Hydrogen can be used as a drop in replacement for anything running internal combustion or just combustion for heat (smelting or kilning). The hydrogen can be produced via electrolysis of water and any form of clean power can run that process.
However, where CO2 emission is part of the actual industrial process such as converting iron to steel (adding carbon via coke is the entire point) or kilning cement (CO2 is part of the chemical reaction for some types of cement), there really isn't a good means of reducing CO2. Certainly you can reduce the CO2 from the power supply end with alternative energy sources, but not as a direct by-product of manufacture.
ses beams of light to deliver high-speed, high-capacity connectivity over long distances
I read the article. It was short on technical specifics. So I looked it up on wikipedia. Free Space Optical Communications (FSOC). So what makes them choose this as a better choice than older proven line-of-sight technologies like Microwave radio relay. Microwave formed the backbone of AT&T and MCI long-lines and had enough umph to carry live video. Does the light relay system really have that much more bandwidth than microwave? FSOC looks inferior to me. Shorter distance (a few hundred meters vs hundreds of kilometers for mw and more attenuation with weather (fog, rain).
Granted, "The Center for Consumer Freedom" is a blatant lobby group for the food industry, but their radio ad campaigns that they run in the DC area are hilarious.
For real laughs, listen to their archives of radio ads.
So why not both get rid of it (as a separate executable) and keep it at the same time by implementing aliases against the equivalent powershell syntax. I don't see why they shouldn't just have powershell recognize a cmd-script or statement for what it is and run the appropriate cmdlet with sensible pre-set defaults that emulate the cmd behavior. Powershell already has aliases, so this wouldn't be very hard to fully implement. It is sort of similar to the way that GNU BASH can be run in posix mode when invoked as 'sh' and recognize a slightly different syntax from the usual gnu-extended version. IIRC, most gnu utilities can be invoked in posix mode and take different argument syntax than what it normally expects in gnu-mode.

