| How do I make SwiftUI show entire vertical content on iPad? Posted: 24 Jun 2021 08:12 AM PDT I have a SwiftUI application that was laid out using an iPhone. Now when I run it on an iPad, it appears to fill the entire width of the screen, but much of the view content is cutoff on the top and bottom. The top level view contains a container (which can hold any number of different views, based on navigation) and a splash view, which times out after the animation. Is there a way to tell it to honor the size required to fit all of the vertical views, and auto-size the width? This is the top level view. I can post more, but that is a lot of code. import SwiftUI struct ContentView: View { @State var showSplash = true var body: some View { ZStack() { ContainerView() SplashView() .opacity(showSplash ? 1 : 0) .onAppear { DispatchQueue.main.asyncAfter(deadline: .now() + 3.5) { withAnimation() { self.showSplash = false splashDidFinish() } } } }.onAppear { NSLog(".onAppear()") } } func splashDidFinish() { NotificationCenter.default.post(name: NSNotification.Name(rawValue: "checkApplicationReady"), object: nil) } }

| FFMPEG Recording Audio from Adafruit I2S MEMS Microphone Having Issues Posted: 24 Jun 2021 08:12 AM PDT I am attempting to use FFMPEG to record and stream video off a Raspberry Pi Zero using the pi camera and the Adafruit I2S MEMS Microphone. I have successfully gotten video recording, but I am having trouble getting the audio correctly added on. I followed the directions at https://learn.adafruit.com/adafruit-i2s-mems-microphone-breakout/raspberry-pi-wiring-test and using their command of arecord -D dmic_sv -c2 -r 44100 -f S32_LE -t wav -V mono -v file.wav I do get a correct audio recording with no issues. However with my FFMPEG command of ffmpeg -f alsa -ar 44100 -ac 2 -c:a pcm_s32le -i default:CARD=sndrpii2scard -vcodec h264 -framerate 30 -i - -pix_fmt yuv420p -preset ultrafast -crf 0 -vcodec copy -codec:a aac -f segment -segment_time 1800 -segment_start_number 1 /RPICRecord%04d.mkv (The last bit starting at -f segment varies depending on recording vs streaming) I get audio that sorta just has a blip and then sounds like it's resetting. The actual recorded video also seems to not play correctly locally, however it does on YouTube. Testing with streaming the video and audio does the same, but it produces a consistent pattern on the audio blips. In the stream video I also finger snap 5 or so times, but you only ever hear 2, so it's for sure not recoding everything. My limited knowledge of FFMPEG has failed me here to understand why this happens or how to debug this further to work towards a fix. Let me know if there is any additional info or logs that would be beneficial.  |

| Malvika is peculiar about color of balloons Posted: 24 Jun 2021 08:12 AM PDT This is a problem of codechef
Little Malvika is very peculiar about colors. On her birthday, her mom wanted to buy balloons for decorating the house. So she asked her about her color preferences. The sophisticated little person that Malvika is, she likes only two colors — amber and brass. Her mom bought n balloons, each of which was either amber or brass in color. You are provided this information in a string s consisting of characters 'a' and 'b' only, where 'a' denotes that the balloon is amber, where 'b' denotes it being brass colored. When Malvika saw the balloons, she was furious with anger as she wanted all the balloons of the same color. In her anger, she painted some of the balloons with the opposite color (i.e., she painted some amber ones brass and vice versa) to make all balloons appear to be the same color. As she was very angry, it took her a lot of time to do this, but you can probably show her the right way of doing so, thereby teaching her a lesson to remain calm in difficult situations, by finding out the minimum number of balloons needed to be painted in order to make all of them the same color. #include <iostream> using namespace std; int main() { string s; int n; cin >> n; while (n--) { cin >> s; int count = 0; int c = 0; for(int i = 0; s[i] != '\0'; i++) { if(s[i] == 'a'){ count++; } else if (s[i] == 'b') { c++; } } if (c == count) { cout << "1" <<endl; }else if (c > count ) { cout << count << endl; }else if (c < count) { cout << c << endl; }else if (c == 0 ) { cout << count << endl; } else if (count == 0) { cout << c << endl; } } return 0; } My sample output is correct but the code is failing while submission.

