Actually, maybe I am stupid and ill-informed. There were a couple that had CPU/ABI option as "Atom(x86)". However, it has now been about 4 minutes on my 8 core i7 machine with 6GB of RAM, running nothing but ADT, the emulator, and this web browser and Android is yet to finish booting inside the emulator even running the "Atom(x86)". With VirtualBox + x86 Android images, even from cold boot it takes maybe 40 seconds and if I resume from a paused VM it takes seconds. Now at minute 6 and the ADT emulator still hasn't finished loading. Conclusion, VitrualBox+x86 Android images is infinitely better.

How exactly do you launch the x86 android emulator? When I go to the Android Virtual Device Manager and try every single one of the options in the "Device:" pulldown menu and subsequently try to change the "CPU/ABI:" pulldown menu, the only option is "ARM (armeabi-v71)". So, if such an option exists, they sure make it hard to find (or I am just stupid and ill-informed, so please inform me).

you just have to find the right one (possibly not an easy process). I attended Engineering State at Utah State University and had a lot of fun. It helped me decide between computer engineering and electrical engineering. http://www.engineering.usu.edu/htm/engineering-news/e-state

Why try to optimize Octave for ARM? Instead you should spend time optimizing the {BLAS, LAPACK, FFT, sparse matrices, etc.} libraries on which Octave depends. I don't think there is a lot in the Octave source code itself that would benefit from a lot of time spent on optimization. For the most part, if there are processor optimized version of the aforementioned libraries, then Octave will perform quite well for vectorized code.

I have been contributing small bit to Octave for a couple of years now. I can attest to the fact that the core Octave developers are helpful, do good work, and are always looking for more help. Currently I work on two different parts: an IDE for Octave called OctaveDE (which I am looking for more help on, but is more UI work than math work) and I am rewriting the image reading and writing routines to be Matlab compatible. There is also a lot of OpenGL work going on implementing a faster plotting backend as an alternative to GNUPlot. Because Octave is ofttimes in "Matlab catchup mode", any help would be greatly appreciated and you would be given direction on the best way to contribute early while you get used to the code base and the way the core developers work.

Some people buy pre-made parts, others head to the machine shop to make custom parts, and some just go for show. Whatever kind of pinewood derby fanatic you are, I think Cub Scouts and it many variants who run pinewood derby races should promote the car building as a way of encouraging math and science in the younger generation. There are a lot of science-y toys out there (Lego Mindstorm, Construx, others), but how many of them let a kid sit down with raw materials and try to figure out how to eke out a few milliseconds less than their competitor."

Education

+ - Teach science and math through the pinewood derby->

jpswensen writes "Several months ago, someone posted on AskSlashdot about tips on building a fast pinewood derby car. We weren't finished with our video, so I didn't want to post then, but we now have it completed. There are several videos out there that simply give tips and techniques for building a car, but we took a slightly different approach. Our video is first educational (about 60 of the 110 minutes) and secondly a "howto" on building a car and simple track for home. The movie came about because of the experience my collaborator, Dr. Scott Acton, had with his son. In fact, they spent one summer building several pinewood derby cars and doing many of the experiments shown in the video.
<rant> Now is where I talk about how we need to find more ways to get young kids interested in math and science and I think videos like ours and programs like FIRST Robotics and others are exactly what we need more of. So, check it out, buy it if you like, and promote math and science to kids in whatever ways you can find. </rant>"

As for whether you own your own ideas or not, many companies make you sign away patent right for anything you come up with (while working for them, whether on the job or not) that is related to their business interests. Sometimes very skilled or well-known people can weasle their way out of clauses like this, but for the most part you probably signed away your right to patent tech stuff when you signed you offer acceptance letter. go read it.

No amount of careful planning will ever replace dumb luck.
