unit libraries for us? …yes!Are physical unit libraries for us? ● “Physical units don’t cover our use cases” ○ Not just about “physical” quantities/units ● “Don’t handle non-linear units” ○ nholthaus …Digital audio considerations… ● Mostly operating on float ● Don’t want unnecessary conversions ● Use 3rd party APIs (float, unsigned) ● “Modulation rate” is a frequency (Hz)Musical tempo …MIDI example PCM²}What’s next?Are physical unit libraries for us? ● Do all my examples work in Xcode 15? ● Should we use Au in the meantime? ● Contribute to decibel units in mp-units ● Experiment with FFT and complex numbers

Python? ● Writing extensive APIs in Python - low boilerplate ● Familiar for domain experts ● Easy to use ○ Amazing interactive support out of the box (IPython) ○ Jupyter notebooks provide a great research time, others use python to do that Everything compiled with clang++12 -fPIC -O3Some perf numbers: per increment runtime https://news.ycombinator.com/item?id=34663930 Out in the wild case of noticing high boost::python::object ○ boost::python::object is a smart pointer around a PyObject* ○ Only useful to use bpy::object if you’re going to keep it around ○ Why would we want to do this?Arguments to functions

start this talk by introducing the taxonomy of design patterns at a high level, how to read a UML diagram (as a quick refresher), a refresher on inheritance vs composition, and then spend the rest of the implementation of several design patterns. Attendees will leave this talk ready to implement and use design patterns in C++. 4 The abstract that you read and enticed you to join me is here!Who Am I them ● Pragmatically ○ How to implement/use a Creational Pattern ■ Singleton in C++ ○ How to implement/use a Structural Pattern ■ Adapter in C++ ○ How to use a Behavior Pattern ■ Iterator in C++ 6What

XOffsetDatastructure • X + Offset + Datastructure • Offset • Offset-based Pointers • Memcopyable // We use Offset-based pointers instead of raw pointers. This approach allows us to create data structures that XOffsetDatastructure • X + Offset + Datastructure • Offset • Offset-based Pointers • Memcopyable // We use Offset-based pointers instead of raw pointers. This approach allows us to create data structures that structures, including: • Base Types, Custom Types, Different Containers, Nested Types. • The diagram shows how these base types and containers can be combined to form complex data structures.

say “algebraic”? Okay, that was product types. But there’s another mathematical operation we can use! tuple holds a char value and a bool value. variant holds a char value or a MSVC all use this same layout, with a 4-byte index field.Finally, optional is another sum type optional is the other sum type. Like pair, optional has been optimized for certain common use-cases. An arrived in C++17, alongside optional and variant. ● It is not an algebraic type. We can’t use math to say anything interesting about its domain, which is “union of all copyable types.” ● std::any
