Firefox 157 will include JPEG XL by default on all platforms

Mozilla plans to enable JPEG XL decoding by default in Firefox 157, using the jxl-rs Rust decoder, previously behind image.jxl.enabled on Nightly (Firefox Labs checkbox). It ships alongside Safari 17.0; Chrome remains behind a flag. Multithreaded decoding patches landed; benchmarks show JXL is competitive with Safari on large images but slower on small ones. HDR tone mapping is strong; animated JXL is supported. Extensive tests and fuzzing accompany the rollout. Some warn lossless JXL decodes ~30× slower than WebP, with ~10% savings, suggesting a lossy-first approach.

Pgbot: A 5.9 MB read-only Postgres tool for humans and agents

pgbot.dev is an open-source Postgres intelligence platform that gives AI-powered explanations and actionable insights about database health and performance. It connects to any PostgreSQL database—directly or via the pgBot Agent for private environments (Docker, Kubernetes, VPCs)—and supports cloud DBs like Supabase, Neon, and RDS. Features: real-time health monitoring, slow-query and regression analysis, table/index analytics, vacuum visibility, and AI root-cause recommendations. It’s read-only by default, with a deterministic MCP toolset for AI agents to inspect data (no writes) and private deployments allowed.

Dolly Parton has died

Dolly Parton, the country star, actor and philanthropist, has died aged 80, announced by her nephew on Instagram. A prolific songwriter of Jolene and I Will Always Love You, she earned 25 US country No.1s, 47 Top-10 albums, and pop hits such as 9 to 5. She acted in films and built a business empire around Dollywood and Sandollar. Her Imagination Library has mailed ~25 million books, and she funded literacy and health causes, including backing Moderna vaccine development. A May 2026 Las Vegas residency was cancelled for health reasons; a Broadway musical is planned.

OpenAI Jalapeño: Better than Nvidia Blackwell

OpenAI’s Jalapeño is a generalized AI inference ASIC designed in-house (with Broadcom) to maximize tokens-per-watt, not just optimize one model. It uses HBM4 with 15.4 TB/s and a scalable 2,048-XPU rack network. A0/B0 silicon shows strong perf/W against Rubin/others, with STP throughput: 700+ tok/s at concurrency 1 on DeepSeek R1 and ~1,400 tok/s/user on Kimi-K2.5/GPT-OSS; tapeout Nov 2025; production ramp 2027. It combines MXFP-like compute, 64-bit scalar cores, Gluon/Triton kernels, and no prefill-decode disaggregation to preserve locality.

Run Minecraft in a Windows Sandbox for Computer Use Agents

Boot a Windows sandbox, install Minecraft Java Edition, and drive the game from an agent via cua-driver’s MCP server inside the sandbox. The guide covers running Minecraft in a Windows VM locally or on Fleet, including software OpenGL via Mesa llvmpipe, signing in with Microsoft accounts through Prism Launcher, and playing under MCP control. A one-time cost is building a containerDisk image (disk.img) with Prism, Java, Mesa, and the game, exportable as an OCI image. Fleet uses a service proxy, requires GALLIUM_DRIVER=softpipe and client-credentials MCP tokens, and has tips for local vs Fleet setups and troubleshooting.

LatticeDB – Like SQLite but for graph databases

LatticeDB is an embedded, single-file knowledge-graph database with native vector search (HNSW) and BM25 full-text search, designed for local apps on a single machine with a zero-config, single-writer model. It stores the entire database in one portable file and provides graph traversal, vector similarity, and text indexing in one query layer. It also supports durable streams and built-in change feeds. Aimed at Graph RAG, agent memory, and local knowledge tools, with Python/TypeScript/Go bindings (core in Zig). Benchmarks show sub-microsecond node lookups and ~0.83 ms 1M-vector searches. Not a server DB; for networked scaling use Neo4j/PostgreSQL.

Run OpenBSD on DigitalOcean for $4/month

OpenBSD on DigitalOcean for about $4/month: a DIY guide to run a minimal OpenBSD server on a Droplet using a custom miniroot79 image. Upload the miniroot, create a Droplet (512MB RAM, 1 vCPU, 10GB), set up autoconf IPv4/IPv6, create a non-root user, enable sshd, disable root login, and install only necessary sets (http), removing X, games, compilers. Optional full-disk encryption. Reboot and SSH in as the non-root user; harden by disabling password authentication. Read the OpenBSD Handbook and FAQ; nostalgia for DIY Unix; hosted on Netlify.

A new ceiling for Λ: the de Bruijn–Newman constant is at most 0.1787854

Jude Gomila reports a computer-assisted proof that the de Bruijn–Newman constant Λ ≤ 0.1787854, improving the previous 0.2 bound. Using Polymath 15’s Theorem 1.2, the proof implements three finite checks: (i) RH is machine-verified below a barrier up to a verified height; (ii) at final time t0 no zeros lie to the right of the barrier; (iii) a one-unit barrier across X ≤ x ≤ X+1 and y in [0.1809,1] stays zero-free for 0≤t≤t0. With t0=129/800 and y0^2=87677/2,500,000, Λ ≤ t0 + y0^2/2 = 893927/5,000,000 = 0.1787854. An independent audit by Dan Romik confirms the result is unconditional.

Tooltips Need a Delay, and Then They Need to Skip It

Abhishek Jakhar explains a UX pattern for tooltips: avoid instant tooltips on simple cursor sweeps by using a 200ms open delay and a 300ms cooldown after closing, creating a 'warm window' where moving between adjacent triggers opens tooltips instantly. Implemented with Radix/Motion in React using a shared TooltipProvider and a warm ref; leaving a trigger cancels the open timer; hovering during cooldown keeps the page warm. The result trades micro-interaction delay for smoother navigation; includes code walkthrough and notes on taste, with a Claude skill to audit codebases.

Water Behind the Watts: The Hidden Risk of Powering Data Centers

Water Behind the Watts shows data centers’ water risk mainly from power generation, not cooling. In seven states (VA, TX, CA, IL, GA, OH, AZ) that host about half of U.S. data centers, electricity uses ~3.4 trillion gallons of freshwater annually. About 78% of electricity comes from water-using plants, and 66% of those plants are in areas of medium-high to extremely high water stress. Many operators and investors overlook water risks linked to the electricity they buy. The report calls on producers, operators, policymakers, and financiers to pursue cleaner energy and better water stewardship.

Visualizing Binary Files

The post describes bine, a Python ncurses-based hex editor that colorizes output by rendering special ASCII glyphs in the text column to indicate NUL and non-printable bytes, avoiding expensive per-byte color calls. To visualize large binaries, the author maps bytes to a Portable Graymap image (PGM), deriving width/height and exporting PGM for viewing in image viewers. Examples include EXE, tarball, ruff, ISO, and an 8 GB disk image. The approach is fast and non-destructive, but has limits for very large files due to memory/RAM when using ImageMagick. It highlights practical data inspection via simple, post-processed visualization.

AI is hitting entry-level jobs hardest, Stanford study finds

Stanford economists update their Canaries in the Coal Mine study, showing AI's impact is strongest for entry-level workers. Using ADP payroll data and AI-exposure measures (Anthropic Economic Index), they find 22- to 25-year-olds in the most AI-exposed occupations now have 19% lower employment than peers in less exposed fields (up from 13%). The drop is driven by lower hiring rates, not higher quits or layoffs. Automated-use roles show steeper declines; augmentative AI use shows muddier effects. Higher codified knowledge and education buffer some impacts, but entry paths for new workers are narrowing.
