Everybody’s favorite open-source browser, Firefox, is great right out of the box. And by adding some of the awesome extensions available out there, the browser just gets better and better.
But look under the hood, and there are a bunch of hidden (and some not-so-secret) tips and tricks available that will crank Firefox up and pimp your browser. Make it faster, cooler, more efficient. Get to be a Jedi master with the following cool Firefox tricks.
Infintytricks.blogspot.com
1) More screen space. Make your icons small. Go to View - Toolbars - Customize and check the “Use small icons” box.
2) Smart keywords. If there’s a search you use a lot (let’s say IMDB.com’s people search), this is an awesome tool that not many people use. Right-click on the search box, select “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) Keyboard shortcuts. This is where you become a real Jedi. It just takes a little while to learn these, but once you do, your browsing will be super fast. Here are some of the most common (and my personal favs):
* Spacebar (page down)
* Shift-Spacebar (page up)
* Ctrl+F (find)
* Alt-N (find next)
* Ctrl+D (bookmark page)
* Ctrl+T (new tab)
* Ctrl+K (go to search box)
* Ctrl+L (go to address bar)
* Ctrl+= (increase text size)
* Ctrl+- (decrease text size)
* Ctrl-W (close tab)
* F5 (reload)
* Alt-Home (go to home page)
4) Auto-complete. This is another keyboard shortcut, but it’s not commonly known and very useful. Go to the address bar (Control-L) and type the name of the site without the “www” or the “.com”. Let’s say “google”. Then press Control-Enter, and it will automatically fill in the “www” and the “.com” and take you there - like magic! For .net addresses, press Shift-Enter, and for .org addresses, press Control-Shift-Enter.
5) Tab navigation. Instead of using the mouse to select different tabs that you have open, use the keyboard. 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:
* Middle click on link (opens in new tab)
* Shift-scroll down (previous page)
* Shift-scroll up (next page)
* Ctrl-scroll up (decrease text size)
* Ctrl-scroll down (increase text size)
* Middle click on a tab (closes tab)
7) Delete items from address bar history. Firefox’s ability to automatically show previous URLs you’ve visited, as you type, in the address bar’s drop-down history menu is very cool. But sometimes you just don’t want those URLs to show up (I won’t ask why). Go to the address bar (Ctrl-L), start typing an address, and the drop-down menu will appear with the URLs of pages you’ve visited with those letters in them. Use the down-arrow to go down to an address you want to delete, and press the Delete key to make it disappear.
8) User chrome. If you really want to trick out your Firefox, you’ll want to create a UserChrome.css file and customize your browser. It’s a bit complicated to get into here, but check out this tutorial.
9) Create a user.js file. Another way to customize Firefox, creating a user.js file can really speed up your browsing. You’ll need to create a text file named user.js in your profile folder (see this to find out where the profile folder is) and see this example user.js file that you can modify. Created by techlifeweb.com, this example explains some of the things you can do in its comments.
10) 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 Mozillazine’s about:config tips and screenshots.
11) Add a keyword for a bookmark. 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.
12) Speed up Firefox. If you have a broadband connection (and most of us do), you can use pipelining to speed up your page loads. This 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 “about:config” 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.
13) Limit RAM usage. If Firefox takes up too much memory on your computer, you can limit the amount of RAM it is allowed to us. Again, go to about:config, filter “browser.cache” and select “browser.cache.disk.capacity”. It’s set to 50000, but you can lower it, depending on how much memory you have. Try 15000 if you have between 512MB and 1GB ram.
14) Reduce RAM usage further for when Firefox is 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.
15) Move or remove the close tab button. 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)

15 Coolest Firefox Tricks Ever
DBMS Description
A DBMS is a complex set of software programs that controls the organization, storage, management, and retrieval of data in a database. A DBMS includes:
1. A modeling language to define the schema of each database hosted in the DBMS, according to the DBMS data model.
* The four most common types of organizations are the hierarchical, network, relational and object models. Inverted lists and other methods are also used. A given database management system may provide one or more of the four models. The optimal structure depends on the natural organization of the application's data, and on the application's requirements (which include transaction rate (speed), reliability, maintainability, scalability, and cost).
* The dominant model in use today is the ad hoc one embedded in SQL, despite the objections of purists who believe this model is a corruption of the relational model, since it violates several of its fundamental principles for the sake of practicality and performance. Many DBMSs also support the Open Database Connectivity API that supports a standard way for programmers to access the DBMS.
