2.Navier-Stokes – Tristan Buckmaster [pdf](cims.nyu.edu)
1996 points by procedurecall 2 days ago | 811 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • Outrage at OpenAI for allegedly stealing research and threatening academics
  • Skepticism that AI companies honor their no-training-on-data promises
  • This will cause institutions to distrust and restrict AI tool usage
  • Defense of OpenAI or noting the accused has denied allegations
  • ~Questioning credit attribution since original ideas came from other mathematicians
3.How to build a printer(nishantjosh.dev)
432 points by cat-whisperer 1 day ago | 103 comments | permalink
tl;dr: The author turned an Xteink X3 e-ink reader into an AirPrint-compatible printer by implementing IPP over HTTP and advertising it via Bonjour/mDNS. To handle full-page images on a device with only ~7KB of free RAM after Wi-Fi, they streamed incoming pages through a row-by-row decode/scale/dither pipeline directly into the display's existing framebuffer, avoiding a second image buffer. Printed pages are saved as BMPs to the SD card, which serves as the "output tray."
HN Discussion:
  • ~Technical suggestion to use exact screen dimensions in IPP to avoid scaling
  • Enthusiasm for the clever hack of emulating a printer for e-ink displays
  • Excitement about novel use cases for open e-ink platforms like photo frames or secondary displays
  • Suggestion of alternative formats or approaches like DjVu or PostScript interpretation
  • ~Disappointment that the article isn't about building an actual physical printer
4.AlphaGenome Atlas: a high-resolution map of human DNA(blog.google)
591 points by utiiiD 2 days ago | 130 comments | permalink
tl;dr: Google DeepMind released AlphaGenome Atlas, a 1-petabyte database containing pre-computed predictions for the regulatory impact of all ~9 billion possible single-nucleotide variants in the human genome, generated by their AlphaGenome AI model. It introduces the AlphaGenome Variant Impact (AVI) score to rank variants across coding and non-coding regions, and has already helped researchers identify a causal DNM1 splice variant in rare disease work and uncover 22% more non-coding associations in UK Biobank BMI data. Access is via a no-code web portal.
HN Discussion:
  • Enthusiasm for the ambitious 'compute them all' approach and DeepMind's execution
  • Skepticism that AlphaGenome offers real improvements over existing SOTA models like Borzoi
  • Questioning whether this is genuinely new information or just repackaging existing API data
  • ~Concerns about missing coverage of promoter sequences and regulatory concentration dynamics
  • Practical usability feedback and questions about applying it to personal genomes
5.Mercury 2.5(inceptionlabs.ai)
245 points by Topfi 1 day ago | 52 comments | permalink
tl;dr: Inception has released Mercury 2.5, claimed to be the largest diffusion-based LLM ever trained, delivering 1,107 tokens/sec on NVIDIA GPUs with a 260K context window and pricing at $0.20/$0.75 per million input/output tokens (80% off at launch). The model reportedly matches cost-optimized frontier models like GPT-5.6 Luna, Gemini 3.5 Flash-Lite, and Claude Haiku 4.5, with production users citing sub-200ms latencies for voice agents and 82% latency reductions for coding context compaction. Inception also previewed Mercury Voice (sub-170ms TTFT) and Mercury Router for model routing.
HN Discussion:
  • Model performs well for creative writing and speed-critical tasks like reranking
  • Disappointment that the model is not open weights despite mentioning widely available GPUs
  • ~Overeager IP-protection classifier causes errors when probing the model
  • ~Model is usable but nowhere near frontier, though compelling on price/latency
  • Enthusiasm and encouragement for pursuing diffusion-based LLM direction
6.DaVinci Resolve 21.1(blackmagicdesign.com)
436 points by tosh 2 days ago | 199 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • ~MCP/AI integration is welcome but limited by Studio-only paywall and missing API features
  • Resolve is a rock-solid, powerful editor that keeps improving with free upgrades
  • Linux version has frustrating limitations (no h264/AAC, no VST3, no JACK, install difficulty)
  • AI assistant integration helps navigate Resolve's overwhelming complexity for users
  • Users are exploring Resolve for adjacent use cases like photo editing or programmatic workflows
7.I-have-ADHD: A skill to stop coding agents from burying the answer(github.com)
527 points by domhudson 2 days ago | 364 comments | permalink
tl;dr: A plugin/skill for coding assistants (Claude Code) that enforces terse, action-first responses: lead with the next command, number steps, cap lists at 5, and drop preamble, recap, and pleasantries like "Great question!" or "Hope this helps!". Defined by 10 rules in a SKILL.md file, it's installable via the Claude plugin marketplace and forkable for customization. Loosely inspired by The Adult ADHD Tool Kit, but tuned for LLM output style rather than human productivity.
