Ever want to create collage in linux? Then Shape Collage is the answer. Shape Collage was started by Vincent Cheung in 2007 because he had thousands of photos and didn’t know what to do with them. He thought about making a photo collage with his photos, but didn’t like the existing collage making programs. They required too much work to make a collage, they didn’t look nice, and they didn’t give you enough control. He begin tinkering around and invented a new algorithm for automatically arranging photos in a collage. Vincent then realized that his algorithm wasn’t restricted to just boring rectangular collages like everyone else, and so, Shape Collage was born!

Shape Collage is the only collage maker that:

  • Optimally arranges photos
  • Creates collages in different shapes
  • Can handle thousands of photos
  • Generates super high-resolution images (up to 200 megapixels)
  • Makes collages in just seconds

Firefox Sync – Synchronise your Firefox bookmarks

Filed under Desktop, Fedora, howto, Linux, Microsoft Windows, Software, System, Ubuntu, Windows 7, Windows Vista, Windows XP by on September 2, 2010 at 10:00 am {3 comments}

Ever want to sync Firefox bookmarks, and browsing history between your office PC & Home PC, then Firefox Sync is the answer. Firefox Sync (formerly Labs/Weave) gives you secure access to your bookmarks, open tabs, and browsing history from any computer, as well as mobile Firefox and Firefox Home for iPhone.
With Firefox Sync you can access your history, passwords, bookmarks and even open tabs across all your devices.
Firefox Sync is available for Firefox 3.5 and 3.6. If you are using Firefox 4 Beta, Sync is a feature and you don’t need to download the Add-on.

Install and set up a Firefox Sync

  1. Go to the Mozilla Add-ons Firefox Sync page, and click Add to Firefox.
  2. When you have finished installing Firefox Sync, click Restart Firefox. Firefox will restart with the Add-ons window open.
  3. In the Add-ons window, click Preferences to open the Sync panel.
  4. Click Set Up Firefox Sync
  5. Click I’ve never used Sync before.
  6. Create a username and password. Enter your email address, and check “I agree to the Terms of Service and Privacy Policy”. Click Next to continue.

  7. Create a secret phrase, then click Next.

  8. Choose what information to sync. By default, Firefox Sync will sync everything. For Advanced Users, if you really want to customize your settings, you can Click on Sync Everything and set it to Use my custom settings to pick which items to sync, then click Next.

  9. Enter text from the image, then click Next.
  10. You will see a Setup Complete! message. Click Finish to close the setup window and take you back to the Sync panel.

  11. You do not need to do anything else. Firefox Sync will automatically sync your data in the background from here on. Note: The sync should happen very quickly but may take up to 24 hours.
  12. Make sure the initial sync has completed before you use Firefox Sync on another device. To see if the initial sync is complete, mouse over the Firefox Sync icon in the bottom right corner of the Firefox window. A tool tip should appear with a Last Update time. If there isn’t a time listed or the time is a while ago, the Firefox Sync servers will not have your most recent data.

Installing Firefox Sync on another computer for sync

  1. See steps 1-3 above.
  2. In the Sync panel, click Set Up Firefox Sync.
  3. Click I’m already using Sync on another computer.

  4. Enter your Firefox Sync username and password, then click Next.

  5. Enter your secret passphrase, then click Next.

  6. You will be asked to choose what to do with the data.
    • Merge this computer’s data with your Sync data- this option combines the Firefox settings stored on the server with those on this computer.
    • Replace all data on this computer with your Firefox Sync data- this option allows you to restore your Firefox data from the server copy. Great for when you are setting up a brand new computer, for example.
    • Replace all other devices with your local data- this option will erase the settings on all of your other copies of Firefox and replace them with the ones from this computer.

  7. Choose suitable option & press next
  8. Click Next, then confirm to start syncing your data. You can view your Firefox Sync status in the bottom-right corner of the Firefox window.
