RIP Val Kilmer: Real Genius .. the Film Nerd Culture Deserves (2015)

Emotional reactions & nostalgia

  • Many commenters describe Real Genius as a formative, “foundational” movie of their youth, especially for Gen X nerds.
  • Several plan re‑watches in tribute, often with their kids; some explicitly thank Kilmer for shaping their view of what their future could be.
  • A few had never heard of the movie and are adding it to watchlists now, prompted by the thread and Kilmer’s death.

Depiction of geeks, college, and Jordan

  • The film is praised as one of the most accurate and human portrayals of scientists/engineers: idiosyncratic, funny, intense, not caricatured like in Big Bang Theory.
  • The “nerdy girl” character is especially beloved; for some she was an early crush and proof that being a geek could be cool.
  • The movie’s version of college—late nights, lasers, pranks, weird roommates, co‑ed chaos—is remembered as both aspirational and surprisingly close to reality for some viewers.

Quotability and favorite scenes

  • Commenters recall long runs of dialogue from memory, emphasizing how densely quotable the script is.
  • Standout scenes include: the silent acceptance of a student’s screaming breakdown in the study lounge, gas‑mask hijinks in the dorm, the over‑caffeinated banter, and Jordan’s manic projects.
  • Some still reuse lines in work and life (e.g., the “decaffeinated brands” retort, the “moral imperative” phrasing).

Ethics of technology and weapons

  • One view: the film is “marred” by its stance that working on a military laser is bad; the tech itself would be “neat.”
  • Counter‑view (strongly supported): that ethical critique is the core of the movie—its lesson is that engineers must consider how their work will be used, not just the coolness of the tech.
  • This connects to modern tech: long hours for projects later used harmfully, followed by layoffs; calls to “look up once in a while” and accept responsibility.

Influence on careers and nerd culture

  • Multiple commenters credit Real Genius, WarGames, and similar films with nudging them into physics, engineering, or “doing science for a living.”
  • It’s repeatedly cited as “geek solidarity” and a counter to the “nerds vs jocks” stereotype, even as some discuss how bullying dynamics really worked in their schools.

Val Kilmer’s broader legacy

  • Alongside Real Genius, commenters celebrate Top Secret!, Tombstone, Heat, The Saint, Kiss Kiss Bang Bang, and more, noting his range from absurd comedy to intense drama.
  • Specific performances (especially Doc Holliday and his late cameo in Top Gun: Maverick) are called out as iconic and deeply affecting.

Early internet & fan connections

  • One long anecdote recounts emailing a contributor to the film’s computer graphics in the mid‑80s, then reconnecting ~40 years later, sparking a subthread about UUCP, bang paths, BITNET, and how “email” worked pre‑Internet.
  • Commenters see this as an example of the net’s original promise: connecting people over shared niche enthusiasms like Real Genius.

Coffea stenophylla: A forgotten bean that could save coffee from extinction

Caffeine, Perception, and Plant Biology

  • Debate over whether early coffee use via chewing cherries could produce a noticeable stimulant effect; several argue that in a caffeine-naive population even small doses would be felt.
  • Comparisons of caffeine sources: tea vs coffee vs chocolate vs yerba mate, with anecdotes about extreme sensitivity and extreme consumption.
  • Noted that brewed tea has less caffeine largely due to dilution, not leaf content; matcha and mate called out as strong alternatives with different subjective “feel.”
  • Explanation that tea and coffee evolved caffeine production via different metabolic pathways; caffeine acts as a pesticide and deterrent, which may interact with climate and pest pressure.

Coffee Species, Flavor, and Decaf Issues

  • Interest in alternative species: stenophylla (from the article), eugenioides (described as uniquely, naturally sweet with very low bitterness), robusta, and liberica.
  • Some hope for lower-caffeine but non-decaffeinated varieties to preserve flavor.
  • Robustas are defended when high quality, especially in Vietnamese coffee and hybrids (e.g., Catimor) that combine hardiness with better cup quality.
  • Decaf processing described as structurally altering beans (more porous, brittle), affecting roasting behavior, grind, extraction, and flavor; explains why decaf often tastes “flat” and behaves oddly in espresso.
  • Cascara (coffee cherry husks) mentioned as a tea-like drink with noticeable kick.

Native and Alternative Caffeinated Plants

  • Yaupon holly highlighted as a drought-tolerant, North American source of caffeine and theobromine; some speculate about breeding it for higher caffeine.
  • Discussion of its off-putting Latin name (Ilex vomitoria), possibly chosen to protect colonial tea interests; broader talk about rebranding unappealing plant names.
  • Yerba mate, “Mormon tea,” and other Ilex/Zanthoxylum species discussed as examples of underused native or regional stimulants.

Climate Change, Extinction Framing, and Risk

  • Some dismiss talk of “coffee extinction” as alarmist, arguing coffee has always faced crop failures and production can shift geographically.
  • Others counter that even without literal extinction, climate-driven volatility in a climate-sensitive, regionally concentrated crop can make arabica scarce and expensive.
  • Broader argument over “everything being blamed on climate change,” specific wildfire-attribution studies, and how to separate natural variability from anthropogenic effects.
  • A precautionary viewpoint emphasizes using early warnings to diversify species and growing regions.

Culture, Religion, and Stimulant Use

  • Regional preferences debated: claims that Asia/Australia “prefer tea” are challenged with data and anecdotes about strong coffee cultures (e.g., Australia, Taiwan, Vietnam, Indonesia).
  • Utah/LDS coffee bans spark discussion of health vs obedience, comparison with other religious dietary codes, and whether tea/coffee prohibitions still have a health basis.
  • Several see global stimulant use (especially caffeine) as a systemic labor issue—“a whip at the back of the worker”—while others insist they drink mainly for taste.
  • Parallel drawn to ubiquitous internet addiction and constant stimulation, with worries about burnout and loss of presence.

Water Use and Plant Efficiency

  • One commenter notes plants’ apparently “inefficient” water use (most lost to transpiration), with a reply that large-scale transpiration itself drives future rainfall and climate patterns.

Reception of the Article and Coffee Diversity

  • Multiple readers praise the article’s long-form, historical treatment and express strong interest in tasting stenophylla and other lesser-known coffee species, even when past experiments (e.g., racemosa) tasted very unlike familiar arabica.

