Private Virtual Functions

#include

using namespace std;

class A

{

virtual void print1() { cout "1 Aprivate" endl; }

public:

virtual void print2() { cout "2 Apublic" endl; }

class B : public A

{

virtual void print2() { cout << "2 Bprivate" endl; }

public:

virtual void print1() {cout << "1 Bpublic" endl; }

int main(int argv, char* argc[])

{

B b;

a.print2();

b.print1();

A* ab = &b;

ab->print2();

return 0;

}

outputs...

Synclock

"A SyncLock block behaves like a Try...Finally construction in which the Try block acquires an exclusive lock on lockobject and the Finally block releases it. Because of this, the SyncLock block guarantees release of the lock, no matter how you exit the block. This is true even in the case of an unhandled exception." - MSDN

Public Sub Foo()
  Dim sText As String
  Dim objLock As Object = New Object()
  Try
      Monitor.Enter(objLock)
      Try
          sText = "Hello"
      Finally
          Monitor.Exit(objLock)
      End Try
  Catch e As Exception
      MessageBox.Show(e.Message)
  End Try
End Sub

C: Compiling GNU Projects on Windows

I wanted to port the programs I commonly use on Linux to Windows. In particular I have been working on wdiff. A program that compares the differences word by word of two files.

Currently I have been able to successfully compile the program on windows through Cygwin. I also was able to reproduce it on my colleges Redhat server.

The steps I took were:

wget http://ftp.gnu.org/gnu/wdiff/
tar -xzvf wdiff-0.5.tar.gz
cd wdiff-0.5
./configre
make (install) wdiff

However, I would like to run the program natively on Windows similar to the Project: UnixUtils.

I am currently working on a custom port due to the fact that I cannot run ./configure to establish a make file. Suggestions would be greatly appreciated.

Python vs Perl

EXTERIOR: DAGOBAH -- DAY
         With Yoda strapped to his back, Luke climbs up one of
      the many thick vines that grow in the swamp until he
      reaches the Dagobah statistics lab. Panting heavily, he
      continues his exercises -- grepping, installing new
      packages, logging in as root, and writing replacements for
      two-year-old shell scripts in Python.

YODA: Code!  Yes.  A programmer's strength flows from code
    maintainability.  But beware of Perl.  Terse syntax... more
    than one way to do it...  default variables.  The dark side
    of code maintainability are they.  Easily they flow, quick
    to join you when code you write.  If once you start down the
    dark path, forever will it dominate your destiny, consume
    you it will.

LUKE: Is Perl better than Python?

YODA: No... no... no.  Quicker, easier, more seductive.

LUKE: But how will I know why Python is better than Perl?

YODA: You will know.  When your code you try to read six months
    from now.
