Open Source Day 2011 - report

The Cattle Grid

28 November, 09:52, by Michele Beltrame, machine translated from Italian

Well ... I am here with a few lines on ' Open Source Day 2011 . In total, a large event - with 3 concurrent tracks and plenty of participation of people would say. Unfortunately, I just followed the conference, since I ran the table of ' Perl.It Association . But I had a look here and there and did not seem to miss interesting talk. Very appropriate the idea of the speed of talk: a space where anyone could engage in the hallway talking about something quickly - ideal for those who want to make a brief intervention or is not used to speaking in front of an audience and maybe wants to start a more " soft ".

There was the inevitable Install Fest, where in practice one takes your PC that wants to install Linux or another open source operating system and can get help with installation and usage information for the system. Nstall The Fest always an important and useful in these events. The Game Corner seemed particularly interesting in the sense that everyone enjoyed themselves. Unfortunately during the day I have not had much time to try my hand and towards evening it was too late to fight competitively with those who had already become familiar with the shootings in the morning - so I just have a look. :-)

A good initiative, I have not seen in other conferences like this, it was the children's area. The name speaks for itself, and follow the conference can leave the little baby in the hands of the excellent team of Open Source Day, which will make him pass the time while having fun. Great idea!

The self-service lunch cost just 10 euros (OK, I did not pay as speakers actually) and it was pretty good and plentiful. The bar was always open and available at the University of participants.

The only (small) in fact I do for a successful event, however, is related to the lack of an evening event: there was a dinner would be nice "social" planned (which is a pre-enrolled, or pays the same day if there are still places), are certainly not lacking ideas for various technical discussions and not to make friends, and (why not) to pull around later in Udine. ;-)

perl new features

[Introduction Amon2] Introduction lightweight framework Amon2 ~ Let's write a plug-in here is abrupt (10) ~

25 November, 10:06, by tokuhirom, machine translated from Japanese

Sometimes I hear that you are unfamiliar with the story writing plug Amon2, I would like to explain that strange.

Basically, just plug-in is a Perl module, not a problem according to the terms of a single. Is that it has a class method called 'init'. That's it.

package MyPlugin;

sub init {
}

1;

This is valid for one plug.

Well, There is no use making a plug-in so it does nothing, try adding a little feature.

package MyPlugin;

sub init {
    my ($ class, $ context) = @ _;
    $ Context-> add_trigger (
        AFTER_DISPATCH => sub {
            my ($ self, $ res) = @ _;
            $ Res-> header ('X-Framework' => "Amon2 / $ Amon2:: VERSION");
        }
    );
}

1;

This is a fine plugin. Is as simple as tapping the trigger AFTER_DISPATCH.

If Hayashitai or method is as follows: do I.

package MyApp:: Plugin:: Web:: BrowserDetect;
use HTTP:: BrowserDetect;
use Amon2:: Util;

sub init {
    my ($ class, $ c, $ conf) = @ _;
    Amon2:: Util:: add_method (
        $ C,
        'Browser',
        sub {
            $ _ [0] -> {browser} | | = HTTP:: BrowserDetect-> new (
                $ _ [0] -> req-> env-> {'HTTP_USER_AGENT'}
            );
        }
    );
}

1;

In addition, the third argument of the init is hashref that can be passed as follows.

__PACKAGE__-> Load_plugin ('+ MyApp:: Plugin:: Web:: BrowserDetect', + {configuration => 'Here'});

And oh, what's it. Just plug-in, so come and simple configuration hashref containing the name of the context class, then please enjoy the value of meta-programming perl, and making it simple.

As for plug-ins, and I think I do not publish to CPAN Once you have more and more viable in general (I have received better reviews from such PrePAN).

Unlike a plug-in Agen Catalyst! Say it solved.

