Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

Hi,
I'm having a problem where when trying to open a file in write mode, I
get an IOError stating no such file or directory. I'm calling an
external program which takes an input file and produces an output file
repeatedly, simulating the input file separately for each replicate.
The error occurs when trying to open the input file to write out the
new data. The problem is difficult to reproduce since it only shows up
once every few...

Hi everyone,
I currently have a problem with reading one of my files.
Normally I'd read files like so:
overf = 'C:\\overf'
my_overf = open(overf,'r')
contents = my_overf.readlines()
my_overf.close()
now the file Im trying to read has recently had alot of read/writes from
other users/threads/etc, so every now and again I get a

Alright, I realize this is probably very basic to be posted on this
newsgroup but I cannot figure out what is causing my problem. Here is
the code I am using below:
from getpass import getpass
configfile = file('config.txt', 'w')
serverPassword = configfile.readline()
if serverPassword == '':
print "Server warning: No password has been set!"

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

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
