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。

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