YAML

Converting "firs»

Shoor/нал

24 November, 11:41, machine translated from Russian

Tried to convert text to UTF-8 would result in missing in KOI-8 punctuation to a form suitable for HTML:

 use HTML:: Entities;
...
my $ fixed = encode_entities ($ raw, "\ x {460} - \ x {2E2E}");

Worked strange dash was converted into — and quotes, Christmas trees - no. The reason was simple - the quotation marks in Unicode-firs are not there, where other punctuation with spaces - not in U +2000- U +205 F, and much closer - their codes U +00 AB and U +00 BB, that is, if we translate to decimal, 171 and 187. Sound familiar? :-)

Therefore, a more correct version is as follows:

 my $ fixed = encode_entities ($ raw, "\ x {A0} - \ x {40F} \ x {460} - \ x {2E2E}");

Perl in the Cloud - open shift Express by Red Hat - installation, configuration and initialization

Perl HowTo

24 November, 11:22, by Thomas Fahle, machine translated from German

open shift by Red Hat simplifies the development of open source applications for the cloud. This platform-as-a-Service provides an infrastructure for various programming languages and web frameworks are available.

Red Hat is different between the product variants Express , Flex and Power .

The free Express version ( registration required ), including allowing the use of dynamic programming language Perl in version 5.10.1, the database MySQL in version 5.1 or SQLite version 3, and (most importantly) the installation of modules - modules .

The well-known and popular Perl web frameworks Dancer , Mojolicious and Catalyst can be used.

Step by step

This paper will first step through the installation, initialization, and configuration of open shift Express. After that, a decidedly simple but useful Perl program creates and shows how this comes in the Cloud (deployed) is.

Registration

To use an open shift Express is registering with a valid e-mail address REQUIRED. Alternatively, an existing RHN account to be used.

Installation of Client Tools

open shift work under Mac OSX, Linux and Windows - for this post, I use CentOS 6 (64-bit in its own virtual machine).

For the client tools, Red Hat has a own YUM repository, as follows installed is.

# Wget https://openshift.redhat.com/app/repo/openshift.repo
Openshift.repo # mv / etc / yum.repos.d

To ensure that all package dependencies are resolved, I had to get the EPEL - and Freshrpms repositories to add .

Now the client tools are installed:

# Yum install rhc

Initialization

All apps are installed by a user in its own name space (domain). Apps are then publicly after the scheme http:// $ app $ domain.rhcloud.com accessible. More on that.

The command rhc-create-domain creates a new namespace, the configuration file express.conf and SSH keys (libra_id_rsa) to Git authentication.

$ Rhc-create-domain-l-s yourdomain user@example.com
Password: &lt;user password>

Generating Express Open Shift key to ssh / home / username / .ssh / libra_id_rsa
Generating public / private RSA key pair.
Created directory '/ home / username / .ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in / home / username / .ssh / libra_id_rsa.
Your public key has been saved in / home / username / .ssh / libra_id_rsa.pub.
.
.
Contacting https://openshift.redhat.com
Rhlogin Adding to / home / username / .openshift / express.conf
Creation successful

You may now create an application. Please make note of your local config file
in / home / username / .openshift / express.conf Which has been created and populated for
you.

Now configure Git (minimal)

DateTime:: TimeZone: rake

22 November, 13:40, machine translated from Russian

I should not cancel after the transition to the winter fun of php-shnik. In the marketing module perl-DateTime:: TimeZone base hits though, and is generated on the basis of time-zones, but still his own. And, for example, in Debian stable for Moscow now is the time from UTC is converted incorrectly.

Recipes:
1. The most correct, perhaps, to update the module
2. For those with a batch repository - rebuild the package and deliver it.
3. Minimum, he's wrong - copy the appropriate description of the new version of the module.
4. Still, given that the supply module, judging by the comments, is a tool that parses and generates tzdata modules corresponding taymzonam, you can use them.

We look for Perl / C programmer udalenku with extensive experience in the development of frontend / backend heavy-sites.

Attendance million unique visitors per day to the server. Iron works at full capacity.

All the software is written in Perl + MySQL + third-party template. Need to constantly introduce new additions to improve performance, up to rewriting frontend / backend completely. Plus auxiliary software to write Perl.

Just need to configure the server (Free BSD) to the needs of the software. Those issues that will decide the admins, you can redirect them unnecessarily to the full server administration, hosting providers.

ZP on probation 2 months (in conjunction with the old computer programmer) - 45 tys.r ($ 1,500) / month. then 75t.r. ($ 2,500) / month. In the long term may be extended up to 120 tys.r ($ 4,000) for performance. On probation can pay for a week. Payment WebMoney WMZ or at one of the card payment systems.

