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,
Is the order of initialization guaranteed for static members as it is
for instance members?
Namely, the order they appear the in the declaration?
ie:

Hello,
I need to implement a library containing a hierarchy of classes
together with some binary operations on objects. To fix attention,
let me assume that it is a hierarchy of algebraic matrices with the
addition operation. Thus, I want to have a virtual base class
class Matr;

I want to access an object that is instantiated in the frmMain method from within a static method. When I try to access this object, I get errors that state "Object reference not set to an instance of an object."
I know this is a scope problem, but I don't know how to solve it. My application is a winforms app and I'm instatiating the object from frmMain(). The object is declared:
public static DataAccess myDataAccessor;

I have tried for two days to solve this problem with no luck.
I have a singleton class which has some events declared. When I inherit
from this class the events don't seem to come along with it.
The event in the singleton class always evaluates to null even when I cleary
subscribe to it.
Does anyone have some sample code of how to do this, or is this not possible.

Given a set of intervals {i1, i2, i3, ...} a list is produced; the base
items (0) are placed one at a time into the stream and after the ix one
a interval item (1, 2, 3, etc) of the correct type is created. When
intervals intersect the order is kept (most frequent first).
For example, given the intervals {2, 5, 10} I produce a stream of
objects as follows;
0 0 1 0 0 1 0 2 0 1 0 0 1 0 0 1 2 3 0 0 1 0 0 1 0 2 0 1...

I am implementing a variation on the Singleton design pattern, that
allows up to 8 objects of a class to be instantiated, and returns a
null pointer for anything more than 8.
I am running into a compile problem with GNU g++.
Here is the code:

An interesting/annoying problem.
I created a small example to provoke an exception I keep getting.
Basically I have a C-struct (Container) with a function-pointer in it.
I perform repeated calls to the function in the container. I allocate
(and free in c) arrays to get garbage collection in both C and C#.
After a few seconds I get an exception.
I assume GarbageCollector moves the delegate (or collects is) and when
I don't find it in C...

Hello,
I learned that there are five kinds of static objects, namely
1. global objects
2. object defined in namespace scope
3. object declared static instead classes
4. objects declared static inside functions (i.e. local static
objects)
5. objects declared at file scope.

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....

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...
