  1. "and there wasn't any way of emulating the PS3, or Xbox360 yet" - so what about RPCS3 and Xenia?

  2.  @pierrefley5000  Fair point!

  3. Java is compiled to bytecode than JIT'ed. JavaScript is interpreted and then JIT'ed Python is just interpreted. It can be JIT'ed using PyPy.

  4. It does!

  5. "A JIT executable is not machine code, and it’s not the original script. But it’s been converted to a more optimized code that can be interpreted much faster then traditional" - That's .NET ;-) C# compiles to IL (optimized or not - how you want). Then IL would be JIT'ed at runtime and be optimized even more!

  6. True. But the process of JIT'ing takes a lot of resources. So JIT is more useful on older CPUs but also "warm up" time is longer.

  7. Maybe in Ruby JIT compiler is just bad? So that's not the problem with language itself (most likely).

  8. Thanks!

  9. Not JIT, but some runtime optimizations, as far as I know. PyPy is still WAY faster ;-)

  10. If your program just do one thing and terminates - static compiler ALWAYS would be faster. But if your program is more like a microservice or a game - JIT may make it pretty fast and even faster than static (but NOT faster than static compilation with PGO).

  11. Random information: C# is not dynamically types by default but you could use type "dynamic" and write something like this: dynamic a = 5; a = "five";

  12. Well... Today prices are bigger. But there are pretty well paid jobs too ;-)

  13.  @StephenGillie  Is it well paid? If no - learn something new and try another job ;-) Life is a constant improving, constant moving forward! (actually, I have to remember that too xD)

  14. He mean that any language could be interpreted, compiled or JIT'ed. To make Python compiled instead of interpreted, you should compile it to binary. You couldn't just keep using *.py source files anymore ;-) To do that use Cython to generate a C source file and then compile it using any C compiler. The easiest way to do that is using Nuitka

  15.  @sainansama  In source code or as user input? I thing - second. So, basically, make a program which could do things like: eval(2 + 2) // that's easy! or eval(new String("I like number 2")) // That's harder but C# could generate code in runtime so I think it's not that impossible But your program would be like an interpreter itself ;-)

  16.  @sainansama  Fair point!

  17. And Julia ;-)

  18. Maybe task is not intensive enough?

  19.  @hoagy_ytfc  Agree! Maybe drivers are still bad for little/big cores.

  20.  @vishesh0512  True but as a developer you know what is expected to be there ;-) Name would be a string and age would be an integer. If it's not - there is a problem already, no matter is your types dynamic or not. In most cases xD

  21. But how much time those small team needed to create their first working version? ;-)
