我特别喜欢在技术文章中画图，有两个原因：对作者而言，如果能用图表达思路，侧面说明是真的掌握了；对读者而言，图形也比一维的文字更容易理解、信息量更大，图形中可以增加联系、颜色、形状等多维度信息。
所以一方面要让自己真的掌握一个知识点，另一方面要锻炼自己的画图表达的能力，以画图来反向验证自己对知识的掌握。画图的一些心得，参考我以前写的文章：《技术配图的一些心得》。
至于我用的画图工具，现在如果是随手画的图，就用excalidraw；一些更为正式的图，就用Mac上的OmniGraffle，可以很方便得对齐、调整颜色、字号大小等等，大几百买断的单机单平台软件，但是超值。

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.
You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit.

One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels.
