| - | What is the best way to contribute code? Should it just be placed here or should a seperate page be created?
| + | |
| | | | |
| - | Good question, I had intended to leave a lot of that type of decision up to whoever posted something but since this is going to be a community page it might be better to keep it less cluttered so I will suggest making a brief statement here about the code and a link to the page where the actual code lives. The discussion tab [[Talk:Code Vault]] can be used for comments rather than making further clutter here. If you haven't gotten the copyright holder's permission to use the code the link should be to the original source.

| - | == [http://www.cs.ucr.edu/~nsoracco/py/mailScrub.html Email List Filter] == | + | ==[[user: Charles Wyble| Charles Wyble]]== |
| - | This is a python script designed to filter out bad emails from a mailing list. The script is written as an excuse to learn python. It's designed to have both offline filtering (via regular expressions) and online filtering that uses MX lookups and SMTP server testing. Lots of example code in here can be lifted for other apps.

| - | == Access Database to HTML == | + | |
| - | I have written a bash script that converts Access databases to HTML.

| - | == Process Substitution (or, how to do more with less effort) ==
| + | |
| - | [[Process Substitution]] is a good way to do things in a single line of script or at the command line, that would otherwise take extra work like writing to temp files.
| + | |
| - | | + | |
| - | == Python File Slicing == | + | |
| - | [[pyFileSlice]] is a simple utility that will chop out a section of a file that has common starting and ending tags. Pulling out the page referrers section in an [http://awstats.sf.net Awstats] data file for further analysis prompted this little bit of research. After trying 3 methods (one involving regex pattern checking over each element in a list, one involving startswith(), and one that uses startswith() and doesn't read the file all at once) the one presented here works the fastest with the least amount of memory used.

| - | == Generate a report on an Email Dictionary Attack ==
| + | |
| - | This is just some Bourne shell script I whipped up while trying to learn more about a dictionary attack hitting my mail server. Messages not delivered to a real user are dropped into /var/spool/mail/bounce in maildir format. Change the numbers following seq to the start and finish messages desired to check. I'm just posting this here primarily as a scrapbook, and for educational purposes.

| - | ==Shell script to enter low power mode on boot==
| + | |
| - | A simple little snippet to add to rc.local (or your distribution's equivalent of post-SYSV start up script) that will help conserve power when booting up in battery mode.

| - | # Haxx to lower power usage when booting up on battery.
