Why does direction of index matter in MongoDB?
...
MongoDB concatenates the compound key in some way and uses it as the key in a BTree.

How to check if an option is selected?
...).is(':selected')) ...
The non jQuery (arguably best practice) way to do it would be:

var argv = require('yargs').argv,
gulpif = require('gulp-if'),
rename = require('gulp-rename'),
uglify = require('gulp-ugli...
Java compile speed vs Scala compile speed
I've been programming in Scala for a while and I like it but one thing I'm annoyed by is the time it takes to compile programs. It's seems like a small thing but with Java I could make small changes to my program, click the run button in netbeans, and BOOM, it's running, and over time compiling in ...
Where can I find and submit bug reports on Google's Chrome browser?
It will be important for developers wanting to develop for the chrome browser to be able to review existing bugs (to avoid too much pulling-out of hair), and to add new ones (to improve the thing). Yet I can't seem to find the bug tracking for this project. It is open source, right?
