Ask Slashdot: Where Can I Find Good Replacement Batteries?

w0mprat Always buy spares when you get a new phone: (131 comments)

A tip: When you get a new smartphone these days, buy one or two spare batteries while they are widely available, and well before the device is deprecated and hard to find a good battery for, let alone an official one. Store your spare li-ion batteries with a half charge, and/or just alternate use of the batteries. Spare accessories are also a nice selling point if you upgrade and want to sell your old phone on ebay, or to a friend.

Li-ion batteries lose about 20% of their lifespan every year, I've had plenty that die faster, perhaps due to much more intense cycling and usage. Having spares you rotate means you'd still have most of your battery range after a year of ownership.

Perlan II Project Aims To Fly a Glider To the Edge of Space

w0mprat Re:100km (44 comments)

At 27km up, you're closer to ground than to the edge of space. Stop sensationalizing.

At 27km up your above 98% of the atmosphere if you go by density. It's not sensationalizing at all.

Aliens and the Fermi Paradox

w0mprat Re:Progenitors? (686 comments)

The Fermi paradox baffles me because it is quite easy to solve. The simplest explanation in my mind, is that faster than light travel is either just not possible or if possible requires astronomical amounts of energy that it just isn't worth it for the scientific gain (because you are not going to do battles or trade over that distance the only reason to travel is curiousity).

Thus no matter how full of life the universe is, it just almost never gets to meet up for a party.

Mathematical Model Suggests That Human Consciousness Is Noncomputable

w0mprat Re:Bad syllogism (426 comments)

Baloney. What a stupid argument. Here is it, summarized: 1. Here is one mathematical model of a way that memories could work. 2. This method would be computable. 3. But that would mean memories degrade the more you remember them 4. But memories don't degrade the more you remember them. 5. Therefore memories are not computable.

Assignment for the student: find the flaw in this argument.

On point 3. is this not how pretty much any volatile memory in any computer biological or artificial works? Our brains are not exempt and seemingly have to re-inforce/re-write memories as accessing them probably does indeed cause them to degrade.

Mathematical Model Suggests That Human Consciousness Is Noncomputable

w0mprat Re:Ghost in the machine? (426 comments)

"Non-computable" does not mean "non-copy-able". In other words, consider the sort of consciousness associated with recognizing oneself in a mirror. Humans are not the only animals that can do that. Among those that can are quite a few other primates, dolphins, elephants, some species of birds (certain parrots), and even the octopus. So, think about that in terms of brain structure: Birds have a variant on the basic "reptilian brain", elephants and dolphins have the "mammalian brain" extension of the reptilian brain, chimps and gorillas have the "primate brain" extension of the mammalian brain, and the octopus brain is in an entirely different class altogether (the mollusk family includes clams and snails). Yet Nature found ways to give all of those types of data-processing equipment enough consciousness for self-recognition. And after you include however-many extraterrestrial intelligences there might be, all across the Universe, well, anyone who thinks "no variant of computer hardware will ever be able to do that" is just not thinking clearly.

Personally my guess is consciousness is an inevitable emergent property of any sufficiently complex information system that is highly integrated in a certain and special way. It's an advantageous property so evolution naturally selects for it. Ergo it pops up in multiple places in the evolutionary tree.

This research merely seems to be setting some bounds. You can't reduce human experience in to something convenient to compute, at least not without losing a lot of fidelity to be useful, you still need to build an equivalently complex brain.

Yes anyone thinking clearly sees it isn't ruled out computer hardware cannot achieve the same feat. It's just shortcuts have started to have been ruled out. It seems some people are interpreting this research as evidence against machine awareness, which I don't think as supportable, it stems from the faulty as assumption the human brain is somehow special and privileged with physical law that don't apply elsewhere in the universe.

You Are What You're Tricked Into Eating

w0mprat Re:Ass time (499 comments)

Cooking is more a test to your capability of organisation and laziness than having the time.Many meals are simple to cook, or then take your ipad or TV to the kitchen, and cook while you watch idols or Game of thrones. The problem with cooking real food is that many are lazy, and others the parents already didnt do that, and they dont really are not used to do it. The culture of buying everything already made is very pernicious when we are talking about what we eat.

Cooking itself can be a fun and rewarding task itself. I find it quite relaxing way to de-stress after a hard days work behind a glowing screen, to be able to throw stuff around a 3-dimensional space and engage senses of taste, feel and smell. I can crank out a tasty meal from fresh produce quite quickly. It's cheaper than anything out of packet, is going to extend mine and my families live and prevent debilitating disease suffering and death, and I feel pretty ace when I've nailed a new technique.

