Rover | The Rover Rescue System | 3D Printing library

I am new to swift and trying to figure out how to parse JSON to a struct. I am trying to get an image from NASA Mar's Rover Photos.I am trying to follow tutorials online, but can't seem to fix this issue. What am I doing wrong here?

error:

Fatal error: The data couldn’t be read because it isn’t in the correct format.

I am trying to make a get route for this API:

https://api.nasa.gov/mars-photos/api/v1/rovers/opportunity/photos?sol=1000&api_key=92Ll6nGuQhfGjZnT2gxaUgiBhlCJ9K1zi2Fv5ONn

And although the syntax for the get route, the API still doesn't work in postman nor in client-side.

Here's the get route code:

Whenever I am trying to compile my java project in netbeans IDE, I am getting these errors. Kindly, please help me through it. I have provided the whole source code as well. Thank you the error are given below. I am making a car parking system in java and my whole source code in written in java language

I am a beginner programmer looking to improve - I've made some pretty cool Python games with pyGame - and now found an interest in KIVY! The separation of logic and layout is great. But as a non-seasoned veteran in OOP, I am pretty much going crazy at this point. I don't know how to connect all the different parts. Most KIVY tutorials I can follow are basic and concentrate mainly on design - which is fine, but when it comes to putting real meat on the bones, there isn't much to go with.

(Then there are the ones that seemingly build GUI's for the Mars Curiosity rover - those are way over my head). I do grab bits and pieces of knowledge in the process, but my code, and my brain, ends up suffering from too many different approaches and programmer styles colliding together. [hopefully that makes some sense] I wonder if fundamentally I need to start from scratch and throw out bad advice?

In the code below I've set up a simple KIVY gui with two screens. Page one increments a variable "A", page two increments the variable "B". I am able to retrieve and display the values of both variables from each KV 'screen' because they belong to the same root screen-Manager class. But I haven't been able to figure out how to grab and manipulate the same variables in a popup window, since that isn't under the screen-Managers jurisdiction. (Somewhere in some tutorial, I learned to create a popoup in KVlang using the Factory import.) But if I want to set "A" = 0 in a popup, I am stumped. Should I use __init__, global variables, app, App.get_screen, parent/child assert, id,kv properties, bind.

Is resetting "A" & "B" to zero from the popup on either screen something easily accomplished? Am I far off base? How about changing the "B" value from a button on page one, or the "A" value from a button on page two?

I use ggeffects::ggemmeans() to get predictions from models, and I don't know whether I found a bug or otherwise doing things wrong. When using a factor variable as a predictor in the model, the output of ggemmeans() gets messed up when releveling the factor.

Below there are two scenarios, a and b, in which I convert a data column to a factor, then fit a model with lm() and finally calculate predictions with ggemmeans().

I have 2 dropdowns with car manufacturer and models!

I am trying to fill the first dropdown with the manufacturers that are in Json in the content "makes:[]" when selecting manufacturer I wanted to load the second dropdown with the models of that json "models:[]"

An example I want to do is the same as this site: SITE

I have a table named 'home' that is storing Arsenal football club's performance in the league at home in 2003-04 season, while the table 'away' stores Arsenal's performance away in the same season.

I want to create a new column which categorizes the values in the manufacturer column to their contintent of origen e.g. Europe for Volkswagen. The values in the manufacturer columns are objects.

Im trying to use the following function:
