V mware
Robbie Jerrom presents on Puppet, an open source configuration management tool. Puppet takes a declarative approach, allowing users to define what a system configuration should be rather than how to achieve it. Everything in Puppet is defined as a resource like packages, files, and services. Puppet uses a client-server model to manage configurations across multiple systems from a central Puppet master. It provides an easier way to deploy and manage software compared to traditional scripting approaches.

From Zero to Hadoop: a tutorial for getting started writing Hadoop jobs on Am...
Hadoop is everywhere these days, but it can seem like a complex, intimidating ecosystem to those who have yet to jump in.
In this hands-on workshop, Alex Dean, co-founder of Snowplow Analytics, will take you "from zero to Hadoop", showing you how to run a variety of simple (but powerful) Hadoop jobs on Elastic MapReduce, Amazon's hosted Hadoop service. Alex will start with a no-nonsense overview of what Hadoop is, explaining its strengths and weaknesses and why it's such a powerful platform for data warehouse practitioners. Then Alex will help get you setup with EMR and Amazon S3, before leading you through a very simple job in Pig, a simple language for writing Hadoop jobs. After this we will move onto writing a more advanced job in Scalding, Twitter's Scala API for writing Hadoop jobs. For our final job, we will consolidate everything we have learnt by building a more sophisticated job in Scalding.

It then outlines possible POCs for Hadoop distributions, ETL/analytics frameworks, performance testing, and developing a scaling layer. The goal is to contribute open source code and help with Capital One's transition to using Hadoop in production.
ZendCon 2015 - DevOps for Small Teams
Joe Ferguson discusses how small development teams can implement DevOps practices. He recommends using version control for all code and configurations, developing on the same environments that are deployed (using Vagrant), implementing continuous integration and testing, and automating common tasks through aliases, scripts, and cron jobs. The talk provides many specific tools and resources for setting up version control, continuous integration, testing, and automation for small teams.

Common boolean class_for_perl5
The document discusses the lack of a standard boolean class in Perl 5 and proposes two new candidates - bool.pm and Types::Bool - to address this issue. It provides background on how booleans are typically implemented in Perl 5 without a native type, challenges with existing solutions, and why a standard boolean class would help with serialization and interoperability. The bottom line is that any new solution needs to work well with existing Perl modules.
萬國之津梁
This document summarizes Kenichi Ishigaki's presentations and activities related to Perl conferences from 2016 to 2018.

