I am trying to make a strip plot where each row is colored by the variable "ident" and then the points change transparency based on variable "Pvalue" however I want to have a threshold where only points with pvalue <0.1 are colored the rest should be a light grey color.
So far I tried the following:
p = ggplot(da_results, aes(x=ident, y=logFC,color = ident)) +
geom_jitter()+coord_flip()+geom_point(alpha = da_results$PValue) + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), panel.background = element_blank(), axis.line = element_line(colour = "black"))+geom_hline(yintercept = 0)
which gives me everything except for the pvalue thresholds. |

I'm trying to make a localhost only webapp using Dash. I know things like electron exist for this, but I'm more comfortable with dash and pyinstaller for my internal application. I want to open something in a separate window and control it from another window and vice versa. I notice spotify is able to do this in open.spotify.com. They even have the time on a playing song synced in all the windows at once.
How are they doing it? Is it WebWorkers? |
How does spotify keep the track timer and controls synched across multiple browser windows? |

Firstly, rename `sort_object` to a relation-based name, rather than an action name, as more fitting for this bi-directional lookup (especially since there is no [sort][1] involved):
```prolog
object_basket(Object, Basket) :-
object(Object, Type),
basket(Basket, Type).
```
Then, can use [maplist][2]:
```prolog
?- Objects = [pencil, apple, eraser, book, mouse, mp3, ipad],
maplist(object_basket, Objects, Baskets).
Objects = [pencil, apple, eraser, book, mouse, mp3, ipad],
Baskets = [tall_basket, round_basket, tall_basket, tall_basket, red_basket, red_basket, red_basket].
```

Well one of the console log happens each time the button `onClick` callback is clicked, and the other is an unintentional side-effect, so there's no correlation really to the React component rendering to the DOM. Move that one into a `useEffect` hook to see/check the rendering behavior.
```jsx
import { useState, useEffect } from 'react';
export function App(props) {
const [count, setCount] = useState(1);
useEffect(() => {
console.log(count)
});
const clickHandle = () => {
console.log('handle');
setCount(1000);
}
return (
<div onClick={clickHandle}>click me</div>
);
}
```
See [Bailing out of a state update][1] from the legacy docs for explanation:
> If you update a State Hook to the same value as the current state,
> React will bail out without rendering the children or firing effects.
> (React uses the [Object.is comparison algorithm][2].)
>
> Note that React may still need to render that specific component again
> before bailing out. That shouldn’t be a concern because React won’t
> unnecessarily go “deeper” into the tree. If you’re doing expensive
> calculations while rendering, you can optimize them with **useMemo**.
Basically, if you enqueue a state update that is the same value/reference as the current state it may trigger one additional component rerender, but no more than this and it doesn't render deeper into the ReactTree.

For the SLT (set less than) instruction, according to the RISC-V instruction set architecture it should be implemented as the following:
" Place the value 1 in register rd if register rs1 is less than register rs2 when both are treated as signed numbers, else 0 is written to rd."
[![enter image description here][1]][1]
so review the ISA you tring to implement to know the correct way of implementing it.
if your ISA is similar to RISC-v, you should correct your 1- bit ALU to be:
module OneBitALU(a, b, cin, ainv, binv, less, op, result,
cout, set);
input a, b, cin;
input ainv, binv;
input less;
input [1:0] op;
output result;
output cout;
output set;
wire aneg, bneg;
reg result;
reg tmp;
reg set;
assign aneg = ainv ? ~a : a;
assign bneg = binv ? ~b : b;
assign less = (a>b)? 1'b1: 1'b0 ; // new line
FullAdder fulladder(aneg, bneg, cin, tmp, cout);
always @ (*) begin
case(op)
2'b00: result = aneg & bneg;
2'b01: result = aneg | bneg;
2'b10: result = tmp;
2'b11: result = less;
default: result = 1'b0;
endcase
end
endmodule

