Array related question, cant find the pattern |

So first of all what we're talking about here is not strictly the CQRS pattern, but designing of the domains. Where does the "user" end, and where does the "student" (who's also a "user") start. Encapsulation of logic, stuff like that. Domain-driven development says "hello" :)
First things first.
> Right now what I am doing is, in createStudent handler, I have injected repositories for user, userAddresses and userContacts and using them in the handler to get/create/update records related to user, address or contacts.
I'm pretty sure this can be handled with one repository only. If you define relations for user (1:M addresses), any mutation of the data layer can be done with cascade updates:
```typescript
let user = await this.userRepo.getOne(userId);
const newAddress = new Address({...});
user.addresses.push(newAddress);
await this.userRepo.save(user);
```
(of course, that's in pseudocode).
I'd think of a general rule to keep one repository, always, per CQRS handler. If something cannot be done with one repository, then it means the scope of that handler is too vast (leaking boundaries, something that's of user's shouldn't be doing direct mutations on address, which is a separate domain).
---
> If I switch to a microservices approach where the user and student will be different microservices with different databases, I will not be able to inject the repository
Why different _databases_, by default? You can have your microservices interacting with your one and only data layer, and that's still valid, unless there are certain reasons for separating databases. You can have your microservices doing their stuff and not interacting with data layer at all, but receiving everything over messaging bus, and over messaging bus responding to the main app that's responsible for data handling. But still, if you inject repository for _one_ entity or schema (if you're using eg. `mongoose`), and define your relations well, you can still inject a single repository (recommended, definitely) to a microservice, and cascading will work.
But if you will say sth like "but I need to have more than one repository", then it means that domain boundaries should be most likely reconsidered :) |

You could try this approach using a helper `struct FontModel` to
hold the font results and make it easier to use in the `ForEach` loop.
struct ContentView: View {
var body: some View {
AddFontStyleItems(DrawModel(curFont: "Helvetica"))
}
}
// for testing
struct DrawModel {
var curFont: String
}
struct FontModel: Identifiable { // <--- here
let id = UUID()
var fontType: String
var fontName: String
var fontWeight: Int
var fontTrait: Int
init(_ arr: [Any]) {
if arr.count < 5 {
self.fontType = arr[0] as? String ?? ""
self.fontName = arr[1] as? String ?? ""
self.fontWeight = arr[2] as? Int ?? 0
self.fontTrait = arr[3] as? Int ?? 0
} else {
self.fontType = ""
self.fontName = ""
self.fontWeight = 0
self.fontTrait = 0
}
}
}
struct AddFontStyleItems: View {
var dm: DrawModel
@State private var fontStyles: [FontModel] = [] // <--- here
init(_ dm: DrawModel) { self.dm = dm }
var body: some View {
ForEach(fontStyles) { curStyle in // <--- here
Button(curStyle.fontName) {
print("---> Style: \(curStyle)")
}
}
.onAppear {
fontStyles = getFontStyles(for: dm.curFont) // <--- here
}
}
func getFontStyles(for fontFamily: String) -> [FontModel] {
var results: [FontModel] = []
if let members = NSFontManager.shared.availableMembers(ofFontFamily: fontFamily) {
for member in members {
results.append(FontModel(member))
}
}
return results
}
}
EDIT-1:
if just want an array of Strings
struct AddFontStyleItems: View {
var dm: DrawModel
@State private var fontStyles: [String] = [] // <--- here
init(_ dm: DrawModel) { self.dm = dm }
var body: some View {
ForEach(fontStyles, id: \.self) { curStyle in // <--- here
Button(curStyle) {
print("---> Style: \(curStyle)")
}
}
.onAppear {
fontStyles = getFontStyles(for: dm.curFont) // <--- here
}
.onChange(of: dm.curFont) { // <--- here
fontStyles = getFontStyles(for: dm.curFont)
}
}
func getFontStyles(for fontFamily: String) -> [String] {
var results: [String] = []
if let members = NSFontManager.shared.availableMembers(ofFontFamily: fontFamily) {
for member in members {
if member.count > 1 {
results.append(member[1] as? String ?? "")
}
}
}
return results
}
}
Or simply:
struct AddFontStyleItems: View {
var dm: DrawModel
var body: some View {
VStack {
ForEach(getFontStyles(for: dm.curFont), id: \.self) { curStyle in
Button(curStyle) {
print("---> dm: \(dm) Style: \(curStyle)")
}
}
}
}
func getFontStyles(for fontFamily: String) -> [String] {
var results: [String] = []
if let members = NSFontManager.shared.availableMembers(ofFontFamily: fontFamily) {
for member in members {
if member.count > 1 {
results.append(member[1] as? String ?? "")
}
}
}
return results
}
}
EDIT-2:
Here is my full test code that shows, changing the `curFont` of the `drawModel` in the parent view,
changes the `AddFontStyleItems` view displaying the Font Styles. Tested on MacOS 14.4.
struct ContentView: View {
@State private var drawModel = DrawModel(curFont: "Helvetica") // <--- here
var body: some View {
VStack {
Button("Change curFont") {
drawModel.curFont = "Times" // <--- here
}.padding(20)
Divider()
Text(drawModel.curFont).foregroundStyle(.red)
Divider()
AddFontStyleItems(dm: drawModel)
Spacer()
}
}
}
struct AddFontStyleItems: View {
var dm: DrawModel
var body: some View {
VStack {
ForEach(getFontStyles(for: dm.curFont), id: \.self) { curStyle in
Button(curStyle) {
print("---> dm: \(dm) Style: \(curStyle)")
}
}
}
}
func getFontStyles(for fontFamily: String) -> [String] {
var results: [String] = []
if let members = NSFontManager.shared.availableMembers(ofFontFamily: fontFamily) {
for member in members {
if member.count > 1 {
results.append(member[1] as? String ?? "")
}
}
}
return results
}
}
struct DrawModel: Identifiable {
let id = UUID()
var curFont: String
}
EDIT-3:
try this approach to `select` the `font` and the `style` for your `DrawModel`.
Example code:
struct ContentView: View {
@State private var drawModel = DrawModel(curFont: "Helvetica") // <--- here
var body: some View {
VStack {
Text(drawModel.curFont).foregroundStyle(.red)
Divider()
AddFontItems(dm: $drawModel) // <--- here $
Spacer()
}
}
}
struct AddFontItems: View {
@Binding var dm: DrawModel // <--- here
var uniqueFontFamilies = NSFontManager.shared.availableFontFamilies //.unique()
var body: some View {
HStack {
ScrollView {
ForEach(uniqueFontFamilies, id: \.self) { curFont in
Button(curFont) {
dm.curFont = curFont
print("---> curFont: \(curFont)")
}
}
}
Spacer()
ScrollView {
ForEach(getFontStyles(for: dm.curFont), id: \.self) { curStyle in
Button(curStyle) {
dm.curFont = dm.curFont + " " + curStyle
print("Set Style:\t \(curStyle)")
}
}
}
}
}
func getFontStyles(for font: String) -> [String] {
var justStyles: [String] = []
if let fontInfo = NSFontManager.shared.availableMembers(ofFontFamily: font ) {
for curFontInfo in fontInfo {
if curFontInfo.count > 1 {
justStyles.append(curFontInfo[1] as? String ?? "")
}
}
}
return justStyles
}
}

