While searching for drupal based application, I have found Open Atrium and it looks to me very useful for different team based works. Open Atrium is an intranet in a box that has group spaces to allow different teams to have their own conversations. It comes with six features - a blog, a wiki, a calendar, a to do list, a shoutbox, and a dashboard to manage it all. Enjoy drupal!

Just being successful using GP Aloashbei 'SMS send' API with PHP. This API is in beta version and not released yet. This is really a nice and futuristic approach by grammenphone (in collaboration with Microsoft). SMS can be easily send to a gp number from a web application, all you need is to register your number at first at gp aloashbei site. I will upload my code and class soon. visit https://www.aloashbei.com.bd for details.

Just wrote a program to fetch image from Flickr using Flickr API and watermark text on it by PHP. There are many applications for transferring flickr images to facebook, but found no application for transferring facebook images to flickr. Soon going to work on it.

I have used a nice, simple script to export the rrd values into excel using PHP 5. You can find the script here:

http://code.google.com/p/php-excel/

Here is my code for the rrd export (here you'll find two functions - calculate_rrd() and format_bits(), these are described in my previous blog):

/*
Author: Md.Monjurul Hasan

Description
- RRD data exporter - output values into excel file
*/
/***************included files*******/

#include the export-xls.class.php file
require('export-xls.class.php');

$filename = 'rrd_export'.rand(0,10000).'.xls'; // a random filename chosen
#create an instance of the class
$xls = new ExportXLS($filename);

//read config file and get variables
$rrd_array = array ('rra/test1.rrd', 'rra/test2.rrd');
//export to excel
$header = " RRD Export"; // single first col text
$xls->addHeader($header);

#add blank line
$header = null;
$xls->addHeader($header);

#add 2nd header as an array of 3 columns
$header[] = "RRD Name";
$header[] = "Cur In";
$header[] = "";
$header[] = "Cur Out";
$header[] = "";
$header[] = "Avg In";
$header[] = "";
$header[] = "Avg Out";
$header[] = "";
$header[] = "Max In";
$header[] = "";
$header[] = "Max Out";
$header[] = "";
$header[] = "95% In";
$header[] = "";
$header[] = "95% Out";
$header[] = "";

$xls->addHeader($header);

$count = 0;
for ($c = 0; $c < count($rrd_array); $c++) {
$ret = calculate_rrd($rrd_array[$c], $graph_type); // graph type is daily/weekly/yearly and monthly
$row = array();
$row[] = $rrd_array[$c];
$result = format_bits($ret['current_in']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['current_out']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['average_in']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['average_in']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['max_in']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['max_out']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['percentile_in']);
$row[] = $result[0];
$row[] = $result[1];
$result = format_bits($ret['percentile_out']);
$row[] = $result[0];
$row[] = $result[1];
$xls->addRow($row);
}
//output the excel file
$xls->sendFile();

?>

I needed the rrd values in tabular format rather than graph. So i fetched the rrd values using rrd_fetch() function of PHP-RRDTool API. Then I calculated the required Current, Average, Max and 95th Percentile using the following function which may save time of others:

For percentile calculation, I followed the following article:

To represent the values in bps/kbps/Mbps, you can use the following function:

/***
Function format value from bit to bps/kbps/Mbps

@input : bits
@output array: array[0] = value
array[1] = bps/kbps/Mbps

***/
function format_bits ($bits) {
$round_precision = 2;
if ($bits < 1000) {
$result[0] = round($bits,$round_precision);
$result[1] = "bps";
}
else if ($bits >= 1000 && $bits < 100000) {
$kbits = $bits/1000;
$result[0] = round($kbits,$round_precision);
$result[1] = "kbps";
}
else {
$mbits = $bits/(1000*1000);
$result[0] = round ($mbits, $round_precision);
$result[1] = "Mbps";
}
return $result;
}
