TypeScript release highlights

These aren't meant to be comprehensive. They're just the features that most interest me. CFA = control-flow analysis.

1.4: union types and better inference on generics using the union type

1.6: JSX, intersection types, generic type aliases

1.8: type params referring to other type params, string literal types

Encrypted dual boot setup with Pop!_OS and Windows 10

How to guide, using LUKS and Bitlocker on Dell XPS 17 9700

This guide is for those who want to use their XPS 17 in dual boot with their (preinstalled) Windows 10 and a new Pop!_OS installation, without giving up Bitlocker Encryption in Windows nor LUKS encryption in Linux.

The only guides that I could find were for Ubuntu, which it should be identical to, but I found the ommission of a few steps to resolve issues that I encountered in my first install attempt. Hoping to save you some trouble, I am sharing the steps that worked for me, linking the original guides that I found useful.

1. Preparation

1.1 Of course: Backup all your data! You always do this when people tell you to, right? Maybe this time better be safe than sorry.
1.2 Safely note your Bitlocker recovery key somewhere off your XPS. Where to find it

	// URL-safe RFC 4648
	//const ALPHABET: &str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_";
	const COUNT: usize = 1usize << 24; // 3 bytes worth suffices for this test
