I'm trying to toy around with PLY (python lex-yacc) by David Beazley
from University of Chicago and realized that the lex module uses python
raw strings. What are python raw strings and how are they different from
regular strings? I've tried to look up in the python documentation but
it just vaguely brushes through by saying that python raw strings are
prefixed with "r" or "R".
In PLY, "+" is "r'\+'" but "-" is "r'-'", why is there an...

I have string that is 2.5 million bytes long.
I tried using Regular Expressions to look for patterns and replace the
pattern found with a pre-defined text. This works great on some computers
but on some others (win 2K server 1gig of ram) it times out!
So I am looking for an alternative method as I've been told Regular
Expressions are expensive.
Here is my pattern;

I'm struggling with something that should be fairly simple. I just don't
know the regext syntax very well, unfortunately.
I'd like to parse words out of what is basically a boolean search string.
It's actually the input string into a Microsoft Index Server search.
The string will consist of words, perhaps enclosed in quotes or parentheses.
I'd like to use Regex to pull out the words, or the phrases if the words are
enclosed in quotes....

I'd like to think that my code* is pretty simple, but I'm running into
memory errors when loading larger documents.
The URL you see below in the first line of the Page_Load function is
about 3 MB. That URL then gets parsed with several regular expressions.
The code often runs out of memory. I'm guessing that each time the
document is parsed, a new string of 3 MB is created -- the several
regular expressions I use consume memory rapidly....

I'm new to RegEx in vb.net so I'm not sure how to do this.
I want to know if a string contains two minus signs "-". If there are two
then I want it to return TRUE.
I also need to know if the string contains two plus signs "+". Should this
be a seperate RegEx or can one RegEx check for both signs?
Thanks!

Hi,
I'm trying to use DataView to find the row number in the datatable that
contains "Rich" in it so that I can highlight it. It works fine when I enter
the entire string (i.e. Richard), but I can't seem to make a search for
"Rich" recognize that Richard is also what I want.
The problem seems to be here:
DataView dv = tCat.DefaultView;
Regex reg = new Regex(@"^Rich");

I download xml logs from several servers every day and read the data out of
them using the XmlTextReader. But about 10% of them each day throw
exceptions because they are not well formed. I don't want to lose the data
in the files that won't load into an XmlDocument. So I was thinking maybe
using a RegEx function, sending a Node Name to the function and having it
return the InnerText.
Is this a good use for RegEx, or is there a better...

Im having some difficulty with strings here, I hope someone is kind
enough to help, I do appreciate it. Im working on a grade point

strings. But I ran into a snag with my getgrades function. The

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....
Now, this would greatly impact the work of software developers. The idea...

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...
