And you may have noticed now that your iPhone supports background processing it reboots a lot more often?

Are phones spontaneously rebooting?

dsirijus• 13 years ago

Well, when you stretch a metaphore this far, you have to lie some.

aaronpk• 13 years ago

mine does. usually while doing something like switching active apps when one is using the camera.

alok-g• 13 years ago

Sure. My older Android phone even wiped out data spontaneously (showing a message to me that it is doing so, without choice or warning).

reeses2• 13 years ago

Yes, but the nice thing about iOS 7 is that it reboots much faster.

nmb• 13 years ago

Yup. :(

I thought she meant that the background apps are constantly restarted - which they are.

Without access to spinal fluid or nicely chunked pieces of garbage like molecules

I would be really worried if I started clearing nicely chunked pieces of garbage like things in my sleep.

these two things are not comparable- computers tend to reboot due to 'cosmic rays', cruft left behind by poorly written applications, or, more commonly, nvidia drivers.

my brain goes down to sleep at night to commit and file my memories of the day, for area's to be selectively cleaned, for the brain and body in general to consume less energy and last longer/heal.

I can't hit a reboot button, it's not defrag- it's a complicated required process for living in a human skin.

A simple and compelling reason to meditate is that it can function like a reboot button for your brain. Moreso, in my experience, than sleep.

drzaiusapelord2• 13 years ago

Sorry, but 10-15 minutes of napping is nothing like what meditation can deliver, even at 3 to 5 times the time invested.

Sleep does so many positive things its hard to fully understand how great it is for us.

Anyone: How true is that?

Analogy, not identity.

You're right that brains don't need sleep because of nvidia drivers. But I think you can work a little harder to get the analogy.

reeses2• 13 years ago

Maybe your brain doesn't need sleep because of nvidia drivers, but please do not so easily dismiss those who do.

Some of my dreams would take months of planning, the best modelers/animators in the world, million dollar render farms and even that would pale in comparison. But to play the boring computer analogy, I'd say all brains are on a virtual P2P network sharing centralized cloud storage (various permissions/ownership) and sleep would include customized patches from a master repo.

To be fair it's easier to fake reality when you have root access to the whole brain and don't need to interface through HDMI and GPU.

minor_nitwit• 13 years ago

What makes you think that your brain may not be 'poorly written' for supporting 24 hr+ uptime? Think of the brain has having bad garbage collection or a memory leak, so at some point in time you have too much built up memory that needs to either be dumped or written to disk.

Sleep also plays a part in synaptic conditioning -- it's when the brain prunes itself by separating signal from noise...

"Sleep researchers at the University of Wisconsin-Madison School of Medicine and Public Health believe it is more evidence for their theory of 'synaptic homeostasis.' This is the idea that synapses grow stronger when we're awake as we learn and adapt to an ever-changing the environment, that sleep refreshes the brain by bringing synapses back to a lower level of strength. This is important because larger synapses consume a lot of energy, occupy more space and require more supplies, including the proteins examined in this study."

"Sleep — by allowing synaptic downscaling — saves energy, space and material, and clears away unnecessary 'noise' from the previous day, the researchers believe. The fresh brain is then ready to learn again in the morning" (http://www.sciencedaily.com/releases/2009/04/090402143455.ht...).
