0. I verified my LinkedIn identity. Here's what I handed over (thelocalstack.eu)

1354 points · 462 comments · by ColinWright

LinkedIn identity verification requires users to share extensive biometric and personal data with Persona, a third-party U.S. company that uses the information for AI training and shares it with 17 subprocessors, potentially exposing European users to U.S. surveillance under the CLOUD Act. [src]

The discussion highlights deep skepticism regarding LinkedIn's identity verification process, with users citing historical privacy breaches [2][6] and the "parasitical" nature of data-driven business models [7]. While a Persona representative and industry insiders clarify that data is often deleted quickly and not shared with every listed subprocessor [1][5], others remain "deeply uncomfortable" with the requirement to provide biometric data for basic account access [4]. A significant portion of the debate centers on geopolitical tensions, with some defending the dominance of American tech infrastructure [0] while others argue that the US has actively engineered European digital dependency [3][9].

1. Claws are now a new layer on top of LLM agents (twitter.com)

351 points · 795 comments · by Cyphase

Andrej Karpathy describes "Claws" as a powerful new orchestration layer for AI agents while warning of significant security risks in large, unvetted implementations like OpenClaw. [src]

The discussion defines "claws" as persistent, asynchronous LLM agents that run on a schedule (like "cron-for-agents") with broad permissions to access credentials, email, and the web [0][3]. While some users remain skeptical of their utility or see them as "vanity AI" [5][7], others envision practical applications such as automated media archiving [6].

A significant portion of the debate focuses on the rapid shift from fearing "Skynet" to granting AI autonomous internet access [1][8]. Critics argue that security concerns are often "overdone" by bureaucratic "policy people" [2], while proponents of safety suggest technical guardrails, such as requiring one-time passwords (OTPs) before an agent can execute high-risk actions [4].

2. Why is Claude an Electron app? (dbreunig.com)

392 points · 402 comments · by dbreunig

Despite the rise of AI coding agents, Anthropic continues to use the Electron framework for its desktop app because agents still struggle with the "last mile" of development, maintenance, and cross-platform support required for native applications. [src]

Anthropic engineers chose Electron to leverage their team's prior expertise and ensure feature parity across web and desktop platforms, though they acknowledge this involves performance tradeoffs [0]. Critics argue that a multi-billion dollar company should prioritize native performance over "dumpy" UX and bloated dependencies [6][7], noting the irony that AI tools—which claim to make porting code effortless—are not being used to move away from JavaScript [9]. Meanwhile, some users defend the choice as a pragmatic business decision, dismissing complaints about RAM usage as "HN-sniping" [3][8].

3. What not to write on your security clearance form (1988) (milk.com)

465 points · 207 comments · by wizardforhire

After a 12-year-old’s homemade code key triggered a massive FBI spy investigation in 1943, a security officer later forced him to omit the incident from his clearance application to avoid a permanent bureaucratic rejection. [src]

The security clearance process is often viewed as a "game" where applicants are frequently encouraged—sometimes even by security officers themselves—to omit or lie about past indiscretions to fit into rigid bureaucratic categories [0][4][6]. While the system is intended to identify blackmail risks like debt or substance abuse, critics argue that forcing applicants to lie actually creates new vulnerabilities for extortion [5]. There is a notable disparity in enforcement, where functional alcoholism is often overlooked while even minor, historical drug use can lead to immediate disqualification [1][9].

4. CXMT has been offering DDR4 chips at about half the prevailing market rate (koreaherald.com)

225 points · 227 comments · by phront

Chinese chipmaker CXMT is challenging Samsung and SK hynix by offering legacy DDR4 DRAM at half the market rate, leveraging state subsidies to gain market share while simultaneously expanding into high-end HBM3 production to compete in the AI memory sector. [src]

The entry of Chinese firms like CXMT into the DRAM market is seen as a strategic payoff for decades of state subsidies, potentially allowing them to dominate the sector through aggressive pricing while Western incumbents focus on high-margin AI chips [0][2]. While some argue that low prices are a win for consumers and that domestic industries simply shift toward higher-value niches [1][5][7], others warn that this leads to a dangerous loss of production capacity and innovation [3]. Critics emphasize that becoming dependent on a single, potentially unfriendly supplier creates significant geopolitical risks, as specialized domestic facilities cannot easily replace mass-market capacity during a trade war or conflict [6][9].

