Benchmarking Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3551 Comments
Tutorial quote: I recently purchased a Western Digital 250GB/8M/7200RPM drive and wondered which journaling file system I should use. I currently use ext2 on my other, smaller hard drives. Upon reboot or unclean shutdown, e2fsck takes a while on drives only 40 and 60 gigabytes. Therefore I knew using a journaling file system would be my best bet. The question is: which is the best? In order to determine this I used common operations that Linux users may perform on a regular basis instead of using benchmark tools such as Bonnie or Iozone. I wanted a "real life" benchmark analysis. A quick analogy: Just because the Ethernet-Over-Power-Lines may advertise 10mbps (1.25MB/s), in real world tests, peak speed is only 5mbps (625KB/s). This is why I chose to run my own tests versus using hard drive benchmarking tools.

Reset your Settings for any Program

Post date: November 11, 2007, 05:11 Category: Desktop Views: 3581 Comments
Tutorial quote: Ever messed with settings and majorly screwed something up? I have.

Yesterday I was trying to pull a stunt by trying to embed Konsole in my KDE desktop and when I restarted the X server I had no desktop icons and couldn’t even get back to my settings to change it back! I was thinking OMG, RRR (Repartition, Reformat, Reinstall) time.

But wait, what if I just clear out my settings? Kind of a crude way of doing it, but it worked.

Three Ways To Access Linux Partitions (ext2/ext3) From Windows On Dual-Boot Systems

Post date: January 20, 2008, 12:01 Category: Miscellaneous Views: 7641 Comments
Tutorial quote: If you have a dual-boot Windows/Linux system, you probably know this problem: you can access files from your Windows installation while you are in Linux, but not the other way round. This tutorial shows three ways how you can access your Linux partitions (with ext2 or ext3 filesystem) from within Windows: Explore2fs, DiskInternals Linux Reader, and the Ext2 Installable File System For Windows. While the first two provide read-only access, the Ext2 Installable File System For Windows can be used for read and write operations.

File Server Configuration in Debian Using Samba

Post date: May 1, 2007, 05:05 Category: System Views: 4377 Comments
Tutorial quote: Samba is a suite of Unix applications that speak the SMB (Server Message Block) protocol. Many operating systems,including Windows and OS/2, use SMB to perform client-server networking. By supporting this protocol, Samba allows Unix servers to get in on the action, communicating with the same networking protocol as Microsoft Windows

Tutorial quote: One common server bottleneck is DNS lookups. Many common server tasks such as from looking up hostnames to write Apache logfiles and processing incoming mail require the use of DNS queries. If you're running a high-traffic system it might be useful to cache previous lookups.

Using multiple network cards in XEN

Post date: December 10, 2006, 09:12 Category: Emulation Views: 8480 Comments
Tutorial quote: Xen is great. But installing more than one network card became a pain when I tried it the first time. There are some documents describing the principle but I was unable to find a real life example somewhere else. So this is a summary about how it works here now.
