I wrote up a tidy post on how to do this with a Cisco router, but Slashdot insists it has "Lameness". I say Slashdot has Lameness, and I will now go away for another couple of years. What a bunch of self stimulators...
The Earth was cooler from 1940 to 1970 - this was due to diesel engines producing sulfate aerosols, which are highly reflective. Right now we gain about 4.0 watts/meter^2 due to CO2 and methane, but we lose about half of it due to the sulfate aerosols still in the stratosphere. The cleaner burning fuels we implemented in the 1970s resulted in lower amounts of that stuff in the atmosphere, hence the reversal of the cooling (dimming, actually) trend.
Let me put in a shout for TreasureTrooper - no adware, but mobs of dorks are spamming YouTube video comment streams on their behalf... viral marketing at that level needs to be excised just like any other unnatural growth.
Preach it, brother! If you want a no bullshit assessment of what is going on stuff gets pretty deep at RealClimte, but those guys do not fool around - nothing but the facts.
I run a little network engineering company. We're getting some customers who want 24x7 service and I think if a few of them sign up I can afford to hire a couple of guys in Romania or India to provide night coverage. We'll pay 'em good, they'll get some of our R&D work, and we're free to expand further. Life is good.
Some outsourcing to India will succeed. Some will fail. You cheered when the internet provided you Japanese bondage pr0n, now you get to suck it up when it lowers your wages. Seems a fair trade to me...
You say lawyers are cheaper, I say not - you can shoot back if someone is trying to hold you up, at least in this state, but look at all of those manufacturing jobs that have left the U.S. You think that is U.S. politicians? Nope, its product liability lawyers chasing the business out of the country.
There are three quality of service models for the IP protocol. We currently use a best effort internet; "Hail Mary, full of grace, may this packet arrive at its appointed place within its appointed time window". This is like ethernet - an unworkable theory that is just fine in practice... for data.
Differentiated services are the next step. Some traffic is more important than other traffic. If all ISPs did were to priority queue RDP (realtime data protocol) VoIP would work most everywhere and life would be good. I'd award bonus points and spend money with an ISP that would allow me to set the traffic to be accelerated from their side. I don't think this is workable at the DSL/cable scale, but it already happens if you've got enough traffic to justify an MPLS (multiprotocol label switching) T1.
Integrated services actually let you use RSVP to reserve bandwidth for given applications. This is complex to implement and it doesn't scale well. Some carriers are starting to use this in conjunction with something called pseudowire to allow legacy TDM and ATM transport across on IP cloud. Again this is a big ticket purchase and transparent to the end user.
I'm very willing to deal with an ISP that charges more for a differentiated connection... as long as traffic requiring realtime treatment is what is accelerated as a minimum, and I'd be even more excited about one that would allow me to set output queue policy via a web interface. The first part is easy, the second part... well... I'd say you have to own a small ISP to make that happen, but I can dream...
You can download most any current Cisco exam, cram it, and become a 'professional'. I got my CCNP and CCDP the old fashion way - worked, studied, worked, studied, worked, worked, worked, recertified, completed three of four exams for the CCIP, worked some more. Now you can just download 'em. Cisco resellers are required to have people with certain levels of different things and most jobs I see wanting Cisco qualify the position based on the ticket you need to have to get it.
I've taken my first halting steps towards studying for the CCIE. Those words are in italics because I feel like I've just typed arranging a circle jerk every time I use them. There are so many guys six months into the process with no real skills and none of the talent needed who are circle jerking on their theoretical CCIE. Or worse, the guys who are six years into it, they've got their whole self esteem invested in getting those four letters after their names, and they just don't have what it takes. Its sad to see.
Whatever the case, CCIE still has value, and my job puts me in front of everything on the exam except multicast and I'm slutting about taking multicasting jobs at half of market rate just so I can tune up for that area.

A WIC-1DSU-T1-V2 is $1,000 list, $700 or so to a small reseller in distribution, and $400 for a clean used unit from a reliable aftermarket dealer. Go look for that part number on Ebay and check out how new boxed product is 15% of list price... this stuff is everywhere and it basically drove me out of the Cisco aftermarket.
