Feedback on the distributed C++ meetup

• Post by Jean Guegant
• Lessons:
  • Two-city format is best, 3-city is too much
  • Need breaks
  • 15-min talks are ideal
  • Slides need a bigger font
  • Mandatory NDA is bad
  • Turn the lights on in the audience

Boost 1.67

• Changes
• New libraries:
  • Boost.Contract – Support for contract-based programming

Apple switches from libclang to Clangd

• Announcement

We at Apple have decided to switch focus from supporting the libclang-based tooling infrastructure in order to join forces on the Clangd development efforts. We believe that Clangd is the preferred solution for interactive Clang-based tooling. There has been great work on Clangd already, and we’re going to start investing effort as well to make Clangd faster, more capable, and more efficient.

The C++ committee has taken off its ball and chain

  • Is C++ a language of exciting new features?
  • Is C++ a language known for great stability over a long period?

Modern C++ isn’t memory safe, either

  • C++ vs. Rust alert!

Original STL Library Documentation Recovered by Robert Ramey

• STL Docs

Boris Schäling - Containers in Boost (C++Now 2013)

• Boost.Multiindex – multiple interfaces (indexes) for item lookup
• Boost.Bitmap – a std::map-like container which supports lookups from both sides
• Boost.Container – same containers as in the C++ standard library but with extra comfort:
  • Support for recursive containers
  • Stable versions of vector, set, map; single-linked list
  • SSO
• Boost.Intrusive – containers that store the original objects instead of their copies
• Boost.PointerContainer – manages dynamically allocated objects (similar to std::vector<std::unique_ptr>)
• Boost.CircularBuffer – a fixed-size container that overwrites elements if you add more
• Boost.Lockfree – a lock-free queue and stack that can be concurrently modified from different threads
• Boost.PropertyTree – a serializable key/value pair container for storing configuration data; supports XML, JSON and INI formats
• Boost.Multiarray – a multidimensional array; index-based access returns a subarray; reshaping and resising supported
• Boost.DynamicBitset – like std::bitset but the size can be set/changed at run time
• Boost.Heap – like std::priority_queue but with additional functionality
• Boost.Array – use std::array instead
• Boost.Unordered – use unordered containers from the C++ standard library instead

Edsger Dijkstra:

Program testing can be a very effective way to show the presence of bugs, but is hopelessly inadequate for showing their absence.
