This is why ECC is used to protect memory and data busses. At least on the good stuff
Silicon-on-sapphire is the main way to implement silicon-on-insulator, which is more protective of radiation bit flips and less likely to latch-up. But since these have historically been required only for space satellites, they have been horribly expensive. Imagine running an entire IC fabrication just to make a few chips. As there are more applications for rad-hard chips, the price could fall.
Speaking out of curiosity isn't enough. You must speak from knowledge. This is generally achieved through a great deal of work and some experimentation.
It's really obvious when you don't have it.
A view Russian probes got lost while flying over HAARP, I think Phobos Grunt was the most recent one. The theory is that their electronics was grilled by these high-power transmitters. This one actually makes sense though.
This was obfuscation on the part of the Russians. According to the failure report issued by Roscosmos there were other reasons, including use of non-space-qualified components that were susceptible to radiation damage, and insufficient ground testing.

Percona appears to be one person, one René Cannaò, and it looks like he's interested in selling his consulting services. If you are actually making money from using his product, please consider throwing some work his way.
Like I said, Open Source developers should not have to wear hair shirts while their users, sometimes the most profitable companies on Wall Street, rake in the dough.
