Same DNA, aren't they? i.e. all created by ex-Goldmans people that worked on SecDB and similar for Mike Dubno [http://dubno.com/wsj/giveaway.html]. I know that is definitely the case for BAML. In fact, Dubno came out of retirement to work there for a while.

That’s what I understand too. (I worked on the Quartz Core team for a couple years at BAML.)

I was at BAML just as quartz was starting, but never worked on it. I heard all the stories of them creating their own bi-temporal database etc.

I also heard in the early days it was a bit resource heavy on a user's machine.

He's definitely talking about JPM. Since he's drawing parallels to AWS Lambda, I reckon he'll be talking about their grid compute.

Not sure when the bank deprecated IE though - it was certainly in use for most internal sites when I left in 2018.

By that they mean chrome is the “strategic” solution and all new things should target chrome. IE is still required for many internal sites. They are setting up to move to Edge so both the old and the new can be accessed in one browser

So that's why Edge exists.

Nah it exists because an endless stream of security bugs is a headache.
