Triple trip report from ACCU, C++ Russia and C++Now 2018 – Part 1

by Jonathan Boccara

Going to conferences is a great experience, to learn about your domain and meet people that work in it. Going to conferences can give you tools to write better code.

I’ve had the chance to go to (and speak at) three conferences over a month:

• ACCU in Bristol, UK at the beginning of April,
• C++ Russia in Saint-Petersburg, Russia in mid April,
• C++Now in Aspen, US at the beginning of May.

I haven’t seen many people attending all three of them, so I figured I could make a combined trip report, to give you an idea of what they’re like. And more importantly what you would get by attending either one.

And a huge thanks to the company I work for, Murex, for sending me all over the world of C++!
