Boost Blueprint 150: Boost.CircularBuffer boost::circular_buffer allocates its memory once, up front. When it’s full, each new sample replaces the oldest one. Slide a window over a million samples and it never allocates again You can index into it like an array, and the buffer handles the wraparound for you. Standard algorithms work on it as is. Need one contiguous array for an API that takes a pointer? linearize() puts the elements in order, oldest first, in place Use it for rolling averages, recent event logs, undo history, audio buffers Level up your C++ architecture.

Boost Blueprint 149: Boost.DynamicBitset boost::dynamic_bitset<> is sized at runtime and has std::bitset’s operators: &, |, ^, ~, shifts, count(), any() and none(). Set operations run a whole block at a time find_first() and find_next() walk only the set bits, skipping empty blocks whole It also does subset tests, resize, push_back and string conversion. Use it for handling feature flags, permissions and visited sets in graph searches Level up your C++ architecture. Follow @Boost_Libraries for the #BoostBlueprint series #cpp

Boost Blueprint 147: Boost.Signals2 connect() gives you a connection handle. Disconnect it yourself, wrap it in a scoped_connection that disconnects at end of scope, or pause it with a shared_connection_block A slot can track a shared_ptr to its owner. When the owner is destroyed, the slot stops firing and gets cleaned up. No calls into dead objects Signal operations are thread-safe: one thread can connect or disconnect while another fires the signal. And if slots return values, you decide how they're combined Level up your C++ architecture. Follow @Boost_Libraries for the #BoostBlueprint series #cpp
