Optimizing Wordpress – Tips for Speed

Image via Wikipedia

Wordpress is crap, but it is the best crap we can get. When your website, with Wordpress sitting in the back, starts to pick up traffic, it will slow down and become unresponsive. Adding hardware will help, but correctly implemented load balancing and load distribution across more than one computer can be tricky and expensive. Trying to optimize Wordpress and the web server itself usually gives better short-term results. In the long run even this won’t help and it will just postpone the inevitable, you will have to cluster in one way or another. I am not going to talk about clustering and load balancing today, I will focus on optimizing your Wordpress. Newbie friendly, yet hardcore, meaning that I will provide explanation for all the complicated stuff.

Eclipse runs “File Search” when pressing AltGr+G

Did you ever have any problems with Eclipse? With initial versions of Galileo¹ and in previously released Gynamed there was a problem with preassigned keyboard shortcuts on some locale’s². The problem that Eclipse created when using Slovene keyboard layout was that while programmer wanted to type the ] key, Eclipse run File Search action.

Slovenian users are not to blame that their keyboard has ] key mapped to AltGr+G key combination. And Eclipse developers could browse through Wikipedia to discover what obscure keyboard layouts exist.

Any competent programmer will notice that with the default key mapping Eclipse guards programmers from using too many arrays since typically array is marked with [] key combination. They are advancing object oriented design and programming. But in some cases arrays actually make your code faster and optimize memory usage and fragmentation.

XMLbeans scomp fails with “java.io.IOException: CreateProcess error=2, The system cannot find the file specified”

If you are using xmlbeans on Windows to bind your schema to Java types then you are probably using a tool bundled with the distribution called scomp or Schema Compiler. For schema compiler to work you will need to correctly setup computer environment by installing JDK. You can follow through the following check-list to detect if any additional installation steps are required on your machine setup:

• Start->Run->type cmd and type java in the command line. If no error then your setup is correct; otherwise setup JAVA_HOME and add %JAVA_HOME%/bin to your Path environment variable and try again.
• Start->Run->type cmd and type scomp in the command line. If no error then your setup is correct; otherwise setup XMLBEANS_HOME and add %XMLBEANS_HOME%/bin to your Path environment variable and try again.

Then run scomp. Depending on your wishes you will probably wan’t to create a .jar file of the Java types scomp compiles from schema files. I used the following command line:

scomp -d schema -src src -out my_schema_1_0_0.jar ./schema/mySchema.xsd

where mySchema.xsd file was stored in ./schema folder.

If you get my_schema_1_0_0.jar, by some coincidence then kudos to you, but most likely you will end up with something similar to this error:

Time to build schema type system: 1.282 seconds

Time to generate code: 18.687 seconds

Star Trek Online – Characters and Space Combat

Star Trek Online was one of the more, if not the most, anticipated games¹ here at Three Wise Men. That is right, we are all trekkies, we are sure that miniskirt uniforms were dropped because crawling in Jefferies Tubes could become a bit awkward. We also know that crossing replicator power converter with plasma manifold isn’t something you should do if you want to keep your plasma relays in a working order.
