Hello all.
Okay, this seems really stupid, but it's driving me up the wall.
I have a simple script I've written to log some information to a text
file. Everything seems to be okay, the code isn't throwing any errors,
but for some reason it isn't writing to file. If anyone has any ideas,
please let me know.
Here's the code I'm using:

Hi all!
I'm trying to extend the functionality of the file object by creating a
class that derives from file. MyFile class re-implements __init__(),
write(), writelines() and close() to augment the capabilities of file.
All works fine, except for one thing: 'print >> myfile' does not
execute Myfile.write(), it executes the file.write(). If I execute
myfile.write() explicitly, then Myfile.write() is called as expected.

This may be the wrong group but I didn't see anything for VC++ so I'm
trying here.
I have a C++ book by Deitel and Deitel that says I can use fstream
File("data.dat", ios::in | ios::out | ios::binary) to declare a file
object with read/write modes turned on for working with binary data.
I've tried this and my file is not created. The only time it is created
is when I specify ifstream or ofstream but not fstream. I've tried
removing the...

Python Doc Problem Example: gzip
Xah Lee, 20050831
Today i need to use Python to compress/decompress gzip files. Since
i've read the official Python tutorial 8 months ago, have spent 30
minutes with Python 3 times a week since, have 14 years of computing
experience, 8 years in mathematical computing and 4 years in unix admin
and perl, i have quickly found the official doc:

I am pretty much lost here - I am trying to create a managed c++
wrapper for this dll, so that I can use it from c#/vb.net, however, it
does not conform to any standard style of coding I have seen. It is
almost like it is trying to implement it's own COM interfaces...
below is the header, and a link to the dll+code:

FYI - If you are a computer scientist (or geek), this post may be for you.
I wanted to log any search keywords, etc that are used on my site. I created a simple
program that logs search terms into a log file. The problem I experienced was that
I was getting double entries in the log... that is, when writing to the file, each line I
wrote to the file was repeated twice.
How was that possible? Scanning the code provided no clues. The PHP...

I have a problem where some data is being eliminated.
The problem is that the data contains signed numeric fields (the low-order
byte of a negative number uses the first 4 bits as a sign and the last 4
bits as the low-order digit. This produces byte values higher than X'7F'. To
be more specific these values are hexadecimal X'B0' through X'B9'. It
appears the program is eliminating any byte values greater than X'7F', thus
shortening...

I'm using the zipfile library to read a zip file in Windows, and it
seems to be adding too many newlines to extracted files. I've found
that for extracted text-encoded files, removing all instances of '\r'
in the extracted file seems to fix the problem, but I can't find an
easy solution for binary files.
The code I'm using is something like:
from zipfile import Zipfile
z = Zipfile(open('zippedfile.zip'))

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...
