### AI overview

This tutorial explains how to use one JavaScript function to draw regular shapes on an HTML canvas. It begins with a hexagon and generalizes the approach using the center point, radius, number of sides, angles, and trigonometric calculations, allowing triangles, squares, octagons, and repeated shapes to be created by changing parameters.

### Source excerpt

Learn how to use JavaScript to draw any regular shape to a HTML canvas with a single function, and how to modify it to draw multiple shapes.

### AI overview

The article explains how Shopify Spin runs Kubernetes-based development instances in containers, with systemd managing initialization and workflows. It examines node instability and pod relocations linked to memory exhaustion after infrastructure changes.

### Source excerpt

The Spin infrastructure team works hard at improving the stability of the system. In February 2022 we moved to Container Optimized OS (COS), the Google maintained operating system for their Kubernetes Engine SaaS offering. A month later we turned on multi-cluster to allow for increased scalability as more users came on board. Recently, we've increased default resources allotted to instances dramatically.

### AI overview

This tutorial derives the double-angle sine and cosine identities by representing planar rotations with a 2x2 matrix, squaring that matrix, and comparing it with a rotation by 2θ.

### Source excerpt

Problem: Derive the double angle identities $$\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\ \cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)$$ Solution: Recall from linear algebra how one rotates a point in the plane. The matrix of rotation (derived by seeing where $ (1,0)$ and $ (0,1)$ go under a rotation by $ \theta$, and writing those coordinates in the columns) is $$A = \begin{pmatrix} \cos(\theta) & -\sin(\theta) \\\ \sin(\theta) & \cos(\theta) \end{pmatrix}$$ Next, note that to rotate a point twice by $ \theta$, we simply multiply the point (as a vector) by $ A$ twice.