This can be handled in Angular on the component side instead of the html by using this routine.
- The reference to the collection is made
- A subscription to that reference is created.
- we then check each document to see if the field we are looking for is empty
- Once the empty field is found, we store that document id in a class variable.
First, create a service .ts component to handle the backend work (this component can be useful to many other components: Firestoreservice.
This component will contain these exported routines (see this post for that component firestore.service.ts:
https://stackoverflow.com/questions/51336131/how-to-retrieve-document-ids-for-collections-in-angularfire2s-firestore
In your component, import this service and make a private firestoreservice: Firestoreservice; reference in your constructor.
Done!
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
this.firestoreData = this.firestore.getCollection(this.dataPath); //where dataPath = the collection name
this.firestoreData.subscribe(firestoreData => {
for (let dID of firestoreData ) {
if (dID.field1 == this.ClassVariable1) {
if (dID.field2 == '') {
this.ClassVariable2 = dID.id; //assign the Firestore documentID to a class variable for use later
}
}
}
} );
<!-- end snippet -->

I am a pygame beginner and i was working on my first game after some training. I am making a clicker game in which you buy factories that generate revenue. The twist is that there are taxes and you have to manage resources to survive to the next day. The issue seems to be that the timer is detached and is located inside of a function however i don't know how and where to put it besides that place. I tried to put the function setup all over the place but it doesn't seem to affect it.
Note, this is my first post on stacks overflow so sorry for any issues with the question.

I am fairly new to PHP & laravel so looking for some assistance.
For example , i have a table in mySQL database that stores comments by a user. The values for this table are userId,bookId & Comment. I essentially want to build a function in my controller where it will retrieve a list of comments for a specific bookId. So if bookId 'cm123' has a total of 7 comments for that book , then my function should retreive all 7 comments with a HTTP GET request. This route is strictly going into the API route , we are not using any view for this ,so forms & such for input are not needed-- rather the parameters will be manually inputted when testing the request in Postman.
**Again , the end result i am aiming for is that the API returns a list of book comments stored in the database given a specific bookId input**
Below are my model , route & controller classes (I do already have a function for this called "SHOW" but it is not working) :
**Contoller**
```
<?php
namespace App\Http\Controllers;
use App\Models\CreateComment;
use App\Models\BookRating;
use Illuminate\Http\Request;
class BookRatingController extends Controller
{
/**
* Display the specified resource.
*/
public function show(string $bookId): View
{
return view('CreateComment.Comment', [
'Comment' => CreateComment::findOrFail($bookId)
]);
} // return list of comments
```
**Model**
```
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class CreateComment extends Model
{
use HasFactory;
protected $fillable =
[
'Comment',
'userId',
'bookId'
];
}
```
**Route**
```
<?php
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\BookRatingController;
use App\Http\Models\BookRating;
use App\Http\Models\CreateComment;

The error message you're encountering indicates an issue with node-gyp, which is used to build native addons for Node.js projects. Here's how to troubleshoot and potentially fix it:
Force Python 3 for node-gyp:
Set the PYTHON environment variable to your Python 3 executable path before running npm install:
export PYTHON=/path/to/your/python3 # Replace with actual path
npm install --save-dev parcel
Try reinstalling node-gyp globally:
npm uninstall -g node-gyp

I've just started to learn COBOL and I do not have idea what is a "COBOL way" to do that.
Obvious way in other programming languages will be to use some kind of map, but COBOL lacks such structures. COBOL arrays is out of question from performance reasons.
Other solution that comes to my mind is utilizing database, but it seems overkill for such trivial task.

I'm encountering a problem with scheduling Prometheus pods on AWS EKS Fargate within my Kubernetes cluster. Here are the details of my setup:
I have configured an AWS EKS Fargate profile named terraform_eks_fargate_profile_monitoring for my Prometheus namespace (monitoring). Here's the relevant Terraform configuration:
```
resource "aws_eks_fargate_profile" "terraform_eks_fargate_profile_monitoring" {
fargate_profile_name = "monitoring"
cluster_name = aws_eks_cluster.terraform_eks_cluster.name
pod_execution_role_arn = aws_iam_role.terraform_eks_fargate_pods.arn
subnet_ids = aws_subnet.terraform_eks_vpc_private_subnets[*].id
selector {
namespace = "monitoring"
}
}
```
I've deployed Prometheus using Helm with the following command:
```
helm install prometheus prometheus-community/prometheus -n monitoring

