I have three classes for Dog, Bird, and Cat. Each is almost the same. Without consolidating into one class of Pet - is it possible to choose from a list of pets, and then call that class? I am getting an error right now:

I'm working on Laravel Framework 8.73.2 project with mysql Ver 8.0.26-0ubuntu0.20.04.3 for Linux on x86_64 ((Ubuntu)).

I'm getting wrong data from the database when using the offset condition. On the third data request I get unique data, but on the fourth data request I get repeated data

third data request, offset = 20

I'm using a Scanner for a file example that's got 4 boys and 3 girls. After each name there is an integer (for instance Mike 24) and it starts with a boy then girl then boy then girl etc. In total there are 4 boys and 3 girls and I'm supposed to count the number of boys and girls and then add up each boys numbers for the sum then the same for girls. Also, when I assigned boys the console.nextInt() does that take the number from the file and then assign to the boys variable? Also, does console.hasNext() have an index like if it reads token #1 then I can say console.hasNext() == 1;?

Sample data:

I have a working code that successfully obtains all product links from multiple pages that have at least a 20% discount. The only problem is that it returns links in the arrays for each page separately. However, I would like it to return links for all pages in a single array and then transfer them to another function. I tried to create a string var all_links = [] and push all the links from each page into it and then return them like return all_links, as I know from a simpler example. However, I have not been successful in this case because I have no experience with coding. I started learning the basics three weeks ago. I would be very grateful if you could help me with the whole code as I don't have the necessary prior knowledge.

Hi there, I am attempting to build a WebRTC client in Android that subscribes to a video feed that is being broadcast using NodeJS and JavaScript.

The broadcaster code can be viewed in its entirety in this lovely article by Gabriel Tanner.

It works beautifully when running it in localhost under the http://localhost:4000/broadcaster.html in Chrome and then visiting my IP Address from another device on the network. I can see the video and it is near real time.

I have tried this using two different webcam devices, both a built-in and a USB webcam but the Android client does not work even though the JavaScript Broadcaster and Client works fine.

After following the tutorial and getting the example to work I decided to try and implement my own Android application for which the entire source code can be viewed right here on my GitHub.

I have followed various tutorials around the place and the issue always stems from attempting to set the remote description which is done with the following bit of code:

I don't understand why this happens:

I would like to reshape a file but the typical use of reshape doesn't apply to my problem (I don't think). I could do this by hand but it would be error prone and I wouldn't learn how to use R to accomplish this. So after reading about Reshape and Tidyr, I decided to come here.

I have a file of electrical utilities and the counties in which they operate. I want to be able to reshape it so that it is a list of counties and what electrical utilities operate within them. I also have a variable for whether I have data for each utility in another dataset called "InData". Then I will determine on this basis what is the degree of missingness for each county.

The column names are: UtilityName, InData, County1,County2,County3,County4... County12

Is there a simple way to reshape this or do I need to create some kind of loop going through each column?

Here is and example of the data:>
