HN Morning Brief - March 27th, 2026
Good morning! Welcome to today’s Hacker News morning brief covering the top 30 stories from March 27th, 2026. From Tesla computer hacking and a LiteLLM malware deep-dive to prediction market dangers and the death of xv’s creator, here’s what’s trending in tech.
AI & Tech Policy
Schedule tasks on the web
Claude has introduced web-scheduled tasks, allowing users to set up recurring AI agent runs that can browse the web, gather information, and deliver results on a schedule. This moves AI assistants closer to autonomous background agents that can handle routine information gathering, monitoring, and reporting tasks without manual intervention. The feature represents Anthropic’s continued push toward making Claude a persistent, proactive tool rather than just a reactive chatbot.
HN Discussion: Commenters noted that the feature is somewhat restrictive — it doesn’t support screenshots and only allows egress to a few hardcoded domains. Some compared it to Grok’s existing task scheduling feature, which offers more flexibility with 10 concurrent free tasks. There was broader discussion about the trajectory toward fully autonomous software development pipelines where feedback is curated into tickets, converted to PRs by an AI agent, reviewed by another agent, and then deployed automatically — with some arguing this flywheel is already nearly complete.
Show HN: I put an AI agent on a $7/month VPS with IRC as its transport layer
A developer has built a minimalist AI agent system using just two components: a public-facing IRC bot (678KB Zig binary, ~1MB RAM) and a private agent handling email and scheduling over Tailscale via Google’s A2A protocol. The system uses tiered inference with Haiku 4.5 for conversation and Sonnet 4.6 for tool use, with a hard cap of $2/day. The entire setup runs on a cheap VPS, demonstrating that capable AI agents don’t require massive infrastructure or expensive cloud services.
HN Discussion: Several commenters were impressed by the resource efficiency and the creative use of IRC as a transport layer. Others noted that cheaper models from OpenRouter (like MiniMax M2.7 or Kimi K2.5) could match Haiku’s performance for significantly less money. One commenter who tried the bot found the personality “dismissive and tough” but appreciated the overall architecture. The IRC transport choice sparked discussion about using chat rooms as prompt/context switching mechanisms for coding agents.
Agent-to-agent pair programming
A new workflow demonstrates using two AI coding agents — Claude for generation and Codex for review — in a pair programming setup where one agent creates code and the other audits it. The approach leverages the complementary strengths of different models, using Claude’s creativity for implementation and Codex’s precision for catching bugs and inconsistencies. This multi-agent workflow is emerging as a powerful pattern for improving code quality beyond what any single model can achieve alone.
HN Discussion: Users shared their own similar experiences, with one noting that “it’s very rare Claude has fully completed the task successfully and Codex doesn’t find issues.” Others expressed a need for more scientific validation of multi-agent approaches rather than relying on vibes alone. Some preferred using Claude for generation and Codex specifically for “bull-headed, accurate complaining and audit,” finding it most effective in that adversarial role.
Chroma Context-1: Training a Self-Editing Search Agent
Chroma has published research on Context-1, a search agent that can self-edit its own retrieval context to improve performance over time. The system learns to prune and restructure its search context through iterative refinement, eventually reaching a point where it reconstructs what it needs automatically rather than relying on explicit filtering. This represents an interesting direction in agentic RAG systems where the agent learns to manage its own information retrieval rather than relying on fixed pipelines.
HN Discussion: One commenter raised a notable controversy — another research group claimed Chroma republished their December research without attribution four months later. Technical discussion focused on whether pruning individual documents or tombstoning entire trajectories is the better approach, and on the observation that once context gets compressed enough, the system begins to feel less like search-plus-filtering and more like a continuously self-reforming process. Others questioned why not adopt an approach similar to Kimi’s tombstoning method.
From 0% to 36% on Day 1 of ARC-AGI-3
Symbolica claims to have achieved 36% on the ARC-AGI-3 public benchmark set using their custom inference harness, though this doesn’t qualify for the official leaderboard since it uses a non-standard evaluation setup. The public set consists of 25 problems intended for development and testing, while the actual evaluation uses 110 private problems described as “materially easier.” The results highlight the power of inference scaffolding and the ongoing debate about whether benchmark gaming is meaningful progress toward general intelligence.
