"GlusterFS is a scale-out NAS file system developed by Gluster. It aggregates various storage servers over Ethernet or Infiniband RDMA interconnect into one large parallel network file system. GlusterFS is based on a stackable user space design without compromising performance. It has found a variety of applications including cloud computing, biomedical sciences and archival storage. GlusterFS is free software, licensed under GNU AGPL v3 license."

Sounds quite impressive.

It remains to be seen whether the recent acquisition of Gluster Inc. (by Red Hat) interferes with the open-source product's development/availability or not.

Running fsck.ext3 with the -c checks the filesystem for read errors and creates a (new) bad block list. However what if you want to revert this operation, because you want to access files that occupied these bad blocks? Here's the answer: fsck.ext3 -L /dev/null [device]

"Double Commander is a cross platform open source file manager with two panels side by side. It is inspired by Total Commander and features some new ideas."

Up to date this commander seems to be the best Total Commander clone for linux.

"Imagine you have made a world tour in August 2009 (summer time!) and you have used your digital photo camera to create pictures, videos and voice recordings.

In this guide I will not refer to these items by their specific characteristics (photo, video, audio), but simply regard all of them as "files." Secondly, we assume that the files are saved on a storage medium, which is very likely formatted as FAT (as specified in the DCIM standard for digital cameras).

You have created three files in America/Los Angeles (UTC-0700), three files in your hometown Europe/Vienna (UTC+0200) and three files in Asia/Bangkok (UTC+0700), and at the end of the summer, you return to your hometown Europe/Vienna.

This guide shows you how to correctly bring your files' timestamps from a local time zone-based file system (such as your external flash drive, formatted as FAT32) to a file system using coordinated universal time (UTC) (such as your internal hard disk, formatted as HFS+) using the Finder on MacOS X."

Actually this guide is relevant not only for Mac OS X users, but everybody involved with files that have dates from a number of timezones. The same steps should be followed by Windows (etc.) users as well.

The "original" program was KDirStat and clones for Windows (WinDirStat) and Mac OS X (Disk Inventory X) were made later on.

They are all disk usage utilities and show the sizes of files and folders in a special graphical way called "treemaps".

You can force a filesystem check of the automatically mounted partitions on the next boot by creating a file with the name forcefsck in the root directory. You could simply use:
as root. The file will be automatically removed after a successful fsck during the boot process.
