Anyone who's spent time with a cat knows they have some pretty interesting sleeping habits. If you've ever woken up to find your furry friend snoozing at the end of the bed, you might have wondered why cats sleep at your feet. While many cats choose to sleep at their human companions' feet, the reasons go beyond simple comfort.

If your car is feeling sluggish or struggling with rough idling, you might be dealing with clogged fuel injectors. Over time, fuel deposits can build up in the injectors, affecting their ability to spray fuel efficiently into the combustion chamber.

Today, we're delving into a sobering topic: recently extinct animals. Species extinction is accelerating, with many species disappearing due to habitat destruction, invasive species and climate change.

Today, we're diving into the legendary figure of Methuselah, the oldest person recorded in human history. Mentioned in the Bible as living 969 years, Methuselah is often seen as a symbol of longevity and divine mystery. But what makes him so significant in religious tradition?

Gold jewelry is a timeless accessory, but over time, it can lose its shine due to dirt, oils, and everyday wear. Whether you own solid gold jewelry or gold-plated jewelry, keeping it clean will help maintain its beauty.

New (well, newish) Mac app from John Siracusa:

Hyperspace searches for files with identical contents within one or more folders. If it finds any, it can then reclaim the disk space taken by all but one of the identical files — without removing any of the files!

You can learn more about how this is done, if you’re interested, but the short version is that Hyperspace uses a standard feature of the macOS file system: space-saving clones. The Finder does the same thing when you duplicate a file.

I love everything about this app. I love the name — it “works” in like at least three ways. I love that it’s right up Siracusa’s alley. I love that Siracusa has talked about it, at wonderful length, on ATP and expounded upon it on his blog. I love that the premise sounds a little crazy but the explanation makes all the sense in the world. I love that this small, laser-focused utility is fully and splendidly documented. I love the way it looks. It’s got a great icon. I mean of course it would, but still, let’s celebrate how fun this is.

As a kid I loved Richard Scarry’s books. As an adult I loved (and love) Chris Ware’s graphic novels. As a parent I loved reading Scarry’s books, again, with my son. So of course this essay from Ware, commemorating the 50th anniversary edition of Scarry’s Cars and Trucks and Things That Go, hit hard for me. Bet it will for you too.

Om Malik:

I have my own explanation, something my readers are familiar with, and it is the most obvious one. Just as Google is trapped in the 10-blue-link prison, which prevents it from doing something radical, Apple has its own golden handcuffs. It’s a company weighed down by its market capitalization and what stock market expects from it.

They lack the moral authority of Steve Jobs to defy the markets, streamline their product lineup, and focus the company. Instead, they do what a complex business often does: they do more. Could they have done a better job with iPadOS? Should Vision Pro receive more attention?

The answer to all those is yes. Apple has become a complex entity that can’t seem to ever have enough resources to provide the real Apple experience. What you get is “good enough.” And most of the time, I think it is enough — because what others have on the market is worse. They know how to build great hardware; it’s the software where they falter. In the case of Apple Intelligence, they have been caught short because others’ AI products, even when flawed, are significantly better than Apple’s own offerings.

Hardware inherently keeps a company honest in a way that software doesn’t. Hardware either works or it doesn’t. The only way to “upgrade” hardware is via installing newer software, or by taking the hardware apart and replacing physical components. It’s hard to think of a company, in any field, whose software is “better” than its hardware. Maybe Nintendo? But even with Nintendo, I’d say it’s more like their software is as good as their hardware. Also, an interesting thought that popped into my head reading Malik’s post just now: part of what makes Vision Pro so fascinating is that the software is better than the hardware. The hardware for immersive VR is so early-days that even the industry state-of-the-art — which is Vision Pro — stinks compared to where it’s going to be in even just five years. The 1984 Macintosh was a shitty computer with a 9-inch one-bit display, no hard drive, and an absurdly meager 128 kilobytes of RAM. But the software was amazing!

