Instead of a Little Program today, I'm going to answer a Little Question. This is a common beginner question, but I figure I'll just spell it out right here for posterity. First of all, you probably noticed that you can't do this: That's because the is declared as a so-called free function, but member functions are not free. Neither are func...
A different kind of run-around.
A programmer on the GHI team reported that they were hitting an assertion failure using an internal library and asked for help debugging it. I didn't work on this internal library, but on the other hand I'm also not afraid to look inside and around.

And they all contain text like this: Note: We take great care to ensure that PowerToys work as they should, but they are not part of XYZ and are not supported b...
In the book Hello Kitty Takes a Trip, the title character travels to New York, Florida, Vermont, and Hawaii, in that order. Now, sure, the Traveling Salesman Problem is NP-hard, but you're not even trying.