5. EU mandates replaceable batteries by 2027 (2023) (environment.ec.europa.eu)

228 points · 178 comments · by cyrusmg

The EU's new Batteries Regulation mandates that by 2027, consumers must be able to remove and replace portable batteries in electronic products. The law also introduces strict carbon footprint limits, recycling targets, and due diligence requirements to ensure a sustainable and circular battery life cycle. [src]

Proponents of the EU mandate argue it is a necessary step against planned obsolescence and the "mountain-sized piles" of toxic e-waste generated by non-removable designs [0]. Critics, however, contend that modern batteries are more durable than their predecessors and that integrated designs allow for sleeker, water-resistant devices with better component density [1][4][5]. While some users value the convenience of carrying spare batteries to eliminate charging downtime [8], others argue that the useful life of a device is often limited by CPU and RAM obsolescence rather than battery degradation [5].

6. How Taalas “prints” LLM onto a chip? (anuragk.com)

270 points · 132 comments · by beAroundHere

Startup Taalas has developed a fixed-function ASIC chip that "hardwires" Llama 3.1 8B weights directly into silicon, achieving 17,000 tokens per second by eliminating the memory bandwidth bottleneck found in traditional GPU-based inference systems. [src]

The transition from software-based LLM inference to dedicated hardware is viewed by some as an inevitable evolution similar to the history of GPUs [0][8]. While technical analysis suggests that packing billions of coefficients into transistors is highly feasible through quantization and block compression [7], critics argue that the rapid pace of AI development makes non-rewritable chips impractical for models that become outdated in weeks [4][6]. Despite these concerns, there is significant interest in the potential for ultra-efficient, "plug-and-play" inference ASICs in form factors like USB-C drives or integrated "AI cores" within consumer electronics [1][2][3][5][9].

7. Personal Statement of a CIA Analyst (antipolygraph.org)

226 points · 156 comments · by grubbs

A former CIA analyst details her career-long struggle with the polygraph, describing how the test's unreliability and the aggressive tactics of examiners led her to eventually refuse further testing and resign from her position as a defense contractor. [src]

The discussion centers on the CIA's continued use of polygraph tests, which many users dismiss as pseudoscience akin to the agency's historical interest in telekinesis [0][2]. While critics argue the tests lack scientific validity, others contend they are effective "pressure cookers" designed to intimidate candidates into confessions through the fear of detection [4][9]. Commenters also debated the ethics and practicality of the agency's rigid hiring standards, ranging from amusement at the idea of an analyst's emotional vulnerability to defense of disqualifying candidates for petty theft [3][6][7].

8. Show HN: Llama 3.1 70B on a single RTX 3090 via NVMe-to-GPU bypassing the CPU (github.com)

300 points · 80 comments · by xaskasdf

NTransformer is a high-efficiency C++/CUDA inference engine that enables running Llama 3.1 70B on a single 24GB RTX 3090 by bypassing the CPU to stream model layers directly from NVMe storage to the GPU. [src]

This project demonstrates running a 70B model on a single GPU by bypassing the CPU to load data directly from NVMe, though users note the resulting speed of 0.2 tokens per second is too slow for interactive use [0][1]. While some argue that a well-quantized smaller model or standard CPU/RAM inference might offer better latency-quality tradeoffs [0][1][2], others suggest this approach is ideal for cost-effective, non-interactive batch workloads like automated content pipelines [6]. The discussion also explores theoretical optimizations, such as using multi-tier Mixture of Experts (MoE) to balance weights between VRAM, RAM, and NVMe, or utilizing technologies like GPUDirect and DirectX APIs to further streamline data transfers [3][5][7][9].

9. Acme Weather (acmeweather.com)

234 points · 141 comments · by cryptoz

Acme Weather: Title: Acme Weather

URL Source: https://acmeweather [src]

The discussion reflects significant skepticism regarding Acme Weather’s $25/year subscription model and its utility in a market saturated with free, high-quality alternatives [1][2][6][9]. Many users expressed frustration over the app's US-only availability and the lack of specific features like "feels like" forecasts or historical data for planning [0][3][4]. While some appreciate the team's "depth of thought" and expertise [8], others argue that local government-funded apps often provide superior data and features for free [7].

10. AI uBlock Blacklist (github.com)

262 points · 113 comments · by rdmuser

This GitHub repository provides a manually curated blacklist for uBlock Origin to block AI-generated content farms and "slop" websites. It aims to improve search reliability by filtering out low-quality, automated articles that lack human experience or contain dangerous hallucinations. [src]

The discussion centers on the utility and ethics of blocking AI-generated content, with some users preferring the "character" of non-native or poorly translated text over generic "AI slop" [2][5][6]. However, critics highlight the maintainer's hostile attitude toward removal requests and the potential for "infallible" lists to unfairly penalize non-English speakers or legitimate sites [0][1][9]. While some suggest more grounded alternatives focused on content farms [4], others debate the necessity of adblockers in general or the terminology used to describe them [3][7][8].

