progressively | A JavaScript library to load images | Frontend Framework library

The use-case is that I want the user to be able to preview a song hosted at a remote URL. Fine, you say, just use AVPlayer. Yes, but I want to be able to cache the file locally if it is completely downloaded in the course of being previewed. As far as I can tell, there's no way to access the local data that AVPlayer downloads for its streaming playback. Likewise, there's no way to get access to the data being downloaded by URLSession until it is completely downloaded. So, I'd like to find a result using one of these approaches:

1. Access the data in AVPlayer once it has completed downloading it and save to a file.
2. Download the data progressively to the cached URL and have AVPlayer play it as enough data becomes available.

Are either of these scenarios possible? Is there some other scenario which will achieve what I am looking to do?

What I'm looking to do is take an array of numbers which progressively get bigger determine the highest one I can round down to. I'm not sure if that makes sense, I will give an example. Keep in mind I am making the numbers more simple for the sake of explanation, removing the last digit wouldn't work. The array I am using has 100 numbers going into the millions.

I would like to know if it is an anti-pattern to create nested context providers (the same context) and progressively extend the data. So, using the current context and enriching/overriding it from that point downward.

Are there obvious (not to me yet) disadvantages to this approach ?

Is there relevant terminology for this that i might be missing, in order to search for more info ?

I am building a sort of ABAC system for a product. This access can be affected by different items which are available for a specific item.

I have following simple Isabelle/HOL theory:

I’m wanting to do successive animations, like one after another instead of on a loop or one at a time. What does it look like when coding that?

Example: fade in @ 100% opacity, then fade out @ 20% opacity, then fade in 80%, then fade out 10%... so like a pulsing then at 0% change the label text and do the inverse (basically the same as the picture only every time I try and make it progressively fade out- it disrupts the whole animation)

The gif shows it's current state, not what I've tried thus far that didnt work.

I'm trying to build a view that is a rounded rectangle in a bar chart, with a gradient that gets progressively darker the higher value is (value is on a 0-10.0 scale). But I can't seem to figure how how to use UnitPoint here for endPoint to get the correct point where the gradient should end. In other words if value = 5.0, I want the gradient to show the top of the bar as half way to the gradient's darkest color, or said another way the gradient's darkest color is always at 10.0 and the bar's color will only show as high as the bar is.

I've generated a unique list of strings. Each string is 6 numbers separated by a colon. The list of strings has been sorted from largest to smallest by the first number then progressively by 2nd, 3rd, and so on. Example snippet below:

I hope this message finds all of you well. I have been working on a macro to make entomological specimen labels that come with an embedded QR code such that museum curators can scan the QR codes of a series of specimens in the same group and easily manipulate their data. The QR code images are inserted as "shapes" (I believe--they respond to shape commands in the macro), and are generated via the brilliant pure-VBA script by Jiri Gabriel, with editing by Jonas Heidelberg (https://github.com/JonasHeidelberg/barcode-vba-macro-only). The basic premise of the macro is that it takes some data, populates a bunch of cells with strings and values (i.e., what gets printed on the human-readable part of the individual labels), and then when all of the printed text is inserted, the macro iteratively generates one QR code image at a time and places each generated image next to the corresponding human-readable label.

The issue I'm running into is that the macro is quick to generate and insert the first few QR code images, and then gets progressively slower, and slower, and slower with each successive image--I presume because Excel is not built to handle a large number of high-resolution images on the same spreadsheet. My current sheet design accommodates 220 individual QR code images, but it takes nearly 10 minutes just to populate the spreadsheet with 50 QR code images (on the other hand it takes less than 30 seconds to populate with 10 QR code images, so the slowdown is appreciable).

Is there something I can do on the macro end to make the process not run so slowly? Things I have tried are as follows:

1. Disable screen updating - does not seem to improve the processing speed

2. Set calculation to manual - does not seem to improve the processing speed

3. After generating each QR code image, hide the image by using the following code, and then at the very end, turn all the images visible - seems to help a little bit but not nearly sufficient to make the macro usable at scale.

   ActiveSheet.Shapes.SelectAll

   Selection.ShapeRange.Visible = False

I've looked for solutions to see if all of the QR code image shapes can be merged into one shape, because after all, wouldn't it be easier to manage a single shape than 200+ individual small shapes? But alas there seems to be no functionality to combine all of the shapes into a single shape. Another solution I had thought about is if the macro can simultaneously generate all of the QR codes at once, instead of iteratively, then perhaps it won't have the issue of the later-coming shapes being so slow to render due to having to hold all of the previously rendered codes in its memory. But I haven't found a way to write the code such that all QR code image shapes are generated in parallel, rather than in sequence. Yet another solution I toyed with is to paste the shapes as PNG or some other image that could potentially be easier to deal with, but I get a lot of loss of quality, which seems strange because the QR code should be just a matrix of black and white cells, right? Why do they lose so much quality?

At any rate, any advice would be greatly appreciated! Thank you so much in advance!

EDIT: Thank you so much @Алексей-Р for the very helpful answer! Looks like I will upgrade my version of Excel... :)

I already have panning and zooming for my map program, as well as markers, but the zooming code I currently have works sporadically and doesn't feel natural. It seems as though it gets progressively worse the further from the center of the map you are. I've been trying to achieve a zoom similar to that seen in Google Maps, with little luck.

This is the current zooming code:
