After one year of development mt-aws-glacier vsespb/mt-aws-glacier, mt-aws.com App::MtAws moved from beta status to stable.

It's written in Perl for POSIX systems (there are reports of successful use under Linux, BSD, MacOSX, Solaris).

It does have extensive testsuite, minimum dependencies, "full" unicode support (well, of course it's not full. there is probably no single application with full support),
multithreading implemented using fork(). HTTP(S) using LWP::UserAgent with workarounds for existing issues. Total SLOC is over 20k, more than 1000 commits.

Full list of features: here

Mojolicious’s 4.0 release came with lots of shiny features but it also came with a lot of housecleaning. One of the old things swept away was the memorize helper, which would cache a part of a template and prevent its repeated evaluation. Do you miss it, as some users undoubtedly do, or else does this helper sound useful to you? Then read on, because its back and better than ever!

I have a quick sanity check I'd like to throw out there.

I've been working all week on Alien::TinyCC, and I made some great progress. My initial distribution wasn't properly checking that the build steps completed successfully, so I wasn't getting any useful information back from the smoke testers. Once I fixed that, I started to get some useful feedback. Mostly.

Disclaimer: the docs things starts at paragraph 3.

Within 2 Weeks I was in Kiev and St. Augustin, giving 6 instances of 3 talks. My minireport on Kiev got published (in German) but there is a lot more to say of course. In Kiev Wendy talked me into the frogcon (the frog is the official logo because if you add an H ...) thing. And it was the best Perl booth/dev room we had ever there and i had a nice kinda YAPC after party, which sparked some thought what could be improved for the Perl world.

The other day I wanted to send a patch to WWW::Mechanize and it turns out it is now hosted within a Github organization called libwww-perl.

Then I read a comment by Ether, about the Perl-Toolchain-Gang, another Github organization with several members that maintain a bunch of modules.

The perl6 organization on Github includes many Perl 6 related projects.

Then there is the perlorg organization that holds the source code of the Perl.org, CPAN.org and PM.org.

I am really glad to see such cooperation is on the rise among Perl developers. This might also lead to more people contributing to these modules.

Maybe other CPAN developers would also want to move their projects under such umbrellas. Are there other such "github organizations" for Perl projects?

Some months ago, I read an article by someone who teaches Perl to Java programmers.  In it, the author wonders a bit about some of Perl’s features which seem counterintuitive to those coming from a Java background.  As you might expect, one of those features is its typing.  He says:

For example: stern, protective type safety is not only missing from Perl but actually not even considered particularly desirable.  Perl is relaxed.  The reaction from students is, naturally: “Isn’t this a huge obstacle to getting anything done?” Obviously the answer is “No”, but even after all the Perl I’ve written I sometimes wonder why not.  Is it really just the fact that it takes less time to type method signatures and variable declarations?

At the time I read this, I thought to myself, “Hey, I know the answer to that!” But I just jotted it down as a potential blog topic and let it percolate for a bit.  Many folks reading this will also know the answer, but it’s an interesting topic, and I’m sure someone will get something out of it.

In the following I describe how to build (from scratch) a simple Catalyst application that acts as a service bus for a collection of other Catalyst applications.

Here I'm using the term service bus to describe an application that provides web services to other applications (rather than, say, a JavaScript enabled web browser). This service bus acts as a central hub, taking requests form applications for tasks that sit outside their scope and either executing those tasks or passing them on to other applications.

The following assumes you have a working Catalyst development environment (see www.catalystframework.org for instructions).

A Service Application

Our service bus will communicate with the other applications using simple HTTP requests and will pass data using JSON strings. Let's start by using the Catalyst helper script to make a Service application:

> catalyst.pl Service
...
> cd Service

I released GitPrep 1.2. You can install portable GitHub system into Unix / Linux easily. It is second major release.

Because you can install GitPrep into your own server, you can create users and repositories without limit. You can use GitPrep freely because GitPrep is free software. You can also install GitPrep into shared rental server.

GitPrep (Document and Repository)

Features added in 1.2 are:

- Added import_rep script to import repositories. If you have many repositories, you can move these easily.
- Add blame page. you can know who change source code.
- Add the feature to import branch from other user.

Repositories Importing script is good feature because moving repositories become easy.

Example

You can try GitPrep example.

I recently updated File::Temp and wanted to standardize how we were creating temp files. Most places were using File::Temp already. I ran across one file where we using IO::File and returning both a file handle and the filename. I changed it to simply return a File::Temp object.

I rolled the change out to a test system and noticed a problem... All of our generated files were empty! I traced the problem down to using the File::Temp object with File::Copy's copy subroutine. I suspect it's the tied file handle bug biting us but the fix was quite simple.