while in a specific page i need to know the name of the page, which was set by named routes. i could know with normal 'context', but i couldn't do using global context.
my code:
```
// ModalRoute.of(context)?.settings.name with global context, trying!
import 'package:flutter/material.dart';
void main(){runApp(const MyApp()); }
class MyApp extends StatelessWidget {
const MyApp({super.key});
static GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>(); // <---
@override
Widget build(BuildContext context) {
return MaterialApp(
navigatorKey: MyApp.navigatorKey, // set property // <---
//home: const HomeScreen(),
initialRoute: '/home',
routes: { // ---------------> hash routing
'/home':(context)=> const HomeScreen(),
'/details':(context)=> const DetailsScreen(),
},
);
}
}
class HomeScreen extends StatefulWidget {
const HomeScreen({super.key});
@override
State<HomeScreen> createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
@override
Widget build(BuildContext context) {
//MyApp.navigatorKey.currentState!.context =context,
return Scaffold(
appBar: AppBar(title: const Text('Home Page'),backgroundColor: Colors.blue,),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(
onPressed: (){
print("print context: ${MyApp.navigatorKey.currentContext}"); //print context: Navigator-[LabeledGlobalKey<NavigatorState>#a6af1](dependencies: [HeroControllerScope, UnmanagedRestorationScope], state: NavigatorState#d0a98(tickers: tracking 1 ticker))
},
child: const Text('button 1.1')
),
ElevatedButton(
onPressed: (){
print(ModalRoute.of(MyApp.navigatorKey.currentContext!)?.settings.name ?? "Unknown"); //Unknown //or, MyApp.navigatorKey.currentState!.context
},
child: const Text('button 1.2')
),
ElevatedButton(
onPressed: (){
print("${ModalRoute.of(context)?.settings.name}"); //: /home
},
child: const Text('button 1.3')
),
ElevatedButton(
// onPressed: () {
// Navigator.push(context, MaterialPageRoute(
// settings: const RouteSettings(name: "/detailsScreen"),
// builder: (context)=> const DetailsScreen())
// );
// //Navigator.pushReplacement(context,MaterialPageRoute(builder: (context)=> const DetailsScreen()));
// },
onPressed: (){
Navigator.pushNamed(context, '/details');
},
child: const Text('go to details page'),
),
],
),
),
);
}
@override
void dispose() {
print("Dispose called");
super.dispose();
}
}
class DetailsScreen extends StatefulWidget {
const DetailsScreen({super.key});
@override
State<DetailsScreen> createState() => _DetailsScreenState();
}
class _DetailsScreenState extends State<DetailsScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Details Page'),
backgroundColor: Colors.blue,
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(
onPressed: (){
print("print context: ${MyApp.navigatorKey.currentContext}"); //print context: Navigator-[LabeledGlobalKey<NavigatorState>#ebadf](dependencies: [HeroControllerScope, UnmanagedRestorationScope], state: NavigatorState#5dfff(tickers: tracking 2 tickers))
},
child: const Text('button 2.1')
),
ElevatedButton(
onPressed: (){
print(ModalRoute.of(MyApp.navigatorKey.currentContext!)?.settings.name ?? "Unknown"); //Unknown
},
child: const Text('button 2.2')
),
ElevatedButton(
onPressed: (){
print("${ModalRoute.of(context)?.settings.name}");
},
child: const Text('button 2.3') //: /details
),
],
),
),
);
}
}
```
in above example button 1.2 and 2.2 should print their corresponding page name.
looks like button 1.3 and 2.3 are printing as expected. but
```
ModalRoute.of(MyApp.navigatorKey.currentContext!)?.settings.name
is sending null value.

This is an android project and I need to load a website in a webview.
And one more request here is the website needs to be loaded in a iframe.
This is done by the following step:
1. create a webview
2. I have a sample html file
3. I load my sample html file
4. I call `wewbview.loadHTMLString(sampleHtmlString, "")` to load the site from string;
Sample html:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
</style>
</head>
<body>
<script>
document.addEventListener('touchstart', function(event) {
console.log("document touchstart");
});
</script>
</body>
</html>
```
And webview show all good on device also i can see touch event triggered.
___
Then I will add the iframe part:
1. User input a url to load for example: "https://www.facebook.com"
2. Still I load my sample html file
3. Then I replace the PLACE HOLDER in sample file to the one user input for example: `"https://www.facebook.com"`
4. Then call `wewbview.loadHTMLString(sampleHtmlString, "")`;
Updated sample html:
``` html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.webview-container {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: hidden;
}
iframe {
width: 100%;
height: 100%;
border: none;
}
</style>
</head>
<body>
<div class="webview-container" id="webview-container">
</div>
<script>
function loadWebView(url) {
var iframe = document.createElement('iframe');
iframe.src = url;
document.getElementById('webview-container').innerHTML = '';
document.getElementById('webview-container').appendChild(iframe);
iframe.onload = function() {
console.log("iframe onload");
};
}
document.addEventListener('touchstart', function(event) {
console.log("document touchstart");
});
loadWebView('https://www.example.com');
</script>
</body>
</html>
```
I can see the site loaded in iframe correctly but this time touchstart not trigggered when touched.
I searched few posts then tried:
``` javascript
function loadWebView(url) {
var iframe = document.createElement('iframe');
iframe.src = url;
document.getElementById('webview-container').innerHTML = '';
document.getElementById('webview-container').appendChild(iframe);
iframe.onload = function() {
console.log("iframe onload");
iframe.contentWindow.document.addEventListener('touchstart', function(event) {
console.log("iframe touchstart");
});
};
}
```
But still not working and I am getting the error in console:
```
Uncaught SecurityError: Failed to read a named property 'document' from 'Window':
Blocked a frame with origin "null" from accessing a frame with origin
"https://www.grandbrowser.com".
The frame requesting access has a protocol of "about",
the frame being accessed has a protocol of "https".
Protocols must match.", source: about:blank (41)
```
I also tried to remove the `"https:"` from the url according to this post:
https://stackoverflow.com/questions/21525511/the-frame-requesting-access-has-a-protocol-of-https-the-frame-being-accessed
But then the error in console is gone but the site will not load anymore.
___
Any advice on this issue will be appreciated, thanks in advance.
___
If is ok that if there will issues to use event listener inside a iframe in different domain.
The main feature I want to achieve here is to detect:
To detect touchstart / touchmove / touchend event and then add some css animation above the loaded website in iframe.