I was in San Jose for the VON show last week. I met a VC shopping for used network equipment vendors. Having worked in the aftermarket for a while I'm flat amazed that someone wants to consolidate aftermarket companies.
NASA knocked the cover off the ball with this one - 800 days on equipment meant for 90 is a big win in my book.
I'm with you on the politics and ISS. We should cancel the shuttle, distribute the money evenly between Scaled Composites, Space-X, Bigelow Aerospace, and Virgin Galactic.
Right now the U.S. intelligence community is hamstrung by having to deal with something like 80 congressional committees for its funding. It is a national priority, the failure of which got 3,000+ civilians killed, but its not enough of a priority that we actually DO something about it.
Call or write your Senator today and indicate your support for streamlining their funding.
I would personally prefer to write simply and directly about areas in which I have knowledge, but experience with Slashdot has shown that for better or worse, a mob of uninformed anklebiters will get all over any informed poster with a bunch of nonsense comments. I open and close posts here with the flat of my hand and this practice limits my responses to people with an acceptable cluon flux around them and the occasional one line "Gee, aren't you special" response. This isn't perfect, but its a dramatic improvement over the way things used to be.
This is Slashdot, cap'n, and I'm ahead of 99 and 44/100ths of posters when I respond before reading a Slashdotted article because I work in the area. I swore off ever reading Slashdot comments again about a month ago but this one was just too juicy to let pass. The whole place would be ever so much better if people who knew things posted and those who didn't either remained silent or posted well considered questions.
The 1,965' tower fall was at KDUH in outstate Nebraska, about 400 miles west of me. As I recall the guys had been improperly tensioned for an HDTV antenna placement. The climbers were about a quarter mile above the ground when it all let go. One of them was 25 and his 18 year old girlfriend was on the ground near the base and had to simultaneously run for her life and watch her boyfriend die.
KDUH. Almost seems like an Encyclopedia Dramatica article, doesn't it?
Less famous is the second event in Nebraska that year - an injury to one of two climbers putting up a 'gate' - one of those triangular stand offs for antenna spacing. The gate caught during the lift phase, it was 'loaded' and stuck against the tower, and the guy who broke it free was rewarded with a nice, solid hit that shattered his right arm. Mmmm climbing one handed in agony... my idea of a good day at work. This wasn't the final blow that put Media Integrators out of business but it did put them out of the tower construction game.
Not long after that a skillful bulldozer operator in Glenwood, Iowa, half an hour south east of Omaha scored a confirmed kill, hitting the top guy wire for the 300' city/county tower, neatly snapping it in the middle. Most of the equipment on it survived the folding, then was destroyed when they cut it and let it fall; cranes cost and there were safety concerns - easy to load a guy with a tow vehicle and torch the base.
Not long after that one of the 1,200' towers at Crown Point in Omaha came down during the night. Amazing it didn't damage any of the other three when it fell. The replacement is up and its quite strange to see three properly painted red and white towers and one new galvanized one.
We've got a bit of a pool going here - will the next fall be the 80' Rohn 25 half a mile east of the I-80/I-480 interchange that is so corroded one of its legs has a inch and a half air gap between tower leg and base, or will we see the badly overloaded Metro Transit Authority tower directly south of that interchange come down with two inexperience climbers on it?
I want you slobbering wireless fanboys to listen carefully.
Used towers are dangerous. You can get stitches and broken bones handling one 10' section of new Rohn 25 if you don't have competent help. A fall from 6' can be fatal, a 'lucky' fall from 20' is still going to leave you with a lifetime of disability. Towers are not a permanent fixture. Even with care they rust and they get metal fatigue if they're not properly braced or guyed. No professional will reuse tower components without a careful visual inspection and most will just say no unless its the smallest cross section segments like Rohn 25 (12" face) and they're not going back up in a large configuration.
If you get it down and home with all of your toes and fingers intact you've still got to get it erected. A proper base is an art - see a prebankruptcy Rohn catalog for details. You need to calculate the wind load for the size of antenna you'll use and make sure you're using appropriate guying or bracing for the given load.
