As a former military police officer and current concealed weapons licensee, I agree with much of this but dont shoot to kill. Shoot to stop the threat. Never fire a warning shot. Dont shoot in the leg to just injure.

My first response is "Must check out those sites".

I am actually pretty cheap. Good pilots headsets are expensive, but try a pair of regular digital active noise cancellation headsets next time you save $$$ by flying in the back of the cabin. Just putting them on even with no signal in removes all the ambient noise. The difference is heavenly, and if you try it once, you will never go back. If you do not understand what active noise cancellation read http://en.wikipedia.org/wiki/Active_noise_control,

You can get cheap hearing aids for next to nothing. A simple amplifier. If your hearing is damaged to a varying degree at different frequencies, and you want to be able to hear conversations, a better device will be custom made to remap the relevant audio to the right frequencies. This requires customization to each user and advanced digital signal processing. To select human voice, and filter away unwanted noise is also a demanding DSP task.

A good headset for music easily costs $500, and my sennheiser pilot headset costs easily $1000. and that is not customized to me.

Cargo cult science
http://en.wikipedia.org/wiki/Cargo_cult_science

I started reading and just stopped after the first paragraph:
"Spontaneous symmetry breaking is ubiquitous in nature. It occurs when the ground state (classically, the lowest energy state) of a system is less symmetrical than the equations governing the system. Examples in which the symmetry is broken in excited states are common—one just needs to think of Kepler’s elliptical orbits, which break the spherical symmetry of the gravitational force"

Can someone educate me, as this appears to be cargo science:
- How can an "energy state be less symmetrical then the equation for the system". Seems wrong semantically, mathematically and physically?
- How can on state that "elliptical orbits break the spherical symmetry of the gravitational force". How can a simple principle be misunderstood with such pompous nonsense?
- and is the ground state *not* the lowest enerygy state in quantum mechanics as implied in first sentence?

It only gets worse from there.

Hydrogen would have gotten him a lot higher as the molecular weight is only 1/2 of Helium. Also, it would not have wasted a precious finite resource for little gain.

So far it is more of an assembler, but it includes all the "header files" for basic life functions like cell_wall.h, DNA_replication.h, ribosome.h, etc. Each of the header files describes the DNA code for all the needed proteins with all the switches needed.

It is called YADA.jar (Yet Another DNA Assembler)

Right now, the "printer" to get a real organism is cumbersome, but you can run the whole life form as a simulation. If you are Google, you may even grow real humans, and give them all kinds of fun functionality.

My kids have barely seen a DVD, and when I tell them how to play them: (1) go over to bookshelf, and (2) pick a DVD clamshell, then (3) insert into.... they have already lost interest, and are watching the same show on the PC from some preripped source (maybe hulu or whatnot)
Ripping is even more involved, and would likely not happen, and I agree, Rather than ripping, we usually just find a ripped version to download. It usually starts playing in seconds, and is downloaded in minutes. We have a large collection of DVDs, probably over 1000, and they have not been touched for a long time. The DVD player is stored away in closet, and replaced with a PC (the PC was cheaper than the 1080p upconverter)

I will qualify this. If you are a programmer used to an IDE, Arduino sucks. It wes made to allow painters, breadmakers and other artists to make embedded elements, and maybe for a non-programmer, it may be the only (and best) thing out there.

I tried this and dropped it fast. Instead I ended up using Code Composer Studio. It works like a charm for all TI's boards. Try out the 430 development system on sale for $4.30. Great IDE with in circuit debugging and all the other features you are used to, and you are up and running in no time.

Android is also a good choice, powerful, but a little different if you are used to C/C++ insted of Java. Not only for phones but a lot of other embedded devices as well.

BTW, You can get used Samsung Galaxy with a new battery for $100. It is an incredible embedded device, and if you want buy an Arduino device with even a small part of the features, you will pay many times this.
!GHz ARM, 16BG flash, dilsplay,WiFi, Cameras, Graphics engine, xyz accelerometers, maybe gyros. If you need USB master you have to get android 4.0 based device.

The internet is basically a copy machine. I realized this writing an IP stack. It might as well be called the interCopy or the big copy. This word may also make it clear for the distributor that if you put your stuff in the interCopy, it will be copied. That is what the interCopy does. If you do not want your stuff copied, just don't put it in the interCopy.

The (not so big) secret is that most WiFi AP rolls over with 8 or so clients. Only a few manufacturers themselves test their products beyond that, and those work all the way to over 100.
The company selling the test equipment you need is called http://veriwave.com./ You can buy the equipment from them and test all the vendors, or even better, just ask them.

They do of course know, since that is how they test their own test equipment. Problem is that they can/will not tell you because then 1. you would not need to buy their product, and 2. AP mfg would fix their products, and Veriwave would not have a market for their products.

Maybe just do some social hacking to get it out of them.

The board is dominated by the connectors. It looks like 80% of realestate is USB, HDMI etc. They should at least go with small connectors for these features. There are common and small connectors and cables available.

I wrote code for the 802.11b stack, and have gotten a lot of feedback from the test team as well, and here is my 2c:
1. Stacks should handle at least 127 radios on one channel, but most implementations crash with as few as 8 radios alive. Make sure you use a stack that handles many radios. Test your router and your gear (netgear and D-link passed, but check with your current router anyway)
2. Nearby channels appear as noise. If you have many TX on nearby channels, you may not have enough signal/noise ratio. Make sure all gear is MI-MO, and maybe add directed antennas to your router that keep your signal strong in your area.
3. Use channel 14 (you may want to check legality of this in your area) Standard US HW is limited in FW to use ch1-11. Ch 12,13 and 14 is all in virgin territory, and you would be alone at those frequencies, unless of course, you traveled to Spain or Japan or other where you this would look different.
