In the context of LATEX, some Pythonista asked what the big
successes of Lisp were. I think there were at least three *big*
successes.
a. orbitz.com web site uses Lisp for algorithms, etc.
b. Yahoo store was originally written in Lisp.
c. Emacs
The issues with these will probably come up, so I might as well
mention them myself (which will also make this a more balanced

I'm trying to create Python parser/interpreter using ANTLR.
Reading grammar from language refference I found:
or_expr::= xor_expr | or_expr "|" xor_expr
For me it looks like infinite recursion. And so it says ANTLR. Maybe I
don't understand EBNF notation. For me it should look like this.
or_expr::= xor_expr | xor_expr "|" xor_expr
and in ANTLR grammar file like this:

getting a bit confused with the details of how c's grammar is
specified, especially when you get self-reference like in this:
postfix-expression:
primary-expression
postfix-expression
postfix-expression ( argument-expression-listopt )
postfix-expression . identifier
postfix-expression -> identifier

Hello,
I have a question about the correctness of the language grammar for the C#
2.0 specification. I am working with the grammar specified in the June 2005
ECMA-334 standard.
Basically, a using-namespace-directive is defined as follows:

Hello... I'm using the grammar at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csspec/html/vclrfcsharpspec_c.asp
as a reference in creating my own C# parser using a custom framework.
(Please let me know if there's a better group to post in.)
Some questions:
(1) Is this grammar specification known to be complete and correct?
(2) Is there a normalized LL grammar available already suited for

There are many other words that could fill in the blank though.

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

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....

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...
