Very excited to start deploying enterprise SSDs for @indexsupply This one here is 7TB pcie4 kioxia cd6 going into the backup server. Planning to deploy even more powerful pcie5 cm7s to production soon.

FFT and IFFT are fucking wild The elegance of going from value form back to coeff form is out of this world. It must have felt so good to figure that out.

We're going to be changing the name of "Chinese Remainder Theorem" to "Remainder Theorem of America". What a beautiful name.

I'm looking to lease a primo dwelling in SF. Criteria: high quality build in a tranquil location. I've had no luck on CL/Zillow. If anyone has a lead on such a dwelling please do let me know.

Very excited about this for a few reasons 1) My latest PG extension decodes arbitrarily complex ABI data 2) Crypto companies should accept crypto payments 3) @daimo is really good

https://www.phoronix.com/review/amd-epyc-9965-9755-benchmarks/3 Interesting to see the comparison of the 9965 (more cores) and the 9755 (higher freq.) on ClickHouse and RocksDB tests. More cores helps random reads while higher freq. presumably helped all of CH's compression and vectorized query processing. I wonder if the CPUs have different io characteristics.
