If you do analog chip design - you are the highest paid guy in the building - period.That has been true for the nearly 20 years I've been in chip design and I don't see it changing anytime soon.
According to an article in last weeks Aviation Week and Space Technology - you are ignorant.
The value of commercial experimentation on the ISS has taken an unforseen upswing. Real companies are paying Real money to put experiments of different varieties on the ISS.There is a back-log of customers.
I'm thinking the Dragon from Space-X is a nice answer to the Russian suggestion. I also think their minister needs some remedial science classes to learn about the law of gravitiy.... you can't possibly reach escape velocity with a trampoline;-)
First there are really two types of missile defense systems. Those that worry about ICBMs, and those that are "theater" defense.
The US Missile defense system that is costing so much money worries about the first class, i.e. missiles coming from thousands of miles away that are ballistic in nature. We have a limited number of shots for such a defense - and really we're worrying about bad actors like North Korea or perhaps Iran. These guys are going to have a limited capability to throw things at us. So a small number of shots is about right.
These systems can NOT defend against Russia - who can throw several hundred missiles our way.
The theater defense systems are things like the Patriot or the SM3 (I think) that the Navy carries. These have some ballistic defense roll - but their main job is to worry about shorter distance ballistic missiles or air-breathers like the Exocet that was used in the Falklands war. A Hypersonic missile is going to fall into this class and indeed I believe such systems would be out-classed by a Hypersonic weapon today.
Perhaps with the next generation Laser weapons there might be a chance to defend against multiple salvos - but those aren't fielded yet.
I've used codec2 daily in the ghpsdr-alex branch for controlling SDR over Linux remotely.
It is deployed on the Android App glSDR that you can find in the Android Market.
The app provides a GUI with spectrum & waterfall along with Audio from the radio being controlled. Codec2 is used to provide a low-overhead transport that survives the Internet quite nicely.
I've used the app with my 4G phone quite successfully.
Now to the question of latency. When I connect to my own radio with a real-time playback PLUS the codec playback running at the same time, there is a fraction of a second delay - perhaps 100ms-200ms at a guess.
So bottom line is there are real applications for Ham Radio already deploying this technology.
How does this whole thing about LInux be a religion set with the "Cathedral and the Bazaar?" Now I'm confused. How can Linux be a religion when it was developed in a Bazaar?

THE COMPUTER JAM: HOW IT CAME ABOUT By JOHN MARKOFF c.1988 N.Y. Times News Service, 8-Nov-88
Computer scientists who have studied the rogue program that crashed through many of the nation's computer networks last week say the invader actually represents a new type of helpful software designed for computer networks.
The same class of software could be used to harness computers spread aroun the world and put them to work simultaneously.
It could also diagnose malfunctions in a network, execute large computations on many machines at once and act as a speedy messenger.
But it is this same capability that caused thousands of computers in universities, military installations and corporate research centers to stall and shut down the Defense Department's Arpanet system when an illicit version of the program began interacting in an unexpected way.
``It is a very powerful tool for solving problems,'' said John F. Shoch, a computer expert who has studied the programs. ``Like most tools it can be misued, and I think we have an example here of someone who misused and abused the tool.''
The program, written as a ``clever hack'' by Robert Tappan Morris, a 23-year-old Cornell University computer science graduate student, was originally meant to be harmless. It was supposed to copy itself from computer to computer via Arpanet and merely hide itself in the computers. The purpose? Simply to prove that it could be done.
But by a quirk, the program instead reproduced itself so frequently that the computers on the network quickly became jammed.
Interviews with computer scientists who studied the network shutdown and with friends of Morris have disclosed the manner in which the events unfolded.
The program was introduced last Wednesday evening at a computer in the artificial intelligence laboratory at the Massachusetts Institute of Technology. Morris was seated at his terminal at Cornell in Ithaca, N.Y., but he signed onto the machine at MIT. Both his terminal and the MIT machine were attached to Arpanet, a computer network that connects research centers, universities and military bases.
Using a feature of Arpanet, called Sendmail, to exchange messages among computer users, he inserted his rogue program. It immediately exploited a loophole in Sendmail at several computers on Arpanet.
