so in an intro to AI course we where given a project to find the optimal route using search algorithms to a relevant hospital in a certain city, and we are asked to consider the map of the hospitals in this city, i have a problem of how to select the initial state it sure is the patient localization but how can i incorporate it into my search graph which is the map of hospitals dynamically (im thinking that localization is in long/lat format)
i thought of a dynamic graph but i can't see how can i incorporate the patient localization dynamically |

[zett42](https://stackoverflow.com/users/7571258/zett42) has provided the crucial pointer:
From the [`ConvertFrom-StringData`](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/convertfrom-stringdata) help topic (emphasis added), as of PowerShell 7.4.x:
> `ConvertFrom-StringData` supports escape character sequences that are allowed by conventional machine translation tools. That is, the **cmdlet can interpret backslashes (`\`) *as escape characters* in the string data** [...] You **can also preserve a literal backslash in your results by escaping it with a preceding backslash, like this: `\\`**. Unescaped backslash characters, such as those that are commonly used in file paths, can render as illegal escape sequences in your results.
Therefore, **assuming that all `\` characters in your input file are meant to be interpreted _literally_**:
```
(Get-Content -Raw C:\<ConfigFolder>\basic.conf).Replace('\', '\\') |
ConvertFrom-StringData).FileLocation
```
Note the use of `-Raw` with [`Get-Content`](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.management/get-content) to ensure that the file content is read _in full_, as a single, (typically) _multiline_ string, which in turn ensures that `ConvertFrom-StringData` outputs a _single_ `[hashtable]` instance.
(If, by contrast, you really mean to output a separate hashtable _for each input line_, omit `-Raw`).
---
Given that this escaping need may be inconvenient (and possibly somewhat unexpected, but that cannot be helped), **it would be helpful if `ConvertFrom-StringData` itself supported _verbatim_ (literal) parsing by way of an _opt-in_**:
* [GitHub issue #20418](https://github.com/PowerShell/PowerShell/issues/20418) asks for just that, by way of a future `-Raw` switch. This enhancement has been green-lit, but is yet to be implemented. |
To display the legend outside of the plot in matplotlib, you can use the bbox_to_anchor papameter along with the loc parameter of the legend function, here's how you can modify your code to achieve that:

The relevant part of [the documentation](https://doc.rust-lang.org/std/fs/fn.rename.html) is this:
> On Unix, if […] `from` is not a directory, `to` must also be not a directory. In contrast, on Windows, `from` can be anything, but `to` must not be a directory.
I.e. `to` *may not be* a directory, but you've passed the name of a directory to the second parameter.
So you'll have to append the file name to the directory name yourself:
```rust
let mut file_path = PathBuf::from("apps/a");
let mut destination_path = PathBuf::from("apps/test/");
destination_path = destination_path.join(file_path.file_name().unwrap());
let result = fs::rename(file_path, destination_path).unwrap();

I stumbled on this class when browsing the internet this morning: [`CStrBufT`][1].
I understand that it is meant to be used instead of:
```cpp
CString::GetBuffer
CString::GetBufferSetLength
CString::ReleaseBuffer
```
But the documentation lacks a usage example, and my searches on the internet don't seem to show this class being used, but the respective `CString` methods.
What is the correct way to use this wrapper when you need a buffer?

i have problem in Google Colab Deep Learning coding any one help me about this issue Chat GPT fail to solve my error |
Extracting the value of CSS Property directly from Stylesheet doesn't seem to be the right thing to do. I say this because the value of a property might change when multiple CSS files work together to bring the final value of any class's property.
Consider the case where StyleSheetA, and StyleSheetB both have `sample-class`, and one sets `font-size` to `2em` while the other sets it to `3em`. In this case which value do you want? Do you know which one will be applied on any element, what if one of them marks it as `!important`?
If you just want to access the final CSS property for any element, consider using [getComputedStyle][1] instead.

I have created a custom SAML application in the Google Admin panel for my workspace account to allow users to login via SSO to an application using their Google Workspace credentials. Currently only users of my organisation can login to this application. I want to make it so that users of an external organisation can also login to this application using their Google Workspace credentials using SSO. How do I do this?
Tried:
I have created a Google Group and all users who should have access to this application (both internal and external organisation users) and turned on access to this Google Group in the access settings of the custom SAML app.
Expected:
Both internal and external users should have access to the application.
Result:
Only internal users are able to login to the application using their credentials. |

Here I have hardcoded some stuff because I was trying things out. Inside "passport.use" i have hardcoded user object, so that the callback function in "passport.authenticate" should always receive user object and print "user found successfully".
But for some reason the opposite has been happening and "user not found" has been printing on the webpage.
I tried `console.log(user)` inside the "passport.authenticate" and found that the callback function has not received user object or error . So i tried `console.log("123")` inside passport.use and found that when "local" function is called from "passport.authenticate" the "passport.use" is never being called or invoked for some reason.
EDIT: okay I've found that the problem was in synatx as is replaced
```
passport.use(new localStrategy(
async (email, password, done) => {
try {
const user = { email: "piyu", password: "123" };
return done(null, user);
} catch (err) {
return done(err);
}
}));

Instead of using a `ZStack`, try showing the yellow circle as an overlay over the `Image`. This way, the size and position of the circle will always correspond to the size and position of the image.
- If the `.scaleEffect` is applied after the green background and the overlay, these will be scaled too.
- The blue background can be applied using another `.background` modifier to the `Image`. To fill all of the screen background, set a frame with `maxWidth: .infinity, maxHeight: .infinity`.
- When you update the flag `isAnimating`, you can either do it `withAnimation`, or you can add an `.animation` modifier to the `Image`.
```swift
NavigationStack {
NavigationLink("Show image") {
Image(poke.imageUrl)
.resizable()
.aspectRatio(contentMode: .fit)
.padding()
.clipShape(Circle())
.background(Circle().fill(Color.green))
.overlay {
Circle()
.stroke(Color.yellow, lineWidth: 3)
// .scaleEffect(animationAmount)
.opacity(Double(2 - animationAmount))
.animation(.easeInOut(duration: 2).repeatForever(autoreverses: false), value: animationAmount)
}
.scaleEffect(isAnimating ? 1.2 : 1.0) // 이미지 크기 조절
.rotationEffect(.degrees(isAnimating ? 10 : 0)) // 이미지 회전
.shadow(radius: 8)
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(.blue)
.animation(.easeInOut(duration: 2).repeatForever(autoreverses: false), value: isAnimating)
.onAppear {
isAnimating = true

You change `display` of `td` thus breaking its `display: table-cell`.
Just select a different way, for example, position the input absolutely or add a wrapper DIV:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-css -->
td{
border: 1px solid gray;
width:100px;
height:40px;
}
.checkbox-cell{
position:relative;
}
.checkbox-cell input{
position: absolute;
top:50%;
left:50%;
margin-top:-6px;
margin-left:-6px;
}
.checkbox-cell2{
position:relative;
}
.checkbox-cell2 > div{
position: absolute;
inset: 0;
display:flex;
align-items: center;
justify-content: center;
}
<!-- language: lang-html -->

<tr><td class="checkbox-cell"><input type="checkbox"></td></tr>
</table>
<table>
<tr><td class="checkbox-cell2"><div><input type="checkbox"></div></td></tr>
</table>
<!-- end snippet -->

The state is not changing when the focus is changed, therefore the text color doesn't change.
You must listen to the `FocusNode` changes and `setState` after any changes. Update your widget like this:
```dart
FocusNode emailText = FocusNode();
Color _emailTextColor = Colors.black;
_onEmailFocusChange() {
setState(() {
_emailTextColor = emailText.hasFocus ? Colors.blue : Colors.black;
});
}
@override
void initState() {
emailText.addListener(_onEmailFocusChange);
super.initState();
}
@override
void dispose() {
super.dispose();
emailText.removeListener(_onEmailFocusChange);
emailText.dispose();
}
```
Use `_emailTextColor` as your text color inside `TextStyle`. |
YES, Organization structured data is like a special tag we can add to our website to tell search engines more about our organization. It helps them understand who we are and what we do, which can make our website more visible to people searching online. So yeah, having Organization schema on every page is a good idea because it helps search engines connect better with our site. |
I am looking for an operation that creates a matrix from a colwise operation in Eigen.
