents hand you down their headphones? Surely your grandparents didn't hand down theirs? So it maybe happened once? For a few people?

asdf3331 · 5 years ago

I bought my headphones (Audio Technica ATH-AD700s) when I was in school. I still use them now and they sound just as good as anything else you could buy.

Not quite generational inheritance but I can't think of anything else I bought back then that I still use. It's pretty satisfying when I think about it.

Life can be defined in terms of entropy. The 2nd Law of Thermodynamics says it's always increasing, and it was once lower. The law only applies for closed systems, so if we generalize to any system sometimes entropy increases. Life is a system that consumes low entropy and transforms into high entropy [negative entropy]. From light to other life, life is consuming lower forms of entropy to then use it in its information processing systems.

Schrodinger wrote about life from this perspective in an article also called "What is life?"

I thought it was pretty good.

Remember, if you are in the US at least, and someone tells you they aren't ok, and you recommend a crisis line, and they mention anything regarding suicide, they are very likely going to be extracted from their living situation by physical force and end up incarcerated against their will, at very high expense to themselves, potentially in a way that could lose them their current housing or employment.

If their life was going poorly before that, it sure won't be better after.

The record of this could follow you around for life as well.

I understand this is considered conventional wisdom to recommend these help lines but I really think you should rethink that.

asdf3331 · 5 years ago

In addition to all those negatives, they don't do much help either. As if a phone call to a stranger will make any difference to someone who's contemplating suicide.
