AI & Tech Policy
Leaked OpenAI financials show $38.5B loss and compute burn
Summary: Leaked financials reveal OpenAI lost $38.5B in 2025 while spending heavily on compute infrastructure, despite reaching $13.07B in revenue. The company’s pivot from research lab to hyper-growth business mirrors historic tech boom loss patterns. Much of the loss jump is attributed to a non-cash accounting charge from its conversion to a public benefit corporation.
HN Discussion: Commenters debated whether the trajectory is sustainable: some saw parallels to Firefox’s service-layer model, while others argued hyper-growth losses are standard for big tech. Simonw noted the $13B revenue figure is impressive given OpenAI had negligible revenue four years ago. tptacek cited Financial Times reporting that the bulk of the loss jump is a non-cash accounting charge tied to the corporate restructuring.
GPT‑NL: a sovereign language model for the Netherlands
Summary: TNO, the Dutch research organization, announces GPT-NL, a sovereign large language model built for the Netherlands. The project aims to operate under Dutch and EU data regulations while serving the Dutch language and cultural context. It joins a growing list of national LLM initiatives across Europe including Sweden’s GPT-SW3.
HN Discussion: Skepticism emerged in the Dutch tech scene about the project’s value proposition and cost effectiveness. Some commenters argued national research labs should fine-tune existing open models for local utility rather than build from scratch. Others defended the initiative as essential for linguistic and regulatory sovereignty independent of US and Chinese AI companies.
Stop Killing Games fails to secure EU law despite 1.3M signatures
Summary: The Stop Killing Games European Citizens’ Initiative gathered 1.3M signatures but the European Commission declined to legislate, instead spending time with industry lobby groups. SKG anticipated this outcome and has already shifted strategy to amending the Digital Fairness Act through Parliament, where they claim majority support. The ECI process only compels the Commission to respond formally; it does not force legislation.
HN Discussion: Commenters noted the headline frames a strategic pivot as a defeat: SKG had secured 45 MEPs for a legislative call and expected to push through Parliament. Some questioned whether the proposal as written would reduce the number of online games dramatically. Parallels were drawn to the failed abolish-daylight-saving ECI from a decade ago as an example of signature thresholds not translating to policy change.
Security & Privacy
GrapheneOS has been ported to Android 17
Summary: GrapheneOS has been successfully ported to Android 17, with official builds expected soon. The privacy-focused OS continues to expand its hardware support and hardening features. Users report successful long-term daily-driver use on Pixel devices, citing privacy benefits over stock Android.
HN Discussion: Longtime users shared experiences, most saying the switch is worthwhile despite minor roughness compared to stock Android.

Enthusiasm emerged for Motorola devices supporting GrapheneOS as a way to de-Google outside Pixel-only regions.
Humiliating IIS servers for fun and jail time
Summary: A bug bounty practitioner walks through attacking IIS servers, covering techniques like tilde enumeration, web.config extraction, NTFS authentication bypass, and WAF evasion. The post explains how IIS’s legacy DOS 8.3 filename convention can leak internal paths and shortnames. Methods include Shodan scanning, Google dorking, Nuclei automation, and using BigQuery to resolve shortnames.
HN Discussion: Some commenters admitted they front honeypots with the IIS splash page to waste attackers’ time. Technical discussion covered 8.3 filename exposure and how it is enabled on the C drive by default on modern Windows. Several HN readers found the tone entertaining despite mixed reactions to the formatting.
Apple is about to make Hide My Email useless
Summary: Apple announced that Sign in with Apple and iCloud+ Hide My Email aliases will now be issued on the @private.icloud.com subdomain instead of @icloud.com. This change makes it trivial for websites to block all iCloud relay aliases by banning the entire subdomain, undermining the privacy protection these aliases provided. The author advises users to pre-generate aliases on @icloud.com while the change has not yet been deployed.
HN Discussion: Several commenters said they would boycott any site that blocks privacy-friendly email aliases entirely. Others pointed out that Hide My Email was already flawed: services cannot send emails back to aliases without pre-registration, breaking shipping notifications and invoices. Alternative approaches were suggested, such as using a personal domain with catch-all forwarding for better control.

