I have noticed in the book of words that hasattr works by calling getattr
and raising an exception if no such attribute exists. If I need the value
in any case, am I better off using getattr within a try statement myself, or
is there some clever implementation enhancement which makes this a bad idea?
i.e. should I prefer:
if hasattr(self,"datum"):
datum=getattr("datum")
else:
datum=None

Are there any known applications out there used to test the performance of the .NET garbage collector over a long period of time? Basically I need an application that creates objects, uses them, and then throws them away and then monitors the garbage collection and store statistics on it, preferably in C#. I want to know what is the longest period of time that an application may lock up while garbage collection is processing. Thanks!

In many languages, it is necessary to string together multiple strings
into one string for use over multiple lines of code.
Which one is the most efficient from the interpreters perspective:
Case 1:
str += '<?xml version="1.0" encoding="' + charset + '"?>\n';
str += '<view-source-with version="1.1">\n';
str += ' <default-item-index>' + this.defaultItem +
'</default-item-index>\n';

Hello All:
I have been brought onboard to help on a project that had some
performance problems last year. I have taken some steps to address
the issues in question, but a huge question mark remains.
Last year, all of the tables and reports were stored in Access. The
database was put online so that end users could access the reports
online using Snapshot Viewer. The reports were aggregated on the fly,
and the selection criteria...

Ahmmm. It was my aim to match the performance of C and I achieved that
aim very early on. See, for example "The Design and Evolution of C++".

I have an ASP.NET application which uses a .NET Web Service as a wrapper to
a COM+ DLL.
Performance for a single user is very good. However, I have noticed that
when multiple requests are made simultaneously to the page, it takes (2 x
number of users) longer to serve the page. Interestingly enough, all users
get the page at the same time.
I have traced the routines in the application and the web service, and the
actual getdata...

Hello,
I was just testing VB.Net on Framework.Net 2.0 performance when I run into
the this problem.
This trivial code attached below executed hundreds, if not thousand times
faster in VB 6.0 than in .Net environment, under VS 2005 Beta 2. Does anyone
have any idea whether this will be addressed in the final release?
Thanks,

Hi,
I have a recursive application that walks through a directory structure on a
Hard Drive and writes various file information to a single table in an
Access 2003 database. I am opening a connection to the database at the
start of a worker thread that does all of the work. The connection is
closed when the worker thread completes. I am using a single method to
write a bunch of information to the table.
The application flies...

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
