I was back at work last night writing code to handle special cases in the linkage simulator. It turns out that every type of connection is a special case, almost. Here is what I have working: There is one case I can see that is missing but the…
Continue readingI have a programming problem at work and a possible solution. The only thing wrong with the solution is that it is too big. “Too big” will make sense once I’ve described the problem and the solution. The solution comes from the book Modern C++ Design by Andrei…
Continue readingI thought I might write down some points about how the simulator works for future reference and to help me think about it and make improvements. The linkage program is a bit experimental so I try to get something working and then worry about making it better later….
Continue readingThis is another special case. It seems like the sliding connectors have many special cases. I thought that there were three but now, with this one, there are four. The good news is that I have the two more normal cases working. They are the cases where there…
Continue readingI did some work on the linkage simulator last night. I think I’ve narrowed down the sliding connector issue in the linkage program. There are essentially three situations I need to handle. Consider these images: Figure 1. In figure 1, A and E are fixed. F will be…
Continue readingI wrote a small PHP script last night to do image processing. I was surprised that it works. I needed to accept a file name, rotation angle, and color. The script opens the PNG file, enlarges it a few pixels to ensure that the rotation doesn’t cause edge…

The program usually runs a few minutes with optimizations, etc…,…