| The incrementing here continues to return a 0 value Posted: 24 Jun 2021 08:11 AM PDT I was writing the solution to this codewars problem however I've ran into a bit of an issue. Problem statement: Write a function, persistence, that takes in a positive parameter num and returns its multiplicative persistence, which is the number of times you must multiply the digits in num until you reach a single digit, e.g.: persistence(39) # returns 3, because 39=27, 27=14, 1*4=4 and 4 has only one digit
def persistence(n, t=1, x=0): if len(str(n)) > 1: number = [int(i) for i in str(n)] for i in number: t = t * i if len(str(t)) > 1: x += 1 return(persistence(t,x)) else: return(x) else: return 0
I can't quite figure out what the error is in this code. My hunch is that it's either a parameter error or the way the return() value is placed. In essence, the code for distilling an integer to it's multiples is correct, so I just added an extra parameter to persistence; setting x = 0 and making it so that each time the if condition was fulfilled it would increment that exact x value. Once the number was distilled, simply output x. Yet it continues to simply output 0 as the final answer. What's the problem here?  |
| RuntimeError: Working outside of request context Flask Posted: 24 Jun 2021 08:12 AM PDT I am trying out a web application that captures video from the client, processes it at the server-side and prints appropriate message. I was able to capture the video in frames and process every frame. For displaying the frames back to the client, I used a code from the internet that yields the frame and renders it. However, there needs to be an if condition before yielding the frame. def gen(camera): while True: frame, persons = camera.get_frame() if persons == 2: flash('2 people detected.') yield(b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n') @app.route('/video_feed') def video_feed(): return Response(gen(VideoCamera()), mimetype='multipart/x-mixed-replace; boundary=frame')
The if-condition needs to be evaluated and display a flash message. But, whenever there are 2 persons in the frame, the server crashes with the error: Debugging middleware caught exception in streamed response at a point where response headers were already sent.

| Export PDF file from Excel template with Qt and QAxObject Posted: 24 Jun 2021 08:12 AM PDT The project I am currently working on is to export an Excel file to PDF. The Excel file is a "Template" that allows the generation of graphs. The goal is to fill some cells of the Excel file so that the graphs are generated and then to export the file in PDF. I use Qt in C++ with the QAxObject class and all the data writing process works well but it's the PDF export part that doesn't. The problem is that the generated PDF file also contains the data of the graphs while these data are not included in the print area of the Excel template. The PDF export is done with the "ExportAsFixedFormat" function which has as a parameter the possibility to ignore the print area that is "IgnorePrintAreas" at position 5. Even if I decide to set this parameter to "false", so not to ignore the print area and therefore to take into account the print area, this does not solve the problem and it produces the same result as if this parameter was set to "true". I tried to vary the other parameters, to change the type of data passed in parameter or not to use any parameter but it does not change anything to the obtained result which is always the same. Here is the link to the "documentation" of the export command "ExportAsFixedFormat": https://docs.microsoft.com/en-us/office/vba/api/excel.workbook.exportasfixedformat I give you a simplified version of the command suite that is executed in the code: Rapport::Rapport(QObject *parent) : QObject(parent) { //Create the template from excel file QString pathTemplate = "/ReportTemplate_FR.xlsx" QString pathReporter = "/Report" this->path = QDir(QDir::currentPath() + pathReporter + pathTemplate); QString pathAbsolute(this->path.absolutePath().replace("/", "\\\\")); //Create