How To Lock Your Computer With USB Drive

Tired of people starting your computer when you are not around and messing up custom settings? Wouldn’t it be cool if you could lock your computer by just removing your USB stick from it? I’ll show you how you can use your USB stick, Flash Drive or Pen Drive what ever you call it to lock your computer, among other things…

Boot Lock
 

This trick will allow you to use your USB to BOOT into Windows. If someone tries to start the computer without your USB stick, it will display boot errors. Before begin, you playing with the BIOS and boot files of your computer may result in you not being able to boot into your Windows partition; so continue at your own risk! 

Things you need: A 64MB or larger sized USB Stick, Windows Recovery Disk (just in case). Unhide hidden and protected files : Go to Tools > Options > View, check Show hidden files and un-check Hide protected system files.

• From the drive where Windows is installed (normally C:\), copy the files boot.ini, ntdlr and NTDETECT.COM to your USB Stick.
• Now, we need to go into your BIOS, so restart the computer and keep jabbing [F8] as soon as the computer starts.
• Once in the BIOS, enable USB Drive as the first boot device. You might have to enable USB Legacy  Support on older BIOSes.
• Restart your computer, if all goes well, you should be able to log into Windows. If not, then unplug the USB Stick, return to the BIOS and change the First Boot device to your hard disk drive and repeat the steps above.
• Once you are logged into Windows, go to your Windows drive and rename boot.ini to boot.bak.
• To check if you have setup everything correctly, eject your USB stick and reboot the computer. You should get error messages on the screen such as Invalid Boot.ini” or “Windows could not start”.

That's it !   :)

Megabytes, Gigabytes, Terabytes... What Are They?

These terms are usually used in the world of computing to describe disk space, or data storage space, and system memory. For instance, just a few years ago we were describing hard drive space using the term Megabytes. Today, Gigabytes is the most common term being used to describe the size of a hard drive. In the not so distant future, Terabyte will be a common term. But what are they? This is where it gets quite confusing because there are at least three accepted definitions of each term.

According to the IBM Dictionary of computing, when used to describe disk storage capacity, a megabyte is 1,000,000 bytes in decimal notation. But when the term megabyte is used for real and virtual storage, and channel volume, 2 to the 20th power or 1,048,576 bytes is the appropriate notation. According to the Microsoft Press Computer Dictionary, a megabyte means either 1,000,000 bytes or 1,048,576 bytes. According to Eric S. Raymond in The New Hacker's Dictionary, a megabyte is always 1,048,576 bytes on the argument that bytes should naturally be computed in powers of two. So which definition do most people conform to? 

When referring to a megabyte for disk storage, the hard drive manufacturers use the standard that a megabyte is 1,000,000 bytes. This means that when you buy an 80 Gigabyte Hard drive you will get a total of 80,000,000,000 bytes of available storage. This is where it gets confusing because Windows uses the 1,048,576 byte rule so when you look at the Windows drive properties an 80 Gigabyte drive will report a capacity of 74.56 Gigabytes and a 250 Gigabyte drive will only yield 232 Gigabytes of available storage space. Anybody confused yet? With three accepted definitions, there will always be some confusion so I will try to simplify the definitions a little. 

The 1000 can be replaced with 1024 and still be correct using the other acceptable standards. Both of these standards are correct depending on what type of storage you are referring.

Processor or Virtual Storage	Disk Storage
· 1 Bit = Binary Digit · 8 Bits = 1 Byte · 1024 Bytes = 1 Kilobyte · 1024 Kilobytes = 1 Megabyte · 1024 Megabytes = 1 Gigabyte · 1024 Gigabytes = 1 Terabyte · 1024 Terabytes = 1 Petabyte · 1024 Petabytes = 1 Exabyte · 1024 Exabytes = 1 Zettabyte · 1024 Zettabytes = 1 Yottabyte · 1024 Yottabytes = 1 Brontobyte · 1024 Brontobytes = 1 Geopbyte	· 1 Bit = Binary Digit · 8 Bits = 1 Byte · 1000 Bytes = 1 Kilobyte · 1000 Kilobytes = 1 Megabyte · 1000 Megabytes = 1 Gigabyte · 1000 Gigabytes = 1 Terabyte · 1000 Terabytes = 1 Petabyte · 1000 Petabytes = 1 Exabyte · 1000 Exabytes = 1 Zettabyte · 1000 Zettabytes = 1 Yottabyte · 1000 Yottabytes = 1 Brontobyte · 1000 Brontobytes = 1 Geopbyte

This is based on the IBM Dictionary of computing method to describe disk storage - the simplest.

Now let's go into a little more detail.

Bit: A Bit is the smallest unit of data that a computer uses. It can be used to represent two states of information, such as Yes or No.

Byte: A Byte is equal to 8 Bits. A Byte can represent 256 states of information, for example, numbers or a combination of numbers and letters. 1 Byte could be equal to one character. 10 Bytes could be equal to a word. 100 Bytes would equal an average sentence.

Kilobyte: A Kilobyte is approximately 1,000 Bytes, actually 1,024 Bytes depending on which definition is used. 1 Kilobyte would be equal to this paragraph you are reading, whereas 100 Kilobytes would equal an entire page.

Megabyte: A Megabyte is approximately 1,000 Kilobytes. In the early days of computing, a Megabyte was considered to be a large amount of data. These days with a 500 Gigabyte hard drive on a computer being common, a Megabyte doesn't seem like much anymore. One of those old 3-1/2 inch floppy disks can hold 1.44 Megabytes or the equivalent of a small book. 100 Megabytes might hold a couple volumes of Encyclopedias. 600 Megabytes is about the amount of data that will fit on a CD-ROM disk.

Gigabyte: A Gigabyte is approximately 1,000 Megabytes. A Gigabyte is still a very common term used these days when referring to disk space or drive storage. 1 Gigabyte of data is almost twice the amount of data that a CD-ROM can hold. But it's about one thousand times the capacity of a 3-1/2 floppy disk. 1 Gigabyte could hold the contents of about 10 yards of books on a shelf. 100 Gigabytes could hold the entire library floor of academic journals.

Terabyte: A Terabyte is approximately one trillion bytes, or 1,000 Gigabytes. There was a time that I never thought I would see a 1 Terabyte hard drive, now one and two terabyte drives are the normal specs for many new computers.  To put it in some perspective, a Terabyte could hold about 3.6 million 300 Kilobyte images or maybe about 300 hours of good quality video. A Terabyte could hold 1,000 copies of the Encyclopedia Britannica. Ten Terabytes could hold the printed collection of the Library of Congress. That's a lot of data.

Petabyte: A Petabyte is approximately 1,000 Terabytes or one million Gigabytes. It's hard to visualize what a Petabyte could hold. 1 Petabyte could hold approximately 20 million 4-door filing cabinets full of text. It could hold 500 billion pages of standard printed text. It would take about 500 million floppy disks to store the same amount of data.

Exabyte: An Exabyte is approximately 1,000 Petabytes. Another way to look at it is that an Exabyte is approximately one quintillion bytes or one billion Gigabytes. There is not much to compare an Exabyte to. It has been said that 5 Exabytes would be equal to all of the words ever spoken by mankind.

Zettabyte: A Zettabyte is approximately 1,000 Exabytes. There is nothing to compare a Zettabyte to but to say that it would take a whole lot of ones and zeroes to fill it up.

Yottabyte: A Yottabyte is approximately 1,000 Zettabytes. It would take approximately 11 trillion years to download a Yottabyte file from the Internet using high-power broadband. You can compare it to the World Wide Web as the entire Internet almost takes up about a Yottabyte.

Brontobyte: A Brontobyte is (you guessed it) approximately 1,000 Yottabytes. The only thing there is to say about a Brontobyte is that it is a 1 followed by 27 zeroes!

Geopbyte: A Geopbyte is about 1000 Brontobytes! Not sure why this term was created. I'm doubting that anyone alive today will ever see a Geopbyte hard drive. One way of looking at a geopbyte is 1₅267 650₄600 228₃229 401₂496 703₁205 376 bytes!

Now you should have a good understanding of megabytes, gigabytes, terabytes and everything in between. Now if we can just figure out what a WhatsAByte is......:)

43. If you’re worried your computer might crash and you’ll lose all your music, you can back it up to an online MP3 file storage service like MP3Tunes. What’s cool about this rather than just backing up music files onto a USB hard drive is that you can access your media files from anywhere via streaming.

44. If you’ve recently bought a new computer, you can use a program called PC Decrapifier to get rid of all those useless programs that can come bundled with the PC and slow everything down.

