How to Convert .cue and .bin files into an .iso file

bchunk converts a CD image in a ".bin / .cue" format (sometimes ".raw / .cue") to a set of .iso and .cdr tracks. The bin/cue format is used by some non-Unix cd-writing software, but is not supported on most other cd-writing programs.

image.bin is the raw cd image file. image.cue is the track index file containing track types and offsets. basename is used for the beginning part of the created track files.

The produced .iso track contains an ISO file system, which can be mounted through a loop device on Linux systems, or written on a CD-R using cdrecord. The .cdr tracks are in the native CD audio format. They can be either written on a CD-R using cdrecord -audio, or converted to WAV (or any other sound format for that matter) using sox.

Installation on Ubuntu Intrepid: sudo apt-get install bchunk

To convert .cue and .bin files, navigate to the folder and run this command (replacing filenames with your own):
bchunk inputfilename.bin inputfilename.cue outputfilename.iso

After the file is converted into ISO you can mount it using: sudo mount -o loop outputfilename.iso /media/output
Navigate to /media/output and you should see all the content there. You can then copy it anywhere.
To unmount: sudo umount /media/output


Installation on OpenSuse: OpenSuse user can use "1-click" installer to install bchunk

How to use Aptitude on Ununtu

Aptitude is a terminal-based package manager that can be used instead of apt-get. Aptitude marks packages that are automatically installed and removes them when no packages depend on them. This makes it easy to remove applications completely. To use Aptitude, replace apt-get with aptitude in the command line. Example:

sudo aptitude install packagename
sudo aptitude remove packagename
sudo aptitude update
sudo aptitude upgrade

For an ncurses-based graphical user interface, type sudo aptitude

How to install a Ubuntu package from source code

Make sure you have all the necessary development tools (i.e. libraries, compilers, headers):

sudo apt-get install build-essential
sudo apt-get install linux-headers-`uname -r`

Note: "uname -r" lists the current kernel you are using

Extract the archive that contains the source files: tar xvf sourcefilesarchive.tar.gz

Build the package using the package's script (in this case the configure script), compile the package (make), and install the compiled package into your system (make install):

cd /path/to/extracted/sourcefiles
./configure
sudo make
sudo make install

If you get a "permission denied" error when trying to execute the binary, this means that the file is not marked as being executable. To fix this: sudo chmod +x filename

Spam Filtering using Procmail & SpamAssassin

When Procmail is used in conjunction with SpamAssassin. When used together, these two applications can quickly identify spam emails, and sort or destroy them.

SpamAssassin uses header analysis, text analysis, blacklists, a spam-tracking database, and self-learning Bayesian spam analysis to quickly and accurately identify and tag spam.

The easiest way for a local user to use SpamAssassin is to place the following line near the top of the ~/.procmailrc file:

INCLUDERC=/etc/mail/spamassassin/spamassassin-default.rc

The /etc/mail/spamassassin/spamassassin-default.rc contains a simple Procmail rule that activates SpamAssassin for all incoming email. If an email is determined to be spam, it is tagged in the header as such and the title is prepended with the following pattern:

*****SPAM*****

Since SpamAssassin is a Perl script, it may be necessary on busy servers to use the binary SpamAssassin daemon (spamd) and client application (spamc). To start the spamd daemon, type the following command as root: /sbin/service spamassassin start and make sure the spamassassin is set to autostart at booting time
        
To configure Procmail to use the SpamAssassin client application instead of the Perl script, place the following line near the top of the ~/.procmailrc file. For a system-wide configuration, place it in /etc/procmailrc:

INCLUDERC=/etc/mail/spamassassin/spamassassin-spamc.rc

How to verify that a package (rpm) has not been corrupted or tampered

If you wish to verify that a package has not been corrupted or tampered with, examine only the md5sum by typing the following command at a shell prompt (where is the file name of the RPM package):

rpm -K --nosignature

e.g) # rpm -K --nosignature amarok-1.4.10-26.1.i586.rpm
amarok-1.4.10-26.1.i586.rpm: sha1 md5 OK


The message : md5 OK is displayed. This brief message means that the file was not corrupted by the download. To see a more verbose message, replace -K with -Kvv in the command.

What is Btrfs?

Btrfs (B-tree FS or "Butter FS") is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone.

Linux has a wealth of filesystems to choose from, but we are facing a number of challenges with scaling to the large storage subsystems that are becoming common in today's data centers. Filesystems need to scale in their ability to address and manage large storage, and also in their ability to detect, repair and tolerate errors in the data stored on disk.

