| How do I break the while statement?(java) Posted: 16 Jul 2021 08:41 AM PDT So this program asks for different areas of shapes, and it was requested that the user be able to control whether they want the program to continue or stop. I created an if statement, within the while loop that if the user entered "stop" the program would break. However, after testing the program is continuing to run. How do I break the while loop? import java.util.Scanner; public class assignmentu3b { static int area; static String stop; public static void main(String[]args) { Scanner sc=new Scanner(System.in); System.out.println("Would you like to find the area of a rectangle,circle or triangle"); String inp=sc.next(); inp.toLowerCase(); while(true) { System.out.println("Enter stop, to leave the program, or anythinng else to continue, the program will run once."); stop=sc.next(); stop.toLowerCase(); if(stop=="stop") { break; } switch(inp) { case "circle": area=circle(area); System.out.println("The area of the circle is "+area); break; case "rectangle": area=rectangle(area, area); System.out.println("The area of the rectangle is "+area); break; case "triangle": area=triangle(area, area); System.out.println("The area of the triangle is "+area); break; default: System.out.println("You didn't enter a shape"); } } } public static int circle(int radius) { Scanner sc= new Scanner(System.in); System.out.println("Enter a radius:"); radius=sc.nextInt(); return (int) (Math.PI*Math.pow(radius,2)); } public static int rectangle(int lenght,int width) { Scanner sc= new Scanner(System.in); System.out.println("Enter a lenght and width"); lenght=sc.nextInt(); width=sc.nextInt(); return lenght*width; } public static int triangle(int base,int height) { Scanner sc= new Scanner(System.in); System.out.println("Enter a base and height"); base=sc.nextInt(); height=sc.nextInt(); return (base*height)/2; }

| Is there a way to calculate incremental area under the curve for each id subject? Posted: 16 Jul 2021 08:41 AM PDT I'm working in R and i'm trying to generate a data.frame with the incremental area under the curve of glucose values above baseline for each subject id (ID). In particular my dataset is like that: ID glucose Time 101 100 0 102 70 0 103 60 0 101 50 0.5 102 85 0.5 103 70 0.5 101 55 1 102 69 1 103 96 1
I'm using the function by Brouns et al (2005): auc.fn <- function(x,y) { auc <- ifelse(y[2] > y[1], (y[2]-y[1])*(x[2]-x[1])/2, 0) seg.type <- 0 for (i in 3:length(x)) { if (y[i] >= y[1] & y[i-1] >= y[1]) { auc[i-1] <- (((y[i]-y[1])/2) + (y[i-1]-y[1])/2) * (x[i]-x[i-1])/2 seg.type[i-1] <- 1 } else if (y[i] >= y[1] & y[i-1] < y[1]) { auc[i-1] <- ((y[i]-y[1])^2/(y[i]-y[i-1])) * (x[i]-x[i-1])/2 seg.type[i-1] <- 2 } else if (y[i] < y[1] & y[i-1] >= y[1]) { auc[i-1] <- ((y[i-1]-y[1])^2/(y[i-1]-y[i])) * (x[i]-x[i-1])/2 seg.type[i-1] <- 3 } else if (y[i] < y[1] & y[i-1] < y[1]) { auc[i-1] <- 0 seg.type[i-1] <- 4 } else { # The above cases are exhaustive, so this should never happpen return(cat("i:", i, "Error: No condition met\n")) } } return(list(auc=sum(auc), segments=auc, seg.type=seg.type)) }
However, this function returns only the whole AUC value. How can i change the function in order to have for each id subject an AUC value? Many thanks  |

| How return "true" or "false" after checking if an element exists in a JSON file? Posted: 16 Jul 2021 08:41 AM PDT I have this function in my JavaScript file function checkFrom(rootItems){ fetch("./../../../data_dragon/11.10.1/data/en_US/item.json") .then(response => response.json()) .then(function(data){ const itemlist=data.data console.log(itemlist[rootItems[0]]) for(const Item in rootItems){ if(typeof itemlist[Item].from != undefined){ return true } } return false }) }
The problem is that the two statements where I return "true" or "false" returns it for the function used to interact with the JSON file I use and not for the "checkFrom" function. So my question is how can I make it return the Boolean for this "checkFrom" function ? I tried to set the data of the JSON as a global variable (as var, const or let) but when I try to use this variable it's undefined.  |
| Checking if all non-NA elements between two or more columns or vectors are identical Posted: 16 Jul 2021 08:40 AM PDT I have two columns in a dataframe that contain date information after a left outer join. Because of the style of join, one of the date columns now contains NAs. I want to check if all non-NA values are identical between these columns. An example is below: date 1 date 2 1/1/21 NA 1/2/21 1/2/21 1/3/21 NA 1/4/21 1/4/21
I don't need the second column if all non-NA values match Before I did the left outer join, I did a outer join and this statement: identical(df[['date 1']], df[['date 2']])
returned a true Is there a way to use this or a similar statement with just ignoring all rows that contain an "NA" in "date 2"?  |

