I checked out this new POC app called Booktorious by August Lilleaas. It’s actually pretty neat in that it’s a 100% client side web application that reads EPUB books. So I jumped over to epubBooks and downloaded Through the Looking-Glass just to see how far down the rabbit hole I could go with this (sorry couldn’t resist). The book rendered perfectly and performance was decent considering the whole thing was being loaded at one time.

# Chapter 1: Driving Code Through Tests
# Chapter 2: Designing Beautiful APIS / Chapter 3: Mastering the Dynamic Toolkit
# Chapter 4: Text Processing and File Management
# Chapter 5: Functional Programming Techniques
# Chapter 6: When Things Go Wrong
# Chapter 7: Reducing Cultural Barriers

This book, originally published by Prentice Hall in 1996, was taken out of print in 2001 and the rights to the book were subsequently returned to me by Pearson (the successor company to Prentice Hall). I have decided to make it available online in HTML format, and at the same time I have corrected several errata which were present in the printed editions of the book. It’s perfectly possible that I might have missed some, or even introduced some brand-new ones, as part of the process of transforming the text into HTML. If you spot any mistakes, please let me know so I can correct the master copy, which can be found at http://www.it.bton.ac.uk/staff/je/adacraft/.

Downloadable copies are available as http://www.it.bton.ac.uk/staff/je/adacraft/bookhtml.zip (in zip format for Windows systems) or as http://www.it.bton.ac.uk/staff/je/adacraft/bookhtml.tar.gz (a gzipped tarball for Unix systems). Each distribution also includes the complete set of examples from the book, both for Windows (adacraft.zip) and for Unix (adacraft.tar.gz).

This wikibook aims to provide beginners with an introduction to programming Mac OS X with Cocoa, using Xcode, the free developer tools provided with the operating system. Some knowledge of another programming language, preferably C, is assumed. The main guide is aimed at users of Mac OS X 10.3 or 10.4, but programming techniques that can only be used with 10.4 are avoided until the end.

In general, this text is written to be followed in order from start to finish. As each topic develops, it builds on the code written previously to add complexity and functionality.

I anatomize a successful open-source project, fetchmail, that was run as a deliberate test of the surprising theories about software engineering suggested by the history of Linux. I discuss these theories in terms of two fundamentally different development styles, the ``cathedral'' model of most of the commercial world versus the ``bazaar'' model of the Linux world. I show that these models derive from opposing assumptions about the nature of the software-debugging task. I then make a sustained argument from the Linux experience for the proposition that ``Given enough eyeballs, all bugs are shallow'', suggest productive analogies with other self-correcting systems of selfish agents, and conclude with some exploration of the implications of this insight for the future of software.

This is the online home of the book “Mercurial: The Definitive Guide”. It was published in 2009 by O'Reilly Media.

Mercurial is a fast, lightweight source control management system designed for easy and efficient handling of very large distributed projects. My book tells you what it is, why you should care, and how you can use it effectively.

Eloquent JavaScript
An opinionated guide to programming
by Marijn Haverbeke

Eloquent JavaScript is a digital book providing a comprehensive introduction (tutorial) to the JavaScript programming language. Apart from a bookful of text, it contains plenty of example programs, and an environment to try them out and play with them.

The book is aimed at the beginning programmer ― people with prior programming experience might also get something out of it, but they should not read chapters 2 to 5 too closely, because most of the concepts discussed there will probably be nothing new to them. Do make sure you read the end of the first chapter, which has some essential information about the book itself.

The book is freely available, and may be used (as a whole or in parts) in any way you see fit, as long as I am credited as the original author.

A copy of the book for off-line reading can be downloaded as a zip file, and a more easily printable version can be found here.
