Managing a big address book can be a challenge, so it's no surprise that the top request for Google contacts is a fast, easy way to merge duplicate contacts. You've been able to merge contacts one-by-one for a while, but now we've added a single button that merges all your duplicate contacts at once. To clean up your contact list in one fell swoop, just click the "Find duplicates" button in the contact manager, review the merge suggestions (and uncheck any suggestions you don't want merged), and hit the "Merge" button.

Grails can seem very slow in development mode, with pages taking more than a second to load. If this applies to you, then try increasing the maximum heap size by setting the
JAVA_OPTS
environment variable to something like this: '-Xmx512m' - this will set the maximum heap size to 512Mb when running Grails and should result in a noticeable improvement in response times.
As a workaround you can edit startGrails.bat and unconditionally put -Xmx to
JAVA_OPTS (search for related lines).
set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx512m -XX:MaxPermSize=1024m

If you want to connect to a PC via Remote Desktop (RDC), you need to know the IP address provided by your ISP. This page is an easy way to see the IP address provided by your ISP.
If you need to know the IP address of your computer on your home network, click Start > Run type cmd in the Run open box and click OK. When the command prompt window opens, type ipconfig -all to see your computer's IP address on the network, your default gateway (the IP address of your router), and the MAC address of your network card (which comes in handy for MAC address filtering on your router).

I came across this tool http://code.google.com/p/
This does not perform any profiling or stores into database, so is considered lightweight i.e. should not degrade a lot performance-wise. ( http://groups.google.com/
I decided to use it in my application which is a Struts based application in Test environment. I gave it a try by installing the required jars and modifying the web.xml Then I deployed the application and logged in to the application. I was not able to login due to some error. So I decided to check if the Java Melody page shows up. To access this I simply had to use http://server:9090/appname/
So this gave me the error I would have otherwise searched in my log file. After fixing the error (database synonym grant issue), I played with the application and turned back to monitoring page. It gave me pretty good http and sql statistics. I also liked the way it can drill down to all SQL queries
You can check out the monitoring page at http://server:9090/appname/
It can be used it to monitor application with respect to their performance, logging data etc. in real-time.

Do you ever feel like the only good desktop wallpapers you can find are the either the basic 15 or 20 Apple provides or solid colors? Do you often find yourself spending time looking for something that isn't a beautiful photograph but also isn't a gradient and drop shadowed mess with a little lens flare and some annoying copyright information in the corner?
Do you want less, but not boring? Then you want Simple Desktops.
Simple Desktops: a collection of bling, drop shadow, and gradient free desktops to help keep you stay focused but also provide just enough eye candy to not be bored. It's here because finding these around the web is just too hard.
Attribution for the creation of these is given to the creator on the site, but it doesn't extend onto your personal desktop. Use of these desktop wallpapers is for personal use only and shouldn't be sold or reposted without the expressed written consent of the desktop wallpaper's creator.
I had an interesting situation with MyEclipse not building new class files out of changed java code. It was trying to run an old copy of my application. There are a number of things you can do to fix this. Check which one works for you…
Solution:
Try and restart using -clean and see if that helps. On Mac, you will have to select the Eclipse executable and do "Show Contents" then edit the eclipse.ini file in there and add it at the top line.
Also, remove the deployment, clean your project and re-create the deployment. If it's still not working, clean the <workspace>/.metadata/.log file and retry it and see if an exception is getting reported.
Pop open your project properties for the troubled web project, and go to MyEclipse > Web and make sure the two text fields have valid Web Root and Context Root directories set.
Then go to the Java Build Path properties node and click the "Source" tab. Now double-check that your source directory or directories are setup correctly and that your output dir is set to the correct WEB-INF/classes output dir (you can use Browse to re-select it if it's blank).
Now go to Project menu, and select Clean. Make sure the project rebuilds completely without errors.
If you have errors, double-check them, they might be invalid library or project references, which will stop project building dead in it's tracks.
Project layout supported in MyEclipse: (Hopefully will be more flexible in the future)
/<project root>
+/src <-- Java source code for web project (servlets, actions, forms, beans, etc.)
+/docs <-- license files, readme's, etc
+/api <-- Target for your Javadoc source generation
+/lib <-- extra libs that the web app doesn't need while running
+/webroot <-- this is the base of the webroot, this will be the root when deployed to Tomcat, etc.
+index.jsp <-- example jsp file in root
+/images <-- images for the website
+/WEB-INF
+/classes <-- build output directory
+/lib <-- libs required for your webapp to run (i.e. struts.jar, etc.)
+/conf <-- your custom conf files that you need for your app
+/tld <-- taglibs
