I found nice jQuery plugin for generating QR codes written by Jerome Etienne: jquery.qrcode.
It’s fairly easy to use. Just pass a text to function and QR code is ready:
jquery('#qrcode').qrcode("this plugin is great");
Here is small application that generates QR codes on the fly as you type.
You can also download QR code as image (use: Chrome, FF, Opera or Safari for download).
Link to standalone QR code HTML5 application.

jQuery.i18n.properties is useful library based on jQuery. You can use it to load .properties files with localization to web application.
I made upgrade of jQuery in my application from version 1.6.2 and application failed with error:
Uncaught SyntaxError: Unexpected token ILLEGAL
I spent some time debugging jQuery and i18n and I found out that one of .properties file contains weird property with name:
1_guide=1 guide
Problem was in numeric prefix. Solution is quite easy: fix property.
one_guide=1 guide
This problem occurs when you upgrade jQuery to 1.6.3 and higher.
Feel free to join this meeting.
Flash Player for mobile browsers won’t be in development anymore. This is not big surprise in my opinion.
Adobe shifted focus to AIR for mobile and HTML5. It is possible to build native apps for desktop and mobile with AIR.
Note: Development of Adobe AIR for Linux was cancelled during summer 2011. AIR supports Mac, Win and mobile devices.
You can read more about this game changing decision at Adobe’s blog.

Jan Volf wrote Pexeso framework. Pexeso is component based, event driven PHP View-Controller framework similar to Adobe Flex framework.
Developer can reuse patterns and Flex style of writing code even when coding in PHP.

I was building application based on jQueryMobile.
It worked correctly in all modern browsers except Internet Explorer. Application was displayed incorrectly and it was not functioning at all.
Solution to this problem was quite easy. I forgot to specify following line in the beginning of document:
<!DOCTYPE html>
Application started to work correctly also in IE after this small fix.
