В Nature вышла интересная статья (pdf), в ней рассматрели «человеческий язык» как инструмент для передачи информации и пришли к выводу, что это клевый способ для коллаборативной работы нас как вида (и шитпоста в интернете), но язык не нужен мозгу для «мыслительного процесса»
Я никогда не задумывался, как выглядит «мысль» если исключить из нее «язык», поэтому вот пару интересных наблюдений из статьи о том как устроен процесс мышления:
1. Мысли, вероятно, опираются на абстрактные, неязыковые ментальные представления. Это могут быть визуальные, пространственные или другие специфические представления под конкретные задачи и концепции. Как человек, который в любой момент времени может вспомнить любой маршрут по которому я ходил где-то и был трезвый, могу сказать что все так, у меня «карта местности» просто существует в виде образа в голове, как оказалось, так не у всех
2. В голове есть ансамбль нейронок — в статье упоминается несколько «мозговых сетей», участвующих в различных задачах:
— Есть нейронка «множественных требований» для целенаправленного поведения и решения новых задач, она поощряет находчивость при решении проблем, активируется при выполнении когнитивно сложных задач, особенно тех, которые требуют гибкого мышления и адаптации к новым ситуациям. Она же отвечает за планирование и рабочую память;
— Есть нейронка «теории разума» или «эмпатии»: для социального рассуждения и понимания психических состояний – мыслей, чувств, убеждений и намерений других людей. Это та, которая у нас уже хуже чем в GPT4o;
— Есть «Дефолтная нейронка», активируется когда мозг в покое – связана с кучей когнитивных штук, включая: способность мысленно перемещаться во времени (вспоминая прошлое или представляя будущее), пространственное познание, размышление о себе, своих чертах и опыте. Интересно, что повреждение это "сетки" ведет к депрессии или даже шизофрении (в теории).
3. Символическое мышление может происходить без языка как инструмента. Это означает, что мозг может манипулировать абстрактными символами или концепциями, не опираясь на слова или грамматические структуры. Условно, когда вам что-то «пришло в голову из неоткуда», это этот эффект.
4. Рассуждение по специфичным задачам — разные типы мышления (математические, социальные, пространственные и т.д.), по-видимому, задействуют разные мозговые «нейронки», что предполагает, что процессы мышления могут быть в некоторой степени модульными и специфичными для конкретных задач; это как если бы у одной мощной LLM было много Lora натренированных на конкретных задачах датасета, а не единая модель для решения всех задач.
5. Параллельная обработка — все эти «нейронки» для решения специфичных задач (социальные, причинно-следственные, решение проблем и т.д.) могут работать параллельно, получая при этом информацию с разных «сенсоров» тела, а не определяться единой системой, такой как язык.
6. Мы сильно похожи на животных — в статье упоминается непрерывность человеческой эволюции, предполагая, что наши процессы мышления могут быть более похожими на процессы мышления других животных, чем считалось ранее, просто они оказались более сложными из-за наших расширенных когнитивных способностей. То есть, условная собака может оказаться намного ближе к нам по процессу мышления чем мы раньше думали.
7. Культура развивает мышление — хоть это и не прямой механизм мышления, в статье упоминается что передача культурных знаний от поколения в поколение, повышает когнитивные способности человека с течением времени, это уже влияние языка как инструмента.
Короче, все еще ничего не понятно — но на всякий случай продолжайте тренировать лоры☕️

Hey everyone! It’s been a while since my last update. Life’s been a whirlwind, and I haven’t had much time to be a content creator 🤪
Recently, I made a presentation about streams in browsers, and I want to share some of those ideas with you here.
Multithreading(web workers) in web projects is a game-changer, yet I rarely see it utilized. It can significantly lighten the main thread’s load and make web applications more dynamic and responsive. So, where and when can it be used?
1. Complex Calculations🖥
Heavy computations often block the main thread, causing the page to freeze or even crash. Offloading these tasks to web workers can prevent this. For example, if you’re processing large datasets to create a graph, you can delegate the calculations to a worker. The worker processes the data and returns only the (x,y) coordinates, which you can then easily plot.
2. Real-Time Analytics📊
Perfect for traders! Imagine writing a custom plugin that monitors the market in real-time, providing notifications or triggering actions when certain conditions are met. Using web workers ensures that the main thread remains free for other tasks.
3. Image Processing📷
Tasks like applying filters, cropping, and other image manipulations can be offloaded to web workers, making the main thread available for smoother interactions.
4. Inter-Tab Communication💬
Need to synchronize actions across multiple tabs? For instance, logging into one tab could automatically trigger an “authorized” status event in other tabs. Web workers can help manage these tasks efficiently.
These are just a few examples of how web workers can make your web projects faster, smarter, and more efficient.
However, there are some drawbacks, like the lack of direct access to the Browser API and the need to use an event-driven pattern. But the benefits far outweigh the challenges!
I hope this sparks some ideas for your own projects!

Random info about our Earth 🌍
All of Earth’s water, if gathered into a single sphere, would have a diameter of about 1,386 km! This sphere includes all oceans, ice caps, rivers, groundwater, and even the water in the atmosphere and living organisms. Despite the vast oceans, Earth’s water is just a thin layer compared to the planet’s size.

