Microsoft has announced that it will be closing its DRM-encumbered ebook store, with the consequence that its customers' ebooks will "no longer be available to read".
I don't buy ebooks with DRM (nor anything else with DRM, for that matter), but apparently lots of people do, and many seem to be content - even proud - to buy ebooks with weak DRM, which they expect to be able to remove.
I don't do that, and I'd urge anyone that does to reconsider.
To obtain a Let's Encrypt certificate, you have to prove that you control the domain name(s) the certificate will cover. The simplest and most common way to do this involves placing a special file at a special URL on your website, which Let's Encrypt then checks by making a HTTP request to your server on port 80. Most popular ACME clients such as Certbot can easily automate this domain validation method.
Unfortunately, this doesn't work in the case where port 80 is closed.
I received your materials outlining your priorities for Seanad Éireann and was dismayed to learn that you advocate "online voter registration and voting".
Voting in Seanad Éireann elections is at present conducted by means of a postal ballot. Postal voting already presents a variety of serious threats to the confidentiality and integrity of the ballot. Online voting would solve none of these problems, exacerbate most of them, and introduce some new and unique problems of its own.
