Someone somewhere or, more likely, quite a few someones are attempting to attack your site or the system on which it is running. Assuming hackers have found your site and are testing it for holes that they might crawl through, let's take a look at how you can uncover evidence of their exploits with a quick examination of your web logs. http://www.itworld.com/tech-amp-society/82470/your-web-site-under-attack#comments Security How-to buffer overflow Perl Sandra Henry-Stocker SQL injection web logs Mon, 26 Oct 2009 19:24:27 -0400 Sandra Henry-Stocker 82470 at http://www.itworld.com http://www.itworld.com/development/74909/peer-pick-perl-scripts-interact-twitter-api "Up until a couple of months ago I had not used a debugger since my FORTRAN days. But I found that it was far easier to develop simple Perl scripts to interact with the Twitter API using a debugger (Komodo) than it was to write a bunch of test scripts." - Ed Borasky http://www.itworld.com/development/74909/peer-pick-perl-scripts-interact-twitter-api#comments Development Open Source Opinion application Perl Twitter Tue, 18 Aug 2009 13:40:32 -0400 ITworld staff 74909 at http://www.itworld.com http://www.itworld.com/open-source/66809/digesting-log-data-part-2 Last week, we looked at a script that digests log files by making clever use of Perl's impressive implementation of arrays. This week, we look at a pared down version of the same script, paying close attention to performance and making some significant efficiency improvements. Though Perl seems to provide us with many ways of accomplishing the same task as does Unix in general, some methods are considerably more efficient than others.  http://www.itworld.com/open-source/66809/digesting-log-data-part-2#comments Open Source How-to Perl Unix Wed, 22 Apr 2009 09:32:01 -0400 ITworld staff 66809 at http://www.itworld.com http://www.itworld.com/open-source/66808/digesting-log-data Reducing voluminous log data to a size that can be read and understood in a matter of minutes can make the difference between systems administrators having the time to review log data on a routine basis and only reviewing it when a problem has become so noticeable that an analysis is unavoidable.  http://www.itworld.com/open-source/66808/digesting-log-data#comments Open Source How-to Perl Unix Wed, 22 Apr 2009 09:26:07 -0400 ITworld staff 66808 at http://www.itworld.com http://www.itworld.com/development/61380/dynamic-languages-not-just-scripting-any-more Because of their potential for high productivity, scripting languages have come to occupy a greater and greater part of the programming landscape, including systems programming and commercial, installable, "shrink-wrapped" products. http://www.itworld.com/development/61380/dynamic-languages-not-just-scripting-any-more#comments Development Feature Perl python Ruby tcl Mon, 26 Jan 2009 10:18:11 -0500 ITworld staff 61380 at http://www.itworld.com http://www.itworld.com/development/59133/z-programming-languages-perl Larry Wall, creator of the Perl programming language, discusses why he developed Perl, the backstory on Perl's multiple backronyms, and the future of Perl. http://www.itworld.com/development/59133/z-programming-languages-perl#comments Development Interview Larry Wall Perl Thu, 11 Dec 2008 10:22:55 -0500 ITworld staff 59133 at http://www.itworld.com http://www.itworld.com/operating-systems/56943/squeezing-out-white-space Ever need to clean up some sloppy text? You can squeeze out extra white space with some very simple Perl commands.

If you're clever enough, you can write your own program. If you're not quite that clever, you can use someone else's program -- like a very cool Perl script I found on the web. http://www.itworld.com/operating-systems/54724/port-forwarding-perl#comments Networking Operating systems How-to Perl port forwarding port-proxy Sandra Henry-Stocker Unix Wed, 10 Sep 2008 06:00:00 -0400 Sandra Henry-Stocker 54724 at http://www.itworld.com http://www.itworld.com/development/54627/state-scripting-universe With the rise of Web 2.0, scripting languages (also called dynamic languages) are now often considered important tools in a developer's arsenal. That's a far cry from than their old reputation as lesser tools for those who can't handle "real" programming. Almost 70 percent of the 1,200 developers surveyed by Evans Data for its most recent Global Development Survey currently use JavaScript. PHP is used by just over a third of developers, and Perl has captured about a quarter of developers http://www.itworld.com/development/54627/state-scripting-universe#comments Development Interview JavaScript Perl PHP scripting languages Tue, 02 Sep 2008 13:42:01 -0400 ITworld staff 54627 at http://www.itworld.com http://www.itworld.com/networking/54428/connection-testing-perl If you've never used the Perl Sockets module for basic connection testing, you might be surprised at how easily you can craft a very useful script.
