Comment on tesco and sainsburys hit with technical issues

Regulatory burden aside, you don’t do data analysis at scale running “some big wigs’ nephew’s VB/C# app.”

I’ve not worked directly with any of these payment systems, but I can’t believe the only solution is go all 90s style Windows based system. There will be embedded ways that comply to regs.
I can see they are Windows based when there is issues. I’m sure of Tesco and Morrisons but Sainsburys I don’t go to often enough to have see an issue that bring up Windows. I was being flippant, but I don’t hold using Windows to build stuff in high regard. In my experience the software engineers who doing that don’t know anything else.

It’s very likely to be one of the NCR platforms. If I were to hazard a guess, StoreLine. Though it could be Encor/ISS45, ECRS has a pretty big market share as well. POS software is a walled garden of security through obscurity. Windows dependencies tend to be in part because it is such a small market, but also due to workstation/server requirements as well as remote support.
Long time support and stability are the name of the game. The industry doesn’t allow for much downtime which makes any change significantly harder than a lot of other industries.

I’m sure these brands/sector will end up Linux too at some point. I’m half expecting MS to move to the Linux kernel themselves in the not too distant future, so no matter how trailing edge they are, they could get dragged in.

I’m out of the industry now, but I was saying the same. Win 10 Embedded and Win 7 IoT both served very, very well. But the always online component and other issues with 11 make it poorly suited for the use case it had in the past. Systems that relied on mapped drives are now nearly fully depreciated.
