using simple syntax Dancer can quickly construct a Website.

Installation Dancer:

$ Cpanm Dancer

$ Dancer-a WebApp

WebApp will produce the Structure.

A basic post route:

Github often feel on the development of Perl Module README within the pod with the module file synchronization, maintaining a fairly trouble?

You can install the Module:: Install:: ReadmeMarkdownFromPod automatically module pod to markdown format readme.

Installation:

 sudo cpanm Module:: Install:: ReadmeMarkdownFromPod 

Use:

At Makefile.PL within:

 # In Makefile.PL

use inc:: Module:: Install;
name 'Some-Module';
readme_markdown_from 'lib / Some / Module.pm';

Finally perl Makefile.PL to generate Markdown format of the Readme, can be shown in the github project page.

Although similar to Perl's CPAN PHP's Pear and Pecl repositories available.

However, both the number of Pear or Pecl kit is not much, there are many packages are Alpha or Beta state, many packages also Text only detailed document.

Pecl package: 265
Pear package number: 569

So I am curious to check a bit Perl CPAN module number:

69899 Uploads

Gitalist: Git is the Web Viewer, use the Catalyst Framework as a Web client.

Git:: Fingerd: the @ rjbs written, via the finger command to query your Git Repository.

Git:: Repository: Git Repository of information can be read.

Git:: Bunch : to manage a Git Repository contains all the paths.

Recently a number of PHP Framework Survey of Benchmark, in general it seems most of the PHP Framework of the Hello Word, or if not open cache is not prefork apache worker, Requests per second is generally from 20 to 40 or 100 to 200 of the data are. As we leave alone open the Cache.

So take a look at Perl . Yes, yes, that is you in the eyes of the old CGI Perl.

But today has been different. Since Japan's Super Hacker Miyagawa wrote in early 2009 PSGI Spec version 1.0. Plack 's really done has been in active development by the world's attention.

Perl is different from PHP, is the first in the Server starts, all the code will be compiled into memory, Request comes in, can quickly executed, and PHP does not open in the cache, the Request is to be re-read each file interpreter PHP.

Plack

Perl world Plack, basically identical Rack Ruby's role, but also with the role in the Python WSGI. For Plack other issues, you can refer to Miyagawa written PSGI FAQ .

Use Plack, simple Plack Server (No Cache or Prefork) can make the Hello Word to 4000 req / s results, simply, is more than a hundred times in PHP, and PHP was through Prefork or only way to achieve this Worker effect.

Taken from Miyagawa's blog:

We'll show more numbers once everything gets stable, but so far the number seems promising and very interesting. Simple Hello World is now 4000 req / s with Standalone server with keep-alive on, and 2MB photo file serving runs fastest on AnyEvent server (300 req / s) with sendfile (2) and AIO enabled while other dumb implementation suffers from I / O in the perl land like (80 req / s).

Also mentioned Miyagawa, 2MB image file server, then use AnyEvent can reach 300 req / s. Perl actually do the other may only reach 80 req / s.

Starman

Then look Starman. CPAN top of the Description says:


Starman - High-performance preforking PSGI / Plack web server

The Starman's performance is as follows ( taken from CPAN ):

Here's a Simple Benchmark using Hello.psgi .

 - Server: Starman (workers = 10)
  Requests per second: 6849.16 [# / sec] (mean)
  - Server: Twiggy
  Requests per second: 3911.78 [# / sec] (mean)
  - Server: AnyEvent:: HTTPD
  Requests per second: 2738.49 [# / sec] (mean)
  - Server: HTTP:: Server

ActiveState is the Inter-old (founded fourteen years ago) software company, has been providing language Perl and Python packages and support the key players, especially in the Windwos platform. To do is turn into the most recent PaaS, early adopters are already programs offers developers, called Stackato , this set is based on CloundFoundry the real to do.

Phenona is among very young company, specializing in Linux / Perl / MySQL / Redis specific programs such as PaaS, founded just six months (depending on record to say that distinguish human thought has been brewing for two years pregnant) to be ActiveState acquisition , will be integrated into Stackato in.

Chong identified people Daniil Kulchenko, CPAN ID: dku Phenona explained the principle of selflessness . In fact, the package is based on Amazon EC2, and another in EC2 Linux Instance cut out in a smaller virtual host. Technology is used by LXC (Linux Container) , which is similar to FreeBSD Jail cutting way, not actually make a complete virtual machine, but cutting OS in the file, process, group, user access to other resources, to achieve similar results . This is why Linux only supports the main reason Phenona.

With dotcloud start, the competition has been evident PaaS to diversity, such as Heroku only supports Ruby Web App application side of this service, or like Linode , Gandi VPS , Rackspace can dynamically adjust the size of such VPS services, have been regarded as the last generation of product.

