If you XULRunner apps is behind a proxy, you can set the network.proxy.* preference to make your XULRunner apps to use the specified proxy, just like in firefox.

JavaScript: Parse and escape URL query values

2009-01-07T08:05:00.001+11:00

When constructing URL in javascript, it's important to call escape() method on all the values to ensure that data is sent correctly from client to server end. Take for example, if we're trying to submit a field with the value of 'bold ' (notice the space at the end). When constructing the URL, the value of 'bold ' should be encoded to 'bold20%s'. The same goes for special

System Component Configurability

SVN and executable files

2008-08-01T11:28:00.002+10:00

SVN does not manage difference in file permission in the same way as a normal UNIX filesystem would. That is, if you create a script and forgot to chmod it, and then you add it to SVN - SVN will forever remembers it as a non-executable file. This means that, if you chmod 755 the file for example, and do svn commit, svn will not detect the difference. For that, we have to use svn propset [link].

Software Engineering: Not Just programming.

2008-07-22T10:31:00.001+10:00

If engineering a software system is mostly about programming, then in due time we will be replaced by a cheaper alternatives from places like India or China. Because programming is not difficult to do.Indeed, it is

Fork, Memory Usage on Solaris OS

2008-07-16T14:36:00.001+10:00

Traditionally, Unix has had only one way to create a new process: using a fork() system call, often followed by an exec() system call. The fork() call makes a copy of the entire parent process' address space, and exec() turns that copy into a new process.(Note: In the Solaris OS, the term swap space is used to describe a combination of physical memory and disk swap space configured for the system

2008-07-11T13:55:00.001+10:00

Today our ActiveMQ instance crashed in one of our servers - a mysterious sudden death! After digging out a bit, I find that activeMQ died because of a crash in JVM 1.6.0-b105. I know for a fact that when JVM crashed, it will dump a file of the format hs_err_pid(PidNumber).log on the current runtime directory (think of this like a C dump file). So doing a locate hs_err allows me to find this file

The biggest problem with Java is that, unlike PHP who keeps things light, crude, and simple - Java strives to solve problem in an elegantly complicated manner. As a result, the problem was never simplified in any way, but rather in the Java culture we have hundreds of Framework, each solving a particular problem in a very stylish way, but never adding much benefit to the 'language' in general.A
