Following a recent announcement , folks with a MSDN Subscription can get enhanced Azure benefits. However, the catch is that those Windows Azure MSDN benefits are intended for development and test purposes only. Usage within that Windows Azure MSDN subscription does not carry a financially-backed SLA. However, if you want to continue using the older MSDN benefits subscription (which has less features and a higher per-compute rate - but does support production usage) you can go to your accounts page and opt-out of the new MSDN plan.  That will allow you to continue using your existing benefits for another 12 months. But where is the "accounts page"? Either use this direct link to the Account page or click on your account name that's on the top right after you login to the Azure portal . Select View my Bill from the menu that slides down to be redirected to your Account page You can then opt to have your subscription transition to the new MSDN benefit immediately o...

My Wife and I share a love for good, healthy food and cooking. We analyze (mostly vegetarian) recipes we find online, on TV or in print. Not only that, we occasionally hang out in the Seasoned Advice forum , a Q & A discussion board in the StackExchange family, to learn about what people around the world are cooking. This kind of fascination for cooking, made us jump at the idea of reviewing " Cooking for Geeks " when I spotted it in the O'Reilly Blogger Review Program's list of books . We enjoyed it during the first reading and will keep going back to it. The author Jeff Potter's mixes science and cooking to dish out an educational and entertaining book that helps you "understand cooking". Cooking for Geeks  has numerous tips, food science facts, recipes and interviews with cooking experts and aficionados, all mashed-up into 7 chapters that will keep you engaged all through out. Among the passionate people he has interviewed are Maureen Evans (T...

This Week I Learned: .. a Ph.D. student named Thomas Knoll started working on a revolutionary program for making images. Photoshop, as it was eventually named, turns 25 this year, and has been so successful that it has made the rare transition from brand name to verb . BSNL, the Indian Government-run telecommunication company, has discontinued the 160-year-old telegraph service. Telegrams encouraged concision. British General Sir Charles Napier is said to have sent home a one word telegram, "Peccavi", Latin for "I have sinned" after claiming Sind.

The total amount involved in frauds relating to credit card, debit  card and internet banking rose 74% to Rs 38.4 crore in 2012 - Indi...

Books in the PacktPub Instant series aim to provide "short, fast, focused guide delivering immediate results". I found the last two jQuery-related "Instant" books I read very useful as they covered the essentials in less than 50 pages. When I received a review copy of the book Instant jQuery UI Starter by Jesse Boyer , I expected it to be in the same league as the earlier books but it fell short. jQuery UI , built on top of the jQuery JavaScript Library, simplifies the life of web developers. The elements of the jQuery UI Library are divided into four sections - Interactions, Utilities, Widgets, Effects. This book provides a casual introduction to jQuery UI which is a vast, continuously evolving topic. Unlike the other two "Instant" mini-books, I found the content of this to be fluffy and too verbose. Call it nit-picking but the author's choice of words was a little odd at some places ("Let's unpackage the file","unminifie...

A SPA is a web app contained in a single page – where ‘pages’ are nothing but DIVs being shown/hidden based on the state of the app and user navigation . Single Page Applications heavily use client side scripting to provide rich functionality to the end user. Gmail is probably the first well known SPA implementation which has been around since 2004. ASP.NET MVC 4 provides a basic framework for building SPA applications. Pros: The big reasons to do SPA are the 3 R's: Reach, Responsive UX and Reducing roundtrip postbacks. Cons: Navigation – SPA’s by nature break the normal navigation mechanism of the browser. Normally, you click a link, it launches off a request and would update the url on the address bar. The response is then fetched and painted. In an SPA however, a link click is trapped in JS and the state is changed and you show a different div (with a background AJAX request being launched). This breaks Back/Forward navigation and since the URL doesn’t change,...

1. No date of publication/update - I often land up in MSDN via search engines. There have been countless times when I've read half-way through a piece of documentation and then found the article to be obsolete or referring to an older version. In recent years, MSDN does have a drop-down to switch between versions of the product documentation but this is not consistent across its range of products. Does it hurt to have a date of publication/update? 2. Lacks images & illustrations - Realizing the importance of illustrations in quality content, Philip Greenspun, a teacher at MIT, donated $20,000 specifically to fund the creation and improvement of illustrations for Wikimedia . He wrote, “It occurred to me that when the dust settled on the Wikipedia versus Britannica question, the likely conclusion would be ‘Wikipedia is more up to date; Britannica has better illustrations.’” . There are numerous places in MSDN, where I wished there were illustrations to go with the explanation...

This Week I Learned: Google has killed Quick View & Instant Preview features in Search. Instant Previews are page snapshots that allow users to get a glimpse of the layout of the web pages behind each search result, in order to help them decide whether or not to click a link. Low usage has been suggested as the reason for abandoning Instant Preview . Some detractors complain the low usage may have been because the button was almost hidden. Foursquare founders, Naveen Selvadurai and Dennis Crowley always tried to pitch Foursquare less as a check-in app and more as a “a data-driven recommendations engine which analyzes and rewards real-world behavior.” ..articles that get a lot of tweets don’t necessarily get read very deeply. Articles that get read deeply aren’t necessarily generating a lot of tweets.    A 20-year-old Indian student from Cornell broke into the  Indian Certificate of Secondary Education (ICSE)  database so that his friends could know their re...

A proponent of the Quantified Self movement and the co-founder of Foursquare, Naveen Selvadurai, has published a " personal API " consisting of his day-to-day personal details (related to his sleep, weight, steps, fuel/activity and checkins) as a step towards building self-awareness software. He calls it api.naveen . The data therein has been normalized from various sources: manual capture, nike fuelband, jawbone up, withings, fitbit, foursquare and various apps . Image from the Human API website The Quantified Self movement is based on the premise that by measuring and analyzing behavior, one can improve it . You’re less likely to splurge on french fries, say, if life is a game of improving your fitness and all the apps on your homescreen are keeping score . This GigaOm article informs that there are projects like the Human API ("all human data streams in one open API") which help people find value in their personal data.

This Week I Learned: JSDelivr is a CDN for developers and webmasters that hosts JavaScript libraries, jQuery plugins, fonts, CSS frameworks. JSter maintains a catalog of (over 1153) JavaScript libraries and tools for web development. Microsoft is the first multinational company to make public cloud services available in China. Opera 15 will use Blink rendering engine and V8 JavaScript engine. One of the reasons for the delayed capture of the Boston Marathon bombers was that the databases contained a misspelling of the suspect’s name — “Tsarnayev” instead of Tsarnaev — and two incorrect dates of birth. Wall Street Journal columnist, Walt Mossberg is considered the most influential technology critic in the world.
