If these towers are not registered with the FCC, then what would happen if one possibly fell over?
Nothing. Like a tree falling in a forest with nobody around to hear it. Besides being factious that FCC no longer does enforcement but probably get attention from OSHA or local planning dept that issues permits.
reminds me of "free Comcast" of leaky cable boxes. Some years ago when Comcast had analog, and when watching amateur television on 421.25 MHz and 427.25 MHz I find certain parts of town being able to see Fox CNN on cable these freq (which are CATV Ch 57 and 58). Though all digital now but there are still lots of leaky boxes around though not sure if stations worth watching.
I still have comcast but only watch a few channels (I pay for hundreds I don't watch which is like paying monthly payments for a car I only drive 3 days a month). Talking with a friend who said there is about 100 OTA TV channels here in SF bay area. Not that all those channels interest me, but when he said OTA HD looks much better than Comcast which compresses the video (gotta fit all those channels through the coax pipe). He further described watching KQED OTA HD channel on oceanic life on a big screen (it was spectacular), then switched to same channel from Comcast. It was not as good. Then my comcast bill is a few dollars more (it seems to keep going up and promoting more football which I don't watch at all. was it the Cleveland Lakers that won the Superbowl?).
Maybe it's time to cut the cord from Comcast, my last month!

I remain puzzled by the point of your post. [snip] The politics not the physics of the US space program more or less preclude that.
I probably jumped discussion too much, it refers to some people advocating commercial space that "it is easy" just like airplanes, emphasizing it's just a little harder. Actually it is difficult getting to LEO, SpaceX has made it lower cost when compared to "Arsenal Space" but still there is no cheap. So don't expect in 10 years from now going to LEO will be as straight forward as driving to Pittsburg.
We will have to see what next 10 years will bring, 10 years ago nobody expected us to be in a situation like we are now.
If the Soviet Union had managed LEO or the moon, do you think they would have not used it?.
Of course they would use it, like they used Sputnik and Gagarin to show superiority of communism and those were countered with NASA and Apollo. When these were successful, they were reduced (we abandoned going beyond LEO, and NASA struggles). Look at current "threats" which are not from USSR so the agency with one less A than NASA gets unlimited budget and authority, and can skirt the US Constitution.
And rather than continue to do something that hasn't worked in around four decades (and really, the Space Shuttle and the Apollo programs were just money sinks) maybe we could look at things that do work, like SpaceX's approach?
Apollo succeeded because the politicos (those in power) realized if Soviets land on the moon first, they will plant the Hammer and Sickle flag on the surface that will enslave the world in Communism (not really but that's what they thought). So with that in mind, do whatever necessary to prevent that from happening otherwise their goose is cooked (strong motivator like 25 years before when threatened by Nazi Germany and Imperial Japan).
Then after what next? Shuttle was left over from more ambitious missions of orbiting stations, lunar bases, mission to Mars, etc. And it could have easily not happened. see Dale Myers on MIT OCW video in 2005 when he said at time it looked like last HSF by US would have been the Skylab missions, Apollo-Soyuz was not scheduled at that time (sorry too lazy to get link but it's on youtube). Nixon realizing many people laid off in states with lots of electoral votes (CA and FL) so give them a big program to continue, in 1972 he said to OMB stop objecting to NASA plans for Shuttle and approve it.
Fast forward to 21st century and progress made by SpaceX and others is result of wealth inequality. Few billionaires have some billions they can put into to what they want rather than meeting political objectives (war, votes, whatever).
Argue all you want, you still have to deal with the tyranny of the Rocket Equation.
uhmm, component video is not same as s-video (or correctly should be called Y/C). Component has three cables (Y, Pb, Pr), Y/C has two cables (Y, C). What drives me nuts is Y/C has some improvement over composite but uses crummy cheap connectors. Composite lives on because works great in an industrial environment with a single coax and locking BNC connector. Of course it also has the RCA connector which is more rugged than that crummy DIN connector used by Y/C.
The bigger problem is that the slashvertisement has almost as much information as the linked page, most of it word-for-word.
veering OT, I've been surfing internet on video systems (HD, bitrates, modes, codecs, connectors, etc). Your quote reminded me why so difficult getting good info on the web:
"Yet today you have some manufactures creating completely phony websites that are supposedly written by former employees of the company, who are supposedly letting you in on 'inside secrets' of the companies new equipment, only to find out that it's astroturfing. Astroturfing is when a company tries to disguise their sales agenda as an independent public reaction to their product, in this case with a phony website with covert disinformation. One such example of this technique is what Panasonic did when they introduced the HVX200. They created such a website until it was uncovered that while it had no reference to being a Panasonic supported website, it was. They since took it down in shame."
Specifically, the space shuttle didn't have a launch escape system.
supposably the Shuttle was meant to be reasonably safe that an escape system is not needed, unfortunately it was not as safe as commercial airliners. Airliners from the 707 to the 380 don't have escape systems, they were designed to safe enough. Of course if the airplane is not that safe, re-design it so it will be. There have been crashes as nothing is absolutely safe. Like ejection seats were never considered for airliners, if you survive the punchout, will you survive the environment which you parachute into? i.e. frigid Atlantic ocean, barren hot desert, etc.
