                Testing the Windows screenreader NVDA on a Mac
              
          
    How to test NVDA screen reader behaviour on a Mac:


Download Microsoft Edge VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
Download Virtualbox and import the Edge VM image.

Then in the VM:

Install guest addons in the VM
Download & install latest NVDA from nvaccess.org
Download & install SharpKeys and use it to map left an alternative key (eg. Left Ctrl) to the Insert key. This is needed because Macs do not typically have an “Insert” key which is the prefix for many NVDA commands.

                Event-stream based GraphQL subscriptions for real-time updates
              
          
    In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.
Conceptual Model

At the moment GraphQL allows 2 types of queries:

query
mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.
