NSScreencast features weekly bite-sized screencasts on iOS development.

Frink is a practical calculating tool and programming language designed to make physical calculations simple, to help ensure that answers come out right, and to make a tool that's really useful in the real world. It tracks units of measure (feet, meters, kilograms, watts, etc.) through all calculations, allowing you to mix units of measure transparently, and helps you easily verify that your answers make sense. It also contains a large data file of physical quantities, freeing you from having to look them up, and freeing you to make effortless calculations without getting bogged down in the mechanics.

A set of open source tools that complement Xcode and Interface Builder. Interactive introspection, manipulation and scripting of Cocoa objects.

This guide isn’t about the powerful functinality VIM has over-and-above Textmate; you’ll figure this out with time. This guide is to help you do in VIM what you already can using Textmate, only with considerably less pain than I underwent.

Want to learn vim (the best text editor known to human kind) the fastest way possible. I suggest you a way. Start by learning the minimal to survive, then integrate slowly all tricks.

Crash into Python is a set of documents/slides that are meant to be used as a teaching aid for bringing programmers from other languages up to speed with Python. It assumes that you have enough familiarity with programming to know what function and class mean, and will recognize that print probably doesn't put ink on paper. More importantly, it assumes that you either have an instructor who is well-versed in Python, or are resourceful enough to find answers for yourself. A number of these slides are designed to trigger questions and discussion, so if it seems like you're missing something, that's a good sign you could be digging deeper.

AsyncSocket is an asynchronous socket networking library for Cocoa.

I won’t talk about any of the projects’ details, merely about the branching strategy and release management.

The site for the book "Learn Python The Hard Way". The book is a very beginner book for people who want to learn to code. If you can already code then the book will probably drive you insane. It's intended for people who have no coding chops to build up their skills before starting a more detailed book.

Yet Another JSON Library. YAJL is a small event-driven (SAX-style) JSON parser written in ANSI C, and a small validating JSON generator. YAJL is released under the BSD license.

Can we capture the unpredictable evolutionary and emergent properties of nature in software? Can understanding the mathematical principles behind our physical world world help us to create digital worlds? This class will focus on the programming strategies and techniques behind computer simulations of natural systems. We’ll explore topics ranging from basic mathematics and physics concepts to more advanced simulations of complex systems. Subjects covered will include forces, trigonometry, fractals, cellular automata, self-organization, and genetic algorithms. Examples will be demonstrated using Processing with a focus on object oriented programming.

Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience.

HMVC is a collection of traditional MVC triads operating as one application. Each triad is completely independent and can execute without the presence of any other. All requests made to triads must use the controller interface, never loading models or libraries outside of their own domain. The triads physical location within the hosting environment is not important, as long as it is accessible from all other parts of the system. The distinct features of HMVC encourages the reuse of existing code, simplifies testing of disparate parts of the system and ensures that the application is easily enhanced or extended.

Converts javascript command into no alnum version using only []()+! characters (unless you input extras).

The Objective-C Runtime is one of the overlooked features of Objective-C initially when people are generally introduced to Cocoa/Objective-C. The reason for this is that while Objective-C (the language) is easy to pick up in only a couple hours, newcomers to Cocoa spend most of their time wrapping their heads around the Cocoa Framework and adjusting to how it works.

In this roundup, we will review some online Integrated Development Environments (IDEs) which are great examples of cloud programming. These solutions can [nearly] replace your desktop IDEs and code editors.

TBXML is a light-weight XML document parser written in Objective-C designed for use on Apple iPhone / iPod Touch devices. TBXML aims to provide the fastest possible XML parsing whilst utilising the fewest resources. This requirement for absolute efficiency is achieved at the expence of XML validation and modification. It is NOT possible to modify and generate valid XML from a TBXML object and NO validation is performed whatsoever whilst importing and parsing an XML document.

So many applications have linear controls for volume. This is wrong. Ears do not perceive amplitude linearly.

A common programming problem: identify the URLs in an arbitrary string of text, where by “arbitrary” let’s agree we mean something unstructured such as an email message or a tweet.

It is very easy, when developing on a new operating system, to create projects that won't run on any previous OS version. To ensure backwards compatibility, there are Xcode and gcc options that allow you to build while maintaining support for earlier OS versions. In this post, I'll look at the ways in which this compatibility is controlled and some of the new ways it can go wrong on Snow Leopard.

There is no single-line method for converting between formatting date strings and date objects in Cocoa — the API opts for flexibility rather than simplicity. Unfortunately, this combines with documentation that omits, misdirects and occasionally misinforms, making NSDateFormatter one of the more confusing classes for new Cocoa programmers. In this post, I'll try to address some of the documentation issues and I'll present some methods that will turn NSDate into a formatted string or convert between date strings in a single method.

Many web sites allow users to provide feedback on products, services or other users. In addition to verbal reviews, rating facilities are typically present that allow visitors to rate an item from 0 to 5 (often in conjuction with stars), from 0 to 10, or simply by voting + or -, respectively. These visitor ratings are then often used to rank the rated items. And when “rank” comes into play, it gets tricky.

NimbleKit is the fastest way to create applications for iPhone and iPod touch. You don't need to know Objective-C or iPhone SDK. All you need is to know how to write an HTML page with Javascript code.

CoffeeScript is a little language that compiles into JavaScript. Think of it as JavaScript's less ostentatious kid brother — the same genes, roughly the same height, but a different sense of style. Apart from a handful of bonus goodies, statements in CoffeeScript correspond one-to-one with their equivalent in JavaScript, it's just another way of saying it.

Computer Science 50: Introduction to Computer Science I is a first course in computer science at Harvard College for concentrators and non-concentrators alike. More than just teach you how to program, this course teaches you how to think more methodically and how to solve problems more effectively. As such, its lessons are applicable well beyond the boundaries of computer science itself. That the course does teach you how to program, though, is perhaps its most empowering return. With this skill comes the ability to solve real-world problems in ways and at speeds beyond the abilities of most humans.