Old: copy( $fh, $dest );

New: copy( "$fh", $dest );

Perl6 is at a turning point. Now running on 2 virtual machines (Parrot and JVM), with 2 more coming available in the next months (Javascript and MoarVM), with abstract concurrency on the JVM now and full Perl 5 interop at the horizon in MoarVM.

To make it easier for past, current and future Perl 6 contributors, we have asked Jonathan Worthington to give an intensive 2-day workshop taking a deep dive into many areas of the Rakudo and NQP internals. This is your chance to get up-to-date with Perl 6, specifically with Rakudo and NQP.

The workshop will mostly be focusing on the backend-agnostic parts but with coverage of the JVM and future MoarVM backends too. While the overall focus will be on getting to know the Rakudo and NQP internals, we'll also build the odd small language and object system along the way to get a better handle on the primitives.

It will be held in Frankfurt am Main, Germany, on 14/15 September 2013

We would like to invite you to our conference in Hancock, NY.

The conference focuses on Open Source software and general topics regarding eCommerce (Payment / PCI-DSS, ERP, Best Practices, Usability, SEO, ...).

We are specially interested in speakers and attendees from the Perl Community, as our usecases are based on Modern Perl and Dancer.

The conference takes place in Hancock, NY from 8th to 11th October and can be combined with the Pittsburgh Perl Workshop on the weekend before.

The call of paper is here:

I am Yuki Kimoto, Japanese Perl programmer. I create tutorial site in Japanese and English. I create Perl module and upload it to CPAN. I create Web application in Github.

• Yuki Kimoto Perl info - Author Site
• Perl Tutorial by Code Examples(Japanese) - Perl tutorial site
• CPAN or metaCPAN - My CPAN Modules, related to Mojolicious, DBI, Validator, etc.
• GitHub - I create Perl module and Web application, GitPrep, WebDBVier, TaskDeal, etc.
• Twitter(Japanese) - I post my news

Just as blog posts including images also documentation that includes images (even screenshots) is more plesant for the eye than just plain text. On both search.cpan.org, and Meta CPAN one can have images linked from the POD.

It would be awesome if more modules had a few images or screenshots included
and you can gain fame via the relevant Questhub Stencil.

MooX::LvalueAttribute - improved

Just a quick note to mention that following Mike Doherty's bug report, I've released a new version of MooX::LvalueAttribute.

This release (version 0.12) allows you to use MooX::LvalueAttribute in a Moo::Role, like this;

Based on feedback, I've made a number of changes to how the adoption list is created. They're summarised below, and described in more detail on my blog. We've had the first release from an adoption prompted by the list: Stephen Nelson has released Convert-BinHex (+1 his quest). This prompted me to create a Hall of Fame. Let me know if you adopt a module, whether it was on the list or not.

I am starting a project. The project is that my Lapanese perl tutorial site translation to English for perl beginners who speak English.

Perl Tutorial by Code Examples

I have translated most popular entry "Master Perl Basic Syntax Fastest".

Master Perl Basic Syntax Fastest

I list offten used perl syntax for Perl beginners. If people read this entry, people can learn perl basic syntax.

The 1.0 branch of SOAP::Lite has mostly stabilized with this latest release. Changes include 2 small bugfixes.

https://metacpan.org/source/PHRED/SOAP-Lite-1.06

Thanks to the contributors who have been giving great feedback and testing results.

Moops is sugar for writing object-oriented Perl. It provides similar syntax to MooseX::Declare and Stevan Little's p5-mop-redux. It's some glue between Moo, Type::Tiny, Function::Parameters and Try::Tiny, but for those occasions when you want the backing of a meta object protocol, allows you to easily swap Moose (or even Mouse) in place of Moo with very minimal changes.

Here's an example of a complete, usable class definition in Moops:

   use Moops;
   
   class Person :ro {
      has first_name => (isa => Str);
      has last_name  => (isa => Str);
   }

Without knowing it, both Steffen Mueller and I released modules this morning related to using the Tiny C Compiler for compiling C code at runtime! I have tried to make a fuss about mine (as evidenced by my blog entry this morning), but neither of us were aware of the other. Hopefully we can combine forces. Steffen, of course, knows an aweful lot more about typemaps and the available typemaps module ecosystem than do I. I plan to contribute the energy and enthusiasm! :-)

Check out Steffen's module on cpan and github.

My Alien module for tcc is on cpan and github, and my Perl bindings for libtcc are also on cpan and github.

There is one other module related to tcc on CPAN, called C::TCC. For better or worse, the module doesn't really provide a means for sending much to it, or getting much back from it, and the module author hasn't replied to my emails. Who would have thought that two folks would publish unlrelated modules on the same fairly unknown piece of software just over four years since the last thing to hit cpan?
