Features (limitations)

A logged-in user sees a text-input field at the top of the page, which is used to post a message.

A post is limited to 300 characters with no formatting. It uses client-side JavaScript to post and display messages. The most recent 150 posts are displayed in reverse order, youngest to oldest.

JavaScript refreshes the page every 20 seconds. A logged-in user can refresh sooner by hitting the return key or tapping the post button. A user who is not logged-in can refresh sooner by tapping the refresh button.

The client-side JavaScript sends a POST request to the server. The server-side code sends only JSON data to the client-side JavaScript. This applies for the list of messages and for errors.

Testing as of Feb 28, 2014

  • Chrome - works
  • Firefox - works
  • Opera - works
  • It works in Opera Mini on an old flip phone, but the JavaScript code for the interval/auto refresh does not work. Have to click the post button to refresh page.
  • IE v8 - works when posting by tapping the post button, but nothing is posted when hitting the return key.
  • HP tablet with WebOS - works fine when tapping the post button, but when hitting the return key on the tablet screen, it double-posts.
  • iphone ?
  • Samsung S4 ?