Typically, Sendmail is used to transfer electronic messages from machine to machine throughout the network, placing the messages in personal files.
However, the programmer who originally wrote Sendmail three years ago had left a secret ``backdoor'' in the program to make it easier for his work. It permitted any program written in the computer language known as C to be mailed like any other message.
So instead of a program being sent only to someone's personal files, it could also be sent to a computer's internal control programs, which would start the new program. Only a small group of computer experts _ among them Morris _ knew of the backdoor.
As they dissected Morris's program later, computer experts found that it elegantly exploited the Sendmail backdoor in several ways, copying itself from computer to computer and tapping two additional security provisions to enter new computers.
The invader first began its journey as a program written in the C language. But it also included two ``object'' or ``binary'' files -- programs that could be run directly on Sun Microsystems machines or Digital Equipment VAX computers
1) It was written 15 years ago. Since then we've had 9/11, the Patriot Act, Wikileaks and the NSA invasion of privacy just to mention a few interesting events. So many actors have changed their stripes (Google seems to be a prime example) since this was written. Yet his points are still relevant! If we had paid attention to Dr. Rodgers points then maybe we wouldn't be in the mess we are today. 2) It IS a valley idiot. I stand outside and see two mountain ranges, one on either side... a valley! 3) Since the 1960s this place has been the center of the Semiconductor industry. In the last decade the place has lost most of its manufacturing. Yet calling Silicon Valley 15 years ago was an accurate portrayal.
I believe you are in the wrong place - this is NOT the Microsoft lover's website, but rather the Microsoft Haters website. You must have entered a wrong door some place? Please exit immediately before serious flame damage occurs.
Also note that the tiled interface on Windows 8 is the perfect explanation as to WHY a merging of a desktop and phone environment is stupid. Phones have enough screen room for 1 application, while desktops have screen room for multiple windows. Going to a single window model for desktops is STUPID. Microsoft had an "epic fail" with the Windows 8 tiled interface on the desktop. For that matter it is pretty much an epic fail in the phone marketplace too for the simple fact that it blows chunks!
Whoops - see - you weren't quick enough to avoid flame damage!
Seems to me that Elon Musk may have some egg on his face since he so boldly offered to help out Boeing redesign their battery system on the 787 not to long ago. It seems that Tesla's Li-ion batteries are just as likely to catch on fire! Now - admittedly it took a head-on collision to do that while the Boeing aircraft was just sitting there, but it seems that the Tesla has the same Achilles heal!
I think this very much depends on where the trial happens, UK or US. IANAL - but my understanding of US copyright law - you generally can't copyright lists of things like facts. For instance - from a lawsuit a very long time ago - you can't copyright the information in a phone book. So - if you can get away with the argument that a compilation is merely a list of songs - that is a winning argument for Spotify. I have no idea what the take on this is in the UK - so your mileage may vary considerably.
Being a 30+year observer/survivor of Silicon Valley (and having gone through 3 start-ups) I have to ask - how is this any worse than now that it was during the Dot Com silliness?
For every roughly 10 companies started in the valley - 9 fail. Nothing new about that! It was that way before I got here!
New ideas are vital to the success of the place. Often they are bone-headed ideas? (How do you make money by giving things away for free - the common denominator in the Dot-Com era - as an example!) Others are obvious business models - Gee I think I'll build an on-line auction site (Ebay!) All have been tried - some failed and some soared.
Point is - this is just the normal rough-and-tumbel of Silicon Valley. The author needs to get over himself!
" Plantronics, Borland Software, SCO, Seagate Technologies, and Netflix"
Of these - Borland & Seagate were both located in Scotts Valley NOT Santa Cruz (the city). Scotts Valley is in Santa Cruz County but those are two entirely different entities/locations. Looking at the Netflix website - their Corp HQ is now in Los Gatos on the right side of the Hwy 17 hump!
What is even more ridiculous is the 40% number. Come ON! What about Agriculture. In CA something like 90% or our H2O usage goes to growing things. The power generation is tiny. Then there is the little detail that many of our power plants use ocean water!
