It's not just whole cells that can be scavenged, but also old organelles within each cell. You only need around 50 grams of protein on a normal day. During times of famine, construction of new cells is slowed down to minimal maintenance, so protein requirements are lower. There's about 10 kg of total protein in a human body, so even if just 1% (wild ass guess) of that is kept in the form of senescent cells and organelles, it should provide enough material to last a couple of extra days without impacting physical performance. In nature, that could be difference between life and death.
It could be that the body simply leaves them around in times of plenty, just waiting for the inevitable winter time when we would run out of food, and then break down the senescent cells to scavenge them for proteins. Our body doesn't have a dedicated protein store, like it does for fat and carbs. There is a lot of protein stored in the muscle, but breaking down muscle in times of hardship will be detrimental to your abilities to find the scarce food. Having some extra junker cells around could be an evolved strategy to improve the odds a little.
If you want to get rid of your senescent cells, you should mimic that process by regular fasting. I plan to do a 5 day fast this winter.
Theatre is not known as being a hot spot for tech entrepreneurs, nor profit generation.
Obviously not, but I wasn't talking about the theater, but about company providing the solution. For them, a complicated system with electronic glasses is much better than simple mirrors.
Also, brains are only superficially alike in structure. Fine details differ from person to person, so you can't just copy a thought from one brain to another. The only way to do this is to set up a communication channel, and then the two brains practice to convert their thoughts into a mutually agreed upon signalling system and back.
A few comments back I was saying that we already have this, and it's called "talking". It got moderated funny, but I was actually serious.
I can't find any reference for that. Are you sure you're not thinking of QNX ?
Either way, it's not impossible to use a real time OS for desktop use. It's just not very practical. A real time OS is usually slower, and less feature-rich, because it is required to be completely predictable in its worst case timing.
First of all, people shoot videos of any random thing, and there was a room full of people. Secondly, you don't have be filming the painting. You could have a phone in your hand, and then start recording as soon as you see it happening. Thirdly, someone knew it was going to happen.
Also, triple redundancy only helps to protect against SEE (Single Event Effects), those are cases where an ionizing particles changes some charge, and flips a bit in the memory. These are recoverable errors. The processor can reset the faulty bit, and continue normally.
The problem is that part of the cosmic radiation consists of heavy element nuclei, flying at near speed of light. These don't just flip some bits, they have enough energy to permanently dislocate atoms in the crystal silicon lattice. Due to this damage, the processor will get higher leakage currents, and will eventually stop working altogether as the damage accumulates.
Shielding is impractical, because a thin layer of metal (good enough to block gamma radiation), can't stop these highly energetic particles. Even if the particle hits the shielding, it doesn't stop it, instead you get a shower of secondary particles, still strong enough to cause damage. Radiation hardened processors use a different technology that is less sensitive to damage (at the cost of lower logic density)
I already posted with arguments and links and I don't want to repeat myself but the rover has many gigabytes of memory.
How is having gigabytes of flash relevant for the amount of DRAM ? These have different purposes. You have not posted a single argument about the RAM requirements.
Most military applications deal with the same radiation environment as consumer electronics, so I wouldn't expect them to be hardened against cosmic radiation.

Zeppelins are truly a majestic form of transportation, until you try to land one in a storm.
Layered Frickin' Roadways!

But how is your solution going to provide us with huge profits ?
The James Randi prize is no longer on offer, unfortunately.
The stuff that came out of the bottom looked like paper, not canvas.

Talking to my wife gives me little insight into what she is actually thinking.
Adding a different communication channel is not likely to be helpful if the thinking process itself is incompatible.
It's called talking. We've been doing it for a long time.
That makes it even more amazing that video doesn't start until half of the artwork is hanging out.
I can't find any reference for that. Are you sure you're not thinking of QNX ?

Just take the core out of a regular shredder, and add some batteries.
First of all, people shoot videos of any random thing, and there was a room full of people. Secondly, you don't have be filming the painting. You could have a phone in your hand, and then start recording as soon as you see it happening. Thirdly, someone knew it was going to happen.
No you need to be original. You can't just copy someone else's disdain.
What I find amazing is that there doesn't seem to be a video showing actual shredding. Just the aftermath.
That's a tiny Cortex M0 with only 32 kB RAM and only 128 kB program memory. Doesn't really compare to the Power PC CPU that's used in the rover.
VxWorks is a real time OS, that's not what you want in a consumer OS.
The MMRTG isn't running out of power. The problem was that the Li-Ion batteries were getting drained by the computer using too much.
I believe they already have done a good job at it.
So they must have had good reasons to put 256MB of DRAM on there.

Here's an application that requires images to be loaded into the computer's RAM:
