Something unusual just happened. Amazon is promoting my book — and subsidising the print cost. The full-colour premium edition is now <50% of its usual price. No promo on my side. Just the algorithm pushing it. Won’t last.

I can't go back to the regular YouTube UI after this 😅 Obsidian Reader now makes the transcript interactive so you can scrub, highlight, auto-scroll. It feels so nice.

@paulg Some real situation from Ukraine that you could replicate: turn of electricity for 24 hours. Take them to sleep at metro station.

Explained to my sons that war is actually horrible, but boys think it's exciting because they imagine it's like their lion-cubs-wrestling version of fighting writ large, and no one wants to give them nightmares by telling them what it's really like.

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.”

@levelsio is that the reason why cashiers often grumpy? they just poisoned with receipts?

@levelsio@levelsio·
One of the most overlooked sources of toxic hormone disruptors are receipts: > Thermal receipt paper is often coated with Bisphenol-A (BPA) or its substitute, Bisphenol-S (BPS), which are endocrine-disrupting chemicals that can absorb into the skin. > Studies suggest that even brief 10-second exposure can exceed safe thresholds, potentially harming reproductive, metabolic, and hormonal health The thermal paper literally leaks BPA into your skin in seconds and then disrupts your hormones heavily: > BPA (Bisphenol A) is a potent endocrine disruptor that primarily mimics or blocks estrogen (estradiol), but also interferes with androgen, thyroid, and metabolic hormones > BPA instantly binds to estrogen receptors (ERa, ERb, GPER) and androgen receptors, causing reproductive dysfunction, decreased testosterone, altered FSH/LH levels, and metabolic issues like insulin resistance This one was wild for me and took me awhile to fact check, because we handle so many receipts in a single day and I couldn't believe it'd be this bad These days I try ask for a digital receipt or take a quick pic of the receipt without touching it a lot

@levelsio really “Receipt paper (BPA)” … like enough to matter ?

🇨🇳 I found the rentable powerbanks in China One scan to pay with Alipay and then you take the battery and you return it later This would never work in US or Europe because people would just steal the powerbanks
Migue@MigueMorkin

@levelsio (Possibly already many people told you about this) Just in case, I strongly suggest just using Meituan network of chargers. You can pay them using your WeChat or Alipay account, and charge you by minutes consumed. Super convenient.
