- This is very cool, just some UX tips to make it more legible:
1. remove ~50% of the UI since it covers too much of a laptop screen
2. improve the camera controls so its easier to pan and zoom.
by npunt - It surely is impressive,but it’s just that - components of db service as buildings/machine. What it needs is narrative, purpose, with main actors clearly defined - client and data. demonstrating what is involved in the chain when data’s written and requested.by dostick
- Try the tour. It’s exactly that.by computomatic
- I don't know what I am looking at but it is fabulous.by loveparade
- I assume this is done with the help of AI? I have done similar vibe project that explaining catastrophic forgetting with the help of AI. It's just so satisfying now that if you really want to learn something, you can always do it with the help of AI. Before, it's hard to find good resources, now it's not a problem, the issue now becomes one's own focus and agency.by WiSaGaN
- I have a pretty good working knowledge of the internals of Postgres, but this just confused me. I think it's too busy to understand. At the very least, it would be cool if there were a "slow down" button.by jedberg
- There are buttons on the bottom left: pause and two to adjust the speed (down to 0.1x). Some parts of the city can be adjusted when you click on it (I just found the transactions/s)by augunrik
- This is very similar to what I imagine whenever I get into a deep focus state debugging a program in gdb... I would love to experience debugging a program in VR with graphics like this,,, there would be no better way to learn a codebase. I wonder how good an experience you could achieve by generating a 3d map based on arbitrary codeby willquack
- Considering that it has been vibe-coded with not even 48 hours passed: Is this truthful and accurate at all? Or will it lead to false conclusions and anti-knowledge?
- LLMs aren't that bad anymore.by fragmede
- Glean anything or learn something in particular?
This is a brutalist gew-gah.
by itomato - Not entirely sure, but the person vibe coding this does know Postgres really well tbfby parthdesai
- I can't believe "Rendering The First Frame..." is not "Reticulating Splines..." :)
Cool UI.
by arjie - Understanding how scheduling works inside a database used to require numerous architecture diagrams to explain. I was amazed when I saw PGSimCity — it presents such a complex technical implementation process in such an engaging way. Since it's already open‑source, I think the same idea can be reused in other domains, such as cloud computing, Kubernetes, and so on.by Curtis_Guan
- I keep wanting to build a Kubernetes visualiser. I know they exist, but the last time I looked they didn't look that great.
- I've always wanted to do an explainer of the deployment system and state-tracking at Fly.io using Factorio as a visual metaphor.by tptacek
- The limiting factor of your human brain is the same limiting factor the reader has to function with. You can get the LLM to aid in making something, but at a certain level of greebling, [0] it just doesn't feel like it's meant to be experienced by another human being, you know? The sacrifices you'd have to make by NOT building this with an LLM would be made because you COULDN'T fit the mental model of everything going on here in your head. The user has got a similar brain with similar limits.
I'm trying to understand the metaphors here, or how all of the animations and flashing lights are meant to represent something going on, but it all sort of gets lost in the sauce. I'm not sure why a new process is represented by a square that goes through a tube and ends up at a building and then the pinball switch glows red. I click on a thing and a popup says "sessions is the victim" with another paragraph of small text, then disappears a couple seconds later? What?
To be fair, I wont assume this is meant to teach me! Always the possibility of a skill issue on my part and I just lack knowledge here. Taking it at face value as a neat thing, it's neat.
by graypegg - I imagined as soon I saw the initial visual that I would somehow be able to enter a query and it would walk me through the flow through the entire system starting from input parsing to all the way to delivering output and perhaps along the way understand some of the autonomous processes that happen in parallel that aren't query specific but run constantly.
What others are saying - fantastic attempt, but don't know where to start or where to end.
by narmiouh - try pressing Tby samokhvalov
- I love what is trying to be done here. Some feedback to improve would be to cut out a lot of the noise with the "Take tour". There are too many boxes and things changing on the screen to get a sense of what is happening. Also make it interactive rather than automatically switch onto the next subject. Being a passive observer to so much information trying to be conveyed is very confusing.
I really do like these kinds of approaches to showing the inner workings of different kinds of tech, so think this is on the good path to being a very useful tool, but needs some focus rather than more data/graphs/info boxes.
by layoric - This is good general advice. If your software needs a "tour," that's a good indicator you should work on your UX instead. If you're just excited to tell the user about a new feature, they'll discover it when they need it.by andyfilms1
- maybe try adding tts to the tour?by derac
- It's amazing 3D going on, and then 80% of the visual space is popups that completely block it. It'd be have a nice prominent ways of reducing the noise, and that pops were partially transparent.by titzer
