  1. Go All Wireless on Hybrid Community Networks? · · Score: 4, Interesting

    Don't know how much of a Linux user you are but I built a couple of wireless access points/relays for my neighbors that hook up the to the sflan network.

    I used a couple of old junker laptops running Linux. This should be completely scalable to your situation. Here's a link to how I did it. For a relay/access point the same principle applies, just use two cards, one with a directional antenna the links to you, the other with an omnidirectional that serves DHCP. I found that cheapo cards on old hardware works great.

    There are plenty of sites that have intructions for building directional antennas. From my experience you don't need to spend a lot of money for this kind of thing.

    I'm glad your sharing your bandwidth. More people need to do this. Hopefully, one day the Internet will be entirely wireless and free. Free meaning you don't have to pay an ISP, you just buy your equipment and you're online. Just like CB radio.

    Feel free to use my email address at the above site if you have any questions.

  2. In Search of the Big Bang on Books that Changed Your Life? · · Score: 1

    By John Gribbin got me started in science. It's a bit light on the math and is somewhat non technical but pretty much covers the entire history of astronomy, the problems faced at each stage of discovery and how they were overcome.

    For me it was a kind of aventure story whose protagonists were the scientists struggling to understand the meaning behind their observations. And how the next generation always builds on the discoveries of the previous.

    You learn how we began to measure distance in the universe, how you theorize that such a galaxary is so many million light years away, from sodium lines in a laboratory to the composition of the stars, how you deduce everything is moving away from everything else, how a few clever people began to theorectically wind the clock back and apply basic physics principles to deduce a model of the early universe. Fascinating stuff for a geek.

    Again, so much a technical book, but inspiring non the less.

    This is an obscure bug that only occurs with the iptables "tcp-option" and even then the worse someone can do is DOS you and probably couldn't even do that if you configure iptables to drop ICMP packets.

  4. Scant on Details on Broadband Blimps · · Score: 1

    They seem to be more interested in their Stratellite(TM) than the Wi-Fi aspect. I suspect getting their high altidude airship in place will be the easier part of the project.

    Issues not covered on their site:

    What standards, if any will they be using?
    Will it be 802.X or will they develop their own Standard(TM)? Developing their own could be very expensive. And who will make the hardware for it? Will consumers pay the price?

    What about power? The FCC restricts 802 to 100-200mW. If they want more they'll have to "pay off" the FCC and for that they'll probably need $100,000,000+, a very high initial investment.

    Until we see more info on overcoming the bandwidth, interference, and power problems we'll probably have to conclude that this is all hype.

    Your Linux cluster is the cheapest method I've found. I have one such TB box with 10 old/used/cheapo SCSI disks and using software RAID I built about 4 years ago. It acts as a backup server using rsync in a shell script that collects data from 15+ networked servers every night.

  7. Re:use more power on Pushing Wi-Fi's Limits: Problems and Solutions · · Score: 1

    No, you're quite right. I agree. I guess my point of contention is with the FCC. IMHO local communties should decide on power limitations. So for a small town with a few users over a large area it may be more beneficial to use higher powered trancievers than for a densely populated city. But local municipalities should be able to make decisions about how much interference is acceptable through their own elected representatives.

    The FCC's one-size-fits-all model is hindering WiFi's expansion.

    BTW, in the O'Reilly 802.11 book a suggestion is made about speeding things up by disabling the RTS/CTS mechanism and allowing the CA system to handle contention. I guess, as always, experimentation is the key.

  8. Re:use more power on Pushing Wi-Fi's Limits: Problems and Solutions · · Score: 2, Informative

    Yes, but with 802.11g and 802.16 the specs allow for up to 50+Mbps, several T1s. For surfing the net and reading email this is enough to supprort more users than may be commonly found in the limited area covered by the current power restrictions.

    The 802.X specs cleverly implement CSMA/CA, a collision avoidance system that seems to work pretty well. From my rooftop (downtown San Francisco), I can see 150+ networks yet never experience any symptoms of interference.

