Instances | A process wrapper for asyncronous use , using Tasks or Events | Job Scheduling library

I am trying to compile and load dynamically generated Java code during runtime. Since both ClassLoader::defineClass and Unsafe::defineAnonymousClass have serious drawbacks in this scenario, I tried using hidden classes via Lookup::defineHiddenClass instead. This works fine for all classes that I tried to load, except for those that call lambda expressions or contain anonymous classes.

Calling a lambda expression throws the following exception:

I've noticed that when using VS Code with the current version of Haskell (GHC 9.2.1 and HLS 1.6.1.0), I no longer receive errors when I write type signatures in my instance declarations, even though I haven't included the {-# LANGUAGE InstanceSigs -#} extension.

Was there a change made to Haskell recently to allow instance signatures by default?

Haskell hobbyist here - is it possible to map a polymorphic constant over a list of types in a generic way?

More precisely, consider this snippet:

We have deployed a django server (nginx/gunicorn/django) but to scale the server there are multiple instances of same django application running.

Here is the diagram (architecture):

Each blue rectangle is a Virtual Machine.

HAProxy sends all request to example.com/admin to Server 3.other requests are divided between Server 1 and Server 2.(load balance).

Old Problem:

Each machine has a media folder and when admin Uploads something the uploaded media is only on Server 3. (normal users can't upload anything)

We solved this by sending all requests to example.com/media/* to Server 3 and nginx from Server3 serves all static files and media.

Problem right now

We are also using sorl-thumbnail.

When a requests comes for example.com/,sorl-thumbnail tries to access the media file but it doesn't exist on this machine because it's on Server3.

So now all requests to that machine(server 1 or 2) get 404 for that media file.

One solution that comes to mind is to make a shared partition between all 3 machines and use it as media. Another solution is to sync all media folders after each upload but this solution has problem and that is we have almost 2000 requests per second and sometimes sync might not be fast enough and sorl-thumbnail creates the database record of empty file and 404 happens.

Thanks in advance and sorry for long question.

I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).

Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.

I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.

As far I was trying for example changing all places with hasher->check part like here:

I started with this type for leaf-valued trees with labeled nodes:

I have to do some initial setup each time the app starts, but I'm getting the error:

The error is clear, the answer is not. I tried putting the init in a subview, but I can't, it needs to be in the root @main. This is how I have it defined:

Please consider a simple Django app containing a central model called Project. Other resources of this app are always tied to a specific Project.

Exemplary code:

I'm using io.github.resilience4j. Everything is working fine with 1.6.1 version but when upgraded to 1.7.1 version my application is not running. Please find my code changes below.
