Links to and fro. January 26 2011
  • Twitter can predict the stock market:
    “Measuring how calm the Twitterverse is on a given day can foretell the direction of changes to the Dow Jones Industrial Average three days later with an accuracy of 86.7 percent.”
  • Engineers hold our future in their hands.
    “Shortages of good engineers will define the limits of the economic growth of nations in the 21st century.”
  • Facebook is unnatural.
    “These are all pretty great ways to deal with this kind of news, but not at the same time. A Facebook discussion… would travel down several different paths simultaneously and I’d be stuck in the middle trying to participate with all subgroups in whichever way I normally interact with each. This has happened to me several times… It’s like being pulled in several directions at once, and the result is I just feel Facebook is completely useless for communicating with people.”
  • Mahalo 4.0: All about learning:
    “Jason Calacanis just gave a fun, very forthcoming overview of the history of Mahalo before describing its new mission: teaching stuff.”

Top 5 from the 17th+18th week: Typography, Data, Javascript

Because of my extended weekend in Berlin and at the seaside I did not put together my Link Digest last week, that’s the reason to look back to my top bookmarks of the last two weeks now.

Typography

  • The Golden Ratio Typography Calculator helps you to improve your website’s typography by entering your used font size, line-height, width, or characters per line (CPL). The math behind that tool is explained in The Ultimate Guide to Readable Web Typography.
  • Thinking with Type: Type is the foundation of print and web design. Everything you need to know about thinking with type, you will find here. This richly detailed update to the classic text belongs on the shelf of every designer, writer, editor, publisher, and client. (Jefferey Zeldman)

Data

  • Data Journalism Handbook: This collaborative book coordinated by the European Journalism Centre and the Open Knowledge Foundation aims to answer questions like: Where can I find data? How can I request data? What tools can I use? How can I find stories in data? How can I make data journalism sustainable? Provided under a Creative Commons Attribution-ShareAlike license you can read it for free as an early beta release, and if you want you may give feedback.
  • Linked Data FAQ: Structured Dynamic put together a document with some of the more prominent enterprise questions and answers regarding linked data. Linked data is the first practical expression of the semantic Web, useful and doable today, and applicable to all forms of data.

Javascript

  • Addy Osmani worte an article about JavaScript Style Guides And Beautifiers because “Following a consistent style guide both helps enforce this concept and improves the overall quality of the code we write. This facilitates other developers stepping in to assist with maintenance more easily and can certainly save time in the long haul. Readable source code is arguably easier for us to understand as well. It’s easier to browse, locate and fix bugs in and more easy to optimize. It can also give us a clearer picture of how the code fits into a larger body of work.”
6 from the 13th week: Web Accessibilty, Consumption, SASS/SCSS, Semantic Web statistics, WebID & Fake services
  • Web Accessibility Best Practices: Doesn’t matter if you are a beginner or a pro in the webdev area, this list is a good help and eye opener if you want to make your web projects accessible to everyone. Guys, this is important!
  • Nie wieder Fleisch?: This not directly related to webdev but our consumption and eating behaviour is related to our life and the the lives of all humans and animals. This documentary was shown on Arte TV, now you can watch it for a few days on their website. It’s about meat consumption and worldwide problems related to it. The movie is dubbed in french and german.
  • A Standard Module Definition for Sass: a very short tutorial on developing own SASS/SCSS modules, nonetheless it is a good introduction.
  • Web Data Commons: More and more websites have started to embed structured data describing products, people, organizations, places, events into their HTML pages. The Web Data Commons project extracts this data from several billion web pages and provides the extracted data for download. Web Data Commons thus enables you to use the data without needing to crawl the Web yourself. If you don’t want to dig into the data you simply can enjoy the statistics.
  • WebID – A Guide For The Clueless: Sebastian Trüg wrote a nice introduction and tutorial on WebID, another identity provider and authentication method that is based on a certificate in your browser and a relation to the responding public key in a public profile of you. You can get a WebID really fast without deep technical knowledge.
  • April Fools Days services and startups: I do not actively participate on April Fools Day anymore but I always like all the crazy ideas for fake startups and joke web services released this days like Google Voice for Pets, or - my favorite - the 8-bit version of Google Maps. Just check the April 1st edition of The Museum of Modern Betas (MoMB) (sorry, there seems not to be a direct link to the 4/1/2012 archive). Any other funny ideas out there?
Top 2 from the 19th week: Debian administration & RDFa

Spoken in links, it was a poor week. I’ve collected some links but it feels like only 2 of them deserve to be on my weekly top notch link digest list.

  • The Debian Administrator’s Handbook is written by Debian developers Raphaël Hertzog and Roland Mas, originally it started as a translation of their french book “Cahier de l'admin Debian” (Eyrolles). Traditional editors did not want to take the risk to make this translation, so they did it theirselves backed by a successful crowdfunding campaign. Now “The Debian Administrator’s Handbook” is finished, accessible online for free, and as paperpack and ebook through Lulu.
  • RDFa.info is a new starting point if you want to enrich your website content easily with semantic annotations about the things on your website. RDFa is an extension to HTML5 and HTML-like languages (e.g. XML, HTML4, SVG) that helps you markup things like People, Places, Events, Recipes and Reviews. Search Engines and Web Services use this markup to generate better search listings and give you better visibility on the Web, so that people can find your website more easily.
