Comment Re: "Of course it can," says government (Score 1) 75

The comment I was responding to was regarding HAARP. And that's "except" FYI. :-) ECC is actually more reliable, for its problem domain, than a triple voting system. The probability that you would arrive at a valid ECC code for bad data due to multiple bit flips is much lower than than the probability of two out of three systems voting wrong. So, it is at least theoretically possible to design a computer system with data integrity throughout that exceeds that of a voting system.

Faraday cages are really good for RF, and I was writing about HAARP. The X rays that you get from a radiologist don't have the same energy level as cosmic rays. The best we can do about energetic cosmic rays is to make our equipment less susceptible, because you can never have enough shielding.

Comment ECC (Score 3, Insightful) 75

This is why ECC is used to protect memory and data busses. At least on the good stuff :-) . One of the issues is die shrink. As the minimum detail slze of the IC process gets smaller, the potential for radiation to flip a bit gets higher.

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.

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.

You are of course welcome to use whatever you want, as long as you comply with the license. In the case of ProxySQL, that's the GPL. 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.

The high-speed rail was also funded by a state bond measure (which I voted against, back when I still lived there). What it got from fed money I don't know. Regardless, CA is always whining about no money for critical stuff, then spending it wildly on stuff no one needs... not the best way to get my sympathy as a taxpayer.

Per aerial view, it doesn't look like the dam is really in danger -- the washed-out part is a good ways from the dam proper. What might be getting undercut or supersaturated due the breach and suddenly slump is another matter, but assuming it was built from the local rocky ground, probably not a big risk.

Submission + - MariaDB Fixes Business Source License, Releases MaxScale 2.1 (perens.com)

Bruce Perens writes: MariaDB is releasing MaxScale 2.1, a new version of their database routing proxy, and has modified its timed-transition-to-Open-Source Business Source License to make it more acceptable to the Open Source community and more easily usable by other companies. I've blogged the issues I had with the license and how MariaDB has fixed them, and Kaj Arno has blogged the MariaDB side of the story.

Comment It won't work, here's why (Score 1) 400

The plan appears to assume the problem is water transport to the poles. That is, the poles are cold enough but the problem is a lack of water to freeze on the surface.

Yet when there is global warming the first thing that happens is moisture transport increases. More water evaporates into clouds and some of it, more of it, goes to the poles than before.

Thus the long term problem is not a lack of water transport.
