Why I Write (1946)

Orwell’s Why I Write argues that writers are driven by four motives—sheer egoism, aesthetic enthusiasm, historical impulse, and political purpose—and that every book bears political bias. He recounts his arc from a lonely youth with a love of words to a writer who, after imperial Burma and the Spanish Civil War, takes a clear stand against totalitarianism and for democratic socialism. He explains his aim to fuse political purpose with artistic craft (as with Animal Farm and Homage to Catalonia), while insisting that prose should be truthful and clear. Writing is a struggle, and good prose is a windowpane.

TorchTPU: Running PyTorch Natively on TPUs at Google Scale

TorchTPU enables native PyTorch execution on Google TPUs, delivering usability, portability and performance at scale. It uses an eager-first stack (Debug Eager, Strict Eager, Fused Eager) with a shared compilation cache and a static path via Torch Dynamo + XLA/StableHLO, plus custom kernels (Pallas, JAX; Helion in progress). It supports distributed training (DDP, FSDPv2, DTensor) and can handle divergent code (MPMD). The TPU architecture (ICI-based torus, TensorCores, SparseCores) drives hardware-aware optimizations. Roadmap for 2026 includes fewer recompilations, precompiled TPU kernels, public repo, Helion, dynamic shapes, multi-queue, and ecosystem integrations.

GPT-5.5: Mythos-Like Hacking, Open to All

XBOW reports GPT-5.5 offers a Mythos-like leap in vulnerability detection, outperforming GPT-5 and Opus 4.6 on internal black-box/white-box benchmarks. On a vulnerability miss-rate benchmark, GPT-5.5 hits 10% vs 40% (GPT-5) and 18% (Opus 4.6). In white-box with source code, performance nearly saturates the benchmark. In real tasks, GPT-5.5 logs in faster—about half the iterations of the next-best model—and signals failures earlier. It also balances persistence vs pivot better, reducing unnecessary dead-ends. Implications: faster investigations, better coverage, more reliable, multi-model stack; customers gain stronger pentest workflows.

Show HN: Tolaria – open-source macOS app to manage Markdown knowledge bases

Tolaria is a macOS desktop app (Tauri/React/TypeScript) for managing markdown knowledge bases. It supports offline, git-first notebooks (vaults) that you own and can move between editors; no cloud lock-in, open source under AGPL-3.0+. Notes are plain markdown with YAML frontmatter; types serve as navigation aids rather than enforced schema. It aims to be AI-friendly but not AI-only; supports AI agents (Claude, Codex CLI). Getting started involves downloading the release or building locally with Node.js 20+, pnpm, Rust. Vaults are stored as git repositories and can sync with remotes.

How the Tech World Turned Evil

Timothy Noah argues the tech industry has shifted from countercultural liberators to monopolistic power, hostile to regulation. It traces millenarian AI talk—from Thiel’s Antichrist framing to secular Singularity narratives—where government interference is treated as evil and AI as salvation. The piece notes unprecedented private investment ($670B in AI, large GDP share), soaring tech lobbying, and a political realignment toward Republicans. It details how platforms like Meta, Google, and Palantir have vast government ties, and describes “enshittification” as user/merchant predation. It advocates stronger, Europe-style AI regulation and protections against job loss.

Show HN: Agent Vault – Open-source credential proxy and vault for agents

Agent Vault is an open-source HTTP credential proxy and vault that sits between AI agents and the APIs they call. It never reveals vault-stored credentials to agents; instead, it brokers access by routing agent requests through a local HTTPS proxy that injects credentials at the network layer. It supports any HTTP agent, encrypts credentials at rest with AES-256-GCM (optional master password via Argon2id), and can run in passwordless mode for PaaS. Per-vault request logs are kept with configurable retention. Install via script, Docker, or source; use agent-vault run to wrap agents; MIT license with enterprise features.

UK Biobank health data keeps ending up on GitHub

UK Biobank data are repeatedly uploaded to public GitHub, with a tracker listing 110 DMCA takedown notices targeting 197 repositories by 170 developers since July 2025. Notices often target notebooks, genotype/phenotype data, and other files that could reveal participant information; a Guardian investigation showed possible re-identification from minimal data. UK Biobank uses copyright takedowns to remove data, but the UK lacks a privacy DMCA equivalent. Notices originate from researchers worldwide (at least 14 countries); takedowns paused in early 2026 and resumed after media scrutiny.

