  1. Not plagarism on Oracle Refuses To Accept Android's 'Fair Use' Verdict, Files Appeal (wsj.com) · · Score: 5, Insightful

    Oracle's brief also argues that "When a plagiarist takes the most recognizable portions of a novel and adapts them into a film, the plagiarist commits the 'classic' unfair use."

    All that goes out the window when the novel's author openly tells everyone to use the novel without charge, which they do. Then the author dies and the person who buys the rights to the author's estate unilaterally decides it can undo what the author did in the past and tries to charge back-royalties for past use.

    A more fitting description here would be "bait and switch."

    transmitting digital data at a rate of 105 Gbps (gigabits per second) over a single channel using the frequency range from 290GHz to 315GHz. Previously it was only possible to achieve such speeds by harnessing multiple channels at the same time.

    Yeah, 290-315 GHz is a channel bandwidth of 25 GHz 802.11ac at 5 GHz has a channel bandwidth of up to 80 MHz (e.g channel 155 is 5735-5815 MHz).

    Basically what they're doing is equivalent to "harnessing multiple channels at the same time." They've just elected to call their use of 312.5 80MHz bands a single channel, while if 802.11ac uses more than one 80 MHz band they're saying it's using multiple channels. Kinda like saying your road can only transport so many cars per lane, while my road can transport more cars in its "single" lane (which is 300x wider than your lanes, I just haven't painted lane stripes on it).

    802.11ac can (with a single antenna) manage 433 Mbps over an 80 MHz channel, or 5.4 bps / Hz of bandwidth. 105 Gbps over 25 GHz is then 4.2 bps / Hz of bandwidth. Since there's no improvement in bps per Hz of bandwidth, basically you could get these results simply by scaling up existing technologies to higher frequencies and greater bandwidth. (Higher signal-to-noise ratio allows channel data rate to exceed frequency.)

  3. Most if not all of those species went extinct because they were out-competed in their ecological niche by another species. Nature found a way - just via a different species.

    That's an important distinction here because as best as I can tell from TFA, these mice are the dominant creatures occupying this ecological niche (having killed off the flightless birds which used to occupy it). So killing off the mice will open up that niche to competing species. Likely, if this works, it'll result in a bigger problem with other species (maybe opossum or weasel?), or a new subspecies of mouse will develop which somehow sniffs out male mice with this gene and the females refuse to mate with them.

  4. Re:Looks like "cheap nuclear" is a bit more expens on Excessive Radiation Inside Fukushima Fries Clean-Up Robot (gizmodo.com) · · Score: 2

    Let's do a cost comparison as you suggest. Here's a graph of nuclear power generation over the last 45 years. Generation has been about 2300 TWh per year for the last 20 years. The 25 years before that ramped up roughly as a triangle, so call it 2200/2 = 1100 TWh per year average.

    This gives us a total of 73,500 TWh generated by nuclear power over the last 45 years. 20*2300 + 25*(2200/2) = 73500.

    Using a global average electricity price of $0.20 per kWh, this is $14.7 trillion dollars worth of electricity generated by nuclear over the last 45 years.

    Chernoby cleanup costs (current and future) are estimated to total $235 billion, Fukushima is estimated to be around $200 billion. Three Mile Island was about $1 billion. These are the only major commercial nuclear accidents in history, and their total cost is estimated to be $436 billion.

    $436 billion / $14.7 trillion = 0.02966. Or about 3%.

    So the cleanup costs for nuclear accidents is about 3% of the price of the electricity nuclear generates. Or 0.6 cents per kWh. This is so "excessively more expensive" that it would cost the average American home less than $8/year. (Average American home uses 10,812 kWh/yr * $0.12/kWh average electricity price * 20% of electricity produced by nuclear * 3% cleanup cost = $7.78/yr.)

    Insurers refuse to cover nuclear because of how statistics work. The more incidents there are, the narrower the bell curve and the more confident you can be about predicting how many accidents will happen. A 10d50 will be much more likely to yield a result near 55 than a 2d50 is to yield a result near 51. Consequently, even though their long-term mean is almost the same, a bookie will give you better odds on the 10d50 because it's more predictable and thus harder for them to lose money on it.

