Firebug – Breakpoint doesn’t hit
If the line numbers aren’t green, it seems like Firebug cannot debug that part of code because it is out of scope. So, if you’re using something like $(function () { … }); Firebug will not be able to access Functions and variables. Does that make sense? Also, is it possible that some other function … Read more

Using __debugbreak() is preferable to directly writing __asm { int 3 } since inline assembly is not permitted when compiling code for the x64 architecture. And for the record, on Linux and Mac, with GCC, I’m using __builtin_trap().

Breakpoint-induced interactive debugging of Python with IPython
The Tracer() still exists in ipython in a different module. You can do the following: from IPython.core.debugger import Tracer def my_function(): x = 5 Tracer()() print 5 Note the additional call parentheses around Tracer edit: For IPython 6 onwards Tracer is deprecated so you should use set_trace() instead: from IPython.core.debugger import set_trace def my_function(): x … Read more
