Correct configuration of the MinSpareServers, MaxSpareServers, StartServers, MaxClients, and MaxRequestsPerChild parameters is very important. There are no defaults. If they are too low, then you will underutilize the system’s capabilities. If they are too high, then chances are that…
Parrot Objects (noun, not verb) Piers Cawley worried about class private attributes and asked it it was still going to be possible to write an object serializing tool that wouldn’t require tons of Perl class overloads. Dan said that…
Disclaimer: As you know, each month I try to review a recently published Perl book, and I aim to cover all the majors as they come out. The book that’s fallen onto my desk for review this month is…
Welcome to the first Perl 6 summary of the new ‘Copious Free Time enabled’ era, which should mean that these summaries will get mailed out on Monday evening from now on. We start, as usual, with perl6-internals The eval…
Screen-scraping is the process of emulating an interaction with a Web site - not just downloading pages, but filling out forms, navigating around the site, and dealing with the HTML received as a result. As well as for traditional…
Summary time again, damn but those tuits are hard to round up. Guess, what? perl6-internals comes first. 141 messages this week versus the language list’s 143. Objects (again) Objects were still very much on everyone’s mind as the discussions of…
It’s been nearly six months since the release of Perl 5.8.0, but many people still haven’t upgraded to it. We’ll take a look at some of the new features it provides and describe why you should investigate them yourself….
… And we’re back. Yup, it’s summary time again. We’ll dive straight in with perl6-internals (as if you expected anything else). More Thoughts on DOD Leopold Tötsch posted a test program showing the effects of PMC size and timing…
Hello, and welcome to the first summary of 2003; welcome to the future. This summary covers two weeks, but they’ve been quiet what with Christmas and the New Year’s. So, starting as usual with perl6-internals A Pile of Patches to…
It’s desirable to avoid forking under mod_perl, as when you do, you are forking the entire Apache server - lock, stock and barrel. Not only is your Perl code and Perl interpreter being duplicated, but so is mod_ssl, mod_rewrite,…
You know, it’s not easy having the happiness of billions of children around the world resting with your organization, and it’s even harder on the IT department. The incorporated elves and pixiefolk of the North Pole, under the direction…
Dave Rolsky and Ken Williams are the authors of Embedding Perl in HTML with Mason. Mason is a powerful framework for generating dynamic text, and is especially useful when creating complex, featureful Web sites. For those (hopefully few) folks…
Another Monday evening. Another summary to write. Starting, as is becoming tediously predictable, with perl6-internals. Another JIT Discussion Toward the end of the previous week, Leopold Tötsch posted something about the latest round of changes to the JIT core….
Sharing Memory As we have learned in the previous article, sharing memory helps us save memory with mod_perl, giving us a huge speed increase; but we pay the price with a big memory footprint. I presented a few techniques to…

And some rough beast, its hour come ‘round at last slouches toward… And then the scansion goes to pot and I can’t make a joke fit. Shame. Anyhoo, it’s time for another episode of the continuing saga of Perl…
"Oh! my ears and whiskers, I’m late!" It’s 0650, it’s 20021120 and I’ve only just started writing the summary. Call me lazy, call me a shirker, call me anything you damn well please, just don’t interrupt me while I’m writing…
