Comment Re:What troubles me most (Score 1) 810

Maybe I can interest you in this very illuminating talk by Seth Schoen and Jacob Appelbaum. Jacob is the Tor spokesman and the only American working for wikileaks. Seth is on the HTTPS Everywhere project. http://thenexthope.org/talks-list/

The Tor project has seen an increased focus on Internet censorship as many more users adopted Tor to get around blocking. In the past year, Tor was a popular means of bypassing censorship in Iran, China, and around the world. Firewall operators have been noticing. Tor has also had to contend with new organized efforts to block access to the network, and has rolled out the “bridges” blocking-resistance system in earnest. Alongside the perpetual need to get more Tor nodes, it’s become important to get users to run bridges – and to experiment with ways of communicating bridge addresses to users affected by censorship. The current censorship landscape will be explored, along with the bridge mechanism and efforts to recruit more bridges. There will also be an update on how Tor developers are responding to the growing pains and dealing with scaling challenges associated with Tor’s popularity. You’ll also hear about the challenge of counting the number of users on an anonymity network, and how client software can force the use of encryption to protect users from some attacks after their traffic leaves the Tor network.

Had the present leaks occurred when we were still considering war with Iraq, do you think we'd be in the mess we are today? As I recall, the media published only what the government wanted us to hear, that the rest of the world supported us. Because the public bought it, the congressmen bought it, and the debate was over before it began. Would you rather us wait until the next war starts?

You're saying that the reason that you're not doing the job that I'm paying you to do is that you don't have a job to do? Is that what you're saying? What are you trying to convince me of, exactly? That you're as useless as an asshole right here? Well guess what, Buddy. I think, you just fucking convinced me! -Larry Gomez

Asteroids are not that radioactive, but there's a lot of radiation due to cosmic rays. high energy particles from the solar wind are also extremely dangerous, not to mention those coming from transient events like coronal mass ejections. If you don't have a magnetic field to deflect particles or a thick atmosphere to absorb them, then you're at risk. Even shielding of a spacecraft (or aircraft) can make matters worse by causing secondary collisions that interact more strongly with human tissue than the incoming high energy particles. I have heard that if you bury yourself with a few inches of dirt inside an asteroid or the lunar regolith, then you should be fine. It's the commute that kills.

The moonwalkers knew it was prudent to wait for the moon to be full before making the trip, so that they would be shielded by the earth's magnetotail. However, this was before space physics models existed - they didn't know that they could end up effectively sitting in the solar wind if the interplanetary magnetic field shifted southward, and that's something that occurs rather frequently even during low solar activity. So they apparently drew their cards right. However, if we're planning to leave the earth's magnetosphere entirely then we'll really have to come up with something fancy.

The radiation problem is a big one, and I think the public doesn't yet realize how big of a problem it is. I mean, flight attendants and pilots are exposed to about as much or more than someone working in a nuclear power plant, so shouldn't they be wearing radiation badges? http://iopscience.iop.org/0952-4746/21/1/003 Now fast forward 50 yrs, with asteroid mining profits starting to take off. Will similar health risks get swept under the rug?

I mean, you could blindly aim a spaceship through the belt, and as long as it can take collisions with pebble size objects, it'll almost certainly make it through unscathed.

Don't forget, we need a pretty good estimate of the velocity distribution out there before setting up shop. A pebble-sized object moving at 500 km/s can really ruin your day.

Comment Re:And So Offered Another Inaccuracy (Score 1) 495

The article's summary is a bit narrow-minded. My suspension of disbelief for the exploding ring has less to do with the distribution of mass (almost spherically symmetric) and more to do with the distribution of energy. The fact that a lot of astrophysical objects have a clear axis of symmetry should hint that a man-made object capable of destroying a planet could also have an axis of symmetry.

KTRU is turning into another causality of the HD radio scam. There's a nice article http://keeppublicradiopublic.com/2010/08/21/beating-the-borg/ that summarizes the problem:

... if the future of public radio is to serve both the fine arts and news/talk audience full time and the public is slow to adopt HD radio, then you have to acquire more than one station and serve it up in glorious analog. Which is exactly what Colorado Public Radio, Vermont Public Radio, and many others have been doing for several years.
