I just want working RCS messaging

Where RCS Fails and Who’s Responsible

  • Many see the core problem as an accountability vacuum between three parties:
    • Apple insists activation is a carrier issue.
    • Carriers often outsource RCS to Google’s Jibe platform and tell users “it’s Google.”
    • Jibe is opaque to both customers and front-line support, so nobody can actually fix edge‑case failures.
  • Some argue it’s purely the carrier’s job (Jibe should behave like any other carrier backend), others think Apple could avoid this by running its own RCS servers but deliberately won’t.

Reliability, Activation, and Spam

  • Numerous reports of RCS:
    • Failing to activate or only working on certain SIMs, devices, or networks.
    • Toggling unpredictably between RCS and SMS.
    • Breaking group chats, especially when participants switch between Android and iOS.
    • Stalling on weak data instead of falling back cleanly to SMS, leading some to disable it permanently.
  • Several users describe severe RCS spam and “random group” scams, though others say their spam is overwhelmingly SMS/MMS, not RCS.

Platform / ROM and Carrier Interactions

  • Custom ROM users (GrapheneOS, LineageOS) report long‑running breakage:
    • Google Messages expects special permissions, Play Services, and attestation; without them, number verification or Jibe activation fails.
    • Some implementations appear tied to IMEI/IMSI, so moving numbers between phones or eSIM resets can create mysterious lockouts.
  • MVNOs and smaller carriers often lag in iOS RCS rollout or have partial implementations.

RCS, Google Jibe, and “Google-only” Reality

  • On paper, RCS is a GSMA standard carriers can self‑host.
  • In practice, for most major markets:
    • Carriers have abandoned or never deployed their own stacks and rely on Jibe.
    • Google Messages is effectively the only mainstream client.
    • Many commenters therefore consider RCS a de facto Google service, not a true, carrier‑neutral successor to SMS.

Security, Privacy, and Protocol Design

  • RCS originally shipped without E2EE; standardized MLS-based encryption only appeared in recent spec revisions and is barely deployed.
  • This fuels views of RCS as surveillance‑ and telco‑friendly, with cleartext metadata and easy spamability.
  • Others note it’s still an incremental improvement over SMS/MMS, but far behind Signal/WhatsApp in practice.
  • Tying identity to phone numbers and carrier infrastructure is seen by many as a fundamental privacy and design flaw.

Social Dynamics: iMessage, Kids, and Exclusion

  • Thread veers into US social effects:
    • iMessage dominance makes Android users and their “green bubbles” socially excluded in some teen groups.
    • Debate whether iMessage’s rich group‑chat UX directly amplifies bullying, or just hosts behavior that would exist on any platform.
    • Some parents deliberately keep kids on Android (or off smartphones) to avoid iMessage drama; others argue that withholding iPhones harms kids’ ability to participate socially.

“Why Not Just Use X?” – Competing Apps and Regions

  • Non‑US commenters say RCS is mostly irrelevant where WhatsApp, Signal, Telegram, WeChat, Line, or local apps dominate.
  • Others point out:
    • Network effects and older relatives mean “just use Signal/WhatsApp” is not always realistic.
    • Many dislike letting carriers control messaging at all and prefer pure IP, app‑layer solutions or federated systems (email/XMPP/Matrix).
  • There’s frustration that after decades, no open, widely adopted, secure, interoperable messaging standard has replaced SMS.

Meta‑Critique of RCS and Telco‑Driven Standards

  • RCS is frequently described as:
    • Design‑by‑committee bloat (“email over HTTP/SIP/XML wrapped in carrier cruft”).
    • A relic of the era when carriers controlled phone software and imagined users would install carrier‑branded messaging apps.
  • Several conclude that giving telcos any role beyond “dumb pipe” has doomed RCS to the same fate as MMS: complex, fragile, and unevenly implemented, while closed consumer apps continue to “just work.”

Show HN: I made a down detector for down detector

Humor, recursion, and “who watches the watchers”

  • Thread is dominated by jokes about infinite recursion: down detector for down detector “all the way down,” “N‑down detector,” and shorthand like downdetectorsx5.com.
  • People riff on “Quis custodiet ipsos custodes?” and Watchmen, plus classic “Yo dawg, I heard you like down detectors” memes.
  • Several gag domains are registered or checked, running into DNS label-length limits, prompting suggestions for more compact notation.
  • HN itself is jokingly called the “true down detector.”

How the site actually works (or doesn’t)

  • Users inspect the client code and find it generates deterministic mock data: no real checks, just pseudo-random response times and fixed “up” statuses.
  • This is seen as in keeping with the “shitpost” / novelty nature of the project.
  • Some ask how a serious detector should handle partial failures (e.g., Cloudflare’s human-verification page breaking while the origin still returns HTTP 200).
  • Others link external uptime checkers monitoring the site, effectively creating a real meta‑detector chain.

Redundancy, distributed detection, and graphs

  • Multiple comments suggest a second (or looping) instance to monitor the first, leading to ideas about directed graphs of monitors and distributed heartbeat networks.
  • One commenter outlines a distributed design: many nodes monitoring each other, clusters going silent as a signal of broader failure, with self‑healing to maintain resilience.
  • Another argues that it’s fine for DownDetector to monitor the meta‑detector, as long as they’re on different stacks/regions.

Cloudflare, CDNs, and infrastructure choices

  • The project appears to use Cloudflare DNS and AWS hosting; people note the irony that if major infra is down, this site likely is too.
  • Debate over whether a static status page genuinely needs a CDN:
    • One side: static + CDN is ideal for sudden traffic spikes and cheaper than over‑provisioned compute.
    • Other side: for basic static HTML, a CDN may be overkill if the origin is robust.

Centralization vs smaller / regional providers

  • A long subthread discusses moving from US hyperscalers (Cloudflare, AWS) to European providers (Bunny.net, Hetzner, Scaleway, Infomaniak) for reliability, sovereignty, and independence.
  • Some report zero downtime with these alternatives; others share concrete Hetzner incidents and note that EU providers also have outages.
  • Disagreement over reliability incentives:
    • Pro‑small: fewer services, less complexity, stronger incentive not to fail.
    • Skeptical: smaller players may use lower‑tier datacenters; their outages just don’t make headlines.
  • Separate debate over cloud vs on‑prem: some say cloud is overused and on‑prem can be cheaper and more sovereign; others argue replicating cloud capabilities in‑house is prohibitively complex.
  • Cloudflare and AWS outages (including a Rust unwrap mention and Crowdstrike’s past incident) are cited to question how much such events actually affect customer churn or stock price.

Related tools and alternatives

  • People mention other monitoring tools and services: uptime projects like hostbeat.info, Datadog’s updog.ai, and EU‑centric transactional email/self‑hosted options (e.g., Sweego, MailPace, Hyvor Relay).
  • Some readers say this thread makes them feel better about hacking on their own monitoring tools despite existing mature competitors.

Cloudflare outage on November 18, 2025 post mortem

Incident mechanics and scope

  • A ClickHouse permission change made a metadata query (system.columns without DB filter) start returning duplicate columns from an additional schema.
  • That doubled the Bot Management “feature file” used by Cloudflare’s new FL2 proxy; the file now exceeded a hard 200-feature limit.
  • The FL2 bot module hit that limit, returned an error, and the calling code used unwrap() on the Result, panicking and crashing the worker thread.
  • The oversized config was refreshed and pushed globally every few minutes, so the “poison pill” propagated quickly and repeatedly.
  • Old FL proxies failed in a “softer” way (all traffic got bot score 0) while FL2 crashed and returned massive volumes of 5xx errors.

