UNIX-like/POSIX-compliant operating systems provide atomic operations for thread-safe and multi-process-safe programs without mutexes or locks. These operations include mv -T, link, symlink, open, mkdir, and fcntl, which can be used for file and directory locking, creating new files and directories, and synchronizing access to files.
GPT-5.3-Codex is a new model that advances coding performance, reasoning, and professional knowledge capabilities, enabling long-running tasks and real-time interaction. It sets a new industry high on coding benchmarks and demonstrates strong performance on real-world tasks, making it a general-purpose agent for technical work.
There are two main software development approaches: gradual evolution of complexity over time and big up-front design with a detailed specification.
The user shares their personal journey of adopting AI tooling, starting with a period of inefficiency, then adequacy, and finally workflow and life-altering discovery, highlighting the importance of using agents with external behavior capabilities. They outline their approach to harnessing AI, including breaking down tasks, verifying agent work, and "harness engineering" to prevent mistakes, ...
Artifact Keeper is an open-source artifact registry that can be self-hosted in minutes, offering a drop-in replacement for JFrog Artifactory and Sonatype Nexus with zero feature gates. It supports 45+ package formats and has features like security scanning, SSO, replication, and a WASM plugin system.
The user experimented with a new approach called "agent teams" where multiple Claude instances work in parallel on a shared codebase without human intervention, successfully producing a 100,000-line Rust-based C compiler that can build Linux 6.9 on x86, ARM, and RISC-V. The user learned how to design harnesses for long-running autonomous agent teams, including writing tests, structuring work, ...
The DoJ's latest Epstein archive release has several issues, including censored names, corrupted files, and poor OCR results due to the use of Courier New font and low-quality JPEG scans.
To optimize PostgreSQL performance, understand settings like shared_buffers and work_mem, which control memory usage and disk interaction, and adjust them based on real metrics and system statistics. Properly sizing shared_buffers (20-25% of total RAM) and work_mem (3-4MB per GB of RAM) can prevent memory pressure, disk spills, and out-of-memory errors.
The Tower of Fantasy game shipped with a kernel driver that has BYOVD capabilities and weak authentication. The driver can be exploited to kill and shield processes from antivirus and EDR agents.

The author, a CI expert, criticizes GitHub Actions for its poor usability, slow performance, and complex configuration. They recommend Buildkite as a better alternative.
Some communities have developed techniques to help them carry heavier loads. Here's what we can learn from them. The rural farm workers of Vietnam could be seen as almost superhuman. Every day, they shoulder impressive loads strung to a pole before carrying them for up to several miles at a time by foot. The awkward, bulky packages of produce, tools or other materials can often weigh more ...
The author reflects on George Orwell's novel 1984, which was published in 1949 and depicted a dystopian future where the government exercises total control over citizens. The author argues that Orwell's vision of a totalitarian society was not as prescient as people think, and that many of the technological and social aspects of the novel are outdated and inaccurate.
MenuetOS is a 64bit assembly OS with pre-emptive multitasking, GUI, and multiprocessor support. It's written in 64bit assembly for speed and compactness, with a responsive GUI and support for various applications.
User found a Remote Code Execution vulnerability in AMD's AutoUpdate software due to lack of certificate validation and HTTP download URLs. AMD considered it "out of scope" and did not consider it a vulnerability.
The author of tldraw is considering shutting down external contributions due to an influx of low-quality AI-generated pull requests. They argue that code is now easy to write with AI tools, making external contributions less valuable.
Pro and Max users who started their subscription before February 4, 2026, at 11:59 PM PT, get a $50 credit for extra usage with Claude Opus 4.6. The credit can be claimed from February 5 to 16, 2026, and expires 60 days after claiming.

Scott Aaronson discovered his name in the Epstein Files, showing Epstein's attempts to fund a research project with him in 2010, which he largely blew off after his mom's advice to be cautious. Aaronson reflects on how he was not alone in being approached by Epstein, but notes that many scientists who interacted with him were either charmed by him or prioritized his funding over their reservations.
Standard neural networks fail to handle hierarchical data where observations are grouped into distinct datasets with hidden parameters, leading to flawed conclusions and overfitting. Hypernetworks offer a solution by learning to generate dataset-specific parameters based on a dataset embedding, enabling flexible and data-efficient adaptation while pooling knowledge across datasets.
Agent teams are experimental and let you coordinate multiple Claude Code instances working together, but have known limitations and use significantly more tokens than a single session.
The author discusses "expect tests" that make test-writing feel like exploratory programming, with the computer filling in expected results. This style of testing is convenient and encourages implicit assertions, making it easier to catch unexpected issues.
A few years ago, back when GPT-3.5 was first released, and I still spent most of my days sitting in a high school classroom, I had a project idea. Perhaps one of my best named project ideas to date: The Generative Pen-trained Transformer or GPenT for short. GPenT was awesome, I was going to build out a color-changing pen plotter with some funky coreXY-esque kinematic, and alongside it, try my ...
The author proposes creating a "Company as Code" system to represent organisational structure, policy, and operations programmatically, making it easier to manage compliance, track changes, and automate processes. This system would use a declarative Domain Specific Language (DSL) to define entities and relationships, connected to real-world data through a storage strategy and integration framework.
The user sets up a Python environment, installs requirements, downloads a local LLM model, and starts services including LLM, orchestrator, and UI. This process can be automated using Windows batch scripts for easier management.
Collabora Office is a new desktop release offering a powerful office experience on Windows, macOS, and Linux. It's based on LibreOffice and offers long-term support, enterprise features, and customizable solutions.
