GPT-5's Shockingly Good Search Capabilities: Meet My Research Goblin

The author discovered OpenAI's GPT-5, combined with Bing's search capabilities, possesses surprisingly powerful search functionalities. It tackles complex tasks, performs in-depth internet searches, and provides answers, earning the nickname "Research Goblin." Multiple examples demonstrate GPT-5's prowess: identifying buildings, investigating Starbucks cake pop availability, finding Cambridge University's official name, and more. GPT-5 even autonomously performs multi-step searches, analyzes results, and suggests follow-up actions, such as generating emails to request information. The author concludes that GPT-5's search capabilities surpass manual searches in efficiency, particularly on mobile devices.

Trump Admin Seeks to Revoke Key Climate Change Finding

The Trump administration proposed revoking the 2009 endangerment finding, which established that greenhouse gases endanger public health and welfare, thus underpinning numerous climate regulations. EPA Administrator Lee Zeldin claims this is the largest deregulation in US history, but environmental groups fiercely oppose it, arguing it ignores worsening climate disasters. The move could eliminate tailpipe emission limits and hamper future climate action, leading to likely legal challenges.

nnd: A Blazing Fast, Lightweight Native Debugger for Linux

Meet nnd, a Linux debugger inspired by RemedyBG, prioritizing speed and lightweight design. It boasts a TUI interface, is built largely from scratch (not based on gdb or lldb), and handles large executables efficiently (tested on a 2.5GB ClickHouse executable). nnd focuses on speed; instantaneous operations are truly instantaneous, while longer operations are handled asynchronously with progress bars. Currently, it only supports Linux x86-64 native code debugging and lacks remote debugging, multi-process support, and reverse stepping. Distributed as a single 6MB executable with no dependencies, it's easily installed via curl or built from source.

Training Long-Horizon Terminal Agents with Reinforcement Learning: Terminal-Bench-RL

This project details the creation of a stable RL training infrastructure scaling to 32x H100 GPUs across 4 nodes for training long-horizon terminal-based coding agents. The author developed Terminal-Agent-Qwen3-32b, achieving the highest score on terminal-bench for Qwen3 agents *without* training! Built upon the rLLM framework, it includes custom environments and infrastructure. Using ~$1M in compute, the agent achieved 19th place on the terminal-bench leaderboard, outperforming several top agents from Stanford and OpenAI. A sophisticated system prompt and custom tools guide the agent's behavior. While a full training run was cost-prohibitive, the code and dataset are provided, inviting further research with increased compute resources.

PostgreSQL 18 Beta: Asynchronous I/O Revolutionizes Performance

2025-05-07

PostgreSQL 18 Beta 1 introduces highly anticipated asynchronous I/O (AIO), marking a significant leap in I/O handling. AIO dramatically improves performance, especially in cloud environments with high latency, by allowing the database to issue multiple read requests concurrently. Currently limited to reads (writes may be added later), AIO utilizes a new `io_method` configuration parameter offering synchronous, I/O worker, and `io_uring` modes. `io_uring`, on compatible Linux kernels, delivers the best performance. Benchmarks on AWS show 2-3x read performance improvements for read-heavy workloads. However, AIO changes performance monitoring; `EXPLAIN ANALYZE` I/O timing may be less precise, requiring the new `pg_aios` view for detailed analysis.

C++26: The Unnamed Placeholder `_` Arrives

2025-01-11

C++26 introduces a game-changing feature: the unnamed placeholder `_`. This solves a long-standing annoyance in C++: handling unused variables. Previously, developers needed `[[maybe_unused]]` or `std::ignore` to avoid compiler warnings, especially with structured bindings. The `_` placeholder can be declared multiple times without conflict and implicitly has the `[[maybe_unused]]` attribute, simplifying code and improving readability. This feature is already implemented in GCC 14 and Clang 18.

AI's Energy Hog: Data Centers Face a Power Crisis

The rapid growth of AI is creating a massive energy demand, catching many enterprises off guard. Research reveals that while most companies are aware of AI models' high energy consumption, few monitor actual power usage. High-performance GPUs and complex AI models are the main culprits. To address this, efficient AI hardware and more effective cooling systems (like liquid cooling) are crucial. Data centers need upgrades to handle higher power density, requiring substantial investment and time. Some companies are exploring using waste heat for regenerative power generation or community heating.

Denmark Revives Controversial Child Sexual Abuse Scanning Bill

On its first day as EU President, Denmark has reintroduced a controversial bill aimed at scanning messaging services for child sexual abuse material (CSAM), dubbed 'Chat Control'. This proposal, which mandates scanning even encrypted chats, has failed to garner sufficient support since May 2022, raising concerns about privacy and the undermining of encryption. Denmark, a strong supporter, aims for adoption by October 14th, but details of compromises remain undisclosed.

Procedurally Generating Forest Creatures: A Long and Challenging Journey

The author spent years working on procedurally generating and animating a large number of forest creatures for their game, The Big Forest. Initially, they tried using simple parametric models, but the results were unsatisfactory. They then shifted to manual parameterization and used Principal Component Analysis to find higher-level parameters, but the results were still not ideal. Ultimately, they abandoned automated solutions and instead manually defined higher-level parameters, developing tools to assist in parameter adjustment. For animation, the author built upon previous research, using a kinematic approach and continuously refining it to achieve more natural creature movement. The entire process was challenging but also enjoyable, and the author shares their experiences of trial, error, and improvement.

Ammonia-Fueled Ship Viking Energy Delayed Until 2026

The world's first full-time ammonia-fueled ship, Viking Energy, originally slated for launch in 2024, has been delayed until 2026 due to the complexities of building the necessary ammonia infrastructure. Ammonia's toxicity, explosiveness, and corrosive nature require specialized piping, storage, and transport. Furthermore, ammonia combustion produces nitrogen oxides, necessitating emission control technologies. Despite challenges, experts believe ammonia will eventually become a mainstream marine fuel. They suggest seaports become energy hubs producing, storing, and trading alternative fuels to solve the chicken-and-egg problem of fuel supply and ship construction.
