Some times we need to create Ramdisk for temporary use. Very easily you can make a ramdisk. it is lightning fast, because it is in RAM.

Open a Terminal

On occasion I have a need for a tiny, lightning fast Linux distribution to boot into in order to check various issues on a machine. Either that or I just don’t want to monkey around with someone else’ data. Either way, I will often grab for either a CD or flash drive containing my favorite “micro” distribution, Puppy Linux.

Previously, we examined the impact of journal size using a separate disk on metadata performance as measured by fdtree. In this follow-up we repeat the same test but use a ramdisk for the journal, thereby boosting the best performance. Or does it?

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.

BackTrack 5, a Linux distribution designed for pentesters and security professionals or those who want to mess with all the best security and penetration testing applications the free software community has to offer.

This latest article provides the steps you need to dual-boot it and Ubuntu 12.04 on a computer with a single hard drive.

The word cool takes an ever more significant meaning when you consider a Linux distribution running from a USB drive.

So I have a laptop that I've been upgrading since Hardy (currently on Karmic Alpha) that I would like to boot faster. It has probably accumulated a lot of crufty daemons along the way that probably aren't being pre-loaded into memory. I picked up this tidbit from the fast boot expert. Add profile to your kernel command-line (at the grub prompt, press Esc e and then edit the line).

This article describes Puppy Linux, a flexible, fast distribution that's always a favorite among DesktopLinux readers. Author Dave Dibble briefly reviews MiPup2, one of many ready-made Puppy "puplets," and updates us on Puppy's current state and planned new features.

"If you believe Jeff Jones, Microsoft's security strategy director, then Vista is much more secure than XP, Mac OS X, and Linux."