I could not find an appropriate operation in [VectorwiseOp](https://eigen.tuxfamily.org/dox/classEigen_1_1VectorwiseOp.html) (sorry if I overlooked one).
It seems that it is supported for some operations. First output compiles fine, second output gives an error. (https://www.godbolt.org/z/qrrfa1brx)
```c++
#include <Eigen/Core>
#include <iostream>
int main() {
Eigen::Matrix3d m;
m << 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0;
std::cout << m + m.rowwise().sum().replicate(1, 3) << std::endl; // OK
std::cout << m + m.rowwise() << std::endl; // Failure: operator + not found.
}
```
In the context I want to apply this, it is not possible for me to use `rowwise` as an lhs operator. I want to apply other matrix operations on the result.
Maybe an `matri()` or `array()` method in the `VectorwiseOp` would solve this gap. |

The default headers are explicitly added by Netty when a request is prepared for sending. The main point of interest is here:
```java
// io.netty.handler.codec.http.HttpHeaders
public interface HttpHeaders extends Iterable<Map.Entry<String, String>> {
HttpHeaders add(String name, Object value);
// ...
}
```
As you might know, Spring's `WebClient` uses Project Reactor and Netty under the hood for making web requests. When you create a `WebClient` instance and build a request with it, the headers do not appear immediately. However, once the request is about to be sent out (when Netty's `HttpClientOperations` comes into play), Netty adds these default headers (like HOST, Accept-Encoding, etc) even if none were explicitly set by you.
Here's a look into part of `HttpClientOperations` from Netty on GitHub:
```java
// io.netty.handler.codec.http.HttpClientOperations
@Override
protected void onOutboundSubscribe(Subscriber<? super ByteBuf> s) {
if (!HttpRequestEncoder.encoderHeader(headers(), method(), uri())) {
if (log.isDebugEnabled()) {
log.debug(format(ctx.channel(), "Dropped {}"), this);
}
return;
}
//...
}
```
The `HttpRequestEncoder.encoderHeader(...)` part is where the headers are prepared and added if they don't exist. You might take a look at the `encodeHeaders` method too for deeper insights.
Here is the point-in-time in `HttpClientOperations` where headers are added:
```java
// io.netty.handler.codec.http.HttpHeaders
public interface HttpHeaders extends Iterable<Map.Entry<String, String>> {
HttpHeaders add(String name, Object value);
// ...
}
```
Unfortunately, `WebClient` does not provide an out-of-the-box solution to prevent Netty from adding these headers. However, you can create a custom filter and add it to your `WebClient` to intentionally remove these headers each time a request is built:
```java
WebClient.builder()
.baseUrl("https://httpbin.org")
.filter((clientRequest, next) -> {
ClientRequest mutatedRequest = ClientRequest.from(clientRequest)
.headers(httpHeaders -> {
httpHeaders.remove("Host");
// remove other headers if needed
})
.build();
return next.exchange(mutatedRequest);
})
.build()
.get()
// continue with your code for .uri, etc.
