greg7mdp··on The shingles vaccine may reduce the risk of dementia
Got the shingrix vaccine for free at my county health center, even though it was not covered by my insurance. Worth checking.
greg7mdp··on Size of Life
The OOM killer strikes again.
greg7mdp··on Libghostty is coming
> 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?

greg7mdp··on The $1.5B Bybit Hack
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.

greg7mdp··on The Miracle of Photography
Nothing really compare to a well made daguerreotype.
greg7mdp··on Sam Bankman-Fried Convicted
Elon Musk says idiotic stuff all the time and people revere him.
greg7mdp··on Free IRS-run tax filing pilot to be available in 13 states
I'm surprised Intuit allowed this to happen. It almost look as if the govt is working for the people.
greg7mdp··on Margaret Cavendish’s brilliant writing was largely neglected in the 1600s
Unless they pretended being a man :-)
greg7mdp··on Datomic is Free

greg7mdp··on Inmos and the Transputer (1998)
Makes me remember how fun it was to read Byte in the 1980s! https://archive.org/details/byte-magazine-1985-05/page/n219/...
greg7mdp··on Bard and new AI features in Search
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.
greg7mdp··on Ask HN: What was being a software developer like about 30 years ago?
There was a lot less googling for sure.
greg7mdp··on Byte Magazine: The Forth Language (1980)
I remember reading this issue cover to cover. Good times. The August issues of Byte were always a treat!
greg7mdp··on Summary After Four Months with Ada
Both are named after Ada Lovelace, mathematician and first computer programmer.
greg7mdp··on Sony's new curved image sensors could shake up the whole camera industry
The writer obviously does not understand the benefit of curved sensors. They will make the lenses cheaper and smaller - they will not change the way photographs look.
greg7mdp··on Mark Zuckerberg says Facebook will turn into a ‘metaverse’
That would be an amazing transformation from a dumpster.
greg7mdp··on The Limits to Blockchain Scalability
Looking forward to the bright future where we rely on centralized exchanges and banks!
greg7mdp··on Crypto crash deepens, stocks slip
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.
greg7mdp··on Crypto crash deepens, stocks slip
Have you heard of DEFI (decentralized finance)?
greg7mdp··on Crypto crash deepens, stocks slip
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.
greg7mdp··on Coinbase from YC to DPO
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.
greg7mdp··on Google’s copying of the Java SE API was fair use [pdf]
Thomas and Alito dissented - these two are always on the wrong side of history.
greg7mdp··on Fastfloat – C++ library 4x faster than strtod
strtod is not a good benchmark. Is it faster than std::format or https://github.com/fmtlib/fmt?
greg7mdp··on DOJ Argues: US can kill own citizens without review when state secrets involved
This is causing outrage because it is US citizens who are killed without review, but I guess it is fine when the US is killing non-citizens, right?
greg7mdp··on Java is better than C++ for high speed trading systems
So not only you have to write the same efficient code you could have written in C++, but on top of that you have to fight with Java features like GC to make sure they don't occur. Sounds like a winning strategy to me.
greg7mdp··on Astonishing Performance of .NET 5
Must have been astonishingly slow in the first place.
greg7mdp··on Writing a book: is it worth it?
Funny coincidence... I just ordered a copy of this book yesterday after reading https://josephg.com/blog/crdts-are-the-future/. I might not be the only one.
