Apache2::Reload reloads modules that change on the disk.
When Perl pulls a file via require, it stores the filename in the global hash %INC. The next time Perl tries to require the same file, it sees the file in %INC and does not reload from disk. This module's handler can be configured to iterate over the modules in %INC and reload those that have changed on disk or only specific modules that have registered themselves with Apache2::Reload. It can also do the check for modified modules, when a special touch-file has been modified.
Systhread is a site about operating systems and programming for real operating system and programming enthusiasts, hobbyists, evangelicals and the like. It is derived from previous sites I have operated and had to (for one reason or another) abandon.
Sajax is an open source tool to make programming websites using the Ajax framework — also known as XMLHTTPRequest or remote scripting — as easy as possible. Sajax makes it easy to call PHP, Perl or Python functions from your webpages via JavaScript without performing a browser refresh. The toolkit does 99% of the work for you so you have no excuse to not use it.
My second favorite language to write programms in.
