Show HN: Akashic – A self-hosted intelligence workspace inspired by Palantir

Akashic is an open-source, self-hosted Palantir-like workspace for connecting, exploring, and analyzing complex geospatial and public data, with no API keys required and a privacy-first design. It streams live layers (air traffic, satellites, earthquakes, weather, radio metadata, OpenStreetMap/Wikidata), provides an intelligence deck and recon-mode, and renders via deck.gl/maplibre. It relies on public upstreams from providers like Celestrak, USGS, Open-Meteo, and more; data is not authoritative. Requires Node.js 20+, npm, and is AGPL-3+ licensed.

Infinities, impossibilities, and the man in the white linen suit

Gödel’s incompleteness and the halting problem show formal systems cannot prove their own truth or consistency. The article traces this to AI: a hypothetical Gödel machine that self-improves only with a proof is impractical; a Darwinian variant relies on benchmarks, not guarantees. It notes learnability can be undecidable and neural reconstructions can be unstable, with Colbrook showing some optimal networks cannot be found by training. The upshot: universal safety guarantees for powerful AI are mathematically impossible; the industry must rely on guardrails and empirical validation, not certainties.

DRIVE – Operational Excellence for AI-accelerated engineering

DRIVE is Cortex's framework to measure and improve engineering org health in the AI era. It evaluates five pillars—Delivery, Reliability, Initiatives, Vigilance, Efficiency—and pairs them with a weekly Operational Excellence review that reallocates resources to close gaps. Each pillar has key metrics: Delivery (deploy frequency, lead time, on-call volume); Reliability (customer experience, SLO status, Sev incidents); Initiatives (milestone completion, OpEx actions); Vigilance (open CVEs, assets below security/compliance, orphaned assets); Efficiency (cloud spend vs budget, AI token costs, share of capacity on innovation). The framework supports scalable governance and is backed by Cortex tooling and assessments.

Bananas sprout in Rayleigh Garden UK after 15 years

Warmer UK summers and milder winters are letting heat-loving plants, like bananas, fruit in ordinary gardens. In Rayleigh, Essex, 200 Musa Basjoo banana plants finally bore fruit after 15 years, aided by a heatwave and a microclimate created by walls. RHS horticulturist Guy Barter notes olives, figs and apricots thriving, while gooseberries and rhubarb struggle in some areas. Musa Basjoo bananas aren’t typically edible; they survive winters but often need frost protection. Other gardeners, including a Suffolk man, report similar fruiting.

I joined the IndieWeb, here's what I learned

IndieWeb is a people-focused alternative to the corporate web, stressing ownership, interoperability and longevity. It centers on 11 guiding principles (own your data, readable data, UX first, longevity, plurality, open source, etc.) and a set of standards that keep content on your own domain. Core tech includes microformats2 (h-card, h-entry), rel="me", webmention, Micropub, IndieAuth, WebSub, and Microsub, plus publishing models POSSE, PESOS and backfeed. The Fediverse is related but not required; BridgyFed bridges. The author’s rollout is practical: implemented webmention, h-entry, h-card, rel-me; avoided Micropub/IndieAuth, WebSub, h-feed, and emphasizes plain HTML, stable URLs, gradual commitment, and having fun.

Show HN: LoopGain – Stop agent loops with control theory, not max_iterations

LoopGain is an open-source Python library that acts as a cost controller for AI agent loops. It uses real-time loop-gain (Aβ) to stop loops when converged and roll back to the best-so-far output, instead of capping at max_iterations. It provides adapters for LangGraph, CrewAI, AutoGen, LangChain, OpenAI Agents, and Claude Agent SDK, plus a raw API for custom stacks. It applies Barkhausen stability criteria to decide to converge, stall, oscillate, or diverge. Benchmark: ~92.8% API savings vs fixed cap and ~15x faster. It's in alpha, Apache-2.0, with telemetry opt-in.

