1. The document discusses the state of Ruby and Rails in Japan, noting that while Rails conferences exist internationally, there is no major Rails-focused conference in Japan.
2. It explores why Rails may be seen as "English software" in Japan and argues that the community needs to translate more materials to help globalize Ruby.
3. The author advocates getting more Japanese Rubyists involved in open source contributions to help spread Japanese Ruby innovations worldwide and integrate the local community with the global one.
Asakusa.rb is a Ruby community based in Asakusa, Tokyo that meets weekly on Tuesdays. It was started in 2008 and includes several famous Rubyists among its members. The group hacks on Ruby-related projects and also holds social events like parties. It aims to have fun while improving Ruby and bringing more happiness to the global Ruby community. The conclusion encourages growing similar local Ruby groups and visiting each other's communities.
The document discusses an NES emulator written in Ruby called Optcarrot. It aims to achieve 60 fps in Ruby 3.0 to drive optimization of the Ruby interpreter. The emulator currently runs at 20 fps in Ruby 2.0. It then details how the emulator achieves 20 fps through techniques like emulating the CPU and GPU in parallel and pre-rendering screens. Benchmark results are shown for different Ruby implementations, with JRuby 9k the fastest. Various "ProTips" are discussed to further optimize the emulator towards 60 fps through techniques like method inlining and replacing instance variables with locals.
Uncertainty Awareness in Integrating Machine Learning and Game TheoryRikiya Takahashi
This document discusses integrating machine learning and game theory while accounting for uncertainty. It provides an example of previous work predicting travel time distribution on a road network using taxi data. It also discusses functional approximation in reinforcement learning, noting that techniques like deep learning can better represent functions with fewer parameters compared to nonparametric models like random forests. The document emphasizes avoiding unnecessary intermediate estimation steps and using approaches like fitted Q-iteration that are robust to estimation errors from small datasets.
Presentation material for TokyoRubyKaigi11.
Describes techniques used by H2O, including: techniques to optimize TCP for responsiveness, server-push and cache digests.
IoT Devices Compliant with JC-STAR Using Linux as a Container OSTomohiro Saneyoshi
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.
