pypad - the python notepad web server

The plan is to take this simple python script and expand on it's note taking features with a GUI, console, and command line front end and additional storage options including a tiddlywiki style of appending the data store to the script.

The web server will eventually be an option rather than integral.

I will fork this into a micro framework and also fork it into a python eval type remote or local shell. Maybe even a REPL embedded in a web page.

Yikes backslash zero on wordpress.com

I started a new blog at wordpress.com, One Liner Code. I was reviewing my posts when I realized that my sed example didn't make sense to me. I didn't understand how I could have messed up such a simple example in the language that most easily lends itself to one liners. I thought I had double checked all of my examples and made sure they were running right. Turns out the html code looked fine. There was a preprocessor stepping in between me and my sed Hello World post. It was turning my backslash zero into a null.

I whipped out my handy dandy php evaluator and encountered failure using the htmlentities() string function. php wouldn't give me the htmlentity code for characters that didn't need them. I decided to switch it up and get the charactor code using a ruby one liner:

ruby -e '"0".each_byte {|i| p i}'

I could have also used a php one liner like this:

php -r 'echo ord("0")."\n";'

The quick fix \0 allowed the post preprocessor to accept the backslash zero and turn it into the correct character representation.
