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?

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

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

When could #f1 fix this issue?
They are coming to the pitlane under safety car, not changing tyres

I was about to report bug, thinking CloudTrail is exposing sensitive information
Turned out, it's just another form of "HIDDEN_DUE_TO_SECURITY_REASONS"

How many other forms do AWS uses??? 😆

By the time you know your system is complex, it’s already too late.
