Want to know how your blog is doing on social sites like Twitter, Google+ and Facebook?

The updated Social Sharing Analytics tool helps you quickly measure your blog’s (or anyone else’s) performance on popular social sites including Twitter, Facebook and Google Plus. Just paste the URL of any website that has feeds and you are good to go. The tool extracts all the recently published stories from the RSS feed and displays the corresponding social counts.

Now we also have a WordPress plugin that displays the social sharing counts of all your blog posts right inside the WordPress Admin dashboard.

As you can see in above screenshot, the plugin adds a new “Social” column to your “Edit Posts” screen in WordPress where the respective sharing counts (likes, tweets and +1s) of all the blog posts are displayed.

The plugin makes no changes to your WordPress blog posts or database. For best performance, set WordPress to display 10 or 20 posts in the Edit screen

Secure your Dropbox Account with 2-Step Verification

Learn how to secure your Dropbox account with two-step verification using your mobile phone and stay safe even if your Dropbox password gets leaked.

Something everyone has been eagerly waiting for. You can now secure your Dropbox account using 2-step verification meaning an intruder would need more than just your password to access any of the confidential files stored in your Dropbox folders.

Enable 2-step verification to secure your Dropbox Account

The 2-Step verification system of Dropbox is pretty similar to that of Google.

You can either choose to receive the 6-digit security codes on your mobile phone via text messages (Dropbox supports international phone numbers too) or if you have a smartphone (Android, BlackBerry, iOS or Windows Phone), you can download the Authenticator app and generate time-sensitive codes locally on the phone itself.

To get started, go to your Dropbox account’s security page and Enable two-step verification – the setting is available right at the bottom of the page. Now follow the wizard to associate your phone (or phone number) with the security option. Dropbox will also provide an emergency backup code that you should print and keep at a secure place – this will be required if you ever lose your mobile phone and need to get into Dropbox sidestepping the security settings.

Once 2-step authentication is enabled, go to dropbox.com and download the latest installers for Dropbox (available for Windows, Mac and Linux). There aren’t any new features here except that these new software builds include support for signing-in through 2-step verification.

Also, if you have setup Dropbox on your mobile phones and tablets, it maybe a good idea to unlink all these devices from your Dropbox account and relink – all these device will now require a 6-digit code that is only available on your mobile phone. And whenever a new computer, phone or tablet is used to log into your Dropbox account, you also get an instant email notification.

Safely keep your emergency Dropbox Code because you never know when you may need it.

Thank you Harmeet Singh for the tip.

Microsoft’s New Logo Recreated in CSS

Microsoft recently unveiled a new corporate logo where four colored squares represent Windows, Office, Xbox and Windows Phone family of products.

The PDF document suggests that designers used Adobe Illustrator CS5 to create the original logo but @mohamedmansour shows us how to recreate the same logo using few lines of HTML and CSS3.

If the live demo doesn’t look right in your screen, the Segoe font is probably missing on your computer though some have suggested replacing Segoe with Open Sans, a Google Font.

Here’s the full code courtesy Mansour.

Introducing Secure Passwords

Download Password Manager RoboForm.com/Password-Management
Never Forget Your Passwords Again. Over 50 Million Downloads To Date!

You want to create lengthy, complicated and unique passwords for every website that you use but that rarely happens in practice because complex passwords are impossible for anyone to remember.

Some people rely on password management software like LastPass or KeePass that store all your passwords in an encrypted database which is then protected by a single master password. You enter the master password and you instantly have access to all your stored user logins and passwords.

Set unique passwords for all your web accounts but remember just one pass phrase

A Unique Password for Every Website

Here’s an alternate solution that I initially created for internal use. The tool is called Secure Passwords and it generate unique and strong passwords for your various web accounts using using the secure bcrypt algorithm.

The advantages are that your passwords aren’t stored anywhere, the passwords are hashed using bcrypt (irreversible) and all you have to do is remember is one master pass phrase. The password generator works on both desktop and mobile screens. You can also download the tool from Github as a ZIP file and run it offline on a USB drive or upload it to Dropbox.

To get started, enter your user name (or login id), the site’s domain name (e.g. google or facebook), your master password and hit the generate button. The tool will instantly create a unique password based on your input and it will always generate the same password for that set of parameters.

How Secure are my Passwords?

The passwords are impossible to guess as they are made of digits, special characters and letters in mixed-case. The passwords are generated using bcrypt which is still resistant to brute-force attacks and therefore it will be impossible for anyone to decrypt the master pass phrase should any of password ever gets leaked online.

Also, the tool computes passwords in your web browser itself and not a single byte of data is transmitted elsewhere. You can browse the full source code at Github.com and, if you know a bit of programming, modify the code even further to suit your requirements.

Here’s another password trick suggested by Mozilla that recommends picking a base password and then adding a different suffix and prefix based on the website.