    Also, in setting the 802.11 limits on power the FCC seems to have overlooked the "skin depth" wavelength/2*pi attenuation factor that limits microwave ranges by a factor exponetially greater than for the longer wavelengths of many cell phones.

    I operate a couple of nodes as part of the sflan project and it would be nice if we could reduce the "line of sight" requirement just a tad by boosting the power, say from 200mW to 800mW.

    It just ain't fair than big bucks phone comapanies can "buy" an FCC license and blast away at 1500W while us folks trying to provide a free community service have to operate with our hands tied.

  9. use more power on Pushing Wi-Fi's Limits: Problems and Solutions · · Score: 2, Informative

    Many of these problems can be easily solved with more power. The FCC has imposed severe power limitations on 802.11 of about 100-200mW per channel.

    If the FCC would allow us amatuers to use, say, half the power that cell phone companies do, we'd be able to Wi-Fi the whole country.

    Give us the tools and we'll finish job.

    From the DOJ anouncement:
    The investigations focused on individuals and organizations, known as ?warez? release groups, that s pecialize in the Internet distribution of pirated materials. Release groups are the first-providers - t he original source for most of the pirated works traded or distributed online. Once a release group pre pares a stolen work for distribution, the material is distributed in minutes to secure, top-level warez servers and made available to a select clientele. From there, within a matter of hours, the pirated wo rks are further distributed throughout the world, ending up on public channels on IRC and peer-to-peer file sharing networks accessible to anyone with Internet access.

    What they describe is a highly efficient and cost effective file distribution method. Society should be embracing this technology and maximizing its potential instead of criminalizing those who use it.

Having glanced through these guides I couldn't help thinking how easy it would be to distrubute spam containing child pornography while posing as your competitor.

    It's ironic that our elected officials can't take on tough issues like health care but seem to have plenty of time to pen 161 pages of rendantly abominable extraneous verbosity.

    We've had the DMCA, now it's CAN-SPAM. What troubles me about these laws is that they're ineffectual. People will copy DVDs and distribute them, others will send unsolicited advertisements to any email address they can get. Relax people. This is no biggy. For the domains I manage I get about 1500 emails/day (webmaster, postmaster, admin, etc.) but I use a spam filter and a procmail script to deal with it.

    What we're asking here is for the government to control what comes into our inboxes. I'm sure CAN-SPAM will be tied up in the courts for years over it's implications on the First Amendment. The whole thing is a waste of society's resources.

  18. We need to work together on Lessig On IP Protection, Conflict · · Score: 4, Insightful

    The essential building blocks of all technology come the pursuit of truth, not dollars.

    I think the general public really believes that money is the sole incentive of technical creativity. I agree money can be a good incentive if you're selling televisions or computers, but the real underlying work that went into the ability to produce these things was done, not for profit, but more because people were compelled by the process of discovery.

    The integrated circuit is a good example. Most of the fundamental research that went into the chip came from a lot of painstaking research in solid state physics and was carried out by researchers in university labs making less than they would working for a Fortune 500 OEM.

    People really are capable of doing things just for fun, because they're interested in them, or just like knowing how things work.

    However, people do need to get paid. But the question here should be, how do we bring people together to create technology? Wouldn't it be great to get all the top cancer researchers together and see if they could make some headway on understanding tumors? But how do we meet their needs, keep them happy, make sure they are adequately compensated, etc.? Though this may be difficult to accomplish under our current economic system, I think you'll agree it's something we need to work towards as it seems to me a much better approach than saying, "we have a pattent system, and if you can find the cure for cancer, you can make a lot of money." This seems so inefficient as comapanies tend to scramble over each other, reinventing the wheel, keeping their research secret and trying to make as much money as they can.

    There's nothing like

    It's so much easier to troubleshoot a missing library or edit some code to fix a problem.

    The documentation that comes with proprietary software is usually lacking. But then the most important documentation, the source, is often never available at all.

    I'm sorry this guy had such a hard time. But I'd stay away from those all-in-one commercial products. There's a reason why sendmail, samba, apache, etc. have been around so long. They may be diffuclt to install and configure but have infinite flexibility
