After many years of using LISP, I'm taking a class in Java and finding
the two roughly comparable in some ways and very different in other

my 400 Mhz PC while the Java program took 6.5 seconds.
I am running the SUSE 8.2 Linux distribution.
Why is Java that much slower than the C++ program? I read on Slashdot that
Java was almost as fast as C++. ...

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,...
