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:

Greetings.
I want to get everyone's opinion on the use of recursion.
We covered it in class tonight and I want a good solid answer from
people in the "know" on how well recursion is accepted in modern day
applications.
Should we readily use it when we can or only when absolutly forced to
use it?

I'm a college computer science major and I'm studying for my final exam by
going over previous tests. There's one question that I answered correctly
but I cannot, for the life of me, figure out how it works. The machine I'm
currently on does not have any environment or compiler so I can't test it.
The question was to write a recursive function that's passed a char pointer
and returns the maximum valued character in the string. Here's...

Can every problem that has an iterative solution also be expressed in
terms of a recursive solution?
I tried one example, and am in the process of trying out more examples,
increasing their complexity as I go. Here's a simple one I tried out:

So, it appears that Javascript has a recursion limit of about 1000
levels on FF, maybe less/more on other browsers.
Should such deep recursion then generally be avoided in Javascript?
Surprisingly, deep recursion actually isn't that slow for what I'm
doing. Programming this task recursively is so much more
straightforward to me, but currently I'm forced to use an ugly hack to
avoid going over the 1000 level limit. Of course, it could...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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,...

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...
