#开源项目
著名开源内存分配库jemalloc ，于2025.06.03被归档（貌似被转移到FB组织下了，见：https://github.com/facebook/jemalloc ）。FB旗下的著名存储引擎Rocksdb，虽然还没有被归档，但是项目也不怎么活跃了，项目的核心开发者也离职了。
即使在大公司，做Infra看起来也不是一个好的方向。

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.