the output pdf file path fileName = QString("_" + QDateTime::currentDateTime().toString("yyyyMMdd-HHmmssff") + "_Report"); QString pathDocument = QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation).append("/").replace("/", "\\\\"); QString exportName(pathDocument + fileName + ".pdf"); //Create the QAxObjet that is linked to the excel template this->excel = new QAxObject("Excel.Application"); //Create the QAxObject « sheet » who can accepte measure data QAxObject* workbooks = this->excel->querySubObject("Workbooks"); QAxObject* workbook = workbooks->querySubObject("Add(const QString&)", pathAbsolute); QAxObject* sheets = workbook->querySubObject("Worksheets"); QAxObject* sheet = sheets->querySubObject("Item(int)", 3); //Get some data measure to a list of Inner class Measurement QList<Measurement*> actuMeasure = this->getSomeMeasure() ; //no need to know how it's work… //Create a 2 dimentional QVector to be able to place data on the table where we want (specific index) QVector<QVector<QVariant>> vCells(actuMeasure.size()); for(int i = 0; i < vCells.size(); i++) vCells[i].resize(6); //Fill the 2 dimentional QVector with data measure int row = 0; foreach(Measurement* m, actuMeasure) { vCells[row][0] = QVariant(m->x); vCells[row][1] = QVariant(m->y1); vCells[row][2] = QVariant(m->y2); vCells[row][3] = QVariant(m->y3); vCells[row][4] = QVariant(m->y4); vCells[row][5] = QVariant(m->y5); row++; } //Transform the 2 dimentional QVector on a QVariant object QVector<QVariant> vvars; QVariant var; for(int i = 0; i < actuMeasure.size(); i++) vvars.append(QVariant(vCells[i].toList())); var = QVariant(vvars.toList()); //Set the QVariant object that is the data measure on the excel file sheet->querySubObject("Range(QString)", "M2:AB501")->setProperty("Value", var); //Set the fileName on the page setup (not relevant for this example) sheet->querySubObject("PageSetup")->setProperty("LeftFooter", QVariant(fileName)); //Export to PDF file with options – NOT WORKING !!! workbook->dynamicCall("ExportAsFixedFormat(const QVariant&, const QVariant&, const QVariant&, const QVariant&, const QVariant&)", QVariant(0), QVariant(exportName), QVariant(0), QVariant(false), QVariant(false)); //Close workbooks->dynamicCall("Close()"); this->excel->dynamicCall("Quit()"); }
A this point I really need help to find a way to solve this problem. I also wonder if this is not a bug of the QAxObject class.  |

For that I will need to send a mail to user and verify maybe by asking to click in the link or sending an OTP but idk how to do that this is my code public class SignUp extends AppCompatActivity implements AdapterView.OnItemSelectedListener { ActivitySignUpBinding binding; private FirebaseAuth mAuth; FirebaseDatabase database; ProgressDialog progressdialog; private Spinner spinner; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); binding=ActivitySignUpBinding.inflate(getLayoutInflater()); setContentView(binding.getRoot()); spinner=findViewById(R.id.spinner3); ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this,R.array.Options, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); spinner.setOnItemSelectedListener(this); mAuth = FirebaseAuth.getInstance(); database=FirebaseDatabase.getInstance(); progressdialog=new ProgressDialog(SignUp.this); progressdialog.setTitle("Creating Account"); progressdialog.setMessage("please wait while we create your account"); binding.SignUp.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { progressdialog.show(); mAuth.createUserWithEmailAndPassword(binding.Email.getText().toString() ,binding.Password.getText().toString()).addOnCompleteListener(new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { progressdialog.dismiss(); if (task.isSuccessful() && !binding.Username.getText().toString().equals("") && !binding.Username.getText().toString().contains("")) { Users user=new Users(binding.Username.getText().toString(),binding.Email.getText().toString(),binding.Password.getText().toString()); String id=task.getResult().getUser().getUid(); String selectedOption = spinner.getSelectedItem().toString(); database.getReference().child("Users").child(selectedOption).child(id).setValue(user); Intent intent; if(selectedOption.contains("Driver")){ intent = new Intent(SignUp.this, HomePage.class); } else{ intent = new Intent(SignUp.this, Custhomepage.class); } startActivity(intent); } else { Toast.makeText(SignUp.