The tallest building I've ever had to service was 634'. The tallest facility I've ever had to manage was 485'. The tallest tower I've ever personally climbed was 300'. The tallest I've ever specified myself and helped install was 60'. The tallest water tower I've ever worked was 135'. The most I've done in the last year was an install at 55' on a 185' Penrod 30. The only experience I don't have is dealing with cylindrical cellular type towers.
Stating my experience should shut down the cantenna artists who just became tower recycling gurus by reading that article twice, but I'm at a loss as to how to say this so that I won't get someone saying "Aren't you special?". I am special in the scheme of Slashdot, because I talk about things I do rather than things I fantasize about doing.
So much for my resolution to never, ever respond here again.
But I'm in better shape than you since I generated a paragraph sized post with content, as opposed to a one line troll with metacontent. Do you have a point? Were you planning on sharing it?
Maybe I'm getting grouchy in my old age - see parent for details. This is how real men connect to the internet:
There are three ISPs in the world - Sprint, UUNet, and [other]. Get on the phone and order a T1 from one of the two real ones. They'll get your payment information and then someone will ask how many IP addresses you need. Tell 'em you want a/24 (256 addresses). They'll ask why, you tell 'em you're going to multihome.
Go to ARIN.net's site. Figure out how to get yourself an autonomous system number. Call up the other ISP you didn't originally order from and get a circuit from them. No IP addresses required, we'll just use the block from ISP 1.
Assuming you're using a Cisco box do the following:
router bgp [your AS number]
network [your shiny new/24]
! UUNet
neighbor yadda yadda AS 701
! Sprint
neighbor yadda yadda AS 1239
And *poof*! Your little/24 is now globally visible via two different ISPs. Yank the T1 to one of then, life is funny for a bit, then you're running like nothing ever happened.
Take this little story and abstract it a bit - there is no 'backbone' to be found on the internet, just a web of large carriers with all sorts of peering agreements with each other. This won't happen at the home DSL router monkey level, but the diverse internet the asker speculated about already exists and happens to be pretty resistant to fools trying to monitor it.
Wow, its as if the drooling wireless fanboys suddenly discovered life beyond an IP address assigned via DHCP. Please pay attention, children...
The internet is composed of 'autonomous systems' - each autonomous system or 'AS' has one or more netblocks of a/24 or larger in size. Each AS connects to at least one other AS, makes at least one netblock available via BGP, and thusly the internet is stitched together. Find this shocking an incomprehensible? Try this
telnet route-views.oregon-ix.net
follow your nose through the login procedure, then type 'show ip bgp [your IP address]' and see what it says. Oh, if your IP address is 192.168.x.x, 10.x.x.x, or 172.16-31.x.x and you put that in please step away from the computer now and ask someone with a clue for help.
I mean really - *this* is a frontpage story? I swear I'm going to auction my low Slashdot ID number on Ebay one of these days and alias this site to memepool in my hosts file.
I voted for Bush because I was sick of Clinton's zipper going up and down. Body bag zippers go one way and they take a lot longer to close since they're about six feet long.
Powell is in a quantum state right now - either irrelevant, or not. We don't know until he decides what to do next. If he retires, irrelevant, if he runs for something he has to disavow the whole deal. The fact that he didn't come back for the president's next term communicates his displeasure in this matter and people know that.
Yes, cowards! You should bravely purchase diesels!
All kidding aside, diesels are more energy efficient than gasoline, the fuel is more easily produced from plants or waste than ethanol is, but a hybrid is a better choice still, no matter whether you're running gasoline, ethanol, or diesel as its combustible.
Diesel has another hazard no one likes to consider - low sulfur fuels are cleaner, but the machines still produce particulates. Snow albedo in urban areas has dropped to 80% albedo from the 97% reflectivity show displays in remote areas. It only *looks* white... this isn't much of a 'forcing' like carbon dioxide or methane, but it is one of the inputs to global warming.
I hate to burst in on your ignorance here, but weather does not cause climate, climate causes weather. The temperature in Anchorage today is not very interesting to a climatologist, but the daily high and low over the last hundred years might be.
