The C++ language has seen a surge of activity over the last few years, involving the language itself, its ecosystem and the community. Haifa::C++ is a group for C++ developers who would like to expand their knowledge of the language, tools and related technologies. Our group meets once a month for a talk, mingling and hopefully some pizza ;)
And since Israel is a small country, you may also be interested in the southern (to Haifa) community of Core C++ (https://www.meetup.com/CoreCpp). The two groups share the goal of building an Israeli C++ community, and collaborate on various initiatives.
