Fast uniform load with wave ops (up to 64x speedup)
In shader programming, you often run into a problem where you want to iterate an array in memory over all pixels in a compute shader
group (tile). Tiled deferred lighting is the most common case. 8x8 tile loops over a light list culled for that tile.
Simplified HLSL code looks like this:
Buffer<float4> lightDatas;
Texture2D<uint2> lightStartCounts;
RWTexture2D<float4> output;
[numthreads(8, 8, 1)]

ollama+DSPy using OpenAI APIs.
# install DSPy: pip install dspy
import dspy
# Ollam is now compatible with OpenAI APIs
#
# To get this to work you must include `model_type='chat'` in the `dspy.OpenAI` call.
# If you do not include this you will get an error.
#
# I have also found that `stop='\n\n'` is required to get the model to stop generating text after the ansewr is complete.
# At least with mistral.

Great and less great SSDs for Ethereum nodes

Overview

Syncing an Ethereum node is largely reliant on IOPS, I/O Per Second. Budget SSDs will struggle to an extent, and some won't be able to sync at all.

This document aims to snapshot some known good and known bad models.

For size, 4TB comes recommended as of mid 2024. The smaller 2TB drive should last an Ethereum full node until early 2025 or thereabouts, with crystal ball uncertainty. Remy wrote a migration guide to 4TB.

High-level, QLC and DRAMless are far slower than "mainstream" SSDs. QLC has lower endurance as well. Any savings will be gone when the drive fails early and needs to be replaced.
