QueryList | progressive PHP crawler framework | Crawler library

I hope to get data from a sealed class Result, but val mydata = queryList.data cause the following error, how can I fix it?

Error Information Smart cast to 'Result.Success>' is impossible, because 'queryList' is a property that has open or custom getter

I have multiple dynamically created Angular tables, each displaying the same columns but with different data. I need to sort the columns in each table separately. I currently have two tables. When I click on the column header arrow on the first one, it sorts correctly. Clicking on the same column in the second table does nothing.

Here is the relevant html:

I'm new to angular. I've been trying to sort columns but I keep on getting this error:

Argument of type 'Event' is not assignable to parameter of type 'SortEvent'. Type 'Event' is missing the following properties from type 'SortEvent': column, direction - ngtsc(2345).

Any suggestions on how to make this work?

i am trying to use an IntersectionObserver in my Angular application but it doesn't work as expected. I don't have a reproducible example as this affects a productive implementation, maybe this simple case might be enough. So i have a view that generates certain elements via the *ngFor directive:

app.component.html

I have a table and I want to pass HTMLElement of the table cell to the component via click event hadler. At the very begininng I have the pointer to the correct table cell but after I init change detection manually the pointer points to the wrong cell (the next to the correct one)

I can't find out why it happens. I created example with console.log(tableCell) before and after initialization of the change detection (method setEditMode in AppComponent)

I have an Angular project and I'm trying to define a variable with the following type:

I have a dataframe containing 6.3 million records and 111 columns. For this example I've limited the dataframe to 27 columns (A-Z). On this dataframe I am trying to run an analysis in which I use different combinations of the columns (with pairs of 5 columns per combination) and subset each of those on the dataframe and do a count of the number of occurrences for each combination and finally evaluate if this count extends a certain threshold and then store the combination. The code is already optimized with an efficient way of running the individual subsets, using numba. But still the overal script I have takes quite some time (7-8 hours). This is because if you use for example 90 columns (which is my actual number used) to make combinations of 5, you get 43.949.268 different combinations. In my case I also use a shifted versions of some columns (value of day before). So for this example I've limited it to 20 columns (A-J 2 times, including the shifted versions).

The columns used are stored in a list, which is converted to numbers because it otherwise gets to big using long strings. The names in the list corresponds with a dictionary containing the subset variables.

Here is the full code example:
