🚀 Discover this insightful post from Hacker News 📖 📂 Category: 📌 Key idea: My tutorial and take on C++20 coroutines Over the last 25 years, I’ve written a lot of event-driven code in C++. A typical example of event-driven code is registering a callback that gets invoked every time a socket has data to be read. Once you have read an entire message, possibly after many invocations, you parse the message and invoke another callback from a higher layer of abstraction, and so forth. This kind of code is painful to write because you have to break your code…

Define geometric shapes, apply boolean operations, and visualize your designs in real-time with export capabilities. Important Note: This project is almost entirely vibe-coded and likely contains loads of bugs. Use at your own risk! I found learning traditional CAD software incredibly frustrating. Despite having experience with Blender, those skills didn't translate well to modern CAD solutions like Fusion 360, SolidWorks, or FreeCAD. I knew exactly what primitive solids I needed to…
🚀 Explore this awesome post from Hacker News 📖 📂 Category: 📌 Main takeaway: There are some contemporary piracy services that run ads—for marketing and, well, advertising purposes. This ranges from PPC to social media campaigns. I opted not to, mostly because I didn't think I could do it tastefully, and because I'd probably attract users who wouldn't be great customers. Instead, my marketing relied entirely on word-of-mouth—which meant building tremendous trust with my users, plus a single growth hack that I'll describe later on this page. This is all fairly standard startup knowledge—I've worked with more than a handful…

Others you really need to try. You only think you understand how a bicycle works, until you learn to ride one. There are big ideas in computing that are easy to get your head around. The AWS S3 API. It’s the most important storage technology of the last 20 years, and it’s like boiling water. Other technologies, you need to get your feet on the pedals first.…
✨ Explore this trending post from Hacker News 📖 📂 Category: ✅ Main takeaway: These are my opinions and are ruminations on what might be happening as more and more developers use LLMs and Frameworks to build on the web.In October last year I wrote “will developers care about frameworks in the future?” predicting that LLMs would abstract away framework choice. I was wrong—or at least, wrong about the timeline.The reality is more interesting and more permanent: React isn’t competing with other frameworks anymore. React has become the platform. And if you’re building a new framework, library or browser feature…
💥 Explore this must-read post from Hacker News 📖 📂 Category: 📌 Main takeaway: This is part one of a series of blog posts on temporaries, copies, return value optimization, and passing by value vs. reference. A good place to start, and the point of this first article, is how a prvalue isn’t necessarily a temporary. If you’re entirely new to value categories (lvalues, rvalues etc.), you might want to read lvalues, rvalues, glvalues, prvalues, xvalues, help! first. lvalues vs rvalues An lvalue is an expression that can not be moved from. An rvalue is an expression that can be…

After more than 200 years of sharing a unique blend of weather, wit and wisdom, we’ve made the very difficult decision to write the final chapter of this historical publication. The 2026 Farmers’ Almanac will be our last edition. Many of you grew up hearing your parents or grandparents quote from the Almanac, always having a copy nearby. Maybe you have planted by our Moon phases,…
🔥 Explore this insightful post from Hacker News 📖 📂 Category: 💡 Key idea: Filip Pizlo recently released a (solo!) project called Fil-C that adds a memory-safety instrumentation pass to clang (for spatial safety -- out-of-bounds accesses), along with a runtime support library and a concurrent GC (for temporal safety -- use after free). It is, by the standards of such tools, highly compatible with existing code -- so much so that building a full linux distro userspace seems likely within reach with only modest patching effort. The stated performance overheads (measured by Dan Bernstein at "about 1-4x cycles") are…
✨ Discover this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: Reactivating a gene that supports memory A second study, published in the Brain Research Bulletin and led by Jarome with doctoral student Shannon Kincaid, focused on IGF2, a growth-factor gene that supports memory formation. As the brain ages, IGF2 activity drops as the gene becomes chemically silenced in the hippocampus. “IGF2 is one of a small number of genes in our DNA that’s imprinted, which means it’s expressed from only one parental copy,” Jarome said. “When that single copy starts to shut down with age, you lose its…
