Chromebooks went for sale in June and in this short period of time, Samsung has already dropped the price of their Google Chrome OS laptops by as much as 10%.

Generate Strong Passwords with Wolfram

Wolfram Alpha – an online engine that in some respects is more powerful than Google – can also be used for generating strong and unique passwords for your various online accounts.
To get started, go to the wolframalpha.com website and type a natural-language query like password of n characters to create your unique password (n is the length of the password).

Unlike other password generators, Wolfram Alpha offers a phonetic form for every password to make it a bit easier for you to memorize that complex string. It also shows the time it would take for a computer to break that particular password.

HTTPS and VPN Explained in Simple English

Improve your Website Images with Rich Tooltips

Some parts of this article may not render correctly in your RSS reader. Please click here to read the full version.

Web designers have long used image maps in HTML to link different areas of an image to different web pages. For instance, what you see above is a single image of some well-known people and if you click on any of the faces, you'll be transported to their respective sites.
Larry's image links to his Wikipedia entry, Sergey's face will take you to one of his video lectures on YouTube while Eric's image is linked to his Twitter account. One image but with multiple links and all pointing in different directions. The previous chart, illustrating the most disliked videos on YouTube, also uses an Image Map.

Rich Tooltips - An Alternative to HTML Image Maps

Image Maps are useful and easy to implement but have certain drawbacks.
You don't get any clues about the page that an image area is linking to until you actually click the link. The other downside is that you need to hover your mouse over the full image in order to to identify which parts of that image are clickable.
Now let's try something different. I have embedded the same collage below but instead of using HTML based Image Maps, it uses Thinglink, an online tool  that makes your static web images interactive with rich tooltips. Hover your mouse for a quick demo:

Like an Image Map, you define an area on the image that you would like to link to the other site. In Thinglink's jargon, these are known as hotspots. When users hover on any of these hotspots, they can see the linked content, or portions of it, in the tool tip itself.
If you are linking an hotspot to a YouTube video or an MP3 song, visitors can enjoy the media on the image itself without leaving your page. If the link is pointing to a Wikipedia page, they get to read an excerpt of the page inside the tooltip. If it's a book on Amazon, the thumbnail and price would display in the preview.
There are other interesting uses as well. For instance, you can create an annotated illustration /diagram and users can learn in detail about the different parts of the image by simply hovering the mouse. If you are sharing a route map, you can use these interactive hotspots to explain the route in detail with text and rich-media tooltips.

Tools for Taking Wikipedia Offline

The Best Tools for Taking Wikipedia Offline

Would you like to download the entire Wikipedia on your computer or mobile phone for offline reading? Well, here are some good options to consider.

Download Wikipedia Articles for Offline Reading

Wikipedia, the globe's greatest knowledge compilation book, offers downloadable duplicates (or database dumps) of all its wikis that one could probably download and subsequently access the whole Wikipedia substance on workstations that are not joined to the Internet.
The database dumps are frequently updated and include every single article that's available on the main Wikipedia website. The dumps are available as .xml.bz2 files that you can easily open on your computer using the free and portable WikiTaxi software.
WikiTaxi sends with a shipper that will first uncompress the Wikipedia database documents (.bz2) then after that proselytes them into a .taxi record arrange. Now you open these .taxi records inside WikiTaxi much the same as the way you open .doc indexes inside Microsoft Word and, in the event that you are running easy on space, the initial Wikipedia dumps might be assuredly tossed.
A good alternative to WikiTaxi is Kiwix – this is also free software and available for Mac, Windows and Linux systems. You first install the Kiwix software on your computer and then download one of the Wikipedia editions – the articles are packaged as .zim files that'll open directly inside Kiwix without requiring any conversion.
Kiwix is definitely easier to use than WikiTaxi and that packaged .zim files can read across all popular platforms but the downside is that, unlike the database dumps used by WikiTaxi, the .zim files aren't very frequently updated. Also, the zim package for English Wikipedia doesn't include every article though the packages for other languages are complete.
In the event that you possess an iOS unit – similar to the iPhone, iPad or iPad Touch – you might get the great Wiki Offline application and convey every last trace of the Wikipedia pieces in your pocket. The application renders Wikipedia sections in a lovely interface and backs tabbed scanning so you could probably open various sections side by side. Wiki Offline is likewise ready in the Mac App Store for your Mac OS X.
The alternate alternative for utilizing Wikipedia disconnected from the net is WikiReader – this is a 3.5" monochrome gadget with a capacitive touch screen and holds over 3 million Wikipedia pieces. The redesigns to Wikipedia sections are discharged each quarter – you are able to redesign the apparatus by interfacing it to your machine – or you pick to get overhauls on SD cards.
The WikiReader device costs  $99 and though I haven't tried it myself, it did get a huge thumbs-up from Ars Technica. You definitely don't need this if you carry a smart phone that is always connected to the Internet but could be a good reference tool for the rest of us with an impressive battery life – much like the Kindle.
Finally, if all you want to do is download a handful of Wikipedia articles for offline reading, use the built-in book creator that turns multiple pages from Wikipedia into a PDF book.

