One nice example of deep insight is the Ramanujan Tau sequence, which comes from expanding out the product (1-q) (1-q^2) (1-q^3) all to the 24th power and multiplied by q, as q-24q^2+252q^3-... Ramanujan noticed that the coefficients a_n ha

You could say that about any field that one is unfamiliar with. Heck, the most basic art concepts could seem like so to a blind man. Mathematicians have worked for ages on simplifying the concepts so every term is there because it helps a

You have two functions both of which grow to infinity, one of which is much better understood than the other. It turns out that if you subtract the two functions, they balance out perfectly so you end up with something converging to 4 inst

RIM looks like a great investment. As mentioned in this thread, they have very long term contracts so they won't die anytime soon, and they Are trading at such a ridiculously low premium that if they don't die they're bound to go up by a f

King James II of England, when he saw the restored and expanded St. Paul's Cathedral, called it "amusing, awful and artificial." The architect, Sir Christopher Wren, was not offended. On the contrary, he was flattered. The king did not mean

Right now we are waiting for his corrected paper, as the current one contradicts some known number theoretic results. Mochizuki put uP an amazing amount of scaffolding and invented a new area with new abstractions. People who I trust claim

Does anyone know if filepicker.io has plans to support this? Currently file uploading in mobile safari is rather underwhelming

I think that works if you follow a link from another app, but not if it is a popup from safari? Or maybe they changed this in ios 5

Very true, this is especially a bugbear of mine when browsing on iPhone. All too often I have eight tabs open that I'm meaning to get back to. Then I click on a link (or accidentally click an ad) and my heart lurches as the link opens a n

Very true. One of my first forays into Haskell came during the Google Code Jam, after seeing how short and elegant Reid Barton's solutions where. I solved the problems, but the programs were horribly slow, so I checked how Reid got around

Umm, assuming the github repo is what they actually use (i assume so given how often it is committed to) there are two tables per object . Reddit_thing_link, reddit_data_link, reddit_rel_thing_savehide, etc etc

They in an ad hoc way turned postgres into a key-value store, but in reality they have Cassandra running as a "permacache" in front of it and, in practice, everything really just hits Cassandra. It looks like postgres could at some point b

Technically, for Perl you can use $ for regex backreferences. I don't remember which one is preferred, but I remember it frowning upon one of them.

Just a nitpick, the hot coffee case wasn't as frivolous as it sounds. McDonalds had been serving its coffee unreasonably hot (190F instead of 140F, which causes third degree burns almost instantly) even though they had previously been warn

It's not really about "like" or "not like" but fundamental economics and mathematics: things that grow behave differently then things that don't, and are worth more. Suppose FB found a way to consistently make 1B a year, give it to the in

There seems to be a strong tendency to assume that erveyone is like the speaker. It's especially funny when friends of mine mention something like that (everyone is non-religious everyone is super liberal) not yet realizing that I don't f

Thanks, I'll check that out. How does it compare to johnny-cache, which is what I've been using? It has the advantage for me that I only need to include it in settings.py, and I don't need to manually plug in a manager into my models, so

One option is to use the debug_toolbar package. You can set it up to display only when testing or only when an admin is logged in, and it will give you a convenient bar on the right side that shows exactly how long everything took, along w

I agree that the typical person can be a sheep, however: * the church callout is unnecessary, it can be a type of self-analysis * Alcohol is not toxic and in reasonable quantities does not have a purely deleterious effect. * When needing to

I had a similar issue with my Django project on Heroku. My site performance went down once I enabled memcache, almost entirely due to latency (going up to 100ms at times). This is one of the reasons why I ended up moving off of Heroku and

With a reserved instance, RDS starts with $20/month for the small, $92/month for the large, and it's easy to change the size as the need arises. Heroku Postgres starts at $200/month, which is more than I'd want to pay for an early-stage pro

Is there a good inexpensive hosting option for postgres aside from just running it yourself? Sort of like RDS on Amazon? Alternatively a DBaaS host for postgres?

I feel much more comfortable investing in a few companies that I feel are strong than investing in a mutual fund that will roughly end up tracking the market as a whole, and invariably ending up with a dangerous bet on the market going up.

I was at this event and it was quite an interesting way to see what kinds of ideas people are working on and what kind of help they need. There were 50 or so elevator pitches and a chance to speak with the presenters afterwards (which was

This is kind of a dealbreaker here. Especially since the chat in Google+ is indeed set to not show the Hacker News circle, but my chat in gmail is still showing everybody! And there's no visible setting to change that outside of Google+
