Company hopes that Apple's customers will voice their frustrations and demand Flash

Adobe's Flash supports a large portion of the internet's rich content. And it will soon be coming to almost all smart phones, opening a world of internet possibilities. All the smart phones, that is, except one of the most popular smart phones on the market -- Apple's iPhone.

Apple remains cold and aloof about the topic of Flash. While the iPhone could easily support hardware-accelerated Flash, CEO Steve Jobs has stated in interviews that Flash is irrelevant and not something that iPhone customers have demanded. He insists the iPhone is the perfect internet phone -- even if it can't run Flash.

Adobe seems to be hoping to push Apple's customers to demand the feature with a new humorously passive aggressive browser failure message.

On the iPhone customers trying to use Flash now get a message stating:

Apple restricts the use of technologies required by products like Flash Player. Until Apple eliminates these restrictions, Adobe cannot provide Flash Player for the iPhone or iPod Touch.

Before the message merely read:

To view this content upgrade your browser and flash plug-in.

Will the new message inspire users to complain to Apple, or will it merely annoy iPhone users, making Adobe look bad? It should be interesting to see how Apple's customers react to the new, more pointed error message.

Worm is first known iPhone worm, originated in Australia, may be spreading overseas

Rick Astley, an English singer-songwriter and musician, first became famous for his 1987 hit "Never Gonna Give You Up". The music industry in the 1990s gave up on Astley, but Astley didn't give up on it. He managed to recapture attention in 2007 thanks to one of the most infamous viral video crazes. Links popped up all around the internet to Astley's hit and the term "rickrolling", originally referring to tricking people into watching the video, became a common colloquialism.

Now an internet worm is achieving what Apple has been unable to do -- punish those with jailbroken iPhones (phones freed of Apple's app restrictions). Sophos, a leading security firm, appears to be the first to have investigated the amusing virus. The virus, which "rickrolls" users, changing their wallpaper to an image of Rick Astley. It appears to do little else other than spreading to other jailbroken iPhones in the user's contact list.

The worm can infect any jailbroken iPhone with SSH installed and an unchanged default password. The password on jailbroken iPhones defaults to "alpine". Users can change this by installing the MobileTerminal app, available from the Cydia undergound app store, and typing the command passwd.



Apple's hardware team can't seem to keep their close platform closed

Apple has a big headache. That headache is iPhone unlockers and jailbreakers. With iPhone jailbreaking, the powerful handsets are no longer constrained to only run the apps that Apple allows. And with unlocking, users can jump onto other networks, leaving Apple's partner AT&T and its patchy 3G network behind.

Apple has long and unsuccessfully waged war with the unlockers. It has tried to brick their iPhones. It has tried to release new firmware versions to try to lock them out. But ultimately, time and time again, Apple's best hardware and software engineers are finding themselves outwitted and befuddled by the persistent hackers.

Leading the crew is George Hotz, a 20-year-old New Jersey native who goes by the aliases geohot, million75, or mil online. When he was just a teen, he became the first to develop a procedure to jailbreak the iPhone allowing its use on other networks. The move netted him a hot car, extra iPhones, money, and fame. Now slightly older and a month out of his teenage years, Hotz continues to be among the most prolific iPhone unlockers, consistently outsmarting Apple.

Now Hotz has released his latest masterpiece, blacksn0w, a free unlocking utility that works with the latest iPhone 3G and iPhone 3GS hardware (the latest 05.11.07 baseband, which locked out previous hacks). The unlock works with a new version of Hotz's popular purplera1n jailbreak hack, dubbed blackra1n. Together the hacks can both free the phone from the AT&T network and Apple's app restrictions.


According to eBay CEO John Donahoe, shoppers have already spent about $400 million on the popular commerce site using the company’s free iPhone application.

The number pales in comparison with eBay’s total sales figure ($59.7 billion last year), but it’s fairly significant considering the fact that the iPhone has a relatively small market share – about 15% of the smartphone segment – and mobile payment transactions are still new to many. Who would have predicted around half a billion dollar in sales a year would be recorded through the eBay iPhone app when it debuted on the App Store last year?

