Eric's Notes: Stumbling through Buck2

I tried to use Buck2 today, inspired by a tweet by @dtolnay.

I've never been especially fond of build systems. I've only written a couple Bazel files following patterns, and only used them if I absolutely had to. It was kind of a necessary but annoying incantation. But I have noticed some discomfort in the past with this, especially with larger and multi-language projects. I'm imagining that fancy build systems may help:

speed up builds (reduce redundant and slow steps)
make environments easier to reproduce (less “it works on my machine!”)
standardize processes across a company (less language-specific tools)

Context

ChatGPT appeared like an explosion on all my social media timelines in early December 2022. While I keep up with machine learning as an industry, I wasn't focused so much on this particular corner, and all the screenshots seemed like they came out of nowhere. What was this model? How did the chat prompting work? What was the context of OpenAI doing this work and collecting my prompts for training data?

I decided to do a quick investigation. Here's all the information I've found so far. I'm aggregating and synthesizing it as I go, so it's currently changing pretty frequently.

How to install Minecraft natively on Apple Silicon, the easiest way possible

1 - Download MultiMC from here

2 - Download Azul Zulu JDK from here (The version you want is Java 17, arm64, macOS, and you download the ZIP file.) Extract the ZIP file, open the folder and copy "zulu-17.jdk" to your home folder.

3 - Download tanmayb123's Minecraft on Apple Silicon package from here. Extract the ZIP and from the folder you are going to copy two files. One, the folder "lwjglnatives", and two, open the Libraries folder and copy "lwjglfat.jar". Move these to your home folder.

4 - Open MultiMC and create a new instance. Right click your instance and click edit instance. Make the following changes:

WebRender benefits

Fundamentally, WebRender is designed to render CSS with better performance on modern hardware than what the traditional combination of a legacy painting API like Skia and a compositor can offer. It does so by merging the painting and compositing steps together into a single API, avoiding the performance pitfalls associated with CSS properties that don't run on the compositor. Instead of an immediate mode API in which objects are rendered back-to-front, WebRender uses a retained mode API that can render objects in any order. Ultimately, WebRender works more like a game engine than a legacy PostScript-like 2D API, which is

I think I’ve figured out most parts of the cubical type theory papers; I’m going to take a shot to explain it informally in the format of Q&As. I prefer using syntax or terminologies that fit better rather than the more standard ones.

Q: What is cubical type theory?

A: It’s a type theory giving homotopy type theory its computational meaning.

Q: What is homotopy type theory then?

A: It’s traditional type theory (which refers to Martin-Löf type theory in this Q&A) augmented with higher inductive types and the univalence axiom.
