On Earth: The density of air at sea level is about 1.2 kg/m3 Divide by 100 (pressure difference) times 3 (lower gravity) gives 0.03 kg/m^3. Bump it up to 0.1 kg/m^3 because its CO2 (higher density) and lower temperature. So you have 12 times less lifting capability compared to Earth but one third the gravity so you will need four times the volume of the balloon for the same lifting capacity.
I suppose its doable but remember the weather balloon which got away from its handlers in Australia some time back. If this one has to launch from the ground without people holding the wires then there are going to be some problems.
ARES will be pre-programmed to land on Mars. Once ARES has landed,
TFA doesn't say how they will get the vehicle on the ground but I am willing to bet it won't glide to an unpowered landing. More likely it will carry a small airbag or powered descent lander but I doubt it will be able to carry enough payload for a lander which can last a long time on the surface.
It could be a commercial thing. Japan exports a lot of electronics and most it is aimed at westerners. It wouldn't pay for the robot to be designed to look Asian, even though its just a skin they stick on to the outside.
I had a long read through the language spec and Go seems immature to me. One example is the way it enforces K&R style braces. The authors claim that this is done to simplify the parser. But honestly, what do you compromise by having a more flexible parser?
If you look at the openmoko (I own two) the answer is yes. You need it to suspend to save power and wake up fast enough to be of use. While in suspend it needs to service things like the network interfaces without needing a full restart when it wakes up. It needs to cope with lots of permutations which developers won't take it through. For example if plug the moko into my car power charger and go for a long drive it will come on and off charge every time I switch off the engine, some times when it is in suspend, some times not. Often the daemons which handle power management hit an unhandled state and crash, then power management stops working.
In power and comms these things are bleeding edge, and quite expensive to get working properly.
The Libs were in the news promising to look again at the Doncaster line and a refuse to believe they will build it. They will probably put another two lanes on the Eastern freeway and say its fixed. I am not claiming that Labor are any better BTW.
I think the attacker is a different person here. If you want your data to be secure you will use a secure system. If you want to defraud the Government then you may create a deliberately insecure system.
Everything the candidates say at this point is pandering. Doctors represent a block of typically right wing (Liberal party) voters and donors. Appealing to doctors can potentially have a direct affect on Liberal votes.
But I don't think it will make much of a difference. The campaign is on autopilot. Candidates are promising the exact opposite of their historical positions. In my experience the bureaucracy runs the state anyway so it doesn't really matter who wins.
I'm a Victorian but I have only been skimming the news. Basically our politicians are saying whatever they think might help them get [re]elected even if it sounds totally stupid. For example the Liberal party is proposing to build train lines in metropolitan Melbourne. In my 45 years of living in this city the only thing the Liberals have done with trains is close them down (and then Labor reopen them), so a Liberal politician who says he is going to build a train line is clearly talking crap.
The iPads will be forgotten on the Sunday morning after the Saturday election.
And since the ID card and desktop software know nothing about the operating system they run on there is no way to be sure they will behave as expected.

Whats your point?

You can test at high altitude on Earth, possibly by deploying the aircraft from a balloon.

Makes me wonder why I have to pay 10 bucks a month extra for a static IP.
Do "Virtual Girlfriend" simulators have G-Spots?

Hang on while I ask a New Zealander.
I predict at least 50 more.
So you plan to change the number of bad jokes by reading the thread?
There is a difference between tolerating faults and ignoring them.
Well... the UK Government was treating him pretty badly at the time.

If a bunch of special ops guys with guns want to steal power from a line before my power meter I think I will let them get on with it.

The olderer I get the more cynical I get.
An approximation of one anyway.

They are not actually going to buy anything. This is an election promise.

I don't think the men have got much do to with it.

Skylon uses an air-breathing rocket engine.
And with current technology its easier to carry a tank of LOX.
