  1. Re:It's been here for a while on Two-Way Satellite Internet Is Here! · · Score: 3

    It probably isn't as bad as you suggest. You shouldn't be seeing 30 to 40 connections to pages with modern (or at least future) browsers and servers. After getting the HTML, the popular browsers usually open up 4 to 7 concurrent connections which incur the round trip times in parallel and then reuse them for subsequent requests when possible.

    I'm sorry, perhaps I wasn't clear when I said that I installed and used this setup. The particular site we were using was washingtonpost.com, which at the time averaged 50 objects per page. It wasn't the worst site out there (ICQ was much worse), but it definitely wasn't the smallest pagesize.

    Even if you have 4 simultaneous connections and reuse them, you're still incurring large delays. To set up the TCP connection, you need a three way handshake. That is a minimum of 1.25 seconds (given .5 seconds for a round trip). Then, best case scenario, you send a request and get a response for another 1 second of latency, plus any latency present between the satellite headend and the website. Let's assume 40 objects on the page. So each connection has to get 10 objects in parallel with the other connections. So that's 1.25 seconds to set up the connection, and 1 second per image. That's 11.25 seconds of latency per page added by the satellite connection. Theoretically, if you send all the requests at the beginning of the connection, you can reduce that latency. However you still have a minimum added latency of 2.25 seconds, and it's questionable whether or not you can do that with current browsers (I personally don't know).

    In contrast, if you open up a dialup connection to an ISP without caching or compression and pull washingtonpost.com's front page, it will take about 11 seconds to download and render the page. That number is based on a series of tests that I performed personally, using several different computers to make sure the number was accurate.

    Also, if you're wondering where I got a half second for a round trip from, it's fairly simple. The satellite is located 22,500 miles above the equator. Given a best-case scenario with both you and the satellite headend on the equator, that's a one way trip from you to the headend of 45k miles, and a RT of 90k miles. The speed of light is 186,300 miles per second. So that gives a best-case latency of about a half a second.

  2. It's been here for a while on Two-Way Satellite Internet Is Here! · · Score: 3

    It's just that it's not that commonly used. I installed a bidirectional, mobile satellite internet link 2 years ago, with T-1 speeds. Granted, not the cheapest thing to do, but it was still there. And it sucked, at least for web surfing, which was why we installed it. Unfortunately, we didn't have much of a choice since we needed a mobile solution, and Ricochet wasn't up to speed yet.

    Typically, satellite data streams have about a half second latency. That means you send out a ping to your next hop, and it's at least 500ms before you get the response. Now when you're doing a stream of data in, this isn't so bad. You have a half second latency when you're setting up the connection, but then you have a nice even data delivery. However, for things like web surfing where you're setting up lots of connections (up to 30 or 40 per page sometimes), it's unbearable.

    Satellite internet connections are useful if you're in a remote area and can't get anything else. But if you have anything else, even IDSL, you're going to find it a better choice for things like web surfing and gaming.

The assignments of users to IP addresses are mostly done by round robin, not by location, since all the dialup connections are backhauled to AOL's datacenters.

    The closest you could nail down an AOL dialup IP is to the datacenter. To get any geographic information on a user, you'd need to have access to AOL's internal databases, and they won't even give that to partners.

Basically, everyone involved with blocking spam, or opt-in (real opt-in, like MyPoints) advertising systems got together and talked about the technology. @Home did a big presentation on anti-spam things which happened to include some talking about their policies on people running servers.

The exec from @Home giving the presentation said very clearly that they don't routinely check for servers (excepting NNTP proxies, since they had that little problem with the UDP this past winter), and they really don't care if people run them as long as they are not causing problems. He defined problems as taking up too much bandwidth, or causing a security problem for @Home itself.

    So I really don't think this is a cause for concern. I doubt they're gonna bother checking for these things (they'd have to sniff the network constantly...

    Yes, it is a semi-informal site. It's an internal site, for AOL employees. This is not a site that was designed to be used by anyone outside the company, and the people who put it up are not web designers. The "confidentiality clause" at the top is not legalese. It's a reminder. Everyone who has access to view office.aol.com websites has already signed either NDAs (in the case of on-site vendors), or employment agreements that contain much stronger language.