Testing, staging, and rollout

  • Many commenters argue the failure should have been caught in staging or CI by:
    • Realistic data-volume tests or synthetic “20x data” tests.
    • Golden-result tests for key DB queries before and after permission changes.
    • Validating the generated feature file (size, duplicates, schema) and test-loading it into a proxy before global rollout.
  • Others note that duplicating Cloudflare’s production scale for staging is extremely expensive, but counter that:
    • You don’t need full scale for every commit; periodic large-scale tests and strong canarying would help.
    • Config changes that can take down the fleet should have progressive, ring-based rollouts and auto-rollback, not “push everywhere every 5 minutes”.

Rust, unwrap(), and error handling

  • Large subthread around whether using unwrap() in critical Rust code is acceptable.
    • Critics: in production, unwrap() is equivalent to an unguarded panic, hides invariants that should be expressed as Result handling, and should be linted or banned.
    • Defenders: the real problem is the violated invariant and lack of higher-level handling; replacing unwrap() with return Err(...) would still have yielded 5xxs without better design.
  • Broader debate compares Rust’s Result-style errors vs exceptions, checked vs unchecked, and how easy it is in all languages to paper over error paths.

Architecture, blast radius, and fail modes

  • Many point out this was not “just a bug” but an architectural issue:
    • A non-core feature (bot scoring) was able to crash the core proxy.
    • The system failed “fail-crash” instead of “fail-open” or “keep last-good config”.
  • Suggestions:
    • Treat rapid, global config as dangerous code: canaries, fault isolation (“cells”/regions), global kill switches with care, and strong observability on panics and config ingestion.
    • Ensure panics in modules are survivable by supervisors or by falling back to previous configs, with clear alerts.

Operational response and transparency

  • Some are impressed by how fast and detailed the public postmortem appeared, including code snippets and a candid incident timeline.
  • Others focus on the ~3 hours to identify the feature file as root cause, questioning:
    • Why massive new panics in FL2 weren’t an immediate, high-signal alert.
    • Why “it’s a DDoS” was the dominant hypothesis for so long.
  • The separate outage of the third-party status page further biased engineers toward believing it was an attack.

Centralization and systemic risk

  • Extensive reflection on how much of the internet now depends on a few providers (Cloudflare, AWS, etc.), drawing analogies to historic telco and infrastructure outages.
  • Some users report practical impact (unable to manage DNS, log into services) and reconsider reliance on a single CDN/DNS provider.
  • A minority argues for regulation and liability around critical internet infrastructure; others counter that outages are inevitable in complex systems and that learning from failures is the path to resilience.

Ford can't find mechanics for $120K: It takes math to learn a trade

Pay Levels, CEO Compensation, and the “$120K” Figure

  • Many commenters say “just pay more and train people” and note that $120k today is roughly mid‑1990s $60k, so not extraordinary.
  • Others push back that wages must remain economically viable; you can’t simply mandate $300–500k.
  • There’s heavy skepticism that Ford mechanics actually earn $120k: claims that this is a top‑end figure requiring huge overtime, flat‑rate underestimation of repair times, and ignoring tool costs. Several insist local mechanics rarely crack $100k.
  • Debate over redirecting CEO/C‑suite compensation to fund more mechanics: some argue trimming executive pay could meaningfully fund hundreds of techs; others note most CEO pay is in stock, not cash, and that dividends are a much larger outflow.
  • A side thread argues whether CEOs are overpaid versus “paid what the market bears,” with citations that CEO pay correlates weakly with firm performance and strongly with luck.

Training, Trade Schools, and Corporate Responsibility

  • Many argue Ford and similar firms should fund trade programs, apprenticeships, and community college curricula, as defense contractors historically have.
  • A community college professor says companies gutted in‑house training, pushed the burden onto underfunded schools, and now complain about skill gaps while teaching is done on decades‑old equipment.
  • Some think repayment clauses (pay back training costs if you leave early) solve the “we’ll train them and they’ll quit” fear; others say companies simply don’t invest seriously.

Education, Math Skills, and Credential Inflation

  • One camp blames “dysfunctional public education,” social promotion, and weak math basics; UCSD data on students needing remedial middle‑school math are cited.
  • Another camp notes U.S. scores are roughly comparable to Western Europe and argues the real issue is that math‑capable graduates are sorted into better‑paid fields.
  • Several criticize credential inflation: jobs that should be reachable with good high‑school math now demand expensive degrees, while employers still complain about skills.

Design, Maintainability, and Work Conditions

  • Some say Ford underestimates book repair times (especially warranty work) and designs vehicles that are difficult to service, so mechanics effectively work unpaid hours.
  • Others clarify that the $120k jobs are more like factory/automation technicians than classic dealer “grease monkey” roles, requiring higher‑level diagnostics and electronics skills.
  • Commenters suggest improving maintainability, paying for realistic labor times, providing tools, and building real promotion pipelines would attract more workers than PR about six‑figure roles.

Wider Economic and Policy Themes

  • Threads branch into wealth inequality, taxing billionaires, and whether higher top rates would meaningfully fund social promises.
  • Education funding cuts, voucher proposals, and family economic stress are cited as background drivers of weaker preparation and reduced interest in trades.
  • Overall sentiment: skill shortages are less about innate ability and more about pay, conditions, training investment, and system design.

Blender 5.0

Release Features and Technical Improvements

  • Strong enthusiasm for Blender 5.0’s feature set: proper HDR support, ACES 2.x color pipeline, node system upgrades (closures, bundles/structs, repeat/loops), SDF/volume grids, and faster, better scattering and volumetrics.
  • Geometry/shader nodes are praised as maturing into a serious graphical programming language; closures and bundles in particular excite people with PL backgrounds.
  • The revamped video sequencer and compositor integration are highlighted as potentially making Blender viable as an all‑in‑one tool, replacing workflows that used DaVinci Resolve.
  • Adaptive subdivision is welcomed but noted as Cycles‑only; some speculate about reproducing similar behavior in Eevee with geometry nodes.

Color Management, HDR, and ACES

  • Users are excited about “proper HDR” and ACES 2.0, noting ACES 1.x predated consumer HDR displays.
  • Discussion clarifies working vs display color spaces: ACES/ACEScg as wide‑gamut working spaces vs Display P3/sRGB as output spaces.
  • Benefits of wide working spaces are explained (avoiding clipping through exposure/tonemapping workflows), with cautions that conversion to display space still needs careful artistic control.
  • Some uncertainty remains around which Blender nodes (e.g., blackbody, sky) still assume linear sRGB vs using the new ACES pipeline.

AI and the Future of 3D Tools

  • One thread asks if AI will make tools like Blender obsolete for “average” projects in ~10 years.
  • Many respondents push back: AI is seen as an assistant embedded into tools, not a replacement (analogy to IDEs + coding agents).
  • Key constraints mentioned: continuity across shots, complex pipelines, limited high‑quality 3D training data, and the need for deterministic 3D models.
  • Others argue 3D may become even more central as deterministic geometry for “world models” that AI systems act upon.
  • Some frustration is expressed at AI being injected into every discussion.

Blender’s Place in the Industry and OSS Landscape

  • Several comments call Blender a standout open‑source success, comparable (within its niche) to Linux, Git, or KiCad in theirs.
  • Others caution against declaring Maya “obsolete”: large studios rely on deep Maya pipelines, plugins, and stable C/C++ SDKs; Blender’s Python‑only API and evolving interfaces are seen as limiting for massive productions.
  • Still, examples of serious productions using Blender (including award‑winning films and high‑profile anime) are cited as evidence it is “battle‑proven” at some scales, even if not yet at Pixar/Weta scale.

