▎ OrbStack
> 也许是 “macOS 上的 WSL” ？
OrbStack 可以便捷地管理 Docker 和 Linux 环境。虚拟机支持十多种 Linux 发行版，支持 Intel 和 Apple Silicon CPU。
根据 官网 的介绍，你可以方便地传输或管理虚拟机/Docker 中的文件；可以在 macOS 上快速进入虚拟机，也可以在虚拟机中调用 macOS 的命令。另外，它的启动速度很快，并且闲置占用低。
我在 MacBook Air M2 上简单测试了一下，冷启动虚拟机确实很快。需要注意的是，目前每次创建新虚拟机都要联网下载资源，需要比较好的网络环境。
目前 OrbStack 在公测阶段，可以免费使用。官网：https://orbstack.dev

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