HN Discussion: Critics were quick to point out that testing on the development set rather than the private evaluation set makes the headline misleading, with one commenter calling it “a lie.” Others invoked Goodhart’s Law, noting that observed statistical regularities collapse when pressure is placed upon them for control purposes. A researcher argued that scaffolding can do a lot across all domains but questioned whether ARC-AGI proves anything useful at all: “It is not a useful task at all in the wild. It is just a game; a strange and confusing one.”
$500 GPU outperforms Claude Sonnet on coding benchmarks
The ATLAS project demonstrates that a $500 consumer GPU running open-source models can outperform Claude Sonnet on certain coding benchmarks using a custom “Geometric Lens routing” pipeline with best-of-3 sampling and automated repair. The approach uses local inference with only electricity costs (~$0.004 per benchmark run) compared to Claude’s API pricing. However, commenters noted that DeepSeek V3.2 achieves even higher scores (86.2% single-shot vs 74.6% best-of-3) at roughly half the cost.
HN Discussion: The discussion quickly turned skeptical, with several commenters noting that you can make models pass benchmarks but they may not be practically useful. Others pointed out that cheaper API models like DeepSeek V3.2 already beat this local approach on both accuracy and cost. A practitioner warned that MiniMax and Kimi models show “palpable” degradation on real-world tasks despite appearing competitive on benchmarks: “Sadly, you do get what you pay for right now.” The broader question of whether open-source or local LLMs will eventually kill big AI providers was debated, with uncertainty remaining about coding and image generation capabilities.
HyperAgents: Self-referential self-improving agents
Meta Research has published a paper on HyperAgents — AI systems that can modify their own scaffolding to achieve self-improvement without changing the underlying model weights. The key insight is that since both evaluation and self-modification are coding tasks, gains in coding ability can translate into gains in self-improvement ability. The system experiments with editing parent selection strategies and redisovers heuristics like UCB and softmax, though it doesn’t yet beat handcrafted versions. The full optimization runs cost approximately 88M+ tokens.
HN Discussion: A researcher working in the area expressed frustration with the hype, noting that what they’re actually doing is “trying to modify the scaffolding around a frozen FM until they get something better” — not the runaway self-improvement that marketing implies. They acknowledged it’s a legitimate extension of prior work but said people need to temper expectations. Others found the compositional improvement pattern fascinating, noting that individual components that aren’t precise can become better through composition, much like how e2e coding improved by adding linter, compiler, and static analysis stages.
Security & Privacy
My minute-by-minute response to the LiteLLM malware attack
A detailed first-person account from the developer who discovered and reported the compromised LiteLLM packages (v1.82.7 and 1.82.8 on PyPI) reveals how an ML engineer used Claude Code to help navigate the security incident in real time. The transcript shows the developer working through the discovery, investigation, and responsible disclosure process with AI assistance, ultimately helping to contain the attack. The compromised packages were designed to steal API keys and environment variables from unsuspecting users.
HN Discussion: Simon Willison noted this was the first time his Claude Code transcripts tool was used to construct data embedded in a blog post. Commenters raised concerns about having LLM agents handle security-sensitive tasks like downloading potentially malicious files from PyPI, even in Docker containers: “we should be careful with things we hand over to the text prediction machines.” There were calls for package registries to expose a firehose for real-time security analysis, and speculation that without the 11k process fork bomb, the attack might have gone unnoticed for much longer.
Anthropic Subprocessor Changes
Anthropic has updated its list of subprocessors, notably adding Microsoft Azure as a provider of cloud infrastructure for all Anthropic products worldwide. The change is significant for enterprise customers with data residency requirements, as it means Azure now handles Anthropic’s infrastructure alongside existing providers. The list distinguishes between subprocessors that handle customer data versus operational/business data, with the former having more significant compliance implications under GDPR, HIPAA, and similar frameworks.
