    The person isn’t talking about automating being difficult for a hosted website. They’re talking about a third party system that doesn’t give you an easy way to automate, just a web gui for uploading a cert. For example, our WAP interface or our on-premise ERP don’t offer a way to automate. Sure, we could probably create code to automate it and run the risk it breaks after a vendor update. It’s easier to pay for a 12 month cert and do it manually.



  • Except it’s not that they are finding the expansion rate is different in some directions. Instead they have two completely different ways of calculating the rate of expansion. One uses the cosmic microwave background radiation left over from the Big Bang. The other uses Cepheid stars.

    The problem is that the Cepheid calculation is much higher than the CMB one. Both show the universe is expanding, but both give radically different number for that rate of expansion.

    So, it’s not that the expansion’s not spherical. It’s that we fundamentally don’t understand something to be able to nail down what that expansion rate is.


  • And the article content posted is just an excerpt. The rest of the article focuses on how AI can improve the efficiency of workers, not replace them.

    Ideally, you’ve got a learned individual using AI to process data more efficiently, but one that is smart enough to ignore or toss out the crap and knows to carefully review that output with a critical eye. I suspect the reality is that most of those individuals using AI will just pass it along uncritically.

    I’m less worried about employees scared of AI and more worried about employees and employers embracing AI without any skepticism.








  • Yep. I’ve hosted my own mail server since the early oughts. One additional hurdle I’d add to you list is rDNS. If you can’t get that set up, you’ll have a hard time reaching many mail servers. Besides port blocking, that’s one of the many reason it’s a non-starter on consumer ISP.

    I actually started on a static ISDN line when rDNS wasn’t an issue for running a mail server. Moved to business class dsl, and Ameritech actually delegated rDNS to me for my /29. When I moved to Comcast business, they wouldn’t delegate the rDNS for the IPv4. They did create rDNS entries for me, and they did delegate the rDNS for the IPv6 block. Though the way they deal with the /56 IPv6 block means only the first /64 is useable for rDNS.

    But, everything you list has been things I’ve needed to deal with over the years.
