There were no changes that needed to be made because of the 2 digit date - it was solely an opportunity (mostly pushed by Lou Gerstner at IBM) to sell services. Who would have any desire to see government's role expanded to control CO2 emissions? I am trying real hard to figure this out. I know Dubya said in 2000 that he was the guy for less government, and if you want more government, vote for the other guy. I just can't figure out what sort of person would have ANY bias to promote a false problem so that government could control each private car, furnace, and fart..... This is just a guess, but could it be the socialists and communists? How would their agenda be advanced if government controlled everything? Would they abandon science to advance their agenda?

I suppose this thinking is a sign of modern times in wealthy countries. That is we are so isolated from nature (in our climate controlled homes) and protected from just about all our former natural predators, that we have to start making up things we need protection from. Probably its an instinct we can't get rid of, Human nature is destructive. It can create socialism. Perhaps it is our instinct to control others that made the founding fathers try to protect us from the sort of control freaks that would use Global warming as an excuse to enslave us. In 1972 I saw the full court press of college try to brainwash me into thinking that the world was going to end unless we intervene with government. Who has a nicer environment, the old USSR or the USA? Where do you want to live? It seems that all men would be tyrants, just like 200 years ago. Liberals make Hell on earth. The are zombies that eat the brains of those who would go to college, watch TV, go to the movies, or listen to NPR. Listen to the wimpy right spew the truth and get beat by the fast sound bites of the leftist propaganda. Today NPR dug up a climatologist who believes in global warming. Those are hard to find! And no challenge to the his one sided propaganda. -- Be careful what you pray for, it can happen. |

Question for you Terry...there was about $600 Billion dollars spend on Y2K remediation in the 4 or so years prior the event. Can you honestly tell me, that without that remediation, things would have been just warm and fuzzy? Well, it employed a lot of computer programmers. I think the entire thing was cooked up by those folks. They decided they were working themselves out of a job about 40 years ago. So they built in a few 'traps' to be sure they'd be needed down the line. We just found the first one. Wonder when the Y2.414K problem's gonna crop up....

I figure that I have maybe 25 years left on this rock. 25 years in the span of geologic history is a nanosecond. Nothing is going to really take place in my lifretime. If you are so afraid of global warming, I suggest you go get an air conditioned closet, lay in some supplies, go in there and lock the door, and never come out. For those of us who like to live every day and enjoy life, it will go on as usual. I just saw on TV where an asteroid will pass within 24,000 miles of the earth in 2029. If there is anything that one should be concerned about, it is something like that. An asteroid collision could end life as we know it in about six weeks. They say that the asteroid should be visible from Great Britain. I hope I am around then, but doubt it. In the meantime, I shall continue my hedonistic ways of beer, football, fishing, motorhoming, metalworking, traveling, enjoying my grandchildren, eating, making love, and all the other stuff. I hope you are comfy in your closet. You could always move to Kalifornicate and run around waving your arms in the air like all the other loonies. Steve |

What's junky about the global warming science? A front page article in the Wall Street Journal on 2/14 In Climate Debate, The 'Hockey Stick' Leads to a Face-Off went into great detail about how the data has been mis-represented. The original scientist has made some corrections, but now won't even share the data he originally used. (I am not a subscriber to the online edition, so can't post the article here.) Global warming is a litmus test for junk science. Humans simply do not make enough CO2 to affect climates. Edward Teller has pointed out that one good nuclear blast, imitating Krakatoa, could put enough dust in the air to cool off the globe for years. Every penny spent to mitigate this non-existent problem is wasted, and should have been spent on issues where the problems are real. |

I wouldn't call it a "good" dissertation. "Consensus" He does a really good job of laying out how the term has been abused and molested by politicians, but all that established is that we now have two versions of "consensus." One version is a bunch of scientists going "Yah, that sounds good, but I haven't checked it out," while the other version is a bunch of scientists going "Yeah, I reviewed it and it's correct." Rather than point out that both versions are floating around in discussions and when you hear "consensus" you need to figure out which one you're hearing about he simply implies that anything billed as "consensus" is crap. In fact, he states: " There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period." Well, it isn't period, because there is occasional overlap that you'll need to allow for. It's also kind of funny he uses E=MC^2 as an example of non-consensus science because some parts are still unproven and just kind of accepted for now. Look up the "Gravity Probe B" experiment for more details about that. He also goes and makes a somewhat large leap of logic early on when discussing Drake's Equation. He (rightfully) points out that an equation of nothing but unknowns is worthless. However, then he links it to nuclear winter predictions by pointing out an equation the debaters implicitly used while arguing. But the difference is that it's not an equation of all unknowns; you can experimentally determine how much ash would be generated and how it would be distributed within some error margin. You might wind up with an error margin so large you get useless results, but you'd have a starting place to refine your experiments to reduce that error to a useful level. So, not necessarily useless as Drake's Equation. Could be, but he can't connect enough dots to show it. However, that doesn't seem to dissuade him from carrying on as if his case is bullet proof. And while all the repeated examples of people who've given bull**** predictions in the past is amusing, it's also meaningless. Hiding behind science or not, bull**** predictions are all over the place and for every argument out there you can probably find a bull****ter or two. That doesn't necessarily mean everything (or even anything) else is bull**** as well, though he does imply it. Again, a big logical leap. His take on models is a half-assed take, kind of like he did with "consensus" above. Yeah, models that just model the future are useless, but models that are legitimate get compared with collected data to verify their accuracy are and then used to extrapolate a plausible "what if" scenario. A big user is NASA who has been using orbital models to fling satellites around the solar system for some time now quite successfully. Not all models are the creation of programmers trying to justify their own jobs with a flurry of numbers as he implies. Anyway, he goes on and on, building his own model (which he thinks is junk, I suppose) of what amounts to a set of symptoms of junk science, then he points out that global warming suffers all of these symptoms. He mentions that global warming fits his template of nuclear winter, SETI, and whatnot, but nowhere in that entire dissertation does he draw up any specific examples of global warming theories that actually are junk science. All of it is just a big maybe. So, I really don't see at all how this shows what's junky about the global warming research that's going on. That said, I do agree with some of his conclusions, even if I think the way he got to 'em is iffy. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

