Performance trick : optimistic vs pessimistic checks
Strings in programming are often represented as arrays of 8-bit words. The string is ASCII if and only if all 8-bit words have their most significant bit unset. In other words, the byte values must be no larger than 127 (or 0x7F in hexadecimal). A decent…

NVIDIA 590 driver drops Pascal and lower support; main packages switch to Open Kernel Modules
With the update to driver version 590, the NVIDIA driver no longer supports Pascal (GTX 10xx) GPUs or older. We will replace the
Impact: Updating the NVIDIA packages on systems with Pascal, Maxwell, or older cards will fail to load the driver, which may result in a broken graphical environment.
Intervention required for Pascal/older users: Users with GTX 10xx series and older cards must switch to the legacy proprietary branch to maintain support:
● Uninstall the official
● Install
Users with Turing (20xx and GTX 1650 series) and newer GPUs will automatically transition to the open kernel modules on upgrade and require no manual intervention.

Multiplying the Shuffle Speed in Go with Batched Shuffling
Programmers often want to randomly shuffle arrays. Evidently, we want to do so as efficiently as possible. Maybe surprisingly, I found that the performance of random shuffling was not limited by memory bandwidth or latency, but rather by computation. Specifically…
