0. Firefox for iOS now has a native adblocker (support.mozilla.org)

609 points · 251 comments · by pentagrama

Mozilla’s support page could not load because of a client challenge, so the article’s details about Firefox for iOS’s native ad blocker could not be verified. [src]

The discussion welcomed Firefox’s iOS ad blocker but noted that uBlock Origin Lite inherits Manifest V3 limits, making it less capable than desktop Firefox’s full uBlock Origin; AdGuard and Wipr may block more broadly across iOS web views [3][4][5]. Several commenters blamed Apple’s WebKit restrictions for Firefox’s limited extension support, while criticizing Apple for allowing alternative browser engines only in the EU and Japan; Orion was seen as a workaround but potentially unreliable [1][2]. Others debated ad blocking’s broader impact, arguing that abusive, resource-heavy ads should be targeted rather than all advertising, since ads fund content creators, while critics pointed out that Firefox still permits some ads tied to its own revenue [7][8][9].

1. Claude: System Prompts (platform.claude.com)

609 points · 246 comments · by tosh

Anthropic’s Claude Platform Docs catalog periodic system-prompt updates for Claude’s web and mobile apps, noting that these changes provide current information and guide behavior but do not apply to the Claude API. [src]

The main discussion centers on reconstructed Claude system prompts: commenters find the version history useful, but criticize Anthropic for omitting tool definitions and Claude Code prompts [1]. Several question whether lengthy, sometimes contradictory instructions waste context or even degrade performance, while others note that providers likely retain hidden safeguards regardless of user prompts [2][6][7]. The thread also includes a side debate over alleged anti-AI moderation bias on Hacker News; one side suspects downranking or flagging, while others attribute the examples to community flags, flame-war filters, and weak or inflammatory article quality rather than conspiracy [0][4].

2. A third world engineer responds to “RISC-V: They should have known better” (rvembedded.com)

439 points · 232 comments · by Narishma

An embedded engineer from Trinidad and Tobago counters criticism of RISC-V, arguing that its low cost, openness, and scalability make computing accessible worldwide despite legitimate concerns about fragmentation and architectural quirks. [src]

The discussion largely agrees that RISC-V is compelling for inexpensive, highly customized embedded hardware, but commenters dispute whether it can compete with ARM in performant general-purpose systems due to fragmentation, optional extensions, and weaker current implementations [1][5][6]. Several people challenged the article’s shipping-cost argument: logistics costs are independent of ISA and may overwhelm the small per-chip savings, while some noted that Nigeria and Bangladesh are already well connected to global trade routes [0][7]. The thread also diverged over whether Hacker News remains Bay Area-centric, with commenters offering conflicting impressions and limited anecdotal/data-based evidence [2][4][9].

3. Research papers using "kidney disappointment" instead of "kidney failure" (scholar.google.com)

380 points · 133 comments · by Alifatisk

Google Scholar blocked the search for papers using “kidney disappointment” instead of “kidney failure,” returning a 403 error because it detected potentially automated queries. [src]

The discussion largely attributes “kidney disappointment” and similar “tortured phrases” to faulty translation or paraphrasing tools used to evade plagiarism detectors, rather than necessarily to modern LLMs [1][2][8]. One commenter traced the phrase to a 2021 paper and suggested synonym substitution for plagiarism avoidance, while others noted comparable examples such as “water goat,” “lactose bigotry,” and an absurd chemistry translation [2][3][7]. Some still suspect broader AI involvement, including automated watermarking or non-LLM systems [4][6][9].

4. Tell HN: Cloudflare silently injects its analytics when you switch nameservers

381 points · 102 comments · by stagas

A user says Cloudflare silently injected an analytics JavaScript snippet into their previously JS-free site after switching nameservers, requiring them to add the site in the Analytics dashboard before disabling it. [src]

The discussion largely concluded that the injection would occur only when Cloudflare’s reverse proxy is enabled (the “orange cloud”), allowing it to terminate HTTPS—not from DNS hosting alone [1][2][7][9]. Commenters criticized this as a potentially surprising, double-opt-out behavior, while Cloudflare explained that Real User Measurement is enabled by default on free plans to power its Observatory product and can be disabled; paid plans are opt-in [4][8]. One commenter characterized the injected analytics as “hostile code” on an otherwise HTML-only, JavaScript-free site and raised broader legal and privacy concerns [0].

