I have been trying to show pretty code snippets on blogspot.com/blogger.com. I found for larger files github.com displays code nicely but not very handy for short inline examples. Today I discovered prettify by google
This post describes setting up code.google prettify on blogger.com
Originally explained here:

Include this before the head tag in the blogger template.
I have made a modified version of the css file suitable for displaying code on darkbackgrounds, I use this instead:
Then change the body tag to:
Then use the prettyprint class when using pre tags around code:

Scite bash script config
in Scite the config for bash/shell scripts are handled by the perl.properties by default.
I believe this is the section of the config file which applies it to .sh file by default.
file.patterns.perl=*.pl;*.pm;*.cgi;*.pod
file.patterns.bash=*.sh;*.bsh;configure
shbang.perl=pl
shbang.sh=sh
filter.perl=Perl (pl pm)|$(file.patterns.perl)|
filter.bash=Bash (sh bsh)|$(file.patterns.bash)|
lexer.$(file.patterns.perl)=perl
lexer.$(file.patterns.bash)=bash

Ruby Shoes, Get full path of current application
After reading this post [1] I though that [2] would return the full path, as the url suggest it is only a relative path. For Ruby scripts executing under Shoes the current dir can change so it is always best to refer to a full path. The short script at [3] should give just that.
[1] http://stackoverflow.com/questions/757455/relative-file-paths
[2] File.dirname($PROGRAM_NAME)
[3]:

modulepath = File.expand_path($PROGRAM_NAME)
modulepath = $modulepath.gsub($PROGRAM_NAME,"")
return modulepath

New file and directory permissions on unix
Unix and Linux based sytems define default file permissions with umask.
$ man umask
To see you current permissions just run:
$ umask
>0022
For a more user friendly format:
$ umask -S
>u=rwx,g=rx,o=rx
Person is User, Group and Other.
Properties are Read, Write and eXecute.
umask subtracts from the normal properties set by chmod.
Folder and file are the same, except files will never be set executable by default.
(the -- are just to allign the tables, the numbers are the decimal equivalent for a 1 set in that position)
--421,--421,--421
u=rwx,g=rwx,o=rwx
Say you (User) want full access to a file but not allow Group or Other access.
you want:
--421,--000,-000 ie 700
The mask would be
--000,--421,--421 => 077
to set this just run (and may be add to your ~/.bashrc file) :
$ umask 077
You (User) want full access, Group has read and execute and Other none
--421,--401,--000 ie 750
the mask would be:
--000,--020,--421 => $ umask 027
You (User) have full access and Group and other have read and execute.
--421,--401,--401 ie 755
mask would be:
--000,--020,--020 => $ umask 022
NB:
Q) How do i set umask to make files executable by default?
A) You can not create exectuable file by default using umask, it is thought to be a security issue.
