There is indeed a separate higher resolution encrypted feed for the military. Encrypting for civilian channel use is very impractical as many many devices lack the ability to update keys (no network connection). Encryption also burn clocks and batteries. With billions of devices being made all over the world by thousands of manufacturers keeping the keys private is unrealistic.

Sad to say, I had a real world need to calculate the number of HDDs that will fit in a 747-400F. And yes, it does beat the a station wagon and even fiber for average bandwidth hands down (excluding reading/writing the data). And no, nobody asked how much the data weighed.
I could not agree more about what unclearchannel consolidation has done to homogenize our community media. Of greater risk is the destruction to our communities' resiliency. It used to be that broadcast radio was a critical infrastructure in times of disaster. I remember ("kids, get off my lawn") power and towers going down and the station techs/DJs and maybe a ham driving out to back-up transmitters winging it live and helping to coordinate communications and resources when needed. I assume these days most of these corporate stations are just an unmanned transmitter attached to DSL line without a local tech to be seen in the same city. At least we do have NPR with real engineer, tech and talent that knows the phone numbers for local resources.
The fact that the handset vendors are selling $k phones without such a simple, basic lifesaving resources as an FM receiver + weather radio (~162 MHz) is criminal.
Then again, I gess we are all just consumers so who need real community.
Wow. So much to say on this I don't know where to start. In embedded system development, where you are co-developing HW/FW/SW, there is such a mismatch between worlds that I've yet to see a good way to manage it. HW often has three+ month iteration cycles so it is a complete mismatch with software cycles. The only PM magic I've seen is Design Reviews Up Front (DRUP). For example, after the HW folks have rough block diagrams done in the first week or two, have a deep design review with ALL parties (ME/FW/SW/Mfg/Buyers/Service/etc) BEFORE they start detailed schematic design then have another DRUP before layout. This is the closest thing I've seen to continuous integration in embedded systems. Far too often I've seen the EEs show up for the only design review with finished schematics three days late for sending it to layout only to hear from the FW or SW team that the CPU they've chosen will not work. Of course by then it is too late then to fix the problem. The SW team is usually off developing on an overpowered development board (or worse, PCs) that has no relation to the real target so the SW will never fit the real product. The other big review fail I've seen is only inviting your discipline to your design review (eg., only EEs to HW). Inviting only your tribe to only a final review is only an exercise in "how can our tribe improve for next time," not a way to improve this product. I still do run things scrummy, but tend to be very lax on estimates, etc.
I seem to remember that someone used to make fridges that had a back door that went against a cutout in your outside wall so the milk man can put your milk in your fridge without entering your house. Also, some houses had little (12" x 12") double doors in the wall that the milkman could put our milk into and you could take it out from inside the house. We are talking decades ago when there were such a ting as milkmen rattling down your street at 5AM delivering milk. At they used wireless communication - you just put a note in an empty milk bottle asking for more milk. Oh, and yes they delivered in glass bottle that were washed and reused instead of making more trash. Never mind, it was a galaxy far, far away...
Perhaps I was not as clear as I should have been: if a business negotiates a custom sweet-heart deal just for their business that other business at that locality do not have access to then yes that should be seen as income and taxed. If on the other hand a company chooses to move to a low services/low tax location and is taxed at the same rate as other businesses at that location then good luck to them. They'll need it finding qualified workers.
Is there a forthcoming article by a western new source about to pop? Get the spin out early and make it look like it is OK because "everyone is doing it." Just read Wikileaks's editorial comments: "suggesting a similar state-funded mass surveillance program to the one utilized by the U.S.'s NSA or by GCHQ in the U.K"
At large companies, there are:
1) large incentives (several $K) to engineers to get a patent.
2) Incentives to managers to have their teams to get patents
3) Billable hours for outside patent council to file regardless of how questionable value that patent may be
4) Pressure from the board to CxOs have more patents than IBM
5) Easily fungible value as very, very few patents are ever licensed.
