Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life

luckytroll Lithium Titanate batteries are not new. (395 comments)

The existing variations on this tech are faster to charge because of increased interactive surface area, but they have less energy density.

As trade offs go, this puts more of a strain on the charging infrastructure, as you get batteries that charge faster, but need it more frequently. If this tech can increase the lifespan, it could bring prices down, but I would prefer to get my cake (high energy density) and eat it too (high charge/discharge currents possible).

Drone-Assisted Hunting To Be Illegal In Alaska

luckytroll Well, glad the drones arent doing the shooting yet (397 comments)

At least folks are still getting out in the fresh air.

Seems like its only a matter of time before people can just sit in their living rooms and run an armed drone around the bush to shoot stuff for them.

It already happens a bit with the astronomy crowd - why stand shivering when you can remote your telescope from the comfort of home?

On the plus side, if you do happen to design a drone smart enough to hunt down a critter, you may have a future building dystopian tech for the defense industry.

Top U.S. Scientific Misconduct Official Quits In Frustration With Bureaucracy

luckytroll Been there, quit that. (172 comments)

I spent a lost year of my life working for a similar agency. The systematic fear and redundant covering of asses made for endless meetings.

The only thing worse than busywork is busywork with a profound sense of importance attached to it.

With XP's End of Life, Munich Will Distribute Ubuntu CDs

luckytroll Ubuntu 12 on old XP machines - 32bit problem. (426 comments)

This is a nice sentiment by Munich, but the many of the folks who are running XP and try and install Ubuntu 12 will be in for a nasty surprise -

32 bit machines without PAE will not load with most newer Linuxes. Most, including Ubuntu, no longer include 32 bit non-PAE kernels in their installers.

I found this out when I tried putting a modern albeit tiny Linux onto my FitPC 1 and an older EPIA motherboard - XP runs fine on these, but finding a linux is probably beyond the skill of most XP users. Jury rigging a different kernel in is definitely out.

A lot of older XP installs are also running on older hardware. Just giving away an OS will not magically fix this. And if these folks upgrade the hardware, it probably comes with a newer windows anyway.

Retail Stores Plan Elaborate Ways To Track You

I find it unlikely that the Salvation army or Value Village would bother with this technology, let alone actually be able to offer clothes that match.

New Thermocell Could Turn 'Waste Heat' Into Electricity

luckytroll Re:TAANSTAFL! (181 comments)

I could totally use a version of this - I would wrap it around the exhaust riser on the diesel, and then cool the other side with incoming cooling seawater before it entered the cooling heat exchanger. The difference would be 400C inside vs 22C outside, and might be able to generate some more energy from the waste heat.

I also considered running ammonia through this hot spot and making it an adsorption refrigerator, but that can generate some interesting (chinese) pressures, which can be a hazard.

Of course, normal folks just put an alternator on... but why be normal!

UCSD Lecturer Releases Geotagging Application For "Dangerous Guns and Owners"

The entire USA, but it seems to want more specific coordinates.

But seriously, a name-and-shame app for people who are afraid of firearms seems a bit futile in the USA. It would be like a Jew in early 20th century Germany making an app to tag anti-Semitic individuals, institutions, and businesses....

Why PC Sales Are Declining

luckytroll I blame the Gema Consoles (564 comments)

Lets face it, the average user and business PC are serviced well enough by Windows 7, or even XP. So who is left to chase the gains brought by Moores Law?

The PC gaming enthusiasts, thats who. And why are those guys for the most part sticking with the same PCs?

Because most PC games are locked to the performance of a game console - Xbox, et all - and those are a little long in the tooth themselves.

Until the next generation of Consoles pushes the envelope of hardware, and the game developers follow suit... PCs will have no reason to follow...

Why Your IT Department Needs To Staff a Hacker

luckytroll Re:To some extent, yes (241 comments)

You quipped -
"What, why do we need a SAN? Remember how you wired those netbooks together for our web farm! Figure something out for us. KTHXBYE.'"

- I think the guy who got that line went on to invent iSCSI.

Not that I have anything against Fibre Channel --- as long as the buffer credits dont run out.

Researchers Push Implanted User Interfaces

luckytroll Bluetooth Zombies? (84 comments)

Neat technology, but the use of cadavers is a little disconcerting.

Now we will have to fight off bluetooth and WiFi enabled zombies in the coming apocalypse.

Luckily for us the Zombies will probably be content to use WEP and 2GHz. No worries!