45. After you have a computer for a while, there are always going to be programs that you don’t use anymore and that can be uninstalled. Revo Uninstaller will get rid of any program whether it likes it or not.

46. Even if you use Google for searching the Internet, there are many times when a site listed in the top 10 results is spammy or contains malware. However, I always like using extra tool such as WOT (Web of Trust) or McAfee SiteAdvisior to protect myself when browsing the Internet.

47. If you have sensitive data on your computer that you want to permanently delete from your hard drive, I would suggest using a program called Eraser.

How does Facebook Make Money ?

They say its free. They also say that Mark Zuckerberg – the guy who started Facebook – is one of the richest people around – a billionaire apparently. So how the hell does this guy give free accounts to its users and yet sit happily atop a goldmine? The figures going around about Facebook's annual revenue are heart-stopping to say the least. The numbers that did the rounds were all around the US$ 500 million mark, which means that since 2007, they've been more or less doubling their revenue. All this from a free website! So where is the money coming from? This article will answer the question, how does Facebook make money and solve the mystery for you.

How Facebook Makes Money?

Free account notwithstanding, Facebook is making money. And lots of it. How does Facebook make money? If only you knew how does Facebook work financially!

Ads

I'll solve the mystery for you in one simple word – ads. The same thing that runs most websites across the world. That is the big secret behind Facebook's burgeoning revenue. If you open your Facebook profile, you will see that the while right hand side of the page is full of ads. You can give the thumbs up to the ad or the thumbs down. The thumbs down will remove the ad and it will not come back.

How do these ads work? Well Facebook being a decidedly smart social networking institution knows which ad to put where. Like the Google AdSense, Facebook too provides ad to the pages based on the interests and the overall profile of the user. So, if you mention in your profile that you are a fan of Nike or any other sportswear brand, the related ads will appear on the right hand side of the page for companies and websites selling them. Facebook ads are not intrusive and hence people do not get annoyed with them, unlike we do with those super-irritating pop-up ads.

And their advertising system makes sense, since it ensures that the right ad is displayed to the right customer, since the ads are selected for an individual page based on the interests and likes of the user. This avoids unnecessary waste of adspace on the page where the chances of the ad being 'hit' are theoretically pretty low. Also, the ad system of Facebook, gives the user a 'thumbs down' option, which ensures that the particular ad does not appear again. That too is a pretty interesting thought, given that the ad hasn't a chance of being clicked and letting it sit in front of the users will continue to rile them.

Facebook Gifts

Ever sent a virtual gift on someone's birthday? You must have at some point, if you knew how to use Facebook. Well you do pay for some of them and a big slice of it goes into coffers of the company. While simply writing 'happy birthday' suffices for some, the 'send a gift tab' on your friend's wall encourages others to send a virtual gift – paid for online. All the money almost always goes to the company, but if the gift is provided by an outsider, then a portion of it goes there. But much of it is still retained by the website.

Application Performance

The beautiful thing about companies like these which work on different platform are the plethora of business ideas that they bring to the table. Performance advertising is a unique answer to how does Facebook make money. Let us take the example of Farmville, which is doing reasonably well on Facebook. Now the application is provided free for use for the users of Facebook and the parent company (Zynga) is getting a lot of traffic because of the game's popularity on Facebook. So isn't Facebook entitled to take a slice of that pie? After all, they are providing a platform for gaming companies like Zynga to their burgeoning user base. So Facebook makes a bit of money there too, as a 'rental' for using their users.

I guess that answers your questions about what is Facebook and how does it work and how does Facebook make money. Now this information on how Facebook makes money is largely speculative. Facebook is a privately held company and has the complete liberty to not disclose their financial details – and they don't disclose their revenues and the sources of their revenues either.

99 ways to make your computer blazingly fast

Over the last several years working in IT for various companies as a Systems Administrator, Network Administrator, and Help Desk professional, I’ve written and learned about many ways to increase the performance of not only my PC, but also of the many PCs on my networks ranging from Windows 98 to Windows Vista.

In this article, I hope to compile a complete list of all the different methods and tricks that I’ve used to get the last bit of juice out of a slow PC. Whether you are using an old PC or the latest and greatest in hardware, you can still use some of these to make your PC run faster.

Note that since I write two blogs, Help Desk Geek and Online Tech Tips, I have previously written about many performance tips already which I will link back to throughout. If I have not written about it, I’ve throw in a link to a relevant article from some of my other favorite sites. This list is in no particular order, just written in the order that I could think of them.

