.Erik Voorhees: It’s actually good, from the Trojan horse perspective, that Bitcoin was traceable enough for traditional institutions to tolerate it. “When Bitcoin came out, everyone called it private, thought of it as private. It was referred to as anonymous in every news story. And in some ways, it is very private and very anonymous. But the truth is that it’s also extremely trackable and traceable. It is not private in reality. And the question is, should it have been from the start? And at first I thought, yes, it should have been more private. And that was a mistake in its design. However, I think if Bitcoin had been anonymous truly from the start, like a Zcash or a Monero, it would have had such antagonism from the state. I don’t know that the state could have snuffed it out, but they would have tried much harder. And I think it’s actually good, from the Trojan horse metaphor perspective, that it was traceable enough that the traditional institutions could tolerate it. They’ve never liked it, but they could at least tolerate it because there is some traceability. And that has allowed Bitcoin to grow. And I think in its shadow, that other crypto assets are actually anonymous is very healthy. The strength of cryptocurrency as a concept in society, I think, is served best when Bitcoin itself is not perfectly private, but other assets are. That is a very difficult thing, I think, for the state to combat. And that decentralization of attributes is really, really crucial. So, yeah, I’m very glad that there are other coins that are private. I want there to be more of them, and I want them to be more popular. And I think it’s okay that Bitcoin itself is not.”

The Ultimate DIY Fire Starter: Turning Waste Into Wilderness Fuel Most people clean out their dryer lint traps and toss the fuzz straight into the trash. Campers, survivalists, and backyard fire-pit enthusiasts do something much smarter: they save it to build one of the most reliable, long-lasting, and cost-effective fire starters known to man. By combining simple household waste with a bit of wax, you can create a waterproof tinder cup that burns intensely for up to 10 to 15 minutes—giving you plenty of time to catch even damp kindling. Why does this specific combination work so flawlessly? It all comes down to how different materials interact with heat and oxygen. The Lint (The Ignition): Dryer lint is made up of tiny, highly combustible microfibers (mostly cotton and wool). Because it is incredibly loose and fibrous, it holds a massive amount of trapped oxygen. This allows it to catch a spark or flame instantly. The Wax (The Fuel/Sustainer): If you light plain lint, it flashes and burns out in seconds. By adding melted wax, you introduce a dense hydrocarbon fuel source. The lint acts like a giant candle wick, absorbing the liquid wax. As it burns, the wax slows down the combustion process, extending the lifespans of the flame from mere seconds to several minutes. The Egg Carton (The Vessel): Cardboard egg cartons are made from pressed paper pulp, which is highly flammable itself. It provides a neat container to hold the fuel and serves as the structural base that burns right along with the lint and wax. Want to optimize the process? Here are a few clever hacks to get the most out of this DIY project: Use Cardboard, Not Styrofoam: Always ensure the egg carton is made of paper cardboard. Plastic or styrofoam cartons will melt into a toxic, sticky mess that releases dangerous fumes. The Crayon Trick: Don't buy expensive wax blocks. Instead, melt down old, broken crayons, leftover candle stubs, or cheap tea lights. It’s an excellent way to upcycle household waste. Add a Booster: For an even stronger burn, mix a tiny bit of sawdust, shredded paper, or a dab of petroleum jelly (Vaseline) into the lint before pouring the wax. Pre-Cut for Convenience: Don't try to rip the carton apart at the campsite. Cut the individual cups out ahead of time using a sharp knife or scissors so they are ready to pack and use instantly. While this hack is incredibly efficient, fire safety should always be the top priority: Melt Wax Safely: Never melt wax directly over an open flame or high heat, as it can catch fire easily. Always use a double boiler system (a bowl or smaller pot sitting inside a pan of boiling water) to melt it gently. Mind the Fumes: Synthetic fibers in modern clothing (like polyester or nylon) can release harsh chemical odors when burned. Try to use lint from loads of laundry that are primarily cotton or natural fibers, and always ignite these starters in well-ventilated outdoor areas. Keep Out of Reach: Because these look unique and catch fire very quickly, keep the finished fire starters stored in a cool, dry place well away from children and pets.