```
This way, each time you build a request, the filter will remove the Host header (and others if you wish) before sending it off. Please note that this might not be the best practice as some servers might require the `Host` header or others for processing the request. |
Creating a Google Login-In Extension for a personal project so I've set up funtionality that allows me to log in to the extension with my Google account and it works. I'm using an initial HTML file called "popup.html" to hold the logic of Google's Authentication by calling "popup.js" as the backend script, displaying a "Waiting for Log-in" message, and then setting that <div> attribute to display the contents of another HTML file called "authorized.html" after succesful sign-in by setting its contents as the innerHTML property of "popup.html". The issue is that "authorization.html" own script "authorized.js" will not print anything to either my console nor will it even throw an error on the console despite the other contents of "authorized.html" succefully being displayed. Only the relevant parts of my code are below but I'd like to know why I'm having this issue and how to circumvent it. Thank you
popup.html:
```
<!DOCTYPE html>
<html>
<head>
<title>Google OAuth Sign-In</title>
<script src="popup.js"></script>
</head>
<body>
<div id="Sign-In TempUI" class="content-body">Waiting for Google Sign-In</div >
</body>
</html>
```
popup.html:
```
console.log('popup.js loaded');
document.addEventListener('DOMContentLoaded', function () {
const NewGUI = document.getElementById('Sign-In TempUI');
chrome.identity.getAuthToken({ interactive: true }, function (token) {
if (chrome.runtime.lastError) {
console.error(chrome.runtime.lastError.message);
return;
}
console.log('Token acquired:', token);
loadAuthorizedUI(token);
});
function loadAuthorizedUI(token) {
console.log('Debug:', token);
fetch('authorized.html')
.then(response => response.text())
.then(html => {
console.log('HTML content:', html);
NewGUI.innerHTML = html;
})
.catch(error => console.error('Error fetching or processing HTML:', error));
}
});
```
authorized.html:
```
<!-- Page Displayed after recieving token from OAuthetication. Should display GUI for Email handling -->
<!DOCTYPE html>
<html>
<head>
<title>Authorized UI</title>
</head>
<body>
<h1>Welcome! You are now authorized.</h1>
<ul id="emailList">
</ul>
<script src="authorized.js"></script>
<div>Hit end</div>
</body>
</html>
```
authorized.js:
```
//throw new Error('This is a test error from authorized.js');
console.log('authorized.js loaded');
```
I'm using Chrome DevTool to dubug so before I was starting another document.addEventListener('DOMContentLoaded', function ()) and then trying to replace the contents of emailList after trying to get its element by Id, but it wont even open authorized.js. Console.log doesnt print anything and the exception doesnt actually display anything on the console. However when I move the authorized.js script to popup.html, it'll suddenly display albiet errors. My biggest confusion is that "<h1>Welcome! You are now authorized.<h1>" and "<div>Hit end</div>" will display on my GUI but the script wont even print, as if its skipping it |

I'm using Premake to manage the build configuration of my project, which consists of two static libraries ("Engine" and "Game") and an executable ("Launcher"). But when I attempt to integrate/link GLFW into my Engine library, I'm encountering linking errors.
I should mention I'm trying to link GLFW statically. I'm also using visual studio 2022 on a windows platform.

I'm new to using Premake, so I'm not entirely sure what I'm doing wrong. I've noticed that some developers integrate GLFW directly as a project within their solution, but if possible I would like to avoid that since I'm planning on adding additional libraries in the future and want to avoid the bloat.

I'm trying to simulate the CSMA/CD protocol using ns3 software for a course project. However, after installing ns3, I've checked the official documentation and asked the teaching assistant, but I couldn't find specific implementation details.
I even saw some answers stating that ns3 does not support simulating collision detection and backoff logic. Is this true? If not, how can I implement the CSMA/CD protocol in ns3? |

No, this is not possible. Quarto contains tools to generate PDF, but not to parse PDFs. The latter would be required to include PDFs the way you imagine, adjusted to the style of the document. The [pdfpages](https://www.ctan.org/pkg/pdfpages) package (of which you already mentioned the `\includepdf` command) is likely the closed you can get. |

Three bugs that I can see, including some spotted in comments.
----
```
MOV AH, 09H
LEA AX, msg3
INT 21H
```
Looks like a typo for `LEA DX, msg3`. As it stands you will have a random value in AH (the high byte of the address of `msg3` and will be executing some random DOS function. That might be what crashes DosBox.
Also, more efficient than `LEA` here (and in the other similar instances) would be `MOV DX, OFFSET msg3` which has the same effect and saves one byte.
----
```
XOR AX, AX
MOV DX, 10H
DIV DX
```
First, you zeroed out `AX` thus discarding the total value you so carefully computed (remember, `AX` emcompasses both `AH` and `AL`). Second, `DIV r/m16` is a 32 by 16 bit division: it divides the 32-bit unsigned value in `DX:AX` by the value in `r/m16`, with the quotient placed in `AX` and the remainder in `DX`. So here you are dividing `100000H` by `10H`; the quotient is `10000h` which overflows 16 bits, and so you will get a divide overflow exception.
This could also be the cause of the crash, though I seem to recall that real MS-DOS had a handler for the divide overflow interrupt that would print a message and terminate the program, without crashing the system. I'm not sure if DosBox provides that, however.
