I worked for Nordstrom for several years and whenever I describe their technology department to another developer they're always pretty shocked. It was pretty shocking to me when I started there too.

I'm curious about Nordstrom, I know nothing of their infrastructure.

We did a case study on Nordstrom recently in the CNCF, check it out: https://www.cncf.io/case-study-nordstrom/

Here's a recent talk from KubeCon/CloudNativeCon: https://www.youtube.com/watch?time_continue=5&v=xZO9nx6GBu0

Interesting as it seemed that smarter edge/iot nodes would be like ARM/RaspPi, yet it seems it may get even as high as (or just straight to) Intel nuc.

Raspi cannot be used for a semi serious server application due to microsd card write wear issues. All other methods of attaching external storage by USB bus to an rpi are not reliable or suitable for this sort of purpose. Nowhere near the longevity of something with a native sata or m.2 SSD interface and a real SSD.

Does that remain true if you grossly over-provision the SD card? Use a 64GB card for 1GB of data and you have a lot of wear leveling space.

What data does CFA actually /need/ to collect in their restaurants? Orders and supply chain metadata? Store traffic statistics? Cleanliness and user ratings?

I hope it isn't Bluetooth or WiFi (or worse yet, GSM/LTE) metadata from their customers.

If you're going to complain about the ethics related to Chik-Fil-A, it would probably be better to start with the fact that they raise and kill a billion chickens every year rather than that they have donated $120,000 to organizations like the Salvation Army (example from above article).

Eh, regardless of my personal thoughts on the topic, the ethics of eating animals are a lot more controversial among the HN crowd than LGBTQ rights.

Chik-Fil-A is not an arbiter of LGBTQ rights. Their small 6-figure donations to organizations that focus on other issues do very little in the grand scheme of things.

Do you really think Chik-Fil-A is directly causing more suffering by donating to a few charities in amounts this small than by raising in captivity and then killing billions of chickens? I see no way to reasonably argue that.

Imagine feeling the bizarre compulsion to turn every discussion about technology on HN into yet another tedious political argument.

The company themselves chose this political stance, not the community around them.

No, the grandparent's political stance is to be outraged at anybody he/she disagrees with and has an unhealthy obsession to blurt it out on discussions that aren't political.

The write lifespan in DWPD on any sd card is a tiny fraction of the expected lifespan of even a cheap $55 consumer SSD.

Part of the problem is that even if you only write 1GB per day the card is highly likely to reuse the same sectors over and over.

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…

Actually they're a bit of a pioneer in Serverless computing:

Our hypothesis: By making smarter kitchen equipment we can collect more data. By applying data to our restaurant, we can build more intelligent systems. By building more intelligent systems, we can better scale our business.

I was surprised too, when I saw their name in the Devops Handbook; apparently they were one of the pioneers of Devops. Talking with a previous employee, it sounds like they really reinvented themselves from an IT department to a little tech oasis within the company.

You can find some pretty awesome work on "traditional" companies. There are some pretty cutting-edge projects where I work too :) (but way more legacy migrations and boring financial CRUD apps).
