2022-11-07: we have gotten a notification that we have an overage for our
tracking and I'm pretty sure this has to do with Workbench usage.
Considering that I am not _currently_ using this tracking because I do not
yet know how to access the data, I am turning this off for now.
<script>
var _paq = window._paq = window._paq || [];
/* tracker methods like "setCustomDimension" should be called before "trackPageView" */
_paq.push(["setDocumentTitle", document.domain + "/" + document.title]);
_paq.push(["setDomains", ["*.preview.carpentries.org","*.datacarpentry.github.io","*.datacarpentry.org","*.librarycarpentry.github.io","*.librarycarpentry.org","*.swcarpentry.github.io", "*.carpentries.github.io"]]);
_paq.push(["setDoNotTrack", true]);
_paq.push(["disableCookies"]);
_paq.push(['trackPageView']);
_paq.push(['enableLinkTracking']);
(function() {
var u="https://carpentries.matomo.cloud/";
_paq.push(['setTrackerUrl', u+'matomo.php']);
_paq.push(['setSiteId', '1']);
var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
g.async=true; g.src='https://cdn.matomo.cloud/carpentries.matomo.cloud/matomo.js'; s.parentNode.insertBefore(g,s);
})();
