With previous releases of your AIR application you needed to provide a certificate  obtained by a corporation and us "individuals" had to go without having our applications signed. Now all you need is an government issued ID to pbtain your own certificate.

Check out this unique tool, used for making mockups in seconds. I have used the online demo version and am definitely getting my hands on a copy of this. The tool allows you to create mockups of website layouts, application and so much more. It has a very easy to use components panel. Just drag and drop and save. The best feature of this tool is the way it auto aligns the components when dropped on the stage. Once you have a layout, just save and edit whenever you want.

"Never waste a minute

Mockups For Desktop allows you to work on your UI wherever you are, regardless of your Internet connection. It works on planes, at coffee shops, and wherever you like to do uninterrupted work. Import and Export features ensure seamless integration with all the other versions of Mockups, for when you get back online. Plus you can load and save multiple mockups files, use all keyboard shortcuts and lots more."

A new version of feedalizr has been launched, and has been rewritten from the ground up.

New feedalizr features:

• Offline support - SQL Lite is used for offline storage, meaning all data that has been retrieved, is stored and is available offline.
• Full twitter support - feedalizr is now a full twitter client, allowing replies, favouriting and direct messages.
• De-duplication - this is handy if..... ie, you are a friendfeed subscriber and you have a twitter account. Without de-duping, this would have meant that you would see the same entry in your friendfeed stream as well as in your twitter stream. Duplicates are now flagged, and are displayed in a minimized view. This works across all duplicate content, be it twitter/flickr/jaiku etc.
• Better memory management. Adobe Air apps have the reputation to be memory hungry, but feedalizr is optimized to run as lean as possible.