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show(); } } });//to check if value match } }); } @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { String text=parent.getItemAtPosition(position).toString(); } @Override public void onNothingSelected(AdapterView<?> parent) { } }

| How to secure NIFI site-to-site with basic auth Posted: 24 Jun 2021 08:12 AM PDT My purpose is to collect some changed data of remote database to a nifi instance via site-to-site and internet. How could I protect the input port on the internet via user/password ? I'm not meaning ssl connection but prevent unauthorized invokation. Is site-to-site suitable for this situation ? or use http processors instead of s2s ?  |
| Float graphic figure and caption around text in rmarkdown for hmtl output Posted: 24 Jun 2021 08:12 AM PDT I am trying to build an html report using knitr where there is text description with some figures mixed in. If possible, I would like to be able to float a figure to the side and have text in the unused space. I am part of the way there, but my problem is that the figure caption is now dissociated from the figure itself. See image below for example. Here is reproducible code: --- title: "caption_testing" author: "Me" date: "6/23/2021" output: html_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ``` Est pellentesque elit ullamcorper dignissim cras. Turpis egestas maecenas pharetra convallis posuere. Iaculis urna id volutpat lacus laoreet. Id volutpat lacus laoreet non. Vulputate dignissim suspendisse in est ante in. Elit eget gravida cum sociis natoque penatibus. Bibendum at varius vel pharetra vel turpis ### An uninteresting heading that spans the width of the page. ```{r echo=FALSE, fig.cap="**Figure 1**. This figure caption to ideally be placed underneath the figure where it will have many words and explain great things. As a bonus, the caption margins will match up with that of the figure.", out.width='60%', out.extra='style="float:right; padding:10px"', fig.align='right'} knitr::include_graphics('darwinBubble.png') ``` Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Vel eros donec ac odio tempor orci dapibus ultrices in. Auctor augue mauris augue neque. Ornare arcu odio ut sem nulla pharetra diam. Enim blandit volutpat maecenas volutpat. Nisi quis eleifend quam adipiscing vitae proin sagittis nisl. Mi ipsum faucibus vitae aliquet nec ullamcorper. Cursus euismod quis viverra nibh cras pulvinar. Eget nunc scelerisque viverra mauris. Pharetra convallis posuere morbi leo. Elit scelerisque mauris pellentesque pulvinar pellentesque. Semper risus in hendrerit gravida rutrum quisque non tellus. Massa vitae tortor condimentum lacinia quis vel eros donec. Ultrices gravida dictum fusce ut placerat orci nulla pellentesque dignissim. Nec ultrices dui sapien eget mi proin sed libero. Ac tortor vitae purus faucibus ornare suspendisse sed nisi lacus. Ultrices mi tempus imperdiet nulla. Magna ac placerat vestibulum lectus mauris ultrices. Amet dictum sit amet justo donec enim diam. Neque viverra justo nec ultrices dui sapien. Enim nulla aliquet porttitor lacus luctus accumsan tortor. Etiam non quam lacus suspendisse faucibus interdum posuere lorem. Id velit ut tortor pretium viverra suspendisse potenti nullam ac.
Here is that same r chunk, but with only the essentials. I don't believe fig.align is doing any or much of the work here, but I got the idea to use out.extra from another SO post that I cannot find right now. {r echo=FALSE, fig.cap="caption", out.width='60%', out.extra='style="float:right; padding:10px"', fig.align='right'} knitr::include_graphics('darwinBubble.png')
And here is what this produces for me. 
