Howdy,
I currently develop the javascript toolkit qooxdoo
(http://qooxdoo.sourceforge.net), some of you heard it already.
We have discovered a slowdown on Internet Explorers performance when
creating objects with some data and store them in a global object
registry. It take some time to get this example extracted from our
codebase. The attached file (take a look at it please) shows the exact
problem. The time for each object increases...

I've encountered a troublesome inconsistency in the C-language Perl
extension I've written for CPAN (Digest::SHA). The problem involves the
use of a static array within a performance-critical transform function.
When compiling under gcc on my big-endian PowerPC (Mac OS X),
declaring this array as "static" DECREASES the transform throughput by
around 5%. However, declaring it as "static" on gcc/Linux/Intel
INCREASES the throughput by...

In math this expression:
(a < b) && (b < c)
would be described as:
a < b < c
But why is it that in C these two expressions evaluate to something
different for the same values of a, b and c?

In spite of the obvious advantage of not encountering a
NullReferenceException unexpectedly in your running program is there
an offset cost in performance for using String.IsNullOrEmpty() over !=
""? If so, would it be of any great significance if a large number of
strings were being tested over the run of an application?

I have a C# asp.net project in which I create meta keywords
dynamically. I have a problem with "&" character. When the page is
rendered, the "&" character is converted into "&". Is there any
way to stop this?
I already once posted this question and did not get any useful help.
Any help with this issue will be highly appreciated.
Thanks in advance,

char array;
scanf("%19s", &array);
I know this is wrong because it's a type mismatch, where scanf expects
a pointer to char and gets a pointer to an array of 20 char. I know
that question 6.12 of the C FAQ says that it's wrong for that very
reason. What I don't know is where the standard tells me conclusively
that it's wrong. What I also don't know is somewhere that this type
mismatch will break in practice.

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...
