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.
