    Quizzino della domenica: Strana equazione

    784 - algebra
    La sonda marziana Curiosity ha trovato delle scritte dell'antica civiltà marziana. Una di esse, una volta decifrata, è la seguente: 5x² − 50x + 125 = 0: x = 5 e x = 8. In effetti 5 è una soluzione dell'equazione, ma 8 non lo è: 5×64 − 50× + 125 = 45. Quante dita avevano i marziani?

    (trovate un aiutino sul mio sito, alla pagina https://xmau.com/quizzini/p784.html; la risposta verrà postata lì il prossimo me https://wp.me/p6hcSh-91s

    Tamper Detection with Time-Domain Reflectometry

    For certain high-security devices, such as card readers, ATMs, and hardware security modules, normal physical security isn’t enough – they need to wipe out their sensitive data if someone starts drilling through the case. Such devices, therefore, often integrate circuit meshes into their cases and regularly monitor them for changes that could indicate damage. To improve the sensitivity and accuracy of such countermeasures, [Jan Sebastian Götte] and [Björn Scheuermann] recently designed a time-domain reflectometer to monitor meshes (pre-print paper).

    Many meshes are made from flexible circuit boards with winding traces built into the case, so cutting or drilling into the case breaks a trace. The problem is that most common ways to detect broken traces, such as by resistance or capacitance measurements, aren’t easy to implement with both high sensitivity and low error rates. Instead, this system uses time-domain reflectometry: it sends a sharp pulse into the mesh, then times the returning echoes to create a mesh fingerprint. When the circuit is damaged, it creates an additional echo, which is detected by classifier software. If enough subsequent measurements find a significant fingerprint change, it triggers a data wipe.

    The most novel aspect of this design is its affordability. An STM32G4-series microcontroller manages the timing, pulse generation, and measurement, thanks to its two fast ADCs and a high-resolution timer with sub-200 picosecond resolution. For a pulse-shaping amplifier, [Jan] and [Björn] used the high-speed amplifiers in an HDMI redriver chip, which would normally compensate for cable and connector losses. Despite its inexpensive design, the circuit was sensitive enough to detect when oscilloscope probes contacted the trace, pick up temperature changes, and even discern the tiny variations between different copies of the same mesh.

    It’s not absolutely impossible for an attacker to bypass this system, nor was it intended to be, but overcoming it would take a great deal of skill and some custom equipment, such as a non-conductive drill bit. If you’re interested in seeing such a system in the real world, check out this teardown of a payment terminal. One of the same authors also previously wrote a KiCad plugin to generate anti-tamper meshes.

    Thanks to [mark999] for the tip!

    @DavidBHimself I guess we will have to agree to disagree on this one.

    And yes, I did lose my right to vote when I moved a couple of times, even as a resident+citizen of said location. That’s how our imperfect electoral system works. 😥

    @evan I agree with @EricLawton -- "expatriate" is an imperial term. I see no confusion of terminology in his comment, quite the opposite.

    In the context of the poll, "expatriate" was used about emigrants, not immigrants, but the point stands. The clearest term, if a bit long and pedantic, might have been "citizens who are not residents".

    See this is exactly what I am talking about. Focussing a lens is a solved problem. There are multiple well tested and established solutions for this which work flawlessly, reliably and fast. No one, and I mean NO ONE needs a deep neural network to determine if an image is in focus. IT’S NOT A FUCKING PROBLEM AND IT DOES NOT NEED SOLVING, LEAST OF ALL WITH “AI”, FOR CRYING OUT LOUD!!!But of course here we go… 🥱https://m.dpreview.com/news/3810641278/camera-intelligence-caira#photography #noai

