You can only fit 1-2 graphics cards in a “normal” ATX case (each card takes 2-3 “slots”). If you want 4 cards on one machine, you need a bigger/more expensive motherboard, case, PSU, etc. I haven’t personally seen anyone put 6 cards in

Nvidia’s workstation cards are available with more RAM than the consumer cards, at a lower price than the datacenter cards. RTX 6000 Ada has 48 GB VRAM and retails for $6800, and RTX 5000 Ada has 32 GB VRAM and retails for $4000[1]. Very la

cxx is a huge improvement over manually writing bindings in C (with the inherent limitations imposed by C’s lack of expressiveness). At the same time, you still have to write a cxx::bridge to specify every boundary between Rust and C++ code

My example was a library, so both the library and it’s caller are in the same release artifact (binary/JAR/whatever). If you’re changing the interface of an RPC service, then you can’t do that in a single commit, and need to fall

1. You determine that a library used by a sizable fraction of the code in your entire org has a problem that’s critical to fix (maybe a security issue, or maybe the change could just save millions of dollars in compute resources, etc.), but

For immutable value types, AutoValue[1] is a nice library for automating this. Lombok[2] is also popular, but a lot of orgs avoid it because it has some pretty deep dependencies on implementation details of the JDK that aren't guarante

Bummer that this doesn’t seem to support or explicitly plan for the proposed FUTEX_SWAP operation[1] (unless I’m missing it). [1] https://lwn.net/Articles/824409/

This seems to be a proposal in the early stages of winding through the bureaucracy, and hasn’t been approved by any real policymakers yet. I wouldn’t put too much stock in it at this point.

It’s not standardized, but if you’re using gcc, you can use the cleanup attribute for this: https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attribute... IIRC clang implements it as well, but I wasn’t able to fi

It seems surprising to assert that Nvidia would slash R&D after the acquisition, considering Nvidia’s demonstrated willingness to spend enormous amounts of money on R&D, even for speculative and risky products. For example, they fun

No, by “can be idiomatic”, I meant “is already idiomatic in many codebases”. To name one prominent example among many, LLVM disables exceptions and requires that errors be returned as a value: https://llvm.org/docs/Codi

Result types can be just as idiomatic in C++. The codebase I work in has exceptions disabled and uses absl::Status and absl::StatusOr[1] everywhere. [1] https://abseil.io/docs/cpp/guides/status

The fact that they are using a Neoverse core licensed from ARM seems to imply that there won’t be another generation for NVidia’s Denver/Carmel microarchitectures. Somewhat of a shame, because those microarchitectures were unorthodox i
