That makes sense. I hadn't considered academia. I was thinking that if there is a business need for mapreduce, then the solution is probably going to become long-term infrastructure, in which case the cost of setting up hadoop can be amor

What do people use this sort of thing for? The example is neat, but it's trivial and would take 4 lines of non-mapreduce code. What sorts of problems do people have that are big enough to need mapreduce? It seems to me that problems bi

I see, and I agree, both terms are overly broad.

They aren't diametrically opposed. They are different aspects of the same thing. At the end of the day, it's all just tables. NoSQL gives you one table and all sorts of scalability and robustness and tools for working with that table. RD

I would agree that MapReduce and NoSQL are different things, but so are NoSQL and AJAX. I've always thought of NoSQL as a class of durable, distributed lookup tables, and the style of programming which uses such tools as a primary data stor

Programmer and Sysadmin were either very lucky, or not working on anything important, or else they would have been fired or gone out of business. You can't just add caching and magically expect things to work. You have to think hard about

It would bend or stretch before it snapped. Nearly all, if not absolutely all, materials that you might want to build a see-saw from will deform before they snap. Maybe it won't deform much, but that ok, and is enough to transmit a push f

What is the technical definition of "information"? I know what information is in a colloquial sense, and I know something about it's technical definition in the field of computer science, but I don't know what physicists mean when they use

Agreed, I wasn't complaining, I was just pointing out a minor inaccuracy in the title. It's very impressive and doesn't need to be oversold.

It's not quite fully working. Either that, or I just can't figure out how to castle. Even so, it's very impressive.

Capitalism doesn't have a purpose any more than, say, evolution. Capitalism is, perhaps, best thought of as a description of how the world works, in particular, how wealth is created. It has nothing to say about why wealth is created any

This assumes that you are going to the trouble of initializing your skip table once and re-using it. Now you have state to maintain beyond the life of the function call, or else your performance is slower than brute-force. That, in additi

map/reduce is a very simple, very general idea. It is also Google's and Hadoop's specific implementations with lots of bells and whistles. It's also everything in between. This implementation has more than the minimum two necessary featu

Rights are inalienable, but their recognition by those in power is delicate and must be protected everywhere -- even when it doesn't seem like it matters. Besides, how hard would it be to implement a reputation system instead of censorship?

It's not ergonomic, which undoes the rsi advantages of dvorak. It's a weird physical layout, which undoes the "it's standard" advantage of a qwerty switch. It won't save your wrists and it won't let normal people type on it without effort

by adamtj 16y ago
I probably wouldn't if I were you. I switched to dvorak in college. My wrists started hurting while finishing a major project. I immediately bought an ergonomic keyboard and switched to dvorak. My typing speed was drastically reduced.

I think he was suggesting that you find the ATR on real-world production webservers, which has nothing to do with your test and would not confound it. Maybe in practice nobody sees an ATR > 30%, in which case your test, if correct, is

As I see it, its easier to mix any subset of procedural, oop, or functional code than it is to mix either of those with relational queries. Operating on query results WITH Ruby is easy. Writing relational queries AS ruby is a big impedanc

It seems to me to be a pointless, hacky kludge. As with every other ORM, the abstraction will leak as soon as you do anything interesting. Even if it doesn't leak, there is mental stress involved with convincing yourself that it won't. A

Think of it like this. Zed is combining Apache's nonstandard configuration language with it's internal runtime representation of such. He's doing it in a way that's standard and manipulable at runtime. So changes to the runtime configura
