If your browsers work OK, you do not need to disable IPv6. Also, there is nothing wrong with either Ubuntu (Karmic) or IPv6, so if you are experiencing any issues, they are because of your ISP / router / modem.

Ziproxy is forwarding, non-caching, compressing HTTP proxy server coming to the rescue of Linux (bot 32 and 64 bit) users with slow internet connections. Basically it squeezes images by converting them to lower quality JPEGs or JPEG 2000 and compresses (gzip) HTML and other text-like data.

Trickle is a Linux application which allows you to limit the network bandwidth of individual applications such as a torrent client, web browsers or any other program.

BaShare (Basic Share) is a very simply and user-friendly file sharing tool over the Internet and private LAN too.

pyshaper lets you set bandwidth minimum and maximum limits on several criteria:
* remote host/port, and local host/port (most shaper apps have this)

tmpfs is a virtual, RAM-backed filesystem. It’s lightning-fast, but since it’s RAM-backed, any file written to tmpfs uses precious memory while it’s there, and the entire contents of the virtual partition are lost on shutdown or crash. The good news is that these detriments can be minimized, making tmpfs a viable choice for your profile directory.

Firefox 3.1 Beta 1 is now available for download. This milestone is focused on testing the core functionality provided by many new features and changes to the platform scheduled for Firefox 3.1. Ongoing planning for Firefox 3.1 can be followed at the Firefox 3.1 Planning Center, as well as in mozilla.dev.planning and on irc.mozilla.org in #shiretoko.

Not only Firefox became in a relatively short amount of time the most popular web browser on Linux, but it also turned out to be the most powerful competitor to Internet Explorer on Windows, proving itself faster, more stable, more flexible and secure. Some would say Firefox is one of the most important proofs that open-source can and is actually better than closed, proprietary software.

Mozilla Corp. today announced the winners of its third “Extend Firefox” contest, an annual competition that recognizes the year’s best Firefox add-ons.

We released 9.52 today, which addresses several security and stability issues. This release is a recommended upgrade for all those running the latest stable releases.

OS X is without a doubt the easiest OS for configuring Bluetooth devices. Adding phones, keyboards and headsets is (more or less) as easy as it could be. Windows is way behind. You can add your phone, but where OS X automatically sets up the phone as a modem connection, you will have to download some PC Suite crap or hack your way onto the phone. Ubuntu is somewhere between Windows and OS X, but (sad to say) closer to Windows.