Anyway, I think you probably meant
```
XOR AH, AH ; zero-extend AL into AX
MOV DL, 10H
DIV DL
```
to do a 16 by 8 bit divide of the number from `AL` (extended with zeros to produce a 16-bit value in `AX`) by `10H`, placing the quotient in `AL` and the remainder in `AH`.
----
```
MOV AH, 02H
MOV DL, Q
INT 21H
```
You need to add `0` to the values `Q` and `R` to create printable ASCII characters for output. |
Given this example...
{
"A-B": {
"x": {
"name": "x A-B"
},
"y": {
"level": 6
}
},
"B-C": {
"x": {
"name": "x B-C"
},
"y": {
"level": 9
}
},
"A-C": {
"x": {
"name": "x A-C"
}
}
}
Where "A", "B" and "C" are states and "x" and "y" are different dicts. "x" can have a "name" key with a string value amd "y" can have a "level" key with an integer value.
Both "x" and "y" are optional.
I've create the schemas for "x" and "y"...
def X_Schema( Schema ):
name = fields.String( required = True )
def Y_Schema( Schema ):
level = fields.Integer( required = True )
I know I need to use some nesting but I can't work out how this is going to work when the top level "key" is not fixed. i.e. it can be "A-B", "A-C", "B-C" etc. "x" and "y" can only occur once within a top level value, both are optional.
I'd like to do something like...
def StateSchema( Schema ):
???? = fields.Dict( keys = < "x" or "y" >, values = <X_Schema or Y_Schema> )
Personally, I don't think this is possible using marshmallow. I do not control this input so I'm pretty much stuck not validating it if can't be done using marshmallow.
I've got this far...
class StateSchema( Schema )
a_b = fields.Dict( keys = fields.String(), values = fields.Nested( X_Schema() ), required = False, data_key = "A-B" )
b_c = fields.Dict( keys = fields.String(), values = fields.Nested( X_Schema() ), required = False, data_key = "B-C" )
but I feel this is sub-optimal as I need to create fields for all of the possible states.... :(

Switch to v3 :) v3 came up because v2 was relatively easy to hack with ia the method you mentioned, and generally weak. That's why it hasn't been, most likely, updated for new strategies of robots.
When you do the switch, you'll be able to set the minimum trustworthiness threshold in reCAPTCHA v3 admin console. |

First of all, your `useImage` hook is not doing anything except loading the image, then set a state. If this is only for demonstration purposes, that's fine, otherwise, you should look into what you are trying to achieve with that hook.
Regarding the test, if you are using `jest` and `jsdom` to test. Then `jsdom` [only fire load events when they actually load something][1]. Meaning you must use a real image in the `src` AND change some jest configuration like this:
In `package.json`, if you use jest.config.js, then please refer to the official doc for the equivalent.
"jest": {
"preset": "ts-jest",
"testEnvironment": "jsdom", // we need this line
"transform": {
"node_modules/variables/.+\\.(j|t)sx?$": "ts-jest"
},
"testEnvironmentOptions": {
"resources": "usable" // we need this line
},
"transformIgnorePatterns": [
"node_modules/(?!variables/.*)"
]
},
You'll also need to install [canvas][2]
npm i canvas
Then your test is going to pass now. But, if you find this is a bit problematic to install a new dependency and change how the default test framework works, then you can [mock the Image object implementation][3] instead, personally, I would prefer this way:
const LOAD_FAILURE_SRC = 'LOAD_FAILURE_SRC';
const LOAD_SUCCESS_SRC = 'LOAD_SUCCESS_SRC';
beforeAll(() => {
Object.defineProperty(global.Image.prototype, 'src', {
set(src) {
if (src === LOAD_FAILURE_SRC) {
setTimeout(() => this.onerror(new Error('mocked error')));
} else if (src === LOAD_SUCCESS_SRC) {
setTimeout(() => this.onload());
}
},
});
});

I've successfully installed Node.js and NPM on my machine, but I'm encountering an issue when trying to create a new React Native app. After entering the command in the terminal, nothing happens, despite having a stable internet connection. Can anyone provide guidance on how to troubleshoot and resolve this issue? Your assistance would be greatly appreciated, and sharing any insights could benefit others facing similar challenges.
Thank you in advance!