The whole concept of cloud and additional, younger generation will be dominated, people identified as Phenona record Daniil Kulchenko, currently 15-year-old high school student. Side of the future will finish high school, while at the ActiveState part-time.

It is the Young Hero.

In the Terminal in, [@ audreyt] [] written [App:: Uni] [] is a Unicode character can be used utility queries:

Yesterday, rewrite a bit, wrote a very simple Web App: Uni lost to [dotcloud] [] placed

The best use of such tools is to search a variety of symbols used, especially now that Unicode 6.0 has emoticon (from the Japanese mobile phone manufacturers to provide the text Yen symbol), but the moment there is complete coverage of the Unicode 6.0 font file literally, but also really did not. Only to find a set of [Symbola] [] fonts have all the emoticons (HE), the original author's site, there are many other ancient words of the font, the font file is not generally built to provide the parts.

The word free, and open licensing is very simple, what restrictions do not:

Perl circles in recent days began sweeping up the topic is: dotcloud PaaS vendor to provide this support PSGI out. And PSGI / Plack's maintenance personnel miyagawa will with immediate effect as dotcloud services. New owner new atmosphere, I wish him a flourishing career.

dotcloud Perl PaaS in the form provided by the class type Heroku, a PSGI App just passed up the entire directory can be used automatically. However, unlike Heroku only supports Ruby, dotcloud support Perl / PSGI, Ruby / Rack, Python / WSGI. Because Web App using Nginx with uWSGI.

In the use of the implementation will need to install a file dotcloud , the executable file is a python program, with the easy_install dotcloud can be installed. The directive provides much more detailed than heroku some. Ruby and python have provided the Worker. No perl in the Worker, but it surely does not need to wait too long.

Currently noted the following things:

• Open up the machine is EC2 Instance, through dotcloud ssh can not even go in operation. OS is Ubuntu Lucid. Lot of resources, RAM has 768 MB, / a 70G. But not the new open (a good start even go uptime is 89 days), I do not know is that the specifications are not fixed.
• ssh into the account is not root, not sudo . Will ask the password, but did not know the password what pipe. ssh key is automatically generated into the.
• If the local directory itself is a git repository, then the code will pass the way up is to use git push.
• Implementation of the perl app included with ubuntu is not perl, but 5.12.3, on the / opt / perls, this is a perlbrew root. But the path is not perlbrew, should be installed automatically during the initial good.
• cpan dependency of the installation is installed to ~/perl5 to go, like the contents of this directory under the local::lib style. Should look the implementation of cpanm --installdeps --L ~/perl5 . this instruction.
• Direct support static file, not in the hands as Heroku in config.ru feet.

Now go test the App is lost and the number of MoreText (but this site does not refer to the past), is basically the process went smoothly, unlike the Heroku so few steps, but DotCloud greater flexibility to provide the beginning.

The current account registered DotCloud still need an invitation code, price list are not seen. But this really enough PaaS packed easy to use, the strength of the trend has swept the Perl community (though you need to install python to use (laughs)).

In short, are interested, you can with what they Twitter: @ dot_cloud with the blog . You can also fill out the Email Web site to notify you let them.

Speaking about the time into the Perl module, not because they feel very satisfied with the existing, and was thus written a: Time:: Verbal

It currently features only difference between the two time points with the colloquial forms to display. ① The main features are very small units are discarded, and ② complete i18n / l10n support two.

For example, in Chinese:

 > perl -MTime::Verbal -E ' my $tv = Time::Verbal->new(locale => "zh-TW"); say $tv->distance(time, time + 7**$_) for 1..10;'不到一分鐘一分鐘6 分鐘40 分鐘5 小時昨天9 天66 天一年多一年多 

German:

Containing more than 60 languages. Content is translated from the rails-i18n plan. Can also customize the language translation.

Are at present to do the distance method is basically a Rails helper in distance_of_time_in_words , but not bad in this namespace can be supplemented with other parts of the succession.

For the time interval into a "3 minutes 29 seconds ago" The colloquial description of the module, there are four in the CPAN:

• Time::Duration
• Time::Elapsed
• DateTime::Format::Duration
• DateTime::Format::Human::Duration

Provided the first two inputs is a function of the number of seconds (for example 7240 such integers), the latter two is the DateTime::Duration object. If you do not have to meet rigorous results, and even some of the better fuzzy, then Time::Duration::duration of this function the best.

See the program and output compare https: / / gist.github.com/947706

DateTime::Format::Duration of the output format is to manually specify, so the comparison is not in the table.

Than an hour in the time interval, only the Time::Duration::duration function rounding second unit figures. But if you need to do I18N / L10N, but it is to win the other two mechanisms.

setter usually does not return the value, return the object itself using setter and then the other method and then call the object the way, is called cascading.

cascading of the most common example is jQuery, for example:

$ ('Div'). Css ({border: '1 px solid # ccc '}). Click (function () {}). FadeIn ();

Sometimes cascading take too long, the line was not any breaking, manual segmentation and indent again too annoying.