Ferron – A fast, memory-safe web server written in Rust

Benchmarks & Performance Claims

  • Multiple commenters ask for public, reproducible benchmarks and the benchmark code; without that, they consider any “fast” claim weak.
  • Several question why nginx is absent from Ferron’s comparison charts, especially since nginx is mentioned as the source of the default test page. Some assume omission implies nginx is faster, but this remains unclear.
  • Others caution that even with benchmarks, results can be misleading: test setup, what’s measured, and bias matter a lot.
  • One points out Ferron’s own chart showing Apache prefork beating event MPM and finds that suspicious.

Comparisons to nginx, Caddy, and Other Rust Servers

  • Some see Ferron as a Caddy-like server in Rust and welcome an alternative, especially appreciating auto-TLS and potentially clearer config for complex setups.
  • Several people explicitly request benchmarks versus nginx, as that’s what they actually use; comparisons to lesser-known servers are less useful to them.
  • TechEmpower results and other Rust static servers are cited to show the Rust ecosystem is already very fast, but others counter that “written in Rust” does not guarantee real-world performance.
  • A concrete example with Rocket (Tokio + Hyper) vs nginx serving a 1GB file shows Rocket ~10–25x slower, largely due to small buffered reads/writes and lack of sendfile. This is used to argue implementation details dominate language choice.

Features, Defaults & Documentation

  • Ferron’s author confirms it uses Tokio + Hyper, supports HTTP/2, OCSP stapling, auto TLS, reverse proxying, and Slowloris protection via header and response timeouts (with some configurability questions).
  • Users ask for a prominent, concise feature list and clearer differentiation from other servers.
  • The FAQ splits opinion: some find “what is a web server?” patronizing; others like having basic context. Consensus: you can’t please everyone.
  • Minor UX feedback: the logo was unreadable in GitHub dark mode; this was quickly fixed.

Security, Deployment & TLS

  • There’s a detailed side discussion on how nontrivial security really is (duplicate headers, encoding, spec ambiguities, CVE history).
  • Several criticize the “curl | sudo bash” install on the homepage as incompatible with a strong security posture; they prefer OS package managers or rootless containers. The author suggests reviewing the script or using Docker images.
  • On architecture, some ask if servers should still bundle TLS when many people terminate HTTPS at a reverse proxy or cloud load balancer; others note this introduces extra moving parts, and Ferron itself can also act as the reverse proxy.

Language Choices & Memory Safety Debate

  • A Go vs Rust subthread discusses ecosystems (Go has richer web tooling, Rust has no GC-based runtime) and memory safety models.
  • A lengthy tangent debates whether Rust “has garbage collection” via Rc/Arc (reference counting as a subset of GC) versus the common view that Rust’s primary model is ownership/borrowing without a tracing GC.

UCSD: Large Language Models Pass the Turing Test

What the Turing Test Means (and Whether This Counts)

  • Several commenters stress Turing’s “imitation game” was a philosophical tool about intersubjective recognition, not a precise engineering benchmark.
  • Others argue the test is really about humans’ susceptibility to being fooled, not about machine intelligence.
  • Some say this result mostly indicts the Turing test: LLMs clearly can’t replace humans in many intellectual tasks yet still “pass,” so the test is weak as an intelligence measure.
  • There’s debate whether GPT‑4.5 being picked as “human” 73% of the time is a pass or a fail:
    • One view: success should be ~50%; any deviation shows systematic difference, hence distinguishability.
    • Counterview: from the interrogator’s binary perspective, consistent misclassification still shows the model is more human‑seeming than the human.

Methodology, Interrogators, and Prompting

  • Original Turing 5‑minute duration is noted; some ask what happens with longer, richer conversations.
  • Released transcripts show many interrogators doing minimal small talk for course credit, not serious adversarial probing.
  • Commenters suggest stronger incentives (cash rewards) and explicit encouragement to “break” the system would matter.
  • People highlight that prompting (“humanlike persona”) drastically changes outcomes; baseline GPT‑4o/ELIZA do poorly, GPT‑4.5 with persona does very well.
  • Some argue trivial jailbreak or policy‑violation prompts could still easily reveal many current LLMs, so this setup is not an “accurate” Turing test.

Philosophical Debates: Understanding vs. Imitation

  • Long subthread on the Chinese Room:
    • One side: symbol manipulation without environmental grounding cannot yield real “meaning”; LLM‑style competence is only syntactic.
    • Other side: if the overall system behaves as if it understands, insisting it “doesn’t really” is arbitrary or dualistic; human brains are likewise composed of non‑understanding parts.
  • Some emphasize that human intelligence crucially involves a world model tied to perception and action, which current LLMs largely lack.

Implications and Risks

  • Many express concern that models judged “more human than humans” could be especially persuasive in debate, propaganda, or scams.
  • Commenters note that RLHF explicitly trains models to be engaging and likable, which likely biases humans toward selecting them as “human.”
  • Others see this as a Goodhart’s law effect: once “sounds human” becomes the optimization target, systems become excellent at that specific surface criterion without deeper intelligence.

Supervisors often prefer rule breakers, up to a point

Applicability of the NHL-Based Study

  • Some see the NHL context as too “game-like” and morally insulated to generalize to workplaces; others argue high-level sports clearly involve real leadership, risk, and decision-making.
  • Debate over whether penalties/fouls in sports are “rule-breaking” or simply part of the designed tradeoff system (take a penalty to stop a sure goal).

Rule-Breaking in Sports vs “Real World”

  • In many sports, strategic fouls are explicitly priced into the rules; they’re not cheating but a legal tradeoff.
  • Clear distinction between:
    • Strategic penalties that benefit the team.
    • “Dumb” penalties and violations of unwritten norms.
    • Dangerous or maiming behavior, which is strongly discouraged.
  • Some commenters think the paper misreads this structure; penalty-taking can be an expression of game intelligence, not deviance.

Why Supervisors May Favor Rule-Breakers

  • Many supervisors (and some commenters) admit they reward people who understand when to bend rules for better outcomes.
  • Rule-breaking is seen as a signal of commitment, judgment, and mission-focus—“engaging with rules with purpose.”
  • However, support from supervisors stops where their own risk, ethics, or career are threatened.

