Did you know, you can not only upload video files to SkyDrive and Google Drive but also play them online. Although it is possible to upload video files of any format, SkyDrive can play H.264 (.mp4) and Windows Media Video (.wmv files) videos through a Silverlight player . Google Drive lets you upload and play the following video formats : WebM files (Vp8 video codec and Vorbis Audio codec) .MPEG4, 3GPP and MOV files - (h264 and mpeg4 video codecs and AAC audio codec) .AVI (many cameras use this format - typically the video codec is MJPEG and audio is PCM) .MPEGPS (MPEG2 video codec and MP2 audio) .WMV .FLV (Adobe - FLV1 video codec, MP3 audio) It provides a YouTube-like interface & also lets you add caption tracks to your video files.

There have been times when I wanted to just copy the URL of a site mentioned in a Google search result without having to go to the website & then copying it from the address bar. However when I right click & copy the URL, this is how the address typically looks - http://www.google.com/url?sa=t&rct=j&q=menu_elements_selector &source=web&cd=5 &cad=rja&ved=0CEIQFjAE &url=http%3A%2F%2Fapi.jquery.com%2Fattribute-ends-with-selector%2F &ei=LdQ8UKOkJYPTrQfn0IHIDA &usg=AFQjCNFmICOvDtxuImTTeXY3pCDQNW6yVQ (URL broken with new lines for readability & to preserve formatting) Digging into the source code reveals that there is a mousedown event that fires up when the link is accessed & re-creates the HREF of that anchor tag so that you have to pass through a quick additional Google step before you can reach the search result site I wished there was a bookmarklet that could stop Google from mangling the URL and skip the redirection...

It is how you can promote your site for free. This image from SEO expert Rand Fishkin's article sums it up well -

Although Internet Explorer 10 is the last among popular browsers to implement spell-checking, it is the first to support auto-correction. Did you know, IE was the first to implement CSS (in IE 3) and the idea of AJAX besides a lot of contributions to HTML5 Some interesting facts on this feature from the IE blog - Preexisting text will not be spellchecked, however pasted text will be checked when it is inserted. Spellchecking is active by default on <textarea> and contenteditable elements, and off by default for text boxes Web developers can override the defaults using the spellcheck attribute - spellcheck=true (enabled)  In the rare case that auto-correct changes something that you didn’t want changed, you can undo the change via CTRL+Z (Undo) using the keyboard, or bring up the auto-correction context menu using the mouse. In addition to using the mouse, the auto-correction menu can be activated via the keyboard by moving the insertion point inside of the word and ...

I recently had to explain to a senior citizen, an Internet newbie, on the phone how to upload files onto Google Docs/Drive. It then stuck me as odd that the Upload button next to the Create button doesn't have a label on it but rather a stupid icon. I was suprised about how a company that supposedly spends a lot of time on usability testing and picking the right shades of color  could not have kept things simple and intuitive by giving a button a label like it's normally done. Let's say you accidentally closed the Tasks window in Gmail. How do you get it back? Its under the dropdown-kind-of-thing that you get when you click on the little arrow next to the Gmail "label" to be continued...

This tip applies to Internet Explorer and Firefox. Picture this - While searching for something on the Web, you have opened a dozen tabs and for some reason you have to turn off your PC/laptop quickly. How do you save  all the addresses in tabs within a window for reviewing later? Madhivanan has a simple solution - Go to Tools > Internet options In the General tab, click the Use current button in the Home page  section. It will display all URLs in the textarea above it. Copy & paste it in some document for later use. The actual purpose of the Use current button is to set URLs so that the related pages open automatically when IE is opened. This tip can be extended to Firefox as well - Go to Tools > Options In the General tab look for the Use Current Pages button in the Startup section. When you click on the Use Current Pages button, all the URLs of the pages open in different tabs are copied to the Home Page text box with a pipe delimiter. C...

InformIt has got authors (Erik M. Buck, Obie Fernandez, Danny Kalev, Eric Lippert, Rob Pike, Mark Summerfield, Bill Wagner) of some popular programming books to share the best programming advice they have ever received . Here it is paraphrased in brief - Write less code.  Take a moment to understand the error message at the top of an exception/stack trace before making additional changes to your code. ..language changes and skill improvements — require constant reading.  ..be part of a team that values progress over politics, ideas over territory, and initiative over decorum.  ..thinking before debugging is extremely important. If you dive into the bug, you tend to fix the local issue in the code, but if you think about the bug first, how the bug came to be, you often find and correct a higher-level problem in the code that will improve the design and prevent further bugs.  TDD & refactoring   Make code usable before you make it reusable.

The demand for printed books is falling because of the Internet and digital alternatives. Encyclopaedia Britanica which was first published in 1768 will stop publishing their print edition from this year . In case of rapidly changing subjects like technology, printed books can't keep pace with online content as it can be updated easily and frequently. Moreover, having rich media in online content makes it more appealing than books. It is now possible to have the best of both worlds. Authors & publishers can choose to place mobile barcodes like QR Codes or MS Tags in the printed material on topics that can change, to connect readers to updated material on the book's website. This can improve the longetivity of a book. QR Codes and MS Tags need a smartphone app to enable the redirection from the print medium to a web page. The URLs thus exposed through printed tags can be tracked. Lee Lefever's upcoming book 'The Art of Explanation' will have 16 QR codes...

Search engines rely on bots to index web pages but did you know Wikipedia uses more than 700 active bots to keep its content clean! Wikipedia which is 50 times larger than the Encyclopaedia Britannica currently has 4,005,000 articles in the English edition and 22.8m articles in 285 language editions. The bots delete vandalism and foul language, organise and catalogue entries, and handle the reams of behind-the-scenes work that keep the encyclopaedia running smoothly and efficiently.  BBC News Magazine has a neat writeup on what these bots do - "Interwiki" bots link articles on the same subject in different languages Flag potential copyright violations and other irregularities for human review Add dates to "cleanup" tags so human editors know what needs attention Add articles to category lists, and lists of categories to articles Format and repair citations and references Compare ISBN numbers Flag images that need more licensing details Behind the scen...

Once you install Skype, it will load on startup everytime. If you're low on memory, this will mean an extra app hogging resources even though you may not need it every time. I found it annoying that the option to disable auto-startup doesn't appear until you sign in. It's only after you log in that you see the checkbox option Start Skype when I start Windows checked by default (look under Tools | Options | General Settings). Uncheck this option to prevent Skype from auto-starting after Windows boots up. Also see: HOW TO speed up your PC

To download a document from a Library in SharePoint 2010, you can right click on it, select Send To & choose Download a Copy - But what if there were several documents and you wanted them all at once without going through the hassle of downloading each one of them individually? Jump to the Library tab & click on the Open with Explorer option - This will open up your Windows Explorer with the folder containing the documents you require within them. Thanks Lakshmikanth for the tip.

Microsoft's Channel9 website has published a two-part video series with 42 episodes on HTML5, CSS3 and JavaScript by a great tutor. The course is delivered by Bob Tabor who runs LearnVisualStudio.net, a video tutorial site. In the first episode  in the HTML5 & CSS3 series, Bob clearly outlines what it will NOT cover and sets the right expectations. The videos can be downloaded (recommended) or viewed online on a Silverlight-supported browser. I was pleasantly suprised to see that some of the online videos on Channel9 now let you jump to a specific point in the video without having to start from the beginning in case you've already watched a portion of a long video earlier. Unlike earlier, the duration of the video & the file sizes of the video in the multiple formats that it is available for download, are also shown. If you're on a lean-bandwidth connection, you can try downloading the video in the format that has the smallest size (however on download...
