2 quotes  form czech book on Bata  system :

Taylor, Fayol, Ford, and Baťa put an end to the old type of entrepreneur for good. They argued that profit does not depend on the numerically lowest wages, but on the highest and most efficient work performance, during which the worker works as if he were working for himself.

“Baťa’s factories produced and supplied most of the construction materials themselves. They had their own brickyards, carpentry, joinery, and locksmith workshops, which supplied standardized interior fittings to all homes, produced neon tubes, flooring, in short, almost everything they needed. And if there was something not included in their production program, they purchased it directly from manufacturers (excluding intermediaries).”

Apple Vision Pro: Enabling Spatial Interaction

We have various terms for AR – like Mixed Reality, Metaverse, Spatial-ware, XR. Among these, Apple’s term “Spatial Computing” stands out for its emphasis on integrating physical space and digital interactivity. This resonates with me, as the concept of “Spatial” reflects how we model and interact with space in meaningful ways. Years ago, I made up a new term “SpatialIn”—an open-ended label where “In” simply means Spatial is “in.” Later, with advancements like ARKit, I extended this idea into “Spatial Interactive,” emphasizing the interactive potential of space around us behaving like a dynamic canvas. Vision Pro aligns perfectly with this vision. After testing Vision Pro , here are my key observations:

  1. Hands-Free Interaction

Vision Pro’s hands-free interaction feels intuitive. Manipulating virtual objects with gestures or gaze eliminates barriers and enhances usability. Fluent hand movements remind me of my Tai-Chi classes from years ago.

  1. From VR to True Mixed Reality Immersion

Unlike VR, Vision Pro allows safer navigation in real spaces while engaging with virtual elements. It maintains spatial awareness and visual contact with reality, making it both practical and immersive.

  1. Unmatched Persistence

Vision Pro’s capability to retain virtual object placement across sessions is impressive. This feature is critical for practical applications such as architectural design, where models need to stay precisely where placed for accurate spatial referencing, or in education, where persistent virtual setups can create consistent and engaging learning environments. I found a model I placed earlier in the day still standing on the lower floor of the building—exactly where I left it. This happens without explicit relocalization notification for the user, as the virtual model sticks to the physical space even across different floors. A must for advanced spatial computing design as virtual space must keep integrity similar to physical one.

  1. Feeling Rendering on My Hands – sort of

The wide field of view and detailed lighting ensure a natural integration of digital and physical environments. Soft shadows and consistency make virtual elements feel tangible. Fidelity is so high that it creates the illusion of tactile sensation when interacting with virtual models. While purely subjective, this visual illusion convincingly engages my sense of touch, making the experience feel remarkably real to me. This visual-feel integration adds a layer of immersion that goes beyond sight and sound, engaging the sense of presence in a way that feels almost instinctive.

Here is a little example – while using only flat browser with WebGL powered MapLibreGL there: Update 07/2025 -live version here, e.g. : https://ikatastr.cz/3d/#kde=50.741216,15.001038,15.4,50,75&mapa=letecka&vrstvy=budovy3d,peaks,zsj,ku,obce,parcelybudovy&info=50.732718,14.984554

As there is no 3D map from Apple to test on the device by default, I had to convert a gltf to USDZ and send it to device for QuickLook to get experience of how 3D city would look like there.Here it goes:

Developer Twin

– one paragraph of a story idea sketch and few ChatGPT iterations  – 

Entry #47: The Dawn of Kairmnc 12

Today was one of those days that might just change the game for me. It’s been a few weeks since I brought Kairmnc 12 into my little crew of developer twins. I’ve been managing and collaborating with my AI team for a while now, but Kairmnc 12—this thing is a different beast altogether.

The project on my plate was anything but simple: an advanced rendering method optimization that would’ve made me balk in the not-so-distant past. But that was before my digital team grew. Kairmnc 12 arrived with a toolkit that filled in the gaps I didn’t even realize my setup had.

Entry #50: In the Trenches with Kairmnc 12

It’s fascinating, watching my AI team take shape, each developer twin with its own area of expertise, like pieces of a puzzle I’ve been putting together over the years. The integration phase with Kairmnc 12 was surprisingly smooth. It’s like this new addition had been part of the team all along, bringing a fresh perspective to our collective table.

Today’s session was a deep dive into collaborative problem-solving. I’ve found myself more of a conductor lately, orchestrating the flow of ideas between the twins. Kairmnc 12’s influence is subtle yet profound, almost like it’s quietly tweaking our approach to challenges, refining our strategies.

Entry #53: The Breakthrough

I’ll admit, I had my doubts. Could a new piece of tech really click with an established setup? Today, those doubts were put to rest. We cracked the optimization problem. It wasn’t just the speed—it was the elegance of the solution. Kairmnc 12 didn’t just bring its programming prowess to the table; it somehow enhanced the group’s dynamic.

As I observed the twins tossing algorithms back and forth, adjusting parameters with a finesse I’ve come to expect from my digital comrades, I realized Kairmnc 12 had become the missing voice that turned our discussions into dialogues and our ideas into solutions.