Desire for a “Blender of CAD”

  • A major subthread pivots to MCAD: many wish for a Blender‑quality, open‑source parametric CAD ecosystem, arguing it could disrupt Autodesk‑style licensing.
  • FreeCAD is the main candidate but elicits polarized views: some find it powerful and productive after tutorials; others describe the UX as “monitor‑punching,” with confusing workbenches, brittle modeling, and OpenCascade kernel limitations (fillets, seams, booleans).
  • Discussion goes deep into geometric kernels (Parasolid, ACIS, OpenCascade), why robust kernels are decades‑long, math‑heavy efforts, and why that’s a bigger bottleneck than UI alone.
  • Alternatives mentioned: OpenSCAD/CadQuery, Dune3D, SolveSpace, Plasticity, Onshape, and Blender add‑ons like CAD Sketcher and Bonsai.
  • Several argue that “general CAD” is the wrong target: successful tools are workflow‑ and industry‑specific (mechanical, AEC, simulation, etc.), and any FOSS effort needs a clear domain and user base, not just “a free SolidWorks.”

UX, Learning Curve, and Project Governance

  • Blender is repeatedly praised for unusually good UX for open source, especially post‑2.8; learning shortcuts is framed as essential to productivity.
  • People contrast Blender’s evolution with projects like GIMP/FreeCAD, suggesting Blender succeeded by:
    • Dogfooding via its own films,
    • Aligning with industry practices rather than being “different on principle,”
    • Having strong leadership, funding, and design/PM attention.
  • Some still find 3D creation too complex and wish “the computer would do it” (more automation/AI‑driven content), but others insist power tools must remain for precise control.

Infrastructure, Platform Support, and Donations

  • Many users are blocked by aggressive Cloudflare captcha/verification on the Blender site, with complaints that even a static release page is now hard to access.
  • Intel Mac support is dropped in 5.0, with comments that those machines were always limited by weak GPU drivers.
  • AMD ROCm/Cycles compatibility issues are raised but not resolved in the thread.
  • Multiple comments end by encouraging donations to Blender and, by analogy, to other FOSS tools (KiCad, FreeCAD) to accelerate them toward “Blender‑level” quality.

GitHub: Git operation failures

Immediate impact and behavior of the outage

  • Many users report being unable to push or pull via both HTTPS and SSH, seeing errors like “ERROR: no healthy upstream”, 500/503, and 404 on raw.githubusercontent.com.
  • Authentication often still works (SSH greeting), which confused people into debugging local keys and setups.
  • GitHub Actions and external CI (e.g., CircleCI) that depend on Git operations or actions/checkout also failed.
  • Some functionality in the web UI (editing files, creating branches) continued to work, but pipelines and deployments that fetch from GitHub broke.

Reliability concerns and perceived trend

  • Strong sentiment that GitHub reliability has degraded, with multiple incidents in recent weeks, especially around Actions.
  • Several commenters say GitHub is now one of the least reliable services they use; some claim outages feel “weekly” or at least monthly.
  • Others counter that outages are not new, and that similar or worse instability existed in GitHub’s early days and across other clouds (AWS, Azure, Cloudflare).

Centralization vs decentralization

  • The outage, plus a large Cloudflare incident earlier the same day, fuels criticism of heavy reliance on a few US-based centralized providers.
  • People note that both the web and Git are fundamentally decentralized, but real workflows have been re-centralized around GitHub as a “hub” (issues, PRs, CI, stars).
  • Radicle and similar p2p/decentralized approaches are mentioned, but some find their concepts confusing or impractical.

Alternatives and self‑hosting experiences

  • GitLab (SaaS and self‑hosted), Forgejo, Gitea, Gogs, Atlassian-hosted Git, and simple SSH-to-VPS setups are discussed.
  • Multiple reports of long-term stable self‑hosted GitLab or other setups; others report scaling pains with large monorepos and Gitaly.
  • Several people say they’ve avoided all GitHub downtime by not using GitHub at all.

Suspected causes: AI, layoffs, Azure migration, complexity

  • Some blame layoffs, cost-cutting, reduced ops headcount, and “enshittification.”
  • Others speculate about AI-generated code, AI-based reviews, or “AI vibe coding” degrading quality, while skeptics note outages predate LLMs.
  • The ongoing migration from GitHub’s own hardware to Azure is widely suspected as a risk factor.
  • A few argue that system scale and accumulated complexity outstrip teams’ ability to understand and maintain the infrastructure.

Resilience and mitigation ideas

  • Suggestions include: local or on-prem git mirrors/caches, multi-provider hosting (e.g., mirroring to GitLab), treating CI as replaceable and runnable locally, and embracing self-hosted forge + CI stacks.
  • Several emphasize that git itself remains distributed; GitHub is the single point of failure because teams have tied CI/CD, issues, and collaboration to it.

Oracle is underwater on its $300B OpenAI deal

Perception of the Oracle–OpenAI Deal

  • Many see the “$300B” plan (massive capex over years for OpenAI capacity) as irrational relative to OpenAI’s current ~$20B revenue and lack of profit.
  • Commenters stress Oracle gets little or no IP: it’s mostly buying Nvidia boxes, racking them, cooling them, and earning a modest markup.
  • Counterparty risk is a core concern: Oracle may build and finance infrastructure and then not get paid if OpenAI stumbles.
  • Others argue that as a cloud provider Oracle is “selling shovels” and could in theory re-sell GPU capacity to other AI users, but skeptics doubt there will be enough profitable demand for a 10x datacenter build-out.

AI Bubble, Overcapacity, and Money Destruction

  • Strong sentiment that AI resembles a speculative bubble, like crypto or dot-com, with huge valuations built on projections of 50–75% annual growth for years.
  • Some argue AI infra is a way to “burn off” excess money created in the last decade; others push back, noting you can destroy wealth but not the money supply.
  • There’s concern of a coming GPU glut: once subsidies and loss-leading free tiers end, demand and pricing might not sustain current capex, leaving “$300B of shovels” earning far less than expected.

Oracle’s Core Business and Survival

  • Several note Oracle’s legacy database business still “prints money” from locked-in customers; few new firms choose Oracle, but existing deployments are sticky and expensive to replace.
  • This leads to a split view: for some, Oracle is the weak link when the AI bubble bursts; for others, the DB cash cow plus Chapter 11–style restructuring means the company survives even if the AI bet fails.

Market Reaction and Valuation Debate

  • Oracle’s stock spike on the OpenAI announcement and subsequent drop are seen as classic hype-and-cooldown; tying a $300B multi-year plan to a few months of price action is viewed as flimsy.
  • Some argue “underwater” based on lost market cap is rhetorical; real judgment must wait on actual returns.
  • Thread devolves into broader arguments about shorting, “skin in the game,” bubble talk vs. actionable insight, and whether tech firms should return excess cash via dividends/buybacks rather than mega-bets.

Competition and AI Economics

  • Multiple comments suggest Google may outlast or out-execute OpenAI: it has huge profits, its own chips (TPUs), the search/crawler data pipeline, and can wait out others.
  • Others counter that LLMs are increasingly commoditized; brand and adoption (ChatGPT) may matter more than marginal model quality.
  • A major open question: can AI chat ever be profitably monetized (especially with ad models) at the compute cost levels implied by these infrastructure builds? Many commenters say this remains unclear or unlikely at present.

A surprise with how '#!' handles its program argument in practice

How shebangs are handled (kernel vs shell, PATH, relatives)

  • Most comments reiterate that the kernel handles #!, not the shell: on execve("/path/script", ...) the kernel inspects the first bytes; #! triggers script handling.
  • The kernel does not do $PATH lookup for the interpreter: #!bash would be treated as ./bash, not $(which bash).
  • zsh has extra logic: when execve returns ENOEXEC or ENOENT, zsh inspects the file, parses #!, and itself resolves the interpreter via its own path lookup, which is why #!bash appears to “work” only in zsh.
  • Other exec* functions and system() in libc do perform $PATH lookup for the program itself, but that is separate from how the interpreter path on the shebang is resolved.

