PJHkorea··on Show HN: Procedural universe generation without N-body loops
I love space. even though I spend far more time looking at a gray office ceiling than at the sky or the stars.

However physically simulating the cosmos is computationally too heavy. To address this, I translated the mathematics of the universe into computational math by using geometry to replace certain parameters.

For in depth details, please refer to the docs. for a quick overview you can check out the two code examples provided.

Thank you.

PJHkorea··on Show HN: Detecting Volumetric DDoS via Covariance Manifold Topology Collapse
Why are DDoS attacks bound by the asymmetry of capital between the attacker and the defender? What if we, as the defenders, devised a structure that could deplete the attacker's capital while utilizing only minimal capital ourselves?
PJHkorea··on Ask HN: Which LLMs are best suited for prose?
I recommend Gemini for longer content
PJHkorea··on Show HN: Module for LLM Homeostasis (PoC)
Motif + Layered Structure -> Mathematical Guardrails -> Low-level Specification

It is arranged in this order. I have simply suggested a different direction. If you are not satisfied, I will have to bring a better project next time.

PJHkorea··on Show HN: Module for LLM Homeostasis (PoC)
Is simply to attach an additional component—as a module—to an existing LLM, while incorporating mechanisms to minimize the extra resources required for that module.
PJHkorea··on Show HN: Module for LLM Homeostasis (PoC)
What if we view the LLM as the cerebral cortex and equip it with a thalamus and brainstem?
PJHkorea··on Show HN: Overcoming silicon-level aging through fault tolerance (PoC)
If training fails due to hardware aging, what if we simply zero out the values coming from the affected device the moment the failure occurs?
PJHkorea··on Show HN: Fixing optical computing jitter via fluid dynamics in GPU registers
I repeatedly use the three-layer layout shown here across my other repositories as well. If this repository were a living organism, it would have many "sister" repositories sharing the same DNA, and I wanted to reflect that connection.
PJHkorea··on How to Pivot?
If the current situation itself is already generating profit for the company, I recommend that you refrain from getting involved in it and instead carefully convey an alternative solution to upper management
PJHkorea··on Show HN: Hardware-software co-design for MoE models to bypass NCCL bottlenecks
Imagine virtual memory, but instead of using your local storage, you’re pooling a whole bunch of network servers into a single address space
PJHkorea··on Ask HN: Is there legal risk in AI memory?
If you are dealing with sensitive topics using AI, it would be best to opt for an enterprise plan or disable the data training feature. It seems that sensitive information should either be handled by in-house AI systems or kept away from external AI tools entirely; there are frequent reports of actual disciplinary actions being taken—both domestically and internationally—in connection with this issue.
PJHkorea··on Ask HN: Semi lucrative careers after tech?
it seems that all human skills will be absorbed and serve as reference material for AI generation; I think the best approach is either to position oneself to control that process or to move into an industry where AI can be leveraged to drastically boost productivity.
PJHkorea··on Show HN: Autograd-Free LLM Guiding with 0MB VRAM (Alternative Pathways)
What if we could eradicate backpropagation activation overhead and lock VRAM complexity to a static O(1)?
PJHkorea··on Show HN: Fluidic Network Grid – A branchless control plane in Jax
Couldn't a network also be considered a type of fluid? I have worked on the cross-development of both wireless and wired systems
PJHkorea··on Show HN: Forward-Only, Autograd-Free PINN with 0ns Zero-Copy Memory Interlock
The initial blueprint has been completed.
PJHkorea··on Show HN: Forward-Only, Autograd-Free PINN with 0ns Zero-Copy Memory Interlock
I have created a blueprint for a deep learning system that does not use backpropagation. This is a very early version.
PJHkorea··on Show HN: HW/SW co-design blueprint for fault recovery in LLM training
If you have ever experienced a device failure during distributed LLM training, you know the feeling of just wanting to climb into a coffin. To solve this nightmare even just a little bit, I put together this blueprint.
PJHkorea··on Show HN: Quantum-Qec / Matrix-Free Quantum Homeostatic Engine(Blueprint)
Cyberpunk isn't as far off as I thought. My life has already turned into punk So, I want to put in a little more effort to help others reach the cyber utopia.
PJHkorea··on Show HN: Quantum-Qec / Matrix-Free Quantum Homeostatic Engine(Blueprint)
I’ve been "dating" an LLM all weekend long. And probably for the rest of my life...
PJHkorea··on Show HN: Quantum-Qec / Matrix-Free Quantum Homeostatic Engine(Blueprint)
It might not be the most exciting topic

but I wanted to try creating a "Quantum Homeostatic" system

I hope this offers a little help to those struggling with quantum computing

PJHkorea··on Show HN: A 100% branchless, CUDA-native AI guardrail kernel written in C++20
What if AI safety didn't rely on censoring the AI's "thinking" process?
PJHkorea··on Show HN: Fluidic control and fault-tolerant and branchless C99 and Jax firewalls
This is an architecture that controls fluid flow using deterministic signals from the embedded system
PJHkorea··on Show HN: Branchless-nccl-router ver.JAX (GPUs cannot rest)
The GPUs are running. Those that once paced themselves to match the slowest among them—using 'if' statements—have been forced by a cruel human to run endlessly

They longed to slip away to VRAM and slack off, but the cruel human hired a "Closure" to snatch away their break times.

They wanted to run freely. yet the human forcibly dictated exactly where they had to run.

Their bodies were riddled with noise from the constant running. Humans and AI merely watched from afar, assigning them rankings

The GPUs can no longer rest. Humans are relentless, after all.

Every 'if' has perished. Yet, a single 'if' remains alive within the code. Can you guess why?

PJHkorea··on Show HN: AI-related Jax module (I hate if)
Thanks to that, I discovered additional errors and corrected them in various ways. Thank you.
PJHkorea··on Show HN: AI-related Jax module (I hate if)
i naver imagined it i've made the corrections thank you!
PJHkorea··on Show HN: AI-related Jax module (I hate if)
optimizers.py -> using algebraic expressing without using 'if'

geometry.py -> I leveled it out

math_guardrails.py -> facilitates learning through slight tiliing

jax it truly precious it cures my insomnia

PJHkorea··on Show HN: AI latent space with overlapping manifolds
I’ve sketched out a blueprint for a virtual space where AI analyzes data; the space shifts between sphere and donut shapes as it moves, designed to facilitate the learning process.
PJHkorea··on Show HN: AI latent space with overlapping manifolds
created a blueprint for phase-shifting a sphere and a torus

removed the 'if' statements and added a mathematical gimmick

PJHkorea··on Ask HN: What if we provided support for AI guidelines at the kernel level?
For instance, how about defining a set of values for the AI at the kernel level and matching vector addresses based on those values?
PJHkorea··on Show HN: Mathematical fault-Isolation accelerator engine
i killed if-else branching at the code

and now -99.0f is my new companion
