Better right-click menu in Win11
2023-06-22 windows When the Windows system was updated to version 11, the right-click menu was completely redesigned. Microsoft is apparently trying to make it simpler and more modern, but the way they have chosen to do it is really brute force: hiding everything useful in the secondary menu! I find this really annoying. Luckily, we have a way to bring back the classic, and even customize it and make it better! (This post is in Chinese.)

C++ const 用法汇总

Edge 扩展推荐
2022-08-25 edgebrowser 2019 年 7 月写过一篇 Chrome 插件推荐的文章，那时候我还在用 Chrome 作为我的主要浏览器。一晃三年过去了，我也早已从 Google Chrome 转入全新 Chromium 内核构建的 Edge 浏览器。微软倒蛮有意思，自己从头开发的东西不咋地，在别人的平台上倒是表现得相当好。由于国内的水土不服啊，我用 Chrome 时总会遇到同步不了的情况，这点的体验在 Edge 这儿得到了很好的改善，也是我用 Edge 的主要原因吧。前些天帮很多同学做新机开荒，也推荐他们就用这款“Win11 原装”浏览器。当然一个浏览器肯定是离不开扩展的，趁着帮他们开荒这个机会，也顺便整理了我认为必备的一些浏览器扩展。