According to this report by the Financial Times, some wealthy people have used the mobile app to buy a Lamborghini, a Bentley and a $150,000 boat. And if Mobile Marketer heard Donahoe right when he talked numbers at a summit in Las Vegas, the Lamborghini went for $350,000. Talk about being at ease with making purchases from mobile devices.

Most likely, these are the high-profile exceptions to the rule and most people use the app to buy books, clothing and electronics much like regular eBay shoppers do. In total, approximately 4.6 million iPhone owners have downloaded and installed the app to date.

t is probably a safe bet to assume anyone with a car and an iPhone has said, “man, I wish this thing could start my car.” Maybe you’ve been walking to your car on a frigid night or a scorching day, but you’ve wondered about it, haven’t you? Maybe you remember this early post from your favorite remote control blog. Viper, a leader in car security and remote starters, must have been paying attention — because they just turned that spoof into reality with Viper SmartStart for the iPhone.

SmartStart is a free iPhone app that allows you to start your car from basically anywhere via your wireless service. Now hold your horses (or Vipers) — it’s not just going to magically start your car. There is the $300 Viper SmartStart Module that you are going to have to have professionally installed in your car, as well as an annual $30 subscription to get that gear on the cell network. The first year of the service is free, so I suppose that helps. Kind of reminds me of OnStar.

Pricing aside, the SmartStart system seems pretty cool. It’s certainly the most impressive remote start system I’ve seen. First, the app can be used to start any of your cars that have the module installed — which has to be pretty helpful for car collectors and large families. You can also unlock any of your cars — from anywhere — which would definitely come in handy if you were to, say, locking yourself out of the car when you are away from home.



Apple said Thursday that it will let iPhone application developers offer their users the option to buy additional content or features within a free app on its App Store.

App developers said they received an email notice from Apple informing them that the in-app purchase feature was now available for free apps and that it would “simplify your development by creating a single version of your app that uses in App Purchase to unlock additional functionality, eliminating the need to create Lite versions of your app.” A spokeswoman for Apple confirmed the news.

The in-app purchase feature, which was first introduced in March, allows developers to offer fresh content for purchase within an app such as new levels in a game, additional books in an e-book app, or expanded capability in productivity apps. The caveat, however, was that the feature was only available for paid apps, which meant that developers had to charge at least 99 cents.

Developers say that the latest announcement helps in two ways. First, it makes it much easier for them to make a business out of free apps. Until now, developers sold ads within their free apps or tried to convert users to a paid version with more content.



After rejections, one Apple executive is trying hard to win customers -- and developers -- back

Apple's app store practices have bordered on schizophrenia, with it frequently accepting applications only to later reject them and rejecting others only to later accept them. Worse yet, frequently rejections seem to follow no consistent pattern, with some apps being rejected for containing some sort of forbidden content, while others with that same content get accepted.

These inconsistencies have led to customers growing dissatisfied with the iPhone -- or in some cases even leaving it. They have also led to a growing discontent among developers, some of whom have also jumped ship. And it has even brought down a government investigation concerning Apple's role in rejecting the Google Voice app.

However, there is one man who hopes to fix the system. Apple’s Senior Vice President of Worldwide Product Marketing Phil Schiller is trying to right the iPhone App Store and is personally taking a hand in trying to win back customers, developers, and placate government investigators.



Jailbroken iPhone users with SSH and a default password are the target

The iPhone is one of the most popular smartphones on the market. By most accounts, the iPhone is the most likely of all smartphones to be used on the internet to access files on the go. There are also a growing number of iPhone users who are jailbreaking the devices to use unauthorized Apple software or to use the devices on other carrier networks.

