Comment that other Earth "like" planet... (Score 1) 104

FTA:

With a radius that is just 1.5 times that of Earth, the potential planet is what a so-called "super-Earth," meaning it is just slightly larger than the Earth.

Assuming it has a similar density to Earth, wouldn't it have considerably more gravitational force? Like, maybe 3x?

Earth's volume: 4/3 * pi * r^3 = 4/3 * 3.14159 * 1^3 = 4.1888
KOI 172.02's volume: 4/3 * 3.14159 * 1.5^3 = 14.137

People seem to forget that a small difference in radius produces a much larger difference in volume thanks to that r-cubed thing. "Slightly larger" equates to "much more massive" (given same density).
Or am I way off here?

Comment Risk is risky! (Score 1) 157

Is our society really so caught up in itself that we can't just admit we got scammed for a few bucks on a bet and walk away? Now Kickstarter has to do some CYA limbo so they don't get sued because they "enabled" scammers?

If you can't handle the risk, you don't deserve the payoff, and you shouldn't stick out your nose in the first place. Stay home.

Microsoft Patents Whacking Your Phone To Silence It 214

another random user writes with news of a patent application from Microsoft that details a method for silencing your phone by giving it a whack. "There are a variety of circumstances under which it may be desirable to quickly control a device without having to interact with a traditional user interface. For example, often mobile device users forget to set their mobile devices in a silent or vibrate mode and the device rings or makes sounds at an inopportune moment." And yes, 'whack' is the technical term used in the patent (20120231838): "receiving information indicative of acceleration of the mobile communications device; determining correlation between the information indicative of acceleration of the mobile communications device and exemplar whack event data; and based at least on the correlation, controlling an audio signal of the mobile communications device." This method is not recommended for controlling the audio output of animals or children.

My parents tool around the Bahamas every year in a Little Harbor 39'.

They've got at least three different GPS units; one built into the radar so you can match up coastal features with your charts, one built into the map desk, and at least two hand-held units (ala' Garmin Trek). Make sure the units you're looking at have digital sea charts available, as most of the hand-held units don't (or didn't last I checked) come with sea charts built in. The handhelds also have non-slip, brightly colored (yellow/orange) rubber protectors, bought separately.

You'll want to get into HAM radio, maybe even get a license. Definitely get one for home to try out, even if you buy a different unit for the boat.

Get eneloop batteries and a good charger or two. Also get a solar charger that you can roll out or pack away easily that will charge two AA's fairly quickly.

A wind turbine may be a good idea if you're planning to have a lot of tech gear, and almost certainly if you want a fridge with a freezer. However, most of them are noisy and getting a broken line caught in one while in bad weather will only make things worse. Also, if you have the wind to your back (generally speaking, sailing west) they won't generate as much (as if the boat were stationary) since you're traveling with the wind. If you're traveling east, you'll need more fuel to push it through the air (at a much less efficient rate than just running a more powerful generator off your engine).

An app like Night Sky that will super-impose constellation and astronomy info over a live camera image might be of use. (disc: that's the only app like that I've used and not much - not an endorsement, but it is a cool app)

If you're not already, become a: carpenter, plumber, electrician, mechanic, and eagle-scout level knot tying master. Practice doing separate skills with each limb while balancing on a see-saw.

Get used to making really detailed sailing plans and estimating how long it will take and how much gas and fresh water you'll need to get from point A to point B. Then flush those plans down the toilet. Repeat ad nauseam.

Lastly: have fun, it's great! :)

Comment Solution: taxes (Score 2) 500

Return Wall Street to be investment-oriented from trade-oriented. A 15% capital gains tax is too rewarding for a gain on stock that technically never makes it to the company it was supposedly and "investment" in, and thereby promotes trad-centered behavior.

How? By adjusting capital gains income (earned investment income) tax according to how long it was held:
less than 1 sec = 99%
1-5 sec = 98%
greater than 5 less than 30 sec = 97%
less than 1 min = 96%
less than 5 min = 95%
less than 1 hour = 93%
less than 4 hours = 92%
less than 1 day = 90%
less than 1 week = 85%
less than 1 month = 80%
less than 6 months = 70%
less than 1 year = 60%
[...]
greater than 10 years = 15%

and finally, and probably MOST important: make it Last In First Out - the most recent stock sold is the most recent stock bought. Pop the stack. Otherwise after 10 years it's right back to where it was.

Comment Comments matter (Score 1) 472

Good comments help capture what you're thinking; what you're trying to do with your code. That's far more important than the implementation. It's the 'why' not the 'how'. Anything that facilitates capturing the why is a good thing.

Case in point: regaining the knowledge of the Apollo program. they still have most of the designs of components, including multiple design revisions, but they never captured the reasoning behind the design changes. You can see that bolt moved a half-inch to the right, but you've lost why that move was important.

Sony Closes WipEout Developer Studio Liverpool 102

RogueyWon writes "Eurogamer is reporting that Sony has closed its subsidiary developer Studio Liverpool. Beginning its life in 1984 under the name Psygnosis, the development house has played an important role in the history of computer and video gaming, publishing classics such as the Lemmings series. Since its acquisition by Sony in 1993, the studio has been best known for its work on the WipEout franchise, which helped to establish the PlayStation console as a successful brand. Sony's statements indicate that it will seek to find positions for staff in its other development houses, but that some redundancies will be necessary." Eurogamer posted an update, indicating that the studio was working on WipEout for the PS4.

Virtual Nanoscopy Allows Scientists To Capture High Res Cell Map 16

hypnosec writes "Researchers have managed to generate ultra-large high resolution electron microscopic maps of cells by developing new tools that can combine thousands of images taken from an electron microscope thus enabling them to view a cell in its entirety. Use of electron microscopes reveals intricate structures of cells, but with a limitation that only a tiny portion of the cell is captured, which misses the bigger picture. If low-res images are captured to view a greater part of the biological structure, intricate details are missed. A team of scientists over at Leiden University Medical Center in the Netherlands has come up with a technique called 'virtual nanoscopy' that enabled them to ultrastructurally map regions of cells and tissue as large as 1 mm^2 at nanometer resolution."