Portability and recommended shebang forms

  • #!/usr/bin/env bash is widely advocated as the most practically portable way to get “whatever bash is in PATH”, and works on NixOS and many nonstandard layouts.
  • #!bash is rejected as non-portable and often simply broken (works only in zsh, and only in specific situations).
  • Some argue anything other than #!/usr/bin/env bash will eventually fail somewhere; others note even this assumes /usr/bin/env exists and $PATH is sane.
  • Discussion clarifies that /bin/sh, /usr/bin/env, #! itself, and env -S are conventions, not POSIX requirements, though they are ubiquitous in practice.

Security considerations

  • Several commenters see no new security issue: making a script executable already grants it arbitrary power.
  • Others point out path-based risks: #!/usr/bin/env can hit a malicious binary earlier in $PATH; relative interpreters (e.g. #!venv/bin/python3) can behave unexpectedly if directory layout changes.
  • Consensus: relative interpreters and env introduce familiar PATH risks, but nothing fundamentally new or special to shebangs.

OS quirks, limits, and nested interpreters

  • Linux supports “nested interpreters” (an interpreter that is itself a script with its own #!); OpenBSD does not.
  • FreeBSD historically allowed multi-argument/oneline shebangs, later restricted; env -S is cited as a non-portable workaround.
  • There’s a 256‑byte implementation limit on shebang length.

Practical workflows and annoyances

  • NixOS users lean on #!/usr/bin/env and Nix shebangs, given nonstandard paths.
  • Some Python users deliberately use relative shebangs into venv/bin/python3 to avoid activation, trading flexibility for explicit project-local environments.
  • BOM-prefixed UTF‑8 files break shebang parsing, causing confusing “bad interpreter” errors.

I am stepping down as the CEO of Mastodon

Background and the “last summer” incident

  • Commenters ask what “particularly bad interaction” pushed the CEO to step back.
  • Various public controversies are mentioned (user flamewar, Twitter fight, security issue, ActivityPub vs Bluesky spat), but the CEO clarifies it was a non‑public incident unrelated to those.
  • Some see this as another example of how abusive or entitled users can burn out community leaders.

Leadership change, governance, and finances

  • Many view transition away from dependence on a single founder as healthy, analogous to the web moving beyond its inventor.
  • Others worry about a potential “committee” slowdown, but some note that nonprofits routinely operate with boards and an executive director.
  • The €1M one‑time compensation for the founder sparks debate:
    • Supporters see it as fair payment for years of under‑market salary and IP transfer.
    • Thread dives into EU/German tax treatment and whether €1M is enough to retire, with wide disagreement.

Fediverse vision vs “capitalist hellscape”

  • The quoted line about the fediverse as an “island within an increasingly dystopian capitalist hellscape” divides opinions:
    • Supporters say it accurately reflects data‑driven addiction and algorithmic outrage on mainstream platforms.
    • Critics call it extreme, argue “capitalism” is being used as a pejorative without clear alternatives, and point to popular centralized services like Discord.

Culture, moderation, and toxicity

  • Some praise Mastodon as calmer, ad‑free, and largely free of bots/influencers; others describe it as fragmented, drama‑prone, and ideologically rigid (often characterized as “authoritarian left”).
  • Several report harsh pile‑ons or bans over politics or even URL tracking parameters, and say that muting isn’t enough to escape the prevailing culture on some instances.
  • Others counter that experience depends heavily on instance and follows; they compare Mastodon’s problems to all large social networks and argue moderation freedom is a feature of federation.

Size, growth, and UX

  • Mixed feelings about growth:
    • Some want more users and better discoverability; others think low population is precisely why it feels livable.
  • Onboarding is widely seen as confusing, especially server choice; some users report “choice paralysis” and leaving.
  • Discoverability criticisms: hard to find people/topics across instances; no equivalent to Bluesky “starter packs”, though there’s an open proposal for similar “featured collections”.
  • Defenders argue email‑like addressing and hashtag follows make the model understandable and powerful once you invest effort.

Technical and architectural debates

  • Long‑running anger over Mastodon’s link‑preview implementation, which causes many instances to independently fetch the same URL, is described as an “intentional DDoS” of small sites.
    • Critics blame the founder for years of resisting a design where preview metadata is bundled with the post.
    • Others frame his responses as prudent gatekeeping given limited dev time and subtle trade‑offs.
  • Quote‑tweet support is cited as another case where the founder’s earlier refusal (“leads to toxicity”) frustrated some developers; it has since been added, influenced by Bluesky’s more nuanced model.
  • Comparisons with ActivityPub vs ATProto:
    • Some say ATProto has better UX and handle portability but is effectively centralized and schema‑heavy.
    • ActivityPub is seen as more flexible but messy and under‑coordinated.

Decentralization, identity, and legal risk

  • Several argue Mastodon’s decentralization is limited: you still depend on server admins who can ban you, and domains/TLS roots are central points of control.
  • Others reply that true decentralization means choice of overlord (including running your own instance), which is still better than a single corporate owner.
  • Self‑hosting raises concerns about legal liability: operators may be responsible for federated content and privacy‑law compliance, especially for one‑person instances.
  • Nostr and other models (key‑based identity, “relay” networks, lighter servers like GoToSocial) are mentioned as alternatives that might better match a “node among equals” ideal.

Broader reflections on social media and community

  • Many tie the founder’s burnout to a wider pattern: moderating or leading large online communities has become emotionally brutal, even with strong ideals.
  • Several see microblogging culture (Mastodon, Bluesky, X) as uniquely flat, outrage‑oriented, and lacking the “local bar” community feeling of old forums; others say Mastodon feels much closer to that older internet than corporate feeds do.
  • HN itself is used as both a positive and negative point of comparison: well‑moderated but heavily filtered; evidence that open discussion spaces struggle with outrage, pile‑ons, and “bad behavior as cancer.”

Future of Mastodon and the non‑profit structure

  • The new structure involves:
    • A German entity that lost charitable status and now functions as a for‑profit for operations.
    • A US 501(c)(3) to accept tax‑deductible donations and temporarily hold trademarks/assets.
    • A planned Belgian AISBL nonprofit to ultimately own the brand and coordinate globally.
  • Some praise the transfer of trademarks and assets to a non‑profit as exemplary in contrast to other OSS governance crises.
  • Others worry about big‑name board members and potential drift, but there’s general hope that the project can outlive its founder, especially with him staying in an advisory and technical role.

Pebble, Rebble, and a path forward

Overview of the Dispute

  • Thread responds to two posts: Rebble accusing Core of “stealing our work” and Core’s rebuttal laying out its side.
  • Most commenters see a classic mutual-trust breakdown: both sides think the other can jeopardize the ecosystem and feel existentially threatened.

Ownership and Access to App Store Data

  • Central conflict: the Pebble/Rebble app store archive.
  • Rebble:
    • Scraped and rebuilt the original Pebble app store, patched hundreds of apps, added new ones, and runs paid services (weather, voice-to-text).
    • Fears Core will ingest this data, build its own closed store, lock Rebble out, and leave them with “less than they started with” if Core fails.
  • Core:
    • Argues the app data came from thousands of independent developers and “should not be controlled by one organization.”
    • Offers to pay Rebble per user and keep using Rebble-hosted services but wants freedom to build competing features and avoid dependency on a third party.

Open Source, Licensing, and Nonprofit Status

  • PebbleOS is now Apache-2.0; many see this as strong protection against future lock-in.
  • Several argue that building a business on open source + scraped data inherently risks being superseded.
  • Debate over Rebble’s “nonprofit” status (state-level, not 501(c)(3)); some find their nonprofit branding potentially misleading, others say it’s irrelevant if they’re not soliciting tax-deductible donations.

Scraping Allegations and Conduct

  • Rebble says Core violated a no-scraping agreement; Core says it only used a tool to visually review watchfaces, not archive binaries.
  • Long subthread on what “scraping” means and whether intent or storage matters.
  • Many criticize Rebble for objecting to scraping when their own archive began as scraping the original Pebble store.
  • Publishing private chat screenshots without consent is widely viewed as a bad look for Core.

