In review of a project today, I realize I need to write down some general rules on memory management around Objective-C. I'm going to write more on this but here are some general rules: Case 1. Setting properties. Obj *obj = [[obj alloc] init]; myClient.obj = obj; [obj

Since I started training my staffs on iPhone development, I thought may be it's time to restart my teaching profession (I built a Java training school back in 2002). So we will start offering a 3-day crash course on everything iPhone soon. Here is the description: ========================================================= PD401

One of my team member told me that she saw another team using our J-RAT method. I said "Great! How they like it." "All developers hated it," she said. "They didn't like being watched and couldn't actually code when sitting

My computer life began when my mom got me an Apple IIe in the 80s. I had great fun with that machine. Coding in Basic, upgrading memory (got the great 128K memory card) and even upgrading the CPU and built-in ROM. I left Apple when I sold the IIe
