Topic

Education — 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 14 September 2026 and assigned it the closest of 31 fixed categories, at 98% 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.

13 measurements spanning 43 days, net +10. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 3,435–3,448 and does not start at zero.

Engagement

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 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 20 posts for this entry, the most recent from 5 August 2026. An engagement rate over an empty window would be a number about nothing.

Reaction mix

16 reactions across 9 posts, in 5 distinct kinds. The most used accounts for 25.0% of them.

Every reaction kind recorded on the sample, most used first

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 16 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 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,…

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…

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.

Forward network

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.

Mentions

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.

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.

Appears in Telegram’s recommendations for other channels

The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
