The past few days, I have been to the Kaimuki location a lot. First to get parts to fix a toilet. Second to get what I forgot the first time. Third, to get parts to build a computer rack for the office. And fourth, to get the parts for the rack I forgot. (Post about the computer rack coming later.)
The other day at the store, I got to the cashier and she started scanning the items I had in my cart. The store was pretty busy and there were only two cashiers working. Not really a big deal, but lines were forming, so she was trying to work fast.
After scanning everything, she looked at the screen on the register and noticed it had stopped responding at some point, so no transaction had started. She cycled the power and waited for it to boot up. City Mill uses POS devices running what looks like Red Hat Linux 7.3 (kernel 2.4.20-8bigmem). What was even more interesting is to see they were using /bin/login as the cashier login handler. The shell (I'm guessing) was configured to be the POS software.
I enjoy seeing my company's software in use in the world. I've seen RHEL and other products everywhere now and it's always in the places I never expect.
I eventually left knowing my credit card data was more safe on a RH-based system than something else. I also left with a t-shirt that says 109 Years of Kama'aina Living.
