Convenience is a subjective quantity. It is much handier to just leave your keys in your ignition switch than to have to keep track of them or fish around in your pockets every time you want to do something as routine as open your car door or start the engine. (Don't we all just love car-computer analogies?)

Full disclosure has been shown to be the most reliable way to get companies to fix security problems in their software..

Bugs will be found and exploited privately whether public disclosure takes place or not. There is a thriving market for zero-day exploits--exploits that are then used either by governments of criminal organizations to render computing systems to be less reliable and/or secure than their owners would expect them to be.

Some convenience will always have to be sacrificed in the interest of security, whether the system in question is a computer, a car, or a house. The only way to absolutely maximize convenience is to absolutely sacrifice security. (and privacy)

" Even if signals in the chip were moving at the speed of light, a chip running above 5GHz wouldn't be able to transmit information from one side of the chip to the other."

Eh?

At 300 Megameters per second, the signal would travel 6cm during one clock cycle. Just how large of a "chip" are we talking about, and how much clock skew can we design into our processor?

I call bullshit on the above statement.

When dealing with 'users' of the caliber that you describe, it really isn't possible to securely exchange data. Unfortunately, most 'users' can't be trusted not to have the file scraped off of their own box once they've received it. Without a minimal amount of computer knowledge and skills (which appears to be beyond the capabilities of most users), it just isn't possible to guarantee any security at all.

It turns out that the Department of Defense Lenovo computers are much more reliable than the average computers. In fact, the ThinkPad notebooks have failure rates of up to 16% lower than the normal average. The ThinkCentre desktops are even better at 28% lower!

+ - Satellite Internet connections for South America (specifically Peru). Advice? 6

Submitted by EdIII
EdIII (1114411) writes "I've been looking on the Internet for a decent contention service (4:1,10:1) in South America and I am not finding much. I have also heard that some frequency bands are a lot better at cutting through cloud cover. This is for a fairly remote ground station with reliable power generation, but also routinely cloudy. I would need at least 3/1Mbps with hopefully decent latency. What's your advice Slashdotters? Yes, I know that some of the solutions can cost 20K for deployment and 2-10K per month for service. Not looking NASA results with Home Depot parts on the budget of a 7/11 chiclet. Feel free to to tell me about a good commercial service. There is another ground station that might be deployed in north east Alaska. Thanks"

+ - Fuel cell-powered data centres could cut costs, carbon->

Submitted by angry tapir
angry tapir (1463043) writes "A group of Microsoft researchers believe that using fuel cells to power data centres could potentially result in an "over 20% reduction in costs using conservative projections", cutting infrastructure and power input costs. In addition, using fuel cells would likely result in a smaller carbon footprint for data centres. The researchers looked at the potential of using fuel cells at the rack level to power servers in data centres — although they note there is a long way to go before this could become a reality (not least of the small worldwide production level of fuel cells)."

+ - Linux 3.12 Release, Linux 4.0 Kernel With Only Bug-Fixes Proposed->

Submitted by Anonymous Coward
An anonymous reader writes "Linus Torvalds announced the Linux 3.12 kernel release with a large number of improvements through many subsystems including new EXT4 file-system features, AMD Berlin APU support, a major CPUfreq governor improvement yielding impressive performance boosts for certain hardware/workloads, new drivers, and continued bug-fixing. Linus also took the opportunity to share possible plans for Linux 4.0. He's thinking of tagging Linux 4.0 following the Linux 3.19 release in about one year and is also considering the idea of Linux 4.0 being a release cycle with nothing but bug-fixes. Does Linux really need an entire two-month release cycle with nothing but bug-fixing? It's still to be decided by the kernel developers."

MojoKid (1002251) writes "Microsoft has several valid reasons why you should upgrade to Windows 8.1, which is free if you already own Windows 8. However, there's a known issue that might give some gamers pause before clicking through in the Windows Store. There have been complaints of mouse problems after applying the Windows 8.1 update, most of which have been related to lag in video games, though Microsoft confirmed there are other potential quirks. Acknowledging the problem, Microsoft says it's also actively investigating the issues and working on a patch."
