Larry Tesler pioneered cut-and-paste, the one-button mouse, WYSIWYG (2005)

Reposting and Tesler’s Legacy

  • Several note this is an old article resurfacing; some see “inventor of cut/paste” as reductive.
  • Others argue that focusing on cut/paste is effective for lay audiences and conveys how early and influential his work was.
  • Some point out that he also helped coin or popularize terms like WYSIWYG, “browser,” and “user friendly,” and pushed modeless, user-centered design.

Cut/Copy/Paste: Invention vs. Adaptation

  • Multiple comments stress “cut and paste” existed as a physical publishing process long before computers.
  • Early editors (TECO, etc.) already had similar operations; Tesler is framed more as adapting and naming the concept for GUIs.
  • A key contribution highlighted is the selection model: cursor as “between characters,” selection as a range, and unified replace/insert behavior.
  • Some dislike that cut/paste introduces “hidden state” (clipboard) and prefer select-and-move or X11-style primary selection.

Modes and Interaction Philosophy

  • Tesler’s “no modes” principle is widely cited as influential; some see cut/paste as in tension with it.
  • Others note that modern tools (e.g., modal editors like Vim, car “eco/sport” modes) show modes can be powerful but must be used sparingly.

One-Button Mouse Debate

  • Strong disagreement: some call it one of the worst ideas, arguing at least two or three buttons are needed and double-click is undiscoverable and confusing.
  • Others defend it as the right choice for 1980s novices, reducing complexity vs. multi-button PARC mice with inconsistent semantics.
  • There is discussion of keyboard modifiers effectively giving the Mac “virtual” extra buttons.

WYSIWYG vs. Markup

  • Some argue WYSIWYG was revolutionary for its time, democratizing desktop publishing.
  • Others think it was a bad long-term idea: encourages ad‑hoc visual poking instead of structured document semantics, causing fragile layouts.
  • Alternatives mentioned: print preview, TeX/Markdown flows, “reveal codes,” and human-readable markup generated from visual tools.

Broader UX Themes

  • Multiple commenters lament modern regressions: inconsistent mobile UIs, loss of tooltips/manuals, touch paradigms leaking into desktop.
  • Amazon’s interface is criticized as cluttered and confusing; anecdotes suggest internal resistance to redesign, possibly for business reasons.

Other Contributions and Concepts

  • The ARM/Newton investment is noted as indirectly crucial to Apple’s survival.
  • Tesler’s Law (conservation of complexity) is referenced as a useful mental model: complexity can be shifted but not eliminated.

CSVs Are Kinda Bad. DSVs Are Kinda Good

Role and Limits of CSV

  • Many see CSV as an “ancient, lowest-common-denominator” text format that persists because it’s simple, human-inspectable, and widely supported.
  • Others stress that CSV itself is “kinda great” when used per RFC 4180; the real problem is ad‑hoc dialects and badly tested exporters/importers.
  • Several note that non-technical users equate “CSV” with “whatever Excel does,” which drives inconsistent, often broken files.

DSV / ASCII Control-Character Delimiters

  • The proposed DSV idea (using ASCII control characters like 30/31 as field/record delimiters) avoids quoting and newline edge cases.
  • Supporters like that it’s efficient to parse, solves many CSV escaping issues, and builds on long-existing ASCII concepts.
  • Critics say it sacrifices the main CSV benefit (human readability/editability in generic tools) without offering enough in return.
  • Others note practical issues: these characters do appear in some real-world “CSV” containing binary/non-plain-text data; you still need an escape strategy.

Standards, Dialects, and Pragmatism

  • One camp argues strongly for enforcing RFC 4180 and rejecting broken CSV to reduce chaos and improve interoperability.
  • Another camp counters that “broken” is a sliding scale; power asymmetries mean small suppliers must accept whatever large partners send.
  • RFC 4180 itself advises being liberal in what you accept; there’s debate over whether that helps standardization or entrenches sloppiness.

Alternatives and Tooling

  • For data you control and don’t need to edit by hand, people recommend Parquet, SQLite files, JSON/NDJSON, or other structured/binary formats.
  • TSV is popular for command-line work; seen as simpler and safer than CSV, though still fragile if tabs appear in data.
  • Some suggest augmenting CSV with a standardized metadata header (delimiter, encoding, locale, etc.).
  • Tooling quality matters: libraries like pandas, xsv, zsv, and LibreOffice Calc are praised for handling messy CSV better than Excel or naive parsers.
  • Several conclude that any format needs clear escaping rules and that “just pick another delimiter” does not by itself solve the deeper interchange problems.

Examples of Great URL Design (2023)

Slug + ID vs. Slug-only Designs

  • Many commenters like the “ID plus optional slug” pattern (e.g., /questions/:id/:slug or /dp/:id), because:
    • IDs give stable, permanent references.
    • Slugs can change with titles without breaking links.
    • Servers can ignore or 302-redirect if the slug is missing or wrong, avoiding misleading or obscene text.
  • Others find slugs unnecessary bloat: URLs get long, break when titles change, and are often unreadable in non-ASCII languages.
  • Some argue slug-only URLs are “more elegant” but require extra tables, many-to-one slug mappings, and redirects to avoid broken links or misleading slugs.

Amazon, Stack Overflow, Notion & Other Real-World Schemes

  • Amazon’s /slug/dp/id is seen as both good (human readable, SEO-friendly, ID works alone) and annoying (slug before ID makes trimming harder; URLs bloated with tracking parameters).
  • Stack Overflow’s /questions/id/slug is praised as easy to shorten and canonicalize; they 301 to the correct slug.
  • Notion, Confluence, Reddit, and news sites commonly use …/whatever-title-or-text-id, often ignoring the text and relying on the ID, with mixed feelings about prankable text and SEO motivations.
  • GitHub’s URLs are widely admired for consistency, REST-like structure, and extension-based variants (.patch, .diff, .keys).

URL Semantics, Structure, and Rules

  • Several participants endorse principles like:
    • One resource ↔ one URL; URLs should be permanent, manageable, scalable, short, and optionally contain a “speaking” slug or namespace.
    • File-like suffixes (.json, .html) can be useful for APIs; opinions diverge on exposing server-side tech extensions (.php, .aspx).
  • Debate over trailing slashes and whether they matter; consensus leans toward “not important” if behavior is consistent.

Localization, Accessibility, and UX

  • Some advocate localized slugs and language codes in paths (e.g., /en/, /cy/), arguing it respects non-English speakers and can help SEO.
  • Others say modern search and link previews reduce the importance of human-readable URLs, especially on phones.
  • Link previews themselves are divisive: some find them space-wasting and low-value; others see them as replacing the role of descriptive slugs.

Edge Cases and Technical Concerns

  • Discussions around encoding (/, +, %20) highlight complexity when allowing arbitrary characters or open-ended path segments.
  • Canonical tags and 301 redirects are frequently mentioned as necessary to avoid duplicate content and analytics confusion.

