In modern computer systems, the biggest bottleneck of information tends to be in communicating with the hard disks. High seek times and relatively slow transmission rates when compared to RAM speeds can add up quickly. This was a necessary evil back when RAM space and costs were at a premium, but now it is not uncommon to see 4GB of RAM on laptops, and even 12GB on desktops. For  users whose primary computer use is browsing the internet (either for work, writing articles, or lolcats) and have some extra RAM, moving the browser cache to the RAM from the hard disk is a definite option for increasing speed.

In Linux systems (specifically Fedora and Ubuntu systems), this can be achieved for Chrome and Firefox by creating a larger ramdisk, mounting the ramdisk after boot, and then setting the browser of choice to use that ramdisk as a cache. The necessary commands to do this are readily available on the internet, which makes life easy. Using ramdisks for performance boosts are not exclusive to browsers, and can be used for other software such as Nagios for example.

We have previously covered a tool called Espérance DV for moving cache to RAM in Mac OSX, and for any Windows users feeling left out, there are ways of making Firefox bend to your will. Obviously you will see an increase in RAM use (duh), but this shouldn’t be a problem unless you are running out of free RAM on your system. Remember, free RAM is wasted RAM.

The devs over at the Fedora Project are hard at work on the development version: Rawhide. They’ve just setup automated nightly builds of the liveCD which can easily be downloaded and tested on a CD, DVD, USB drive, virtual machine, or separate partition.

Rawhide will be released as Fedora 12 upon completion.  With this version you have a choice of Gnome 2.28 or KDE 4.3 for your desktop.  There is also improved power management, expanded support for mobile broadband, easy bug reporting, and many more new or improved features. So roll up your sleeves, download last night’s build, and help test some open source software.

After a week of wondering, Red Hat has confirmed that someone broke in and compromised their security. Although It doesn’t appear the attacker was able to retrieve the passphrase used to sign Fedora packages, the team is switching to new keys. In a separate intrusion the attacker tampered with and signed OpenSSH packages for RHEL. While it’s good to get the full story, no one is happy how long it took Red Hat to release these details.
