If you type “fifth president of Russia”, “sixth…”, “seventh…” in Yandex, Putin comes up until the hundred first. The hundredth, too, brings up only Putin. But the hundred first – it switches to Yeltsin. And the hundred second and beyond – back to Putin again.
I sure knew how to take photos once 😉
Today’s Yuki
It’s amazing that the core of curling is based on a physical anomaly that scientists have been unable to explain for 100 years. According to physics, if you spin, say, a regular glass and push it forward, friction should make it roll in the opposite direction of the spin. But the 20 kg granite curling stone defies these rules throughout its entire existence — it curves in the same direction it rotates. Either the stone leaves microscopic scratches on the ice, upon which its rear part then “jumps,” or the ice clings to it like teeth on a comb – there are many hypotheses, but clarity is nil.
There’s an interesting story in curling called “Broomgate.” In 2015, brooms with such aggressive directional fabric were released that sweepers could literally “steer” the stone like a joystick. Chaos ensued, and players from top teams (!) agreed not to use this then-legal hack out of gentlemanly honor. The federation tested 50 brooms and officially banned these “technological doping” tools. In 2024–25, “Broomgate 2.0” erupted. The controversy was not over the bristles, but the stiffness of the foam under the pad. Right during the Grand Slam of Curling (2025), top teams rebelled and signed a collective agreement to abandon these innovations mid-season. From June 2025, stiffer foams were banned — models like the BalancePlus Firm 2.0 were specifically targeted.

Today, I pondered how AI is changing age-old, even centuries-old concepts about how people should make decisions in various situations, especially in sports and probably in business. It’s far more interesting than just automation. It’s more about fixing bugs in how people have long considered something to be correct and true.
For example, in the game of “Go,” it was believed for decades that invading the corner (3-3 point) was crude and premature. AI then proved otherwise: early capture of the corner is efficient, and chasing after “beautiful” shapes loses to pragmatic control over the center. Or consider the famous 37th move by AlphaGo in the match against Lee Sedol, which was very strange: people did not play that move because they thought it was “playing into empty space.” It was first taken for an AI mistake, but then recognized as brilliant (there are plenty of analyses on YT). In esports, OpenAI Five demonstrated that aggressive early buyback of fallen heroes in “Dota,” which people considered a waste of gold, works.
Pure mathematics almost erased the mid-range shot from the NBA: it has an accuracy of about 40-42% and yields ~0.8 points per attempt, while a three-point shot with even 35% accuracy brings 1.05 points per attempt, and clubs have restructured for pure profit. Well, this is not AI, but mathematics and statistics. The under-basket shot (lay-up/dunk) turned out to be statistically the most effective.
In soccer, there’s the xG – expected goals metric; AI debunked shots from 35 meters and from outside the penalty area as ineffective (chance of scoring ~5% and 20% respectively) and ultimately teams patiently bring the ball into the penalty area, where the xG of the shot increases to 15-40%. It turns out, DeepMind had a project with Liverpool, a system advising coaches on corners – TacticAI. Expert assessors in 90% of cases preferred TacticAI’s recommendations over the tactical setups used in practice.
So, interestingly, if this continues, will a team or athlete using more powerful AI have an advantage due to more successful methods than a team that does not have such knowledge? Will AI game methods be so complex that they can’t be “stolen” to another team through outside observation – just like in the case with Go?
I find it astonishing that an unknown to me Pyotr Boborykin wrote heaps in the 19th century, introduced words like “intelligentsia” and “nonsense-maker” into the language. Considered the most prolific writer of the 19th century. Almost no one knows him besides a few philologists. And yet, the guy was a star in his time.
Boborykin was deeply concerned that he would remain in the history of literature as a “secondary” author, so he wrote furiously. He authored about 20 large novels and countless smaller works. 12 volumes, 350 pages each. Essentially, he was the Darya Dontsova of his era. He has a novel “Vasiliy Terkin” which you might have heard of, but not his; you’re likely thinking of the poem by Tvardovsky by the same name, who knew nothing about the novel at all, these were different Terkins.
For instance, finding the novel “Doctor Tsybulka” online is very challenging; there’s only one PDF in the form of a reprint with pre-revolutionary orthography.
Holy cow, it turns out there are pills to stop dogs from eating poop. They actually work. They make other dogs’ poop taste bad for dogs, plus the pills pretend to be and really are exactly what those dogs appreciate about poop
Yuki is very surprised by other dogs
Did you know that the MacOS notification sound had a name, and it was Sosumi? It was used from 1991 to 2020, then replaced by Sonumi. It has an author. It’s Jim Reeks — an Apple sound designer, and there’s a secret that wasn’t disclosed until 10 years after he left the company.
So, there was Beatles’ Apple Corps. The logo — also an apple. They had a lawsuit with Apple Inc. => Apple Inc. could use the name, but with no right to enter the music industry. When it came to creating OS sounds, lawyers got tense: Reeks, no names like “Chime” or anything, no melodies in the sounds. As a result, in OS appeared sounds like Frog, Funk, Glass, Hero.
Reeks worked long on the boot sound and created a C major chord 🙂 He writes that while creating the C major chord he was inspired by The Beatles’ song “A Day in the Life.” (I don’t know why I’m laughing here). He then jokingly suggested the name “Let it Beep” in the style of The Beatles song. It didn’t fly. Someone said it would lead to a lawsuit. Reeks: “So sue me”! He claims he sold it to the management as a “Japanese word, having nothing to do with music.”
In macOS Big Sur, the sound is now different — Sonumi. The sound file itself in /System/Library/Sounds/ is still called Sosumi.aiff.
If you ever need someone to laugh at, take a look: I saved 500 bucks today. I spent a month or maybe more thinking my car’s AC was dead. Went to a service station, got a quote. The stinginess killed me to repair it on the same day; I thought the car is old, I’ll find some garage service, refilling the AC with refrigerant isn’t critical.
Turns out, all this time I’ve been driving with the A/C turned off. The funny thing is I didn’t realize it in the car but while walking the dog.
I finally got to the Meta Oculus Quest and it’s really something! FitXR (that’s a fitness game) is particularly sweaty. Objects of various shapes fly at you to the beat of the music and you have to punch them with different movements, using hands, legs, and torso; the pace is high, almost no time to think, and after 10 minutes, you’re totally worn out. That’s the kind of gaming I like!
