#672Working on improving my barista skills, although my latte art seems to have ground (sorry) to a halt at 'heart', which I guess is level 1.
Next I'd like to add a Pi into the espresso machine for some remote fun. A couple of the control panel pcb-pop-style? buttons are failing, and I thought it might be fun to try and control via a touch screen. I suspect I'll want some kind of timer on the machine side to ensure a safe/timely cut-off, but I haven't done anything like that since using a 555 a very long time ago. Maybe I'll just drive a relay from a digital Pi i/o pin, but suspect it is switching mains level V.

#673I recently made a little tool for people interested in running local LLMs to figure out if their hardware is able to run an LLM in GPU memory. https://canirunthisllm.com/
Looks good.
Feature request - Have a leaderboard of LLM for x/y/z tasks or pull it from existing repo. Suggest the best model for given GPU for x/y/z task.
If there is better model which my GPU can run, why should I go for the lowest?

And maybe provide ollama/lm studio run command for given model/quantization

#675Earlier quoted context omitted.
Has anyone been hit by a car there ever? I think people used to use science to set speed limits.
They did, 30 km/h is a lot safer than higher speeds. You seem to imply someone has to be hit by a car before enforcing the speed limit, am I correct?
No, just implying that when someone is hit that the posted limit has more scrutiny.

#676A C-based graphics engine/raycasting engine to make 90's games like Wolfenstein3D (1992) - but on a never-before seen scale. The scale is RNG worlds like Minecraft. I've never seen that before with a Raycaster. Here is my progress so far (I've had a month break) https://github.com/con-dog/chunked-z-level-raycaster/blob/ma... Not for profit, just for fun and exploration
Wow, this is really cool. Do you take inspiration from or have you looked at the original Wolfenstein3D code? https://github.com/id-Software/wolf3d
Thanks I appreciate that! Love getting feedback :)
Code-wise I didn't take inspiration from anywhere, I followed "C Programming - A Modern Approach" and based my C knowledge off there. There was also a YouTube video I watched regarding raycasting, and watching people optimise Minecraft etc.
Other than that, its just been alot of trial and error and trying many, many different ideas out.
What has helped is I don't worry about cross-platform ability, I just implement what I want and what feels fun and "innovative".
But I have never seen anyone do a Raycaster with as many vertical/z-levels as I'm planning (1000's), maybe the most I've seen is ~10.
Also most of the approach I'm taking is not best-practice, I'm trying to come up with how to approach everything from my own mind which has been extremely rewarding

#677I've been working on The Road to Next [0] for almost a year. In the end, it's more than just a course on Next.js. It's a deep dive into full-stack development, covering key third-party integrations that empower you to build your own products. [0] https://www.road-to-next.com/
Oh hell yeah, your Road to React was exactly what the doctor ordered when I first waded my way into the full stack ocean years ago. I'm excited to see how this progresses!
That's great to hear :)

#678I've recently been prototyping a mobile application to track your food nutrition. The key feature lies in auto-detecting the food based on a given image, and breaking it down into it's ingredients and then into it's macros. Existing apps such as MyFitnessPal and HealthifyMe fall into two ends of the spectrum where you either need to add ingredients one by one, or your food is logged with a standard macro count where…
I thought about this too, if you need any help let me know, email in bio.
Thanks! I'll send you an email sometime if I make any progress on it! :D

this idea has been rinsed and repeated many times already. unless you're going to include manual input in addition to the image recognition, it will be highly inaccurate
Oh yeah, manual input is going to be a big part of it.
The system should ideally try to map the image to a standard recipe with the ingredients and then hand over control to the user to make any modifications they like.
Computing the nutrients from the ingredients should be reasonably accurate post this because that has a direct mapping in the USDA FoodCentral dataset.

Not sure if you are already familiar but I use Cal AI and think it does a pretty decent job. How granular do you track the macros? hard to figure out from a picture if I used some cheese or how much oil.
Indeed, I intend on having the user take over after identifying the food that we're working with.
The idea is to reduce the amount of redundant work (clicking a button to add a single ingredient over and over again), and rather push for minor modifications instead.
