[Boost-users] Compile and run Boost examples online
by Antony Polukhin 25 Sep '15

25 Sep '15

Hi all, I've just launched the beta version of online examples for the "Boost Application Development Cookbook": http://apolukhin.github.io/Boost-Cookbook-4880OS/ There you can do online compilation of Boost related code, run examples, freely experiment with code from the book, read intros for the code and play around with the Boost libraries. I hope the site would be useful! P.S.: If you wish to report an error or wish to have some functionality added to the site, use the "Issues" link at https://github.com/apolukhin/Boost-Cookbook-4880OS or even make a pull request. P.P.S.: Intros for Chapters 7-12 are missing at this moment. I'll add them in a few months, sorry for the delay. -- Best regards, Antony Polukhin

Boost.Fiber mini-review September 4-13
by Nat Goodspeed 04 Sep '15

04 Sep '15

Hi all, The mini-review of Boost.Fiber by Oliver Kowalke begins today, Friday September 4th, and closes Sunday September 13th. It was reviewed in January 2014; the verdict at that time was "not in its present form." Since then Oliver has substantially improved documentation, performance, library customization and the underlying implementation, and is bringing the library back for mini-review. The substance of the library API remains the same, which is why a mini-review is appropriate. The Fiber library now requires a C++14-conforming compiler. I will monitor reviews and discussion on both the boost-users@ list and the boost@ developers' list. Please include at least "fiber" and "review" in your mail subject, e.g. by replying to this message. (Please reply to only ONE list, however.) Thank you for your interest and your feedback! ----------------------------------------------------- About the library: Boost.Fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperatively. The API contains classes and functions to manage and synchronize fibers similar to Boost.Thread. Each fiber has its own stack. A fiber can save the current execution state, including all registers and CPU flags, the instruction pointer, and the stack pointer and later restore this state. The idea is to have multiple execution paths running on a single thread using a sort of cooperative scheduling (versus threads, which are preemptively scheduled). The running fiber decides explicitly when it should yield to allow another fiber to run (context switching). Boost.Fiber internally uses execution_context from Boost.Context; the classes in this library manage, schedule and, when needed, synchronize those contexts. A context switch between threads usually costs thousands of CPU cycles on x86, compared to a fiber switch with a few hundred cycles. A fiber can only run on a single thread at any point in time. docs: http://olk.github.io/libs/fiber/doc/html/index.html git: https://github.com/olk/boost-fiber --------------------------------------------------- Please always state in your review whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?
