Improving Perl Application Performance
A fellow developer and I have been working on a data collection application
primarily written in Perl. The application retrieves measurement files from
a directory, parses the files, performs some statistical calculations and
writes the results to a database. We needed to improve the application's
performance so that it would handle a considerable load while being used in
production.
This paper introduces four performance-tuning steps: identification,
benchmarking, refactoring and verification. These steps are applied to an
existing application to improve its performance. A function is identified as
being a possible performance problem, and a baseline benchmark of that
function is established. Several optimizations are applied iteratively to
the function, and the performance improvements are compared against the
baseline.

Nokia to release Perl for smartphones
Nokia will make an internal version of the Perl scripting language
for Series 60 smartphones available to its developer community, Lee
Epting, Nokia's VP of Developer Relations, tells us. Nokia acknowledges
a demand for more developer options as Nokia's Symbian-based Series
60 platform reaches mass market volumes. |
Right now developers have two choices if they want to be sure an application
will run on a Series 60 device. There's the native Symbian C++ APIs, which
offer lots of power but a steep learning curve, and Java. But even Java is
overkill for simple forms-based applications that are typically knocked up
by business managers, rather than developers; and Java doesn't always offer
access to native resources such as vibrating alert or SMS.

Automating Perl Database Applications
A number of options are available for Perl developers who want to reduce the
amount of work and tedium involved in writing Perl CGI scripts that interact
with a database server. Some of these alternatives include CGI::Application
and Class::DBI with the Template toolkit. However, these solutions may not
be appropriate for every situation. Web sites hosted at an ISP may not
include these Perl modules or allow customers to install these modules
within the Perl directory hierarchy. These solutions still do require some
programming and therefore may not be suitable for entry-level developers.

The State of Perl
A colleague of mine recently asked me about Perl's future. Specifically, he
wondered if we have any tricks up our sleeves to compete against today's two
most popular platforms: .NET and Java. Without a second's hesitation, I
repeated the same answer I've used for years when people ask me if Perl has
a future:
Perl certainly is alive and well. The Perl 6 development team is
working very hard to define the next version of the Perl language.
Another team of developers is working hard on Parrot, the next-
generation runtime engine for Perl 6. Parrot is being designed to
support dynamic languages like Perl 6, but also Python, Ruby and
others. Perl 6 will also support a transparent migration of
existing Perl 5 code.

Nisus Writer Express
According to the company, Nisus Writer Express is for "users who don't want
or need a lot of features that they can't or won't use." It's kind of like
the original Volkswagen Beetle: a solid engine, limited features, and a low
price. In short, Nisus Writer Express is a word processor for people who
want to type, save, and print documents, with no fanfare whatsoever.
This stripped-down product does sport some powerful features. It offers
standard text formatting, support for multiple columns, pagination within
sections, and a real-time word count. Plus, Nisus Writer Express is highly
scriptable, with either PERL or AppleScript -- there are already several
third-party scripts available that add to or enhance the program's features.
That said, scripting isn't likely to be a feature high on your "can't live
without it" list.

| ASP and Oracle |
Does anyone know how to reformat the date so that I can insert a record with .asp into oracle. The format I need is dd-mmm-yyyy . I typically use Dreamweaver to insert data but it doesn't work in this case because of the difference in date format. Any one have some sample asp code that inserts a date field into oracle, or converts the default value of the Date() funtion to the format specified above. ...
