1. The myopia is that they assume everything will be done EXACTLY as it has been done for the last 30 years, which causes the long trip times, the small living spaces, the lack of gravity. When you decide to not use the best technology to do the job, all sorts of bad secondary effects will happen.

My point is mostly that in these reports of "human problems in space" the reports specifically pick out the worst combination of chemical rockets, zero-g conditions and small habitat sizes, all of which are known to be problems, and all of which a long term mission would be avoiding because better solutions already exist that would fix these issues and confer many other benefits. So in essence, I would say this report would be better titled "Using the wrong tech for space missions is bad for the human body"

2. NASA started and then abandoned much of the tech. NERVA's has many successful tests on the ground and where ready for in space testing before the program was cancelled, so while there is still more work required, in no way is this a pie in the sky project, its just mechanical engineering. Expandable habitats are now being developed by Bigelow space craft and there are 2 successful platforms in orbit now, so it development seems well on its way for that project. Tethers or rotating spacecraft is the least developed of technology I have talked about, but the simple tether and counter-weight system is just that, simple so development of could easily be done in LEO

NERVA engines reduce trip times, less time during the trip means less radiation exposure. Nerva engines are already 2x more efficient than chemical rockets, so since mars is.... doable chemically it becomes much easier with a NERVA or other NTR design. Faster trip times reduce infrastructure and consumable needs, it really cascades from there.

Zero G - 2 ways to do it... Big rings give slow rotation which negates vertigo OR you could take a spacecraft and have a long tether to a counter weight and spin the whole ensemble on its center of gravity.

Isolation - Give people more room and more stimulus and reduce the trip times.

Every time I see reports like this, I am stunned by the myopia of the researchers. Everything that they list can be easily countered using proven technology.

Radiation - Use a NERVA engine to reduce trip times, the extra power you have from the reactor could be used to have more shielding on the vessel and/or magnetic shielding to protect from charged particles.

Zero G - Spin rotation of the habitat, or spin the craft itself with a counter-weight.

Isolation - Expandable habitats give more room per launch than anything else, so you can have room per person and more people to interact with. Think cruise ship versus submarine.

With the current revolution in the heavy lift industry, all of these technologies render the above problems moot.


In UK, Google Glass To Be Banned While Driving 214 214

RockDoctor writes "Stuff magazine, a gadget oriented mag, is reporting that the UK's Department for Transport is planning to ban drivers from using Google Glass, using the same law (1988 Road Traffic Act) that is used to ban drivers from using hand-held mobile phones. While there are obvious parallels between the distraction potential of the mobile phone and of Glass, there are arguments in the other direction that the speech-control aspects of Glass could make it less distracting than, say, a touch-screen SatNav. So, to ban Glass while driving or not? Typical fines for using a mobile phone while driving are £60 cash plus three penalty points on the driving license; the points expire three years after the offence and if you accumulate 12 points then you've lost your license. Repeat offenders may experience higher fines and/ or more points. Around a million people have received the penalty since the mobile phone ban was introduced in 2003."

I deal with ALU everyday and I say that their networking designs are finest 1990's era engineering I have ever seen. Multi-state spanning tree domains, Deathly fear of routing protocols, insanely expensive routers with crappy performance and odd limitations that are designed solely to sell insanely expensive cards. And that's just their tech, the level of bureaucracy and hate for co-existing with other vendors is astounding.


Motorola HC1: Head-Worn Computing For Workplaces With Deep Pockets 42 42

alphadogg writes "Motorola Solutions has unveiled a head-mounted, voice-controlled computer that's targeted at the military and other industries where workers need hands-free access to information. Called the HC1, the device runs on an ARM processor and has an optional camera to send back real-time video over a wireless network. Unlike Google Goggles, though, the HC1 is aimed at the enterprise market with a price tag of $4,000-$5,000 per unit. Areas the company has been experimenting with include 'high-end repair markets,' such as aircraft engines, said Paul Steinberg, CTO of Motorola Solutions (which is the part of Motorola Google did not acquire). 'Emergency medical personnel at trauma centers might be looking at this too.' The HC1 will augment what users see by providing additional data, he said. Multiple units could be networked together and share information. Video here. "

The problem is that since WWII the groups we tend to fight ignore all treaties. So if we agree not to use "cyberweapons" and thus do not buld effective counter measures, we leave our stuff open to attack by groups who would not give a second thought to vilating a treaty, be it for cyber, biological, nuclear or chemical weapons.

Not that they really need to hock wares. Thier stuff rocks, it was easily one of the best purchase decisions I ever made and I have never had a regret for it. Not to mention the group I deal with there is very very good at what they do.

Sadly, I sound like a shill, but my expierance with them has been that good.


Video Blue Gecko is an 11 Year Old Remote Database Administration Startup (Video) 63 Screenshot-sm 63

A company that has been going since 2001 is not exactly a startup, but Blue Gecko co-founder Sarah Novotny says that maintaining a startup mindset has helped her company keep going this long, with no end in sight. If you are thinking about starting an IT business (either now or in the future), especially one you hope will have remote clients and possibly a far-flung workforce, you should listen carefully to what Sarah has to say.

All syllogisms have three parts, therefore this is not a syllogism.