Interviewing the Interviewer: Questions to Uncover a Company's True Culture

Value and Limits of “Interviewing the Interviewer”

  • Some see questions like “what could the company improve?” as as useless as “what’s your greatest weakness”: they mostly test verbal skill and elicit diplomatic non‑answers.
  • Others argue probing questions are essential, especially for leadership roles. They show candidates care about org health and can surface whether leadership actually drives cultural improvements.
  • There is skepticism that you can get honest culture signals in a formal interview; many see it as PR, with prepared, “corporate” answers.

What to Ask and How

  • Popular “reverse interview” questions focus on:
    • Who succeeds vs struggles on the team.
    • Near‑term objectives and how this role contributes.
    • How collaboration, coordination, and on‑call work.
    • Work‑life balance, crunch periods, and deadlines.
    • Biggest challenges over the next 1–5 years.
    • What they’d change with a “magic wand” / finger snap.
    • Why the predecessor left and what would make the hire a clear success after a year.
  • Asking multiple people the same question and comparing answers, plus watching nonverbal reactions, is seen as more reliable than any single response.

Culture, Teams, and Signals

  • Debate over “engineering culture”: some say culture only really exists at team/department level; others argue there is a company‑level culture, albeit uneven and shifting.
  • Strong signals many look at:
    • Responsiveness, scheduling, and contract flexibility.
    • How you are treated logistically (breaks, respect, basic amenities).
    • Tenure of staff and how candid engineers (vs managers/HR) are.
  • Several recommend contacting former employees (e.g., via LinkedIn) for more candid views.

Salary Expectations and Power Dynamics

  • Large subthread on “what are your salary expectations?”:
    • Hiring‑side: used to avoid misalignment, work within flexible or unclear budgets, and sometimes to justify levels/bands.
    • Candidate‑side: often viewed as a tactic to lowball; many prefer the company to disclose ranges first and treat the role, not the candidate’s number, as the pricing basis.
  • Some jurisdictions require publishing salary ranges; companies may comply with very wide bands, limiting their usefulness.

Market Reality vs Ideal Fit

  • A number of posters note that in a tight market or after long unemployment, candidates may accept poor culture and keep searching later.
  • Others insist that asking hard questions and walking away from red flags is still worthwhile to avoid short, unhappy stints.

Vaultwarden: Unofficial Bitwarden compatible server written in Rust

Self‑hosting Vaultwarden: Experiences

  • Many report running Vaultwarden for years “flawlessly,” often via Docker on home servers or cheap cloud VMs.
  • Setup is considered easy for those already running reverse proxies (e.g., Caddy) and other self‑hosted services.
  • For some, Vaultwarden is invaluable for personal/family use, while they still use Bitwarden’s cloud offering at work for reliability.

Cloud vs Self‑hosted: Cost, Effort, and When It’s Worth It

  • Several concluded that for small businesses, the labor cost (setup, monitoring, patching) exceeds Bitwarden’s low per‑user cloud fees.
  • Others argue self‑hosting scales well once you’ve built up infrastructure and skills; incremental cost of another service is low.
  • Some people maintain a paid Bitwarden account anyway (to support the project, for emergency access for family, or as a fallback).

Security, Threat Models, and Updates

  • Strong warnings about relying on automatic Docker updaters like Watchtower; renames or image changes can silently stall updates or break envs.
  • Suggested alternatives: manual monitoring, Ansible, gitops workflows, or running Watchtower manually.
  • Debate over necessary “enterprise‑grade” hardening vs pragmatic home setups; many accept being safe from “random internet scans” but not state‑level actors.
  • Opinion split: some think self‑hosting a password manager is overkill risk; others see central SaaS vaults as more attractive targets.

Offline Access and Client Behavior

  • Mixed reports about offline access: some can unlock mobile apps without connectivity; others say browser extensions (especially Firefox) sometimes log out and require server contact.
  • A cited Bitwarden policy: offline sessions expire after 30 days, which pushed some to KeePass‑style solutions.

Alternatives and Comparisons

  • Alternatives discussed: KeePass/Strongbox, pass + git/syncthing, Proton Pass, 1Password, LastPass (historical).
  • KeePass/Strongbox praised for simple file‑based offline model but can be clumsy for sync/sharing.
  • Pass + git is favored by CLI‑oriented users; YubiKey integration highlighted.
  • 1Password seen by some as significantly more polished, faster, and better for non‑technical family sharing than Bitwarden/Vaultwarden.
  • Proton Pass praised for easier family sharing and email alias integration.

Migration, Backup, and Features

  • Migrating from official Bitwarden server to Vaultwarden is non‑trivial due to attachment handling; exports don’t include attachments.
  • Emphasis on robust backups (volume snapshots, offsite copies); losing a vault can be catastrophic.
  • OIDC/SSO support is under active development but currently limited to authorization, not full vault unlock.

Language Choice (Rust)

  • Discussion on using Rust vs Go: Rust favored by some for type system, safety, and personal preference, even if performance isn’t critical.

Grok-2 Beta Release

Model quality & benchmarks

  • Many see Grok‑2 as a big step up from Grok‑1 and now “near the top” with OpenAI, Anthropic, Google, Meta.
  • Thread cites LMSYS / benchmark tables: Grok‑2 appears better than most models except Claude 3.5 Sonnet, GPT‑4o, and Gemini 1.5 Pro, though different models win different tests.
  • Some are skeptical it’s more than benchmark‑tuning; others say it’s clearly “good enough to be worth using today.”
  • Several people compare it directly to Claude 3.5 Sonnet and still rank Claude ahead for coding and general quality.

API, lock‑in & business risk

  • Excitement about “one more top model via API,” with hope this drives prices down.
  • Counterpoint: many distrust X as a platform after Twitter’s API history and Musk’s erratic management; seen as risky to build a business on.
  • Others argue LLM APIs are relatively swappable (string in/out, use abstraction layers) so lock‑in is limited, though system prompts and task‑specific performance complicate migrations.

Data use, tweets & GDPR

  • Strong criticism that Twitter/X irreversibly feeds user data into Grok without clear consent, especially under EU law.
  • Explanation: once data is baked into model weights it can’t be selectively removed without retraining.
  • Debate over whether X’s ToS grants a broad enough license for AI training and how GDPR’s purpose‑limitation and consent rules apply; some insist it’s unlawful in the EU, others say data is in US datacenters and X’s lawyers seem unconcerned.

Safety, censorship & political bias

  • Users ask how “censored” Grok is compared with other LLMs; some want fewer refusals.
  • Reports: image generation blocks nudity but freely creates some shocking or political content, while seeming to over‑sanitize or distort some LGBT prompts.
  • Disagreement over whether reduced “safety” boosts benchmarks, and whether Grok is meaningfully less censored than Claude or “uncensored” open‑source models.
  • Political alignment and “alt‑right AI” fears are raised; others push back on assuming bias without testing.

