64 posts held, back to 4 August 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 17 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 57 of 64 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.
698 reactions across 57 posts, in 20 distinct kinds. The most used accounts for 32.7% 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 57 of the 64 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 698reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 64 most recent posts we hold, published 4 August 2026 to 12 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.

✅ ПРАВИЛЬНЫЕ РЕШЕНИЯ: 1. Функция range(1, 5) в Python перебирает числа от 1 до 4 включительно (верхняя граница не берётся). Число 5 в цикл не попадёт. Код выведет [1, 4, 9, 16]. 2. В if type(i) = str использован одиночный знак равно =, который является оператором присваивания. Для сравнения типов необходимо использовать двойное равно ==. 3. Не указано x in перед названием списка. Правильная запись должна быть: [x * …
НАЙДИТЕ ОШИБКУ В РЕШЕНИИ 🔎 5. Дана программа, которая преобразует список слов, оставляя только те, длина которых больше 3 символов: words = ["it", "python", "code", "ai"] len_words = [w for w in words if len(words) > 3] print(len_words) Что будет выведено на экран? Решение: Генератор проверяет условие len(words) > 3. Программа выведет: [ 'python', 'code' ].

НАЙДИТЕ ОШИБКУ В РЕШЕНИИ 🔎 4. Дана программа, которая преобразует список строк в список чисел: str_num = ["10", "20", "30"] ints = [int for x in str_num] print(ints) Что будет выведено на экран? Решение: Генератор списков перебирает строки из списка str_num. На каждом шаге функция int() преобразует текущую строку x в целое число. Программа выведет список чисел [10, 20, 30].

НАЙДИТЕ ОШИБКУ В РЕШЕНИИ 🔎 3. Дана программа, которая удваивает каждое число из списка: numbers = [1, 2, 3, 4] d = [x * 2 for numbers] print(d) Что будет выведено на экран? Решение: Внутри генератора списков берется каждый элемент x из исходного списка numbers умножается на 2. Затем результаты собираются в новый список d. Программа выведет на экран удвоенные значения [2, 4, 6, 8].

НАЙДИТЕ ОШИБКУ В РЕШЕНИИ 🔎 2. Дана программа, которая фильтрует список и оставляет только строки: list = [10, "hello", 20, "world"] strings = [i for i in list if type(i) = str] print(strings) Что будет выведено на экран? Решение: Программа проверяет тип каждого элемента в списке list. Если тип элемента равен str, то этот элемент добавляется в новый список strings. Числа 10 и 20 проверку не пройдут. Программа завер…
НАЙДИТЕ ОШИБКУ В РЕШЕНИИ 🔎 1. Дана программа, которая создает список квадратов чисел от 1 до 5: squares = [x**2 for x in range(1, 5)] print(squares) Что будет выведено на экран? Решение: Генератор списков перебирает числа из диапазона range(1, 5). Программа выведет список квадратов: [ 1, 4, 9, 16, 25 ].

Showing the 12 most recent of 64 posts we hold for @informatik_bu. 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 6 most recent of 12 polls we hold for this entry, as Telegram rendered them when we read the post. A poll’s figures keep moving after that, so each one is dated.

Percentages only — there are no per-option vote counts here, because Telegram publishes none.The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.
The shares need not add up to 100.Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.
Read from the 64 most recent posts we hold, published 4 August 2026 to 12 August 2026. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.
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.
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.
This channel appears in 1 seed channel's Telegram-generated recommendation list in total. Each is Telegram’s list for THAT channel, not this one — see how this is measured.
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 13 August 2026 — this entry's latest reading, not the date you are reading this.