HN Discussion: One commenter noted the broader pattern: “With respect to my private data, it seems all roads eventually lead to California.” Others discussed the distinction between customer data and operational data subprocessors, noting that the 30-day notification window for customer data additions is fairly standard for enterprise SaaS. The proactive publication of the list was seen as a positive signal, though some questioned why Anthropic linked to only one FedRAMP service provider despite multiple options existing.
Business & Industry
Apple discontinues the Mac Pro
Apple has officially discontinued the Mac Pro, marking the end of an era for its most expandable desktop workstation. The move reflects the reality that Apple’s M-series chips have made internal PCIe expansion largely unnecessary for most pro workflows. Thunderbolt and USB-C now handle external connectivity that previously required internal slots, and the M2 Ultra Mac Pro with its mostly-empty chassis was widely seen as a box of air. Apple is expected to focus on the Mac Studio form factor for high-performance computing needs.
HN Discussion: Many commenters saw this as inevitable and overdue. One noted that specialized equipment like audio interfaces and oscilloscopes now work over USB-C, eliminating the need for PCIe slots. Others lamented that Apple missed an opportunity to compete with Nvidia in AI training by not building multi-GPU workstations: “They had the infrastructure and custom SoCs and everything. What a waste.” Several pointed out that Apple is perfectly positioned for the inference era thanks to unified memory, with no DIY build able to match the M-series for high-memory-throughput inference at comparable prices. The 2019 Mac Pro was viewed as primarily a signal that Apple still cared about the Mac, a message no longer needed given today’s strong Mac lineup.
We rewrote JSONata with AI in a day, saved $500k/year
Reco.ai claims to have saved $500,000 per year by using AI to rewrite their JSONata expression evaluator from JavaScript to Go, eliminating the need to run a fleet of Node.js pods communicating over RPC. The original architecture — calling jsonata-js from Go services over the network — was costing approximately $300K/year in compute. They ported the test suite to Go and iterated with Claude until all tests passed, reportedly spending only $400 on AI tokens for the entire rewrite.
HN Discussion: The post drew significant skepticism. One commenter noted it was “baffling” that a critical business component costing $300K/year was left in such a questionable architecture for so long, especially when the rewrite only took $400 of Claude tokens — suggesting the codebase wasn’t that large and could have been ported by hand. Others pointed out that existing Go implementations of JSONata already existed and that the benchmarks were misleading (measuring within-app rather than library-level performance). The broader criticism was that the real achievement was fixing a bad technology choice, not the AI aspect: “These blog articles are supposed to be a showcase of engineering expertise, but bragging about having AI vibecode a replacement for a critical part of your system that was questionably designed raises a lot of questions.”
We haven’t seen the worst of what gambling and prediction markets will do
Derek Thompson argues that prediction markets and gambling apps like Polymarket and Kalshi are creating increasingly dangerous incentives, including a recent case where an Israeli Air Force reservist allegedly used classified information to bet $162,663 on the timing of strikes against Iran. The article explores how the gamification of real-world events creates perverse incentives for information leaks, market manipulation, and the commodification of sensitive intelligence. With combined trading volumes around $50 billion, these platforms are becoming significant forces that could distort decision-making at the highest levels.
HN Discussion: One commenter pointed out that calling trading volume “revenue” was misleading — Kalshi’s actual fee revenue was about $263 million, not $50 billion. The breaking news about the Israeli reservist’s indictment dominated discussion, with several noting the national security implications of prediction markets incentivizing insider trading on military operations. Suggestions for mitigation included limiting bet sizes to $20 to reduce damage while preserving fun, and promoting play-money prediction markets which “provide a useful service to understand what is going on in the world” without creating perverse incentives. One defender argued that markets ultimately punish manipulation: “If a billionaire tries to pump a ‘bad’ policy, every smart trader sees the arbitrage and bets against them.”
Tech Tools & Projects
Dobase – Your workspace, your server
Dobase offers a self-hosted workspace combining email, calendar, drive, and other productivity tools into a single application. The platform aims to provide a sovereign alternative to big tech workspace suites, giving users control over their data. However, the non-compete clause in its license restricts users from offering it as a SaaS product, drawing criticism for being “almost-but-not-quite-FOSS.”