However, when I describe the pods, I receive the following warning:

I get this on all the node-exporter pods. The pushgateway and metrics pod runs fine
I'm not sure that the resource requests and limits specified in the Prometheus pod configuration are compatible with Fargate.
Since i used
```
helm install prometheus prometheus-community/prometheus -n monitoring
```
it has the default resource specifications for the Prometheus server container. |

I have also in

allure.properties file with:
```

```
I installed also:
```
npm install --save-dev allure-commandline
```
in project root directory .
At the end after executing command:
```
./gradlew clean build test
```
in intellij under windows
cucumber.html file is created but not allure report.
In directory
```

only 2 files appears:
```

Am I doing something incorrectly? Everything looks good.
**Edit:**
I tried to run exemplary solution ( https://github.com/allure-examples/allure-cucumber7-junit-platform-gradle-kts )
but it also ends without html file report in directory
build/allure-results , only few json files are created in this directory. |

```java
class Point {
private int[] components;
public Point(int... components) {
this.components = components;
}
public int getDimension() {
return components.length;
}
public int getComponent(int i) {
return components[i];
}
public void setComponent(int i, int v) {
components[i] = v;
}
}
```
### Sorting by axis
Indeed we need a comparator for this. In old school Java this is a bit of a ceremony - we have to write an `AxisComparator<Point>` class with an `axis` field which then compares based on component:
```java
class AxisComparator<Point> implements Comparator<Point> {
private int axis;
public AxisComparator(int axis) {
this.axis = axis;
}
public int compare(Point p, Point q) {
return Integer.compare(p.getComponent(axis), q.getComponent(axis));
}
}
```
You could then use this as `new AxisComparator(k)`.
In "modern" Java, you could get away with a one-liner:
```java
Comparator.comparingInt((Point p) -> p.getComponent(k));
```
[`Arrays.sort`](https://docs.oracle.com/javase/8/docs/api/java/util/Arrays.html#sort-T:A-java.util.Comparator-) accepts a comparator.
### `KdTree` class
We will want to distinguish between the tree - which stores a potentially `null` (in case of an empty tree) pointer to the root - and tree nodes. The tree nodes should get a recursive `private` constructor, taking the array and the axis we want to split on and producing a k-d-tree which splits on that axis. The tree should get a public constructor taking an array of points.
```java
class KdTree {
record Node(int axis, Node left, Node right, Point pivot) {
// Note: points is mutated (sorted by axis)
static Node build(Point[] points, int axis) {
if (points.length == 0)
return null; // empty node
Arrays.sort(points, Comparator.comparingInt((Point p) -> p.getComponent(axis)));
var mid = points.length / 2;
var leqPoints = Arrays.copyOf(points, mid);
var geqPoints = Arrays.copyOfRange(points, mid, points.length);
var nextAxis = (axis + 1) % points[0].getDimension();
return Node(axis, build(leqPoints, nextAxis), build(geqPoints, nextAxis), points[mid]);
}
}
private Node root;
public KdTree(Point[] points) {
root = Node.build(points.clone(), 0);
}
// Implement operations on your k-d-tree, like finding the nearest neighbor to a point here
}
```
### Better algorithms
This "naive" algorithm of sorting by an axis for each split is not ideal in terms of performance; it incurs O(n log n) costs at each of the O(log n) levels of the trees, resulting in O(n (log n)²), which is not bad, but also not optimal.
I have implemented all three approaches in Lua a while ago [here](https://github.com/TheAlgorithms/Lua/blob/61ec71e6e6458c5f773c7f36eafc95e6c63fce0d/src/data_structures/k_d_tree.lua). If you don't know Lua, read it as pseudocode.
