#开源项目
krep - 一个C写的高性能的字符串搜索工具
github.com/davidesantangelo/krep
krep 的设计以性能为主要目标：
🌟内存映射 I/O：避免昂贵的 read() 系统调用
🌟优化算法：默认使用 Boyer-Moore-Horspool 算法
🌟SIMD 加速: 在可用时利用 SSE4.2 或 AVX2
🌟多线程: 并行处理大文件的块
🌟最小化内存分配: 减少内存开销和碎片化
感觉可以拿来学一学SIMD编程，正好不会。

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
