This recipe is a work in progress and has never been run as-is.

• timeouts are in ms
• lock timeout: in postgres, when a statement that wants a restrictive lock waits on another lock, other statements that want locks can't jump the queue. so even though the statement that is waiting might only take a very short amount of time, when it starts running, while it is waiting no other statements can begin. So we set the lock timeout pretty low and retry if we don't get it.
• statement timeout: we set a short statement timeout before statements which do lock and which we expect to take a short amount of time, just in case something about our assumptions/understanding is wrong and the statement ends up taking a long time. if this happens the statement will bail early without causing harm, and we can investigate what is wrong with

Use macOS-style shortcuts in Windows / keyboard mappings using a Mac keyboard on Windows

Make Windows PC's shortcut act like macOS (Mac OS X) (using AutoHotkey (ahk) script)

With this AutoHotKey script, you can use most macOS style shortcuts (eg, cmd+c, cmd+v, ...) on Windows with a standard PC keyboard.

There is a new, alternative project that does similar things and more, check it out at https://github.com/stevenilsen123/mac-keyboard-behavior-in-windows

How does it work

First and foremost you need to set the CORS configuration for your bucket. I'm a Java developer so here's the code I wrote using the AWS Java SDK v2 to define the CORS configuration for my R2 bucket. Alternatively you can also edit your bucket CORS configuration using Postman following the tutorial at https://kian.org.uk/configuring-cors-on-cloudflare-r2/

// update the config section here with your information first
String bucketName = "YOUR_BUCKET";
String accessKeyId = "YOUR_R2_ACCESS_KEY_ID";
String secretAccessKey = "YOUR_R2_SECRET_ACCESS_KEY";
String accountId = "YOUR_ACCOUNT_ID";
URI uri = new URI("https://" + accountId + ".r2.cloudflarestorage.com");
