Online Python Tutor - Learn programming by visualizing code execution
Online Python Tutor is a free educational tool created by Philip Guo that helps students overcome a fundamental barrier to learning programming: understanding what happens as the computer executes each line of a program's source code. Using this tool, a teacher or student can write a Python program in the Web browser and visualize what the computer is doing step-by-step as it executes the program. As of Dec 2013, over 500,000 people in over 165 countries have used Online Python Tutor to understand and debug their programs, often as a supplement to textbooks, lecture notes, and online programming tutorials. Over 6,000 pieces of Python code are executed and visualized every day. Users include self-directed learners, students taking online courses from Coursera, edX, and Udacity, and professors in dozens of universities such as MIT, UC Berkeley, and the University of Washington. You can also visualize execution in the IPython shell in interactive mode.

You have stumbled upon the class handouts for a course I taught at Lawrence Livermore National Lab, June 12-June 14, 2007. These notes are intended to accompany my lecture, which was a demonstration of a variety of "intermediate" Python features and packages.

I realized this when I started looking for learning resources for simple hacking people do. Even to start doing the simplest hack on own, a hacker requires to have in depth knowledge of multiple topics.

The “Invent with Python” Blog I've written an article for called APIs, not apps: What the future will be like when everyone can code, where I write about a coming future where programming ability is in the hands of everyone. Excerpt: Despite this hype, I do think that coding will become a more widespread and routine skill in the years to come. Programmable technology will continue to pervade more parts of our life, computers will continue to become more accessible to a wider population, and the world will continue to become more complex. Teach Coding in the Classroom: Resources from ISTE '14 I was super excited to attend Hack Education (originally called “EdubloggerCon”), an all-day unconference held the Friday before the formal start of ISTE 2014. This interactive day of learning, now in its eighth year, was touted to me as the event to attend in Atlanta, and it did not disappoint. The informal, small-group conversations were inclusive and welcoming. The "rule of two feet" meant that if you needed to move, you were encouraged.

Codematician Getting to know Python is a pretty hairy task, as is diving into any language. Fortunately Python is considered an easy language to learn and the potential for using it in HPC settings is pretty large. Below I give an introduction to learning, speeding, and scaling Python. Free Programming, SQL Data Coding, Computer Science. IT Books PHP Reference: Beginner to Intermediate PHP 5 PHP programmers need of a quick reference book. Beginner and intermediate PHP coders with some experience in PHP, includes code using procedural PHP and standard syntax. Book covers areas of mail handling, file manipulation, regular expressions, MySQL sessions, and cookies.

Mathematics, philosophy, code, travel and everything in between. Google App Engine is a pretty interesting PaaS offering. However, its Python environment leaves a lot to be desired. The biggest pain point is its seeming incompatibility with virtualenv – a tool that is almost indispensable in Python development. Luckily, there is a workaround. Virtual environments are perfect for isolating your project from the global Python installation and managing its package dependencies separately. Unfortunately, most App Engine guides will tell you to “just download package ZIPs and unpack them in your project directory.” Stop Making Sprites (Compass, Sass, and PNG Sprite Generation) Update 01/11/12: new code at the bottom of this post. Sass has been kicking around for a while, but I hadn’t given it a try until just recently. Sass usually goes hand-in-hand with Rails, Compass makes it so easy to run Sass on standalone projects that I’ve started using it on nearly everything.
