I have a number of strings, containing wildcards (e.g. 'abc#e#' where #
is anything), which I want to match with a test string (e.g 'abcdef').
What would be the best way for me to store my strings so lookup is as
fast as possible?

Hi all
Does anyone know of a fast way to calculate checksums for a large file.
I need a way to generate ETag keys for a webserver, the ETag of large
files are not realy nececary, but it would be nice if I could do it. I'm
using the python hash function on the dynamic generated strings (like in
page content) but on things like images I use the shutil's
copyfileobject function and the hash of a fileobject's hash are it's

Microsoft, in one of its "Help & Support" pages on ADO, says that a
System DSN is three times faster than a File DSN. I find that a bit odd
for the simple reason that won't it be faster for a script to access a
file to get info about the database source than access the same info
from the registry which will be the case if a System DSN is used
instead of a File DSN?
I very well know that ultimately a DSN-less connection is the best!

I'm writing a c++ program that has many (100+) threads read/write files
simultaneously. It works well if not considering the efficiency. The
file i/o seems to be the bottleneck.
This is my code to read from and write to files:
#include <fstream>
#include <sstream>
#include <string>

In "Learning Standard C++ as a New Language" Bjarne Stroustrup claims that
properly written C++ outperforms C code. I will just copy his first example
here, which is supposed to demonstrate how C++ abstractions do not only make
code easier to understand but also make it more efficient:

The simplest specific example I can think of is a program to find the mean
and median of a sequence of double precision floating-point numbers read...

Has anyone have any ideas for a possibly more efficient approach to
conditionally executing code based on bits being set (to zero)?
example attempt: If the particular bit is set to 0, do something (in
this case increment a particular output)
void foo(int input,int* output)
{
if( !(input & 1) )

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,...