Why is the Developer Doing Everything? 🤔
Ever feel like you’re the team’s Swiss Army knife, doing everything from coding to setting up the coffee machine?
1. Developer = Jack of All Trades
We code, we test, we even do a bit of design! With a skill set like ours, it’s no wonder tasks keep landing on our plate.😓
2. Small Team, Big Expectations
In startups, there’s no budget for specialists, so who’s going to handle it all? Yep, you guessed it—us.💪
3. “Just Give It to the Dev” Syndrome
Without clear roles, everything from bug fixes to Friday night pizza orders ends up being a developer’s responsibility.🍕
4. Communication Struggles
Sometimes it feels like “the dev will figure it out” is the team’s unofficial motto.😅
5. Expectations Galore
When you’re a key player, it’s like there’s a neon sign over your head saying “Dump Tasks Here.”🛑

In the next couple of decades, we will be able to do things that would have seemed like magic to our grandparents.
You've thought you can hide from the Big Brother? Escaping from Matrix getting harder and harder
From Mr. Durov's post
🐶 BTW, Telegram encryption works only in secret chats, but since they have your IP and phone number, there’s more at play behind the scenes. While secret chats boast end-to-end encryption, standard conversations are stored on Telegram’s servers, accessible by the platform itself. This raises concerns about how secure your data truly is, especially when combined with metadata like your IP address and phone number.
Who has access to this information, and what are they doing with it?
Could these seemingly innocuous details be the key to uncovering deeper insights into your identity or tracking your movements in ways you’re unaware of?
However, you can relax until you are not interesting to the Gov. 🙂

You're given an array of integers a and two integers x and y. Count the number of elements in the array such that `x ≤ a[i] ≤ y, where i is the 0-based index of the element.
Seems easy, but:
code limit: less than 48 characters.
This is like an average business task: the task gets solved, but unnecessary stuff always seems to get in the way.😂

News about a disturbing response from Gemini, has gone viral with headlines like "Humanity – Over," "Beginning of the End," and similar phrases.
I reviewed the chat and noticed that this user had little understanding of how to prompt effectively. Here are the last of their messages:
The final response from Gemini:
What actually happened?
1. The chat’s context drifted, likely due to the lack of clear instructions for the model.
2. The frequent discussion of violence topics may have influenced the model's responses in an unintended direction.
To avoid hallucinations or nonsensical responses from chat models:
1. Keep different topics in separate chats.
2. Provide clear instructions about what you expect in an answer.
You can replicate this kind of scenario by mixing unrelated topics in one chat, contradicting yourself, and the model may start producing confusing responses!

Don't Overthink, Start Solving! 💡
When faced with a complex task, it's easy to overthink and get lost in endless solutions. But here's the key: just start solving!
Once you get the correct result, it's time to optimize.
Bit by bit, refine your code—make it more readable, maintainable, and sometimes even faster (but not always😉 ).
Here is an example:
Task is
Solution optimizing evolution
First version, which works, but its a big unreadable code
Nasty...
Implementing DRY and Divide-and-conquer:
Looks much better. But something is missing, and looks like we overdoing something...
Removing unneeded
Final solution looks 10 times better, much more readable and well structured🗣

Here is an example:
Task is
Implement a function that receives two IPv4 addresses, and returns the number of addresses between them (including the first one, excluding the last one).
All inputs will be valid IPv4 addresses in the form of strings. The last address will always be greater than the first one.
Solution optimizing evolution
First version, which works, but its a big unreadable code
// first version
export function ipsBetweenV1(start: string, end: string): number {
const reversedStart = start
.split(".")
.reverse()
.map((segment) => parseInt(segment, 10)) as number[]
const reversedEnd = end
.split(".")
.reverse()
.map((segment) => parseInt(segment, 10)) as number[]
const amountInStart = reversedStart.reduce((acc, curr, index) => {
acc += curr * Math.pow(256, index) + 1
return acc
})
const amountInEnd = reversedEnd.reduce((acc, curr, index) => {
acc += curr * Math.pow(256, index) + 1
return acc
})
return amountInEnd - amountInStart
}
Nasty...
Implementing DRY and Divide-and-conquer:
// second version
export function ipsBetweenV2(start: string, end: string): number {
const getReversedSegments = (ip: string) => {
return ip

const calcAmountInIps = (ips: string) => {
return getReversedSegments(ips).reduce((acc, curr, index) => {
acc += curr * Math.pow(256, index) + 1
return acc
}) as number
}
return calcAmountInIps(end) - calcAmountInIps(start)
}
Looks much better. But something is missing, and looks like we overdoing something...
Removing unneeded
reverse(), and simplifying functions into one with readable structure:export function ipsBetween(start: string, end: string): number {
const ipToNumber = (ip: string): number =>
ip.split(".").reduce((acc, curr, index) => acc * 256 + parseInt(curr, 10), 0);
return ipToNumber(end) - ipToNumber(start);
}Final solution looks 10 times better, much more readable and well structured
