At this moment relu_layer op doesn't allow threshold configuration, and legacy RELU op allows that.
We should add configuration option to relu_layer.

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

noImplicitAny will help with some refactorings (such as ornicar/chessground#145). Even partial progress is useful.

1. Pick one of:

   • ui/analyse
   • ui/puzzle
   • ui/round

2. Temporarily set noImplicitAny to true in ui/.../tsconfig.json.

3. To compile use yarn run dev, yarn run dev --watch or yarn run tsc --noEmit in ui/.... Fix

I run gatling.sh from a script. I encountered multiple occasions where Gatling failed, but the exit code was 0.

Expected behavior: exit code should be non-zero
Observed behavior: exit code 0

I just came across the fact that a Show[Throwable] exists.

1. It is not wired up into import Scalaz._, one needs to import scalaz.std.java.throwable._
2. It discards the stack trace entirely.

What's going on with this? :D
Is it OK if I fix both of these (for 7.2 and 7.3)?

I just tried it out in Dotty for https://devblogs.microsoft.com/typescript/announcing-typescript-4-1-beta/#template-literal-types

Remove all additional resolvers from build.sbt, at least for releases, because artifacts published to Maven central repository should not contain additional repositories, and in fact don't need them because all dependencies are already in Maven central repo.

The plotting UI leaves a lot to be desired:

• When you bring up the plotting UI, it's not obvious that you have to do some work to make a plot happen. If you don't, there's no error message, just a never-ending wait. (see https://gitter.im/polynote/polynote?at=5e0e36f9eac8d1511e9ed2ff )
• Why do we make you drag things onto axes? Especially when there is only one axis it could go onto (at leas

This is a follow-up to #4097 where we used an AtomicInteger as a poor-mans replacement for a Semaphore with tryAcquire (or maybe even drainPermits).

Most awesome FP libraries (Cats, Scalaz, Monocle, Algebird etc ) have microsite done by sbt-microsites

Adding one for Shapeless would make it easier for newcomers. Quick, online reference on what is available
