Why I created another markup language

Why I created new markup language? Link to heading

Yet another time to call something “yet another” this time it is markup language. Yet another markup language… Why?

Current Link to heading

HTML/XML is fair example. They are in essence as simple as it gets.

All that marking up was in days of early web to state what is what in mostly textual files and allow search engines to index it properly. Later on HTML became the most coupled tech in existence having some tags with semantic meaning, some with presentation meaning and some with both, then script tags and what not. This is because it was repurposed to follow the ever growing needs of web.

Intro — formal languages and parsing Link to heading

All programming languages are specified by a grammar. A grammar tells us whether a piece of text is a valid sentence in that language. A parser generator can take such a grammar and produce a parser. Parsing is the “front end” of compilation: it turns raw text into structure. That’s the basis of how formal languages work.

Every user flow e2es - model-based testing / state-machine testing

Intro Link to heading

What an exiting and strange time we live in! At the same time streets are poverty struck resembling void of beauty, and I can play with miniature special purpose machine brains sitting on gigantic legacy of modern computing. Words really is battlefront of light and dark. One of such brains can be constructed and used in app testing purposes.

Every user flow e2es - model-based testing / state-machine testing Link to heading

is end boss dream of e2e testing. Covering every user flow is implementationally demanding. On top of it Teams claim e2es are demanding to maintain. So they opt out. Interestingly solution lies, as its often case in life, there where we don’t want to look at.

Language agnostic steno theory

What a glorious weekend. What a joy. In two days I implemented

language agnostic steno theory

There is code at the bottom but lets focus on the theory first.

My take on why steno is appealing Link to heading

200 wpm non invasive hmi. Full words: 200 words per minute without a chip and usb port in your head interface for commanding a machine. Basically thought speed interface. Appealing. As short as that! A chip in your heard has r/w and idea of w in my head already creeps me out even without a chip so no thank you. So demanding muscle memory training it is.

Tradeoffs of Module Management

Tradeoffs of Module Management Link to heading

We all want reusability—until we’re in a hurry.

Or under-skilled.

Or just trying to ship something today instead of tomorrow.

Reusability takes extra thought, extra structure, and a level of patience most developers can’t afford in the moment.

So what do we do instead? We reach for the batteries-included approach.

npm install becomes our reflex. Install a library for everything—debounce, isEqual, date formatting. You end up with three different utilities solving the same problem… and use none of them.

Automation Doesn’t Work for You – And That’s By Design

Automation Doesn’t Work for You – And That’s By Design Link to heading

Automation is Power.

This truth was carved into history when Alan Turing and others turned machines into war-winning tools. Those who mastered automation during wartime gained world-scale leverage. The ability to process and act faster than your enemy became the new axis of power. Such is the scale of automation.

Fast-forward to today. You have more raw computational power in your pocket than Turing had in all of Bletchley Park. You have access to programming languages, cloud infrastructure, and libraries of logic once reserved for elite scientists.

The missing development metric - UX complexity

The missing development metric - UX complexity Link to heading

While everyone, ok not every one is talking about computational complexity. Especially in high level languages with accent to functional programming.Recomputation is the name of the game. So even on that old topic a lot could be said. But UX complexity - the cost of interaction as arguably the most important metric and its not yet a termed metric. Let’s face it, if you nailed UX complexity, you nailed computational complexity long ago.

Hype Debunking: FP vs IP, Microservices vs Monoliths

Hype Debunking: FP vs IP, Microservices vs Monoliths Link to heading

There is a huge parallel between:

functional vs imperative programming
microservices vs monoliths

Now, the most unwelcome thing—dogma—should have no foothold in the software world. But it does.
Just like other markets, we ride waves of virality. It’s no coincidence that most beginners choose the most popular frameworks and languages.

While this kind of marketing gives guidance, it destroys the very essence of what coding should be: sense.
So parrots fly around and repeat things like:

JS spread performance ⚠️warning Link to heading

Us web devs, we often speculate syntax based on “best practices” bestowed upon us by the Gods of - meme lords. We praise our prettier and linters as basis of all success. Looping between all 22 and a half options of a drop down allows you to use exponential complexity implementations. In a loop. Because even if you have 2k entries thats a warmup for one core. So in all wire connections between types, runtime validators, component props, api responses and requests, rarely in fact implementation matters from performance standpoint. Except when it does.
