  Yes, Virginia, Scala is hard

Let me first say that I am a Scala lover and have been a Scala champion for almost 5 years.  I've written books and articles on Scala.  I've worked with dozens of companies that have launched Scala and Lift projects.  I've code reviewed many dozens of Scala projects.I used to think that Scala was easy.  It was, and continues to be, a cure for some of the numerous problems with Java.  From the "stuff that's hard or impossible in Java is simple in Scala," Scala is a very e...

  CSS3 Animation With jQuery Fallbacks

In today's post, we'll be taking a look at how you can use CSS3 transitions to power your application's animations with jQuery's .animate() method as a fallback where transitions aren't supported. The benefit of transitions is that unlike JavaScript based animations, they're hardware accelerated in certain browsers and mobile devices, resulting in a potentially smoother overall animation than you would normally experience. In a lot of cases your code will work seamlessly with the solut...

  Preprocessor magic:Default Arguments in C

This post is for programmers who like C or for one reason or another can't use anything else but C in one of their projects. The advantages of having default arguments is not something that needs convincing. It's just very nice and convenient to have them. C++ offers the ability to define them but C under the C99 standard has no way to allow it. In this post I will detail two ways I know of implementing default arguments in C. If a reader happens to know additional ways please share in ...

   Move.Me Writing Your Own WebSocket Server

The WebSocket protocol has applications beyond plain vanilla web development.  I will explain how the protocol works, how to implement your own server and share some insights I had along the way. Before we get down and dirty, I will explain what I’ve been doing with it. At this point I expect many of you are saying “I’m not working on a web game this doesn’t seem relevant to me.” Well, neither am I. I embed a WebSocket server into my game engine and wit...

  The 10 Greatest Hacks of My Life

My co-founder and I briefly considered applying to YCombinator for the Winter 2012 session. We eventually decided to bootstrap Curvio initially, and raise a seed round on our own after we launch (so far so good!). But looking over the YC application, one question intrigued me:Please tell us about the time you, tansey, most successfully hacked some (non-computer) system to your advantage.Now, there are a lot of ways to interpret this. A mechanical interpretation would be about...

  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  A re-introduction to JavaScript

Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

  Performance is a Feature

We've always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we're performance wonks (guilty!), but because we think speed is a competitive advantage. There's plenty of experimental data proving that the slower your website loads and displays, the less people will use it. [Google found that] the page with 10 results took 0.4 seconds to generate. The page with 30 results took 0.9 seconds. Half a second delay caused a 20% drop in traffic. Half a seco...

  Cross Browser HTML5 Drag and Drop

HTML5 Drag and Drop has been talked about a lot lately, but it’s hard to find really useful information about implementing it across multiple browsers.Mozilla, Apple and Microsoft all have pages describing how to use it, but their examples seem to work only in their particular browser (Apple’s example doesn’t even work in their own! Updated, Jan. 11, 2009: Although I have not been able to get this example working on Safari 2.0.4 and 3....

  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us have the slightest clue what we’re doing. Combine with Sturgeon’s Law, and I have a lifetime’s worth of stuff to gripe about. This is not the same. PHP is not merely awkward to use, or ill-suited for what I want, or suboptimal, or...