AC said, "from a documentary I saw on PBS, is that the escape mechanisms are largely an afterthought meant to soothe the public and legislatures." I don't think so. Escape systems were part of the design (in 1950s, ejection seats to tractor rockets to escape towers were all being considered. Though astronauts and cosmonauts are national heros, they in 1960s were military pilots on flights like test aircraft with ejection seats.
I was thinking what do they use now. Years ago I remember fire engines and trucks had strobe light on top of cab that flashes sequences which causes traffic light to turn red on opposing traffic. In late 70s or early 80s I saw a Dodge van that was parked in Quement Electronics on Bascom Ave in San Jose (you old guys remember that store, favorite among geeks back in the days when Fry's was a grocery store). I guess this person got ahold of one of these and voila, never gets a red light. Question I always wondered if that was legal.
Fast forward to nowadays, do emergency vehicles use such a system and is it RF based?
same with me, hacking traffic lights and reminded me of Benny Hill as the professor inserting hacked tape into the control system deck. Michael Caine said to the other members of his team though professor had "interesting reading material" to not make fun of him because he is very important for the job. I saw the movie last month (previously saw it in 1970s), featured the Mini Coopers that were screamers (back in the days almost all small cars were slow), Italian constantly honking horns (most in those little Fiats). In real life they do that even when traffic isn't moving.
I did a right turn at a major intersection but stopped before I turned. When I proceeded, there was several strobe flashes. Scared the crap out of me, muzzle flashes? Heard no gun shots. Lightning? uh clear skies. Am I gonna get socked with a big fine and huge increase of insurance because camera made a mistake? So far it's been months and nothing in the mail (unless there is an outstanding FTA waiting for 10-29), but I don't have that car anymore (bought another recently). Will such strobe lights freak someone out and cause them to t-bone me? I don't travel though that intersection much but when I do there is not much of a choice.
You think corruption is bad in Chicago, come to Atlanta or New Orleans sometime.
I wonder how such cities keep running i.e. water, power, sewage, traffic (though slow), electricity, food, etc. etc. and not collapse into some kind of Somalia environment with corruption gone rampant?
So the kids are learning, they get to use cutting-edge software backed by a hefty financial contribution, and the end result could be a new way to provide computer-aided teaching.
I was thinking first having kids learn about finances so they learn at early age the basics instead of becoming like many adults burden with debt from misuse of credit cards and borrowing plans. But that's another topic.
Getting back to this topic, I haven't seen the movie or read the book but I looked up Enders' Game to see what reference was. It seems creepy the parallels. Perhaps my Gripe of the Month is so much value is placed on warfare but I guess that's were progress is made. i.e. computers, internet, DARPA are all war department driven. While our economy tanks because most never got basic financial education, now there's war brewing in Ukraine and Middle East I guess emphasis is raising children to deal with it.
Perhaps by design they make the application difficult. It's tough, it's demanding, it's the hardest thing you will ever do. But if you have the perseverance, the skill to do it, then maybe you are worthy to join.
In my county, Santa Clara, it is $79k. They also receive generous benefits, and summers off. Teachers are paid fairly well compared to other non-technical college graduates.
I have to cry foul on this one. $79K is lot more than minimum wage but not high considering responsibility they have (future adults are children) especially this is Silicon Valley (one million dollars is not a lot of money). Yes, they get benefits as compared to other jobs that used to have benefits like pension plans but there is a jihad to eliminate those. Others not in the profession from billionaires to working stiffs don't believe teachers should have these.
You don't know teachers. Many have to use their earnings to buy supplies because politicos are too cheap to provide much of basic stuff they used to provide. Many teachers spend a lot of time after class and at home preparing lesson plans, etc. They don't have teachers aides like back in the days.
I don't want to hear this about there's not enough money, we find plenty to spend on countries, prisons, spying on citizens, etc.
Pardon me, the empire that keeps trade routes open prospers; the empire that turns to lording over its own people falters.
I think I've heard this before. If empire puts the squeeze on trade routes, then its own subjects are too scared to expand and explore. Someone mentioned this analogy in another forum of what's preventing space exploration (oh, I don't have time to get the details and properly word stuff). Getting back to this canal, China has money to burn so may as well put it into this canal to provide options (it is one they can control where Panama they cannot). There is also amount of ships that can pass through Panama, even if it were wider (which it will be shortly) I heard there is a "traffic jam" of ships waiting in ocean for their turn.
I can't think of any but what a reputation this country has: Hackers, Russian dash cam car crashes, a leader with Tsar ambitions. And yet they have best competition ballroom dancers (and many moved here to US).
My impression is Chinese are thinking big plans for future. Way back in late 1800s early 1900s US was thinking same thing: Panama Canal was a huge project with lots of opportunity for failure. But reaped benefits for decades after. Also Chinese have lots of cash and putting it into big projects (ok some will fail but whatever they will secure strategic advantage). Meanwhile US put lots of resources into backwards countries with not much to show for it.
I first used Justin but then later all I would get is a freeze frame with a cartoon of a dinosaur on top of image, "our monkeys are working as hard as they can to get it fixed" or something like that. So I then went to Ustream which seems to work fine except I never could get audio along with video, though I'm using the free version (maybe they don't send sound?). Livestream looks pretty good but for people to see it you have to get paid version. ParadigmDVD has nice Livestream streaming videos from dance competitions, nothing special on their end (I forget if they use PC or Mac) simply connect and use software from Livestream. They feed SDI from the cameras.
