1. Introduction (Highlighting Leadership)

I am Jiacai Liu (@jiacai2050), a core maintainer and contributor deeply embedded in the Zig and Systems Programming ecosystems. My work spans from building high-performance databases to curating the foundational learning resources for the Zig language.

2. Key Open Source Impact

My contribution to the open-source community is focused on three pillars:

• Community Infrastructure (ZigCC): As a core maintainer of the zigcc organization, I lead the curation of Awesome Zig and the development of Zig Cookbook. These are the primary entry points for developers worldwide to discover libraries and learn best practices for the Zig programming language.

C++各版本核心特性快速使用指南（附极简示例）

结合C++演进路径，聚焦各版本最实用、工业界高频使用的核心特性，每个特性配可直接运行的极简示例，兼顾语法理解和快速上手，从基础到现代C++逐步推进，适配开发实践需求。

一、探索期（C with Classes/Early C++）：C++基础核心（1980-1985）

这一阶段的特性是C++的底层基础，后续所有版本均完全兼容，是入门和开发的必备核心，无编译器版本限制。

1. 类（class）+ 封装 + 构造/析构函数（C with Classes 1980）

核心作用：C++面向对象的基础，将数据和操作数据的函数封装为一个整体，解决C语言无面向对象能力的问题。 示例：

#include 

jiacai2050

const std = @import("std");
pub const c = @cImport({
    @cInclude("rocksdb/c.h");
});

const key = "hello";
const value = "world";

pub fn main() !void {
    const opts = c.rocksdb_options_create();

How to use this gist

You've got two main options:

jiacai2050

const std = @import("std");

const BIND_HOST: []const u8 = "0.0.0.0";
const BIND_PORT: u16 = 8090;
const NUM_WORKER_THREADS: u32 = 16;
const DOWNLOAD_DIR: []const u8 = "/tmp";
const MAX_FILE_SIZE: usize = 1024 * 1024 * 500; // 500M
// const UPSTREAM_URL: []const u8 = "https://fs.liujiacai.net/zigbuilds";
const UPSTREAM_URL: []const u8 = "https://ziglang.org";
