The first podcast was Christopher Lydon’s Radio Open Source. The term podcast was created to describe it. It’s still going strong. If you like ideas, books, music, vaguely leftish politics you might like it.
It has nothing to do with open source software.
I used to work on a debugger. It was called TotalView, and it was a really stellar multiprocess, multithread debugger. You could debug programs with thousands of cores and threads. You could type real C++ code to inspect values, inject code into a running process, force the CPU to run at a given line, like a magic goto. But we had a saying “printf wins again”. Sometimes you just can’t get the debugger to tell you what you need.