The major problem is people have become too accustomed to reward for no or little effort. Open a packet, push buttons microwave, ding ding and your done. I ponder if, partly, we over eat portion wise where the food is too accessible, simply because the reward factor of acquiring and preparing the food is missing.

Food just tastes better when you've put some effort and flare in your self. The whole process needn't be a chore at all.

(This perhaps explains why some useless cooks seem to think their own food tastes good to them, despite others not quite agreeing.)

I humbly present the solution: gamification of food.

Atlanta Man Shatters Coast-to-Coast Driving Record, Averaging 98MPH

w0mprat Re:When will he be arrested? (666 comments)

No, highway speed limits, at least federal interstates, have speed limits for the purpose of generating revenue.

Reckless driving is a criminal offense, not something you're fined for. Speeding fines are there to provide some disincentive to doing stupid things prior to going to jail for it.

And revenue. As minor speeding isn't really much danger at all, but a lucrative cash cow authorities have become accustomed to suckling the milky teats of.

You'll find speed cameras and cops hitting motorists hard in places where people are likely to speed, and there for generate maximum revenue. But conspicuously absent at notorious deadly accident blackspots where there isn't a high volume of traffic.

If the primary goal was to save lives by slowing people down. Using first principals, where would you decide to put a speed camera?

No, the Tesla Model S Doesn't Pollute More Than an SUV

w0mprat Re:Same as last time (559 comments)

When the Prius first got popular the same thing was said about it. Was soon proved false.

Indeed. The massive environmental impact of the battery pack was part of that criticism, but this is also where electric cars win, if one is being honest about the numbers and don't have a anti-electric car axe to grind: The NiMH battery pack of early hybrids is pretty much 100% recyclable. Li-ion and Li-po etc isn't properly 100% recycled at the moment but that's a infrastructure problem - theoretically 100% recyclable. (I would imagine some years down the track used battery packs would be quite valuable scrap). You just cannot say as much for the hydrocarbon fuel going through the tank of a regular automobile.

A Tale of Two Tests: Why Energy Star LED Light Bulbs Are a Rare Breed

w0mprat Re:Why light bulb form factor? (314 comments)


(1) you don't have to pay an electrician to remove and reinstall a lamp, but you do a fixture (2) you don't disrupt the flow of business and it takes a shorter time to re-lamp than replace a fixture (3) if you find that the LED sucks, you can go back to what you know works (4) In 10 years, when one (or more) of the 30 year life fixtures dies and they don't make that model any more, I can replace a lamp and the fixture will still look the same. If I have to replace a fixture, then I have an oddball looking spot in my ceiling. Not everything is a warehouse where aesthetics mean nothing.

Oh, and there are a good number of older consumer fixtures which either (a) anticipate a certain light pattern or (b) actually use the lamp as the structure to hold the shade. I you think it's hard to convince people to buy a $20 lamp instead of a $1 one, it's even harder to get them to buy a new $60 fixture to put it in.

But even with the same socket type and it's dimension limitations why does it still need to be round and bulb like? A spherical bulb is the worst case scenario for heat dissipation, other shapes would perform better. Many LED bulbs have a cluster of LEDs often with some lens over the top of them. To me that allows a lot of freedom for heat dissipation considerations. But it's not a lack of imagination from manufacturers, they are just are playing it safe by assuming consumers won't accept odd shaped lights.

I find LED spots and floodlights have less of a problem as there is room for a heatsink. Yet MR16's get so hot it scares me.

HBO Says Game of Thrones Piracy Is "a Compliment"

w0mprat Re:No shit (447 comments)

Finally a Slashdotter that understands piracy both helps and also hurts, especially when the legal means of consuming the content covers most of the intended market.

Helps mainly. Hurts barely at all. Thought we didn't get a Slashdotter that mentioned merchandise - the tangible goods (including the George R.R. Martin books) that get purchased by people who may have never paid a penny for the original content. Often a merchandising empire is a vastly bigger source or revenue than the original legal means of consuming the content. This is becoming the case with GoT.

The occasional Slashdotter will point out the war on piracy was never about lost revenue, it was about profit maximization, and in the case of DRM for example, about leverage over equipment manufacturers (any prevention of casual copying was a small bonus). Example: Apple's declaration that DRM had failed, and subsequent was not some cathartic pro-user move, but rather they are a huge content consumption equipment manufacturing when they became powerful enough to dictate terms in the opposite direction, they through DRM it right back in the freakin' content industries face.

