Static Site Generators Static Site Generators Group 2 Reinhard Egger, Daniel Geiger, Lorenz Leitner and Peter Oberrauner 706.041 Information Architecture and Web Usability WS 2019/2020 Graz University of Technology 02 Dec 2019 Abstract Static Site Generators are tools to automatically create fully-fledged HTML web pages that can be served statically to each client with no need for regeneration. In an age of per-client dynamically created web pages, static web pages offer a valuable alternative, the benefits of which are discussed in this survey paper. The way in which Static Site Generators work and what technologies they use is described, as well as how content can be rendered on the web in general. An overview of the most relevant Static Site Generators and their features is given, although not all can be mentioned due to the sheer number of Static Site Generators in existence. A concluding recommendation for people looking to choose a tool suited to their liking is provided as well. © Copyright 2019 by the author(s), except as otherwise noted.

Before static site generators existed, web developers wrote HTML web pages by hand, which is time-consuming and does not adhere to the Don’t Repeat Yourself (DRY) principle, as much of the HTML code is essentially the same, most often only differing in content, while the structure code necessary for the page setup remains the same. 1.1 Basics Static site generators take care of much of the leg work web developers used to have to do. Only the content and some optional metadata need to be entered manually, the surrounding HTML code is created.

  • Mobile Site Rewrite
    Mobile Site Rewrite Patrick Reilly — Senior Developer Mobile Wikimedia Foundation Current implementation ● Ruby based mobile gateway utilizing Merb Process: ● A request comes in from a mobile browser ● The request generates a Device object in merb/extensions/request_extension.rb ● The Device object picks a format in Device#format_name ● Any method_missing that Device receives is looked up in the format specification ● The formats are specified in config/formats.yml ● An Article is fetched for that device ● First, the article figures out what kind of parser needed to be run on the page It then generates a key with that parser type. ● It then checks to see if that has been cached ● If it is not cached, it grabs scrapes the Wikipedia page and processes it with some /app/models/parsers/* class ● If it is cached, it returns that cached object ● The layout is generated with the returned Article#html ● The device format is used heavily here (aka, "= current_device.stylesheet_name") ● An "app/views/layouts/search#{format}.html.haml" file is rendered in the search area ● Changes in the search box and CSS fields are the biggest difference between formats Mobile site rewritten in PHP ● Having the site in Ruby causes a number of headaches (for code review, code deployment, and server maintenance) given Wikimedia's mostly PHP-based infrastructure. Rewrite rationale ● Puts the code in our code repo rather than on github ● Easier to review code in a language that most Wikimedia/MediaWiki developers are already using (PHP, instead of Ruby) ● Easier on

TOMÁŠ VOJNAR, Ph.D. VEDOUCÍ PRÁCE BRNO 2016 Abstract The aim of this thesis is to research the differences between the CSS preprocessor languages, namely Less and Sass, and find applicable transformation methods to implement a converter between their dynamic stylesheet formats. A general introduction to the concept of CSS preprocessors is provided first, which is followed by a thorough description of the Lessand Sass language features. In addition to this, all the discovered differences are stated and illustrative examples of the invented conversion methods are provided in this work. This is followed by the description of the design and implementation of the proposed converter. As a part of the contribution of this thesis, a CSS comparison tool based on abstract syntax tree transformation has also been developed. Its design is described along the testing procedure used to verify the invented conversion methods. The last part of the work summerizes the achieved results and the future directions of the converter. Abstrakt Cílem této bakalářské práce je výzkum rozdílů mezi CSS preprocesorovými jazyky, jmen- ovitě Less a Sass, a nalezení použitelných transormačních metod k implementaci překladače mezi jejich formáty.

    Transport Area Working Group M. Amend Internet-Draft D. Hugo Intended status: Experimental DT Expires: 13 January 2022 A. Brunstrom A. Kassler Karlstad University V. Rakocevic City University of London S. Johnson BT 12 July 2021 DCCP Extensions for Multipath Operation with Multiple Addresses draft-amend-tsvwg-multipath-dccp-05 Abstract DCCP communication is currently restricted to a single path per connection, yet multiple paths often exist between peers. The simultaneous use of these multiple paths for a DCCP session could improve resource usage within the network and, thus, improve user experience through higher throughput and improved resilience to network failures. Use cases for a Multipath DCCP (MP-DCCP) are mobile devices (handsets, vehicles) and residential home gateways simultaneously connected to distinct paths as, e.g., a cellular link and a WiFi link or to a mobile radio station and a fixed access network. Compared to existing multipath protocols such as MPTCP, MP- DCCP provides specific support for non-TCP user traffic as UDP or plain IP. More details on potential use cases are provided in [website], [slide] and [paper]. All this use cases profit from an Open Source Linux reference implementation provided under [website]. This document presents a set of extensions to traditional DCCP to support multipath operation. Multipath DCCP provides the ability to simultaneously use multiple paths between peers. The protocol offers the same type of service to applications as DCCP and it provides the components necessary to establish and use multiple DCCP flows across potentially disjoint paths. Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.
