The Art of Illusion in Pricing: Dishwasher Capsules and Subscription Models | August 09 2025, 13:06

An interesting marketing tactic: three different types of dishwasher capsules are sold at the same price: good Complete, premium, and premium plus. Identical packaging, identical prices, but of course, a different number of capsules. For example, platinum has 59 capsules, while the plus version has 47. It seems such odd numbers hardly register in the buyer’s mind, but not every buyer fundamentally thinks about whether it’s important for them to save money. However, if you compare the extreme versions, the platinum plus version is simply twice as expensive as the complete version.

Another interesting example – a subscription to LLM (Chatgpt, Gemini) for $200 a month. It would seem, what fool would pay a couple of hundred for something barely better than the basic for $20-30. But it’s a very sensible decision when you have a market of hundreds of millions of users: most of them are organizations. For an organization, $200 a month is not much different from $20 a month, both are negligible for the budget. Well, okay, even multiplying by hundreds and thousands of subscriptions, there are those who place themselves among slightly more premium clients at a small price for them.

Unlocking Smartwatches with Unique Heart Rhythms: A Missed Opportunity? | August 06 2025, 16:43

Why has no one made it so that smartwatches only unlock on the wrist of their owner, reading their unique heartbeat or other biometric data? This is in addition to having the owner’s phone nearby.

Officially, you can’t disable this in the settings of an Apple Watch — Apple intentionally made it such that when you put on the watch for the first time each day, it always requires a code, even if the iPhone is nearby. This is due to security policy: the watch may end up on someone else’s wrist, and the phone may just be nearby.

Moreover, every person has unique heart rhythm patterns, which include, for example, slight variations in the intervals between heartbeats, characteristics of the heart signal shape, and how the heart responds to different stresses. These microscopic differences create a unique picture” of heart rhythm that is difficult to fake or replicate. Watches have quite a lot of time, after being worn and before they are needed unlocked, to collect, process, and decide whether to unlock or not.

Aluminum: From Precious Metal to Everyday Marvel | August 03 2025, 01:09

The USA imports aluminum mainly from Canada because aluminum leaves Canada and arrives in the USA. And from Europe, it would be alumin𝒊um!

Also, sapphires and rubies are essentially rusty aluminum, where in the process the new material becomes much harder than the original. In interaction with oxygen, different varieties of the mineral corundum are formed, which chemically is crystalline aluminum oxide (formula Al₂O₃). And bulletproof glass is essentially transparent rusty aluminum, aluminum oxide, but with aluminum nitride.

Also, aluminum was the most valuable metal on Earth until the 20th century. When Napoleon III entertained guests, they ate with golden spoons, while he used an aluminum one. And the “cap” of our Washington Monument is made of aluminum for that very reason.

Decade Without Police Sirens: A Personal Observation in Public Safety Trends | August 02 2025, 23:48

Interestingly, I haven’t heard a single car siren in almost ten years, except from medical and fire vehicles. At least around here, it seems even the police don’t use them for their purposes. Apparently, the reason is that a police car with a siren behind is perceived as a command to stop and be ready to show your documents. But fire trucks and ambulances, it seems, always use theirs.

Many people don’t know that what we think of as an ambulance doesn’t really exist here. That is, you can call 911 and request a medical vehicle, and they will come, but it’s usually only done in truly critical situations—like a heart issue or if you’ve fallen from a staircase and can’t get up.

This service, EMS, always sends a bill. The minimum is $550, but typically more than $1000, depending on the type of vehicle sent—which depends on what was said on the phone—and how many miles it is to the hospital.

If transportation to a hospital is necessary, an insurance company, Medicare, or Medicaid initially pays for it. The patient might only need to pay the difference—for example, a co-pay or a deductible. If the person is unable to pay due to financial hardship, CNS will not send the bill to collections nor will they recover the debt.

