Collabora and Valve are developing Holo Core, a pure aarch64 port of Arch Linux for the Steam Frame. They publish aarch64 preview binaries, sources, and development containers to enable exploration. Challenges include cross-arch building, dependency ordering, and Arch's rolling releases; time and upstream changes complicate replay. They built a CI-driven build replay toolchain to produce a fully functional aarch64 package tree and aim to shadow Arch Linux development with future CI. The article also outlines how to use the preview with QEMU/distrobox and how to build packages, with plans to open tooling to the community.

The article analyzes why Muon, a function-space optimizer, destabilizes Transformer QK updates and sketches both principled and practical paths. It argues the constraint should target the final output—attention scores S = QK^T—rather than constraining W_Q and W_K separately. A Muon-style QK objective with ||ΔW_Q W_K^T + W_Q ΔW_K^T||_2 ≤ ε is mathematically elegant but computationally heavy due to pseudoinverse steps. A unified approach with B = W_QW_K^T recovers Muon but is parameter-heavy. The piece links low-rank MHA to LoRA (Muon-LoRA) and advocates pragmatic interventions: gradient clipping (MuonClip), max-logit spectral-norm proxy, and forward/backward tweaks, noting hyperparameter sensitivity.

An instructional post on building a MikroTik-based home router for a homelab. The author uses a MikroTik L009UiGS-RM to prioritize wired networks, with PoE for a Wi‑Fi AP, and CAPsMAN for centralized Wi‑Fi management. They outline ISP handoff choices (IPoE vs PPPoE) and IPv4 types; for their fiber, PPPoE over VLAN 35 with private IPv4 and a DS-Lite caveat. Setup steps include cloning the ISP router MAC to the WAN port, adding VLAN 35, creating a PPPoE client, and establishing default routing. Wi‑Fi APs are managed by CAPsMAN. They mitigate bufferbloat with FQ-CoDel and queue shaping, and disable fastpath.

Natural experiments show iron fertilization of nutrient-poor oceans reliably boosts phytoplankton and draws down carbon. Irons from undersea vents, Sahara dust, volcanic ash, wildfire smoke, ice-derived minerals, and whale feces trigger blooms that rise and then fade when inputs stop, with little evidence of harm. The Tonga vents fueled nitrogen-fixing bacteria and two- to eightfold faster growth, with two to three times more carbon buried. Similar responses occur across the Atlantic, Pacific, and Southern Ocean, often lasting months. Deliberate, monitored nutrient additions are comparably safe to nature’s ‘fertilizer’ events.

Texas DPS spent about $4.49 million to equip four 2026 Chevrolet Tahoes with Cognyte’s FalcoNet surveillance system, including core hardware, a 5G license, and antennas. The emergency purchase memo emphasized safety needs but gave few specifics. FalcoNet can bulk‑collect private data by tapping mobile connections, raising Fourth Amendment privacy concerns; Florida has already deployed it, and The Drive outlines the system’s components and deployment kits.

SoundCloud's upgraded AAC encoder (Fraunhofer libfdk_aac) improves perceptual quality, but trims energy above ~17 kHz to save bits. Lossy encoders allocate bits across bands; since human hearing is less sensitive to highs, reducing top frequencies frees bits to sharpen the midrange. At 256 kbps the effect is smaller but still present. The result: tracks may look worse on a spectrogram yet sound better in practice.

Draws a parallel between parallel programming and human life. More power alone doesn’t yield results unless work is divided, communicated, and synchronized so no part is overloaded. Honest internal communication acts as synchronization, preventing burnout. Echoing Zen, inner harmony comes from fully experiencing and finishing what arises, not clinging to residue. The greatest limit may be power divided against itself—in machines and in people, not simply a lack of power.

Kimi K3 has seen demand exceed capacity, causing a temporary pause on new subscriptions to protect current subscribers; existing subscribers are unaffected. The team is adding capacity and will reopen new slots in batches. Going forward, Kimi will split membership into two plans: Kimi Membership for Web, App, and Work; and Kimi Code Membership for coding workflows, to better match compute and stabilize the experience. Thanks for patience.

The final MPEG-4 Visual patent, BRPI0109962B1 ("process for storing and processing image information from successive images over time"), expired in Brazil on July 19, 2026, according to VIA Licensing Alliance, ending MPEG-4 Part 2 patent coverage.

Nick Gustafson's "Holding the LLM Stack in Your Head" is a concise, opinionated map of the modern LLM stack, from linear algebra to agent protocols, presented as ten arcs totaling ~80 posts. It treats the material as a learning exercise (with Claude Opus 4.8), prioritizing intuition over rigor. Topics span prerequisites, language modeling before Transformers, tokenization, transformer fundamentals, decoding/inference, serving systems, training/post-training, evaluation, retrieval/memory/context engineering, and tools/agent loops. It provides practical paths for understanding attention, KV cache, RAG, and agent loops, with caveat that it's a first draft.

The Vox explainer traces how “dupe culture”—cheap lookalikes of name-brand products—has become a mainstream, internet-driven phenomenon. From UGGs and Fender to makeup and recipes, dupes blur lines of ownership as platforms and tools (dupe.com, AI image search, TikTok Shop) make finding cheaper lookalikes easy. It discusses legal gray areas around design patents and trademarks, the culture of affordability over originality, and how algorithms encourage copying while still fueling aspirational consumer desires.

Cagire is a Forth-based live coding sequencer in which every step runs a Forth script, letting scripts synthesize sound, trigger samples, apply effects, or do anything you define. It uses a built‑in audio engine called Doux with oscillators, samplers, filters, reverb, delay, distortion, etc. A second language, Arf, lets you write DSP inside braces. It supports synthesis, sampling, modulation, sequencing, MIDI/OSC, Ableton Link, recording and visuals, with built‑in documentation. Cross‑platform and open source (AGPL-3.0); downloads and source on Gitea.

Proposes WIP/RFC: UnifiedIR, a new top-level Julia package to unify the compiler IR data structures (SyntaxTree, SyntaxGraph, CodeInfo, IRCode, and others) into a dialect-aware, region-based IR substrate. Ports inference, the optimizer, and JuliaLowering to UnifiedIR; supports layered views and extensible dialects, enabling ecosystem use. Integrates with Base bootstrapping and JuliaSyntax, JuliaLowering; demonstrates a unified storage core with graphs and trees, plus tooling for provenance, printing, and verification. Aims to replace multiple data structures and ease extensibility across the compiler stack.
