Bradley Manning Convicted of Espionage, Acquitted of 'Aiding the Enemy'

gordona Re:I guess Snowden saved Manning's life then. (529 comments)

what damage? All he did was release the information that NSA was electronically evesdropping on US citizens. Something everyone knew anyway including our "enemies". He released no names of any covert agents, troop movements, or what Obama had for breakfast.

TV Programmers Seek the Elusive Dog Market

gordona my dog stares at the TV (199 comments)

My pooch will stare at our 42" LED screen. He goes crazy when a talking head appears and stares back at him. The dog doesn't like strangers staring at him. He also reacts to other animals on the screen and cartoon characters. Sometimes he'll run around to the other side of the wall on which the TV is mounted as if he is looking for something behind the TV/wall as if the TV were a window to the other side of the wall. And no, the dog is not on drugs (neither am I).

PDP-11 Still Working In Nuclear Plants - For 37 More Years

gordona predecessor to PDP11 (336 comments)

The predecessor goes back to the MIT machine in the 60's, the Link-8 which became the PDP-8. It had two DEC tapes, 4KB ram. We programmed it in LAP-4 and had to key in a bootstrap loader on the front panel to load in the OS. At the time we wrote a 64 point FFT and a routine to output the results to a Calcomp plotter. It took 5 minutes to run the FFT. Memory was divided into 2 2KB segments, one for data and one for program. We used one page (512KB) as an executive routine and the other 3 pages to program the FFT which kept the DEC tapes spinning as different segments of the program were shuttled in and out of those 3 pages.

USA Calling For the Extradition of Snowden

gordona Thats BS (955 comments)

If you listen to the interview between Greenwald and Snowden (on http://democracynow.org/ you will see that Snowden could have released a lot of information that could have made him a lot of money and pretty much taken down the whole program by exposing specific details about programs and individuals. He did none of that. It should be up to the American people to decide if we want such surveillance. If we do then keep these programs. If not then the answer is obvious.

US Postal Service Discontinuing Saturday Mail Delivery

gordona USPS budget problem created by congress (582 comments)

"The congressional notion was that the Postal Service was making lots of money selling its products and services, and so it might be a good idea to put those profits into pre-funding future retiree health care benefits for the next 75 years and do so in a decade. No one else, public or private, does this – but it would put the Postal Service that much more ahead of the game in terms of future liabilities. And so, in 2006, Congress mandated that the USPS do so, at a price tag of about $5.5 billion a year. " (http://www.cnbc.com/id/45049636/Fixing_the_US_Postal_Service039s_Finances).

Fukushima's Fallout of Fear

gordona very low doses????? (124 comments)

I don't think there is a low dose minimum. Sure we have background radiation. So this plus whatever folks received from the leakage from the Fukushima plants is considered low? What BS. Just because the effects might not be seen for 10 or 20 years doesn't mean there aren't any. Of course you can't prove a negative and trying to prove an effect that happens decades later is nearly impossible. Oh wait, we can do an experiment. Lets take a bunch of identical twins, expose one to so-called low level of radiation and the other to no radiation, keep them in an insulated box for several decades and see if the one exposed to the radiation gets sick. Oh you say we can't do that experiment? Of course. But looking at the basic physics and the effects of radioactive molecules on nearby cells, we can with a certain amount of certainty say that radiation in any amount will have not so good effects on the human body. Look up some of Helen Caldicott's work.

26 Nuclear Power Plants In Hurricane Sandy's Path

gordona Re:Around here (392 comments)

What I heard this morning is that a number of the plants are in a refueling cycle and not in operation. No fuel in the reactor and at least some of the backup diesel generators undergoing overhaul. The current NRC regulations do not require that the spent fuel ponds use the generators for cooling the spent fuel rods, instead relying on the grid. So, it the grid goes down, which it likely will, then its possible that the spent fuel rods can overheat due to lack of circulating cooling water. That's probably the major issue here.

There was a situation last year from Irene. There was so much water that the propane tanks floated away down a river toward a hydroelectric dam near one of the reactors (I think it was in Connecticut). The road to the reactor was closed fearing an explosions from the tanks. I don't think that disaster planning for the reactor design included such a scenario.

This was my post, I forgot to log in.

Study Says Fracking is Safe In Theory But Often Not In Practice

As I understand it, each hydraulic fracturing well requires several million gallons of water. In areas out west at least, water is a scarce commodity.

