Can anyone tell me what is the difference between this M365 Copilot app and the Excel app?

If the Copilot app have all the full Word, Excel and Powerpoint feature, then why I need to install 3 more apps?

The mysterious YouTube algorithm brought me to yet another niche video
This time, it's "Why you can't go faster than light"

But surprisingly, this channel gave me the most intuitive explanation ever to this question 😄

I never understood why you can't go faster than light - until now!

I always hear news reporters say “QUOTE” when quoting someone

But I seldom hear them say “unquote”

So when do the quotes end?

An I the only one wondering?

If you created a new #AWS account with #FreeTier

DO NOT follow the console recommendation to create IAM Identity Center with AWS Organization, it will EXPIRE all your free credit ❗❗❗

If you want to use IAM Identity Center, create it on account instance!

TIL, you only need write access on a #GitHub repo to manage variables and secrets, even under environment. No admin access required🫨

It's just that it can't be accessed via UI, you need to use API or gh cli

They have mention it in the credit section, the end of the README

But they also removed the previous versions from the CHANGELOG, making it looks like their release is the first version

Whether this is considered “Credit” is debatable but it just looks cheeky to me

Copying the entire repo of another project and publishing it as your own project, and just vaguely mentioning the original project at the end of the README

Is it a standard and good-faithful way of open-source projects???

If you don't want your team create any exportable ACM cert, you can use the IAM policy condition "acm:Export"

Example: gist.github.com/richardfan11...

Good news, ACM cert can be exported and used outside AWS now
Bad news for security team: you probably want to block this action from most of your AWS account or set monitoring on it.

Why is #terraform #aws provider documentation showing warning of "5.99.1 not the latest version" instead of "6.0.0-beta2 is a beta version"?

I thought people expect the latest stable version as the default instead of a beta one
