When IBM and Microsoft partnered on OS/2, IBM got upset when a MS employee rewrote some code to be smaller and more efficient because “negative lines of code!”.
Measure the wrong thing and you’ll get the wrong behavior. Incentives matter.

If you're not familiar with software development, seeing "lines of code produced" as a metric of quality is like paying a cook by the amount of salt they use.
Meta now forcing all employees to use AI tools and tying it to employee performance, according to @theinformation.com.
HR said "this is not an activity tracker—it’s an impact-evidence starter"
That's a fun way to rebrand workplace surveillance.

The problem with saying "just tier to HDD if flash prices are too high" is HDDs are scarce too. HDD manufacturers opted not to invest in expanding fab capacity b/c they'd never recover the capex given declining HDD sales. HDDs are a myopic investment right now.

NVIDIA explains why they used FP8 as a scaling factor in NVFP and not MXFP-style E8M0.
The idea is to preserve the largest value in each block.