A Look at Chromebook After Release: What Real Users are Saying

They are mist-registering based machines, and have taken an absolutely unexpected heading to supply mist figuring, when contrasted and the heading that the brand new Windows 8 managing framework vows. Google suddenly discharged the Chromebook in May 2011, and there was a ton of clamor regarding this late thought in private registering. The Chromebook is the first fully fog working framework. It is the first time we have perceived mist processing in this way. Chromebooks run on the Chrome OS, which is basically an augmented form of the Chrome program. In otherwords, your Chromebook, which looks similar to a laptop will ought to be within the web based world every last trace of the chance to do anything. You could probably consider it as a web browser that has every last trace of the projects and all items else on your machine, aside from, nothing is in reality on your PC. Every little item is archived in your Google record or different within the web based world areas. Windows 8 is taking a fully better go at, it is in addition going fog by permitting the same registering dialect of the web deal with your managing framework freely of your program, and still permitting more universal customizing dialects of requisitions capacity at the same time. With Windows, we get mist and not mist, at the same time. Thus, while just good to go in the US, what have we perceived so far with Chromebooks in a few shortmonths. Still More Tablet Like.Real user reviews are showing us that the Chromebook is more like owning a tablet with a keyboard. This means that we cannot really use one for getting all those tough jobs done, like doing design, producing super-cool presentations or maintaining a company network, for example. In other words, at this stage, the Chromebook is for of a casual internet surfer's mini-computer and can supply the needs of a student who needs to get some research and textual work done. That is not to say that we cannot do more than that, but the fact remains, the Chromebook is not for the mobile warrior. Cheap or Expensive.Google is shipping Chromebooks with payment plans that seem very attractive. Business can have them for about 30 dollars a month over 3 years, and students can get them for about 20 dollars a month for the same period of time. This includes all hardware and software updates. In reality, there will be no hardware updates, and software updates do not exist because there is nothing on the machine to be updated. When Chrome OS or applications are updated, they will not be on your computer anyway. While the price seems very cheap, considering what we are getting for our money, we could be buying a cheaper tablet for much less money. Only if Chrome OS and the applications improve greatly in a very short period of time, will we be getting the amazing deal it sounds like. Remember, the Chromebook is still not a replacement of a personal computer and running something like the new Windows 8 upgrade with improved features. As a matter of fact, it is nothing like a personal computer yet. It is like an oversized smartphone with a keyboard. Other operating system upgrades are usually very cheap, and updates and application updates, such as the Windows 8 upgrade, are cheap or already included in the original price. Internet Relative.Google Apps are numerous and if you are used to using the Google system of getting things done like using Gmail, Docs, and all that comes with it, you are probably used to Google Apps. There are applications to allow you to edit photos and movies, for example. At the same time, if your internet connection is not superfast, using these online applications can be a little frustrating for even novice users. Chromebooks come with 100G of online access per month, and this could easily be used up by someone, if they were a heavy user. 3g users know that some applications do not work as well as with other types of applications. VOIP calling applications still do not have the quality over 3g wireless networks like they do with land-based broadband and cable networks. If you think a Chromebook is a personal computer, as it stands, you are mistaken. It would be great to see the Chromebook provide the same user experience and features of a personal computer, and this is also further dependent on the speed and stability of wireless networks. It is doubtful wireless 3g or 4g networks will improve to match cable stability and speed for some time to come, if ever.

