  1. Re:Jamming. on X-45 Makes Debut Flight · · Score: 1

    Only your transmitters need to be cheap. If you can build a box and run it out to a few hundred antennas, the home-on-jam devices keep knocking out your antennas. At $500,000 each for an anti-jammer missile and $500 for an antenna and a bit of coax the numbers aren't good. Also keep in mind that some of the cheap spark gap transmitters work great for messing up some types of transmissions and Telsa had lots of cheap devices that will mess with a wide range of spectrum. The reason that the modern military jamers are so expensive is they only want to jam their enemys signals not their own. If your not using radio to such a high level you can just bust the whole spectrum.

    That assumes they can. It took years to get cruise missles to work correctly and nearly a decade to retrofit GPS into them.

    The way most countries will look at these is you have to take out the command and control system and to do that you nuke it or the communication sats. Waht this has done is just moved up the bar on the space weapons race.

  4. Re:Scarcity? on Unlimited Airwaves · · Score: 1

    Thats wat a GPS reciever does until it knows where it is and what sats it can find. It searches all the posabilities until it locks on to one sats signal and then starts downloading a list of what stats are up and where they are. Once it has that, it uses its last known position and tries to lock onto other stats. If that position is good, it can do it quickly otherwise it could take a good reciver nearly 15 minutes. The data messages from GPS sats are at something like 50 baud in the 1.2Ghz range but the signals are below the noise floor by the time they get to the front end of the reciver.

    The optical transmitters are teh easy part. That
    bit has been solved to the rate of about 3.6petabites/second. The problem is the recivers can't do that (not to mention that 10baseT device you want to plug in).

    Now that people are looking at optical as RF and not as visable light, some of the sensors technology that is in R&D labs right now is good for 25km in rain and fog in the gigabit range. Its still point to point but the research is going places and I expect the line of site radio links are going to be gone in 15 to 20 years.

  8. Re:It's a matter of finding things again... on Unlimited Airwaves · · Score: 1

    Has this guy seen how modern radios work? You start out with a binary signal. Then you find out where you modify your carrier on of say 64 different ways based on the next 4 bit patterns. (some of them aren't used as type of sanity check)
    Modern radios will do sevral bits per Hz while his charts are showing about 1 bit per 10Hz. Now back to thouse 64 different patterns when you only need 16. What happens when another radio steps on your signal? You get one of thouse other bits and your reciever decides not to accept that bit and hope your forward error correction copes with it. Some radios work by taking the signals and spliting them into 8 groups, inverting some of them ina pseudo random way and transmitting them either serialy or on silghtly different frequencies. The reciever at the other end can take all them at once do a bit of voting and then check aginst the ECC code to help get rid of th noise.

    This all works well until you have too many transmitters in one are all talking at once. Think about hearing converstations in a loud bar. Its the smae problem but you tend to only hear the people near you or the very loud ones. You can't hold a conversioation at a moderate volume with someone far away. Human speech has much better noise imunity than most radio signals.

  16. two comments on r* Programs Being Removed from OpenBSD -current · · Score: 2

    Pulling Perl from the base package will limit the flexibility for many of the set up scripts but I can see where the size of Perl has gotten way out of hand. Maybe they should look at mini-perl (the one perl uses to configure its self) might be worth considering.

    The R commands need to go away but I'm wondering if the best option is to fix them properly. The idea here is to put together a library (maybe a fork of getops) so that you can take most standard programs that use stdio and make r versions of them by linking to the proper library. This way things like rmt (remote mag tape) and its friends restore and dump would all still work in a modern enviroment. There is no current version of dump or restore that works the way old rmt versions do and most of us still like to do backups from time to time.

They build a small file and then xmodem it off to some connecion on the old CIS network so its not big on security but at least it works unlike my banks payment system (which uses some new shiny interface to the same backend and might just use the same CIS interface)

    Years ago it required quite a few people and lots of money to put together a record. Now anyone can put together something that has a good sound if they have talent.

    I don't think the RIAA represents anywhere close to 90% of the artists out there. For example there are about 3000 bands in Melbourne Austraila that can put together an album per year (according to entries from a local radio station). If the US has as many bands/person there should be nearly 300,000 bands that produce at least one album per year. Consider that people like Bing Crosby made nearly 33 songs per year and popular bands tend to record 8 to 16 songs a year. So how do I get access to thouse 2.5 million songs that were recorded last year? Current album sales in the US are around 3/4 billion units per year but most of thouse are the top 40 albums.
