Configure your Crunchbang #!.

5 Things that I do after installing the #! and this will also help you.
If you are a developer then obviously you require more packages to install in your system.

1. Update your #! source-list to install non-free packges.

ashish@crunchbang:~$ sudo nano /etc/apt/sources.list

## CRUNCHBANG
## Compatible with Debian Wheezy, but use at your own risk.
deb http://packages.crunchbang.org/waldorf waldorf main
deb-src http://packages.crunchbang.org/waldorf waldorf main

## DEBIAN
deb http://http.debian.net/debian wheezy main contrib non-free
deb-src http://http.debian.net/debian wheezy main contrib non-free

## DEBIAN SECURITY
deb http://security.debian.org/ wheezy/updates main
deb-src http://security.debian.org/ wheezy/updates main
Now update your #! crunchbang and install 32-bit library packages which is gonna help you with the installation of skype, teamviewer, android development kit etc.

sudo dpkg --add-architecture i386  
apt-get update
sudo apt-get install ia32-libs
#! comes with linux a media player, let's install a Clementine(music player). I prefer this because of it's simplicity.

sudo apt-get install clementine

2. Change your login screen wallpaper. I don't prefer to use default login wallpaer which comes with the #!. So I change it using the below method.

ashish@crunchbang:cd /usr/share/slim/themes
ashish@crunchbang:/usr/share/slim/themes$ sudo thunar
It will open file browser where all the themes are located. Open any one of them and you will find the "background.png", this image file is used as login-background.
I'm going to use "default" theme as my login-theme.
1. Replace "default/background.png" file with your wallpaper images.
2. Rename "default/background.png" to "default/background_backup.png.".
3. Place your desired wallpaper in "default" directory and change your wallpaper name as "background.png".
4. Cross check, make sure you are doing all these stuff inside "/usr/share/slim/themes/default/" directory.
5. If you know little bit photo editing tool "gimp", then you can modify "panel.png" image(your login panel).
6. Activate the theme and logout to check the effect.
Activate : super[windows btn] + space[btn] >>> System >>> User Login Settings >>> select Theme as "default".
3. Beautify your conky.
super[windows btn] + space[btn] >>> Settings >>> Conky >>> edit .conkyrc
Replace your conky settings with the below text.

# conky configuration
#
# The list of variables has been removed from this file in favour
# of keeping the documentation more maintainable.
# Check http://conky.sf.net for an up-to-date-list.

Signature Spider at National Park.

Leave a Comment
I found this spider at Borivali National Park. When I clicked the pic I never knew that this is the signature spider, on of my friend told me about this so I googled it and here is the information. For me it's a WEB DEVELOPER who don't forget to mention copyrights on his web-site. :) These spiders make certain zig-zag pattern on web therefore also known as writer or signature spider.This spider weaves four zig zag stripes in its web, and holds its legs together in pairs. It holds its legs in pairs to disguise itself as a four legged creature; it does this to not appear to look like a spider. These spiders have many names around the world, they are known as an Argiope, a Black and Yellow Garden Spider or a Writing Spider in North America. It is known as Wasp Spider in Germany and the rest of Europe and the St Andrews Cross spider in Austrailia. They know it as KOGANE-GUMO in Japan and east asia. There are 75 different species of this spider but they all look the same. Their colours vary in between their stripes but they all keep the black and yellow stripes, They distribute also Sri Lanka, Maldives,India, Pakistan.Their habitats are Moist Deciduous forests in the sunny parts.

Alternative of google-map API, making request more than 2500.

I was looking for a free api which can help me to get latitude/longitude on the basis of Postcode.

I tested pygeocoder and other api librearies which can help me, but none of them allowed me to query more than 25,000/day cause everyone is belongs to Google.

So I did an old school coding by using Mechanize and BeautifulSoup.
I used http://services.gisgraphy.com/public/geocoding.html. It's a free, I think they are providing 30,000 requests for demo user, I didn't tested 30,000 requests cause I've 29,000 records to generate lat/long. I don't want to waste my hits for a day. I'll test and update here.

Code is not clean, cause it's a test.

Keep Coding .


import mechanize
from bs4 import BeautifulSoup 

for x in xrange(30000):

    print '----------------- searching ---------------'
    br = mechanize.Browser()
    br.open("http://services.gisgraphy.com/public/geocoding.html")
    
    add = '81100'
    con='Malaysia'
    
    br.select_form(nr=0)
    
    br.form["address"] = add
    for i in range(0, len(br.find_control(type="checkbox").items)):
        br.find_control(type="checkbox").items[i].selected =True
    br.form["country"]=["MY"]
    
    print 'hitting --- ',x
    response = br.submit()
    soup = BeautifulSoup(response)
    
    
    links = soup.find_all('li')
    print '--------- getting list ----------'
    
    li = soup.find('div', {'class': 'summary'})
    
    print '---------- looking for latitude and longitude -------------'
    list= []
    children = li.findChildren()
    for child in children:
        list.append(str(child))

    print ' found latitude and longitude at point -->  ',x
    
    latitude = list[0]
    longitude = list[1]
    
    lat = latitude[9+5:len(latitude)-5].split()
    lng = longitude[9+6:len(longitude)-5].split()
    
    print str(lat).replace(',','.')
    print str(lng).replace(',','.')