HN Discussion:
  • Frustration with Claude's verbosity confirms the problem the skill addresses
  • Skills like this don't work reliably; Claude reverts to verbosity after a few turns
  • The repo is bloated with 60+ files for what is essentially a 140-line prompt
  • ~Output styles or lint scripts work better than skills for controlling Claude's output
  • Concerns about the install method being unsafe by telling LLMs to fetch from GitHub
8.Tao: Open math problems being non-renewably mined by AI(mathstodon.xyz)
469 points by _alternator_ 1 day ago | 403 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • Agrees that AI extraction damages the ecosystem needed for future mathematical progress and understanding
  • Questions whether merely solving problems actually precludes human knowledge advancement
  • Disputes the framing by noting math has always been highly competitive throughout history
  • ~Reframes the issue as an opportunity: AI's next frontier should be asking good questions
  • Skeptical that open math problems are actually a finite/exhaustible resource
9.On the Navier–Stokes Millennium Prize Problem(openai.com)
1327 points by tedsanders 1 day ago | 1108 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • Impressed by the capability leap of OpenAI's internal model in mathematics
  • ~The achievement is overshadowed by drama and questionable behavior by OpenAI researchers
  • Concerned about ethical issues like potential data spying on other researchers
  • LLMs have clearly surpassed human mathematicians at the frontier of discovery
  • Converting landmark math problems into viral benchmark posts wastes their scientific value
10.Benchmarking Qwen3.8 27B quantizations: 4-bit holds up, 1-bit collapses(quesma.com)
283 points by stared 2 days ago | 131 comments | permalink
tl;dr: Benchmarking Qwen3.8 27B quantizations on GPQA Diamond, IFBench, and Terminal-Bench 2.1 shows that 4-bit Q4_K_M (17GB) matches full BF16 performance and fits on a 24GB GPU, while 2-bit degrades modestly but remains usable. 1-bit quantizations collapse to random-chance performance, with longer reasoning making results worse as models exhaust token budgets. Takeaway: pick the largest quant that fits your VRAM plus context—Q4_K_M is the sweet spot, and quantization shouldn't be feared.
HN Discussion:
  • Confidence intervals are misused in the article and don't reflect run-to-run variation
  • Requests extending benchmarks to KV cache quantization and other missing quant levels like Q3
  • Personal experience confirms low quants remain usable, supporting the article's conclusion
  • ~End-to-end quality measurement is valuable but methodology around KL-divergence datasets needs more nuance
  • Real-world coding tasks show quality cliffs at higher quants (Q5/Q6) than article suggests
11.We built our house for LAN parties (2024)(lanparty.house)
586 points by fittingopposite 4 days ago | 364 comments | permalink
tl;dr: Cloudflare engineer Kenton Varda and Jade Wang built a custom house in Austin featuring 12 wall-mounted PCs in the basement plus 6 more in the office, all fold-away, with 20 identical netbooted machines (i5-13600KF, RTX 4070, 32GB RAM) running from a shared disk image in a dedicated server room with its own A/C. Additional features include DDR pads in the floor, extensive Cat6 wiring with UniFi networking, fiber-optic DisplayPort/USB runs up to 100ft to the stations, cat doors throughout, and a roof deck. It's a follow-up to Varda's 2011 Palo Alto LAN house, scaled up for family life.