EU regulation & regional availability

  • Frustration from Europeans about staggered launches and delayed features; some say they’ll just use VPNs.
  • Others defend EU privacy and consumer protections, arguing US companies must obey EU law if they operate there.
  • Debate over whether EU regulation is “dumb” in implementation (e.g., cookie popups) vs. necessary to constrain data‑mining.

Ethics, Musk, and consistency

  • Repeated criticism that xAI’s actions contradict earlier complaints about OpenAI: Grok is not open‑source, still a frontier model, and uses tweets for training.
  • Some attempt to rationalize: Grok‑1 was open‑sourced after a lag and no one else paused development, so xAI followed suit.
  • Long sub‑thread disputes Musk’s ethics, truth‑seeking claims, and “free speech” positioning, citing past behavior and moderation choices on X.

Open‑source & local models

  • A few hope for an open release of Grok‑2 similar to Grok‑1, but optimism is low.
  • Some argue the real moat is high‑quality data and massive compute, not code alone.
  • Others say they only care once a small Grok model is downloadable and quantizable for fast local use; until then they’ll stick with Meta/Mistral and other open options.

Benchmarks & evaluation limits

  • Chatbot Arena rankings are viewed with increasing skepticism: possible tuning, sample bias (English‑heavy, “vibes”‑driven), and ease of gaming.
  • Alternative niche or task‑specific benchmarks are suggested (coding, search, LiveBench), but consensus is that standardized, robust LLM evaluation remains unsolved.

Disney seeks dismissal of wrongful death lawsuit citing waiver in Disney+ terms

Scope of Disney’s Arbitration Argument

  • Disney moved to dismiss / stay a wrongful-death suit, arguing that the widower’s 2019 Disney+ free-trial ToS (with an arbitration clause) governs this dispute.
  • The clause reportedly covers “all disputes” concerning “Disney Products” and “services in any media format or channel.”
  • Many commenters find it absurd that a streaming ToS could govern a later, unrelated physical injury/death; some see it as a potential “test case” on how far ToS can reach.

Facts & Confusion About the Venue

  • The death followed an allergen reaction after dining at Raglan Road in Disney Springs, a free-entry mall on Disney property.
  • Multiple corrections: Disney Springs is not inside a ticketed park; Raglan Road is run by a separate company (Disney is landlord).
  • Disney republishes menus and allows reservations on its own site/app; debate over whether this makes it more than “just a landlord.”
  • Archived menu text shows extensive allergen disclaimers; some argue the plaintiff mischaracterized “allergen‑free” claims, others say in-person assurances by staff override boilerplate disclaimers.

Legal Debates: Contracts, Arbitration, and Strategy

  • Many argue the arbitration clause should not apply:
    • It’s tied to a different product (Disney+ vs a third‑party restaurant).
    • It targets the husband, while he sues on behalf of the deceased’s estate.
    • It’s unconscionable to waive court access for serious injury/death via a generic clickwrap.
  • Comparisons made to EU consumer rules, where such broad clauses would likely be void or limited.
  • Others note corporate defendants routinely invoke arbitration to delay and wear down plaintiffs; denial can still yield years of appeals and stays (with examples from California and federal practice).
  • A few defenders say Disney’s lawyers are “doing their job” by raising every arguable defense; critics counter this crosses into misrepresentation and abuse of process.

Broader Concerns About ToS and Corporate Power

  • Widespread condemnation of pre‑dispute forced arbitration and “fine print” that ordinary consumers cannot meaningfully read or negotiate.
  • Fears that if Disney’s theory succeeds, any prior online agreement (Google, Uber, Tesla, etc.) could be used to shield companies from unrelated tort suits.
  • Some call for boycotts/canceling Disney+, others are skeptical that consumer backlash will materially hurt Disney.

Allergies, Responsibility, and Risk

  • Separate thread on severe food allergies:
    • Some argue people with life‑threatening allergies should avoid restaurants entirely; others reject this as unreasonable and blame lax restaurant practices.
    • General agreement that kitchens are error‑prone and true “allergen‑free” service is extremely hard, but still a duty when staff explicitly assure safety.

Introducing passkey support to Fastmail

Perceived Benefits of Passkeys

  • Advocates highlight: no shared secret sent over the network, replay resistance, strong protection against database leaks and phishing.
  • Passkeys are compared to SSH keys or FIDO security keys: origin‑bound, non‑forwardable, and can’t be copied or pasted into chats or phishing forms.
  • Seen as especially beneficial for non‑technical users who don’t use password managers or reuse weak passwords.
  • Some view them as a “protocol upgrade” for password managers, simplifying security while keeping similar workflows.

Skepticism vs Password Managers

  • Several argue good password managers already provide strong, unique passwords and phishing resistance via domain‑matching and autofill.
  • Critics say the only significant incremental benefit is replay resistance, and that advantages are being oversold.
  • Concerns that people bypass autofill and copy‑paste into phishing sites, undermining theoretical protections.

Usability, UX, and Edge Cases

  • Confusion reported among less‑technical users when prompted to “migrate to passkeys.”
  • Edge cases raised: logging in on shared/hotel/work computers, device loss while traveling, broken phones, and reliance on backup hardware or recovery schemes.
  • Some frame “you can’t log in from an untrusted machine” as a feature; others see it as dangerously inflexible for critical access.

Vendor Lock‑in and Sociological Concerns

  • Strong worry that passkeys deepen dependence on big tech ecosystems and cloud keychains (Apple, Google, etc.).
  • Fear that once passwords are phased out, users will effectively be forced into particular vendors.
  • Counter‑argument: passkeys can also live in third‑party or self‑hosted password managers and hardware keys, potentially reducing dependence on phones and SIM‑based OTP.

Implementation Details and Ecosystem Support

  • Questions about Chrome/Windows cloud sync; one reply suggests storage in TPM but details remain unclear.
  • CTAP2/WebAuthn flows (QR codes, phone as security key) are cited as a way to use passkeys on other devices without revealing credentials.
  • Some complain that discoverable passkeys make older hardware keys with small slot limits less useful.

Fastmail-Specific Feedback

  • Login UI with initial “username only” field is divisive: some dislike extra steps; Fastmail staff justify it for passkey/SSO flows and non‑resident keys.
  • Billing complaints about inability to prepay long in advance; Fastmail explains constraints of new billing provider and describes grace periods.
  • Security critique around DMARC and STARTTLS; Fastmail management disputes the characterization and outlines current practices and rationale.