Over the last few weeks, a worm targeted specifically at iPhones which are jailbroken and have SSH installed with the default password was found. The original worm was nothing more than an irritation and would change the background image of the iPhone to a picture of washed up pop star Rick Astley. Embarrassing for sure, but hardly what most would consider malicious.

A similar worm targeting jailbroken iPhones with SSH and the default password -- alpine -- is making its rounds in the Netherlands. The new worm is different from the first in that the latest is clearly malicious and has a financial motive behind it for the worm maker. BBC News reports that security firm F-Secure discovered the worm and that it targets users of Dutch online bank ING. The worm infects the iPhone and redirects the user to a fake login page.

Mikko Hypponen from F-Secure told BBC News, "It's the second iPhone worm ever and the first that's clearly malicious - there's a clear financial motive behind it."

kindle booksThe Amazon store now has more than 360,000 books that you can download and read on your Kindle e-book reader.

Read Kindle Books without the Kindle Reader

If you don’t have the Kindle device, you can still enjoy any of these Kindle books on your Windows computer using the free Kindle for PC application. Amazon is also working on a Mac version of Kindle Desktop but until that happens, you can download the free Kindle app from iTunes store and read books on the move using your iPhone or iPod Touch.

Find and Download Free Books for Kindle

While most eBooks available on the Amazon Kindle store are paid, here are some simple ways by which you can find and download free books for reading on your Kindle Reader or your Kindle Desktop application.

# 1. Google Books on your Kindle

Project Gutenberg, Google Books and FeedBooks are some popular sites that offer a large collection of public domain books in the standard ePUB format.

The Kindle for PC application cannot read ePUB files directly but you can use the excellent Stanza program (from Amazon itself) to convert these public domain books from .epub into .mobi format that you can then import into Kindle Desktop for reading*. That means you now have millions of out-of-copyright books for your Kindle for free.

You can also use Stanza to convert PDFs, HTML web pages and other Office documents into .mobi format for reading inside the Kindle App but I see little reason why would anyone want to do so since the reading experience is not all that great.

# 2. Find Free Kindle Books on Amazon.com

Before your proceed, please log-in to your Amazon account, choose “Manage your Kindle” and change the country associated with your Kindle account to “United States”. This is important because most “free” content on the Kindle Bookstore is currently restricted to North America.

OK, now let’s explore ways to find free Kindle books:

# 2.1 Big Deals – This is more of an official listing of Kindle books that are currently available as a free download on Amazon.com to Kindle users. You should also check the Bestsellers category on Kindle Store as it again lists quite a good number of free titles.

free_kindle_books

# 2.2 Sort by Price – When you search for a Kindle book (or any other item) on Amazon.com, it displays search results by relevance.

If you change this default sort order from “Relevance” to “Price: Low to High”, you’ll get a list of all Kindle books that match your search keywords and are available as a free download. For instance, here’s a list of Kindle books that are related to “India” but cost exactly $0.00.

kindle_price_sort

# 2.3 Listmania - This is another resource where you can discover Kindle books that are available for free.
Listmania Lists are basically a list of products compiled by Amazon users. You can use search phrases like “free kindle books”, “kindle freebie”, “penny kindle book”, etc. to discover lists that may free books you are looking for. For instance, here’s one Listmania List of 27 classic books for Kindle that are absolutely free and here’s another one that also includes copyrighted books.

# 2.4 Use Google – Here’s an unofficial method to help you find Kindle books that are available for free on Amazon.com.

google_kindle

You can use the following search query in Google to search the Amazon store for free Kindle books – just replace the search-phrase in green with the name of the book, author, book category, etc.

intitle:kindle site:amazon.com "you save * (100%)" search-phrase
For instance, here’s a list of free Kindle books related to Abraham Lincoln while here’s a list of Kindle books on Shakespeare that are again free.

Note: Kindle Pricing for International users

If the cost of a Kindle book is mentioned as $0.00 on the Amazon Store, it will still show up as $2.00 for you if the country associated with your Kindle is something other than United States. This is because Amazon charges a $2 roaming fee for “international downloads”.

