SugarCRM

by: WanderingTechy June 22, 2010

I am just starting a SugarCRM install/customisation.  Its the first time I have used this so will be posting notes as I go.
I want to remove a lot of the extra cruft that shows up.  First remove some subpanels.
In
custom/Extension/modules/Accounts/Ext/Layoutdefs/layoutdefs.ext.php put

PHP Code:
<code>
unset($layout_defs['Accounts']['subpanel_setup']['leads']);
unset($layout_defs['Accounts']['subpanel_setup']['activities']);
unset($layout_defs['Accounts']['subpanel_setup']['history']);
unset($layout_defs['Accounts']['subpanel_setup']['accounts']);
?>
</code>

Obviously you need to create the folders and files if they don´t exist.
Then [...]

wp-spamfree update

by: WanderingTechy March 19, 2010

I have just received a comment to my post regarding wp-spamfree and decided to do a search for other users of wp-spamfree who had had problems.
StevoFC has some negative comments but didn’t really look into the cause of the problems.  If he had done a little research to find out why the comments were being [...]

Upgrading to php 5.2 in Centos 5.x

by: WanderingTechy March 18, 2010

To enable centos-dev, you need to create /etc/yum.repos.d/centos-test.repo and add the following
[c5-testing]
name=CentOS-5 Testing
baseurl=http://dev.centos.org/centos/5/testing/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing

Then when you
yum update php
You will get the latest version.  Please note it breaks ioncube and you will need to download the latest version from http://www.ioncube.com/loaders.php
Thanks to this comment for showing the way.

Open Source HTML Editor

by: WanderingTechy March 10, 2010

I am looking for an Open Source HTML editor to replace Frontpage which I have been using for years.  I quite liked frontpage for it’s 3 tabbed approach to pages.  I could draw tables in the design mode, go into the html mode and edit it to remove the frontpage fluff and add php code, [...]

Quick Tips – Killing Zombie Processes

by: WanderingTechy March 6, 2010

This will be a regular feature (I hope). Quick tips are brief descriptions of a common problem and a solution.
The first is how to kill zombie processes.
A zombie process is a child process that has died without the parent’s knowledge or acknowledgement.
To kill it send a signal SIGCHLD to the parent process.
kill -SIGCHLD processID

Learning C++

by: WanderingTechy October 13, 2009

I decided I wanted to get back into “proper” programming again.  I started programming in 6502 asm on the commodore 64 and then onto 68K asm on the Amiga.  I have not done any real programming since the early 90’s.  However for the last 12 years I have been developing in PHP so have kept [...]

Is WordPress Safe Part 2.

by: WanderingTechy September 7, 2009

The most common excuse I can find for not upgrading is that it breaks plugins.  Sorry but security is more important than playing a YouTube video.   This blog has gone from V6 of Wordpress all the way up to 2.8.4 when a plugin broke (once) I fixed it.
Now the wordpress team cannot test every single [...]
