Channel 9 just posted a new interview with me about ISO C++0x, C++’s place in the modern world, and all things C++. As usual when talking to Herb, the conversation is all about C++ (well, we do talk about C# for a little while, but in the context of C++. Tune in…). Go native!

On yesterday’s thread, I just wrote in a comment: @Jon: Yes, C++ is complex and the complexity is largely because of C compatibility. So just as C++ ‘won’ in the 90s because of its own strengths plus its C compatibility, C++11 is being adopted because of its own strengths plus its C++98 compatibility.

I also rewrote this in C and called gettimeofday(2) directly: $ cat gettimeofdaybench.c. top(1) showed that only the Cassandra database was consuming CPU.

For example, if we have files A, B, and C, we would have three TCP connections. You see, because TCP is a much older protocol and not made for just loading web pages, it doesn’t know about A, B, or C. You might think that’s not a big problem, as we see there is no loss for resources A and C. For HTTP/1.1, Large preview ).

When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience. It shouldn’t take much C# code to make an app that monitors the root of all drives, using buffer sizes that start small and gradually get larger. You know where to find me.

Java/Python mostly and some small services in Go/C. Eventually, we resorted to caching the events in memory for a short duration and also tuning the GC settings on those nodes as we are doing a lot of young generation collections. We also use bug bounty programs and engage in whitehat testing companies. Data interdependence.
