Architectural Questions

Are responsibilities well defined?
Are the collaborations well defined?
Is coupling minimized?
Can you identify potential duplication?
Are interface definitions and constraints acceptable?
Can modules access needed data—when needed?

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

	* @brief Mapping functions from Eigen data types to OpenCV
	* @author Eugene Khvedchenya <[email protected]>
	* @details This header file contains code snippet for easy mapping Eigen types to OpenCV and back with minimal overhead.
	* @more computer-vision.talks.com/articles/mapping-eigen-to-opencv/
	* Features:
	* - Mapping plain data types with no overhead (read/write access)
	* - Mapping expressions via evaluation (read only acess)
	*
	* Known issues:

	#include<stdio.h>
	#include<string.h>
	#include<stdlib.h>
	#include<sys/mman.h>
	typedef void V;typedef int I;typedef double F;typedef unsigned char C,*S;typedef long L;
	#define O printf
	#define R return
	#define I(a...) if(a)
	#define W(a...) while(a)

	# Type(<scope>): <subject>

	# <body>

	# <footer>

	# Type should be one of the following:
	# * feat (new feature)
	# * fix (bug fix)
	# * docs (changes to documentation)

	# How to encode and decode a file backed up as a series of printed QR codes

	# Install the required tools

	sudo apt-get update
	sudo apt-get install zbar-tools imagemagick qrencode