The library aims to prevent data races at compile time while delivering high performance for compute workloads. Comparisons to CUDA-Oxide and Burn highlight Rust’s growing ecosystem for GPU compute.
HN Discussion: Commenters asked how cuTile-rs compares to NVIDIA’s existing CUDA-Oxide project in terms of syntax and workflow integration. Mentions of HuggingFace’s Grout project for local LLM inference showed excitement for what cuTile-rs could enable for single-binary high-performance ML deployments. Several replies in the thread were flagged or dead, prompting confusion from readers about moderation.
Frood, an Alpine Initramfs NAS (2024)
Summary: Filippo Valsorda describes Frood, a NAS that runs entirely from an Alpine Linux initramfs with no persistent root filesystem, deployed as a single UKI file. The setup runs from RAM for speed and to avoid SD card wear, with ZFS pools for actual storage and declarative git-based configuration. A recent upgrade moved from a bootloader to a single-file Unified Kernel Image on a 64-core Ampere Altra server.
HN Discussion: Commenters compared Frood to alternatives like ZFSBootMenu with ZFS-root Alpine and systemd’s Diskomator project. Questions arose about why the NAS root would have SSH keys, prompting discussion of secure management patterns. One commenter expressed interest in seeing a similar setup achieved with Nix.
I hacked into the worst e-bike and fixed it [video]
Summary: A maker hacks into a poorly designed e-bike to bypass its app-dependent control system, restoring basic functionality without manufacturer support. The video highlights the right-to-repair problem with smart bikes that require mobile apps for basic operation. The creator used reverse engineering to crack the bike’s control system, reclaiming user ownership of the hardware.
HN Discussion: Commenters expressed outrage that bikes can become partially useless without a companion mobile app, calling it an unacceptable design choice. Advice not to buy e-bikes with custom parts emerged: wear and tear will eventually require replacement parts only available from the maker. One viewer praised the creator’s channel but noted YouTube’s algorithm discourages high-effort content like trail build videos.
Show HN: VoiceDraw – Talk system design out loud, the diagrams draw themselves
Summary: VoiceDraw is a web tool that converts spoken system design descriptions into architecture diagrams using AI and Excalidraw. Users describe their architecture aloud and the tool generates visual diagrams with components and connections. The tool aims to make diagramming accessible, particularly during verbal communication and brainstorming sessions.
HN Discussion: A blind developer noted the generated alt text was not useful for accessibility, providing specific feedback on improving output descriptions. The creator of a similar tool, ShimmerDiagrams, expressed interest in connecting and comparing approaches. Others asked about the technology stack, development team size, and the use of Excalidraw as the rendering foundation.
NetNewsWire Status
Summary: Brent Simmons reports on a year of NetNewsWire development during his retirement, with 2,188 commits including Swift concurrency adoption, Liquid Glass UI, porting parsers from Obj-C to Swift, and significant performance improvements.

Web & Infrastructure
Stop Using JWTs
Summary: A GitHub gist argues against using JSON Web Tokens for browser-based user sessions, citing security concerns and complexity. The author points to known JWT vulnerabilities including algorithm confusion, long-lived tokens, and revocation difficulties. Recommends session-based cookies with server-side storage as a simpler and more secure alternative for web authentication.
HN Discussion: Several commenters qualified the argument: JWTs are problematic for browser sessions but remain useful for service-to-service communication. Defenders noted that JWT lifetime can be limited to 5-15 minutes with a refresh model, mitigating revocation concerns. OAuth2 was cited as a mature, well-audited standard without major security announcements in the past decade.
System Administration
TIL: You can make HTTP requests without curl using Bash /dev/TCP
Summary: A developer demonstrates crafting raw HTTP requests in bash using the /dev/tcp virtual filesystem, useful when curl or wget are absent from stripped-down containers. The technique opens a TCP socket via exec redirection, writes an HTTP/1.1 request with printf, and reads the response with cat. Works for basic health checks and aliveness probes on Docker networks without additional tooling.
HN Discussion: Several commenters reminisced about using telnet to port 80 and SMTP in the late 90s, calling it a foundational hacker skill. One commenter warned that this approach does not properly parse HTTP and should not be used unattended in production. Port knocking usage was mentioned as another practical application of /dev/tcp in bash.
10Gb/s Ethernet: switching to a Broadcom SFP+ module
Summary: A practical blog post details the switch to Broadcom-based SFP+ modules for 10GbE networking, including power consumption and heat considerations. Chinese-manufactured modules with Broadcom chipsets now perform well at under $30, solving earlier overheating issues with older 10GBase-T SFP+ modules. The post weighs fiber versus copper for in-wall cabling now that 10GbE copper runs hot.
HN Discussion: Commenters debated whether fiber is now the right choice for new in-wall cabling given 10GbE copper’s high power draw and heat output. WiFi 7 was presented as a viable alternative for home users at under $200, making wired 10GbE increasingly niche. Unifi’s SFP Wizard was mentioned as a tool that can reprogram SFP modules that lie about their capabilities.

