Meant to have a "large amounts" in there. I thought it was part of the rules to track money laundering, just as any transfer over $10k (or is it $5k?) must be reported. Banks definitely scan large deposits, but I can't find a link to a legal requirement for the serial numbers (they scan for counterfeits as a matter of course). Bill serial number scanners are a real product, but they seem to be marketed to police evidence rooms, not to banks, so I could just be confused on this one.

Bicycles honestly do belong on the road. Where else are you going to put them, on the sidewalk?

They belong under my wheels. Keep your toys off my infrastructure. You will join the other pit slaves on Paving Day, doomed to a life of cleaning public toilets while I cruise the paved world in my hypersonic atomic car, under the light of the chromed moon.

A government could of course shut off BitCoin, torrent, email, or anything else on servers connected to the internet. The problem with BitCoin (unlike email) is it doesn't realty work on ad-hoc networks. Maybe there's no central authority, but a central network is required, so that transactions from anywhere can be processed by every processor (miner).

BitCoin is quite vulnerable to a powerful government agreement deciding to purge it from the internet. That seems unlikely though, as I think the big players will be content to track it.

Banks are already required to scan and report the serial numbers of all banknotes for deposits/withdrawals. Heck, the last time I got cash directly from a teller, it came not from the teller's drawer but from a dispenser that probably had a scanner built in.

But if I get cash from Alice and give it to Bob, no banks involved, it's anonymous. Unlike Bitcoin.

UN Study Shows Record-High Increases For Atmospheric CO2 In 2013 427

Figures released Tuesday by a United Nations advisory body reveal that 2013 saw new recorded highs for both carbon dioxide and methane, as well as the largest year-over-year rise in carbon dioxide since 1984, reflecting continuing worldwide emissions from human sources but also the possibility that natural sinks (oceans and vegetation) are near their capacity for absorbing the excess. From the Washington Post's account: The latest figures from the World Meteorological Organization’s monitoring network are considered particularly significant because they reflect not only the amount of carbon pumped into the air by humans, but also the complex interaction between man-made gases and the natural world. Historically, about half of the pollution from human sources has been absorbed by the oceans and by terrestrial plants, preventing temperatures from rising as quickly as they otherwise would, scientists say. “If the oceans and the biosphere cannot absorb as much carbon, the effect on the atmosphere could be much worse,” said Oksana Tarasova, a scientist and chief of the WMO’s Global Atmospheric Watch program, which collects data from 125 monitoring stations worldwide. The monitoring network is regarded as the most reliable window on the health of Earth’s atmosphere, drawing on air samples collected near the poles, over the oceans, and in other locations far from cities and other major sources of pollution. The new figures for carbon dioxide were particularly surprising, showing the biggest year-over-year increase since detailed records were first compiled in the 1980s, Tarasova said in an interview. The jump of nearly three parts per million over 2012 levels was twice as large as the average increase in carbon levels in recent decades, she said.

If I'm running your OS in a hyper-visor, I can pause the VM and dump the memory. Then I've got your key because the OS loads the key into memory.

Your provider can see your data in the clear. End of Story. Physical hardware is the be's all end's all.

Some things are true across all the big players (I don't know about the government-audited services; I can only imaging there's even more tracking).

If you're running the service, you don't have access to the datacenters, and likely don't even have access to the location of the data centers (the big players all keep exact datacenter locations somewhat secret - they have addresses, but the addresses don't mean much). If you work at the data center, you don't know what any given server is doing. So you don't really have physical access to the hardware in a useful way.

Further, everything is logged and audited like crazy - not so much for stuff like PCI compliance, but for troubleshooting. If a server falls in the woods, a whole team will hear. I'm sure everyone has tools to let you remote into any given hypervisor, but I'd be quite surprised if you could do so without a heck of an auditing trail.

It's not quite there for banking, but for most normal business, chances are there's more safety against a bad employee of MS Google, or Amazon than there is protecting you from your own IT staff locally.

Comment Re:NASA bureaucracy at it again (Score 1) 51

As with anything on Slashdot that starts with armchair experts asking "didn't they think of X?", well, of course they thought of X. Weight of the probe is the primary cost of the mission - nothing's heavier than in must be.

These wheels were tested extensively, and work just fine in normal rocky soil - they're more robust than car tires. But glue a spike to the ground pointing up and it goes right through the wheel. There was no reason to expect Martian Caltrops, but that's what was found: sharp spikes of rock that aren't merely stuck in the soil, but seemingly extruded from the bedrock (like you can get with a'a lava).

For those who don't follow this stuff: the rover has tin-foil wheels, and they're getting chewed up fast (many holes and tears in them already). The problem is sharp rocks that are embedded firmly in the ground, or perhaps part of the bedrock like a'a lava - a geological feature that wasn't expected or designed for. The rover can handle sharp rocks in soil just fine, but now they're going really slowly trying to find a better path.
