I think everyone who used Python will agree that its syntax is
the best thing going for it. It is very readable and easy
for everyone to learn. But, Python does not a have very good
macro capabilities, unfortunately. I'd like to know if it may
be possible to add a powerful macro system to Python, while
keeping its amazing syntax, and if it could be possible to
add Pythonistic syntax to Lisp or Scheme, while keeping all
of the...

Hi All,
First, where can I get some questions of this sort answered?
Preferably, are there good books or online guides that I can consult for
these types of answers when necessary?
1. How do I know, when executing a query from Query Analyzer or
otherwise, how many temporary tables will be needed, and how big they
will be?
2. Where will those temporary tables be created? Always in tempdb?

I have written the following code, to test the concept of storing
objects in a vector. I encounter two run time errors:
1). myClass gets destructed when pushed onto the vector
2). Prog throws a "SEGV" when run (presumably - attempt to delete
deleted memory.
Please take a look and see if you can notice any mistakes I'm making.
Basically, I want to store classes of my objects in a vector. I also
have three further questions:

I would like to add at the beginning of the C tutorial I am writing
a short blurb about what "types" are. I came up with the following text.
Please can you comment?
Did I miss something?
Is there something wrong in there?

Types
A type is a definition for a sequence of storage bits. It gives the
meaning of the data stored in memory. If we say that the object a is an

Hi all,
I am not clear what is the difference between signed and unsigned
in C. Many say, unsigned means only +ve values and 0.
Can I use unsigned int i = -3?
What happens internally ? What conversion happens?
Also on 32 and 64bit machines what happens?
Can anybody explain?

HI -
Sorry for maybe a too simple a question but I googled and also checked my
reference O'Reilly Learning Python
book and I did not find a satisfactory answer.
When I use readlines, what happens if the number of lines is huge? I have
a very big file (4GB) I want to
read in, but I'm sure there must be some limitation to readlines and I'd
like to know how it is handled by python.
I am using it like this:

What happens before main()?
Perhaps someone can explain it succintly and perhaps
someone has a link where it is described? crt0.lib or
something like that comes to mind (surely I have the
source code to that given that I have a number of
compilers (some very old) but I'd rather get some
rough idea first of what's happening there). Is it just
setting up an environment in which the C++ library
will work? What happens from the time a...

Hello,
I understand the default-initialization happens if we don't initialize
an object explicitly. I think for an object of a class type, the
value is determined by the constructor, and for the built-in types,
the value is usually garbage. Is this right?
However, I'm a bit confused about value-initialization, when does it
happen, and what kind of values are assigned to objects?

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...