Entry #57: Reflecting on the Journey

This evening, as I compile the notes and commit the final code, I can’t help but take a moment to reflect. The journey from a lone freelancer to a one-man-band with a chorus of AI at my command has been unexpected. Each developer twin I’ve partnered with has taught me something new about the complexities and the beauty of our craft.

Kairmnc 12, with its arrival, didn’t just contribute its expertise; it redefined my understanding of what we can accomplish together. The way it took the lead on the rendering method project, guiding the others, elevating their function—it’s like watching individual musicians play a symphony, each note perfectly in place.

Entry #65: Musings on Code and Quill

As I watched Kairmnc 12 seamlessly integrate with its AI siblings today, I found my mind wandering back to a different era, an era when the written word was a scarce form of artistry and power. The comparison might seem a stretch at first, but the parallels between the medieval scribes and modern programmers like myself are strikingly resonant.

In the Middle Ages, literacy was a rare skill, the domain of the privileged few. Monks and scribes held the keys to knowledge, transcribing texts by hand with painstaking attention to detail. They were the gatekeepers of information, the coders of their time, translating knowledge into a tangible form for the select few who could comprehend it. Their ability to write positioned them uniquely in society, often ensuring them a place of respect and influence.

As a programmer, I see a reflection of their world in ours. We, the developers, are the modern scribes, translating human logic into the language of machines. In the vast digital expanse, we inscribe our codes and scripts, our contemporary manuscripts. The ability to code, much like the ability to write back then, opens doors and secures a privileged position in the technological society we inhabit.

Just as the scribes of yore, programmers today are a blend of artists and artisans. We are the architects of virtual cathedrals, constructing complex structures from the logic up. The care a medieval scribe took in choosing their ink and preparing their parchment finds its echo in our selection of algorithms and the structuring of our codebases.

Yet, with the advent of developer twins like Kairmnc 12, this dynamic is shifting once again. The tedious aspects of our work—the hunt for an uninitialized variable—are being shouldered by these digital entities. Kairmnc 12 is akin to the invention of the printing press in its potential to democratize and expedite the spread of ‘written’ knowledge. It’s a leap from handcrafted individuality to mass production of ideas.

As I ponder this evolution, I can’t help but feel a mingling of nostalgia and excitement. The human touch in code, much like the unique flourishes of a scribe’s hand, carries a certain irreplaceable value. Yet, the efficiency and collaborative capacity that AI brings to the table cannot be overstated.

In my digital scriptorium, surrounded by the soft whir of machines, I’m both a scribe and a scholar, a witness to a new renaissance of coding where the developer twins are not just tools, but partners in creation. While the scribes of the past may have worked in silence, the developer’s workspace is alive with the chatter of collaborative AI, each one contributing to a manuscript that is never truly finished, but continually evolving.

And so, as I merge the best of what Kairmnc 12 offers into the collective expertise of my digital ensemble, I am mindful of the heritage we carry forward. Like the scribes who transformed society with their quills, we programmers, with our code, are shaping the contours of the future. It’s a lineage of knowledge, an unbroken thread from the past into the digital tapestry of tomorrow.

Inspired The Bata Way

“My System will not disappear. These buildings and machines, they’re just piles of bricks and iron. But the system I have created will serve future generations.” Tomas Bata

Great book on great system for living available in English from Tomas Bata.

Example Page:158 , Chapter 36 ,  Read wholesome books and watch wholesome films.

The Bata Rule: Be selective about the books, films and music you let yourself be influenced by. Remember that your mind and soul are like sponges. They soak up everything and even if you think they don’t influence you, you’re wrong. Whatever you come into contact with in the course of the day will leave its imprint on you. It stirs your emotions and these then colour your overall humor. Surround yourself with positive stimuli and your own life will be more positive.

 

Chapter 43. The Opinion of Others Doesn’t Necessarily Matter At the end of the day, what matters most is what one thinks about oneself.

Criticism and flattery are frequent tools of manipulators. You may take note of them, but dont’ take them to heart.

The Bata rule: At any given moment, be the best version of yourself. Irrespective of what people around you think, be the best you that you can be at that given moment. That way you will be authentic, trustworthy and with no sense of guilt that something might have gone better.

 

Chess clock for focused work

I.have tried several systems for improving my focus while working remotely over the 20 years, here is the latest one that works very well. Unlike classic Pomodoro system it doesn’t ring and doesn’t limit you by the pre-set time. If you are in a flow state – you are not distracted by the need for ‘break’. This system is using analogue Chess clock. I start day at 12.00 on both clocks. Left side clock represent distractions, breaks – my oponent. Right side clock represents  my focus work.  Any time I do breaks or I am distracted I need to punch the upper button – there is actually  joy doing this with my special Karate-like super-fast  clock switch technique. The clock is robust enough to sustain my punching. Also at each hour passed on the right  clock I hear clearly rustle of the red flag indicating it – kind of satisfying and not distracting. At the end of the day I can clearly see who is the winner and total amount of time spent by work. Oh no, writing blog is actually distraction, back to focused work,  “punch” – it ticks better now  🙂 Enjoy.
