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 100% 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.
Growth
28 measurements spanning 42 days, net -62. 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 10,714–10,794 and does not start at zero.

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 4 of 5 measured posts that carry a reaction reading, and over those same posts' views.

Readings taken
1 Sept 2026, 20:25 UTC
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.
Reaction mix
190 reactions across 28 posts, in 4 distinct kinds. The most used accounts for 81.1% of them.

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 28 of the 31 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 190 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 31 most recent posts we hold, published 8 July 2026 to 31 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.

An ad marker, not a judgement about a post. A post is counted here because it carries one of two explicit markings: an erid token, which Russian law has required on paid placements since 2022 and which is issued against a specific advertising contract, or a #реклама / #ad hashtag in the body, which is the channel declaring it itself. The first is documentary; the second is a self-declaration and is weaker. No classifier reads the text and decides — nothing on this site guesses that a post is an advertisement.
This is a floor, and it can only ever be a floor. A channel that runs paid placements without marking them produces no marker for us to count, and an unmarked ad is indistinguishable from an ordinary post on the public surface. The ad load above therefore means “the share of posts that declared themselves”, never “the share of posts that were paid for”. A low figure is not evidence of a channel that runs few ads.
Both figures are medians, and no ratio between them is published. Each is a view reading that actually occurred on a post, picked by percentile_disc rather than averaged, so one viral post cannot move it and no interpolated value is invented between two readings. The sample on one side is under five posts, which is too thin to compare. The two figures are shown side by side with the count behind each, and deliberately not divided into a headline like “ads get x% fewer views” — an arithmetic that is easy to print and, at this sample size, means nothing.

A token repeated across several posts is one advertising contract placed more than once, which is what the identifier is for. The strings are reproduced exactly as they appeared in the post or in its click-through URL and are not validated against any registry — we record the marker a channel published, and whether it resolves to a real contract is a question for the register that issued it.
Measured over the 31 most recent posts we hold, published 8 July 2026 to 31 August 2026. Views are the latest single reading held for each post, and any reading at or above 1,000 is rounded by Telegram to three significant figures.
Сервис упал ночью, до утра гигабайт логов. Порядок, в котором в них лезть
Начать с ошибок текущей загрузки
journalctl -p err -b
-b отсекает всё, что было до последней перезагрузки, -p err оставляет уровень Error и выше. Цифровой вариант -p 3 делает то же самое, но словом читается лучше.

Диски гостей раздулись, а внутри места полно. Вернуть его хосту — и не просадить запись
Проверить, поддерживает ли диск discard
lsblk --discard
Нюанс: в подборках советуют hdparm -I /dev/sda | grep -i trim. На virtio-диске это не сработает вовсе — у меня вернуло Operation not permitted, потому что hdparm говорит по протоколу ATA, которого у виртуального диска нет. lsblk --discard показывает нужное для любого тип…
🎥 Вебинар: Первый веб-сервер на Linux: Nginx, Apache и проверка доступности

Как достать пароль из kdbx, когда графика легла и буфер обмена недоступен
Всё проверено на keepassxc-cli 2.7.6 из репозитория Ubuntu 24.04.
Посмотреть, что вообще есть в базе
keepassxc-cli ls -R database.kdbx
Нюанс: без -R увидишь только верхний уровень. Вложенные записи в группах не покажет — легко решить, что база пустая.

Посмотреть, какие интерфейсы подняты, и не принять погасший порт за живой
Краткий статус интерфейсов
ip -4 -br address show up
Нюанс: up фильтрует по состоянию линка, а не по наличию адреса. Погасил eth0 — с ключом он пропал из вывода совсем, без ключа виден как DOWN со всеми адресами на месте. Пустая строка тут не значит «адреса нет».
Второй адрес без алиасов вида eth0:1

Ходовой набор для отладки bash-скрипта известен всем: set -euo pipefail сверху, set -x вокруг мутного места и ловушка DEBUG с read, чтобы останавливаться перед каждой командой. Прогнал этот набор на Ubuntu 24.04, bash 5.2. Три вещи из него ведут себя не так, как ожидаешь.

На открытом уроке разберем, как определить, из-за чего Linux-сервер начал работать медленнее: процессор, оперативная память, дисковая подсистема или отдельный процесс. Познакомимся с базовыми инструментами мониторинга и посмотрим примеры диагностики проблем производительности.
О чем поговорим:
— Какие ресурсы сервера чаще все…
Попалась заметка про reptyr — утилиту, которая забирает уже запущенный процесс в новую сессию терминала. Команды из ходовых инструкций прогнал сам, на двух машинах с Ubuntu 24.04.

Showing the 12 most recent of 31 posts we hold for @LinuxSkill. 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.
