Wizard Book n. Hal Abelson's, Jerry Sussman's and Julie Sussman's Structure and Interpretation of Computer Programs (MIT Press, 1984; ISBN 0-262-01077-1), an excellent computer science text used in introductory courses at MIT. So called because of the wizard on the jacket. One of the bibles of the LISP/Scheme world. Also, less commonly, known as the Purple Book. from The New Hacker's Dictionary, 2nd edition (MIT Press, 1993) This site is a companion to the influential computer-science text Structure and Interpretation of Computer Programs, by Abelson, Sussman, and Sussman.

Python Sourced[edit] And what defines a 'python activist' anyway? Blowing up Perl installations worldwide? Aho/Ullman Foundations of Computer Science This book has been taken out of print by W. H. Freeman. You are welcome to use it if you like. We believed in 1992 it was the way to introduce theory in Computer Science, and we believe that today. --- Al Aho and Jeff Ullman Eric S. Raymond's Home Page Welcome to my piece of the Web. I maintain quite a lot of open-source software, FAQs, and HTML documents, so this site is rather complex. It's mostly validated HTML and light on the graphics, though. You won't have to wait an eon for any of the pages to load. If the software and FAQs I maintain are valuable to you (and especially if my software makes you money) please leave me a tip.

That is, composition, pipelining, higher order functions. This one is different. It shows examples of imperative, unfunctional code that people write every day and translates these examples to a functional style. The first section of the article takes short, data transforming loops and translates them into functional maps and reduces. The second section takes longer loops, breaks them up into units and makes each unit functional.

Fix error handling first Created 6 February 2003, last updated 24 January 2007 Often when unexpected errors first occur, I've found problems in the way the error is handled. This isn't surprising: error handling code is often the least-exercised part of your system, so it's natural that there are bugs in it. It is important to fix the error handling problems first, then the original error. Sometimes there is a whole chaing of problems started by the original error condition, then compounded as layers of error handling code mis-handle the condition. Fix all the problems, backwards. Online Learning: A Bachelor's Level Computer Science Program Curriculum (Updated) Introduction [Update: See also the follow-up post to this piece, An Intensive Bachelor's Level Computer Science Curriculum Program.] A few months back we took an in-depth look at MIT’s free online Introduction to Computer Science course, and laid out a self-study time table to complete the class within four months, along with a companion post providing learning benchmarks to chart your progress. In the present article, I'll step back and take a much more broad look at com-sci course offerings available for free on the internet, in order to answer a deceptively straightforward question: is it possible to complete the equivalent of a college bachelor’s degree in computer science through college and university courses that are freely available online? And if so, how does one do so? The former question is more difficult to answer than it may at first appear.

10 Million hits a day with Wordpress using a $15 server [Update 2] – It seems W3 Total Cache support has been silently discontinued – it’s not been updated for over 12 months now, and has allegedly got some security issues. Because of this, I would recommend not installing W3 Total Cache as part of these instructions, everything else should run fine. [/Update] [Update] – I’ve tested this using the new Ubuntu 12.04 LTS Edition, and the settings all appear to work correctly without modification. IGNOU teams up with Nokia to offer - Online Best Latest IGNOU teams up with Nokia to offer Price Reviews Nokia and Indira Gandhi National Open University (IGNOU) have teamed up to offer users certifications programs in English, via Nokia’s Ovi Life Tools service. Initially, for the launch pilot, they will offer the Certificate Programme in Functional English (CFE) on Life Tools enabled Nokia handsets in Maharashtra, from January to June 2011. The pilot programme will entail the ability to fill in admission forms via Ovi Life Tools, apart from receiving study material & related support with IGNOU’s “study aid and reinforcer” on their mobile via SMS. After the necessary examinations, students will receive their certificates from IGNOU.

Functional programming R, at its heart, is a functional programming (FP) language. This means that it provides many tools for the creation and manipulation of functions. In particular, R has what’s known as first class functions. You can do anything with functions that you can do with vectors: you can assign them to variables, store them in lists, pass them as arguments to other functions, create them inside functions, and even return them as the result of a function. Stringification Created 9 December 2002, last updated 6 February 2003 One of the greatest features of modern programming environments is also the most humble: ubiquitous stringification. When I first worked in Java, I didn't think much about the java.lang.Object.toString method.

27 Ways to Learn to Program Online Whether you are looking to switch careers and become a full-time programmer, want to try to build a website or app on the side, or are just looking to round out your skill set, learning to code has certainly been something a lot of people have started to do lately. And while being a programmer might not be for everyone, there is a lot to be said about gaining a better, more educated view of how all those pixels get moved around all those screens. Before we delve into our list of learning resources sites, we wanted to share some advice from Marissa Louie, a self-taught product designer for Ness Computing. A former startup founder, Louie told TNW that the hardest part of being self-taught – whether it’s design, programming, or any other discipline is, “gathering the courage.
