Quick tip about model serialization in event constructor

I had an issue with relations being resolved during unserialization, but because there is a polymorphic relation sometimes it can try to resolve a nested relation that does not exist anymore. Use the #[WithoutRelations] attribute to fix it. submitted by /u/imwearingyourpants

How to find ceritain value in multiple section and return other value

How should I write this formula


Find the Square section where Value A at (Gary is in 8 in this case), and get the name " Ocho" from list underneath


then find where is Value B, Put Ocho at highlight place in value B section


Then list the rest clockwise


Sample Image:



I tried to put value clockwise by using
=INDEX(D22:D29,,XMATCH(D22:D29,MOD(SEQUENCE(8,,E29-1),8)+1))

OpenCV - How to compute 3D points with SfM methods with known fundamental matrix

For a university project, we are working on implementing a basic SfM pipeline, using Middlebury's "temple" dataset. This means that, for each image, the projection matrix for that given image is known. I have done some reading and seen some examples on SfM reconstruction, where, usually, the camera rotation and translation are unknown and PnP algorithms are used to obtain them.
My question is, given we know the projection matrix for any given image, what would the processing pipeline look like? I envision something along the lines of:



* Compute SIFT keypoints and descriptors for each image.

* Pair "adjacent" images (in this case, images with sequential ids from the dataset)

* Find point matches for each pair using KNN or similar matching algorithm.

* Use cv2.triangulatePoints to find the corresponding 3D point for each of the 2d point matches using the known projection matrices.






I understand that, generally, the most difficult aspect of SfM is precisely the step we are skipping over of pose estimation. However, for now we are only aiming for a basic implementation, possibly implementing a "complete" algorithm that includes this step later.


Still, I am unsure as to whether there are any processing steps that would be necessary in order to obtain "good" results.



* Would something like undistortPoints be necessary for this estimation?

* What would be the most efficient way of building the point cloud (for example, building feature tracks and only include points that result from the triangulation of some number of images n)?

* Finally, where and how should we discard pair outliers? Most of the functions offered by OpenCV use RANSAC as part of the pose estimation process, and I don't know if there are functions that would allow us to use the algorithm in our case (if it would even be necessary).






So far, we have implemented a basic SIFT keypoint extractor.
Unsure where to continue from here.

How to resolve a Cors error when trying to get an authentication token using authorisation code grant in Next.js

I have an app where im trying to send a generated pdf to get a signature. Pretty straightforward.
I got the authentication working in postman, but when I try it in code, I get this error:


Access to fetch at '
https://account-d.docusign.com/oauth/token' from origin '
http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.


I can retrieve the oauth code with this:
if (router.asPath !== router.route) {
setOAuthCode(new URLSearchParams(window.location.search).get("code"));
}



but in a seperate use effect, i try to submit this oAuth code, it falls appart:
useEffect(() => {
const getAuthToken = async () => {

const tokenUrl = "
https://account-d.docusign.com/oauth/token"; /> const encodedSecret = btoa(
`${process.env.NEXT_PUBLIC_DOCUSIGN_INTEGRATION_KEY}:${process.env.NEXT_PUBLIC_DOCUSIGN_CLIENT_SECRET}`
);

const headers = {
"Authorization": `Basic ${encodedSecret}`,
"Content-Type": "application/x-www-form-urlencoded",
};
const body = new URLSearchParams({
grant_type: "authorization_code",
code: oAuthCode,
});

const response = await fetch(tokenUrl, {
method: "POST",
headers: headers,
body: body,
});

if (!response.ok) {
throw new Error(
`Failed to get access token: ${response.status} ${response.statusText}`
);
}
const data = await response.json();
setAuthToken(data.access_token);
};
getAuthToken();
}, [oAuthCode]);



Any kung fu would be greatfully accepted

.Net 8 XUnit: Use an In-Memory DBConnection for testing as a replacement for the real MySqlConnection

I'm creating tests for my .Net 8 API, and as I want to test with fake self created data (instead of using the real MySql connection) I'm having problems figuring out how to implement that behavior, I mean, using -for example- an In-Memory database.


We use CQRS (Mediator pattern) for the database queries, and on each query handler we inject ICloudStackCoreConnectionFactory which includes (among others) a CreateConnection method that returns a DBConnection (in our case, a MySqlConnection):


ICloudStackCoreConnectionFactory:
public DbConnection CreateConnection(Region region)
{
return (DbConnection)new MySqlConnection(GetConnString(region));
}



I'd like to replace that MySqlConnection implementation by an in-memory connection so I can test with a reduced set of fake data, but I don't know how to do it.


We use a "Lab" to create all stuff needed for the tests, and the Lab includes a create method as follows:
public static Lab Create(ITestOutputHelper output)
{
var appFactory = Vdc.Libs.AspNet.Testing.Setup.Factory(
out var client,
out var authorize,
out var identity,
out var faker,
role: $"{VdcSecurity.Role.Management},{VdcSecurity.Role.ManagementAdmin}",
output: output,
setup: services =>
{
}
);
return new Lab(identity, appFactory, client, authorize, faker);
}



I know I could use Mock library to mock the ICloudStackCoreConnectionFactory interface, but as I debug, when the test starts the real "Program.cs" is launched, so is clear we are using the real hosted services and so I don't know how to replace only that interface with the mocked one.


Then I also don't know how to return a DBConnection In-Memory database with data in the "CreateConnection" method.


Any help?

Pass multiple arguments to single command in custom position xargs

I want execute a command where I have the args as single string but they need to be in a custom position. E.g. in the following example I want the args to be positioned before any fixed args that I have written after the cp comamnd i.e. the path argument /somedir


I want:
echo -n 'file1 file2 file3' | xargs -d ' ' -I{} cp {} /somedir



to behave like:
cp file1 file2 file3 /somedir



but it doesn't...


It also looks like when including the -I{} option, the -d option makes xargs behave differently. It seems like it tries to pass each argument to a separate command call rather than all of them toa single one.


For example, this works:
echo -n 'file1 file2' | xargs -d' ' diff



But this fails
echo -n 'file1 file2' | xargs -d' ' -I{} diff {}



With error:
diff: missing operand after 'file1'
diff: Try 'diff --help' for more information.
diff: missing operand after 'file2'
diff: Try 'diff --help' for more information.



How can I get echo -n 'file1 file2 file3' | xargs -d ' ' -I{} cp {} /somedir to behave as intended

Image not loading in HTML page when trying to change using GetElementByID method

I am attempting to write an simple function in an HTML page which displays the image and there are few buttons which change the image I have used the "document.getElementById('myImage').src= " command to change it but there is no image shows after I click the image. The same image is loading properly using the tag. The same button works if I use a link direct taken from google. Below I have pasted the code. Any suggestions are appreciated.





This page shows changing emotions using various buttons