5. Models Are Getting Dumber on Purpose (w4g1.dev)

301 points · 167 comments · by hruvhwe

AI labs are deliberately trading memorized factual knowledge for stronger reasoning, relying on retrieval and tools to supply current information while enabling smaller, cheaper models with fewer hallucination-prone stored facts. [src]

The main disagreement is whether models should be assembled from narrowly focused, locally runnable knowledge modules, or remain broadly trained systems whose disparate knowledge improves abstraction and problem-solving; proponents favor configurable assumptions and domains, while critics argue specialization causes tunnel vision and that programming depends on extensive tacit knowledge beyond syntax [0][1][5][6][7][8]. Several commenters suggest specialization belongs in the harness or retrieval layer rather than the weights, with general models adapting to new languages and tasks more effectively than small domain-specific models [1][8]. The post’s claims about benchmarks, hallucinations, and source-based verification were also challenged as outdated or conceptually confused, while another commenter cautioned that

6. Stripe will reportedly acquire OpenRouter for $7B+ (techcrunch.com)

272 points · 186 comments · by zacharyozer

Stripe has reportedly finalized a deal to acquire AI model-routing startup OpenRouter for more than $7 billion, though Stripe declined to comment on the reported transaction. [src]

Commenters see the acquisition as Stripe pursuing an “API rails” strategy for LLMs: abstracting providers, routing around differing reliability and pricing, and potentially creating a token-based payments or subscription layer [0][6][7]. Others question whether a proxy warrants a $7B valuation, suggesting the deal may instead protect Stripe’s growing AI payment volume and counter customer/provider shifts such as OpenAI moving to Adyen [1][3]. Discussion also highlights OpenRouter’s appeal for accessing cheap Chinese models and switching providers easily, alongside concerns about data sovereignty, trust in routing controls, Stripe’s API quality, and acquisition risk for customers [4][5][8][9].

7. What happens when an LLM never sees material beyond fifth grade? (littlelearner-ll.github.io)

239 points · 206 comments · by porridgeraisin

Researchers trained LittleLearner models exclusively on K–5 curriculum data and found that scaling, post-training, and prompting enhanced taught abilities but did not meaningfully unlock capabilities beyond the models’ controlled knowledge boundary. [src]

The discussion broadly agrees that LLMs’ reflexive confidence and agreement can undermine trust, likening them to young children who answer everything confidently, though one commenter notes they still provide useful, accurate information [0][6][7]. A major side debate concerns whether wealth systematically produces entitlement: some argue constant deference creates poor self-regulation [1][3], while others call that portrayal cartoonish and point out that wealthy people still face real-world resistance [2][4][8]. Participants countered with studies and anecdotes alleging links between wealth, entitlement, rule-breaking, and narcissism [9].

8. Qwen 3.8 27B is excellent, but it defaults to overthinking things (simonwillison.net)

266 points · 113 comments · by bilsbie

Qwen 3.8 27B is an impressive, vision-capable open model that runs locally and excels at coding and image analysis, but its default “xhigh” reasoning setting causes excessive overthinking and slow performance, so the author recommends using lower or no reasoning. [src]

Commenters were impressed that a 17GB Qwen model can perform sophisticated work on consumer hardware, calling local-model progress remarkable [0]. However, the main criticism was extreme overthinking: one task took 11 hours on a dual-GPU setup versus about 20 minutes with GPT-5.5, making the model far slower despite its quality [1]. Users attributed this to RL incentives that reward exhaustive checking [2], while suggesting lower reasoning settings, per-message budgets, or intervention through llama.cpp to curb recursive thought [5][7].

9. The AI Credit Resale Economy (vectoral.com)

261 points · 107 comments · by mlenhard

Token brokers are commercializing a growing market for discounted AI credits, reselling startup allowances through marketplaces, proxies, bulk-pricing sites, and online forums, with the author estimating tens of millions of credits available and warning that abuse may prompt provider crackdowns. [src]

Commenters generally see a mix of legitimate unused-credit resale and fraud, with extreme discounts suggesting stolen API keys/cards, automated trials, or substitution with a different model [0]. They also warn that routing prompts through unknown intermediaries can expose private data, manipulate tool calls, or enable attacks on client machines [3][8]. Debate centers on whether the discounts reflect real inference costs or pricing power and VC subsidies: subscriptions may be far cheaper than equivalent API usage, while corporate demand supports high prices despite falling costs [1][2][4][6][7].
