Gentoo

Build your own Gentoo rescue LiveCD and USBStick

Post date: June 20, 2005, 04:06 Category: Miscellaneous Views: 4943 Comments
Tutorial quote: I've written this how-to after trying to find a boot medium for my home gateway machine which could be used for system rescues and even installing Gentoo. Why not use the standard Gentoo Live CD you ask? Well my gateway machine is one of those small, silent and cool running mini-itx machines (http://www.mini-itx.com) and has no CDROM or floppy drive. I needed some way of getting Gentoo on there and some way of easily rescuing it when the need arises. The good news is that these VIA mini-tix machines are USB bootable and I much preferred the idea of having a little USB drive/stick that I could push into any USB bootable machine and boot into Linux rather than having to set up a PXE networked boot environment (which is also supported).

Introduction to Free Pascal 2.0

Post date: May 16, 2005, 23:05 Category: Programming Views: 2945 Comments
Tutorial quote: After five years of development, Free Pascal 2.0 is ready. With the new compiler, its authors believe they are ready to become a larger open source development platform. In the MS-DOS world, Pascal was one of the major programming languages and is by means of Borland Delphi an important programming language in the Windows world. In the open source world, Free Pascal is the leading Pascal compiler and while open source is a bit biased using the C language, the Pascal language has a lot to offer to open source programmers.

Arcane Linux Commands: dc

Post date: December 31, 2007, 01:12 Category: Miscellaneous Views: 3476 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!