#for f in br.forms():
#    print f

Changing wallpapers in Crunchbang #! Linux .

Leave a Comment
I'm using crunchbang #! when it was #!-9 around in 2010 , now using #!-11. Between these period I tested out many linux distros but never feel that any linux is stable as #! is now, because it drops Ubuntu and using Debian-stable :) .
As per the heading of this post to change wallpaper in Crunchbang we need to copy paste the wallpapers( images ) into following directory./home/[username]/images/wallpapers/shared/
But "shared" folder is locked, so we need to copy-paste the images as a "sudo" user. Please Follow the steps.
1 Press "alt+f2" then enter "sudo thunar" and enter your password.
2 Now copy your wallpaper(images) and paste it into "/home/[username]/images/wallpapers/shared/" directory.
3 "Right-click" on the desktop and navigate to " settings > Choose Wallpaper ".
4 Now you can easily see the images and set the wallpaper by selecting images and clicking on "apply" button.

Here is my wallpaper link

Wait for the next crunchbang post. Keep Coding :)

Network Manager not running on Ubuntu12.04 at boot-time

Leave a Comment
I was configuring PPPOE connection manually by command line using "sudo pppoeconf", and by mistake I changed some settings. So after I restarted my laptop, I was getting an boot time error "waiting for network configuration" and after some time "waiting upto 60 seconds more for network configuration.."
Also there are possibilities to get this error while upgrading the system.
I solved these problem by using 2 methods.
After logged into Ubuntu.
Open terminal, type
First : not a permanent solution
  sudo /etc/init.d/network-manager start
Second : permanent solution
  sudo gedit /etc/network/interfaces
And remove the lines after
  auto eth0
  iface eth0 inet loopback
Make sure to save the file before closing it.Reboot the system

Sending Email : Django Terminal Test.

1 comment

While I was making contact-us form in PHP for my client then I thought about to do same in Djago-Python. Target was to get the form input and email it. Here I'm going to test only the DjangoEmail module using shell.
Edit settings.py with code below:
    #settings for django email( writing for gmail)
    EMAIL_USE_TLS = True
    EMAIL_HOST = 'smtp.gmail.com'
    SITE_HOST = '127.0.0.1:8000'
    DEFAULT_FROM_EMAIL ='Dotorbit Team '
    EMAIL_PORT = 587
    EMAIL_HOST_USER = 'dotorbit.dev@gmail.com'
    EMAIL_HOST_PASSWORD = 'your-password'
    #Run interactive mode, 
    python manage.py shell
    #Import the EmailMessage module,
    >>>from django.core.mail import EmailMessage
    #Send the email,
    >>>email = EmailMessage('Subject goes here ', ' Body goes here ', to=['reciever@email.com'])
    >>>email.send()
    >>>1

This will return 1, means everything is working fine. form and view, I'll write in next post.

Configure LAMP and How to fixing Apache issue ServerName issue.

Leave a Comment

There are lots of tutorials available for Apache,MySql and PHP installation on linux and Windows. But I prefer the simple one for Debian.Command will not work without caret(^). sudo apt-get install lamp-server^ Now,This will download and install the Apache,PHP and MySql. step1 : test "localhost" in browser. Works !!
step2 : run the apache2 service. $ sudo service apache2 restart
or
$ sudo /etc/init.d/apache2 restart
If it works !! You are champ.
For me ,It throws an error --
codeleaf@dotorbit-backbox:/media/Development/Developer/HEROKU/DotOrbit$ sudo service apache2 restart
* Restarting web server apache2
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
I googled about it and found the solution,
By default "httpd.conf" file will be blank. Now, simply add the following line to the file. $ sudo gedit /etc/apache2/httpd.conf Add the following line to "httpd.conf" and save it . ServerName localhost Now restart the server. $ sudo service apache2 restart
$ * Restarting web apache 2 server
... waiting
Woohoo.. It works
step3 - Test whether PHP is working or not ? Create "test.php" in /var/www/ directory. $ sudo gedit /var/www/test.php and add following line " < ?php phpinfo(); ? > step 4 - Test localhost/test.php and you will get the info page. e.g "PHP Version 5.3.10-1ubuntu3.4"

How to install 686-PAE kernel on Linux Mint Debian Edition-i486?

2 comments

Before using Linux Mint Debiab Edition(LMDE) I was using Ubuntu-12.04LTS .
It was my worst experience with ubuntu. It looks like Ubuntu12.04LTS is not matured. I've faced lots of problems like touchpad freezes , after updates system get crashed , lots of bug reporting etc . Anyway I'm not anti-ubuntu .
In frustration I removed Ubuntu12.04 and installed LMDE on my Dell Vostro-1540 (core-i3).
Since the kernel is built with LMDE 201 109 486, then the default kernel is only able to detect a single core . Result was ,I've experienced some sort have 'hang' during my Android application development .
I decided to install the kernel 686, exactly 686-PAE. This kernel is the best solution for running LMDE on 'multi-core' system .
No need to worry about it .
Simple steps are here to install linux-kernel-i686.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-686 linux-headers-686-pae
for i486.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-486 linux-headers-486
for amd64.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-amd64 linux-headers-amd64
