   Good look finding any original STM32 parts at the moment.

   On an M1 Max MacBook Pro the CPU (8P+2E) cores peak at a combined ~240GB/s the rest of the advertised 400GB/s memory bandwidth is only useable by the other bus masters e.g. GPU, NPU, video encoding/decoding etc.

   While I hate unreliable drivers as much as the next guy this is not just an Nvidia problem. Several Linux kernel developers love to break API just to mess with closed source GPU driver e.g. replace an API for no reason other than hiding a f

   Why support real hardware? Old as Alpha AXP CPUs are they are still orders of magnitude faster than emulating the instruction set. Why care about the instruction set? It a very good regression test for the kernel locking primitives and data

   OpenWRT still mostly works with 8MB flash and 32MB RAM, but it works better with twice that.

   It's not that easy. Carbon is largely a subset of the classic MacOS toolkit APIs reimplemented in MacOS X to provide a migration path for existing application to MacOS X. IIRC carbonized applications commonly targeted version going ba

   So clients can read lines from a pipe as stdin.

   According to all benchmarks I've seen the M1 Max doesn't offer significant more memory bandwidth to the CPU cores unless (unless the GPU is busy as well). You have run a microbenchmark all all P and E cores to reach the internal b

    ~98% of the ASN.1 parsing bugs could have been prevented by generating the parser instead of handwriting yet another recursive descent parser "with a few clever optimisations".

    I'm sure the log4j developers have just as much potential as the code they're sort of maintaining. If you let them into your codebase you get federated remote code updates for free .

    While I haven no personal experience writing aarch64 assembler code my experience with ARM v6m an v7m makes me doubt your implied insult that ARM just failed/didn't give a fuck about their instruction set. Thumb 1 and 2 are well d

    Now compare how many different versions of the functions are required for the dozens of possible x86 extensions (and combinations of them) and all the prologue/epilogue code required to watch out for page boundaries and unaligned point

    You have widening operations e.g. 16x16->32 bit multiplications and can reduce number of available registers to get longer vectors, but among the really interesting ones are fault only first load and masked instructions that enable the v

    There are lots of good reasons to make cryptographic operations instructions instead of a memory mapped peripheral, but I prefer something like VIA padlock which implemented cipher modes instead of just implementing the round function as in

    Which at least back in the day neither the IBM compilers nor GCC 2.x - 4.x made much use of. I've seen only a few handoptimzed assembler routines get decent use out of them. Easy to fuse pairs a probably a good compromise for carry cal

    IIRC few Power(PC) cores really split the condition register nibbles into 8 renamable registers and while Power(PC) includes everything (including at least two spare kitchen sinks) only a few instructions can pick which condition register

    This wasn't about how the SATA controller talks to the drives, but about how the SATA controller is presented to the operating system. The IDE/legacy setting was useful at the time because Window XP lacked AHCI drives on the insta

    First of all: thank you for taking the time to respond to the irate crowd. Second: It's still a really bad idea, because it feeds into the narrative that inherently unsafe client side restrictions are a viable security barrier e.g. dan

    But on VNET enabled kernels (enabled in GENERIC since 13.0) you can have multiple instances of the IP stack to provide jails with their own IP stacks including a loopback, firewall(s) and IPsec.
