  1. *cough*
  2. Oh, you want just the permissions, in which case I'm guessing you're going to have to write a small shell script.
  3. tar lets you maintain permission settings. Read the manual.
  4. Spectrum analyzer, not a frequency counter.
  5. Amateur radio bands are not simply open. You need to get a ham license, and there are rules, such as no music what so ever, band planning, and various conduct codes. FRS and CB have various rules too. Unlicensed FM broadcasts simply have too little power to make anything practical. Furthermore, putting any effort into it simply to play music seems like a waste.
  6. Legally, it would have to be extremely low powered. The power limit for unlicensed FM transmissions is a signal strength of 250 microvolts per meter, measured 3 meters from the transmitting antenna. At this power level, stereo reception is only possible within 100 feet. I remember some discussions about setting up something like a distributed radio station using a bunch of these types of broadcasts. If you wanted to go pirate, you're going to get busted eventually, which will result in hefty fines. Probably not worth the trouble. There was a panel at H2K2 about pirate radio (Audio). Oh, and if you do go pirate, call it KRAP-FM
  7. I have a weird obsession with shortwave numbers stations.
  8. But think of the nostalgia! When was the last time you heard modem noise?
  9. You've clearly never used C, or any language for that matter, to write a multi-threaded program that can handle load. Furthermore, one moment you say that Ruby's threading is a good thing, now you're trying to ignore the valid criticism. Which is: Are you proud of it's threading or not? My other two points are also valid. You made up that Perl statistic, and you clearly don't know what dynamic typing is if you think Python's forced indentation has anything to do with it. And finally, one moment you say "right tool for the right job" and the next you denounce languages because they're unknown. You've done nothing but contradict yourself and back peddle. Take a position and defend it.
  10. Concurrency is the future. Explore languages that have strong built-in support for concurrency. I'd recommend Erlang or Limbo. Erlang is the more practical language, but Limbo has its up-sides, namely Inferno, the virtual machine it uses.
  11. 92% of statistics are made up. 43% of people know that. Ruby's concurrency support is pathetic compared to other languages (Erlang, Limbo, Mozart/Oz, Alice, etc). The implementation choices are inherently flawed for dealing with large-scale concurrent programs. They're really not something to brag about. What does Python's forced indentation have to do with dynamic typing? It's a choice the designers made to try to enforce readable programs, one that most good programmers would enforce naturally.
  12. This is true, and I agree, MD5 should not be used in future projects, but I am tired of people acting like MD5 is now the rough equivalent of rot13 encryption. It is still a strong hashing tool if what your trying to protect isn't of the greatest importance. It also works well to CHECKSUM executables, where the odds of having a working Trojan or corrupted file having a collision are near to nil. *cough* I'm done talking about MD5 stuff -- back to our regularly scheduled topic.
  13. Although it's completely off-topic (proxies->md5, who knows how), MD5 should be considered busted. Check out the hashclash project for more details. No, you cannot crack an MD5 is uber-small time now, or reverse one, or anything like that. But it's flaws have been shown and are exploitable. It should be considered busted and not used in the future -- that's all I'm saying.
  14. As you add amplifiers to a cable, you lose signal quality. Therefore, the longer it gets, the slower the connection. If it's long enough, it's useless. Satellite has a long delay making it useless for backbone Internet traffic. Just look at the delay on a satellite TV hookup when they do an interview on a talk show. Fiber optics can have multi-terabit per second speeds. Combine that with running multiple connections, and you can handle almost anything. More info
  15. Optical Amplifiers. Southern California to northern California is nothing. Traceroute a European website and watch it jump across the deep blue sea.