Trust, Sustainability, and User Reactions

  • Some default trust to the original hardware founder; others to the long-running community maintainers.
  • Concerns that:
    • Core could repeat Pebble’s original failure or “enshittify” later.
    • Rebble is acting like a gatekeeper/rent-seeker rather than a neutral steward.
  • Several users cancel preorders; others say they’re still excited and grateful for new hardware.

Proposed Paths Forward

  • Legal guarantees that any Core app store remains open and accessible to third parties.
  • Dual stores: Core for new/actively maintained apps, Rebble as an archival “classic” catalog.
  • Stronger copyleft licensing and/or moving governance to a neutral OSS foundation.
  • General sentiment: both sides are hurting the ecosystem; users want guarantees that devices, apps, and data remain usable if either party disappears.

Disney Lost Roger Rabbit

Overall reaction to the article

  • Many readers found it clear, enjoyable, and an effective explanation of how copyright has drifted from its stated purpose, especially around creative labor and media monopolies.
  • Others thought Doctorow’s rhetoric overstated powerlessness (“forced” contracts, “no alternatives”) and disliked some analogies as misleading or overly class-framed.

Termination of Transfer and creator leverage

  • Strong support for 35‑year “Termination of Transfer” as one of the few copyright tools that clearly benefits creators, since it can’t be permanently signed away.
  • Counterpoint: waiting 35 years feels like “half a lifetime” and more like a symbolic fix; suggestions ranged from ~10–20 years or back to the original 14+14 model.
  • Some argue termination probably doesn’t dramatically lower upfront payments, since the NPV of income after 35 years is tiny and companies work around it with bundled deals.

Roger Rabbit specifics and limits

  • Excitement that the original author regained rights; some hope for a new “Roger Rabbit universe.”
  • Several point out legal and practical constraints:
    • Disney (and others) almost certainly own the movie character designs and specific visual incarnations.
    • Spielberg reportedly must approve any new Roger content.
    • The film was a multi‑studio “lightning in a bottle” collaboration unlikely to be replicated.
  • Some note the novel and film differ heavily; even with rights back, the author may only freely exploit the book’s incarnation, not Disney’s.

Other IP control examples & “ashcan” works

  • Dick Tracy, Star Wars merchandising, Wheel of Time, Fantastic Four (1994), Universal’s Marvel land: all cited as examples of rights being hoarded or minimally exercised (“ashcan” / “placeholder” productions) just to preserve control.
  • Debate over whether this behavior is rational IP stewardship or just petty gatekeeping that harms audiences and creators.

Abandonware and games

  • Question raised whether old game developers could reclaim rights; general answer: only if they weren’t work‑for‑hire and held the original copyright.
  • Japan’s government licensing mechanism for reissuing abandonware (with escrowed royalties) cited as an alternative model.

Market power, alternatives, and self‑publishing

  • Doctorow’s monopsony framing (5 publishers, 4 studios, etc.) resonated with many, including for app stores.
  • Critics respond that creators aren’t literally forced: they can shop around or self‑publish, and some have succeeded that way—though others argue the alternatives are often weak and discoverability is still dominated by a few platforms.

Copyright scope, term, and philosophy

  • Calls ranged from modest shortening (e.g., fixed 50 years) to drastic cuts (~10 years) or returning to 14+14 with renewal reserved to creators.
  • Disagreement over whether shorter terms would boost or reduce investment in new works, and whether consolidation would worsen or improve.
  • Several note that current ultra‑long terms mainly benefit large catalog owners, not working creators, and also restrict new creators’ ability to draw on the cultural commons.

AI, media cartels, and creators

  • Some see media lawsuits against AI firms as primarily rent‑seeking: big publishers want to own a new “AI training right” and then sell it to AI companies, further marginalizing artists.
  • Others hope large rights holders might, even inadvertently, establish legal precedents that protect all creators from unlicensed training.
  • Separate debate highlights that entertainment conglomerates are currently a bigger, more concrete threat to creators than AI, though generative AI may exacerbate discoverability problems and flood markets with standardized “slop.”

Nature of IP and rights alienation

  • Ongoing thread on whether copyright should be alienable like physical property, or more like an inalienable “author’s right” (with only usage licensed), as in some civil‑law countries.
  • Some argue creators should never be able to fully sign away core rights, to prevent systematic exploitation; others insist transferability is essential to financing and exploiting works at scale.

`satisfies` is my favorite TypeScript keyword (2024)

TypeScript’s learning curve and skill gap

  • Many commenters agree TypeScript is deep and “esoteric” at the high end, with a huge gap between everyday users and type‑system experts.
  • Most production codebases reportedly use only the basics (type, interface, unions, simple generics). Advanced constructs (recursive conditional types, complex utility types) are mainly seen in libraries.
  • Some see this as a strength: “application TS” benefits from simple types, while “library TS” justifies advanced tricks. Others feel it exposes a serious lack of type‑theory understanding among working devs.

Advanced types vs maintainability

  • There’s a long back‑and‑forth about complex type definitions (e.g., perfectly typing Array.prototype.flat).
  • One camp says these signatures are critical for accurate APIs and a great user experience, especially for libraries, and that professionals should handle the complexity.
  • The opposing camp views such types as “character soup” that few can understand or safely maintain; better to restructure data and avoid hyper‑dynamic APIs than to do “type gymnastics”.
  • Several people explicitly prefer simplifying JS structures over pushing the TS type system to its limits.

What satisfies actually buys you

  • Multiple explanations converge: satisfies checks that a value is assignable to a type while preserving the original, more precise inferred type.
  • Compared with:
    • : Type — enforces the type but broadens inference (e.g., "foo"string) and may reject extra fields.
    • as Type — coerces and can hide mistakes.
    • as const — narrows but doesn’t validate against a separate interface.
  • Common use cases mentioned:
    • Objects that must conform to an interface but can have extra properties.
    • Safer conversions between related types.
    • Exhaustiveness checking in switch (e.g., myFoo satisfies never in default).
    • “Typetest” files for libraries and checking schema libraries (like Zod) against TS interfaces.

Static typing, soundness, and alternatives

  • Several comments note that TypeScript is intentionally unsound; type errors proven impossible at compile time can still occur at runtime, especially when escape hatches or third‑party code are involved.
  • Some see TS primarily as pragmatic tooling (autocomplete, refactors, catching parameter mismatches). Others want stronger guarantees and lean on runtime validators.
  • Alternatives like ReScript and Go are cited as having simpler, sounder or stricter approaches; some wish TS hadn’t inherited so much dynamic JS flexibility.

How long can it take to become a US citizen?

Backlogs and human impact

  • Several comments highlight that US immigration is so backlogged that many family-sponsored applicants die before getting green cards; waits of decades are common.
  • Long-term employment-based applicants live in “limbo,” tied to employer whims and at risk of losing everything in a downturn, with some couples needing 20–30 combined years to reach citizenship.

Is citizenship / immigration a right?

  • One side argues citizenship is not a right and sovereign nations can set steep requirements and caps.
  • Others counter that birthright citizenship is a constitutional right, and that decades-long bureaucratic limbo is abusive.
  • Some say in the long run borders themselves may lose moral legitimacy; others press for a strong right of national self‑determination.

Birthright citizenship and constitutional disputes

  • Discussion centers on the 14th Amendment’s “subject to the jurisdiction thereof.”
  • Multiple commenters stress that an executive order cannot override the Constitution, and current attempts to limit birthright citizenship are blocked in court.
  • Others warn that Supreme Court reinterpretation (e.g., reversing Wong Kim Ark) is possible, which could create a class of US‑born non‑citizens with few protections.