    📺 PeerTube Co-op FAQ: Building a Member-Owned Alternative to YouTube The future of video doesn’t belong to platforms. It belongs to people. We’re building a PeerTube co-op: a member-owned, democratically governed video platform based in BC. No algorithms deciding what matters. No corporate choke points. No waiting for permission. This is about taking control of the infrastructure, the governance, and the culture—and doing it together. Why a co-op? Because co-ops give people ownership, governance rights, and collective resilience. Instead of handing data and control to a platform, members pool resources, share decision-making, and shape policies together. BC has a strong legal framework for co-operatives, which makes it a natural place to explore this seriously. Why PeerTube? PeerTube is federated, open-source, and already battle-tested as a decentralized alternative to YouTube. It’s not perfect—but it provides a solid foundation for a co-op structure to build on top of. The idea is to pair federated tech with co-operative governance, so neither corporate control nor a single admin dictates the rules. Who’s behind this? Right now, this is being organized by me (@atomicpoet@atomicpoet.org) and @Crissy@tech.lgbt, along with a growing group of interested folks: creators, privacy advocates, security experts, and co-op thinkers from around the world. We’re still early—think founding conversations, not bylaws and board elections. But the energy is real. How much does it cost to join? What follows is the proposed model, not something set in stone. The final structure will be decided by the member-owners once the co-op is formed. The idea is to keep membership affordable for individuals while ensuring the co-op is financially sustainable from the start—with no ads, no data harvesting, and no outside investors. Just members pooling resources to run the platform together. Base membership: C$5.95/month Medium tier (10–100 GB/month): +C$3 → C$8.95/month Heavy tier (100 GB+): +C$10 → C$15.95/month At scale, with a typical user mix (80% base / 15% medium / 5% heavy), this works out to about C$6.90 per member per month, which comfortably covers hosting and operational costs. There’s also a one-time buy-in of C$50, which funds initial setup (domain, CDN deposits, buffer) and helps keep the early months profitable without raising dues. When spread over the first year, that’s roughly C$4.17/month in effective cost coverage. What happens if the co-op grows faster than expected? The financial and technical model is step-wise, not linear. As membership increases, transcoding nodes, storage/CDN tiers, and egress commitments scale at defined traffic thresholds. The co-op’s development will unfold in three phases, with member-owners deciding collectively when to move from one to the next. Do I need technical skills to participate? No. Technical expertise is welcome but not required. Governance, policy, communications, creative, and community-building skills are just as valuable. Infrastructure will be professionally managed, with costs shared through dues. Will the co-op run its own infrastructure or rely on third parties? The proposal uses managed hosting as a baseline, scaling as membership grows. This provides reliability early on while retaining the ability to self-host more components later. How will moderation work? Moderation scales with user base and federation breadth: Member reporting and rotating stewards handle first-line triage Paid moderation begins once activity reaches 10–15+ hours/week Budget estimates: up to C$270/month for ~100 users; part-time moderation (~C$1,755/month) for ~500 users Will the instance federate with everyone or be selective? The proposal starts with a curated allowlist of trusted instances to control load. It will also: Adopt shared blocklists as a baseline Document defederation criteria and appeals to keep the process transparent As membership grows, federation posture can be revisited by member-owners. What’s the timeline for incorporation and launch? We’re not working toward rigid dates—we’re building deliberately, in three clear phases: Phase 1: Formation and groundwork. Incorporation, drafting bylaws, establishing MVP infrastructure, and setting out the core policies (ToS, AUP, takedown). Phase 2: Growth and refinement. Expanding membership, activating the hybrid pricing model, introducing stipends, and refining federation posture. Phase 3: Maturity and expansion. Adding part-time moderation, building reserves and insurance, and exploring potential expansion into other Fediverse services. Each phase builds on the last, and decisions about when to transition between them will be made collectively by member-owners. What drives costs the most? Egress and bandwidth dominate, not storage. P2P offload reduces egress as viewer concurrency rises, but outbound data remains the biggest expense. How does the pricing hold up financially? At as few as five members, the co-op becomes cash-flow positive, and margins scale significantly with growth. 100 members → estimated monthly surplus C$587 1,000 members → estimated monthly surplus C$6,870 I’ve never been in a co-op before. Will there be guidance? Yes. The initial bylaws and governance structure will include clear documentation. New members will be onboarded through AGMs, published policies, and transparent reporting, as required under BC Co-operative Association law. Will you use open-source tools for internal communications? That will ultimately be up to the member-owners to decide collectively. For now, tools like Google Docs are being used temporarily to get everyone aligned quickly. Yes, the irony isn’t lost—it’s like holding a union meeting in Jeff Bezos’ living room. But this is just to get the ball rolling, not a long-term choice. How will governance work? We’re still defining this collectively, but the plan is to follow BC co-op regulations while ensuring member governance is meaningful, not symbolic. Expect conversations around: Founding member structure Board or steering committee setup Decision-making processes Transparency and accountability measures I’m not a PeerTube user, but I’m interested in the co-op structure. Is that relevant? Yes—very. Some participants are here primarily because they’re passionate about co-operatives, not necessarily PeerTube. That expertise will be crucial for getting the legal, organizational, and governance frameworks right. Will non-members be able to watch videos? Yes. As with most PeerTube instances, most viewing will be public, but uploading and policy decisions are reserved for member-owners. The co-op’s primary responsibility is to its members, while still providing an open and accessible platform for viewers. What will the co-op be called? The official name and branding will be chosen collectively by the founding member-owners after incorporation. How do I get involved or stay informed? The next step will be setting up an initial coordination space (on open-source infrastructure, if members choose that path) to keep everyone looped in and start shaping this together. If you want to be kept informed, reach out privately or share your email so you can be included when that happens. Isn’t this ambitious? Yes. But the response so far has been incredible. The mix of skills and motivations showing up this early—technical, organizational, privacy, cultural—is exactly what’s needed to make something real. 📝 Closing Thought This is still early days. But something’s forming—a group of people who see the cracks in the platform world and want to build something better, together. If that resonates with you, you’re welcome here. #PeerTubeCoop #PeerTube #Cooperative
