Announcing Mecca
Hello everybody,
I am very happy to announce that Mecca version 0.0.1 (sorry, no more
zeros than that) is now officially available. You can get the source
code at https://github.com/weka-io/mecca. The API documentation is at
https://weka-io.github.com/mecca/docs.
Mecca is a run-time support library for fibers management, as well as a
few useful containers and libraries.
At this point in time, a getting started tutorial is still not
available. Instead, I will post this small program for an echo server.
It should give you a hint what APIs to check out with the documentation,
so you can expand your search:
import core.sys.posix.sys.socket;
import std.algorithm : move;
import std.functional : toDelegate;
import mecca.log;
import mecca.reactor;
import mecca.reactor.io.fd;
import mecca.reactor.io.signals;
enum EchoerPort = 31337;
int main()
{
theReactor.setup();
reactorSignal.registerHandler(OSSignal.SIGTERM,
toDelegate());
reactorSignal.registerHandler(OSSignal.SIGINT,
toDelegate());
theReactor.spawnFiber!listener();
return theReactor.start();
}
void termHandler(ref const(signalfd_siginfo) siginfo) {
// Signal handler, but any non-yielding operation is safe to call
from here.
theReactor.stop();
}
void listener() {
auto listenSocket = ConnectedSocket.listen( SockAddrIPv4.any(
EchoerPort ) );
listenSocket.setSockOpt( SOL_SOCKET, SO_REUSEADDR, 1 );
while( true ) {
SockAddr clientAddress;
auto clientSocket = listenSocket.accept(clientAddress);
// The next line's toString is the only reason we can't annotate
// listener as @nogc.
INFO!"Received new connection from %s"(clientAddress.toString());
theReactor.spawnFiber!echoClient( move(clientSocket) );
}
}
void echoClient(ConnectedSocket sock) @nogc {
ssize_t dataLength;
do {
char[4096] buffer;
dataLength = sock.read(buffer);
sock.write(buffer[0..dataLength]);
} while( dataLength>0 );
}

I think you should talk to them and explain what an asset these recordings are to dlang, and that we cannot let them be jeopardised by WiFi outages. +1. I was expecting to watch Walter's presentation, and now I would say this is a big failure for them. Come on, this not a new event! In this day and age with all the cameras around us, if they really lost any content they should stop doing this. Sorry if I'm too harsh, but this is totally unacceptable. It's not a problem. Walter can redo the talk from his basement and upload it to youtube.

Don't worry, you didn't miss much. You're better off just reading his blog post, as Walter keeps his keynotes light on tech: https://dlang.org/blog/2017/08/23/d-as-a-better-c/ While the post covers slightly different material, it gives the idea.

Was it lost? I believe the lost video is only from the morning of the first day. Andrei's talk may simply not be accessible in the archived livestream anymore, as Nemenja says, but there's no indication that it was lost.

Re: Tilix 1.7.9 Released
On Sunday, 29 April 2018 at 14:01:10 UTC, Gerald wrote: A new version of tilix has been released. For those not familiar with it, Tilix is a terminal emulator for Linux written in D using GTK. The list of changes is available here: https://gnunn1.github.io/tilix-web/2018/04/28/release-1-7-9 As always, I'm always looking for people who are interested in contributing, PRs welcome. Finally a big thank you to Mike Wey who has continued to work on and evolve GtkD. Working on libraries is often behind the scenes work that doesn't get the appreciation it deserves. I was struck by a recent reddit post on the gnome shell memory leak which involved C and javascript, it mentioned how difficult it is to merge two different memory models. Mike has managed this with aplomb in terms of integrating the Gtk reference counting into D's GC. So thanks Mike, your efforts are much appreciated! I used it for more than year but after switching OS / re-installation I used the OS's terminal for a while. Now I'm back on Tilix. I am delighted. It's more fun this way.

As Bastiaan Veelo wrote it appears that something went wrong with the youtube recordings. Hope this gets resolved and at least the upcoming talks, if not all, will be available. Yes, unfortunately some of the videos were lost. We should be good from here on out.
