I think you're right about all that, and that it's even worse than that. With what military would the new California defend itself? What would stop the United States-sans-California from immediately annexing California as a terri

This is interesting work! That said, it's a little disappointing when runtimes require custom algorithms or metadata to walk the stack and construct a stack trace. It makes it harder to build debuggers that grok the state of multiple

It's fine that the car is a work in progress and it's also fine that they'll be tested on the streets before being fully baked. What's not fine is insisting you don't need a permit (the primary purpose of which appe

There are several good points here -- particularly about the many reasons why poor code might have been written poorly, and the importance of not being smug about it. I don't think there's much value in blaming authors. But just

Ironically, C memory leaks are often significantly easier to debug than Java ones. In C, libraries like libumem basically do postmortem GC that can point straight to the leaking callstack (depending on how much debug info you can tolerate).

The claim that increased automation will enable people not to work is often cited as a defense of putting people out of work in favor of automation. This relies heavily on a number of assumptions that I think are empirically completely unt

It's very unfortunate that attempting to use preincrement and postincrement operators in Python results not in a syntax error, but in code that silently does something very unexpected.
