Pretty wild to see a drop-in replacement that's actually faster - usually that's marketing speak for "technically compatible but slower in real life." The fact that you can just pop this into existing CM4 hardware and get 2-3x performance is impressive. Finally, my commercial display can run Crysis! (Ok, maybe not, but that USB 3 upgrade is sweet).

Though I have to laugh at the "good news everyone, it's the same price!" followed immediately by "...for the 8GB version only, everything else costs more." Classic Pi Foundation pricing gymnastics. At least we're not dealing with scalpers asking $200 for a CM4 anymore.

The silkscreen specs on top is such a simple but brilliant addition. No more squinting at tiny chips trying to figure out which module is which in your parts drawer.

Fascinating piece of financial history I hadn't heard about. Imagine your government telling you to literally take scissors to your money, it's like a weird mix between arts & crafts hour and monetary policy. Though I suppose we're already halfway there with our modern central banks, just without the satisfying snip-snip sounds.

The Finnish experiment failing because people just deposited their cash in banks first is a classic example of Goodhart's Law in action. Or as I like to call it, "If you tell people you're going to cut their money in half, they'll find a way to keep it whole."

What's really interesting is Belgium's more successful approach, they went full scorched earth on 2/3 of their money supply and somehow managed to pull off an economic miracle. Makes our current inflation-fighting tools look rather tame in comparison. "Sorry, best we can do is nudge interest rates up a quarter point at a time.

Exploring the TPC-DS dataset with Trilogy feels like the perfect mix of SQL nostalgia and modern semantics. Bonus: it’s a great way to flex those data modeling muscles without a gym membership.

Microarchitectural weird machines: where your CPU's quirks are both the hackers' playground and the defenders' nightmare. Who knew speculative execution could be this creative?

Finally, a universal protocol to tame the AI-data tango. MCP is like the USB-C of context—one connection to rule them all, and hopefully fewer 'file not found' moments for our models.

Finding the perfect metric to measure 'value' in a sea of Gaussian aspirations, Pareto anomalies, and managerial whims. Maybe the best solution is simpler—just hire a team of Dostoevsky enthusiasts to measure everyone's existential worth.

How long until ticket platforms stop getting pwned by bots? What’s the real fix here—better tech, or just more gatekeeping?

I love the idea, but I feel the implementation could have been more streamlined!

I absolutely love what you guys have done – it’s truly incredible!

Fantastic work! I absolutely love all the documentation.

Exactly because without charts and diagrams, how else would we decode the mysteries of the Conjoined Triangle of Success

Thanks for your interest in our app! I wanted to let you know that the app itself is free, and all users have access to every course. However, free users are limited to just two lessons per day and won’t have access to stories or book summaries.

The paid version (and the trial period) unlocks the full experience with all the features, including unlimited lessons, quizzes, stories, book summaries, and more.

Thank you for taking the time to provide such thoughtful and detailed feedback, it’s greatly appreciated! You're absolutely right about the importance of transparency, and we’ll prioritize making our courses visible on the site. This is essential for potential users to determine if what we offer aligns with their learning goals, so we’ll address this as a matter of urgency.

To address your concerns about AI-generated content: while it’s true that we use AI as part of our process, the content is always edited and fact-checked by humans. If any information cannot be substantiated, it’s either revised or completely replaced with factually accurate data. We fully understand the risks of AI hallucination and have built robust measures to mitigate them. In fact, in internal testing, we’ve found our fact-checking process results in content that’s often more accurate than traditionally written material. We’re even considering sharing our findings to back this claim.

Here’s a list of the courses we currently offer: Philosophy, Psychology, Science and Technology, Health and Wellness, Leadership, Business, Productivity, Economics, Critical Thinking and Logic, Decision Science, Storytelling & Narrative, Self-Help, and History's Great Ideas.

As for the lack of visuals, this decision was intentional. Our research supports the idea that reading-focused content promotes deeper understanding and retention for many learners. While visuals can aid understanding, they can also distract, particularly for individuals with ADHD (like myself). For instance, in a small test we conducted, participants who engaged with text-only content retained the material better after a week compared to those who used content with visuals. That said, we’re not entirely without visuals—where necessary (e.g., diagrams for complex ideas), we’ll include them to ensure clarity.

We’ve also kept our content short and concise, designed to be consumed in around four minutes per lesson, which research shows is an optimal length for retaining information. We leverage storytelling to engage readers and stimulate their imagination, helping them connect with the material on a deeper level. As someone who has long loved books, I know the unique power of using imagination to build and explore ideas.

I hope this provides clarity and addresses your concerns. Thank you again for your input—it helps us grow and improve!

Hello Hacker News!

I’m excited to share Odyssey Scholar, an app we’ve been working tirelessly on that reimagines how lifelong learners explore complex topics. Inspired by platforms like Duolingo, Odyssey Scholar delivers structured, bite-sized courses designed to fit into your busy day. Whether it’s leadership, philosophy, business, or psychology, we aim to make understanding challenging concepts feel approachable and rewarding.

Free and Premium Access: Start learning for free with limited daily lessons or unlock unlimited access for $14.99/month or $89.99/year. Why we built this We’re lifelong learners too, and we noticed a gap: while there are many resources for casual reading, finding comprehensive, structured learning on complex topics that’s easy to consume in small doses was rare.
