WebAssemblyとBlazor 、WebAssembly System Interfaceでコンテナライズの設計を解説Takao Tetsuro
WebAssembly(WASM)とWebAssembly System Interface(WASI)は、コンテナライゼーションのアーキテクチャのひとつです。DockerやWSL(Windows Subsystem for Linux)と同じく、皆さんの業務ロジックにモビリティとスケーラビリティを与えてくれます。モビリティとスケーラビリティを考慮したプログラムを作る一例として、Rust、Nodeなどの技術を交えコンテナライゼーションを解説します。

This document discusses StyleStats, a tool for evaluating stylesheets. It provides metrics such as stylesheet and element size, simplicity, use of selectors, declarations, and other properties. StyleStats is used by Kaizen Platform in their styleguide. The document encourages signing up to work as a growth hacker with Kaizen Platform and thanks the reader.
Koji Ishimoto gives a presentation on front-end engineering. He defines a front-end engineer's responsibilities as including JavaScript, version control with Git, modular code, browser developer tools, command line, templating, CSS preprocessors, testing, automation, code quality and manuals. He discusses common front-end tools, managing tools with Grunt, and tracking speed with tools like WebPageTest to monitor performance. The talk aims to provide an overview of the front-end landscape and importance of performance.
- The document discusses the introduction and use of Sass and Compass for a large-scale e-commerce site.
- Key aspects covered include using Sass features like nesting, mixins, extends and @import to organize CSS, Compass features like sprite generation and creating a style guide.
- The results of adopting Sass/Compass included improved development speed and a 40% increase in site traffic over 4 months.
tissa is a simple timer app for iOS. There are absolutely no unnecessary buttons; it is simply an application devoted to marking the passage of time. The main font was created from scratch for this application. In addition to the timer function, there is a clock and a stopwatch, for a total of three modes, each of which can be easily switched with a swipe.
Using Google Analytics with jQuery MobileKoji Ishimoto
The document is a presentation on using Google Analytics with jQuery Mobile. It discusses how jQuery Mobile is a framework for building mobile websites and applications.

Communities of Practice – kanazawa.js結成までの軌跡 -Koji Ishimoto
This document discusses communities of practice and how to cultivate them. It outlines the key elements of communities including domains, members who participate at different levels from the core group to outsiders, and shared practices. It then provides examples of JavaScript communities that have formed in recent years including their activities, frequency of meetings, and growth over time. The document concludes by emphasizing the importance of champions, documents, and reciprocity for sustaining communities.
The document discusses improving web performance through coding practices like using CSS sprites to reduce HTTP requests, combining stylesheets and scripts, and implementing CSS3 features for browsers that support them. It recommends techniques like optimizing images, minimizing wait time through better server configurations, and prioritizing page load speed in website design. The presentation provides examples of how to measure page load times and analyze where time is spent using tools like HTTPWatch.
The document summarizes performance data from various websites including Google, Bing, Yahoo, AOL, Shopzilla and Netflix. It shows how website load times and speed impacted metrics like searches/user, page views, conversion rates and other key performance indicators. Faster sites experienced increases in desirable metrics while slower sites saw decreases. Credits and sources are provided for the different charts and data.
The document discusses high performance web design. It covers measuring performance using tools like YSlow and PageSpeed, as well as techniques to improve performance such as reducing HTTP requests by combining scripts and stylesheets, using CSS sprites, and inline images. The document also discusses how performance impacts businesses and provides examples of component weights and grades for different websites according to YSlow rules. It emphasizes the importance of clear objectives, consistent design, and clean code for building high performance sites.