HN Discussion:
  • Wholesome admiration for the builders enjoying life and their friend group
  • Nostalgia for LAN parties and suggestions for modern equivalents
  • ~Constructive suggestions for improvement (external blinds for energy, decor for coziness)
  • Feels the showcase resembles wealth-bragging like MTV Cribs
  • Curious about technical details like long-distance HDMI/USB cabling
12.Copyright does more harm than good and should be abolished(grapheneos.social)
302 points by Cider9986 1 day ago | 299 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • ~Copyright terms are far too long and should be drastically shortened rather than abolished
  • Copyright in its current form does more harm than good and should be reformed or abolished
  • This is big tech propaganda aimed at avoiding licensing fees for training data
  • Without copyright, creators cannot justify investment or protect their work from immediate copying
  • Copyright is essential to protect Free Software and copyleft licenses
13.ChatGPT Images 2.5(openai.com)
375 points by vertigoruntime 1 day ago | 442 comments | permalink
tl;dr: Summary not available
HN Discussion:
  • Praises significant speed improvements and technical benchmarks of the new model
  • Questions the quality and choice of showcase examples, noting flaws and poor use cases
  • Enjoys creative personal uses like visualizing scenes from books
  • Concerned about enabling fakery, deception, and misrepresentation in personal and commercial contexts
  • Critiques that examples displace human creativity and real artists rather than solving real needs
14.Kimi K3 (2.8T) at 1 token/s on a MacBook Pro, streamed from four SSDs(github.com)
276 points by Argonautlabs 1 day ago | 152 comments | permalink
tl;dr: A fork of the Deltafin engine runs the full unpruned 2.8T-parameter Kimi K3 MoE model on an M5 Max MacBook Pro (128GB) at ~1 token/sec decode, streaming 1.45TB of expert weights from four SSDs. Scaling tests show the slowest drive per layer bottlenecks throughput (one drive gets 52%, three drives 90% of four-drive speed), and prefill is painfully slow—~6.3 minutes to first token on a 512-token prompt—because each layer's experts are re-read 8 times, a known but unfixed bug.
HN Discussion:
  • Impractically slow performance makes this more novelty than usable tool
  • Prefill/prompt loading bottleneck matters more than decode speed reported
  • Modular/sparse model architectures could avoid needing full weights loaded
  • Hardware limitations (Apple RAM, SSD speed) are the real constraint here
  • Achievement is impressive as a starting point for local large-model inference
15.Show HN: Copperhead – Cursor for circuit boards(copperhead.sh)
242 points by animeshchouhan 2 days ago | 113 comments | permalink
tl;dr: Copperhead is an open-source AI agent that designs and verifies KiCad PCBs through an eight-stage pipeline (brief → spec → architecture → BOM → schematic → layout → gerbers → firmware → dev plan), gating each stage on validated artifacts and clean ERC/DRC checks. It makes surgical edits to KiCad s-expression files rather than regenerating them, refuses to run on dirty git trees or violate documented constraints, and aims to prevent the design drift that causes costly board respins. The CLI is free (Apache-2.0, BYO model key); hosted cloud, team, and enterprise tiers start at $49/user/month.
HN Discussion:
  • KiCad is the wrong foundation for AI-driven EDA; alternatives like tscircuit are better suited
  • Notes competing/similar products already exist in this heating-up space
  • Laments that AI is invading electronics, threatening quality-focused hobbyist culture
  • Generic coding agents with Skidl already work well, questioning need for specialized tool
  • Criticizes AI-generated marketing copy and questions value of hosted/paid tiers
16.Getting your hands dirty is good for you(bbc.com)
247 points by HatchedLake721 2 days ago | 209 comments | permalink
tl;dr: Finnish research suggests that direct skin contact with soil, plants, and moss significantly increases microbial diversity on the skin, which supports immune regulation and may reduce risk of autoimmune and allergic conditions. Studies of children playing on forest-floor daycare yards, adults gardening with microbially-rich soil, and offices with living "green walls" all showed measurable immune benefits, including more regulatory T cells and anti-inflammatory cytokines. Researchers argue cities should be designed to encourage incidental contact with nature, since the benefits are substantial and the risks minimal.