Tracing Watterson’s career from college through the strip’s syndication and eventual end, the article frames his choices as rare in commercial art. Watterson turned down millions in licensing fees to preserve the purity of his creation, ultimately retiring the strip at its peak.
HN Discussion: Readers shared personal connections: one commenter models their parenting after Calvin’s dad, including the black-and-white photo gag. Several admired Watterson’s integrity while acknowledging they would likely take the money in the same situation. A commenter tried repeatedly to get Watterson’s Kenyon College commencement speech onto the HN front page.
A brief tour of the PDP-11, the most influential minicomputer of all time (2022)
Summary: Ars Technica tours the PDP-11, the minicomputer that popularized interactive computing and influenced both Unix and the instruction set used in modern processors. The machine’s clean, symmetric instruction set inspired early Unix development at Bell Labs. Used widely in labs through the 1970s and 80s, it bridged mainframes and microcomputers.
HN Discussion: Commenter kens argued the Datapoint 2200 was more influential, noting its instruction set lives on in x86 and it directly spurred Intel’s microprocessor development. Others recalled the PDP-8 as the true breakthrough for making computing affordable to university departments. Speculation arose about an alternate timeline where the PDP-11 evolved into the desktop PC rather than the IBM PC architecture.
All about the IBM 1130 Computing System
Summary: A comprehensive enthusiast site details the IBM 1130, introduced in 1965 as IBM’s least-expensive computer aimed at engineering and education. The 1130 featured inexpensive disk storage and gave many users their first experience of personal computing. Though technically modest, it retains a devoted following, with emulators, annual meetups, and extensive documentation online.
HN Discussion: A notable trivia point emerged: the 1130’s DMS operating system had a 5-character filename limit, which truncated Chuck Moore’s language name FOURTH to FORTH. Commenters marveled at how many incompatible computer systems IBM had in that era. Some suggested running 1130 simulators on the web to make them more accessible to casual users.
Working in Glass
Summary: Asimov Press publishes a long read on how glass tubing helped democratize chemistry, tracing the practice back to 19th-century chemist Justus Liebig. Liebig’s insight that anyone with glass, a flame, and practice could build their own scientific equipment laid the foundation for the modern laboratory. The essay is part of an upcoming book, “Making the Modern Laboratory.”
HN Discussion: The thread has no comments yet, so only the article content and historical significance are available for discussion.
A Nipkow Disk Mechanical TV Simulator

HN Discussion: One commenter shared a funny broken result image from the simulator. Another wished for an animated working example to better demonstrate the concept. Several expressed curiosity about seeing a real Nipkow disk in action for the first time.
W.H. Auden and James Schuyler in life and literature
Summary: Alan Jacobs examines the literary friendship between W.H. Auden and James Schuyler, focusing on Schuyler’s role as typist, secretary, and companion in the late 1940s. The piece draws on Nathan Kernan’s biography of Schuyler to illuminate an underexplored relationship in literary history. Published in the Hedgehog Review, the essay explores how personal relationships shape artistic output.
HN Discussion: The thread has no comments, so only the article’s literary analysis is available for review.
The Manhoff Archives: Color photos of Stalin-era USSR taken by a US diplomat
Summary: A trove of color photographs taken by US diplomat Major Martin Manhoff in the early 1950s captures Stalin-era Soviet life, including Stalin’s funeral, Moscow street scenes, and travel destinations. The images were hidden for decades and later discovered among a former official’s possessions. The collection provides a rare color window into a period typically seen in black and white, though the subjects predominantly represent the Soviet elite rather than ordinary citizens.
HN Discussion: One commenter noted these photos largely depict the Soviet 1%, while the majority of the population lived without IDs in villages under kolkhoz restrictions. Discussion covered the original source versus a derivative site that may have copied content without attribution. A former Soviet resident provided context on how Moscow was vastly different from the rest of the USSR in terms of infrastructure and quality of life.
Academic & Research
Formal Methods and the Future of Programming
Summary: Jane Street’s Yaron Minsky reverses the firm’s long-standing skepticism toward formal methods, acknowledging their growing value in software reliability. The post traces how lightweight formal methods like OCaml’s type system already deliver significant benefits, while heavier approaches like seL4 remain costly. Minsky argues that improvements in tooling and automation are finally making formal verification practical for more use cases.
HN Discussion: The thread was flagged as a duplicate of another submission of the same article on HN. No substantive discussion beyond the dupe flag is available in this thread.
Demystifying Noise Contrastive Estimation
Summary: A detailed technical explainer covers Noise Contrastive Estimation (NCE), InfoNCE, and partition function estimation, clarifying the differences between Local NCE, Global NCE, and InfoNCE. The post walks through applications in language modeling and contrastive learning, including CLIP, with mathematical derivations and comparisons. NCE methods are computationally efficient alternatives to full softmax when the output vocabulary is very large.

