Ruminations on lambda captures

by Ville Voutilainen

Excerpt:

The proposal for capturing *this by value (P0018) raised suggestions for a "true value capture", which led to suggestions to change capture-default that defaults to by-value capture([=]) in the case of capturing class members. This paper explores what the suggested changes to the capture-default might mean. This paper specifically doesn't try to claim that any of the changes would have an effect on any particular amount of existing code, and admits that the examples in this paper are somewhat concocted and for illustrative purposes only.

Using parallelism with boost::future

by Jens Weller

From the article:

... While I'm fine with that the application locks up kind of hard during writing a GB zip file (its only job), I'd like to be as fast as possible. Thats why I decided to parallelize the part of the application that reads the file paths via boost::filesystem...

Discussion about std::thread and RAII

by Ville Voutilainen

Excerpt:

C++ continues not to provide a thread type that would join() automatically on scope exit. This causes exception-safety problems, because failing to join() in all code paths causes the destructor of a std::thread to terminate(). This paper explores various ways to solve the problem.
