I was trying to troubleshoot a login page that doesn't work - it keeps
saying the login/password is missing - when my tracing discovered this
peculiar behavior.
register_globals is off, so at the top of my script I assign a few
variables to incoming GET and POST values.
$login = clean($_POST, 30);
$passwd = clean($_POST, 30);

This is a comment aside the empty class behavior FAQ.
I understand there are a fair number of reasons which make empty
classes have non-zero size (except as base classes). If ``class foo''
were of size 0, then:
- an object of type foo may lie at the same address as another.
- arrays of foo objects would have size 0, and pointer arithmetic on
array cell would break.
- requirements of the standard explicitly stating objects have

Problem:
I have a vector full of two different derived class objects (class B
and class C) that are derived from the same base class A. I want to
loop through vector and invoke a member function in only objects of
class B and skip over the objects of class C. To complicate things,
I'm using the vector position (index) as an argument in the invoked
member function. It is possible to move the position into the object
by adding a data...

So, Python 2.5 will have new any() and all() functions.
http://www.python.org/dev/peps/pep-0356/
any(seq) returns True if any value in seq evaluates true, False otherwise.
all(seq) returns True if all values in seq evaluate true, False otherwise.
I have a question: what should these functions return when seq is an empty
list?

I'm stumped here. I run the procedure Batch_Select against the database
with @ID=18 and I get the expected data.
When it loads into a SqlDataReader, it gets messed up somehow.
Initially, after the reader.Read(), it has a row with 13 data columns,
but they're all empty. So, my GetInt() function throws an error. When
it jumps to the catch(), reader's columns then show the proper data.
What gives?
I have reader._data (which is the ID...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
