I guess this is public now – Sergey invited me to give the keynote at C++ Siberia 2017 which will be held in Tomsk in August (25th and 26th).
This will require some serious mental and physical preparation. I’ve never had a talk two hours long. :)
If you are in area, and you speak Russian (My keynote will be in English since, despite having a Russian-sounding name, I don’t speak Russian), come and join us – the tickets are available at the conference website.
