  What Can We Learn From Dennis Ritchie?

As we noted earlier this week, one of the founding fathers of UNIX and the creator of C, Dennis Ritchie, passed away last weekend. While I feel that many in computer science and related fields knew of Ritchie’s importance to the growth and development of, well, everything to do with computing, I think it’s valuable to look back at his accomplishments and place him high in the CS pantheon already populated by Lovelace, Turing, and (although this crowing will be controversial, at lea...

  Why I Hate Android

Why do I hate Android? It’s definitely one of the questions I get asked most often these days. And most of those that don’t ask probably assume it’s because I’m an iPhone guy. People see negative take after negative take about the operating system and label me as “unreasonable” or “biased” or worse. I should probably explain.

  Understanding lvalues and rvalues in C and C++

The terms lvalue and rvalue are not something one runs into often in C/C++ programming, but when one does, it’s usually not immediately clear what they mean. The most common place to run into these terms are in compiler error & warning messages. For example, compiling the following with gcc: int foo() {return 2;} int main() { foo() = 2; return 0; } You get: test.c: In function 'main': test.c:8:5: error: lvalue required as left operand of assignment True, this code ...

  PHP: a fractal of bad design

Preface I’m cranky. I complain about a lot of things.