Back in March , in a related story, one of Cisco's VPs for security, John Stewart, was quoted in the press as saying that Cisco would ship to decoy addresses to circumvent interception by the Government. Supposedly, this was at a roundtable discussion during the Cisco-Live conference in Melbourne, but there is no video of the discussion on the Cisco-live website.
I've heard he was misquoted and they don't actually do it. Does anybody have link to actual video of this discussion? Are they still doing this? Has anybody used that service?
So lots of people her complain about "Big Pharma" and then go on to claim the socialized medicine in Europe & Canada is a superior model with cheaper drugs. How are they doing developing new antibiotics (or drugs generally)? And how do they how do they finance and amortize the cost of development if selling price is so cheap?
Well if they are talking about the toy in the picture and 40 meters is the height, a fire hose or pitched base ball can bring it down too. If it is low enough to be brought down by a fire hose then it is too low and a nuisance.
What would be more interesting is if sound can bring down a more advanced aircraft that relies on computerized gyroscope stabilization like a F-35 from a few kilometers.
If you were here a bit over a decade ago, you remember these little babies the HERF guns, http://tech.slashdot.org/story... & http://science.slashdot.org/st.... They would probably work on drones (and more). Given the Inverse-square law, I don't remember what the range might be though.
In that case, can't they just globally fix it server side, by 1) filtering it out of the stored history, and 2) filtering input to prevent it in-bound?
I'd love to see a city/neighborhood install pnumantic tubes for instant delivery. Its a 19th century technology that is proven and feasable but is strangely seldom used. Just laydown 1/3m (12 in) plastic piping, have machine addressable containers, and install electric-mechanical sorters/routers at each node that can read the addresses and kick the container into the correct junction. One the receving end, the receiver would put the empty container back into the system and it would be routed back to the origin or next node calling for an empty. You could have a payment system for container rental/transport.
There would be an inital install cost, but that would be recouped by the cheap operation.
Order milk and a loaf of bread from the grocery and have it delivered to your door in 10 minutes. Mail could be put into the system at the post office and be delivered to the door without a carrier.
Are you jesting? A judge can ban you from everyplace excepting a 5x8 concrete pad enclosed with iron bars (commonly referred to as a "cell").
In reallity, the Gov't rarely punishes non-violent acts of civil disobediance/protest with anything more than a fine and time served while awaiting trial (days to a few months). For history, look at all the anti-nuke demonstrators who regularly chain themselves to the fences at air force bases. The key here is non-violance. As long as nobody got hurt and there wasn't any real possibility of anybody getting hurt, they will give the guy a small to moderate fine.
If he is not close to retirement, he might get fired from the postal service.
The article gives a post-apocalyptic senario. Most of the high-techy alternatives like solar and nuclear require an establish industrial infrastructure to produce. You will not bootstrap to building a solar panel outside your mud-hut by rubbing two sticks together to melt sand into silicon. You will build a solar panel by producing refined copper and silicon in factories running on coal-generated electricity until you have enough capacity to replace the coal. So no, there is no realistic senario in which you just skip burning fossil fues and go straight to high-tech (unless you want to run the plant by chopping down and burning all the forests, which is probably a worse solution than fossil fuels). Even something like hydro-power requires industrial infrastructure to build large scale. Otherwise how will you get the steel and cement to build the dam? Or the steel and copper for the turbines and windings?
Serously, I find it amazing that these companies would pay to move a worker from Calcutta but not from Omaha. "Oh we looked in Silicon Valley's and Seattle's rarified labor markets and couldn't find anyone... so now we must look overseas!" Why don't they hire from Nebraska or Kentucky? Why?....because it never even enters their minds.
Next, H1-Bs don't create jobs because they are not allowed to start a company. The system is designed that way. (OK, legally they can create a corporation on paper, but the condition of their visia is that they are only allowed to be employed by their sponsor and aren't allowed to be employed by or draw salary from their own company, so the practial effect is they can't work for their own start-up). If they are creating companies and they or their famlies are working for the start-up, it's a violation of their visa.
Here's how to quash this BS. Create a national registry of unemployeed STEM workers and make them offer to pay the moving costs to move the employee from whereever to the job site. NATIONAL, not just Seattle and San Jose. Make them hire off that list before they can go overseas. If they can show they offered a job and offered a move to somebody in the US and got turned down six times, then they can do the H1-B thing.
Next, if they do hire a H1-B because there is no "qualified" american worker, make them sponsor a scholarship in that field and train somebody until they are qualified. If they hire an engineer on a H1-B, then they must pay the scholorship and internship for an american to make him qualified. That newly minted engineer now goes into the job pool.
Soon it will be a sin for parents to have a child which carries the heavy burden of genetic disease.
But not yet please. I have two issues:
First, We still don't know enough to prevent unintended consquences or complications. We could edit-out one problem and accidently edit-in another.But one day, in the not-so-distant future, perhaps another generation or two, yes - definately. We should erradicate all heritable diseases.
The second thing, I would draw the line between correcting errors/curing diseases and between creating eugenic supermen. Please no Gattica-style selection of socially prefered traits to create a dis/u/topia of ubermenchen and untermenchen.

I thought the point of a major version (not necessarily in the Linux kernel, but software generally), was to signal a major change that either:
includes ground-breaking new features
includes serious archtectural reworking
breaks backwards compatibility
If the changes are merely incremental bug-fixes and minor feature additions, stay with minor versioning. Otherwise, you are not versioning; you are branding (viz: Windows 8... which IIRC is version 6.2)

The Red Cross is the international organization responsible for monitoring conduct of belligerents, documenting,and reporting war crimes and atrocities. The ICRC ought to be publizing this far and wide as an example of the shameful savagery it is.

State parties (signatories) to the four Geneva Conventions of 1949 and their Additional Protocols of 1977 (Protocol I, Protocol II) and 2005 have given the ICRC a mandate to protect victims of international and internal armed conflicts. Such victims include war wounded, prisoners, refugees, civilians, and other non-combatants."
Perhaps I'm missing something here, but I really want my Ansible. So the classic channel is required to report observed measurements at the origin to compare against, but they say they can deterministically set the state? Sooo..... why not do this to eliminate the need for the sub-luminal classic channel, if they can deterministically set the state at the origin. Operate on a clock cycle and deterministically set the state to an expected ground state at a certain point in the cycle. When a read operation measures something other than the expected value, that counts as an information transmission. In otherwords anything not 0/blue is read as a 1/red. Say 4 ticks per cycle. First tick, zero state/0/blue. Second Tick, origin flips a bit (or not). Third Tick, destination reads the bit knowing anything not 0/blue is a bit flip. Fourth Tick both sites reset to zero. The key is that on the third tick, the destination will always expect to read 0/blue, so anything else is a transmission.

It would be interesting to know if a sorta equilibrium occurs where the warmer winters means less fuel was burned.
There are also some IP network connected medical devices with virtually zero security. Check this out. This was definitely a WTF moment.