The Customers Guide To Buying A New Computer

Buying a new computer today depends on a lot of things. But the overriding factor, perhaps, is budget. Recent technology advances have brought down the prices for most of the computer's internal components, and there is no good reason why one shouldn’t have a capable machine for under or around $500. This is good news for those brought to bear under the current economic malaise. Do Check: Why Buying A Cheaper Computer May Be A False Economy What the computer is to be used for is another important factor. Most people would want a computer for basic Web surfing, handling email, doing homework, record keeping and the such. Others would want a machine that could carry the heft of the multimedia possibilities, playing games, editing photos or video, downloading and burning music and movies. A little technical stuff will help the buyer in a good way. This article will explain components making up a basic computer model that could be had for around $500. The computer's main component is the CPU (central processing unit) chip. Today’s basic computer would have a CPU made by standard bearer Intel, or its sister AMD. Two-core or quad-core means the CPU acts as ’2 CPUs’ or ’4 CPUs’ at one time. This is good for the multitasking involved in games and video, and other heavy processing tasks. The CPU processes billions of bytes of data, gigabytes (GB), per second. ‘Hz’ stands for ‘hertz’, one processing cycle. An average, good performing computer would have a processing speed around 2-GHz, or less. The other important component is memory. There are two kinds, RAM memory and the hard drive. While it is working, the CPU stores everything temporarily in RAM. Today’s RAM typically comes in the form of DDR-2 chips, ‘DDR’ standing for ‘double data rate.’ Using RAM sticks with 1 GB storage capability, and depending on the computer’s operating system, the basic computer will have one or two sticks of 1 GB RAM. Optimal operating systems, such as Windows Vista, or Windows 7, require 2 to 4 GB. The more RAM the computer has, the better runs the CPU. Data is permanently stored on the computer’s hard drive. Technology on hard drives has improved explosively. Storage space has become cheap, with 250 GB, 500 GB, and terabyte (1,000 GB) drives becoming common. The budget machine would easily have around a 500 GB hard drive. These components make up the basic computer. Adding to them the mouse, keyboard, and monitor results in the basic 'desktop.' Several other accessories are standard with this model. They include a DVD-RW drive for reading and writing CDs and DVDs, USB ports for hooking up USB components, and a modem for internet connectivity. All this can be had for, around, $500, and enhanced for a few hundred more. Today's trend, influenced by the tablature design, is to pack the components into one unit with the monitor, the all-in-one model. The jury is still out on this phenomenon, but it certainly bears watching. The desktop model enables easy, accessible care and repair, and pretty good affordability. Dell Inspiron 15R 1570MRB 15.6-Inch Laptop (Mars Black) will be the perfect fit for those who are looking to buy computer within the $500 price mark. Looking for computer stores Perth?

Asus GTX 550 Ti DirectCU – An Ideal GPU For Low Budget Gaming PCs

After the GTX 560 Ti, we now have an even more affordable GPU from Nvidia, the Asus GTX 550 Ti DirectCU, which is targeted at budget gaming PCs. It features the new GF116 GPU, which benefits from transistor level improvements like the GTX 580 and GTX 560 Ti. This means less heat and more performance per watt thanks to higher memory bus width and clock speed. The 550 Ti has 192 shader units, which is similar to the GTS 450. However, the memory bus is wider (192-bit versus 128-bit on the GTS 450) and both the core and memory are clocked around 100 MHz higher at 900 MHz and 1025 MHz respectively. Factory-overclocked variants of GTX 550 Ti graphics cards by a few brands are already available. The Asus GTX 550 Ti DirectCU features their new cooler, which is seen on most of their new cards. The GPU on this card is overclocked by a mere 10 MHz and the memory speed is untouched. The Zotac GTX 550 Ti Amp Edition is factory overclocked to quite an extent. The core speed is cranked by 100 MHz and the memory speed by 75 MHz. The video outputs on both the cards are also different. Zotac offers DisplayPort, HDMI, and a pair of DVI ports, while Asus off ers a D-sub and an HDMI port. Performance-wise, the GTX 550 Ti fits right between the GTS 450 and GTX 460. The overall 3DMark Vantage score was 10050 at stock speed. Crysis Warhead at 1920×1080 in Gamer mode ran at 34 fps. Mafi a II was also smooth at 32 fps, but with PhysX disabled. The GTX 460 was faster by 5 to 8 fps and the Radeon HD 5770 came close, but took a hit when it came to tessellation and PhysX. If your budget for a gaming PC is up to Rs 45,000, this GPU would be ideal. Specification of Asus GTX 550 Ti DirectCU: GPU: GTX 550 Ti Memory: 1 GB GDDR5 Memory bus width: 192-bit Speed (Core | Memory): 900 MHz | 1250 \MHz Stream processors: 1408 Video outputs: Dual-link DVI, HDMI and mini-DP The Asus GTX 550 Ti DirectCU is a Graphics Card which is Good Value for Money because its Priced at Rs. 9,600/-.

