Comment At least it's good to know FB has priorities (Score 2) 293

They're only permitting the naughty-bits of human bodies in settings "generally recognized as art." It's just so much more dangerous to society to see the image of a female nipple or other male/female naughty-bits than it is to see live-streamed images of graphic violence. (Notwithstanding the fact that we all have those same bits ourselves, simply covered by clothing.)

I'm not advocating anything-goes - I'm not sure what I'm advocating. But I know something is out of balance, here.

Submission + - Android KeyStore Encryption Scheme Broken (threatpost.com)

msm1267 writes: The default implementation for KeyStore, the system in Android designed to store user credentials and cryptographic keys, is broken, researchers say.

In a an academic paper published this week, researchers argue that the particular encryption scheme that KeyStore uses fails to protect the integrity of keys and could be exploited to allow an attacker to modify stored keys through a forgery attack.

KeyStore, which performs key-specific actions through the OpenSSL library, allows Android apps to store and generate their own cryptographic keys. By storing keys in a container, KeyStore makes it more difficult to remove them from the device.

Mohamed Sabt and Jacques Traoré, two researchers with the French telecom Orange Labs, claim the scheme associated with the system is "non-provably secure," and could have "severe consequences."

The two point out in their paper "Breaking Into the KeyStore: A Practical Forgery Attack Against Android KeyStore," that it's the hash-then-encrypt (HtE) authenticated encryption (AE) scheme in cipher block chaining mode (CBC) in KeyStore that fails to guarantee the integrity of keys.

Comment Re:Hillary concerned about legitimacy ? (Score 1) 801

I haven't seen anyone who publishes acting as Hillary's lap dog, lately. Perhaps government functionaries seem to be acting that way, but certainly not anyone who puts anything in the press or online. The only good things I've seen printed about her character have been niche liberal postings, but certainly nothing in mainstream press and nothing in the more visible online.

Submission + - String Theorist Makes Intellectual Property Claim to Suppress Critical Paper (blogspot.com)

An anonymous reader writes: Sabine Hossenfelder at the blog Backreaction has this curious story of a new paper which makes an experimental test of the "multiverse" in string theory: "In a recent paper, William Kinney from the University at Buffalo put to test the multiverse-entanglement with the most recent cosmological data. The brief summary is that not only hasn’t he found any evidence for the entanglement-modification, he has ruled out the formerly proposed model for two general types of inflationary potentials... Much to my puzzlement, his analysis also shows that some of the predictions of the original model (such as the modulation of the power spectrum) weren’t predictions to begin with...To add meat to an unfalsifiable idea that made predictions which weren’t, one of the authors who proposed the entanglement model, Laura Mersini-Houghton, is apparently quite unhappy with Kinney’s results and tries to use an intellectual property claim to get his paper removed from the arXiv. I will resist the temptation to comment on the matter and simply direct you to the Wikipedia entry on the Streisand Effect. Dear Internet, please do your job."

Gee, you've completely missed Russia and China. Of course both of those nations would probably applaud such a move on the part of the US, because it makes pursuing their desires easier.

It's time to remember the classification of encryption as a weapon, and invoke our second amendment rights, "If encryption is outlawed, only outlaws will have encryption."

My impression is that satellites have been using this as part of their attitude control for quite some time. More specifically, they have gyros that they use to change the attitude. Periodically the gyro gets near the limits of what they can do. When that happens, they reset the gyros back to a neutral setting, and offset that with a matching torque against the Earth's magnetic field so the attitude remains constant.

The gyros can move the satellite faster and more easily than the magnetic torquing system, so that's what's used for normal attitude control.

Submission + - LIGO detects another black hole crash, more gravitational waves (sciencemag.org)

sciencehabit writes: The biggest discovery in science this year—the observation of ripples in space-time called gravitational waves—was no fluke. For a second time, physicists working with the two massive detectors in the Laser Interferometer Gravitational-Wave Observatory (LIGO) have detected a pulse of such waves, the LIGO team reported on 15 June at a meeting of the American Astronomical Society in San Diego, California. Once again the waves emanated from the merger of two black holes, the ultraintense gravitational fields left behind when massive stars collapse into infinitesimal points. The new observation suggests that after fine-tuning, LIGO will spot dozens or even hundreds of the otherwise undetectable events each year.

