You'd use the hx-delete attribute and have a server side handler that responded to that by deleting the item & returning a new list of items. You can see an example of that approach (with Rust + Actix Web) here that I'm currently working on (the partial to list todo items is in templates, and you can follow the delete link to the relevant handler in routes/todo/delete.rs):
It appears that EURDEP (European Radiological Data Exchange Platform) data isn't being shared with the public at the moment. I'm not sure if this is because of the war, this attack in particular, or if they're having problems with their infrastructure due to people like me wondering what's going on.
Their simple map (https://remap.jrc.ec.europa.eu/Simple.aspx) shows the last update as being 03/03/22 22:00 UTC, but selecting a station doesn't give any current or historic readings.
I didn't follow any training plans to get up to the half marathon distance. Once I'd finished the C25K plan I decided to see what 10K felt like and it was ok... did a few of those and then tried 15K. At that point I figured I could do a half and entered one. Although I didn't follow a plan I do keep an eye on my GPS watch to see what pace I'm doing - if I'm planning a long run I'll hold back the pace from what I know I can run so I don't tire myself out.
I think training plans depend a lot on what you're wanting to do - I just wanted to complete the distance; I could probably do it faster with a proper training plan but I've found running without worrying about time (too much) to be enjoyable (and I have still got respectable results for my age).
I started with a C25K plan in November 2020 and ran my first half marathon in October 2021. I'm looking at marathons now, it's changed my level of fitness far more than I could imagine.
