What OO Fails to Do What object oriented programming fails to do is express collaborations between objects. To show you exactly what I mean, let’s take a look at two system operations (two use cases) requiring the same group of objects collaborating with each other. (…) DCI to the Rescue DCI is a paradigm invented by Trygve Reenskaug (the inventor of the MVC pattern) to solve these problems. (via Data Context Interaction: The Evolution of the Object Oriented Paradigm – SitePoint ) ...

Ruby Conf 12 – Y Not: Adventures in Functional Programming by Jim Weirich (by Confreaks) One of the deepest mysteries in the functional programming world is the Y-Combinator. Many have heard of it, but few have mastered its mysteries. Although fairly useless in real world software, understanding how the Y-Combinator works and why it is important gives the student an important insight into the nature of functional programming.
A programmer takes between 10-15 minutes to start editing code after resuming work from an interruption. When interrupted during an edit of a method, only 10% of times did a programmer resume work in less than a minute. A programmer is likely to get just one uninterrupted 2-hour session in a day (via Programmer Interrupted )

Zach Waugh: Preventing Xcode from building with #error zachwaugh: (…) I wanted Xcode to not even build the app if conflicting conditions were enabled. I came across the #error preprocessor directive which does exactly that, and can be used like this: #if defined(APP_STORE) && defined(BETA) #error Beta enabled for App Store build! #endif

We had made plans to meet at a nice restaurant for dinner. I was shopping with my friends all day long, so I thought he was upset at the fact that I was a bit late, but he made no comment on it. Conversation wasn’t flowing, so I suggested that we go somewhere quiet so we could talk. He agreed, but he didn’t say much. I asked him what was wrong; He said, ‘Nothing’. I asked him if it was my fault that he was upset. He said he wasn’t upset, that it had nothing to do with me, and not to worry about it. On the way home, I told him that I loved him. He smiled slightly, and kept driving. I can’t explain his behavior I don’t know why he didn’t say, ‘I love you, too.’ When we got home, I felt as if I had lost him completely, as if he wanted nothing to do with me anymore. He just sat there quietly, and watched TV. He continued to seem distant and absent. Finally, with silence all around us, I decided to go to bed. About 15 minutes later, he came to bed. But I still felt that he was distracted, and his thoughts were somewhere else. He fell asleep – I cried. I don’t know what to do. I’m almost sure that his thoughts are with someone else. My life is a disaster. ...

What Every Computer Scientist Should Know About Floating-Point Arithmetic Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every operating system must respond to floating-point exceptions such as overflow. This paper presents a tutorial on those aspects of floating-point that have a direct impact on designers of computer systems. It begins with background on floating-point representation and rounding error, continues with a discussion of the IEEE floating-point standard, and concludes with numerous examples of how computer builders can better support floating-point. ...

Learnable Programming Programming is a way of thinking, not a rote skill. Learning about “for” loops is not learning to program, any more than learning about pencils is learning to draw. People understand what they can see. If a programmer cannot see what a program is doing, she can’t understand it. Excellent essay about programming “without blindfolds”.