I have a left section menu with a list that has pagination implemented. Now I am unsure as to how to handle a situation when the list updates and a new item is added to the top of the current list or multiple new items are added to the top of the list, how do I handle this scenario so that I am still on the selected item before the list was updated?
P.S.- Is it a good idea to recursively search for the order by changing pages when the selected item is not present in the updated list, or is there any better cost effective way to handle this. |

hope you are well. My code is not working properly and I have no idea what is wrong or how to fix it.
I only know that when I add the numbers for a square or rectangle it shows that my shape is a parallelogram.
I have tried my code and the output is showing incorrectly.
I have also looked at you tube videos but nothing is helping me. Please advise as soon as possible.

Hello StackOverflow community,
I'm encountering issues while attempting to generate PDFs using Playwright within a Docker container for my AdonisJS application. Despite successful local development, I faced challenges with Dockerizing the project and encountered issues with TailwindCSS styles not rendering correctly within the container.
Here's a summary of the key points:
- I chose AdonisJS for its MVC architecture and seamless integration of
TailwindCSS and the Edge HTML templating engine.
- While the local setup worked smoothly, Dockerizing the project proved challenging,
with TailwindCSS styles not rendering correctly within the container.
- After extensive troubleshooting, I discovered that the only way to
properly generate PDF styles within the container was to use
TailwindCSS as a CDN in the template header.
- Additionally, the container crashed after the 20th request, with Playwright throwing a "browsertype.launch: timeout 180000ms exceeded" error. This mirrors an issue I previously encountered with Puppeteer and Express on an AWS-hosted server.
I've provided my Dockerfile, which was graciously shared by a community member, for reference:
[Playwright browser launch error in Docker container with AdonisJS project][1]
I'm struggling to understand the inner workings of these PDF libraries and how to optimize them effectively. I've read the documentation and explored possible optimizations, but my limited understanding may be hindering me from fully grasping how they function underneath and how to leverage them to their fullest potential
The error you're seeing, Error during navigation: page.setContent: Timeout 30000ms exceeded, indicates a timeout while setting the content of the page. Upon closer inspection, it seems that the error occurs during my initialization of the browser.
One potential reason for this issue could indeed be related to the contents of the HTML header. Specifically, the inclusion of external resources, such as fonts and stylesheets loaded via CDN, might be contributing to the delay in page rendering.

**Edit Question**
After reading several blogs discussing the issue, I understand that the problem lies in Playwright being unable to open the page within the minimum wait time. In other words, during that time, it couldn't finish loading the HTML resources. Most blogs suggest two solutions: either increasing the default timeout value or deactivating it by setting it to zero. The second option is not highly recommended.
However, I see these solutions applied when making a request to a webpage. In this case, I'm not making a request to any webpage. The resources are supposed to have been previously loaded when Playwright receives the content. It then opens the browser, sets the content of the previously loaded HTML as a string, and draws the PDF. If I understand correctly and this is how it works, then why does it encounter timeout issues when loading the PDF?