11. Andrej Karpathy talks about "Claws" (simonwillison.net)

283 points · 74 comments · by helloplanets

Andrej Karpathy highlights "Claws" as an emerging layer of the AI stack, describing these systems as advanced LLM agents that run on personal hardware to handle complex orchestration, scheduling, and persistent task execution. [src]

The discussion centers on a debate over "original sourcing" and self-promotion, sparked by a blog post summarizing Andrej Karpathy's comments instead of linking to the original source [0][1]. Critics argue the author, Simon Willison, engages in excessive self-promotion and "link farming," noting that over 10% of his 13,000+ comments link back to his own site [1][2][7]. In his defense, Willison and several supporters clarify that he did not submit this specific post and argue his "link blog" adds value by contextualizing industry trends for those not on social media [4][6][9]. While some users find his frequent presence "slop," others defend him as an essential independent voice in the AI space [3][5][8].

12. zclaw: personal AI assistant in under 888 KB, running on an ESP32 (github.com)

213 points · 117 comments · by tosh

zclaw is an open-source, C-based personal AI assistant for ESP32 microcontrollers that fits within an 888 KiB firmware budget. It supports natural language tool composition, GPIO control, scheduled tasks, and persistent memory while integrating with providers like Anthropic, OpenAI, and OpenRouter. [src]

While some users find the project "glorious" for its potential to give IoT devices more agency [9], many commenters expressed disappointment that the 888 KB footprint is merely an API wrapper for cloud-based LLMs rather than a local inference engine [0][1][5][8]. Critics argue the binary size is actually unimpressive for a C-based client, noting that much more complex software like *Doom* was smaller [7][8]. Discussion also touched on the security risks of the project's "curl to bash" installation pattern [4] and questioned the practical utility of such a minimal assistant [2][6].

13. Cloudflare outage on February 20, 2026 (blog.cloudflare.com)

180 points · 118 comments · by nomaxx117

On February 20, 2026, a buggy automated cleanup task caused a six-hour Cloudflare outage by unintentionally withdrawing BGP routes for approximately 1,100 Bring Your Own IP (BYOIP) prefixes, rendering some customer services and the 1.1.1.1 website unreachable from the internet. [src]

Recent discussions suggest a consensus that Cloudflare’s reliability has declined significantly, shifting from a five-year period of stability to multiple disruptions in the last six months [0][1][3]. Internal accounts and observations attribute this to a toxic leadership culture, a reckless "AI-first" push, and the departure of key technical leaders like former CTO John Graham-Cumming [4][7][9]. Furthermore, critics point to a decline in technical quality, citing nonsensical code explanations in official blog posts and "vibe coding" practices that prioritize shipping speed over system integrity [2][4][8].

14. What Is OAuth? (leaflet.pub)

217 points · 78 comments · by cratermoon

OAuth creator Blaine Cook explains that the protocol is essentially a standardized way to securely delegate access by sending a multi-use secret to a third party with a user's consent. [src]

[1] > Hopefully, this post helps clear that up! Thanks, it did not. OAuth and OpenID Connect are a denial of service attack on the brains of the humans who have to work with them. [2] The thing about OAuth is that it’s really very simple. You just have to grasp a lot of very complicated details (that nobody explains) first before it becomes simple. [3] This is the only thing you need to know about OAuth. As FYI ...Eran Hammer is the author of OAuth 1.0 and original editor of the OAuth 2.0 spec. [1] "...Eran Hammer resigned from his role of lead author for the OAuth 2.0 project, withdrew from the IETF working group, and removed his name from the specification in July 2012. Hammer cited a conflict between web and enterprise cultures as his reason for leaving, noting that IETF is a community that is "all about enterprise use cases" and "not capable of simple". "What is now offered is a blueprint for an authorization protocol", he noted, "that is the enterprise way", providing a "whole new frontier to sell consulting services and integration solutions". In comparing OAuth 2.0 with OAuth 1.0, Hammer points out that it has become "more complex, less interoperable, less useful, more incomplete, and most importantly, less secure". He explains how architectural changes for 2.0 unbound tokens from clients, removed all signatures and cryptography at a protocol level and added expiring tokens (because tokens could not be revoked) while complicating the processing of authorization. Numerous items were left unspecified or unlimited in the specification because "as has been the nature of this working group, no issue is too small to get stuck on or leave open for each implementation to decide." David Recordon later also removed his name from the specifications for unspecified reasons. Dick Hardt took over the editor role, and the framework was published in October 2012. David Harris, author of the email client Pegasus Mail, has criticised OAuth 2.0 as "an absolute dog's breakfast", requiring developers to write custom modules specific to each service (Gmail, Microsoft Mail services, etc.), and to register specifically with them."