Fracking Disclosure Rules Approved In CO

gordona Re:Great! (279 comments)

Yes Colorado is a water poor state--semi desert. Fracking uses a shit-load of water that cannot be reused. There is an ever increasing demand on the Front Range (Pueblo to Ft Collins, including the Denver metro area) for water (can you say uncontrolled growth?). The proposed source for this water is from the western slope, ie, the Colorado River drainage, which is already over subscribed! I guess at some point this will be self limiting. Not too long ago, Douglas County, north of Colorado Springs was the fastest growing county in the country. The wells that people had on their properties were certified by State Engineers as being 100 year wells. The rapid growth and development depleted those wells in just a few years, leaving the home owners literally high and dry. So, lets keep fracking and burning the natural gas with its, albeit reduced, CO2 levels, and deplete the water supply and raise the environmental temperature. That will surely limit growth and the need for water and natural gas from fracking.

Hydrogen Fuel made with Sunlight and Zinc

gordona gordona writes  |  about 2 years ago

gordona writes "Perhaps free energy or nearly free is on the way. A PhD student at the University of Delaware had demonstrated how that free hydrogen gas can be generated with sunlight, zinc oxide, and water. A chamber that holds the zinc oxide is heated by concentrating sunlight to 3500 degrees Fahrenheit which vaporizes the zinc. The zinc vapor can then be put into water which then reacts to form zinc oxide releasing hydrogen. It isn't stated how the zinc vapor is separated from the oxygen that is generated however and its not clear if the process is scalable."

Possible safety shortcuts at nuclear fuel facility

gordona gordona writes  |  more than 6 years ago

gordona (121157) writes " The IEEE Spectrum has the following item:

The Chemical Engineer, a magazine published by Britain's Institution of Chemical Engineers, is reporting allegations that safety standards are being neglected in the design of a nuclear fuel fabrication facility being built in South Carolina. The $4 billion plant, near Aiken, will produce so-called mixed-oxide fuel, consisting of uranium and plutonium recovered from spent nuclear fuel or nuclear weapons. Dan Tedder, an emeritus professor of chemical engineering at the Georgia Institute of Technology, told The Chemical Engineer that basic process design information was incomplete, with serious implications for safety. Tedder, who served last year as an independent technical reviewer on the project for the Nuclear Regulatory Commission, predicted that safety problems will manifest themselves when the plant is operational. "The documentation provided in the license application is very superficial" and "isn't consistent with reasonable and generally accepted good engineering practice," Tedder told The Chemical Engineer. The NRC has dismissed Tedder's accusations as unfounded but has barred access to documents in dispute, on security grounds.

John McCain's Tech Policy

gordona gordona writes  |  more than 6 years ago

gordona writes "The current issue of "Mother Jones Magazine" (http://www.motherjones.com/washington_dispatch/2008/07/john-mccain-no-technology-policy.html), compares the technology policies of the two major presidential candidates. Other than sweeping generalization, McCain offers little in the way of specifics and taking a hard-line on using technology by pedophiles. Oh wait, he promises a better battery. How you may ask? By offering a $300M prize. He is against net neutrality because it is an attempt to micromanage business and innovation. And apparently, he cannot use a computer without assistance. It is not known, however, if he thinks the internet is a series of tubes. Obama on the other hand appears to be more astute with regard to the technology — he apparently has an iPOD! Of course, all the candidates' positions are subject to change once elected."

Trade of enriched uranium increased oil production

gordona gordona writes  |  more than 6 years ago

gordona writes "According to Yahoo News (http://news.yahoo.com/s/afp/20080516/pl_afp/mideastusdiplomacybushsaudideals), the US is making plans to offer the Saudi's enriched uranium in exchange for "protection" of the oil in that region. Presumably, this offer is also for increased production. I don't think the Saudi's have nuclear (nucular) reactors yet, however. In addition, last Fall, the BBC reported that the Saudi's were offering Uranium to Iran (http://news.bbc.co.uk/2/hi/middle_east/7073699.stm). I guess the bottom line here is that desparation rules the day. In Iran, before the Shah was deposed the US was planning on developing nuclear power there. That project was never completed (started?) when the Shah was deposed. If it had been, then the current regime would have had nuclear power. Can the same be said for Saudi Arabia? How stable is it there and what are the unforseen consequences of our benevolence?"
