Piggy backing on WiFi

It’s always a good idea to secure your wifi network. Don’t leave it as open network. Even if you are running a motel and want to provide free wifi to your guests, protect your business wifi with password and change the password every 2 weeks. If you have set up wifi in your home, protect your network with strong password. If some criminals use your wifi network for illegal activities, you will be accountable. Although you can prove that you are not the culprit but a victim, you need to jump thru lot of hoops to prove your innocence. We…

Google +

Google had an amazing social networking platform – Orkut. It was popular in India and Brazil. However, Google didn’t properly leverage it to compete in social media battleground. I am not sure about Brazil, but Indians ditched Orkut and massively migrated to facebook in the last two years. Google woke up and trying to compete with Facebook with a new product called Google+. The new product is trying to exploit some major weaknesses of Facebook. Privacy features in Facebook is kind of joke. If you set your profile and adjust privacy settings to have your pictures visible only to your…

Yahoo-Mail Vs Gmail

For many years, I have been a big fan of Yahoo email. User interface of Yahoo email was used to be simple. If you are familiar with Microsoft Outlook or Outlook Express, navigating Yahoo email was a piece of cake. Over years, Yahoo email becomes more and more unreliable. Frequently, it fails to load the pages. Email messages die while being sent out to the universe. If you use Yahoo email with firefox 3.x, you would have noticed even more crashes in Yahoo email. On the other hand, Gmail is lot more reliable compared to Yahoo email. The feature I…

Microsoft attack the spammers and pull the plug on spam servers

Microsoft and many security companies like Symantec believed that Rustock “botnet”, computer farm (network of computers), was the main culprit behind 50% of the spam that is hitting your inbox. Today, Microsoft and U.S. marshals seized computer equipment from Internet hosting facilities across the U.S. in a sweeping legal attack designed to cripple the botnet. Microsoft’s digital crimes unit staff accompanied U.S. law enforcement officers in raids conducted at Kansas City, Mo.; Scranton, Pa; Denver; Dallas; Chicago; Seattle and Columbus, Ohio. The idea is to knock out the brain of the network that spans globally. This nasty network was used…