Types and Purposes of Rules

  • Repeated distinction between:
    • Red-tape rules vs. critical, must-never-break rules.
    • “Forbidden good behavior” vs. “allowed bad behavior.”
  • Understanding why a rule exists (Chesterton’s fence analogy, “business logic in code”) is presented as crucial before deciding to follow or bend it.
  • Some rules are written mainly for plausible deniability; in practice “actual rules” are what get enforced, unevenly across hierarchy.

Liability, Power, and Selective Enforcement

  • Supervisors can reap rewards from subordinates’ rule-breaking while offloading blame when things go wrong.
  • Systems may be designed so workers must break rules to get work done, shifting responsibility away from leadership.
  • Examples include military “E4 Mafia,” corporate finance/trading cultures, and steroid/blackmail dynamics in sports.

Backlash and Ethical Concerns

  • Some workers resent rule-breakers because coordinated rule-following (e.g., focus hours, documentation) collapses when a few ignore norms.
  • There’s concern about “normalized deviance” and catastrophic failures when rule-breaking becomes standard.
  • Commenters emphasize balancing flexibility with ethics and recognizing that blind rule-following can be harmful, but so can casual rule erosion.

Where does air pollution come from?

Vehicle, combustion, and “hidden” pollution sources

  • Several comments stress non-exhaust emissions: tire and brake dust are seen as major particulate sources, especially in cities and colder climates with studded tires and road sand.
  • EVs are noted as better for brake dust (regen braking) but potentially worse for tire wear due to higher weight and fast acceleration.
  • Wood burning (fireplaces, stoves, BBQs) is highlighted as a surprisingly large and often affluent-driven source of local particulates, in some places rivaling traffic.
  • Sea spray and other “natural” PM2.5 sources exist, but commenters are unsure how their toxicity compares to combustion-derived particles.

Health impacts and metrics (deaths vs QALYs)

  • Debate over whether pollution “mainly kills the frail who would die soon anyway” is pushed back on: people report clear symptom relief during COVID traffic reductions and when leaving dense cities.
  • Pollution is framed as a “frailty multiplier” like starvation, shifting people into disease and death they might otherwise avoid.
  • Discussion favors considering quality-adjusted life years (QALYs), but some argue lifespan and healthspan effects are roughly proportional, so death counts already imply large morbidity.
  • Examples cited include asthma (especially children), cardiovascular damage, developmental harm, cancer, and possible links to hypertension.

Data, attribution, and monitoring

  • Some skepticism about “hard proof” is met with references to extensive citations; others note that many estimates (especially outdoor contributions) are model-based.
  • Indoor pollution from cooking, fireplaces, oil lighting, candles is widely accepted as clearly harmful.
  • Under-5 air-pollution death rates in several African countries prompt debate over whether other causes (malnutrition, infections) are larger but correlated.
  • Local monitoring gaps are a concern: polluted small towns may “disappear” in national stats if sensors are sparse or badly placed; micro-environments within cities (busy streets vs parks, beaches) can diverge strongly from city averages.

Inequality, politics, and regulation

  • Pollution burden is seen as regressive: poorer communities live nearer roads, ports, and industrial sites, echoing industrial-revolution patterns.
  • Attempts to curb urban pollution (e.g., stricter vehicle zones) often face intense political backlash.
  • Shipping’s SO₂ cuts (IMO 2020) surprise some; possible explanations include port rules, fines, insurance constraints, and the fact that costs were imposed uniformly so operators could all raise prices.

Agriculture, consumption, and global trends

  • Many sectors’ emissions are declining, but agricultural ammonia and methane show little progress; changing global diets is seen as harder than regulating a few industrial actors.
  • Meat and dairy, especially cattle, are repeatedly flagged; lab-grown meat is discussed but current environmental gains seem unclear.
  • Commenters stress “outsourced pollution”: rich countries claim green progress while importing goods (and associated emissions) from elsewhere; per-capita consumption-based CO₂ figures for some wealthy countries remain high or rising.

Personal mitigation and technology

  • Individual steps mentioned: wearing well-fitted N95 masks in heavy pollution, using HEPA purifiers (commercial or DIY Corsi–Rosenthal/box-fan builds), monitoring indoor air, and considering solar for cleaner power.
  • Balancing indoor filtration with fresh-air ventilation and CO₂ buildup is noted as an unresolved practical challenge.

Move fast, break things: A review of Abundance by Ezra Klein and Derek Thompson

Is “Abundance” just supply-side / deregulation?

  • Some see the agenda as repackaged supply-side economics or “growth-ism” with a Democratic gloss.
  • Others argue that lumping it together with right-wing deregulation (e.g., tariffs, drill-only energy policy, NIMBY politics) erases major differences in goals and methods.
  • There’s disagreement over whether the current Republican project is actually degrowth in practice, despite pro-growth rhetoric.

Coherence vs vibes: is there a real framework?

  • A central criticism of the book and of “abundance” is that it’s an inspiring value statement but not a coherent policy framework.
  • Critics say the book strings together anecdotes that point in opposite directions (e.g., outsourcing dooms California HSR but enables vaccine rollout) without deriving clear, generalizable rules.
  • Defenders respond that the point is not a universal template but a political vision: prioritizing outcomes and demonstrated competence over process purity.

Democratic coalition and intra-left conflict

  • Several comments frame the backlash as an internal Democratic fight: progressives want large universal programs (e.g., single payer), while “abundance” proposes a different long game—govern well where Democrats already rule, especially on housing and infrastructure.
  • Some on the left say it’s ironic that the author once called Medicare for All politically unrealistic but now backs an agenda that also confronts entrenched interests.

Regulation, competence, and case studies

  • Broad agreement that some regulations are counterproductive; sharp disagreement on how to identify which.
  • Critics fault the book for not naming enough concrete statutes to repeal or redesign.
  • Supporters say diagnosing pathologies (local veto points, consultant-driven megaprojects, box-checking bureaucracies) is valuable even without a detailed repeal list.

Housing, zoning, and NIMBY dynamics

  • The housing chapter is widely praised as the strongest and most concrete.
  • Commenters detail how zoning, environmental review, and local hearings empower existing homeowners (often older, wealthier) to block multifamily housing.
  • Debate over who should decide land use: property owners alone, neighbors, city, or state. Some emphasize zoning’s racist origins; others focus on school-funding inequities tied to property values.
  • There’s pushback on the idea that upzoning always hurts homeowners’ wealth; some argue long-run effects are more nuanced.

Growth, “more stuff,” and losers in a positive-sum world

  • Disagreement over whether “the last thing society needs is more stuff” is meaningful or just a luxury belief of the affluent.
  • Others recast the issue as misallocation and inequitable access rather than absolute scarcity.
  • Multiple comments focus on political economy: even in positive-sum changes, some groups perceive themselves as losers (e.g., NIMBYs), and compensating or over-ruling them is hard both practically and normatively.

Show HN: I vibecoded a 35k LoC recipe app

App functionality & UX

  • Core pitch: hands-free, voice-controlled recipe app without long SEO prose. Several users found the voice interaction “slick” and surprisingly effective (“show me the third one” worked instantly).
  • Others liked the simple, ingredients-first layout and considered it one of the better recipe UIs they’ve used.
  • Numerous bugs and rough edges reported: Firefox white-screen on generation, slow loading, scroll position not reset when viewing a recipe, broken links with certain non-ASCII titles, intermittent downtime while scaling the Heroku database.
  • Minor UX feedback: microphone icon should animate while listening, some searches briefly show results then crash.

AI-generated recipes & images

  • All recipes and photos are AI-generated. Many commenters found the images deeply uncanny and unappetizing.
  • Users rapidly discovered surreal, obscene, and dangerous recipes: bodily fluids, human/animal body parts, cyanide, cocaine, bombs, radioactive waste, “diarrhea walnuts” at 950K oven temperature, etc.
  • Some found this hilarious and treated the app as a toy; others saw it as evidence that AI-generated food content is unsafe and unserious.

Content moderation & safety concerns

  • Strong calls to add moderation: block bodily fluids, illegal drugs, explosives, hate speech, and obviously inedible or lethal ingredients.
  • Suggestions: run an AI safety filter on completed recipes and only surface “sensible” ones publicly, keep user-specified weirdness private.
  • Legal and reputational risk was highlighted (e.g., drug and bomb “recipes”).

Vibecoding practice & 35k LOC debate

  • “Vibecoding” is described as letting an LLM build most of the app from high-level prompts, accepting code that “feels right” rather than line-by-line review.
  • Many are alarmed by a ~35k LOC codebase for a relatively simple app, calling it “slopcoding” or a maintainability and security red flag (duplication, inconsistent logic, over-verbose React patterns).
  • Others argue LOC inflation will become normal: LLMs produce features humans wouldn’t bother to hand-code, and future tools (and LLMs themselves) will maintain this code.

LLM tooling, workflows, and limitations

  • Multiple reports that LLMs often silently rewrite unrelated business logic, undo manual changes, or “improve” files far beyond the requested edit; automated tests were later added to catch this.
  • Some see full-on vibe coding as chaotic and prefer using LLMs for autocomplete, rubber-ducking, or localized edits.
  • Workflow tips shared: narrowly scoped prompts, explicit “don’t touch anything else,” conventions files, tools like Cursor, Windsurf/Claude Code, Aider, and memory banks.

Business, cost, and ethical questions

  • Concerns about OpenAI audio API and hosting costs with no monetization; some doubt the app’s viral or revenue potential.
  • Broader ethical criticism: flooding the web with AI recipe “slop” degrades the commons and makes finding real, tested recipes harder.
  • Counterpoint: many users already rely on LLMs for flexible, on-the-fly cooking guidance; they see this app mainly as a tech demo of how far agentic coding has come.

Why are credit card rates so high?

Personal responsibility vs. structural drivers of credit use

  • Some argue credit cards would be unnecessary if people had financial discipline, emergency savings, and delayed gratification.
  • Others counter that people often need essentials (e.g., healthcare) they can’t afford, so credit fills a survival gap, especially with stagnant wages and high costs.
  • Several note that even in countries with little credit-card culture, people still take out small, often unnecessary loans, so debt isn’t only about discipline.

Why credit dominates over debit/cash

  • Many users never carry a balance and treat cards as a payments tool: convenience, recurring billing, itemized statements, no need to carry cash.
  • Rewards and cashback are a major draw; some optimize card choice per purchase and treat it as “free money” if they always pay in full.
  • Building a credit score is another strong motive, especially in the US.
  • Some highlight the time value of money: an interest‑free float of 30–45 days that can sit in interest‑bearing accounts or investments.

Fraud and consumer protection

  • Widespread belief: credit cards have much better fraud and chargeback protection than debit.
  • Others note that US law and network “zero liability” policies give debit similar formal protections, but:
    • With debit, stolen funds leave your account until the dispute is resolved.
    • With credit, it’s the bank’s money at risk; your cash balance isn’t disrupted.
  • In Europe, some say debit protections and usage are more robust, reducing reliance on credit.

Rewards, cross-subsidies, and ethics

  • Strong consensus that merchants bake interchange fees into prices, so all consumers fund rewards.
  • Debate over who ultimately subsidizes whom:
    • One view: high‑interest revolvers cross‑subsidize transactors and marketing.
    • Another, aligning with the article: interchange alone covers rewards; high interest is driven more by operating costs and undiversifiable default risk.
  • Some users feel uneasy benefiting from rewards that are ultimately funded by higher prices and others’ misfortune.

Merchant economics and system critique

  • Merchants often add ~3%+ to prices to cover card fees; cash is not free either (theft, handling, counterfeit).
  • US interchange is seen as unusually high versus EU caps; credit networks are described as entrenched “scammy middlemen.”
  • Pay‑by‑bank and instant payments (FedNow, etc.) are cited as emerging lower‑cost alternatives, but adoption is slow.

Why rates are so high (per article and comments)

  • Commenters highlight the article’s finding:
    • High card APRs are not mostly about charge‑offs or rewards.
    • Major drivers are high operating/marketing expenses and the fact that card lenders can’t easily diversify away from systemic downturn risk.
  • Others add a simpler explanation: issuers charge what the market will bear because borrowers have few alternatives.

The state of binary compatibility on Linux and how to address it

glibc ABI and toolchain strategies

  • Several commenters note the article omits the “right way” to target older glibc: using linker VERSION scripts (binutils ld support) to pin symbol versions, including glibc internals, so binaries built on new distros run on older ones.
  • Others point out the importance of -static-libgcc and -static-libstdc++ for C++ compatibility; missing those has bitten projects (including games) for years.
  • A recurring complaint is that standard Linux toolchains implicitly target the host’s glibc, making it hard to cross‑compile to older ABIs. Zig’s toolchain is praised for solving this (via glibc ABI metadata and sysroots) and making “target glibc X.Y” trivial.

