After installed fedora 14, the eclipse won’t load any plugin. The reason is memory settings in /etc/eclipse.ini is not big enough.
And then, you may need to start eclipse using root from command line. It will failed, but after that, you can start eclipse from gui normally.
Not quite convenient due to missing cursor key.
While working with the system installed tomcat6, we have to change files in /usr/share/tomcat6/conf to global read/write.
It is because open file limit is not enough. After change open file limit to 10000, it works fine.
Add a file in /etc/security/limits.d/, say nofile.conf
* soft nofile 1024 * hard nofile 65535
Edit /etc/pam.d/login, adding the line:
session required pam_limits.so
we can change the open limit by:
ulimit -n 10000
show current file limit:
ulimit -n
show all limit:
ulimit -a
show all hard limit:
ulimit -aH
There are only 15 days left for Fedora 11 hitting the road. However, there is still a major bug for me have not fixed: both svnkit and javahl not working, this renders eclipse without svn support.
After today update of my rawhide, now it shows fc11.

Zend Framework now approching version 1.8. Yesterday, it put the 1.8 alpha available for download. Also, the reference guide document has been updated including the feature of version 1.8.
It added 4 new components: Zend_Application, Zend_CodeGenerator, Zend_Tool_Framework, Zend_Tool_Project. Also, It supports more service like Zend_Service_Twitter and may be more.(I am not sure, because I have not checked what services included in previous versions).
Zend_CodeGenerator, Zend_Tool_Framework, Zend_Tool_Project looks like make up a tool chain to support Zend_Tool_Project, which looks like a command line tool can create the Zend Frame project sketch. In 1.8 alpha, it is hardly functional. What I can find out is just a zf.sh included in the bin folder, which you run
zf.sh create project ~/workspace/test
will create a default site struct in the given folder. However, the code generated has syntax error. (doule <?php), also, I can not figure out how to create projects using modules.
Most interesting part is the Zend_Application. It abstracts and wrap the common bootstrap procedures, so you don’t have to code the almost the same bootstrap file for each project.
I am doing a test project using Zend_Application bootstraping. Check out at:

Different from what we discuss before about regular variable type, object assignment always by reference:
class A {
public $a = 'a';
}
$a = new A();
$b = clone $a;
$c = $a;
$b->a = 'b';
echo $a->a, "\n";
$c->a = 'c';
echo $a->a, "\n";
Output:
a c
We use clone to make a copy of object. Please note that default clone operation is shallow copy. You have to overload the __clone method if you want deep copy of the object.
