Just to get started on the wrong foot: "sometimes Arduino is the wrong choice." Depending on what you're doing, maybe your app's structure isn't very well suited to the Arduino framework. Maybe you need to write smaller code than what would be produced by Arduino, sometimes you just can't run Arduino at all...

Using the Arduino IDE or the Antipasto IDE can be limiting for serious development owing to their design being focused for computer newbies, abstracting away what is going on under the hood.

The '$' character introduces parameter expansion, command substitution, or arithmetic expansion.

Regular expressions are very powerful tools for matching, searching, and replacing text. Unfortunately, they are also very obtuse. It does not help that most explanations of regular expressions start from the specification, which is like learning to love Friends reruns by reading a VCR manual. This page provides some simple examples for reference.

Nice GDE

Creating headers and footers in Latex can be done by using the package "fancyhdr". This is a short introduction, showing the most important features of the package. If you know "fancyhdr" and are looking for something particular, refer to the fancyhdr-documentation.

This website is the home of the Revised Slackware Book Project (the project). The regulars on alt.os.linux.slackware (a newsgroup) have been discussing the revision of "The Book", otherwise known as "Slackware Linux Essentials - The Official Guide To Slackware Linux", created by David Cantrell, Logan Johnson & Chris Lumens.