The main Btrfs features include:
  * Extent based file storage (2^64 max file size)
  * Space efficient packing of small files
  * Space efficient indexed directories
  * Dynamic inode allocation
  * Writable snapshots
  * Subvolumes (separate internal filesystem roots)
  * Object level mirroring and striping
  * Checksums on data and metadata (multiple algorithms available)
  * Compression
  * Integrated multiple device support, with several raid algorithms
  * Online filesystem check
  * Very fast offline filesystem check
  * Efficient incremental backup and FS mirroring
  * Online filesystem defragmentation

How to recover deleted pictures and Video files

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its 'Photo Recovery' name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media's filesystem has been severely damaged or re-formatted.

PhotoRec is free, this open source multi-platform application is distributed under GNU Public License. PhotoRec is a companion program to TestDisk, an app for recovering lost partitions on a wide variety of filesystems and making non-bootable disks bootable again.

For more safety, PhotoRec uses read-only access to handle the drive or memory support you are about to recover lost data from. Important: As soon as a pic or file is accidentally deleted, or you discover any missing, do NOT save any more pics or files to that memory device or hard disk drive; otherwise you may overwrite your lost data. This means that even using PhotoRec, you must not choose to write the recovered files to the same partition they were stored on.

PhotoRec searches for known file headers. If there is no data fragmentation, which is often the case, it can recover the whole file. Photorec recognises numerous file format including ZIP, Office, PDF, HTML, JPEG and various graphics file formats. The whole  list of file formats recovered by PhotoRec contains more than 180 file extensions (about 100 file famillies).

Installation:
OpenSuse 11.1 user can use "1-click" installer to install PhtoRec - here

After sucessfull installation go to terminall and fire command: PhtoRec to open the PhtoRec console, you need to be "root" to use PhtoRec

Below are the few screen shots on how to use and recover files using PhtoRec, it's an menu driven and see to figure out the options

How to Compress Javascript

First, you can try to make the javascript file smaller itself. There are lots of utilities to “crunch” your files by
removing whitespace and comments.

You can do this, but these tools can be finnicky and may make unwanted changes if your code isn’t formatted
properly. Here’s what you can do:

1. Run JSLint (online or downloadable version) to analyze your code and make sure it is well-formatted.

2. Use Rhino to compress your javascript. There are some online packers, but Rhino actually analyzes your source
code so it has a low chance of changing it as it compresses, and it is scriptable.

Install Rhino (it requires Java), then run it from the command-line:

java -jar custom_rhino.jar -c myfile.js > myfile.js.packed 2>&1
 
This compresses myfile.js and spits it out into myfile.js.packed. Rhino will remove spaces, comments and shorten
variable names where appropriate. The “2>&1″ part means “redirect standard error to the same location as the
output”, so you’ll see any error messages inside the packed file itself (cool, eh? Learn more here.).

Analyzing boot performance of OpenSuse 11.1 with bootchart

Often the boot process of a machine is not as fast as one would like. It is commonly suggested that you reduce the number of started services so that your machine boots up faster. However, one thing we must know before trying to optimize our boot process, is where it is slow. To do that, we will use a tool called bootchart.

Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization data and process information are collected during the boot process, and can later be displayed in a PNG, SVG, or EPS encoded chart. Analyzing the chart will help in finding opportunities for optimization.

The first thing we must do is, obviously, install the package, open yast -- software managment and search for "bootchart" and click on "Accept" to install bootchart


Bootchart provides a shell script to be run by the kernel in the init phase. The script will run in background and collect process information, CPU statistics and disk usage statistics from the /proc file system. The performance data are stored in memory and are written to disk once the boot process completes.

The boot log file is later processed using a Java application (or the web form) which builds the process tree and renders a performance chart in different formats.

Configuration:
Bootchartd mounts a tmpfs below /tmp, so make sure you don't clear this at boot time, otherwise you will have invalid data.

Especially check the setting of: CLEAR_TMP_DIRS_AT_BOOTUP in sysconfig/cron

Reboot your system and after reboot you will find two files (bootchart.tgz and bootchart.png) under /var/log directory and this png file will give you detail view of the time that a particular process has taken while booting so that you can look into it and can optimize it for faster booting.

301 Redirects using apache

301 redirect is the safest search engine redirect. This is also the friendliest method for web page redirection. Most web hosting company and web master out there will definitely recommend this method of web page redirection. The code “301 is interpreted as “moved permanently”.

For websites hosted in either dedicated server or a shared web hosting server, you use 301 redirects in redirecting a single html page or an entire website.

Here’s and example of redirecting a single page/html page:
Redirect 301 /oldpage.html http://www.example.com/newpage.html
For a whole website, you can use 301 redirect in this manner:
Redirect 301 / http://www.example.com/
There are other use of the 301 redirect on a web sites. Here are other use of it:

Changed file extension
Redirect web site with ‘www’ to not having one.
vice versa of the previous example.
Redirect example.com/index.php to example.com/

So next time you moved your web site content from one web hosting server provider to another or moving your site to a new domain name, you can definitely use the 301 redirect.

This is simple configuration you can make it into your Apache configuration file.
