Small correction to this. There actually wasn't a library for JS we had to write that for ourselves.

Hi, here to answer question number 4. Short answer: Our configuration data is most similar to git. Any machine can be used as an administrative node via the WebUI or the CLI. It will make changes to the metadata which then get pushed to the

The elevator pitch is: "Mongo's ease of use without the gotchas." We have a nice simple to use query language and quick setup process. But things like analytic queries like map reduce don't lock up the entire database. Our product aims to n

Correct currently no secondary indices. Ranges on fields other than the primary key will require a full table scan. -Joe Doliner, engineer at RethinkDB

Well, Though the above code is not freeing up the memory allocated to ‘ptr’ but still this would not cause a memory leak as after the processing is done the program exits. Well this is always true, so I guess that means there's no such th

In what way does this trivialize birth control? The ideal of birth control as a technology would allow anyone to cheaply turn their ability to reproduce on or off with no side effects. It's no more concerned with unwilling partners than wil

No, read the comment you just responded to. I only did grading. It wasn't until I asked a friend of mine who was in the class what he thought of it and he responded: "Line numbers are a bitch" that I discovered what was going on. At which p

Yes, that they got poor instruction is my point. Furthermore more my point elaborates on why it was poor. Because they were taught many individual tricks and never how and when to search for new tricks.

Alright, I guess I'm not fully aware of all of Nano's features. And yes, my entire point is that it's much better to teach them to fish for tricks in various places rather than teaching them individual tricks. Also I was only a T.A. in this

I actually strongly disagree with the idea of an Electronic Literacy class, at least I disagree with it as a class which basically teaches people tricks like control-f that can save them time. Let me relay a story: In college I worked as a

No hashify is not really a hash function. Since a hash function takes large data to small data it is implicitly not invertible. Hashify's URLs obviously are.

A number of restaurants have successfully integrated games into meals. The example that comes most readily to mind is Buffalo Wild Wings in which you can play trivia games against other people in the restaurant. Granted I don't it would be

This chapter actually has a much cooler implementation of delta debugging that what has been discussed here. We're generally thinking of delta debugging in which we take the changes to the source as the search space and use some form of bin

I find this to be quite acceptable. Reddit is constantly facing the question of what exactly a downvote is. (There was even a very funny comic on the topic recently.) Everyone sees downvote as the opposite of upvote, which is understandable

I doubt that the interviewer mentioned the prime number solution due to insufficient cleverness in the original solution. The answered O(n+m) solution actually contains flaws beyond its lack of cleverness. 1) there's no good reason to use a

This article has popped up a few times (I think it's been on HN before) and I've read it each time with increasing disgust. There's a pervasive attitude amoung attendees of elite universities of feigned modesty, mostly it's fairly innocuous

I'm a very recent graduate and I enjoy using C. C was used in almost every class I took in college. Normally these days I use C++ but I still tend to default to Cesque solutions. It's nice having a language that you can fit in your head all

As someone who does a lot of interviewing at RethinkDB I agree that these numbers are in many ways bullshit. Firstly they're pretty clearly hyperbolic (I think we all knew that already). However I think they also tend to be the result of a

While this arbitrage is fun and makes you feel very clever (as arbitrage almost always does). I'm not sure why this is framed as "Confessions." The author pretends this is some affront to books but books are one of the earliest mass produce

I'm a Vim user and here are my 2 cents on the matter. Vim has a lot of keyboard tricks because there's a keyboard shortcut for almost everything. Don't worry about those right now. Here's how I would suggest you learn Vim: You already know

So do they just figure they'll ride the gravy train until it completely breaks down? Do they acknowledge this is a problem or do they just think it's fine?

Is there a setting to make it talk back to you in TeX. If so a really neat IDE could allow you to write an equation in TeX and then query Alpha and have it solve the equation in the IDE for you.
