Once again I would like the thank the Perl Foundation for supporting me in my effort to provide a mechanism to ease the creation of Alien:: modules. Further I’d like to thank the many Perlers who have commented in various places that this project is of interest and that they are looking forward to providing that Alien:: module that they have always meant to write. This is exactly the response that I had hoped to receive.

Down to the details. This month I did a lot of work on Alien::Base; partially do the excitement about the grant and partially because our scientific camera was out for repairs, thus not much science going on in the lab. I hope to keep the pace high, but looking over the git log I’m not sure that they can be this productive! I’ll list some high points:

I almost could repeat the last post, But in an effort not to be boring: here are the exciting parts. I turned over to do something almost daily. Sometimes not much, but it turned out that i discover this way some dark dark corners of the spec and the tablets as well that really need some attention. And its so much fun to come up with keywords in the #perl 6 channel present people never heard of.

In a previous entry, I mentioned I will be giving a seminar for Oslo.pm next month: "Temporally Quaquaversal Virtual Nanomachine Programming In Multiple Topologically Connected Quantum-Relativistic Parallel Spacetimes...Made Easy!" .

The talk will be delivered at The Scotsman (2nd floor), Karl Johans gate 17 on Thursday 19 April, starting at 18:00. Admission is free and everyone is welcome.

See Salve's blog posting or the Oslo.pm homepage for full details.

Jonathan Swartz will give a talk at YAPC::NA 2012 described as:

Caching is a critical piece of any performance-sensitive website or application. CHI provides a unified, implementation-independent caching API - a “DBI for caching”. It works with the gamut of popular cache backends and offers features well beyond the usual caching API, such as probabilistic expiration, background re-computation, and multi-level caches.

The author will describe how to wield CHI for more flexible and effective caching, and relate some lessons managing hundreds of distinct cache namespaces on a high-traffic web site.

Hi Folks

I've just had some pain installing these 2 modules, so I've written up the experience
here.

I ended up confused, but I hope you avoid at least some of the problems...

read all about it in my Perl blog

Perlito5 is an ongoing implementation of perl5, with a javascript backend. The compiler is written in perl5. It compiles itself to javascript, so it can run in a browser.

The test suite can be run with node.js. It now passes 288 tests. About a hundred of these tests are from the official perl5 test suite.

$ prove -r -e 'node perlito5.js -Bjs' t
t/base/cond.t ...................................... ok
t/base/if.t ........................................ ok
t/base/lex.t ....................................... Failed 37/57 subtests
t/base/num.t ....................................... ok
t/base/pat.t ....................................... ok
t/base/rs.t ........................................ No subtests run
t/base/term.t ...................................... No subtests run

We’d like to thank our sponsors for stepping up to support us. We really couldn’t do this without their support.

You too could sponsor YAPC.

Boleh gak sih ngeblog di blogs.perl.org tapi gak ngebahas perl?

If you're not familiar with Dancer, it's a Perl framework written by Alexis Sukrieh and inspired by Ruby's [Sinatra](http://en.wikipedia.org/wiki/Sinatra_(software)) framework. Though some call it a "micro-framework", according to Wikipedia, Sinatra is used by Apple, BBC, the British Government, LinkedIn, Engine Yard, Heroku, GitHub, and Songbird. That impressive list shows that Sinatra, and thus Dancer, is far more powerful than you might think at first glance.

So far, while I love Catalyst, I've found that I'm hacking out a Web service much faster with Dancer than I would have with Catalyst and I used Catalyst quite a bit. I've submitted a couple of minor patches, but I'm very happy with my latest enhancement to Dancer.

Stockholm Perl Mongers and our fellow Nordic Perl Mongers arranges the annual Nordic Perl Workshop in Stockholm, Sweden in the beginning of the summer (late may / early june). This is the third time the workshop is arranged in Stockholm and the 10th time
in total.

Nordic Perl Workshop is a workshop for the community by the community and we want you to submit interesting and inspiring presentations in order to make the workshop successful. Talk lengths are the usual 20 and 40 minutes but we might consider
longer ones if motivated. Any subject is welcome as long as it's related to Perl somehow - from algorithms for social graphing and web-technologies to Perl5 core optimizations and language implementation targeting the Parrot VM. To submit a talk either do
it online on the workshop website[1] or to claes at surfar.nu. If submitting via email please prefix the subject with [NPW].

Please submit talks no later than Monday 30th of April. Accepted speakers will be notified Friday 4th of May.

Using multiple windows, multiple tabs, code folding, auto-complete, perl-support Vim script and taglist source code browser script.

Registers, markers, jumplists are not very expressive in a screenshots. Anyway I suggest Vim users to try the perl-support plugin. It may considerably speed up your development process.

It always amuses me when I see people talking about Vim or Emacs using words like primitive editor. I know that those people are usually the kind of people that have no idea what these editors can do without that much customization. Also regarding speed, they are usually no match for a Vim or Emacs experimented user.

(I used to be a Java programmer using Netbeans and Intellij IDEA not long ago :). In fact I still use Java occasionally.)

As requested in the Fight Night post, here is a screenshot of a Perl file loaded in Vim (in this case CGI::Simple).

Hi Folks

Yesterday I had an unpleasant experience trying to install Perl's BerkeleyDB (article to follow), during which I spent a long time fiddling with my ~/.bashrc and ~/.profile files, trying to set LD_LIBRARY_PATH to make that module accessible. Hint: I was on the wrong track.

In the end I wrote an article to clarify what bash runs, in what order. This is basically a note-to-self, but I hope others will benefit too.

Bash and Its Startup File Execution Algorithm

Pod::Perldoc is a "dual-life module" that ships with Perl core, but also sits outside of it. Over the weekend, I released Pod::Perldoc 3.17 which incorporates several bug fixes and adds several new features.

In the latest release we've:

• Added better support for UTF8 in the pod -> *roff -> *roff-formatter -> pager pipeline - unfortunately a lot of UTF8 support for pod remains at the mercy of *roff-formatters. People running perl on Mac OS X, for example, will get old crufty versions of groff that do not process UTF8 input, even though Pod::Man supports UTF8 output.

• Improved support for $PAGER and $PERLDOCPAGER definitions that expect pipelines or input redirection

• Improved behavior of -l -q

• Added two new formatter classes (ToANSI and ToTerm) which bypass many of the UTF8 problems with *roff-formatters.

• Made it easier for downstream utilities to define their own command line arguments

• Closed over 20 bug tickets on the RT queue. Some of these bug reports were years old unfortunately.

I'm finally taking advantage of the co-maintainer bit that Yuval Kogman gave me last year and putting out new releases of MooseX::App::Cmd.
