Introduction

Apple restricted the access to Xcode LLM (Predictive code completion) feature on China models of Mac. This guide provides a way to bypass that restriction. It's verified on macOS 15.0 Beta (24A5264n), but there is no guarentee that it will always work on later macOS versions.

Prerequisites

• Xcode is installed and run at least once.
• SIP debugging restrictions are disabled (via csrutil enable --without debug command in recovery mode).

// The string struct will hold our data

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

zkCoins

zkCoins is a novel blockchain design with strong privacy and scalability properties. It combines client-side validation with a zero-knowledge proof system. The chain is reduced to a minimum base layer to prevent double spending. Most of the verification complexity is moved off-chain and communicated directly between the individual sender and recipient of a transaction. There are very few global consensus rules, which makes block validation simple. Not even a global UTXO set is required.

In contrast to zk-rollups there is no data availability problem, and no sequencer is required to coordinate a global proof aggregation. The protocol can be implemented as an additional layer contained in Bitcoin's blockchain (similar to RGB[^5] or Taro[^6]) or as a standalone sidechain.

The throughput scales to hundreds of transactions per second without sacrificing decentralization.

Design Principles

The core design principle is to *"use the chain for what the chain is good for, which is an immutable order

关于 URL Scheme 你知道多少？

iOS系统中

由于苹果的各应用都是在沙盒中，不能够互相之间访问或共享数据。但是苹果还是给出了一个可以在APP之间跳转的方法：URL Scheme。简单的说，URL Scheme就是一个可以让 APP 相互之间可以跳转的协议。每个 APP 的URL Scheme都是不一样的，如果存在一样的URL Scheme，那么系统就会响应先安装那个 APP 的URL Scheme，因为后安装的 APP 的URL Scheme被覆盖掉了，是不能被调用的。
