I have started compiling summaries of the Perl 5 Porters (p5p) mailing list. Thank you to everyone who helped improve them. Following is the first report.

My August assignment (yes, I had to "stick" with it for September) in the CPAN Pull Request Challenge was Test::Aggregate. In August, I went on vacation, and CPAN Testers' reporting was down, so I decided to solve the task after I return from the YAPC in Granada and ask for a new distribution for September with a two-week delay. It wasn't that easy, though.

When I started working on P6SGI, I thought, "Hey, I'll just update PSGI to use Perl 6, take advantage of some async data structures, and be done." That is not how this process has gone down. First, I learned that I needed to know more about Perl 6. Then, I found that I need to know more about HTTP/1.1 and more about PSGI. Most recently, I have been researching HTTP/2, Mojolicious, WebSockets, Akka, and a whole pile of other things.

So, here's the progress report on thing that have changed in the last week or so on our way toward a complete P6SGI standard, which is still a ways off.

So I really like to validate email addresses using Email::Valid. But yesterday, I got a bug report. Some system was sending emails to another system with addresses containing a space right after the @. That other system was totally unable to deal with those.

"But I do email address validation" I thought. "Not just with a stupid regular expression like .+\@.+, but with Email::Valid". So I added a test to our suite and sure enough, that new test failed.

Lesson learned: Read the documentation of the modules you use.

Greetings Perlites,

We're continuing our trend of success with...

THE RPERL CHALLENGE!!!

After watching the video linked above, you'll want to head over to Kickstarter:

Thanks in advance for your financial support, it is critical to the future of RPerl's performance future!

Just to give people an update on where I am after the spill and subsequent events at YAPC:

First of all, I need *AGAIN* to give my thanks to:

@Amal1a_ (Amalia) (and everyone else at Evozon for supporting me)
@renatolrr - (Renato) YAPC Coordinator, gofer and frequent bedside supporter during the last 3 weeks of hell
@Makova65 - (Manu) Another bedside confidante and inadvertent Andalusian Spanish tutor
@jjmerelo - (JJ Merelo) Another coordinator, gofer and @YEF director, I think.

And those that I can't find on Twitter - Maribel, Victor, Pablo, Paloma and Jose. Pretty much everyone responsible for YAPC::EU 2015, probably.

I can't thank you enough, you made my last 3 weeks bearable, I'm not sure what I would've done if I were just staring at off-yellow hospital walls for 3 weeks. I *SHALL* return to Granada, and Manu, I *will* take you up on your offer.

And now for a more personal update.

We are offering an one day DBIx::Class training in Vienna on the 20th October. For details please check:

https://www.perl.dance/talks/23-dbix-class-training

The training fee will be only 149 € if you book until 28th September. Please contact me by email in order to buy a ticket.

[This is the first post in a new, probably long-ass, series.  I do not promise that the next post in the series will be next week.  Just that I will eventually finish it, someday.  Unless I get hit by a bus.]

The topic arose at $work recently: what do the cool kids use for dates these days?  Our sysadmin was looking for a simple way to get “tomorrow.” Of course, the cool kids are theoretically using DateTime, right?  So, how do we get “tomorrow” out of DateTime?  The answer came back in our chat room:

Datetime->now->add(days=>1)

Well, okay ... that would work.  But it’s not exactly what I’d call “easy.”

Greetings, Perl Lovers!

I am proud to announce the launch of our next Kickstarter campaign.

We immediately reached our minimum of $1,701; now our goal is to reach $20K in the next 9 days. We can do it... WITH YOUR HELP!

STEP 1: Make a generous pledge.
STEP 2: Get your friends to match your pledge.
STEP 3: Get your boss to double your pledge.
STEP 4: Go back and increase your pledge.
STEP 5: PERL WILL BE THE FASTEST LANGUAGE EVER.

Thanks so much for your continued support of RPerl!

I gave this talk at MadMongers showing how to do cool special effects with imager, like rendering realistic 3d shadows from a 2d object.

All the effects herein, were used to create my new game Hamlet Builder Pro.

[From my blog.]

We have five proposals to review, including the one from July.

A few months ago I write about using arbitrary SQL to generate DBIx::Class resultsets. These DBIx::Class::Report resultsets are read-only, but I found that I needed to add additional methods to each result and now I can. This makes the software much more flexible.

Strawberry Perl 5.20.3.1 is available at http://strawberryperl.com

More details in Release Notes:
http://strawberryperl.com/release-notes/5.20.3.1-32bit.html
http://strawberryperl.com/release-notes/5.20.3.1-64bit.html

I would like to thank our sponsor Enlightened Perl Organisation for resources provided to our project.

I just tried to add perl 5.22 to the list of perl I run my tests on, but it seem Travis-CI does not support perl 5.22 yet.

This reminded me that it would be nice if I could configure Travis-CI to use a flag such as 'latest_production' that will always use the latest version of perl available in Travis-CI so when the finally add 5.22 the "latest_production" will automatically pick up that version.

It would be also great to have 'blead' that would use blead perl for testing.

Is any of these possible today?

I've been working on a Bayesian spam filter, but it keeps running out of memory, so I moved to something else for a while. The new concurrency stuff looks really interesting, but I don't understand it well yet. As a project, I came up with the idea of a password cracker, which would check a crypt-style hash against a word list. (This probably isn't a CPU-intensive enough task to be worth threading, but it was simple.) Here's the code, with details below:

Hi!

I have just started a repository of portable web tests - http://swatpm.org
This is an alpha stage. Please follow up:

- Read what swat is
- Create your test suite useful for others
- Publish it to CPAN
- List it to http://swatpm.org

I've been digging into Perl 6 more lately and I noticed the Wikipedia example of fluent interfaces didn't have a Perl 6 example, so I fixed that.

To be fair, Martin Fowler's explanation (as usual) of fluent interfaces does a much better job of explaining them, but a key point is that setters have a return value. For many fluent interfaces, the setters set a value and actually return a new instance of a different object for you to call methods on. Thus, the examples in Wikipedia don't always meet the criteria of a fluent interface, but I added a Perl 6 version that closely modeled the PHP version (but more concisely, and with much better type safety). I sidestepped the entire fluent interface debate.

Thanks a lot for your questions. We hope you find many of them answered in the video, where Will "Coke" Coleda asks Larry Wall your Perl6 questions.

• The language links were moved to the right-hand side.
• Articles that belong to any of the series linked from the front page show a Prev and a Next button.
• On the left-hand side they will show the list of all the articles that belong to this series.

For example you can check out the Perl tutorial, the Beginner Perl video course, or the project building an open source clone of search.cpan.org.
