Re: Turning it into a geniune coin-op machine

I think one of the goals of the pi is the exact opposite of what you're trying to do with that SWF there.. The way forward for you and your friend is not to make the flash run on the pi by implementing all of the intermediary layers , but to raise your skills to the extent where these layers are eli...

Raspbian is great and you will have excellent synergy with any other Debian-based systems you may be running. If you're looking to set up a server then don't get sidetracked by desktop performance.

Re: Joining Pi's for emulation

What are you planning to emulate? You will find it very difficult to "cluster" a number of pi's together, and running an emulation would probably not be very efficient either due to the overhead involved. Speed would suffer. That said, it's interesting to know exactly what you would be looking to em...

Re: What else can I do with a pi?

Been thinking of making a hatchery, to use for hatching bird eggs. The pi could read and control hatchery temperature and humidity, maybe even rotate eggs for X amount of days after incubation. A temp/humidity sensor and a few relays could be all you need. Dave Driesen Linux dev and oldskool elite

Re: Is it normal for the RasPi to be this slow?

I've always been quite impressed with the speed of the Pi.

Hi, The Pi uses a subset of OpenGL known as OpenGL ES (OpenGL for Embedded Systems). Make no mistake, OpenGL ES is very powerful. However, GLX is not supported on OpenGL ES; GLX is purely an OpenGL extension to X. (The OpenGL ES "equivalent" of GLX is EGL. I've not gotten around to meddling with it ...