You can either temporarily change your Kindle country to US or use the “Transfer via Computer” option when buying a book and you won’t be charged that extra $2 fees. Thanks Dhamini Ratnam.

picture backupWhat’s the first thing that you do when you are back from a vacation or from a family wedding? You probably connect the digital camera to your computer and transfer the photographs (a better word would be "memories") from the camera to your hard-drive.

You’ve following this routine for quite some time and, as a result, a few hundred thousand photographs reside on your computer now neatly tagged and arranged in folders. But wait, do you have a backup plan for these "priceless" digital photos?

How to Backup your Digital Photos

There are basically four ways by which you can backup your photos at home:

1. Backup your photos on CDs and DVDs – This is a cheap and easy option but please remember that disks have a finite shelf life so pictures that you burn today on to a DVD disk may not be accessible after few years.

2. Use an external hard drive – You can get a portable 500 GB drive for less than $100, they connect to your computer via USB (or Firewire) ports but again, you can’t expect an external hard drive to last forever.

3. Use Network Storage – If you have pictures across multiple computers, you can use a network attached storage (NAS) device like HP’s MediaSmart Home Server* or Apple’s Time Capsule to automatically backup all your digital content in one place.

The HP device can transfer files to Amazon S3 so you have an added layer of protection.

4. Use an online backup services – You can use photo-sharing websites (like Flickr) or an online backup service (like Mozy) to put your photos on to the "cloud" and access them from any other computer.

For most users, the best option for preserving digital photographs is often "online backup" because it doesn’t require you to burn DVDs (which are unreliable anyway), you don’t have to invest in any new hardware and your photos are likely to last forever as long as you pay the yearly bills.

Online Backup for your Digital Photos

There are again four different routes for online backup:

# 1. Online backup services like Mozy that offer unlimited storage and allow not just photographs but files of all types.

# 2. Photo-sharing services like Flickr or Picasa Web Albums that allow you to store both photographs and video clips online.

# 3. File-synchronization services like Dropbox, SugarSync or Windows Live Mesh.

# 4. Online storage services like Amazon S3 or Windows Live SkyDrive.

What should you use?

Well, photo-sharing sites allow you to visually browse pictures in the web browser itself while a backup service like Mozy will first require you to download the photos on to the computer before you can show them to your visiting grand-parents.

File-synchronization services like Live Mesh not only provide online backup but they also save a copy of your digital files (pictures in this case) on to your other computers so even if your main hard-drive suffers a crash, you can quickly retrieve files from the other computers.

The Cost of Online Storage for Digital Photos

If you only have a few hundred photos on your computer that occupy anywhere between 1-2 GB of storage space, you can enjoy any of above backup services for free but if your storage requirements are slightly more, you probably need to for a paid version.

Now here’s a visual graph that compares the storage cost of various online backup services where you can safely store your priceless photos.

online backup for photographs

Flickr Pro costs around $25 an year and you can store unlimited number of pictures here though the maximum size of individual pictures should not exceed 20 MB (bad for professional photographs who shoot in RAW – see comments).
Picasa Web Albums on the other hand lets you purchase storage on-demand so you only pay $5 per year for 20 GB of online storage but end-up paying $100 for 400 GB of storage. Like Flickr, images uploaded to Picasa Web Albums can be no larger than 20MB and are restricted to 50 megapixels or less.
Live Skydrive is the best online storage service – it offers 25 GB of free space (50 MB limit for individual files) and that should be enough for most home users. You can upload picture libraries from your desktop to Windows Live SkyDrive using the free Windows Live Photo Gallery client though it’s only available for Windows.
Online backup services like Mozy cost around $60 per year respectively but here you get unlimited storage, your files are automatically backed up (in the background) and there are no restrictions on file-size.
SmugMug, another popular photo-sharing site, offers a service called SmugVault that uses Amazon S3 to backup your photos, videos and all other file-types that you can imagine. They have a relaxed 600 MB per file limit and you pay the normal Amazon S3 rent for files that are not photos.
Amazon S3, where you pay only for what you use, is very reliable (their SLA promises 99.9% uptime) turns out to be very expensive if your yearly storage requirement exceeds 10 GB.

