Glad to hear that you got it working! The hard part for me was to figure out how to transform a JSON string into an array of n8n objects. I had already done that before so now I just copy that node whenever I need something like again.
I’m doing a bit of tweaking
I figured you would have. But that is half the fun. :-)
Do you have a link? OOTL
were pretty eager with that trmove button for that.
Yeah, I only noticed that after it had been pointed out recently. I hope it didn't scare anyone away.
I had to implement drag and drop in a Windows application recently. Since you don't know the content type nor the size of the content, pointers has to be used, which makes sense. For the most part when working within the bounds of my own application, I haven't found a good use case for pointers. That could of course be because I am not used to thinking in that way.
Sharing a workflow requires a paid plan but could should be able to paste this in the editor to get the same effect.
I made two different sample flows, on that call the api and responds with directly with the response data (transformed). The other workflow is to same the data in a data table, and call the weather api on a schedule. You could even use ntfy and send notifications on a schedule if it will rain within an hour.
Edit the nodes to suite your need (URL, content of response etc).

Since you are using n8n, pull the data on a schedule and save it in a data table. Then create a webhook to serve the content as you want it. N8n can transform the JSON data, I can provide a sample tomorrow.
~~Have you tried running it but not exposing any ports using docker compose?~~ EDIT: Saw that it worked with 4443:443.
In addition, rule 7 (low effort posts) is deleted as everyone seems to agree its handled just fine with votes.
Completely agree with this one. I like to browse new and I'd rather keep the occasional low effort post than delete them. There are relatively few posts at it is.
I still don't get the point of pointers.
I want my language to pass by reference. I give a variable to a function and the variable in the function scope should be a reference to the same place in memory as the original variable.
How can pointers help me here? What value does it provide? Genuine question.
From article: Staff got worried, checked his house and no one answered. They called an ambulance (”medical services”) and he was taken to the hospital.
1% CPU usages, 50% RAM usage. That checks out.
I have to follow this now!