HN Discussion:
  • Extends the article's premise to barefoot walking and broader physical contact with nature
  • Personal validation of avoiding excessive hygiene and letting good bacteria thrive
  • Highlights specific findings as remarkable and convincing evidence
  • ~Questions the proposed mechanism, suggesting the microbial explanation is just a plausible story
  • ~Suggests grounding (electrical discharge) may be the real cause rather than microbes
17.The two Christian saints who are the Buddha(signoregalilei.com)
245 points by surprisetalk 2 days ago | 201 comments | permalink
tl;dr: The Christian saints Barlaam and Josaphat, venerated by Catholic and Orthodox churches, are actually a retelling of the Buddha's life story, transmitted via Sanskrit ("Bodhisattva") through Persian, Arabic, and Georgian versions before entering the Christian tradition in the 10th century. The name "Josaphat" itself derives from "Bodhisattva," and though scholars had noted parallels for centuries, the Buddhist origin wasn't widely acknowledged until the mid-19th century. The tale illustrates how religious traditions have long absorbed and reinterpreted each other's stories across cultures.
HN Discussion:
  • Christianity's long history of absorbing local traditions supports the article's thesis
  • Religious stories are often recycled archetypes, reinforcing the article's cross-cultural transmission point
  • The article overreaches by conflating story-borrowing with deeper theological compatibility between traditions
  • The saints could have been real people whose lives providentially paralleled the Buddha's
  • Adds historical/contextual information about canonization and related saints without taking a stance
18.Antiquated HTML Snippets and Artefacts(vale.rocks)
240 points by patadune 2 days ago | 85 comments | permalink
tl;dr: A tour through obsolete HTML snippets that once littered websites due to browser wars, vendor extensions, and third-party integrations—things like IE's X-UA-Compatible, conditional comments, MSSmartTagsPreventParsing, Skype Toolbar opt-outs, Baidu transcoding blockers, Apple/Microsoft pinned-site meta tags, PICS content labels, and Twitter card metadata. The author catalogs each with historical context, explaining why they existed and what (if anything) replaced them, noting many persist in legacy markup despite being irrelevant today.
HN Discussion:
  • Reminiscing about other obsolete web quirks like charsets, BOMs, and complex doctypes
  • Sharing additional forgotten artefacts the article missed, like PNG alpha hacks and Safari Pinned Tabs
  • Correcting factual details in the article, such as Smart Tags never actually shipping
  • Appreciating the catalog as a practical reference for compatibility work
  • ~Lamenting the loss of some old technologies like XSLT processing instructions
19.Mistral raises €3B(mistral.ai)
841 points by kuberwastaken 2 days ago | 593 comments | permalink
tl;dr: Mistral raised €3B in a Series D at a €21B+ post-money valuation, led by Samsung Electronics with EQT's Scaleup Europe Fund and PSG Equity — the largest equity round ever for a European tech company. The funds will expand frontier research, compute capacity, and international growth, positioning Mistral as a full-stack "sovereign AI" provider offering open-weight models, infrastructure, and products to enterprises and governments seeking control over data and deployment.
HN Discussion:
  • Mistral's contrarian sovereign AI strategy is smart and shouldn't be judged on benchmarks alone
  • EU-based location gives Mistral a sovereignty advantage that will attract government and enterprise clients
  • Mistral's LLMs are not competitive with other open-weight models despite decent auxiliary offerings
  • Mistral's revenue and salaries are too low to realistically compete with US labs
  • EU would be better served funding datacenters to run Chinese SOTA models rather than Mistral
20.I resigned from Anthropic today(twitter.com)
682 points by yurivish 1 day ago | 968 comments | permalink
tl;dr: Summary not available.
HN Discussion:
  • The claim that AI is uniquely dangerous is hyperbole; other threats like nuclear weapons and climate change are worse
  • ~Applauds the author for acting on principles even while disagreeing with doomsday takeoff scenarios
  • Skepticism of the author's claims lacks imagination; disaster paths are plausible given emerging capabilities
  • Danger comes from the full system (tools, autonomy, agents, credentials), not the model alone
  • ~Even if we agree AI is dangerous, individual/national action is futile due to geopolitical arms race dynamics
