We use sbt-dynver to set the version for the Play project based on git tags.
E.g. when you run sbt in the Play project folder you will see:
// If you haven't you need to get the Play framework source code
git clone git@github.com:playframework/playframework.git
cd ./playframework
// You are in the master branch now, from which we want to rele
Provide a way to copy a study chapter's PGN, without having to download it. The analysis page has this functionality already. It can perhaps live below the FEN text box:

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

We could consider adding some random generator functions to Gatling Expression Language, such as:
- random numbers (int, long), possibly with a range
- random UUUI
- random alphanum Strings with a length
Note: as this is a feature, it has to go in a minor version, which we release ~3 months.
Implementation would be similar to what we do with currentTimeMillis
.
Performance is a must, so I
unhelpful error message for ValueOf[N] when no singleton available for N (bounded by singleton)
Compiler version
3.2.0-RC1
Minimized code
import scala.compiletime.*
class Vec[N <: Int & Singleton] :
private val xs: Array[Double] = Array.ofDim[Double](summon[ValueOf[N]].value)
Output
No singleton value available for N.
Expectation
My expectation is that the Singleton
bound makes ValueOf
realize that N
is a singleton. But I am
Show[Throwable]
I just came across the fact that a Show[Throwable]
exists.

import Scalaz._
, one needs toimport scalaz.std.java.throwable._
- 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)?

Description
It looks the Polynote doesn't support to configure Scala REPL like other notebook product.
For example, jupyter notebook support to configure Scala REPL such as
interp.configureCompiler(_.settings.outputDirs.setSingleOutput(replClassPath))
interp.configureCompiler(_.settings.Yreplclassbased)
Some configuration is hard-coded such as settings.Ydelambdafy.value
is s
As part of a pending PR for Issue #2750, I did a due diligence check to see
if that bug existed other places where a file was opened.
java.nio.Files#readAllBytes
opens a file fcntl.O_RDONLY
so it
does not have the bug described in #2750, but it does have
the bug of not checking the return from fcntl.open()
.
One would have to check the Java 8 documentation for readAllBytes

Problem:
The current log will output something like val_function_0
while it should be val_mean_squared_error_0
.
Solution:
"val/{}_{}".format(type(metric).__name__, i)
use the name of the type of metric
(metric is an instance of torchmetrics.metric.Metric
so the type of it is function
), that's why the output looks like val_function_0
. It should use the name of the metri

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.
