How The Web Works (Overview) - Continuations Tech Tuesday: How The Web Works (Overview) As promised at the end of last year’s Tech Tuesday, we are starting this year with a cycle on how the web works. Just as a reminder, Tech Tuesday’s aim is to require no previous knowledge other than what has been covered before. So this overview may be trivial for some readers but I wanted to make sure to bring everyone along. Let’s assume you have fired up your favorite web browser. What happens now? Step 1: The address “dailylit.com” is part of what is known as a URL. Step 2: The “dailylit.com” portion of the URL is the domain name (you can get your own from a domain registrar). Step 3: Now that the browser has an IP address, in the case of DailyLit currently 72.32.133.224, it makes a request to “GET” content from 72.32.133.224.

The Collabowriters - About About The Collabowriters is an experiment in creating a crowdsourced novel. Every line in the novel is drawn from a number of submissions from users, and voted upon by the community as whole. As such, the story is written and edited by anyone and everyone together, one sentence at a time. The project is an exploration of storytelling and the dynamics of group interaction. How It Works The novel is written one sentence at a time. Users, such as yourself, then vote on each submission, giving it a score of either +1 or -1. In order to proceed to the next sentence of the novel, one of the submissions in the current sentence must receive at least a score of 5. Creator The Collabowriters was conceived and created by Willy Chyr.