Static vs dynamic linking, and why libc is special

  • Many participants argue “just statically link” is not a general solution:
    • glibc’s NSS and PAM stacks rely heavily on dynamic loading.
    • GPU stacks (OpenGL/Vulkan drivers) and some plugins are only provided as shared objects.
    • Mixing static linking with dlopen is described as fragile, especially when multiple libcs or allocators are involved.
  • Others counter that dynamic linking has its own long‑term maintenance issues and suggest stricter backwards‑compatibility guarantees or “base” APIs that never break.

Fragmentation, distros, and packaging

  • Multiple comments stress that Linux ≠ one OS; each distro (and even each major release) is effectively its own platform, with no shared ABI authority.
  • The practical advice: target a small set of enterprise/LTS distros; expect to rebuild per major version; or ship source and let distro maintainers/package managers integrate it.
  • Python’s manylinux effort is cited as an example of how hard it is to depend on anything beyond glibc/libstdc++ without bundling.

How good/bad is glibc really?

  • Some argue glibc maintains old symbols extremely well and that the real problem is running new glibc‑built binaries on old systems, not vice versa.
  • The proposal in the article to split glibc into separate loader/libc/threading libraries is criticized as not actually fixing the cited regressions and being technically entangled (TLS, syscalls, loader interactions).
  • Others say glibc’s tight coupling with the dynamic loader prevents shipping multiple libc versions side‑by‑side and thus is a major distribution pain point.

Alternatives and workarounds

  • Mentioned approaches include: polyfill‑glibc shims, Go binaries built with CGO_ENABLED=0, Nix/NixOS style isolation, containers, Wine/Win32 as the “only stable ABI,” and niche tools like Rugix or Cosmopolitan (with skepticism about malware flagging).

Silicon Valley, Halt and Catch Fire, and How Microserfdom Ate the World (2015)

Nostalgia for Grantland, Microserfs, and 90s Tech Culture

  • Multiple comments mourn the loss of Grantland and praise its long-form, thoughtful writing compared to later successors.
  • Microserfs is remembered fondly as a near-definitive snapshot of early-90s tech work: anxiety, idealism, and pre-dotcom innocence.
  • Halt and Catch Fire and Silicon Valley are praised for capturing the manic optimism of emerging tech waves, even when we “already know” how history turns out.
  • Some regret that later, stronger seasons of Halt and Catch Fire didn’t get comparable critical coverage.

Computing, Advertising, and Surveillance Capitalism

  • Several posters argue computing was better before it was captured by advertising and DRM: locked bootloaders, “cash register” phones, and pervasive tracking are blamed partly on Hollywood’s demand for control.
  • Advertising is called a societal “cancer” and equated with propaganda: shaping culture, normalizing manipulation, driving consumption, and contributing to political dysfunction.
  • Others push back: psychological research shows behavior change is hard; much ad spend mostly reallocates demand among similar products and is often poor ROI.
  • Debate emerges over whether “honest” advertising exists; critics say emotional manipulation and lifestyle branding always outcompete straightforward product information.
  • Proposals floated: stricter regulation of data collection, treating ads like pollution, or radically reducing ad-funded services. Counterpoint: ads currently fund independent media; removing them without replacement could be worse.

Work, Meaning, Wage Labor, and Systems

  • One thread riffs on the “dream of the 90s” that work and authentic self could align. Some see this as a noble quest; others as another form of escapism or denial of mortality.
  • Strong critiques of wage labor: it more often produces “Severance”-style alienation than meaningful vocation. Many argue people want to produce, but on their own terms.
  • Proposed alternatives include UBI or guaranteed basics, with work chosen for meaning and supplemented by incentives for unpleasant jobs, plus automation.
  • Detractors invoke “human nature” and the historical failures of communism: lack of incentives, bad planning without price signals, corruption, and eventual coercion.
  • This broadens into a capitalism-versus-communism morality fight: one side emphasizes market coordination and wealth creation; the other stresses externalized harms, inequality, and moral blind spots about how wealth is accumulated.

Future Tech Waves and Funding Models

  • One commenter sees a coming multi-decade boom driven by small ML/RL startups solving real-world engineering/logistics/robotics problems, akin to the early internet era.
  • They argue existing tech is enough to create huge value; what’s missing is small, fast pre-seed funding and investors who recognize non-LLM AI opportunities.
  • Many are skeptical of angel investing as a “chump’s game” that underperforms simple index funds, with status-seeking as a major motivator.
  • Discussion of alternatives: government grants (with real-world examples of capture and abuse), traditional VC, philanthropy, or a return to bootstrapped, revenue-first products.

Miscellaneous

  • Several users appreciate the article’s hand-drawn illustration, explicitly contrasting it with contemporary “GenAI slop.”
  • A few lament that HN itself has become more crowded with marketing/sales voices, echoing the broader “ads ate everything” theme.

How Silica Gel Took Over the World

Practical uses & regeneration of silica gel

  • Commenters use silica gel widely: in hygroscopic fertilizers, 3D-printing filament storage, long-term clothes storage, cars (against condensation), and as crystal cat litter / loose desiccant in vehicles and luggage.
  • Many recharge packets by heating: oven at ~120°C for hours, food dehydrators, low-temperature microwaving in short bursts, or even leaving on warm electronics.
  • Emphasis on airtight storage after drying (canning jars, small glass spice jars, good plastic containers, vacuum bags). Otherwise the gel slowly rehydrates in storage and is useless for “emergency” drying.
  • One person argues most consumer packets are effectively cosmetic because they’re saturated before reaching end users, especially in non-airtight packaging; others question whether that’s universally true.

Desiccants, SAPs, and related materials

  • Superabsorbent polymers (SAPs/“Orbeez”) are highlighted: huge liquid uptake, used in diapers, plant watering, and toys; fun optical tricks (invisible in water) and glow-in-the-dark decorations.
  • Molecular sieve beads are mentioned as even more powerful desiccants, used inside double-pane windows and for rapid flower drying.
  • “Getters” and other moisture scavengers for vacuum devices and refrigeration systems are brought up as conceptual cousins.

