digitalmars.D - Gathering info for D/Embedded presentation

After some gentle preachings I have been asked in my company to 
prepare presentation regarding D usage in scope of embedded, 
kernel-level development and mobile devices. I am quite starving 
to find good project examples for D2 though ( most stuff I am 
aware of is D1 ) and do not have enough time to write some from 
scratch. Any suggestions here?

Regarding mobile development - I remember a thread some time ago 
regarding Android + D2 that I can't find anymore. What is current 
state of affairs?

Any general advices about D2 features and drawbacks to bring 
attention to are also welcome.

You can have a look at this guide:

Ye, also have finally found it and related thread:

Thanks anyway.

I'm also curious if druntime can be made compatible with bionic
because now I have to experiment with using a chrooted linux on my
phone to test some D applications.

1) Do you consider garbage collection to be an issue in embedded 
programming?

2) Are you dealing with hard timing constraints where garbage 
collection could be an issue?


I would love a copy of your presentation

================================================

I think the XOMB  operating system project was a D1 project not a 
D2 project.
but this may be of interest:

http://wiki.xomb.org/index.php?title=XOmB_Bare_Bones

The XOmB Bare Bones distribution is a minimal 64 bit OS written 
in D, distilled from the main project by wilkie and Steve Klabnik.

1) Embedded programming today means freaking lot of environment 
from microchips to custom hardware server clusters :) Sometimes 
it is an issue, sometimes not, but that is definitely a thing you 
need to remember about all the time.

2) Yes.

I have had a similar questions from my colleagues, that is 
exactly why I was asked to research this topic in detail. I ll 
share it when it will be done, but that won't be any soon.

XOMB is exactly on the D1 projects I was referring to, when was 
asking if any more modern analogues exist :)

I would have a look at real time JVMs/AOT compilers, as they show 
the current state of the art in GC enabled systems targeting 
embedded devices.

In case you don't know any:

http://www.atego.com/products/aonix-perc-pico/
http://www-01.ibm.com/software/webservers/realtime/description.html
http://www.research.ibm.com/people/d/dgrove/papers/emsoft05.pdf

Eventually D's GC will be comparable to those.

Although it is not D, have a look at BlueBottle, it is 
implemented in Active Oberon, with only some hardware glue in 
Assembly. Fully usable desktop system implemented in a GC enabled 
systems programming language.

http://www.ocp.inf.ethz.ch/wiki/
http://www.ocp.inf.ethz.ch/wiki/Documentation/WindowManager

The system is since the late 90's used at ETHZ.

Something like this would be fully possible with D, even better.

Having been a user of the first generation of this OS (Native 
Oberon) has convinced me that OS development in GC enabled 
systems language is possible, even thought there are some cases 
where it might not make sense. I wouldn't want a GC 
stop-the-world in a plane computing system. :)

Sorry if my post is too off-topic, just wanted to raise some 
points you could somehow use to pimp up D.