I'm a believer, but it's not going to be happening on anything like a short time scale. You and your family and their children and THEIR children, to many generations, will be long dead before there are any serious effects, You know this how? Also, sometimes, media hysteria and other people's hysteria can be the only thing that makes the mass of people aware that anything is wrong, and thus _maybe_ slow the problem a little. |

vaguely proposed a theory .......and in reply I say!: remove ns from my header address to reply via email You have been listneing too much to Suzuki!!! Do a google search on the guy and read some of the counter information. At 57 I have heard them all. WW2 caused massive climate change. The atomic tests were doing it. The satellites were doing it. No worries we are going to have mass starvation from overpopulation by 1980. In between California was going to sink into the ocean. But is there not just a slim chance that "listening to too much Suzuki" could be some of the reason we did _not_ starve by 1980? For instance, the latest US cars are getting amazing fuel consumption. This seems to be laregely caused by pressure to get fuel-efficient cars. This is not all economic. I reckon people would have happil,y gone on grumbling and using great v8 gas guzzlers if nobody stood up and shouted about problems. Get on with your life. That's a lot of the problem. |

"Back when I was a boy" (or as my daughter says 'back when dinosaurs roamed the earth...') every bit of memory cost. Figure all those data files had a date in there, if you could save 32 bits somehow in each one, that adds up after a while. You'd only save that much memory if you were foolish enough to use BCD or some other inefficient storage scheme. You can store a whole lot of years in 16 bits, even without going to the trouble of normalizing to a common date (as Unix did). The problem was, they probably used 16 bits of space to store the 2 digit year values anyway: "Gee, let's store numeric data as an ASCII text field, that'll simplify life *so* much." Hence the XX year format rather than XXXX. But honestly I figure they just wanted to see that they'd have jobs right around the year 1999. I disagree, it was probably a hardware constraint (16 bits max on a hard drive) plus a shortsighted perspective on how long the machines would be around. Honeywell decommissioned the last of its GECOS mainframes (many dating from the '60s) just before Y2K by replacing them with Oracle applications and databases running on Unix boxes. A smart move, in my opinion, and I had nothing to do with the decision or the implementation. Right now I'd feel safe in limiting my databases to Y64K (16 bits) and it wouldn't be about assuring some contract work when the limit is reached. Pete |

A smart move, in my opinion, and I had nothing to do with the decision or the implementation. From 1973 to 1977 I worked with the McGraw-Hill circulation database for 26 magazines on a daily basis (something over 2 million records, a mainframe system with an elaborate subsystem of satellite tapes and temporary working files). Each record had 23 fields; all but the address and name fields were cryptic codes. Subscription years were stored as two-digit codes, the last two digits of the year. Software managers who were commenting on the Y2K problem before the turn of the century said, for the most part, they had to squeeze the fields down to the smallest possible size to keep record sizes down and that they never anticipated that the software would still be used a quarter-century later. I don't know what the whole story is but it sounds very reasonable, having worked with those guys every day back in the '70s. -- Ed Huntress |

My understanding from talking to the folks who did a lot of this is that you are correct. They were just trying to save two digits in the data, multiplied by a lot of data files. Remember, when you bought a PC then, it had no hard drive. Those were aftermarket. 20 megs of hard drive space was huge.

I specifically remember being taught to use 9999 as a flag in the date field as "done with job". The last entry in a table would be 9999 which was the exit condition for whatever routine was operating on it. I guarantee that if anyone was still using several programs I wrote when Y2K came around, they had problems on September 9th of 1999. Remember, when you bought a PC then, it had no hard drive. Those were aftermarket. 20 megs of hard drive space was huge. Heh...I didn't get a hard drive until about 6 years into it. No floppies for the first 3 or so, it was all on magnetic tape. At 150 baud. |

Global warming is a litmus test for junk science. Humans simply do not make enough CO2 to affect climates. If there could be a coming together of liberals and conservatives, conservatives would have to admit that there is science to evolution and liberals would have to admit there is no science to global warming. We could respect for other peoples faith, be it liberal or conservative, we just don't want our nose rubbed in it in schools and in the news. -- Be careful what you pray for, it can happen. |
