Friday, November 21, 2025 Good morning sports fans! # I'm continuing to work on the way FeedLand detects changes in feed items. This morning I did a careful study of the function that gets a guid for an item in conjunction with ChatGPT. It would be so much easier if RSS 2.0 required an item-level <guid> element, but it doesn't. That was the philosophy, all item-level values are optional. My notes are here . # Linkblog items for the day Trump gives Mamdani warm reception. theguardian.com I beg to differ. The reason Mozilla replaced MSIE to the extent that it did is that Microsoft wasn't doing anything about the malware that came in through their browser. blog.mozilla.org rssCloud pings emanating from self-hosted WordPress site. github.com Harvard Law School Library releases first complete set of digitized Nuremberg Trials records. hls.harvard.edu How billionaires took over American politics. wapo.st ...

Thursday, November 20, 2025 I'm working today in the internals of FeedLand, specifically the code that determines if an item has changed. When we check a feed, we check each item, if the item already exists, we look at each of the values stored for the item compared with their new values in the feed, and if any have changed, we broadcast the message that the item has changed. I'm doing a complete review of this, based on actual data, and found there were a fair number of places we were calling a change, when nothing that mattered had changed. Now I'm debating whether or not a pubDate change should be seen as an item change. My initial thought when we were working on RSS, was that the pubDate should never change. In the real world of publishing I don't think the publication date changes. Right? Of course some feeds do change the pubDate because that's the art of feeds (sorry for the sarcasm). But I don't think FeedLand should call that a ch...

Wednesday, November 19, 2025 If Bluesky and Mastodon were "on the web" they would already interop because friends that's what the freaking web does. They behave like closed off silos, and until that changes, they can't claim to be on the web. Don't sell out the web so cheap. It really means something to be on the web. # One of the reasons Mastodon doesn't get credit for being "on the web" is that there's been no buzz about the ActivityPub support in WordPress. Ghost has been beating the drum about their ActivityPub support for (many) months. I don't know if they're actually there yet, I've never knowingly seen something from Ghost on Mastodon. I sent an email to Matt this morning suggesting that we promote the incredible connection between WordPress and Mastodon via ActivityPub. In the early days of the blogosphere we had the same problem, there was no good way to see who was writing, so we started a site called ...

Tuesday, November 18, 2025 Highly recommend this week's conversation between Nicolle Wallace and Heather Cox Richardson. The contrast of their points of view is dramatic, the election wasn't a win for the Dems, it was a victory for the people. # I'm looking into the problems in feedlanddatabase I mentioned yesterday. I bet it'll turn out there are a bunch of issues that have been there for a long time, but don't show up in the user interface of the product. I'm still developing good techniques for debugging Node.js server apps. Recently, I've developed new tools that make these bugs show themselves, like socketdemo . I added some new capabilities to it in the JavaScript console that make the updates visible. If you open the console in the debugger while it's running you'll see what I'm talking about, screen shot . Sometimes to debug a problem that doesn't have a UI you have to give it a UI. # BTW, one of the areas of...

Monday, November 17, 2025 The Lever podcast does have an RSS feed . A good way to find the feed when the usual hacks don't work is to post it here , where it's a matter of pride for the braintrust to dig it up. Thanks as always. 😄 # Over the weekend I flipped the switch on a new app that makes my blog available on WordPress. It seems to work really well. The WordPress site is Daveverse . And because it's on WordPress it is also available on ActivityPub, at @scripting@daveverse.org, which means you can read it on Mastodon. It doesn't feel weird at all to be reading a blog post on a social network. I posted on Bluesky that we would love to have the same connection with their social network. It might happen sooner than you think. There are people developing writing tools for ATProto, but they're kind of stuck since Bluesky has all those limits that exclude the writer's web . It's so complicated, but out the other end, I hope will come a...
