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.
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.
You may not believe it's a desert due to irrigation.
The central valley survives on water inputs from outside and can't sustain itself on the available water. That's a desert. Much of the land has subsided by 10 feet or more as ground water has been drawn out, and municipalities are commonly drilling 1000-foot-deep wells to have a hope of their being reliable.
Actually, they didn't start with desert. It was marshland before it was farmed. The largest fresh water lake south of the Great Lakes was in the central valley of Californa. It was sucked dry. The entire central valley was made a desert by the hand of man.
Machines that have broken down will work perfectly when the repairman arrives.
