Du sort by size and human readable

Quick example to improve the du command output by displaying the biggest 10 subfolder of the current folder, each with its human redable size.

	
du -k * | sort -nr | cut -f2 | xargs -d '\n' du -sh | head -n 10

Simple PHP updating counter on a Bash shell

If you’re running a php script on a shell and want to know what it’s doing, at which point of the script it is you can simply use the chr function to print a backspace and updating a counter while running.

Below is a quick example

	
<?php
	$howmany = 20;
	echo "I have to do $howmany cycles\n";
	for($a=0;$a<$howmany;$a++) {
		$bkspacestring = "";
		for($k=0;$k<strlen(($a-1));$k++)
			$bkspacestring .= chr(8);
		echo $bkspacestring.$a;
		sleep(1);
	}
	echo "\nDid it!\n";
?>

[Browser] My favourite Chrome extensions

Going Mobile - Twhois Android App

twhois:

We are very proud to present you our new Android application featuring the Twhois service.

The App was realized as experiment and is still an Alpha version. It’s compatible with Android 1.5+ (tested until 2.1) and is very rough as layout.

From the main window you can type the username of a tweep you’re interested on, and then press the Twhois this button.

After a bit of loading (please be patient, we still need to put the loading animation) you will retrieve exactly the same data presented on our main website. Avatar, full name, company and role details, a short biography and obviously the Social networks profiles of the desired user. As show below data are presented very schematically.

Downloads

You can install the application directly from the Android market searching for twhois or com.ao.twhois

Alternatively you can use the following QR or download the .apk directly.

Remove unwanted profiles - part 1

twhois:

We continue working on the editing part of twhois and today we’re releasing the first part of the remove feature we were asked to implement.

Logging in via Twitter API you are now able to delete previously added profiles. This means that the red cross shown above will only be present for links you added manually from the ‘Add profiles’ button.

We’re working hard to release the second part of the script soon, so that you will be able to delete automatically imported profiles too.

While you’re waiting don’t forget to fill out bugs!