The TikTok Case Will Be Determined by What's Behind the Government's Black Lines

CCP control, data access, and national security

  • Many argue TikTok is inseparable from the Chinese state due to Chinese national security law, government board seats, and the obligation of Chinese firms to assist security services.
  • Others demand concrete proof of direct CCP orders or data handovers, and point to arrangements like Oracle hosting US data as possible mitigations.
  • Some say the core risk isn’t just spying but long‑term blackmail (especially of today’s youth) and psychographic profiling via massive behavioral data.

Propaganda, algorithmic influence, and “information warfare”

  • One side sees TikTok as an “incredibly effective mass propaganda machine” whose recommendation algorithm could be tuned to favor CCP narratives, shape public opinion, and destabilize democracies.
  • Examples raised: geofenced content around Russia/Ukraine, different content streams to Russian vs Ukrainian youth, and contrasting treatment of TikTok’s Chinese vs US versions.
  • Skeptics argue intelligence agencies overestimate “mind control” power; attention is already intensely contested by advertisers and domestic platforms, and foreign propaganda usually needs local influencers, not just algorithms.

Domestic surveillance vs foreign adversary

  • Several commenters highlight US/EU surveillance capitalism and weak privacy laws, seeing the TikTok focus as hypocritical protectionism for US tech.
  • Others respond that domestic corporations, however abusive, are not arms of a hostile state preparing for potential war; direct platform control by China is seen as a qualitatively different threat from buying ad/targeting data.

Reciprocity, market access, and geopolitics

  • Strong support for a reciprocity argument: if China bans US social media and news on “national security” grounds, the US need not allow Chinese platforms unrestricted access.
  • Others warn that copying China’s restrictive approach undermines the West’s free‑speech advantage and could normalize censorship globally.
  • Some frame this in a broader “Second Cold War” and possible Taiwan conflict, arguing that reducing Chinese influence over Western information space is part of war‑preparation.

Free speech, censorship, and moderation

  • Free‑speech absolutists oppose bans and extensive content policing, arguing that exposure to offensive content is a life lesson and that regulating speech (state or corporate) is more dangerous.
  • Others stress the harm from algorithmically amplified hate (e.g., antisemitic harassment) and want stricter moderation, while disagreeing over what counts as antisemitism vs political criticism.
  • Several see banning TikTok as “right thing for the wrong reason,” preferring broad privacy and interoperability laws that would constrain all large platforms, foreign and domestic.

John Rawls, liberalism and what it means to live a good life

Rawls’ Original Position & Veil of Ignorance

  • Some see the veil of ignorance as basic moral “table stakes”: design rules you’d accept without knowing your identity.
  • Others argue it’s actually radical if applied consistently (e.g., to criminals, persecuted minorities).
  • Critiques:
    • It ignores knowledge gained from being disadvantaged.
    • It can incentivize ignoring tiny groups (low probability of being them).
    • It presupposes that “fair, identity-blind” rules are the right starting point.
  • Defenders say it’s not a literal optimization problem but a way to insist rules be acceptable from any social position.

Probability, Risk, and Maximin

  • Rawls is said to favor “maximin”: maximize the worst-off outcome, even if it lowers average welfare (e.g., choosing “Junkland” over “Omelas”).
  • Economically minded commenters object that this ignores probabilities and rational risk-taking.
  • Counterexamples (Omelas, potato farmers, green/blue segregation) are used to probe tradeoffs between fairness, total welfare, and feasibility.
  • Some argue the setup pushes people to overweight unlikely worst cases and prioritize small minorities.

Kant vs Rawls

  • Kant’s categorical imperative (universalizable maxims) is contrasted with Rawls:
    • Kant focuses on logical consistency of rules, not imagining you might be anyone.
    • Rawls explicitly asks you to choose rules you’d accept from any social role.
  • Problems with Kant noted: level of rule detail, edge cases, rigid bans on lying.
  • One point: Kantian universalization could in principle justify oppressive norms if you’re happy with them; Rawls’ veil can’t because you might be the oppressed.

Liberalism, Capitalism, and Fairness

  • One line of argument praises liberal constitutional orders: rule of law, contract enforcement, freedoms, everyday trust are framed as a “miraculous” achievement.
  • Critics respond:
    • Rising costs (housing, healthcare), exploitation (fast food, tobacco, HFCS subsidies) and lobbying show the system often prioritizes profit over people.
    • Large inequality is not obviously necessary; more equal systems (e.g., Nordics, mentioned as comparison) might trade some growth for fairness.
  • Defenders of markets claim:
    • Modern capitalism created huge value versus historical alternatives.
    • Inequality is an acceptable byproduct of voluntary choices and risk-taking.
  • Others invoke Rawls: would the worst-off prefer a slightly poorer but more equal system?

Sources of Values and Secular Morality

  • Some secular participants reject the idea that one needs a religion-like, civilization-scale source; they cite:
    • Empathy plus logical consistency.
    • Personal intuition and cooperative instincts (moral relativism).
    • Systems theory and needs of complex adaptive systems.
  • Others argue many Western secular values (empathy, human rights) are culturally shaped by Christianity, even for non-believers.

Empathy, Culture, and Moral Scope

  • Empathy is argued to be culturally constructed: who deserves empathy, and for what, varies.
  • Examples:
    • Homelessness policy (tolerating street sleeping vs removing people to shelters).
    • Market-oriented views that bracket empathy in favor of profit.
  • Individualism is seen by some as reducing the practice or scope of empathy, even if capacity remains.

Strongmen, Discontent, and System Legitimacy

  • One view: people backing strongmen are entitled/myopic and forget how much better life is than in the past.
  • Others counter:
    • Large electorates choosing strongmen signal deep dissatisfaction with current institutions.
    • Voters care about present lived reality, not historical baselines.
  • Debate over whether such voters “want to give up rights” vs are seeking to escape a bad position in the social hierarchy.
  • This is linked back to Rawls: if many are ready to abandon liberal democracy, perhaps it no longer passes an “original position” legitimacy test.

Socialism, Anarchism, and Liberal Variants

  • Discussion on how liberalism intersects with:
    • Liberal socialism (strong state, redistribution).
    • Liberal anarchism / voluntarism (stateless cooperation).
  • Disagreement over definitions:
    • Some treat socialism as inherently state-centered; others note long traditions of stateless socialism/anarchism.
    • Anarcho-capitalism is contested as “anarchist” because it preserves capitalist hierarchies that traditional anarchism rejects.

Ask HN: What do you monitor on your servers?

What people actually monitor

  • Beyond CPU/RAM/disk, many emphasize:
    • Disk I/O, latency, IOPS, and filesystem inodes.
    • Network throughput, connection counts/states, retransmits, error rates.
    • Swap and memory pressure (page faults, PSI, OOM events), less focus on “RAM used”.
    • Service and unit health: systemd failures, restarts, timers, cron jobs.
    • HTTP metrics: uptime, error rates (4xx/5xx), latency percentiles, throughput.
    • DB metrics: query rates, slow queries, cache/index usage.
    • Security/health: RAID, SMART, TLS/domain expiry, failed logins, firewall events.
    • “Pressure/saturation” metrics and thread/task pool utilization as better indicators than raw CPU/RAM.