Schedule a free, 7-8 hours a day. With good performance, maybe less. Other part-time work are not allowed on the side, unnecessarily just to think about our software.

Mandatory condition - a permanent presence in the ICQ and the ability to connect to the Internet no later than 1-2 hours after my call at any time, in case of an emergency, for example, did not rise after soft reboot the server.

[Introduction Amon2] Amon2:: Setup:: Flavor:: Introduction to Amon2 lightweight framework for simple board ~ Creating Large + Teng (7) ~

20 November, 19:00, by tokuhirom, machine translated from Japanese

But over time I Oita from the previous tutorial in creating the application's start with Amon2 + Teng abruptly larger. The Teng of the types of libraries, called O / R Mapper, is to give easy access to the DB.

Well, start by preparing well anyway.

As already contain cpanm,

% Cpanm Amon2 Amon2:: Setup:: Flavor:: Teng Teng

Install in Amon2.

% Amon2-setup.pl - flavor = Large, Teng MyBBS

Because you've got skeletons

% Cd MyBBS

As, enter the directory for the project.

% Cpanm - installdeps.

If you are installing the module dependency.

% Plackup app.psgi-R lib

Ice as part starts the server process.

http://localhost:5000/

When you access the browser, making it look like the home page.

For now, let's create a simple board. The ideal in the door.

Since the front page template tmpl / pc / index.tt, 書換Emashou Gossori it first.

You will gain if I'll like this anyway. View the form in the upper part, near the bottom to show what was actually posted.

[% WRAPPER 'include / layout.tt'%]

&lt;form method="post" action="/entry/create">
    &lt;fieldset>
        &lt;div> &lt;textarea name="body"> &lt;/ textarea> &lt;/ div>
        &lt;div> &lt;input type="submit" value="Post New Entry" class="btn primary" /> &lt;/ div>
    &lt;/ Fieldset>
&lt;/ Form>

[% END%]

Now save the contents of the database in this forum. This time is made by using a Teng O / R Mapper. Because the database uses mysql, open the sql / mysql.sql, you may want to write as follows.

CREATE TABLE IF NOT EXISTS sessions (
    id CHAR (72) PRIMARY KEY,
    session_data TEXT
);
CREATE TABLE IF NOT EXISTS entry (
    id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   body VARCHAR (255)
) ENGINE = InnoDB DEFAULT CHARSET = utf8;

I think the first table from the beginning that Kakare.

Let's configure the mysql database subsequently.

mysqladmin-uroot create mybbs

Creates a database named on the command line mybbs depression and so on. If you set a password, please perform a setting such as at any time.

mysql-uroot mybbs &lt;sql / mysql.sql

Keep the schema as an in-depth.

Writes to the database connection settings in the config / development.pl. This file is the configuration file, so just a perl script, write the logic to love. What can safely Once you have the last to return a hash reference. Configuration file is determined by the environment variables, config / $ ENV {PLACK_ENV}. Is a file named pl. The default is set to development.

Please try to set something like this:.

+}
    'DBI' => [
        "Dbi: mysql: database = mybbs",
        'Root',
        ''
        {Mysql_enable_utf8 => 1}
    ]
};

Now, as people are set in the finished now, let's write the code finally.

"Lib / MyBBS / PC / C / Entry.pm" to open the file, write as follows.

package MyBBS:: PC:: C:: Entry;
use strict;
use warnings;
use utf8;

sub create {
    my ($ class, $ c) = @ _;
    if (my $ body = $ c-> request-> param ('body')) {
        $ C-> db-> insert (
            'Entry' => {
                body => $ body,
            }
        );
    }
    return $ c-> redirect ('/');
}

1;

This time MyBBS:: PC:: C:: Entry:: From I defined a method called create, this method is mapped to the URL / entry / create. Methods defined in this manner, when using the Large Flavor that is meant to be automatically mapped to the URL. For the implementation of this area, please look at the lib / MyBBS / Web / Dispatcher.pm. Also, what is the method which maps to the URL, you can check messages when you start plackup.

Let's look at the contents in finer. $ C before but also have a context object. This object MyBBS:: is an instance of the Web, MyBBS:: Web is a child class of MyBBS.pm. About this operation is done through an object.