Marc Andreessen on how to get people to join your 3-person startup Marc says founders have two tools at their disposal to win new hires: 1) Stock options, and 2) vision. He explains: “The best entrepreneurs are really good at selling people on their company precisely because they can explain how the world is going to look in a way that is so compelling.” Marc points to Steve Jobs’s “reality distortion field” as the epitome of this: “If you get within 10 feet of Steve Jobs, whatever he says in the next 20 minutes, you’re going to walk out of there believing. He can say that the sky is purple, and you’re like yep that makes total sense . . . The best entrepreneurs all tend to have that in common and tend to be really good at that. It’s essentially sales — selling to employees. It’s an incredibly valuable skill to be able to do that. That plus stock options.” The other thing Marc has observed about hiring over the years is that right employees have to self-select into your company, even though that can be incredibly frustrating at times: “If you hired all the people you interviewed, it would turn out that 2/3rds or 3/4ths of them you probably shouldn’t have hired anyway. So what the best companies do is they provide a very stark idea of what the company is and what is it isn’t: ‘We are a company where people are expected to work 18 hour days and if you don’t like that, don’t come here’ or ‘We are a company where people expect to go home at 5pm every day and if you think that’ll be frustrating’ — whatever it is.” Marc gives the humorous example of Asana where it was a requirement that the whole company did yoga together: “If you like yoga, this is the company for you. If you don’t like yoga, don’t go there. You’re going to be asked to put your feet in positions that you’re completely uncomfortable with.” He continues: “I think the very best companies tend to be polarizing. So if in your hiring process, you’re turning people off as much as you’re turning them on because they’re deciding ‘this is clearly not the right fit for me,’ I think that’s a good thing.”

Is Traditional Software Engineering Dead? “Does this mean that traditional software engineering is dead? Absolutely not. Software engineers—even the ones who are not necessarily tuning or training AI models—these are now among the most leveraged people on earth. Sure, the guys who are training and tuning models are even more leveraged because they’re building the tool set that software engineers are using. But software engineers still have two massive advantages on you. First, they think in code, so they actually know what’s going on underneath. And all abstractions are leaky. So when you have a computer programming for you—when you have Claude Code or equivalent programming for you—it’s going to make mistakes. It’s going to have bugs. It’s going to have suboptimal architecture. So it’s not going to be quite right. And someone who understands what’s going on underneath will be able to plug the leaks as they occur. So if you want to build a well-architected application, if you want to be able to even specify a well-architected application, if you want to be able to make it run at high performance, if you want it to do its best, if you want to catch the bugs early, then you’re going to want to have a software engineering background. The traditional software engineer is going to be able to use these tools much better. And there are still many kinds of problems in software engineering that are out of scope for these AI programs today. The easiest way to think about those is problems that are outside of their data distribution. For example, if they need to do a binary sort or reverse a linked list, they’ve seen countless examples of that, so they’re extremely good at it. But when you start getting out of their domain—where you have to write very high-performance code, when you’re running on architectures that are novel or brand new, when you’re actually creating new things or solving new problems, then you still need to get in there and hand code it. At least until either there are so many of those examples that new models can be trained on them, or until these models can sufficiently reason at even higher levels of abstraction and crack it on their own… And remember: there is no demand for average. The average app—nobody wants it, at least as long as it’s not filling some niche that is filled by a superior app. The app that is better will win essentially a hundred percent of the market. Maybe there’s some small percentage that will bleed off to the second-best app because it does some little niche feature better than the main app, or it’s cheaper, or something of the sort. But generally speaking, people only want the best of anything. So the bad news is there’s no point in being number two or number three—like in the famous Glengarry Glen Ross scene where Alec Baldwin says, “First place gets a Cadillac Eldorado, second place gets a set of steak knives, and third place you’re fired.” That’s absolutely true in these winner-take-all markets. That’s the bad news: You have to be the best at something if you want to win. However, the set of things you can be best at is infinite. You can always find some niche that is perfect for you, and you can be the best at that thing. This goes back to an old tweet of mine where I said, “Become the best in the world at what you do. Keep redefining what you do until this is true.” And I think that still applies in this age of AI.”
