This probably ins't typical setup, but due to higher decisions we endup having multiple kafka clusters within one app, multiple topics per each, and each might have different serializing strategy. Json/avro. And avro might be with confluent schema registry or using single object encoding.

Well I got it working somehow, by building my own abstractions and registry which analyzes the configuration and creates most of stuff manually, but I feel I needed to repeat stuff like topic names, schema registry url on several places multiple times just to create all needed beans. Ugly as hell.

I'd like to ask, if there is some better way and support for this I just might have overlooked.

I need to create N representations of kafka clusters, configuring it once. Configure topics respective to given kafka cluster, configure confluent schema registry for topics where applicable etc, so that I can create instance of Avro schema file, send it to KafkaTemplate and it will work.

I am trying to stylize my form using bootstrap. As you know bootstrap uses a lot of classes in order to do what it does. By googling I have found to inject some new classes into my form I could use widgets with django. My form is as follows:

I'm looking at the Common Lisp HyperSpec and I don't see where the default test for MEMBER, FIND, and POSITION is specified. Am I overlooking something obvious?

Word on the street is that EQL is the default test, but I would feel more comfortable knowing that's in the spec somewhere.

I'm trying to migrate an existing, small Flutter app to Flutter 2.12. The null safety thing is new and still confusing to me. For the most part I have been successful in resolving the errors from the migration, but I haven't found a solution for this problem. Here we go:

I am attempting to write a code for Newton's Method for nonlinear systems in Python. My g function is a 5x1 matrix and the jacobian (derivative matrix) of this is a 5x5 matrix. The vector for the initial y values (y0) is also a 5x1. i keep on getting the error

I have a NodeJS API and I need to create an endpoint which creates a richly-featured dynamic PDF report and saves it to an S3 bucket. I've been working with PDFKit (https://pdfkit.org/) and have most of what I need from there, but I've come up across a stumbling block because the latest design I've been given includes a donut chart generated with eCharts and I can't figure out how to include this using PDFKit. It needs to be generated dynamically for each call. There is no visible HTML page which displays the report, this must all be achieved within the NodeJS API.

Are there any pre-existing solutions I'm overlooking that would make this possible?

NB I have some flexibility so it doesn't have to be specifically an eCharts solution, as long as I can include a stacked donut chart with labels.

Thanks.

I am trying to read a gz file into a char buffer which should resize depending on how big the file is.

I'm trying to parse an extension out of a list of files of the format 'filename.extension'. However in the cases where filename is blank, I'm getting undesired results.
