Unexpected Repair Success at a Premium Bike Shop | August 07 2025, 02:41

Today, I had a little odyssey trying to find a place to tune up my bike. It’s a few years old, tired, and in need of attention. I visited three shops, each told me it would take at least a week or two and would cost about 200 dollars. Everyone said there were thirty people ahead of me. Eventually, I took a chance and went to the last shop which I initially thought was too premium and expensive to consider at all: their main inventory includes triathlon Cervelo and Factor bikes with five-digit price tags. But here’s the surprise: they took the bike right away, told me to wait for a call today, and if anything serious—a decision from me would be required. In the evening, they called and told me it was all done, and the cost… just 32 dollars! I’m very glad that I did not have to overpay or wait for weeks.

This goes to show that sometimes, to achieve something, you just need to act contrary to standard patterns of behavior.

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.

Journeys and Challenges: From Washington to Mount Rainier | July 20 2025, 20:31

From Washington to Washington. Moments

From Washington to Washington. Moments. #mountrainier

I shoot three times a year, and it’s quite engaging. I wanted to say that carrying a heavy camera for 15 km (with an elevation >100 floors) while hopping on rocks in the mountains is not easy, until we met a girl there who walked the whole way barefoot.

Unexpected Costs: My Tesla Model Y Windshield Replacement Saga | July 16 2025, 17:26

Well, it hasn’t even been two months since I bought the Model Y, and I’ve already replaced the windshield. An unfortunate stone flew from under the wheels of some truck. The result — a crack that grew every few days of waiting for the repair.

Overall, it was known from the start that Tesla’s service is not as good as their cars, but so far my experience with the service has been most wonderful — except for the fact that I ended up paying $1000 out of the blue (not their fault, of course).

As soon as you get a crack, you create a claim through the app and set up a repair. The nearest available date was in two weeks from that day. The estimate came immediately through the app: $1,140. This included a new windshield ($1000 with a 50% discount) and labor — about $600. The insurance will only pay me $140, because I pay the first thousand as per the insurance terms.

The repair works like this: you arrive at the appointed time, and leave the car. The reception already knows you have arrived and why you are there. The initial estimate for completion in the app was 6 PM — that’s 10.5 hours after the appointed time. I brought two laptops, headphones, a charger, and hadn’t finished my coffee when I received a message that everything was done. It took 40 minutes.

So, the experience with their service was excellent, although of course it would have been better if there had been no need for it at all.

The Art of Lawn Striping: Creating Light and Dark Patterns with Grass | July 14 2025, 14:42

We constantly drive past fields organized into stripes or checks. I finally found the time to look into how this is done. It’s called lawn striping, and the effect is achieved by bending the blades of grass in different directions.

The direction in which the grass bends determines whether a stripe will be light or dark. When the blades lean away from you, the lawn looks lighter because the light reflects off the broad and long surface of the blade. When the blades lean towards you, the lawn appears darker because you are looking at the tips of the blades (smaller reflective surface) and you see shadows under the grass. Therefore, mowing the lawn in opposite directions (up/down, left/right, north/south, east/west, etc.) creates the greatest contrast between the stripes. Interestingly, since the “color” of the stripe depends on the direction from which you look at it, a light stripe will appear dark if viewed from the opposite side.

This fuss over grass is a very American phenomenon. I overcome my laziness to mow the lawn only when the grass has indecently overgrown (the notion of “indecently overgrown” is also something I adjust each year after receiving tsk-tsk letters from the village administration). My neighbor, however, seems to do it every few days, and I once saw him kneeling in the grass—complaining that someone had dragged something across his lot, dropping some chips in the grass and ruining its perfection. Really, the only thing missing was a pair of scissors in his hands.

The Paradox of Symmetry: Beauty, Boredom, and the Brain | July 06 2025, 23:13

Probably not just for me a contradictory perception of symmetry exists. On one hand, symmetry is perceived as a sign of harmony and stability because the brain processes and recognizes organized forms more quickly, which historically could have aided survival. Logically, it should be associated with beauty, health, and predictability, giving a sense of security.