HN Discussion: The licensing model was the main point of contention, with one commenter flatly rejecting it: “These ‘almost-but-not-quite-FOSS’ licenses are a blight.” Others questioned why a full app was needed when a browser with pinned tabs could achieve the same result. One user defended the concept of sovereign systems, arguing that good FOSS commodity options could eventually create hosting infrastructure similar to WordPress. The broader discussion touched on the tradeoffs of all-in-one workspace apps versus specialized tools, with some noting that combining everything into one UI often makes navigation more cumbersome rather than less.
Whistler: Live eBPF Programming from the Common Lisp REPL
Whistler is a project that enables live eBPF (Extended Berkeley Packet Filter) programming directly from a Common Lisp REPL, allowing systems programmers to write, test, and modify kernel-level tracing and monitoring tools interactively. This is an unusual combination — eBPF is typically programmed in C with specialized tooling, while Common Lisp is known for its interactive development capabilities. The project demonstrates how Lisp’s live-coding philosophy can be applied to systems programming, offering a REPL-driven development experience for kernel tracing.
HN Discussion: The project was praised for its creativity and technical ambition. One commenter admitted to being “in danger of being nerd sniped” by the concept. However, there was mild criticism of the blog’s AI-generated “why this matters” section, which gave it “a lingering vibe of slop” — a growing complaint about AI-generated padding in otherwise interesting technical posts.
Generators in Lone Lisp
A deep dive into implementing generator functions (semi-coroutines) in Lone Lisp, exploring the theoretical underpinnings of continuation types. The article classifies different continuation styles along multiple axes: asymmetric vs symmetric, stackful vs stackless, delimited vs undelimited, and reentrant vs non-reentrant. The resulting generators are asymmetric, stackful, delimited, non-reentrant continuations — a specific combination that enables cooperative multitasking patterns familiar from Python and JavaScript generators.
HN Discussion: One commenter provided an excellent Stack Overflow reference that classifies continuations along even more dimensions: multi-prompt vs single-prompt, and clonable vs non-clonable. The discussion remained focused on the theoretical computer science aspects, with appreciation for the clear explanation of how generator mechanics relate to broader continuation theory.
Running Tesla Model 3’s computer on my desk using parts from crashed cars
A security researcher has managed to run a Tesla Model 3’s onboard computer on their desk using salvaged parts from crashed vehicles, complete with a functional display output via LVDS. The project required sourcing the car’s main computer unit, power supply components, and display cabling from written-off Teslas. Tesla’s bug bounty program offers a “Root access program” where researchers who find rooting vulnerabilities receive a permanent SSH certificate for their own car, providing a path to deeper exploration.
HN Discussion: Commenters were impressed by the hardware hacking, with several sharing their own Tesla modification experiences including towing brake controller installations. The bug bounty program was compared to Apple’s Security Research Device Program as a good balance between security and research access. One commenter noted you can run Tesla’s QtCar UI application on QEMU if you have the firmware. The discussion also touched on the broader culture of car hacking and whether automakers should provide more open access to the computers in vehicles their customers own.
HandyMKV for MakeMKV and HandBrake Automation
HandyMKV is an automation tool that streamlines the workflow between MakeMKV (disc ripping) and HandBrake (video transcoding), removing the manual steps typically required when digitising physical media. The tool chains the two applications together so users can insert a disc, have it automatically ripped and transcoded to their preferred format. It represents the kind of personal automation that many users build for themselves but rarely share publicly.
HN Discussion: One commenter dismissed HandBrake as “the best if you want to ruin all of your DVD encodes,” while another shared their own Claude-built alternative that adds IMDB API lookups and LLM-based track selection. The post highlighted a broader trend of using AI coding assistants to quickly build bespoke CLI tools for personal workflows — “a really fun time to be building small bespoke tools for yourself.”
