How to manage data and perform CRUD operations on a "models" that are stored in YAML files rather than in my database?

I'm building an LMS and want to add a feature where tutors can create quizzes and students can attempt those quizzes. I want the quizzes to be stored as YAML files rather than in my database (I'm using MySQL). The main two reasons being so that they can be easily version controlled and faster to retrieve. Stack: - Breeze scaffolding (Vue & Inertia SSR) - Filament admin panel My question is, since I don't have a quizzes table, is there still some way I can make a Quiz model? Because it seems to me that I would instead have to make a Quiz class that doesn't extend Model and parses a given YAML file. Surely there must be some packages out there that allow you to work with models and Eloquent for data stored in flat-files. Another approach I could try is installing Statamic into my project but seems a bit overkill to have both Filament and Statamic on the same project for what is essentially a single Statamic collection (Quizzes). A Quiz entry might look something like this: title: "Algebra Quiz" author: 3 level: "Intermediate" subject: 2 topics: - Algebra questions: - question: "What is the equation of the line that passes through the points (2, 3) and (-1, 5)?" choices: - "y = 2x + 7" - "y = -2x + 7" - "y = 2x - 7" - "y = -2x - 7" answer: "y = -2x + 7" - question: "What is the value of x in the equation 3x - 7 = 14?" choices: - "7" - "9" - "11" - "15" answer: "7" - question: "What is the solution set for the equation 2x + 5 = 9?" choices: - "{2}" - "{2.5}" - "{3}" - "{3.5}" answer: "{2}" Regarding author and subject fields, I'm not sure whether to store these as IDs as I did above, or with some UUID such as email for author and slug for subject. submitted by /u/lewz3000 [link] [comments]

                    $i++;

                }

SpinLock VB.Net Example From MSDN Possibly Produces Incorrect Behaviour

The code below is part of an example from MSDN. It is the example on how to use SpinLock but to my eye there is a race condition in it. Why I think this is because of the Dim lockTaken As Boolean = False line in the UpdateWithSpinLock method. It appears to me that the following could occur: Thread 1 enters UpdateWithSpinLock method and executes as far as _queue.Enqueue(d) and a context switch occurs. Thread 1 now has the SpinLock and lockTaken is True. Thread 2 enters and only executes as far as the line Dim lockTaken As Boolean = False. Thread 2 has now set lockTaken back to False and a context switch occurs. Thread 1 continues and tests lockTaken in the Finally block and finds it to be False (it should be True for Thread 1) so doesn't release the SpinLock. Thread 1 exits the method leaving the lock inplace and thread 2 waiting forever. Imports System.Threading Imports System.Threading.Tasks Class SpinLockDemo2 Const N As Integer = 100000 Shared _queue = New Queue(Of Data)() Shared _lock = New Object() Shared _spinlock = New SpinLock() Class Data Public Name As String Public Number As Double End Class Shared Sub Main() UseSpinLock() Console.WriteLine("Press a key") Console.ReadKey() End Sub Private Shared Sub UpdateWithSpinLock(ByVal d As Data, ByVal i As Integer) Dim lockTaken As Boolean = False Try _spinlock.Enter(lockTaken) _queue.Enqueue(d) Finally If lockTaken Then _spinlock.Exit(False) End If End Try End Sub Private Shared Sub UseSpinLock() Dim sw = Stopwatch.StartNew() Parallel.Invoke( Sub() For i As Integer = 0 To N - 1 UpdateWithSpinLock(New Data() With {.Name = i.ToString(), .Number = i}, i) Next End Sub, Sub() For i As Integer = 0 To N - 1 UpdateWithSpinLock(New Data() With {.Name = i.ToString(), .Number = i}, i) Next End Sub ) sw.Stop() Console.WriteLine("elapsed ms with spinlock: {0}", sw.ElapsedMilliseconds) End Sub Shared Sub UpdateWithLock(ByVal d As Data, ByVal i As Integer) SyncLock (_lock) _queue.Enqueue(d) End SyncLock End Sub Private Shared Sub UseLock() Dim sw = Stopwatch.StartNew() Parallel.Invoke( Sub() For i As Integer = 0 To N - 1 UpdateWithLock(New Data() With {.Name = i.ToString(), .Number = i}, i) Next End Sub, Sub() For i As Integer = 0 To N - 1 UpdateWithLock(New Data() With {.Name = i.ToString(), .Number = i}, i) Next End Sub ) sw.Stop() Console.WriteLine("elapsed ms with lock: {0}", sw.ElapsedMilliseconds) End Sub End Class Is the way I'm interpreting this correct. If it's not could you please show me what I'm missing. Thanks in advance.

laracon US 2023 lodging

I'm stoked laracon US is back in person. One of my favorite parts of laracon in years past is how rad the community is, and I loved it when everyone was staying in the same hotels back in the KY years. It felt a bit fragmented in both Chicago and New York with everything all spread out, but it was still a blast. So yeah, where are people planning on staying in Nashville this July? submitted by /u/lapubell [link] [comments]

How to implement chat GPT in Laravel

1. Install the guzzlehttp/guzzle package using Composer:

   bash
   composer require guzzlehttp/guzzle
   

2. Create a new controller that will handle the chatbot logic:

   go
   php artisan make:controller ChatbotController
   

3. In the ChatbotController, import the GuzzleHttp\Client class:

   arduino
   use GuzzleHttp\Client;
   

4. Create a function that will handle the chatbot requests. In this function, you will make a POST request to the ChatGPT API endpoint and pass the user's message as a parameter:

   php
   public function chatbot(Request $request)
   {
       $client = new Client();
       $response = $client->post('https://api.openai.com/v1/engine/<ENGINE-ID>/completions', [
           'headers' => [
               'Authorization' => 'Bearer <API-KEY>',
               'Content-Type' => 'application/json',
           ],
           'json' => [
               'prompt' => $request->message,
               'max_tokens' => 50,
               'temperature' => 0.7,
           ],
       ]);
       $result = json_decode($response->getBody()->getContents(), true);
       return response()->json(['message' => $result['choices'][0]['text']]);
   }

5. In the routes/web.php file, create a new route that will point to the chatbot function in the ChatbotController:

   css
   Route::post('/chatbot', 'ChatbotController@chatbot');
   

6. Finally, in your front-end, create a form that will submit the user's message to the chatbot route using AJAX:

   php
   <form id="chat-form">
       <input type="text" name="message" placeholder="Type your message...">
       <button type="submit">Send</button>
   </form>
   <div id="chat-messages"></div>
   <script>
       $('#chat-form').submit(function(e) {
           e.preventDefault();
           $.ajax({
               type: 'POST',
               url: '/chatbot',
               data: $('#chat-form').serialize(),
               success: function(response) {
                   $('#chat-messages').append('<p>You: ' + $('#chat-form input[name=message]').val() + '</p>');
                   $('#chat-messages').append('<p>Chatbot: ' + response.message + '</p>');
                   $('#chat-form input[name=message]').val('');
               },
           });
       });
   </script>

That's it! With these steps, you should now be able to implement ChatGPT in Laravel
