Classic Programming Quotes. Best Programming Quotations. A good programmer is someone who looks both ways before crossing a one-way street. -- Doug Linder, systems administrator A most important, but also most elusive, aspect of any tool is its influence on the habits of those who train themselves in its use.
If the tool is a programming language this influence is, whether we like it or not, an influence on our thinking habits. -- Edsger Dijkstra, computer scientist Being abstract is something profoundly different from being vague... The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise. -- Edsger Dijkstra Besides a mathematical inclination, an exceptionally good mastery of one's native tongue is the most vital asset of a competent programmer. -- Edsger Dijkstra C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg. -- Bjarne Stroustrup, developer of the C++ programming language.

Mathematicians don't answer questions by working them out on paper the way schoolchildren are taught to. They do more in their heads: they try to understand a problem space well enough that they can walk around it the way you can walk around the memory of the house you grew up in. At its best programming is the same. You hold the whole program in your head, and you can manipulate it at will. That's particularly valuable at the start of a project, because initially the most important thing is to be able to change what you're doing. Your code is your understanding of the problem you're exploring. It's not easy to get a program into your head. Even the best programmers don't always have the whole program they're working on loaded into their heads. Python 101 : Blake O'Hare's School of Computer Science.
Here is the LiveStream page.
Lessons are broadcast live at 7PM PST every Friday and will be availble for on demand viewing afterwards. UPDATE: The first session was an utter disaster. I ran two practice sessions without a hitch, but this time the stream stopped several times and all data was lost except for one clip...a clip in the middle that would make no contextual sense by itself. I will now be posting non-live sessions using YouTube. I will also re-record what happened in this last session and re-post it as a series of youtube videos some time this weekend for those of you who missed all the technical difficulty shenanigans.
Pre-Lessons Lesson 1 Homework 1 Go to Project Euler and register an account. Solution Lesson 2 Lesson 3. Tutorial - Learn Python in 10 minutes. NOTE: If you would like some Python development done, my company, Stochastic Technologies, is available for consulting.
This tutorial is available as a short ebook. The e-book features extra content from follow-up posts on various Python best practices, all in a convenient, self-contained format. All future updates are free for people who purchase it. Preliminary fluff So, you want to learn the Python programming language but can't find a concise and yet full-featured tutorial. Properties Python is strongly typed (i.e. types are enforced), dynamically, implicitly typed (i.e. you don't have to declare variables), case sensitive (i.e. var and VAR are two different variables) and object-oriented (i.e. everything is an object). Getting help Help in Python is always available right in the interpreter. >>> help(5)Help on int object:(etc etc) >>> dir(5)['__abs__', '__add__', ...] >>> abs. Syntax Python has no mandatory statement termination characters and blocks are specified by indentation. Strings. Invent Your Own Computer Games with Python - Learn how to program with a...
