<p>This trend story about wired headphones is possibly a "submarine" story as Paul Graham calls it[1], like a headline that "Suits make a corporate comeback":<p><i>"The suit is back," it begins. Trend articles like this are almost always the work of PR firms. Once you know how to read them, it's straightforward to figure out who the client is. With trend stories, PR firms usually line up one or more "experts" to talk about the industry generally. In this case we get three: the NPD Group, the creative director of GQ, and a research director at Smith Barney. When you get to the end of the experts, look for the client. And bingo, there it is: The Men's Wearhouse.</i><p>[1] <a href="https://paulgraham.com/submarine.html" rel="nofollow">https://paulgraham.com/submarine.html</a></p>

<p>I have a weird long-shot idea for GPT to make a new discovery in physics: Ask it to find a mathematical relationship between some combination of the fundamental physical constants[1]. If it finds (for example) a formula that relates electron mass, Bohr radius, and speed of light to a high degree of precision, that might indicate an area of physics to explore further if those constants were thought to be independent.<p>[1] <a href="https://en.wikipedia.org/wiki/List_of_physical_constants" rel="nofollow">https://en.wikipedia.org/wiki/List_of_physical_constants</a></p>

<p>> <i>if your ISP-side modem directly outputs digital audio, the downstream channel capacity is significantly higher</i><p>But why is it higher? It's still an analog channel (the last mile from the ISP to your house), right? Doesn't it get filtered? So isn't it still subject to the Shannon-Nyquist limit?<p>Here's an ASCII drawing of which parts are digital vs analog as I understood your explanation:<p><pre><code>  Rest of world<--- digital--->Telco<---digital--->ISPmodem<---analog--->HomeModem
</code></pre>
Suppose you're saying that the link between the ISPmodem and the HomeModem is a bare unfiltered copper wire. In that case, I have a different question: Couldn't you send data at megabits per seconds over a mile long copper wire without using modems at all (using just UARTs?).<p>I hope you can clear up my confusion.</p>

<p>The Costco one uses household current (as can be seen in one of the photos that shows a cord and a plug) and the AliExpress uses USB. I doubt that USB can supply enough power to do more than a trivial amount of heating. USB 3.1 has a max of 15W, and I can't imagine that a $25 blanket is going to use the more sophisticated USB Power Delivery connections where even the cable & charger can cost more than $25.<p>While trying to find the actual power consumption of the Costco model, I found this very useful comment on the Costco site: "The power consumption is not listed anywhere - product packaging, website, or included manual. I went ahead and made the purchase and hooked it up to my battery unit once I got home. I can confirm, the blanket uses an average 99W regardless of which mode it's in. I left it in each mode for about 5 minutes. There's no difference to the touch of the blanket and there's no difference with the power consumption. In other words this blanket has one heat setting and it's not very warm."<p>So disappointing.</p>

<p>> <i>But oh what a difference it makes in the accounting! In the first case, where Autodesk sold the copy of AutoCAD to the dealer, that was the whole transaction; whatever happened to the copy of AutoCAD after the dealer paid for it has no effect on Autodesk’s books. Autodesk sells, dealer pays, end of story. But in the second case, when Autodesk sells to Spacely Sprockets, that appears on Autodesk’s ledger as a sale of AutoCAD for $1000. The instant the $1000 shows up, however, we immediately cut a check for the commission, $500, and mail it to the representative, leaving the same $500 we’d get from the dealer. Same difference, right? Not if you’re an accountant! In the first case, Autodesk made a sale for $500 and ended up, after expenses and taxes, with $125, and therefore is operating with a 25% margin (125/500). In the Spacely sale, however, the books show we sold the product for $1000, yet wound up only with the same $125. So now our margins are a mere 12.5% (125/1000).</i><p>I'd like to know how an accountant would respond to the above. Based on his two examples, it seems like accounting rules really distort the financial picture of a company.</p>

Deep into the article they admit it:<p><i>“I’ll be honest, we didn’t buy a €1 house,” he says. “We were shown something like 25 old buildings, some badly in need of repair, so at the end we opted for a three-room decent building for €10,000 and I invested more money in the renovation.”</i></p>

<p>The business model of the S1 is just wild. It mimics the PC clone industry of the 1990s.<p>From the Wikipedia page:<p><i>This product is what is referred to as a 'common mold' which means many different suppliers can produce this same model. The manufacturers are almost exclusively located in China.</i><p><i>Primarily defined by the use of a system-on-a-chip of one of the Actions brands and some common core features, S1 products vary widely in software and hardware as well as design.</i><p>I counted 62 different manufacturers listed in the Wikipedia article that apparently licensed this reference design (the core features and basic hardware), and who then made variations to the user interface or added a feature or two, and slapped their names onto it.<p>There seems to have been a whole industry of MP3 Players that were essentially identical at the core electronics level in the early 2000s, and we never realized it.</p>

<p>Given the great distances and how small the planets seem at that scale, I'm surprised that we can see any of the planets with the naked eye. Thinking about Jupiter, it's 140K km in diameter and about 629M km from Earth. That's a ratio of 1:4500. So imagine a U.S. dime that is 1.8cm in diameter placed 1.8 x 4500 = 8100 cm away. Would you be able to see a dime that it 81m or 266ft away at nighttime, assuming it slightly illuminated? We can see Jupiter, so I guess we should be able to see the illuminated dime too.</p>

<p>Just wanted to point out something that not everyone might realize:<p>Unicode is not supposed to have fonts at all. Unicode defines characters that you can then represent in various fonts. It just so happens that Unicode has many characters that happen to look like the letter "C" (as an example): © for copyright, ℂ for complex numbers (formally called Double-Struck Capital C), etc. The author uses these many variations as a fun way to make "fonts".</p>
