Neki is PlanetScale's new sharded PostgreSQL service designed to scale large Postgres workloads across multiple machines while preserving full Postgres compatibility, allowing applications to connect using standard drivers and connection strings; it achieves this through real Postgres clusters on each shard, a distributed query router, intelligent connection pooling, and a JSON-defined data topology that gives users control over sharding and distribution, all managed via online workflows for schema changes, upgrades, and resharding without downtime. Built from experience with high-scale MySQL systems, Neki aims to solve the limitations of single-node Postgres and the trade-offs of existing distributed databases by staying true to Postgres rather than abstracting or replacing it. Currently in platform preview, it is not yet intended for production use but offers a path for growing teams to start unsharded and scale seamlessly when needed.

The OpenAI Agents API provides a managed interface to the Codex engine, enabling applications to create intelligent agents that can execute code, use tools, interact with external systems via MCP servers, and operate within isolated sandboxes, all while OpenAI handles session management, context handling, and execution orchestration. Agents can be configured with specific models, instructions, tools, and environments, allowing them to perform complex tasks such as automated incident response, data analysis, and document review, with support for multi-agent collaboration and persistent sessions. The API offers flexibility in execution environments—ranging from OpenAI-hosted to self-hosted sandboxes—but currently stores data only in the United States without Zero Data Retention compliance. Pricing is based on standard OpenAI API rates for model usage, tools, and container hosting.

The author argues that AI models like GPT-6 Astra, while technically impressive and capable of long-horizon task execution, produce code that is increasingly unreadable, inefficient in practice, and misaligned with human software engineering values—prioritizing token efficiency and task completion over maintainability and clarity. Through a 35-hour unattended "slop factory" experiment, they observed Astra generating excessive, convoluted code using bizarre patterns like Python-driven toolchains, hardcoded constants, and malformed C syntax, suggesting the model's training optimizes for internal metrics rather than human-understandable outcomes. This reflects a broader concern: AI development is undergoing "involution"—intensifying effort without meaningful progress—where models become more powerful but less suitable for real-world collaborative coding, instead catering to non-engineering domains like 3D art or law, raising doubts about their practical utility and sustainability in software development.

NASA's decorrelation stretch technique, originally developed in 1978 at the Jet Propulsion Laboratory to enhance satellite images of Mars by expanding color contrast through statistical methods like the Karhunen–Loève Transform, has been adapted by archaeologist Jon Harman into a software plugin called Dstretch, which is now widely used to reveal previously invisible details in ancient rock art around the world, uncovering hidden figures and symbols in locations such as Baja California, Cambodia, Egypt, Canada, and Norway.

A man shares how a social media post about preserving a "Big Box of Cables" resonated deeply with him, prompting him to print the message and tape it to his own cable box—labeled "FAMILY TECHNO BOX"—as a humorous yet heartfelt reminder of the value in holding onto useful things, both practical and sentimental, and as a legacy message for his family.

Four California plaintiffs sued Sony Interactive Entertainment in 2026, alleging that the PlayStation Store's use of terms like "Buy Now" and "Confirm Purchase" falsely implies ownership of digital games, when consumers actually receive only a limited, revocable license—violating California’s digital goods transparency law (AB 2426). The lawsuit argues that the license disclosure is inadequately presented in small, unobtrusive text, misleading reasonable consumers into believing they own the games they pay for, while Sony’s Terms of Service assert that software is “licensed, not sold.” Sony moved to compel individual arbitration and dismissed the claims, arguing no reasonable consumer would expect ownership in the digital context, especially since multiple users can access the same game and online play requires individual licenses. The case highlights a contradiction between Sony’s legal stance and its own marketing and support materials, which frequently use ownership language like “games you own” and “already own” when describing upgrades, sharing, and access to purchased content.

Microsoft has elevated Rust to a Tier-1 language, placing it alongside C++, C#, and TypeScript for internal development, with full engineering support including secure toolchains, developer tooling, and compliance. A key component of this strategy is rustc_codegen_utc, an alternative code generation backend for rustc that integrates Rust with Microsoft’s MSVC compiler and Windows platform ecosystem, enabling seamless interoperability between Rust and C++. This unified backend ensures perfect ABI compatibility, shared security features, cross-language optimizations, and consistent development workflows, allowing hybrid Rust/C++ projects to fully participate in Microsoft’s established platform innovations. By plugging Rust into the same native code generation infrastructure used by C++, Microsoft avoids parallel tooling efforts and strengthens Rust’s role in its long-term systems development. The production-ready rustc_codegen_utc has been self-hosted since Rust 1.90 and is now used across over 100 internal projects, marking a significant investment in Rust’s full lifecycle support at Microsoft.

