#方法论
写技术博客时，我很喜欢画图来表达原理。也因为自己画的图多了，有了一层感悟：但凡能把技术原理通过画图清晰表达出来的，一般文章内容也不会太差。这是因为，画图不同于文字和简单的贴代码，是经过作者理解了原理再翻译成图形语言的。
按照这个推论，得到一个搜索优质技术文章的技巧：使用Google搜索技术文章时，以前是根据关键字搜索相信搜索引擎的排名，现在可以试一下切换到Google搜索中“图片”那一栏看看。图片这一栏可以在不用点击文章的情况下马上看到文章中的一些缩略图，根据画的缩略图能大体判断文章的质量。

Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
