X11 was made in September 1987, long after the 70s. All of the older ways of doing graphics were killed by it due to technical merit.

I find the Xorg X11 server works just fine with HiDPI displays, while Wayland has issues (mainly just zoom). Alan Coopersmith is not on the Wayland bandwagon as far as I know. We might get HDR from the Xorg X11 server one day. Once it is in

I would argue that IBM failed with the BIOS, since they assumed nobody could make a compatible machine without their authorization since they controlled the BIOS and the idea of a clean room reimplementation never dawned on them. It did daw

We should add those planets to the official list too. Gauss considered Ceres to be a planet and I believe him over living astronomers. The motivation for this dwarf planet nonsense was to try to keep the official planet list small so childr

I have met a number of people who will not use the boost libraries. It has been so long that I have long forgotten their reasons. My guess is that it had to do with binary compatibility issues.

C, unlike C++, does not really force new versions onto you, even if dependencies begin using them. That said, Linux switched to C11. Newer versions of C will gradually be adopted, despite the incompatibilities this causes for C++. As for WG

Having worked on performance sensitive code (OpenZFS), I have found less to be more. While C code makes more heavy use of linked lists than C++ code, most of the C code I have helped maintain made even heavier use of balanced binary search

Yet the C++ community is continually trying to get people to stay away from anything involving C. That said, newer C headers using _Generic for example are not usable from C++.

Most C++ code I have seen uses the STL. As for “hyper optimized” data structures, you already have those in C. See the B-Tree code those binary search routine I patched to run faster. Nothing C++ adds improves upon what you can do performan

What will you do when you want to use a 4K monitor? This is not to be dismissive. I am genuinely curious if HiDPI works on motif.

Nice catch. I had goofed by omitting optimization when checking this from an iPad. That said, this brings me to my original reason for checking this, which is to say that it did not use a cmov instruction to eliminate unnecessary branching

That does not show the comparator being inlined since everything was folded into a constant, although I suppose it was. Neat. Edit: It sort of works for the bsearch() standard library function: https://godbolt.org/z/3vE

I have used the preprocessor to avoid this sort of slowdown in the past in a binary search function: https://github.com/openzfs/zfs/commit/677c6f8457943fe5b56d7a... The performance gain comes not from elimina

Try putting objects into two linked lists in C using sys/queue.h and in C++ using the STL. Try sorting the linked lists. You will find C outperforms C++. That is because C’s data structures are intrusive, such that you do not have exte

I doubt that because C++ encourages heavy use of dynamic memory allocations and data structures with external nodes. C encourages intrusive data structures, which eliminates many of the dynamic memory allocations done in C++. You can do int

They also could introduce standards gradually by grandfathering older vehicles into the previous lack of standards, which is what NY did. Newer vehicles subject to the standards can be repaired to stay up to the minimum standard. This large