online photo storage prices

Here’s another representation of the same graph – Yearly costs (in $) vs. storage offered (in GB).
Windows Live SkyDrive offers 25 GB of online storage space for your pictures for free though there’s no option to purchase extra storage. In paid services, Google’s Picasa offers the best value for money if your photo collection can fit in 20 GB else a Flickr Pro account probably makes more sense.

Picasa desktop software makes it easy for you to upload and download photos from Picasa Web Albums. Flickr provides an uploading utility but you need to rely on a third-party hacks to download the original (full-resolution) albums from Flickr.

A hard disk drive (HDD), commonly referred to as a hard drive or hard disk, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, “drive” refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit with fixed media… 1

If your computer is running a fairly new operating systems, such as Windows XP, Vista or even Mac OS X, chances are that it won’t be able to play any of the old DOS games that were originally designed for 16-bit systems.
There are however simple workarounds that will help you play your favorite DOS games on any modern computer just the way they worked on old 486 machines of the 90’s. The other good part is that you can download most popular DOS games from the web for free and legally.

Play Old DOS Games on your Computer

The easiest way to run DOS games on your computer is through DOSBox.

aladdin - DOS games mario bros in DOS

DOSBox, in simple English, is a free program that emulates an X86 based DOS environment on your new computer including speaker sounds, video graphics and other hardware. DOSBox is available for Windows, Linux and Mac OS X so you can practically use it to run DOS games on practically every computer.

You can simply install DOSBox via the command line but if that sounds too technical, there are graphical frontends for DOSBox that will let you run DOS programs through a simple GUI.

One of the most popular GUI frontends for DOSBox is D-Fend Reloaded. You can install this program like any other Windows application and it is ready for use immediately after the installation. To install a DOS game, simply use the import wizard or drag-and-drop the zip archive file (that contains the DOS program) into the D-Fend Reloaded window.

D-Fend Reloaded also offers game packages, containing both freeware and shareware DOS games, that you may install on your computer at once using a simple installer. You can play these classic games using DOSBox without having to configure anything.

Build an MS-DOS Virtual Machine for Playing Games

Doom DOS Game If the requirements are such that DOSBox emulators are unable to run your favorite DOS game, you can try running DOS inside a virtual machine using virtualization software like Windows Virtual PC, VMWare Player, or VirtualBox from Sun – they are all free solutions.

Microsoft offers a free copy of MS-DOS operating system that you may convert into a virtual machine or you can download the FreeDOS program from the Internet which is just like MS-DOS and completely free.

Once you have a virtual machine running DOS, you need a way to install DOS programs into the virtual machine. This can be done by burning a CD image of the DOS games and then attaching that CD image to the virtual machine.

Play DOS Games Online in the Browser

The installers for DOS games were initially distributed on floppy disks and the game authors may have never envisioned that people would be playing these games though the Internet without installation but that is exactly what you can do today.

JPC is a Java-based x86 emulator that can run some DOS programs on any modern browser with the Java plugin. The JPC site hosts a couple of popular DOS games including DOOM and Mario Brothers but for a more extensive collection, you should check out Classic DOS Games. The sites currently has 169 different games that you can play directly in any web browser that has the Java plugin installed.

JPC based DOS games may not run as fast as their DOSBox counterparts but there’s one advantage – you can try a game online before deciding if you want to download a copy to your hard drive.

Download DOS Games from the Internet

Now that you have everything in place to run DOS games on the computer, you are most definitely looking for some great games to play with.

Here are some popular sites where you can find and download most of your favorite DOS games, but since too many choices can be confusing, check this search engine that will help you search all the popular PC games’ websites from one place.