Safety, toxicity, and “DO NOT EAT”

  • Multiple explanations for the ubiquitous warning:
    • Choking risk and resemblance to salt packets or candy.
    • Mixed use with food vs non-food products, so one global “DO NOT EAT” SKU is simpler.
    • Protecting children, especially when packets appear in instant ramen or snacks.
  • Chemically, silica gel itself is generally non-toxic and even GRAS in small amounts as a food additive, but dust can irritate lungs/eyes and large unmixed quantities might cause harm.
  • Indicator gels: cobalt chloride (blue↔pink) is effective but toxic/carcinogenic in dust or ingestion; safer orange/green formulations exist, especially for food-related uses.

Electronics drying & solvents

  • Silica gel for rescuing soaked electronics has mixed reviews; concerns that heated air (e.g., food dehydrators) may drive moisture deeper.
  • Several recommend rinsing boards in high-purity isopropyl or ethanol, then gentle warm-air or oven drying; they warn about damage to LCD/backlight stacks and certain plastics/inks.
  • There’s a long subthread on using alcohol in ultrasonic cleaners: effective but potentially flammable and vaporous; some use bag-in-bath techniques to mitigate risk.

Food preservation & oxygen control

  • Distinction between desiccant packets and oxygen absorbers: many flat “do not microwave” packets in jerky, bacon bits, seaweed snacks, etc., contain iron powder to scavenge oxygen.
  • For home oxygen removal, people suggest iron-based oxygen absorbers, vacuum sealing, or CO₂/N₂ flushing; produce bags with selectively permeable plastics are mentioned via a podcast.

Material properties & scale

  • The “800 m² per gram” claim is clarified via analogy: like crumpled tissue paper, silica gel has a huge internal porous surface area packed into a tiny volume.

Cultural & meta tangents

  • Thread includes jokes (candy imitating silica packets, comics, MST3K references), complaints about the article’s ads, and a side debate over whether religious/ritual traditions can truly persist 10,000+ years.

The Importance of Fact-Checking

Storytelling vs. Journalism

  • Several commenters draw a strong line between journalism and narrative storytelling: journalism must prioritize informing over entertaining, avoid speculation, and rigorously verify facts; narrative shows can shape, omit, and dramatize more.
  • Others push back, arguing this distinction is fuzzy and often abused (“we’re just entertainment”) to dodge responsibility for truth.
  • There’s debate over whether This American Life (TAL) should be treated as journalism at all, given its format and origins in public radio news ecosystems.

The Daisey/TAL Incident and Its Fallout

  • The Foxconn episode is seen as a textbook ethics failure: a highly compelling story that fit TAL’s narrative template but contained at least 13 major fabrications.
  • Some stress that TAL explicitly intends to tell true stories, so treating the show as “just storytelling” is a cop-out; others say the real mistake was tackling an investigative topic outside their core strengths.
  • TAL’s public retraction and adoption of professional fact-checkers is praised by some as exemplary accountability, while others argue one exposed fabrication should reduce trust in earlier episodes and raise questions about unexamined archives.
  • Comparison points: NYT’s Caliphate podcast, Der Spiegel’s Relotius scandal, older quasi-documentaries like Nanook of the North.

Narrative’s Power and Dangers

  • Many note humans are “addicted to narrative”: emotional arcs beat dry facts, making narrative the ideal vehicle for propaganda and hoaxes.
  • Commenters cite “emotional truth” defenses (Daisey, comedians, biographers, hate-crime hoaxes) as intellectually bankrupt and corrosive, because they give people excuses to justify lying for a “greater truth.”
  • Some argue arranging facts into a compelling narrative is intrinsic to journalism; others warn that pre-choosing a narrative and fitting facts (or fabrications) to it is where things go wrong.

Limits and Biases of Fact-Checking

  • Fact-checking is seen as necessary but insufficient:
    • You can mislead with 100% true but cherry‑picked facts, omit critical context, or imply false causal links.
    • Fact-checkers themselves can be biased or political, leading to selective scrutiny and loss of public trust.
  • Still, independent fact-checking is credited with catching outright lies like the Daisey story and similar fabrications.

Trust, Bias, and the Media Ecosystem

  • Some commenters strongly defend TAL (and NPR more broadly) as mostly reliable and uniquely willing to self-correct; others call them “bullshit factories” or cite other NPR mistakes as evidence of systemic problems.
  • There’s a broader argument over mainstream outlets aligning with government or “State Department” narratives versus genuinely exposing labor and human-rights abuses; commenters disagree whether overlap with official positions should itself be suspicious.
  • Examples from across the spectrum (TAL, CNN’s fake Syrian prisoner segment, Tucker Carlson, Rachel Maddow, Dominion Voting lawsuit) are used to show how outlets mix fact, opinion, and narrative while formally disclaiming factual responsibility in court.

Audience Responsibility and Skepticism

  • Multiple commenters emphasize that how audiences react matters:
    • Over-trusting a single outlet is dangerous; so is dismissing everything as lies.
    • Some advocate verifying with primary documents when possible, cross-checking multiple outlets, and being aware of one’s own confirmation bias.
  • Others are more pessimistic: many people care more about “vibes” than facts, are overconfident in their own knowledge, or treat any fact-check that conflicts with their narrative as partisan.
  • There is concern about raising a generation to “believe nothing,” which may leave them unable to navigate complex information where primary sources are inaccessible.

Glubux's Powerwall (2016)

Fire Risk and Safety Concerns

  • Many commenters see a massive DIY pack of mixed old 18650s as a serious fire hazard, especially in a wooden shed, with talk of “campfire-like” arrangements of cells.
  • Housing the pack ~50m away from the house is widely seen as the key mitigation: losing the shed is acceptable; preventing spread to dwelling and vegetation is the real goal. Some suggest gravel or paving, cinderblock construction, sand beds, or even burying the structure.
  • Lithium fires are described as self‑oxidizing and hard to extinguish; the realistic plan is often “let it burn while protecting surroundings.” A small extinguisher is viewed as useful only for very early-stage, non‑battery ignition—and currently badly placed in photos.
  • Several first‑hand anecdotes (electric skateboard, 400V pack, factory-like fires) reinforce how violent runaway can be and how long heat and smoke persist.

