  1. Re:"Free upgrades" on AT&T Wireless Phone "Upgrades" Aren't · · Score: 2, Informative

    TDMA is time division multiplex architecture (I think.)

    It's a 2.5G technology allowing for some serious latency and correction for doppler shift and almost 1.2 seconds of delay between packets, fairly well.

  2. Re:You Think Laptop Heat Dispersion is Bad? on Matchbox Sized Color Projectors? · · Score: 1

    That's................nothing.

    A laptop dissipates upwards of 60w directly into your lap...your cell phone battery that warms up while talking, is probably about 4w of heat -- if even that. The battery is 3.3-some V, which means its pushing just over 1.2A of current.

  3. Re:V.150 Modem over IP on VoIP Solution for Faxing? · · Score: 1

    That's actually a very good idea...what's it going to be, a "virtual modem" device where you "dial" the IP or hostname?

    I think that could come in handy.

  4. Re:Oh, oh yeah? on Space Elevators Going Up · · Score: 1

    I'm sure any security on it would be insane -- think a squadron of fighter jets circling overhead at all times.

    Or, a massive brigade of SAMs...anyone within 100 miles, except for like 1 specially authorized flight of something or other, would be allowed.

  5. HDTV on Peripherals for the Visually Impaired? · · Score: 3, Informative

    Many HDTVs accept component inputs, and can be connected to a computer and configured to work in that capicity.

    640x720 or whatever...and the higher resolutions.

    Go with that.

  6. Re:bluetooth meet wifi on An Introduction To Wireless USB (WUSB) · · Score: 2, Informative

    You can run absolutely anything to want over WiFi.

    WiFi is the lowest two layers of the OSI model: The physical layer (the radios) and the datalink layer (CSMA/CA)

    Anything else is software. Network layer, and so on.

    Thus -- you can run anything that runs over Ethernet, over WiFi.

    1 miles per Watt = 1 609.344 m-1 kg-1 s3

    technically, you're not getting 1600 miles per watt.

    1 watt = 1 joule * 1 second

    1 joule = 1 newton * 1 meter

    1 newton = 1 kilogram, 1 meter per second per second.

    You're getting 1600 meters...1.6km...about .7 miles.

  8. Re:Not a new idea on Storing Light In Chips · · Score: 2

    There once was a man who would stand outside his house, staring in the windows, for hours a day - even in the rain.

    About ten years before, he had special light-delaying windows installed. Guarenteed to provide 10 years of sunlight from the tropics inside the house.

    His family was killed in a tragic accident. Staring in the windows, he was able to see images of them, the delayed images light, going about their business, inside his own house.

  9. Science Fiction on Singularity Sky · · Score: 1

    Science Fiction doesn't have to mean fictional technology. It can mean realistic technology, used in a very fictional way.

    i.e.: "Brave New World" is arguably Science Fiction. Except, all the technology in it, we have now, and then some (For the most part.)

    Equilibrium, has mostly standard technology, save Prozium, but it is still a science fiction movie.

    Just because it's not set in the future, or not set in the future with wicked-cool space ships and gunfights, doesn't make it not science fiction.

  10. FCC regs on Intel to Increase Linux Support, Release Centrino Drivers · · Score: 3, Insightful

    It is likely that Intel cannot release an OSS driver, if the driver itself controls a large portion of the radio hardware. This is probably the case, in situations I've used Centrinos -- the CPU useage is notibly higher when using the WiFi hardware then when not.

    Software access to the radio control portion of the system would mean users could adjust the frequency and power output of the system -- something which would run them afoul of FCC regulations requiring that equipment of this nature be fixed and not changeable by the end user. And, the FCC would not take kindly to this. Both Intel, and the modifying user, could be liable.

  11. Class-Act. Good. on More on IBM 75GXP Drive Fiasco · · Score: 1

  13. Portability on What Kind of Tablet PC to Buy? · · Score: 2, Interesting

    I really can't wait for wearables to become mainstream.

    I would pay $thousands for something that slipped over one or both eyes with a decent amount of transparency (i.e. 80% transparency for the background and 25% for the active window) which took input from speech recognition and a cell phone keypad for data entry.

    There are too many situations where it's impractical to bring a laptop with me, and sync issues with PDAs annoy me.

    Thanks for the warning! I don't really want a lawsuit down my neck any time in the near (or far) future.

    If I can get a goahead from someone (maybe an off-the-record lawyer, or a paralegal or something) saying it's okay to post the comments without the code, I'll put them up on a site for everyone to look at.

  16. Re:Planck's constant on Danger Of Strong Electromagnetic Fields · · Score: 2, Informative

    I think a better number to use might be the Permittivity of Free Space? (epsilon sub zero)

  17. Re:What happens to the paint? on Smog Busting Paint Breaks Down Noxious Gasses · · Score: 1

    A catalyst does not take a part in the actual reaction, but instead provides an alternate path with a lower activation energy for the reaction to take place.

    Thus, the NO2 decomposition reaction is more readily able to take place -- but the NO2 toxins are not absorbed by the paint itself.

    That's why you generally don't have to replace catalyitic converters on your car unless you mess them up, i.e. by doing bad things to your engine.

  18. How about an alternate? on Learning Computer Science via Assembly Language · · Score: 2, Funny

    Just learn C instead. It combines the readability of assembly with the ease of use of assembly.

  19. good. on Congress Eyes Whois Crackdown · · Score: 1

    I strongly agree with this.

    If you own a business with a physical location, you're required to register it. This is part of public record.

    If you rent a house, that information is available, although not quite as public. (think credit reports.)

    If you're renting space on the Internet, you should be required to make a matter of record your real identity. End of story.

    This would eliminate quite a few scams and such by people registering sites with false names, taking money, and closing down.

  20. HD Capture on Digitizing VGA? (take 2) · · Score: 1

    A VGA signal is very similar to a 480p HDTV signal. 640x480.

    You could get an HD capture card, put it in a mini-ITX box, and write an app that captures from that card's video input (x) times a second and displays it on its internal server.

    Not quite a "dongle" but same idea...except a little larger.

  21. wow on Using Single Apache SSL/Non-SSL in Production? · · Score: 2, Interesting

    You sir, are in the exact same situation I was in just two days ago.

    My conclusion:

    Moving to one process to serve all requests, SSL and non-SSL, is more of a hassal than it's worth.

    SSL and Non-SSL on one process requires IP-based vhosting. If you're using vhosts you probably don't have multiple IPs per server. Thus you must use name-based vhosts, and SSL gets confused.

    I gave up and installed two processes and am very happy with that solution.

    Apache+OpenSSL 2.0.48/Win32 on Windows Server 2003.

  22. Re:You can't -- email is heading towards whitelist on Removing Site from Spam Filters and ISP Blocks? · · Score: 1

    BellSouth's mail servers accept relay from IPs on their network...so I just configure my private server to relay through their server for all messages.

    What's the problem with using SI units for everything?

    They're standardized in the scientific community and have units for *Everything imaginable.*

    No real reason to not use them except people don't want to change.

    I'm quite comfortable using metric for lengths and semi-comfortable with temperatures...weights and masses however, I don't have a great grasp of.

  25. Re:this is not whitelist. on AOL Tests Sender Permitted From / E-mail Caller ID · · Score: 1

    eh, yes, it is a bit of a problem I suppose.

    My IP block for my personal email server (jkoebel.net) is blocked from relay to just about everywhere by the dynamic IP blocklist. So, I just smarthost it and relay through my ISP's mail server. It's allowed because I'm on their network, and then the message is originating from a more legitimate mail server == no more blocks.

    If SPF is implimented client-side it might be better, that would allow messages to be flagged "source does not match the known provider address" or something. But who knows, I'm not an expert on the subject.