My phone replaced a brass plug

Vadim Drobinin narrates building an on-device vision system to automate shooting-target scoring while learning venison hunting. Starting with Apple's Vision, he switches to OpenCV to identify ring structures and uses a hybrid approach: adopt a 2012 Rudzinski/Luckner method for hole detection (erase rings, flood-fill, edge detect, Hough circles) and augment it with YOLOv8 for bullet-hole localization, then compute scores from hole centers relative to ring radii. He merges geometry with CoreML, addresses perspective distortions, and tunes bullet-radius scaling. The result is an offline iOS app for scoring cards and tracking shooting performance.

Using the internet like it's 1999

Joshua Blais argues that the internet is dying from algorithmic feeds and siloed platforms. To reclaim agency, he champions a 1999-style approach using open protocols and personal control: RSS for feeds (Miniflux), IRC/XMPP with end-to-end encryption, deliberate search queries, and local/Internet Archive archiving; email for private messages; POSSE to push content to social, not pull; Gopher/Gemini as lightweight alternatives; router blocklists, text-only browsers, and disabling JavaScript for privacy. Emphasize authentic human connection, minimal consumption, and reclaiming sovereignty over online information.

Middle Eastern News Sites Are U.S. Government Propaganda Ops

Investigative reporting by The Intercept shows that Al-Fassel and Pishtaz News are U.S.-government propaganda outlets linked to CENTCOM/SOCOM’s Trans-Regional Web Initiative (TRWI). Disclosures of U.S. funding sit hidden in About pages, while social media labels omit state-backed status. The sites push pro-U.S. and Gulf-aligned narratives, cite CENTCOM, and promote messaging on Iran, Gaza, and regional allies. TRWI began in 2008 to disseminate influence material, later rebranding; some sites have limited reach. Analysts view this as overt information warfare rather than independent journalism.

Advanced Packaging Limits Come into Focus

Advanced packaging limits are now central to manufacturing scalability. Packaging is a performance variable: substrate choice, bonding interfaces, thermal paths, and process sequencing shape system performance. Warpage, driven by thermo-mechanical mismatches and stress, dominates as packages grow and diversify; solutions like glass panels or backside power trade one problem for another. Hybrid bonding increases density but remains highly sensitive to contamination and stress at small pitches. Backside thinning and debris control tighten tolerances. Substrate limits and panel processing add further constraints. A holistic, end-to-end process-stack optimization is needed to scale reliably.

Girl, 10, finds rare Mexican axolotl under Welsh bridge

Ten-year-old Evie Hill found a nine-inch Mexican axolotl under the Dipping Bridge near the River Ogmore in Bridgend, Wales, naming it Dippy. The family returned to Leicester with the new pet. Experts say this is the first documented axolotl sighting in the UK and the species is critically endangered worldwide (about 50–1,000 left). They warn axolotls are hard to care for and should not be released into the wild, advising sightings be reported to the National Centre for Reptile Welfare. Evie’s school is fascinated.

People Do Not Yearn for Automation

Nilay Patel argues in Decoder that AI accelerates 'software brain'—a mindset that treats the world as databases and code. This view explains both AI’s powerful business reach and the growing distance to everyday people, who feel overwhelmed, surveilled, and worried about job loss. He notes polls showing waning enthusiasm for AI even as executives push automation, and highlights the mismatch between law and code, data-center opposition, and the urge to flatten life into data. He calls for democratic, market, and personal resistance to over-automation, and for tech to adapt to people, not the reverse.

I spent years trying to make CSS states predictable

The piece argues that CSS state collisions arise when multiple states overlap, making component behavior fragile in design systems. Rather than chasing complex selectors, the author built a declarative state model (Tasty) that lets you define a priority map for a component's states (hover, active, disabled, theming, media, etc.). The compiler generates non-overlapping selectors so the chosen state is deterministic, simplifying extension and reducing regressions. It grew from decades of work and now powers Cube UI Kit; plain CSS is fine for small pages, but this helps large systems. Feedback is encouraged via GitHub.
