I agree that ruby is slow, and I actually recommended Java, but ruby execution is not going to be the bottleneck for a webapp, the database is.

For a 'large' webapp I would honestly go with Java. A good stack is Jetty for the http server, and Jersey/JAX-RS for the web framework. The JVM is unbeatable, and you will have an easy time onboarding people since everyone knows Java. It's

Is this limited to 2d and 3d space or can it handle n-dimensions?

Curious to hear which Java DI frameworks you dislike. I've used Google Guice before on a large project and I found it to be great: it doesn't get in your way and it makes your code a lot more modular and testable.

Two recent projects come to mind, one where I was working on a program to draw and manipulate points in 2d space where I used rotation matrices, and another where I was testing the graphing routines in a monitoring service by sending load i

Start with these topics. Work your way through them, and make sure you understand everything you have read so far before progressing. Do the exercises, or it will be a waste of time. 0) Algebra, Trigonometry, Calculus Make sure you have a d

While mostly agree with your criticism of NKS, in Wolfram's defense, I have personally found Mathematica to be a joy to use. Under its unfortunate syntax, there's a great functional programming language there. While you can do many of the

He still has much, much more tied up in facebook. The fact that he's diversifying his holdings shouldn't be held against him; any reasonable person would do the same to hedge against a possible decline of the entire technology sector in the

Yes, the munching square picture is the same because the hamming distance of two binary numbers is their XOR. As to why it looks similar to the visualization in the article, your hamming distance picture is essentially the multiplication ta

Yes, but this is true regardless of the irreducible polynomial used to form the field. My question is why that specific polynomial was chosen; was it an arbitrary choice or was there some reason?

Cool article overall, especially since it was an actual CS related application of the abstract algebra class I took this semester. Also, is there any reason in particular why that particular polynomial was chosen for AES?

Curious to hear more about your complaints with PyMongo. Care to share any specifics?

This is in the works already with Google's PNaCl. I believe the bytecode format is based on LLVM IR.

Computer Organization and Design. The other book goes further in to detail about the hardware and is intended for an EE-oriented audience.

I actually have the pleasure of taking a course with Patterson this semester. He's a great lecturer and he manages to keep the (sometimes very dry) material very interesting.

Personally, I think that the latest edition has a lot of valuable material on parallelism and GPU programming. It's not strictly necessary for what he was asking, but its good stuff to know nonetheless.

First read K&R C and get comfortable writing C programs. Then pick up the latest edition of Patterson & Hennessy and learn the MIPS ISA. It's a very simple instruction set that avoids most of the pedagogical distractions imposed by

"They wrote their own BSON implementation which is 10-15 times faster than the one you can download." Curious to hear more about that one. If true, I hope they open source it, because that could potentially make MongoDB a lot faster for eve

The network effects of Draw Something's user base add immense value. Think FB vs. G+. If Zynga had made their own Pictionary game, it would have been a graveyard.

The amortized CAPEX (cost of building the data center) is still greater than the OPEX (cost of keeping it running). If Google can find cheap land and labor, heat might be irrelevant.

I'd wager that many if not most corporate internal networks are vulnerable to ARP poisoning. A little computer hooked up to the network via ethernet is all one would need to launch such an attack, and https is vulnerable since many users ha
