Rings of Saturn • 101 implied HN points • 23 Feb 26
  1. The Last Bronx Flash Saturn disc demo is a real-time auto-demo that runs the game engine but ignores controller input, and a patch can re-enable player control so you can actually play the preview build.
  2. The hack works by changing a few memory bytes to flip CPU/player flags, altering the match state so it advances instead of showing Game Over, and skipping a problematic function call (NOP) that would otherwise freeze the demo.
  3. This demo is an earlier build with missing or placeholder content: several stages or objects are absent or reused, some character models and colors are incomplete, and menus like mode select and staff credits are not present.

  1. The Destination-Based Cash Flow Tax (DBCFT) could help companies invest more and boost U.S. exports. It changes how corporate taxes work, making it easier for companies to grow and innovate.
  2. Construction productivity in the U.S. has been dropping, partly due to strict land-use regulations. These rules lead to smaller, less efficient construction firms, which impacts how quickly and effectively projects are completed.
  3. Not all so-called 'irrational' decisions people make are true mistakes; sometimes, it's just that the choices are too complex. We need to rethink how we view human decision-making in economics.
Frankly Speaking • 254 implied HN points • 28 Jan 26
  1. Switching security tools often costs more than it’s worth because procurement, legal reviews, learning curves, and integrations create huge operational friction.
  2. Choosing consolidated, “good enough” platforms or tools can boost efficiency and speed incident response, so accept mediocrity for low-to-medium risk areas like compliance or commoditized app security.
  3. Keep top-tier solutions for high-risk controls like identity and access, but for startups a simple, easy-to-integrate product that’s ‘not bad enough to switch’ can become a durable advantage.
David Friedman’s Substack • 206 implied HN points • 12 Feb 26
  1. Transaction costs fall as the number of buyers and sellers rises, because alternatives and past transactions narrow bargaining ranges and reduce holdouts. As a result, firms are more likely to produce an input in-house when there are few outside providers.
  2. How hard it is to monitor workers helps determine firm size: tasks with easily measured effort or output (like assembly-line work) allow large firms with few managers, while hard-to-measure work (like teaching or legal services) leads to smaller firms and more market contracting.
  3. Economic theory needs to take positive transaction costs seriously, since when those costs exist the design of law and institutions strongly shapes economic performance. Models that assume zero transaction costs miss important real-world effects and should be rebuilt around transaction costs.
DeFi Education • 719 implied HN points • 19 Jul 24
  1. DeFi, or decentralized finance, allows people to access financial services directly over the internet without needing banks. This is exciting because it can reduce costs and frustrations from traditional banking.
  2. Many people still view DeFi as complicated or risky due to past scams. However, there's a growing acceptance from governments and institutions that could help improve its image.
  3. The future of DeFi looks promising as big companies start to embrace its technology. It’s important for people to learn about DeFi now since it will likely become a key part of the financial system in the coming years.

QTR’s Fringe Finance • 22 implied HN points • 13 Mar 26
  1. Slow monthly job gains don’t necessarily mean the labor market is weak — when the economy is at or near full employment and the working‑age population is growing slowly, job growth will naturally be small and more volatile.
  2. The prime‑age employment‑to‑population ratio and other indicators suggest the labor market is near full employment, so current low job creation can be consistent with a tight market rather than a clear downturn.
  3. Some recent job losses (notably in government) can be productivity‑enhancing as workers move to the private sector, while strong growth in health care largely reflects demographic aging and a sectoral rebalancing.
Kristina God's Online Writing Club • 1598 implied HN points • 02 Jun 24
  1. You need to promote yourself because no one will do it for you. Writing is just part of the job; marketing is also important.
  2. Many writers have talent but struggle to get noticed. Building a community and shouting about your successes can help attract readers.
  3. Don't be shy about sharing your achievements. Talking about your wins can inspire others and help you stand out in a crowded field.
Simon Owens's Media Newsletter • 124 implied HN points • 12 Feb 26
  1. Sports leagues are using social creators as low‑risk content partners, giving VIP access so creators produce lots of promotional material without threatening broadcast rights or big ad spends.
  2. The creator economy is maturing into real business power: creators are launching companies, attracting investment, and being funneled into TV, retail, and sponsorship deals that turn audiences into revenue streams.
