In Laravel 11, I want to add a custom attribute named age in a Citizen model. It should calculate the age of a citizen from the birthdate. public function getAgeAttribute() { return $this->birthdate->diffInYears(\Carbon\Carbon::now()); } I have tried the code above but it does not work, Any ideas?

Afternoon, I'm trying to plot some objects on top of an image in Vispy, but somehow, they always get plotted behind it. For what i've read, the order in which everything is added in vispy should determine the layer position, but it seems my image always gets on top of everything. First i add the image to the canvas with: Image = scene.visuals.create_visual_node(visuals.ImageVisual) I = Image(parent=sc, interpolation="nearest",method='subdivide') I.set_data(img) Where img is the image path and sc is the canvas view, then, any object added, for ex, a line: Line = scene.visuals.create_visual_node(visuals.LineVisual) L = Line(parent=sc) L.set_data(line, color=color,width=width, connect=connect) And it gets plotted behind the image Is there anyway, any arg or similar, to set an object to be placed in front of the previous ones, or to keep the image always on "backgr

I am implementing a self hosted feed generator for bluesky. I ran the script to register it with no errors, but when I go it in bsky.com, I get the following: Hmm, the feed server appears to be misconfigured. Please let the feed owner know about this issue. Message from server: invalid feed generator service details in did document: did:web:usa-congress-wind-34f9235d0865.herokuapp.com My /xrpc/app.bsky.feed.describeFeedGenerator URI returns the following: { "did":"did:web:usa-congress-wind-34f9235d0865.herokuapp.com", "feeds":[ { "uri":"at://did:web:https:usa-congress-wind-34f9235d0865.herokuapp.com/xrpc/app.bsky.feed.getFeedSkeleton" }]} My /xrpc/app.bsky.feed.getFeedSkeleton URI does return data. { "cursor":"feed:535,t:2026-02-06T00:37:38.307000Z,post:25803105", "posts":[ "at

I am looking for a WebDAV server on Linux that takes user permissions into account, meaning that users should log in with their credentials (Linux username and password) and that they should only be able to read and write file they have access to (via Linux permissions or ACLs), like IIS does on Windows. From what I understand the only way to enforce filesystem permissions correctly (access, ownership, etc) is to have the web server process run as the logged in user. My best bet was to use Apache httpd, with WebDAV enabled, Basic Auth, with PAM for authentication, and the mod-ruid2 module that can dynamically switch the user of the httpd process to the user returned by PAM. But it turns out that mod-ruid2 is no longer maintained and that no replacement exists. What other options exist?

From a performance perspective, does it make sense to create a new dslContext per HTTP/API request? I need to set some request specific session variables (like user_id), for dslContext but I'm worried doing this will put too much pressure on the DB or Connection pool.

I have a web application (SPA) that accesses SharePoint Online files on behalf of a logged-in user (Delegated permissions). The application does not use a Service Principal for file access; it relies entirely on the user's context. The User: An external Guest user (B2B) invited to the tenant. The Action: The user logs in, and the app attempts to resolve a specific SharePoint sharing link (sent via "Specific People" sharing) using the Microsoft Graph API. The Issue: The API call returns 401 Unauthorized (Code: accessDenied) in the Production tenant. The Mystery: The exact same code, configuration, and user setup works perfectly in my Lab tenant. When opening the link directly - not through my web app, it works! I first have to confirm my email, click on 'Next', but then all is good,

I have a simple code thet works fine: // app.js app.get("/welcome", userController.welcome); // controller.js exports.welcome = (req, res) => { res.json({ "users": 'users' }); } However i need to use DB-requests in the controller. So i rewrote my code like this: // app.js app.get("/welcome", userController.welcome); // controller.js exports.welcome = async (req, res) => { try { const users = await User.find({}); res.json({ "users": users }); } catch(error) { res.status(404).send(); } } After this my code stopped working. This is reflected in the fact that the browser always started showing an 404error. Please help my get users list in the browser instead of 404error.

I am using Flink with java where I am facing a type erasure problem. I have an interface called TransformationService, which has multiple implementations, only one of which is used by a single flink job. This is decided at runtime as shown in the code below. Following is the signature of my Transformation Service - public interface TransformationService<EVENT extends Event, KEY extends Key> { KEY keyBy(EVENT ev); } This is how it is being used in the calling code of the pipeline - TransformationService<Event, Key> service = getImplementation(pipelineType); DataStreamSource<Event> source = ...; source .uid("source") .rebalance() ... ... .keyBy(service::keyBy) ... ... env.execute(job); Each implementation of TransformationService uses concrete key and event types that extend Key and Event classes, respectively. An example implementation of Transf
