Taking the Ice Bucket Challenge With Liquid Nitrogen

anethema Re:fuck you and the bucket challenge (182 comments)

I cant even fathom the complaints about this.

Hasn't ALS hit like 100 times their usual funding for the year due to all these people dumping ice on themselves? Saying the popularity and viral nature of it aren't a benefit in itself seems short sited.

AMD Launches Radeon R7 Series Solid State Drives With OCZ

anethema Re: Low write endurance? (64 comments)

Sorry wrote it wrong but had it right in my calcs. I meant 30gb/day for 4 years.

It is 30 GB / day for 4 years which works out to 43 TB. Hopefully that makes it a bit more clear.

The point isn't that you may or may not use that much, its that their talking point is high endurance, and it actually has very low endurance compared to other consumer SSD lines.

AMD Launches Radeon R7 Series Solid State Drives With OCZ

anethema Low write endurance? (64 comments)

Their claim is they are focusing on reliability and write endurance but it looks like they have some of the lowest endurance in the industry.

Even the drive it is supposed to be a bit of a clone from is rated much higher.

AMD R7: 4GB for 4 years = 43TB (Odd that they don't say this is dependent on drive size, which it would be.
OCZ Vector 150: 50GB for 5 years = 91 TB (Also not scaled for drive size)
Samsung 840: 1000 cycles. In their smallest drive this would be around 120 TB. Samsung is using lower endurance TLC here so this is even more odd.
Intel 730: 70TB over their 5 year warranty is 127 TB Highest of them all for MLC.

Now in real life, the AMD and OCZ drives may go much further before they fail, but you have to go off of their ratings for comparisons or all hell breaks loose (Tests have shown the Samsung drives lasting over 3000 cycles before beginning to reallocate sectors). Especially for the larger drives (A 240GB drive should have double the write endurance of a 120GB drive).

So yeah I find it odd that endurance is one of their talking points when they have by far the lowest endurance of any of the common drives out there, including the supposedly very similar Vector 150.

Mass. Supreme Court Says Defendant Can Be Compelled To Decrypt Data

anethema Re:You talk, it's your fault (560 comments)

Well I mean, if you say you have an encrypted drive, you know the password, and the contents of the drive DO pertain to the case, you aren't incriminating yourself further to provide the key really. You have already plead guilty in a way, they just need the details.

Ask Slashdot: What Would It Take For You To Buy a Smartwatch?

anethema Re:all I'd need there is a sports iPod (427 comments)

Ya my current watch (Casio pathfinder ) is already pretty smart as far as watches go (has altimiter, barometer, compass) and half the face is a solar panel. I've not had to change a battery since I got it, and expect I wont for a long long long time.

Be nice if a smart watch could be rugged without being the size of a phone, and have solar or some kind of decent battery life. A month even would be nice.

Ask Slashdot: Do 4G World Phones Exist?

anethema Unlocked iPhone 5s does it all (259 comments)

O2 and Vodaphone appear to use LTE band 20 (SOURCE: AT&T and Canadian carriers generally seem to use bands 4 and 17 (same source).

The iPhone 5s does all of those and more. Model A1533 (GSM)*: UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 2, 3, 4, 5, 8, 13, 17, 19, 20, 25)

  (Source: )

I may be missing something but just buying an unlocked iPhone 5S from apple seems to give you all the LTE, HSPA, etc networks you could use in the UK and USA/Canada.

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: 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:

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

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?

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.

Android ported to iPhone

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  |  about 6 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 7 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."