I am plotting histograms showing distributions of an angle `tau`. I used a random normal distribution as shown:
import numpy as np
N = 100000
tau = np.arccos(np.random.normal(-1, 1, N))
I got the error `"RuntimeWarning: invalid value encountered in arccos tau = np.arccos(np.random.normal(-1, 1, N))"`.
This did not pop up with a uniform distribution.
Why did this happened with the normal distribution? |

I'm currently working on optimizing a kernel, and one of the most time-consuming loops, despite optimization efforts, still accounts for 80% of the benchmark's execution time. The loop's performance bottleneck stems from its memory-bound nature, primarily due to an indirect memory access pattern that hampers prefetching. I'm seeking guidance on how to hint to the compiler to perform indirect prefetching without compromising other optimizations.
Here's the relevant snippet of the source code:
```
for (j = 0; j < lastrow - firstrow + 1; j++) {
sum = 0.0;
for (k = rowstr[j]; k < rowstr[j+1]; k++) {
sum = sum + a[k] * p[colidx[k]];
}
q[j] = sum;
}
```
The bottleneck arises from the indirect memory access pattern, particularly in accessing the `p` array at the `colidx[k]` position.
After compiling with the Intel compiler using the following flags:
`-O3 -xhost -mcmodel=medium -qopt-prefetch=5 -xCOMMON-AVX512`
It seems the compiler unrolled the loop by 8-factor, vectorized and added some prefetch instructions due to high `qopt-prefetch` level.
```
Block 1:
vmovupdy (%r11,%r10,4), %ymm15
kxnorw %k0, %k0, %k1
vpxord %zmm16, %zmm16, %zmm16
vgatherdpdq (%r9,%ymm15,8), %k1, %zmm16
vfmadd231pdz (%rbx,%r10,8), %zmm16, %zmm14
prefetcht0z 0x900(%rbx,%r10,8)
prefetcht0z 0x480(%r11,%r10,4)
add $0x8, %r10
cmp %rsi, %r10
jbe 0x403370 <Block 1>
```
I've experimented with hints and tried using the volatile keyword, but it seems like I'm forced to choose between vectorization and prefetching `p[colidx[k+PREFETCH_FACTOR]]`. However, I believe it's possible to leverage both for optimal performance.
Would appreciate any insights or suggestions on how to achieve this balance. Thank you! |
I'm working on a Symfony project where I need to generate PDF files from HTML templates that include a map element. However, I'm having trouble centering the map element on the PDF without using any specific PDF generation tools or libraries.
I have a Twig template called carte.html.twig that contains the map element. I want to position the map element in the center of the PDF page. I've tried adjusting the CSS styles within the template, but the map element doesn't appear centered on the generated PDF.
Here's a simplified snippet from my carte.html.twig template:
```
<!DOCTYPE html>
<html>
<head>
<style>
/* CSS styles for the map element */
#map {
/* Styles for the map */
}
</style>
</head>
<body>
<div id="map">
<!-- Map content goes here -->
</div>
</body>
</html>
```
(https://i.stack.imgur.com/mE6fU.jpg)
I'm seeking guidance on how to properly center the map element on the PDF generated from this Twig template without relying on any specific PDF generation tools or libraries. Are there any alternative approaches or techniques that I can use to achieve this?
Any help or suggestions would be greatly appreciated. Thank you! |

Suppose A is a symmetric matrix whose SVD is A= USV^T, and let B = U\sqrt{S}V^T, then B^2 should be equal to A.
But when I implemented it using tensorflow, B^2 and A does not match. Highly appreciated if you could give some advice! |

It is expected that your code throws an error. [As indicated in the "state" property of StateNotifier][1] it is `@protected` and `@visibleForTesting`, which implies that it can only be accessed from child classes and test.
As recommended by the Riverpod documentation, if you want to reactively get a provided value, i.e. rebuild you widgets on changes of the provider, you shall use "watch" instead of "read".
```dart
final value = ref.watch(myCustomStateProvider);
```

I am busy with creating a REST API where you can load company details and then load products for each company each with their own enpoint
POST /company-details
POST /products
Company details have a request body
companyName
uniqueCode
description
contact
location
Products has a request body
uniqueCpyCode
productName
skuNo
Each one will create a record with an auto generated id in a MySQL db. Then I also have a delete endpoint to delete products ( i also have one for companies)
DELETE /products/{id}
One of the issues i have, i want users to delete all products for a company, but would like to know what is the best practice for mass deletions in my use case.
