I have been thinking about the lazy initialization and double checked
locking problem. This problem is explain in detail here
http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html
I am not fully convinced that this problem cannot be
solved. I am going to propose a solution here. For the sake of
discussion I will post my solution here. It is possible that the
proposed solution does not work, feedback and comments are...

Hi,
I have a simple client-server app, that sits on a serial port and
communicates through that with an attached microcontroller-board. To the
outside, it exposes two sockets (file or inet) which can be connected by
clients to perform certain tasks like uploading programs, giving me a
console and resetting the board. So far, I've used threads - every incoming
connection generates one that will listen to the client socket using...

Hello,
I am writing an application using two event-driven libraries:
wxPython, and twisted. The first problem I encountered in the program
is the confliction between the two all-consuming methods of the two
libraries: app.MainLoop, and reactor.run. Additionally, the fact that
wxPython was to receive requests from the twisted framework as well as
the end user seemed to be simply asking for trouble.
My initial solution was, naturally,...

I'm building an application that makes several user-specified internet
connections; twisted meets my needs more or less perfectly.
I'm running into a problem, however, in that twisted is not allowing
connections (reactor.connectTCP) by hostname, only IP address.
From what I can tell, the problem lies in that Twisted simply isn't
performing the DNS resolutions. From the connection factory's
startedConnecting method, print...

I am creating a class that has a method "Write" that I wish to make threadsafe. The method must block calling threads until the task performed in write is complete. Only 1 thread at a time can perform the task within "Write". 1-10 different threads may call "Write" simultaneously and continuously, some in a greedy manner. That is to say that some of the threads calling "Write" will take all they can get, while other threads may only call...

Hi
First off I'm not using anything from Twisted. I just liked the subject
line :)
The folks of this list have been most helpful before and I'm hoping

Hi,
I have a MDIChild with static properties that can be updated at any time
by the MDIParent. These
properties may also at unknown times be accessed by one or more worker
threads.
Now, I'm not too familiar with threads, but is there a danger that these
properties can get corrupted? MDIParent will only SET the properties while
the worker threads will only GET them. If so how do you lock them and to

Hi all,
I'm trying to write a thread-safe async method to send a message of the form

Hi,
Probably not the best group to post my question but I'm sure there is
some people here that use Twisted.
First here is the beginning of my source code:
from twisted.internet import reactor, defer, threads
import time

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,...

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...
