As you say Google were one of the pioneers of the Chaos Monkey concept; they simply run at a scale where the Chaos Monkey occurs through normal failure rates. For sufficiently large MapReduce jobs you can expect one of the compute nodes to

I agree whole heartedly. When you commit you're free to do drastic restructuring, leading to better thought out code. In the worst case you can revert to an earlier stable point but I find that's almost never needed. This is also a situatio

Very good point regarding the UI. I find it quite annoying when people complain about Blender's UI. VIM's UI is also not "new user" friendly but VIM's UI itself is very powerful. Blender and VIM are made for speed with familiarity.

Emscripten, given the recent advancements in Javascript interpreters, holds immense promise. There is a problem however: the size of the Javascript "executables". As the size of their executables are already competitive with their C/C++ cou

Your code only needs to be threadsafe if you wish to enable the concurrent flag, otherwise your code will happily run as it had before. I just thought it's important to note that they're not forcing you to push a code update unless you want

Sounds like you need to get a better internship =] Mind you, if it pays well and you have enough spare time to pursue your own interests then it might not be such a bad thing overall!

It depends on the type of technical interview. If it's the sort of drivel that HR throws at coders then the less in the world the better. There are circumstances where this would be beneficial however. For my Google internship interview I s

The point is Redis is beginning to move away from being just an in-memory database. See my other comment for a more detailed answer as to the use case. Persistent caches are an important commodity for many websites. For some services trying

It's similar to a per user log - a user has an entry from time X, time Y and so on and you're likely only interested in the last N entries. Let's say for this case that N = 20. This is a near perfect use case for Redis lists. I say near per

I love Redis a great deal but I can't wait for the persistence issues to be worked out. The fact that they're restricting the working memory set to 24GB on a 32GB machine purely to prevent death by SAVE or BGSAVE is quite concerning. For my

Good catch, thank you. I also noticed that I'd stated the storage cost as $1/GB whilst it's actually $10/GB (specifically $10.24/GB or $0.01 per megabyte per month) which means that S3 is really far ahead if your site has any substantial am

Git seems to be torn between centralization and distribution. For large projects you always seem to fall back to the SVN style single repository even if Git allows effortless decentralization. There are projects like Google's Gerrit [1] whi
