      Shut up about porn.

      Interesting comment. Allow me to demostrate why we all owe a debt to porn, and the people who enjoy it.

      Back when VRC's first came out, they typically ranged from $1200 to $1800 each. The reason you can buy one for $49 now is because of porn and those who enjoy it.

      When video cameras first came out, they were the size of suitcases and cost in excess of $3000 each for mediocre quality. Now you can buy an exceptional quality unit for well under $1000, and get a decent model for closer to $500. This is because of porn and those who enjoy it.

      When computers first came out, growth was slow and mainly due to business' wanting to automate. Once computers became powerful enough to be useful for full graphics (386dx) they were still terribly expensive ($2000 for a stripped box) but soon came down because of porn and those who enjoy it.

      When the Internet first became available to the general public, in mass, I personally paid $80 a month for 80 hours. (ironically, not for porn, but for a BBS). Many before me paid much more. But now you can get dialup for $10 to $20 a month, because of porn and those who enjoy it.

      Like any new technology, the price can only come down once two conditions are met:

      1. Demand is high enough at inflated prices to pay for the research and development involved in bring out a new product. This allows a company to recover a portion of their original investment.

      2. Demand has to be reliable enough for companies to invest in excess manufacturing capacity. This lowers prices because it introduces economy of scale. It introduces competition because any profitable venture will attract capitalists who want to make a better mouse trap, cheaper. Eventually, it turns the new product into a commodity, where margins are razor thin and you can get the same basic product from a number of providers.

      In each case, it was porn and those who enjoy it that invested the money on the consumer side for these products. No one would have paid $3000 for a computer to email someone on a $80 a month 2400 baud connection. (think fidonet or google it) No grandmother would have paid $3500 for a video camera to take shots of her grandchildren, to play on her $1800 VCR.

      Microwave ovens became available in the 50s, but they did not become popular until the late 70s. Why? Because they have no porn value, so it took 20 years to get the economy of scale and demand strong enough for the price to come down. Had there been a potential porn use for the microwave, we all would have had them for $100 before we landed on the moon.

      We all owe a great debt to those brave pioneers, who worked tirelessly typing with one hand, pants to ankles, in the darkness of night. Because of their relentless pursuit of a better way to masturbate, we are all able to enjoy consumer goods at incredibly cheap prices. Even the third world countries are able to benefit with wireless phones where there are no wires, all because some guy sitting in his parents basement was patient enough to wait for a 256 color GIF image to load to screen over a 14.4kbit connection.

      So, the next time you see a pervert, go up and shake his hand, and tell him "Thank you for your contribution to society".

      Just be sure to wash your hand afterward.

    I still want to get off of dialup at my apartment. And even when I had broadband, there were still sites that wouldn't load very quickly. The servers are going to need some upgrading as well, I think, before bandwidth becomes the only bottleneck. Still, that's really cool. I hope to see something approaching instant response within my lifetime. Besides my old DOS computer, way back when. :)

    It's time to face facts. "Broadband" isn't, and won't be, until we're at least at the 1 Gbit/s rate to the home. In fact, with gigabit cards starting to become affordable, and with home networks on the rise, a gigabit link to the house may not be fast enough in only a few years.


    Running a modern PC over so-called broadband networks is like towing a Ferrari F1 car using a couple of Shire horses. Sure, it "works"...


    For the money so far spent on rebuilding Iraq, the US Government could have built a network of 2 terabit lines between every pair of States in the US, installed the clusters of routers needed to handle the load, and provided lines to every carrier of Internet and phone traffic in the country. They'd probably still have cash left over.


    This isn't to say we shouldn't rebuild Iraq. This is very much to say that if organizations and Governments can throw that kind of cash around as though it were spare change, then I'd really like to see some serious infrastructure upgrades in a certain country whose economy and security both need those upgrades to take placed.

    Steven Low [caltech.edu] of CalTech's Netlab [caltech.edu] gave a talk [mit.edu] at MIT yesterday regarding the modified TCP protocol they used to achieve this transfer. Those who are curious about the details can check out the Fast TCP [caltech.edu] homepage.

    Basically they showed that conventional TCP is not very good at scaling to large flows like the ones in the article. He described a typical broadband Internet connection as being able to utilize only about 27 percent of the available bandwidth, while their modified FAST TCP connection reached 95 percent efficiency. He had some nice test results showing how the protocols reacted to having to share bandwidth with other flows, and pointed out how when other flows finished and more bandwidth opened up, conventional TCP was very slow to take advantage of the increased bandwidth.

    There's an older Economist [economist.com] article describing the protocol in more detail for those who are interested.