Better detection of what modules are used by some Perl 5 code
This document discusses Perl::PrereqScanner::NotQuiteLite, a module that detects which modules are used by Perl 5 code in a more accurate way than existing tools. It summarizes that Perl::PrereqScanner::NotQuiteLite can detect module requirements across a wide range of frameworks and syntax, including Moose, Catalyst, and Test::More. It also migrates the detection of module requirements from Perl::PrereqScanner to Perl::PrereqScanner::NotQuiteLite and describes how to update CPAN files and test them based on the module usage detected.
Json(::PP) is a-changing
This document discusses recent changes and improvements made to the JSON and JSON::PP Perl modules, including fixing various issues, adding better and faster number detection, incremental parsing, and UTF-16/32 support in an experimental capacity. It also notes that specifying PERL_JSON_BACKEND=Cpanel::JSON::XS should now work properly and that a few incompatible changes may have been introduced between JSON::PP and Cpanel::JSON::XS.
2016年のPerl (Long version)
Perl 5.24 was released in 2016 with several notable changes including hashbang redirection to Perl 6, removal of autodereferencing, and performance enhancements. Perl 6 development progressed with the release of the Christmas roast specification tests and Rakudo becoming more stable on MoarVM while work continued on implementations for other platforms like JVM and JavaScript. The Perl community continued to enhance CPAN and develop new features for Perl 6 like TWEAK submethods and lexical module loading.
JSON, JSON::PP, and more
This document summarizes recent changes and features of the JSON and JSON::PP Perl modules. It discusses changes made to address issues, add experimental features like incremental parsing and UTF-16/32 support, and loosen validation of the PERL_JSON_BACKEND setting. It also provides examples of sorting hash keys during encoding and converting values during decoding. Remaining unimplemented features like validating Unicode characters and supporting newer JSON standards are acknowledged.
What you need to remember when you upload to CPAN
Perlのモジュールを公開するときに気をつけておいた方がよい個のこと
This document provides tips for publishing Perl modules to CPAN. It discusses things to be aware of such as distributions being permanently archived on BackPAN even if deleted, CPAN accepting almost anything, and several testing services that can improve modules like PAUSE, CPAN Testers, CPANTS, and more. It also covers best practices for metrics evaluated by these services around availability, integrity, file layout, prerequisites and more. Developers are encouraged to use better tools from the Perl Toolchain Gang to avoid issues.
On UnQLite
UnQLite is an embedded key-value and document-oriented database with a simple API similar to SQLite. It uses a BSD license and supports cross-platform usage. Benchmarks show it has comparable or better performance than SQLite, Berkeley DB and other databases for common operations like storing, fetching, and iterating over large amounts of data. The developer is working on adding new storage engines to UnQLite.
typemap in Perl/XS
This document discusses extending Perl with C libraries using XS. It explains that XS provides an interface between C and Perl by handling data conversion between their different types. The document outlines the components of a basic XS file and how it is compiled. It also discusses typemaps which define how C types are mapped to Perl types to allow values to be passed between the languages. Further details are provided on developing the XS interface and common tools like h2xs and a new converter tool.
Annual Report 2012
This document appears to be an annual report from 2012 that includes:
1) A welcome from Kenichi Ishigaki and information about YAPC::Asia 2012.
2) Lists of the top 10 qualitative Japanese authors for 2012 and statistics on new CPAN authors in Japan and worldwide from 2000-2012.
3) Charts showing trends in the number of releases by Japanese authors, worldwide releases, active authors in Japan, and active authors worldwide from 2000-2012.
4) A thank you message at the end.
DBD::SQLite
This document summarizes Kenichi Ishigaki's presentation on DBD::SQLite recipes, issues, and plans at YAPC::Asia 2012. The presentation covered:
1. Ten recipes for common SQLite tasks like bulk inserts, in-memory databases, table alterations, database attachments, hooks, unicode, and custom extensions.
2. Ten issues and plans for the DBD::SQLite module, including debates around the default transaction mode, refactoring the execute method, optimization efforts, and compatibility with different compilers and platforms like iOS.
3. Questions and suggestions from the audience were welcomed on improving recipes, resolving issues, and advancing plans and roadmaps for DBD::SQLite.
CPANTS: Kwalitative website and its tools
- Kenichi Ishigaki created a list of Japanese CPAN authors and a script to maintain it since there was a need to more easily track Japanese authors.
- He launched a website, acme.cpanauthors.org, to feature CPANTS info but it had no data since the official CPANTS site was down. He set up his own private repository to store the data.
- Work is still needed on CPANTS including adding tests, making the processing faster, fixing broken metrics, and integrating more external data sources. The tools and resources are now in place to continue improving CPANTS.
CPANTS 2012
CPANTS is the CPAN Testing Service that tests Perl modules on CPAN to ensure quality. It runs 24 core tests plus 10 extras on modules to check issues like extractability, strict pragma use, POD documentation tests, dependency on other modules, and more. The tests help attract attention to quality problems. CPANTS data is now mirrored at cpants.charsbar.org since the original site was not being maintained. The speaker has been refactoring the mirror and adding improvements like renewed module metrics and queries. Future work includes faster testing, better UI, and JSON API.

- 7. cpanmetadb
- 9. It usually doesn't download indices from a CPAN mirror.

- 17. We can guess.
- 18. We have CPAN testers.
- 19. They continuously do comprehensive tests.
- 20. It might be reasonable to trust them and skip tests.
- 21. Go a step further.
- 22. You delegated testing to the testers.
- 23. Why don't you delegate building to someone else, too?
- 24. You can use system package managers like yum or apt.
- 25. It's convenient if you are satisfied with official packages.
- 26. It might cause lots of troubles if you install private packages without care.

- 28. PPM
- 30. PPM is a tool to install pre-processed packages.
- 31. Originally written for ActivePerl.
- 32. Used largely by the Windows users.
- 33. Not only for Windows.
- 34. 60-70% of the CPAN distributions are ready for PPM.
- 35. You could save more time if you use them.
- 36. Or, if you can use them.
- 37. PPM has gone through several turning points.
- 44. PPM2 client cannot parse metadata for PPM4.
- 45. We need a new client.
- 46. Fortunately, the spec is simple.
- 47. So I wrote one.
- 49. Not released to the CPAN yet.
- 50. Now we can install 60-70% of the CPAN more quickly.
- 51. Then, what to do with the rest?
- 52. The most fundamental remedie is fix them.
- 53. Or, you can package what you want by yourself.
- 54. Creating PPM packages is very easy.
- 56. You can also use a dedicated module.
- 57. PPM::Make
- 58. $ make_ppm
- 59. You might also want to provide a summary file.

- 64. He also created yet another CPAN search site called kobesearch.
- 65. Or CPAN::SQLite
- 66. Or Pod::Perldocs
- 67. He passed away last year.
- 68. I'm not sure until when his repository would be kept.
- 69. I took over some of his modules, and started preparing kobesearch mirror.
- 70. (not done yet)
- 71. Found several things to fix.
- 73. Have you ever tried WebStart?
