Things which I do after installing Crunchbang #! Linux.

December 24, 2014 0
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.

November 20, 2014 0
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.

June 26, 2014 0
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
