cross-posted from: https://lemm.ee/post/46067136

I'm designing a webapp that is supposed to be an AR environment on your phone, to be viewed with something like Google Cardboard, but I am having an issue that the segmentPointer object that is meant to appear when clicking on an object is not.

I've checked the geometry displays correctly in a sandbox, and when I change it to a 3d object rather than shapeGeometry it does display, but I cannot figure out why it is not displaying how I want it to.

The project is at https://voxelverse.jackgreenearth.org, and the code is quite long, but it is here to read in its totality below as it might need the whole context to discover the error. I've tried myself looking through the code, and I've tried searching the web and asking LLMs, but I couldn't figure it out, so please help me, fellow humans.

I followed the recommended processes for adding images to my app, and it is being displayed correctly on the layout preview, but not at all on the app. I have vector assets, webp, png images, but none are being displayed.

The project is too big to put here in its entirety, but please ask for any snippets that could help you solve the issue. I've tried searching the web and asking LLMs and neither could help, so please help me, fellow humans.

We are thrilled to announce the release of Qt 6.8, packed with support for new desktop, mobile, and embedded platforms, hundreds of improvements, and exciting new features to boost your development experience and meet the needs of demanding applications.

For this release we have focused on improving and stabilizing existing functionality. With over 500 bug fixes and performance improvements since Qt 6.7, your existing code will run better without changing a single line. On macOS, Qt Quick applications now integrate with the native menu bar, and for a native Windows 11 look they can use the new Fluent style. Resizing Quick windows is snappier on macOS with Qt 6.8, and on Windows the application start-up time has been improved by changing the default font database to DirectWrite.

Several modules that were under technology preview have been completed: Qt Graphs, Qt HttpServer, and Qt GRPC are promoted to be fully supported from this release on. Thanks to the feedback from our users we were able to finish those modules with substantial improvements since their initial introduction as technology previews.

Hi ! I've been working on this article for the past few days. It would mean a lot to me if you could provide some feedback.

It is about implementing a physico-chemical simulation as my first attempt to write a shader. The code is surprisingly simple and short (less than 100 lines). The "Prerequisite" and "Update rules" sections, however, may need some adjustments to make them clearer.

Thanks for reading

Hello my fellow, lemons? I have this problem in my current project I’m out of clue how to approach it. Maybe someone had similar experience and can give an advice.

Our requirements captured in JIRA. Throughout years we accumulated thousands of user stories. Say suppose following naive requirements team knows about:

  • Day 1: create home page
  • Day 20: create profile page
  • Day 50: add green footer to all pages
  • Day 100: create admin page Day 150: change footer color to blue

Now I’m doing refactoring (yes, I know, this is the actual problem) on day 400 and noticed that footer on profile page having green footer. Because requirements are just set of individual statements not consolidated with all history of system no one on the team knows why is that, is it bug or requirement did change on day 300 but we cant find it now.

When I worked in Waterfall we had BRD and FRD stating current actual desired state of system which was “reduced” from individual requirements which were coming in throughout project life. When in doubt devs can check FRD and not only know how system expected to behave but also which are other parts of the system that will be affected. How is it in Agile? To my understanding FRD is not a thing in Agile. Do I need to scan through hundreds of tickets and hope I didn’t miss anything every time i’m doing any non-trivial change to system?

Considering how SO is killing itself rather quickly, it would be interesting to have a platform with similar structure but taking users interests instead of profit of executives. I am not saying their system is perfect, I have made a post in the past on their meta community regarding how hard it is for new contributors to start. I remember hearing about an alternative but after searching for it, I couldn't find anything.

Does anyone know such platform?

Edit: After I posted I came across Codidact. I will try using it! Feel free to post other alternatives though!

Does anyone know, or can anyone guess, the business case for predictive text? On phone apps, it is often incredibly difficult to turn off. Why is that, do you think? (The examples I have recent experience with are Facebook and Outlook mobile apps.)

I would have thought that, for AI training purposes, they would want humans typing things and not just regurgitating canned responses. But apparently not?

I need to help auditing a project from another team.
I got the pointers on what's expected to be checked, but I don't have like templates for documents for what's expected from an audit report which also means I'm not sure what's the usual process to conduct an internal audit.
I mean I might as well read the whole repo, but maybe that's too much?

Any help or pointers on what I need to investigate to get started would be great!

Hello everyone, I have an idea to make a map with fog of war, when you walk you explore new areas and points of interest but you can't see unexplored areas. I'm not sure if it's a good idea, what is your opinion?

One thing that pretty consistently drops me out of the flow state is having to dig through documentation for whatever I'm trying to use, or even worse having to dig through its source code because the documentation is either nonexistent or eg. plain wrong