$ C-> request is an object representing an HTTP request. Used when dealing with information regarding the HTTP request. This method Amon2:: Web:: Returns the instance of the Request. When called to see the contents of the HTTP request. Here the value of the parameter to get the 'body'. $ C-> request from a method frequently used, $ c-> abbreviations are also provided that the req. Amon2:: Web:: Request is Plack:: Because the child class Request, if you find information on available methods for this class Plack:: and you should read the documentation for the Request.

$ C-> db method returns an instance of Teng. This is a feature of the method has been Amon2 solid writing in lib / MyBBS.pm without. Concerning operations in the database is done through this MyBBS basically.

$ C-> db-> insert method is a method to issue an INSERT statement in SQL.

INSERT INTO entry (body) VALUES ('hogehoge');

Such a query is issued for.

$ C-> Amon2 and methods referred to redirect ('/'):: Web:: Response object is generated. Amon2 world, the controller is all Amon2:: Web:: Response (Plack:: Response) has to return an instance. Just received the request sends a response. That in this case

302 Moved Permanently
Location: http://localhost:5000/

Will generate a response like.

Now, type in the past can now be

Grammar in Java, Perl 6 and Perl 5

zag's personal blog

14 November, 12:00, machine translated from Russian

Grammars are generally set the "rules" by which to determine the language constructs that support the same arbitrary nesting. Scope of the grammar - sophisticated parsing of text or data [1]. Grammars can not do without, in the case of compiler languages, interpreters, etc. Lately I've been using tight grammar in Java, Perl 6 and Perl 5. Shall explain briefly about them in each language. Grammar in Java JavaCC (Java Compiler Compiler), perhaps the most popular parser generator for Java. Includes utility JJTree to build syntax trees. Syntax for defining rules are simple: an element of grammar, a list of elements of grammar and an alternative list. For example, the following token defined by the numbers and the numbers: TOKEN: {<NUMBER: ( ) + ("." ( ) +)? > | <DIGIT: ["0" - "9"]>} Examples of grammars can be found in the repository of JavaCC grammars [2]. Grammar Perl 6 in Perl 6 grammars are part of the language and this is one of the most remarkable Fitch language. Therefore, there is nothing surprising in that the syntax of Perl 6 is described by his own grammars [3]. Perl 6 grammars in fact represented in the form of classes and can inherit other grammar. The processing of the text can be combined with the construction of a syntax tree. To this end, the parser is passed a parameter action, whose value is an object handles matching tokens (in Perl 6 they are tokens and token rule). For example: my $ res = Plosurin:: Grammar.parse ($ txt,: actions (Plosurin:: Actions.new)); handling of $ txt, in case of identical tokens, to construct an abstract syntax tree (AST) will be called the object's methods Plosurin:: Actions. The results of the call will be part of the result tree. This integration into a programming language to simplify the use of grammar. How much more? You can for example compare the grammar definition for processing JSON for JavaCC [4], and Perl 6 [5] (for clarity, in a gist [6]). Grammar in Perl 5 to Perl 5 grammars implemented as a module Regexp-Grammars [7]. The following example from the documentation of the module shows the rules for parsing LaTeX: use Regexp:: Grammars; $ parser = qr { <[Element]> * | \ \ ? ? \ [<[Option]> +% (,) \] \ {<[Element]> * \} [^] [\ $&%#_{}~^ \ S,] + [^] [\ $&%#_{}~^ \ S] +} xms; those who are familiar with Perl 6 grammars, the example above will look familiar. On the surface, and on opportunities Regexp-Grammars is very similar to Perl 6 grammars: inheritance is, the construction of a syntax tree. And in terms of functional debugging rules even better than Perl 6. Regexp:: Grammars one of those libraries, which are very useful to know! NOTES1.

Yaffas is a simple framework written in Perl administration of servers. On the 11/11/2011 version of the project was 1.0 = 197 & cHash = published 92f323410321f628e260bc7eaaf7ba99]. Linux server administration without any command-line knowledge - that allows the first final release of yaffas. The web-based administration interface makes it easy to monitor and manage services, configure the network and managing users and groups. Also can be managed via the included yaffas mail server with Postfix as a Mail Transfer Agent and configure also contained anti-spam and anti virus programs SpamAssassin and ClamAV. In groupware supports yaffas management including resource management of the integrated Zarafa groupware server (version 7), and backup and recovery elements of groupware such as e-mails and calendar.