    Why not just port the client to Linux, and put Linux on these appliances? No license fees for the OS, and the interface, to the user, is pretty much the same. That's what they've done.

    I saw the Netscape plugin portion of the Tokyo project work when I was still working at AOL. This was probably about 6 months ago that I first looked at it, and it was pretty slick then. Had a few bugs, but it was good for an alpha. I never did get to Gamera, even though I heard a lot about it. Mostly because I never took the time to download it off the internal servers.

    IIRC, AOL was moving towards using Gecko in the clients (and therefore Netscape/Mozilla) instead of IE. Most of the holdups were concerns over the agreements with MS that keep AOL on the desktop of fresh Windows installs. However, I seem to remember that as I was leaving, they sorted it out and were pushing ahead. Although, it was always discussed as making an interface to plug a third-party browser into AOL, and never about Netscape/Gecko specifically. But I didn't live in that part of the AOL house, so I could be mistaken.

    Until now, a major problem with semiconducting polymers has been that they oxidise and become discoloured when exposed to light. CDT has previously only been able to make green monochrome video displays. Now, CDT claims the red, green and blue LEPs in its new display are the first to have lifetimes long enough for use in consumer products. CDT's red LEP will work for 100 000 hours, green for 30 000 hours and blue for 1000 hours. But the company isn't saying how it has achieved these improvements.

    "Seiko's research in Japan shows that a cellphone will only actually get 200 hours use per year," says Burroughes. "People replace their mobiles well before the current blue polymer lifetime of 1000 hours is reached." And further improvements in LEP lifetimes are expected, Burroughes says.


    OK, so the display's only good for 1000 hours. I don't know about the rest of the world, but I keep my cell phone turned on 24 hours a day. So, if I do the math...

    1000 hours / 24 hours per day = 41 1/3 days.

    So it looks like I'll have to replace my cell phone every month and a half if it uses one of these displays. Doesn't seem that useful to me. Maybe they could have a red "screen saver" mode that would just use the red display elements unless you needed full color. That would at least give it a little better lifetime, since then their assumption that a cell phone is only "in use" 200 hours a year would be a little more valid.

    However, I still think that a display that is only good for 1000 hours of use is probably not going to be that widely used at all. I mean, sure, the rest of the crowd here is talking about a lot of neat things:

    paper thin TVs - How many hours of TV do *you* watch a day? More than 3? Then this display is dead in less than a year.

    digital wallpaper - Do you really want to re-wallpaper your house every month and a half?

    If the technology is cheap enough, then sure, it can be used for things like an electronic newspaper. I would really like to see that, actually. I'd pay $100 a year (assuming non-continuous usage here) for a thin, flexible display that gave me up to the minute news. Of course, you still need something to drive the display, and then you might be getting into something bulky. But the ideas are there.

The device has to be activated by a signal (transmitted via satellite) from Lojak's control center, and they won't do that without a police report being generated. Once the device is active, it emits a tracking signal which the police can use to find the car.

    Second, GPS. GPS is a system by which you receive signals from a number of satellites with a timing signal. By knowing the locations of the satellites and the offsets of the timing signals, you can figure out where you are. The requires LINE OF SIGHT to the satellites. Too many buildings or too much heavy foliage, and GPS is useless.

    So GPS would be useless in a laptop like this. One, you'd have to have an antenna on the outside of the case. Sure, you could blend that in the with case, but that's the least of your problems. Keep the laptop under cover, or in a box, and the GPS unit can't determine where it is at all. Plus, GPS has a built in error (for civillian purposes) of anywhere from 50 to a thousand feet (IIRC), depending on what mood the military is in that day.

    OK, so Lojak. Lojak relies on the receipt of a signal from the satellites. Keep the Lojak device in a suitably shielded area, and it will never receive that signal, and even if it did, the transmitted signal would never breach your shielded perimeter. Now it's not a trivial matter to get a car shielded like that. However, a lead-lined laptop bag should work nicely.
