See the original post<\/a> for the basic information. This post exists only to highlight a few bug fixes.<\/p>\n

Since running with my sign for a few days, the main bug I’ve run into is that Twitter doesn’t let you post identical status messages over a short period of time. One recommended fix is to append some sort of unique data to each message<\/a>. So I’ve decided to<\/p>\n

    \n
  1. Convince my browser to append a millisecond time value to each message, and enclose the value in curly braces. So a status message of “In office” becomes “In office {339}”, for example.<\/li>\n
  2. Modify the Python script to strip out the millisecond value so it doesn’t show up on the door sign. We’ll use a regular expression to filter out any pair of curly braces surrounding 1-3 digits.<\/li>\n<\/ol>\n

    Updated code is below the break.<\/p>\n

    <\/p>\n

    Page of Twitter Status Bookmarks<\/h1>\n

    Links are now of the form<\/p>\n

    <a href=\"javascript:void(0)\" onclick=\"gotostatuspage('In office'); return false\">In office<\/a>\n<\/pre>\n
    and the gotostatusurl() Javascript function is added to the page header<\/p>\n
    <script type=\"text\/javascript\">\n\u00a0 function gotostatuspage(message) {\n\u00a0 \/\/ Navigate to the status page, append a pseudo-random number to\n\u00a0 \/\/ trick Twitter into letting us post the same status message\n\u00a0 \/\/ repeatedly.