If you try to implement a `ListStyle`, you can let Xcode add stubs for protocol conformance. You will then see, that the required functions all start with `_`. This is a clue, that you're not really supposed to be implementing your own `ListStyle`.
However, you might be able to achieve what you're after by creating a wrapper for a `List` that accepts a `ViewBuilder` as parameter. Something like:
```swift
struct CustomList<Content>: View where Content: View {
@ViewBuilder let content: () -> Content
var body: some View {
List {
content()
.foregroundStyle(.pink)
.listRowBackground(
Color.yellow
.clipShape(RoundedRectangle(cornerRadius: 10))
)
}
.listStyle(.plain)
.listRowSpacing(10)
.padding()
.background(.gray)
}
}
struct ContentView: View {
var body: some View {
CustomList {
ForEach(0..<100, id: \.self) { item in
Text("Item \(item)")
}
}
}
}
```
 |
You could try:
lapply(
my_list,
\(x) if ('col3' %in% names(x)) transform(x, col3 = replace(col3, is.na(col3) & tolower(col1) %in% c('v2', 'v3'), 'VAL')) else x
)
Output:
[[1]]
col1 col2 col3 col4
1 v1 wood cup <NA>
2 v2 <NA> VAL pear
3 v3 water fork banana
4 V2 <NA> VAL <NA>
5 V1 water <NA> apple
[[2]]
col1 col2 col4
1 v1 wood <NA>
2 v2 <NA> pear
[[3]]
col1 col3 col4
1 v1 cup <NA>
2 v2 VAL pear
3 v3 VAL banana
4 V3 VAL <NA> |
Alert! I am feeling so embarassed asking such an entry level question here!!!!
Hey guys, I have been working on a project that involves timeseries total electron content data. My goal is to apply statistical analysis and find anomalies in TEC due to earthquake.
I am following [this research paper for sliding IQR method][1]. But for some reason I am not getting results as shown in the paper with the given formulas. So I decided to use the rolling mean + 1.6 STD method.
The problem is when I use ax.fill_between(x1 = index, y1 = ub, y2=lb) method my confidence interval band is being plotted a step further than the data point. Please see the given figure for a better understanding.
Here's what I am currently doing:
```
df = DAEJ.copy()
window = 12
hourly = df.resample(rule="h").median()
hourly["ma"] = hourly["TEC"].rolling(window=window).mean()
hourly["hour"] = hourly.index.hour
hourly["std_err"] = hourly["TEC"].rolling(window=window).std()
hourly["ub"] = hourly["ma"] + (1.67* hourly["std_err"])
hourly["lb"] = hourly["ma"] - (1.67* hourly["std_err"])
hourly["sig2"] = hourly["TEC"].rolling(window=window).var()
hourly["kur"] = hourly["TEC"].rolling(window=window).kurt()
hourly["pctChange"] = hourly.TEC.pct_change(12, fill_method="bfill")
hourly = hourly.dropna()
dTEC = hourly[(hourly["TEC"] > hourly["ub"])]
fig, ax = plt.subplots(figsize=(12,4))
hourly["TEC"].plot(ax=ax, title="TEC Anomaly", label="Station: DAEJ")
ax.fill_between(x=hourly.index, y1=hourly["ub"], y2=hourly["lb"], color="red", label="Conf Interval", alpha=.4)
ax.legend()
```
And here's the result I got!
[TEC Anomaly detection using rolling std method](https://i.stack.imgur.com/cFifC.png)
as seen in the given figure the data and the colored band aren't alinged properly, I know after calculating a rolling mean with a window of 12 hours will result in a 12 hour shifted value but even after dropping the first values I am still not getting an aligned figure.

You can build two masks, one to identify the Role change, and one to identify the difference of index above threshold:
```
m1 = df.Role!= df.Role.shift()
m2 = df['Index'].diff().gt(5)
out = df.groupby((m1|m2).cumsum()).agg(
Role = ('Role', 'first'),
Name = ('Name', ' '.join),
Grade = ('Grade', 'mean')
).reset_index(drop=True)
```
Output:
```
Role Name Grade
0 Provider Alex William Juan 6.666667
1 Provider Pedro 4.500000
2 Client George 8.000000
3 Provider Mark 9.400000
4 Client James 8.100000
5 Transporter Anthony 9.500000
6 Transporter Jason 7.000000

Im developping a web app using reactjs and nextjs. When i run it in dev mode, my ram is used up 100%. Im having a 12gb ram and almost 6gb is used up by node js runtime. My colleague has a 24gb ram and when he run it, node js uses almost 15gb ram. When a modification is done to the code, the node js runtime uses up 100% and everything else crashes.
The versions are as follows (as per package.json);
"next": "^13.2.1",
"react": "^18.2.0"
In the terminal, the below error is displayed.
`<w> [webpack.cache.PackFileCacheStrategy] Caching failed for pack: RangeError: Array buffer allocation failed`
[Terminal log](https://i.stack.imgur.com/bSL96.png)
Ive added the folloing code block to the next.config.js
```
webpack(config, { webpack }) {
config.infrastructureLogging = { debug: /PackFileCache/ }; // Define infrastructureLogging inside the webpack function
return config;
}
```
According to those logs, when the web app starts, it creates a cache file and its size is almost 10gb. Everytime a change is made, the cache file is recreated.

I have been working on a classifier for a few days on Azure Auto ML and when I tried disabling some variables that I do not need, I encountered the below error.
I have never encountered this type of error before. Even after creating a new dataset with just the variables I am interested in, the error persists. I need help to resolve this issue. Thank you

I just swicthed off some of the variables that my model does not need. So I would just create a new version of that data set with less variables that I could use for a new version of the model, which is something I have been constantly doing for the last couple of weeks.
I created a new dataset containing just the variables I need but I get the same error. Now I seem to be getting the same error always, no matter what I do. |
Correcting the Database URL worked for me. |
I want to set axisItems to a PlotItem useing pyqtgraph, I encountered an error while running my code.

plot_item = pg.PlotItem()
plot_item.setAxisItems(axisItems={'bottom':pg.AxisItem('bottom')}) # error occurs here
plot_item.plot(x, y)
plot_item.setTitle("Sine Wave Plot")
plot_item.setLabel("left", "Amplitude", units="V")
plot_item.setLabel("bottom", "Time", units="s")
plot_item.showGrid(True, True)

win.setWindowTitle("PlotItem Example")
win.resize(800, 600)
win.addItem(plot_item)
win.show()
app.exec()
```

