Well, I wrote my first PHP class today. Yeah!
But to get it to work, in each function within the class I have to
repeat the database connection lines, and that just seems redundant;
there has to be a better way that I'm just not bright enough to think
of.
Any suggestions?
(It's the first 3 lines of each of the two functions below. When I have
it fully written, there will be about 10 similar functions, each
repeating those three lines.)

OK, I may be asking for the impossible, but I'll give it a shot: For a case
like this:
using System.Data.SqlClient;
abstract class Base
{
private SqlConnection DBConnect;
Base(string SqlConnectStr)
{
DBConnect = new SqlConnection(SqlConnectStr);

Hi all,
This may not be the best way to do things I'm not sure... however I have
created a class that handles all the database calls, I didn't want to keep
having to create connections to the database or instances of the same class
so I wanted to make an instance of the class in the top level window form
and be able to access it from the child windows. Is this possible to do? if
so how do you access the instance of the class at the top...

My webserver application (a http handler) accepts a sequence of requests
from client. Each request requires an access to database (password/username
supplied in the request). I am looking at improving the performance of the
webserver. My questions:
1. How should I handle the session as the client will post one request after
antoher (for may be consequtively 5 requests) ?
2. Is there any way to 'cache' the database connection and reuse...

I want to put a live connection in a web page to periodically updated
data. When the data changes, the server notifys the client and gives
the new data. The client does not regularly refresh the page. The
client responds to server-side events only. The screen display changes
without any user interaction.
An application like this might be a chat, stock ticker, or data
inventory.

I am building an app using php and postgresql. My questionis this.
How do you handle people wanting to make parallel changes to a record.
Since in web apps you are doing a select, bring over a record then
updating it, there is no lock on that record while you are making the
changes in your browser window. Does transactions handle that? Do you
make your selection and update all part of the same transaction? This
whole scenario has me...

Introduction
Performance is the main concern to most server application developers. That’s why many of them anticipate using .NET platform to develop high performance server application regardless of the security features it provides.
Microsoft Windows provides a high performance model that uses I/O completion port (IOCP) to process network events. IOCP provides best performance, but difficult to use due to lack of good code samples and...

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...
