New US visa rules will force foreign students to unlock social media profiles

The newly issued U.S. guidelines now require foreign students and applicants for educational and exchange visas to set their social media profiles to public, enabling U.S. diplomatic staff to scrutinize their online activities. This initiative is designed to identify expressions of hostility towards American citizens, core values, or culture, and to monitor for support of terrorism or antisemitic behavior. Of particular note is the explicit emphasis on detecting anti-Israel sentiment, which critics argue may conflate criticism of Israeli government policies with antisemitism, especially in the context of the ongoing Gaza conflict.

While the policy is positioned as a national security measure, it has sparked concern about its broader implications for privacy and freedom of expression. Commentators worry that the singular focus on Israel-related criticism is neither balanced nor consistently applied to other forms of foreign hostility, potentially resulting in selective enforcement. The requirement for public profiles may prompt international students to curate their online presence strategically, leading to questions about authenticity, self-censorship, and the chilling effect on legitimate political discourse and academic freedom.

The Hacker News community response has been both critical and sardonic, focusing on the tension between security and privacy. Commenters highlighted the double standard in singling out anti-Israel commentary, while others questioned whether similar scrutiny would extend to anti-Chinese or anti-Russian sentiments. Humor and cynicism surfaced as users joked about filling their timelines with “lasagna pics, birthday cakes, and kittens” to appear inoffensive, while technical tips were also shared on managing privacy settings. A recurring theme in the discussion was the perceived overreach of digital surveillance, with many likening the policy to a modern form of gatekeeping that could deter international talent and diminish the appeal of U.S. academic institutions.

Show HN: Workout.cool – Open-source fitness coaching platform

The central story involves the revival and open-sourcing of a modern fitness coaching platform, previously known as workout.lol and now relaunched as Workout.cool. This iteration addresses the failures of its predecessor—specifically, issues around licensing and project abandonment after a change in ownership—by rebuilding the core software, broadening its exercise database, and embracing an MIT license to ensure broad accessibility. The primary focus is toward nurturing a self-sustaining, community-driven platform that meets the needs of diverse users, with the project’s author underscoring a long-standing personal investment in open fitness tools.

Beyond resolving the earlier licensing impasse, the new version is marked by improvements in technical architecture and user experience. The updated application supports multi-language environments, facilitates customized routine creation, and allows users to self-host. However, it remains a work in progress: users have reported various design and usability concerns, particularly in areas such as exercise recommendations and tracking progression. The development team is actively soliciting feedback and contributions, reflecting a clear orientation toward iterative enhancement and collaborative problem-solving—an ethos common to successful open-source initiatives.

Hacker News commenters are largely supportive of the project’s open-source trajectory, highlighting the community’s appreciation for the project’s resilience and transparency. Many users point to the rarity of high-quality open-source fitness applications and express interest in helping to shape its feature set. There is recognition of the inherent challenges in maintaining momentum and code quality after reboots, with some technical critique regarding design and architecture. Notably, the lighthearted comparison of fitness app “before and after stories” underscores the communal, even optimistic, spirit that often characterizes open-source software discussion threads.

Websites are tracking you via browser fingerprinting

Browser fingerprinting has emerged as a powerful, persistent form of online tracking that operates silently and largely outside the user’s control. Recent research led by Texas A&M University demonstrates that websites routinely collect browser-specific signals—such as screen resolution, time zone, and device model—to build unique, stable identifiers. Unlike cookies, which users can delete or manage, these digital “fingerprints” do not disappear with standard privacy tools, making them particularly effective for identifying individuals across browsing sessions and sites.

The study introduced the FPTrace framework, which conclusively connects browser fingerprinting with targeted ad delivery, even in privacy-focused settings. By manipulating browser fingerprint attributes and observing resultant changes in ad system behavior and network records, the researchers proved that major advertising networks actively respond to these fingerprints for user profiling and retargeting. Notably, the persistence of fingerprinting allows tracking to continue even after users clear cookies or signal opt-outs under regulations like GDPR and CCPA, highlighting the limitations of current legal and technical countermeasures.

Hacker News commenters reflected widespread concern and technical insight, with many lamenting the inadequacy of existing privacy solutions. Some users described fingerprinting as “the silent stalker of the internet age,” while others emphasized the placebo effect of clearing cookies or enabling Do Not Track, given fingerprinting’s resilience. The introduction of FPTrace sparked calls for stronger browser-level defenses and regulatory enforcement, and several participants stressed the need for greater transparency and accountability from advertising networks in light of these findings.

Yes I Will Read Ulysses Yes

Richard Ellmann’s 1959 biography of James Joyce is widely regarded as a transformative work that shaped modern perceptions of Joyce by combining meticulous research with compelling narrative. Ellmann’s privileged access to Joyce’s contemporaries and rare materials enabled him to depict Joyce’s complex life and literature with unprecedented clarity and empathy. His narrative approach offered a bridge between biography and literary criticism, making Joyce’s intricate works more accessible to general readers and scholars alike.

As the article notes, Ellmann’s biography emerged at a juncture before academic literary studies became dominated by theoretical and highly specialized critiques. Ellmann’s exhaustive attention to primary sources and storytelling stands in contrast to the contemporary shift towards theory-heavy, less personal scholarship. His methodology and style exemplify an era when literary studies embraced broad, synthesizing perspectives—serving as a cultural touchstone that captured a period where expansive, author-centered literary biographies held institutional prominence.

Hacker News commenters reflect a mixture of admiration and critique, with some viewing Ellmann’s work as a literary “cheat sheet” that renders Joyce less intimidating, while others decry the exclusionary tendencies of academia that followed. There's recognition of Ellmann’s rare ability to humanize a complex figure and commentary on the broader academic evolution toward specialization and insularity. Humorous takes and deep dives into the legacy of biography versus theory show lively engagement, highlighting how Ellmann’s work persists as both a scholarly milestone and a cultural reference point in ongoing debates over how literary studies should be approached.

Game Hacking – Valve Anti-Cheat (VAC)

The article presents an in-depth analysis of Valve’s Anti-Cheat system (VAC), emphasizing its enduring influence and the technical arms race between cheat developers and anti-cheat defenses. The central insight is that despite over two decades of improvements, VAC continues to grapple with balancing effective cheat detection against minimizing false positives, highlighted by historical instances where legitimate users were incorrectly banned due to unforeseen software or driver interactions. The system’s architecture—dynamic DLL anti-cheat modules streamed from servers—remains an engineering feat, but its methodologies are not impervious to scrutiny and circumvention by determined adversaries.

A key technical highlight lies in the walkthrough of dumping and analyzing VAC’s streamed modules using tools like Binary Ninja and x32dbg. The article’s standout contribution is its rigorous explanation of Windows process memory, DLL loading, and code injection, showing how reverse engineers can study anti-cheat internals. Cases of detection failures rooted in the VAC’s sensitivity to third-party software illustrate the complexity of maintaining such a system at scale, especially as cheat mechanisms evolve in sophistication alongside defensive updates.

Hacker News commenters express a notable blend of technical respect and skepticism, underlining that, while VAC has shaped anti-cheat practices and enjoys some community support for prompt engagement with false bans, it is widely viewed as a compromise rather than a comprehensive solution. The discourse frequently references the “cat-and-mouse” dynamic, with several voices emphasizing the inevitability of exploits emerging as long as incentives remain. A recurring sentiment, marked by dry humor and practical advice, points to the use of advanced reverse engineering tools as both a learning opportunity and a testament to the never-ending battle in online game integrity.