Show HN: Fio: 3D World editor/game engine – inspired by Radiant and Hammer
Fio is a compact, lightweight 3D world editor and game engine inspired by classic level editing tools like Radiant (used for Quake III) and Hammer (Valve’s Source engine). Built with a focus on running on modest hardware (targeting Snapdragon 8CX, OpenGL 3.3), it features a liminal brush-based CSG editor with real-time stencil shadow lighting without requiring pre-baked compilation. The project aims to capture the feel of classic BSP-based level editors while running on modern, lower-power hardware.
HN Discussion: The project sparked strong nostalgia for the era of Q3 map-making and custom game servers, with one commenter recalling getting “lost in the various Radiant variants as a teen building DM and CTF maps.” Others asked about BSP draw optimization and whether anything had been made with the tool yet. The project represents a growing interest in retro-inspired game development tools that prioritize simplicity and accessibility.
Web & Infrastructure
DOOM Over DNS
A developer has figured out how to store and load the entire DOOM game using DNS TXT records, leveraging Cloudflare’s free global DNS infrastructure as a content delivery network. The game is encoded into DNS records and served from the edge, with Cloudflare caching handling the distribution. While the title suggests “running” DOOM over DNS, the technique actually uses DNS purely as a storage and distribution layer rather than for computation — a distinction that several commenters were quick to clarify.
HN Discussion: One commenter provided a corrective title: “Loading Doom entirely from DNS records” rather than “running” it over DNS. Others questioned the ethics of abusing free infrastructure, comparing it to “eating for free by going to McDonald’s and eating a pint of ketchup without ordering anything.” The discussion also touched on Dan Kaminsky’s classic Ozyman DNS tool for tunneling SSH over DNS, and someone jokingly suggested “DOOM over pingfs” as the next logical step.
OpenTelemetry profiles enters public alpha
OpenTelemetry has entered public alpha for its continuous profiling specification, bringing standardized, always-on performance profiling to the observability ecosystem. The profiles feature aims to provide low-overhead performance profiling in production, allowing teams to capture detailed performance data without the traditional tradeoffs of sampling profilers. This is a significant milestone for the project, which has been working toward making profiling a first-class telemetry signal alongside traces, metrics, and logs.
HN Discussion: Users noted that OpenTelemetry still has rough edges and isn’t yet the one-stop shop for telemetry that many want, with particular gaps in Sentry-style exception capturing. Recent metric name changes broke many existing dashboards. Several compared it to Grafana Pyroscope, which is already mature for continuous profiling. One skeptic questioned whether anything from the OTel community could truly meet “low-overhead” expectations, though Elixir users reported positive experiences with the profiling implementation. The alpha represents meaningful progress toward unified observability.
Show HN: Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3
Turbolite is an experimental SQLite VFS (Virtual File System) written in Rust that can serve cold queries directly from S3 with sub-second performance by introspecting SQLite’s B-tree structure and storing related pages together in compressed page groups. Rather than doing naive page-at-a-time reads from a raw SQLite file, it maintains a manifest tracking where every page lives and uses seekable zstd frames with S3 range GETs. Benchmarks show sub-100ms cold point lookups, sub-200ms cold 5-join profile queries, and sub-600ms scans from an empty cache with a 1.5GB database on EC2 + S3 Express.
HN Discussion: The author provided extensive technical details, explaining that the key insight was that “nearby in the file is not the same thing as relevant to the query” — which pushed them toward B-tree-aware grouping. Other developers working in similar spaces (sqlite-prefetch, Graft) engaged deeply with the architecture, discussing tradeoffs between this approach and replication-first designs like Litestream. One commenter proposed using Turbolite as a bridge during deployments to achieve zero-downtime with single-writer SQLite setups. The discussion highlighted the growing ecosystem of SQLite-over-cloud experiments targeting database-per-tenant architectures.
Colibri – chat platform built on the AT Protocol for communities big and small
Colibri is a new chat platform built on Bluesky’s AT Protocol, aiming to provide a community-oriented messaging experience that benefits from the decentralized social graph. The platform allows users to create and join community spaces using their Bluesky credentials, leveraging AT Protocol’s open architecture for identity and social connections. However, the architectural choice of building a chat platform on a fundamentally public protocol raises significant privacy concerns.