So wrote this plugin, cascading.vim

https: / / github.com/c9s/cascading.vim

Just finished a statement after the press -- would automatically according to the statement in accordance with cascading filetype segment.

For example:



But probably only support the current filetype ruby, perl, php, part of the indent assumes users expandtab situations indent, not deal with other conditions. There needs to be combined.

As people said, patches are welcome.

is a new technology if the value of people can feel a sense of the naked eye to commercial interests will not necessarily be improved. For example, Python or Perl web site do not work, no matter what the new framework would not affect whether the customer wishes to purchase the product. However, the developer adhere to the "XXX is benevolent to develop" just the behavior of developers love their characterization of Bale.

shell function, stuffed .bashrc or .zshrc before use. Used pbcopy content automatically cut to the clipboard (Mac limit). System, no such instruction can remove the case.

 pw () { p=`perl -e 'print map { chr rand(94) + 33 } 1..16';` echo -n $p | pbcopy echo $p } 

This program generates the image I:tx)C<!:'xn((AY such a strong password, useful to the uppercase and lowercase letters, numbers, symbols. If you do not want such a strong set of figures that can be adjusted 94,33 . for example, notes 10,48, it will produce only阿拉伯数字weak passwords. If the length of 16 characters do not have to, it will be 1..16 part into 1..12 or 1 .. 8, and the like .

If you do not automatically cut to the clipboard before the function, in fact, can change alias (note that more than one -l , to appropriate output line):

 alias pw="perl -le 'print map { chr rand(94) + 33 } 1..16';" 

Or make a separate program executable file.

This code, or the weight back down each time to play.

Happy New Year.

Duckduckgo is the author of a recent major search engine in use. There are several pleasing features:

• Keyboard interface - j, k, Enter, Cmd-Enter
• Special Q & A - ip, pw, yes or no
• He stood search -! Cpan perlbrew,! Ruby Number,! Yt Emacs
• Security - can be used throughout the https
• Anonymous - do not log the user's search history calendar

Full-text search results sometimes it does not feel as good as Google, can not adjust the time to do real-time search and so on. However, the keyboard can be used quickly before and after the visit (j up, k down) fifty, a hundred pen results, to want to see the first open in the background of the page (Cmd-Enter), or open in the current sub- Page (Enter), it became a very powerful and fast search tool for assistance.

If the search word in the knowledge base of several well-known (such as Wikipedia , CrunchBase , Wolfram Alpha ) of the known items, then DuckDuckGo presented the highest priority, and then the full-text search results. Most particularly, it has a special mark "Official site" (official website) function. If a keyword corresponding to the official website for direct, directly appear in the first. DuckDuckGo Goodies page illustrates a number of other available special keyword statement.

DuckDuckGo creators identified people (and programmers) are Gabriel Weinberg , also a CPAN Author: yegg . In his personal website, small detail illustrates DuckDuckGo server architecture , or even respond to a lot of other people's questions. Generally Perl / FastCGI / nginx / PostgresQL such a combination. (Know it is not, "came a Ruby On Rails" Web site after the general feeling particularly enjoyable.)

Most search services are discussed in the past in discussing the order of search results, rankings, scores, or advertising, etc., but DuckDuckGo convenient design in the interface can not help but back, again with a different point of view to think again "Browse search results "the problem. bing has also been demonstrated at the Apple WWDC on the use of the HTML5 to improve the use of the new design, although not seen as a real on-line design, but I was very happy to see. Google has also recently often a variety of revision. DuckDuckGo comparison is more like the design of "Hacker Friendly" feeling, just a little way to learn about those keyboard, you can use a very efficient way to fast operation, but, it is not difficult to learn.

Security and anonymity are the kind of "lost will feel important" things. Google Search has been relatively personal search history will remember, so if there can be more personal, more "satisfactory" ranking of search results, but always is linked to heart: I have so much information you record , What are they going to do will be used? On the other hand the more "personal" search results is not really very good, sometimes difficult to discuss. After all, good or bad search results when, in fact, more than imagined, in which subjective factors. In fact, PageRank is still a very simple calculation.

So far DuckDuckGo are free and no advertising of services, very nice. Not sure they have this service without any profit, but I hope the good service will continue.

MT5 with for a while that one of the "Sites" design is really superfluous, really looking for a time to replace the MT4. Today finally hands, modified by the community converted OpenMelody . System and the installation process is basically the same with MT4, and a few file names have been changed, nothing difficult.

Part of the article is the first export in the old station to do, and then import the new system to do. Format is completely interlinked nature.

In addition to a large sign in the glare of the screen is purple, the little place is not pleasing to the eye.