Good point about the softer side of the network from the Portland 911 system event. On a larger scale, all it took was one a misplaced if/break statement to prove a "trivial" Unix patch can bring down even the most robust network. ( As a C programmer I have to take issue with the article blaming the compiler and not the programmer and their test tools/environment, but then than's just my world view).
Moof,
Hams are perhaps a little too good at getting press coverage relative to their impact. I would agree that Ham radio is falling by the wayside, due to the ubiquity of cell phones. Without a doubt cell phone are ubiquitous, easier to use for the general population and provide much greater and richer range of services. Indeed cell should be the perfected initial line of communication. This wonderful cell technology is predicated on a brittle infrastructure of cell towers.
I happen to live in the mountains along a the only east bound interstate out of Seattle which normally has great cell service. Even though I am only an hour away from Microsoft and Amazon HQ, several times a year we have weather events the close the roads and knocks-out power that results in loss of land, cable and cell service. Due to our continued power disruptions the cell providers have bolstered their back-up power, but power still runs out and we lose all "consumer" communication. I shudder to think what would happen in Seattle when the overdue big earthquake hits. We have another mountain pass that has had landlines taken-out by a 2015 landslide and is still waiting for landlines/Internet and local towers to be restored. This pass currently only has one distant cell tower that provides only weather dependent dodgy connectivity.
The old AT&T infrastructure (circa 1950/60) was designed to even be replaceable after a nuclear attack. Go look at an old Ma'Bell microwave tower site. They were literally concrete bunkers. I just don't see modern quarterly profit driven cell providers building to survive 500 year events. Resiliency requires more and better fall back options. Infrastructure seems to work great until they suddenly don't.
To a great extent this is why ham radio is still around. I applaud folks good intentions to jump in and help, but counting on cell towers to stay up is courting a bigger disaster. There will be storms/earthquakes, etc that will take down the cell towers, the fiber that connects it, the electricity the supports it,and the diesel supply chain that keeps back-up generators running. Ham radio frequencies can reach hundreds and even thousands of miles to areas outside of an impacted area and are often the only line of communication in a disaster. We also need to enable the FM receivers that are built into modern cell to support broadcast of "critical, need to know information."
One of the most overlooked, yet most significant innovations of the early 20th century might be the Post Office’s decision to start shipping large parcels and packages through the mail. While private delivery companies flourished during the 19th century, the Parcel Post dramatically expanded the reach of mail-order companies to America’s many rural communities, as well as the demand for their products. When the Post Office’s Parcel Post officially began on January 1, 1913, the new service suddenly allowed millions of Americans great access to all kinds of goods and services. But almost immediately, it had some unintended consequences as some parents tried to send their children through the mail.
“It got some headlines when it happened, probably because it was so cute,” United States Postal Service historian Jenny Lynch tells Smithsonian.com.
Just a few weeks after Parcel Post began, an Ohio couple named Jesse and Mathilda Beagle “mailed” their 8-month-old son James to his grandmother, who lived just a few miles away in Batavia. According to Lynch, Baby James was just shy of the 11-pound weight limit for packages sent via Parcel Post, and his “delivery” cost his parents only 15 cents in postage (although they did insure him for $50). The quirky story soon made newspapers, and for the next several years, similar stories would occasionally surface as other parents followed suit.

Yes, many "civilized" folks who never walk more than 2 feet to their car could not run to save their lives. However, most nomads could probably make a good run for it. Probably a bigger issue is heat. How fast would the T-Rex over heat. The ability of many animals to cools is often the difference between life and death. Cooling is what makes humans such a great predictor. Many prey animals can out sprint us, but few animal can keep running for several hours.
“AI is an algorithm in a clown suit. It’s less predictable, it’s more fun, and it comes without a 30-day, money-back guarantee.”
Sorry, but what is being touted as AI ain't either. What is being pushed today as AI is little more than an unbaked solution to a badly under-determined system of linear equations.
