GRUB error: invalid signature

Posted 15 Mar 2010 — by Arun
Category Linux, Ubuntu

I have a dual boot system with Ubuntu 9.10 and Windows 7. Everything was working fine until last week. I tried to boot into Windows and I got Invalid Signature error when I selected Windows in the GRUB menu. Ubuntu part worked fine. After Googling, this is how I fixed it.

Open a terminal (Application – Accessories – Terminal). Type the following commands (highlighted in BOLD) one by one in the terminal and press enter. It will ask for password the first time you try. Enter your login password.

  • sudo apt-get install os-prober  (If it’s already installed, then fine)
  • sudo os-prober    (It should find both Ubuntu and Windows)
  • sudo mv /boot/grub/device.map /boot/grub/device.map.bak  (Take a backup)
  • sudo update-grub

Exit the terminal by entering exit. Reboot the system and it should work fine.

Opera mini 5 beta for Android is cool

Posted 14 Mar 2010 — by Arun

I used Opera mini 4 or whatever the previous version was and I didn’t like it. I then tried Dolphin browser. I did like it, but I quit using it since it was buggy at times. I had to fall back on the default browser, which though I like, was missing something. I downloded the new beta of Opera mini 5 and I love it. It’s easy to work with multiple tabs and it loads pages pretty fast. The only disappointment for me is, there is no option to share pages. Oh! I forgot to add pinch to zoom to the disappointment. If they add those two, then it’s rock solid browser.

Microsoft Tag for Android

Posted 04 Mar 2010 — by Arun
Category Droid

I finally downloaded a Microsoft apps onto my Droid. Microsoft Tag is now available for Android. Microsoft Tag is more like a barcode reader. According to Microsoft, From your mobile phone, simply snap or scan a Tag image anywhere you see it – in editorials, advertisements, product packaging, signs and storefronts – and gain instant access to Websites, videos, reviews, schedules, contact information, social networks, discounts, promotions and more! All you need to do is download the free Tag reader on your web enabled camera phone and when you see a Tag, snap or scan it to interact with the world around you in new ways!

You can download Microsoft Tag by searching Microsoft Tag in the Android market. I installed it today, but haven’t gotten a chance to scan anything. Will try it soon.

Gesture Search for Android from Google

Google Lab has introduced a new feature called Gesture Search for Android. Once you install the application from Android Market (search for Gesture search), Start it and it’ll inform you how to activate the search. I installed it and tried few options and it worked great. It showed the search results from contacts, bookmark, applications, music tracks etc.

You can search by entering multiple characters and you can delete the last character by swiping from right to left at the bottom of the screen and you can delete the entire search query by swiping from left to right. It’s pretty cool. Give it a try. The only issue is, it works only with devices running Android 2.0 or later, so majority of Android phones are ruled out.

How to play m2ts files smoothly using VLC

Posted 02 Mar 2010 — by Arun
Category Technology, Ubuntu

I recently bought a Panasonic HD camcorder which records the videos in m2ts format. m2ts is a high definition MPEG format used in Blu-ray discs and AVCHD. After I copied the files to my desktop, when I tried to play the video using VLC, it was jerky. It wasn’t smooth at all. When I played the video using the Panasonic supplied HDWRITER software, it was smooth. After Googling, I got VLC to play the video smooth. All you have to do is, go to Tools – Preferences in VLC, select Input & Codecs option and select ALL from the drop down menu for Skip the loop filter for H.264 decoding (picture below). Save the preference and play the video. The video should be smooth and perfect. I tried this in Ubuntu 9.10, but it should work with all OSes.
