The article argues that Apple's introduction of icons to every menu item in macOS "Tahoe" is a detrimental design choice. The author contends that the core purpose of an icon is differentiation, and by adding icons to everything, they lose their ability to stand out and aid in faster recognition. The piece highlights inconsistencies in icon design, even for basic functions like "New" or "Open," across different applications and even within the same app. The author also points out issues with icon reuse for distinct actions, overly detailed icons that are illegible at small sizes, and confusing metaphors that fail to clearly represent their intended actions.
Furthermore, the article criticizes Apple's reliance on vector fonts for tiny icons, leading to blurry and mediocre rendering, and the misuse of system elements and text within icons. The author asserts that the principles outlined in the 1992 Macintosh Human Interface Guidelines remain relevant because they are based on human perception and cognition, which haven't changed. Ultimately, the article concludes that Apple's attempt to iconize every menu item is an impossible task, and even within that goal, the execution is flawed, demonstrating a disregard for established design principles.
A significant portion of the discussion revolves around the perceived irony of the article's author, who criticizes design flaws while employing distracting animated snow on their own website, which many users found to hinder readability. Several commenters expressed agreement with the article's critique of Apple's UI decisions, with some noting that older operating systems, like Windows 2000/XP Classic or older macOS versions, are often considered to have better UI design. A few users, however, offered an unpopular opinion, stating they find the icons helpful for faster parsing of menus, though they acknowledged potential for improvement.
There was also a broader commentary on Apple's design direction, with some users lamenting the perceived decline in user needs, usability, and consistency in recent macOS and iOS releases. Some attribute these issues to a lack of strong leadership, internal departmental conflicts, or a shift away from user-centric design principles. The discussion also touched upon the increasing display density and how it might affect the relevance of older UI guidelines, though the article's core principles regarding human perception were defended.

This article reviews the major trends and developments in the database industry during 2025. PostgreSQL continued its dominance, with its v18 release introducing asynchronous I/O and skip scan support, and significant activity from companies building on its ecosystem. The emergence of distributed PostgreSQL projects like Multigres and Neki, along with major cloud vendors offering their own PostgreSQL DBaaS solutions, highlights this trend.
Another key theme was the widespread adoption of Anthropic's Model Context Protocol (MCP), enabling LLMs to interact with databases. However, this integration raised security concerns regarding data access and the potential for misuse by AI agents. The article also covered the MongoDB v. FerretDB lawsuit, the competitive landscape of new file formats challenging Parquet, a wave of acquisitions and funding rounds, and notable company and project closures. Finally, it touched upon Larry Ellison's personal and professional milestones in relation to Oracle's performance.
Commenters expressed agreement with the author's skepticism regarding MCP security, emphasizing the conflict with the principle of least privilege and drawing parallels to SQL injection vulnerabilities. Several users pointed out omissions in the article, such as the lack of mention for SQLite, DuckDB, and time-series databases, while also questioning the article's focus on feature-richness over user base popularity for PostgreSQL compared to MySQL. The acquisition of Gel (formerly EdgeDB) by Vercel was clarified as a team acquisition rather than a product one, with the project being sunset. There was also commentary on the underrepresentation of Oracle and Microsoft SQL Server in the review, despite their significant market share.

The article investigates unusual Border Gateway Protocol (BGP) anomalies observed during a significant internet outage in Venezuela. The author, from an offensive security perspective, focuses on BGP, the routing protocol that directs internet traffic. Analysis of Cloudflare Radar data for CANTV (Venezuela's state-owned telecom) revealed anomalies on January 2nd, including unusual Autonomous System (AS) paths where CANTV was unexpectedly included, and a spike and dip in BGP announcements. The investigation further utilized raw BGP data from ris.ripe.net to identify specific IP address blocks being routed through these anomalous paths, which were found to belong to Dayco Telecom, a hosting provider. The article notes that some of these IP ranges host critical infrastructure like banks and email servers.
The author posits that these BGP anomalies, particularly the repeated prepending of CANTV's AS number in the AS path, could be a deliberate tactic to reroute traffic through a controlled intermediary for intelligence gathering, or potentially to make traffic less likely to traverse CANTV's network. While acknowledging that BGP anomalies are common and the exact intent remains unclear, the article concludes that "BGP shenanigans" were occurring during the timeframe of the Venezuela blackout, and suggests further analysis of the available public data is warranted.
HN commenters engaged in speculation about the potential capabilities and implications of the observed BGP anomalies. Several users questioned what other cyber capabilities might have been employed or considered by the US military during the operation, with one user suggesting that similar BGP anomalies might be looked for around other strategically important regions. A primary theory among commenters was that the anomalies facilitated eavesdropping on internet traffic by rerouting it through an intermediary like Sparkle, although some expressed uncertainty about the technical feasibility and implications of such an attack.
There was a debate about whether the anomalies were a deliberate malicious act or a consequence of the broader event. Some commenters proposed alternative theories, suggesting that the BGP anomalies could be a result of power outages or network disruptions, rather than the cause. One commenter provided a counter-argument that AS prepending by CANTV is a common traffic engineering practice and that the observed BGP route leak might have been a misconfiguration, suggesting no immediate evidence of nefarious activity. The discussion also touched upon the broader implications of cyber warfare, the security of internet infrastructure, and the potential for future such incidents.