I am thinking of having an endpoint
DELETE /products/{uniqueCpyCode}
I.e. delete products where cpyCode = request id. But i want to know is that best practice to mass delete resources like that or do i need an endpoint where i need to pass all ids although the number of products can potentially be close to a 1000 products.
Or is it better to only have the one delete endpoint and let the user call it multiple times.
Then another question i have, what if you want to delete the whole company. What is in general the better approach? 1) Call both Delete enspoints.
DELETE /products
DELETE /company
2) the user only call
DELETE /company
Which internally also call the DELETE /products enpoint.

So I am using the Vuetify 2 VCalendar and I was wonder if it would be possible to exclude the events from show in previous and next months in the view, so this is what I am talking about:
[enter image description here][1]
Currently, I am viewing "March 2024", but I am seeing "April 2024" events as shown in the screenshot.
This is the vcalendar code call:
```Javascript
<v-calendar
ref="calendar"
v-model="focus"
:type="type"
:events="shifts"
event-color="#f1f3f4"
event-text-color="#333"
:event-margin-bottom="5"
:event-height="155"
:events-more="false"
:show-week="false"
@click:event="handleClickEvent"
@click:date="!isDateBeforeToday($event) && isLoggedIn ? prepareAndOpenShiftCreationDialog($event) : null"
@click:day="!isDateBeforeToday($event) && isLoggedIn ? prepareAndOpenShiftCreationDialog($event) : null"
@change="loadAndUpdateShifts"
>
<template v-slot:event="{ event }">
<calendar-day :event="event" :is-logged-in="isLoggedIn"></calendar-day>
</template>
</v-calendar>
```
I am not sure if there is an appropriate prop or anything, but I would love to know.

### Summary
There is a difference between `any` in type parameter and `any` in regular function parameter. Your case is the former one for generics. So you need to instantiate `T` first when assigning it to the concrete variables
Ref. https://stackoverflow.com/questions/71628061/difference-between-any-interface-as-constraint-vs-type-of-argument
### In detail
It's because in `GetAllProducts`, type `T` is not decided yet. So it is impossible to assign `[]models.Products` to `T`.
```golang
func (db *DbConnection[T]) GetAllProducts() {
var re []models.Products
re, _ = db.GetAll()
}
```
But you can assign `models.Products` to `T` if `T` is decided as `models.Products`, like this.
```golang
db := DbConnection[models.Products]{}
var re []models.Products
re, _ = db.GetAll()
```
I reproduce your problem in the simplified version(https://go.dev/play/p/GHkDThFLOKG). You can find the same error `GetAllProducts()` but in the main code, it works. |
I used a combination of `REDUCE` and `SEQUENCE` to iterate through each date column.

headers;HSTACK("";dateRow);
date;dateRow;
res;INDEX(data;;1);
comp;INDEX(data;;2);
q;INDEX(data;;3);
lab;UNIQUE(res);
cost;q*fxCompCost(comp;date);
reducer;REDUCE("";SEQUENCE(COLUMNS(date));LAMBDA(acc;curr;HSTACK(acc;MAP(lab;LAMBDA(a; SUMPRODUCT((res=a)*CHOOSECOLS(cost;curr)))))));
result;VSTACK(headers;HSTACK(lab;DROP(reducer;;1)));
result
)
Names added to the worksheet:
ParamStartDate: `Q2`
ParamEndDate: `Q3`

I am plotting some lines with Seaborn:
```python
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
# dfs: dict[str, DataFrame]
fig, ax = plt.subplots()
for label, df in dfs.items():
sns.lineplot(
data=df,
x="Time step",
y="Loss",
errorbar="sd",
label=label,
ax=ax,
)
ax.set(xscale='log', yscale='log')
```
The result looks like [this](https://i.stack.imgur.com/FanHR.png).
Note the clipped negative values in the `effector_final_velocity` curve, since the standard deviation of the loss between runs is larger than its mean, in this case.
