Braindump: programming vs. scripting

What is the difference between a program and a script? Imagine a scale, at one end is a cake recipe and at the other end is a rich set of objects or functions glued together to perform something cool. Move along the scale a bit from cake recipe until you get to a set of instructions that can be understood by a computer. This is then a script. A set of thing to be done to achieve a result. Simple unit testing is driven by a script. It has repititions and is not refactored or normalised. Of course we can embelish our script with more features of our language, but then it moves along the scale towards the "real" programs. Actually, a script is already a program - just a very simplistic program. The scale is more a sort of scale of language feature implementation. The left side is our script, which could be just a set of calls to other programs. The right side is where we implement everything in the scope of our program. So we can write in a scripting style in C++ and write a program in Perl.

Python conditions with None and empty string

In Python I want to test if a variable is None or if it is an empty string. This might look like this:

if (var is None) or (var == ""): do_something()

This can be somewhat simplified as Python None and "" evaluate to False in a boolean expression:

if not var: do_something()

#python #none #if

#calculus #beginners

Spirit (Geist)

So where Hegel talks about spirit, is it OK if I substitute this for meme?

#Hegel #spirit #Geist #Dawkins #meme

#schlangenbad #snake #bath #tree

Don’t forget that powershell uses -eq and not = Especially when you are playing with firewall objects. Otherwise you might be glad you took a snapshot.

Create a github repo

# curl -u USER https://api.github.com/user/repos -d '{"name":"REPO"}'

where USER is your uid and REPO is the name of the repository you want to create.

# git remote add RP https://github.com/USER/REPO

# git push RP master

#git #github #repository

This video presents the fundamental concepts for relation tables and using the normalization design process to minimize structural problems with the tables you design in relational databases. The presentation first covers the fundamental concepts and design process, and then walks you through an exercise showing how the normalization rules are applied.

In 1989 the American musicologist Alan W. Pollack started to analyze the songs of the Beatles. He published his first results on internet. In 1991 after he had finished the work on 28 songs he bravely decided to do the whole lot of them. About ten years later, in 2000 he completed the analysis of the official Beatles' canon, consisting of 187 songs and 25 covers. Here we have ordered this massive work in five categories. And, for your convenience, we've added some indices as well as a short introduction.
