ViewText extracts article content from web pages, text from PDF’s, and reformats RSS feeds to include the full article text for each RSS feed item. The idea spawned from the frustration of viewing overly complex web pages on mobile phones. To counter this, I created ViewText and a simple API for third party sites to pull the main content from web pages and display it in an easily readable format.
iHackerNews is a mobile version of Y Combinator's Hacker News. It was created to address deficiencies in Hacker News when viewed on mobile devices. For this, I scrape the HTML from Hacker News, extract the relevant pieces, and optimize it for mobile phones, specifically iPhone and Android devices. Data is cached to prevent unnecessary requests. For actions that require user authentication, I retrieve the user’s authentication token by proxying credentials between the client device to my server, then from my server to Hacker News, and finally retrieve the authentication token from the issued cookie. The authentication token is then sent along with HTTP requests when voting or commenting on the site.
ToadJaw is a bookmarking service that indexes, tags, archives, and displays your bookmarks. Its main purpose is to store content you wish to keep and make that content easily findable, even if the content is removed from the original source. ToadJaw is built on ASP.NET MVC, SQL Server, and Lucene. It's currently in active development and in closed beta.
