"Smart" phone & portable device features of 2012

Posted on 19:39 by Unknown


Pogie awards celebrate the best ideas of the year: ingenious features that somehow made it past the lawyers, through the penny-pinching committees and into real-world tech gadgets — even if the products overall are turkeys. Here's a paraphrased summary of the winning ideas:

  • Power Nap is a feature of OS X Mountain Lion that works on recent MacBook models. It lets the laptop keep backing itself up, downloading e-mail and syncing its online data (calendars, calendar notes, reminders, photos) & allows the network activity to chug away even when the lid is closed.
  • In Windows Phone 8, Kid’s Corner is a sanitized version of the operating system that contains only apps, music and videos that you’ve handpicked in advance. With this feature web browsing, e-mail, phone calls  and in-app purchases can be made off limits for kids and it can be activated with a quick left swipe from the Lock screen
  • The Ciago iAlert and Cobra Tag are Bluetooth keychain fobs that communicate with your iPhone or Android phone. Once you’re 30 feet away from the phone, the keychain starts beeping, as though to say, “You’re leaving your $200 phone behind, you idiot!” These electronic leashes works the other way, too; the phone beeps if you leave your keys behind.
  • Bluetooth 4.0, built into the latest iPhone and Android phones, is also called Bluetooth LE (low energy) for a reason. For the most part, it uses power only when it has data to exchange. 
  • Recent models of models like Atrix, Droid Razr have a feature that automatically turns your phone to Vibrate during the hours of any meeting on your calendar. If you have a Moto headset or car dock, your phone auto-detects when you’re driving. At that point, the phone sets the ringer to Loud, turns on GPS, announces incoming callers’ names by voice, and auto-responds to incoming text messages with an “I’m driving — call you later” response when it is in Driving Mode.
  • In the Do Not Disturb mode in iOS6, your phone doesn’t ring, vibrate or light up. It’s just like Airplane Mode, except that you can designate certain people whose calls and texts are allowed to ring through. A special checkbox, Repeated Calls, handles urgent situations. If anyone tries to call more than once within three minutes, they’re obviously desperate to reach you. Do Not Disturb will permit those calls to ring.

5 reasons to try Vocabulary.com

Posted on 09:43 by Unknown

  • Vocabulary.com does a great job of "gamify-ing" the process of building your vocabulary through its adaptive learning system
  • It is among the PC Magazine's Top 100 Websites & the Time magazine's top 50 websites of 2012 
  • The site's main attraction, the quiz, has some 100,000+ questions and the answers are educative. The site reportedly contains over 100 million sentence examples.
  • The site is ad free
  • Their dictionary is blazing fast. In an unscientific comparison, it seemed to beat another contender, thefreedictionary.com with the print layout, for the title of world's fastest, smartest dictionary. 
While there is no mention on the current version of the website about who created it and when, going by the records on Archive.org it appears to have started in 1998 by the husband-wife team of Jan and Carey Cook. The gamification of the site seems to have been done around the April 2011 period.

I learnt about the site from the English.SE Q & A website and I'm hooked. I have a few nits to pick though.

The way the scoreboard sticks to the quiz section, it seems there is something hidden below the quiz box. A small left margin for the scoreboard would make it a less distracting for me. 

A keyboard shortcut to move to the next question would be nice.

Google is "in the business of knowledge" - Sundar Pichai

Posted on 21:16 by Unknown


From his interview in the Economic Times -

"We, as Google, are not in the search business. We are in the business of knowledge." - Google's Senior Vice President for Chrome and Apps & IIT-ian, Sundar Pichai  (40)

A few facts -


  • About 20% of the queries we get everyday are new.
  • Our user base for Gmail has grown to 50 million users in India. 
  • Chromebook will be available in at least two countries in the Asia Pacific region, excluding India, by March 2013. 


It appears that Sundar Pichai likes taking potshots at Microsoft. Samples -

  • "Windows 8 breaks the backward compatibility of its own end-toend ecosystem."
  • "...we are constantly changing the Gmail code. It is like refuelling a plane in mid air. It happens on a day-to-day basis. If you compare it with Windows, one gets to see only four versions of Windows in five years."
  • 'IE 10 makes available cloud experience but they (Microsoft) expect you to use Windows."

I passed the 70-480 exam!

Posted on 00:24 by Unknown


Taking advantage of the free Exam Voucher for the Microsoft exam 70-480: Programming in HTML5 with JavaScript and CSS3, I  passed the 70-480 exam yesterday.

I used the following resources for preparing:

  • W3Schools - I've been referring to this awesome tutorial site since a decade and preparing for this exam gave me a chance to dig deeper into the HTML5 & CSS3 sections
  • Microsoft Virtual Academy course Developing in HTML5 with JavaScript and CSS3 Jump Start 
  • Hello! HTML5 & CSS3 by Rob Crowther
  • MSDN Internet Explorer API reference

This exam whetted my appetite for learning HTML5 & the bold new possibilities that it opens up.