This works well, though the blur was a bit abrupt with a larger blur and a 1s Swiper speed. In my case, I also used a transition to match the speed:
.swiper-slide {
filter: blur(40px);
transition: 1s filter linear;
}
.swiper-slide-active {
filter: blur(0);

As you can see, the page is loaded with templates for product categories and a switch for displaying types of products in categories or all products at once.
I need to implement this logic:
When you click on a category element, show products from this category and the “Return to categories” link, while hiding the “Show products by category” switch. When you click on the "Return to Categories" link, everything should return to its original state.
When you click the "Show products in categories" switch, show all products at once, while hiding the product categories template. When you press the switch again, everything should return to its original state.
I'm stuck trying out options for displaying templates, but the logic of their behavior changes every time.
Please explain to me how this logic is implemented, or tell me how to correctly ask in Google. Thank you. |

You could use `labeller` per below to suppress the `layout_order`.
(It is better if you can supply a small amount of sample data with the question.)
``` r
library(tidyverse)
df <- tibble(
Time = 1:8,
nPVI = 21:28,
Group = rep(letters[1:4], 2),
Participant = 1:8,
layout_order = 1:8
)
df$layout_order <- factor(rep(1:ceiling(nrow(df) / 4), each = 4), levels = unique(rep(1:ceiling(nrow(df) / 4), each = 4))[1:nrow(df)])
ggplot(df, aes(x = Time, y = nPVI, group = Time, fill = Group)) +
geom_bar(stat = "identity", position = "dodge", color = "black") +
labs(
title = "nPVI scores by Participant, Time and Group",
x = "Time",
y = "nPVI",
group = "Time"
) +
facet_wrap(~ Participant + layout_order,
scales = "free", ncol = 4,
labeller = labeller(layout_order = \(x) rep("", length(x)))
) +
coord_cartesian(ylim = c(20, 60)) +
scale_fill_manual(values = c("Oral" = "#86CB92", "Prosody" = "#0E7C7B")) +
theme_minimal()

Hey guys, I have been working on a project that involves timeseries total electron content data. My goal is to apply statistical analysis and find anomalies in TEC due to earthquake.
I am following [this research paper for sliding IQR method][1]. But for some reason I am not getting results as shown in the paper with the given formulas. So I decided to use the rolling mean + 1.6 STD method.
The problem is when I use ax.fill_between(x1 = index, y1 = ub, y2=lb) method my confidence interval band is being plotted a step further than the data point. Please see the given figure for a better understanding.
Here's what I am currently doing:
```
df = DAEJ.copy()
window = 12
hourly = df.resample(rule="h").median()
hourly["ma"] = hourly["TEC"].rolling(window=window).mean()
hourly["hour"] = hourly.index.hour
hourly["std_err"] = hourly["TEC"].rolling(window=window).std()
hourly["ub"] = hourly["ma"] + (1.67* hourly["std_err"])
hourly["lb"] = hourly["ma"] - (1.67* hourly["std_err"])
hourly["sig2"] = hourly["TEC"].rolling(window=window).var()
hourly["kur"] = hourly["TEC"].rolling(window=window).kurt()
hourly["pctChange"] = hourly.TEC.pct_change(12, fill_method="bfill")
hourly = hourly.dropna()
dTEC = hourly[(hourly["TEC"] > hourly["ub"])]
fig, ax = plt.subplots(figsize=(12,4))
hourly["TEC"].plot(ax=ax, title="TEC Anomaly", label="Station: DAEJ")
ax.fill_between(x=hourly.index, y1=hourly["ub"], y2=hourly["lb"], color="red", label="Conf Interval", alpha=.4)
ax.legend()
```
And here's the result I got!
as seen in the given figure the data and the colored band aren't alinged properly, I know after calculating a rolling mean with a window of 12 hours will result in a 12 hour shifted value but even after dropping the first values I am still not getting an aligned figure.

I write code for the ESP32 microcontroller.
I set up a class named "dmhWebServer".
This is the call to initiate my classes:
An object of the dmhFS class is created and I give it to the constructor of the dmhWebServer class by reference. For my error see the last code block that I posted. The other code block could explain the way to where the error shows up.
```
#include <dmhFS.h>
#include <dmhNetwork.h>
#include <dmhWebServer.h>
void setup()
{
// initialize filesystems
dmhFS fileSystem = dmhFS(SCK, MISO, MOSI, CS); // compiler is happy I have an object now
// initialize Activate Busy Handshake
dmhActivateBusy activateBusy = dmhActivateBusy();
// initialize webserver
dmhWebServer webServer(fileSystem, activateBusy); // compiler also happy (call by reference)
}
```
The class dmhFS has a custom constructor (header file, all good in here):
```
#include <Arduino.h>
#include <SD.h>
#include <SPI.h>
#include <LittleFS.h>
#include <dmhPinlist.h>
#ifndef DMHFS_H_
#define DMHFS_H_
class dmhFS
{
private:
// serial peripheral interface
SPIClass spi;
String readFile(fs::FS &fs, const char *path);
void writeFile(fs::FS &fs, const char *path, const char *message);
void appendFile(fs::FS &fs, const char *path, const char *message);
