Turn of displaying Adobe PDF Reader in browser

If you have Adobe Reader 7 or earlier make sure you turn off the option "Display PDF in browser". Follow these three simple steps to turn it off.

  1. Start Adobe Reader
  2. Goto Edit > Preferences  or press Ctrl + "K"
  3. Select Internet in Categories
  4. Make sure that the Display PDF in browser is unchecked.

Make sure you follow these steps as soon as possible or someone could be going through your personal information online. I have developed a proof of concept that can use the flaws in Adobe Reader to get information by only visiting a webpage. But I don't think I will release it online as it makes little sense to release it. It could be used to gain way too much private information from your browser. Make sure you turn it off before you end up loosing a lot of personal information.

I had real expectations from iPhone as a platform but the way its been going so far I would never bother developing for it. Officially there is no SDK with which one can build applications. What ever tools the community had built have been rendered useless with the iPhone 1.1.1 software upgrade . The community might be able to hack a version for 1.1.1 but without any support from almighty apple its just a cat and mouse game. With every minor release the applications

Airtel 16Mbps for Impatient Ones

This advert can be the summed as the best in terms of making fun of the impatient ones. The new Airtel broadband is 16 Mbps but with a slight hitch. At Rs. 2999/- with a Data Transfer Limit of just 20 GB. Just listening to a few hours of music videos on Youtube should be enough to exhaust the limit in no time. Thinking of downloading torrents is something one should not even think about. Not sure who Airtel is targeting with this plan. If you bought this plan do leave a comment.
