It’s time for, not one, but two brand-new, up-to-date talks on the state of the art of concurrency and parallelism in C++. I’m going to put them together especially and only for C++ and Beyond 2012 , and I’ll be giving them nowhere else this year: C++ Concurrency – 2012 State of the Art (and Standard). And there’s a lot to tell.

The early days at Sun Cambridge were special, I absorbed a lot about networking and the technical side of the role from my fellow systems engineer Martin Baines, and we were driving all over the region in cool company cars (I had a Citroen BX 16V) selling a really hot product. He had it up and running on Wednesday. that a lot of people used.

But Go is now the sixth most-used programming language, trailing only Python, Java,NET, and C++. But ML/AI-related topics such as natural language processing (NLP, +22% in 2019) and neural networks (+17%) recorded strong growth in usage, too. Drop.NET from the tally on methodological grounds [2] , and Go cracks the top five.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks. If your average visitor is on a fast cabled or cellular network, they probably won’t benefit from the new protocols all that much. An often used metaphor is that of a pipe used to transport water.
