Hey VHF and UHF are cool. Not saying anything bad, about them, just a matter of range. In fact, you could make long-distance contacts with the right antennas by using amateur satellites, or with a lot of power, the Moon.
And then there's these crazy guys. http://www.df5ai.net/Material/...
I'd hate to have to rely on that for comms, but it's remotely possible.
My first cross-pond QSO was via Packet on 2M connecting up to an HF gateway to London in '92. Back then it was pretty impressive, I didn't get my first real email address til 1994.
The great thing about our hobby is that there are so many different ways to be a ham, there's something for everybody!
Surprising that so few hams in Nepal are setup for HF operations. I wonder how many HF ham stations there are in the U.S. One can't tell by license class. I know that in a real emergency my QRP FT-817 is not going to be the most reliable but until I can fork out for some bigger solar panels and batteries to run an amp, 5 Watts is going to be what I've got. With morse code that's enough to work the world, sometimes. Beats the hell out a walkie talkie.
Recruiters are idiots. You're going to have to do some coding for free to prove your mettle. Open source projects are always looking for coders if you can't think of anything that you'd like to write. Something like http://code.google.com/p/kerne...
Funding for space goes up in Republican administrations because space exploration has traditionally been an outgrowth of the armaments industry. Put a capsule on a Titan II and it's a rocket. Put a warhead or several on it and it's an ICBM. Building and testing peaceful rockets helps national defense.
WTF are private organizations allowed to issue identities for? Government IDs may be a hassle, but they're the ones with the vested interest in keeping track of people. We don't permit Walmart to issue driver's licenses or passports. We already have a mess with the private CAs on the Internet. Do it once, do it right and keep a monopoly on it. IDs and currency are Government's job! If the Treasury had issued decent ecash, Bitcoin wouldn't have a market and Credit Card Companies wouldn't be adding their 2.9% inflation to every purchase. If the Gov't were to do this right, with closed-loop verification necessary for anybody to do anything with your Identity, and if it were secure it would be a great boon. No more having to notify 42 entities of your change-of-address. Change it once at the Identity agency, and it's changed everywhere. I really doubt they'll manage to get it right though.
No, I don't work for the Government. I'm just a guy who hates constantly giving and updating contact info.
Summary says "impossible to" . Article says Next to Impossible to. Let's have the boys in the ISS take a few pics out the window. It's not as convenient and the passes are much less frequent, but hey, it's something. Also GOES 14 is coming on-line. Now if that fails, we really will be limited to ISS observation.
This is true, but launching large items is difficult, volume-wise. I know there are ideas for for inflatable mirrors and spray-on aluminum, but so far there has been virtually no manufacturing in space, aside from tiny crystals and SuitSat. I think the L2, or at least BEO position of the mirror is advantageous. We don't want to clutter LEO even more with debris, and there's no point in bringing an asteroid all the way back to Earth to melt with a solar furnace, especially if you're going to be using the products further out. We're already up the Well with Herschel, at substantial sunk cost.
If it were easy, anybody could do it, and it'd already be underway. Good summary of the issues. I think robotic dexterity is probably sufficient for the mission, see http://en.wikipedia.org/wiki/Shadow_Hand and Robonaut2 http://www.nasa.gov/mission_pages/station/main/robonaut.html
The real challenge is software, the light lag at L2 would make realtime teleoperation infeasible. Darpa has teams working on recovery robots for terrestrial uses.
I'm all for launching big mirrors also, but this one has already paid the energy cost of getting out of LEO. I think there are substantial savings here, especially if we use existing assets and pair the tug + robot at the ISS.
The big issue that I can see is political. The JWST is already slated to be positioned at L2 and they won't want industrial debris floating around. May have to tug the Herschel out of range before recovering the good bits. An ion drive can do that, slowly.
WIki says that there are no plans for the Robonaut 2 prototype already on ISS to be returned to Earth. I smell stone soup space mission. Thanks taxpayers!
SpaceX should go after it and salvage it robotically for use as a solar thermal concentrator. 3.5M mirrors that are already in space don't exactly grow on trees. A simple high-efficiency Ion engine (Dawn-class)and a robonaut should be able to handle the job. They can then lease the asset to Planetary Resources or whoever wants to do industrial experiments.
Doesn't have to be quick. Cheap and slow is the way to go here.
Heh, lucky you. I bought a c64 a couple years earlier and only the third one lasted more than a couple of weeks. The other 2 had to be returned for a blown power supply and a defective keyboard.
Now admittedly that last one lasted at least 12 years or so. For all I know it may still work, but I had to get rid of it.
Your staff members should be the ones crawling under the desk. You're the department head for God's sake. Act too busy or something. Rank hath its privileges. Personally, as a self-employed consultant, I wear a button-down with the collar open and black Dickies work pants (non-cargo) as ordinary dress pants rip too easily and get snagged on stuff while crawling under desks.
Read the question. I wasn't questioning who they were, I was questioning their expertise. In my book, people who do not have a solution for a problem can hardly be considered experts in the problem. Any idiot can say "abandon in place." It takes no special knowledge.
Apple makes its profits primarily on hardware sales. And it's mostly standard Intel hardware. Why would they care if you decided to put Debian on it? How could they stop you? Of course, that raises the question of why you are buying such expensive hardware just to run Debian since you don't like Apple's Software, but some people are willing to pay extra for industrial design.
Samba has switched to GPL v3. Past editions used GPL v2. Thus large chunks of the code are already multilicensed. You are correct that the GPLv2 does not require all publications to accept later licenses, only that that is an option if so chosen by the authors. The Samba authors have chosen to use at least one later version of the license. This is an interesting question actually,if the original authors have chosen to move up to a new version of the license and somebody makes modifications to an earlier revision under the earlier version of the license, are the modifications barred from being incorporated into a new version controlled by the original authors if the original license did not specify that later licenses may be used?
Hmm, how so? GPLv2 says that it can be used under that license or any later version. If the community wants Apple's patches and Apple cares to give them back, then they can. They will probably be advised by their lawyers not to though for fear of confusion. Look, it's in a GPLv2 and a GPLv3 project! Suddenly version control timestamps become very important.
They really ought to include a text expansion feature in all IM and SMS programs. Then when the kid types gr8, it will appear as great in the actual message and there will be visual reinforcement of the correct spelling. It will also serve to reduce annoyance to people who hate txt speak. If the 140 char limitation is important in the application, then the messages can be transmitted as-is in txt-speak and translated automatically on the other side. Think of it as a primitive form of message compression.

4 cm across? I say use birdshot on the swarms. Just watch your backdrop.

Hmm, just reread the article. The earliest instance is 'impossible' the next mention is "next to impossible." Poor editing, and inaccurate to boot.

The guy was talented. The Stainless Steel Rat series was quite funny.

I'm marrying the sexy librarian I met on OkCupid next May. They're out there guys, just rarer than diamonds.

What makes them experts? How much space junk have they cleaned up? Which orbital paths have they cleared?

Seems like an overreaction. Just fork the V2 version. Or maybe that's what they're doing.
Cox, the Computer Scientist, should sue Lacy for harming his reputation and making unfounded allegations.
