ghastly | A spectogram generator in Rust | Generator Utils library

Have a look at my NUFOSMATIC site for viewing UFO Sightings from the National UFO Reporting Center. I put this together some 17 years ago (I'm sooooo old) using a simple-minded approach on a webserver provided by the ISP that did not have any way to serve anything more than HTML, Javascript, and Java applets. It does the job for me.

A couple of years ago (ok, 6 years ago) I was burned (along with everybody else) by the mess that Oracle made of Java. I spent a little time migrating the site's features from Java applets and my primitive maps from publicly available data to OpenLayers and OpenStreetMap. Very kuel. Got some new stuff out of it, but I lost a few things, too.

I've recently been upgrading the maps to OpenLayers 6. My original implementation was OpenLayers 2, and they managed to completely re-write the API with OpenLayers 3, and I finally found time to get my head wrapped around it and just do the work. Four days to migrate from ol2 to ol6! And I actually got back some of the functionality I had with Java applets.

So before I deploy I'm looking for other things I might... modernize... in the code. I find now that frameset/frame is "obsolete" - I also find that there is NOTHING in HTML5 that works like frameset/frame.

Note most of the site I've looked at say "obsolete" and NOT "deprecated" - it sounds like something that gonna disappear just as soon as they think nobody's looking...

Basically, I have four frames: the "corner", the "header", the "menubar", and the "main". As you move from one site feature to another, managed from the "menubar", the HTML in the "main" frame is replaced. The single page gives a place to save some session-global values (like which year and month you're looking at).

Back with a couple of SwiftUI layout questions :

I'm trying to display 2 lists side by side with custom cells. I created the cell views (EventRow.swift) and I display them in my content view.

I added a border to my lists, for better visibility.

As you can see from the picture below, the result is ghastly:

I would like the gradient effect to be applied to the whole cell, width and height wise.
I tried setting the frame of my EventRow (using .infinity for width and height), but this crashes the app.
Since the size of EventRow is inferred, I also don't know how to adapt my row cells height to its size : you can see the horizontal delimitating bars are not fitted to my custom EventRow...

If anyone has some pointers for this, it would be greatly appreciated.

The sample project can be found here

But I also post my code below:

ContentView :

I'm trying to write a slider that has logarithmic scaling to control a microphone RMS threshold.

I have written the function below that may be ghastly (maths is not my strong suit) but does seem to do the logarithmic scaling that I want. However, I now need to display the RMS level in a bar that uses the scale, so I need to invert this function.

How can you delete a Document with all it's collections and nested subcollections? (inside the functions environment)

In the RTDB you can ref.child('../someNode).setValue(null) and that completes the desired behavior.

I can think of two ways you could achieve the desired delete behavior, both with tremendously ghastly drawbacks.

1. Create a 'Super' function that will spider every document and delete them in a batch. This function would be complicated, brittle to changes, and might take a lengthy execution time.

2. Add 'onDelete' triggers for each Document type, and make it delete any direct subcollections. You'll call delete on the root document, and the deletion calls will propagate down the 'tree'. This is sluggish, scales atrociously and is costly due to the colossal load of function executions.

Imagine you would have to delete a 'GROUP' and all it's children. It would be deeply chaotic with #1 and pricey with #2 (1 function call per doc)

Thanks for checking out this post, I appreciate it!

Apologies I am aware of the clean ups that are being done on redundant posts from newbies so I hope I've provided information that is the most relevant!

I have been having issues with a "Intervention \ Image \ Exception \ NotReadableException Image source not readable" issue with Laravel for the past day with the code that's flagged, being -

This is about filling a background with a color.

I am building a SwiftUI version of this project. It's a tabbed app (test harness).

This is my Working Project

The first thing that I'm doing, is setting the tabs up. I expect to be learning a lot, and hitting a lot of walls.

The first wall, is that I fill the app background with a (ghastly) virulent green background gradient.

This takes the form of a stripe that I stretch horizontally.

With IB, not an issue.

With SwiftUI, I need to figure it out.

Here's the code I have so far:

I am writing a Slack bot using Dialog flow. I'd like to respond to a fulfillment request using Slack blocks. Unfortunately, whenever I include blocks in my response, my bot stops working.

Here's what I've have now:

I've tried looking at a few other questions with vaguely similar problems but am yet to find a solution.

So just setting up a very basic web page, just for testing/messing. You can find it here https://gogglebot.net/test/test/ I'm unable to include a MWE as stripping it down to just the header makes it function fine so I'll put the entire thing at the end.
I make no apologies for the ghastly colour nor default font.

I've got a header and then 2 left floated divs as a sidebar then main body. At some point a horizontal scroll bar appeared and I have no idea why. In my attempt to fix it I tried setting everything up to < html > to be 100vw.

I am still lost as to what's going on, putting it back together piece by piece shows me that its the sidebar that for some reason fulfils its birthday wish to become wider, but I have no idea why this would cause this. The sidebar + main body are smaller than 100%. I found some code from another question that checks for elements above the viewport width and it returned nothing. From Chrome's inspect tools I cannot see anything that's too large, just the 100% width header extends beyond the screen.

Weirdly, if I set the sidebar to be 100%, it also overextends to the same amount, but it still says its 1366px wide which is the expected value (laptop)

Getting the same result in Edge.

I can't seem to find a question on this, but I'm having issues maintaining PEP8 because of a module I've imported.

I'm using the TextGridTools (tgt) module to parse TextGrid files, format for annotating spoken audio files. The problem is it has functions with ghastly long names such as get_annotations_between_timepoints.

Because I'm using it inside a class method with loops, conditionals, and a list comprehension, it's already significantly indented:
