Slashback: Privacy, Spectrum, Location

Slashback tonight brings you yet another handful of updates and amplifications to previously posted stories, including some naysaying to Lessig's idea of the spectrum as commons, more free books from Baen, and the European answer to GPS. Read on for the details.

Sir, you just need to trust us. geekee writes "An article on CNN claims that the proposed passenger-screening system for air travelers is much more innocuous than previously claimed. Now it is claimed that the Transportation Security Administration "will not view credit records, traffic violations or other personal data", according to Admiral James Loy. He also claims records of travel will not be maintained. "Airline reservation agents would provide a traveler's name, address, phone number, date of birth, and travel plans to the TSA, which would then check that information against a variety of commercial databases and an FBI watch list.", according to TSA spokeperson Heather Rosenker."

Thinking of the children means more than hiding their eyes. Jim Tyre writes: "You pointed out that my censorware.net piece ["CIPA Before the Supreme Court"] provided a nifty link to where the official supreme court oral argument transcript would be when available online. It's now available."

What's good for the mercantilists ... wait, no doesn't have the same ring. Lawrence Lessig says that the current radio spectrum is vastly underutilized, and that new technology can extract much more use from it, creating a true radio commons. Zo writes to point out that many Salon readers disagree: "Radio waves, bandwidth, the spectrum. . .Don't we know *anything* for sure?

Sir, these books smell fine ... what's the catch? silentbozo writes "Avid Slashdotters will remember the Baen Free Library, which puts up free web versions of Baen titles for ANYONE to download and read without having to mess around with encryption and DRM. They went a step further with this experiment last fall with the release of David Weber's War of Honor which had a bunch of novels in html, rtf, doc, palmdoc, and othe formats on CD (bound into the hardcover), which you could copy and give away to anyone. Well, they're at it again. In May, they'll have another CD for those of you who didn't get War of Honor, bound into John Ringo's Hell's Faire.

I got hooked reading John Ringo's books after browsing through my copy of the War of Honor CD... and it's a great way of catching up on the previous books in the series. Hell's Faire looks really good - I personally am looking forward to finding out what happens to the O'Neals as they fight the Posleen on Earth, and to the crew of Bun-Bun... Eat anti-matter Posleen-boy!"

As secure as ... well, you pick. Anthanos writes "pGina [http://pgina.xpasystems.com], a modular authentication framework for Windows, has come a long way since it was last noted on /. nearly a year ago. Since then a full-fledged LDAP plugin, PAM plugin, and chaining have all become part of the feature set. The kicker is the recently released Slashdot plugin, which allows authentication of Windows clients with... yup you guessed it, Slashdot Accounts! XPA Systems has even begun offering services revolving around this GPL product. Seems this may be the solution for people looking to merge authentication of Windows clients with MacOSX, Solaris, and other *nix boxen."

Let's see a handheld that uses both, please ... Mattias Östergren writes "Well aware of the risks with dependency of GPS the European Space Agency (ESA) have developed their own satellite navigation system, EGNOS. EGNOS is more accurate than GPS and the signal also tell you how much it could be off.

The first reference station have just been installed on the roof of the Land Survey in Gävle, Sweden. There is a Swedish press release about it."

    But seriously, all this background check BS is too much. Scan people and baggage. Lock the cockpit. Put an 'air cop' on board. What can you do? Not pay for movie headphones? (Credit be damnned, they make you pay in cash.)

    Background checks are unnessasary if the airport is secure in the first place.

    Ahh...I see. Its cheaper to run my SS/DL #s and invade my privacy than it is to change a door on an airplane. It must be, or airline would have done it a long time ago, because they care about people!^W airplanes.

      I think the theory goes that if someone has NO credit history (as opposed to a good or bad credit history), it's almost the same as having no past, and there's a higher chance that this person is using a false identity or an alias. Not that it would have helped with 9/11 because the hijackers travelled under their own names.

      The main reason people don't want guns on board planes is because having bullets flying around a pressurized cabin is a Known Bad Idea.

      This makes a certain amount of sense. While many people do end up in credit trouble through no fault of their own (catastrophic medical bills, job loss, etc), very often people who end up with poor credit do so because they are unable to properly manage their fiances. Perhaps this indicates they are also irresponsible in other areas of their life.


      It's an awfully big conceptual leap to suggest that people who get into debt and don't pay their bills are also likely to blow up airplanes, now isn't it? Or is "irresponsible" now synonymous with "terrorist"?

      If I was going to be a terrorist, I'd make sure I had spectacular credit and not do anything else to stand out from the crowd. Which, I suppose, means that I would rack up $10,000 in credit card bills. Oh well, so much for good credit.

    It's not like most people are letting their GPS device drive their vehicles or something.

    No, but they let Microsoft Streets do it for them. And it's really annoying when your car symbol jumps from one street to a parallel one.

