- Re: Happy tickets benchmark2
Not at all, any series against MIN delivers the best value for MIN(result) not for runtime! Ex. Prog 1 Run 1: 130 = 100 + 30 Run 2: 160 = 100 + 60 Run 3: 170 = 100 + 70…

It's a wrong choice. As we can see and reproduce, at least C# or other Pascal-like environments (Oxygene) are significantly faster.…
- Re: Happy tickets benchmark2
As I said, the goal of the test is to compare the compilers, not the programmer's intelligence. You should remove inner loop from C and C# code to get a meaningful…

In TPersistent, we have two virtual methods. Assign() which calls AssignTo(). 1) Why are they both virtual? It seems like Assign() is what I call a template method,…

I see, and it is what I said many times: you wrap the if-statement into pseudo-function. This make no sense and will be source of programmer's errors. The simplest case…

Holy sh*t, ça continue ! :) Even if evaluation order will be assured and well documented, it doesn't make sense! Example : x := iif(Obj = nil, 0, Obj.Value); // Seems…
