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…

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…
