Hi all, I have hit a serious snag ...
I am writing an app server. I am happy with pythons threading etc however I
am totally confused with handling large request on a socket. For example I
can create a threadingTCPServer, the script that calls the app server might
send a file or an xml request. Where I am stuck is how do you handle large
files ?
for example:

Hi all
I've written a asynchronous socket client class, but i've found that in order to consume it I have to use events, and cannot simply for example
SocketClient client = new SocketClient(110, "some.server.com")
client.Connect()
client.SendData("Hello World")
Instead I have to wait for the async method to raise a Connected event, and call client.SendData from there, for complex chains of operations this because a nightmare chain of...

Hi all,
I've got a server that handles a relatively high number of concurrent
transactions (on the magnitude of 1000's per second). Client
applications establish socket connections with the server. Data is
sent and received over these connections using the asynchronous model.
The server is currently in beta testing. Sporadically over the course
of the day, I'll observe the thread count on the process (via perfmon)
start climbing....

Hi,
I'm suffering a socket race condition - I think. The code works fine at
full speed on a single CPU machine. However when I run full speed on a 2
Zeon machine the socket drops data on an asynchronous receive. If I slow a
connected client down by step debugging or putting Thread.Sleep() calls
between sends then the code works on the Zeon machine.
Below is pseudo code that removes all error checking, try catch, business
logic, and...

Hi
I have 2 operations to perform one is to upload data and the second is
to generate report. Both take huge time(more than 20 mins and I believe
by that time session would have expired) and hence has to be done
asynchronously.
For uploading data, user will click start button and the asynchronous
operation has to start immediately.

Hi,
I have a stored procedure that I want to execute and then wait in a loop
showing a timer whilst it completes and then carry on once I get
notification that it has completed. The main reason for this being to stop
the user thinking the application has frozen when in fact it is just waiting
for a long SP to complete. Another reason for doing it like this is that I
also have had a problem in the past where the SP takes longer than the...

I'm using HttpWebRequest. It seems that all the callback called from
HttpWebRequest are in another thread (not in the "original" thread). Now my
problem is that the "original" thread is the thread that maintains the
interface (the forms). I want to signal from the "worker" thread to the main
thread that I've finished downloading the page. How should I do? I can't
simply wait for the end of the thread as in this...

Hi,
I need to write asynchronous HTTPModule which will sometimes execute long
job. I've written it using AddOnBeginRequestAsync but it still executes
synchronously - I am checking performance counters but after running X
requests which executes this "asynchronous" module all other requests go to
application queue - so it executes synchronously.
Code is based on the following article...

Hi,
I'm trying to implement an asynchronous scheduler for asyncore to call
functions at a later time without blocking the main loop.
The logic behind it consists in:
- adding the scheduled functions into a heapified list
- calling a "scheduler" function at every loop which checks the
scheduled functions due to expire soonest
Note that, by using a heap, the first element of the list is always

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.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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,...

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...