Richard Plepler may see piracy as a background noise HBO has to live with - but one that is actually helpful, possibly lucrative if played right.

New Facebook-Branded Android Coming?

w0mprat Re:So, (112 comments)

Lots of apps latch on to a myriad of system events so they can relaunch themselves - some are fairly obscene in how they go about this.

One good solution is to install "Autorun Manager" - it allows you to disable the receivers on a per application basis. Once you kill something, it stays dead until you explicitly start it again.

Also recommend using the app freeze feature in Android. Requires root on most devices but this useful trick "Freezes" an app without actually uninstalling it, it becomes invisible to the system and cannot execute. Some apps like App Quarantine, Titanium Backup and Hide It Pro offer a convenient way of doing this. This means you can have Facebook or some such app, but prevent it from running when you aren't directly using it.

There's a reason most scientists use the more accurate term climate change.

And not "Weather change"!
Weather != Climate. Some mention of Weather extremes inevitably gets linked to Climate extremes. Some comment that ammounts to "It's colder today than and by next week it will be an ice age!"
There is huge difference between Climate and Weather.

Can You Really Hear the Difference Between Lossless, Lossy Audio?

w0mprat Re:Depends on the source (749 comments)

Your preference for 24/96 audio as a listener is entirely due to the placebo effect.

Well, in all fairness, listeners may actually hear perceptible differences between 24/96 and 16/44.1 audio sources due to different mastering, but of course that says nothing about whether they can actually tell the difference between the two bitrates when everything else is equal.

This article is a pretty good explanation of why 16/44.1 is as good as anyone needs for playback.

There's plenty of articles from "experts" on why 16/44.1 is all you need, however these kind of opinions risk being being wrong: What about actual data? I see little solid data where the hypothesis has been put to the test.

I think the point is, some say 24/96 survives lossy compression better, it also produces less artifacts as the higher frequencies have less data points to describe their waveform. Perhaps some won't hear the difference in uncompressed audio, but I bet some can hear the difference in compressed.

Samsung Also Making a Smartwatch

w0mprat Sony already makes a smartwatch. (196 comments)

Sony already makes and sells a SmartWatch. This seems to have gone completely unnoticed by the blogosphere, who keep using terms like "first to market" and "new category" and don't seem to be able to use a Google search to see whats already out there. Sony's Smartwatch also is the benchmark that Apple will copy pretty much everything from, including the way it syncs with your existing Android phone and bluetooth gadgets. (You can bet it will do less cost too much, just prettier, and sell millions more).

Apple seems to pick on poor Sony, they already stole Sony's idea with a one-brand retail outlet. (Sony Style stores opened in the 1980s - decades before Apple Stores). Apple's original iPhone was almost as similar to some of Sony's touch screen concept phone, that you you wonder. Now they'll copy the Smartwatch.

Samsung has some very cool display tech though, such as flexible screens - there's a damn good reason why they aren't in Sammy's new phones (S4 etc). I would put good money on Smartwatches being the first use of these screens and that's where production resources are being directed right now.

Unless Apple uses AMOLED for their watch, Samsungs going to be the winner.

Laser-like signal from Gliese 581 in '08

w0mprat w0mprat writes  |  more than 4 years ago

w0mprat (1317953) writes ""Just about a year ago Ragbir Bhathal was scanning the night sky for alien activity, just as he does every night. Except on this December eve Ragbir Bhathal found a strong, regular, repeating signal.... Unlike most of the tin-foil hat wearing whackadoos in his field, Dr. Bhathal is a hard scientist working with university money to find extraterrestrials...As proprietor of OZSETI, Dr. Bhathal combs the universe in search of light signals, not radio transmission"

The star system in question is none other than Gliese 581, where a earthlike planet was reccently found. Bhathal has only detected this signal once, while it has been verified by a signal processing specialist to be a real signal, it has not been seen again. Bhathal has a strong case for his decision searching around the visible spectrum, something like a laser may stand out as almost unambiguously artificial. He may have indeed found just that.

In this article from '09 they specifically mention the planet's name, Gliese 581e. They claim this 'e' planet was too close to its sun to be habitable. http://www.theaustralian.com.au/news...-1225710664198

This recently discovered 'goldilocks' planet is Gliese 581g. Same fracking solar system!
