Underscore.js implementation of Cartesian Product (without any mutable variable). @see: http://stackoverflow.com/questions/12303989/cartesian-product-of-multiple-arrays-in-javascript
function cartesianProductOf() {
return _.reduce(arguments, function(a, b) {
return _.flatten(_.map(a, function(x) {
return _.map(b, function(y) {
return x.concat([y]);
});
}), true);

JS: AngularJS Directive Attribute Binding Explanation

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

  1. Raw Attribute Strings

    <div my-directive="some string" another-param="another string"></div>

List mongodb collections in descending order of size. Helpful for finding largest collections. First number is "size," second is "storageSize."
var collectionNames = db.getCollectionNames(), stats = [];
collectionNames.forEach(function (n) { stats.push(db[n].stats()); });
stats = stats.sort(function(a, b) { return b['size'] - a['size']; });
for (var c in stats) { print(stats[c]['ns'] + ": " + stats[c]['size'] + " (" + stats[c]['storageSize'] + ")"); }

Quick example of creating, using and deleting a temp file in python
import os
import tempfile
file_descriptor, file_path = tempfile.mkstemp(suffix='.tmp')
# You can convert the low level file_descriptor to a normal open file using fdopen
with os.fdopen(file_descriptor, 'w') as open_file:
open_file.write('hello')

a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Go RPC over TLS.You have to create the following keys: certs/client.crt, certs/client.key, certs/server.crt, certs/server.key. client.crt and server.crt should be signed with ca.crt, which should be concatenated to both client.crt and server.crt. It's easier to do with easy-rsa: http://openvpn.net/index.php/open-source/documentation/howto.html#pki
package main
import (
"crypto/tls"
"crypto/x509"
"log"
"net/rpc"
)
func main() {