#### Presorting
One option to optimize this is to *pre-sort* the points by each of the k axes, incurring costs of O(k n log n) for the pre-sorting, and then filtering the k pre-sorted lists into left & right parts as you split, incurring kn costs for each split, for a tree of depth O(log n), resulting in O(k n log n). This can be better than O(n (log n)²) if n is big and k is small (say, 2, 3 or 4).
To be more precise: What you pre-sort are either (pointers to) instances of a `Point` class, or indices (if you opt for the `PointArray`-based solution). So you end up with `k` pre-sorted arrays of `Point`s / `int` indices.
When you split, you *mark* all points left to the median. If you have an array of `Point`s, one approach would be to add a boolean `_marked` field to the `Point` class. This field then lets you filter the points along all other axes, splitting them into "marked" and "unmarked" points (except the pivot). For looser coupling, you would probably want to create a `MarkablePoint` class extending `Point` and convert all points to that initially (*before* presorting), or you might prefer a `HashSet` of marked points (by reference). For indices, you could also use a `HashSet`, or a boolean array.
#### Median of medians
The asymptotically optimal option is to use a *linear time* median selection algorithm ([median of medians](https://en.wikipedia.org/wiki/Median_of_medians)). Using this, you get O(n) costs for O(log n) layers, for a total of O(n log n).
### Out-of-band representation (low-level optimizations)
Representing an array of points as, well, an array of points *is* definitely the most idiomatic, straightforward, simple way to implement this in an OOP language like Java. I'd stick to this for an initial implementation unless you have a good reason not to. I would not prematurely optimize this.
As you said, you want to keep the components of a point together, and that is cumbersome to do if you store separate arrays of components.
But if you do have to optimize this at a low-level (maybe you have determined that the points eat up too much memory, or the heap allocation, GC or indirection overhead is too large or the cache locality is too bad) by using multiple arrays, write yourself something like a `PointArray` class which manages an array of k arrays of components. Sorting could simply sort a permutation of indices into these k arrays (well, after the first split of these indices, it is only a permutation of the restricted set of indices, but you get the idea).
This could look like this:
```java
class PointArray {
private int[][] points; // points[i][j] = i-th coordinate of j-th point
private int[] indices; // into points
public PointArray(int[][] points) {
this.points = points;
int n = points[0].length;
assert n > 0;
for (int i = 1; i < points.length; i++)
assert points[i].length == n;
indices = new int[n];
for (int i = 1; i < n; i++)
indices[i] = i;
}
private PointArray(int[] indices, int[][] points) {
this.indices = indices;
this.points = points;
}
public int getDimension() {
return points.length;
}
public int getLength() {
return indices.length;
}
public int getComponent(int pointIdx, int axis) {
return points[axis][indices[pointIdx]];
}
public Point getPoint(int i) {
var components = new int[getDimension()];
for (int axis = 0; axis < components.length; axis++)
components[axis] = getComponent(i, axis);
return new Point(components);
}
public void sortByAxis(int axis) {
Arrays.sort(indices, Comparator.comparingInt((int i) -> points[axis][i]));
}
// To slice the array, it suffices to slice the indices.
// We do not have to slice the points.
public PointArray slice(int from, int to /*exclusive*/) {
return new PointArray(Arrays.copyOfRange(indices, from, to), points);
}
}
```