Application vs server monitoring

  • One camp: server metrics alone are low-value noise once sizing is done; the real value is app metrics, APM, and tracing.
  • Another: you must also monitor hardware/OS (logs, MCEs, disk errors, network) or you’ll misdiagnose weird failures.
  • Widely agreed: monitor both, but app-level SLOs (uptime, latency, error rate) are the primary “is it working?” signals.

Tools and ecosystems

  • Very common stacks:
    • Prometheus + Grafana (+ node_exporter, process_exporter, Alertmanager; Mimir/Thanos for scale; Loki for logs).
    • Netdata for “instant everything” on single hosts.
    • Nagios/Icinga/Checkmk/Monit/Zabbix for classic active checks.
    • Commercial APM/monitoring: Datadog, New Relic, Azure App Insights.
    • Homelab/simple: Uptime Kuma, HetrixTools, PRTG, basic scripts + Grafana.
  • VictoriaMetrics gets both praise (performance, simplicity, cheaper storage) and criticism (API/PromQL differences, perceived FUD marketing).

Logs, tracing, and collectors

  • Logs: Loki+promtail, Vector, Fluentd, journald collectors, syslog-based setups; some want “poor man’s” central log solutions.
  • Tracing seen as highly valuable; some feel most other telemetry is “noise”.
  • Several recommend single, lightweight host agents (e.g., vmagent, Coroot’s eBPF agent, Telegraf/collectd).

Push vs pull and OTEL

  • Push advocates: easier to scale, central pullers have timing and load issues.
  • Pull advocates: Prometheus-style scraping plus service discovery makes it clear who’s missing.
  • OpenTelemetry:
    • Proponents: industry standard, avoid reinventing protocols, build custom distros.
    • Critics: overengineered, opaque errors, immature in some languages; prefer Prometheus/StatsD-style simplicity.

Meta and philosophy

  • Strong advice not to “reinvent the wheel” unless there’s a clear, differentiated vision.
  • Emphasis on actionable metrics and anomaly detection, not “pretty graphs”.
  • Some only monitor cost-relevant or business-impacting metrics; others try to “monitor everything” to ease debugging.

US Air Force avoids PFAS water cleanup, citing Supreme Court's Chevron ruling

Impact of overturning Chevron on PFAS and regulation

  • Many argue the Loper Bright decision (ending Chevron deference) will make PFAS cleanup and future regulation much harder, because every significant rule can now be litigated and delayed for years.
  • Others claim this is overstated: courts can still uphold regulations, and Congress can pass clear laws granting broad authority over pollutants.

Courts vs agencies vs Congress

  • One side says expertise should stay with agencies like the EPA; judges lack scientific knowledge and turning technical disputes into legal ones is dangerous and politicizing.
  • The other side argues agencies had been effectively “making law” beyond what Congress authorized, and courts simply resume their traditional role of interpreting ambiguous statutes.
  • Some emphasize that laws can grant broad, unambiguous regulatory authority without naming each chemical; critics respond that such drafting is impractical.

Congressional dysfunction and democratic legitimacy

  • A recurring theme: Congress is too polarized and gridlocked to update statutes at the speed required for modern regulation.
  • Supporters of the ruling respond that using agencies to bypass a nonfunctional legislature is an undemocratic “hack” that undermines separation of powers.
  • Opponents counter that in practice, the choice is between expert-led regulation and no meaningful regulation at all.

Judicial partisanship, expertise, and corruption concerns

  • Multiple comments argue federal courts, especially the Supreme Court, are highly partisan, ideologically driven, and less accountable than agency staff.
  • Others insist judges are trained in ethics and impartiality, can consult experts, and remain accountable via impeachment, unlike entrenched bureaucrats.

Air Force vs EPA and executive-branch conflict

  • Commenters note the oddity of one executive agency (Air Force) resisting another’s (EPA) determinations, given presidential control over both.
  • Some suggest this reflects internal politics or deliberate pre-election positioning; others stress that large bureaucracies routinely conflict and aren’t truly “monolithic.”

Comparisons and broader consequences

  • Analogies are drawn to firearms regulation (ATF), Flint’s water crisis, and border and climate policy to illustrate either regulatory overreach or the cost of weak regulation.
  • A Swedish PFAS case is cited where courts held local government ultimately responsible for providing clean water, regardless of military pollution.
  • Several foresee increased pollution, litigation, and need for private filtration and personal risk mitigation.

Ozempic is changing people's skin, say plastic surgeons

What Ozempic Is and How It’s Used

  • Some commenters note that Ozempic (semaglutide, a GLP‑1 agonist) is primarily a diabetes drug but widely used off‑label for weight loss.
  • Others outside the US/UK say they’d barely heard of it or that it’s restricted to type 2 diabetics.
  • A claim appears that millions of Americans use it, roughly half without diabetes.

Skin Changes and “Ozempic Face”

  • Several note that rapid weight loss often makes people look older: looser skin, sharper features.
  • The article’s suggestion that Ozempic causes distinct skin changes is viewed as important if true, but currently unclear.
  • Some speculate that poor diet quality plus eating less (same junk food, smaller amounts) may cause malnutrition that worsens skin and tissue quality.
  • A few propose pairing GLP‑1 drugs with skin‑care interventions (retinoids, vitamin A, collagen), while others warn about side‑effects and “pill for the pill” cascades.

Is It the Drug or Rapid Weight Loss?

  • One key quote highlighted: a surgeon claims he does not see the same facial changes in diet or surgery patients, suggesting a GLP‑1‑specific effect.
  • Others point out the article also links similar patterns to other rapid weight loss, calling the messaging internally inconsistent and possibly FUD.
  • Overall: mechanism is unresolved; correlation vs causation is explicitly questioned.

Muscle Loss, Diet Quality, and Exercise

  • Concerns that up to ~50% of lost weight on GLP‑1s can be lean mass; commenters advocate high protein intake and resistance training.
  • Others argue exercise modestly affects weight but strongly affects composition and metabolic health.
  • There is disagreement on how much exercise “matters” for fat loss vs diet and drugs.

Risk–Benefit Framing and Moral Attitudes

  • Some emphasize that obesity’s risks (diabetes complications, cardiovascular disease) dwarf cosmetic downsides like sagging skin.
  • Others see cultural hostility to “easy” pharmacologic weight loss, with moral overtones about willpower and “cheating.”
  • Skeptics invoke past disasters (e.g., earlier weight‑loss drugs, rodent thyroid tumors) and unknown long‑term effects.

