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.

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.

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 28 most recent posts we hold, published 1 July 2026 to 20 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.

Копируем диск по сети одной командой Без создания промежуточного образа На принимающей машине: nc -l 9000 | dd of=disk.img На отправляющей: dd if=/dev/sda | nc <IP_получателя> 9000 Так можно передавать целые диски или разделы напрямую по сети. Внимательнее к dd: ошибка в имени устройства может привести к потере данных.
🔐 Средства защиты в ядре Linux — это фундамент безопасности всей системы. Если вы хотите понимать: ❔ как защищается ядро; ❔ почему работают SELinux, AppArmor, KASLR и PTI ❔ как проверить защищённость системы на практике, этот практикум для вас. 🗓 20 августа в 20:00 МСК приглашаем вас на открытый урок в преддверии старта курса «Разработка ядра Linux». Разберём: • модели DAC и MAC; • механизмы защиты ядра; • парамет…
Следим за изменениями в папке в реальном времени Установи inotify-tools и выполни: inotifywait -m ~/Downloads Теперь любое создание, удаление, переименование или изменение файлов будет сразу отображаться в терминале. Отлично подходит для автоматизации и написания скриптов.
Быстро создаем RAM-диск sudo mount -t tmpfs -o size=2G tmpfs /mnt/ramdisk Все файлы в /mnt/ramdisk будут храниться только в оперативной памяти, что обеспечивает очень высокую скорость работы. После перезагрузки содержимое исчезнет. Это удобно для временных файлов, сборки проектов и тестирования.
Узнать, какие файлы открывает программа Если интересно, что происходит «под капотом» при запуске приложения, воспользуйтесь strace. strace -e openat firefox Опция -e openat выводит только системные вызовы открытия файлов, отбрасывая тысячи других операций. В выводе можно увидеть, какие библиотеки, шрифты, конфигурационные файлы и другие ресурсы пытается открыть программа. Например: openat(AT_FDCWD, "/etc/hosts",…
Мало опыта, но есть горящие глаза и желание строить будущее в атомной отрасли? 👌Росатом приглашает студентов и выпускников вузов на 5 бесплатных обучающих программ – кейс-лабораторий, лучшие участники которых попадут на конференцию «ИТ КоР 2026», применят полученные знания в финальном хакатоне и получат приглашения на работу в ведущие ИТ-компании атомной отрасли. Направления кейс-лабораторий: ✅1С-разработка; ✅Java…
Смонтируем каталог в другом месте без копирования mount --bind /home/user/projects /mnt/projects После этого содержимое /home/user/projects будет доступно и через /mnt/projects. Удобно для контейнеров, chroot, резервного копирования и нестандартных сценариев настройки.
Можно временно изменить время только для одного процесса. LD_PRELOAD=/usr/lib/x86_64-linux-gnu/faketime/libfaketime.so.1 \ FAKETIME="2035-01-01 12:00:00" date Или использовать утилиту faketime: faketime "2035-01-01" ./program Полезно для тестирования лицензий, сертификатов и логики работы с датами.
Читать сжатые файлы без распаковки Необязательно сначала распаковывать архив, чтобы посмотреть его содержимое. Для файлов .gz можно использовать: zcat logfile.gz или читать постранично: zless logfile.gz Для поиска по содержимому подойдёт: zgrep ERROR logfile.gz Это особенно удобно при работе с архивированными логами, которые могут занимать несколько гигабайт. Важно: less archive.tar.gz не покажет содержимое архив…
Bash умеет открывать TCP-соединения без дополнительных программ. Например: exec 3<>/dev/tcp/google.com/80 echo -e "GET / HTTP/1.1\r\nHost: google.com\r\n\r\n" >&3 cat <&3 Это настоящий HTTP-запрос, выполненный средствами Bash. Работает и для проверки портов: echo >/dev/tcp/192.168.1.1/22 && echo "Порт открыт"
Выполнение команд в несколько потоков с xargs По умолчанию команды обрабатываются последовательно. Если задача не зависит от порядка выполнения, её можно распараллелить и задействовать сразу несколько ядер процессора. Например: seq 1 100 | xargs -P8 -I{} echo {} Параметр -P8 разрешает одновременно запускать до 8 процессов, а -I{} подставляет каждое значение на место {}. Более практичный пример — сжатие нескольких …
Showing the 12 most recent of 28 posts we hold for @os_linux_ru. 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.

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.
