Hey HN,For a 4 week dev tool/library project for the bootcamp my spouse is enrolled in, she is looking into using GraphQL as the main technology. Do you have any feedback/suggestions on technical issues or usability issues that you have encountered when developing applications using GraphQL? This project is for resume purposes, and will be put together by a team of 5.They're capable of doing...

Also unclear to me whether Interactive Brokers transparently moves funds to brokerage accounts domiciled in your new jurisdiction, triggering FATCA filing requirements, and if they do a good job of making these clear to customers.

Even if we were to grant that these claims are true, we still have to ask what classes of application benefit from slower, more expensive distributed systems. Blockchains solve only one problem, which is consensus formation on ontrusted networks. They do not solve politics, governance, downtime, and certainly not application failure.. these things all exist on blockchains.
Essentially none of the application ported from centralized systems to Ethereum or even Bitcoin actually face Byzantine consensus issues when deployed as centralized systems. Bitcoin can be used as a 24x7x365 global collateral and value transfer instrument - such a system would face consensus problems if implemented on top of traditional banking infrastructure. That's hugely valuable, but pretty much the only problem-solving application to date.
For things like asset ownership and transfer, any kind of voting, real estate, IPOs, etc, most people still have to deal with incredibly bad centralized systems, that would be amazing if rebuilt as centralized node.js apps that talk to a MySQL database. This stuff is low hanging fruit that's a huge pain for massive swathes of humanity. And despite the fact that no Palo Alto real estate broker is talking to the city's land deed system over unreliable networks, where enemy messengers might swoop in and assign your deed to the wrong buyer, there's this myth that we need distributed consensus for this and other problems best solved by... databases.

If I am developing user docker-compose, I want to deploy that way, too - at least until I reach scale, at which point I want scheduling and orchestration tools, e.g. Swarm.
For easier disaster recovery, it's very convenient if these scheduling/orchestration tools let you deploy in the same way cross-cloud-provider. Swarm can run on AWS/Azure/GCE/bare metal, whereas ECS (which doesn't support Swarm and has its own scheduling/orchestration toolset) can only run on ECS.
+1 to MS for thinking about native tooling up-front.
