Blog Entries publications that: entertain, make you think, offer insight
The short answer is, yes and no. It depends upon who you are. The purpose of this entry is to help you determine, yes or no.
Full disclosure. This entry is created on a Mac mini. And doing so on Windows 8 (Release Preview). If you are a developer, in my humble opinion you need to test on all platforms you expect your app to run or you are not much of a developer.
To be successful you need to leave politics in geographical territory known as Washington DC. My definition of that is: 14 mi.² of real estate surrounded by reality.
Only in politics can we afford to take sides. Those of us in IT, especially developers need to do our best to be all things to all people. Certainly this is a technical impossibility. However in our game we can get some points for at least being serviceable if not outstanding.
Before we go to the list do you know what makes software skills most sought-after and hence more valuable than most of the other job skills? It is simply because unlike any other skill, software skills are global and are not at all location specific! With the evolution and penetration of internet technologies, the physical distance between the client and service provider hardly matters. So, with more advancement in technology, it is indeed going to rain opportunities on the right skilled developer. I’ll take the liberty to reproduce the following quotes here to prove my claims statistically:
Demand for “cloud-ready” IT workers will grow by 26 percent annually through 2015, with as many as 7 million cloud-related jobs available worldwide.
---IDC White Paper (November 2012).
In the United States, the IT sector is experiencing modest growth of IT jobs in general, with the average growth in IT employment between 1.1 and 2.7 percent per year through 2020.
---U.S. Bureau of Labor Statistics.

Creating an enum in Python prior to Python 3.4 was accomplished as follows:
def enum(**enums)::
return type('Enum',(),enums)
then use as:
Animals=enum(Dog=1,Cat=2)
and accessed as:
Animals.Dog
The new version can be created as follows:
from enum import Enum
class Animal(Enum):
Dog=1
Cat=2
