I am developing an Employee Management System in Blazor Server using PostgreSQL for the database and JWT for authentication. I am using Microsoft Identity tables for user data. I have created a login page that accepts an email and password, and I can authenticate the user and generate a token. The problem occurs when I am trying to store the token in protected local storage so I can reuse it to attach it to the API header as a bearer token. My current architecture is below.

I created a microbit serial communication project for my college's Intro to Computer Science course. My external Python script can receive data from the microbit, but the microbit cannot read from the script. My computer is a Windows 11 Lenovo Yoga. laptop. Below is the Python code from my external as provided in the assignment, with the lines beginning at the msgStr variable being my only addition. I already imported the PySerial library using the pip install command before building the project. import serial import serial.tools.list_ports as list_ports PID_MICROBIT = 516 VID_MICROBIT = 3368 TIMEOUT = 0.1 def find_comport(pid, vid, baud): ''' return a serial port ''' ser_port = serial.Serial(timeout=TIMEOUT) ser_port.baudrate = baud ports = list(list_ports.comports()) print('scanning ports') for p in ports: print('port: {}'.format(p)) try: print('pid: {} vid: {}'.format(p.pid, p.vid)) except Attribu

Stripe Connect Express Onboarding — "User Not Found" error on Android only (React Native Expo) Problem I'm implementing Stripe Connect Express account onboarding in a React Native Expo app. The flow works perfectly on desktop browsers and iOS, but consistently fails on Android devices with a "User Not Found" error. Steps to Reproduce User taps the "Connect to Stripe" button in the app Backend generates and returns a Stripe Connect Express onboarding URL URL opens in either an Android external browser or a WebView Stripe onboarding page loads and prompts for a phone number I enter the Stripe-provided test phone number (test mode) After submitting, the error "User Not Found" is displayed What I've Tried

I am currently evaluating the performance impact of implementing Power BI Deployment Pipelines within our organization. We are operating on a A2 capacity and I want to ensure that our CI/CD process doesn't lead to unexpected throttling or "Carryforward" issues. Specifically, I am looking for insights or documentation regarding: Memory Footprint: Since each stage (Dev, Test, Prod) creates a unique workspace, does the capacity treat these as three distinct resident models in memory? If we have a 2GB dataset, should we plan for a 6GB overhead across the pipeline? CPU (CU) Spikes during Deployment: What is the typical "Compute" cost of the deployment operation itself? I am concerned about background credit consumption when moving large metadata models from Test to Production during peak hours. Post-Deployment Refresh Impact: Ho

I'm having a bad experience running Android Emulator (both Cuttlefish and Goldfish) on my Linux Ubuntu 22.04 - AMD Ryzen 9. First of all, I am trying to execute the basic tutorial of https://source.android.com/docs/setup/build/building , and after the compilation steps, the emulator open, stays on for a short period and randomly restarts my computer. ~/aosp$ emulator -accel-check accel: 0 KVM (version 12) is installed and usable. accel Setup: CPU: AMD Ryzen 9 | MB: AORUS B650 GPU: NVIDIA GeForce RTX 4060 - Driver Version: 580.119.02 OS: Ubuntu 22.04 KVM: working SVM Mode: enabled in BIOS AOSP: android-14.0.0_r1 CPU cores: 24 RAM 32GB + SWAP 36GB I’ve tried multiple tutorials and r

I am experimenting with a Python-based MCP server to connect AI assistant with Aspen Plus. The idea is that the AI assistant can interpret user instructions and trigger simulation-related tasks through Claude code. For example, the AI could help: Analyze simulation workflows Suggest parameter settings Trigger simulation runs Interpret results My current approach is to use Python as the middle between Claude Code and Aspen Plus. The Python layer would translate AI's instructions into commands that interact with Aspen Plus. I am wondering what architecture is commonly used for this type of system. Is it better to build a modular tool interface that the AI can call (for example, functions like run_simulation() or modify_parameters()), or should the AI interact directly with the Aspen Plus API? Any suggestions or best practices for integrating AI assistants w

I have a div that is fixed and contains an img inside to display images, but it shows images that are different sizes, and that means it goes off screen when it tries to display vertical images how do I make it so it sizes down (in both horizontal and vertical size so the image is not stretched) when it goes outside the bounds of the window ? I tried using height but then other parts like the text and exit button become misaligned with the image here is the relevant parts of code: HTML <div class="showcase"> <button onclick="closeshowcase()">X</button> <img id="showcaseimg" src="images/photography/image0.webp"> <p>this is an image</p> </div> CSS .showcase{ pointer-events: none; opacity: 0; scale: 90%; position: fixed; width: 85%; z-index: 5; top: 50%; lef

I have recently taken a break from regular C++ (hobby) programming in order to try implementing some basic destructor functionality in C (in a way which appears more elegant than simply writing the destructor at the end of the function). I have tried attempting to implement the "defer" keyword found in GO, using C macros. However, this appears more difficult than initially seems, due to being unable to concatenate an identifier with a number generated by a constant and then create a label. This may be impossible due to the way the clang compiler processes code. Here are my main.c main file: #include <stdio.h> #include <stdlib.h> #include "defer.h" int main(void) { #define DEFER_ID __COUNTER__ DF_BEGIN(int, 0); void *text = malloc(256); if (text == NULL) { DF_RETURN(1); } DF(free(text); printf("Text Freed!\n")); printf("Put regular code he

When developing software for BYD's in-vehicle infotainment system, the app lacks a system signature, and the system is not rooted. How can I obtain information from the system? package com.findCar.app import android.hardware.bydauto.speed.BYDAutoSpeedDevice import io.flutter.embedding.android.FlutterActivity import io.flutter.plugin.common.MethodChannel class MainActivity: FlutterActivity() { private val CHANNEL = "byd_auto" override fun configureFlutterEngine(flutterEngine: io.flutter.embedding.engine.FlutterEngine) { super.configureFlutterEngine(flutterEngine) MethodChannel( flutterEngine.dartExecutor.binaryMessenger, CHANNEL ).setMethodCallHandler { call, result -> if (call.method == "getSpeed") { val device = BYDAutoSpeedDevice.getInstance(this) val speed = device.currentSpeed result.success(speed) } else { result.notImplemented() }
