Redis 8.8: New array data structure, rate limiter, performance improvements

Redis 8.8 introduces a dynamic, general-purpose array data type (with ARRING ring-buffer support), a window-counter rate limiter (INCREX), Streams NACKing (XNACK with SILENT/FAIL/FATAL), subkey notifications for hash fields, multi-aggregator time-series queries, and explicit FP type control for JSON numeric arrays (FPHA with BF16/FP16/FP32/FP64). It also adds a COUNT aggregator for sorted-sets unions/intersections. End-to-end throughput gains (e.g., MGET up to 68%, XREADGROUP up to 83%), and faster persistence/replication (up to 60%).

At the Autograph Show

Kevin Jack McEnroe writes about loving and protecting his mother, actress Tatum O’Neal, while navigating addiction, illness, and fame. Through stories of overdoses, a stroke, autograph shows, hospital stays funded by her work, and tense boundaries, he learns to say no and stop blaming himself. He argues that modeling a different life—loving without sacrificing one’s own peace—is key to helping an addict. The piece blends resilience, compassion, and hard-won integrity as he reflects on family, fame, and the cost of care.

Ohbin – uv wrapper for installing tools from GitHub

Ohbin declaratively manages GitHub-release binaries for uv projects via pyproject.toml. Instead of per-tool wrapper packages, a single engine downloads, verifies (SHA256), caches, and execs the tool on first use. Tools are declared under [tool.ohbin.tools.*], with repo, version, and platform-specific assets; ohbin add fills the manifest and pins checksums. uv run ohbin run resolves the tool, downloads if needed, and execs it, with caching in ~/.cache/ohbin. It supports concurrency-safe downloads, retries, and integrity checks. Discovery walks up to the nearest pyproject or uses OHBIN_PYPROJECT. Limitations: POSIX-only; Windows import fails; linux/darwin x86_64/arm64; others must be added.

There's no escaping it: an exploration of ANSI codes

ANSI escape codes are a 50-year-old standard that encodes terminal control in text streams: cursor moves, formatting, and colors. A CSI sequence (ESC [) is interpreted by modern terminals to perform actions; e.g., \x1b[31m red text, \x1b[1m bold, \x1b[0m reset, \x1b[2J clear screen, \x1b[H move to 1,1). Attributes join with semicolons; m is the Select Graphic Rendition command. Original 8 colors; today supports 256 colors and true RGB (\x1b[38;5;208m, \x1b[38;2;255;128;0m). Libraries and full-screen UIs extend these for rich CLIs, and the post includes an interactive widget to experiment with codes.

Entanglement Builds Space-Time. Now "Magic" Gives It Gravity

Quanta reports that in holographic theories, space-time emerges from quantum entanglement, and a quantum property called “magic” (non-Clifford gates) provides the link to gravity. After models where space and matter entanglement were decoupled, Cao, Preskill and colleagues built a quantum error-correcting code in which abundant non-Clifford gates let space and matter entanglement influence each other. Magic makes space bend; gravity arises from imperfect quantum encoding. It’s an early, concept-stage step (0.5 of 5) toward quantum-gravity simulations.

Leap in DNA synthesis slashes time to build new genetic sequences

IEEE Spectrum reports Sidewinder, a low-cost DNA-synthesis method that lets AI-designed sequences be built in parallel with high accuracy. It can assemble dozens of sequences in a single test tube, with one wrong junction per 10 million events—far better than conventional methods. The approach uses barcoded oligos and three-way junctions; a compact PyWinder tool on a laptop designs the barcodes. In tests, it redesigned a 12,500-letter E. coli genome in silico and synthesized it from scratch in days, not months. It could enable large DNA constructs for drugs, biofuels, data storage, and synthetic organisms; Genyro aims wide academic access.

Linear Cosine Palettes(2025)

Danielle Navarro explains a lightweight method for generating continuous color palettes for generative art using linear cosine palettes: f(t) = a + b cos(2π(c t + d)) with base colors a,b,c,d. Provides an R implementation (cosine_palette) and a utility (shade_strip) to display palettes. Runs 12 seeds (11–22) to visualize outputs, showing how palettes influence subdivision-based and Lissajous-based artworks. Results are varied but generally promising; palette alignment not optimized. The post emphasizes keeping it short and practical rather than a full monograph. Based on Mike Cheng's post and Inigo Quilez' cosine palettes.

Watching a Z80 from an RP2350

Kevin experiments with the RP2350 (Pimoroni PGA2350) and PIO to interface with a Z80 bus. He wires Z80 address (A0–A15) and data (D0–D7) plus control lines to RP2350 GPIO and uses two cores to snapshot the bus and drive LEDs. He covers Z80 basics (clocking, M and T cycles, /WAIT, and reset timing) and notes clock-speed considerations. A simple RC2014-style 8-bit IO module demonstrates IO reads: when /IORQ and /WR indicate an access to IO address 0, the data bus value lights the LEDs. Future work includes full IO handling, memory-mapped devices, clock control, and more autonomous operation.

Fine-tuning an LLM to write docs like it's 1995

An independent, non-commercial experiment by Fabrizio Ferri Benedetti demonstrates fine-tuning small LLMs to imitate late-90s Microsoft technical writing using Bitsavers corpus (1977–2005). He scraped and cleaned 37M+ words, produced 192,456 JSONL training examples with synthetic prompts, and trained adapters via QLoRA on Llama 3.1 8B Instruct and Qwen 2.5 7B Instruct using Runpod GPUs, cost about $50 and one day. Results: fine-tuned models generate period-appropriate structures (synopsis, Return Value, man-page style) and even convincing REST API chapters; smaller adapters can better impersonate; base models fail. Fine-tuning augments but cannot replace human writers.

Pass the Cherries: Review of Twilight of the Dons

William Whyte reviews Colin Kidd's Twilight of the Dons, a historical study of British intellectuals at Oxford and Cambridge from 1950–1980 and their collapse under Thatcher. Kidd defends a 'golden age' of open, cosmopolitan dons and argues Thatcherism damaged British culture by turning dons from the nation's conscience into a 'luxury cruise liner' for an international clientele, leaving a vacuum. Whyte lauds Kidd's depth, style and the mix of general history and stand-alone essays, but questions scope (omitting many academics outside Oxbridge and other universities) and whether 'decline' is the right frame; notes shifts to private enterprise and media.

The Pentagon is running an AI propaganda mill targeting Latin America

An Intercept investigation shows La Tilde, a Latin America–targeting site funded by the U.S. government, operates as an AI-driven propaganda outlet for the Pentagon. La Tilde mixes personal-finance guides with fawning coverage of U.S. military actions (e.g., Maduro’s abduction) and discloses government funding in About page. It appears linked to SOCSOUTH/SOUTHCOM messaging, with no staff bylines and AI-generated content; production involves contractors like General Dynamics and Antpack. Plans to launch country-specific versions suggest broader influence operations.