However, if `ax.set(xscale='log', yscale='log')` is called *before* the looped calls to `sns.lineplot`, the result looks like [this](https://i.stack.imgur.com/JVGG4.png).
I'm not sure where the unclipped values are arising.
Looking at the source of `seaborn.relational`: at the end of `lineplot`, the `plot` method of a `_LinePlotter` instance is called. It plots the error bands by passing the already-computed standard deviation bounds to `ax.fill_between`.
Inspecting the values of these bounds right before they are passed to `ax.fill_between`, the negative values (which would be clipped) are still present. Thus I had assumed that the "unclipping" behaviour must be something matplotlib is doing during the call to `ax.fill_between`, since `_LinePlotter.plot` appears to do no other relevant post-transformations of any data before it returns, and `lineplot` returns immediately.
However, consider a small example that calls `fill_between` where some of the lower bounds are negative:
```python
import numpy as np
fig, ax = plt.subplots(1, 1, figsize=(5, 5))
np.random.seed(5678)
ax.fill_between(
np.arange(10),
np.random.random((10,)) - 0.2,
np.random.random((10,)) + 0.75,
)
ax.hlines(0, 0, 10, color='black', linestyle='--')
ax.set_yscale('log')
```
Then it makes no difference if `ax.set_yscale('log')` is called before `ax.fill_between`; in both cases the result is [this](https://i.stack.imgur.com/ctRUi.png).
I've spent some time searching for answers about this in the Seaborn and matplotlib documentation, and looked for answers on SA and elsewhere, but I haven't found any information about what is going on here.

Given the following C program (MSVC does not optimize away the "work" for me, for other compilers you may need to add an `asm` statement):
```c
#include <inttypes.h>
#include <stdlib.h>
#define SIZE 10000
typedef struct {
int32_t a, b, c;
} Struct;
void do_work(Struct* data) {
int32_t* a = malloc(sizeof(int32_t) * SIZE),
* b = malloc(sizeof(int32_t) * SIZE),
* c = malloc(sizeof(int32_t) * SIZE);
int32_t* a_ptr = a, * b_ptr = b, * c_ptr = c;
for (size_t i = 0; i < SIZE; i++, a_ptr++, b_ptr++, c_ptr++, data++) {
*a_ptr = data->a;
*b_ptr = data->b;
*c_ptr = data->c;
}
free(a);
free(b);
free(c);
}
int main() {
Struct* data = malloc(sizeof(Struct) * SIZE);
for (size_t i = 0; i < SIZE; i++) {
data[i].a = i;
data[i].b = i;
data[i].c = i;
}
for (int i = 0; i < 500000; i++) {
do_work(data);
}
free(data);
}
```
(I have a similar program in Rust with the same conclusions).
Intel VTune reports that this program is 63.1% memory bound, and 52.4% store bound, with store latency of 26%. It recommends to search for false sharing, but I fail to see how there could be false sharing here. There is no concurrency, all data is owned by one core, the access patterns should be easily predicted and prefetched. I don't see why the CPU needs to stall on the stores here.
I thought that maybe the low and high bits of the addresses of the three allocations are the same and that causes them to be mapped to the same cache lines, but I remember reading that modern CPUs don't just drop some bits to assign a cache line but do more complex calculations.
Another thought was that maybe after the allocations are freed the CPU is still busy flushing the stores, and in the next run they are assigned the same address (or a close one) by the allocator and that brings problems for the CPU as it has to wait before storing new data. So I tried to not free the allocations, but that caused the code to be much slower.

In your case the find command is replaced with `"./? ./*"`. So the loop iterates only once with `f="./? ./?"`. In `echo "$f"` `$f` is expanded (parameter expansion) and replaced with the value of variable `f`. Because of the double quotes the result is considered as a word and printed without further expansion. And you see `./? ./*`.
In `echo $f`, `$f` is also expanded and replaced with the value of `f` but the expansion continues with the pathname expansion (there are several other expansions between parameter expansion and pathname expansion but they have no effect here).
Pathname expansion replaces `./?` with all files in current directory with single character names (in your case `./?` and `./*`) and `./*` is replaced with all files in current directory (in your case `./?` and `./*`). So, finally what is echoed is `./? ./* ./? ./*`. |