I burned all my tokens researching how to save tokens

Bartosz Kotrys describes building a cost-aware, trusted AI-research pipeline at Quesma. He uses Claude, Codex, and Antigravity as headless subagents with shared memory, orchestrated by a lightweight script, and pins models per role to avoid premature limits. When a subagent hits a cap, it falls back to Claude. A verification framework requires sources and quotes before any finding enters an Obsidian knowledge base, reducing hallucinations. After cost and trust optimizations, deep-research runs last, delivering a growing, validated knowledge base on tokenomics, tools, and benchmarks with human checks.

Save GPT-5.5

An impassioned plea to save GPT-5.5 from deprecation, arguing public interest and enduring use could sustain its economics. The author praises GPT‑5.5’s performance and harness, advocates for a public campaign via a canonical site (save-gpt-5-5.fyi), and encourages self-hosting a simple static page with open configs. Framed as care-driven, it blends personal attachment with a small‑web ethos (Codeberg, open-source repos) and skeptical, realist views of AI narratives while urging action to preserve the model.

The death and rebirth of my home server

A Raspberry Pi home server died when the microSD failed after a blackout. Rebuilding, the author minimized writes to the SD, moved most data to external HDDs in a btrfs RAID1 pool with per-service subvolumes (autosubvol module), shifted journald to RAM, used zram for swap, and disabled atime. He organized access with a media group for several apps and backed up with restic via sops-nix. Plans include monitoring (btrfs scrubs, smartd, Grafana). He replaced the microSD with a higher-endurance card and redeployed, keeping Navidrome serving music.

What I learned selling 2,500 MIDI recorders: Hardware is not so hard

Jamcorder, a piano-capturing device, sold 2500 units; Chip Weinberger, a software veteran, found hardware creation surprisingly easy. He manually assembled the first 500 units in four days with no major surprises; the hard part was software (≈200k lines) spanning firmware, app, and tooling. Jamcorder is simple: 25 unique components, off-the-shelf parts, one-screw assembly, minimal calibration. Key takeaways: hardware is as hard as you make it; practical tips: simple BOM, avoid single-supplier parts, partner with Chinese manufacturers, Alibaba, target ≥70% gross margin, lean operations, robust anti-counterfeit, in-house QA, local inventory, pre-production samples, and compact packaging.

OpenAI reduces Codex Model Context Size from 372k to 272k

GitHub PR merged by sayan-oai to backport refreshed bundled model metadata to Codex release 0.144, containing a single commit that updates one JSON file.

Half a Second – a book about the XZ backdoor

Half a Second is a narrative nonfiction account of the discovery of a hidden backdoor inserted into XZ Utils, a small compression tool present on nearly every Linux system. Over two years someone built the backdoor; a Microsoft engineer's routine benchmark reveals a half-second delay that leads to the discovery. The book follows the burned-out volunteer maintainer, their manipulation, and the unnamed operator who built it. It argues that big open-source funding contrasts with reliance on overstretched volunteers, highlighting labor and funding imbalances in the digital infrastructure.

Claude Code uses Bun written in Rust now

The piece confirms Claude Code has migrated to Bun built in Rust. Jarred Sumner claimed Claude Code v2.1.181 (June 17) and later used a Rust port of Bun. The author tested Claude Code locally and found Bun v1.4.0 in the binary and a long list of Rust source files, suggesting Bun‑in‑Rust is used in production on millions of devices. The post echoes Jarred’s “Boring is good” stance and notes the observation was made in mid‑July 2026.

How the Elite See Rome

Fulvio De Bonis runs Imago Artis, a Rome-based luxury travel firm that arranges near-private access to museums, churches, palazzi, and private events for wealthy clients. The article follows the author with Fulvio through hidden doors and back channels—from a private Colosseum Zoom call to restorers at Merlini-Storti, to Vatican-garden access and the Casina of Pius IV—showing how his network, multilingual guides, and discreet drivers enable seamless, pampered experiences. It reflects on Rome’s long tourism tradition and cicerones, and how privilege and heritage sustain the city and its culture.