void listDir(fs::FS &fs, const char *dirname, uint8_t levels);
public:
dmhFS(uint16_t sck, uint16_t miso, uint16_t mosi, uint16_t ss);
void writeToSDCard();
void saveData(std::string fileName, std::string contents);
String readFileSDCard(std::string fileName);
};
#endif
```
Header file of the dmhWebServer class (not the whole thing):
```
public:
dmhWebServer(dmhFS &fileSystem, dmhActivateBusy &activateBusyHandshake);
};
```
This is the dmhWebServer class:
```
class dmhWebServer
{
private:
// create AsyncWebServer object on port 80
AsyncWebServer server = AsyncWebServer(80);
// server to client communication
AsyncEventSource events = AsyncEventSource("/events");
void setupHandlers();
void setupWebServer();
void serveFiles();
void setupStaticFilesHandlers();
void setupEventHandler();
void setupPostHandler();
void onRequest(AsyncWebServerRequest *request);
// http communication
void sendToClient(const char *content, const char *jsEventName);
void receiveFromClient(std::array<const char *, 2U> par);
// uses SD Card
dmhFS sharedFileSystem;
// uses shared memory for data exchange with a activate busy handshake
dmhActivateBusy abh;
public:
dmhWebServer(dmhFS &fileSystem, dmhActivateBusy &activateBusyHandshake);
};
```
This is the constructor of the dmhWebServer class:
```
#include <dmhWebServer.h>
#include <dmhFS.h>
#include <dmhActivateBusy.h>
// This is the line where the compiler throws an error ,character 85 is ")"
dmhWebServer::dmhWebServer(dmhFS &fileSystem, dmhActivateBusy &activateBusyHandshake)
{
// webserver sites handlers
setupHandlers();
abh = activateBusyHandshake;
sharedFileSystem = fileSystem;
// start web server, object "server" is instantiated as private member in header file
server.begin();
}
```
My compiler says: "src/dmhWebServer.cpp:5:85: error: no matching function for call to 'dmhFS::dmhFS()'"
Line 5:85 is at the end of the constructor function declaration
This is my first question on stackoverflow since only lurking around here :) I try to clarify if something is not alright with the question.
I checked that I do the call by reference in c++ right. I am giving the constructor "dmhWebServer" what he wants. What is the problem here? |
This problem is often called 'assigning agents to tasks'. There are several algorithms that can solve this. I use the Ford-Fulkerson Maximum Flow Algorithm ( theory.stanford.edu/~tim/w16/l/l1.pdf )
The trick is, as always, adapting the algorithm to your particular constraints so that the max flow algorithm operates without violating any of them.
I do not understand some of your constraints ( 'workdays' in particular, see my comments on your question for the clarifications needed ). So I cannot apply all your constraints. But, I thought you might find it useful to see some code ( C++, sorry ) implementing the max flow allocation applied to a simplified version of your problem. This code uses the implementation of Ford-Fulkerson supplied by the PathFinder graph theory library. ( https://github.com/JamesBremner/PathFinder )
```C++
#include <string>
#include <fstream>
#include <sstream>
#include <iostream>
#include <vector>
#include <set>
#include <algorithm>
#include "GraphTheory.h"
class cAgent
{
public:
std::string myID;
std::vector<std::string> myTasks;
bool cando( const std::string& task )
{
return std::find(
myTasks.begin(),myTasks.end(),
task )
!= myTasks.end();
}
};
std::set<std::string> theTasks;
std::vector<cAgent> theAgents;
void readfile()
{
std::ifstream ifs("../dat/data1.txt");
if (!ifs.is_open())
throw std::runtime_error(
"Cannot read input");
std::string line;
while (getline(ifs, line))
{
// std::cout << line << "\n";
if (line.find("id:") != -1)
{
int p = line.find("\"");
int q = line.find("\"", p + 1);
line = line.substr(p + 1, q - p - 1);
if (line[0] == 'T')
{
cAgent A;
A.myID = line;
theAgents.push_back(A);
}
}
else if (line.find("subjects:") != -1)
{
int p = line.find("\"", p + 1);
while (p != -1)
{
int q = line.find("\"", p + 1);
auto task = line.substr(p + 1, q - p - 1);
theTasks.insert(task);
theAgents.back().myTasks.push_back(task);
p = line.find("\"", q + 1);
}
}
else if (line.find("const subjects") != -1)
break;
}
std::cout << "Teachers:\n ";
for (auto &a : theAgents)
{
std::cout << a.myID << " can teach ";
for (auto &t : a.myTasks)
std::cout << t << " ";
std::cout << "\n";
}
}
void allocateMaxFlow()
{
raven::graph::cGraph g;
g.directed();
// loop over the tasks in timeslot
for (auto & task : theTasks)
{
// loop over agents that can do task
for (cAgent &a : theAgents)
{
if( ! a.cando( task ))
continue;
// add link from agent to task agent is able to do
g.add(
a.myID,
task );
}
}
// apply pathfinder maximum flow allocation algorithm
raven::graph::sGraphData gd;
gd.g = g;
auto sg = alloc(gd);
std::cout << "\nAssignments:\n";
for (std::pair<int, int> p : sg.edgeList())
{
std::cout << "teacher " << sg.userName(p.first )
<< " assigned to " << sg.userName (p.second)
<< "\n";
}
}
main()
{
readfile();
allocateMaxFlow();
return 0;
}
```
The output from this is
```

