In this malformed Coinbase transaction, the mining pool "nicehash" produced a provably unspendable Bitcoin output script due to a bug, and therefore lost most of the entire block reward of 6.25 BTC then worth about $ 123,000.
The output is unspendable because it ends in a constant 0, the disassembly of the first and main output is this series of constants:and for the second smaller one:the third one being an OP_RETURN message.

Amazon anticompetitive acquisition Updated 2025-07-16
Amazon is apparently notorious for having bought off many competitors, many of them just to kill off the competition and clear the way, not to actually reuse them.
youtu.be/tfAhTtBlb2Q?t=849 from Video "Jeff Bezos Revealed by Bloomberg (2015)" clearly shows Tim O'Reilly saying that very clearly about Bezos.Perhaps O'Reilly who is the bookselling business is not the greatest fan of Jeff. But still. My God.
I do know of a number of cases in which he [Bezos] has acquired companies in order to take out competitors, potential future competitors. Rather than because he actually wants that business to continue.
www.yalelawjournal.org/pdf/e.710.Khan.805_zuvfyyeh.pdf Amazon's Antitrust Paradox by Lina M . Khan from The Yale Law Journal raises this incredible issue.
Amazon custom silicon Updated 2025-07-16
Like Google custom silicon, Amazon server operations are so large that with the slowdown of Moore's law, it started being worth it for them to develop custom in-house silicon to serve as a competitive advantage, not to be sold for external companies. Can you imagine the scale required to justify silicon development investment that is not sold externally!

More important than the monk itself in Chinese culture, it is used as a Budhist Amen. TODO find some usage in some Chinese television series.
