Beads is a lightweight memory system for coding agents, using a graph-based issue tracker with hash-based IDs to prevent collisions. It provides a centralized database via git, allowing agents to query and update a shared database across machines.
Polar Night Energy and Lahti Energia partnered for a 2MW sand battery project in Finland, reducing fossil emissions by 60% annually. The project will supply heat to Lahti Energia's district network and participate in grid balancing markets.
GitLab's Vulnerability Research team has identified a large-scale supply chain attack involving a destructive malware variant spreading through the npm ecosystem. The malware contains a "dead man's switch" mechanism that threatens to destroy user data if its propagation and exfiltration channels are severed.

The author discusses improving I/O performance by using io_uring and kqueue APIs to submit requests to the kernel for readiness and completion events, allowing for batching and amortizing system call overhead. A central dispatcher is built to handle I/O requests and completion events, providing a simple API for scheduling I/O and passing callbacks for event completion.
European governments have taken another step toward reviving the EU’s controversial Chat Control agenda, approving a new negotiating mandate for the Child Sexual Abuse Regulation in a closed session of the Council of the European Union on November 26. The measure, presented as a tool for child protection, is once again drawing heavy criticism for its surveillance implications and the way it ...
The user discovered four indicators in Chocolate Quake netcode: TURTLE, DISC, RAM, and NET, which were likely intended for developers and map designers to diagnose performance issues. These indicators show up on screen when the framerate drops below 10fps, HDD access is slow, the engine evicts surfaces from cache, or a client hasn't received packets from the server in 300ms.
Positron is a next-generation IDE for data science with features like a data explorer, interactive console, and AI assistance. It supports R and Python, has a familiar interface, and is extensible with thousands of VSX extensions.
MAXduino is a digital tape emulator for various retro computers, supporting TAP, TZX, WAV files, and more. It's a cost-effective solution for loading digital files onto multiple retro machines, including ZX Spectrum, Amstrad CPC, and MSX.
As a team grows, feedback becomes harder to process due to the lack of personal relationships and context. Leaders must build systems and processes to filter and synthesize feedback at scale.
The user reminisces about their elementary school days and shares their experience with a chess-enthusiast teacher who created a large chess board in the schoolyard. They then discuss the history of the Domain Name System (DNS) and how it has evolved over time, including the failed attempt to implement a hierarchical naming system in the US with RFC 1480.
Peter Shor's algorithm can break RSA and elliptic curve cryptography by solving factoring and discrete logarithm problems in polynomial time. This makes all current public-key cryptography vulnerable to quantum computers, which can decrypt previously encrypted data.
For developers integrating Haskell into data science workflows or interactive documentation, the Jupyter notebook is the standard interface. Currently, there are two primary ways to run Haskell in Jupyter: IHaskell and xeus-haskell. While both achieve the same end user experience (executing Haskell code in cells) their internal architectures represent fundamentally different engineering ...
The user designed a modular mechanical calculator with a simple design, but encountered several challenges, including gear misalignment and slipping. They eventually created a working version using involute gears and a new fastening system with rotating pegs.
Going indie offers freedom but also loneliness, pressure, and constant decision-making. It's a demanding yet rewarding experience that requires handling multiple roles and responsibilities.
HN community members share gratitude for the site's enduring quality and meaningful discussions despite some decline in discourse. They appreciate the community's refuge from online absurdity and thank founders for creating this space.
User implemented Robin Hood hashing for a hash table and compared it to unordered_map, finding a 2x performance advantage. The implementation's performance is influenced by CPU cache and data locality, making it viable for lookup caches.
Google's Tensor Processing Unit (TPU) is a custom ASIC designed for AI tasks, offering better performance per watt and cost-effectiveness compared to Nvidia GPUs. The TPU's unique systolic array architecture and Google's optimized ecosystem make it a significant competitive advantage for Google Cloud's business.