2. Data structures (fields, records, files and objects) optimized to deal with very large amounts of data stored on a permanent data storage device (which implies relatively slow access compared to volatile main memory).
3. A database query language and report writer to allow users to interactively interrogate the database, analyze its data and update it according to the users privileges on data.
* It also controls the security of the database.
* Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called subschemas. For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data.
* If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases. However, it may not leave an audit trail of actions or provide the kinds of controls necessary in a multi-user organization. These controls are only available when a set of application programs are customized for each data entry and updating function.
4. A transaction mechanism, that ideally would guarantee the ACID properties, in order to ensure data integrity, despite concurrent user accesses (concurrency control), and faults (fault tolerance).
* It also maintains the integrity of the data in the database.
* The DBMS can maintain the integrity of the database by not allowing more than one user to update the same record at the same time. The DBMS can help prevent duplicate records via unique index constraints; for example, no two customers with the same customer numbers (key fields) can be entered into the database. See ACID properties for more information (Redundancy avoidance).
The DBMS accepts requests for data from the application program and instructs the operating system to transfer the appropriate data.
When a DBMS is used, information systems can be changed much more easily as the organization's information requirements change. New categories of data can be added to the database without disruption to the existing system.
Organizations may use one kind of DBMS for daily transaction processing and then move the detail onto another computer that uses another DBMS better suited for random inquiries and analysis. Overall systems design decisions are performed by data administrators and systems analysts. Detailed database design is performed by database administrators.
Database servers are specially designed computers that hold the actual databases and run only the DBMS and related software. Database servers are usually multiprocessor computers, with RAID disk arrays used for stable storage. Connected to one or more servers via a high-speed channel, hardware database accelerators are also used in large volume transaction processing environments.
DBMSs are found at the heart of most database applications. Sometimes DBMSs are built around a private multitasking kernel with built-in networking support although nowadays these functions are left to the operating system.
Logical view and physical view
A database management system provides the ability for many different users to share data and process resources. But as there can be many different users, there are many different database needs. The question now is: How can a single, unified database meet the differing requirement of so many users?
A DBMS minimizes these problems by providing two views of the database data: a physical view and a logical view. The physical view deals with the actual, physical arrangement and location of data in the direct access storage devices(DASDs). Database specialists use the physical view to make efficient use of storage and processing resources. Users, however, may wish to see data differently from how they are stored, and they do not want to know all the technical details of physical storage. After all, a business user is primarily interested in using the information, not in how it is stored. The logical view/user’s view, of a database program represents data in a format that is meaningful to a user and to the software programs that process those data. That is, the logical view tells the user, in user terms, what is in the database. One strength of a DBMS is that while there is only one physical view of the data, there can be an endless number of different logical views. This feature allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. Thus the logical view refers to the way user views data, and the physical view to the way the data are physically stored and processed.

HOW TO STOP SPAM VIA WINDOWS MESSENGER SERVICE
Below you'll find many ways (sorted in the most successful ratio first) to stop the Windows Messenger service, depending on your system environment, some may require more than one process. This service is available only on NT, 2K, XP & Server 2003. Administrator Login is REQUIRED
About The Messenger Service
* Messenger is a Windows Service that runs in the background
* Messenger is not the same as MSN Messenger or any other Instant Messaging Program
* Messenger does not facilitate two-way chatting
* Many Windows Programs, Firewalls, UPS and Antiviruses require the Messenger Service
* Antivirus and UPS software, among others, may not work if Messenger is disabled
* The Messenger Service is usually turned on by default in most Windows NT, 2K and XP systems
1. Manually
1. Example 1
1. Click Start, Run and enter the following command:
RunDll32 advpack.dll,LaunchINFSection %windir%\inf\msmsgs.inf,BLC.Remove
NOTE: This will prevent a long delay when opening Outlook Express if you have the Contacts pane enabled
2. To prevent this, click Start, Run and enter {REGEDIT} Go to:
HKEY_LOCAL_MACHINE\Software\Mcft\Outlook Express
3. Right click in the right pane and select New, Dword value
4. Give it the name Hide Messenger Double click this new entry and set the value to 2
5. End result should look EXACTLY like this:
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Mcft\Outlook Express]
Value Name: Hide Messenger
Data Type: REG_DWORD (DWORD Value)
Value Data: (2 = remove messenger)
2. Example 2
1. Copy and paste the following to Run Command Bar in the Start Menu:
RunDll32.exe advpack.dll,LaunchINFSection
%windir%\inf\msmsgs.inf,BLC.Remove
3. Example 3
1. If Example 5 didn't work, then try this - Many users miss or don't know of it
2. Click on Start then go to RUN and type:
C:\WINDOWS\inf\sysoc.inf
3. Change:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7
4. To:
msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,7
5. Then use Add/Remove Windows Components to remove Messenger
NOTE: You can also prevent access to Windows Messenger using Group Policy or the Set Program Access and Defaults utility added by default in Windows XP SP1 and Windows 2000 SP3
4. Example 4
1. Open Windows Messenger
2. From the menu, select "Tools" then "Options" then "Preferences" tab
3. Uncheck "Run this program when Windows starts"
4. Open Outlook Express
5. From the menu, select "Tools" then "Options" then "General" tab
6. Uncheck the option to "Automatically log on", if it's there
7. Also in Outlook Express, select "View" then "Layout"
8. Uncheck the option to "display Contacts" - The program will open a connection and display a list of all Contacts on line if you do not
9. In "Startup Folder" make sure there is no entry there for Messenger
10. Open Norton Anti-Virus if you have it installed
11. Click "Options" then "Instant Messenger"
12. Unckeck "Windows Messenger (recommended"
NOTE: This list ought to work in disassociate MSN from Outlook Express, so that it'll only start up if you really want it to
5. Example 5
1. 2000
* Click Start-> Settings-> Control Panel-> Administrative Tools->Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK
2. XP Home
* Click Start->Settings ->Control Panel
* Click Performance and Maintenance
* Click Administrative Tools
* Double click Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties
* Click the STOP button
* Select Disable in the Startup Type scroll bar
* Click OK
3. XP Professional
* Click Start->Settings ->Control Panel
* Click Administrative Tools
* Click Services
* Double click Services
* Scroll down and highlight "Messenger"
* Right-click the highlighted line and choose Properties.
* Click the STOP button.
* Select Disable in the Startup Type scroll bar
* Click OK
4. Windows NT
* Click Start ->Control Panel
* Double Click Administrative Tools
* Select Services-> Double-click on Messenger
* In the Messenger Properties window, select Stop
* Then choose Disable as the Startup Type
* Click OK
NOTE: If you stop the service and don’t adjust the startup type, the Messenger service will start automatically the next time you reboot. Keep in mind that when you disable the Messenger service, you'll no longer receive messages about an attached UPS, and you won’t be notified of print job completion, performance alerts, or antivirus activity (from Windows) not the program you're using for those purposes.
6. Example 6
1. To disable receipt of messenger pop-ups, verify that your firewall disables inbound traffic on UDP ports 135, 137, and 138, and TCP ports 135 and 139. On a system connected directly to the Internet, you should also disable inbound traffic on TCP port 445. If the system you want to protect is part of a Win2K-based network with Active Directory (AD), don't block incoming traffic on port 445 - Mcft Knowledge Base Article - 330904
Code:
http://support.Mcft.com/default.aspx?scid=kb;en-us;330904
NOTE: You can use the firewall approach only if your system doesn't communicate with legacy systems that rely on NetBIOS name resolution to locate machines and shared resources. If, for example, you let users running Windows 9x share your printer or scanner, when you disable inbound NetBIOS traffic, users won't be able to connect to these shared resources. Regardless of the method you choose, you can stop messenger spam
2. Program
1. Example 1
NOTE: On Oct 15, 2003, Mcft releases Critical Security Bulletin MS03-043 warning users that the Windows Messenger Service running and exposed by default in all versions of Windows NT, 2000 and XP, contains a "Remote Code Execution" vulnerability that allows any not otherwise secured and protected Windows machine to be taken over and remotely compromised over the Internet
1. Shoot the Messenger
Code:
http://grc.com/files/shootthemessenger.exe
2. Example 2
1. Messenger Disable
Code:
http://www.dougknox.com/xp/utils/MessengerDisable.zip
NOTE: If you choose to uninstall Windows Messenger on a system with SP1 installed, you will receive an error message about "un-registering" an OCX file. This is normal, and doest not affect the removal process. Windows Messenger will still be removed
3. TEST
1. Example 1
1. Right-click "My Computer"
2. Select "Manage"
3. Under "System Tools" right-click on "Shared Folders"
4. Choose "All Tasks" and select "Send Console Message..."
5. If you recieve the following error message then the service has been disabled, otherwise confirm that you have disabled it or try another example
"The following error occured while reading the list of sessions from Windows clients:
Error 2114: The Server service is not started."