And that is ANOTHER bit of my history. Singer-Librascope was headquartered in my hometown of Glendale, CA. I got a summer internship there in 1978, well after the LGP30 days. At that point, Singer-Librascope was entirely devoted to building systems for various military programs. I worked in the R&D lab and picked up a huge amount of experience in a short 3 months. Got to work riding 10 blocks down the hill from home on my moped! To tie this post back into the thread - I got to do some Motorola 6800 programming. Met my first Exorciser development system in the process.
Librascope was going to bid on a device that was to be a submarine released aerial land-mine. They were bidding on delivering the canister that would hold the small missile. They needed to gather data on the characteristics of the canister as it floated up to the surface from the submarine. They wanted to graph depth versus time as the canister rose to the top. Initially we looked at different chart recorders. They were to big/bulky/expensive. Eventually they decided to do a custom 6800 chassis based on what I think was the Exorbus at the time (later to evolve into the VME bus during the 68K era). They plugged a 6800 board from Mot in the chassis along with a pressure transducer board and 32k of RAM. They put a set of switches on the box so the software could read about what it should be doing, and a large battery. The whole assembly fit into the cannister tube. They would pull it down several hundred feet in a lake they had access to and let it float to the top.
When they got it to the top, a program I wrote would play the pressure readings stored in memory out to the cassette port. They would record this onto a cassette for later data reduction. It was a real neat 1 off development effort done in a couple weeks. Lots of fun!
Yep - you could do that for a PDP-8 or PDP-11. Octal makes sense for the 11's assembly! You could read the machine code just about as readily as the assembler.
You had so much room! I learned to program on an Ollevetti Programma 101 in 1971. It was essentially a programmable calculator with 120 possible instruction locations. It used RPN sort of.. and as you went beyond 60 or so instructions you started eating up register storage in chunks until you used up have the available registers with program storage!
The language looked something like
AV ( A label) S (Stop for Input) M+ (Add the Input register to the Accumulator) A This was literally a diamond symbol and meant print the Accumulator V - Branch back to AV..
Your first statement is historically correct, i.e. China doesn't want the entire Korean peninsula under US influence.
I gotta wonder if this calculus isn't going to change soon. China is becoming a dominant economic power all by itself. It has likely past South Korea in that vain on the world market. The US influence is waning at the same rate. Point being - what do they have to worry about having a unified Korea anymore? The US influence there is becoming irrelevant!
Looking at history ( a novel concept I know) you find that indeed this has happened before.
You have a few things coming together that is causing this noise. 1) New leader in NK trying to show his ability to stand up to the West. 2) New leader in South Korea which is a cue for NK to become bellicose. 3) Annual SK/USA war games which NK always uses as a provocation. 4) Even tougher sanctions just put into place.
The US has no desire to go to war, nor does SK. The US is doing what has been doing for 50+ years as far as demonstrating capability but not employing it. The problem is that in the past US leaders have fed the ego of the maniacs in charge in NK by dealing with him. That has NEVER worked! Clinton thought he had peace with NK by giving them food and money. Whoops - Neville Chamberlain moment. It actually is very much like dealing with the local gang trying to run a racket on a business. It doesn't go away until the Gang is thrown in jail. The only ones who can do that are the Chinese or the people of NK.
Slashdot Mirror
So this comes along just as Russia drops the word "Nuclear" to remind everyone that they have them.
Are you naive enough to believe the Russia would bother to show up to negotiate about this?
One also wonders what the people of Ukraine think about such a well timed suggestion.
If you do analog chip design - you are the highest paid guy in the building - period.That has been true for the nearly 20 years I've been in chip design and I don't see it changing anytime soon.
Why don't these guys simply pay attention to a scientific poll that was already run in Eric Cantor's district to see how successful this idea is!
Sheesh!
First time in history that Majority leader of the House has lost his seat- all because he supported some form of immigration reform.
That worked well for him didn't it.
According to an article in last weeks Aviation Week and Space Technology - you are ignorant.

I have a Fedora login prompt on channel 1000 (The Comcast test channel) on my home TV.
The problem is - I can't find the keyboard anywhere near by to try and log in!?!

How does this whole thing about LInux be a religion set with the "Cathedral and the Bazaar?" Now I'm confused. How can Linux be a religion when it was developed in a Bazaar?
I don't get it?
Shouldn't this more appropriately be "RTMP" or Read the Man Page?
