GPTZero's analysis of 4841 papers accepted for NeurIPS 2025 has identified at least 100 confirmed hallucinations in citations across 51 papers. These instances of "vibe citing," where generative AI fabricates or misrepresents sources, were missed by the conference's peer review process, which typically involves three or more reviewers per paper. The article highlights that the increasing volume of submissions to major AI conferences like NeurIPS, driven by generative AI and publication pressure, has strained review pipelines, leading to oversight issues. GPTZero's Hallucination Check tool is presented as a solution to assist authors, reviewers, and editors in identifying these citation errors.
The NeurIPS 2025 conference had an acceptance rate of 24.52%, meaning these papers containing hallucinations were among the top 24.52% of submissions. The article notes that NeurIPS's policy considers hallucinated citations grounds for rejection or revocation. GPTZero defines a hallucinated citation as one that likely stems from generative AI, characterized by fabricated or amalgamated source details, distinguishing them from common human errors. The study aims to illuminate vulnerabilities in the peer review system rather than criticize specific individuals.
HN commenters expressed significant concern over the findings, foreseeing a negative impact on scientific research and an exacerbation of existing issues like data falsification. There was a strong sentiment that the prevalence of such errors, including fabricated author names like "Firstname Lastname," indicates a breakdown in the peer review process and a potential overreliance on AI tools by researchers. Some users suggested that the ease with which these hallucinations were identified by GPTZero points to a lack of thoroughness in early-stage screening by reviewers.
The discussion also touched upon the broader systemic issues within academic publishing, including the "publish or perish" culture, the difficulty of ensuring reproducibility, and the potential for AI to be used in generating not only papers but also code and reviews. Several comments questioned the effectiveness of current peer review mechanisms, with some advocating for more rigorous verification of citations and code, while others pointed out that even AI detection tools themselves could be prone to error. There was also a call for greater transparency in AI usage by researchers and a desire for an analysis of hallucination rates in rejected papers to understand the scope of the problem.

The article critiques the oversimplified and commercialized perception of design thinking, asserting that it's not a magical formula for innovation but rather a way to leverage inherent design expertise. It highlights the author's intention to share key design thinking books that delve into the core principles and values of design, rather than just methodologies or toolkits. These books are presented as essential for understanding the foundational aspects of design that enable effective application of any design thinking process.
The author introduces an updated list of recommended books and a paper that explore design from various perspectives, emphasizing that learning these core principles is crucial for both designers and non-designers. The selected works aim to enhance creative idea generation and analytical thinking by focusing on the collaborative and fundamental aspects of design practice, moving beyond mere procedural steps to cultivate a deeper appreciation for creative practice.
HN commenters offered a range of additional book recommendations and perspectives on design thinking. Several users suggested foundational texts like "Don't Make Me Think" by Steve Krug and "Creative Confidence" by Tom and David Kelley, emphasizing their relevance and practical insights. There was also a sentiment that design thinking is sometimes overhyped or misunderstood, with some arguing for a broader systems thinking approach or criticizing its commercialization.
A notable point of discussion was the perceived academic nature of some design literature, with one user finding "The Design of Everyday Things" to be theoretical and less practical than expected. Conversely, others defended its importance in bridging human behavior and design. The criticism of "design thinking" as a potentially misleading or ineffective framework was present, with some users suggesting it's a subset of other disciplines or a way to sell consulting services.

Attempts to fetch the content resulted in a timeout or a connection error, preventing its analysis.
The discussion centers on SSH's behavior, particularly its packet transmission rate and the reasons behind it. A significant topic is the "keystroke timing obfuscation" feature introduced in SSH, which adds "chaff" packets to make it harder to infer typing patterns. Some commenters found this feature unnecessary or even detrimental to performance, suggesting it should be optional or disabled in certain environments.
Several technical solutions for packet reduction and latency improvement were proposed, including using `TCP_CORK` or disabling `TCP_NODELAY`. The author's use of an LLM (Claude) for debugging and its perceived over-reliance on certain phrases like "smoking gun" was also a point of discussion. A recurring theme was the unsuitability of SSH for high-performance applications like games, with alternatives like Telnet or specialized SSH versions being mentioned. The overall sentiment suggests a trade-off between security features and performance, and whether certain security measures are always appropriate or beneficial.

The article explains the practical differences between Tree-sitter and Language Servers (LSP) from a user's perspective, acknowledging the author's limited in-depth knowledge of their inner workings. Tree-sitter is presented as a fast, error-tolerant parser generator ideal for syntax highlighting in text editors, as it can handle code in syntactically invalid states. It also allows for robust querying of parse trees, offering a more reliable alternative to regex for identifying syntax elements.
Language Servers, on the other hand, analyze programs and provide smart programming assistance to text editors via the Language Server Protocol (LSP). This solves the N x M problem by standardizing communication, enabling features like go-to-definition and code completion. LSPs leverage compiler toolchains for semantically correct answers, which is crucial for disambiguating code constructs that simple parsers might struggle with. The article notes that LSPs *can* be used for syntax highlighting, but Tree-sitter is often preferred for its speed and robustness in this specific task.
The discussion reveals a consensus that both Tree-sitter and LSP are valuable tools, often complementary rather than mutually exclusive. Several users express frustration with the limited availability of Tree-sitter parsers for certain languages, while acknowledging its power for structured editing and syntactic analysis. A key point raised is the potential latency and instability introduced by relying solely on LSP for syntax highlighting, with suggestions for a hybrid approach where Tree-sitter handles immediate lexical coloring and LSP provides slower, semantic embellishments.
Furthermore, experienced developers clarify that LSPs are not necessarily "heavy" but rather designed for a broad range of IDE features, including semantic highlighting which requires deep language understanding beyond syntactic parsing. The distinction between a parser (like Tree-sitter) and a full semantic analysis engine (often powering LSPs) is highlighted, with the former focusing on structure and the latter on meaning, type resolution, and context. This semantic understanding is considered essential for advanced IDE features like renaming across a codebase or precise symbol navigation.

This article explores the creation of various optical illusions using CSS. The author demonstrates how to replicate classic illusions like the Poggendorff, Cornsweet, and Ebbinghaus illusions, among many others, by leveraging CSS gradients, pseudo-elements, and blend modes. The illusions are categorized into those that are static but appear to move, and those that actually involve motion. Many of the demos are interactive, allowing users to mouse over them to reveal the underlying CSS construction or stop the animation.
The illusions are presented as a collection, with each section explaining the illusion's principle and the CSS techniques employed. These range from simple line and shape manipulations to more complex gradient-based effects that trick the eye into perceiving non-existent shapes, colors, or movements. The article aims to showcase the creative potential of CSS for generating visually engaging and mind-bending effects.
The discussion expresses appreciation for the article, with users noting their interest in incorporating these illusions into UIs or comparing them to past experiments in tools like Excel. Some commenters highlight specific illusions, such as the "Color Fan" appearing to rotate faster when not directly viewed, and others identify the "dots appearing only while (not) focused" as "extinction illusions," providing specific names and references for these phenomena.
A key point raised is the perspective that these demonstrations are as much about showcasing interesting CSS techniques as they are about optical illusions themselves. One commenter notes a specific difficulty in "seeing through" certain illusions, particularly induced gradients, suggesting that covering parts of the screen helps them perceive the reality. The potential for using these illusions in applications like CAPTCHAs is also mentioned.
