I'm not the OP, but for me it's the absolutely braindead design decisions around arrays, respectively the lack thereof. Arrays (or lists, vectors, sequences, whatever) are such a fundamental concept that not supporting them direct

"Strictly necessary" is too strict a criterion. For me, ls without colors to distinguish between files and directories sucks ass, as would an ls which doesn't sort by name (also not "strictly necessary").

Well, you're 100% wrong: https://godbolt.org/z/en31xx9Yx clang optimizes this function to a single ret , optimizing away not just the memory access, but the call to malloc() as well. I does this (and is allowed

We selected Qt as a cross-platform solution. The C++/Rust interface is the clunkiest and ugliest part of the application, and rather complex because some state is shared between several windows in the GUI and several threads in the bac

For our client, we've developed a desktop application in Rust – with a thin GUI frontend in C++/Qt – to filter, process, and visualize sensor data streams (3D point cloud data from a Lidar). Each data stream was about 400-500 Mbit

That's not a good argument, because it proves too much [1]. You could use the same reasoning to argue against pretty much any transaction: * Don't buy bread, because someone who knows much more about bread (the baker) would mu

I suspect the reason for this is that even great engineers don't scale indefinitely: At some point, if you want to increase output, you have to delegate some part of your work. To increase output even further, you have to delegate even

Don't let Perfect be the enemy of Good. The quality of encapsulation you can achieve in C++ is miles ahead of that of C, even if it isn't all that could ever be.
