I am pleased to finally report that the Centos release of Redhats 5.3 has been built and is available for download from http://www.centos.org/

The highlights of this release can be found at the following URL: http://www.redhat.com

The main areas of interest in my opinion excluding critical secirty fixes are:

  • Updated hardwaresupport support for the new Intel Core i7 (Nehalem) chips
  • Beefed up virtualiseation support increasing CPU and Ram limits of Virtual machines.
  • Inclusion of the fully open sourced OpenJDK. This makes Red Hat Enterprise Linux 5.3 the first enterprise-ready solution with a fully open source Java stack when combined with JBoss Enterprise Application Platform.


For those who already have Centos 5.2 installed you can simply receive the update via Yum.

Before you do the following, check that  you do not have 3rd party repo's and the Centos-testing repo enabled.

You can display the currently enabled repo's using the following command.

$ yum repolist



Then as root at the prompt type:

$ yum update

Awk is an powerful text processing language that allows you to manipulate files containing columns of data and strings. Awk is extremely useful, both for general operation of Unix commands, and for data transformation.
 
Introduced in Recital 10 is the PIPETOSTR() function (as well as backticks `` inside strings) which can be used  in conjunction with awk to transform recital data.
 
The following links provide good tutorials on awk:

sernet.de maintain the latest Samba releases in a yum repository, allowing for an easy and painless install or upgrade of Samba on your yum based Linux distribution.

To install the latest available Samba execute the following commands at the shell:

# cd /etc/yum.repos.d
# wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo
# yum install samba

To upgrade an existing Samba install:

# cd /etc/yum.repos.d
# wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo
## Note: edit sernet-samba.repo and add the line "gpgcheck=false" otherwise 
## it will not install as it is not signed
# yum update samba

Note: These steps will install the very latest build available at sernet.de.
If you require a less bleeding edge version of Samba, use the "tested" repo. This can be found at the following URL: http://ftp.sernet.de/pub/samba/tested/rhel/5

When debugging C code it is common to write debugging to an external text file using the __FILE__ and __LINE__ preprocessor defines to trace execution flow.

Unfortunately java does not support __FILE__ and __LINE__ but you can get the same functionality with this code which can be placed in one of your libraries.
	
public static void showTrace(String msg)
{
	if (msg.length() > 0) System.out.println(msg);
	System.out.println("Trace: " + 
				   "file " + new Throwable().getStackTrace()[1].getFileName() +
				   " class " + new Throwable().getStackTrace()[1].getClassName() +
				   " method " + new Throwable().getStackTrace()[1].getMethodName() +
				   " line " + new Throwable().getStackTrace()[1].getLineNumber());
}

Recital 10 enhances the way updating tables with indexes is done. The Recital engine will now evaluate each index individually to determine if any changes being made to the row effect it. If this is not the case then the index is flagged not to be updated. This enhancement helps speed up performance of updates and is particularly noticeable in cluster/network installations.