2. Example 2
1. Click Start then "Run"
2. Type in {cmd.exe}
3. Type in net send 127.0.0.1 hi
4. If you get a popup "hi" message, then confirm that you have disabled it or try another example
4. IF YOU INSIST
1. If you insist on keeping Windows Messenger, then I'd recommend Messenger Manager - "Allows you to keep your messenger service running, as is intended and needed by Windows. This ensures that vital system errors and notifications may be sent informing you of Important System Events"
Code:
http://www.sellertools.com/default.asp?i=MessageManager3.htm
2. However, as a replacement to Windows Messenger remote control feature, I'd recommend this free tool Virtual Network Computing - "It is a remote control software which allows you to view and interact with one computer (the "server") using a simple program (the "viewer") on another computer anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home"

RESULTS WILL VARY
No matter how good your systems may be, they're only as effective as what you put into them.
How To Speed Up A Slow Computer
How To Speed Up A Slow Computer
first off in the bottom right hand corner of your computer if you see alot of icons start up there when you first start your computer then this is for you if you dont know already how to get rid of em.
Press your Start Button (bottom left) and go to "run"
now type in: msconfig
now you will get a box that pops up and will tell you bunch of stuff dont mess with anything else other than what I tell you otherwise you could do something really bad (possible) go to your "startup" tab on the top right of the screen where it usually is and click it.
Now you will have a closed in box with bunch of filenames n addresses and more boxes with checks in them. Now if your like me you dont want anything startin up when you start you computer up or while your even doing anything cause it slows you down. Now unless your like me right now 1 have 1 thing starting up when my computer starts up and thats my settin for my overclocked vid card. But other than that uncheck every box and then hit apply and ok. Then window you were jus in will now close and ask you if you want to restart or wait till later to restart.
Either way when you shut it off and then turn it back on the settins will kick in
How to safeguard your files when computer crashes
First thing to keep in mind: If your computer hasn't crashed yet, it will in the future! So instead of waiting for fate to strike, take some precautions now:
1) BACK-UP! Buy some decent DVD-R discs and put everything useful in them. When you have more useful stuff, backup again. Do this often.
2) Keep your computer healthy. Use an antivirus, an anti-spy, and a firewall. Keep them updated. Check regularly for Windows critical fixes.
3) Don't install software that would do dangerous things to your hard drive. A boot manager would fall in this category.
4) Use a registry cleaner before and after you install or uninstall any software. Many of the problems that will keep Windows from booting are caused by sloppy software that mess up your registry. A good registry cleaner is Tune-up Utilities.
Code:
http://www.tune-up.com/
5) Run chkdsk now and then. Go to Start> Run. Type chkdsk /F. Press enter.
In case your PC has already crashed, read the following:
Most important: Don't panic! Panic is like a little demon that whispers in your ear to format your hard drive and reinstall everything. Don't do it! You will lose all your data and the little demon will laugh at you.
To be exact you can still recover your data if you format your drive (by using special software), but only if you don't write anything on the disc afterwards. In other words format + windows install = bad idea. If you reinstall windows without formating your drive, you will only lose the files on your desktop and "My Documents" folder.
In all occasions you should make sure to safeguard your files before attempting any kind of repair!
So let's go about how to do that:
The fast way: Go to this site:
Code:
http://www.knoppix.org
. Knoppix is a Linux distribution than runs from a CD. Download the Knoppix ISO and burn it. Put it in your CD drive. On startup access BIOS and change the boot sequence so that your computer boots from the CD drive. Save settings and exit. Upon reboot, Knoppix will load.
Knoppix is much like windows and it comes with its own CD burner. Locate it, launch it and backup everything you want on CD. Now you don't have to worry anymore!
The less fast way: This requires that you have access to a second PC. Open the case of your computer and remove the hard disk.
Install it as a slave on the second PC.
Depending on respective configurations, you may have to change some jumper settings on the drive. Read the manual for help with installing hard drives and setting jumpers.
After this is done, boot the second PC. If everything went out ok, you should be able to access your drive without problems. (Edit: Note that Win98 cannot recognize a local NTFS (Win2K/XP) disk.)
Copy everything you need from your own hard drive to the other one. Now you don't have to worry anymore!
Replace your computer's hard disk, fix all problems and reverse the process to copy the data back to your computer, or take CD backups on the other PC.
