Sadly front end, like “High Level” is a very relative term. For example, in compiler design, the bit that parses code is called the “front end” since the “back end” is what emits machine code. I think that’s what they mean here, the “front end” that understands D3D8 code has been added, presumably there is also a “back end” that converts the parsed/analyzed D3D8 code into valid opcodes for consumption by GPU/CPUs.
In the other direction, a UI/UX is sometimes called a “back end” when it is part of a more complex embedded project where physical controls are the “front end”.
Ada, hands down. Every time I go to learn Rust I’m disappointed by the lack of safety. I get that it’s miles ahead of C++, but that’s not much. I get that it strikes a much better balance than Ada (it’s not too hard to get it to compile) but it still leaves a lot to be desired in terms of safe interfacing. Plus it’s memory model is more complicated than it needs to be (though Ada’s secondary stack takes some getting used to).
I wonder if any other Ada devs have experience with rust and can make a better comparison?
