I'd like to create polygons with st_voronoi and merge them by a variable

I would like to add a 'clear' button to a DatePicker from @mui/lab (5.0.0-alpha.55).

What I am attempting:

• Store a date field in state, passed as the value prop to DatePicker
• Change the date to null when desired to 'clear' the value & input

The behaviour I observe:

• If the date is valid, it works as expected, and the input is cleared
• If the date is not valid, the error is cleared, but the invalid date still stays in the input.

The rudimentary version I have attempted which shows the behaviour above can be seen here.

If you input a partial date, then click clear, you can observe that the input does not get cleared.

I would prefer to avoid a solution that involves changing the key, as that brings other issues, such as not respecting an external source changing the date to null, and needing additional hacks to respect the label transition when clearing the input.

Suppose we have the function y = x^2, we could plot this continuous function from x=0 to x=100 like so:

I have a Python3.9 / Quart / Hypercorn microservice which runs in a conda environment configured with an environment.yml file. The base image is continuumio/miniconda3.

It took a lot of hacks to get this launching because of conda init issues etc.

Is there a cleaner way to get a conda environment installed and activated within Docker without having to resort to conda run commands and override the default SHELL commands?

What is the simplest, most readable and straightforward way to raise an illegal instruction in RISC-V on purpose?

I know that per spec any "full zero" instruction (so 32/16 bits only zeros) is a "Defined Illegal Instruction" (section 12.5, user spec). But I have no idea if there exists an asm shorthand for that (at least I could not find any) that I could then use in inline asm in C code.

There must surely be a portable and reliable way to always cause an illegal instruction exception? I personally find writing to read-only registers or similar hacks quite offputting, as they are not very explicit. But maybe this is just how its done?

Thank you in advance

Suppose I have the following code:

I am using build-push-action in Github Actions (with buildx) to build Docker image and push it to AWS ECR registry. Before I push the image (unfortunately, it has several GB), I want to use the image to run containerized Python tests.

build-push-action has docs on this exact goal - their example suggests to build the image, load it to Docker, use docker run ... and then push. However, while it takes 7 minutes to build the image (from downloaded cache), it takes another 7 minutes to load it to Docker - so it is doubling the time of the CI pipeline. The example from docs:

How can I add the iconbutton at the end of the text like this ?

I use Row widget but the iconbutton is not in the right place, it is not at the end of the text

This is my code:

I'm using Vaadin Deisgner 14.6.1 to create some super simple tabs. However, when I try to do some simple operations in the java class (eg selecting a tab), it throws an error which indicates that the "Tabs" object does not have the proper children "tab" components. Here's a simple test case below. (I discovered the issue when I was trying to add a addSelectedChangeListener() to the tabs class and discovered that it would never fire, presumably since the "tabs" class never properly had any children.) I tried a bunch of hacks, but nothing worked. (I have in the past gotten tabs to work if I stuck purely to a programmatic approach, but I really really really like using Designer, since it saves me tonnes of times and keeps the code quite modular and clean....when it works....)
