I'm working on an app that's processing Usenet messages. I'm making a
connection to my NNTP feed and grabbing the headers for the groups I'm
interested in, saving the info to disk, and doing some post-processing.
I'm finding a few bizarre characters and I'm not sure how to handle them
pythonically.
One of the lines I'm finding this problem with contains:
137050 Cleo and I have an anouncement! "Mlle. =?iso-8859-1?Q?Ana=EFs?="

The interesting patch is the string that reads "=?iso-8859-1?Q?Ana=EFs?=".
An HTML rendering of what this string should look would be "Anaïs ".
What I'm doing now is a brute-force substitution from the version in the
file to the HTML version. That's ugly. What's a better way to translate
that string? Or is my problem that I'm grabbing the headers from the NNTP
server incorrectly?

No, it's not you, those headers are formatted following RFC 2047
<http://www.faqs.org/ftp/rfc/rfc2047.txt>
Python already has support for that format, use the email.header class,
see <http://docs.python.org/lib/module-email.header.ht ml>

Hello out there.
sometimes I need to have proper control of the floating point arithmetic of

C99 standard is quite handy for that purpose. The only problem when dealing
with f.p. exception signals is that there is (afaik) no specification *when*
the f.p. exception is raised, with one notable exception:
'feraiseexcept(int)' raises the exceptions passed in the...

Hello,
We use several user controls and derived custom controls. Some of
which actually hit the database at design time to show data (such as
filling a list box, etc...)
Our c# client server app uses the .NET Isolated storage libraries for
storing connection string and other info about the application. The
problem is that the Isolated storage bombs at design time (when you
try and view a control that hits the database at design time).

After a long week end I am back again. Its nice and refreshing after a short

Today we will discuss about Isolated Storage. This is one of the topics
which I find interesting as I feel that it has a lot of practical usage or
applicability.
We all know that all applications need some storage space to archive certain

Hi,
Are Signal Handling part of ANSI C?
I am not able to find any reference of Sig Handling in Stephen Prata's
"C Primer Plus".
The usage of signals is to trap errors I guess. (It looks similiar to
the concept of try-catch to me.) It seems to relate more to nix OS. Are
signals handling part of Windows too?

Is there anyway to do this without re-reading

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,...
