Black Screen on LogMeIn Remote Session

by Bruce on August 25, 2010

I’ve had trouble with getting only a black screen when trying to remote control some of my computers with LogMeIn.  LogMeIn support only suggested I update to the latest version.  It happened again so I poked around in the settings and found under “Remote Control Settings” -> “Default Remote Control” it was set to Active X.  I changed it to Java, told LogMeIn to restart, and it worked.  It’s important to note that this setting is available remotely, as is the restart of the service.

Friend or Servant

by Bruce on August 6, 2010

In John 15:15 Christ states that “the servant knoweth not what his lord doeth” and that for his friends he makes known all things he has heard of his father.

How are you treating others?  How are you treated?  Friend or Servant?

java.lang.OutOfMemoryError: PermGen space

by Bruce on August 3, 2010

How to resolve the …OutOfMemoryError: PermGen error in a Tomcat/Eclipse environment.  This post does not cover how to determine the amount of memory your application needs.

Eclipse:

  • Double-click your server
  • click “Open launch configuration”
  • click the arguments tab
  • add or modify the MaxPermSize VM argument
    -XX:MaxPermSize=128m
  • you might also review the initial (xms) and maximum (xmx) heap size while you’re there.  However, the error message is specific to MaxPermSize, not these arguments.
    -Xmx512m -Xms128m

MaxPermSize specifies the the maximum size for the permanent generation heap

Coucho and the JavaHowTo blog have adequate articles.
If you are running windows and update 21 of the Sun implementation you might be running into this problem.

Tooth… String… Not

August 2, 2010 Family

Daughter #1 had a loose tooth, her last baby tooth, for a long time, 6 months.  In fact, the permanent tooth was already in place and just as big as the baby tooth.  Mom told her she needed to get it out before her dentist appointment or we’d have the dentist take it out.  She didn’t care […]