Conflicts of Interest and Media/Industry Incentives

  • Multiple comments question plastic surgeons’ incentives: they profit from both liposuction and post‑Ozempic skin procedures.
  • The article is criticized as click‑driven, vague on mechanism, and possibly amplifying fears.

The Blue Collar Jobs of Philip Glass

Replicating Glass’s Path Today

  • Many doubt a young artist could now support a family in a major cultural center on 3–4 days of blue‑collar work; wages vs. housing costs and part‑time availability are seen as worse.
  • Others argue similar “make your own opportunity” paths still exist, but with different tools (internet distribution, remote work, FIRE/ERE approaches).
  • Some stress that scenes like 1970s New York (cheap, dense, artistically central) are historically rare; today’s equivalent might be fringe neighborhoods, smaller cities, or college towns.

Cost of Living, Labor Markets, and Blue-Collar Work

  • Commenters describe stricter licensing, background checks, and ladders “pulled up” compared to eras when people could bluff into skilled work and learn on the job.
  • There is disagreement: some say low-skill jobs are still easy to get if you reliably show up; others say employers are too picky post‑2008 without connections.
  • Gig work (Uber/Lyft) is seen by some as equivalent to old taxi jobs, but others argue that real purchasing power has fallen sharply.

Place, Scenes, and Creativity

  • One camp says rural cheap living enables art if you accept material sacrifice; another calls it creatively deadening without rich stimuli and peer networks.
  • Counterexamples are offered: important artists working outside big cities, or composers who labored in obscurity and were later recognized.
  • Several note that some arts (orchestral music, theater) still require in‑person collaboration and audiences, even in the age of YouTube.

Academia and the Art World

  • Tenure-track arts jobs are described as extremely scarce, with aging faculty blocking new hires.
  • Many artists teach in precarious, non‑tenure roles; academia and “serious” art are portrayed as often conservative and detached from innovators.
  • Others note that social media has opened new non‑academic routes to audiences for niche intellectual or artistic work.

Class, Privilege, and Inequality

  • Debate over whether inherited wealth vs. innate talent should be treated similarly as “unearned advantages.”
  • Some argue the modern art world leans more on family money or supporting spouses due to wealth concentration and a squeezed middle class.
  • One commenter frames generative AI as a moral redistribution of creative talent; another criticizes “just world” assumptions that good work will always be discovered.

Value and Perception of Blue-Collar Work

  • Multiple stories highlight blue‑collar workers reading serious literature, being intellectually curious, or effectively “invisible” to others.
  • Manual labor is often described as physically tiring but mentally freeing, sometimes better paired with heavy reading than white‑collar cognitive work.
  • Some see the article (and others like it) as romanticizing or patronizing blue‑collar life when undertaken by famous artists, while ignoring “ordinary” workers.

Artistic Careers, Anonymity, and Motivation

  • Commenters emphasize that most artists never make a living from their art and rely on day jobs; this is framed as normal rather than exceptional.
  • Survivorship bias is raised: many live Glass‑like lives of struggle without recognition.
  • Others stress that genuine artists create regardless of success; anonymity doesn’t negate the value of their work.

Reactions to Glass Himself

  • Several anecdotes underline his humility and accessibility (e.g., free public concerts, casual interactions).
  • His openness about composing “for money” is praised as honest, and his role in transforming late‑20th‑century classical music is highlighted.
  • Some readers say the story inspires respect and re‑evaluation of his music; others remain musically indifferent but admire his work ethic and attitude.

Pixel Watch 3

Battery life expectations

  • “All‑day” battery is widely seen as inadequate. Many compare to Garmin and other fitness watches with 1–4 weeks, or at least several days of life.
  • Several users say if you must charge daily, you might as well optimize for a week or more; once‑a‑month charging is viewed as a major convenience boost.
  • Others argue daily charging becomes routine (e.g., during shower or before bed) and they never run out, so longer battery is less important unless it stretches to many days.

Smartwatch vs fitness watch

  • Strong theme: Pixel Watch (and Apple/Samsung) are “mini phones” with short battery and app ecosystems, while Garmin/Coros/Suunto are focused “tools” for fitness with rich built‑in training features and long‑term stats.
  • For serious runners/triathletes, Garmin‑style devices are described as clearly superior in training metrics and battery, with only basic “smart” features needed (notifications, payments, find‑my‑phone).
  • Fitbit/Pixel fitness stack is often criticized as “toy‑like”: limited data access, vague graphs, and unreliable sensors compared to Garmin.

Notification & UX critiques

  • Multiple Pixel Watch owners complain strongly about notification UX: vibrations without immediate content, gesture delays, intrusive animations, and disappearing notifications.
  • Older Pebble (and early Wear OS) behavior is held up as better: instantly showing full notifications with simple UX.
  • Some see Android Wear / Pixel Watch as laggy, low‑information, and under‑iterated, despite decent hardware.

Form factor & design

  • Debate over round vs rectangular: round is praised aesthetically and for “watch‑like” feel; rectangular is favored for better information density and scrolling content.
  • Some find the Pixel Watch aesthetically unappealing or “toy‑like” compared to Apple or traditional watches; others like its small size, noting the 3’s growth in size is a negative.

Google’s product culture & support

  • Several anecdotes suggest poor internal dogfooding at Google (senior people using Apple gear), leading to lack of empathy for real‑world issues.
  • There is frustration over unresolved or downplayed problems (e.g., Pixel Watch 2 GPS dropouts, ecosystem/Workspace calendar sync issues), and a sense that Google often ships hardware then under‑supports it.

Ecosystem lock‑in & alternatives

  • Apple Watch is praised for deeper integration (Mac unlock, payments, apps, cellular calling) but criticized for daily charging and being iPhone‑only.
  • Many recommend Garmin or hybrid watches (Withings, etc.) for users who prioritize battery life, simple notifications, and health metrics over “full” smartwatch capabilities.

All of Earth's water in a single sphere (2019)

Visualization, Scale, and Intuition

  • Many find the spheres visually striking but hard to intuit; the 860‑mile water sphere looks “small” next to Earth despite reaching far into space.
  • Several note that oceans are just a very thin film on a large rock: average ocean depth (~few km) vs Earth’s ~12,700 km diameter.
  • Some argue the graphic is inherently misleading because it compares volume to planetary volume; others say it effectively conveys the thinness and preciousness of Earth’s water.
  • Suggestions include overlaying “equivalent depth” over the U.S., using cubes instead of spheres, or comparing to “accessible crust” volume rather than the whole planet.

Freshwater vs Total Water

  • The smallest sphere (lakes and rivers) and the medium sphere (all liquid freshwater including groundwater and swamps) are highlighted as surprisingly small.
  • Back‑of‑envelope calculations show large per‑person allocations if all freshwater were evenly divided, but commenters stress distribution, accessibility, and pollution matter more.

