In my JavaFX project I'm using a lot of shapes(for example 1 000 000) to represent geographic data (such as plot outlines, streets, etc.). They are stored in a group and sometimes I have to clear them (for example when I'm loading a new file with new geographic data). The problem: clearing / removing them takes a lot of time. So my idea was to remove the shapes in a separate thread which obviously doesn't work because of the JavaFX singlethread.

Here is a simplified code of what I'm trying to do:

HelloApplication.java

I have an ASP.Net Webforms website running in IIS on a Windows Server. Also on this server is the SQL server.

Everything has been working fine with the site but now I am seeing issues with using a DataAdapter to fill a table.

So here is some code, please note it's just basic outline of code as actual code contains confidential information.

I need to group rows in a dataset based on a rowwise comparison or matching of four different variables in a way that it can be computed fast. The dataset has the following shape:

Specifically, I would like to group those rows that share the same value in either start<>end, end<>start, start<>start, or end<>end and have a matching value (>0) in the related start_sep and end_sep column. start_sep and end_sep are basically an additional check if the first match is correct. Groups usually contain matches of two rows, but can be of any number in size if a rows start and end matches more than one. Matches are always unique, so there won't be a matching conflict of two rows with the same matching start and end combination.

Here is a little illustration of potential match combinations in the columns 'start' and 'end':

For the example above, the expected result would be:

In this sense matches can occure within a row

I can do this with a slow for loop and a set of conditions, ie., selecting a row (if group_id is NA) finding all matches (based on conditions describing possible match combinations) and asign group_id. But since my dataset has 1 million plus rows, this is a very slow process. See below an example for a single case example below:

I am building a Create a Recipe form using crispy forms and I am trying to use a datalist input field for users to enter their own ingredients, like 'Big Tomato' or select from GlobalIngredients already in the database like 'tomato' or 'chicken'. However, regardless of whether I enter a new ingredient or select a pre-existing one, I am getting the following error: "Select a valid choice. That choice is not one of the available choices.". How do I fix this error?

I am working on a personal project with NextJs and TailwindCSS.

upon finishing the project I used a private navigator to see my progress, but it seems that the stroke is not working as it should, I encounter this in all browsers except Chrome.

Here is what i get :

Here is the desired behavior :

Code:

I am trying to build an SVG something similar to:

The strokes are completely dynamic, as they come from an API. I want to place the strokes at the points received (as array of percentage values). Need not be in order and the distance between 2 strokes need not be equal

I am trying with something like below but not able to come up with a logic for the placement of strokes. I tried to follow the answer here: https://stackoverflow.com/a/66076805/6456247 but the distance between strokes here are equal. In my scenario, they are not consistent.

I have an input range in a div contained in an outer div that is smaller than the inner div. The final result is that my inner div scrolls horizontally (because the outer dive has overflow: scroll), and the input range is its child.

To customize the range, I removed the appearance in CSS with appearance: none. Now, here is what happens. When I check it in Chrome developer's tool (actually I use Brave, but I'm guessing it is the same in Chrome as I tested in Chromium, and it is the same) with the smartphone option active, 99% of the time if I try to move the range handle it moves the whole div with it. Now, if I disable the smartphone option, it works just fine. Also, if I keep the smartphone option and remove the appearance: none from CSS, it also works just fine, but my customizations to the range disappear. Does anyone know what is going on?

PS.: in Firefox, the input range doesn't work as long as I keep the smartphone option on (no matter if I have the appearance property or not).

Here is an animated gif of what I mean: First, I have the described above with the input range with no appearance. It works fine, I can move the scrollable div and move the input range handle independently. Then I put the appearance: none to the input range (notice the formatting of the input range changes), now I can't move the input range handle independently from the scrollable div anymore. Finally, remove the appearance from the input range, and everything goes back to normal (but my customizations are gone)

Here is the code, but you can only simulate by using the developer's tool with the smartphone option active, where you can simulate the touch.

In a standard create-react-app configuration, there’s a third-party component that I can import when needed:

I am trying to remove jcenter() from my project because it is deprecated. But I am using com.google.android.libraries.places:places:2.4.0 dependency that is currently the latest version, that is outlined in official docs. And interesting thing, that when I try to build project it fails, because it can't find dependency com.android.volley:volley:1.1.1. I do not use this dependency in my project directly, but I found, that it is transitive dependency inside places library.

When I execute gradlew app:dependencies I can see such situation:
