Hello,
I have a problem when reading from stdin (using it as pipe) in a Python program (the sender
is written in C):
C (sender)
write(1, buffer, 4)
Python (recv.py)
sys.stdin.read(256) or sys.stdin.read()

I want to do a very simple thing in Windows. (Using Python Shell.)
I want to write a prompt to sys.stdout and read the user input.
(Ideally, without waiting for a newline.)
Here are the problems I'm encountering. Newbie problems, no doubt.
sys.stdin.read() gives me an attribute error
sys.stdin.readline() doesn't block waiting for input. And even
if it did, it would block waiting for a newline.

Hi,
I want two python programs to communicate over stdIO channels. The one
executes the other via the popen3 function:
amc = Popen3("./amc/amc.py", True, 0)
line = stdin.readline()
amc.tochild.write(line)
amc.tochild.flush()
print amc.fromchild.readlines()

Hi,
I use select() to wait for a file object (stdin) to become readable. In that
situation I wanted to read everything available from stdin and return to
the select statement to wait for more.
However, the file object's read method blocks if the number of bytes is 0 or
negative.
Is there no way to read everything a channel's got currently got without

I have written a program that interacts with a
command line program.
Roughly speaking, it mimics human interaction.
(With more speed and accuracy, less intelligence.)
It works fine under Linux, using select().

Hi,
whenever I try to read input from stdin, the called function (ie.
std::cin.read ()) blocks until my buffer is full. But I want to function
to return immediately, regardless of having read something or not. Is
this possible? Here's the tiny code that blocks:
#include <iostream>
int main ()

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

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...
