Lately I’ve been trying to run some load scripts that basically take data from mySQL and convert them to a Redis Luke Protocol. Part of the reason why I wrote it in Java was because the cached object needed to be Java serialized.

I ran into some issues while running some tests. It seems that my Eclipse memory heap was not big enough. Here are steps to increasing it.

1. Open Eclipse
2. Eclipse > Preferences > Java > Installed JREs

installedJre

3. Select the current JRE
4. Select “Edit”
5. Modify the default JVM properties to something like:
-Xms512M -Xmx1024M

Problem
While working on a project, I had left my computer on to go grab some dinner and when I came back, I attempted to use the Rectangular Marquee Tool, but all I could see was a hand. I tried switching tools, for some reason I was still able to lay down guides, but I couldn’t move them, closing/re-opening the file, restarting the application, and then I finally searched online and found the solution.

Solution
Try changing the workspace from the Window menu. I changed it to “Essential” and that brought back all my functionality
