The Hidden Golden Ratio in Bicycle Geometry

The Hidden Golden Ratio in Bicycle Geometry A Surprising Discovery in Frame Proportions While designing a minimalist aluminum bicycle frame, I stumbled upon something remarkable that appears to have gone unnoticed in cycling literature: the relationship between front-center and chainstay length across most mountain bike frames approximates the golden ratio (φ ≈ 1.618). The front-center is the horizontal distance from the front wheel axle to the bottom bracket, while the chainstay length runs from the bottom bracket to the rear wheel axle. When you divide the front-center by the chainstay length across various bicycle types, a consistent pattern emerges. Road bikes typically show front-centers of 680-720mm with chainstays of 410-420mm, yielding ratios between 1.62 and 1.71. Mountain bikes display front-centers of 700-750mm and chainstays of 430-450mm, giving ratios from 1.59 to 1.67. Gravel bikes fall into similar territory with front-centers of 690-730mm and chainstays of 420-435...

Rethinking Luggage Privacy in the Age of Oversharing

Image
In an era where we casually share vacation selfies, location data, and even our DNA and heartbeat with apps and platforms, one thing we continue to fiercely protect is… our suitcase. What's in a suitcase? - Images: Grok The average piece of checked or carry-on luggage contains nothing revolutionary: a few outfits, some toiletries, maybe a laptop or paperback novel. Yet, we insist on opaque bags, as if the contents were deeply private. It’s a habit we’ve inherited, not one we’ve ever really thought about. And it may be time to ask: why? Privacy Theater: A Game We Keep Playing This instinct to hide our belongings is less about protecting personal information and more about repeating a social ritual. We cover our bags not because we need to, but because that's what everyone does. It’s behavior on autopilot. But here’s the irony, we’ve already surrendered most of our truly private data . We have already surrendered everything which is important: Our phones track us, our...

Accidental Privacy: Dell’s Linux Assistant Fails to Phone Home

Image
Many users choose Linux for reasons of control, transparency, and privacy. So it's worth paying attention when software quietly undermines those principles. Recently, I discovered that Dell’s Linux Assistant for Ubuntu contains built-in telemetry code,  code intended to log and send metrics about user behavior. The kicker? It fails silently due to a minor Python bug. The result is what you might call an accidental privacy enhancement . Hidden Telemetry Dell’s Linux Assistant is supposed to make life easier for Ubuntu users running Dell hardware. It manages drivers, firmware, and support tools. Nowhere in the user interface or documentation does it mention telemetry. Yet, digging into its code  or, in my case, encountering a stack trace reveals that it tries to log an event when the user closes the app: QueueMessageClient(...).LogLogMetricEvent("FRONTEND", "Dell Linux Assistant closes") This function uses a scheduler to send telemetry data: usage logs,...

What If the Time Spent *Was* the Point?

* Reclaiming Meaning in the Age of Instant Everything* I’m from early Generation X, raised with a particular dream: that AI and robotics would *finally* liberate humanity from drudgery. Not to make us lazier, but to give us the freedom to pursue *nobler* things: philosophy, art, reflection, even idleness with purpose. That dream still flickers. But lately, it’s flickering in the shadow of something darker: not a future of liberation, but one of numbing convenience, where meaning is bypassed in the rush for efficiency, and the effort that once made life feel rich is treated like a bug in the system. A recent article summed up this fear powerfully. It argued that we're systematically destroying the biological reward system that makes effort feel worthwhile. Not by accident, but *on purpose*. In our quest to eliminate friction from life, we’ve also eliminated the very struggle our brains are wired to reward. The satisfaction of cooking, creating, learning, and slowly improving ourselv...

AI Alignment and the Human Fabric of Deceit

Image
As "artificial intelligence" grows in power and generality, the question of how to align these systems with human values, or at the very least, with human intentions, becomes existentially important.  Most of the contemporary alignment conversation focuses on optimization, feedback, and safety: how to guide a model’s behavior using techniques like reinforcement learning from human feedback (RLHF), red-teaming, or reward modeling. These are all valid concerns. But what if the deeper issue lies not in the process, but in the substrate? What if the problem isn’t just that our data is noisy, biased, or incomplete, but that deception itself is woven into the very structure of human thought? This isn't a novel claim in philosophy or literature. From Plato’s cave to Freud’s defense mechanisms, from Nietzsche’s “will to illusion” to postmodern critiques of ideology, thinkers have long suspected that much of what we call “knowledge” or “tru...

The Flame That Never Burned: Technology, Intelligence, and the Melancholy of the Deep

Image
What if the stars could be dreamed of, but never reached? What if the tools of transformation lay forever out of grasp? Image generated by LLM We humans often take for granted the raw material of our progress: fire. From the first flickering spark in a cave to the controlled infernos of blast furnaces and rocket engines, fire has been our great transformer, a force that allowed us to rework the world at every scale. At its core, technology is the transformation of matter, and fire is the energy that enabled it. But what if intelligence had arisen in a place where fire could never exist? The Fire Barrier Imagine a species of Homo sapiens-level intelligence evolving not on land, but in the crushing depths of an alien ocean. Or even Earth’s own ocean, had history flowed differently. Cephalopod-like minds, self-aware and curious, living in a world of currents, pressure, bioluminescence, and utter absence of flame. Fire cannot burn underwater. There are no sparks, no embers, no forges....

Brazil’s PIX System Exposed to Legal Risk for Withholding Its Source Code

Image
Image:  pexels.com As Brazil undergoes a rapid digital transformation of its public services, the debate around transparency, technological sovereignty, and the role of open-source software in public administration becomes more urgent than ever. Yet, one critical point, largely absent from public discussion, raises a serious legal and ethical concern: the development and distribution of digital systems by the Brazilian state, with PIX as a prime example. What Does the Law Say? In 2021, Brazil enacted Law No. 14.063, which governs the digitalization of public services. Its Article 16 is clear: “Information and communication systems developed exclusively by the public administration shall be governed by open-source licenses, allowing their unrestricted use, copying, modification, and distribution by all public agencies and entities.” In short, software developed solely by the public sector,  funded with taxpayer money and intended to serve the public interest, must be ma...
