NetBeans on Windows 7 x64

NetBeans 7 has a problem under Windows 7 x64. When trying to start it, it only says:

JVM creation failed.

Just adding “-J-Xmx256m” to the netbeans_default_options, and thus not relying on the default value, solves the problem.

GRE® POWERPREP with Windows 7 Pro

Everybody who finds himself in the situation that he or she has to take the GRE General Test will receive a CD with the GRE® POWERPREP software from ETS a few days after registering for the test. Alternatively, the software can be downloaded from the ETS website.

However, it only works with Windows OS up to XP. With Vista users experienced a lot of trouble trying to install POWERPREP, but using the compatibility mode they were able to start and use the test prep material. Nevertheless, using Windows 7 I could not accomplish to get it startet, even with the compatibility mode: the window just flickered and nothing else happened.

A possible solution for those, who do not want to install Windows XP on a separate partition, is the new Windows 7 XP mode. The XP mode offers the capability to run a Windows XP environment from your Windows 7 desktop. It therefore requires a processor with the Intel® Virtualization Technology or AMD-V™ turned on and Windows 7 Professional or higher. The Intel® Processor Spec Finder helps to find out whether your (Intel) CPU meets these requirement.

If so, you can download Virtual PC and the XP mode installer. After the installation a reboot is required. Within the XP mode POWERPREP installs and runs smoothly.

WordPress, and Server Error 500

Like others, whose webhoster is 1and1 and who use WordPress, I experienced a lot of problems with some very popular plugins, such as qTranslate or NextGen.
After activating the plugin, an

Internal server error 500

occured whilst using the admin panel, even preventing me from deactivating the plugin. In this case, there’s only one option left: connect via FTP to your webserver, change directory to your WordPress root, and in wp-conten/plugins rename the plugin directory. This way, WordPress won’t find it anymore and will deactivate the plugin automatically.

But, of course, there has to be a workaround, instead of simply not using certain plugins. The following activates PHP5 on your webspace and worked out perfectly for me:

  1. Open (or create) a .htaccess file in your WordPress root.
  2. Add these lines:
    Options All -Indexes
    AddType x-mapp-php5 .php
    AddHandler x-mapp-php5 .php
