Opa is an open source, simple and unified platform for writing web applications. All aspects are directly written in Opa: Frontend code, backend code, database queries and configuration. And everything is strongly statically typed.

Node-Qt provides native bindings to the Qt library as a Node.js addon. The focus is on graphics and audio bindings; there is no need to duplicate the functionality of the Node API and its modules.

This is an introductory book to programming and computer science using assembly language. It assumes the reader has never programmed before, and introduces the concepts of variables, functions, and flow control. The reason for using assembly language is to get the reader thinking in terms of how the computer actually works underneath. Knowing how the computer works from a "bare-metal" standpoint is often the difference between top-level programmers and programmers who can never quite master their art.

Ren'Py is a visual novel engine that helps you use words, images, and sounds to tell stories with the computer. These can be both visual novels and life simulation games. The easy to learn script language allows you to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.

Ren'Py is open source and free for commercial use. It supports Windows, Mac OS X, Linux, and Android.

pandas is an open source, BSD-licensed library providing high-performance, easy-to-use data structures and data analysis tools for the Python programming language.

Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.

There are three books that I believe that every self-taught computer scientist should read. These are books that I often recommend to smart junior developers that learned their knowledge by doing instead of schooling. These are books that will close the gap for people that fall into the category of "or equivalent experience" on a job posting.

That can’t happen.


That doesn’t happen on my machine.


That shouldn’t happen.


Why does that happen?


Oh, I see.


How did that ever work?

PyPedia is a collaborative programming web environment. Each article in this wiki is a function or class or any other piece of Python code. No need to import anything. Just call the function or instantiate the class that belongs to any other article.

This guide is the culmination of a few months' worth of blog posts. The subject is magic methods.

What are magic methods? They're everything in object-oriented Python. They're special methods that you can define to add "magic" to your classes. They're always surrounded by double underscores (e.g. __init__ or __lt__). They're also not as well documented as they need to be. All of the magic methods for Python appear in the same section in the Python docs, but they're scattered about and only loosely organized. There's hardly an example to be found in that section (and that may very well be by design, since they're all detailed in the language reference, along with boring syntax descriptions, etc.).

So, to fix what I perceived as a flaw in Python's documentation, I set out to provide some more plain-English, example-driven documentation for Python's magic methods. I started out with weekly blog posts, and now that I've finished with those, I've put together this guide.

I hope you enjoy it. Use it as a tutorial, a refresher, or a reference; it's just intended to be a user-friendly guide to Python's magic methods.

A look into what goes into the area of preventing reverse engineering, and gives developers some functions and ideas about preventing reversing engineering of their programs.

Below are audio, video and lecture sides for 1997 and 2007. Since the lectures are 10 years apart some of the topics covered by the course have changed. The 1997 lectures have a better quality video and audio than the 2007, although the 2007 covers the newer material and has better lecture notes.

Hi there! LÖVE is an *awesome* framework you can use to make 2D games in Lua. It's free, open-source, and works on Windows, Mac OS X and Linux.

Flake8 is a wrapper around these tools:
PyFlakes
pep8
Ned's MacCabe script

Flake8 runs all tools by launching the single 'flake8' script, but ignores pep8 and PyFlakes extended options and just uses defaults. It displays the warnings in a per-file, merged output.

Game developers often experience a horrific "crunch" (also known as a "death march"), which happens in the last few months of a project leading up to the game's release date. Failing to meet the deadline can often mean the project gets cancelled or even worse, you lose your job. So what sort of tricks do they use while they're under the pump, doing 12+ hour per day for weeks on end?

Below are some classic anecdotes and tips

Tcl was, for many years, my go-to language of choice. It's still near and dear to me in many ways, and I even worked on a portion of a book about it ( http://journal.dedasys.com/2009/09/15/tcl-and-the-tk-toolkit-2nd-edition ).

However, examining what "went wrong" is quite interesting, if one attempts, as much as possible, a dispassionate, analytical approach that aims to gain knowledge, rather than assign blame or paper over real defects with a rose-colored vision of things. It has made me consider, and learn, about a variety of aspects of the software industry, such as economics and marketing, that I had not previously been interested in. Indeed, my thesis is that Tcl and Tk's problems primarily stem from economic and marketing (human) factors, rather than any serious defects with the technology itself.

Context Free is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.

Tinycon allows the addition of alert bubbles and changing the favicon image. Tinycon gracefully falls back to a number in title approach for browsers that don't support canvas or dynamic favicons.

Alerts in the favicon allow users to pin a tab and easily see if their attention is needed.

A Programming Primer for Counting and Other Unconventional Tasks

This set of tutorials aims to take you through programming a simple UNIX-clone operating system for the x86 architecture. The tutorial uses C as the language of choice, with liberally mixed in bits of assembler. The aim is to talk you through the design and implementation decisions in making an operating system. The OS we make is monolithic in design (drivers are loaded through kernel-mode modules as opposed to user-mode programs), as this is simpler.

DStruct lets you properly encapsulate your simple value objects so your interfaces are extensible from day one, plus add schema enforcement to catch data problems at object initialization time. Encapsulate, encapsulate, encapsulate!

furl is a small Python library that makes manipulating URLs simple.

Python's standard urllib and urlparse modules provide a number of URL manipulation functions, but using these functions to perform common URL manipulations proves tedious. Furl makes manipulating URLs simple.

Muntjac is a translation of Vaadin to the Python programming language. It is similar to GUI toolkits for desktop applications, such as PyQT, wxPython and PyGTK. However, it can be used to create dynamic, browser independent, web applications. There is no need to write HTML, Javascript or RPC code, just server-side Python.

Cinder is a community-developed, free and open source library for professional-quality creative coding in C++

Software is a cornerstone of science. Without software, twenty-first century science would be impossible. Without better software, science cannot progress.

But the culture and institutions of science have not yet adjusted to this reality. We need to reform them to address this challenge, by adopting these five principles:
Code
All source code written specifically to process data for a published paper must be available to the reviewers and readers of the paper.
Copyright
The copyright ownership and license of any released source code must be clearly stated.
Citation
Researchers who use or adapt science source code in their research must credit the code’s creators in resulting publications.
Credit
Software contributions must be included in systems of scientific assessment, credit, and recognition.
Curation
Source code must remain available, linked to related materials, for the useful lifetime of the publication.

Put the internet to work for you by creating tasks that fit this simple structure:
