Libghostty is coming 10 months ago

All of this is packaged up into a single zero-dependency C API (it doesn't even rely on libc), allowing it to be easily embedded into any popular language ecosystem.

@mitchellh That's super exciting. I'm wondering how easy it would be to integrate in the debugger frontend I'm working on. Do you already know what the C API will look like?

They didn't sign a transaction for 1 billion dollars. They all signed what they thought was a routine transfer, but in reality what they signed gave the hacker full control of the smart contract (the Gnosis Safe) in which the 1.4B $ of tokens were stored. The hackers, having gained control of the smart contract, proceeded to empty it of funds.

What you should do is sign the transaction on an offline computer (which is booted from a linux OS on a flash drive with only the essential software), simulate the transaction to verify it does what you expect, and then save the signed transaction to a flash drive. Then you can submit your transaction on a connected computer with confidence that you didn't sign your tokens away to someone else.

for exponent 1, 10 and 11 you then have the same

Right. But the exponent is signed as well, so you have the same number of exponent values mapping to values between -1 and 1 (roughly exponent values from -127 to -1) as to all other values (between -inf and -1 and between 1 and inf), exponent values from 1 to 126.

Page and Brin's original crawler had the issue, but they were unable to fix it, and it was Jeff Dean and Sanjay Gupta that rewrote the crawler so that it and the index storage would be hardware fault tolerant.

Most GPUs are used to mine ETH. It is by far the most profitable. Unless another POW coin becomes as valuable as ETH, demand for GPUs will drop precipitously.

Ethereum will solve both issues, removing miners and the energy use by moving to Proof of Stake at the end on this year, and increasing the transaction throughput by 100x factors with level 2 solutions.

I don't see any reason to be skeptical of proof-of-stake. The ethereum beacon network has been up and running fine for months. And POS negates the power usage objection to POW.