Battery Chemistry and Technology Choices

  • Multiple commenters contrast volatile NMC laptop cells with safer chemistries like LiFePO₄, which have lower energy density but far better thermal behavior for stationary storage.
  • Discussion notes that 18650s in metal cans don’t balloon visibly like pouch cells but can still swell at terminals and fail catastrophically.
  • Some point out that commercial home batteries use prismatic or large LFP cells with robust BMS, fusing, thermal paths, and sometimes fire arrestors—very different “trenchcoats” than DIY packs of random laptop cells.

DIY vs Commercial Systems and Economics

  • Strong split: admiration for the ingenuity, persistence, and community around DIY powerwalls vs arguments that a modern LFP rack pack is cheaper, faster, safer, and more compact per kWh today.
  • Several commenters run rough numbers: in 2016 DIY reuse looked more rational; by 2025, ~15 kWh of new LFP cells plus enclosure is cited in the low-thousands of dollars, with hours of assembly instead of hundreds of hours of cell sorting and welding.
  • Others argue labor opportunity cost, insurance issues, and liability (no vendor to sue) make large DIY packs unsuitable for “normal” homeowners, but worth it for hobbyists who value the learning.

Recycling, Second-Life Cells, and Scalability

  • Philosophical divide: some celebrate extending life of laptop cells and avoiding landfill; others note that used EV or industrial packs, or direct materials recycling, may be more efficient at scale.
  • Automation of cell testing/sorting is often requested but questioned on economics and safety: mismatched impedances, parasitic charging, and liability make “repacked random cells” a tough commercial product.
  • Observations that many commercial packs (including EVs) are “lots of 18650s in a trenchcoat,” but with heavy engineering around binning, cooling, fusing, and monitoring.

Risk Perception and Comparisons

  • One camp stresses that random lithium fires are statistically rare, citing well-known phone incidents as tiny fractions of deployments.
  • Others reply that a hand‑wired shed full of mixed second‑hand cells is not comparable to a single phone pack, and the consequence profile (house, livelihood) justifies much more caution.
  • Broader debate touches on why high‑energy Li‑ion remains common in consumer electronics vs safer but less dense chemistries; several note society routinely accepts far riskier technologies (cars, gas stoves) with managed risk.

Article, Source, and AI-Writing Discussion

  • Multiple commenters dislike the secondary article that originally linked this project: it’s seen as light on technical detail, mislinked, and possibly LLM‑generated, with telltale vague phrasing and hedging (“likely required manual labor”).
  • The original forum build log is widely recommended as “the real content,” showing the full evolution, photos, and the surrounding DIY community.
  • Some meta‑discussion unfolds about how to recognize AI‑written prose, whether that matters, and frustration that mediocre AI rewrites are being used for SEO and ad clicks.

Alternative Storage and Backup Ideas

  • Suggestions range from “just buy LFP prismatic packs” to sodium‑ion home systems, gravity or mechanical storage, and pumped‑hydro‑like concepts—though commenters concede practicality and cost issues.
  • A side thread discusses more conventional backup: generators, automatic transfer switches, interlock kits, and subpanels—repeatedly emphasizing the need for licensed electricians when tying into mains.

We can, must, and will simulate nematode brains

Prospects for Simulating Brains (Human and Nematode)

  • Some see full brain simulation (up to human-level) as inevitable long‑term, starting from connectome mapping and scaling up.
  • Others argue “someday” is unjustified optimism: we can’t fully simulate even atoms or single cells yet, so a human brain may be practically or even fundamentally out of reach.
  • A middle view: mapping small regions (or simple organisms) is plausible and scientifically valuable, but extrapolating to whole-human simulation is wildly premature.

What Counts as a “Simulation”?

  • Thread repeatedly returns to: what does “simulate a brain” actually mean?
  • One camp is behaviorist: a simulation is good if it reproduces observable behavior for some purpose (e.g., nematode squirming, traffic flow, animal migration).
  • Another insists that reproducing a narrow slice of behavior (e.g., “quacks like a duck”) isn’t enough; accuracy depends on the objectives—predictive biology vs. artificial pets vs. philosophical copies of minds.

Technical and Scientific Obstacles

  • Strong emphasis on unknowns: incomplete understanding of neurons, synapses, neurotransmitters, graded vs. spiking potentials, body–brain interactions, hormones, gut–brain axis, and lack of non‑invasive high‑resolution measurement.
  • Skeptics highlight that current neuron models are gross simplifications; we can’t even model a single cell in full biochemical detail.
  • Dispute over whether we must simulate at atomic/quantum level or can rely on higher‑level abstractions, with analogies to CFD and weather forecasting (highly useful yet limited and data‑hungry).

Consciousness, Computation, and Substrate

  • Debate over whether consciousness can arise purely from computation or whether the physical substrate and specific dynamics (e.g., electrons vs. abstract algorithms) matter.
  • References to philosophical zombies and Chinese Room: a system could behave like a conscious agent yet be experientially empty.
  • Some argue brains are just physical systems obeying physics and thus in principle simulable; others note physical limits to computation and our ignorance of consciousness as reasons for caution.

Ethics, Immortality, and Inequality

  • Speculation on brain upload as “next phase of evolution” triggers mixed reactions: excitement about defeating death vs. fear of extreme inequality (“cheat codes” for the rich) and dystopian outcomes (digital suffering, “Neura‑hell”).
  • Some push a broader view that we already extend cognition with writing, tools, and computers—“we are already cyborgs.”

Nematodes as a Testbed and Skepticism of Grand Projects

  • Nematodes are seen as an appealingly simple but still very hard target where full‑organism simulation might be scientifically actionable.
  • There is criticism of past large‑scale brain projects that overpromised (e.g., EU initiatives), and concern that confident “we can, must, will” rhetoric risks burning resources on speculative goals.

  • Several commenters point out mismatches between “remote” labels and later fine print requiring hybrid or specific locations.

Candidate Experience & Hiring Practices

  • Repeated frustrations about:
    • Companies not responding or failing to send rejections after substantial effort (e.g., take‑home projects, multi-stage processes).
    • Roles reposted for months, leading to suspicion of “ghost jobs” or low intent to hire quickly.
    • Application funnels that require installing the company’s product or using buggy third‑party forms.
  • Some companies respond directly, acknowledging volume and trying to clarify that roles remain open and standards are high.
  • Moderators intervene to detach off-topic or overly negative accusations and remind posters of thread rules.