But the bigger, better point Malik makes is that “good enough” is enough to make Apple’s software seem ahead of its competition. I tried to make this point all the way back in 2007 with “Apple Needs a Nikon”, and I think the problem is worse now than it was then. No other company is even vaguely in Apple’s league. But Apple is sliding toward mediocrity on the software side. It’s very open for debate how far they’ve slipped. I, for one, would argue that they haven’t slipped far, and with an honest reckoning — especially with regard to everything related to Siri and AI — they can nip this in the bud. You might argue that they’ve slipped tremendously across the board. But what I don’t think is arguable is that their competition remains below Apple’s league. That’s what gives credence to the voices in Cupertino who are arguing that everything’s fine. Apple’s the only team in the top tier for UI design.

The best thing that could happen to Apple would be for Google to ship an Android Pixel experience that actually makes iPhone owners insanely jealous. Google is incapable of doing that through UI design. They’re incapable of catching up to Apple on hardware. But maybe on the AI front they can do it. Apple needs a rival.

Tesla’s share price has been having a hard time of it lately. The stock has lost about half its value since its all-time high back in December, and, since Musk took office alongside Donald Trump in January, dropped for 7 consecutive weeks, rebounding only ever-so-slightly last week, after Musk got the president of the United States to turn the White House lawn into a cheesy Tesla (sorry, Tesler) dealership. Tesla stock dropped another 5 percent today, on a day when the overall market was slightly up.

I bookmarked this Bryce Elder column at the Financial Times back on January 31, and now seems like a good time to link to it:

The usual explanation for when Tesla trading resembles a Pump.fun shitcoin is: “because Elon talks a lot”. Here’s JPMorgan analyst Ryan Brinkman to expand on the theme:

It’s not clear to us why Tesla shares traded as much as +5% higher in the aftermarket Wednesday, although we have some leading theories. Perhaps it was management’s statement that it had identified an achievable path to becoming worth more than the world’s five most valuable companies taken together (i.e., more than the $14.8 trillion combined market capitalizations of Apple, Microsoft, NVIDIA, Amazon, & Alphabet). Or maybe it was management’s belief that just one of its products has by itself the potential to generate “north of $10 trillion in revenue”. It may have even related to management guidance for 2026 (no financial targets were provided, but it was said to be “epic”) and for 2027 and 2028 (“ridiculously good”).

Brinkman, who has a long-standing “underweight” rating on Tesla, is beginning to sound a bit exasperated:

[T]he company’s financial performance and Bloomberg consensus for revenue, margin, earnings, and cash flow all keep coming down, but analyst price targets and the company’s share price keep going up. For instance, Tesla has missed Bloomberg consensus EBIT in 9 of the past 10 quarters by an average of -16.3%.

Consistently missing estimates is one thing. What Tesla has been doing is consistently missing lowered estimates. [...]

Tesla’s biggest asset is hyperbole. The more extreme the hyperbole, the more valuable it gets. Maybe after-hours market participants understand the dynamics better than Tesla bears, so are primed to park fundamentals and trade on vibes. Or maybe something else entirely is going on.

Sounds a lot like the other guy at the White House Auto Mall.

I’ve been commenting and expanding upon some of the commentary my piece prompted, and I have a few more coming, but it’s good to have Tsai collect a comprehensive overview.

Ray Maker, writing at DC Rainmaker:

This would not only be the first time Apple has created a non-watch heart rate sensor, but even more notably, the first time the company has enabled heart rate broadcasting over existing Bluetooth heart rate standards.

The question then becomes: Is it accurate?

Unfortunately, it turns out, that was not the question I should have started with. The real question to start with is: Is the heart rate function (accuracy aside), even usable? A lot of hours later, I have answers to both of those questions. And trust me, it’s a very mixed bag.

The answer:

It’s clear that any movement (even on a stationary bike) quickly leads to either dropouts or inaccurate heart rate. And outdoors running, it’s even worse. Ultimately, I don’t see any value in the heart rate sensor in this product, because it’s simply not good enough to be useful, even for casual use.