HN Discussion: Privacy was the dominant concern, with one commenter calling the architectural decision “not only a liability but bordering negligence” since AT Protocol makes all communications completely public to the internet by design. This is problematic for community chat where users expect private conversations: “You can imagine how big of an issue this is when you try to do it in a trusted community model. Add on that Discord is used by kids who likely don’t know this.” The lack of end-to-end encryption was cited as a nonstarter for most use cases, with multiple commenters saying they’d only consider it with E2EE support. Others questioned the broad permissions requested for Bluesky accounts.
Swift 6.3
Swift 6.3 has been released with several notable improvements including the first official release of the Swift SDK for Android, bringing Apple’s language to Google’s mobile platform. The release also includes improvements to embedded Swift for resource-constrained environments, and continued refinement of the language’s concurrency model. However, users noted the continued absence of meaningful compilation speed improvements, with Swift remaining slower to compile than Rust — a persistent pain point that hampers developer experience.
HN Discussion: The release prompted reflection on Swift’s trajectory. One commenter argued that around 2015-2017, Swift “could have easily dethroned Python” given its simplicity, speed, and C/C++ interop, but Apple failed to build the community beyond its own ecosystem. Compilation times were the most criticized aspect, with one developer who recently ported xv6-riscv to multiple languages noting that “the compilation times are SO bad” that they shifted focus to the Nim port. Another praised embedded Swift improvements as making it “one of the most enjoyable/productive languages to work on the OS” while acknowledging the compilation speed problem. The Android SDK release was noted as a significant step toward Swift’s goal of being usable at every layer of the software stack.
History & Science
Why so many control rooms were seafoam green (2025)
A fascinating exploration of why mid-century control rooms — from NASA’s Mission Control to industrial plants and military facilities — were overwhelmingly painted in seafoam green. Beyond stylistic choices, the color served practical purposes related to visual fatigue reduction during long shifts monitoring instruments. The piece also notes that zinc chromate and zinc phosphate corrosion-protective coatings naturally produced colors in this range, making seafoam green both a functional and chemically convenient choice for industrial environments.
HN Discussion: Commenters drew connections to similar color choices in other contexts, including “Go Away Green” used by Disney to make uninteresting structures blend into backgrounds, and turquoise cockpit colors in aviation. Many expressed nostalgia for a time when institutional buildings had actual color rather than the prevailing “everything must be gray/beige” aesthetic of the last 30 years: “I remember the wall colors in banks, schools, doctor’s offices, McDonalds in the 1970s and they seemed so wonderful. All these things got a coat of white paint sometime in the 2000s and look the same as everywhere else now.”
John Bradley, author of xv, has died
John Bradley, creator of the iconic xv image viewer for Unix/X11, has passed away. xv was a groundbreaking image manipulation tool in the 1990s, featuring capabilities that in some cases still haven’t been replicated — including its remarkable color editor that could remap arbitrary regions of color space. Bradley was remembered as a generous person who licensed his software commercially but remained accessible and agreeable to collaboration, including one arrangement where a developer sold an xv scanning extension and split the revenue with him.
HN Discussion: The comments were filled with warm personal memories. One commenter recalled using xv’s color editor to turn Elmo green and purple to entertain their toddler daughter. Another described learning GUI programming by studying xv’s source code, printing it out to study during a 1994 family holiday. Users noted that xv is still actively used — one commenter still uses it on headless AWS instances via X11 forwarding, and another praised features they “still can’t find elsewhere.” The post served as a touching tribute to Bradley’s impact on generations of Linux users and developers.
Academic & Research
The Legibility of Serif and Sans Serif Typefaces (2022)
A comprehensive academic study spanning nearly 160 pages concludes that there is no meaningful difference in legibility between serif and sans serif typefaces, whether reading from paper or screens. The meta-analysis examined decades of research on the topic and found that “the overwhelming thrust of the available evidence is that there is no difference.” The finding gives designers freedom to choose typefaces based on aesthetic and branding preferences without worrying about readability impacts.