Trust, Authenticity & Criticism

  • Multiple accusations that specific postings are “fake” or scams; in at least one case the poster is challenged on factual grounds or admits a mix-up.
  • One role draws concern for requiring “personal support-raising” (fundraising for one’s own nonprofit salary).
  • Ongoing discussion about salary realism in EU startups and transparency around compensation and hiring geography.

Ask HN: Why hasn’t AMD made a viable CUDA alternative?

Perceived Root Causes

  • Many argue this is primarily a management/strategy failure: AMD has not treated software as first‑class, nor made GPU compute a top priority compared to CPUs and consoles.
  • Others stress history and timing: near‑bankruptcy around 2015, focus on winning console and CPU battles, and a bet on OpenCL that failed left them under-resourced and late.

Software Stack: ROCm, HIP, OpenCL

  • AMD does have a CUDA‑like language (HIP) and the ROCm stack, plus some emerging libraries, but:
    • Early ROCm was seen as awful to use; that reputation stuck.
    • Support is fragmented: only a few GPU SKUs are “official,” others “almost work” with hacks.
    • Documentation, tooling, and stability are widely criticized.
  • OpenCL was supposed to be the open standard, but lost to CUDA due to worse ergonomics, weaker documentation/community, and poor vendor follow‑through (including AMD’s).
  • Some say AMD over-relied on “open source will fix it” instead of funding a first‑class developer experience.

Hardware, Drivers, and Platform Issues

  • Reports of buggy, bloated drivers and painful setup (e.g., for llama.cpp) contrast with Nvidia “just works.”
  • PCIe atomics and motherboard firmware incompatibilities create nondeterministic ROCm failures; users can’t easily know if their board truly supports what ROCm needs.
  • Others note architectural/firmware differences: Nvidia offloads more to updatable on‑card firmware, making long‑term support easier.

CUDA’s Ecosystem and Network Effects

  • CUDA is described as an ecosystem: mature libraries (cuDNN, cuBLAS, NCCL, etc.), tools, examples, and extensive outreach (on‑site engineers, hackathons).
  • Its “moat” is seen less as the core language and more as completeness, stability, and continuity across generations.
  • Counterpoint: many ML users write little or no CUDA, relying on PyTorch/TensorFlow. If those frameworks run well on AMD, CUDA’s lock‑in weakens.

Leadership, Risk, and Investment Constraints

  • Debate over leadership style: AMD leadership is portrayed as more conservative, incremental, and beholden to a board versus Nvidia’s founder‑CEO willing to make huge, long‑horizon bets.
  • Several comments argue AMD simply hasn’t spent the billions and recruited the thousands of top engineers needed; efforts are “tens of millions” instead of “billions.”

Market Dynamics and Economics

  • AMD’s core wins have been in CPUs and consoles; the GPU compute market (segment “3”) only exploded recently.
  • Some argue it hasn’t been economically rational for AMD to chase Nvidia into a segment where Nvidia enjoys ~80% margins and near-total mindshare.
  • Others counter that those margins show there is ample room for a strong challenger, and that real competition would dramatically lower AI compute costs.

Current Efforts and Glimmers of Hope

  • ROCm/HIP have improved; people report working setups on recent APUs/GPUs and growing PyTorch ROCm support.
  • Third‑party projects like ZLUDA and Scale aim to run CUDA binaries/code on AMD via HIP/ROCm.
  • Tinygrad and related community work are seen by some as a promising “beyond CUDA” path, though others are skeptical of their maturity and impact.

Proposed Paths Forward

  • Commonly suggested moves for AMD:
    • Treat software as co‑equal with hardware; build a strong, empowered software org.
    • Provide full ROCm support across all modern GPUs and certify motherboards (“ROCm compatible”).
    • Open drivers more fully and collaborate closely with flagship open‑source projects (PyTorch, llama.cpp, etc.).
    • Differentiate on hardware with much larger, affordable VRAM pools to attract AI users despite weaker software.

Bletchley code breaker Betty Webb dies aged 101

Passing of WWII Generation & Living Memory

  • Commenters reflect on the emotional impact of losing the last WWII participants and the fear that their lessons are fading.
  • Several note that even earlier generations forgot their own ancestors’ struggles, implying a recurring cycle of amnesia.
  • Some share regret at missed chances to talk with veterans; others recall recent encounters with Bletchley staff and front-line soldiers.

Propaganda, Misinformation & Teaching History

  • Users debate how much WWII/Holocaust misinformation exists today; some in Europe say they rarely see it, others cite extreme online spaces featuring Holocaust denial and “Hitler was misunderstood” narratives.
  • A widely cited “1 in 4 young Americans” Holocaust myth stat is challenged; later comments say the original survey was flawed and exaggerated.
  • Multiple comments lament that history teaching is often boring, sanitized, or nationalist, and fails to convey complexity or relevance.
  • There’s disagreement over whether “patriotic history” is actively preferred or imposed by elites vs. mostly driven by anxious parents and culture wars.

War Crimes & Moral Complexity

  • Some argue Allied powers clearly committed war crimes (e.g., Red Army atrocities, firebombing of Japanese cities, internment of Japanese-American citizens).
  • Others say there’s broad factual agreement on events like Dresden or Hiroshima/Nagasaki, with disputes mainly over interpretation and necessity.

Bletchley Park Work & Legacy

  • Discussion highlights that many Bletchley tasks were painstaking clerical “human computer” work (e.g., card indexing at massive scale).
  • People note continuity between Bletchley-era methods and modern signals intelligence.
  • Some emphasize that veterans were bound to secrecy for decades, limiting historical records and even family knowledge.

Visiting Bletchley Park & Related Museums

  • Strong recommendations to visit both the main Bletchley Park museum (human story, Turing exhibits) and the adjacent National Museum of Computing (technical demonstrations, Colossus reconstruction).
  • Practical tips: check opening times, appreciate the stately home setting, and consider related museums (cryptologic, transport, Brooklands).

Books & Media Recommendations

  • Suggested non-fiction and semi-technical works on Bletchley/codebreaking, plus broader cryptography and WWII intelligence histories.
  • Recommendations also include documentaries (e.g., a series on Bletchley) and historical novels with codebreaking themes.
