Replacing a Spreadsheet
Spreadsheets can be powerful tools, and particularly so in the hands of an expert user. A spreadsheet can be used to reorganize data and to extract information not otherwise available. For example, at a client site, an application report generates a listing of hourly billing, but can't give the cross-reference totals desired.

Transferring Mail to a New Mail Server
Sometimes we just have to move on. Your current mail server may just not be meeting your needs, so you've put up something new. But what about old mail? If your servers are identical (Sendmail to Sendmail, etc.) or use the same mailbox storage format, you may be able to just transfer files directly. If not, read on..

Fork and Exec with Perl
Recently I had a project that required a number of different programs that will mostly run all the time, but need to be restarted now and then with different parameters. Normally, the first thing I think of for a program that runs constantly is inittab or svc (daemontools). The svc facility is the more flexible of the two, and will be what I'll use in the final design, but in the "thinking" stages I played with using a Perl program launcher and controller. What we have is a config file that specifies programs .

Creating Perl Modules for web sites
When you are writing your own code, you are more apt to use someone else's module than write your own, unless your project gets fairly large and complex. Small scripting tasks just don't need the advantages modules offer. However, there is a case where modules might make perfect sense: web server cgi scripts often repeat the same tasks. Putting those common features into a module can make your web scripting easier.
