The Openshift is the Paas cloud environment using Cgroup of SELinux. It is
opensource software and the Openshift online provides free server.
Everybody may guess if development is easier, then performence become worse.
But by developing Alinous-Core, actually no problem about bad performance.
Alinous-Core is written in Java language, and using connection to PostgreSQL
via JDBC. And Alinous-Core use precompiled statement as possible as it can.
Almost all SQL are executed as precompiled statement.
If you are going to use precompile statement in Java or other language, you

And recently, when we do SEO, server response speed is required. If the data
transferred through the network is light, the server response speed become
I've almost finished to make tutorial of testing automation for jQuery
examples. In this process, I found some of them are not ready for that.

which is out of the web browser.
The most easy way to make the web application ready for the xpath is to add
attribute which means the identifier of the element.

Today added document about Thread synchronization.
In Alinous-Core, synchronized block, list like java, is available.
This block has 2 ways about usage.
standard synchronized blocknamed synchronized blockThe detail is simply
written in the document.
This function will used frequently used in Rich Client UI using jQuery.
Because conflict of resource access is big enemy for the Rich Client UI.
And I consider distributed servers, such as clustering web server using cloud
computing. This lock is available in the tomcat cluster.