| ScrollTo on click not scrolling to the correct list item Posted: 16 Jul 2021 08:41 AM PDT I have an SVG map and a list where if you click on a plot number on the map it highlights on the list. As there are quite a few items, when you click on a plot number on the map its supposed to scroll the list on the right to the correct item. However as you start clicking around on all different numbers you can see the scroll breaks and it no longer scrolls to the correct number. Codepen here.

| User created instance Posted: 16 Jul 2021 08:41 AM PDT I am trying to complete a homework assignment about python classes that has a few requirements: Your program will prompt the user to create at least one object of each type (Car and Pickup). Using a menu system and capturing user input your program will allow the user the choice of adding a car or pickup truck and define the vehicle's attributes. The program will use user input to define the vehicle's attributes. The options attribute in the parent class must be a python list containing a minimum of eight (8) options common to all vehicles. The user will choose from a list of options to add to the vehicle's options list and must choose a minimum of one vehicle option per vehicle. When the user is finished adding vehicles to their virtual garage the program will output the vehicles in their garage and their attributes. I haven't started on the child classes yet because I want to make sure the parent class works as needed before adding more. My program kind of works but I have to create the instance manually. My question is, how do I make a user-inputted instance so that I can make repeat entries? class Vehicle: def __init__(self, make, model, color, fuelType,options): self.make = make self.model = model self.color = color self.fuelType = fuelType self.options = options def getMake(self): self.make = input('Please enter the vehicle make: ') def getModel(self): self.model = input('Please enter the vehicle model: ') def getColor(self): self.color = input('Please enter the vehicle color: ') def getFuelType(self): self.fuelType = input('Please enter the vehicle fuel type: ') def getOptions(self): optionslist = [] print('\nEnter Y or N for the following options') radio = input('Does your vehicle have a radio: ').lower() bluetooth = input('Does your vehicle have bluetooth: ').lower() cruise = input('Does your vehicle have cruise control: ').lower() window = input('Does your vehicle have power windows: ').lower() lock = input('Does your vehicle have power locks: ').lower() mirror = input('Does your vehicle have power mirrors: ').lower() rstart = input('Does your vehicle have remote start: ').lower() bcamera = input('Does your vehicle have a back up camera: ').lower() if radio == 'y': optionslist.append('Radio') if bluetooth == 'y': optionslist.append('Bluetooth') if cruise == 'y': optionslist.append('Cruise Control') if window == 'y': optionslist.append('Power Windows') if lock == 'y': optionslist.append('Power Locks') if mirror == 'y': optionslist.append('Power Mirrors') if rstart == 'y': optionslist.append('Remote Start') if bcamera == 'y': optionslist.append('Backup Camera') self.options = optionslist #creates instance selection1 = Vehicle('n','n','n','n','n') Vehicle.getMake(selection1) Vehicle.getModel(selection1) Vehicle.getColor(selection1) Vehicle.getFuelType(selection1) Vehicle.getOptions(selection1) #makes sure options list has at least one option if not selection1.options: print('\nYou need to select at least one option.')

| SQL window function and running total Posted: 16 Jul 2021 08:40 AM PDT I'm learning SQL and want to understand the window function better. Let's say I have a set of data for a bank account containing: - Latest balance (It only shows the latest balance and not historical ones)
- Transaction Date
- Deposit amount
- Withdrawal amount
Out of this data, I want to get a column that shows running total ('balance') at everey transaction as below: <◎What it should look like> | account | latest_balance | date | deposit | withdrawal | balance | | XYZ | 1 000 | 2021-07-16 | 100 | | 1 000 | | XYZ | 1 000 | 2021-07-15 | | 200 | 900 | Because the data does not contain the entire transaction history of this account and the available date is of the latest 1 year, one way to get 'balance' is to make a calculation based on the latest balance. I have tried using the window function for this. However I haven't been able to make it work the way I want to. For example, if I write this part of the select statement like below: SELECT latest_balance - (ISNULL (SUM(deposit) OVER(PARTITION BY account ORDER BY date DESC ROWS UNBOUNDED PRECEDING),0) + ISNULL (SUM(withdrawal)) OVER(PARTITION BY account ORDER BY date DESC ROWS UNBOUNDED PRECEDING),0))
This would return something like below: <✖ How it looks now> | account | latest_balance | date | deposit | withdrawal | balance | | XYZ | 1 000 | 2021-07-16 | 100 | | 900 | | XYZ | 1 000 | 2021-07-15 | | 200 | 700 | This is not what I would like to see as the balance for the first row should say 1 000 instead of 900. I tried different conbinations of ROWS, BETWEEN, UNBOUNDED, PRECEDING and FOLLOWING for this but I still can't figure out how to make it work. Could anyone please share your knowledge and enlighten me? Many thanks! =)  |

