How to Stream Movies to your iPhone or iPad

I have just found a way to successfully stream movies (avi, mkv, mp4, etc) to my iPhone. It’s via an app called AirPlayer.

First, set up a media server on your home network (for example, PS3 Media Server, like what I have explained in my previous post, “How To Share Media Between PlayStation 3 and Linux”). Then, just access your movies through the AirPlayer app. Everything just works, without much setting or config changes.

Create Your Own Web App to Execute Linux Command

Let say you need to run a command (which you use frequently) on your headless Linux box, such as, copying files, start/stop services, reboot, etc. However too lazy to go to the physical machine or open a ssh command from another pc.
Would it be nice if we have a web application that can easily be accessed through a web browser (even from a mobile web browser), to execute those commands. All we have to to is type the url (http://my-server-ip-address:myportnumber), and click on a link.
All these could easily be achieved using very simple service using Python.

1. Create a simple Python script. The Python script will be using WSGI to serve HTTP request/response.


2. A sample of the Python script below:

import os
from cgi import parse_qs, escape

def hello_world(environ, start_response):
    parameters = parse_qs(environ.get('QUERY_STRING', ''))
    if 'type' in parameters:
        mycommand = escape(parameters['command'][0])
        mycommand = ''
    start_response('200 OK', [('Content-Type', 'text/html')])

    if mycommand == 'copyfile1':
	#your linux command here. Example below
	os.system('cp myfile1.txt mynewfile.txt')
    elif mycommand == 'copyfile2':
	os.system('cp myfile2.txt mynewfile.txt')

    return ['''Command to execute:  %(mycommand)s 
    <a href='?command=copyfile1'>Copy file 1</a>
    <a href='?command=copyfile2'>Copy file 2</a>
    ''' % {'mycommand': mycommand}]

if __name__ == '__main__':
    from wsgiref.simple_server import make_server
    #put your own server ip address and port here
    srv = make_server('',81, hello_world)

3. Make the Python script run on every startup. Create a bash script for this:
vi myserver

4. Here’s the script for the bash file:

#! /bin/sh
# /etc/init.d/myserver

# Carry out specific functions when asked to by the system
case "$1" in
    echo "Starting myserver "
    python /home/username/
    echo "[OK]"
    echo "Stopping myserver "
    kill -9 `pidof python`
    echo "[OK]"
    echo "Usage: /etc/init.d/myserver {start|stop}"
    exit 1

exit 0

5. make the bash script executable.
chmod +x myserver

6. copy myserver script to /etc/init.d
sudo cp /wherever/you/saved/myserver /etc/init.d/myserver

7. update the startup folders to include the new script.
sudo update-rc.d myserver defaults

8. To test your Python web app, open a web browser, and type:

Playing 1080p Video in Ubuntu Without Lag

I have not-so-bad specs for my laptop:
– Dell XPS M1530
– Intel Code 2 Duo CPU 2.40GHz
– Running Ubuntu Karmic Koala 9.10

I have no problem running 720p .mkv HD video files. No lagging, no dropped frames whatsover. However, when running 1080p .mkv files, especially those big sizes full-HD Blue Ray medias, I have:
– Lagging,
– Dropped frames,
– 100% CPU utilizations.

It doesn’t matter if I’m using VLC, or Totem Movie Player, it will always have those problem above. From what I’ve read, this is probably due to FFMpeg codecs for H.264 decoding.

However, I have a solution, found from

Below are the steps:
1. Install mplayer:
sudo apt-get install mplayer-nogui

2. Run your 1080p .mkv files with it:
mplayer -vo vdpau -vc ffh264vdpau /path/to/the/mkv/file

Now the HD movies playing in my Ubuntu laptop are smooth as it can be.
Try it out. Cheers.

How to Enhance Your Linux Desktop with Conky

I have been using Conky as my desktop monitoring widgets for quite some time now. Before this, I’ve been using few applications like screenlets and gdesklets, but there’s a lot of drawbacks on these applications. Among them were limited customizations, it’s difficult to develop your own widgets, unable to find widgets you’re looking for, and if you do find them, they are too buggy to be used in the first place.

Then, I’ve found Conky. I’ll never turn back.

This is the best system monitor I have ever experienced. It is highly customizable, all you have to do is modify the Conky config file. There’s a lot of widgets/variables to use, such as system monitoring tools (CPU, RAM, SWAP, Hard Drive, etc), batteries capacity, networking, and more. And best of all, it is very, very easy to create your own widgets. If you know any programming language such as Python, Perl, or even a simple Shell Scripts, then you’re off to create your own.

Twitux and gTwitter: Twitter Clients for Ubuntu Linux

Following my previous post on Twitter, I’ve just beginning to get involved with Twitter.
Below are a couple of Twitter clients that I’ve used in Ubuntu:

A Twitter client for GNOME.
Twitux is a lightweight client for the twitter messaging service, featuring time-line auto updating, a tray area icon and notification of new messages.


Client for tracking and posting to twitter.
gTwitter is a client for posting and fetching updates to the twitter service.


Installation is available through Synaptic Package Manager. Just do a search for the application name, twitux or gtwitter.
