A database-ERD (+more) diagram tool (like visio)

Another recommendation from JJ.

Dia is roughly inspired by the commercial Windows program 'Visio', though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.

Windows 7 - Missing drives (especially empty USB)

From http://www.pp.co.nz newsletter

Show all of your Drives in Windows 7 Explorer
Depending on your system settings, when you go to computer in Windows Explorer, you might be in for a shock –> you may not see all your drives such as memory card readers if those drives are empty. If this disconcerts you, there’s a simple way for you to see them even if there’s nothing there:
1. Launch Windows Explorer and move below back-forward button and click on organize –> Folder and Search Options and move to View tab.
2. Under ‘Advanced settings’, uncheck box next to ‘Hide empty drives in Computer folder’. Click OK.
3. The empty drives would now be visible.

Google’s Do-It-Yourself App Creation Software

Google is bringing Android software development to the masses.

The company will offer a software tool, starting Monday, that is intended to make it easy for people to write applications for its Android smartphones.

The free software, called Google App Inventor for Android (http://appinventor.googlelabs.com/about/), has been under development for a year. User testing has been done mainly in schools with groups that included sixth graders, high school girls, nursing students and university undergraduates who are not computer science majors.