Really this approach isn't all that different from having an array of points, except instead of pointers to heap-allocated points, we have indices into our "array-allocated" matrix of point coordinates. This requires some small changes to our k-d-tree:
```java
class KdTree {
record Node(int axis, Node left, Node right, Point pivot) {
// Note: points is mutated (sorted by axis)
static Node build(PointArray points, int axis) {
if (points.getLength() == 0)
return null; // empty node
points.sortByAxis(axis);
var mid = points.getLength() / 2;
var leqPoints = points.slice(0, mid);
var geqPoints = points.slice(0, points.getLength());
var nextAxis = (axis + 1) % points.getDimension();
return Node(axis, build(leqPoints, nextAxis), build(geqPoints, nextAxis), points.getPoint(mid));
}
}
private Node root;
public KdTree(int[][] points) {
root = Node.build(new PointArray(points), 0);
}
// Implement operations on your k-d-tree, like finding the nearest neighbor to a point here
}

I was wondering if there is a way to replace variables in PowerShell script block with their value that is defined in a scope. I also don't want to replace variables that are not available in the scope. My goal is to get a Script block that is "self contained" as much as possible.
```
$outerVariable = "hello"
$Command = {
Write-Host "$outerVariable"
$innerVariable = "world"
Write-Host "$innerVariable"
}
$Command = [scriptblock]::Create($ExecutionContext.InvokeCommand.ExpandString($Command.ToString()))
$Command
````
It results in:
```
Write-Host "hello"
= "world"
Write-Host ""
```
But I want this:
```
Write-Host "hello"
$innerVariable = "world"
Write-Host "$innerVariable"
``` |
PowerShell replace variables with their values defined in the context, but don't touch unknown variables |

How to make searchview works for find my dummy data |

I am trying to make a Menu filled with font styles for a particular font. In the code below I have one attempt that is commented out. The code just below correctly prints the styles but I can't get the ForEach() to work. GetFontStyles() seams to return an array of arrays and that internal array contains several fields including the font name, font style and some ID numbers. Note the member[1] which is was used to pull the style.
struct AddFontStyleItems: View {
var dm: DrawModel
init(_ dm: DrawModel ) { self.dm = dm }
var body: some View {
var fontStyles = getFontStyles(for: dm.curFont )
// ForEach(fontStyles, id: \.self) { curStyle in
// Button( "xxx" ) {
// print( "Style: \(curStyle)")
// // print("Type of Member: \(type(of: member)) - \(member[1])")
// }
// }
Button( "xxx" ) {
let fontStyles = NSFontManager.shared.availableMembers(ofFontFamily: dm.curFont)
print("-\nFont: \(dm.curFont)")
if let members = fontStyles {
for member in members {
print("Style for: \(dm.curFont) - \(member[1])")
}
}
}
}
}
func getFontStyles(for fontFamily: String) -> [String] {
let fontManager = NSFontManager.shared
guard let availableMembers = fontManager.availableMembers(ofFontFamily: fontFamily) else {
return []
}
return availableMembers.compactMap { member in
return member as? String
}
}

Put a for loop iteration in a Bootstrap group list button click
I have a lab about addEventListener, where in a click of a button shows your for loop with office locations.
const grupList = document.querySelector("ul");
console.log(grupList);
const listItems = document.querySelector("li");
console.log(listItems);`
const offices = document.getElementById("ofLocations");
let officeLocations = ["New York", "London", "Paris", "Tokyo", "Sydney"];
```function getOfficeLocations (arr){
``` for (let i = 0; i < arr.length; i++) {
`console.log(arr[i]);
```offices.addEventListener("click", getOfficeLocation {
})
}
}
`getOfficeLocation(officeLocations);`
This is what I have done so far. |

