sketching | convert a picture to sketch by html5 canvas | Canvas library

I'm trying to make to make my first website with html and css (and js later). I want to make a calculator with a dropdown menu, but I'm struggling to make the dropdown menu as when it is hovered over, the dropdown list covers the menu.

To make a widget draggable, it has to be passed to a Draggable like so:

Actually I am using ArcGIS API for JavaScript 4.7 and i have a custom internal layer . I want to get name of place particular area when draw polyline the column name is (PLC_NAME) . How to achieve that ? Suppose I draw a area through polyline. In this area there are places . Now I need to get name of these places .

you can find the using code in below i am using the TileLayer.

I am sketching a small C++ program that will pass arrays to Lua and have them modified there, where I intend to have a lua script read in the program so I can modify it without needing to recompile the program

My first obstacle is to ensure Lua is able to modify arrays already allocated instead of having them allocated again in the Lua space. The data will be float and the size will be really large, but I am starting small for the moment.

To simplify this interface I tried LuaBridge 2.6, but it doesn't provide the expected result. Below is a fully "working" program.

I have a dataframe in R of data look likes this:

and I want to transform the table to this

What is the fastest way to do it in R?

Here is how I did it, but I admit that it's very long

Bear with me, it's a tricky question and what resources I've found around don't really help me resolve my problem.

I'm trying to build a real estate-oriented app on Kotlin. It must show at some point a RecyclerView with multiple object classes (say: houses, flats, plots, buildings, etc.)

I've seen multiple examples of RVs designed to accept multiple classes, but I'm struggling to put together a DB and the intermediary classes translating between tables and POJOs.

So far I've figured the following:

• I must have a Properties table that stores the unique ID for every object, along with another identifier for its type and a series of values common to every property (say, address, price, etc.)
• I must have a table for each entity type that can be independently listed as a real estate item (say, a house, a flat, a plot of land, a building, what have you). Each row on those tables will have a primary foreign key referencing its equivalent on the Properties table.

Now for the unexpected habanero. I decided to start sketching out my project on the basis of the RecyclerView Kotlin codelabs Google put together for newbies like me. Therein data is retrieved from the DB in this fashion:

this.plots = Transformations.map(database.RealtorDao.getPlots()) { it.asDomainModel() }

This works smoothly enough when the objects on the list the DB spits at you are all of one single kind, but what happens if you need them to be of different classes so that the adapter can tell them apart?

Or the only way around is just to build a gigantic table with about a hundred columns that will have nulls everywhere, and sort out objects ONLY AFTER they've been parsed in the previously described fashion?

i have seen a lot of documentation about normal distribution and curve sketching in python and i am a bit confused about it, i Have generated normal random variables with mean 30 and standard deviation 3.7 , and using function norm.dist i have estimated pdf function

I'm trying to make an example based on this pen I got from here: https://codepen.io/conradolandia/pen/YzyPmrv

But I want to use vue-router, I've tried this: (pen: https://codepen.io/conradolandia/pen/vYNERPW)

I draw a custom Tab-bar using Flutter's CustomPaint Widget it looks like this:

In Addition, this is the code I used to draw the widget :
