GoPower Plus gives low Hz
I recently bought a GoPower Plus from Walmart. I plugged a Kill A Watt into it and a floor lamp into the Kill A Watt. It said it’s getting 10Hz instead of the standard 60Hz. That’s strange, but it powered the fluorescent floor lamp OK.

Illegal Content and the Blockchain
2021-03-17 Bruce Schneier
Security researchers have recently discovered a botnet with a novel defense against takedowns. Normally, authorities can disable a botnet by taking over its command-and-control server. With nowhere to go for instructions, the botnet is rendered useless. But over the years, botnet designers have come up with ways to make this counterattack harder. Now the content-delivery network Akamai has reported on a new method: a botnet that uses the Bitcoin blockchain ledger. Since the blockchain is globally accessible and hard to take down, the botnet’s operators appear to be safe.