15. macOS's Little-Known Command-Line Sandboxing Tool (2025) (igorstechnoclub.com)

209 points · 81 comments · by Igor_Wiwi

macOS's Little-Known Command-Line Sandboxing Tool (2025): Title: sandbox-exec: macOS's Little-Known Command-Line Sandboxing Tool

URL Source: https://igorstechnoclub [src]

While `sandbox-exec` remains functional for some, it has been officially deprecated for nearly a decade in favor of the "App Sandbox" feature [0][3]. Users note that the tool functions more like a high-level `seccomp` than a true containerized sandbox, leading to frustration over its poor documentation and the lack of Linux-style overlay mounts on macOS [2]. Despite its deprecated status, the tool persists because Apple still relies on it for first-party applications, though some developers have begun building modern UIs and wrappers around it for sandboxing coding agents [5][7][9].

16. Parse, Don't Validate and Type-Driven Design in Rust (harudagondi.space)

220 points · 59 comments · by todsacerdoti

This article explores type-driven design in Rust, advocating for "parsing" data into specialized newtypes—like `NonZeroF32` or `NonEmptyVec`—rather than using simple validation functions. This approach ensures illegal states are unrepresentable and moves error handling to the earliest possible stage of execution for more robust code. [src]

The discussion centers on the "Parse, Don't Validate" philosophy, which advocates for "correct by construction" data types that make illegal states unrepresentable [3][6][9]. While proponents highlight the safety of encoding invariants into types—sometimes extending to advanced dependent typing to prevent out-of-bounds errors or division by zero [1]—critics point out that this can lead to an explosion of incompatible types and friction when adapting to real-world changes [0][7]. There is a noted tension between this approach and the Clojure-style philosophy of using a few flexible data structures with many functions [0][4], as well as practical concerns regarding how to handle operations like addition that may not preserve the original type's invariants [5][8].

17. EDuke32 – Duke Nukem 3D (Open-Source) (eduke32.com)

196 points · 71 comments · by reconnecting

EDuke32 is a free, open-source game engine and source port that brings *Duke Nukem 3D* to modern operating systems with enhanced graphics, scripting extensions, and high-resolution support. [src]

Commenters fondly recall *Duke Nukem 3D* for its "rage-inducing" weaponry and the modding accessibility of the Build Engine, which fostered a vibrant scene of custom maps and LAN parties [0][2]. While some view it as less prestigious than *Doom* or *Quake*, they acknowledge its high "fun factor" and the enduring appeal of its combat [1][8]. Discussion also highlights modern ways to play, including Apple Silicon ports and WASM demos, alongside a desire for AI to modestly improve classic gameplay without destroying its original "flair" [3][4][5].

18. Meta Deployed AI and It Is Killing Our Agency (mojodojo.io)

146 points · 105 comments · by zenincognito

Digital marketing agency Mojo Dojo reports that Meta’s automated AI security systems are systematically banning its employees' accounts despite successful identity verification, creating an "absurd" loop with no human recourse that prevents the agency from managing millions in ad spend for its clients. [src]

Commenters are highly skeptical of the linked article, noting that it lacks specific evidence of AI involvement and appears to be LLM-generated "clickbait" [0][5][7]. Despite this, the thread highlights a consensus that major tech platforms have become increasingly hostile to users through automated bans and impossible verification loops that lack human oversight [1][2][3]. Some users argue that these "undefined behaviors" in corporate systems will only worsen as companies replace internal staffing with AI [1][6].

19. LibreOffice blasts OnlyOffice for working with Microsoft to lock users in (neowin.net)

134 points · 109 comments · by XzetaU8

We couldn't summarize this story. [src]

The discussion centers on the trade-off between LibreOffice’s "dated" UI and OnlyOffice’s modern aesthetics, with users debating whether the classic menu style is a productivity boon or an ancient relic [0][1][2][6]. While OnlyOffice is praised for its lighter feel and better compatibility with Microsoft formats, some users report critical stability issues, such as inexplicable data loss [3][4]. Significant concerns are also raised regarding OnlyOffice’s corporate transparency and Russian origins, leading some developers to label their upstream code as "untrusted" [4][9].
