Ubuntu is an awesome Linux distribution. I encrypted my mobile hard drive by dm-crypt. Now when I plug it onto my USB port, it will automatically prompt me to input the passphrase. After that, I can visit this hard drive through Nautilus, the File Manager of GNOME desktop environment.

LAMP is a killer application on Linux. It is a also a killer application of open source solutions.
1. Before you start, please install some required packages

         sudo apt-get install build-essential flex libncurses5-dev libxml2-dev libxml2-util 

2. Let's compile Apache.

dm-crypt, an encryption on a mapping device was introduced into stable Linux kernel since kernel version 2.6.4. Encryption on a mapping device means data are firstly written into a mapping device, which is virtual and mapped to a real physical devices. In this manner, you can encrypt the entire partition, including the file system journals. dm-crypt also has a good extension, LUKS, Linux Unified Key Setup.

In this article, I will introduce two options. The first one doesn't use LUKS and is suitable for internal hard drives. The second one uses LUKS and is suitable for removable storage, such as USB memory stick.

The environment is Ubuntu 9.04. But I think it should also work for other Linux distributions.

All what we later do are performed on a Linux shell. Although Cadence provides the GUI tools to download archives and load software, I prefer the command line version. Please make sure that you have the write permission on all directories to be operated.

I am planning to use two packages now, one is SPB, the Silicon Package Board, and ADW, Allegro Design Workbench.

Cadence distributes their software as three categories, Base, Update and Hotfix. You should install Base first, and then Update, and then Hotfix.

Many people wanna find the solution to create PDF docs on Linux as Adobe Acrobat in Windows. Actually it is very easy. You just need two things, CUPS and CUPS-PDF. They can convert anything to PDF on Linux. And they are all free software.

If you have set the privilege to some files and directories to be accessible on Linux, but Apache 2 said

403 Forbidden
Forbidden
You don't have permission to access / on this server.

That is maybe 'cause you haven't set the privilege on Apache 2 configuration file.
