We don't have to ignore depleted nuke-fuel. For one thing, there are regen/breeder reactors. For another, fuel usage per year is much less than the environmental damage from fossils. Lastly, we only need the nukes until fusion plants are developed. They're working on NIF just down the street, at LLNL. The point is that, the enviros won't let us build fossils and the anti-nukes wont let us build nukes. NIMBYs wont let us build either one. Until that's settled, we wont get any new plants of either stripe. a.k.a. a self-destructive deadlock. I reiterate that it will be more than 5 years before we can get the first batch of new power plants online. The next sucking sound you hear will be businesses evacuating California, once they figure this out. "No tickee, no laundry" and no power, no business. By the time you figure out you need new plants, it's 4 years past starting to build one. Ironically, American companies are building and selling pocket nuke plants that are safe as houses ... for sale to North Korea and Russia. The $4.5B we just paid to the generator companies would have bought 5 or 6 of those. Maybe, the rest of the world deserves better than we do ... But, I digress ... you have been an excellent example of what I wrote about, thank you kindly. Anyway, I wont reply on this thread, on NANOG, anymore. It's getting too far O/T. It has been suggested that we find another list for those that want to discuss this further. I may post on that tomorrow. > From: Roger Marquis [mailto:marquis@roble.com] > Sent: Saturday, April 28, 2001 10:25 PM > > All true, but irrelevant to the people with cancer in the Ukraine > and elsewhere.

Young Network Operators (was RE: California power ... unplugged)

Smith" wrote: > Perhaps you just need some properly built nuclear plants. :) Ontario has New nuclear plant design has some interesting differences from the old plants. What caused these changes? Of course, there were several incidents which woke people up. But another change also occurred. Nuclear engineering fell out of favor among college students. There were fewer youngsters entering the industry after TMI, so the average age of nuclear engineers has increase. With age comes wisdom, or just senility? Older designs were "big" in every sense of the word. If you can only build one plant, you better make it the biggest plant you can. Old designs reflected a deep belief that you could maintain control. Control systems kept the system safe. The engineers were smart people, and had confidence in their ability to engineer their way out of trouble. Is this an error of youth? A young driver believes he can control the car in any situation, an older driver keeps the car out of situations requiring control beyond his ability. What does this have to do with network operators? With the downturn in the high-tech job market, and the apparent end of the 21-year old CEO getting $100 million in venture capital, will we see a similar increase in the average age of network engineers? And with the increase in age, will we see more conservative network operations coming out of companies? Or will we adopt the extreme slow conservatism of the telephone industry? Sometimes you need to accept some risk in order to innovate. If you never deploy something until it is perfect, it will take a very long time.

California power ... unplugged.
by Roeland Meyer 29 Apr '01

This is a follow-up of something I posted last November. The Enviro-Nazis are at it again, demonstrating why no new power plants have been built here, in the past 15 years. Hunter's Point: San Francisco proposed doubling capacity of the Hunter's Point facility by building a duplicate plant right next to the existing one. Local groups are protesting on environmental grounds. Coyote Valley: San Jose finally approved the construction of the CalPine power plant, needed to support the Santa Teresa, Coyote Valley, and Morgan Hill areas. But, local slow-growth advocates and enviro-nazis are protesting and threatening to sue San Jose. San Jose is asking the state to help smooth things over so that the plant can get built. Between the enviro-nazis and the no-nukes folks (they *are* different groups), California has been dead-locked on power plant construction for almost 20 years. The winning strategy; get locals to buy into the "not in my backyard" sentiment (an easy sell, it worked in stopping prison construction, as well). This, in a population so brainwashed, it actually wants to pay more taxes, even when they are already taxed at the 60% level. Further, this same population thinks that electric cars are the answer to the environmental problem, since they produce no pollution (a fallacy and contradiction of known facts, for those that don't know). In 20 years, CA has gone from a 300% over-capacity to the present shortage. In the past 8 months, energy costs have sky-rocketed 700-900% on only 3% increased usage. The reason; CA doesn't produce enough of its own power and, in the last year, has crossed over to being dependent on energy imports, rather than a supplier of energy. This is a crucial transition that CA was warned about over 25 years ago, when the no-nukes folks were very active here. Obviously, they didn't listen. Estimates are that, it takes two years to bring a fossil-fuel plant online and 3-4 years for a nuclear plant. However, fossil-fuel plants like all plants, have to meet the California Clean Air Act. This means that they may not be allowed to operate, due to environmental constraints, even if they were magically built tomorrow. Remember that California has its own, much stricter, environmental guidelines. These are guidelines that only nuclear plants can approach. Yet, this is in a state that is littered with "nuclear-free" zones. Bottom-line: 1) Expect the paralysis to continue for quite a while and then wait 3-4 years for plants to come online. Reasonable estimates are out past 5 years. 2) Expect increasing levels of power outages, both Summer and Winter (Stage 3, rolling blackouts). 3) Expect increasing energy bills, both in gasoline and electricity, on the order of 300-500%, in the next 5 years. 4) Expect a coming exodus of industry, to anywhere but California. 5) Expect ever more totalitarian regulations, to manage the long-term emergency (you'll have to get a license to plug a toaster into the power-grid). These regulations will not go away, even if we get enough power plants online. 6) Dick Cheney was correct, we need to start building nuclear plants out here. 7) Data centers and colo providers will come under increasing pressure to pay their "fair share" of power generation (this means that they get charged double or even triple). 8) Backup power generators will have to be replaced with units that can stand increased duty-cycles or even provide sustained long-term operation. 9) New colo facilities will have to face increased regulatory pressure and approval cycles. colo prices will go up, as a direct result of these increased costs. 10) Expect to see the return of the wind-fall profits tax, on a permanent basis. Caveats: 1) If the enviro-nazis get "nuked" tomorrow, this will only change the time table, by a year or two. Energy plants are not built by magic. 2) This entire scenario could reduce energy usage growth to about 1-2%. Usage will continue to increase. Thus, exacerbating the problem. 3) Houston could get "nuked", by the feds. -- MHSC is looking forward to doing business outside of California. :) -- ROELAND M.J.

That was last month's issue. I chuckled too. But, for a small end-point LAN, it's not bad. Consider it appropriate tech, applied in appropriate places.

Most of the data is not verifiable, but a profile of 100-10,000 subnets, between 5-2000 nodes per subnet w/ RIPv1 seems to be emerging for sites like Xerox as well as old NSFnet regionals. On the other hand, reports of large, multinational networks running static routing in their cores seem to indicate a desire to have routing in the core more stable than any dynamic protocol will allow. With the growth in the number of injected prefixes and varient paths, one might say that the "value proposition" of dynamic routing is not what it once was... Or it could be that the folks running the big networks are more comfortable with manual/static routing systems? Such environments certainly provide easier means to set enforcable service level agreements. But my muse has gotten the better of me. --bill

What I hoped the article pointed out was the conflicts between rabid enviro-nazis, no-nukes folks, and California energy needs. Yes, the Sierra Club supported the California Clean Air Act (CCAA). This is probably the most draconian, uncompromising, environmental measure that has ever been passed into law, IMHO. They celebrated when it was passed. Yet, they took no stance on energy deregulation until well after the fact, when it was too late. They helped create the quandry we are in today. That was my point. -- ROELAND M.J.

The Cidr Report
by Tony Bates 28 Apr '01

28 Apr '01

This is an auto-generated mail on Fri Apr 27 23:00:00 PDT 2001 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