Submission + - Asl Slashdot: How Hard Is It To Have a Smart Home That's Not 'In The Cloud'? 1

An anonymous reader writes: It's beginning to seem like everything related to home (and much other) automation is basically remote control 'in the cloud' feeding information about you to somebody's advertising system. In principle, this should not be the case, but it is in practice. So how hard is it, really, to do 'home automation' without sending all your data to Google, Samsung, or whoever — just keep it to yourself and share only what you want to share? How hard would it be, for instance, to hack a Nest thermostat so it talks to a home server rather than Google? Or is there something already out there that would do the same thing as a Nest but without 'the cloud' as part of the requirement? Yes, a standard programmable thermostat does 90% of what a Nest does, but there are certain things that it won't do like respond to your comings and goings at odd hours, or be remotely switchable to a different mode (VPN to your own server from your phone and deal with it locally, perhaps?). Fundamentally, is there a way to get the convenience and not expose my entire life and home to unknown actors who by definition (read the terms of service) do not have my best interest in mind?

Submission + - Implication of Bayesian reasoning in some mental disorder cases (sciencenews.org)

Taco Cowboy writes: Bayesian theorem describes the probability of an event, based on conditions that might be related to the event, but in specific mental disorders the slightest 'misses' of Bayesian guesses lead into dangerous conclusions after inner amplifying loops

People have assumptions about the world, which are either inborn or learned early in life. For example:
Light comes from above
Noses stick out
Objects move slowly
Background images are uniformly colored
Other people’s gazes are directed at us

From within the dark confines of the skull, the brain builds its own version of reality. By weaving together expectations and information gleaned from the senses, the brain creates a story about the outside world

Guesses just slightly off — like mistaking a smile for a smirk — rarely cause harm. But guessing gone seriously awry may play a part in mental illnesses such as schizophrenia, autism and even anxiety disorders

Experiments guided by Bayesian math reveal that the guessing process differs in people with some disorders

People with schizophrenia, for instance, can have trouble tying together their expectations with what their senses detect. And people with autism and high anxiety don’t flexibly update their expectations about the world, some lab experiments suggest. That missed step can muddy their decision-making abilities

Given the complexity of mental disorders such as schizophrenia and autism, it is no surprise that many theories of how the brain works have fallen short

Current explanations for the disorders are often vague and untestable. Against that frustrating backdrop, great promises are embedded in a strong mathematical theory, one that can be used to make predictions and may actually be able to test them

Bayesian reasoning may be new to the mental illness scene, but the math itself has been around for centuries. First described by the Rev. Thomas Bayes in the 18th century, this computational approach truly embraces history: Evidence based on previous experience, known as a “prior,” is essential to arriving at a good answer, Bayes argued

He may have been surprised to see his math meticulously applied to people with mental illness, but the logic holds

To make a solid guess about what’s happening in the world, the brain must not rely just on current input from occasionally unreliable senses. The brain must also use its knowledge about what has happened before. Merging these two streams of information correctly is at the heart of perceiving the world as accurately as possible

For example, this image — https://www.sciencenews.org/si... — for ordinary people hollow face on the right looks 'protruding', but the same hollow face won't fool those who are infected with schizophrenia

The way the brain combines incoming sensory information with existing knowledge may also be different in autism, some researchers argue. In some cases, people with autism might put excess weight on what their senses take in about the world and rely less on their expectations

Distorted calculations — and the altered versions of the world they create — may also play a role in depression and anxiety, some researchers think. While suffering from depression, people may hold on to distorted priors — believing that good things are out of reach, for instance. And people with high anxiety can have trouble making good choices in a volatile environment, neuroscientist Sonia Bishop of the University of California, Berkeley and colleagues reported in 2015 in Nature Neuroscience

Scientists can’t yet say what causes this difficulty adjusting to a new environment in anxious people and in people with autism. It could be that once some rule is learned (a sequence of computer keys, or the link between a shape and a shock), these two groups struggle to update that prior with newer information

Math may be able to help clarify mental illnesses in a way that existing approaches can’t, by demystifying psychiatric disorders

By treating the brain as a Bayesian number cruncher, it might lead to a more rigorous understanding of mental illness

Scientists hope that a deeper description of mental illnesses may lead to clearer ways to identify a disorder, chart how well treatments work and even improve therapies. Cognitive behavioral therapy could help depressed people recalculate their experiences by putting less weight on negative experiences and perhaps breaking out of cycles of despondence

Beyond these potential interventions, simply explaining to people how their brains are working might ease distress

“If you can give people an explanation that makes sense of some of the experiences they’ve had, that can be a profoundly helpful thing. It destigmatizes the experience”
