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

https://lichess.org/account/passwd gives no feedback in that case, aside from keeping the form fields filled in

there should be either some client side feedback, or added feedback for the server side validation

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

gatling.sh ....

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)?

steps

Global / onChangedBuildSource := ReloadOnSourceChanges

problem

It's developer specific preference, and we can't put it in global either because of datatype.

expectation

If there's a system property for this, we can use that as a default.

$ sbt -Dsbt.build.onchange=reload
$ sbt -Dsbt.build.onchange=warn
$ sbt -Dsbt.build.onchange=ignore

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

➜  ~ dotr
Starting dotty REPL...
scala> type Color = "top" | "middle"
// defined alias type Color = "top" | "middle"

scala> def test(color:Color) = println(color)
def test(color: Color): Unit

middle

scala> test("middel") 

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).

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

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