So maybe this feature is not soon coming to AirPods? I think there’s a good argument to be made that these are better than no heart rate monitor at all but also not nearly as good as an Apple Watch or dedicated device.

I’m a month late linking to it, but Chance Miller wrote a terrific review for 9to5Mac:

The last several releases from Beats, such as the Studio Buds Plus and Solo 4 headphones, have been powered by a custom Beats chip rather than an Apple-designed chip like what’s used in AirPods. For Beats, this has enabled better cross-platform support for Android users, but it’s also come at the cost of several popular features for Apple fans. For example, the Studio Buds Plus lack support for automatic in-ear detection, iCloud pairing, automatic device switching, personalized spatial audio, and more.

With the Powerbeats Pro 2, Beats has gone back to its roots and opted for an Apple-designed chip. The Powerbeats Pro 2 are powered by Apple’s H2 chip, the same chip used by the latest-generation AirPods Pro 2 and AirPods 4. This means you get the full suite of Apple-focused audio features.

The degree of shared engineering between Apple’s teams and Beats’s has always seemed odd to me. Sometimes it seems like Beats really is an independent subsidiary, focused on cross-platform headphones, and other times it feels like they’re making Apple products under a different brand label. The sweet spot seems to be about where they landed with these Powerbeats 2.

All of the aforementioned features and improvements make Powerbeats Pro 2 an incredibly compelling product, but Beats has one more thing: Powerbeats Pro 2 feature built-in heart rate monitoring.

Each Powerbeats Pro 2 earbud has a built-in heart rate monitor comprised of four components. First, there’s an LED sensor that emits green LED light at a rate of over 100 pulses per second. This light is emitted through the skin and hits your red blood cells. The photodiode then receives the reflected light from the red blood cells that is modulated by the red blood flow. There’s an optical lens that helps direct and separate the transmitted and received light, along with an accelerometer to ensure accuracy and consistency in data collection.

Beats adds that the Powerbeats Pro 2’s heart rate sensor technology is derived from Apple’s work on the Apple Watch.

It’s weird, but cool, that Beats has delivered in-ear heartbeat monitoring before Apple’s own AirPods have. But now it seems like a lock that this will be a feature in AirPods Pro 3, right?

What I always want in a review I read — and what I try to provide to readers through my own reviews — is a sense of whether a product is for me. Powerbeats Pro 2 aren’t for me — and I know it, because Miller’s review describes them so well. But they seem like a terrific product that a lot of people would prefer to AirPods Pro.

Sebastiaan de With, on X, linking to my “Something Is Rotten” piece last week:

Ex-MobileMe team here. This was a brutal time.

It was so bad that when he presented iCloud onstage, Steve said “I know what you’re thinking: why should I trust them? They’re the ones who gave us MobileMe!”

Michael Gartenberg (who worked at Apple in product marketing for a few years at the tail end of the Jobs era), responded (across two tweets):

When I was at Apple and Apple University was still around there was a whole course on MobileMe and how it was possible that things ended up the way they did. Fascinating to hear all the backstory.

One of the lessons of the Apple University course was much of the MobileMe debacle was directly because Jobs didn’t care about it. He was too preoccupied with the newest iPhone at the time. He didn’t even introduce the product, a lot of the stuff crossed his desk that he ignored.

Twitter-like social posts enforce brevity, but I suspect Gartenberg would agree that it wasn’t that Jobs didn’t care about MobileMe at all. It was that he didn’t think he had to care enough to devote his personal attention to it. Yes, Apple should offer web-based functionality for some online fundamentals (email, calendar, contacts...) and, more importantly, Apple should provide over-the-air Internet sync for that data between customers’ devices. And it should just work, in the way that a hard drive “just works” without Steve Jobs paying close attention to the current state of Apple’s file system team. But then it turned out MobileMe didn’t “just work”, and Jobs decided that he needed to pay laser-focused attention to starting over and building what we now know as iCloud (which is really quite good, very reliable, and I’d say long ago surpassed the “it just works” threshold). Steve Jobs’s final keynote — at WWDC 2011 — was largely focused on the announcement of iCloud.

