hi all,
i am just starting with PERL and had this doubt related to the speical
operator +.
what it says is that in the line split( / +/,$line);
it will not ignore the initial spaces as it starts a word when it
encounters a space...
so if possibly there is only a single space in the staring,then it
shldnt be a problem isnt it?
and also if there are more than 1 spaces then it says that also the
word count would be 1 more than the total no...

G'day,
I've separated my database calls into a separate dll, and return
results from any database calls as a SqlDataReader (because of SQL
Server use, it's nice and fast). However I'd like to be database
independent by replacing the dll with whatever database is being
supported. This would mean instead of returning SqlDataReaders another
way to return results would have to be used.
Is the best method to return database neutral...

If server 01 running HADR in the primary role crashes, and the DBA does a
HADR takeover by force on the 02 server to switch roles, then the 02 server
is now the primary.
What happens when the Server 01 is brought back up? It still thinks it is
the primary because that was its role when it crashed and it does not know
about the takeover by force command that was issued. Does the 01 server
check the 02 server to see what role they are in...

Hi,
Ours is a windows based application and I have to perform an
action which takes much time (as it requires much CPU time) on a single pc.
I want to split the action to more than two and I want to run the action on
different servers and mix the result at end and do the rest on the result.

I try to follow Steve's paper to build a database, and store a small text
file into SQL Server database and retrieve it later. Only difference between
my table and Steve's table is that I use NTEXT datatype for the file instead
of using IMAGE datatype. I can not use SqlDataReader to read the data. I need
your help, Thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