Store: import { createStore } from 'redux'; import rootReducer from '../reducer'; export const store = createStore( rootReducer, window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__() ); export default store
My reducer: const initialState = []; const todos = (state = initialState, action) => { switch(action.type) { // Aca va tu codigo; case 'AddTodo': return [...state, action.payload]; case 'RemoveTodo': return state.filter(todo => todo.id !== action.payload) case 'ToInProgress': return state.map((todo) => todo.id === action.payload ? { ...todo, status: "InProgress" } : todo ); case 'ToDone': return state.map((todo) => todo.id === action.payload ? { ...todo, status: "Done" } : todo ); default: return state } } export default todos;

Here's AddTodo: export function AddTodo() { const [state,setState]=React.useState({ title:"", description:"", place:"", date:"", }) function handleChange(e){ const value=e.target.value; setState({ ...state, [e.target.name]:value }) } function handleSubmit(e){ e.preventDefault(); store.dispatch(addTodo({ place:state.place, title:state.title, date:state.date, description:state.description })) // parameters "id" & "status" loaded in Actions. setState({title:"", description:"", place:"", date:"",}) } return ( <div className="todoContainer"> <form id="formulario"onSubmit={handleSubmit} > <label> Title <input type="text" name="title" value={state.title} onChange={handleChange} /> </label> <label> Description <textarea type="text" name="description" value={state.description} onChange= {handleChange}/> </label> <label> Place <input type="text" name="place" value={state.place} onChange={handleChange}/> </label> <label> Date <input type="text" name="date" value={state.date} onChange={handleChange}/> </label> <button className="boton" type="submit" onClick={addTodo}>Agregar</button> </form> </div> ) }; function mapDispatchToProps(dispatch){ return{ addTodo: todo => dispatch(addTodo(todo)) } } export default connect(mapDispatchToProps)(AddTodo)
Now, i want to show at Todos component, every Todos "title", still didn't know how to perform it: export function Todos(data) { return ( <div className="todoDetail"> <h4>{data.title}</h4> </div> ) }; function mapStateToProps(state) { return { data: state.title, }; } export default connect(mapStateToProps)(Todos)

| Changes in nested ObservedObject do not updated the UI Posted: 16 Jul 2021 08:40 AM PDT When I have a nested ObservedObject, changes in a published property of a nested object do not updated the UI until something happens to the parent object. Is this a feature, a bug (in SwiftUI) or a bug in my code? Here is a simplified example. Clicking the On/Off button for the parent immediately updates the UI, but clicking the On/Off button for the child does not update until the parent is updated. I am running Xcode 12.5.1. import SwiftUI class NestedObject: NSObject, ObservableObject { @Published var flag = false } class StateObject: NSObject, ObservableObject { @Published var flag = false @Published var nestedState = NestedObject() } struct ContentView: View { @ObservedObject var state = StateObject() var body: some View { VStack { HStack { Text("Parent:") Button(action: { state.flag.toggle() }, label: { Text(state.flag ? "On" : "Off") }) } HStack { Text("Child:") Button(action: { state.nestedState.flag.toggle() }, label: { Text(state.nestedState.flag ? "On" : "Off") }) } } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }

