### nodejs/diagnostics

* Expand the scope of deep dive meetings [#417](https://github.com/nodejs/diagnostics/issues/417)
* Good idea
* We can either wait to finish UJ or jump to other topics
* Discuss during issue
* Continue unified hooks discussion [#401](https://github.com/nodejs/diagnostics/issues/401)
* Will continue to work on diagnostics channel stuff
* Will open an issue to share context
* Diagnostics channel: idea from a few years ago to have a general data fire hose(?)
* There were some performance concerns around it
* Trying to redesing so we can still have the fire hose deliberately without overhead when not in use
* Difference between this and Node.js tracing?
* OpenTracing is more (?)
* More like the `debug` module, where you create a named channel and put data there
* Pub/sub system where subscribers subscribe for a particular name
* Construct and produce data _if_ there's a listener for given name
* discuss: node.js contributor survey [#398](https://github.com/nodejs/diagnostics/issues/398)
* Gireesh is not here, so skipping
* Discuss usage and support of eBPF [#386](https://github.com/nodejs/diagnostics/issues/386)
* Removed from agenda
* Reviving "Zones" like proposals to TC39 [#375](https://github.com/nodejs/diagnostics/issues/375)
* Presented on last TC39 meeting
* Didn't advance
* Still some concerns around dynamic scoping
* Will be discussed in an incubator call in a couple of weeks
* No actions from Diag WG in the next few weeks
* Can remove from agenda
* COVID-19 and WG sittings [#370](https://github.com/nodejs/diagnostics/issues/370)
* No changes
* Will close the issue later
* Improving automated remote connection via Inspector Protcol [#348](https://github.com/nodejs/diagnostics/issues/348)
* Will present a demo on next meeting
* \[async_hooks\] stable API - tracking issue [#124](https://github.com/nodejs/diagnostics/issues/124)
* Some async stuff got backported recently that broke older(?) users
* Shouldn't block advancement though
* Apparently Myles has a fix PR somewhere
* Stephen: personally don't see any paths to ever getting it to stable
* From my perspective it's the internals for things that people should actually use, like AsyncLocalStorage
* Eventually we should deprecate it as an exposed thing
* Not now, but when public APIs cover the actual use cases for async_hooks