Economics: labor, wages, and business incentives

  • One view: the US depends on immigrant labor; removing undocumented workers would cripple sectors like agriculture and housing.
  • Counterview: there’s no real skills shortage; employers use immigration (and H‑1B–style visas) to suppress wages instead of investing in domestic workers and social supports.
  • Some say big business wants large inflows but prefers immigrants without rights (easier to exploit and blame).

Culture, diversity, and demographics

  • Dispute over whether immigration prevents “cultural stagnation” or erodes existing cultural identities and social cohesion.
  • Some defend per‑country caps as consciously designed to promote global diversity rather than letting populous countries dominate flows.
  • Others see this as unfair to India/China/Mexico/Philippines and note that huge internal diversity within those countries is ignored.
  • Long exchanges debate whether cultures are equal, whether immigrant cultures persist over generations, and whether demographic change threatens “national identity.”

Law, morality, and enforcement

  • “Just do it the right way” is criticized as moralistic when the legal path is often practically impossible or racially rooted.
  • Others insist that no one has a human right to immigrate; laws may be harsh but should be enforced until democratically changed.
  • Sanctuary policies are framed either as anti‑democratic nullification or as legitimate 10th‑Amendment limits on federal power.
  • Concerns raised about current enforcement practices: lack of due process, racial profiling, and ICE ignoring evidence of citizenship.

Fairness and access

  • Commenters note how hard the system is for “honest, hard‑working” people versus how relatively easy it can be for the wealthy to buy access via investment routes.
  • Some non‑US examples (Germany, other EU states) show similarly dysfunctional systems that import needed workers, then force them out on technicalities.

Google Antigravity

What Antigravity Actually Is

  • Widely recognized as a minimally customized fork of VS Code / Electron, with an “agents” pane and Gemini integration layered on.
  • Website and blog largely avoid saying “VS Code”; some see that as disrespectful to the upstream work.
  • Supports multiple models (Gemini 3 Pro high/low, Claude Sonnet 4.5, GPT-OSS 120B), not just Gemini.

VS Code Fork Explosion

  • Many see this as “yet another AI IDE that’s just VS Code,” alongside Cursor, Windsurf, Lovable, etc.
  • Debate over why these aren’t just extensions:
    • One side: Microsoft gatekeeps deeper APIs for Copilot; forks allow tighter integration and avoidance of MS control.
    • Other side: fragmentation is needless; a common “AI-enabled” fork or open interfaces would be better.
  • Some praise truly original editors like Zed or JetBrains IDEs as higher-quality alternatives.

Launch Quality & UX Issues

  • Numerous reports of:
    • Blank page or MIME-type errors in Firefox; broken/mobile scrolling that feels “nauseating.”
    • Mac and Linux startup failures, crashes, and extreme slowness; fans spinning hard.
    • “Setting up your account” spinner that never completes, especially for Workspace accounts.
  • Website criticized for:
    • Almost no product screenshots at first, heavy marketing language, and odd scroll hijacking.

Trust, Longevity & Lock‑in

  • Strong skepticism about investing in a Google IDE due to the company’s history of killing products and internal incentives favoring launches over maintenance.
  • Concerns about:
    • Account bans locking users out of tools.
    • Data collection/telemetry and training on user code (especially for free tiers).
    • No Vertex / enterprise integration yet; Workspace accounts initially unsupported.
  • Some expect Antigravity to be short-lived or primarily a promotion vehicle.

“Agentic Development” Reactions

  • Marketing pitch: developers become “managers of agents,” focusing on architecture and tasks, not implementation.
  • Many engineers find this framing unappealing or dystopian; likened to low/no‑code hype:
    • Real bottleneck is specifying requirements and handling edge cases, not just cranking out code.
    • Fear of future systems where nobody understands the codebase, cruft explodes, and agents continually patch over issues.
  • Others argue agents can:
    • Summarize architectures, explain code, and accelerate onboarding.
    • Automate GUI testing via browser control, a genuine pain point.

Pricing, Quotas & Access

  • Free “generous” preview limits felt extremely tight:
    • Users hit “model quota exceeded” or “provider overload” after minutes or a couple of prompts, often on first real task.
    • Confusing error messages (quota vs global overload) and no clear path to pay for higher limits or BYO API keys.
  • This undermines confidence and makes it hard to evaluate Gemini 3 Pro inside the IDE.

Comparisons to Existing Tools

  • Frequent comparisons to:
    • Cursor / Codex / Claude Code / Opencode, where many already have stable workflows.
    • Firebase Studio, IDX, Jules, Gemini CLI—other overlapping Google efforts.
  • Some feel Antigravity adds a useful centralized Agent Manager (multi‑workspace, task inbox, inline comments routed to agents).
  • Others see no compelling advantage over “VS Code + Claude/Codex/Gemini via plugins or CLI.”

Branding, Hype & Tone

  • “Antigravity” name seen as overblown, misleading, or an xkcd in‑joke; five syllables considered clumsy.
  • “Agentic” has become a buzzword that many find grating; marketing copy about “trust” and “new eras” read as hype‑driven.
  • Several note the blog focuses on Google’s vision and internal narrative rather than concrete user benefits.

Early Hands‑On Impressions

  • Positive:
    • Some users genuinely like the workflow: plan docs, inline comments, browser automation, and unified Agent Manager make multi-agent work more coherent.
    • Tab completion and UI for iterating on a plan are praised by a subset of testers.
  • Negative:
    • Others report Gemini 3 performing worse than Claude or GPT-based tools on real tasks, going off on tangents or declaring tasks “done” when they aren’t.
    • Bugs (rate limits, crashes, broken Vim mode, odd windows, MCP issues) make it feel like a rushed, “vibe‑coded” beta.
  • Overall sentiment: interesting ideas, but marred by execution problems, unclear quotas, and deep distrust of Google’s long‑term commitment.

Gemini 3

Rollout, Access & Tooling

  • Early in the thread many saw “confidential” labels, hard rate limits, and “quota exceeded” errors even though Gemini 3 appeared in AI Studio, Vertex, and APIs. Some reported it quietly working in Canvas with “2.5” before the official flip.
  • Gemini 3 Pro shows up as “Thinking” on gemini.google.com, with a low/high “thinking level” option; preview models also exposed via Vertex and API (gemini-3-pro-preview), and via GitHub Copilot / Cursor.
  • CLI access is gated by a waitlist; multiple people struggled to understand how Gemini One/Pro/Ultra, Workspace, AI Studio “paid API keys,” and CLI entitlements tie together.
  • Antigravity and AI Studio apps impressed some (browser control, app builder, 3D demos) but others hit server errors, missing features, and awkward Google Drive permission prompts.

Pricing & Product Positioning

  • API prices rose ~60% for input and ~20% for output vs Gemini 2.5 Pro; long-context (>200k) remains pricier. Some see this as acceptable if fewer prompts are needed; others worry about squeezed margins for app builders.
  • Grounded search pricing changed from per-prompt to per-search; unclear net effect.
  • Comparisons: still cheaper than Claude Sonnet 4.5; well below Claude Opus pricing. Several note Google’s strategy of bundling Gemini with Google One / Android to drive adoption.
  • Marketing claims like “AI Overviews now have 2 billion users” drew skepticism, with people arguing “user == saw the box” rather than opted-in usage.

Benchmarks vs Reality

  • Official charts show strong gains on ARC-AGI (1 & 2), NYT Connections, and other reasoning benchmarks, sometimes beating GPT‑5.1 and Claude Sonnet 4.5. Some suspect “benchmaxxing” or contamination of public eval sets.
  • Multiple commenters emphasize private, task-specific benchmarks (coding, math, law, medicine, CAD). Experiences conflict: some see Gemini 3 as clear SOTA; others find older models or Claude/OpenAI still better for their niche.

