Can anyone explain what the actual problem is they're solving using 'edge computing'? I get the feeling this is a completely unnecessary use of technology.
You cannot seriously tell me that creating a predictive model for cooking french fries requires a lot of computing power.

I've worked in a fast food restaurant and one of the key pieces of information we used was something called a "drop chart". This was basically a printed out excel sheet with predicted amounts of food to keep ready to serve. i.e. between 5pm-6pm have 12 chicken breasts already cooked. People follow these charts to know how much stock to pre-cook before the hour basically. These predictions are usually based on previou…
ML implies lots of training data. That gets done centrally as it would need to be done in aggregate. You don't have low-latency training of a model and use that same model in real-time. And in your example (admittedly small scale) 12 items of data an hour is not exactly high-data-rate, not enough to justify racks of machines.

Also curious, does GP have some way to shutdown gracefully when the car turns off, and reboot fast when it turns on? You could potentially handle this with a laptop and some battery-settings but not aware of an external battery solution for the NUC.
I currently use a laptop power adapter for the cigarette lighter, which is only on when the car is. The NUC's BIOS is set to turn it on when the power comes on, but I power it off manually before turning off the car. This is not ideal. There is an external battery solution for the NUC, and I bought it! http://www.mini-box.com/NUC-UPS But I haven't switched to it yet. The big upside is that it will gracefully shutdown…

> compute loads What are you computing? This is what everyone is wondering.
There is no real edge-compute loads here, just traditional CRUD data entry type systems. Riding the hype-wave methinks....
I’m not a fan of hype... k8s is one of the few hyped technologies that has delivered on its promises.

I've never been to a retail establishment with anything close to the credit card speed of CFA. The cashier can swipe and grab receipt in one smooth and quick motion. It's so fast you feel like it's broken or slight of hand. I wonder how they do it or why other companies can't or don't do it. CFA stores are so much busier than even an average McDonald's, maybe the efficiency gains are just worth more. No idea how they…
From what I understand, merchants can do a quicker swipe (basically record the card # and transaction amount without waiting for authorization), but the merchant fees are slightly higher because of the possible higher fraud/chargeback rate. It's up to the chain to decide on what to do. Perhaps CFA can do it even better since they could possibly keep a database of bad cards at the edge. Remember those books that cashi…
If you want to see the actual hardware used at the restaurant, check out the previous blog post: https://medium.com/@cfatechblog/bare-metal-k8s-clustering-at... Spoiler: It's a stack of Intel NUCs.
NUCs are surprisingly well-built little machines. I have one in my car, and I give them my absolute seal of approval. I've heard of people running little VMware clusters on them too.

Political values are important to point out. Companies create these tech blogs as a recruitment vehicle. You should know if the company you're considering applying to is funding bigotry (or "wholesome family values" if that's your angle).
Like IBM or Facebook?

Their tech stack is similar to what you'd expect from any large tech company. I can't speak much to the server side of things (I worked on the iOS app) but I know they had everything ranging from older monolithic .NET apps to Node and Go micro services. Their GitHub page ( https://github.com/Nordstrom ) doesn't have much in the way of internal projects, but it has lots of forks that will give you an idea of some of t…
Nordstrom also does polymorphic React with server-side rendering via .NET [0]. I've always been impressed with this part of their stack. [0] https://libraries.io/github/Nordstrom/React.NET
Unrelated but I've done a good amount of nonprofit work and everytime I've had to ask for food donations chickfila has given food free of charge.
At the same time, they harbor beliefs which are incredibly damaging to both me and those I love, so I keep a healthy distance while understanding that they mean well.
Don’t mistake their kind acts for open-mindedness or acceptance, though.

If they had OOBM of some kind I would ditch all my hardware at home and replace it with them.
