  • 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.









  • As a guy responsible for a 1,000 employee O365 tenant, I’ve been watching this with concern.

    I don’t think I’m a target of state actors. I also don’t have any E5 licenses.

    I’m disturbed at the opaqueness of MS’ response. From what they have explained, it sounds like the bad actors could self-sign a valid token to access cloud resources. That’s obviously a huge concern. It also sounds like the bad actors only accessed Exchange Online resources. My understanding is they could have done more, if they had a valid token. I feel like the fact that they didn’t means something’s not yet public.

    I’m very disturbed by the fact that it sounds like I’d have no way to know this sort of breach was even occurring.

    Compared to decades ago, I have a generally positive view of MS and security. It bothers me that this breach was a month in before the US government notified MS of it. It also bothers me that MS hasn’t been terribly forthcoming about what happened. Likely, there’s no need to mention I’m bothered that I’m so deep into the O365 environment that I can’t pull out.





  • Upvotes and downvotes.

    Right now, I can browse by New on my subscribed communities and see every post since the last time I did that.

    I can view or re-view posts and read every response. If the responses are legion, I can play with hot/top and get the meat of the discussion.

    Did you notice that last sentence? On the few posts where there are too many responses to view all, I’ll try to get at those that are relevant.

    If the Lemmy community grows large enough, I’ll need to do the same for posts. I will no longer be able to regularly view by new and have time to see everything.

    So, I’ll need to rely on some sorting method to make certain I see relevant stuff.

    Someone with millions of bots that never post have millions of upvotes and downvotes to influence the score used by the sorting algorithm that I’ll use to decide what to read.





  • I migrated to Reddit after Digg imploded. Here’s a few things I think were better.

    Feeds weren’t filled with meme posts. Comments weren’t filled with quick one-liners to get upvotes. Back then, there was much more substantive commentary.

    Now, over the years, I’ve subscribed to subreddits that contained the type of content I wanted, plus the default subreddits I was subscribed to as a new user back then are much different than today. Open Reddit using a different browser or a private browser window, so that you’re not logged in. How does that compare to your experience of 12 years ago?

    Honestly, much of the things I don’t like are because of large entities wanting to influence social media. That same thing will happen (likely is already happening) to the fediverse. I just hope the distributed nature makes it more difficult.


  • I’ll agree and go one further: the idea of wanting to recreate Reddit is bad.

    Most of us left Reddit because of the API crap, but I suspect most of us have not been as happy with the Reddit experience as we once were. The more you recreate a system that’s close to Reddit, the more you make it easier for influence campaigns, spam bots, and disruptive trolls to operate.

    Federation, with separate but similar communities, makes it tougher for a massive bot operator to run a monolithic influence campaign. My hope is the design of the fediverse helps to defend against these types of attacks. My fear is the inexperience of server operators with these types of coordinated attacks makes it difficult.





  • 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.