It’s written that with one or two alcoholic drinks, symmetrical objects become even more attractive. “In a pilot study (Elena Karakashevska) involving 13 social drinkers, researchers were surprised to find that alcohol apparently enhances the brain’s response to symmetry.” The study also concluded that people look better after consuming alcohol 🙂 This reminds me of a joke about two friends, when one says, “Now we’ll go to the girls, one is alright – for me, and the other one is a bit ugly, but you drink some vodka — and she will be fine,” and when they arrive, they ring the doorbell, two women are on the doorstep, and the second says: “Oh, I can’t drink that much!”

On the other hand, excessive symmetry and monotony can cause boredom and irritation as the brain seeks stimulation and novelty. For example, imagine a symmetrical tattoo on someone. Can you picture one that you aesthetically prefer over an asymmetrical one?

Personally, I like small deviations and asymmetry, which make images lively and interesting. A certain balance of order and chaos. Pure symmetry seems very boring to me.

Started googling on the topic. “Japanese don’t like symmetry. If a vase on the table is in the middle, they will automatically move it to the edge of the table. Why? Symmetry as completion, as finitude, as repetition is uninteresting. For instance, the dishes on a Japanese table (dinnerware) will definitely have different patterns, different colors.”

Do you like symmetry?

A Costly Trip to the National Cryptologic Museum: Enigmas and Espionage | July 02 2025, 14:56

I went to the National Cryptologic Museum yesterday. Indeed, this trip will cost me $1000 because a rock hit the windshield of the new Tesla on the way. Anyway, let’s talk about the museum.

It’s very small. Located on the premises of the National Security Agency. The museum basically consists of three small rooms. One is dedicated to German Enigmas and there exhibits Alan Turing’s Bombe decryption machine, — a device as big as a kitchen in Lobnya, used for systematic decryption of messages encrypted by the Germans using “Enigma.” After the war, Churchill, for reasons of secrecy, ordered all physical traces of the program, including the Bombe machines, to be destroyed, so it’s quite a rare thing. Moreover, there’s only one working Bombe machine in the entire world, somewhere in England, and even that was barely restored. The Enigmas themselves were produced in large numbers, and the museum has two working ones; you can press the buttons and encrypt something.

In the room with computer equipment stands an old Cray, as well as a decommissioned nuclear deterrence hardware server rack taken out of service 15 years ago. It’s not very clear what’s remarkable about this – well yes, old computers, that’s all. The Cray is actually exhibited many places.

Unfortunately, there are no longer exhibits from the Star Gate project — like the blue box shown in the attached photos. The Star Gate project was used by the US government during the Cold War. Many of the psychic spies were based at Fort Meade, tasked with gathering intelligence, detecting enemy agents, and identifying vulnerabilities in the US using “remote viewing.”

Never heard of “remote viewing”? It’s the mental observation of a distant place where a person has never been, in order to gather information about an individual, an object, or specific data. As absurd as it may sound, it’s claimed that the program was quite successful and used until 1995 🙂

Specifically, this little blue machine, PSIFI, is part of that program. For example, it was used to study the impact of consciousness on random processes — like altering the behavior of random number generators through thought, collecting statistics on attempts at psychokinesis — with “hits”, “trials”, “gated hits”, “gated trials” etc., suggesting successful impacts compared to an expected random distribution, biofeedback — the lower part of the panel contains controls and inputs, apparently for electromyography and other biosignals. Overall, a good addition to the UFO research program.

Risks of High-Pressure Activities on Eye Health and Hearing | June 28 2025, 23:52

Interesting. I learned, for example, that the human retina is not really attached to the vascular tunic, but is held in place only mechanically by intraocular pressure. Because of this, those who jump from heights or engage in diving, and generally anything that increases intraocular pressure, are at risk of retinal detachment.

(By the way, about pressure, I had a slight barotrauma in my left ear today during airplane landing: after landing there was a lingering feeling of stuffiness and muffled sounds, and while in the air it even hurt a bit. That is, some traces of sensation remained several hours later, but probably, by tomorrow morning I will recover fully).
