each tonne of CO2 implying the consumption of about 360 kilograms of oxygen (mostly coal consumption)
Each tonne of CO2 implies the consumption of 720 kg (0.72 tonnes) of oxygen, as there are two oxygen atoms in each molecule of CO2. Burning hydrocarbon fuels however removes even more oxygen than just that which is bound as CO2, since the hydrogen is also burned to H2O. Acyclic (chain) hydrocarbons as commonly found in fuel oils have approximately twice as many hydrogen atoms as carbon atoms, so each tonne of CO2 produced from burning diesel or other fuel oils (or natural gas) will consume 720 kg of oxygen for itself and another 360 kg of oxygen for the H20.
Meanwhile the Fairphone is a modular android phone, with end user replaceable parts that exists today.
None of this would have seemed magical to someone from the 1980s, as the precursers to all of it already existed and it was a case of developing the technology further, which given the rate of technological progress at the time seemed very likely. And science-fiction authors and moviemakers had been describing many of those things for at least two decades (Star Trek and 2001 are but examples).
The standard Steam refund policy applies to No Man's Sky. There are no special exemptions available. Click here for more detail on the Steam refund policy.
It's a bad sign when they have to remind you of their refund policy. I bet their support system is completely overloaded with complaints, asking for a refund.
As far as I can see from available information, the HoloLens has a focal distance somewhere around 2 meters away from your face.
Whereas in a "true" hologram, you capture the interference patterns of all light rays that pass through the volume of your photo sensitive film. Shining a laser through that film will recreate light rays with the same direction and intensity. As if you were looking through a window at the original scene.
KDE used graphics features that should have worked but didn't everywhere. It was single handedly responsible for pulling up graphical support on Linux desktops and resulted in Compiz and all the other comparable Windows and OS X stuff that came about. Without KDE 4 Linux desktops would still have looked like bloody Motif.
Compiz predates KDE4 by about 2 years.
exploiting software doesn't even rank among the top five plays in the attacker's playbook
Only *because* you've been "Playing whack-a-mole with software vulnerabilities". If you stop applying patches, using exploits would be more productive.
Activities and Views are fine, I guess. But forcing serialisation of state between screen rotations sucks. A good presenter model with lifecycle management, baked in from the start, would have been nice.
IMHO Google made things worse with Fragments. If you follow the code examples, you end up repeating yourself with lots of nearly empty Activities, just to host your fragments on a phone instead of a tablet.
In previous years, they had been quite careful to inform people to pre-fill their form before census night, and submit after. This year they were expecting only a minor increase in peak traffic.
Then they go and blast the message, "Fill in your form online, ontime or face massive fines", all over the media.
So what did we all do? When the majority of 9-5 workers got home, we all tried to login and submit at about the same time.
Sure they screwed up their network config, but it was a combination of poor planning and poor communication that triggered the whole mess.
Injuries yes, but nothing comparable to that from a full-sized prop or helicopter rotor.
I wasn't thinking so much of laws as the situational awareness needed to operate a much larger machine in a confined and uncontrolled space around people.
