Navigating Online Chaos: Reflections from a Russian-Language Group | July 10 2026, 00:08

I’m writing to a Russian-speaking group every day (essentially posting the same content as in my Engineering Zen group, but slightly less often and sometimes more concisely). The audience there is 100× larger, and to put it mildly, more diverse. The comments are very typical for Russian-speaking groups and resemble this story from the net:

“…An ad appeared in one chat: ‘Selling shoes, red, size 41. Worn once. 2500 R’…”

Barely 10 seconds passed and it began:

— Worn!!!!!

— red flippers, cow.

— And how much do they cost, why is it so hard to write the price right away?!

— It should be written as worn correctly.

— I am a mother who has birthed twenty children, twenty times, I have nothing to wear to school meetings. I’m already at your house, crawling through the gutter, open the vent! Give me the shoes!!

— Burn in hell! Shoes are worn!

— Worn! Respect the language.

— WORN!!!!!!

— how much do they cost?

— One should walk barefoot. Preferably through dew, all women’s diseases come from heels. And then they complain about not getting married. Fool.

— Is the size even right?

— Treating fungus later is more expensive, just wear your own beaten-up shoes.

— Ugly shoes. And you are ugly too.

— Prostitutes wear such. When can I pick them up?

— And where do you know from what prostitutes wear?

— Make way! I’ve been a fetishist for 10 years. I’ll give 300 rubles for a picture of your feet.

— Worn!!!!!!!!¡!! ¡!!!!!! ¡!!!!! ¡!!!!!!!!!! ¡! F… s, correct the mistake, I’m having a fit already!!!

— Man, why have fetishists become so poor?

— And what’s a fetishist actually, girls?

— It’s very convenient, by the way, girls. I had such a lover, when I was tired after work, I just put a hair tie on…

— WORN!!!!!!!

— Would someone just shoot her already!!

— Where did you put the hair tie?

— You surely know where.

— Well, I don’t know, your hair tie wouldn’t fit my late husband with your thin hair.

— Did your gynecologist never shout ‘Aaaauuuuu!’ down there?

— Ha ha ha. And an owl from there replied: ‘Uh-huh.’

— And bats flew all over the office.

— You’re probably glad that he finally died, aren’t you?

— Why are you being rude?!

— Let’s go to the next thread, they are selling patent leather boots, it’s boring here.

They leave, dragging along the fetishist.

Only a lonely, beautiful, and tragically grand grammar-Nazi kept standing and standing under the post, like a monument to something great and powerful…

Exploring Engineering Zen: Uncovering the Secrets of Technology and Science | July 02 2026, 21:47

I’m reminding you that I have an Engineering Zen group on Facebook and Telegram. In recent days, there have been posts about:

– Why a fridge magnet sticks only on one side, and barely on the other. It turns out, this is the same trick used to focus beams in particle accelerators. It has a name and a very unobvious “inside out”.

– A skyscraper in New York that could have been toppled by wind — and which was secretly fixed “live,” at night, while during the day offices went about business as usual. It all started with a student doubting the calculations. The story was then classified for almost 20 years.

– The fact that trolleybuses, electric cars, faxes, drones, video calls, and even humanoid robots are much older than you think. One of these robots, by the way, walked, talked about 700 words, counted on fingers, and smoked. In 1939.

– “Kelvin’s Thunderstorm” — dripping water that pumps thousands of volts and strikes with a spark. Completely without a power source. It is assembled on a kitchen table, and the energy comes not from what you might think (and it’s not a perpetual motion machine).

– A fax machine that became commercially successful before the telephone. A two-meter-tall eight-kilogram pendulum with a needle, 1860s. Guess who was the main customer.

– A simple soap film, which instantly “solves” a problem still unsolved by mathematicians in general terms. Without performing a single computation.

– Hoover Dam, inside which nearly 1000 km of pipes are hidden — otherwise, the concrete would have taken 125 years to set and would have cracked. How exactly they cooled it is a separate attraction with an ice plant right on the site.

– Those very same rusty “rusty” iron pieces sticking out in every fashionable square. They rust deliberately, and that is precisely what makes them almost eternal. Of course, they were not designed for beauty.

– Why memory cannot be erased by force of will — and why it’s so easy to inadvertently rewrite it. Also explains why so many people want to go back to the USSR.

– Benford’s Law: the first digit of a random number does not appear haphazardly — a one is at the forefront in almost a third of cases. It is used to catch fraudsters, and is even accepted as evidence in court.

– And for dessert — the world’s best mechanical calculator the size of a can, designed by a Buchenwald concentration camp prisoner. It was this work that saved his life.

Revamped Hybrismart: Engineering a Smoother E-Commerce Blog Experience | June 29 2026, 03:45

I completely redesigned and refreshed my hybrismart – an engineering blog about ecommerce. Yes, as you’ve gathered from this introduction, it’s in English. All 200+ articles have been revamped; no more style zoo, the font is easier on the eyes, illustrations are clickable, and there is now in-article navigation. It’s not perfect yet, but it’s enough to go public.

Search will be available. It’s already operational, but I temporarily hid it. Just need to finish it up.

A particular point of pride is the contextual article recommendation system. That is, next to a paragraph about drools, there will be a link to an article about drools explaining why it’s relevant in that context. On desktop, this will appear as a margin note, and on mobile, it will be an inset in the text.

The entire site is static and generated from markdown. Goodbye WordPress, you were very, very bad.

Exploring the Odd and Ingenious with Engineer’s Zen | June 25 2026, 03:38

Just a reminder that I have the Engineering Zen group on Facebook and Telegram. Recently, these topics have been covered:

– The 1956 TV remote control that had no batteries, no electronics, and not a single LED — and it worked perfectly. How? With a small hammer.

– SQLite — a database that exists in a trillion copies literally everywhere (even on Mars). It was developed by three people, originated on a military destroyer, and instead of a Code of Conduct, the developers adhere to a 1500-year-old charter.

– Eel eggs haven’t been seen for 2000 years. Aristotle brooded over this, followed by a 19-year-old Sigmund Freud, who dissected hundreds of eels, found nothing, and frustratedly left biology.

– Obelisks — a new “form of life” discovered in 2024. Not a virus, not a cell, nothing like anything else. And it lives right in your mouth. About one in ten people have it.

– Midjourney — the very company that creates images in Discord — is suddenly building a body scanner that “is better than an MRI”. You have to be scanned underwater. No, it’s not a joke.

– Light from sound. Catch a bubble in ultrasound — and it flashes. Inside, it’s 10,000 degrees for a moment. It’s assembled on a kitchen table, and physicists are still debating exactly how it emits light.

– Why memories can’t be erased by sheer willpower — and why it’s so easy to rewrite them. It also explains why so many people want to go back to the USSR.

– Why you can’t bring water on a plane — an honest engineering breakdown.

– Cicadas that have learned prime numbers to avoid getting eaten. They emerge every 13 or 17 years — and it’s a mathematically verified survival strategy.

– A Japanese mathematician who proved a great hypothesis over 500 pages in his invented language with “Hodge theatres” and “frobenoids”. Half the world believes him, the other half found a flaw. A very beautiful and very sad story.

– And for dessert — the bigger brother of a flying manhole cover in Moscow: a cast iron plate that was launched upwards at a speed of 67 km/s by a nuclear explosion in 1957 — six times faster than escape velocity.
