Comment You mean "hard statistics"? (Score 1) 80

"Since 2015, *right-wing extremists have been involved in 267 plots or attacks and 91 fatalities*, the data shows. At the same time, *attacks and plots ascribed to far-left views accounted for 66 incidents leading to 19 deaths.*"

It has only gotten *worse* since then with the right ramping up the violence across the nation dramatically in the last 2 years.

Comment It's because they CAN'T legally be copyrighted (Score 2) 74

Stock image sites make their money by selling licenses to copyrighted images. AI generated art has been specifically ruled by courts to NOT be copyrightable. Which means they would have no legal leverage to enforce their licensing for AI generated artwork.

tl;dr: AI artwork breaks their business model in a way they have no legal remedy for except excluding it from their platforms

Comment Cheap per year, not overall unless you decarbonize (Score 3, Insightful) 177

PREVENTING *all* excess warming by decarbonization would cost a few trillion dollars spread over the next couple of decades and is pretty much finished once you've done that requiring no further 'excess' investment to maintain.

MITIGATING (only) runaway arctic warming by this method would cost at least $11 billion dollars a year - for the next several thousand years (longer than the entire history of 'modern civilization') - costing (order of) 100 trillion dollars net. And requires stable, motivated, and financially capable governments do it that entire time because if you stop you jump from '0' to '100' in less than a decade. I note NO large government in the world has existed for more than a few centuries at this point.

Anyone who ever talked on an encrypted radio channel in the military has experienced exactly this. Never understood why they didn't just mute your own voice in your ear.

You could always tell people who were new to it because they would talk slower and sloower as they unconsciously tried to get their voice in their ear to sync with their speech. After a while you mentally 'switched off' listening to your own voice.

Your "summary" isn't remotely what the updated report says. It says, 50 years after the initial prediction, we are still on track for disaster. Only now instead of it being 70+ years in the future from 1972, it is less than 20 years in the future from 2022.

Submission + - SPAM: Diluting blood plasma rejuvenates tissue, reverses aging in mice.

schwit1 writes:

In 2005, University of California, Berkeley, researchers made the surprising discovery that making conjoined twins out of young and old mice — such that they share blood and organs — can rejuvenate tissues and reverse the signs of aging in the old mice. The finding sparked a flurry of research into whether a youngster’s blood might contain special proteins or molecules that could serve as a “fountain of youth” for mice and humans alike.

But a new study by the same team shows that similar age-reversing effects can be achieved by simply diluting the blood plasma of old mice — no young blood needed.

In the study, the team found that replacing half of the blood plasma of old mice with a mixture of saline and albumin — where the albumin simply replaces protein that was lost when the original blood plasma was removed — has the same or stronger rejuvenation effects on the brain, liver and muscle than pairing with young mice or young blood exchange. Performing the same procedure on young mice had no detrimental effects on their health.

This discovery shifts the dominant model of rejuvenation away from young blood and toward the benefits of removing age-elevated, and potentially harmful, factors in old blood.

Does this mean donating blood helps?

There is a crap-ton of evidence placing quasars at cosmological distances. Arp's idea is one of the DISCARDED ideas about what quasars are for really good reasons.

Starting with - why are there no BLUE shifted quasars? If they are ejected from galaxies, we should should see ones coming at us as well as receding from us.

We have images of gravitationally lensed quasars while necessarily places them FURTHER AWAY than the galaxies acting as lenses. We've even witnessed time delayed changes in the multiple images from those lenses.

We have pictures of some of the galaxies quasars are embedded in - which have the SAME redshift as the associated quasar! Quite the coincidence that, eh?

We can measure adsorption lines in their spectrums from intervening clouds of gas. Again, allowing us to place minimum distances on the quasars since they MUST be further away than the clouds of gas.

We can measure all kinds of properties - and they all agree: Quasars are at cosmological distances.

Technical Q&A QA1779
Reducing Download Size for iOS App Updates

Q: How can I reduce the downloaded size of my app update for users that already have the previous version installed?

A: This document is specific to app updates. See Technical Q&A QA1795: Reducing the size of my App for a collection of techniques to reduce the size of an app when it is downloaded and installed for the first time.

Starting with iOS 6, the app store will automatically produce an update package for all new versions of apps submitted to the store. When generating the update package, the app store compares one or more prior versions of your app to the new version and creates an optimized package for each that contains only the content that has changed between versions of your app, excluding any content that did not change. This comparison looks at everything in the application bundle, including the application executable, nibs, localizations, image files, video files, audio files, text files, and files containing data in a custom format.

Note: The ability to create update packages is not currently available to developers who do not distribute their apps through the app store, such as those distributing enterprise apps.
When used optimally, an update package is significantly smaller to download than the full package of the app and the update will install more quickly. Also, in many cases, this mechanism allows updates to large apps to be downloadable over cellular networks where app downloads are subject to a size limit.

In addition to new content, the update package contains instructions on how to transform the prior version of the app into the new version of the app. New files will be added, modified files will be replaced with their updated counterpart, and deleted files will be removed as part of this transformation. As far as the developer and user are concerned, this process is entirely transparent and the resulting updated app will be indistinguishable from a full download of the corresponding updated version of their app.

To optimize the size of your app updates, you should consider two tips:

Do not make unnecessary modifications to files. Compare the contents of the prior and new versions of your app with diff or another directory comparison tool and verify that you've only changed what you expect within your app bundle.
Content that you expect to change in an update should be stored in separate files from content that you don't expect to change. This reduces the size of the update package and increases its install speed.
For devices running iOS 6.x and iOS 7.0, the update package will include any file, in its entirety, that has changed in the new version of the app. For example, if you have a 10 MB file in your app and only change 1 KB of content within that file in the new version of the app, the update package for that new version will contain the full 10 MB file.

For devices running iOS 7.1 and later, the update package may include only the differences between the old and new versions of a changed file instead of the full file. This may significantly reduce the size of the update package in the case where only a small part of a large file changes, but will increase the update's installation time on the device. For this reason, the two tips above are still important even for updates on iOS 7.1 and later. Minimizing changed content and localizing it to many smaller files instead of one larger monolithic file will reduce the download size in all cases and will speed up installation on devices running iOS 7.1 and later.

Being transgender is not considered a mental illness. Nor is does being diagnosed as transgender result in a 'nearly automatic' diagnosis of schizophrenia. There is an _increased rate_ of schizophrenia among transgender people. But it still remains uncommon - less than 1 to 5% of transgender people are _also_ diagnosed as schizophrenic.

Answers to Your Questions About Transgender People, Gender Identity and Gender Expression from the American Psychological Association

Is being transgender a mental disorder?

A psychological state is considered a mental disorder only if it causes significant distress or disability. Many transgender people do not experience their gender as distressing or disabling, which implies that identifying as transgender does not constitute a mental disorder. For these individuals, the significant problem is finding affordable resources, such as counseling, hormone therapy, medical procedures and the social support necessary to freely express their gender identity and minimize discrimination. Many other obstacles may lead to distress, including a lack of acceptance within society, direct or indirect experiences with discrimination, or assault. These experiences may lead many transgender people to suffer with anxiety, depression or related disorders at higher rates than nontransgender persons.
According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), people who experience intense, persistent gender incongruence can be given the diagnosis of "gender dysphoria." Some contend that the diagnosis inappropriately pathologizes gender noncongruence and should be eliminated. Others argue that it is essential to retain the diagnosis to ensure access to care. The International Classification of Diseases (ICD) is under revision and there may be changes to its current classification of intense persistent gender incongruence as "gender identity disorder."
