If you want your code to be bulletproof, do you have to explicitly check
for the existence of any possibly-undefined variable?
Example: window.outerHeight is defined by some browsers, but not others.
It would therefore seem prudent, before using this variable, to do
something like:
if (typeof (window.outerHeight) != "undefined") { do stuff that
refers to this variable }
else { work around the fact that the variable isn't defined }

I am contemplating getting into Python, which is used by engineers I
admire - google and Bram Cohen, but was horrified to read
"no variable or argument declarations are necessary."
Surely that means that if I misspell a variable name, my program will
mysteriously fail to work with no error message.
If you don't declare variables, you can inadvertently re-use an
variable used in an enclosing context when you don't intend to, or

Let it be mentioned that Javascript is not my forte, so the solution to
this could very well be a simple one.
I am working on an AJAX function where I can pass a URL and the target
ID in, and have the function update the target ID with the URL. There
is a bit more to it then that, but that is the basics.
my difficulty comes when I try to assign a variable to:
"document.getElementById('-> var gose here <-').innerHTML"

Iam wondering what the benefit of using const over static readonly is.
static readonly is a runtime constant and can be set once in the initializer
or the static ctor, whereas const is suffering from binary incompatibility
since it is hardbaked into the binary.
I do not believe there is a performance advantage with using const over
static readonly since the JIT will take account of that or am I wrong here?

Hi,
I'm not sure where to post this - but I'll try here. I'm encountering
some really weird behaviour in visual studio and I can't work out where it
is coming from.
In various files, seemingly at random, the compiler seems to "forget" about
references declared in the code behind file. So when I build I get a whole
string of errors like "dgdSearchResults is not defined", but if I right
click -> goto definition it goes straight to the...

I have written a method that should modify the folder path passed to it into one that exists and is selected by the user. It then returns a boolean depending on whether a folder path was selected by the user
It then dawned on me that I was passing in a readonly property into the method yet neither at compile time or runtime was I getting any kind of error or warning.
I tested with a simple string field and it alter the string as expected but...

Hi.
This is my first post, though I've "lurked" for a while because I find these forums very helpful.
Ok my problem is the following. I have a class that contains a "MakeByteArray" function.
I have many objects of that class. Inside that function, I have a private variable,
that is NOT static. It seems that when I put all these objects in...

It is possible to declare and use/instantiate a class with a
uninitialized readonly field without even a compiler warning. Why don't
I get warnings?

By definition, readonly fields can only be initialized inside a

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...

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...
