When rewinding to an earlier turn, what if that turn is more than 1hr old? Can this cause KV-cache misses compared to continuing the conversation?

I used to switch coated (teflon, ceramic, other fancy gadgets) pans every 1-2 years after eventually wearing them out. This seems so wasteful! I wish somebody had given me the following advice earlier: get 1-2 good uncoated steel pans. They

I am running the trial and it seems great except for two crucial deviations from Dock behavior. Clicking on a button ("chip") does not bring the associated window to the foreground. It does work when I hover over a chip and then

I am very worried by feature creep in libc++ and libstdc++ and the harm that this inflicts on the wider C++ ecosystem. Transitive inclusion of large parts of the STL, and entangling of STL with core language features are both extremely bad.

> Why would you recommend that? [..] It's a bunch of work for no benefit. nanobind/pybind11 (co-)author here. The space of python bindings is extremely diverse and on the whole probably looks very different from your use case.

There is also IINA that somehow seems more snappy/better-integrated on macOS.

Caution: if you rely on pybind11 or a project using pybind11 (many projects do, like NumPy/SciPy/Tensorflow/PyTorch..), hold off on upgrading to Python 3.9.0 for now. A change in Python 3.9.0 introduces undefined behavior in

What's wrong with red-black trees? :) Since you mention C++: you do realize that std::map will typically be implemented with one?

The extra-painful part about this whole situation is that it's apparently only due to Apple blocking NVIDIA from signing and publishing their drivers. (for whatever bizarre reason they may have to do that)

Lack of NVIDIA support is a deal-breaker. The AMD ecosystem is just so far behind when it comes to frameworks like CUDA, OptiX, cuDNN, etc.. Why can't Apple open up kernel-level support by cooperating more with NVIDIA? This state of th

Thanks! We'd love to have a new print edition at some point in the future, but the details of this are yet to be determined.

This analysis is somewhat dated and leaves out one important fact: nowadays, floating point arithmetic is carried out using a set of special scalar SSE instructions (and not the ancient x87 co-processor, as was done in the author's ben

Not quite -- while pybind11 was originally inspired by boost::python, it is an entirely different project that is intended to address many of its problems.
