Re: Generator Inverter Weirdness - Need Advice

Hi, I can't see any other explanation than a horrible amount of switching noise at the generator's output due to poor filtering. That could confuse a frequency meter because there would be many large voltage swings inside each period of the 60 Hz AC voltage. The meter would detect and count all of t...

Re: DNS puzzle. can't access 1 website

Yes, obviously. I can't explain where those old DNS records were stuck for so many days, and why. I suggested using curl, however, you can also use a Firefox extension called LiveHosts for the same purpose. It lets you access a website with a domain name you type in and IP address you type in, ignor...

Re: Rocket lake

Looking at the benchmarks and nothing else, one must think that the 11700K is the 10700K with a couple optimisations and AVX-512. Are there ANY reasons to believe there's a new microarchitecture hiding within, until good guys with X-ray machines and small chainsaws pick the thing apart?

Re: New Bot

We need three more bots or botesses, then we can compile a list of top 5 list-compiling bots. Later on, when the number rises to 5*5 (or 5^5, not sure), it should be possible to compile a list of top 5 lists of top 5 list-compiling bots.

SSDs are doing all kinds of optimization on their own, absolutely. That's SSD makers' secret sauce, and details are not known to anyone else. TRIM is the name of a command that the OS sends to the SSD each time a file is deleted, so it must be supported by both the OS and the SSD. This is the way to...

Probably just another item to add to your list of unsuccesful attempts: try renaming the directory with both "mv" and "rename" commands. "rename" should accept regular expressions in directory names but has to be installed separately on Debian/Ubuntu.
