This app, giving people real time updates on their smart phones, is probably not the best thing we could have for public safety. More than a few knuckleheads would likely think they were doing the right thing by putting it on their phone, until they try to read it while driving and end up causing an accident by way of their distracted driving.

Good thing smart phones have speakers. Waze already make use of audio for turn alerts, they can do they same for Amber alerts.

"...solar-powered green chemistry using sequestered carbon dioxide."

Trees. Quit cutting them down. Plant more. Problem solved.

Actually, cutting down trees is a great way to optimize carbon storage, as long as new trees are planted to replace the ones cut down. It clears space for new trees, which grow faster and eat more carbon when they are young. The cut wood keeps the carbon locked up and is a useful building material. As long as the cut wood keeps the carbon in solid form it isn't going to affect the atmosphere.

I've actually seen plans where cut wood is dumped to the bottom of the ocean where it won't decay, then replanted in a constant cycle. That carbon would basically be locked up forever (at least until we start mining it at some point in the far future).

This is always been the solution, even after such massive failures as the Valve Anti-Cheat System on PCs. Have the game analyze the size, name, and even hash of all its files when it opens. If they're different than a preapproved list that's loaded into memory for milliseconds after being unencrypted with an enormous hard-wired password, refuse to open the game. That's moderately secure, assuming they can't get to the hard wired password.

How do you trust that the user hasn't modified "the game" to make it think the hashes always pass?

...That was not in the ore taken out of the ground in the first place?

At an elemental level? Probably not. But you better believe it at the molecular level. Aggressive acids and solvents that do not form naturally are common. You can read about some of it here. http://www.anzaplan.com/strate...

It's slower in languages with automatic memory management, or with a VM, which is no surprise.
It would be much faster than disk if you wrote the time critical parts in a language designed for, you know, speed...

In this case it's slower because they are not comparing apples to apples. For memory they repeatedly concatenate strings together, which reallocates the memory and copies the string every time. For the disk they allocate the whole file at once and then just stream the data. It would have been a much better test if they had allocated a memory buffer for the string and streamed the data in to it the same way as a the disk.

Please, world population has nothing to do with the people currently starving. That's all down to local politics. Warlords and 3rd world governments seize or otherwise don't allow food to get where it needs to go. We could easily support a population at least 3 times higher than we have now if people would stop being dicks.