| SwiftUI: Display UIMenuController (or equivalent) on tap? Posted: 16 Jul 2021 08:40 AM PDT I have a SwiftUI Text view in my app, and I would like to display a UIMenuController or its SwiftUI equivalent whenever I tap on it. I can capture the tap action successfully by adding an onTapGesture block to my View, but I haven't been able to find any examples showing how to display the menu. Is there a SwiftUI equivalent to UIMenuController? Do I need to create the whole UIViewRepresentable thing for it?  |
| Convert timestamp without timezone into timestamp with timezone Posted: 16 Jul 2021 08:40 AM PDT I have a column that is of type nullable timestamp without time zone. It is stored in my Postgres database in this format: 2021-06-24 11:00:00. And I would like to convert it to a nullable timestamp with time zone type such that it would be displayed as 2021-06-24 11:00:00.000-00. Notice that there is no timezone conversion. The solution should also allow to convert from timestamp with time zone to timestamp without time zone. I did some research and was not able to find anything.  |
| Aerial Attack on Godot Posted: 16 Jul 2021 08:41 AM PDT I'm new to Godot, and I'm making a personal project, a 2D platformer, a clone of Ninja Gaiden (1988), but I'm having trouble getting the aerial attack to work. The Player script is the following: extends KinematicBody2D onready var Animated_player = $AnimatedSprite onready var Sword = $Sword/CollisionShape2D export var Acceleration = 512 export var Max_speed = 64 export var Friction = 0.25 export var Air_resistance = 0.02 export var Gravity = 200 export var Jump_force = 100 var Is_attacking = false var motion = Vector2.ZERO func _physics_process(delta): var x_input = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left") if Input.is_action_just_pressed("Attack"): Animated_player.play("Attack") Sword.disabled = false Is_attacking = true motion.x = 0 if x_input != 0 and Is_attacking == false: Sword.disabled = true Animated_player.play("Walk") motion.x += x_input * Acceleration * delta motion.x = clamp(motion.x, -Max_speed, Max_speed ) Animated_player.flip_h = motion.x < 0 else: if Is_attacking == false: Sword.disabled = true Animated_player.play("Idle") motion.x = lerp(motion.x, 0, Friction * delta) motion.y += Gravity * delta if test_move(transform, Vector2.DOWN): if x_input == 0: motion.x = lerp(motion.x, 0, Friction) if Input.is_action_just_pressed("Jump"): motion.y = -Jump_force else: if Input.is_action_just_pressed("Attack"): Sword.disabled = false motion.x = lerp(motion.x, 0, Air_resistance) Animated_player.play("Jump_Attack") motion.x = lerp(motion.x, 0, Air_resistance) if Is_attacking == false: Sword.disabled = true if motion.y < 0: Animated_player.play("Jump") if motion.y > 0: Animated_player.play("Fall") if Input.is_action_just_released("Jump") and motion.y < -Jump_force/2: motion.y = -Jump_force/2 if x_input == 0: motion.x = lerp(motion.x, 0, Air_resistance) move_and_slide(motion) motion = move_and_slide(motion, Vector2.UP) func _on_AnimatedSprite_animation_finished(): if Animated_player.animation == "Attack" or Animated_player.animation == "Jump_Attack": Is_attacking = false Sword.disabled = true
The Jump_Attack animation plays right, but I want the "Air resistance" to be true while you attack on the air, but if you attack on the ground I want motion.x to be zero. but whenever I make motion.x = 0 inside the if Input.is_action_just_pressed: it stops your movement on the air as well. How can I solve this?  |
| Open Images from Google Drive using Colab Posted: 16 Jul 2021 08:40 AM PDT I am coding a Image Classificator using ResNet18. Train and Test phase work fine. But as a final I want to do a evaluation with 5-10 images. The classificator give out data, target and the images which are classified. Giving out data and target work fine too. But the classificator never shows the classified images to the user. Running on my own GPU I used to use Show.img() . I ve got my data on my Google Drive and mounted the data with from colab.google import drive etc. Which code do I need to implement to show the images to the user. Thanks for your help. PS: I bet I missing a pretty easy answer, but I am running crazy.  |
| Flutter - Prompt for TouchID/FaceID when opening app Posted: 16 Jul 2021 08:40 AM PDT I'm having an issue implementing TouchID/FaceID Authentication in a way where it will automatically prompt the user when they open the app. I am using the local_auth dependency for TouchID/FaceID. In the code below, biometric authentication will pop up when the app resumes, but it is also impossible to dismiss. If you press the home button, it dismisses the TouchID prompt but immediately starts to try again, and causes an endless loop if you keep trying this. It will also randomly prompt twice, so even if you successfully log in with the first TouchID prompt, it will pop up again immediately afterwards. Does anyone know of a way to fix this? I also have a TouchID button on the login page that users can press to manually prompt TouchID, but I'd love to recreate how my banking apps and others work where TouchID prompts when you open the app automatically. void initState() { super.initState(); SystemChannels.lifecycle.setMessageHandler((msg) async { if (msg==AppLifecycleState.resumed.toString()) { // If can pop, app is not at login screen // so don't prompt for authentication if (!Navigator.canPop(context)) { if (_useFingerprint) { SharedPreferences prefs = await SharedPreferences.getInstance(); String password = prefs.getString('password'); biometricAuthentication(_username, password); } } } }); void biometricAuthentication(String user, String pass) async { print("Biometric Authentication Called"); bool didAuthenticate = false; try { didAuthenticate = await localAuth.authenticateWithBiometrics(localizedReason: 'Please authenticate'); } on PlatformException catch (e) { print(e); } if (!mounted) { return; } if (!didAuthenticate) { return; } else { normalLogin(user, pass); } }