1. DOS Games – With over 500 classic titles, DOSGames.com is a great place to look for your favorite DOS games. You can run these games using the free DOSBox emulator discussed above. The site is actively updated so it is likely that more games will be added over time.

2. DOS Games Archive – DOS Games Archive is another useful site with a very large collection of DOS games. The sites provides screenshots of the DOS games, user ratings, violence ratings, cheat codes and you can also find out if a particular game is supported on DOSBox. Many of the games listed on the site were commercial games that were later released for free by the game publisher.

3. D-Fend Game Packages – If you chose to install D-Fend Reloaded with DOSBox, then you can easily access hundreds of classic DOS games using this easy installer. Each game package contains a collection of about a dozen or so games of the same category and you can have them all on your machine with a click.

4. Classic DOS Games – This site also contains a wide range of DOS games categorized by their Genre, Company, Year Released, etc. All DOS games listed on this site are freely distributable because they are shareware, freeware, or because the copyright holder has officially and legally released all rights to the public domain.

5. Good Old Games – This site specializes at re-releasing classic commercial games for modern PCs at reasonable prices. Their selection includes many popular DOS-based games that are packaged with DOSBox for a seamless game experience on Windows Vista and XP. If your looking for a commercial game that has not been released as freeware, this may be the best place to look for it.

6. Abandonia – As the title suggests, this site has a very collection of games that are under the category of “abandonware” or titles that are no longer sold /developed by the authors.

7. Home of the Underdogs – One of the most popular abandonware sites with reviews of over 5,300 games for DOS and Windows. Other than game binaries, the sites also offers manuals for a number of games that are no longer commercially available.

For offline reference, you may download this catalog of DOS games from Wikipedia that possibly includes every DOS title that has been released till date.

screen capture with paint

PicPick is an useful Windows utility that includes a decent screen capture program, a Paint like image editing software and a whiteboard tool to help you draw freehand on the desktop using your mouse (handy when you are giving presentations).

During screen capture, you can select the "Capture Window Control" mode and capture objects that extend multiple screens (like a long Word document or a lengthy web page). And like SnagIt, PicPick can send screenshot images directly to another programs after capture or it can automatically upload them to an FTP server.

Portable Image Editor

portable image editing program

The image editor included with PicPick sports an Office 2007/2010 like ribbon interface and supports tabs so you can edit multiple screenshot images / photographs from the same window.

If you are a web designer, you can use the built-in crosshair tool to determine the coordinates of any point on the desktop screen or for capturing the exact dimensions of an object (in pixels).

And since the software doesn’t require installation, you can put it on a USB drive and use it on any computer.


Let’s assume you have two computers at home and you want to connect them together so that you can easily share an internet connection between the two machines or transfer photos, music and other files from one computer to another. How do you do this?

Connect Two Computers Directly

There are two options – you can either buy a router or, if you are looking for something more simple and don’t want to spend money on new networking hardware, you can connect the two computers using a commonly-available cable. The latter method doesn’t involve any complicated network settings and you will still be able to share files, internet connection, and even printers between computers.

Things you need:
To set up this basic wired home network, all you need is an inexpensive Ethernet crossover cable and the other requirement is that network cards* (also known as LAN or Ethernet cards) should be installed on each of you computers.

This should not be an issue because network cards are available on most newer machines by default but if you are working with a very old computer, you can either attach an internal LAN card to your computer’s motherboard or go for a USB Network adapter that will turn a USB port into an Ethernet (RJ45) port.


Ethernet Cables for Connecting Computers



An Ethernet crossover cable looks like a standard Ethernet cable but the internal wiring is a little different. You can purchase crossover cables at Amazon.com or from your local computer store. If you have trouble finding them, you can purchase an inexpensive crossover adaptor and that will let you use any standard Ethernet cable as a crossover cable.

