Different maps and topographical maps [closed]

18 June 2026 @ 6:26 am

The Google Maps API should render the same surrounding roads as the official maps.google.com for the same coordinate and zoom level. Is this a data sync delay between the official site and the public API? Or is there any missing config I need to add to display these local roads?

How to register a blurry IR image to a sharp RGB image when the scene has a repetitive grid structure?

18 June 2026 @ 6:19 am

I am a student working on a plant phenotyping project. I am trying to align RGB and infrared (IR) images of plant trays. The setup: RGB camera: sharp, 4112×3006 IR camera: blurry, 1024×768 (upscaled to match RGB) The scene is a 4×4 grid of plant pots — very repetitive and symmetric IR Image What I have tried: Manual homography — picked matching points by hand, not accurate enough RIFT (Radiation-invariant Feature Transform) — designed for multimodal images, but the repetitive grid causes too many wrong matches. RANSAC only keeps 3–5 inliers RIFT on a single cropped pot — used manual homography as rough alignment, then ran RIFT on one pot crop to avoid the repetitive grid problem. Th

Microprocessor Lab Project Ideas for Smart Healthcare Device / Assistive Healthcare Technology

18 June 2026 @ 5:30 am

I'm looking for ideas for a university microprocessor lab project. The project should involve a microcontroller (such as Arduino, ESP32, STM32, or PIC) and focus on Smart Healthcare Devices or Assistive Healthcare Technology.

WinUI3 crash on startup after upgrading to modules

18 June 2026 @ 4:48 am

This only happens when launched with the debugger attached. The program behaves as expected if the debugger is attached after the window opens. I believe I've encountered similar problems before i.e. a trace before with IApplicationStatics (but never bothered to understand it), so I was hoping someone would recognise it.

The same dumb question... C++ or Rust. Ik, Ik just read this please

18 June 2026 @ 3:46 am

I am currently learning physics, math, and embedded systems programming while trying to sharpen my overall software development skills. To combine all these subjects into a fun, hands-on project, I am building a physics simulation. The goal is to create an environment where I can simulate a robot, using an ESP32 as its physical 'brain.' However, returning to my main question: I want to take the 'happier,' less frustrating path to learn all of this. I am using Raylib for the simulation and Espressif’s ecosystem for the hardware. Since I want to avoid getting stuck just trying to make the tooling work, I need the best possible ecosystem compatibility. To simplify: Is it better to stick with C++, or should I switch to Rust for a smoother, more enjoyable learning experience?

Issue: Next.js + Better Auth Successful Login (200 OK) but Server Component redirecting back to /sign-in (Redirect Loop behind Nginx)

18 June 2026 @ 3:46 am

We are running a Next.js App Router application (standalone build) using Better Auth and Prisma inside a Docker container behind an Nginx reverse proxy. When attempting to log in: The credentials verification is successful. The login endpoint (/api/auth/sign-in/username) returns 200 OK with the session and user JSON. The browser successfully receives and stores the secure cookie __Secure-better-auth.session_token (mapped to the correct domain, Path=/, Secure, HttpOnly, SameSite=Lax). The database (Session table) successfully creates the session record. Client-side requests to /api/auth/get-session return 200 OK with the session payload (showing the user session is active). The Bug: When the page redirects to /

How to count the frequency of items in a Python list and store them in a dictionary? [duplicate]

18 June 2026 @ 3:02 am

I have a Python list containing multiple food orders, where some items appear multiple times. I want to count how many times each item appears and store the results in a dictionary (where the food name is the key and the count is the value). Here is my current approach using a for loop: orders = ["Burger", "Pizza", "Burger", "Ramen", "Pizza", "Burger"] count_dict = {} for item in orders: # This throws a KeyError because the key doesn't exist yet count_dict[item] += 1 print(count_dict) When I run this, I get a KeyError. I understand it is because the key does not exist in the dictionary when I try to add 1 to it for the first time. What is the best or most Pythonic way to handle this? Should I check if the key exists using an if statement, or is there a built-in tool in Python that can do this more efficiently?

Visual Studio Forms Designer UI Looks Like WIN7?

18 June 2026 @ 1:24 am

I'm using Win11 and Visual Studio 2022. When designing a windows desktop form in the IDE it shows windows UI elements from windows 7. When running my app it shows windows 11 UI elements and does not show the window at the same resolution as in the IDE. Anyone know why this is? How it looks when runningRunning App How it looks in the IDEIDE Form Designer I'm not looking to have it in the WIN7 looking UI. I'm more interested in why VS still shows WIN7 and why the difference in resolution / sizing. I did have to re-arrange some of the elements to keep them from being cut off in the running app.

Online Banking Login Embed code for website

17 June 2026 @ 6:33 pm

I am looking to get the online banking login embed code so that a customer can embed it on the website we are building. How do we go about getting that code? We were directed to jackhenry.dev but that seems more like API integration rather than form embed or html. An example of what we are trying to do is like US Bank OLB Example

Modelica unit for trace substance in PPM

17 June 2026 @ 12:38 pm

I want to use a variable or parameter in Modelica to track or specify trace substances in parts per million (PPM). Can I use one of the existing types from Modelica.Units.SI ?I would think the unit is something like mol per million mol, can that be specified as unit or display unit? It might be similar to percent or permille.
