When run as a cgi script, this will print the client's IP address.

import cgi
import os

print "Content-type: text/html"
print ""

print cgi.escape(os.environ["REMOTE_ADDR"])

I used the following sox audio editor settings to do dynamic compression on voice.

The script expands a zip or rar archive of images, makes thumbnails, and compiles the thumbnails into a single JPG to represent what's in the archive. Requires ImageMagick.

Code:

#!/bin/sh
# GALLERATE: Turn a zip of images into a gallery.
# From Jason Scott. http://ascii.textfiles.com/archives/000137.html
if [ -f "$1" ]
   then
   rm -rf .galleryworld
   echo "[%] Preparting to squat out $1...."
   mkdir .galleryworld
   cd .galleryworld
   unzip -j "../$1"
   unrar e -ep "../$1"
   echo "[%] WHY DOES IT HURT!!!!"
   montage +frame +shadow +label -tile 7 *.JPG *.GIF *.gif *.jpg *.bmp *.png *.PNG *.BMP "../$1.jpg"
   cd ..
   rm -rf .galleryworld
   ls -l "$1.jpg"
  else
  echo "No such file, assmaster."
fi

Usage:

GALLERATE [file]

where [file] is the zip or rar archive of images to be processed.

Code:

Put the following in a file named url_scrape.py.

#!/usr/bin/env python
'''Prints a list of URLs that are found in standard input.

It will only find URLs between quotes ("" or '') and starting with http://
'''

import re
import sys

# Pattern for fully-qualified URLs:
url_pattern = re.compile('''["']http://[^+]*?['"]''')

# build list of all URLs found in standard input
s = sys.stdin.read()
all = url_pattern.findall(s)

# output all the URLs
for i in all:
    print i.strip('"').strip("'")

Example Usage:

wget -O - http://madphilosopher.ca/ | ./url_scrape.py | sort | uniq

The FreeBSD ports collection is a skelton of installable software on a local FreeBSD machine. This small utility lets you scan the collection by category, to find out what software is available in that category. Call the script portinfo.py.

A deeper explanation of the script can be found here.

"""Scans a directory under /usr/ports/ and gives the portname and comment for each port found."""

import os
import os.path
import sys

def findmakefiles(curdir):
    '''goes one level deep under curdir to find and act on the Makefiles.'''

    for name in os.listdir(curdir):
        pathname =  os.path.join(curdir,  name, 'Makefile')  # COMMENTs are found in the Makefiles
        if os.path.isfile(pathname):
            processmakefile(name, pathname)

def processmakefile(name, pathname):
    '''grabs the port's COMMENT from the Makefile.'''
    f = open(pathname)
    data = f.readlines()
    for line in data:
        if line[0:7] == 'COMMENT':
            try:
                comment = line.strip().split('\t')[1]   # most COMMENTs are tab delimited
            except:
                comment = line.strip()                  # some are not, so just print the whole line
            print "%-15s  %s" % (name, comment)

    f.close()

def usage():
    print 'Usage: portinfo.py /usr/ports/[category]'
    sys.exit(1)

The following will look up a word on dictionary.com from the command line, where $1 is the word you want to look up, entered in as a parameter on the command line. (Lynx is a text-based browser that handles the html-to-text conversion for us.)