Coding & Agentic Behavior

  • For many, Gemini 3 Pro is a big step up from 2.5 in complex coding, refactors, math-heavy code, CAD (e.g., Blender/OpenSCAD scripts), and UI design; a few report one-shot fixes where others failed.
  • Others find it weaker than Claude Code or GPT‑5‑Codex for “agentic” workflows: poor instruction following, over-engineered or messy code, hallucinated imports, partial fixes, or ignoring “plan first” instructions. Gemini CLI itself is viewed as buggy and UX‑rough.
  • Long-context coding remains mixed: some praise project‑scale reasoning; others say Gemini still misapplies edits and forgets constraints, similar to 2.5.

Multimodal, SVG & Audio

  • The “pelican riding a bicycle” SVG test and many variant prompts (giraffe in a Ferrari, goblin animations, 3D scenes) show much better spatial understanding than previous models; people note genuine generalization, not just that one meme.
  • Vision is still brittle: it miscounts legs on edited animals and misses extra fingers; commenters attribute this to perception and tokenization limits, and possibly guardrails around sensitive regions.
  • Audio performance is polarized: some see huge improvements in meeting summaries with accurate speaker labeling; others get heavy hallucinations, wrong timestamps, and paraphrased “transcripts” on long podcasts.

Privacy, Data & Trust

  • A leaked/archived model card line about using “user data” from Google products for training triggered fears about Gmail/Drive being in the training set; others point to ToS/privacy carve‑outs and doubt bulk Gmail training, but trust is low.
  • Broader unease persists about surveillance capitalism, ad‑driven incentives, and AI Overviews cannibalizing the open web’s incentive to create content.

Ecosystem, Competition & Impact

  • Many see Google “waking up” and possibly retaking the lead from OpenAI/Anthropic on reasoning while leveraging its distribution (Search, Android, Workspace). Others warn that product quality, not just raw models, will decide winners.
  • There’s noticeable AI fatigue: people rely on their own tasks as the “real benchmark” and are skeptical of hype. Some worry about job erosion and over‑reliance on LLMs; others see this as just another productivity tool wave akin to IDEs or outsourcing.

Show HN: Browser-based interactive 3D Three-Body problem simulator

Inspiration and Overall Reception

  • Many commenters praise the simulator as “lovely,” “beautiful,” and surprisingly smooth for a browser app, with particular appreciation for the 3D presets and rich controls.
  • The URL and concept are explicitly tied to the “Three-Body Problem” novels; several people connect the sim to moments in the books or TV show, with mixed opinions on the accuracy/quality of the fiction.
  • Some plan to let kids play with it or use it as an educational tool.

Implementation, Integrators, and Performance

  • The sim uses Newtonian gravity with selectable ODE solvers (Velocity Verlet, RK4). Defaults are fixed time steps plus a “softening” factor to avoid singularities when bodies get very close.
  • Discussion suggests adding adaptive step sizes and symplectic integrators for long‑term accuracy; links are shared to academic references and other 2D/3D n‑body demos.
  • Suggestions include:
    • Presets for real systems (e.g., Alpha Centauri, Earth–Moon–Sun, Painlevé configuration).
    • Visualizations of total momentum and escape energy.
    • A perturb button (currently achievable by pausing and tweaking mass/positions).
    • Handling close approaches via merging/tearing bodies, rather than letting forces explode.
  • Implementation details like using Three.js Line2 for thick trails, potential web workers, and an anaglyph (red/cyan) 3D mode are discussed; the author rapidly fixes small bugs (camera lock after pause, anaglyph behavior).

Chaos, Stability, and Physics Discussion

  • Several comments clarify that:
    • Three‑body systems are deterministic but chaotic: highly sensitive to initial conditions, no general closed‑form solution.
    • There are special periodic orbits; these can appear stable for a while but often are unstable to perturbations. The demo’s initial “stable” configuration eventually diverges due to numerical error.
    • Sundman’s analytical series solution exists but converges so slowly it’s useless in practice.
    • Numerical solvers with finite precision necessarily diverge from the “true” trajectory over time.
  • Debate arises over “stability” in real systems (e.g., Earth–Moon–Sun, moons, Lagrange points, KAM theorem), and over misconceptions connecting n‑body ejections with the Big Bang.
  • Users note how frequently bodies are ejected in the sim and how it reveals intuitions like: after a slingshot, the remaining binary’s barycenter itself moves through space.

LLMs and “Vibecoding”

  • One thread asks if this was “made with Gemini 3.” Responses note that the physics are standard numerical ODE integration, but the code can be “vibe‑coded” with LLMs.
  • The author confirms using Claude Code to bootstrap the project, then refining it.
  • Others reference Google’s Gemini 3 demo of a three‑body simulation UI.

Short Little Difficult Books

Attitudes Toward “Difficult” Books

  • Some readers embrace difficulty as a kind of intellectual “Dark Souls” hobby; others insist they read fiction for fun and reject any implied moral superiority in preferring hard books.
  • Several note the article caricatures people who dismiss difficult books as “fraudulent” or “pretentious,” and argue that criticism is aimed at anti‑intellectual sneering, not at casual readers.
  • Others observe that many “difficult” books don’t feel hard once you’re attuned to their style; the main friction is often length, required attention, or confusing plots.

Moby‑Dick and Reading at the Wrong Age

  • Multiple commenters love Moby‑Dick, especially its humor and digressive whale lore, and recommend shorter Melville (“Billy Budd,” “Bartleby,” “Typee,” “Omoo”) as on‑ramps.
  • Several recount hating it (or plays like A Raisin in the Sun, Shakespeare, Gatsby, Animal Farm) when forced in school, then finding them profound or funny as adults.
  • Debate over curriculum: some argue teens lack the historical or emotional context for certain classics; others respond that allegory (e.g., Animal Farm) is precisely how context is built.

Specific “Short, Difficult” Fiction

  • Enthusiastic, mixed, and hostile takes on:
    • Blood Meridian: for some, a gory, nihilistic but page‑turning contender for “Great American Novel”; for others, needlessly obscure or just horrifying.
    • The Road, Blindness, Death with Interruptions, The Queue: initially disorienting forms (sparse punctuation, unattributed dialogue, long paragraphs) that become immersive.
    • Ionesco’s short plays, Banks’s Feersum Endjinn, Calvino, Philip K. Dick, Borges, Delillo, Pynchon, DFW, Ballard, Nabokov’s Pale Fire, Gene Wolfe, Queneau’s Exercises in Style as rich, often playful difficulty.

Finnegans Wake and Experimental Prose

  • On Finnegans Wake, advice includes: nothing “prepares” you; just submit to it, treat it as poetry, or listen aloud.
  • Some recommend a brief guide or “skeleton key” only after a first pass, to preserve pleasure rather than turn it into thesis work.

Language, Age, and Non‑Fiction Difficulty

  • Readers highlight “old” versions of modern languages (Rabelais, La Chanson de Roland, Chaucer, Shakespeare, Don Quixote in Spanish, Old/Ancient Greek) as a separate, rewarding kind of difficulty.
  • Others propose short, dense non‑fiction as analogues: Landau’s physics, Soviet Mir handbooks, Rudin’s analysis text, primary historical/philosophical sources, and social‑science works.
  • One notes Cal Newport–style strategies: use secondary sources to ease into hard primary texts.

Reading Strategies and Media

  • Audiobooks are praised for carrying readers through dense prose like Blood Meridian.
  • Some describe “training” on difficult literature over years, finding once‑impenetrable books suddenly accessible and enjoyable.

Nearly all UK drivers say headlights are too bright

Regulations, loopholes, and weak enforcement

  • Multiple commenters note that headlight brightness and placement are regulated in the US, UK and EU, but rules are outdated (e.g., wattage limits written for halogens) and easy to game.
  • Modern LED systems can be engineered with a dim “measurement spot” while over-illuminating the rest of the field.
  • Enforcement is patchy: many US states have no real safety inspection; others barely check aim. EU/UK MOT-style tests are stricter but still miss a lot in practice.
  • There is broad support for tighter rules on maximum brightness, color temperature, and especially headlight height, plus stricter control of retrofit LED/HID kits.

