Ditching Obsidian and building my own

The central insight of the article is that building a custom personal knowledge management system (PKMS) can restore control, privacy, and adaptability for users frustrated with commercial solutions like Obsidian. The author, after facing limitations related to feature paywalls and privacy with proprietary PKMS platforms, chose to create a self-hosted alternative using the open-source tool Directus. This decision enabled a setup tailored to personal needs while eliminating recurring costs and third-party data dependence.

Exploring technical and philosophical dimensions, the author describes the build process as both technically approachable and deeply empowering. The resultant system fosters a more intentional relationship with information, emphasizing that personal note-taking tools should prioritize security, data ownership, and longevity. By moving away from commercially driven ecosystems and subscription models, the author demonstrates that open-source frameworks now make it feasible for individuals with moderate technical skills to design robust, sustainable alternatives.

Hacker News commenters largely echoed these privacy and ownership concerns, with many expressing dissatisfaction over perceived openness versus real accessibility in tools like Obsidian—particularly its monetized mobile access. A consistent theme was a preference for pragmatic, do-it-yourself approaches to digital knowledge management, often shared with humor and candid personal anecdotes. The discussion highlighted a tension between customization overhead and system usability, but also showcased enthusiasm for exploring open-source options and the sense of autonomy gained by building one’s own tools.

What do wealthy people buy, that ordinary people know nothing about? (2015)

The central theme in the discussion is that the difference wealth creates is not primarily in the products themselves, but in enhanced access, experiences, and opportunities. While both the ultra-wealthy and ordinary people may share the same brands of technology or appliances, with status goods serving as a visible differentiator, what truly distinguishes the lifestyles of the very rich are bespoke solutions and privileges that are often invisible to outsiders. One illustrative anecdote describes a wealthy parent constructing a professional-grade athletic track and securing elite coaching for his child during a pandemic—an example of problem-solving on a scale unattainable to most.

Further insights reveal nuances in how the wealthy pursue “quiet luxury,” opting for unbranded, high-quality goods and services that subtly signal exclusivity without overt displays of wealth. This focus on understated consumption aligns with broader trends in luxury, where access to exceptional services, privacy, and personalized experiences takes precedence over conspicuous branding. Access to tailored solutions, such as custom healthcare, legal insulation, and unique educational opportunities, is highlighted as a domain where wealth’s full impact is most acutely felt, setting the ultra-wealthy apart from even the upper middle class.

Hacker News commenters focused on how status goods and exclusive services operate as both social signals and functional advantages for the ultra-rich. Several users reflected on the sociological role of status symbols, noting that, while luxury products are often visible markers, the truly meaningful disparities lie in the access and insulation wealth provides. Moderation and self-awareness appeared in the discourse, with some pointing out the irony that the wealth gap is less about material excess and more about systemic privileges and the ability to shape environments, experiences, and outcomes to one’s precise needs.

Show HN: I modeled the Voynich Manuscript with SBERT to test for structure

The article describes a novel application of natural language processing to the Voynich Manuscript, a famously undeciphered 15th-century text. By employing SBERT embeddings and KMeans clustering, the author investigates whether the manuscript exhibits structured linguistic patterns, focusing on syntax rather than semantic content or decryption. This approach demonstrates that, after normalizing words to their root forms and analyzing by manuscript section, there are observable and consistent syntactic patterns, suggesting the manuscript may indeed represent a structured—though unknown—language.

Additional analysis involves stripping away frequent suffix-like endings to isolate root forms before vectorizing and clustering the text. The author’s methodology, while exploratory, illustrates NLP’s flexibility for processing even highly atypical and controversial corpora. They position this project as a learning experience and a foundation for further work, welcoming feedback from experts to refine or extend the modeling process. While the results do not provide translation or meaning, they deliver evidence of non-random structure within specific manuscript sections, contributing new data points to the long-running debate on the manuscript's nature.

Hacker News commenters generally appreciate the technical creativity and educational intent of the project, with particular emphasis on the value of structural modeling as opposed to futile decryption efforts. Some skepticism remains regarding the practical implications of these findings, as echoed in comments joking about the possibility of the manuscript being a hoax or simply random marks. The discussion reflects a mix of technical curiosity, historical fascination, and humor, with several users encouraging similar NLP-based investigations on other historical texts.

$30 Homebrew Automated Blinds Opener

A hobbyist has developed a $30 automated blinds opener built from salvaged components, placing emphasis on a slow, quiet operation designed to gradually let in morning light. The project utilizes a repurposed motor from a discarded water flosser and a home-built torque feedback mechanism with a magnetic encoder, ensuring the blinds stop gently at the correct position. The device features simple electronics with relays to achieve smooth, nearly silent motion, and stands out for its minimalist yet functional design—relying on low voltages and basic mechanical parts rather than complex, expensive hardware.

This DIY solution showcases the accessibility and practical value of home automation projects mostly constructed from spare parts. The creator’s approach highlights resourcefulness: opting for a straightforward, feature-driven build process that minimizes cost and complexity while offering effortless integration into a home automation network. Despite minor challenges like motor twist and alignment, the overall result is an effective gadget that provides the intended comfort boost without complicated assembly or professional expertise.

Hacker News commenters generally applaud the project’s ingenuity and the clever re-use of everyday items, sparking playful discussions about the potential and limits of affordable home automation. Some praised the project’s embrace of “slow-tech” for everyday life, while others exchanged tips on alternative motors and sensors or offered encouragement for similar budget-friendly builds. There was widespread appreciation for the balance between silence, safety, and usability, with a few voices humorously raising the bar for future gadgets—suggesting that true automation would also deliver coffee along with daylight.

France Endorses UN Open Source Principles

France’s formal endorsement of the UN Open Source Principles marks a notable political statement about prioritizing openness, transparency, and community-driven technology within national government operations. The move is seen as a potential step toward increased technological independence and a reduction in reliance on major proprietary vendors. France is the first national government to officially make such a pledge, aligning itself with international standards intended to foster reusability, secure design, inclusiveness, and open documentation at institutional scales.

However, the article highlights key contradictions between France’s public endorsement and its current procurement practices. Recent contracts within major governmental departments and leading educational institutions—such as continued adoption of Microsoft’s proprietary Office 365 suite—raise questions about the genuine depth of France’s commitment. The contrast between rhetoric and practical action is underscored, with debates centering on whether policy shifts will actually materialize, what technical hurdles must be overcome, and the trade-offs between vendor familiarity, transition costs, and open-source ideals.

Hacker News discussion is heavily skeptical of the announcement’s substance versus symbolism. Commenters widely noted the discrepancy between public commitments to open source and ongoing deals with proprietary vendors, calling into question the true intent of government strategies. There’s an undercurrent of cynicism regarding the likelihood of meaningful change, but also interest in whether increased international collaboration or transparency could result. The conversation also surfaced practical concerns—such as user retraining and infrastructure compatibility—while probing if the initiative will prompt real policy and procurement reform.
