Submission + - John Goodenough responds to skeptics of his new lithium-on battery (computerworld.com)

Lucas123 writes: John Goodenough, the University of Texas researcher who this week demonstrated new battery cells that are safer and have at least three times as much energy density as today's standard Li-on batteries, responded to skeptics who said the technology described in research published in a peer-reviewed journal, appear to defy the laws of thermodynamics. In an article published Monday by Quartz , various energy experts took exception to Goodenough's claims, even calling them "unbelievable." Goodenough is also co-inventor of the original lithium-ion battery. In an email to Computerworld, Goodenough said "any new discovery invites strong skepticism." In this case, the skeptical scientists wondered how it is possible to strip lithium from the anode and plate it on a cathode current collector to obtain a battery voltage since the voltage is the difference in the chemical potentials (Fermi energies) between the two metallic electrodes,. "The answer is that if the lithium plated on the cathode current collector is thin enough for its reaction with the current collector to have its Fermi energy lowered to that of the current collector, the Fermi energy of the lithium anode is higher than that of the thin lithium plated on the cathode current collector," Goodenough said.

If you DON'T stay current, then you have as little choice as to what happens to your linux kernel and distro as any Windows user has over their OS.

Not quite true. I don't care about kernel release notes and distro package changes until they matter. That is, it either breaks something I care about, or adds something I care about. When it comes to things I care about, I have complete control over my own computer.

And that's all that matters to me. (By definition) If I can't configure one distro to suit my needs, there has always been another one available.

No one has time to go through every single fucking line of code for every driver, utility, application, etc. So you end up "trusting" the open source community.

Open source doesn't mean the code is perfect. I don't think anyone believes that. There will always be security holes, whether added maliciously or accidentally, in virtually every operating system I am aware of. But that's not the same as having the vendor introduce unwanted features, or deliberately degrade user experience, or preventing the user from modifying their own settings, or preventing them from running software that didn't come from an approved app store. ...all of which have been done in recent years. It's gotten to the point where it's debatable who actually owns the computer, you or the OS vendor.

I have not seen this to the same extent in open source OSes, even including Android.

Some of us would rather skip the illusion of safety and open-ness and get on with our lives without kidding ourselves.

Safety is never guaranteed with code of any significant complexity. Openness can be.

Submission + - ASK SLASHDOT: Which VR system is worth the investment? 1

Quantus347 writes: Straightforward question: I held off for a year to let the various manufacturers shake out the bugs, but now it's down to either a VR system or a new gen console. So I ask you, the Slashdot community, what are your personal experiences with any of the various VR systems out there? What are their strengths and weaknesses? What little things annoy you the most? What features make a given product the best (or worst) option?

Submission + - The Manhoff Archives: Stalin's Soviet Union comes to life in full color (rferl.org)

schwit1 writes: Major Martin Manhoff spent more than two years in the Soviet Union in the early 1950s, serving as assistant army attaché at the U.S. Embassy, which was located just off Red Square at the beginning of his time in Moscow.

He took full advantage of his post, using his gifted photographic eye to capture hundreds of images of everyday life in Moscow and across the U.S.S.R.

When he left the country in 1954 amid accusations of espionage, Major Manhoff took with him reels of 16 millimeter film and hundreds of color slides and negatives he shot during his travels – including of one of the Soviet Union's pivotal events, Josef Stalin's funeral.

But after his return to the United States, the trove of rare images lay forgotten, stored in cardboard boxes in a former auto body shop in the Pacific Northwest until its discovery by a Seattle-based historian.

Submission + - Norway says half of new cars now electric or hybrid (phys.org)

AmiMoJo writes: Norway, which already boasts the world's highest number of electric cars per capita, said Monday that electric or hybrid cars represented half of new registrations in the country so far this year. Sales of electric cars accounted for 17.6 percent of new vehicle registrations in January and hybrid cars accounted for 33.8 percent, for a combined 51.4 percent, according to figures from the Road Traffic Information Council (OVF). In February, those proportions fell slightly but remained high at 15.8 percent and 32 percent, respectively. While cars with combustion engines are heavily taxed, electric vehicles are exempt from almost all taxes. Their owners also benefit from numerous advantages such as free access to toll roads, ferries and parking at public car parks, as well as the possibility of driving in bus lanes.

I'd rather not live in a society where they have to try and legislate good manners.

A lot of the people on that freeway have rather hellish lives. They have insane commute times, parking fees, sit in polluted gridlock, shitty jobs, not enough sleep, etc. But you want to force them to spend hours stuck in traffic every week, because their tires will eventually wear out the road by your house, which you want to remain pristine. I can only say that it seems like the lesser of two evils by far, and that courtesy and manners are a two-way street.

Submission + - Will Montana become 3rd state to ditch daylight saving time? (missoulian.com)

turkeydance writes: ok...twice every year Slashdot disses DST...here's 2017's first:

A bill brought by Sen. Ryan Osmundson, R-Buffalo, would eliminate that biannual ritual. He introduced Senate Bill 206 in the Senate State Administration Committee last month, a bill exempting Montana from observance of daylight saving time and keeping the state on “Montana Standard Time” throughout the year.

Similar legislation in several past sessions to exempt Montana from daylight saving time, keep the state on daylight saving time all year, or put the question to the voters failed to advance even out of committee. But SB206 passed committee unanimously and once on the floor, more than twice as many senators voted for it as against it.

But as it is, considering you still need to use the terminal to do something as simple as changing the resolution when the OS doesn't support the GPU drivers, or installing an application...

How to install software. Of course, not everything is going to be in your distro's repository, so sometimes I have to go to a website and download a .deb or .rpm file myself. Haven't compiled anything from source in years.

How to set the resolution.

Submission + - Scientists Have Found a Way to Rapidly Thaw Cryopreserved Tissue Without Damage (sciencealert.com)

schwit1 writes: Researchers have developed a technique that allows them to rapidly thaw cryopreserved human and pig samples without damaging the tissue — a development that could help get rid of organ transplant waiting lists.

Cryopreservation is the ability to preserve tissues at liquid nitrogen temperatures for long periods of time and bring them back without damage, and it's something scientists have been dreaming about achieving with large tissue samples and organs for decades.
