Arcane Linux Commands: dc

Post date: December 31, 2007, 01:12 Category: Miscellaneous Views: 3428 Comments
Tutorial quote: If anybody within earshot of you is struggling to learn sed and ever remarks "This is like learning Klingon! Could they make it any more cryptic?", you can always point them to dc.

dc is the command-line Unix "Reverse-Polish Notation"(RPN) calculator. The name stands for "desktop calculator". OK, so what is a Polish calculator and why would you want to reverse one? The math that you do in school uses infix notation, with the operator between the numbers (3 + 5). Prefix notation puts the operator first (+ 3 5) and is what the Lisp language uses. The prefix notation is known as "Polish notation" after the nationality of Jan Łukasiewicz who invented it. Postfix notation, then, has the operator at the rear (3 5 +), and so is also the reverse of Polish notation.

What's the difference? In computer programming, you have to specify what order you want a multi-part calculation to be in. Everybody is familiar with the old problem of A*B-C. For A=5, B=3, C=2, multiplying first and subtracting second gives you 13, while subtracting first and multiplying second gives you 5. To specify which operations you want performed first, you have to either memorize the complex orders of operations (which change from one language to the next) or use a lot of parenthesis ((A*B)-C) or (A*(B-C)). Hey, that's what everybody complains about in all those languages that use parenthesis!

Linux Directory Structure

Post date: December 26, 2007, 15:12 Category: Miscellaneous Views: 4316 Comments
Tutorial quote: The directory structure of Linux/other Unix-like systems is very intimidating for the new user, especially if he/she is migrating from Windows. In Windows, almost all programs install their files (all files) in the directory named: `Program Files.’ Such is not the case in Linux. The directory system categorises all installed files. All configuration files are in /etc, all binary files are in /bin or /usr/bin or /usr/local/bin. Here is the entire directory structure along with what they contain.

Creating Encrypted FTP Backups With duplicity And ftplicity On Debian Etch

Post date: December 18, 2007, 12:12 Category: Miscellaneous Views: 3288 Comments
Tutorial quote: When you rent a dedicated server nowadays, almost all providers give you FTP backup space for your server on one of the provider's backup systems. This tutorial shows how you can use duplicity and ftplicity to create encrypted (so that nobody with access to the backup server can read sensitive data in your backups) backups on the provider's remote backup server over FTP. ftplicity is a duplicity wrapper script (provided by the German computer magazine c't) that allows us to use duplicity without interaction (i.e., you do not have to type in any passwords).

Comprehensive Linux System Services List: Explanation and Recommendation

Post date: December 17, 2007, 06:12 Category: Miscellaneous Views: 3525 Comments
Tutorial quote: Linux services are basically programs that start at boot time to provide certain features and services (Apache, the web server for example). After installation, every Linux distribution provides a list of enabled services. However, you might not need some of these services or you might need others that are not enabled by default. Having only the services you need running will make your system faster, more stable and secure. So the first thing you need to do after installing a Linux distribution is to manually edit the list of enabled services. Unfortunately, some services don’t provide a description, others provide a description that’s not understandable so you might end-up disabling a vital system service just because you didn’t know what it did and you thought you didn’t need it.