Who’s got that role inside Apple today — someone with high standards, good taste, and clout within the company — for Siri and Apple Intelligence? Someone who is going to say We didn’t care enough about this, but now we need to, and will.

From Drexel’s YouTube channel:

But far less recognized is that Drexel made the very bold decision of committing all students to purchase a previously unreleased and untested computer from Apple. This was, of course, the Macintosh (introduced in January 1984), which was unlike any previous computer. Drexel’s commitment to the Mac was also of great benefit to Apple, helping to legitimize this brand-new platform, which helped make the Mac a successful product that continues to thrive in education 40 years later.

This entire initiative, called the Drexel Microcomputer Project, was captured in a 1-hour documentary filmed by David Jones, Dean of the Pennoni Honors College from 2008 to 2014. The film premiered at Drexel in 1985.

I was very fortunate not only to know Dave Jones (who died in 2018) but to have him as a professor for several film criticism courses (one on westerns, and another on the works of Alfred Hitchcock). I was a computer science major, not a film major, but Jones didn’t care. He was also familiar with — dare I say, a fan of — my column in The Triangle, Drexel’s student newspaper. He took me to lunch my senior year and encouraged me to pursue writing as a career. He was a great teacher: thoughtful, kind, insightful, open-minded, and deeply knowledgeable.

I saw a screening of Going National back in 2011, and sat on a panel discussion with Jones to talk about it. It’s a good documentary, and he really captured the feel of Drexel’s campus at the time. It is a very ’80s movie. It was gratifying that I got to tell him, then, that his advice to me back in 1996 had worked out pretty well.

Alissa Falcone, in a good piece looking back at (my alma mater) Drexel University’s groundbreaking deal with Apple 40 years ago to provide deeply discounted Macintoshes to all students, and integrate them throughout the campus and curriculums:

Drexel was prepared to buy IBM computers — and had equipped its computer centers with IBMs for decades — but the cost came to more than $1,000 per unit. IBM’s young competitor Apple, on the other hand, was willing to give discounts, provided the University agreed to secret negotiations and discreet showings of its newest, unreleased personal computer.

Bruce Eisenstein, PhD, Arthur J. Rowland Professor of Electrical and Computer Engineering in the College of Engineering, was the head of the Department of Electrical and Computer Engineering at the time, and had been the founding faculty adviser for the Drexel Computer Society started in 1972. He was Drexel’s choice to meet with an Apple representative to see the future Macintosh, which had never-before-seen properties like a mouse, icons on a screen and different fonts. This new Apple product was more powerful and easier to use than earlier personal computers; novices could supposedly master it in 30 minutes (without the need to memorize and type coded commands). And Apple agreed on the $1,000 price tag for a model that sold to the public for $2,495.

“I went back to the selection committee and I said, ‘Listen, you have to forget the IBM. This new computer from Apple is the one you have to get. They are going to make it available to us for a thousand dollars — that’s all inclusive.’ And the first question was ‘Is it compatible with the IBM computer?’ Well, no. Was there software for it? No. Were there any programs for it, like a word processor? Not yet. So the committee justifiably kept saying, well, what’s the name of this? What’s it like? I couldn’t tell them. I had to say you just gotta trust me on this. So they took a vote and unanimously voted to adopt the unknown computer that turned out to be the Macintosh,” Eisenstein recalled in Building Drexel: The University and Its City, 1891-2016.

Drexel chose the untested Macintosh even knowing that Apple wouldn’t announce it to the public until January 1984 and that the computers wouldn’t be ready until March, almost halfway through that momentous academic year.

I never had the pleasure of meeting Eisenstein, but I’d sure like to thank him for his prescience. By the time I got to Drexel in 1991 the Mac was infused throughout campus.
