As many of you know, the Raspberry Pi Foundation announced the Raspberry Pi 2 Model B (http://www.raspberrypi.org/products/raspberry-pi-2-model-b/) having the same price and identical form factor as the Model B+ but with four ARM7 CPU cores and a gigabyte of RAM, providing twice the memory and roughly six times the CPU power of the prior models, at the same price.
FlightAware will provide and support PiAware for the Pi 2 as well as continuing to support the existing Pi 1 Model A, B and B+.
I’m excited about the Pi 2 for a few reasons:
dump1090 will not super noticeably slow down the machine like it does now
It’s powerful enough and has enough memory that the graphical desktop environment will have fairly decent performance, which could really open up some possibilities
Time-consuming software and package builds will go a lot faster (something I’m looking forward to)
From what I’ve read it will require a different system image, which means we’ll probably have to provide two SD card images. Not ideal but not a big deal.
Also initially the same userland will be provided for both by using the one compiled for the slower and less sophisticated ARM11 CPU in the Pi 1 (yeah I know, why is 11 < 7?) but I think recompiling CPU-hungry dump1090 specifically for the Pi 2 is likely to yield a nice performance win.
More speculatively, there are some capabilities in the new chip and possibilities for leveraging the GPU for general computation that are very interesting.
Anyway, we haven’t received our hardware yet, and it is in fact back-ordered, but I expect we’ll have Pi 2 SD card images by the end of the month at the latest.
Thanks for playing…
