#image_magic:)
ImageMagick is a free and open source software package for modifying and creating images. Unlike graphics packages such as The GIMP that provide tools for manual creation and manipulation of images, ImageMagick is meant to be used by programs to generate and adjust images automatically. Interfaces are available for many programming languages, including Ada, C, C++, Java, Lisp, Pascal, Perl, PHP, Python, Ruby, and Tcl/TK. It can also be used from the command line.
MuseScore Version 1.0

MuseScore is an easy to use graphical editor to typeset music scores.
You can use the mouse or keyboard shortcuts to add and edit staffs and notes. Several templates are available.
These screenshots give you an idea of the beautiful typesetting.
You can also play your compositions, either by outputting them as MIDI files, or by enabling sound during editing. The latter option requires the installation of a sound font.
You can download the latest version from the project web site.
StepMania 1.2.5
With the rhythm video game StepMania you can choose from a large collection of songs and play a kind of video game where you follow the beat of the music and the motion of arrows in the video to tap keys on the keyboard or on game pads at the right moment. The more accurately you synchronize your moves with the music the more you will get rewarded.
Hidden Tips to enhance browsing with Mozilla Firefox
As Firefox has already created history being the most used web around as well as the most download i.e. 8.3 millions copies in a single day. Now today you will learn apart from being the most popular of the world it has lot more to offer, only thing you need to know some cool tips which will let you handle you favorite browser well easily. So to help out the millions of users find useful information in one place, I have created some list of tips and tricks for Firefox written by talented bloggers from around the blogosphere.
Hidden Tips to enhance browsing with Mozilla Firefox
1. Ever wish to have smaller icons to have more space, yes. you can do that via View – Toolbars – Customize and check the “Use small icons” box.
2. Creating a Keyword for a Search: If you very often do a particular type of search then do you instead of typing the same keyword every time in the Search Input box you can just “Add a Keyword for this search”, give the keyword a name and an easy-to-type and easy-to-remember shortcut name (let’s say “actor”) and save it. Now, when you want to do an actor search, go to Firefox’s address bar, type “actor” and the name of the actor and press return. Instant search! You can do this with any search box.
3. Have you tried the keypad shortcut to get your browsing faster, using shortcuts are one of the fasted way to reach to desired menu than using a mouse. But the problem not everyone is familier with the keyborad shortcuts used in Mozilla Firefox, here goes the list
5. If your habbit to use several tabs at a time than instead of using mouse every time why not just use the tab-switching; here are the shortcuts…
8. about:config. The true power user’s tool, about.config isn’t something to mess with if you don’t know what a setting does. You can get to the main configuration screen by putting about:config in the browser’s address bar. See about:config tips .
9. Adding bookmarks are also one of the easiest way to get to your favorite pages or websites but do you know you can Go to your bookmarks much faster by giving them keywords. Right-click the bookmark and then select Properties. Put a short keyword in the keyword field, save it, and now you can type that keyword in the address bar and it will go to that bookmark.
10. Having a broadband connection then why not just tweak out Firefox for better page loadsThis allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it’s optimized for dialup connections). Here’s how:
12. Reduce RAM when minimized: This setting will move Firefox to your hard drive when you minimize it, taking up much less memory. And there is no noticeable difference in speed when you restore Firefox, so it’s definitely worth a go. Again, go to about:config, right-click anywhere and select New-> Boolean. Name it “config.trim_on_minimize” and set it to TRUE. You have to restart Firefox for these settings to take effect.
13. Do you accidentally click on the close button of Firefox’s tabs? You can move them or remove them, again through about:config. Edit the preference for “browser.tabs.closeButtons”. Here are the meanings of each value:

- Ctrl+- (decrease text size)
- Ctrl-W (close tab)
- F5 (reload)

5. If your habbit to use several tabs at a time than instead of using mouse every time why not just use the tab-switching; here are the shortcuts…
- Ctrl+Tab (rotate forward among tabs)
- Ctrl+Shft+Tab (rotate to the previous tab)
- Ctrl+1-9 (choose a number to jump to a specific tab)
6. Mouse shortcuts: Sometimes you’re already using your mouse and it’s easier to use a mouse shortcut than to go back to the keyboard. Master these cool ones:

- Shift-scroll up (next page)
- Ctrl-scroll up (decrease text size)
- Ctrl-scroll down (increase text size)
- Middle click on a tab (closes tab)

10. Having a broadband connection then why not just tweak out Firefox for better page loadsThis allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it’s optimized for dialup connections). Here’s how:
- Type “. onfig” into the address bar and hit return. Type “network.http” in the filter field, and change the following settings (double-click on them to change them):
- Set “network.http.pipelining” to “true”
- Set “network.http.proxy.pipelining” to “true”
- Set “network.http.pipelining.maxrequests” to a number like 30. This will allow it to make 30 requests at once.
- Also, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.
12. Reduce RAM when minimized: This setting will move Firefox to your hard drive when you minimize it, taking up much less memory. And there is no noticeable difference in speed when you restore Firefox, so it’s definitely worth a go. Again, go to about:config, right-click anywhere and select New-> Boolean.

13. Do you accidentally click on the close button of Firefox’s tabs? You can move them or remove them, again through about:config. Edit the preference for “browser.tabs.closeButtons”. Here are the meanings of each value:
- 0: Display a close button on the active tab only
- 1:(Default) Display close buttons on all tabs
- 2:Don’t display any close buttons
- 3:Display a single close button at the end of the tab bar (Firefox 1.x behavior)
