OS X bash script to download entire picasaweb albums

Jason Lancaster — Mon, 18 Feb 2008 18:55:34 +0000

I found this great tool to download an entire picasaweb album except it didn’t work in OS X. After a quick search on a couple of man pages I found the difference when using OS X’s mktemp and fixed things. Now I can easily grab my favorite albums from friends and family and load them into iPhoto. What a huge time-saver!

PHP random password generator, randomPassword.php

I wanted to be able to control the strings a random password generator used and couldn’t find anything that let me use only the strings I specified. While it might not be completly random, I’m not a big fan of having []‘s or / or ? or any other ugly characters. I just like having the abc/ABC/123/!@# combinations.

Proper method for unlimited form inputs in a user interface

You probably don’t notice how counterintuitive some forms are, but in one of my new projects I needed a method to properly maintain an unlimited amount of relational data in a html user interface. I couldn’t find any tutorials or examples that properly managed (at least in my mind!) an unlimited amount of data so I created my own.

There’s very little involved to accomplish this. No funky php — just a little bit of javascript concatenation. I’d like to prevent the data from having to be hard-coded in the javascript function but I can’t come up with a method that prevents it for now.

Working example and howto.
