As a programmer/web-designer I dip into a diverse range of programming languages and frameworks. I often find that I get locked into a specific coding grammar/syntax and that it is then difficult to switch to a new one. This is when I find the following cheat sheets invaluable (and indeed comforting).

ARPWatch/Log Watcher — A tool that monitors your network activity and keeps a record of IP/Mac address pairings and firewall logs. It will give a warning when it notices any suspicious activity, like any changes in Mac address or any connection attempt to the firewall. [via]

I must confess that I am an addict. I have become addicted to creating computer-generated images. Having recently posted about Processing and Oxidizer, I have found another image generator called “Context Free.”

Context Free “is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.”

Creating images with the software is a piece of cake. One can download from a gallery of “grammar” files or create your own scripts. Downloaded scripts can have their output modified by entering a three-character code into the Context Free application, leading to millions of permutations of the work.

It’s a fascinating program to play around with and some of the output is simply stunning.

Best of all — the software is free, open-source and is available for Windows, OS X and various flavours of Unix.

A simple console shell which allows you to run SQL queries against an Apache logfile, something that can be very useful - especially at getting information which is not easily available via static logfile analysers. [via]