Water in the Mantle and Definitions of “Water”

  • Multiple comments note newer research suggesting the mantle may contain as much H₂O (bound in minerals) as all oceans combined.
  • The USGS numbers are based on a 1993 source and exclude this mantle water.
  • Debate over whether mantle H₂O should “count” as water: some say it’s hydroxyl in minerals, effectively inaccessible; others still see it as part of Earth’s total water inventory.

Physics, Shapes, and Math Pedantry

  • Discussion on whether a Ceres‑sized water sphere would stay intact in space: gravity would form a sphere, but stability depends on temperature (freezing vs boiling/sublimation).
  • Repeated riffs on how humans misjudge curved volumes; spheres and small radius changes drastically affect volume.
  • Lengthy side thread on “polynomial vs exponential” growth and the colloquial misuse of “exponential.”

Comparisons and Thought Experiments

  • Comparisons to Ceres, icy moons (Europa, Ganymede), and Jupiter’s liquid hydrogen “ocean.”
  • Speculation about crashing Ceres or Europa into Mars to terraform it, with pushback on catastrophic side effects and timescales.
  • Related analogies: all mined gold as a ~22 m cube, all humans as a ~1 km “meat sphere,” atmosphere as a sphere comparable in size to the freshwater one.

Why did Borland ignore the Macintosh market?

Borland and the Macintosh Market

  • Several commenters note Borland did ship Mac products (e.g., Turbo Pascal for Mac in the mid‑80s) but exited relatively early.
  • Consensus: Borland prioritized DOS/Windows because that’s where the developer volume and corporate money were; the Mac market was “tiny” by comparison.
  • One view: as a relatively small company, Borland lacked resources to maintain full parallel toolchains for a niche platform, so only Pascal made it over.

Mac Market Size and Where Macs Were Used

  • Strong agreement that, through the 80s–90s, Macs were niche versus IBM‑compatibles:
    • In the US: common in education, desktop publishing, graphic design, multimedia, some CAD and science/medicine, but rare in general business and home use.
    • Outside the US (especially Europe/Eastern Europe): described as “nonexistent” or “zombie platform” outside creative and high‑end publishing houses.
  • Multiple timelines from schools: Apple II dominance → mixed Apple II/Mac/PC → PC labs only, with a small Mac presence for specialized use.

Developer Tools and Ecosystem

  • Many posts praise Borland’s tools (Turbo Pascal, Delphi, C++ Builder) as highly productive, especially for GUI/RAD and component-based development.
  • Early Borland was seen as hobbyist‑friendly and revolutionary on price ($49–99), undercutting “business‑class” compilers; later Borland moved up‑market and became expensive.
  • On the Mac side, THINK C/THINK Pascal and later CodeWarrior are widely remembered as the de facto standard, often preferred over Apple’s own MPW tools.
  • Mac OS and early apps had strong Pascal roots, but serious Mac software typically mixed Pascal or C with substantial assembly.

Why Borland Focused Elsewhere

  • Main reasons cited:
    • Much larger PC/Windows corporate developer base and upgrade revenue.
    • Mac’s limited, geographically uneven market and high hardware prices reducing volume.
    • Porting complexity: very different GUI APIs, reliance on assembly, and small payoff.
    • Internal issues: mergers (e.g., Ashton‑Tate), management missteps, and strategic drift into “enterprise” tooling reduced capacity to chase smaller platforms.

Apple’s Later Turnaround (Contextual)

  • Several commenters stress that Apple’s current strength is not indicative of its 80s–90s position; it nearly failed and was revived via NeXT/OS X, iMac, then iPod/iPhone.
  • This retrospective makes Borland’s lack of deep Mac investment appear rational given the information and economics at the time.

Google Pixel 9 Pro

Update Policy, Regulation, and Longevity

  • Multiple comments confirm 7 years of OS and security updates for Pixel 9 series (and 8 series), aligning with upcoming EU rules requiring ~5+ years of updates after end-of-sale.
  • Some see this as genuine progress; others note Apple/Google largely did it because EU regulation forces their hand.
  • Several people keep older Pixels (4a, 5, 6a) and extend life via LineageOS, GrapheneOS, or other ROMs; concern remains about security once official support ends.

AI, Gemini, and “AI Phone” Positioning

  • Many are turned off by heavy “AI” marketing and don’t want an “AI phone,” seeing it as hype and investor-pleasing rather than user-driven.
  • Gemini Advanced is widely criticized as confusing, weak, and overly restrictive compared to other LLMs; some say they only use it because it’s bundled with Google One.
  • Others report Gemini and on-device features (call screening, “Hold for Me,” photo tools, audio cleanup) as genuinely useful.
  • Confusion about which AI runs on-device vs cloud; some praise huge context windows, others report failures or refusals on real tasks.

Hardware, Cameras, and Design

  • Mixed reaction to the new design: many dislike the revised camera bulge and rounded-square (“Bender-like”) look; others shrug that all phones now look similar.
  • Some praise the “Pro specs in smaller size” move and the existence of a Pro XL, but there’s strong ongoing demand for truly small phones with good hardware.
  • Many lament loss of rear fingerprint sensors and headphone jacks; under-display readers and glass backs are often criticized.
  • Debate over camera progress: telephoto and large sensors are valued, but some feel camera bumps and 42MP front cameras are overkill.

Performance, Tensor, and Reliability

  • Tensor chips are viewed as behind Snapdragon/Apple in raw performance and efficiency; some report overheating, poor battery, or modem issues on prior Pixels.
  • Others say recent Pixels (esp. 8/8a) are very stable and “just work”; conflict between positive and negative anecdotes is noted.
  • Several see Pixels as poorly QA’d “beta devices,” citing bugs after updates (Bluetooth, calls, 911 issues historically), while others report flawless long-term use.

Privacy, Ecosystem, and Alternatives

  • Pixels are simultaneously seen as “most privacy-invasive Android” (Google) and “best base for privacy” (GrapheneOS, CalyxOS).
  • Some refuse any Google hardware due to product shutdowns and subscription dark patterns; others buy Pixels because they’re the only devices supported by GrapheneOS.
  • Desire for Linux phones (PinePhone, Librem 5) or simpler, non-AI-focused devices surfaces, but most acknowledge app/ecosystem lock-in.

Pricing and Value

  • Many experience sticker shock at ~$1,000+ pricing and see the Pixel 8a or older flagships as far better value.
  • Trade‑in and carrier deals can make upgrades cheap or nearly free, but critics note this is often offset by expensive postpaid plans.
  • General sentiment: smartphones have plateaued; for many, there’s little reason to upgrade if an older phone still works and gets security updates.

