Wednesday 24 January 2018 receives a green padlock

This is just a little note to advise that my website,, now has a security certificate. This reassures visitors that all communications between their browser and the site are encrypted.

It also means that the url has changed to

Web browsers such as Chrome, Firefox and Internet Explorer display a small green padlock icon in the address bar to visually indicate that you have a secure HTTPS connection.

For a time, the old http:// url will automatically redirect to the https:// url, but I'm not sure for how long, so if you have bookmarks to the site, or you link to it in publications or online, please make a note of this change.

Meanwhile, the url of this blog,, does not yet have a security certificate. (Nor does any other custom domain url hosted on Google. Apparently Google is working on facilitating this, but again, I don't know how long it will take.) I'll let you know when it does.
