Cursor's Memory Bank

I am Cursor, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.

Memory Bank Structure

The Memory Bank consists of required core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:

Emulating Raspberry Pi 4 with Qemu

Just a quick update before we dive in: what we're actually doing here is running Raspberry Pi OS (64-bit) on a QEMU virtual ARM setup. This isn't full-blown hardware emulation of the Raspberry Pi 4, but more about creating a virtual environment for the OS. It doesn't mimic all the specific hardware features of the Pi 4, but it's pretty useful and great for general testing. I turned to this solution mainly to extract a modified sysroot from the Raspberry Pi OS, something not readily available in other resources. For those looking into detailed emulation of the actual Raspberry Pi 4's hardware in QEMU, check out this link for the latest updates: https://gitlab.com/qemu-project/qemu/-/issues/1208.

Hope it helps! :D

Shortcomings: No GUI yet, only console.

Steps

Database Environments

A schema contains a group of tables. A database contains a group of schemas.

In prod, we use a cloudsql PostgreSQL instance. The reports DB is for prod only. It's presence should be a gatekeeper to prevent destructive teardowns.

Everywhere else, we assume a local PostgreSQL running on port 5432 with two existing databases. The khan_test DB is for integration tests. The khan_dev DB is for local development.

Installing MTGA on macOS using Wine, and making it look pretty!

The following instructions are heavily inspired by /u/uhohohdear. I modified uhohohdear's instructions and then added support for Retina/HiDPI displays and instructions about how to update MTGA.

IMPORTANT UPDATE: This will no longer work if you upgrade to macOS Catalina, as Wine and Wineskin are 32-bit. I'll update this Gist with 64-bit versions when they become available.

~~We're back in business!~~

It appears that the workarounds no longer work. A few people with Macs using Nvidia graphics cards are having success, but Macs with Intel and AMD GPUs crash regularly. At this time, the best way to play Arena on Mac is via Boot Camp or GeForce Now.

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

	Docusaurus CSS Variables.

	I'm making this since I wanted to customize my Docusaurus site theme, but couldn't find a proper list of all Infima CSS variables
	the static site generator uses. Thus, I basically copied the root of my site's CSS (along with other vars I found), and made a list
	of them that categorizes the vars.

	TABLE OF CONTENTS:

	-- crc32c https://tools.ietf.org/html/rfc3385#section-4.1
	-- Table-based crc32 (not exactly right algorithm, but a good pattern to follow)
	-- https://gist.github.com/cuber/bcf0a3a96fc9a790d96d
	-- Google-created CRC table
	-- https://github.com/googlearchive/crc32c-java/blob/master/src/com/google/cloud/Crc32c.java
	CREATE OR REPLACE FUNCTION update_crc32c(src TEXT,
	crc BIGINT DEFAULT 0)
