"In addition to whatever you decide to do with aerial imagery, I'd recommend just bringing a hand-held GPS unit that you have on whenever you're driving around the city. Then (when you get back?) upload that to Open Street Map and trace the roads. …"
"If my memory serves me correctly from a study I did several years ago, Orbcomm is a store-and-froward satellite system. When a satellite happens to pass overhead, you dump your data to it, it then will drop your data off at the next available…"
"I'm pretty sure that the panda board (looks similar to the beagle board) doesn't work with CUDA, which I believe is nvidia only. Its possible that it will work with OpenCL, but I'd be a bit surprised there too.
When you have an actual nvidia GPU…"

"Yeah, I've had good luck setting up repeated timed shots with my SD1000. Once you read through the instructions on getting it setup, its really easy. I think there are even scripts on the site already set for this, you just need to change the…"
"AtoD on a full video stream isn't trivial. There are some fairly cheap cards for PCs, laptops, usb, etc. that can do it though.
(sorry, this should have been a response to the above post, not at the root level)"

"The problem with encrypting video is that most video streams used are analog. The first step would be to make the video digital, which requires a digital connection (802.11X, cellular, etc) to the airplane. If you have that, then it is simple to…"
"What version of qextserialport's mecurial repo are you using? It appears the latest stuff gets rid of the qextserialbase.h that you're depending on (and moves everything to the ./src subdirectory)."
"Poor man's GPS only works if you have a fix on the exact same satellites at the exact same time (and sometimes not even then).
That said, I believe that the ublox binary protocol has the information you could use to create your own actual DGPS…"

"Another option: Iron Python runs on the .NET framework, if you ran that python code in there, you should be able to call your functions from your existing VB code without having to re-write anything. Its not that much code, but if you get this…"
"For people who want to get into the hardware side...running servos off of pin outs, grabbing serial lines, etc I'd recommend C/C++. But you said you're going to be doing AI research, for something like that, where it is removed from the hardware,…"
"I'm not convinced that it would bring anyone down on us. It could be baked in as just part of the protocol, like some other protocols are using. We could even use parts of the SSL/TLS library (without the complicated public key stuff), then it would…"
"So should we make some plans to add encryption to the data link in our software? From my understanding, using symmetric encryption with pre-shared keys only adds a minimum of overhead. Even if there aren't serious concerns about people hacking into…"
"First, if you don't have previous programming experience, I would recommend that you not jump in and start with Arduino. I know that it would have quickly confused me if I had tried to start with that. Rather, I'd recommend spending some time…"
"Are you new to programming or just C++?"
"I'd like to hear from someone who has worked with simulations software like flightgear, if you're taking suggestions."
"Pekka: You mentioned something about more accurate altitude, do you often see altitudes that are less accurate? I always though that GPS math was completely 3D, and I guess I wouldn't expect one of the dimensions to be different from the others.…"
