Odyssey to async ruby
•
2 likes•218 views
This document summarizes Delton Ding's journey developing an asynchronous Ruby web framework called Midori. It discusses how Ruby can be slow due to blocking I/O, and how Midori aims to solve this using fibers and an I/O pool to enable non-blocking code. Benchmark results show Midori outperforming Sinatra for a basic web server and database workload. The document outlines Midori's goals and middleware-focused architecture, and proposes next steps to improve I/O, add clustering, and provide scaffolding.

High Concurrent Ruby Web Development Without Fear
This document discusses high concurrency Ruby web development. It begins by stating the goals of defeating other languages like Erlang while maintaining easy Ruby-like usage. It then shows benchmarks demonstrating Ruby's relative slowness. An approach using EventMachine callbacks is presented, but noted to be difficult. An asynchronous library called Midori is introduced, which uses fibers to avoid blocking and achieve performance comparable to Node.js. Middleware, real-time communication, and next steps are briefly discussed before concluding.
Rockit: A Parser Generator for Ruby
Discusses Rockit, a parser generator for the Ruby langauge. Touches on versions 0.3.8 and 0.7.2, which are GLR and PEG, respectively. Describes GLR and PEG. Given for http://www.cs.rit.edu/~ats/lp-2006-2/
Special Subject 1+2: RoR 2
Ruby on Rails is a web application framework that is an alternative to PHP and allows for human-oriented programming. The presenter developed a Snort Log Monitor in Ruby that took 3 weeks but had annoying behavior and small community support. Going forward, Rails could be used to brainstorm potential projects like a blog, online shop, or Snort webGUI.

IronPython combines the best of Python and .NET by allowing Python code to run on the .NET framework. Microsoft developed IronRuby and IronPython which implement Ruby and Python respectively on .NET. These dynamic languages are supported by the Dynamic Language Runtime (DLR) which provides a common environment for dynamic languages to run on .NET.
Perl 7, the story of
The story of the big public discussion happened in the beginning of 2013 about the future naming of the Perl programming language.
IronRuby for the Rubyist
IronRuby is a Ruby implementation that compiles Ruby code to .NET Intermediate Language. It allows Ruby code to run on the .NET Common Language Runtime and interoperate with .NET libraries. IronRuby was started by Microsoft but is now an open source project. It enables Ruby developers to build applications that integrate with existing .NET systems and libraries. However, IronRuby is still missing support for some Ruby standards like OpenSSL and has a lower test passing rate than MRI Ruby.
Perl 5.16 and beyond
Perl 5 is evolving rapidly with new stable releases being produced more frequently. The vision is to allow Perl 5 to continue evolving while maintaining backwards compatibility. This may involve externalizing features into modules, allowing different versions of Perl semantics based on version declarations, and moving to saner defaults over time through longer deprecation cycles. The goal is to keep Perl 5 a useful and sustainable language.

3. The document also provides resources on functional decomposition, abstract data types, object-oriented design, and troubleshooting services.
Ruby Introduction
Ruby is a multi-paradigm programming language that is object-oriented, imperative, and reflective. It was created by Yukihiro Matsumoto, also known as "Matz", and was influenced by languages like Perl, Python, Smalltalk, and Eiffel. In turn, Ruby has influenced other languages like Swift, Groovy, Rust, Julia, and D. Ruby is cross-platform, uses file extensions like .rb and .rbw, has a huge community, and is easy to learn and read since it does not require semicolons.
Agile Graduation Using Ruby
Lightning Talk @ RubyConf Taiwan, 2011.
This is a brief introduction of what I've done in
my Graduate School, NCCU.
Due to this is a 5 mins talk, I've omit lots of technical
detail and focus on what this topic can possibly, even slightly influence Ruby developers.
If you're interested by this topic, please let me know and we can have more discussion.
The story of language development
The document summarizes aspects of developing and maintaining the Ruby programming language, including its core team members, development resources, issue tracking process, testing procedures, release management, and security practices. The Ruby core team consists of around 90 committers and branch maintainers who work on various parts of the codebase. Development resources include build servers, documentation hosting, package distribution, and funding from various sponsors. Feature requests require use cases, attached patches, and approval from the project leader Matz. Releases aim to occur yearly on Christmas and follow a branch model with backported fixes. Security issues present ongoing challenges.
Inside GitHub with Chris Wanstrath
This document provides an overview of GitHub and its technical architecture presented by Chris Wanstrath. Some key points:
- GitHub started as a git hosting site but became a social coding platform where users can see friends' activity and leave comments.
- It uses Ruby on Rails for the main codebase, Resque for background jobs, MySQL for the database, and nginx, unicorn, and memcached.
- Git operations are handled by Grit and communicated to file servers via the BERT-RPC based Smoke protocol.
- Caching, asset optimization, and AJAX loading are used extensively to improve performance. Monitoring tools include Nagios, Resque Web, Haystack, and CollectD.