I am preparing for Hurricane Irene ...

luckytroll Re:It already hit me.... (147 comments)

It wasnt expensive, actually. Old steel boats are really cheap these days, if you can stand all the rust. It isnt critical to livelihood, but it allows me to live part of the time in a sustainable fashion, away from winter. Living that way teaches lessons in conserving every Amp, litre, and hour of the solar power, fresh water, and time left.

I am preparing for Hurricane Irene ...

luckytroll It already hit me.... (147 comments)

My boat in the Turks and Caicos got nailed - 30 miles from the eye. According to the folks there, things are alright. Ill believe it when I see it. This is my third Hurricane - we have weathered Earl last year and one a couple years before that. Our secret to survival - lots of rope tying down lots of heavy tarps covered with sacrificial tarps - and everything cauled and tied down.

This year we also used kevlar straps to hold the boat in place. Other years we dug a pit and put the boat in.
In all cases, the solar panels somehow stayed attached and keeping the batteries floating.

Bionic Body Parts For the Disabled

Who wants an arm that occasionally throws feces at people. Quite embarassing, and all you can say is "Sorry foks, my bionic arm is controlled by a monkey, and hes pissed today"

Google TV Next Month, Boxee In November

luckytroll XBMC - Now! (132 comments)

I dont see the point of either of these "services" when we already have a decent and open solution that solves most of the issues I had with "TV" - advertising contaminating my content.

XBMC with a few plugins (Which is basically what Boxee is) and a well stocked media library from the torrents/usenet gives me all the television I could want, all the web content I can chew - and NO fscking adverts!

What are Google and Boxee except that, plus advertising put back in? What value can they possibly insert that would make it worth my while to get screaming mad ad annoying ads again? None.

Avoiding GM Foods? Monsanto Says You're Overly Fussy

luckytroll Re:About that DSM classification (835 comments)

True, but the intent is to characterize mental illnesses so that they can be identified and treated. My friend would have snuffed it had there not been intervention by doctors. For the people who suffer this specific form of illness, there is often little or no help from doctors until they are literally at deaths door because their dietary choices cannot be readily pidgeon-holed into a diagnosis that indicates action. If she had had classic anorexia they would have had some traction because they have that one classified already. TFA makes valid points about people who are suffering - and while Monsanto et all may try and use the disorder to stigmatize everyday people who care about what they eat it dosen't lessen the fact that it is a disease and the people who suffer from it need help, sometimes badly.

Avoiding GM Foods? Monsanto Says You're Overly Fussy

luckytroll About that DSM classification (835 comments)

The Monsanto arguments all have a lot of merit, and we should be working to fix that aspect of our agriculture.

However, blaming them for the DSM categorization of picky eating is a bit beyond. I had a friend who suffered from this picky eating disorder and it was horrifying. It started with vegetarianism, then veganism, then avoidance of an increasingly expanding list of politically incorrect foods. Eventually she became a skeleton who had to be fed through an IV because she was eating little more than a couple very specific kinds of white rice. With treatment, they managed to get her back to a surviveable diet, but it was a close shave. It wasnt anorexia per se - it was something else that Doctors need to be aware of. Making informed choices that make the world a better place and make ones diet more nutritious is one thing - succumbing to a psychological disorder like picky eating is way different.

Quantum Dots Could Double Solar Energy Efficiency

luckytroll Could, might, may... (112 comments)

If I had a tribble for every time one of these solar energy articles came out with their pages full of nothing.... I could make a lot of fur coats.

Could someone in the research field please hold on to their excitement until they can post a report that has words like "WILL, SHALL, DEFINITELY, HAS, IS" instead of the wimpy "could, may, might, has potential to, in 5 years if all goes well....."

I got sucked in by one years ago and pestered the company for information about their new "product" which was due out "soon".... and that was nearly 10 years ago.

So many advances in tiny little cells on a research bench, and so many promising advances. Yet none of them seem to show up at the local hardware store.

I understand that advances in quantum materials science is cool, and can change everything just like the invention of the transistor did once. But seriosly folks - the number of speculative postings based on
these barely germinated lab experiments seem a little bit like the kid who cried "Solar revolution", or was that wolf?

McDonald's, Cadmium, and Thermo Electron Niton Guns

luckytroll Re:XRF is not a replacment for labratory testing. (206 comments)

There are a lot of methods that can ameliorate this, especially if you take samples of the soil back to the lab and process them for grain size, etc.

Nevertheless, if you have a lot of experience with this, you might find a chat with my spouse interesting as she has done extensive analysis of the effectiveness of XRF vs ICP etc in her work of late, notably relating to lead and manganese. So far the Niton units stack up pretty well against ICP if the samples are processed well.