Although the three languages have written some, but I'm more familiar with Perl programming language, Perl programming language I 』『 clarify the following ... XD

If the reading of the code module on CPAN, you will find out that Perl code is not write-only, but will become a write-only small, mostly to address the problem of low reproducibility, together with you especially like to take this part of the for discussion, and Perl has long left everyone down to the bias Bale. (Of course there are many, but not in this to mention)

Most of Perl programmers do not write write-only programs, but we all like to obfuscated the perl code that is out to show off, which is why the origin of one of the write-only.

However, if the other hand, who did not write write-only the code? In fact, everyone has written the code write-only experience, does not have to Perl for the job, right? :-P

In addition, the development of a long history of Perl, Perl has a proud unit test system, it is important to fully tested modules will be installed on your system, so even if a write-only do not have to worry about whether because of write- only cause other extension problems.

Incidentally, one question in recent years, the development of Perl, there are many modules have made the development of early modern Perl and Perl and has been a big difference. However, because most people's understanding for Perl is not much, so for Perl, we are still stuck in writing CGI 』『 that era. For example, Moose, Autobox module development, Perl can be made into post-modern object-oriented systems, allowing Perl to use more simple, powerful and easily extensible object-oriented features. The AnyEvent, Plack and other Perl modules also makes the development of the Web to develop more powerful and faster.

Relevant information about this can refer to gugod the good evils in perl (http://www.slideshare.net/gugod/good-evils-in-perl)

And the Moose: http://www.iinteractive.com/moose/

Plack:

cpansearch is a CPAN module search tools to write C formed. Provide a simple and fast way to search the module to function, and the ncurses to build a choice to install the interface module (class aptitude), can one choose to install a module to install. No other settings using cpansearch CPAN or CPANPLUS can be used directly.

, unable to bear cpan and cpanplus search speed (each index reload + update over at least more than 5 seconds), so find time to write with a cpan module C search tools. 'Cpans':

Blog in the Perl community to see this issue :

Consider a word (well, invented one): noogoo. Now, consider you want to do all possible combinations substituting oo with aa, that is, generate naagoo and noogaa.

In other words, write a function, let it eat three string input: s, x, y. And make it return a collection of content that is: there will be around s in substitution for the x-y combinations. A string substitution, there are permutations and combinations, is an interesting topic.

Thought of a recursive solution:

 #!/usr/bin/env perl use 5.010; # Combinatory Substitution Generator # cs(s, x, y) #=> () #   := s, if x is not in s #   := cs(s', x, y) + map { sp + $_ } cs(sx, x, y), otherwise #        where s' = s with the first occurence of x replaced with y #              sp = substring of s from the beginning to the first character of first occurence of x #              sx = s with sp removed sub cs { my ($s, $x, $y) = @_; return $s if index($s, $x) < 0; my $pivot_pos = index($s, $x) + 1; my $sp = substr($s, 0, $pivot_pos); my $sx = substr($s, $pivot_pos); substr($s, index($s, $x), length($x)) = $y; return cs($s, $x, $y), map { $sp . $_ } cs($sx, $x, $y); } say for cs("lady gaga", "ga", "gu"); 

Output such as:

 lady gugu lady guga lady gagu lady gaga

 #!/usr/bin/env perl use 5.010; # Combinatory Substitution Generator # cs(s, x, y) #=> () #   := s, if x is not in s #   := cs(s', x, y) + map { sp + $_ } cs(sx, x, y), otherwise #        where s' = s with the first occurence of x replaced with y #              sp = substring of s from the beginning to the first character of first occurence of x #              sx = s with sp removed sub cs { my ($s, $x, $y) = @_; return $s if index($s, $x) < 0; my $pivot_pos = index($s, $x) + 1; my $sp = substr($s, 0, $pivot_pos); my $sx = substr($s, $pivot_pos); substr($s, index($s, $x), length($x)) = $y; return cs($s, $x, $y), map { $sp . $_ } cs($sx, $x, $y); } say for cs("lady gaga", "ga", "gu"); 

Output such as:

 lady gugu lady guga lady gagu lady gaga 

Occasionally need a little exercise like this to prevent Alzheimer's ah ...

Perl 5.13.2, there is a change worth mentioning is the combined package block syntax.

 use 5.13.2; package Hello { sub world { "hello world" } } say Hello->world; # => hello world 

Grammatical structure like this is reminiscent of natural Java and Ruby's Class of. Or should be said that there are several object-oriented language ability, only about Perl syntax in the definition of special different namespace. In Perl 5.13.2 with other people after the same was. (Syntax like this seems to be some sort of industry-standard?) By the way, Perl's package not only the definition of Class only. Ruby to compare with the words, package is both a function of both Class and Module. For Perl programmers, the Class is used to define the package, is used to define Module package.

The feedback received from other modern languages, Perl syntax change also more every month a new development version is always released some amazing content. Perl's development is still more exciting was.
