#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。

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