I've got a React component that I have made aware of its own width using ResizeObserver. Inside this component I'm rendering two divs, each one is "flex: 1" so they take equal width. When the component is small enough and certain state conditions are met, I set "display: none" on the first div, allowing the second to take the full width of the flex container.
It is working well to respond to changes in the browser width, but my application also has a side bar that can be opened and closed. When the side bar is closed and enough width is made available by this action, my component recognizes that and adjusts itself to display the "dashboard_monitors" div once again. The problem is, we get one paint where the side bar is closed and the second "dashboard_activity" div is still taking up the full width, and only after this paint does the component update itself and display the "dashboard_monitors" div, which causes a perceivable "jump" as the component positions each div with equal width again.
It seems that I'd need to have the side bar disappear and the component update itself, so they can both paint in the correct state at the same time, but I'm not sure how to accomplish this.
This is the component I'm speaking of:
import './Dashboard.css'
import MonitorComponent from '../../components/Monitor/Monitor';
import DetailComponent from '../../components/Monitor/Detail';
import { Monitor } from '../../monitor'
import { useEffect, useMemo, useState } from 'react';
import { useWidth } from '../../hooks/useWidth';
interface DashboardProps {
monitors: Monitor[]
focused: Monitor | null,
drafting: boolean,
}
export default function Dashboard(props: DashboardProps) {
const {
monitors,
focused,
drafting,
} = props;
const isEditing = useMemo(() => focused || drafting, [focused, drafting]);
const { width: dashboardWidth, ref: dashboardRef } = useWidth<HTMLDivElement>();
const [sorted, setSorted] = useState<Monitor[]>([])
useEffect(() => {
const sorted = monitors.sort((a, b) => {
if (a.strategy.name > b.strategy.name) {
return 1;
} else {
return -1;
}
});
setSorted(sorted);
}, [monitors])
const dashboardClasses = ['dashboard', isEditing && dashboardWidth < 700 ? 'single' : '']
return (
<div className={dashboardClasses.join(' ')} ref={dashboardRef}>
<div className="dashboard_monitors">
{sorted.map((n, i) =>
<MonitorComponent key={i} monitor={n} />)
}
</div>
{isEditing ?
<div className="dashboard_activity">
<DetailComponent monitor={focused} />
</div>
: null}
</div>
)
}
The CSS applied to the component in "Dashboard.css" is here:
.dashboard {
display: flex;
height: 100%;
}
.dashboard.single .dashboard_monitors {
display: none;
}
.dashboard.single .dashboard_activity {
margin-left: 0;
}
.dashboard > * {
flex: 1;
overflow-x: hidden;
overflow-y: auto;
}
.dashboard_activity {
margin-left: var(--padding-2);
}
.dashboard_monitors {
display: grid;
gap: var(--padding-2);
grid-template-columns: repeat(auto-fill, minmax(350px, 1fr));
grid-auto-rows: 200px;
padding-right: var(--padding-0);
padding-bottom: var(--padding-0);
}
The ResizeObserver is in my useWidth hook here:
import { useState, useRef, useEffect } from "react";
export const useWidth = <T extends HTMLElement>() => {
const [width, setWidth] = useState(0);
const ref = useRef<T>(null);
useEffect(() => {
const observer = new ResizeObserver((entries) => {
setWidth(entries[0].contentRect.width);
});
const refElement = ref.current;
if (refElement) {
observer.observe(refElement);
}
return () => {
refElement && observer.unobserve(refElement);
};
}, []);
return { width, ref };
};
If you have any suggestions or questions, thanks for your time. |

The part of the code giving me the error is borrowed from research on how to find a specific value, match it to a value on another worksheet and delete that row of data. The code has multi tasks to complete:
1. Copy the row on sheet22 and paste it to the next empty row on
sheet13
2. Find a match to Sheet22 cell C2 on Sheet 11 column A and
delete the matching row on sheet 11

I think that part of it is I would like to replace the wildcard with a static text string, i.e. "*" with "DD118". I am sure there is more to the error than that.
All help is appreciated.

You can use it mock library for testing file upload;
```
from unittest.mock import MagicMock
from django.core.files import File
mock_image = MagicMock(file=File)
mock_image.name="sample.png"
# Another test operations...
def test_file_upload(self):
# file_content is a bytest object
request = client.patch(
"/fake-url/",
{"file" : mock_image},
format="multipart",
)
```

