• Why would Mathematica break normal scoping rules in Module?

  - by Davorak

  As was pointed out in a recent post scoping does not work as expected inside of Module. An example from that thread is: Module[{expr}, expr = 2 z; f[z_] = expr; f[7]] (*2 z$1776*) But the following works as almost as expected. Module[{expr}, expr = 2 z; Set@@{f[z_], expr}; f[7]] (*14*) What language design consideration made wolfram choose this functionality?

• Do we really need high level languages? [closed]

  - by i_love_c

  Seeing the amount of softwares developed (and still being developed) in C and considering the fact that C currently tops the TIOBE chart, I have this one question for you all: Do we really need high level languages like C# or F# or Ruby? Don't you think these so-called high level languages are actually spoiling programmers and resulting in suboptimal and non-efficient softwares?

• huge C file debugging problem

  - by valdo

  Hello all. I have a source file in my project, which has more than 65,536 code lines (112,444 to be exact). I'm using an "sqlite amalgamation", which comes in a single huge source file. I'm using MSVC 2005. The problems arrives during debugging. Everything compiles and links ok. But then when I'm trying to step into a function with the debugger - it shows an incorrect code line. What's interesting is that the difference between the correct line number and the one the debugger shows is exactly 65536. This makes me suspect (almost be sure in) some unsigned short overflow. I also suspect that it's not a bug in the MSVC itself. Perhaps it's the limitation of the debug information format. That is, the debug information format used by MSVC stores the line numbers as 2-byte shorts. Is there anything can be done about this (apart from cutting the huge file into several smaller ones) ?

  - by numerical25

  I was reading that memcpy takes the number of bytes from a source location and adds it to a destination location. Does this mean that memcpy could possibly change datatype entirely ?? memcpy(DoubleOne, CharTwo, strlen(CharTwo)); considering that both values are empty still.

• Why we need to set the variable private / public?

  - by Tattat

  Why don't make all variable private? All the variables must give a getter, setter to modify/read. Why leave the "public" keyword here? Except for convenient, any another reason for that?
