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.

Join us to not miss out on a lot more interesting stuff.

Upgrading to Oculus 3: My Fitness Journey with FitXR | June 22 2026, 13:17

I enjoyed the Oculus 2, upgraded to Oculus 3 yesterday! Father’s day. For the last two weeks, I have only been using FitXR for about four to six ten-minute sets a day, most often in groups of three. If you, like me, have always been too lazy to go to the gym, this is a great thing. Especially convenient is that you can exercise whenever you want to break up the routine between meetings and other work during the day.

I also have a 10kg vest and 1.5kg wrist weights for this device.

Engineering Zen: A Daily Dose of Science and Creativity | June 19 2026, 03:28

Due to numerous requests, I have created a Facebook group and a Telegram channel “Engineering Zen”, where I can write about all kinds of interesting things related to science and engineering every day, and guests can write too. I’ll find it interesting if we gather at least 50 people. Shall we gather? I have a ton of interesting content, enough for a year for sure.

https://www.facebook.com/groups/4344370099148010

I will also write on Telegram if we gather at least 50 members there. The channel is called @engineersdzen.

I will be happy for the shares and likes. If we don’t gather enough people, I will drop this activity with groups and channels, which I’ve been planning to do for ten years anyway 🙂

Mind-Blowing Facts About SQLite: From Naval Beginnings to Mars | June 18 2026, 12:48

Today I learned some mind-blowing and brain-blasting facts about SQLite — the most widely used database in the world (A trillion installations. In every smartphone, browser, vehicle, A350 aircraft, even on Mars). So, it was born on the military destroyer USS Oscar Austin. It’s developed by JUST THREE people. Open source. But. You can’t just walk into this open source – it’s invitation-only and through an affidavit. The company is called Hwaci (“Hipp, Wyrick & Company”). Also involved in music (founder’s wife is a musician). Check out the website. Office — in a residential house in Charlotte. 600+ lines of tests for every line of code. 100% branch coverage and MC/DC. That is, they simulate OS crashes, power outages, I/O errors, and memory shortages. The main test suite is proprietary and closed. Imagine that, open source with paid private tests. Want access — join the consortium for $120,000 a year.

And the strangest thing — the spirit of the project is almost monastic. Instead of a Code of Conduct, they have a Code of Ethics, taken from chapter 4 of the Rule of Saint Benedict (literally 1500-year-old “tools for good deeds”). At the beginning of each source file instead of a legal notice — a blessing: “May you do good and not evil…”.

(They have not yet found a suitable version control system and wrote their own for themselves — Fossil (based on SQLite, of course). And their parser-generator Lemon is also homegrown. Just like Linus with Git.)

Innovative DIY Program for Live Transcription and Screen Capture Analysis | June 18 2026, 04:47

I made a really cool thing for myself. I launch a program, it turns on the microphone and listens. I switch to, say, a browser, comment on what I see on the screen, periodically pressing a hotkey to take a screenshot. Meanwhile, my program makes a time-stamped transcript of my comments, saves the screenshots with time stamps, then it recognizes the screenshots, extracting therefrom the spellings of various words, brands, identifiers, people’s names, so as to then transform the transcript of my speech into correct text. And all this – local models, running on my laptop, which means, absolutely free.

After I finish talking to the computer, I start processing the transcript, which takes the raw transcript and text-recognized screenshots as input and outputs a processed transcript, which now looks presentable (Gemini API is used here). One could even go a step further and automatically cut out fragments from the screenshots that were discussed, and insert them in the text exactly where they were mentioned.

Or here’s another thing I can do: just turn on a video on the speakers and the program immediately makes such a transcript for me. Google on YouTube the video “Angular HttpClient Under The Hood. Design Patterns & Source Code Overview” starting at 3:51 – I just put it on autopilot for a couple of minutes, then stopped my script.

Transforming Image Proportions with Generative AI: Smart Redesign Solutions | June 16 2026, 10:08

I published an article about how to transform images with changing proportions. Using generative AI, of course, because transforming a square into a rectangle can either result in data loss, their extrapolation, or by stretching and compressing the image itself. Here, I describe a method where smart extrapolation is performed. When processing hundreds and thousands of images, this approach is not without errors, but their number is relatively small, and it turns out to be much more advantageous to focus on manually correcting the erroneous ones than to do all the work manually right away.

This is specifically necessary during a redesign, when it turns out that the new design slightly mismatches the old one in size, for instance with banners, and the number of these banners is measured in hundreds and thousands.

Automating Banner Crop/Resize Across Breakpoints with Generative AI

AI Revolutionizing Decision-Making in Sports and Business | June 14 2026, 02:06

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?

The Secret Behind the Iconic MacOS Sound “Sosumi” | June 12 2026, 11:47

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.

Exploring Meta Oculus Quest: A Gamified Fitness Revolution | June 10 2026, 19:27

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!
