I'm trying to design a regular expression that matches (using
preg_match()) when a string is a well-formed Email address.
So far I have this: /^+@+\.{2,4}$/i
I got that from reguar-expressions.info. But PHP keeps complaining of
"Unknown modifier 'Z'".
For the life of me I can't figure out how 'Z' is a modifier.
Can anyone help? Thanks much.

There's all kinds of ways to validate an email address to make sure
it's well formed and whatnot, but what about checking to see if it's a
valid e-mail account?
Like how you can use checkdnsrr() to check to see if a URL is valid.
I know finger used to be used at one time, no? But server block finger
requests, and I'm not sure many e-mail accounts out there are even
fingerable type accounts anyway.
Thanks for any suggestions!

I'm trying to qualify email addresses. Is there any reason why the following
line would not catch an email address beginning with "www." ?
ElseIf Left(Session("em"),4) = "www." Then
I put in a dummy email address: www.mydomain@aol.com and it goes through....
<%=Left(Session("em"),4)%> does reflect "www."
why?
thanks!

In a web based form I am able to make sure that there is text in an input field but I want to force the user into inputting a valid email
address, one that has @ in the address
How can I modify this JavaScript below to enable this ?
if (document.form1.EMAIL.value == ""){
alert("Please complete the E-Mail: field")
document.form1.EMAIL.focus()
validFlag = false
return validFlag

I have a general purpose library that has a lot of checks for bad input
parameters like:
void *
linkedlist_get(struct linkedlist *l, unsigned int idx)
{
if (l == NULL) {
errno = EINVAL;
return NULL;
}

When a function is given a pointer, it is tempting to do an assert on
the pointer to see if it is not NULL. But even if it is not NULL, it
could still be invalid or wrong. What we really want to know is that it
points to memory that we have access to. How about doing this:
void f(int* p)
{
assert(*((char*)p) == *((char*)p);
}

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...

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...
