Apple To Unveil Its 'iOS In the Car' Project Next Week

anethema Apple Maps (198 comments)

"Drivers will be able to use Apple Maps as in-car navigation"

Not sure how that compares to most in-car navigation, but Apple maps is still a pile of garbage. They maps are much harder to see than googles, the POI database is terrible, the routing is unusable, at least in small-town Canada.

Be interesting to see what they come up with but I sure hope it has an App store to switch out the maps.

Japanese Firm Proposes Microwave-Linked Solar Plant On the Moon

anethema Re:Gravity wells and other distance issues (330 comments)

Actually you are understating the difficulty of transmitting that power.

There are several big problems. One is real world rectennas are not that efficient. The best best lab condition ones with lower power are 90% but high power ones are quite a bit less, sometimes up to 75 percent or so.

The other massive loss is transmission loss. The basic formula is 32.45 + 20log(d) + 20log(f). Using the 1.32 TW estimate in this post: http://science.slashdot.org/co... and a rough 24ghz given in this page http://www.propagation.gatech.... we would have around 231 db. Considering you are starting with 121 dBW of power, you are left with -110dBW of power on earth not accounting for antenna gains.

Since a watt is 0dBW, we need 55db of dish gain on either side to get 1 watt and a gain of 115 to get the input power generation. At 24 GHz this is a 3 KILOMETER dish on either end. The largest parabolic on earth now is 0.3 km, so ten times that. Plus it would have to always point at the moon (how? No idea).

Plus You would lose your 50% or more since obviously the whole equator isn't facing the sun. Then the 50-70 from your rectenna loses.

I imagine a bunch of other stuff from other losses I havent taken into account (Convert to AC, line loss, whatever else) and I cant imagine this being feasable.

Ask Slashdot: What Games Are You Playing?

anethema Re:There are several good indie titles (669 comments)

I actually found its not really like Cod at all.

There are similarities, like there would with any shooter. But there is parkour like running around (Like Assassins creed, but first person), jetpacks (due two these two, you have to think very vertically, or get killed very often), cloaks, "burn cards" which grant cool abilities, plus the obvious very large titans running around.

First Recorded Observation of Freshwater Fish Preying On Birds In Flight

anethema Re:Beware the CSI effect. (93 comments)

Yeah I really enjoyed the behind the scenes stuff of the BBC Planet earth showing the sharks catching the seals.

They aren't sure where/when/if it is going to happen, so catching the shots was tough.

They had a cool high speed camera that was always recording, and when they hit the button to get their slow-mo footage, the video camera recorded 2 seconds BEFORE and 2 after they pressed it, otherwise they would never have been able to get the whole event.

Pretty interesting.

Is Earth Weighed Down By Dark Matter?

anethema Re:geostationary GPS satellites (247 comments)

They are absolutely not geostationary. The whole reason your GPS needs time to 'lock' when you haven't used it in a while is it is downloading the orbital path(Ephemeris) data from the satellites themselves. Once it knows where they should be at which times exactly, it knows where it is relatively.

So basically, none of them are geostationary, unless you count ground based DGPS stations, that obviously don't move haha.

CES: Laser Headlights Edge Closer To Real-World Highways

anethema Re:Awesome (295 comments)

You don't actually have to replace the housing to get this though. The proper retrofits put a projector lens inside your current housing.

These for example are designed to be modified into stock housings: http://www.theretrofitsource.com/product_info.php?products_id=141

Also if you've seen a HID Xenon bulb, the ball inside that makes the light is bigger in almost every dimension as compared to a filament in a Halogen bulb. This is why the light tends to be a bit unfocused in a halogen housing without a projector, just the stock reflector. But even still most of the problem comes from the fact that they are just twice as bright. You see much of the same glare with a halogen installed it is just too dim to be annoying.

Smooth, 6.5 Hour Spacewalk To Fix ISS Ammonia Pump

anethema Re:Seeing the gravity is only 1/6th up there (90 comments)

Yeah it is surprising how many people think there is no gravity in orbit.

Gravity is only reduced by roughly 10 percent at that distance from earth. The reason it seems like there is no gravity is you are always falling towards the earth. You just happen to keep missing !

Do a retrograde burn and you will stop missing quickly though.

Diet Drugs Work: Why Won't Doctors Prescribe Them?

anethema Re:They are scared (670 comments)

Of course you will be more tired. But if you keep up your routine with your caloric intake way down, then you will lose weight. You have to. If you were not gaining weight on your old diet, with the same routine as now, the food has to go somewhere.

Now doing the same things with less calories, you can't maintain weight, your body will burn it.

Why Cloud Infrastructure Pricing Is Absurd

anethema Re:Why even use cloud services ? (191 comments)

You can also go the other way and spec your equipment for the massive seasonal peaks then rent out out as a cloud service for others later :D (IE: Amazon)

Diet Drugs Work: Why Won't Doctors Prescribe Them?

anethema Re:They are scared (670 comments)

You still maintain weight if you take in less calories than you're burning.

If she is near immobile most of the day, she should need very few calories.

