Life by Bits & Numbers

This is more of a personal notes for myself but I am sure others will find it useful.

Apache:

/usr/local/apache/logs/error_log

All exceptions caught by httpd, along with standard error output form CGI applications are logged here.  The first place you should look when httpd crashes, or you incur errors when accessing a website.

/usr/local/apache/logs/suexec_log

Contains auditing information reported by suexec each time a CGI applicaiton is executed.  If you receive an internal server error, with no relevant information being reported to the Apache error_log, check here for potential suexec policy violations.

Domain specific access logs are located here:

/usr/local/apache/domlogs/

PHP

To find out which php.ini is used for PHP configuration (to save you frustration of editing a non active php.ini) find it with the following simple command:
php -i | grep php.ini

where -i switch is used to give you PHP information (obviously). To see other useful switches run

php -h

to locate where php is use:

which php

(but you already knew this – right ?   )

*** Some of these tips are applicable not only to CentOS and cPanel configuration.

As I already wrote, BlackBerry development is not a lot of fun.  Not only you basically can not develop in Linux and OS X (although there are some workarounds, it makes the process even more painful than it already is). But you will also have problems with 64 bit operating systems. RIM is in a position that they do not officially support 64 bit systems.

The main problem with 64 bit Windows 7 for me was that I can not close the simulator (or actually the “fledge” application that runs the simulators). There are 2 possible solutions to this problem:

1. Kill the task through task manager
2. The simulator should close if you are in debug mode and you disconnect the debug session

There is also another inconvenience which is caused by your cautiously guarding Windows system. It will warn you every time that (Oh my!) fledge will change something on your computer. You know – the standard User Control Account message. To avoid that message always popping up, you will have to adjust your setting in User Control Account panel. Hit “Windows” then just type UCA, you will get it. Adjust it to the minimum and you’r good to go.

I just could NOT not to post it. I am trying to do a rationality in multi agent systems research nowadays. This speaks to me and these guys rock!

I hope the robots remember those us that helped make them what they are and keep us around to do all those jobs that they don’t want to do. Christopher Amato