Why glare feels worse now

  • LEDs and HIDs are brighter, whiter/bluer, and more point-like than old halogens, creating harsher glare and more perceived brightness for the same lumens.
  • Rising vehicle heights (SUVs, pickups, lifted trucks) put low beams at or above the eye level of drivers in normal cars and of pedestrians and cyclists.
  • Misalignment is widespread: factory mis-aim, owner ignorance of leveling controls, suspension changes, and illegal retrofits into halogen reflectors all spill light into oncoming eyes.
  • Auto high-beam and matrix systems often react late, don’t detect bikes/pedestrians, and can still hit drivers or walkers with full intensity over hills and around bends.
  • Aging eyes, cataracts and astigmatism make the new light profiles especially debilitating for many.

Safety tradeoffs and disagreement

  • One camp says brighter lights are vital on dark rural roads with no markings, wildlife, potholes, and pedestrians in dark clothes; they argue high beams and strong low beams are genuinely needed.
  • The opposing camp argues that modern low beams already approach or exceed old high-beam brightness, destroy night adaptation, and make others more likely to crash; they see speed reduction as the correct response, not more lumens.
  • Several note that sharp beam cutoffs plus extreme brightness can actually reduce useful visibility off to the sides and beyond the cutoff.

Other lighting offenders

  • Over-bright LED brake lights, taillights, animated indicators, strobing bicycle lights, emergency vehicles, and LED billboards all contribute to “HD daylight at night” and lost night vision.
  • Some drivers and cyclists adopt countermeasures (amber/yellow glasses, anti-glare mirrors, manually dimmed screens), but others see these as coping with a systemic design and regulatory failure rather than a solution.

Experiment: Making TypeScript immutable-by-default

Mechanisms for immutability in TypeScript/JS

  • Several comments suggest using a TypeScript compiler plugin (e.g. via ts-patch) to add a preprocessing step that rewrites object types as readonly, enforcing immutability by default at type-check time.
  • Others point out existing tools:
    • Object.freeze() plus TypeScript’s typings gives compile‑time errors on mutation; as const achieves similar behavior without runtime calls.
    • Critique: these are opt‑in and usually shallow; they don’t satisfy the “immutable by default” goal and don’t prevent all object mutations.
  • There’s interest in using property setter tricks and conditional types, but skepticism that current TS primitives (object, {}) are flexible enough to redefine default behavior.
  • Some rely on runtime deep cloning (e.g. structuredClone / JSON.parse(JSON.stringify(...))), but this is acknowledged as slow and partial.

Loops, variables, and style

  • Clarification: the experiment targets immutable objects, not banning variable reassignment (const vs let is mostly solved already).
  • For loops in an immutable style, commenters recommend for..of, map/filter/reduce, entries() and higher‑order functions; traditional index‑mutation loops are seen as less suitable.
  • One view: for loops are largely redundant if collections have good map/forEach; others push back that forEach is not meaningfully “more functional” and control flow differences matter.

Alternative languages vs tightening TypeScript

  • Some argue it’s simpler to choose a language that’s immutable‑first or compiles to JS with strong guarantees (Gleam, ReScript/Reason, Scala.js, ClojureScript, Elm, etc.).
  • Counterpoint: TypeScript’s ecosystem, JS interop, hiring pool, and gradual‑adoption story make “stricter TS” more realistic for most teams than a wholesale language switch.

Immutability: benefits, costs, and performance

  • Strong pro‑immutability camp: easier reasoning, safer concurrency, better state management and testing, fewer classes of bugs; default immutability in languages like Clojure/Haskell is described as a “superpower.”
  • Skeptical camp: in JS/TS, immutability is bolted on, often via cloning and spread, which can hurt performance (more allocations, GC pressure, O(N²+) patterns when chaining map/filter).
  • One detailed account from a large TS codebase notes real production regressions from Redux‑style cloning of large state trees; argues that in JS, immutability vs performance is a genuine trade‑off, not a free win.
  • Others respond that mutation’s only advantage is performance; ideally runtimes should make persistent immutable structures fast so the trade‑off mostly disappears, but acknowledge that JS doesn’t have this natively today.

Persistent data structures and equality

  • Multiple comments stress that “effective immutability” requires persistent data structures with structural sharing; otherwise naive copying will “grind to a halt.”
  • Comparisons are made to Clojure’s and Immutable.js’s persistent collections; JS’s freeze/seal/readonly are framed as shallow, local restrictions, not full structural immutability.
  • For full benefits (e.g. cheap equality checks, React optimizations), commenters want value‑based equality and language‑level constructs like the abandoned Records & Tuples proposal or the newer Composites proposal.
  • In the TS world, libraries like fp-ts and effect-ts are cited as ecosystems that try to bring persistent and functional patterns, though they add complexity and are seen by some as “bolt‑ons.”

Terminology and ergonomics

  • Some prefer “read‑write/read‑only” over “mutable/immutable,” but others argue those terms conflate capability with access permissions; immutability implies no one can change the value, not just “you can’t.”
  • A few TS users note that pervasive readonly/deep‑readonly types tend to “infect” a codebase, requiring lots of annotations and boilerplate, which is exactly what an immutable‑by‑default mode aims to reduce.

Do not put your site behind Cloudflare if you don't need to

Cloudflare as single point of failure vs overall reliability

  • Many argue that putting a small site behind Cloudflare reduces technical single points of failure: global anycast, CDN, WAF, tunnels, etc.
  • Others say it simply shifts the SPOF to a single company: its culture, policies and mistakes can take down large chunks of the web at once.
  • Several note it’s often easier to tell management “half the internet is down” than to explain bespoke infra failure; outages are socially easier to defend.
  • Uptime math comes up: rare multi‑hour Cloudflare outages still yield very high annual availability; for most small sites that’s acceptable.

DDoS, bots, and risk for small sites

  • One camp: tiny blogs don’t need DDoS protection; if they’re down or attacked, impact is negligible and you can “turn Cloudflare on later.”
  • Counter‑camp: DDoS‑as‑a‑service is cheap; even personal blogs and forums have been targeted, leading to hosts null‑routing or terminating accounts and/or surprise bandwidth bills.
  • Multiple anecdotes describe constant bot and AI‑scraper load making even low‑traffic PHP/WordPress or forums unsustainable without caching/CDN.

Centralization, privacy, and censorship concerns

  • Strong worry about Cloudflare as a de‑facto private intranet and internet gatekeeper: MITM TLS termination, traffic logging, cooperation with governments, and shareholder incentives.
  • Concerns about governments or ISPs blocking Cloudflare IP ranges (e.g., sports piracy crackdowns), making many unrelated sites unreachable.
  • Users report Cloudflare blocking or harassing “niche” browsers, privacy‑hardened setups, RSS readers and non‑JS clients, effectively denying service to some legitimate users.

Operational convenience and feature set

  • Many use Cloudflare primarily for: free/better DNS, automatic TLS, caching, bandwidth offload, tunnels from home networks, bot/AI‑crawler filtering, and easy scaling for traffic spikes (HN/Reddit).
  • Some say Cloudflare was the difference between affording to host a media‑heavy site vs not.
  • Others point out downside: if you deeply integrate (tunnels, page rules, CDN assumptions), temporarily removing Cloudflare during outages becomes complex and may expose origin IPs.

Alternatives and mitigations

  • Suggestions include: keep registrar, DNS, and hosting separate; use multiple DNS providers and longer TTLs; mirror across hosts; use other CDNs (Bunny, CloudFront+S3), or rely on host‑level DDoS protection.
  • Philosophical split: keep things simple and decentralized even if less “hardened” vs embrace Cloudflare as cheap expert infrastructure and accept occasional correlated failures and centralization.
