How to speed up Firefox

Here's How: 1. Open the Firefox "config" page: click into the Firefox address location bar, and type about:config , press Enter. 2. The "Config" file will appear in the Firefox browser as a page with hundreds of lines of code in it. Now, we start by enabling some advanced tabbed options:
		3. Locate the line browser.tabs.showSingleWindowModePrefs . (tip: press "b" on your keyboard to quick scroll). 4. Double click on browser.tabs.showSingleWindowModePrefs (only for versions older than Firefox 1.5). This will set its toggle to "true". Now your advanced and enhanced tabbing should be set. 5. Next: we will increase the "pipeline" RAM ability for Firefox to accomodate more packet transfer. In the same config document, scroll down to the line that says network.http.pipelining . Double click this line to set it to "true". Find network.http.proxy.pipelining and set it to "true". 6. Lastly, we will increase the maximum pipeline requests to 100. Find the line that says network.http.pipelining.maxrequests . Double click on it, and a dialog box will pop up. Change the setting from 4 to 100. 7. No need to save this file. Simply close and restart Firefox, and you should see an immediate 10% to 40% increase in web page transfer speed, and faster opening of your tabbed windows! Enjoy!

Macs run Office.

These days, who doesn’t use Microsoft Office at least some of the time? People all over the world use Excel, PowerPoint, and Word. On Macs, too.

With Microsoft Office 2004 for Mac OS X, you too can create documents with Word, presentations in PowerPoint, and spreadsheets with Excel with the same features and shortcuts you’ve been using on your Windows PC — so you won’t have to re-learn a thing. Plus you’ll enjoy virtually flawless compatibility with Microsoft Office for Windows, so you can easily share documents with friends and colleagues.

You’ll even notice a few things in Office for Mac not available in the Windows version. For example, a Project Center helps you be more efficient by putting all of your project-related email messages, files, notes, contacts, and schedules in one convenient place. You can also take full advantage of Mac OS X Tiger’s powerful Spotlight search, which indexes file names, metadata, and even the content inside your Office documents; with one search, you can quickly find the exact document you’re looking for even if you don’t know what it’s called or when you wrote it.

Office for Mac also includes a powerful e-mail program: Entourage. It handles e-mail messages, contacts, schedules, notes, documents, and more from one central location. And if your organization uses an Exchange Server, no problem: support is already built into Entourage 2004. Other Microsoft applications such as Windows Media Player and MSN Messenger are available for the Mac, as well. Mac OS X also supports many proprietary protocols, file formats, and other Microsoft-specific technologies that enable Macintosh computers to be used with Active Directory and Microsoft’s VPN server. Of course, any program that’s not yet available for Mac — such as Microsoft Access or Project — can still run on your Intel-based Mac using Boot Camp

Windows XP Tips for Computer Security

by: Chris Kaminski

Here are a couple of tips to speed up your Windows XP computer and help keep you protected and secure online. First you need to control which programs load on startup: Many of the programs you install on your computer automatically configure themselves to launch at startup, usually invisibly. The truly essential ones, such as anti-virus and firewall products, generally run as services and run fine in the background. Other less important software like media players don't need to be running continually.

These extra programs slow the boot process and then severely suck up resources like memory and CPU cycles. It is pretty easy to control which applications launch on startup. The System Configuration Utility lists all these applications in one place:

1) To get there: Click the ‘Start' button then choose the ‘Run' command.

2) In the text box type "msconfig". - Across the top of the dialog box select the ‘Startup' tab.

3) The Startup Tab lists all the programs that launch at start-up. To disable any of these simply un-check the box on the left. Only non-essential programs are listed here it should be safe to un-check pretty much anything. If it turns out you needed it just go back and re-check it.

4) Once you are done re-boot the machine. 5) When the Desktop returns you will be presented with a window that says you have chosen Selective Startup. Just Check "Do not show this window again" and click OK.

To keep your computer secure, turn on automatic updates. Seems like every virus writer has nothing better to do then attack Windows operating systems. Keeping the system patches and security fixes is critical. During the setup of XP Service Pack 2 with a new computer or an up-grade you are asked whether or not to turn on automatic updates, if you made the mistake of checking no you can find this option in the Windows Security Center (Start / Control Panel) and change it back. Even with all its faults, XP is a powerful operating system that has many good security features.

Here are some more tips to help you get the most out of your operating system. Remove Windows components not found in ADD / REMOVE. Many Windows components, things like Network Services or Solitaire are easy to remove through the Add or Remove programs configuration window (Start / ControlPanel / Add and Remove Programs / Windows Components). Simply un-check them, but … some things are deliberately hidden.

A good example would be MSN Messenger. To remove this from startup follow these steps:

1) In Windows Explorer (right click Start / Explore), navigate to C:WindowsInf and make a copy of Sysoc.inf.

2) Double click on Sysoc.inf and it will open in Notepad.

3) Press Ctrl H (opens Find and Replace) and replace the string ,hide, with ,, then save and replace the file. Now all the hidden components will appear.

4) Then follow the steps above for removing programs from the startup menu.

To restore a corrupted system file: If a necessary system file should become missing or corrupted by a virus you can replace it from your Windows CD.

1) Go to Start / Search and type in the file name replacing the last letter with an underscore (ex. Filename.ex_).

2) If the file is found, open a command prompt (Start / Run, type CMD in the textbox).

3) At the prompt type expand followed by the full pathname of the file and destination (expand D:Windowsfilename.ex_ C:Windowsfilename.exe) where D: is the letter of your disc drive. If either pathname contains spaces surround the entire pathname with double quotes. If the file isn't found search again using the un-modified file name, it is probably in a CAB file, Windows treats these as folders, simply drag the new folder to the destination while holding down the right mouse button then select Copy Here.

History Of computer

Main article: History of computing

The Jacquard loom was one of the first programmable devices.
The Jacquard loom was one of the first programmable devices.

It is difficult to define any one device as the earliest computer. The very definition of a computer has changed and it is therefore impossible to identify the first computer. Many devices once called "computers" would no longer qualify as such by today's standards.

Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers.

However, none of those devices fit the modern definition of a computer because they could not be programmed. In 1801, Joseph Marie Jacquard made an improvement to the textile loom that used a series of punched paper cards as a template to allow his loom to weave intricate patterns automatically. The resulting Jacquard loom was an important step in the development of computers because the use of punched cards to define woven patterns can be viewed as an early, albeit limited, form of programmability.

In 1837, Charles Babbage was the first to conceptualize and design a fully programmable mechanical computer that he called "The Analytical Engine".[2] Due to limited finance, and an inability to resist tinkering with the design, Babbage never actually built his Analytical Engine.

Large-scale automated data processing of punched cards was performed for the US Census in 1890 by tabulating machines designed by Herman Hollerith and manufactured by the Computing Tabulating Recording Corporation, which later became IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of practical computers had begun to appear: the punched card, boolean algebra, the vacuum tube (thermionic valve) and the teleprinter.

During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility and accuracy of modern digital computers.
