Hiho,
could somebody please enlighten me about the mechanics of C callbacks to
Python? My domain is more specifically callbacks from the win32 API, but
I'm not sure that's where the problem lies. Here's a description...
I want a callback-based MIDI input/processing, so PortMidi was not an
alternative. I have written a C extension module that links to the mmsys
MIDI API. I separated the win32-dependant code from the Python extension...

I have an application which consists of a main work thread and
multiple threads which each maintain a TCP socket.
When a configuration change occurs, all activity on the socket threads
must be halted. If a socket is no longer in the configuration, that
thread must be aborted and the socket must be closed. After the
configuration is complete, the remaining threads must be resumed.
I currently have the following architecture:

Hello,
I have a class with all static methods that is called by multiple
threads. I was wondering what effect that has on the competing threads.
Does Thread2 have to wait until Thread1 is done with the
StaticClass.Method1 before it can use it?
What if I removed static methods and made all the threads instantiate
its own copy of the class? Would that remove the waiting contention?

In very rare cases a program crashes (hard to reproduce) :
* several threads work on an object tree with dict's etc. in it. Items
are added, deleted, iteration over .keys() ... ). The threads are "good"
in such terms, that this core data structure is changed only by atomic
operations, so that the data structure is always consistent regarding
the application. Only the change-operations on the dicts and lists
itself seem to cause problems...

When I see things in .NET 2.0 like obsoletion of suspend/resume because of
the public reason MS gives of they think people are using them
inappropriately.. use mutex, monitor and other synchronization objects
instead and oh by the way you shouldn't be using them as they can cause
deadlock and other major problems, screams bug or threading architecture
issue and lack of willingness or priority to correct. In reality those API's
are for...

I wrote a access program that works well enough that a handful of
people would like to buy it from me.
My problem is that if I sell it to someone there is no mechanism that
I know of to protect them from giving it to anyone they feel like.
The program produces reports that are specific to a particular
organization but that does stop anyone from just modifying that report
to make it specific to another organization, who they might have...

I've got a number of SNMP devices scattered around the globe that I
want to get some information off..
I've got a couple of classes whcih get a quite complex table together
from SQL and SNMP devices and return a DataTable Object.
but as the devices are all in totally different locations (we have
about 20) and the main time lag is due to latency I want to go and get
the data simultaniuously from all the resources.

Hello Everyone,
I just started learning Threading in C#. I read lot of articles and what I
am trying to accomplish here is
that I have an array of string and I want to pass the member of that array
to each thread one by one until the processing is done.
how can I pass the values one by one to myThreadprocess1 and as soon as one
thread is done with the process,
it should grab another item from array and process that item. How can I

Rather than create a new way of doing things:

why not just pick up ACE into the existing standard:

the same way that the STL (and subsequently BOOST) have been subsumed?
Since it already runs on zillions of platforms, they have obviously worked

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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...

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...