    Anyway, check out Geocaching. It's awesome, but an accurate GPS helps out a lot. You go around finding boxes of prizes with only a GPS coordinate and a couple of clues. It's great for excercise, and it's fun! You hear me, geeks? FUN EXCERCISE!

    Yes, and if you want to redesign and replace every radio on the planet, using technology that is significantly more expensive, or doesn't even exist yet, be my guest. But you have to replace my TV with the $20,000 frequency hopping spread spectrum one.


    Also frequency hopping spread spectrum was designed to stop jamming since it's hard to broadcast across a very wide spectrum at high power. But give one of these transmitters to everyone in a metropolitan area and watch the mayhem insue. All cell networks use spread spectrum technology, and there are still subscriber limits.

    Please read the original article before you attack the character of people who put their real names in the reply. The pinhole camera thing came right out of the article, and highlighted the gross lack of technical knowledge of the author. College freshmen in physics and engineering know that radio waves interfere. It's the basis of quantum mechanics.


    The reply of Rauch was completely accurate. I'd like to see you send any signifcant power at modern radio or TV frequencies without a giant antenna. Mesh networking may be nice, but what happens when you're alone on a back road with your .1W transmitter that can send 100m? And, it still doesn't change the fact that all of the technologies that you mentioned are incompatible with existing technologies.


    Let the people who have EE and not CS degrees build the radios. Real life is not digital.

      So what you're saying is that the reason we can't move forward with radio technology is that people in the back woods will have no way to watch "Must Miss TV" (TM)?

      The sheer failure to grasp the concept is so amazing to me. Even the geeks don't get it.

      1) Open up some portion of the spectrum to unlicensed transmitters that are limited only by reasonable health concerns and basic mode of operations limits(ie. a few watts effective radiated power in the UHF band with "minimal required output power" type regulations).

      2) Allow modern economics, silicon engineering, and market demand factors to create useable mesh communications technologies, software defined radios, and software defined directional antennas.

      3) Sit back and reap the rewards of human ingenuity.

      Outside of the bandwidth assigned for unlicensed use you will not see interference due to the requirements that the devices not generate it.

      When we have enough experience and/or have created a system that truly offers reliable communications without the need for pre-assigned frequencies, then we can completely remove all frequency assignments and recover all the spectrum

      The RF engineers that jump on people's back about antenna sizes and power outputs and distortion and soforth are stuck in their tunnel vision that the future will look just like today.

      The futurists (Lessig, Reed, etc) publishing in a venue like Salon are not supposed to spell out the nitty gritty details of each step along the way, they are supposed to show us where we should be headed. I'm apalled that even the geeks can't take the ball and run with it.

      As for radio waves "interfering" they create a superposition, but that superposition is different at different locations. You are assuming that these radios will be stupid and have antennas at a single location. With several antennas seperated by even short distances combined with motion on th e part of some stations, and reflections, you can recover a tremendous amount of information from multiple sources.

      I have had an amateur radio license since 1989 and have my share of communications and radio frequency theory.

      WiFi is just the barest beginning and restricted to as you say a propagationally challenged spectrum.

      The point that you have missed is that the investment required takes economic incentive that doesn't exist in the current regulatory structure.

      You have missed the point that at first "we" want our own band with good propagation that won't interfere with current usage. One good example would be unused UHF television frequencies, most of these are unused in most areas, and it would be relatively simple to detect them and not interfere.

      The fancy multi-array antenna systems and mesh protocols will come a lot faster when it's possible to sell 160 million units a year unlicensed.

      Once they come, the current users will migrate away from their outdated broadcast technologies VOLUNTARILY because the new technologies will offer so much more... And if they don't so what...

    Limit wireless to short range, and put hubs everywhere. Problem solved (for urban areas; rural areas are an entirely different problem with different constraints).

    So you would have no free long range high power spectrum at all?

    There would be a few bands open for hobbyists, just like there are now. Want to build a 1 kW transmitter? Go ahead - just get your ham license first. Decide you're not going to play nicely in the community? Your license gets revoked.

    Without management, anything longer than short-range will cause too many people to step on each others' toes.

    The cost of all that badwith you want would be considerably less if more spectrum was given over to 802.11B type freedom. The equipment is cheap enough that people would build the infrastructure and run it as a free public service.

    The free public service would then start charging a modest fee to support its overhead, and then the core of people running it would slowly drift to the dark side as bureaucracy started fossilizing, and you'd end up with something indistinguishable from the bandwidth providers we currently have.

    Do you think that Cthulhu came to earth and decided to found UUNet to torment the mortals? Large-scale utility providers _naturally_ evolve to become this way!

    If you want cheaper bandwidth, start a letter-writing campaign to get better government regulation of the industry. It's a utility, just like phone and power and water and so forth. Manage it like one.
