Issue description

In writing rust zmq bindings for tokio, the question came up about when zmq_send and zmq_recv might return EAGAIN when passed the ZMQ_DONTWAIT flag in a multipart message. The implication of the high water mark documentation is that it will only return EAGAIN on the first part of the multipart message, but I couldn't find it explicitly stated anywhere that this

Not sure if this should be an issue but I was reading the docs and then followed the link to the example's code on github and noticed that they differed. Which is considered more up-to-date (and thus the best practice)?

I have some code that is throwing an exception in a post-park action (i.e. inside the handler passed to parkAndSerialize). Quasar silently eats this exception in RunnableFiberTask.onException(). It's really confusing to have the framework eat exceptions without any kind of logging or error printing at all.

I suggest changing this code such that if the exception isn't handled here, it's either re-

I'm new in Akka and trying to self-define a dispatcher in my code. But there are so few akka dotnet examples available, and most of them are using config files..
Could I create a dispatcher in code, i.e., like the follows:

public Dispatcher myDispatcher = new Dispatcher(new DispatcherConfigurator(ConfigurationFactory.ParseString(@"akka.actor.default-dispatcher { type = ""Akka.Dispatch.TaskDisp

Gamma correction is among the things most often done wrong by graphics programming novices. It's almost as bad as missing scene-related color transforms and linear volume sliders in the average video game. The code example in the readme should definitely mention to adjust.Gamma(img, 1/2.2) before doing any color mixing and adjust.Gamma(img, 2.2) before saving back to file (for as long as _bild

Hi, I'm not sure if more platforms are interesting to you, but I've made a slightly more complete implementation of padding a struct to the cache line size here:

https://github.com/tinco/cache_line_size

I got the information on the cache line sizes from the Go compiler repository, so I'm pretty sure these are correct for all platforms Go runs on, which is a whole bunch.

It's not easy to understand what the code generators under jctools-build are supposed to do. I think one or two phases documenting their goal would be useful.

I am proposing to document these classes:

  • JavaParsingAtomicArrayQueueGenerator.java
  • JavaParsingAtomicLinkedQueueGenerator.java
  • JavaParsingAtomicQueueGenerator.java

ZTransducer is an effectful chunk processing function, and thus forms an arrow. We should add the following combinators on it:

  • zipping: (ZTransducer[A, B], ZTransducer[A, C]) => ZTransducer[A, (B, C)]
  • racing: (ZTransducer[A, B], ZTransducer[A, C]) => ZTransducer[A, Either[B, C]] looks problematic to implement currently
  • both: `(ZTransducer[A, C], ZTransducer[B, D]) => ZTr
