The article is from 2010. C++20 solved the include file issue with modules. The ecosystem is almost there with CMake 3.28 (released) and GCC 14 (some time in H1 this year) providing out of the box support. For most practical purposes, moder

While I agree that there is ongoing enshittification, I do not think it's fair to say we're back at square one yet or any time soon. With Cable I am forced to buy a single ~$70+ plan with 100s of channels I don't need. With t

Not a lot of application software interacts directly with ttys. I think the more relevant example here is stdio, which uses separate fds for reading and writing, like the pipe example.

One really cool thing about ISDN was that it connected almost instantaneously (within a second). In fact I remember the first time I used it, I thought the connection had failed because I could not imagine it connected so fast. This allowed

Rather that adding more fine grained locking, would there have been another way? In particular I wonder of the problem domain of QEmu could have benefited from a thread per core architecture. Do guest OSs try to pin high tps devices to sing

The Python C API has become so verbose that I recommend against using it directly. Recently I mapped a few external libraries using Nanobind, and the result was significantly more concise. Nanobind uses the type system of modern C++ (17 and

Pay scales are ranges not points. You want to be able to reward good performers higher than lesser performers, even in the same level, so that the incentives are aligned. Promotions to a next level are part of this but those only happen eve

Late comment, just saw this. Not sure where the momentum is coming from. The proposal has a new maintainer now, new drafts have been released, and there's a stated goal to get this included in C++26. For me, the appeal for experimental

Yeah I was using the term lockless loosely here, not referring to atomics. I agree that using explicitly switched coroutines is not sufficient for mostly “lockless” programming (but I do think it’s necessary). I was coming from a thread per

> In Python, coroutines cannot yield from within another function call: if coroutine A calls function B, B cannot yield. I know you likely know this, but just for context. This is technically correct of course, B cannot yield, but not ho

A disadvantage of the ‘no function coloring’ in fibers is that it makes lockless programming harder. A nested function call can switch from under you without your knowledge, making it hard to know where the preemption points are and whether

My interest is now piqued.. How does this look on the backend? Does this store Parquet files and if so where? What's the compute model over those files (pyarrow, Spark, Trino)? Most trying to understand how far this will scale.

Why couldn’t they be? Using a Gödel like encoding every program is also a number. So it seems that numbers that are complex enough that they are isomorphic to a copyrightable program should be copyrightable. I tend to think of the neural ne

Not really the way I understand cppfront. While Herb uses modest language when describing his project, my take is that's because it's a huge effort that might fail, but it does not indicate lack of ambition. If anything, I think t
