The research demonstrates that AMD Zen 2 and Zen 3 systems are vulnerable to Rowhammer despite TRR mitigations, expanding the attack surface. A new method, ZenHammer, triggers bit flips on DDR4 and DDR5 devices for the first time, with Zen 3 being more vulnerable. By reverse-engineering secret DRAM address functions, the team found reliable results […]
Radio communications are crucial in modern electronics, but the underlying theory can be daunting for hobbyists. This article aims to simplify the concepts, focusing on antennas and electromagnetic waves. By visualizing electric fields using charged particles, the creation of antennas from charged capacitors is explained. Half-wavelength dipole antennas are highlighted for their efficiency and resonance […]
In this post, we delve into the architecture of Google’s First Tensor Processing Unit (TPU v1) and its performance objectives. The TPU v1 project aimed to develop an ASIC that would provide a 10x cost-performance advantage on inference compared to GPUs, all while being cost-effective and scalable. The TPU v1 utilized a systolic array approach […]
SPQR 2.0 is finally here, bringing new syntax for sharding configuration. To set it up, use commands like CREATE DISTRIBUTION, ATTACH RELATION, and CREATE KEY RANGE to route values to different shards. Sharding Rule syntax is now outdated, with the focus on improved Extended Protocol support. Smart shard rebalancing is crucial for workload balance, with […]
Author explores Deno’s optimization for fast Foreign Function Interface (FFI) calls using V8 Fast API Calls. The traditional method involves a lot of type checks and jumps, slowing down the process. Deno introduced Turbocall, a tiny assembler in Rust, to generate optimized bindings for FFI calls based on type information. This led to 100x faster […]
Exosuits are a promising technology that aids in body movement, but face challenges like muscle fatigue. Scientists in South Korea and Switzerland are working on the Synapsuit, a powered exoskeleton system that aims to combat fatigue using controllably stiffening materials. The system includes an electrostatic clutch that holds joints in place between muscle-driven movements without […]
In 1908, Harry Houdini, known as “The World’s Handcuff King and Prison Breaker,” needed a new act. He had toured all over the United States and Europe, challenging authorities and performing daring stunts. From escaping metal safes in Russia to being submerged in water-filled milk cans, Houdini pushed the boundaries of entertainment. Described as an […]