Connect Computers with an Ethernet Crossover Cable

Before connecting the two computers with a physical cable, make sure that both machine are using the same workgroup*. Here is step-by-step guide that explains how you can change the workgroup of your computers.
Changing workgroup in Windows XP – From the Start menu, right-click “My Computer.” Select Properties in the drop-down menu, and then select the second tab that says “Computer Name” from the System Properties window. Now click the “Change…” button, enter a unique Workgroup name and reboot your computer.

1. My Computer - Properties 2. Change Workgroup Name 3. Save Workgroup Name and Reboot

Changing workgroup in Windows 7 or Vista – Open the Control Panel, type “Workgroup” in the search box, and select the entry that says “Change Workgroup Name.” Click the “Change…” button, enter a Workgroup name and restart the computer. Windows 7 users can skip one step; simply type “Workgroup” in the search box in the start menu, and select the first entry, then proceed as above.

1. Search Workgroup from Control Panel 2. Change Workgroup - Vista or Windows 7 3. Assign Workgroup Name

Now that the workgroups are same for both computers, connect the two computers together using the Ethernet crossover cable. Simply plug-in one end of the crossover cable into the network adapter of Computer A and connect the other end of the cable to the network adapter of Computer B.
Windows will automatically recognize the new network, and you can now easily view files and folder that the other computer has shared. Simply open Networks from the Start Menu (or the Control Panel), and you should see the other computer by its name. You can then browse any shared files on the other computer, and can even utilize shared printers.

Troubleshooting – If you do not see the other computer under Networks, you probably have a prompt at the top of your Network window saying that Network discovery is turned off (screenshots below). Select “Turn on Network Discovery and File Sharing.” In the next prompt, select “No, make the network I am connected to a private network.” Now you should see the other computer on the home network.

1. Turn on network discovery 2. Turn Off File Sharing for Public Networks

While it is possible to share files between two computers connected with a crossover cable without making them part of the same workgroup, the method will only work if both computers have this network set as a private network, and may still cause problems. It is therefore advisable to have both computers on the same workgroup before sharing files and printers.

Share an Internet Connection Between Two Computers

There are scenarios where you may want to share the same internet connection between two computers. For instance:

Situation A - You have setup a Wi-Fi network at home but your old desktop computer doesn’t have a wireless network card. In that case, you can use the laptop to connect to the internet wirelessly and then share that same connection with the desktop over a crossover Ethernet cable.

Situation B – You have a netbook with a built-in cellular data connection. You can share that connection with any another computer at home through the crossover Ethernet cable.

Situation C – You use a (slow) Wireless USB modem with your laptop computer while your desktop is connected to an ADSL Broadband line and there’s no router at home. For any bandwidth intensive tasks, like when you want to backup photos from your laptop to an online service, you can connect the laptop to the desktop and things will happen much faster.

OK, let’s look at the steps required for sharing an Internet connection.
First, if you only wish to share internet connection and not files, both computers need not belong to the same workgroup. All you need to do is to connect the two computers with the Ethernet crossover cable, and then turn on Internet connection sharing in the computer that already has an Internet connection. The instructions vary for different versions of Windows:

For Windows XP – Select “Network and Internet Connections” from the Control Panel and click “Network Connections.”

1. Network and Internet Connections 2. Change Network Connection Properties 3. Allow Internet Connection Sharing

Right-click on the network connection you wish to share (the one connected to the internet), select Properties, click on the “Advanced” tab, and then check the box that says “Allow other network users to connect through this computer’s Internet connection.” Click OK, and the second computer that you have connected to this computer with the Crossover Cable should have internet access now.

For Windows 7 and Vista – Open Control Panel, enter “network connections” in the search box on the top right and select “View Network Connections.”

Vista - Share internet connection 1 Vista-7 - Share Internet Connection 2 Vista-7 - Share Internet connection 3

Right-click on the network connection you wish to share (this must be the one connected to the internet) and select Properties. Select the "Sharing" tab and then check the option that says “Allow other network users to connect through this computer’s Internet connection.” Click OK, and the other computer you have connected to this Windows 7 or Vista computer should have internet access now.