PyData Frankfurt - (Efficient) Data Exchange with "Foreign" Ecosystems
As a Data Scientist/Engineer in Python, we focus in our work to solve problems with large amounts of data but still stay in Python. This is where we are the most effective and feel comfortable. Libraries like Pandas and NumPy provide us with efficient interfaces to deal with this data while still getting optimal performance. The main problem appears when we have to deal with systems outside of our comfort ecosystem. We need to write cumbersome and mostly slow conversion code that ingests data from there into our pipeline until we can work efficiently. Using Apache Arrow and Parquet as base technologies, we get a set of tools that eases this interaction and also brings us a huge performance improvement. As part of the talk we will show a basic problem where we take data coming from a Java application through Python into using these tools.
Gemification for Ruby 2.5/3.0
Future of Ruby standard libraries will focus on gemification. Standard libraries will be extracted out of the Ruby core repository and maintained as default gems or bundled gems in GitHub repositories. This allows libraries to be updated independently of Ruby releases and more easily accept contributions. While this approach has benefits, it also has challenges around maintaining compatibility and complex dependencies. The process of gemification will be gradual to reduce the size of changes.
Metaprogramming in Ruby
This document discusses metaprogramming in Ruby. It begins by mentioning Lisp and how Ruby can think like Lisp through metaprogramming. It then discusses creating languages from scratch or using tools like Bison/yacc/lex. It recommends learning from languages like Lisp, Scheme, Forth and Smalltalk that pioneered metaprogramming techniques. The document discusses how metaprogramming allows code to be treated as data through techniques like self-modifying code and dynamic adding/removing of classes and functions. It provides examples of metaprogramming in areas like web frameworks and AI. It discusses tools for metaprogramming in Ruby like operator overriding, open classes, method_missing, blocks and eval. Finally, it demonstrates

Free The Enterprise With Ruby & Master Your Own Domain
On the heals of Luis Lavena's RailsConf talk "Infiltrating Ruby Onto The Enterprise Death Star Using Guerilla Tactics" comes a local and frank talk about the current state of Open Source Software (OSS) participation from Windows developers. Learn what OSS is, what motivates its contributors, and how OSS can make you a stronger developer. Be prepared to fall in love with writing software again!
We will start off with a 101 introduction to both the Ruby programming language and the Ruby on Rails web application framework. You will learn about ActiveRecord, a powerful ORM that maps rich objects to your databases, and the latest components to use it with SQL Server. As a Rails core contributor and author of the SQL Server stack, I will give you a modern insight into both that will allow you to leverage your legacy data with Ruby.
Lastly, I will review the bleeding edge tools being actively created for Windows developers to ease the transition to Ruby, Rails and OSS from a POSIX driven world. Many things have changed. It is time to learn and perform some occupational maintenance.

Suzanne Lagerweij - Influence Without Power - Why Empathy is Your Best Friend...
This is a workshop about communication and collaboration. We will experience how we can analyze the reasons for resistance to change (exercise 1) and practice how to improve our conversation style and be more in control and effective in the way we communicate (exercise 2).
This session will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
Abstract:
Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdf
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

Carrer goals.pptx and their importance in real life
Career goals serve as a roadmap for individuals, guiding them toward achieving long-term professional aspirations and personal fulfillment. Establishing clear career goals enables professionals to focus their efforts on developing specific skills, gaining relevant experience, and making strategic decisions that align with their desired career trajectory. By setting both short-term and long-term objectives, individuals can systematically track their progress, make necessary adjustments, and stay motivated. Short-term goals often include acquiring new qualifications, mastering particular competencies, or securing a specific role, while long-term goals might encompass reaching executive positions, becoming industry experts, or launching entrepreneurial ventures.
Moreover, having well-defined career goals fosters a sense of purpose and direction, enhancing job satisfaction and overall productivity. It encourages continuous learning and adaptation, as professionals remain attuned to industry trends and evolving job market demands. Career goals also facilitate better time management and resource allocation, as individuals prioritize tasks and opportunities that advance their professional growth. In addition, articulating career goals can aid in networking and mentorship, as it allows individuals to communicate their aspirations clearly to potential mentors, colleagues, and employers, thereby opening doors to valuable guidance and support. Ultimately, career goals are integral to personal and professional development, driving individuals toward sustained success and fulfillment in their chosen fields.
