I've been working a lot with OpenSceneGraph lately. Overall it is very much
in the spirit of C++. One feature OSG has which is, IMO, an eyesore, is
the presence of a couple of #MACROs to assist in the creation of classes
derived from osg::Object, or osg::Node. The main reason these #MACROS are
useful is because the cpp provides stringification of tokens in the source
file. Here is what the META_Object #MACRO looks like:

I am looking in some old code of someone who's gone. Why should one use
something like namespacename::classname().thefunction()? He repeatedly does
that.
The function is virtual and not static. If you create a temporary
namespacename::classname() class to call thefunction(), at least that is
what I understand of it, then would it not be more sense to make thefunction
static? What the use of making thefunction virtual if you already...

Is it possible to get all href URLs contained in a unordered list and place
them in an array?
Or in fact two different arrays, differently named one for each <ul> group?
<ul>
<li><a href="lemurs.html">Lemurs</a></li>
<li><a href="chameleons.html">Chameleons</a></li>

With the following code I can add a new row to an existing table. That
really works great. Many thanks to all who helped me so far.
But my problem is that the added cells do somehow not have the same style as
the first row which I added by HTML.
I do everything with the JavaScript what I do with HTML except that the
added text with the JavaScript is not
<h5 class = "style_tableentry_middle">Entry middle</h5>
I guess it's only somehow...

Hello,
I have an <ul>, and when i click on a item i want to add a class to
that item. The class itself will change some display properties, using
CSS. See code below.
But, whenever i click on a item, the CSS properties, always applies to
the last item in the list.
How can i achieve this using JavaScript and the DOM?

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,...

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...
