This is an example of a Bash shell script used to loop through a list to compare to text strings found in logs. The script is used to detect and block attacks on a web site.

In this second and final part I'll demonstrate some of the loop-specific tools I've found in Ardour, Reaper, and Audacity. Tutorials and links to project demos are included, so warm up your headphones and let's get loopy.

Smasher is a cross-platform audio loop slicer designed to create sliced loops from WAV, MP3, FLAC or AIFF files in seconds without a sequencer.

There are network subnets that have been taken over by Spammers and run by bots. These networks are recorded and documented by Spamhaus and provide you a quick way to modify your firewall to eliminate these know blocks of Spam.