There are probably a lot of great tweaks and performance hacks that I’ve missed here, so feel free to chime in with comments! Enjoy!

1. Defragment your computer hard disk using free tools like SmartDefrag.

76. Disable short filenames if you are using NTFS by running the following command: fsutil behavior set disable8dot3 1. It will speed up the file creation process.

77. If you have lots of files in a single folder, it can slow down Explorer. It’s best to create multiple folders and spread out the files between the folders.

78. If you have files that are generally large, you might want to consider increasing the cluster size on NTFS to 16K or even 32K instead of 4K. This will help speed up opening of files.

79. If you have more than one disk in your PC, you can increase performance by moving your paging file to the second drive and formatting the volume using FAT32 instead of NTFS.

80. Turn off unnecessary features in Vista by going to Control Panel, choosing Uninstall a program, and then clicking on Turn Windows features on and off. You can turn off Remote Differential Compression, Tablet PC components, DFS replication service, Windows Fax & Scan, Windows Meeting Space, and lots more.

85. Remove the drivers for all old devices that may be hidden in Device Manager that you no longer use.

86. A more extreme option is to choose a faster operating system. If you find Vista to be slow, go with Windows XP. Switching to Mac or Linux is also an option.

87. One of the easiest ways to speed up your PC is to simply reformat it. Of course, you want to backup your data, but it is the best way to get your computer back to peak performance.

88. Speed up Internet browsing in IE by increasing the number of max connections per server in the registry.

89. If you use uTorrent to download torrents, you can increase the download speeds by tweaking the settings.

90. If you have a desktop background, make sure it’s a small and simple bitmap image rather than a fancy picture off the Internet. The best is to find a really small texture and to tile it.

91. For the Virtual Memory setting in Windows (right-click on My Computer, Properties, Advanced, Performance Settings, Advanced, Virtual Memory), make sure the MIN and MAX are both the same number.

92. If you search on Google a lot or Wikipedia, you can do it much faster on Vista by adding them to the Vista Start Menu Instant Search box.

93. If you have a custom built computer or a PC that was previously used, make sure to check the BIOS for optimal settings such as enabled CPU caches, correctly set IDE/SATA data transfer modes, memory timings, etc. You can also enable Fast/Quick boot if you have that option.

94. If you have a SCSI drive, make sure the write cache is enabled. You can do so by opening the properties of the SCSI drive in Windows.

95. If you have a machine with an older network card, make sure to enable the onboard processor for the network card, which will offload tasks from the CPU.

96. If you are using Windows Vista, you can disable the Welcome Center splash screen that always pops up.

97. If you already have anti-spyware software installed, turn off Windows Defender protection.

98. If you are running a 32-bit version of Windows and have 4GB of RAM or more, you can force Windows to see and use all of the RAM by enabling PAE.

99. Buy a new computer!!! ;) Pretty easy eh?

I’m sure I have missed out on lots of performance tweaks, tips, hacks, etc, so feel free to post comments to add to the list! Enjoy!

Partition a USB Flash Drive in Windows XP

One way to Partition a USB Flash Drive from Windows XP and mark it active "bootable". Windows detects Flash Drives as "Removable Disks" and flash drives are typically shipped formatted as a "Super Floppy" (USB-FDD without a partition table) . The Windows built in format utility cannot create a partition table on Removable Disks. Furthermore, the diskpart utility in Windows XP will not allow you to partition Removable Media, although diskpart does work for partitioning a Flash Drive from Windows Vista/7.

To address the inability to Partition a Flash Drive in Windows XP, you need to use a third party low level partitioning tool such as BOOTICE, created by Pauly. BOOTICE Home Page

Note: I partition my flash drives as USB-HDD (with a partition table), simply because my computers support booting from Flash Drives formatted to be seen as a USB Hard Disk.

One way to Partition a Flash Drive from Windows

1. Download BOOTICE, unzip, and run BOOTICE.EXE
2. Make sure your "USB Flash Drive" is set as the Destination Disk
3. Click Parts Manage 
4. Click ReFormat USB Disk
5. Select USB-HDD mode, and click Next 
6. Select Format as Fat32, and click OK

FIGURES :

You should now have an active "bootable" USB-HDD Fat32 formatted Flash Drive, containing a partition table with a single partition. You should be able to Boot It as a Hard Drive.
