TileIR is NVIDIA’s MLIR-based compiler for CuTile that lowers high‑level tensor ops through a sequence of dialects (cuda_tile → nv_tileaa → nv_tileas → NVVM/LLVM → SASS) to produce GPU binaries. Using a Mixture-of-Experts kernel as a running example, the post traces how CuTile’s tile-centric model is compiled: abstract CUDA tile ops become explicit memory/tile ops, then tiled memory and tensor-core ops, async pipelines, and finally NVVM/LLVM intrinsics and SASS. It covers Passes, the TileIR tool (tileiras), memory layouts, scheduling, TMA descriptors, and some undocumented CUDA 13.1 details.

Zig's 2026 devlog describes moving libc functions into Zig's standard library wrappers instead of vendored C sources, deleting about 250 C files (2032 remain). This yields independence from third-party libc, faster compilation, smaller installs and binaries, and front-end optimization by sharing the Zig Compilation Unit across libc and Zig code (effective LTO). With std.Io changes, it hints at potential io_uring I/O looping and leak-detection ideas (not yet tried). Report libc issues to Zig first. Abolish ICE.

GitHub Status page documenting ongoing and past incidents across several services. Current updates show degraded performance and failures in GitHub Actions (hosted runners), with related impacts on Copilot, Dependabot, and Actions-triggered features; Codespaces errors creating/resuming; and Pages degradation. Past incidents include repo creation latency and authentication service disruptions, plus Windows runner regressions. Root causes cite upstream provider issues, database connections, and load-pattern-related failures; mitigations and follow-up RCA planned. Subscribers can receive email, SMS, Slack/webhook alerts; status by region is available via regional pages.

Anki’s founder dae announces stepping back from day-to-day leadership after 19 years, transitioning operations and open-source stewardship to AnkiHub to reduce bottlenecks and support sustainable growth. AnkiHub commits to keeping Anki open source, no external investors, and a transparent governance model. The teams aim to improve UI/UX, resilience (bus factor), expand to more learners, and strengthen the add-on ecosystem, while maintaining current pricing. The move is to be gradual, with ongoing community input and public updates; AnkiDroid and current subscriptions remain as is.

Researchers at SINTEF, with Swiss partner COWA Thermal Solutions, have created a compact thermal battery that stores heat from heat pumps using salt hydrates (phase-change materials). The unit charges when electricity is cheap and releases heat on demand, enabling more efficient, space-saving storage—up to four times smaller than a hot water tank. Efficiency rises from ~65% to 85%; charging time drops ~70% and heat release time >80%. The system uses recycled aluminium fins with a plasma electrolytic oxidation coating to resist corrosion and is part of the EU Sure2Coat project.

Stelvio is an open-source Python framework to build and deploy modern AWS apps using pure Python, no YAML or DSLs. The stlv CLI makes infrastructure code feel like regular Python, with smart defaults, automatic permissions, live development mode, and full control over logic and infrastructure in a single file. It provides high-level components for Lambda, API Gateway, EventBridge Cron, S3, DynamoDB, SQS, SNS, and SES. Quick start: uv init, uv add stelvio, uv run stlv init, uv run stlv deploy. Apache 2.0 licensed; community-driven with a roadmap.

AI makes coding easier and cheaper, so being “just a developer” isn’t enough. The article argues you must: 1) acquire deep business-domain knowledge to understand incentives, constraints, and customers; 2) broaden beyond code to full-stack work, operations, security, product thinking, and marketing; 3) build your own apps or revenue streams to gain walk-away power. In short, combine technical skill with business understanding and ownership to stay indispensable.

Fuel Finder is a UK government service that helps drivers locate the cheapest fuel by publishing current petrol prices and forecourt details for the UK. Data published to third‑party apps/websites include prices by fuel type, station address, operator/brand, amenities, opening hours, and update timestamps (prices updated within 30 minutes). Access options: CSV download (twice daily), email subscription for the latest CSV, or a REST API with OAuth 2.0. Anyone can use it (developers, organisations, academics, journalists, individuals). Prerequisites: GOV.UK One Login and API basics.

Commonly, 64-bit unsigned max is 2^64−1 (0xFFFFFFFFFFFFFFFF). The article asks for the largest number that can be represented or computed within 64 bits, not just stored. It traces from BB(6) bounds on Busy Beavers to Melo’s Number produced by a 49-bit lambda-term that already exceeds Graham’s Number. It then defines w218, a 61-bit lambda-term construction, giving BBλ(61) ≥ Melo’s Number and BBλ2(63) as lower bounds. Conclusion: the current 64-bit-representable record is w218.

Greg Miller argues downtown parking lots drain economic potential and should be made financially unsustainable. Using Syracuse, NY as a case study, he shows parking lots represent about $44 million in non-exempt land value (6% of total), yet generate little tax revenue compared with offices and multifamily buildings. Parking idle land suppresses development, raises rents, and reduces vibrancy. Reform involves removing parking minimums, imposing maximums, and smart street parking; crucially, shifting taxes from buildings to land value (land value tax) to deter idle land and encourage development.
