Here at the client site everyone uses Windows 7, since this is not an IT firm. They make jewellery. So I don't blame them.
The problem is their in house dev team are also forced to use Windows.

Today someone from their dev team was with me for a new project. Their senior guy sent us a mail mentioning that the project code is on AWS EC2 instance and we will have to SSH to see it.
I checked the code on my MacBook with SSH and copied it to local using SCP. The dev guy was seeing it in amazement. I asked, what's it?

He just asked, "You don't have to use PUTTY" 😮

I smirked 😏