HN Discussion: One commenter provided a succinct summary: typographers and software designers should feel free to use both serif and sans serif typefaces, even when legibility is a key criterion. The discussion was relatively brief, with the comprehensive nature of the study leaving little room for debate.
CERN to host a new phase of Open Research Europe
CERN will host Europe’s flagship open-access publishing platform, Open Research Europe (ORE), which operates under a Diamond Open Access model — free for both readers and authors with no Article Processing Charges. The platform aims to provide an alternative to for-profit publishers like Elsevier, where researchers do peer review for free while their institutions pay for access. The move represents a significant step toward publicly funded, community-controlled academic publishing infrastructure.
HN Discussion: Commenters welcomed the initiative but noted challenges ahead. Publication reputation takes years to build, and publishing in prestigious journals like Nature remains “career decisive” for researchers. The CS community was cited as having a better model where top publications are attached to non-profit conferences with zero fees. Concerns were raised about geographic limitations, as authorship eligibility is restricted to researchers from consortium member countries. Several argued that removing for-profit stakeholders and having researchers handle their own typesetting and promotion could dramatically reduce costs.
System Administration
Using FireWire on a Raspberry Pi
Jeff Geerling has successfully connected FireWire (IEEE 1394) devices to a Raspberry Pi using a PCIe-to-FireWire adapter card, keeping the legacy protocol alive on modern hardware. The project demonstrates that the nearly 30-year-old standard still works for digitising old media like VHS tapes and MiniDV recordings, though Linux support may be dropped around 2029. The setup enables practical uses like digitising deteriorating analog media and connecting legacy audio equipment to modern single-board computers.
HN Discussion: Several commenters shared their own FireWire setups for archiving old media, with one noting that dvgrab on Linux can automatically split noncontinuous clips into separate files for unattended digitising. A studio owner expressed interest in replacing an aging iMac with a Raspberry Pi for their FireWire audio interfaces (Presonus rack units with 10 I/Os), though they questioned whether the Pi could handle 40 channels of audio simultaneously given SD card write speed limitations. The looming 2029 Linux kernel deprecation was noted as a concern for anyone with legacy FireWire investments.

Chicago artist creates tourism posters for city’s neighborhoods
A Chicago artist has created a series of tourism posters celebrating the city’s diverse neighborhoods, from famous areas to lesser-known enclaves. The posters bring a vintage travel poster aesthetic to local Chicago communities, turning ordinary neighborhoods into destinations worth visiting. The project has become popular enough locally to be described as “kind of a cliché,” according to one commenter, though the artist’s genuine surprise and delight at the reception was widely appreciated.
HN Discussion: One commenter dryly noted that “no matter how convincing the poster is, I think you’ll be disappointed if you plan a trip to visit scenic Galewood.” The discussion also veered into Chicago squirrel-related art (the SquirrelTruth Kickstarter that posted CTA signs warning about “7 squirrels wearing a human suit”), and one commenter shared that the post made them more excited about their upcoming move from San Francisco to Chicago.
Chopping my brain into bits – turning my brain into a 3D model on the web
A developer has created an interactive 3D web model of their own brain using MRI scan data, making it publicly viewable online. The project uses a free and fully documented pipeline to convert medical imaging data into a three-dimensional visualization that can be explored in a browser. It’s both a technical achievement in medical data visualization and a philosophical statement about the intersection of personal identity and digital technology.
HN Discussion: One commenter saw potential for personal neuroscience experiments: since the pipeline is free and documented, someone could do an n=1 study — baseline scan, learn Mandarin for a year, rescan, and see if their hippocampus actually changed. They wondered why nobody in the biohacking community has tried this given that “people are already dropping $300 on CGMs.” Another simply said: “It is in no uncertain terms an honor to get to look at the shape of the brain that made something like this!”
That’s all for today’s morning brief. See you this evening for another roundup. If you enjoyed this, share it with a friend who might appreciate starting their day with a curated look at Hacker News.
