Here are four more mini-mysteries for your amusement
and edification.
In this episode, the program output is not shown.
Your goal is to predict the output and, if anything
mysterious occurs, then explain what happened
(again, in blindingly obvious terms).
There's extra credit for giving a design insight as to
why things are as they are.

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...

When I type the following code in the interactive python shell,
I get 'UTF-8'; but if I put the code into a Python script and
run the script - in the same terminal on my Linux box in which
I opened the python shell before -, I get 'ANSI_X3.4-1968'.
How does that come?
Thanks in advance for your answers! Nuff.

_Essential Mathematics for Games and Interactive Applications_

I just bought it on a lark. After looking it over, I have to say it looks
to be well written. The reason I'm mentioning it here is because it comes
with what looks to be a pretty nice C++ library. The licensing terms for
the CD seem quite reasonable. Basically, you can use the...

The initial CanonMath program presented here
http://canonicalscience.blogspot.com/2006/02/choosing-notationsyntax-for-canonmath.html]
was discussed with several specialists, including father of XML-MAIDEN
project (which provided many interesting ideas over original desing).
The initial CanonMath program (was abandoned) was presented at the w3c
mailing list for mathematics. There was little discussion but
subsequent discussion on others...

Since the idea of encoding mathematics using MathML is being very far
from popular due to a number of factors -expensive tools, bad
accesibility of generated code, unusual verbosity, lack of adequate
support, special fonts, namespaces, special plugins, backward
incompatiblity of MathML with other internet technologies, duplication
of code, and others-, alternative encodings are spreading over the
internet.
Probably the most popular one...

I just upgraded from Python 2.4.2 to Python 2.5.1 and have found some
unexpected behavior that appears to be a bug in the os.stat module.
My OS is Windows XP SP2 + all updates.
I have several programs that have worked flawlessly on all previous Python
versions for years and they are now producing incorrect results in the code
that uses os.stat.
Searching through the 2.5.1 release notes I found the following:

a**b is 1 multiplied by a, b times. 1 multiplied by 0 no times is 1.

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
