that in fact runs untrusted code (say, third-party web applications) and places them in a Java sandbox, then they can use this exploit to leave the sandbox.
Only applets run in sandbox so there's nothing to leave. On the server side there are two choices:
- shared hosting (Tomcat): everyone uses the same VM just like with PHP so we are sparing memory, but increasing the security risk - virtual private server: everyone uses the their own VM and everyone is secure
So what makes Titan's atmosphere there? I know that there are hydrocarbon lakes on the surface of Titan, whether they count it in the atmosphere I don't know.
The point is, every little AJAX call has to be mapped to an URL. If your web framework comes with good AJAX support then it's manageable, but if they're using a homegrown framework with barebones Prototype and JQuery, then it can become painful.
You can say it's not the language, but for most users Javascript is a domain specific language.
Since the atmosphere of Mars is 95% CO2 and only 3% nitrogen, the fact that oxygen is a bit heavier than nitrogen doesn't really matter. There won't be much banding due to how close they are by weight.
But it's possible that solar wind isn't that important in the O2 issue. Still kicking off an exponential growth of biomass in a similar way as happened in Earth is pretty hard as there are no oceans. Most of oxygen production in Earth happens in oceans, and that's where the algas that transformed the atmospheres of Earth live. ( http://en.wikipedia.org/wiki/Cyanobacteria ) Most of our land plants actually need oxygen in the night when they use their carbohydrate supplies. Maybe some lichen could survie, but they grow very very slow.
So the terraforming process would last at least a few hundreds of years. But it seems the current scientific establishment wants to study Mars better before doing such radical changes.
Sending people there to make permanent colony seems rather unlikely and impractical in the next hundred years.
Also, oxygen molecules aren't really all that light, relatively speaking.
Compared to CO2 it's light.
CO2 44g / mol
O2 32g/mol
So most of the oxygen will be at the top of the atmosphere where you lose most of it due to solar wind.
Of course you have to properly solve a bunch of differential eqations to tell how nuch will you lose and what will be the equilibrium regarding O2 composition, but I wouldn't get my hopes high.
You'll never have 14 psi atmosphere on Mars as it has a 3rd of the gravitational pull at surface level as Earth. The other problem is the lack of magnetosphere. It also lacks the ionosphere which is held together in Earth by the magnetosphere.
Even the most hostile environments on earth usually have at least SOME oxygen, water, soil, air pressure
The moon even has most of those.
Mars has all of them.
Martian soil doesn't have humus, it's just sand and rocks. Mars isn't capable of retaining an earth-like atmpsphere because the solar wind will blow off the light oxygen molecules from the top of it. Agriculture has to be done in airtight pressurized rooms, water is only available in ice form and even that only at the poles.
So it has all of them, it just depends on your definition of soil, water. Oh, sorry you don't have oxygen either.

The Cube engine also has voxel based cooperative map editing, but out of the box it's just an FPS, it doesn't have the complexity of Minecraft.
Signed applets can access the hard drive. I don't know how they thought it's a good idea.
How secure is using Firefox 3.0?
Authors death + 70 years.
Suddenly the GPL license doesn't seem that bad after all.
There is an endless supply of "we want everything to be free and open!
No, we just intellectual works free that were financed by taxpayer money.

All the Java problems were with applets. Considering how many security problems were with Flash too, maybe the problem is with the browser APIs.
I don't know, the Penny Arcade guys disagree:

The is government is having problems with the insurgents because:
1, insurgents aren't afraid of suicide bombing
2, insurgents aren't afraid of killing the families of collaborators
Ouya has the strongest GPU that's on the tablet market, so your $80 Chinese tablet doesn't compete with it.
If you already have a decent PC the Steambox isn't targeted at you anyway. But I agree with the spreading too thin part.
The problem is, maximum 3 simultaneous key presses are registered.

Sorry, not carbohydrates, hydrocarbons.
Because it's covered in long chain carbohydrates which are much more dense than N2 or O2.

OK, I correct oxygen in colloquial usage means elemental oxygen or oxygen molecule. Stop playing semantics.
Oxygen means either the oxygen atom or the O2 molecule. Stop playing semantics.
