How to keep a detailed audit trail
Intrusions can take place from both authorized and unauthorized users. My personal experience shows that unhappy user can damage the system, especially if they have a shell access. Some users are little smart and removes history file (such as ~/.bash_history) but you can monitor all user executed commands.

This article shows how to log user activity using process accounting. It allows you to view every command executed by a user including CPU and memory time. You can easily find out which commands used to take down your system with these utilities.

There is only one substantial problem with GNU -- they discourage use of the standard text editor in favor of a non-standard lisp interpreter. Fortunately, development of the standard text editor has not ceased, and I am glad to report that ed v. 0.3 was released.

MySQL Internationalisation Gotcha
timeless over at Digg warns us about a problem when converting a database in MySQL to UTF8.
"Recently at Digg we started doing internationalisation efforts. Our database was storing data in latin1 character set although PHP was using the UTF8 character set. That limited our language support, so we decided to convert the DB to UTF8."

Pointers and memory leaks in C
In this article you'll learn about the types of pointer operations that can cause memory corruption and you'll also examine some scenarios that show what to consider while working with dynamic memory allocation. Pointers and memory leaks might seem to be deterrents to some programmers but, once you understand the fundamentals of pointers and associated memory operations, they will be the most powerful tool you posses in C.

Slash'EM on Linux

When I tell my World of Warcraft/EverQuest-playing friends that I play Slash'EM, they usually raise their eyebrows and give me a slightly condescending smile before going on to explain how they prefer 3D graphics, interaction, etc. The fact is that comparing WoW/EQ to Slash'EM is like comparing movies to books. Did you read the Harry Potter books? Did you then go and see the movies? Slightly disappointed? Not quite what you expected? Then you'll have an inkling of what I'm on about.

It's a bit sad that Slash'EM is easier to install on Windows than it is to install onto many Linux systems. So, hopefully this article will address that issue.

Please see the full article on Basically Tech: Slash'EM on Linux: configure, install, setup and play.