When installing packages from Graphics:: Magick is placed, but to put it in a separate ubuntu, which is not obvious, because the documentation on the site says that it is placed immediately with gm.

Well, that too sadly, the stable version of the year with a tail, is unstable, as amended, and new chips on 7 of my 22-inch screens, but it is clear that unstable there better not to put into production. In general, would be stable releases at least once in three months - it would be much better.

Writing in Perl in a functional style

Записки программиста

7 November, 06:00, by Eax, machine translated from Russian

Shortly after they met with Haskell, I've noticed that some problems can be solved easily painfully with the functional approach. It appeared quite natural (for me) issue. Is it possible to apply this approach in Perl? One possible solution that comes to mind is to write a shared library in Haskell and load it into a [...]

Abnormal programming / [From sandbox] Write a bilingual program

6 November, 18:48, by cyberpunkyc, machine translated from Russian

Recently, I faced a difficult little problem that I threw a friend. The bottom line is that by writing a source code, you can compile it with gcc and executed, and also through the interpreter to execute perl. It would seem, is not that difficult, but not all programmers will think how to write this source. Proceed to consider the original programs in C and Perl.

What hourly rate for perlovika is now considered a "great deal"?

5 November, 15:44, machine translated from Russian

In short, I was approached by an old client to help finish the project in Perl. I am too lazy to bother with this, I want to call defensive hourly rate, but that it is not doubted my sanity. How much are the average hourly wage ceiling for the super-duper-perl programmers? 70 bass per hour? 90? 40?

Maybe someone faced with a similar?

There is a demon on the basis of XML:: Compile:: SOAP:: Daemon , to which are connected modules with global variables and all sorts of useful functions (including pulling data from the database).
To it requests are sent through the test client script.

When querying, where the appeal to the functions of most of the connected modules, if the function accesses the database, the client script reports an error 500. Judging by the debug records demon tries to execute a call neinitsializovannoy dbh-variable. With access rights to files at the same time everything is in order, a module with functions in the same folder as he sees and is normally in the function.
Race conditions, like, too, no problem occurs even if the query one.

If I call the same function of the module from the demon itself directly, not through the client, it works.
If I shoved the same code database query into a demon, without plug-ins, and everything works with a client, too.
If the database query functions not everything works, too.

What is at least theoretically could be wrong?

Winter 2011: The 20th edition of the Perl magazine "$ foo" is here!

Perl-Blog

1 November, 12:18, by ReneeB, machine translated from German

Even the ghosts are creeping through the streets yesterday, could not stop us. Today, the new edition of Perl magazine "$ foo" is released. Subscribers should receive in the coming days and post the online version is already available. Happy reading!

Website: http://www.perl-magazin.de

Inside this issue: * SNMP:: Info Thomas Fahle shows in his article how to use the module SNMP:: Info very simple example gets information about Cisco router. * Review - Programming for this edition Breunung Herbert has read two more books. This time there are "seven languages, seven weeks" by Bruce A. Tate and "visionaries of Programming" by Federico Bancuzzi and Shane Warden. * In multithreaded programs Embed Perl Perl is a scripting language that can be embedded easily into the C programming language. This allows to use Perl code directly from C and the advantages of both languages (faster code in C compared with fast code written in Perl) to unite with each other (this is known in particular through mod_perl, which embeds Perl into the Apache web server). In the case of parallel access to Perl from a multithreaded program, the embedding is not trivial, since the Perl interpreter itself is not thread-safe. * $ Foo as an ebook The articles of this magazine will be delivered in Pod format. But as it is an ebook? This article shows how using CPAN modules, the pod is converted and is generated from this ebook. * Perl for presenters Nothing is more embarrassing than a live demo during a presentation that does not work. In this article two modules are presented that allow presenters to simplify life. * 2D OpenGL Game Programming - Part 2 In the first part was shown how objects are drawn and how the surface was built for the game "PONG". In this issue shows Tom Kirchner, as the players and the ball is animated. Shaders are also an issue.
