I Found A Purse Near Dairy Circle, Bangalore!

I was going to Dairy circle yesterday evening. Near to the bus stop  I  found  a purse. A lot of people were standing and passing by but no one noticed it. I just looked around to see if any one is searching for it. But no one was there. I checked the contents to see if any number or any information is available to call the owner of the purse.

Here are the contents of the purse:

1. Bus ticket from Chennai to Bangalore
2. A shop's visiting card
3. A hundred rupee note
4. An old ten rupee note
5. Some change.
6. 3 photos
7. A SIM card

There was number written on the purse. I tried to call that number but it was not reachable and the SIM card also not working.

How To Install Adobe Digital Editions On Ubuntu 14.04?

Few days back, I rented an e-book from Kinige, a retailer of telugu print & ebooks. I thought I could read that book immediately on their website. But they offered a .acsm & I had to install ADE(Adobe Digital Editions) to read that book. Since ADE is not available for Linux platform, I had to install wine first and then install ADE from it.

1. Installing Wine:

Wine  is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OSX, & BSD. The easiest way to install wine on Ubuntu 14.04 is from its PPA. Open the terminal and run these commands.
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine1.7 winetricks
You can check if wine is installed correctly by typing  wine --version 

2. Install ADE

Once you installed wine, you can easily install ADE. The current version is ADE 4.0 as of today(Oct 9th 2014). But only ADE 1.7 works on wine. So you have to download ADE 1.7. You can download it from here. Once you have downloaded that, you can just double click and install it just like windows.

Use Space As Both Space & Control - Avoid Emacs Pinky!

Most of the  commands  in  Emacs start with  'Control'  &  'Meta'. Control key is present at the corners of the keyboard and its very uncomfortable to press it every-time to invoke a command. Most popular solution to this is to swap CAPS lock & CTRL key. But you have to press the key with Pinky which might cause Emacs Pinky.

A much better solution is to use space bar as control key. When you press the space bar, it will function as a normal space key. If you press it with any other key. it will function as control key. So, to run any commands, you can hold space with one thumb and press other key(s) with another hand which will be handy.

In Linux, you can achieve this with Space2Ctrl.

Install the dependencies, clone the repo, make and start the script.

sudo apt-get install libx11-dev libxtst-dev

git clone https://github.com/r0adrunner/Space2Ctrl

cd Space2Ctrl


./s2cctl start
Now you can use your space as space and control key.

Automatically Remove Unused Imports & Variables From Python

Unused code will distract you(and other people) while reading code. Also, a single unused import can cause out of memory error. So, it is considered as a bad practice. Lets try to get rid of unused imports & variables from Python code.

Autoflake removes unused imports and unused variables as reported by pyflakes. Install it
pip install --upgrade autoflake    

Now select a file which you want to clean and run this in terminal
autoflake --in-place --remove-unused-variables example.py
It removes all unused imports & variables from the file.

Instead of running this command every time, I wrote a simple elisp function and assigned a F8 key to that function. So while writing the code itself it can clean it & it's much efficient.

;; Py-rm - Remove unused variables & imports from python

(defun pyrm ()


  (setq command (concatenate 'string "autoflake --in-place --remove-unused-variables " buffer-file-name))

  (shell-command command)

  ;; Reload the modified file

  (revert-buffer t t)


;; set a custom key for pyrm

(global-set-key [f8] 'pyrm)

Put the above code in your emacs configuration file, restart it & press F8 whenever you want to clean the code.

However, if you just need to highlight but not delete them, you can install flymake and then enter this.
M-x flymake-mode RET 
It just highlights the other syntax errors and unused imports but won't delete them.

How To Get Telugu Books If You Are Out Of Andhra!

If you are a (Telugu) book worm and you are living out of Andhra, then getting Telugu books is a huge problem. Thankfully a lot of online stores are coming forward to solve this problem. Lets look at a few sites where we can get Telugu print & e-books.

1. Digital Library of India: [Free]

Government of India is spending a crazy amounts of money to digitize public domain books. This is the best place to get telugu ebooks for free of cost. Currently there are 23,370 books in Telugu. Eventhough you won't new books there, you can find a lot of great classics.

2. Kinige:

This is the most popular site(Alexa Traffic Rank: 118,798) for buying Telugu books online. They supply both print books & e-books. The good thing about Kinige is they rent the for a period of 30 days at a reduced price. Most books are available here and is a good place to get started.

3. Logili

One more popular (Alexa Traffic Rank: 138,459) website to buy books online. It's also has great collection. However they sell only print books but no e-books. At times when there are no print books on Kinige, this is a great alternative.

4. Flipkart:

Most of you heard of Flipkart. You can't get all telugu books here but a few. If you are a regular shopper at flipkart, you might get available books at discount price.

5. Amazon:

It is struggling & competing with other online stores in India. Here also you can find a reasonable number of telugu books are great discounts.

You can also buy telugu books at Supatha, BooksForYou, InfiBeam, EveningHour.

In addition to these sites, authors or publication houses might be running their own sites ( for example Yandamoori sells his books from his site also ), you can buy from them also.


Recently I came across AVKF. It also has a great collection of telugu books.

How To Fix Washedout Colors In VLC Media Player?

To get rid of this problem, just open preferences from the Tools menu. Uncheck "Accelerated video output" from the video settings.

 If you are using and old version of VLC, you might have an option to "Skip frames", you can select that option. Save your preferences and restart the VLC player. Now you can enjoy your videos. If the problem still persists make sure you have installed all your video drivers.

Django Meetup In Bangalore

"Krace played a key role in bringing back the almost dead Bangalore Python Users Group into action."
- Shreyansh Singhal on YourStory.

Few weeks back, while I was searching for Python I came across Krace's blog. Then I checked his Github, Stackoverflow, Quora profiles and I was amazed.

Last week when I found there was a Django users workshop by him & his friends, without a second thought I decided to go.

Since the organizers marked the location (ThoughtWorks Technologies) on Google Maps, its quite easy to reach there w/o any trouble.

Workshop took place from 10 A.M. to 5 P.M. The goal was to build a simple phone book app to add/view/edit contacts with Django & SQLite.

Before starting of workshop, organizers helped with installation of requirements(Django & South).

Krace showed the agenda. At each & every step, he first explained what he is going to do. Then he would do it and gives us time to complete the task. All organizers patiently helped in troubleshooting the errors at each and every step. In the end we had little Q & A session.

Overall it was a great hands on experience with great content & crew! Looking forward for more meetups!! Thank You very much!!!

If you are form Bangalore & love Python, don't miss Django & BangPypers meetup.

P.S: A snap of workshop..