    Nuclear plants generate massive amounts of power. You need about 10 coal plants to equal a single nuclear plant. Several thousand wind turbines. Consequently you need much fewer nuclear plants to meet your energy needs compared to these other power sources. So even though statistically nuclear plants are safer than other power sources (mean accident rate is lower), their small number means there's larger uncertainty about how many accidents will happen. Insurers compensate for this by erring on the safe side (for them) and charging much higher rates. e.g. If there are 100 nuclear plants and the mean says 1 will suffer an accident in 30 years, the insurer may err on the safe side and charge a premium based on, say, 2 or 3 accidents, just in case they get a bad die roll. Whereas if there are 1000 coal plants and the mean says 10 will suffer an accident in 30 years, the insurer can be much more confident that even if they get a bad die roll, they can charge a premium assuming only 15 accidents and still make money.

    I ran a non-union shop. You need to document your reasons for firing regardless. If the ex-employee sues you for wrongful termination, you need to be able to prove your reasons for firing the person were legit. For minor offenses (things that don't warrant immediate firing), you need to show that you warned the employee multiple times. That's why the boss makes you sign that paper saying you were warned to stop showing up late - it's their documented proof that they warned you.

    As I said last time, this is not a positive stat for solar. Coal accounts for 33% of U.S. electricity production, vs 0.6% for solar.

  12. Paper has some useful properties that help it remain popular. If we can replicate or better these properties with technology, we can finally go paperless.

    Something like this was already invented about a decade ago and posted on slashdot. I'll repeat the info from what I thought was the most insightful post from that discussion:

    We shouldn't be trying to replace paper. We shouldn't even be recycling it. We should be using as much of it as we can and throwing it all away in the trash.

    • Why do we have a problem with global warming? Because we're digging up carbon that's been buried in the earth, and releasing it into the atmosphere as CO2.
    • Where does paper come from? Trees pull CO2 out of the atmosphere, and use photosynthesis (and water) to convert the carbon into wood. We cut down the tree, and convert that wood into paper.
    • What happens when we throw away paper? It gets sent to a landfill - it is buried underground. Drilled core samples from landfills have shown that newspapers over a century old are still intact and pristine inside the landfill. So this is an effective means of burying that carbon underground again. Microbes aren't consuming it and turning it into natural gas or something.

    So digging up and burning coal, oil, and gas removes carbon from the ground and puts it into the atmosphere as CO2. Throwing away paper in landfills removes CO2 from the atmosphere and sequesters that carbon underground. This is one of the tools in our fight against global warming, It's been proven to work, and unlike other sequestration tools which are all in the research stages this one is already widely in use. But because people just mindlessly jump onto the recycling bandwagon without actually thinking about if it's really a good idea, we're trying to shut down the most successful form of carbon sequestration we've invented.

    Use as much paper as you can. Throw it all away when you're done. The cost of the paper itself becomes a tax that funds the fight against global warming (pays for more trees to be planted to meet the demand for more paper). If you're recycling paper, you're making global warming worse.

That creates the illusion that the observer can move around the image in 3D, but the illusion only works for the observer being tracked. Anyone else sees a 2D image which rotates depending on where the designated observer moves, not based on where they themselves move.

Or how do you distinguish between someone finding out another person wants to visit their home town the same dates they're going to be on vacation so he agrees to rent his house, vs someone regularly renting a second home out as a business?

    In the old days, running a taxi or hotel commercially required advertising, and advertising meant mass exposure (mailers, billboards, TV). That made it easy for regulators to spot who was doing these things as a business. But like music distribution, the Internet destroyed that distinction. It dropped the cost of distributing information (e.g. music, or advertising) to near zero, allowing anyone running the above businesses commercially to advertise to people directly (spam, targeted ads, craigslist, Uber/Airbnb). It's a lot harder, if not impossible, for regulators to distinguish between two people coming to a friendly arrangement, vs someone secretly running a business.

So instead you make it a requirement that the company has to pay for a fraction of the employee's health insurance proportional to hours per week / 40. So if someone works 20 hours the company pays half their health insurance. If someone works 30 hours the company pays 75% of their health insurance.