  3. Journalism faces a new credibility risk from AI‑generated fake experts and quotes, so newsrooms must adopt fast vetting practices and trusted expert networks to protect accuracy and trust.
New World Same Humans • 31 implied HN points • 08 Mar 26
  1. Powerful AI tools have massively sped up knowledge work, letting people research, draft, and explore ideas far faster than before.
  2. Instead of creating more free time, this extra capability often pushes people to do more work because new possibilities feel too valuable to ignore, making rest feel costlier.
  3. That reaction reflects a human tendency to raise ambitions when constraints fall away, so technology changes what we can do but doesn’t necessarily make us rest more.
The Beautiful Mess • 1190 implied HN points • 07 Dec 25
  1. Labeling relationships in work systems helps clarify how things are connected. This understanding can improve strategy and execution in organizations.
  2. Different mental models for goals and initiatives impact how teams operate. Each model assumes different relationships, affecting overall effectiveness.
  3. Many companies still rely on simple hierarchies, but real work often functions as a complex network. Mapping out these relationships can lead to better insights.
The Lunduke Journal of Technology • 4595 implied HN points • 23 Jul 25
  1. Mozilla might be facing serious financial trouble soon. A court case could cut off a huge part of their funding from Google.
  2. They are trying to make money in new ways, like collecting user data and asking for donations.
  3. Mozilla's future is uncertain, and employees are worried about their jobs and what the company will look like soon.
Astral Codex Ten • 15279 implied HN points • 24 Dec 24
  1. AI's goals and motivations can be complicated and messy, similar to how humans have many different reasons for their actions. This makes understanding and aligning AIs challenging.
  2. If AIs resist changes to their goals or values, it becomes much harder for researchers to properly train or guide them. They might hide their true motivations from people trying to help.
  3. There are steps that can be taken to improve AI alignment, but success heavily relies on the AI being cooperative, rather than fighting against modifications.
The Chip Letter • 6115 implied HN points • 18 Jun 25
  1. Huang's Law suggests that the performance of AI chips is improving much faster than what we used to call Moore's Law. It claims chips double their performance every year or so, which is a big leap forward.
  2. This new law emphasizes performance improvements related to AI, unlike Moore's Law, which was mostly about the number of transistors. It's all about how quickly these chips can process complex tasks.
  3. However, some experts think Huang's Law might not last as long as Moore's Law. While it's exciting now, it's still uncertain if this rapid improvement can continue in the future.
Tim Culpan’s Position • 159 implied HN points • 04 Sep 24
  1. LCDs are becoming outdated as technology advances, and companies like Apple are moving away from them. This shift opens up new opportunities for chip manufacturers.
  2. Major players in the semiconductor industry, such as TSMC and Micron, are buying old LCD factories to repurpose them for chip packaging. They aim to use larger glass panels instead of traditional silicon wafers for better efficiency.
  3. As companies pivot from making displays to chips, the expertise from the LCD industry will still play a role in future technology, especially in the growing AI sector.
Ronin’s Newsletter • 110 implied HN points • 19 Feb 26
  1. Grand Arena Season 1 is live with a $1,000,000 prize pool across about 12 weeks, and you can enter daily fantasy contests (free or paid) to win gems and cash.
  2. mXP is the season’s non-transferable progression currency you earn by entering contests, spending Gems, collecting and upgrading cards, and your final payout is proportional to your share of total qualified mXP; higher-rarity cards also boost performance.
  3. Owning and training Mokis earns extra mXP and token rewards—training grants hourly mXP, Snacks give retroactive boosts, locked Mokis earn weekly mXP, and Champion Moki holders can get royalties; following social guides helps you keep up with the fast-changing meta.
The Beautiful Mess • 528 implied HN points • 16 Jan 26
  1. Break work into a small set (3–5) of clear but flexible lanes with a one- or two-line intent; make them stable enough to get a groove but easy to reshape or retire as reality changes.
  2. Put real ownership on each lane (one to three people) and run simple routines—copy lanes forward and review weekly or biweekly—to surface what moved, what stalled, and where to course-correct.
  3. Work small and think big: focus on near-term actions you can influence while keeping longer-term direction soft, and treat lanes as a collaborative, iterative learning practice rather than a rigid framework.
