PHP: Quick tip on setting up server-side logger
October 30, 2007 § Leave a Comment
Changes in php.ini:
- Around line:416: uncomment error_log variable, and assign it to your prefered logfile.txt. For example, on Windows box: error_log = “C:\log.txt”. Beware: make sure that PHP has permission to modify the log file on *NIX system.
- If you want to NOT displaying PHP error on the screen: Around line 360, make sure that: display_errors = off
Grunt work required to make sure that things are logged properly:
use if block:
if(something->bad->going->to->happen)
{
//call this system function
error_log(‘the message why this is bad’);
}use try catch:
try
{
//do something that’s possibly bad
}
catch(Exception $e)
{
error_log(‘Exception thrown: ‘.$e->getMessage());
}

- And, specific periodical scripts, usually under /etc/periodic/{x}, where x is daily, weekly, or monthly
What can you do with this script?

The innovator is Jefferson Y. Han who got the inspiration from a phenomenon called “Frustrated Total Internal Reflection”.
The wall screen looks super awesome, very much like Tom Cruise’s movie, Minority Report.
Big ass touch screen monitor that allows collaborative works is no longer science fiction.

Javascript: setTimeout() vs setInterval()
October 11, 2007 § 1 Comment
What is setTimeout():
It is a function that can execute other javascript statement AFTER x interval. The interval unit is millisecond.
Syntax:
setTimeout(“do.something();”, 1000); //Execute do.something() 1 second later.
What is setInterval():
It is a function that can execute other javascript statement EVERY x interval. The interval unit is millisecond.
Syntax:
setInterval(“do.somethingElse();”, 2000); //Execute do.somethingElse() every 2 seconds.
Notes:
Use clearTimeout() to cancel setTimeout(). Similarly, clearInterval() is used to cancel setInterval().
When calling “this” inside setTimeout() or setInterval(), it refers to window(global) as opposed to the object you are calling the function from.
