A dump of the SwiftUI.framework binary for the iOS simulator (as of Xcode 12.0 beta 2) using the swift-reflection-dump tool.

Note: I used a Swift 5.3 compiler build from a few weeks ago that I had laying around. Because of ABI stability, I don't think the swift-reflection-dump version has to match the compiler version that was used to build the binary, but I'm not 100% sure.

Introducing Bitcoin

Introduction

I’ve been involved in Bitcoin since May 13, 2011 when I read an article about Bitcoin on Hacker News. It struck me that Bitcoin had the potential to be the foundation of a new global industry like the internet, but with money instead of communications. I was hooked right away and spent weeks researching it.