| Capture File Properties and Owner Details Posted: 16 Jul 2021 08:41 AM PDT I have two VBA codes. One loops through and prints the file properties, and the other grabs the owner of a file. How do I merge the File Owner VBA code into File Properties to print the file name, modification date and owner onto a sheet? File Properties - VBA Sub MainList() Application.ScreenUpdating = True Set Folder = Application.FileDialog(msoFileDialogFolderPicker) If Folder.Show <> -1 Then Exit Sub xDir = Folder.SelectedItems(1) Call ListFilesInFolder(xDir, True) Application.ScreenUpdating = False End Sub Sub ListFilesInFolder(ByVal xFolderName As String, ByVal xIsSubfolders As Boolean) Application.ScreenUpdating = True Dim xFileSystemObject As Object Dim xFolder As Object Dim xSubFolder As Object Dim xFile As Object Dim rowIndex As Long Set xFileSystemObject = CreateObject("Scripting.FileSystemObject") Set xFolder = xFileSystemObject.GetFolder(xFolderName) rowIndex = Application.ActiveSheet.Range("A65536").End(xlUp).Row + 1 For Each xFile In xFolder.Files Application.ActiveSheet.Cells(rowIndex, 1).Formula = xFile.Path Application.ActiveSheet.Cells(rowIndex, 2).Formula = xFile.Name Application.ActiveSheet.Cells(rowIndex, 3).Formula = xFile.DateLastAccessed Application.ActiveSheet.Cells(rowIndex, 4).Formula = xFile.DateLastModified Application.ActiveSheet.Cells(rowIndex, 5).Formula = xFile.DateCreated Application.ActiveSheet.Cells(rowIndex, 6).Formula = xFile.Type Application.ActiveSheet.Cells(rowIndex, 7).Formula = xFile.Size Application.ActiveSheet.Cells(rowIndex, 8).Formula = xFile.Owner ActiveSheet.Cells(2, 9).FormulaR1C1 = "=COUNTA(C[-7])" rowIndex = rowIndex + 1 Next xFile If xIsSubfolders Then For Each xSubFolder In xFolder.SubFolders ListFilesInFolder xSubFolder.Path, True Next xSubFolder End If Set xFile = Nothing Set xFolder = Nothing Set xFileSystemObject = Nothing Application.ScreenUpdating = False End Sub
File Owner - VBA Sub test() Dim fName As String Dim fDir As String fName = "FileName.JPG" fDir = "C:/FilePath" Range("A1").Value = GetFileOwner(fDir, fName) End Sub Function GetFileOwner(fileDir As String, fileName As String) As String Dim securityUtility As Object Dim securityDescriptor As Object Set securityUtility = CreateObject("ADsSecurityUtility") Set securityDescriptor = securityUtility.GetSecurityDescriptor(fileDir & fileName, 1, 1) GetFileOwner = securityDescriptor.Owner End Function

| Why people don't do WSDL-first? Posted: 16 Jul 2021 08:41 AM PDT I'm currently making a presentation that deals with web services. We created our service using WSDL+XSD-first approach, in which we first created (with the aid of tools) the XSD schema and WSDL and then compiled both to .NET and Java classes for interoperation. I want to justify why we used this approach. I mentioned that it's more OOP-compliant (first define interface, then implementation, not vice versa) and that you have more control over interoperability constraints. Also, you can define namespaces explicitly and help reuse XSDs across applications On the contrary, today, still many people prefer implementing the code in their IDE and generate WSDL from there. The question is, why?  |
| How do I rename files using R? Posted: 16 Jul 2021 08:40 AM PDT I have over 700 files in one folder named as: files from number 1 to number9 are named for the first month: water_200101_01.img water_200101_09.img
files from number 10 to number30 are named: water_200101_10.img water_200101_30.img
And so on for the second month: files from number 1 to number9 are named: water_200102_01.img water_200102_09.img
files from number 10 to number30 are named: water_200102_10.img water_200102_30.img
How can I rename them without making any changes to the files. just change the nams, for example water_1 water_2 ...till... water_700

| Using accelerometer, gyroscope and compass to calculate device's movement in 3D world Posted: 16 Jul 2021 08:40 AM PDT I'm working on an android application which can calculate device's movement in 6 direction. I think I can use acceleration as; "x=a.t^2" but a is not a constant. And this is the problem. How can I calculate the total movement??  |
