Spring is in the air, the Apocalypse is here (or imminent, depending on which sense of the word ‘Apocalypse’ you are using). We’ll start with perl6-internals as usual, before bracing ourselves for the increased volume and ploughing on into…
Some Basic Concepts In order to understand what you might want to do with dates and times, it’s good to have a handle on some basic concepts. Here are some terms that I’ll be using in this article: datetime…
Ooh look, it’s another of those Perl 6 Summaries where Piers tries to work a gratuitous reference to Leon Brocard into a summary of what’s been happening to the Perl 6 development process this week. As tradition dictates, we’ll…
Editor’s Note: this Apocalypse is out of date and remains here for historic reasons. See Synopsis 06 for the latest information. This is the Apocalypse on Subroutines. In Perl culture the term "subroutine" conveys the general notion of calling…
In this article we continue talking about how to optimize your site for performance without touching code, buying new hardware or telling casts. A few simple httpd.conf configuration changes can improve the performance tremendously. Choosing MinSpareServers, MaxSpareServers and StartServers…
Welcome back to another episode in the ongoing saga that is the Perl 6 development process (or at least my attempt to describe it). We kick off with perl6-internals. IMCC calling conventions Piers Cawley attempted to describe tail call…
This is a book I have been looking forward to for a long time. Back when James Tisdall had just finished his Beginning Perl for Bioinformatics, I asked him to write an article about how to get into bioinf…
Another week, another Perl 6 Summary, in which you’ll find gratuitous mentions of Leon Brocard, awed descriptions of what Leopold Tötsch got up to and maybe even a summary of what’s been happening in Perl 6 design and development….
Building a Vector Space Search Engine in Perl A Few Words About Vectors Getting Down To Business Building the Search Engine Making it Better Further Reading Why waste time reinventing the wheel, when you could be reinventing the engine?…
Welcome to the all new, entirely unaltered, all singing, all dancing Perl 6 summary. Your beacon of reliability in the crazy world that is Perl 6 design and development. Another quiet week. Even quieter than last week in fact, unless…
Dave Rolsky is a co-author of the recently released Embedding Perl in HTML with Mason. This article was originally published in February of 2003, and was updated by Dave Rolsky and Michael Schwern in January, 2008. If you’ve ever…
Welcome to the latest Perl 6 summary, your handy cut out and keep guide to the goings on in the crazy world of Perl 6 design and development. It’s been a rather quiet week this week; only 75 messages…
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…