Look for places you can cut calories out of the diet and look for exercises that can be done mostly with upper body.

Scientists Boost the "Will To Persevere" With Current To the Brain

anethema Re:Impossible! (127 comments)

I'd rather have willpower.

Those who do well in school and life, are not the most intelligent, but the ones with the most willpower to see things through.

Something I've never had the most of unfortunately :(

Death to the Trapezoid... Next USB Connector Will Be Reversible

anethema Re:Even worse... (408 comments)

Inductance.

ALL the power that goes into your home is transmitted wirelessly over the short distance between the coils in a transformer outside.

It uses inductance to move power from one coil to another, and the Qi works the same way.

It is actually fairly efficient and can change the voltage at the same time. Win-win!

Samsung Unveils Galaxy Gear Smartwatch

anethema Re:Fire Sale (244 comments)

My Casio Pathfinder ( http://i219.photobucket.com/albums/cc18/gaijinnv/PAW2000_Zulu_16OCT09.jpg not my pic, but same watch/strap I use ) has basically infinite battery life since it is charged via solar. I live in northern Canada, and even in the middle of winter where the days are like 6 hours, and I'm in winter clothes, the batt indicator is never off full.

Of course, it also has altimiter, barometer, compass, thermometer, and syncs nighly with the atomic clock in colorado.

It would take something pretty hefty to knock this off my wrist.

At Current Rates, Tesla Could Soon Suck Up Worldwide Supply of Li-Ion Cells

anethema Re:18,650? Really? (351 comments)

Ya. Just in case it isn't obvious, 18650 means 18mm Diameter, 65mm length, and 0 at the end indicates a cylindrical cell. AA batteries are 14500 sized, and CR123's are 16340s.

I use 18650s and 26650s in all my flashlights. Lithium is cheap, bright, and long lasting compared to AA NiMH. Love em!

Ask Slashdot: When Is It OK To Not Give Notice?

anethema In Canada.. (892 comments)

Here in Canada, if you don't get to keep working for your notice period. They have to pay you your wages you would have worked if they just 'escort to the door' as you say.

Nice to have at least rudimentary labour protection laws.

Despite Global Release, Breaking Bad Heavily Pirated

anethema Re:How many knew that it was a global release? (443 comments)

If you want to watch English shows, learn English well enough to do so, or watch subtitled.

Dubbed shows are always horrible, the acting is unlistenable, and really throws the vibe off.

I never watch anime for example dubbed, only subtitled even though my Japanese is very spotty.

That being said I don't know if the English version is available there either, but just sayin haha.

Moto X Demo Video Reveals Google's Android Superphone

anethema Re:So it listens all the time... (151 comments)

Really? Because the ARM white paper seems to indicate otherwise.

http://www.arm.com/files/downloads/big_LITTLE_Final_Final.pdf

"In the big.LITTLE task migration use model the OS and applications only ever execute on Cortex-A15 or Cortex-A7 and never both processors at the same time."

Says it takes about 20 microseconds to switch at 1GHz operating frequency.

It is invoked by setting a power state level and only 4 cores are ever presented to the OS.

There is a type called big.LITTLE MP which presents all 8, but I've found numerous sources(http://arstechnica.com/gadgets/2013/03/samsungs-exynos-5-octa-checking-out-the-chip-inside-the-galaxy-s-4/ to start) saying the S4 does not use this at all. Maybe with a kernel recompile it could be done, but isn't currently.

Android ported to iPhone

anethema anethema writes  |  more than 3 years ago

anethema (99553) writes "iPhone hacker planetbeing, from the iPhone Dev Team has successfully ported the Android OS over to the iPhone. He is doing it on a first generation iPhone, but others may be possible. The port is pretty functional, with data, voice, and many apps working, although it is running a bit sluggish and buggy at the moment, since there appears to be much work left.

Any donations of time, money, or code I'm sure would be appreciated."

How to work exclusively online?

anethema anethema writes  |  more than 5 years ago

anethema writes "I've been thinking for a while about making a change in that I would like you get away from my 9-5 and try to get a job exclusively online. This would allow me to get away to places I've always wanted to go, but still work for a living.

I have thought of various ideas even up to trying to think of a novel porn start-up or some kind of telecommute type job over VOIP, but nothing has really jumped out. My skill set unfortunately lies in the electronics and practical RF radio fields, but I am willing to learn new skills and work hard for my goal.

Has any slashdotter broken away from the brick & mortar grind and made a living for themselves such that they never had to leave their home, or (my goal) been able to leave the country while still working online?"

FTC Nixes Net Neutrality

anethema anethema writes  |  more than 6 years ago

anethema (99553) writes "The Federal Trade Commission has decided that there is no demonstrable harm to the consumer posed by a lack of net neutrality, and so has decided not to enact any regulations on the subject.

From TFA:

"In the absence of significant market failure or demonstrated consumer harm, policy makers should be particularly hesitant to enact new regulation in this area," FTC Chair Deborah Platt Majoras wrote.


I guess having to pay to have artificial caps removed, causing many services to go out of business or raise their prices doesn't hurt the consumer."
