People get confused between because the current satellite data providers (like HughesNet) are in geosynchronous orbit, which does suffer latency issues
Iridium is a LEO system that does not currently provided data services, and which has a relatively sparse constellation which requires a wide visible horizon to use
If all of your eggs are in one basket, i.e. fiber optics, then last mile, remote location, some jackass dragging an anchor or a recalcitrant local government can cut you off from access
Satellite communication is the more expensive option, but it can be worth it if there is no other means of connection
The real question is whether that market is enough to support their cost structure
It is actually calling for a few thousand satellites, but you are correct.... not that big of an issue considering the area that they are spread out over
I have to wonder, considering the Branson announcement, which billionaire is trying to distract from which billionaires actual commitment
Musk has the lead in the form of an actual, demonstrated, launch capability, but Branson made it to press a few days earlier
My guess is that he is the only one that they are willing to hang out as bait and get wasted so they can identify their target without any down-side of somebody else caring what happens to him
A lamb staked out to draw in the wolves
I'll probably wait to watch it on netfix in a few years, no rush to see it on the big screen
Deep space ship is called on to land on a planet Somebody sticks their face into an opening egg The person is brought back on the ship and they somehow miss that they have an alien embryo in it Ships computer and an android attempt to kill a crew member, by stuffing a rolled up magazine down their throat Alien pops out, grows without any food and kills most of the crew while they flail about the flamethrowers in a closed environment Hero runs around with fog machines and strobes flashing Hero escapes exploding ship (kaboom!) Hero fights off alien in their undies and drifts into space
Yep, that is Alien, a summer slasher flick stuck in space, but somehow everybody wants the same damn movie made over and over and will not accept when a new movie is made in the same franchise that attempts to draw the viewer further into a story
I am willing to accept that humans are fallible and likely to make horrible mistakes
The fact that Ripley did not make many mistakes is why she was a hero, everybody else working for Weyland Industries can be expected to act like a mindless sycophant because that is what corporations support
All of Dick's writing contains a great deal of self-doubt and delusion, it has to do with Dick's own mental state and I believe that stating that Deckard did not even understand what he was fits with Dick's other work
Iridium formed a corporation that included directors from all of the countries that they maintained major downlink gateways in These routed traffic off of the satellite network after a hop or two and then delivered the call over terrestrial networks
This corporate structure proved frail and was abandoned during bankruptcy restructuring The bankruptcy started in 1999 and received a judgement from the 2nd circuit court under appeal in 2007 that left ownership with Motorola and recovered a couple of hundred million dollars to the lenders (from the $1.55 billion that was invested)
The technology that Iridium used provided a very narrow upstream/downstream data capability to handsets, something like a 2400 baud modem. Motorola has developed an upgrade to start launching in 2015 that provides greater data transmission and more flexibility for locations of data downlink gateway locations The spacing of the Iridium satellites requires a very wide horizon to avoid dropped calls. The precludes use in inhabited areas where there are tall buildings as well as areas that have a varied geography with deep canyons and valleys
On the good to great side, Motorola developed a first of its kind production line for satellite manufacture, used a wide variety of launch partners (Russia, China, EU, Orbital Sciences and what is now called United Launch Alliance)
If Branson is going to be competitive he will need to beat the planned data link bandwidth of Iridium NEXT (1.8MB and 8MB data links), have a much denser constellation (to prevent the need for wide horizons in order to use the system) and strong control over the terrestrial gateways and networks
It would sure be cool, but the primary problem with Iridium was that there were not enough users who absolutely, positively had to maintain voice communications no matter where they were located. You may also wonder who Branson will contract to build and launch this system, since his competitors probably are the most capable of doing the work and probably have all of the launch windows locked up into the foreseeable future
And the gop leaders call dems baby-killing socialists that run death panels
I have a far greater chance of being poisoned by coal power plants spewing mercury and uranium into the air, finding myself kicked to the curb when too old to work, being mugged by some poor bum looking to eat or having one of my daughters earn less over their lifetime than any of the bs fears buttons that the gopers push on their base
I vote for issues that affect me, not imaginary fears, that is why I have not considered a republican candidate for national election since Reagan ran for office
Yes, the Republican strategy of disgusting and confusing their opposition with the state of US politics, while simultaneously drumming up their base with fear mongering worked
People who are not right-wing zealots need to hold their nose and vote against the goper scum, even if they only find that the opposition to those righties smells only slightly less bad
It's a game that must be played, even if you feel a little dirty at the end of the day
Are you going to make me work for less/no money, burn a cross in my yard if I act uppity, or shoot me if I get within 3 ft of you or behave 'aggressively'?
If you look at the original post, the AC was disparaging the article for focusing on coding over the 'rest' of computer science
My intent was to point out that coding involves a set of skills that have a wider general application than just focusing on computer science, which could be likened to training a person for a trade
I thought that I was being clear, and other posters seemed to get it, but you missed the point and essentially repeated what I said
start with learning logical foundations, then offer specific implementation skills if they desire it
at least you would end up with admins that have some foundations in development skills, rather than admins who memorized the manual for their favorite tech stack
There are elements of coding that require planning, logic and completeness that have impacts far beyond computer science. Teaching people to rack servers and install operating systems becomes for focused and resembles learning a trade. While there are plenty of positive outcomes of learning a wide range of computer science skills, I see the effects of learning how to code as having a wider positive effect
It looks like United Launch has been working on human rating the Atlas V and building a Crew Transportation System since 2006 http://en.wikipedia.org/wiki/A...
I can only imagine that this sudden rush of PR is due to SpaceX's recent smear of UL for locking them out of the military space market

The real question is whether that market is enough to support their cost structure
It really depends on how many sats SpaceX can jam into one launch and how much of their capacity is already committed to other contracts
Teledesic was dependent on other companies for launch, the one demo sat they put up was using Orbital's Pegasus
It is actually calling for a few thousand satellites, but you are correct.... not that big of an issue considering the area that they are spread out over

Gotcha, every story has to be wrapped up in a bow and dropped in your lap with no loose ends in a 90 minute running time.
I'm glad that Ridley Scott's other works like Blade Runner made it so easily digestible
