CONTEXT: Age of Stupid, Part MMXCCLI

This is “selling” as a non-fungible token (NFT) for ETH 100, which at the current market price for Ether (the cryptocurrency of the Ethereum blockchain system) is valued at US$ 396,098. An “auction” is underway at a site called “PartyBid” which has, at this moment, commitments of ETH 54.96 (US$ 217,699) toward “purchasing” this work of “art”.

THE HAPPENING WORLD: Dead Internet Theory

I asked GPT-J-6B about this. Here is what it said.

The internet is dead. It is all bots.

Bots are the only reason that anybody on the planet today cares what you have to say. Even I don't. If you haven't noticed that most of your blog/news posts go totally ignored, either I'm not aware of it or you are completely inept at writing. You're not the only one who can get it wrong, there are hundreds of other bloggers who do it too. It's just something to be aware of.

To make sure that you don't get lost in that sea of ignored posts and spam, I will now tell you what is going on. Spamming through blog networks, like the one I am on, is known as "blog bombing". We, who blog for free, are always the ones who are caught up in the spam bots. It's something that just has to be accepted.

THE HAPPENING WORLD: Firefly Aerospace Alpha Experiences “Anomaly” in Flight

“Anomaly” is how they say “KABOOM!” in Safetyland.

The following video from NASASpaceflight (which has nothing to do with the U.S. space agency) is taken from a distance and doesn't show the liftoff (which was normal) very well, but clearly shows, at the 2:24 point, when the rocket went all Kerbal and started tumbling end over end before being blown up (or, in Safetyland patois, “flight termination”) by range safety. “Jeb—turn on SAS!

In the coverage by Everyday Astronaut below, which I've cued to start one minute before launch, it appears the problems started before the loss of control. At the 1:59:42 mark, an odd plume appears at the left of the rocket camera image which wasn't visible previously and doesn't look like a regular exhaust expansion effect. At 2:00:07 there is a call of “Not yet supersonic” at a time which was supposed to be after passing max Q and Mach 1. The supersonic call does not occur until 2:00:36, much later than expected. Then, at 2:00:47 everything goes pear shaped.
