I totally agree. Everyone here is obsessed with H1B's and seem to equate it with outsourcing to Bangladesh. No-one seems to consider that talented first-world people might want to work in America.

Often Americans ask "how can I emigrate to the UK"? Well the answer is you basically can't. Tight immigration controls aren't so great then are they?

developing a cubesat reportedly runs from $25-50k

Yeah in engineers salaries, solar panels, machining work, testing, etc. The cost of the computer is only a part of that.

Cell phones are perfect because they include a compass, gyro, camera, etc. A LOT more than just an ARM SoC.

The hardware in a phone doesn't cost anywhere near $25k. In fact buying the parts separately is probably cheaper than most phones (because you can miss out the screen, 3G, GPS, wifi, etc. on a satellite). Plus if you build it yourself you will save weight and have more flexibility. Something like gumstix combined with and one of invensense's new IMU chips would be much better than an Android phone. If you're spending $40k on the launch, why pinch pennies on the hardware?

The area where android phones really *are* great is UAVs! You basically just take a cheap android phone. Add an IMU, and PWM output board and you're done, and have 3G, GPS, wifi, cameras, for very cheap (£50 or less).

Manufacturers make panels with specific pixel densities. They can then cut those panels to a number of different sizes in order to achieve a number of different resolutions.

Just to be clear (maybe you knew this), but you make it sound like there is a huge sheet of "screen" and they cut different sized rectangles out of it to get the different displays. That isn't the case at all. They screen sizes have to be chosen before they start doing anything.

Haha if you think blender can do CAD, you've obviously never used real CAD software. I wish it weren't the case, but currently nothing (including FreeCAD) comes even close to Solidworks. Trust me, I have used all of the following programs:

* FreeCAD - Yeah, not useful.
* HeeksCAD - Sadly also not useful.
* Solidworks - Amazingly amazing. But Windows only, and there is no way to get it for a sane amount of money other than piracy.
* Pro/Engineer - Very good, but a shit interface (Motif!). It used to have Linux support but recently they stopped that and I think updated the interface. And it's called something else now. But if you're going to use something on Windows I don't see why you wouldn't use Solidworks.
* QCad - This is worse than a pencil and paper. I am not joking.
* Sketchup - Yeah, not very useful because it isn't parametric. Once you have set the length of something you can't alter it precisely. Seriously if you've ever used Solidworks or Pro/E you'll be tearing your hair out.
* Creo Co/Create Modelling Personal Edition Lite Free... Ah fuck it. I can never remember the (retarded) name, but this is the only decent free CAD software in existence. Unfortunately it is Windows only (doesn't run in wine), and also non-parametric, so not very useful in practice. (But it is still miles better than Sketchup.) Actually I think they sued sketch-up (or vice versa) because they use the same extrusion interface.

By the way, don't be fooled by fancy screenshots of models like this one: http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=File:Screenshot-gcad.jpg
