ChatGPT analyzed my interest and created a cool poster!
We're excited to share that revotale.com scored 96 on mobile PageSpeed Insights! Even better — the blog notes page hits a perfect 100 🎯
It took some fine-tuning, but it was absolutely worth it.
Here’s what’s powering our performance:
We see this as a foundation — keeping our performance scores high will remain a core principle as we grow. It won’t always be easy, but we believe this discipline will bring long-term benefits across the board.
If the site generates tons of low-value, unique search URLs (e.g., from bots or typo queries), consider:
<meta name="robots" content="noindex, follow">
But if you expect users to search the same queries again or want to rank for long-tail queries, keep it indexable.
I’m excited! Thanks to GitHub Copilot, I can now automate the process of finding missing translations across the project. Instead of using complex utilities or manually reviewing everything, now I just need a simple prompt.
So, the problem was that GitHub markdown files do not respect image width in case content is shorter than image. Thanks to HTML. There is " " filler in HTML specification that does role of "Non-breaking invisible glue" so it can simulate table width in case there is not enough symbols in table cell content.
The neocortex, which evolved relatively recently, is located on the surface of the brain. Proportionally, this level occupies more space in the brains of primates than in those of other animal species. Cognition, memory storage, sensory processing, abstraction, philosophy, self-reflection — all reside here.
Read a terrifying passage in a book, and level 3 will signal level 2 to make you feel fear, which in turn will instruct level 1 to initiate trembling. Watch an Oreo commercial, and you’ll feel the urge to eat it — that’s level 3 influencing levels 2 and 1.
Think about the fact that your loved ones (or children in a refugee camp) won’t live forever, or that the tree of the Na’vi in Avatar was destroyed by those awful humans (even though — wait, the Na’vi aren’t real!), and level 3 will engage levels 2 and 1, making you feel sorrow, with a stress response as if you were running from a lion.
This region evolved later and developed in mammals. MacLean explained that this level is associated with emotions — a kind of mammalian invention. If you witness something brutal and horrifying, the neural structures at this level send a signal to the ancient level 1, making you tremble with emotion. If you’re heartbroken over unrequited love, areas here nudge level 1 to trigger cravings for unhealthy food. If you’re a rodent and hear a cat, neurons in this region push level 1 to initiate a stress response.
The ancient component of the brain — its foundation — is present across a range of species, from humans to geckos. This level controls automatic regulatory functions. If body temperature drops, this part of the brain responds by instructing the muscles to shiver. If blood glucose levels fall, it’s detected here too, triggering the sensation of hunger. If a person experiences an injury, another neural center at this level initiates a stress response.
Attention! These are NOT literal layers of the brain.
Let’s begin by examining the macro-organization of the brain. For this, we’ll use a model proposed in the 1960s by neuroscientist Paul MacLean. His “triune brain” model describes the brain as having three functional domains:
So, our brain is divided into three functional blocks, with the usual advantages and disadvantages that come with categorizing any continuum. The biggest drawback is its excessive simplification.
Level 1: The ancient component of the brain — its foundation — present across various species.
Level 2: A region that evolved later and developed in mammals.
Level 3: The neocortex, which evolved relatively recently and is located on the surface of the brain.
Anatomically, there is significant overlap between these three levels (for instance, one part of the cortex could be considered part of level 2 — more on this later).
The flow of information and commands doesn’t just move top-down, from level 3 to 2 and 1. One strange and interesting example we’ll explore in Chapter 15: if a person is holding a cold drink (temperature processed by level 1), they are more likely to perceive a new acquaintance who approaches them as a “cold” person (level 3).
The automatic aspects of behavior (in simplified terms — the domain of level 1), emotions (level 2), and thinking (level 3) are inseparable.
The triune model gives the misleading impression that evolution simply stacked one level on top of another, without any changes to the ones that already existed.
Despite all its flaws — which MacLean himself acknowledged — this model will serve as a useful organizational metaphor for us.
