Yep! If you're prepared to forego the arduino libs and use the native Atmel SDK, you can use AVR Studio 5 which includes a simulator/debugger and is built on VS2010 shell (doesn't require VS2010 license). You have to use avrdude yourself to squirt the compiled results to the arduino, but it works a charm. Just get a copy of the relevant datasheet and you're off...

speaking of machine models, anyone care to explain pointers to members of classes with mutiple virtual bases? or what happens when an exception is thrown?

  • callstack
  • locals
  • watch
having any one of these open when stopped at a breakpoint brings the IDE to a crawl (see the visible lag when resizing the IDE.)
interestingly enough, the autos window doesn't exhibit this behavior.

in the future, suppose:

- you have a C++AMP compiler that targets direct3d v12 which has more capabilities that v11.

- you want to write code that targets the version of direct3d that's available on the user's machine, but you want to take advantage of the new d3dv12 features if available.

 

it would seem to me that there's definitely a need for versioning there, both at compile time AND at runtime.

 

will "restrict(direct3d)" always mean v11, if so how will we restrict to v12? if not, won't that break existing code when switching compilers?

who writes/distributes the AMP runtime components? are they a standard OS component (.so/.dll), or are they a .lib baked in at compile-time? how will these be serviced (apropos GDI+ nightmare)?

will non-Microsoft, direct3d-targeting compilers use Microsoft-supplied direct3d runtimes, or will they have to write their own?

will we be able to include different versions of our restricted functions for different versions of direct3d? how will this work, since the override would have to happen at runtime?

Hey Charles, wich version of video you use on smoothstream? even when i go fullscreen it looks aliased, like the Medium Quality WMV (I have a 10Mbps line, but for international link It sometimes drop to 1Mbps, depending the destination server).

sorry for going OT, but I'm also seeing very poor quality in full-screen or zoomed browser. I have a fast connection, and I was able to stream the 'High Quality WMV' without dropping frames. It would be great if you could enable smooth-streaming for some of the higher bitrate streams.