We have a K8s cluster where for communication/networking we are using istio's service mesh which has mTLS enabled. Currently there is no such authentication between any services in our cluster, thus any service can call any other service within a cluster.
So my doubt is somehow if one of my container's security is compromised will mTLS helps in stopping lateral attack in other pod? As per me same is not possible only with mTLS and we will need some other way may be explicit authentication b/w services or network policy.
Any doc/reference will be helpful. |

I am debugging a crash and i see following behaviour -
When i attach GDB to the process and do info registers, i see the following value for esp -
esp 0xfd2475d0 0xfd2475d0
Upon doing a disassembly of code where it is crashing, I see it's storing to memory pointed-to by the stack pointer -
81c886a: c7 04 24 2c f9 8a 0c movl $0xc8af92c,(%esp)
And if i view maps file in `/proc/<PID>/maps`, I see stack address range as -
fff39000-fff59000 rwxp 7ffffffde000 00:00 0 [stack]
Clearly, value of `ESP 0xfd2475d0` in GDB is not in sync with the stack address in maps file.
Can this be a reason for crash. I think it should be as i am getting SIGSEGV. Also, how do I resolve this issue? |

I have an array declared above the beginning of a for loop as: `$array = array();`.
Now, in the for loop I start inserting values into it.
At some point I make one of its index as another array as `$array[$j]=array();`
And insert some values like, `$array[$j][$l] = id;` and so on.
Now, when I use `print_r($array);` inside the loop I get the expected value of the array.
But outside the loop this newly created array (2-D) is getting lost and I am getting only a 1-D array as an output.
Can someone please tell me where the problem could lie? |
This is considered as anti pattern in modern React ecosystem.
According to single responsibility principle
keep your business logic in a simple way with custom hooks (Use prototype inheritance in it, if required), To store API calls use Tanstack Query and to store global data use Jotai (Atoms). This libraries are very easy to learn and maintain.
You don't need to write Redux (action, reducers and store), Redux toolkit and other boilerplate codes today. Even you learn this concepts it was not so useful in other stacks.
Even today many React interviewers asks for Redux questions, I hope they will update their projects with the mentioned best practices soon. |
This can be handled in Angular on the component side instead of the html by using this routine.
- The reference to the collection is made
- A subscription to that reference is created.
- we then check each document to see if the field we are looking for is empty
- Once the empty field is found, we store that document id in a class variable.
First, create a service .ts component to handle the backend work (this component can be useful to many other components: Firestoreservice.
This component will contain these exported routines (see this post for that component firestore.service.ts:
https://stackoverflow.com/questions/51336131/how-to-retrieve-document-ids-for-collections-in-angularfire2s-firestore
In your component, import this service and make a private firestore: Firestoreservice; reference in your constructor.
Done!
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-html -->
this.firestoreData = this.firestore.getCollection(this.dataPath); //where dataPath = the collection name
this.firestoreData.subscribe(firestoreData => {
for (let dID of firestoreData ) {
if (dID.field1 == this.ClassVariable1) {
if (dID.field2 == '') {
this.ClassVariable2 = dID.id; //assign the Firestore documentID to a class variable for use later
}
}
}

I'm trying to create a test to check the correct behaviout of my service object,
```ruby

pp message
response = connection.post do |conn|
conn.url url
conn.body = message
conn.headers = @headers
end
check_response(response)
end
...
```
this is the test :
```ruby
test "create a title" do
body = { "name" => 'some name',
"external_id" =>'004',
"title_type" =>'feature',
"tags" => 'some tag' }.to_json
puts body
stub_request(:post, "some web")
.with(body: body )
.to_return(status: 201, body: "Created", headers: {})
response = MovidaApi.new(payload).create_title
assert response.success?
assert_equal "Created", response.body
end
...
```
The problem comes when I include the `.with` in the stub, (without it's working ok),
I printed statements and the output are exactly the same.
The error is:

The problem is that I'm not importing any function named "library" from the "foreach" namespace. What is more, if I'm not wrong, the "library" function comes from the "base" package, so I don't understand why I'm getting this error. My NAMESPACE file looks like this:

I've looked all over the internet for a solution and tried to update the "foreach" package to it's latest version but to no avail. What is more strange is that if I delete these lines:
```
importFrom(foreach,"%dopar%")
importFrom(foreach,foreach)
```
from the NAMESPACE file I still get the same 'library' is not an exported object from 'namespace:foreach' error.
Have somebody else found this problem?

