Netbeans will not start? Perhaps it does!

20 Jan. 2013

Unable to start Netbeans in Ubuntu, reinstalling it doesn't help, installing a different version doesn't help, tried to install from Software Centre, install from terminal apt-get command, install using the offline .sh installer, install different bundle... no luck. From System Monitor Processes tab, it appears that the Netbeans is running, and the task appear at launcher, but I just can't find the program on any workspace. Until I found the little 3px line on one of my workspace, on one of the display.

The program window was just too small to be found. No minimum window size? Who know? Move the cursor onto it, click & drag to resize it, and now I've got my Netbeans back.

It may happens to any other software that doesn't have a minimum windows size, or on other operating system. If you have a same problem, don't reformat your pc :)

Floating Point Precision

26 Dec. 2012

When ASP CInt( ( 0.3 - 0.2 ) * 10 ) gives you 1, but PHP (int) ( ( 0.3 - 0.2 ) * 10 ) gives you 0;

When MySQL SELECT CAST( 3 * ( 1.0 / 3 ) AS SIGNED ) gives you 1, but MSSQL SELECT CAST( 3 * ( 1.0 / 3 ) AS INT) gives you 0;

How accurate the result you can expect from your web application?

When your web application is built on top of the myth of the floating point, you can't even expect 0.1 from JavaScript (0.3-0.2), it gives 0.09999999999999998...

PHP regular expression to strip/trim protocol from the beginning of an URL.

11 Dec. 2012

To remove http://, https://, ftp://, sftp://, www...

echo preg_replace('#^[^:/.]*[:/]+(www.)?#i','',$url);

Examples:

function strip_url($url){ return return preg_replace('#^[^:/.]*[:/]+(www.)?#i','',$url); } echo strip_url('http://www.ggshow.com'); echo strip_url('https://www.ggshow.com'); echo strip_url('ftp://www.ggshow.com'); echo strip_url('sftp://www.ggshow.com'); echo strip_url('http://ggshow.com'); echo strip_url('http:/www.ggshow.com'); echo strip_url('http:www.ggshow.com'); echo strip_url('http:ggshow.com'); echo strip_url('HTTP://WWW.ggshow.com'); echo strip_url('anything://www.ggshow.com'); echo strip_url('anything//www.ggshow.com'); echo strip_url('//www.ggshow.com'); echo strip_url('/www.ggshow.com');

Every echo statement above will output ggshow.com
