为什么 Opera 总做那些别人不做的 HTML5 新功能？
例如 Opera 是最先做 Web Database 的，那时候别人都做 Storage 。现在很多表单输入类型（如日期）都只有 Opera 做。感觉另外几家浏览器都做主流功能，所以功能覆盖重叠很大。 Opera 则专门做非主流功能。
回复内容：
opera擅长引领潮流，创造领先功能。悲催的是，市场推广方面总是差强人意。另外难上手是很郁闷的。用opera上网浏览是很简单的，但是在细致的微调和设定上。小白用户就一头雾水了。谷歌浏览器之所以迅速的占领了可观的市场份额。其中简单易用和高速就是其最主要的特色。opera在产品设计和品牌理念上崇尚一种极端的极客精神。面对大众市场，其品牌和产品还有很长一段时间要走。因为大众需要的是市井化的神器，而不是传说中难于驾驭的梭鱼。 Opera在技术上其实经常有些蛋疼的。比如当初不支持XSLT，不支持function caller，不支持getter/setter……当然Opera也经常做一些别人都不做的牛逼特性。 总感觉opera的细节做的都不是很好， 虽然在浏览器技术上可以算一流 opera现在就变成了浏览器中的细分领域，专注于某些特别群体的需求。 感觉opera和国内的金山很像，产品很牛，在运营以及策略上会走弯路。到现在Opera的占有率还和刚发布的时候差不了多少吧？

Real-time protection against face-blocking barrages on the web (based on machine learning)
Jun 10, 2023 pm 01:03 PM
Face-blocking barrage means that a large number of barrages float by without blocking the person in the video, making it look like they are floating from behind the person. Machine learning has been popular for several years, but many people don’t know that these capabilities can also be run in browsers. This article introduces the practical optimization process in video barrages. At the end of the article, it lists some applicable scenarios for this solution, hoping to open it up. Some ideas. mediapipeDemo (https://google.github.io/mediapipe/) demonstrates the mainstream implementation principle of face-blocking barrage on-demand up upload. The server background calculation extracts the portrait area in the video screen, and converts it into svg storage while the client plays the video.
