- OS overhead on each end - transmission time (getting the packet onto the wire at each hop) - propagation time (getting the bits down the wire) - queuing delay (waiting for the preceding packets to get through)
A congested link is a link that's dropping packets because it's full. Queuing delay is normal - yes, there's more of it on a congested link, but there will be some queuing delay (on average) even if the link is only 0.001% utilized.
You WILL see an decrease in ping times with multiple connections unless there is ZERO traffic aside from your ping.

articles like this do beg the question of whether or not advertisers are paying to have the products promoted as a Slashdot story
As someone who has sent a product to Slashdot for review, let me tell you that this is *not* how it works. These guys like gadgets, and they consider product announcements to be worthy of "news for nerds". Judging by the number of comments attached these stories, most slashdot readers agree. That's why you see a lot of MP3 and PVR related stories.
We didn't pay slashdot to review the SliMP3. All cmdrTaco got out of it was a free prototype. I wasn't even the one who submitted the original story about my project. Somebody just found us on the web, and submitted a story. That's usually how slshdot works. If that weren't the case, you wouldn't see the slashdot effect - don't you think sites would prepare for the traffic if they knew a story was coming out?
Contrary to whatever you've been led to believe about the patent office, you CAN get a patent on absolutely anything - it doesn't even have to work. The patent office just files the paper work. It's not until you sue (or get sued) that anybody decides the strength of your patent.
Not that Disney execs are necessarily avid Nielsen readers. Disney Sites have some of the worst navigation. Take a look at Disney.com, for instance:
I was of the five web designers at Sun Microsystems who did the first site for disneyland.com, back in 1996. The site hasn't changed much since then - very little text, cluttered menus, silly clickable Java animations. This is what they wanted. The artwork we received from Disney was crap. We'd actually go to other Disney fan sites on the web and steal their gifs! (Technically, we were just stealing them back since it's all (c) Disney).
It was still a lot of fun though - when the site was finished, they flew us all down for a VIP tour. We met Michael Eisner, he showed us Walt Disney's appartment, we rode Disney's private car on the train. Fun stuff...
Oh, and we had a quad-processor Sparc server just for vi.:)
The data for each experiment was equivalent to 35 times the information available in the Library of Congress.
The Library of Congress was an interesting comparison back when CD-ROM drives were first becoming popular 10 years ago, and laymen had no clue about the storage capabilities of computers. Now it's just plain stupid.
Imagine if hard drives were specd in KLOCs - thousands of libraries of congress.:)