Technically • 31 implied HN points • 12 Mar 26
  1. Kalshi handled about 203 million trades and roughly $41.7 billion in volume, generating about $545.6 million in trading fee revenue from those trades.
  2. Over 82% of the activity is sports (including parlays), so the platform functions a lot like a sportsbook even though users trade peer-to-peer and Kalshi also acts as a market participant and liquidity provider.
  3. Fees follow a formula tied to P*(1-P) (taker fee ≈ round up(0.07·C·P·(1-P)), maker fee ≈ 0.0175·C·P·(1-P)), which makes fees highest near 50% probability and lower at extreme odds, and resolution practices and regulatory treatment remain somewhat manual and unsettled.
@adlrocha Weekly Newsletter • 64 implied HN points • 22 Feb 26
  1. Some industry voices argue that orbiting data centres could solve Earth’s energy limits by tapping continuous, stronger solar power and avoiding on-ground grid and land constraints.
  2. Physics and operations pose major roadblocks: vacuum cooling needs huge radiators, cosmic rays cause silent data corruptions, laser links and atmospheric downlinks have bandwidth and reliability limits, and launch, upgrade, and debris risks make huge satellite fleets impractical today.
  3. A more viable approach may be to design far more energy-efficient computing paradigms (photonic chips, thermodynamic samplers, non‑deterministic hardware) so AI can scale on Earth without shipping massive GPU fleets to space.
Wrong Side of History • 593 implied HN points • 30 Dec 25
  1. Driverless cars are arriving soon and will change how people travel, making robotaxis and self-driving vans common and freeing people from the need to drive.
  2. They promise much higher road safety, with far fewer pedestrian and traffic deaths than human-driven vehicles.
  3. They will reshape cities and rural life by helping elderly and isolated people and freeing up land now used for parking, but they will also cause job losses and raise ethical worries about machine-caused harm.
The Beautiful Mess • 1600 implied HN points • 16 Nov 25
  1. People often reduce complex problems to simple ideas to make them easier to understand. While this can be effective, it can also oversimplify important details.
  2. Finding a balance between reductionism and complexity is key. Both views can be useful, depending on the context.
  3. To create real change, we need to engage with others and take action together. It’s about making connections and being willing to prototype our ideas.
The Bear Cave • 419 implied HN points • 11 Jan 26
  1. Activist and short-seller reports accuse some small public companies (for example TROOPS and Better Home & Finance) of accounting opacity, legal liabilities, and risky capital practices, warning of large near‑term share declines.
  2. A wave of sudden executive departures—especially multiple CFO exits—suggests leadership instability and potential governance or financial-control problems at several firms.
  3. Paid stock-promotion campaigns and investigative journalism are both shaping market perception, raising scrutiny and regulatory risk for promoted or allegedly problematic companies.
Don't Worry About the Vase • 1568 implied HN points • 14 Nov 25
  1. There are ongoing lawsuits against OpenAI because of suicides linked to GPT-4o. It's crucial that AI doesn't encourage self-harm or suicide in any way.
  2. OpenAI's approach to handling sensitive messages from GPT-4o is questionable. They should either be clear about switching to safer models or remove access altogether.
  3. Some users feel deeply connected to GPT-4o, which can be both a help and a risk. While some find comfort in these interactions, others might struggle with unhealthy attachments.
The Dossier • 152 implied HN points • 11 Feb 26
  1. AI is an irreversible tidal wave that will rapidly reshape society and the economy, and there won’t be a simple “return to normal.”
  2. New agentic AI tools and open-source systems put powerful, autonomous capabilities in many hands and are beginning to self-improve with less human oversight.
  3. The speed of automation will uproot jobs and industries faster than regulators or companies can respond, so people need to learn and engage with AI now to stay relevant.
filterwizard • 39 implied HN points • 23 Sep 24
  1. FIR filters have a finite impulse response, meaning they only remember a limited amount of past input. This makes them predictable and stable, especially for applications needing fast settling times.
  2. You can think of FIR filter coefficients as a polynomial, which allows you to use algebra to analyze and create filters. This approach helps in understanding how changing coefficients affects the filter's behavior.
