lssave write IO on OS X

Analytics & Monitoring, os x, [popular],

Seeing unexpected write IO in Activity Monitor, had a look with:

sudo iotop 2>/dev/null

And lssave is the culprit. Then you want the following:

sudo /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

Or a more verbose:

sudo /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -v -lint -domain local -domain system -domain user 2>&1 | grep -v 10811 | grep -E -B 1 -A 2 "Can't|Error"

Java process maxing out CPU under VirtualBox

Virtualisation, Windows, [popular], , , ,

I got burnt by this one – all Java processes spin at 100 CPU on update 4.0.6 of VirtualBox.

A work-around is to go to Control Panel / System / Advanced / Environment Variables / System Variables and add a variable called “J2D_D3D” with the value “false”. This will supposedly disable Direct3D in Java.

via #8794 latest update breaks Java on XP guest – VirtualBox.
