Let's Reconsider That A Set of Unit Testing Rules by Michael Feathers September 9, 2005 Teams that adopt agile practices often adopt Test Driven Development (TDD), which means, of course, that they end up writing a lot of tests. In general, that�s great but there is a failure case for teams that attempt to get test infected; you can end up writing very slow tests that take so long to run that they

The much anticipated third edition of Programming in Scala is now available! This book is the authoritative tutorial on the Scala programming language, co-written by the language's designer Martin Odersky. The Scala language, which blends object-oriented and functional programming concepts, has been exploding in popularity in recent years. This book is a comprehensive, step-by-step guide to learni

Martin Odersky talks with Bill Venners about the history that led to the creation of the Scala programming language. Scala, a general-purpose, object-oriented, functional language for the JVM, is the brainchild of Martin Odersky, a professor at Ecole Polytechnique Fédérale de Lausanne (EPFL). In the first part of a multi-part interview series, Martin Odersky discusses Scala's history and origins w

Scala Puzzlers The fun path to deeper understanding by Andrew Phillips and Nermin Šerifović Getting code to do what we want it to do is perhaps the essence of our purpose as developers. So there are few things more intriguing or important than code that we think we understand, but that behaves rather contrary to our expectations. Scala Puzzlers is a collection of such examples in Scala. It is not

This book is the authoritative tutorial on the Scala programming language, co-written by the language's designer, Martin Odersky. This fifth edition has been updated to cover new features up to and including Scala version 3.0.

The compiletime project is an attempt to better understand the relationship between the use of Scala's features and compile time. This article gives a quick overview of what we've learned so far. Long build times is a common complaint among Scala users. As the author of ScalaTest, I have been concerned about both the compile and run time of tests, since this often accounts for a significant portio

In this article you will learn how to get started building web applications with Play 2, Scala, Squeryl, JSON, CoffeeScript, and jQuery. You will also learn how to test the application with ScalaTest and then deploy the application on the cloud with Heroku. The combination of Play 2, Scala, Squeryl, JSON, CoffeeScript, jQuery, and ScalaTest provides a very efficient way to build and test modern we

Computing Thoughts Web App with jQuery, CoffeeScript, Ajax, Web.py & Heroku by Bruce Eckel September 30, 2011 Summary Following up on my previous article, I create a super-simple example where a web page communicates with the server (written in Web.py) sending a JSON request object and receiving a JSON object as a response, which it uses to dynamically update the page. Afterwards, James Ward quick

Heron-Centric: Ruminations of a Language Designer The Principles of Good Programming by Christopher Diggins July 24, 2011 Summary Over the years I have found that following a relatively small number of fundamental guiding principles has helped me become a much more effective programmer. Today's post is a lightly edited repost from my blog at The Area, a web-site dedicated to users of Autodesk medi

Computing Thoughts JavaScript Redux (and Closures) by Bruce Eckel July 15, 2011 Summary It appears we are stuck with JavaScript, at least in the near-to-mid term. Although the language is an abomination, some things are getting better. I discovered a couple of great lectures and a book that might change your perspective (a little) about the language. In addition, if you still don't understand clos

Computing Thoughts Scala: The Static Language that Feels Dynamic by Bruce Eckel June 12, 2011 Summary The highest complement you can deliver in the Python world is to say that something is "Pythonic" -- that it feels and fits into the Python way of thinking. I never imagined that a static language could feel this way, but Scala does -- and possibly even better. I'm actually glad I waited this long

Cool Tools and Other Stuff JavaOne 2010: Functional Programming, from Java to Scala by Eric Armstrong September 23, 2010 Summary Dick Wall's talk turns out to be a treasure trove of useful tidbits, and a great introduction to Scala that whets my appetite, big time. Dick Wall's talk was a revelation. The title was "Funky Java, Objective Scala". It sounded intriguing, but I didn't really know what t

James Gosling talks with Bill Venners about how to build solid apps, organize your catch clauses, scale checked exceptions, and deal with failure. Much has been written recently about the value that checked exceptions add, or subtract, from Java. Some programmers feel that checked exceptions help them build robust applications. Others find that checked exceptions are an annoyance that hinders thei

Object-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system action. DCI is a vision to capture the end user cognitive model of roles and interactions between them. Objects are principally about people and their mental mode

Angle Brackets and Curly Braces ScalaTest Matchers Preview by Bill Venners December 31, 2008 Summary The next version of ScalaTest will include a set of matchers.

Interested in Flex graphics? Check out the new book Flex 4 Fun by Chet Haase, available as a PrePrint™ from Artima Press. A key concept in object-oriented programming centers around an object encapsulating some state, and then notifying other interested objects when that internal state changes. User interfaces represent some of the best examples of stateful object-oriented design in part because i

A Taste of Scala The Autoproxy Plugin - Part I by Kevin Wright November 26, 2009 Code Considered Harmful A recent post on the Scala mailing lists stated that (as a rule of thumb) one in every ten lines of freshly written code contains a defect. The "industry standard" is somewhere closer to 15-50 defects for every 1000 lines of code in production. Between being written and released, code passes th