If you call 911 and report that someone has fallen from a ladder, especially with a suspected head, neck, or back injury, the dispatcher will send a full fire & EMS response. That means, besides the medics, this big red fire truck shows up. It arrives not because there’s a fire, but because it is staffed with EMTs (Emergency Medical Technicians) who can begin assistance even before the ambulance arrives. Additionally, fire stations in the area are positioned such that the nearest fire truck can get there faster than a free ambulance.

In various incidents, if you can get to the hospital on your own, experience shows that it’s often necessary to go if you want results. This is not free either. Every such visit costs me $200 (insurance pays ten times more), but as it turned out later, it was always worth it. You just need to know where to go, and choose large facilities where the queues are shorter.

Exploring Unusual Time Signatures: From Prokofiev to Pink Floyd | July 28 2025, 05:32

A small concert at a Catholic university. Prokofiev’s 7th sonata features a tricky musical meter — 7/8. It’s interesting, but it seems I’ve never heard or known anything else in this meter. Early 20th-century composers were quite the innovators. Oh, I remember now. The closest to 7/8 was in Pink Floyd’s “Money” with their 7/4.

Faces of Language: Understanding the Human and Animal “Face” Across Cultures | July 25 2025, 16:35

I read about a fly on my windowsill, it’s a predatory critter, and its face is described on Wikipedia. Just like that, face. It got me thinking, is the word “face” applicable to animals other than humans (let’s skip the discussion of whether the term animal applies to humans). On the same Wikipedia, but on the face page, the face is only human. Yet, it is written that in professional terminology (veterinary, ornithology, entomology) it is quite appropriate to speak of the “facial part of the head” of an animal. For example, ornithologists at Cornell University use the term “face” specifically in descriptions of owls. Well, fine, we have a face, others have a snout. And birds? A snout in feathers? A beak is something else entirely.

In English too, by the way, things are not so simple. Even a cube has faces. In other European languages, the boundary between a human “face” and an animal one is more or less clearly drawn. Italians use faccia only for humans and muso for animals; faccia for a cat or dog would be inappropriate and even offensive. In French, visage usually means “human face,” and for animals, it’s gueule, museau, tête, etc. In Polish, there’s twarz for people and pysk/morda for beasts; moreover, the word morda in relation to a person is a crude insult (and in Russian too, only adding nationality to it). In Scandinavian languages (“ansigt” in Danish, “ansikte” in Swedish) “face” is also almost always human.

There’s also the word “physiognomy.” Interestingly, it only later came to denote a face. Essentially, this word means “the study of facial features to determine character.” It consists of φύσις (physis) – “nature, essence, character” and γνώμων (gnomon) – “indicator, determining.”

And then I remembered the word “unflattering.” Strange word, right? How can a conversation be unflattering? Turns out, its definition is as follows: “not based on flattery, the desire to please someone; impartial, fair.” So formally, Vitsyn could exclaim, “long live the most unflattering court in the world!” I’m not joking, for example, Saltykov-Shchedrin writes: “At the present time, in all corners of Russia, even the most backward people are beginning to recognize the vital need for a lawful and unflattering court.” “I must confess, I was very nervous, handing my brainchild over to the unflattering judgment of the editorial staff” (D. N. Mamin-Sibiriyak, “Features from the Life of Pepko,” 1894).

Actually, an interesting word. In Russian, its only decent synonyms are snout, mug, phiz, physiognomy, dial, and very memorable indecent ones.

Seattle Airport Chaos: IT Glitches and Alaska Airlines Grounded | July 21 2025, 07:07

Seattle Airport is at a standstill – some nonsense with IT systems, Alaska Airlines planes are not taking off (grounded).

UPDATE: remember the door that fell off Boeing mid-flight? It was Alaska Airlines and Boeing 737 Max, which I am currently sitting in.

Time Bending Flights: Greeting Seattle a Quintillionth of a Second Younger | July 19 2025, 05:19

It’s funny to stare at a sentence in a book that says when you fly to the other end of the USA, you become younger than everyone else by a quintillionth of a second — at the moment when you’re sitting on the plane flying to the other end of the USA.

Hello, Seattle!