Informatics students discover, alert Facebook to threat allowing access to private data, bogus messaging

A Facebook security vulnerability discovered by a pair of doctoral students at Indiana University Bloomington's School of Informatics and Computing that allowed malicious websites to uncover a visitor's real name, access their private data and post bogus content on their behalf has been repaired, Facebook has confirmed.
The vulnerability discovered by Rui Wang and Zhou Li enabled malicious websites to impersonate legitimate websites, and then obtain the same data access permissions on Facebook that those legitimate websites had received.
Wang and Li said the vulnerability occurred when a user informed Facebook of his or her willingness to share information with popular websites like ESPN.com or YouTube. Whenever a website makes such a request to Facebook via the user's browser, Facebook passes a secret random string called an authentication token back to the requestor for identification. Whoever holds that authentication token can convince Facebook that they are, say, ESPN.com and then gain unfettered access to the shared data.
Facebook confirmed the discovery and in a statement said the problem was repaired and that the belief was that no sites had been compromised.
"Researchers at Indiana University reported a vulnerability in our Platform code to us, and we worked quickly with them to resolve it. It was fixed shortly after it was reported. We're not aware of any cases in which it was used maliciously," the statement said. "We thank the researchers at Indiana University for bringing this to our attention, and for demonstrating the value of responsible disclosure."
The researchers identified a flaw in the way the token was transmitted using two Flash objects: one inside Facebook's iframe passes the token to the second, which in this case would be embedded at ESPN.com. The transfer mode can be selected through "transport='flash'" with the security guarantee being that both flash objects are supposed to come from the same domain (i.e., Facebook) before they can talk.
The researchers found, however, that such a same-domain assumption is not always valid because Adobe Flash allows cross-domain communication with an unpredictable domain name that is prepended by an underscore symbol in the connection name. This allows an attacker website to steal an authentication token by choosing the transport='flash,' replacing the receiver flash with its own and then initiating a cross-domain communication with the flash inside the Facebook-controlled iframe to get the token and send it to the attacker's flash.
"This vulnerability has several implications," Wang said. "Basically, any user with a valid Facebook session loses anonymity and privacy to any website, even one with embarrassing or sensitive content."
Facebook allows some websites like bing.com to directly access a user's public data without explicit consent. This enables the malicious website impersonating that site to do the same. Moreover, if the user has ever granted any website, such as The New York Times, YouTube, Farmville or ESPN, the permission to connect to their Facebook account, further damage can be inflicted, including disclosure of private data that the user does not want to share with others, and impersonation of the user to post bogus news or comments on friends' walls. This form of propagation resembles the famous MySpace worm released in 2005, they said.
"Our attack utilized a feature of Adobe Flash called unpredictable communication, and an important distinction between an unpredictable communication and a normal communication is that the former is done through a connection where the name starts with an underscore symbol," Li said. "Therefore, Facebook could check for this symbol to determine if a potentially malicious website tries to do unpredictable communication."
And that is exactly what Facebook started to do once they were alerted to the problem by Wang and Li, who were working under the supervision of School of Informatics and Computing Associate Professor XiaoFeng Wang and Shuo Chen, a researcher in Microsoft Research's Internet Services Research Center.
XiaoFeng Wang, the students' adviser, said Facebook relies on same-domain communications that allow websites to specify Adobe Flash as the communication mechanism.
"In a normal situation, two flash objects can only do same-domain communications, and, in fact, security of Facebook's authentication crucially depends on same-domain restrictions," he explained. "However, Facebook allowed the Adobe Flash communication mechanism but did not disallow the unpredictable domain names. This is how a malicious website could establish a channel to enable two flash objects in different domains to communicate."
To portray the seriousness of the vulnerability, the team made a video demo that can be viewed here.
Facebook officials noted that a contact form at both the Facebook Help Center and from the "Whitehats" tab on the Facebook Security Page are available in the rare instances in which vulnerabilities are found.
"We also recently rewrote our responsible disclosure policy to make it even easier for researchers to let us know when they find a vulnerability, so we can fix it quickly and before it's exploited. Our new policy was praised by the Electronic Frontier Foundation in a recent blog post here," the statement said.