he wants to go back in time and warn his father, who died of cancer when he was 10, of the danger of cigarettes.
He died at the age of 33!! I've never heard of smoking killing someone at such an age. As a 23 yr old smoker myself, that scares the shit out of me. I could be half way dead already.
I'm getting good at quitting though - done it 20 times already today!
BTW, the stated viewing angle on these is 170 deg, and they darn well mean it. Comparing (e.g.) a laptop LCD to these is wholly inaccurate -- not all LCD panels are created equal these days.
Any decent laptop screen is **DESIGNED** to have a narrow viewing angle, so the guy sitting next to you on the plane can't read your document.
I had some time on my hands once, so I drove from San Jose to Portland to New York to San Diego and then back home. Oh yeah - and a quick visit to Tijuana, for horse tacos or whatever they put in them. Total miles 7K+ in 10 days (I stayed at each stop for a day or two - other than that it was solid driving).
I'll tell you folks, there ain't that much to see from behind the wheel of a car. It's mostly grass. Anyone who thinks the US is overpopulated has probably never left their home city.
Anyone remember the 60 minutes Audi 5000 scandal? Where the car's fuel injection system was said to, in rare cases, cause the car to accelerate out of control, causing injury or death?
I heard about that - it's a load of bull, if you ask me. Next time you're in your car, try mashing the brake while giving it full throttle. I don't care what kind of car it is, the brakes ALWAYS win.
Now with this CD from Sony Music I am unable to use my Sony PC Link to enjoy this music I have (hypothetically) purchased using my Sony MD Walkman.
CLASS ACTION LAWSUIT!
Normally I hate these - lawyers benefiting from 100,000 people suing because they lost $0.10 due to their light bulbs not lasting as long as the manufacturer claimed.
However, this is a blantant lie on the part of Sony. I say sue - even if lawyers get all the money, it's an effective punitive measure. Fuck these assholes at Sony.
Yep - since back when Linux was still a play thing. For the first 6 months or so, the servers ran Solaris - big mistake cost-wise.
One of these machines is a dual PII/400 Whatever.
I said "is", not "has been since 1995", you dumbfuck. BTW, you may be astonished to learn that the latest 2GHz machines are total overkill for most web sites serving <5Mbps, which is why I haven't had to upgrade since the PII days. I forgot to mention... BSD is *fast* too.
Was BSD Dying in 1995 as bad as it is now?
Clearly, no. Look at the numbers!
I run linux on my desktop, where I need bleeding edge hardware support and the widest software compatibility. For the servers, FreeBSD has never let me down. You should give it try.
I've been running two FreeBSD systems for over seven years each. I've had to do a grand total of *ONE* reboot that I can remember, aside from powering down to swap hardware, update the kernel, or to move the equipment.
It's a damn stable OS. One of these machines is a dual PII/400, serving 700-1000kbps day in day out, with hundreds of active TCP connections at any given time, starting 15-20 new processes per second. The other machine is for a single, fairly busy web site doing 700kbps traffic.
FreeBSD is rock solid. I have absolutely no need to plan for a kernel panic.
There are tons of words like these, but "inflammable" is a little different. It's the '-able' suffix with "inflame". The "in-" doesn't mean "not", or "un-". Inflammable basically means "able to go up in flames." I'll give these guys a break though, for the.ch domain.
Hell, this is exactly the kind of device that serious climbers, hikers and backpackers wear on purpose for exactly that reason - they want to be found if they're injured!
Sure... if you happen to do your serious climbing and hiking within a few miles of a cell tower. How's your reception across those 1000 acres out back?
Never sign a contract for more than one year on a leased line, or 6 months for colo.
I ran an ISP for about three years, until around mid '99. It's not my main business any more, but I still have a couple of hosting clients for high bandwidth sites. the ISP business is TOUGH. The competition is insane, so the approach most ISPs take these days is to advertise really high prices while offering competitive rates only to those who haggle and know how to shop around.
Here's what I've been spending, year by year on Internet service. I've switched providers several times over the years due to changing needs wrt colo vs leased line, and varying costs. I've now been with Hurricane Electric for over a year. They are outstandanding, but you'll have to haggle to get a good price.
1997-1998 - 3 bonded centrex ISDN lines from Brainstorm, 384Kbps: $750/mo 1999 - shelf and 1Mbps at Above.net plus a ptp T1: $2000 + $450/mo 2000 - shelf and 1.5 Mbps at maxim.net: $700/mo 2001 - ptp t1 to Hurricane: $650 ISP, $350 XO for the line 2002 - shelf at Hurricane and 2MBPS: $650. PTP T1 to my shelf: $350
As you can see, over the years the cost of connectivity has fallen from $1822/mbps to about $500. That's not just per MBPS, I'm talking about a complete package - remote connectivity for 1-2MBPS upstream.
The cost of installing fiber is still outrageous, but the fluctuations in demand have resulted in a surplus of strands in the ground. I've coordinated fiber installations before - trust me it's a BIG deal. Trenching, conduit, permits, dealing with the city and the fscking retarded telcos. It's no fun, it's EXPENSIVE, and it can take upwards of three months just to get 100 yards of fiber in the ground. But now that the fiber is there, ISPs and telcos can start using it as soon as there's demand, just by connecting the needed equipment.
Also don't forget that the same strands can usually be used for OC3, OC12, GigE, etc. So it's not just that there are unused strands in the ground, there is also a ton of equipment that can be upgraded to increase the capacity of the strands we're using.
Bandwidth costs still have a long way to fall!

ping time is the sum of:
- OS overhead on each end
- transmission time (getting the packet onto the wire at each hop)
- propagation time (getting the bits down the wire)
- queuing delay (waiting for the preceding packets to get through)
A congested link is a link that's dropping packets because it's full. Queuing delay is normal - yes, there's more of it on a congested link, but there will be some queuing delay (on average) even if the link is only 0.001% utilized.
