Technology — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 11 September 2026 and assigned it the closest of 31 fixed categories, at 72% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and why it has no browse page of its own yet.

32 posts held, back to 29 July 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 33 pages 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 32 posts for this entry, the most recent from 28 August 2026. An engagement rate over an empty window would be a number about nothing.
Measured directly from 3 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.
444 reactions across 32 posts, in 5 distinct kinds. The most used accounts for 38.7% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 172 | 38.7% | |
| 👍 | 140 | 31.5% | |
| 🔥 | 125 | 28.2% | |
| 🤝 | 6 | 1.35% | |
| 👎 | 1 | 0.225% |
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 32 of the 32 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 444 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 32 most recent posts we hold, published 29 July 2026 to 28 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Собираем простой шаблонизатор строк на Java! Нужно заменить плейсхолдеры вида {name} и {orderId} значениями из Map. Если значение отсутствует, оставим плейсхолдер как есть, чтобы ошибка была заметна в итоговом тексте. В этой задаче: • находим плейсхолдеры через Pattern • достаём имя переменной из группы • безопасно подставляем значение Такой шаблонизатор полезен для писем, логов, уведомлений, CLI-сообщений и генер…

Хорошая статья про JWT-авторизацию на Spring Security! Автор показывает, как собрать авторизацию через access tokens и связать Spring Security с регистрацией, логином, ролями и проверкой токена в защищённых запросах. В статье автор показывает: • как настроить регистрацию и вход пользователя • как выпускать и проверять JWT-токен • как подключить фильтр авторизации к SecurityFilterChain Продолжай читать на Habr 👉 …

Как в Java чище проверять тип через pattern matching? Раньше при проверке типа часто писали так: if (value instanceof String) { String text = (String) value; System.out.println(text.length()); } Код рабочий, но в нём есть лишнее приведение типа. Сначала Java уже проверила, что value это String, а потом мы всё равно руками делаем cast. В современном Java можно записать короче: if (value instanceof String te…

Шпаргалка по устройству JVM! Например, Heap хранит объекты и делится на young/old generation, а Stack содержит фреймы вызовов, локальные переменные и работает отдельно для каждого потока. На картинке основные области памяти JVM: Heap, Stack, Metaspace, PC Register и Native Method Stack, а также краткая логика работы GC и сравнение популярных сборщиков мусора.

Почему Collections.unmodifiableList не делает настоящую копию? В Java часто нужно отдать список наружу так, чтобы вызывающий код не мог его изменить. Например, из getter-метода, DTO, настроек или внутреннего состояния сервиса. Для этого часто используют Collections.unmodifiableList. List<String> roles = new ArrayList<>(); List<String> view = Collections.unmodifiableList(roles); Через view действительно нельзя вызв…

Собираем сортировку задач по зависимостям! Нужно получить порядок выполнения задач, где одна задача может зависеть от другой. Например, сначала build, потом test, а deploy только после test. В этой задаче: • описываем граф зависимостей • считаем входящие связи • кладём свободные задачи в очередь Такой подход полезен для пайплайнов, сборки модулей, миграций, очередей обработки и любых сценариев, где порядок нельзя …

Почему ThreadLocal нужно чистить после использования? ThreadLocal удобен, когда значение должно быть привязано к конкретному потоку: private static final ThreadLocal<String> USER_ID = new ThreadLocal<>(); Например, в начале обработки запроса можно сохранить id пользователя: USER_ID.set("user-42"); А ниже по коду достать его без передачи через каждый метод: String userId = USER_ID.get(); Но в серверных при…

Showing the 12 most recent of 32 posts we hold for @java_ready. 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.
Names
Channels on the register whose handles appear in this channel's posts.
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.
@java_ready named 4 handles that resolve to nothing today. That is a fact about the reference, not necessarily a fact about the handle’s history — see the two groups below.
Most of these may never have existed as a live channel at all. A handle a channel names can be a typo, an aspirational name nobody registered, or a channel that was already gone before this one ever mentioned it. Unless a row below is marked evidenced, all we know is that it references a handle that is not a live channel today — not that anything “died”. How this is measured.
References a handle that is not a live channel — we have no record it ever was one.
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 24 September 2026 — this entry's latest reading, not the date you are reading this.
