Be careful when posting photos on-line. Almost all new smart phones record where and when you took a photo. Many of the new high-end dedicated cameras do the same thing. Beyond the photo that you see and innocently post is a wealth of data you may not want to publish. That data is called EXIF, for Exchangeable Image Format.
Smoke testing is a term used to describe the testing process for servers after patches are applied.
The process typically involves making sure servers are rebooted in the right order, making sure they have completely rebooted, restarting applications in the right order, and then testing to be certain everything is working properly when users return to work in the morning.
This typically takes 30 minutes per server, depending upon your environment.
PCs are not typically smoke tested, or if so, not all of them.