DoNotNotify is an Android application designed to provide users with granular control over their notifications. It emphasizes a privacy-first approach, processing all notification data offline without any servers or tracking. The app allows users to create powerful rules based on app names, message content, or regex patterns to intelligently block unwanted notifications, such as promotional messages, while ensuring that important alerts are still delivered.
The application boasts a simple, efficient, and clean interface. DoNotNotify is committed to user privacy, explicitly stating that it does not collect or share any personal information, and its design principle is to process data locally on the device.
The discussion reveals a widespread frustration with app developers who push irrelevant or promotional notifications, often through obscure notification categories that are difficult for users to manage. Many users resort to simply disabling all notifications for certain apps or even putting their phones on permanent silent mode to mitigate this issue. Several commenters noted the existence of similar functionality in other apps like FilterBox and BuzzKill, and some pointed out that native Android features, like "Notification Organizer," are insufficient as they only deprioritize rather than block notifications.
There is a strong sentiment that app stores should enforce stricter rules on notification practices, penalizing apps that fail to use correct notification categories or that mix promotional content with essential alerts. The potential for future enhancements, such as LLM-filtered notifications, was also discussed, alongside comparisons to iOS's more restricted notification control capabilities. The privacy-focused, offline processing of DoNotNotify was highlighted as a key benefit.

Tailsnitch is a security auditing tool designed for Tailscale configurations. It scans a Tailscale network (tailnet) for over 50 common misconfigurations, overly permissive access controls, and violations of security best practices. The tool supports authentication via API keys or OAuth, with OAuth being the preferred method for its scoped and auditable access. Tailsnitch can be run interactively, filtered by severity or category, and can even attempt to fix some issues automatically or provide direct links for manual intervention. It also offers features for generating SOC 2 audit reports with Common Criteria mappings and allows users to define an ignore file for accepted risks.
The tool can be installed via Go or downloaded as a release. It performs a comprehensive security audit, covering categories like Access Controls, Authentication & Keys, Device Security, Network Exposure, SSH Rules, and Logging & Admin. Tailsnitch can also be integrated into CI/CD pipelines to catch security regressions and can output findings in JSON or CSV formats. The output includes detailed explanations of findings, potential remediation steps, and links to relevant Tailscale documentation.
Several users expressed enthusiasm for Tailsnitch, with one user noting it addresses a "low-level anxiety" about complex ACL configurations as their tailnet grows. The ability to run the tool in CI/CD was highlighted as a significant benefit for catching regressions. There was a practical concern raised about the security implication of instructing macOS users to strip quarantine attributes from downloaded binaries. Users also inquired about potential future features, such as custom check creation and compatibility with Headscale.
A discussion point emerged regarding whether Tailscale itself should offer such auditing functionality natively. One user suggested that Tailscale could benefit from providing a built-in "scan now" button or integrating similar checks directly into their platform. Another user clarified their understanding of Tailsnitch as a configuration linter, contrasting it with a desire for real-time audit logs of specific user actions like SSH connections. The tool's existence was also seen by some as validating potential security concerns as Tailscale networks scale beyond small, highly competent teams.

David Rosen, co-founder of Sega and a significant figure in the arcade game industry, has passed away at the age of 95. After serving as a US Air Force pilot in Korea, Rosen stayed in Japan and established Rosen Enterprises in 1954, initially importing photo booths and coin-operated machines. This venture merged in 1965 with Nihon Goraku Bussan to form Sega, which evolved from importing games to designing its own successful arcade titles. Rosen was instrumental in Sega's expansion into home consoles, overseeing the establishment of Sega of America and the success of the Mega Drive (Genesis), notably marketing it towards a teenage audience with a strategy that contrasted with Nintendo's family-friendly approach.
Rosen's leadership was characterized by his ability to identify and hire talented individuals, such as Hayao Nakayama, who played a crucial role in Sega's rise as an industry leader through its innovative arcade games and successful console launches. Despite Sega's eventual decline in the home console market with the rise of PlayStation, its arcade dominance persisted. Rosen remained a director until 1996, and his influence on the video game industry, particularly in its early Japanese development and global console competition, is widely recognized.
The discussion centered on acknowledging David Rosen's passing and his profound impact on the video game industry, with many users expressing gratitude for his contributions. There was notable surprise and interest in learning that he co-founded Sega itself, not just Sega of America, and that "Sega" is a portmanteau of "Service Games." Several commenters highlighted Sega's stellar arcade output and its position as a leading game company, with some reminiscing about iconic advertising slogans like "Genesis does what Nintendon't." One user recommended the book "Console Wars" for those interested in Rosen's story and Sega's history. A minor point of discussion also arose regarding the perceived inconsistency in how submissions gain traction on the platform.
