[PYTHON] A script that keeps looking up until the URL is bookmarked with Hatena Bookmark

If you write an article on your blog, do you ever want to find out if it's bookmarked? I have. That's why I made a guy who checks until a new bookmark is added and then alerts me when a new bookmark is added. Now you don't have to reload your browser. You did it!

However, notify is limited to Ubuntu, so Mac people should rewrite it appropriately.

def user_loop():
    url = sys.argv[1].replace('http://', 'http://b.hatena.ne.jp/entry/')
    print "Checking ->", url
    previous = None
    while 1:
        html = urllib.urlopen(url).read().decode('utf-8')
        soup = BeautifulSoup(html)
        user = int(soup.find('ul', {'class': 'users'}).find('span').text)
        if previous is None:
            previous = user
            continue

        if previous != user:
            os.system('notify-send -u critical "Bookmarked" "%d users"' % user)
        previous = user
        time.sleep(600)

    print "Polling -> ", url
    while 1:

        if html.find(u'This page has not been bookmarked yet.') == -1:

        popup = "[%s]<br />" % (datetime.datetime.now().isoformat())
        popup += "Try again after 5 minutes."
        os.system('notify-send -u low "%s" "%s"' % (title, popup))
        time.sleep(300)
