Beautiful and cool slides, as always, Marcus.

Yes the Pharo community did a lot of work this passed year, and the future looks really exciting !

It feels good to be part of this.

Thx for sharing.

Sven

It's so exciting to see all the current and future advances listed together - what momentum!

I should release my annotated version because it explains the vision behind each item…

Should fish it.

Nice presentation!  I look forward to Stef's annotations and the video.

One thing jumped off the page: the intersection of OpenGL, Sig and NativeBoost.  It says "done on Windows" which I *hope* means that Linux and Mac are planned???  Being able to embed 3D worlds in "normal" desktop software would be huge (virtual reality/visualization,  simulation, etc.).

Question: does this suggest that NativeBoost should advance in the FFI roadmap?  AFAIK, I do not care whether FFI, Alien or NativeBoost becomes the first complete FFI solution for us.  I mostly want to see callbacks and some level of multi-threading.  It would be nice if existing FFI method definitions continued to work, but that's negotiable.  

On threads, the most important objective is to be able to call into a library without blocking the entire image.  If callbacks are not possible from such a function, I could learn to live with that - it's more than we have now.  If allowed, I would expect that callbacks would be limited to the calling Process in some way.  One could/should use queues, semaphores or deferred actions to make things felt in the UI.

I will let you guess.

The idea is that we would like in january to have one ffi fully working (callback, threaded...…..)

Stef,

My guess will be an optimistic one :)  It is of course non-binding, but that sounds great.  With Sig on the job, probability of success is high.

Re FFI and threading, Eliot described some very interesting ideas a while back; if you are undecided on how to proceed, it would be worth reading his posts on the subject.  Callbacks would be most welcome.

Loosely related to all of this is handling arrays of doubles in FFI, which brings up alignment.  I know I am not doing this stuff correctly, but I have been getting away with it, and it is crucial to putting GSL (or other libraries) to work.  I'll start another thread on the topic.

Bill