Whenever you have a [mapped type](https://www.typescriptlang.org/docs/handbook/2/mapped-types.html) of the form `{[K in keyof T]: ⋯}`, with `in keyof` in there directly, it will be a *homomorphic mapped type* as described in https://stackoverflow.com/q/59790508/2887218. That means [`readonly`](https://www.typescriptlang.org/docs/handbook/2/objects.html#readonly-properties) and [optional](https://www.typescriptlang.org/docs/handbook/2/objects.html#optional-properties) properties in the input type will become readonly and optional properties in the output type. Optional properties will always include `undefined` in their domain.
So that means your `KeyPath<T>` type will end up including `undefined` if any of the keys of `T` (or perhaps even subkeys, given the recursion) are optional. You can test the type to see this (it looks like you tried to do this but didn't fully expand the type. One way to do this is to [intersect](https://www.typescriptlang.org/docs/handbook/2/objects.html#intersection-types) with `{} | null | undefined`, a type more or less equivalent to [`unknown`](https://www.typescriptlang.org/docs/handbook/2/functions.html#unknown)):
type TestKey = KeyPath<Domain> & ({} | null | undefined);
// ^? type TestKey = "id" | "value" | "user" | "user.id" | "user.name" |
// "user.emails" | "user.isActive" | "user.type" | "user.name.first" |
// "user.name.last" | undefined
Now, ideally, TypeScript would be smart enough to prevent you from using `undefined` as a key in an [indexed access type](https://www.typescriptlang.org/docs/handbook/2/indexed-access-types.html). But sometimes if generics are complicated enough, the compiler fails to see the problem:
type Hmm<T> = { [K in keyof T]: K }[keyof T]
type Grr<T> = T[Hmm<T>]; // <-- this should be an error but it's not
type Okay = Grr<{a: string}> // string
type Bad = Grr<{ a?: string }> // unknown
The `unknown` is what happens when the compiler is trying to figure out `{a?: string}[undefined]`. Allowing `undefined` to sneak in as a key is a known design limitation, according to [this comment on microsoft/TypeScript#56515](https://github.com/microsoft/TypeScript/pull/56515#issuecomment-1829898710), because trying to fix it was causing way too much breakage in real world code. So they allow it, and recommend that if you're writing a type function to extract keys, you should perform the following fix:
----
The recommended fix here is to use the `-?` [mapping modifier](https://www.typescriptlang.org/docs/handbook/2/mapped-types.html#mapping-modifiers) to make keys required in the mapping and to prevent `undefined` from being included in the domain. (The `-?` modifier is used in the definition of [the `Required<T>` utility type](https://www.typescriptlang.org/docs/handbook/utility-types.html#requiredtype)):
type KeyPath<T, TParentKey = undefined> = {
[K in keyof T]-?: K extends string ? (
// ^^
TParentKey extends undefined ? `${K}` : `${TParentKey & string}.${K}`
) : never; }[keyof T]
| {
[K in keyof T]-?: T[K] extends object ? (
// ^^
K extends string ? KeyPath<
T[K], TParentKey extends undefined ? `${K}` : `${TParentKey & string}.${K}`
> : never
) : never;
}[keyof T];
which removes `undefined` from the list of keys:
type TestKey = KeyPath<Domain> & ({} | null | undefined);
// ^? type TestKey = "id" | "value" | "user" | "user.id" | "user.name" |
// "user.emails" | "user.isActive" | "user.type" | "user.name.first" |
// "user.name.last"
which unbreaks `SortKey`:
type DomainSortKey = SortKey<Domain>;
/* type DomainSortKey = {
key: "id";
order: 'asc' | 'desc';
getter: Getter<Domain, "id">;
comparer: Comparer<number>;
} | {
key: "value";
order: 'asc' | 'desc';
getter: Getter<Domain, "value">;
comparer: Comparer<...>;
} | ... 7 more ... | {
...;
} */

I try to have a button to add ppl to the enlistment of a game. i have a function in another cog that updates the enlistment. so once someone press the button i want it to run that function it adds the person to a mySQL database and then the enlistment cog runs it and displays it on an message in the discord.
```
class reserve(commands.Cog):
def __init__(self, client):
self.client = client
class MyView(discord.ui.View):
@discord.ui.button(style=discord.ButtonStyle.success, label="Enlist me")
async def on_button_one_click(self, interaction: discord.Interaction, button: discord.ui.Button):
enlistment = self.client.get_cog("Embed") #This part is not working
await enlistment.enlistment(self) #This part is not working
```
This is the error i get
File "f:\SeaWolf\pythonbot\cogs\reserves.py", line 31, in on_button_one_click
enlistment = self.client.get_cog("Embed")
^^^^^^^^^^^
AttributeError: 'MyView' object has no attribute 'client'
I can load the function from other cogs doing the same thing but with a slash command instead of a button but i wanted to make it a bit easier with a button.

Please be gentle... I don't do much C++ and am trying to tidy up some code.... I'm trying to compile the code below in Arduino Studio, and it keeps throwing a `no matching function for call to 'devPort::devPort()'`
on the following line
` Sensor(String type, float adjustment, devPort port) {`
I've tried moving the devPort part to a new .cpp file and #include'ing it, but I get the same error.
I also tried
`Sensor(String type, float adjustment, devPort::devPort port)`
But still the same error.....
```
class devPort { // There will be 10 'Port's, all pre-defined as unavailable until the boardtype is known
public:
devPort(String name, int pin1, int pin2, int mode) {
this->name = name;
this->pin1 = pin1;
this->pin2 = pin2;
this->mode = mode;
}
String name;
int pin1;
int pin2;
int mode; // -1 = Disabled, 0 = SDA/SCL, 1=DAC, 2=ADC, 3=GPIO
};
// The 'Sensor's will be stored in the flash memory
class Sensor {
public:
Sensor(String type, float adjustment, devPort port) { // <--- This is where it complains
this->type = type;
this->adjustment = adjustment;
this->port = port;
}
String type; // Derived from *sensorTypes
float adjustment; // +/- adjustment value
devPort port; // Custom Port
};
```
I would expect that it should just allow this (and I've tried moving them above/below each other in case of linear compilation) |