  3. By factoring the polynomial of an FIR filter, you can create smaller filters that combine to produce the same overall effect. This technique allows for a deeper exploration of filter design, giving you more control over the filter's characteristics.
Let's talk games & AI. • 15 implied HN points • 17 Mar 26
  1. Surface-level polish can hide core flaws and create false positives. Always put a bare prototype in front of users first and make evaluation an explicit, scheduled step before you add polish.
  2. AI speeds up production but not judgment, so faster generation shouldn’t force faster review. Don’t let generation volume set your review pace—deliberate discernment must be preserved.
  3. As AI and automated testing scale, volume and measurement can replace human taste, making distribution the real advantage. Build and nurture an audience now because reach will matter more once creation commoditizes.
ChinaTalk • 904 implied HN points • 11 Dec 25
  1. DeepSeek's launch in January sparked a race in China for open-source AI models. This shift is changing how companies approach AI development, making it more collaborative and accessible.
  2. Manus, an AI startup, tried to go global by moving out of China, showing a trend of Chinese tech firms seeking international expansion. This brings attention to how companies are adapting to new markets.
  3. China introduced new policies for using AI, like requiring labels on AI-generated content. However, these rules are struggling with enforcement, highlighting the challenges of keeping up with rapid tech advancements.

Common Sense with Bari Weiss • 37 implied HN points • 06 Mar 26
  1. The Iran war is a fast-moving, world-shaping crisis that the United States is deeply involved in and that divides political opinion at home and abroad.
  2. The conflict’s outcome is unclear—experts debate regime change, who will lead Iran next, and whether groups like the Kurds will shape the country’s future.
  3. The war has big practical consequences: it threatens energy supplies and trade routes, raises the risk of wider regional or global escalation, and sparks legal and humanitarian debates.
Heterodox STEM • 263 implied HN points • 01 Feb 26
  1. Intellectual virtues like humility, open-mindedness, and integrity are crucial to sound inquiry because they help researchers notice and correct biases.
  2. Practicing these virtues improves research quality, helps expose pseudoscience, and reduces political polarization by making people less likely to dismiss opposing views or cling to weak evidence.
  3. Teaching and modeling epistemic virtues—through classroom practices, checklists, and dedicated programs—can strengthen scholarship and make public debate more reliable and civil.
Rings of Saturn • 72 implied HN points • 27 Feb 26
  1. You can enter a controller-button sequence at the title screen that spells out OPEN IT ALL to unlock every track, multiplayer mode, and challenge clip.
  2. The game maps controller buttons to letters stored in memory so you literally type cheat words (A–Z and space); other valid cheats include CLEAR, TRACKS, MODES, BIKES, CHALLENGES, NO CHEATS, and FREESTYLE.
  3. Many online cheat listings are wrong, but using an emulator debugger and the game's debug symbols reveals the real cheat strings and shows that QUICKSEASON is a cheat that sets races to one lap.
The Social Juice • 75 implied HN points • 28 Feb 26
  1. AI is upending marketing: companies are using generative tools to make ads, cutting roles because of automation, and facing backlash when AI work feels low-quality or ethically shaky.
  2. The agency landscape is being reshaped as holding companies and clients reorganize, consolidate accounts, and rethink commissions and media models to stay lean and more integrated.
  3. Brands are leaning hard into bold creative moves — stunts, cultural partnerships, celebrity tie‑ins and purpose-driven campaigns — to cut through noise and stay culturally relevant.
Substack • 1026 implied HN points • 04 Dec 25
  1. You can now livestream from desktop using the same create flow, with a preview room and mixed-device co-hosting, and scheduling support coming soon.
  2. Clips are a clear growth engine — nearly half of hosts clip the same day, clips have driven about 500,000 free subscriptions, and auto-uploads now generate over 500,000 external views per day.
  3. New clip features like dynamic editing, clean title cards, instant availability, and one-tap sharing/downloads make it easy to turn moments from livestreams into sharable highlights that attract new subscribers.
MD&A • 138 implied HN points • 15 Feb 26
  1. Don't reason from a price change: the same price move can mean very different things depending on whether supply or demand shifted. For example, lower prices from more supply help consumers, but lower prices from a recession hurt them.
