Submission + - Supposed Battery Breakthrough. 70% charge in 2mins, 20yr life. (ntu.edu.sg)

chaosdivine69 writes: According to Scientists at Nanyang Technology University (NTU), they have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes and have a 20 yr lifespan (10,000 charges). The impact of this is potentially a game changer for a lot of industries reliant on lithium ion batteries.

In the car industry for example, consumers will save huge on costs for battery replacement and manufacturers will save on material construction since they're using a nanotube structure of Titanium dioxide which is an abundant, cheap and safe material found in soil. Titanium dioxide is commonly used as a food additive or in sunscreen lotions to absorb harmful ultraviolet rays. It is believed that charging an electric car can be achieved in as little as 5 minutes making it comparable to filling up a gasoline based automobile.

I can understand implementing screen locking without device encryption; that's the state my phone currently is in, and it provides exactly the level of protection I require at this point in time - prevents casual snooping or misuse, but does not protect against a dedicated attacker.

Under what situations would device encryption be useful without a screen lock? Your phone data can be read by anyone who gets their hands on it, since the unencrypted data is exposed to anyone who swipes right...

I can't think of any good reason that your screen lock password should be weaker than your device password...

There's a finer distinction at play (which I think you might already have noticed, but are not commenting on):

Currently female users receive X undesirable messages and Y desirable messages, with X much much larger than Y.

Removing photos on a conventional dating site drops both X and Y to near-zero.

The goal is to drop X to zero, while keeping Y as near as possible to the current value.

It is theorised that this is an impossible goal as long as men are doing the messaging, because the creeps will always out-message the sensible guys. ... BUT... this app doesn't attempt to do that. It does what you're suggesting - drop the incoming message numbers for the women to zero, and force them to take the action. The men don't/can't message the women at all. The men have to prove their worthiness by providing suitable pictures and answering daily questions in an interesting manner. The women can then make the first contact.

Passport scan to get a free certificate?

I've been using StartSSL for years, for a number of certificates - all they verify for the free cert is that I can click on a link sent to the postmaster address for the relevant domain...

If you want anything other than basic class-1 certificates for a single hostname there's a cost, and a more involved process; but that process is similar regardless of who does your identity verification.

If you want free class-1 certificates, there is no additional cost, and no super-secret documentation to send around.

I have no experience with StartCom's organisation verification process. However, for domain-verified class-1 certificates for individual hosts, they offer a free, immediate, trouble-free process which involves no more than clicking a link in my email.

Submission + - California Gov Brown Vetoes Bill Requiring Warrants for Drone Surveillance (latimes.com)

schwit1 writes: Brown, a Democrat facing re-election in November, sided with law enforcement and said the legislation simply granted Californians privacy rights that went too far beyond existing guarantees. Sunday's veto comes as the small drones are becoming increasingly popular with business, hobbyists, and law enforcement.

"This bill prohibits law enforcement from using a drone without obtaining a search warrant, except in limited circumstances," the governor said in his veto message(PDF). "There are undoubtedly circumstances where a warrant is appropriate. The bill's exceptions, however, appear to be too narrow and could impose requirements beyond what is required by either the 4th Amendment or the privacy provisions in the California Constitution."

At least 10 other states require the police to get a court warrant to surveil with a drone. Those states include Florida, Idaho, Illinois, Indiana, Iowa, Montana, Oregon, Tennessee, Utah, and Wisconsin.

California's drone bill is not draconian. It includes exceptions for emergency situations, search-and-rescue efforts, traffic first responders, and inspection of wildfires. It allows other public agencies to use drones for other purposes—just not law enforcement.

Submission + - New, large iPhones showing propensity to bend under pressure

Sockatume writes: Apple's new thin-but-wide iPhones 6 require more space in users' pockets. Perhaps more space than is available, as owners are reporting that their phones are subtly but permanently bending after several hours of ordinary sitting, even when stored in a front rather than back pocket. The issue was noted occasionally on the previous aluminium models, the iPhone 5 and 5S; earlier handsets and most competitors' models are made of steel or plastic. Apple commentator John Gruber proffers that affected owners "need looser pants".

Submission + - Data archiving standards need to be future-proofed (enterprisestorageforum.com)

storagedude writes: Imagine in the not-too-distant future, your entire genome is on archival storage and accessed by your doctors for critical medical decisions. You'd want that data to be safe from hackers and data corruption, wouldn't you? Oh, and it would need to be error-free and accessible for about a hundred years too. The problem is, we currently don't have the data integrity, security and format migration standards to ensure that, according to Henry Newman at Enterprise Storage Forum. Newman calls for standards groups to add new features like collision-proof hash to archive interfaces and software.

'It will not be long until your genome is tracked from birth to death. I am sure we do not want to have genome objects hacked or changed via silent corruption, yet this data will need to be kept maybe a hundred or more years through a huge number of technology changes. The big problem with archiving data today is not really the media, though that too is a problem. The big problem is the software that is needed and the standards that do not yet exist to manage and control long-term data,' writes Newman.