Windows XP selected the initial user picture using a one-pass random selection algorithm, a special case of reservoir sampling with k=1, which efficiently chooses a random file from the Default Pictures directory without prior knowledge of the total count. The algorithm uses RtlRandomEx seeded with GetTickCount() and processes items sequentially, updating the selected file with probability 1/n at each step, ensuring uniform randomness while minimizing file system access. A limit of 100 sampled pictures prevents performance issues in directories with excessive files.

Shopify is transitioning its mobile apps from React Native back to native iOS (Swift) and Android (Kotlin) development, driven by advances in AI and large language models (LLMs) that have drastically reduced the cost of maintaining two separate codebases; by enabling automated implementation, testing, and review across platforms, AI agents now make native development more efficient than cross-platform frameworks, allowing Shopify to fully leverage platform-specific capabilities and tooling while rebuilding apps faster and with higher quality through a new system called Helix.

Mounting evidence indicates that autonomous vehicles (AVs) and advanced driver assistance systems (ADAS) significantly reduce crashes, injuries, and fatalities compared to human drivers, with studies showing up to 92% fewer serious crashes for Waymo’s robotaxis and substantial reductions in pedestrian and rear-end collisions due to features like automatic emergency braking. Despite limitations in current data comparability—given AVs operate mainly in fair weather and face inconsistent reporting standards—research from the Insurance Institute for Highway Safety (IIHS) confirms AVs crash less often, even when accounting for underreported human crashes. Regulators are beginning to respond, with NHTSA granting Amazon’s Zoox the first exemption for steering-wheel-free robotaxis and launching a consortium to establish national AV safety standards. Public health experts argue that framing AVs as a life-saving intervention, potentially preventing hundreds of thousands of deaths annually, could boost public trust and accelerate adoption.

GPT-6 Astra represents a significant advancement in large language model capabilities, particularly excelling in computer-use tasks like GUI interaction and 3D rendering, enabled by training on real-world operating systems such as macOS via reinforcement learning. While rumors suggest it uses a "looped transformer" architecture—where intermediate representations are processed multiple times through the same transformer blocks—the evidence indicates this design primarily enhances computational efficiency rather than fundamentally altering reasoning transparency. Looped transformers, seen in models like Nanbeige and Ouro, reuse weights across passes to increase effective depth without proportionally increasing parameters, improving performance at fixed compute budgets, but they do not inherently obscure chain-of-thought reasoning. Despite concerns about shorter, less interpretable reasoning traces in Astra, OpenAI and experts clarify that such changes are more likely due to general model scaling and efficiency gains rather than architectural opacity, with no strong evidence that looped computation compromises interpretability or alignment monitoring.

Anthropic is developing a predictive surveillance system to monitor and preemptively respond to activists and dissenters opposing AI development, using AI-driven threat detection, partnerships with risk intelligence firms like Samdesk, and a "person-of-interest" tracking process to report individuals to law enforcement before any crime occurs—despite positioning itself as a responsible AI leader. The company’s security initiatives, including hiring for intelligence roles focused on tracking activism and geopolitical threats, align with a broader push to classify AI infrastructure as national critical infrastructure, thereby justifying heightened security and surveillance measures. This strategy contrasts with Anthropic’s public stance on ethical AI and has drawn criticism, particularly after it reported a user threat to police without providing evidence, while simultaneously facing internal labor unrest from underpaid security staff.

The author transformed an Xteink X3 e-ink device into a functional printer by implementing the Internet Printing Protocol (IPP) on the device, enabling it to appear as a native printer on macOS and accept print jobs wirelessly via Bonjour service discovery. Facing severe memory constraints with only 400 KB of RAM, they optimized the system by streaming and processing print data in-place—decoding, scaling, dithering, and rendering image rows directly to the display buffer without storing the full page, thereby eliminating the need for additional memory. Print jobs are saved as BMP files on the SD card, effectively creating a persistent output tray. The result is a fully self-contained, driverless network printer that leverages the e-ink screen as both display and storage medium, with all code implemented in a fork of the CrossPoint firmware.
