I've just found a nice article about enabling DNS-Cache for Konqueror at fedorawiki.de. It's very useful, because Konqueror doesn't provide this feature. If you take e.g. the german freemail provider http://gmx.net, Konqueror sends a huge amount of dns queries to load all the pictures and stuff. You really notice the performance gain if you cache these queries with a local DNS server, for example dnsmasq.

Here are the steps to install and configure dnsmasq:

Full package name: kde-misc/kicker-compiz

From the kde-apps.org project page:
"This is a modified pager applet for kicker to make it work with compiz. More generally, it is intended to work with window managers that use the concept of "large desktops" instead of "multiple virtual desktops" as kwin does exclusively."

I quite like the fork because it provides boarderless transparent snippets of your desks.

Hey, here is a new ebuild. I performed some updates (translations, etc.) on the original package. This is a testing version.

Note
You have to download both files (.ebuild and .patch file)! Put the patch into your files/ directory. Refer to the Gentoo wiki for more information: http://gentoo-wiki.com/HOWTO_Installing_3rd_Party_Ebuilds

Full package name: app-admin/blockhosts

Ok, this isn't really new; I decided to extract the ebuild from the HowTo.
So here is the blockhosts ebuild.

Some information about the package:
Blockhosts is a python script which records how many times a system service has been probed, using configurable pattern matching to recognize failed accesses (such as for "sshd" or "proftpd" or any service), and when a particular IP address exceeds a certain number of failed attempts that IP address is blocked by using one of the following techniques, e.g.:

What is BlockHosts?

Blockhosts is a python script which records how many times a system service has been probed, using configurable pattern matching to recognize failed accesses (such as for "sshd" or "proftpd" or any service), and when a particular IP address exceeds a certain number of failed attempts that IP address is blocked by using one of the following techniques, e.g.:

• using TCP_WRAPPERS (writes to /etc/hosts.allow)
• using "ip route" commands to setup null-routing for attackers
• using IPtables to setup packet filtering for attackers
