For example, it would take more than 10 feet of concrete to keep a circuit from being zapped by energetic neutrons.

If I was trying to shield against energetic neutrons, concrete is one of the last things I would think of. Instead I'd consider something with a high density of hydrogen like wood, plastic, or even water. The almost equal mass of the proton and neutron allows for a large transfer of momentum from the neutron to the proton during scattering events, allowing the neutrons to be quickly slowed to thermal speeds and greatly increasing the chance they'll absorbed the next time they encounter an atomic nucleus.

Don`t forget Nuclear Missile control systems---

One can wonder where the recent revelation, also in Phys Org, of "clouds" where radiation from outer space is particularly heavy, fits with this. The radiation permeable "clouds" seem a recent development. And one would think that this problem, to one degree or another, would have been noticed long before this, even with larger system elements. One would also think, if this were such a problem, that sensitive systems would have been designed to avoid it. If software failures can cause the same effects, one can wonder why the drop of the plane and "diversion" and the shutting down of air traffic didn't take place before. One can wonder where the requirement that electronics not be used on flights relates to this. In fact, the "diversion" and airport shutdown sound much like dodges airlines use to avoid flying into air denatured by chemtrails so it won't support aircraft, anymore.

Uh, didn't servers used to have parity-checking RAM ??

I think my assessment of very very very unlikely is supported, especially on the ground, when I posted about this in the ionizing radiation cloud thread. Multiple redundancies in avionics systems are pretty good at screening out any danger. But no system is perfect and there can always be a weakspot or vulnerability to this kind of interference, it's just a case of trying to hit a very small target.
Denatured air? What frazzle haired quackery is this? Can you put any SI units to this effect you refer to. Milli mol of delusion per cubic meter perhaps?

@julianpenrod As someone who has been following information about the radiation environment in our atmosphere and space, I suggest that you broaden your sources of information on the subject from just a casual perusal of phys.org articles. You are making erroneous extrapolations. Namely, the effects of space radiation has been known for a long time. At times, a regional power grid has tripped offline due to space weather.

Chemtrails is a hoax.

Yes, but it adds latency to memory access, which is something that gamer's try to avoid.

They mentioned alpha particles. Even energetic ones can't travel more than an inch or two in air, so how would they make it through the atmosphere? I've also seen cellphones bombarded with gamma radiation that would have killed a human, they still worked well, but I supposed some functions might have been compromised, had anyone been using it at the time

It's muons that are produced by cosmic radiation and penetrate deep into the atmosphere and even into the ground. But muons cannot be stopped easily; it would take hundreds of meters of ground to reduce them significantly. Muons can produce other particles though by disintegration and maybe by collisions.

Where can I buy 0.5 MB RAM notebooks?


That's a throwback to times when a 486DX2 laptop running DOS would have 640 kB of main memory, and 4-8 MB of extended memory. Probably somewhere around 1996.

These machines can be still found online for about $20.

Everyone in the field has known about this stuff for decades.

Error correction codes (instead of much simpler error detection codes) are often used when it's effectively impossible for the receiver to ask the sender to retransmit the last message, such as sending instructions to a Mars rover, or real-time situations.

An extremely common situation is where it's actually impossible (as opposed to effectively impossible) to retransmit data simply because the data doesn't exist any more -- during the execution of a program. For example, a variable's value has been overwritten, or the variable, itself, no longer exists because it was local to a subroutine that has returned. The subroutine could be called again, but that variable will most likely have a different value during the subroutine's current call than during the subroutine's previous call.

Virtually all error detection and error correction is done in hardware -- so plan ahead.

Cry havoc and let slip the dogs of minor signal corruption?
