20 posts held, back to 19 September 2025 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 10 November 2025. An engagement rate over an empty window would be a number about nothing.
3 reactions across 1 post, in 2 distinct kinds. The most used accounts for 66.7% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 2 | 66.7% | |
| 💩 | 1 | 33.3% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 1 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 3 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 19 September 2025 to 10 November 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Чистая архитектура нужна, чтобы проект был структурированным и удобным для поддержки. Слой data отвечает за получение и хранение данных (DTO, репозитории, API), domain — за бизнес-логику и правила работы (доменные модели, Use Case), а presentation — за отображение и взаимодействие с пользователем (ViewModel, экраны, LiveData). Каждый слой содержит только свои элементы, чтобы код оставался чистым и легко изменяемым.
ответ
Для чего нужна чистая архитектура? За что отвечают слои data, domain, presentation? Какие элементы обязательно должны быть в этих слоях? Нужно привести пример из кода, и ответить своими словами. Можно перечислить обязательное содержимое каждого слоя
// Доменная модель data class User(val id: Int, val name: String) // Интерфейс репозитория (domain слой не зависит от реализации) interface UserRepository { suspend fun getUserById(id: Int): UserDTO } // Mapper: DTO -> Domain fun UserDTO.toDomain(): User { return User(id = this.id, name = this.username) } // Use Case: бизнес-логика — получение пользователя по ID class GetUserUseCase(private val repository:…
Базовый Use Case в слое domain — это класс или функция, которая выполняет одну конкретную бизнес-операцию. Он работает только с domain моделями и не зависит от UI или конкретной реализации репозитория. Use Case получает данные через репозиторий, преобразует DTO в domain модель и возвращает готовый объект для использования в других слоях приложения, например, в ViewModel.
ответ
Как выглядит базовый(обычный) Use case в слое domain? Привести пример из кода
class UserViewModel(private val repository: UserRepository) : ViewModel() { val userLiveData = MutableLiveData<User>() val errorLiveData = MutableLiveData<String>() fun fetchUser() { // Корутина запускается на главном потоке, чтобы можно было обновлять UI viewModelScope.launch(Dispatchers.Main) { try { // Выполняем запрос в фоновом потоке IO va…
В Kotlin Coroutines Dispatcher определяет, на каком потоке выполняется код. Для работы с UI используют Dispatchers.Main, для сетевых или файловых операций — Dispatchers.IO, а для тяжёлых вычислений — Dispatchers.Default. При запросе данных корутина запускается на главном потоке, а сам сетевой или базовый запрос выполняется на IO-потоке через withContext(Dispatchers.IO). После получения данных они преобразуются в doma…

Каким образом указывается Dispatcher для работы корутины? Написать полную обработку запроса с указанием Dispatcher
Showing the 12 most recent of 20 posts we hold for @Kchai. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 21 August 2026 — this entry's latest reading, not the date you are reading this.
