Global high-performance proof-of-stake blockchain with erasure coding
Research reference implementation of the Alpenglow consensus protocol. Getting Started A local cluster example can be run with the following command: This spawns a local cluster with 6 nodes. These nodes communicate via UDP on localhost. Console output from the fastrace crate shows the progress of all nodes. Further, we provide the simulations binary target. […]
Show HN: AutoThink – Boosts local LLM performance by 43% with adaptive reasoning
I built AutoThink, a technique that makes local LLMs reason more efficiently by adaptively allocating computational resources based on query complexity. The core idea: instead of giving every query the same “thinking time,” classify queries as HIGH or LOW complexity and allocate thinking tokens accordingly. Complex reasoning gets 70-90% of tokens, simple queries get 20-40%. […]

Using Postgres pg_test_fsync tool for testing low latency writes
Here’s a useful tool for quickly testing whether a disk (or a cloud block store volume) is a good candidate for your database WAL/redo logs and any other files that require low latency writes. The pg_test_fsync tool is bundled with standard Postgres packages, so no extra installation is needed. You don’t actually have to use […]
High-quality OLED displays now enabling integrated thin and multichannel audio
A research team led by Professor Su Seok Choi of the Department of Electrical Engineering at POSTECH (Pohang University of Science and Technology) and PhD candidate Inpyo Hong of the Graduate Program in Semiconductor Materials and Devices has developed the world’s first Pixel-Based Local Sound OLED technology. This breakthrough enables each pixel of an OLED […]
A privilege escalation from Chrome extensions (2023)
What’s the worst thing a Chrome extension could do to you? Well, it could steal your passwords and cookies, or it could continuously close your tabs. Obviously, these are bad and annoying, but there are limitations to the power of extensions. Can they run exe files? Not really. They can download files at any time, […]
Look Ma, No Bubbles Designing a Low-Latency Megakernel for Llama-1B
There are some applications that benefit from running LLMs really, really fast. This low-latency regime encompasses applications like chatbots and human-in-the-loop workflows, where users care a lot about seeing responses come back immediately. Given the importance of these low-latency workloads, we wanted to explore just how fast we can run open-source models on modern GPUs. […]
A UEFI app that sends LLDP-MED pkt at boot to negotiate PoE+ power before the OS
Back in 2015, I was working on a project to build PoE-powered embedded x86 computers and digital signage systems. These were full Windows 10 Professional machines running Intel Atom processors, designed to simplify deployment by drawing power directly over Ethernet. Our goal was to eliminate the need to run traditional AC power to these devices, […]
OpenTPU: Open-Source Reimplementation of Google Tensor Processing Unit (TPU)
OpenTPU is an open-source re-implementation of Google’s Tensor Processing Unit (TPU) by the UC Santa Barbara ArchLab. The TPU is Google’s custom ASIC for accelerating the inference phase of neural network computations. Our design is based on details from Google’s paper titled “In-Datacentre Performance Analysis of a Tensor Processing Unit” (https://arxiv.org/abs/1704.04760), which is to appear […]
