They are still using hardened electronics, but Jupiter's radiation belts are orders of magnitude more intense than Earth's radiation belts.

The main component to shield against in the Jovian environment are high energy electrons. It turns out that shields made out of higher charge elements are better at shielding electrons per mass. Aluminum is the defacto spacecraft material. You want something higher on the periodic chart than Al (for the best shielding to mass ratio), so they chose Titanium due to considerations like material availability and ease of manufacturing while still standing up to being launched into space.

Another possibility for high energy electron shielding is to take aluminum and place a higher charge metal (Tantalum is often used) layer right next to it. The Aluminum is the structural component, but the Tantalum is the shielding component.

Mod parent up.

My guess is this is exactly why they implemented this system. Students (and their parents) going to school administrators trying to get grades and degrees. Having taught a few classes and TA'd a bunch more, this is exactly why I always had a sign-in sheet.

I think the students in the article bring up some interesting points about the possibilities of abuse and tracking of students whereabouts.

Have not tried the latest, but IE7 works just fine.

>>>The latest version of Safari does not run on OS 10.5

No it doesn't. It probably would operate just fine if Apple gave you a PPC binary and let you install it, but Apple BLOCKS you from doing so. Apple controls Macs the same way they control iPhones, forcing expensive hardware upgrades on the users.

The drugs don't necessarily have to be illicit. For example, Dayquil/Nyquil tabs viewed over a cheap webcam would appear similar to Mike & Ikes.

While they aren't illegal, it's possible that they have older pills/generic pills that still allow them to Robotrip.

(This is, of course, all besides the fact that the school obviously did something illegal, and it doesn't really matter either way)

Like I said, it's nearly impossible to assimilate for the person who was raised in another country. Far too many things are ingrained at early age; the best we can do is consciously mimic the norms of the new society, but that kind of self-control tends to be blown away in stressful situations.

That is not to say that one doesn't acquire a lot of new habits. Not all things are that deeply ingrained, and even old dog can learn new tricks. The result is that most people who have lived for several decades in another country still don't look like natives there, but they also become different from the norm in their country of origin, sufficiently so that it is immediately evident from their behavior if they ever visit that country.

It's especially funny when it's a person from the "returnee" category who is disparaging the culture from which they've returned - there was one coworker of mine like that, who returned from the States after living there for 17 years. Every time he went on another rant about how stupid and soulless Americans are, speaking Russian with a definite American accent (occasionally slipping into English when he couldn't remember the Russian word for what he wanted to say), and accompanying it with distinctly American hand gestures, I couldn't help but chuckle.

The real criteria for assimilation is the second generation, children who were either born in the new country, or arrived there as kids. In families who want to assimilate, such children usually do so, and, short of appearance, you'd be hard pressed to tell any difference between them and the natives. This happens naturally even if their parents are mostly ambivalent about the whole thing.

In families that consciously resist integration, the parents actively preclude their children from assimilating by restricting their social circle to children of other similarly-minded immigrants, speaking to them only in their native language (and reprimanding them if they speak local language at home or in other social settings restricted to their cultural group), trying to limit their access to local mass media and products of local culture (TV shows, music, movies etc), and so on.

One can't deface graffiti anymore than one can trash garbage.

What a ridiculously ignorant statement.

A lot of graffiti has the primary purpose of marking gang territory. When those are defaced with other pieces of graffiti it is a sign of gang territorial disputes. Defacement is in fact the intention of the second artist.

Where you really show your ignorance, though, is in the implication that graffiti can't be art. Do you honestly believe that art needs to be officially sanctioned for it to have any validity?

you make some very good points. i was about to post a similar objection (i.e. that the android model is similar to shareware / freeware and the black hats can exploit that so it's "caveat emptor") but your post stopped me in my tracks. i still abhor the iphone marketing model. maybe something like a peer-review process could solve this...

Aussie Scientists Find Coconut-Carrying Octopus 205

An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"