Reddit - Vital Stats & Interesting Facts

Posted on 08:45 by Unknown

Vital stats & interesting facts about Reddit paraphrased from this article on Forbes:
  • Reddit was started in 2005 by two fresh University of Virginia graduates, Alexis Ohanian and Steve Huffman (22), after they couldn’t finance a previous brainstorm: An online food-ordering site.
  • Ohanian created a zany aura, doodling up a goofy red-eyed alien named Snoo that became Reddit’s logo.
  • Reddit’s visitor traffic was so feeble at first that the founders spent hours posting content under a variety of fake names.
  • Despite a clunky user interface that has barely been updated since 2005, Reddit attracts 3.4 billion page views a month, putting it among the 70 most visited sites in the US.
  • Reddit spends just $7 million a year to support a 22-person payroll and 75 servers rented from Amazon’s cloud.
  • Most of the content on offensive subreddits is posted pseudonymously and lives on the outer edges of what’s tolerable under the First Amendment.
  • Exact terms haven’t ever been disclosed, but insiders say Reddit was bought by Advance Publications' Condé Nast magazine division for $5 million or less in 2006. 
  • Since Condé Nast stepped in, Reddit’s user base has grown about 80-fold.
  • Reddit’s Ask Me Anything (AMA) crowdsourced interview series is now an important stop on the publicity tour for movie actors, directors and authors. 
  • Reddit jargon:
    • ELI5  - Explain like I'm Five
    • IRL   - In Real Life
    • NSFW  - Not Safe For work
    • TIL   - Today I Learned
    • TL;DR - Too Long; Didn't Read
    • Karma - A tally of how many people like your posts or comments
    • Rage Comics - Awkwardly drawn, four-panel comics in which characters get angry about their relatives, their computers or anything.

What's common to Lucene & Hadoop

Posted on 12:39 by Unknown

Lucene & Hadoop are both created by Doug Cutting and they are open-source.

Lucene is a text search engine API. It can be used by applications which requires full text indexing and searching capability. Lucene.Net is a port of Java Lucene written in C# and targeted at .NET Framework users.

Hadoop is a framework that enables the distributed processing of large data sets across clusters of commodity hardware.

Hadoop is a clone of Google’s MapReduce number-crunching platform.

Hadoop consists of a file system (HDFS) and a number-crunching platform (Hadoop MapReduce). The file system lets you spread data across a cluster of machines, and the MapReduce processes this data by sending little pieces of code to each individual server.

In 1998, Google was the 19th search engine to enter the market. Google’s implementation of MapReduce on GFS and [Google's distributed database] BigTable vaulted them to leadership within two years.

4 practical ways to protect your privacy online

Posted on 23:30 by Unknown

A recent Wall Street Journal article reveals that companies today are increasingly tying people's real-life identities to their online browsing habits.

WSJ also provides these startling privacy insights among others -
  • Americans' license plates are now being tracked not only by the government, but also by repo men who hope to profit from the information.
  • The government follows the movements of thousands of Americans a year by secretly monitoring their cellphone records . 
  • One of the fastest growing online businesses is that of spying on Americans as they browse the Web.
Here are some ways drawn from online resources, to protect your privacy online  -

1. Log Out of Social Networks When Browsing and Clear Cookies

All those little “Like” buttons and other social-networking technologies across the Web can inform the parent company of your browsing habits whenever you encounter them. This is true even if you don’t actually click the button.

Did you notice, many sites these days don't show the log-out option  distinctly. It takes an extra step to locate it.

2. Use Disposable Email Addresses

If you want to sign up for newsletters or for accounts that require an email address, but you don’t want that address to be used to track you, you should consider disposable addresses.

Gmail lets you add a plus sign and a word or phrase to your existing email address. For example, name+site@gmail.com will get forwarded to name@gmail.com, allowing you to use many different “name+” combinations when you sign up for services online. It’s true that it would be easy for a program to identify you by discarding anything after the plus sign, but it’s currently unlikely that most services would expend the effort.

 3. Use a Fake Name

Finally, remember that in many cases, there is no rule that says you need to use your real or full name online. We’re not advocating fraud: People you’re buying something from might need to have your actual information, for example. But think about what you enter into forms online, and if you don’t need to use real personally identifiable information, don’t do it.

It's funny, the lengths we have to go through to protect our privacy. A recent Wired magazine article on passwords recommends giving bogus answers to security questions - not something hackers can get through social-engineering.

4. Activate the "Do Not Track" browser preference

"Do Not Track" is a preference that users can set in web browsers to inform websites that they do not want to be tracked, which may help protect them against forms of tracking on the web.

Enabling ‘Do Not Track’ means that a request will be included with your browsing traffic. Any effect depends on whether a website responds to the request, and how the request is interpreted. For example, some websites may respond to this request by showing you ads that aren't based on other websites you've visited. Many websites will still collect and use your browsing data - for example to improve security, to provide content, services, ads and recommendations on their websites, and to generate reporting statistics.
