Ok, some more info:
I changed the mapping in tableview.d to:
void setDoubleAction(void __selector(ObjcObject))
[setDoubleAction:] ;
This should be the way to do it. Now in the implementation of the
action:
void doubleClickAction(ObjcObject sender) {
NSLog("double click action") ;
NSLog("the sender: %@", sender) ;
}
This works fine and prints the log: 2014-11-04 10:01:57.967
tableview[9988:507] the sender:
But now I would like to do something with this sender, like I do
often in an Objective-C project:
NSTableView tableView = cast(NSTableView)sender ;
I get a EXC_BAD_ACCESS (SIGSEGV) on this line. Only when I
replace both ObjcObject with NSObject (in tableview.d, the
mapping, and the target action) this cast works. I might be
missing something obvious here.
This should be fixed now in my forks [1] [2]. Note, I've also replaced
the selector syntax, [foo], with a compiler recognized UDA,
@selector("foo").

I'd still want to see much more healthy library ecosystem out there thus simple proposal - poke me via e-mail and I will gladly add any of you projects to the system I have already configured. There is a one requirement though : you must be willing to actually investigate found regressions and report them to bugzilla or workaround in your project. If that sounds OK to you, just let me know" Ironically not a single of few projects I have tried adding currently compiles with a dmd git master - will add more as issues get resolved.

Re: ArrayFire, a GPU library, is now open source
Am I the only one to be left completely cold with the new wave of C++ to GPU libraries (Bolt/ArrayFire/OpenACC) which take back the control compute APIs give? For example this one removes double precision and multiple devices, something that is builtin with OpenCL. These libraries build on the myth that GPU's power can be harnessed without pain, but at one point you have to expose the multiple levels of parallelism that GPU have, use spatial cache locality, etc. This is like, a 60% solution. I am one of the developers of ArrayFire. As we went open source, we removed all restrictions that were put in place for our older commercial version. That is, double precision and multiple device are are part of the open source project. We also support CPU and OpenCL backends along with CUDA. This way, you can use the same ArrayFire code to run across any of those technologies without changes. All you need to do is link the correct library. We used a BSD 3-Clause license to make it easy for everyone to use in their own projects. Here is a blog I made about implementing Conway's Game of Life using ArrayFire http://arrayfire.com/conways-game-of-life-using-arrayfire/. It demonstrates how easy it is to use ArrayFire. Our goal is to make it easy for people to get started with GPU programming and break down the barrier for non-programmers to use the hardware efficiently. I agree that complex algorithms require more custom solutions, but once you get started, things become much easier.

please tell me what concepts you would like to have explained. perhaps I should do a live-stream for Q&A maybe ?

I'm an intermediate level programmer and I'm interested in learning about compilers, so I was very exited when I red your post, and I hope you'll continue. A few suggestions I have: 1. maybe you should pick your target audience, and only talk to that audience. I don't think you need to explain while loops to people who want to learn compilers and you can't teach compilers to people who don't get while loops. 2. talk more about concepts and decision making instead of source - we can follow the source, but there is no obvious answer to "why". So, for example, you go through the source for the lexer, but maybe you should talk instead about the lexer concept- What is it, How will it work, What's the input and output?! 3. it was already mentioned, but it's worth stressing: you should script your recordings. 4. There are a few easy tricks to achieve good quality audio with standard microphones. Maybe if you script your video, and provide the script , the audio will not matter that much. 5. remove the long pauses. we can pause the video if we need more time to process. So, I'm waiting for the next videos, thank you
