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

I have a loop that is set to run as long as the arraylist is > 0.
at the beginning of this loop I grab the first object and then
remove it. I then go into another loop that checks to see if there
are more objects that match the first object that i grabbed. If
they match then I put them in an array. I would like to remove each
match from the arraylist as I find them to speed things up and so
that they don't get checked again. If I try...

Recently, a heated debate started because of poor mr heathfield
was unable to compile a program with // comments.
Here is a utility for him, so that he can (at last) compile my
programs :-)
More seriously, this code takes 560 bytes. Amazing isn't it? C is very
ompact, you can do great things in a few bytes.
Obviously I have avoided here, in consideration for his pedantic

Hi all,
I would like to remove the oldest rows beyond a predefined size from a
DataTable. Is it possible to remove a bulk of rows in one shot or do I have
to loop and do a DataTable.Rows.RomoveAt(0)

I have created a program which creates and renames files. I have
described everything in comments. All I have is the
cod-duplication. function like fopen, sprint and fwrite are being called
again and again.
I know to remove code-duplication I have to make functions and pass
arguments to them but I am not able to think of a way doing it. Can you
post some example for me, out of this code:

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...

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...