DUNE scientists observe first neutrinos with prototype detector at Fermilab

Role and properties of neutrinos

  • Non‑physicists ask what neutrinos “do” and whether they’re more than a beta‑decay byproduct.
  • Replies stress they’re elementary leptons (like electrons/muons but neutral), not force carriers.
  • They help conserve quantities (lepton number, spin) in weak interactions such as beta decay.
  • They interact only via the weak force (and gravity), making them extremely hard to detect but useful for probing otherwise opaque regions (Earth, dust clouds, supernovae).
  • Some oversimplified analogies (“chargeless electrons”, “side effect of decay”) appear; others emphasize they’re fundamental fields storing energy like all particles.

DUNE experiment and beam-through-Earth setup

  • The neutrino beam runs from Fermilab to a near detector on site, then ~800 miles through Earth to far detectors deep underground in South Dakota.
  • Near detector is expected to see ~50 interactions per beam pulse at 1 Hz; far detectors see far fewer.
  • A former student describes the beamline: protons → target → secondary charged particles → decay pipe → neutrinos; near/far detectors compare flavor oscillations to probe neutrino properties and matter/antimatter asymmetry.
  • Commenters note similar past long‑baseline experiments (e.g., CERN–Gran Sasso, K2K, NOvA).

Neutrino communication and latency speculation

  • People are fascinated by sending a controllable neutrino beam through Earth and imagine “tweet‑by‑neutrino” or replacing routing with direct through‑planet links.
  • A cited 2012 demo achieved ~0.1 bits/s over ~1 km including 240 m of rock.
  • Latency advantage of a chord through Earth vs around the surface is estimated at ~24 ms in a maximal case; huge for high‑frequency trading, but bit‑rate and detector integration time make it impractical.
  • Discussion of jamming: blocking is impossible, but flooding a region with neutrino “noise” might jam if the receiver location is known. Some detectors can infer direction to help filter signals.

Connections to gravitational waves and multi-messenger astronomy

  • Several comments highlight the “multi‑messenger” goal: simultaneous detection of gravitational waves, light, and neutrinos from events like mergers or supernovae.
  • Far‑future idea: using a long neutrino baseline through Earth as a gravity‑wave detector.
  • Skepticism: no neutrino mirrors, unclear feasibility of neutrino interference experiments, and lack of precise speed measurements limit this approach. Resolution requirements seem far beyond current detectors.

Interaction probability, straight‑line travel, and tomography

  • Non‑experts are puzzled that the beam isn’t deflected by the crust. Responses: interaction probability over ~750–800 miles is about 1 in 10^15 for typical solar‑like energies.
  • Analogies: to a neutrino, solid lead is mostly empty; blocking half the neutrinos would require fantastically large thicknesses of lead or extreme densities (e.g., neutron‑star matter).
  • This explains why long‑baseline beams work but also why using neutrinos for “CAT scanning” Earth is hard: you need huge detectors and intense sources. Current detectors are tens of meters and tens of thousands of tons of liquid argon, buried deep underground to avoid background.

Applications, funding, and everyday impact

  • One commenter questions whether such experiments should be a spending priority given limited obvious practical benefits.
  • Others answer that neutrino comms or other uses might become important, analogous to how radio waves evolved from curiosity to infrastructure.
  • They argue that understanding fundamental physics (mass hierarchy, oscillations, matter/antimatter asymmetry) has broad downstream value even if immediate consumer applications are unclear.
  • Speculative near‑term uses mentioned: submarine communication and nuclear non‑proliferation (reactor monitoring), though some call these unrealistic with current detector capabilities.

Fermi paradox and technosignatures

  • A side discussion argues that focusing on radio silence to infer we’re alone is misguided: our own radio leakage window was short, power has dropped, and encryption makes signals noise‑like.
  • Others clarify that the Fermi paradox is mainly about the absence of any evidence (including visitation or large‑scale engineering), not just radio.
  • There’s debate over whether the paradox is meaningful:
    • One side emphasizes huge galactic timescales, modest speeds (∼1–10% of light) still allowing broad colonization over billions of years, and the plausibility of many technosignatures (Dyson‑like structures, etc.).
    • The other side stresses severe uncertainties: unknown probabilities for life, unknown feasibility/economics of interstellar travel, unknown signatures and limited search capabilities.
  • Consensus in the thread is not reached; both “we’re not looking right/long enough” and “this really is puzzling” views are represented.

Humor and naming

  • Many jokes play on the DUNE acronym vs the Dune novels (Arrakis, “the spice must flow”), and on neutrinos as future communication tech or alien packet radio.
  • There are also lighthearted complaints about confusing acronyms (e.g., ROOT) when searching the web.

You've got to hide your myopia away: John Lennon's contact lenses

Lennon’s Vision and Iconic Glasses

  • Discussion notes how late in his career Lennon adopted the now-iconic round “Lennon glasses,” and that their small, round shape is ideal for strong prescriptions.
  • Some speculate stage sunglasses were likely prescription due to his level of myopia.
  • Several mention the trauma-focused cover of a Yoko Ono album featuring his bloodied glasses, which some readers found grotesque or had never noticed before.

High Myopia, Astigmatism, and Contact Lens Types

  • Multiple users with very high myopia report excellent results with modern soft lenses versus thick, optically compromised glasses.
  • Others with astigmatism describe better clarity from rigid gas permeable (RGP) or hybrid lenses than from soft lenses, though RGPs can be initially uncomfortable and risky for sports.
  • Toric soft lenses for astigmatism are discussed in depth:
    • Some say lenses have orientation marks and weighted geometry; they self-align but may take time.
    • Others report rotation problems, limited axis options, or poor comfort, leading them back to glasses.
    • Several note that mild astigmatism is often left uncorrected in contacts.

Refractive Surgery: LASIK, PRK, ICL, RLE

  • Many describe LASIK or PRK as life-changing, with freedom from glasses/contacts and only mild, manageable side effects (dry eyes, halos).
  • Others report serious or long-lasting issues: poor vision post-op, long recovery, night artifacts, or eventual regression, leading them to avoid surgery.
  • There is debate over complication and long-term failure rates; one commenter cites low success rates, another calls that selection bias and asks for peer-reviewed data.
  • Implantable collamer lenses (ICL) are highlighted as reversible and, according to some, safer or with fewer side effects; others say searches suggest higher infection risk than LASIK. Long-term data is described as limited and risk tradeoffs as non-trivial.

Glasses vs. Contacts: Comfort, Cost, and Lifestyle

  • Strong divide: some find glasses comfortable and simple; others complain about fogging, smudging, narrow field of view, and problems with sports, outdoor work, and sex.
  • Contacts are praised for full field of view and activity freedom, but criticized for rotation issues, risk of grit, and infection.
  • High prices of glasses are attributed to a global frame/lens cartel; several recommend low-cost online vendors.

Presbyopia and Multifocal Solutions

  • Aging users note needing to remove glasses to read or add readers over distance correction.
  • Multifocal and monovision contacts, plus new presbyopia eye drops, are mentioned as options, with mixed success reports.