This CORS thing can be a headache to set especially for the first time. But by being precise you can do.
In your `Program.cs` file, make the following change. Notice that there are two changes to be made one above and another below the `var app = ...` statement:
```
builder.Services.AddCors(policyBuilder =>
policyBuilder.AddDefaultPolicy(policy =>
policy.WithOrigins("*").AllowAnyHeader().AllowAnyMethod())
);
var app = builder.Build();
app.UseCors();
```
If you are specifying an actual origin, make sure you include the `http` part for example:
```
...
policy.WithOrigins("http://localhost:3000")
```
Your web browser code making the request should also be in point. Here is the request in javascript using axios:
```
import axios from "axios";
const api = 'http://localhost:5000'
/**
*
* @returns {TransferHeader[]}
*/
export const fetchTransfers = async () => {
const { data } = await axios({
method: 'get',
url: `${api}/api/transfers`,
// withCredentials: true
})
console.log(data)
return data
}
```

I want to make the effect of the scrollview moving along when the view pops up like this：
[](https://i.stack.imgur.com/f68Kg.gif)
However, when I scroll the scrollview to the bottom, the following effect occurs：
[](https://i.stack.imgur.com/V6L3Z.gif)
I don't know why the value passed into setContentOffset is different from the contentOffset.
ScrollViewWrapper<Content: View>: UIViewRepresentable：
```
public func makeUIView(context: UIViewRepresentableContext<ScrollViewWrapper>) -> UIScrollView {
let view = UIScrollView()
view.delegate = context.coordinator
view.clipsToBounds = false
view.contentInsetAdjustmentBehavior = .never
// Instantiate the UIHostingController with the SwiftUI view
let controller = UIHostingController(rootView: content())
controller.view.translatesAutoresizingMaskIntoConstraints = false // Disable autoresizing
view.addSubview(controller.view)
// Set constraints for the controller's view
NSLayoutConstraint.activate([
controller.view.leadingAnchor.constraint(equalTo: view.leadingAnchor),
controller.view.trailingAnchor.constraint(equalTo: view.trailingAnchor),
controller.view.topAnchor.constraint(equalTo: view.topAnchor),
controller.view.bottomAnchor.constraint(equalTo: view.bottomAnchor),
controller.view.widthAnchor.constraint(equalTo: view.widthAnchor)
])
return view
}
public func updateUIView(_ uiView: UIScrollView, context: UIViewRepresentableContext<ScrollViewWrapper>) {
let newoffset = CGPoint(x: 0, y: self.contentOffset.y + uiView.contentOffset.y)
if newoffset.y > self.contentOffset.y{
uiView.setContentOffset(newoffset, animated: true)
}
}
```
ContentView
```
VStack(spacing:0){
Color.blue
.opacity(0.8)
.frame(height: 100)
.zIndex(1)
ScrollViewWrapper(contentOffset: $contentOffset, scrollViewHeight: $scrollViewHeight, visibleHeight: $scrollViewVisibleHeight) {
VStack {
ForEach(1..<51, id: \.self) { index in
Text("Item \(index)")
.padding()
.frame(maxWidth: .infinity, alignment: .leading)
}
}
.background(.green)
}
Button("test"){
withAnimation(.bouncy){
pop.toggle()
contentOffset = CGPoint(x: 0, y: pop ? 250 : -250)
}
}
.frame(maxWidth: .infinity, maxHeight: pop ? 300 : 50)
.padding(10)
.background(.black)
.opacity(0.8)
}
.ignoresSafeArea(.all)
.background(.red)
}
```
Edit:
I found that there is no any issue when ```setContentOffset(_, animated: false)```, and ```withAnimation() set to nil```.
Is there any solution with animation? |

I process a TEXT log file that contains, among other items, date in this form: 'January 20, 2021 5:26:19 pm'.
I don't have zone information. The system runs in complete isolation, such as offline mode, or no connectivity to the internet. Zero connectivity to the outside world.
I want to save this information to the database for further time comparison such look at logs which are greater than this time.
So, I save it to the POSTGRES database in a column of type timestamp.
When needed I retrieve from database convert to LocalDataTime and use it.
What is the right way or better way of saving this information to the database? |