Thanks in advance, any help appreciated!  |
| Why does this SwiftUI code show "Empty" in the destination screen? Posted: 24 Jun 2021 08:12 AM PDT struct ContentView: View { @State var showModal = false @State var text = "Empty" var body: some View { Button("show text") { text = "Filled" showModal = true } .sheet(isPresented: $showModal) { VStack { Text(text) Button("print text") { print(text) } } } } }
I thought that when the "show text" button was tapped, the value of text would be set to "Filled" and showModal would be set to true, so that the screen specified in sheet would be displayed and the word "Filled" would be shown on that screen. I thought it would show "Filled", but it actually showed "Empty". Furthermore, when I printed the text using the print text button, the console displayed "Filled". Why does it work like this? What am I missing to display the value I set when I tap the button on the destination screen? using Xcode12.4, Xcode12.5
Add the code for the new pattern. struct ContentView: View { @State var number = 0 @State var showModal = false var body: some View { VStack { Button("set number 1") { number = 1 showModal = true print("set number = \(number)") } Button("set number 2") { number = 2 showModal = true print("set number = \(number)") } Button("add number") { number += 1 showModal = true print("add number = \(number)") } } .sheet(isPresented: $showModal) { VStack { let _ = print("number = \(number)") Text("\(number)") } } } }
In the above code, when I first tap "set number 1" or "set number 2", the destination screen shows "0". No matter how many times you tap the same button, "0" will be displayed. However, if you tap "set number 2" after tapping "set number 1", it will work correctly and display "2". If you continue to tap "set number 1", "1" will be displayed and the app will work correctly. When you tap "add number" for the first time after the app is launched, "0" will still be displayed, but if you tap "add number" again, "2" will be displayed and the app will count up correctly. This shows that the rendering of the destination screen can be started even when the @State variable is updated, but only when the @State variable is referenced first in the destination screen, it does not seem to be referenced properly. Can anyone explain why it behaves this way? Or does this look like a bug in SwiftUI?  |
| SQL / Postgresql count multiple columns with conditions Posted: 24 Jun 2021 08:12 AM PDT I have a simple table of the form: | id | gender | a_feature (bool) | b_feature (bool) | ... | xyz_feature (bool) | and I want to sum over all feature columns dependent on gender. | metric | male | female | | a_feature | 345 | 3423 | | b_feature | 65 | 143 | | ... | ... | ... | | xyz_feature | 133 | 5536 | Is there a simple way to do this, e.g. using the information_schema. I found only the solution below, but this is very ugly: select 'a_feature' as feature_name, count(case a_feature and gender = 'male') as male, count(case a_feature and gender = 'female') as female from table union select b_feature as feature_name, count(case b_feature and gender = 'male') as male, count(case b_feature and gender = 'female') as female from table . . . select xyz_feature as feature_name, count(case xyz_feature and gender = 'male') as male, count(case xyz_feature and gender = 'female') as female from table

| Change rectangular Qt button to round Posted: 24 Jun 2021 08:12 AM PDT I'm trying to create a round button in Qt. A simple form with a single button QPushButton was created in designer. I'm attempting to turn this into a round button using setMask(). As soon as setMask() is applied the button disappeares. Does a custom widget need to be created to make a round button? #include "mainwindow.h" #include "ui_mainwindow.h" #include <QMessageBox> #include <QtGui/QPushButton> MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); ui->pushButton->setText("Test Text"); ui->pushButton->setFixedHeight(200); ui->pushButton->setFixedWidth(200); //Set Starting point of region 5 pixels inside , make region width & height //values same and less than button size so that we obtain a pure-round shape QRegion* region = new QRegion(*(new QRect(ui->pushButton->x()+5,ui->pushButton->y()+5,190,190)),QRegion::Ellipse); ui->pushButton->setMask(*region); ui->pushButton->show(); } MainWindow::~MainWindow() { delete ui; } void MainWindow::on_pushButton_clicked() { QMessageBox msgbox; msgbox.setText("Text was set"); msgbox.show(); }
Note: If the button is created in code and applied to a window before the window is displayed, the button is displayed. I would like to use the WYSIWIG capabilities of the Qt Designer rather than creating the entire form in code.  |
| Truncate number to two decimal places without rounding Posted: 24 Jun 2021 08:12 AM PDT Suppose I have a value of 15.7784514, I want to display it 15.77 with no rounding. var num = parseFloat(15.7784514); document.write(num.toFixed(1)+"<br />"); document.write(num.toFixed(2)+"<br />"); document.write(num.toFixed(3)+"<br />"); document.write(num.toFixed(10));
Results in - 15.8 15.78 15.778 15.7784514000
How do I display 15.77?  |
