20 posts held, back to 16 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 3 pagesof Telegram’s post history, 20 posts per page.
ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate. It is computed over the 10 of 20 measured posts that carry a reaction reading, and over those same posts' views.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.
16 reactions across 9 posts, in 5 distinct kinds. The most used accounts for 25.0% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 4 | 25.0% | |
| 👍 | 4 | 25.0% | |
| 👏 | 3 | 18.8% | |
| 🔥 | 3 | 18.8% | |
| 👾 | 2 | 12.5% |
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 10 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 16reactions 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 16 July 2026 to 5 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.
COPY vs ADD? COPY для файлов из контекста. ADD ещё умеет tar-распаковку и URL — почти всегда зло. COPY предпочтительнее. ARG vs ENV? ARG виден только на этапе build (не в рантайме). ENV попадает в образ и окружение контейнера. Как уменьшить размер образа? Multi-stage builds, .dockerignore, Alpine/ubi-minimal/Distroless, объединяй RUN, чисти кеши (apt/apk) в том же слое, пинь версии. Библиотека собеса по DevOps

Покупать новый курс каждый раз, когда меняется рабочая задача, — довольно странная механика. Нашли альтернативу 👇
👅 Самое сложное — выбрать не курс, а направление Сегодня хочется разобраться в AI-агентах. Через пару недель появляется задача, где нужны алгоритмы. Потом понимаешь, что неплохо бы освежить Python или математику для Data Science. 🔜 Именно поэтому подписка на обучение многим оказывается удобнее отдельных курсов. Можно спокойно переключаться между темами, когда меняются задачи, а не покупать новую программу каждый ра…
Вы заметили, что контейнеры в продакшене начинают работать медленнее со временем. Мониторинг показывает рост использования диска внутри контейнера, хотя приложение не пишет данные в тома. Как вы будете искать и устранять проблему? Проверить, не накапливаются ли временные файлы или логи внутри контейнера (слои copy-on-write). Использовать docker system df, docker inspect и docker logs для анализа. При необходимости —…
🎯 У разработчика, DevOps-инженера и техлида разные причины задуматься о системной работе с AI-агентами Но цель одна: перейти от случайных удачных запусков к управляемому процессу на реальном проекте — с понятными правилами, ревью, контролем расходов и безопасности ✔️ На курсе «ИИ для разработчиков» участники выстраивают такой процесс на практике: подключают инструменты, задают границы для агента и учатся понимать,…
Разработчик, DevOps-инженер или техлид — у каждого своя причина навести порядок в работе с AI-агентами. Разбираем, чем отличаются их задачи 😊
У вас есть Dockerfile, и сборка образа занимает очень много времени из-за частых изменений в коде. Как оптимизировать процесс сборки, чтобы быстрее получать новые образы? Переписать Dockerfile так, чтобы максимально использовать кэш слоёв: сначала устанавливать зависимости, потом копировать код. Использовать multi-stage build, чтобы в финальном образе были только нужные бинарники и минимальный набор файлов. Библиот…

Вы видите в Kibana после нажатия на «Discover» «561 hits». Что это значит? Общее количество документов, соответствующих результатам поиска. Если не используется запрос, то просто общее количество документов. Библиотека собеса по DevOps

Самый страшный файл в проекте — тот, который «работает, не трогай» 😮💨

У вас в проекте есть файл вроде utils_v2_final_FIX.py, который все боятся трогать ❓ Что делаете с таким легаси? ❤️ Не трогаю: работает — и ладно 👍 Переписываю с нуля и надеюсь на лучшее 🔥 Сначала покрываю тестами, потом рефакторю по частям 👾 У нас такого нет — честно-честно На курсе «ИИ для разработчиков» разберём третий подход: как с помощью агента зафиксировать текущее поведение легаси-кода тестами, а затем меня…

В продакшн-окружении контейнеры начинают потреблять слишком много дискового пространства. Как вы будете диагностировать и устранять проблему? Проверю docker system df, чтобы понять, где расход (образы, volume, build cache). Использую docker ps -s и docker inspect, чтобы выявить, не пишут ли контейнеры данные внутрь слоя файловой системы. Для логов — настрою ротацию (log-driver=json-file с max-size и max-file) или це…

Как внедрить zero-trust между микросервисами? Включите mTLS с распределённой идентичностью (SPIFFE/SPIRE: SVID для каждого ворклоада), автоматическую ротацию сертификатов и валидацию цепочки. Авторизацию стройте по идентичности (RBAC/OPA), ограничивайте сеть NetworkPolicy. В Kubernetes удобно через mesh (Istio/Linkerd/ambient) или sidecarless mTLS; для мультикластера — федерация trust domains и централизованный ауди…

Showing the 12 most recent of 20 posts we hold for @devops_interview_lib. 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.
Citation-graph rank — 646,323 of 1,151,006entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Republishes
Channels on the register whose posts this channel has forwarded.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Named by 5 registered channels — 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.
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.
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 10 August 2026 — this entry's latest reading, not the date you are reading this.
