Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Create Self Signed Certificate using OpenSSL on a Mac

Introduction

Every now and then I need to create a self signed certificate in azure for something. In my particular case its Azure B2C. I am using a mac so its not simply just running something like

New-SelfSignedCertificate `
    -KeyExportPolicy Exportable `
    -Subject "CN=yourappname.yourtenant.onmicrosoft.com" `
 -KeyAlgorithm RSA `

cors.py for mitmproxy

Hacking CORS restriction to enable in-browser XHR to any server.

Usage

Say you are running an web app at localhost, and you want to send XHR to http://remote-server:80, but the CORS restriction forbids access because you are sending requests from an origin that remote-server:80 does not allow.

Run:

Complete Recent Discord Quest

Note

This no longer works in browser!

Note

This no longer works if you're alone in vc! Somebody else has to join you!

How to use this script:

Accept the quest under User Settings -> Gift Inventory

Open in Visual Studio Code

Open Automator
Create a new document
Select Quick Action
Set “Service receives selected” to files or folders in any application
Add a Run Shell Script action
- your default shell should already be selected, otherwise use /bin/zsh for macOS 10.15 (”Catalina”) or later
- older versions of macOS use /bin/bash
if you're using something else, you probably know what to do 😉
