IntelliJ shortcuts vs Eclipse shortcuts

Recently, I started to work with IntelliJ. But, honestly, after several years with Eclipse, it's hard to be effective because of key shortcuts which are different between the two IDEs. A little request on Google and I found this (great!) :

Description Eclipse shortcut IntelliJ Shortcut
Navigate a Java Type CTRL + ALT + T CTRL + N
Navigate a Resource CTRL + ALT + R CTRL + SHIFT +N
Last Modified Source ALT + Left arrow CTRL + ALT + left arrow
Debug F11 Shift + F9
Open Declaration F3 CTRL + SHIFT + B
Open Hierarchy F4 CTRL + H
Organize Imports CRTL + SHIFT + O CTRL + ALT + O
Find CTRL + F CTRL + F
Find Again/ previous F3 / SHIFT + F3 F3 / SHIFT + F3
Step Into F5 F7
Step Over F6 F8
Step Out F7 Shift + F8
Resume F8 F9
To find impl of an abstract Method ? Ctrl + Alt + B
To find usage CTRL + SHIFT + G Alt + F7

Let's SCRUM

Yes, it's time to start a new project. A classic fact is that user specifications are not yet completely defined. Humm, but I need to start the project. The only solution will be to be agile. So, let's SCRUM. It's the first time for me. I read some docs from the past but I never really tried it. Thus, I spent this evening reading charts, blogs, etc... I also found a good french video preformed by a SCRUM senior (having 4,000 hours flying on agile projects) :

Google App Engine will support Java

Excellent news! There was an empty place on the web : it was barely impossible to find free hosting for java applications. The main reason is certainly due to the runtime heavyweight. For example, a java apps consume a lot of cpu and i/o charges on JVM startup. Another reason is the total cost ownership of java servers. Let me try a little comparison : if a PHP engine is like a old car (not really powerful but strong for many usages and maintenance free), a Java engine is like a Ferrari : really performant but really horrible to manage, to tune, to maintain, etc... Now imagine that you're at the head of a low cost rental company. What should you prefer : offering PHP cheap engine or Ferrari ones? You see what I mean... But, in the other hand, what's a frustration for millions of java developers like me! I was forced to program in PHP for my webapps. (and I'm really not a PHP killer). Hopefully, graceful to Google, you will be able to have online apps using Google App Engine!!! So great, So nice, So... there's no word! Of course, I hope you will use GWT for your frontend...
