I was told by @mmozeiko that Address Sanitizer (ASAN) works on Windows now. I'd tried it a few years ago with no luck, so this was exciting news to hear.

It was a pretty smooth experience, but with a few gotchas I wanted to document.

First, download and run the LLVM installer for Windows: https://llvm.org/builds/

Then download and install the VS extension if you're a Visual Studio 2017 user like I am.

It's now very easy to use Clang to build your existing MSVC projects since there's a cl compatible frontend:

In shader programming, you often run into a problem where you want to iterate an array in memory over all pixels in a compute shader
group (tile). Tiled deferred lighting is the most common case. 8x8 tile loops over a light list culled for that tile.
Simplified HLSL code looks like this:
Buffer<float4> lightDatas;
Texture2D<uint2> lightStartCounts;
RWTexture2D<float4> output;

Implementing Algebraic Effects and Handlers

Algebraic Effects in JavaScript part 4 - Implementing Algebraic Effects and Handlers

This is the final part of a series about Algebraic Effects and Handlers.

So we've come to the core topic. The reality is that we've already covered most of it in the previous parts. Especially, in the third part, where we saw delimited continuations at work.

Capturing continuations with Generators

Algebraic Effects in JavaScript part 2 - Capturing continuations with Generators

This is the second part of a series about Algebraic Effects and Handlers.

Note: initially I planned a 3-part series, but since the current post on undelimited continuations ended up taking

Operational Introduction to Algebraic Effects and Continuations

Algebraic Effects in JavaScript part 1 - continuations and control transfer

This is the first post of a series about Algebraic Effects and Handlers.

There are 2 ways to approach this topic:

  • Denotational: explain Algebraic Effects in terms of their meaning in mathematics/Category theory
  • Operational: explain the mechanic of Algebraic Effects by showing how they operate under a chosen runtime environment

Both approaches are valuables and give different insights on the topic. However, not everyone (including me), has the prerequisites to grasp the concepts of Category theory and Abstract Algebra. On the other hand, the operational approach is accessible to a much wider audience of programmers even if it doesn't provide the full picture.

Gatsby bootstrap lifecycle

Sequence of Gatsby's bootstrap lifecycle with links to source code as of v2.0.0

  2. load plugins (load-plugins/index.js) from the list given in gatsby-config.js
  3. onPreBootstrap: runs onPreBootstrap if it is implemented in any plugins, for example gatsby-plugin-typography. Receives handy [apiCallArgs](https://github.com/gatsbyjs/gatsby/blob/ffd8b2d691c9
