Zoom Web SDK doesn’t support gallery view in Safari, Chrome and Firefox by default.

Gallery view is where multiple participants of a meeting are visible at the same time.

The reason is that SharedArrayBuffer isn’t available in browsers by default.

Safari doesn’t support it right now.

Chrome enables it after achieving Cross-Origin Isolation on the website or by opting into a Chrome Origin Trial(which one?)

Firefox enables it only after achieving Cross-Origin Isolation.

Cross-Origin Isolation is pretty difficult to achieve practically. It requires you to have Cross-Origin-Embedder-Policy(COEP) and Cross-Origin-Opener-Policy(COOP) headers on the main document.

You can’t avoid it on the main document by having the zoom video portion of your website in an iframe because it requires that iframe also has to be in Cross-Origin Isolation.

I have started regularly updating my blog recently (after almost 9 years) and I thought that's a nice push for me to set up RSS for my Blog. So here is my RSS Feed.

My website is powered by SvelteKit which is a very performant and easy to use framework. I quickly set up the RSS using https://github.com/mhatvan/markushatvan.com/blob/master/src/routes/rss.xml.ts and now it is automatically generated at build time.

Some of the things I learned

Don't expect feeds to be updated within minutes or even hours. There are a lot of RSS Readers available and they have different techniques to pull the data from the feed. Some make it configurable. Some make it non-configurable and do it based on how frequently that RSS is updated.
- Google is going to do it very frequently as per this article from TechCrunch https://techcrunch.com/2021/05/19/undead-again-google-brings-back-rss/#:~:text=the web-,A Google spokesperson told me,RSS,-was one

Don't immediately update your RSS feeds. Schedule it to be done on some action or make it time-based like 2 hours after the article is published. This is because once a Feed item has been crawled by some reader, it can be almost impossible to get that item updated in the reader later.
