Here is a good tip for the novices and rookies to use.
Change rm to alias=’rm -i’.

This way, every time you delete a file, the system will ask if you’re sure.

The second tip is to do backups. You can use a utility like rsync to copy the important directories and files to another system or partition. You can set a crontab to do this daily or even hourly.

1. Recover – automates some steps as described in the Ext2fs-Undeletion-howto in order to recover a lost file. This utility will greatly increase your file recover rate. People who do not know how to undelete a file are encouraged to use this utility.

2. athena-delete – was written at Project Athena in response to the problem which many novice UNIX users have with accidentally deleting files they didn’t want to delete.
3. unrm – a small shell utility which can, under some circumstances, recover almost 99% of your erased data (similar to DOS’s undelete). Read carefully the FAQ file and preferably the Linux Ext2fs Undeletion Mini-HOWTO before using it.

Usage:  unrm [-b (no block padding)] [-e (every block)] [-f fstype] [-vW] device [block.. ]

4. gET iT i sAY – a file recovery tool for Ext2/Ext3 filesystems. Once installed, current files and newly created files from /root and /home are recovered. It allows users to recover all deleted files, recover files owned by a specific user, dump data from old file locations, and recover files of a specific type, such as text or MP3. A forensic analyzer is also provided to assist users during recovery.
5. e2undel – an interactive console tool that recovers the data of deleted files on an ext2 file system under Linux. A library that allows you to recover deleted files by name is included. e2undel does not manipulate any internal ext2 structures, and it does not require any additional tools. It should be useable without knowledge of the ext2 internal.

Usage: e2undel –d device –s path [-a] [-t]
-d file system where to look for deleted files
-s directory where to save undeleted files
-a work on all files
-t try to determine type of deleted files w/o names
-l just give a list of valid file in undel log file
Device should not be mounted, and path should not reside within device

6. anyfs-tools – allows you to recover and convert filesystems while using minimal extra disk space. Unlike other recovery tools, anyfs-tools doesn’t copy all the files found on other disks (or partitions), but only saves information about the location of the file blocks to an external inode table. After recovery, a user may mount the damaged filesystem with anyfs and the external inode table and then interact with all recovered files with any program.
7. rfs – a shell script for creating and updating a local spare system disk. The main goal is to recover a working system after a crash quickly. In this case, “quickly” means the time it takes to reboot the machine. rfs stands for “replication of filesystems”. Like rsyncbackup, rfs is built on top of rsync.
8. e2retrieve - an Ext2 data recovery tool that works on truncated or partial filesystems. It is very useful to retrieve data when a disk from an LVM crashes. It does not repair the filesystem but extracts and copies most of the data it can from raw Ext2 data given to it.
9. findfile – a collection of tools for recovering files from filesystems with corrupted directories, allocation tables, etc. This can be useful when the partition table (or more) of a hard disk is corrupted, or when you have a memory card of a digital camera which is corrupted.
10. TestDisk – a tool to check and undelete partitions. It works with the following partitions: FAT12, FAT16, FAT32, Linux, Linux swap (version 1 and 2), NTFS (Windows NT/W2K/2003), BeFS (BeOS), UFS (BSD), JFS, XFS, and Netware.

To resize your Vista Partition click on Start – Control Panel

Double Click the Administrative Tools Icon.

In the administrative tools window you will see Computer Management. Double click it.

Now that you have computer management open, look down the list on the left. Click on Disk Management. Now look at the top middle part of the window. Find the disk you want to resize and single click on it. Once you have done this a list of volumes on that drive will appear below the top window.
Right click on the volume you want to resize and you will be given the option to shrink or expand it. If an option is grayed out it means you either cannot shrink it any smaller, or cannot expand it any larger.

We will be shrinking my drive.

When it is shrinking there is no progress bar or window so just hold steady until the process is finished.  It took about 30 seconds for my drive to be shrunk.

To describe this product as a simple and fast clustered J2EE cache does not do it justice. From the Tangosol’s website Coherence:

    “enables in-memory data management for clustered J2EE applications and application servers. Coherence makes sharing and managing data in a cluster as simple as on a single server. It accomplishes this by coordinating updates to the data using cluster-wide concurrency control, replicating and distributing data modifications across the cluster using the highest performing clustered protocol available, and delivering notifications of data modifications to any servers that request them. Developers can easily take advantage of Coherence features using the standard Java collections API to access and modify data, and use the standard JavaBean event model to receive data change notifications.”

This description outlines the most significant features of this software package, and the proof of in its quality lies it’s continued popularity, as well as a list of customers that reads as who’s who of the Big International Business. Recently, Network World ranked Coherence as the number two best network architecture/software product surpassed only by VMware’s offering. This alone speaks firmly for a high credibility of this package.

By far, the best feature provided by Coherence is its seamless integration into existing environment, and no headache scalability features that enable administrators to add and remove servers to and from their clusters. Coherence dynamically adjusts itself by discovering new servers, providing fail-over services and reorganizing itself to manage the data grid cluster.

Also, partnership with industry leaders like HP, IBM, BEA, and others ensures that this Cache is compatible with a wide range of hardware and software that runs the infrastructures of businesses all over the world.

Tangosol, Inc. is the industry’s leading provider of reliable data grid solutions enabling enterprises to predictably scale mission-critical applications.