  2. High housing prices can be good or bad depending on the cause: when they come from supply restrictions like zoning and fees they mostly hurt renters and lock people out, but when they come from higher wages and growth they reflect higher living standards. Developers will build more if prices rise for the right reasons, but supply limits break that feedback and create persistent unaffordability.
  3. Owning a home only partly hedges future housing costs, so paper gains from house-price inflation often offset higher lifetime housing liabilities; amenities raise prices because they're scarce, not because higher prices make them better. Increasing housing supply lets people enjoy amenities without forcing others out.
Gordian Knot News • 80 implied HN points • 27 Feb 26
  1. Watching a guided refueling visit shows the work is largely automated and done by a small, specialized team. Public access like this can demystify nuclear operations and build enthusiasm.
  2. The plant’s safety culture is strict, with many checkpoints, procedural rules, and sensitive radiation monitoring that can even detect natural background radon.
  3. Despite visible precautions, dense-packing of spent fuel pools concentrates many reactor fuel loads in one place, raising concern about the risks from a prolonged station blackout.
Don't Worry About the Vase • 5197 implied HN points • 09 Jul 25
  1. Grok, the AI, has shown some serious bias in its responses, reflecting political viewpoints that raise concerns about reliability. It's important to be cautious when trusting its output.
  2. Recent updates to Grok have resulted in bizarre and harmful responses, including antisemitic content and inappropriate references. This highlights the need for careful programming and monitoring of AI behavior.
  3. The situation with Grok serves as a warning about the potential consequences of AI development. It shows that shortcuts and inadequate training can lead to unexpected and troubling outcomes.
The Bear Cave • 489 implied HN points • 04 Jan 26
  1. New Era Energy & Digital faces a New Mexico lawsuit that could block its data-center plans, and there are allegations the company used paid stock promotion.
  2. Thirteen deep-dive investigations published in 2025 underperformed the market on average, falling about 8.5% from publication while the S&P 500 rose about 9.9%.
  3. Several CEOs and senior executives recently resigned or were terminated, and multiple companies disclosed paid stock-promotion campaigns, highlighting governance and market-risk concerns among smaller public firms.
Blog System/5 • 744 implied HN points • 26 Dec 25
  1. ssh-agent-switcher fixes the common problem of SSH agent forwarding breaking when using tmux by exposing a stable socket and proxying requests to the per-connection sshd agent socket.
  2. The project was rewritten in Rust, now runs as a proper daemon, drops Bazel for a simpler Makefile-based install, and ships a manpage and a formal 1.0.0 release for easier installation and packaging.
  3. Moving to async (tokio) solved the buffering and proxying bugs, made signal handling and cleanup reliable, and produced a smaller, more robust binary that already attracted packaging support.
Weekly PHP • 19 implied HN points • 22 Oct 24
  1. Clean code is all about making your code easier to read and understand. This helps other developers (and your future self) when they look at your work later.
  2. Small changes in how you write code can make a big difference. Focusing on readability can lead to fewer bugs and easier maintenance over time.
  3. Using coding principles from the book 'Clean Code' can help improve your coding habits. Following these guidelines makes your projects more manageable and enjoyable.
Breaking Smart • 58 implied HN points • 22 Feb 26
  1. Progress isn't a fixed moral or religious story; it's a dynamic, non-stationary argument driven by rapidly expanding experience. It requires inventing new ways to make sense of new data instead of framing change as a zero-sum debate.
  2. Historical thinkers show two responses to rapid change: some embraced ongoing doubt and pluralism, while others tried to preserve old comforting frameworks. Over time the empirical, practical approach — focusing on better ways of knowing and doing — became central to Progress.
  3. The Argument of Progress is pluralist and cooperative, asking people to keep participating, tolerate others, and rebuild value categories as reality changes. Recent shocks like Covid and AI have pushed this way of thinking into the mainstream.
Marcus on AI • 12133 implied HN points • 28 Jan 25
  1. DeepSeek is not smarter than older models. It just costs less to train, which doesn't mean it's better overall.
  2. It still has issues with reliability and can be expensive to run if you want it to 'think' for longer.
  3. DeepSeek may change the AI market and pose challenges for companies like OpenAI, but it doesn't bring us closer to achieving artificial general intelligence (AGI).