Business & Industry
Has AI already killed self-help nonfiction books?
Summary: Tim Ferriss examines declining sales of how-to and self-help nonfiction, using his own book sales data to argue that AI-generated summaries and advice are eating the market. The post considers whether the genre’s value proposition is collapsing now that anyone can get instant, personalized guidance from language models. Ferriss suggests that the fragmentation of attention across YouTube, TikTok, and podcasts has also diluted the traditional self-help star system.
HN Discussion: Several commenters argued the self-help industry is a self-referential network of product sellers, with Ferriss himself credited as a primary architect. One reader noted AI is accelerating a decline already underway, pointing to YouTube and Substack as earlier disruptors of the book model. A reference was made to technical books going offline as authors shift away from long-form publishing.
Is Meta destroying its engineering organization?
Summary: The Pragmatic Engineer reports that Meta’s engineering culture has been severely disrupted by an AI-focused reorganization that reassigned top engineers from infrastructure teams to data labeling and AI development. The CISO Guy Rosen departed after 13 years, and 30-50% of some infra teams were drafted into the new AI organization. The piece traces Meta’s evolution from move-fast culture to stable infra, and now to an AI obsession that critics say is cannibalizing core engineering capability.
HN Discussion: Former Meta employees noted that acquired orgs like WhatsApp, Instagram, and Reality Labs were better-run than homegrown ones, which had over-hiring and requirement churn. Several commenters warned that AI-induced leadership toxicity could become the new normal across the tech industry, sharing similar experiences at non-Meta companies. Scale AI’s Alexandr Wang was identified by some as playing a significant role in poaching top engineers for data labeling work.

But yak shaving is fun (2019)
Summary: A developer reflects on the joy of yak shaving — the chain of tangential tasks triggered by pursuing a primary goal. The author built a static site generator from scratch after being unsatisfied with existing tools, ultimately finding deep satisfaction in the journey. The essay traces the origin of the term to MIT AI Lab and presents it as a creative rather than wasteful practice.
HN Discussion: Commenters shared their own epic yak-shaving stories, including a 30-year detour from writing a QBasic game to building a hybrid C/Lua game engine. Some noted AI has lowered the cost of yak shaving, making custom tool-building more practical. Others pushed back on yak-shaving-shaming, arguing constraints from existing frameworks can limit engineering creativity.
The Amphibious Villagers of Indonesia
Summary: The Economist’s 1843 magazine features an interactive article about Indonesian communities living on water, adapting to rising sea levels with floating villages. The article is heavily paywalled, with only the title and framing visible without a subscription.
HN Discussion: The only comment visible notes frustration with the aggressive paywall that blocks even viewing the article title. Discussion is limited due to the paywall barrier, so only the general premise is available from the story.
The Magic Roundabout of Seattle Area
Summary: A web game satirizes the notoriously confusing multi-lane roundabout at the 85th Street and I-405 interchange in Kirkland, Washington. Players navigate a roundabout while avoiding collisions and managing lane changes for bonus points. Built with Godot, the game was inspired by online discussions of the real-world intersection’s design.
HN Discussion: A local resident who drives through it daily said the roundabout is still faster than the previous traffic-light configuration, despite initial confusion. Even an experienced roundabout driver admitted to missing their offramp on the first try at this specific Kirkland interchange. One commenter shared a similarly disastrous double-roundabout design from their hometown.
