function [ q3 ] = slerp( q1, q2, t )
%SLERP quaternion slerp
%   computes the slerp of value t between quaternions q1 and q2

q1 = q1 ./ norm(q1);
q2 = q2 ./ norm(q2);

one = 1.0 - eps;
d = q1'*q2;
absD = abs(d);

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Wifi on Ubuntu 18 server

TLDR

1. Install wpasupplicant
2. Turn on wifi radios: sudo nmcli radio wifi on
3. Check your devices are recognised even if they're not "managed": sudo iwconfig
4. Check your wifi (here called "wlp3s0") is capable of detecting nearby routers: sudo iwlist wlp3s0 scan
5. Configure netplan by dropping a file called 01-netcfg.yaml into /etc/netplan/ or edit existing file there. See example below.
6. netplan try, netplan generate, netplan apply.
