The iPhone 5s' high-speed camera can be used to take pretty pictures — or to assist in troubleshooting if you're having trouble reading a system alert.

This tip was passed on by friend of Lifehacker Matthew J.C Powell, an Australian tech journalist of some note, who recently found himself helping out a friend with his server issues. As Matthew tells it:
I was helping a friend's son get his Minecraft server working under Windows 8. Anyway, after eliminating most of the possibilities I figured that the local IP of his machine might have changed, which would of course bugger the port forwarding.
To check this I tried to run ipconfig from the command line. Problem was, every time I tried to open a terminal it would flash up on screen and disappear instantly. Why, I don't know — and figuring it out would take far more patience than I have with Windows 8.
Solution: I used my iPhone 5s to shoot a video at 120fps, pointed it at the screen, then ran ipconfig. Even at that speed, the window was on screen for only a couple of frames, but I got the info I needed, fixed the port forward, and got the server running.
That's a recipe for a classic tech lifehack in my book. I'm pretty confident that nobody in Cupertino had that in mind when they were building the 5s.
Thanks to Matthew for the tip!
