Other / unclassifiable — 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 21 September 2026 and assigned it the closest of 31 fixed categories, at 88% 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.

19 posts held, back to 7 April 2025 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page 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 19 posts for this entry, the most recent from 15 May 2025. An engagement rate over an empty window would be a number about nothing.
43 reactions across 9 posts, in 4 distinct kinds. The most used accounts for 58.1% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 25 | 58.1% | |
| ❤ | 15 | 34.9% | |
| 🔥 | 2 | 4.65% | |

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 9 of the 19 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 43 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 19 most recent posts we hold, published 7 April 2025 to 15 May 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
Май — отличное время, чтобы понять разницу между кондиционированием и вентиляцией Нам часто кажется, что в жару достаточно кондиционера, как будто прохладный воздух — автоматически свежий. Нам кажется, что душно и жарко — это одно и то же. Но в мае выключают отопление, в квартирах становится прохладнее, и открывать окна никто не хочет. Через пару дней ощущается недостаток кислорода. Странное чувство — прохладно, но…

Сижу в кофейне, и вот как интересно ребята закрыли наружные блоки кондиционеров. Над входной дверью сделали ниши, изнутри задекорировали, но предусмотрели дверцы для обслуживания. Эффективность работы таких блоков, конечно, ниже. Но это лучше, чем совсем без кондея, тем более в кафе 😎👍 PS. 27 мая старт Клуба AboutDC. Будем отвечать на все ваши вопросы, которые возникают по работе или в быту :)

Заметил, что в СП 60 увеличили допустимое соотношение сторон прямоугольного воздуховода. Раньше всегда брали не более 1:3, теперь не более 1:4 Прямоугольные воздуховоды вообще-то менее эффективны, чем круглые, но используются для экономии высоты воздуховода, а также при больших сечениях. Чем более расплющен прямоугольный воздуховод, тем менее он эффективен. Фактически, нынешний СП 60 допускает использование менее э…

Для желающих потренироваться — задачка из домашнего задания на Курсе Промышленной вентиляции: Температура приточного воздуха Тприт = 20С Температура вытяжного воздуха Твыт = 25С В помещении работает 10 сотрудников. Фоновые теплопритоки 5 кВт Локальный теплоприток от оборудования 10 кВт Около оборудования установлена локальная вытяжка (местный отсос) с расходом 1000м3/ч, температура локальной вытяжки 40С Какой расхо…

Четыре варианта расчета вентиляции Коллеги, в нашей практике встречается 4 основных способа расчета вентиляции: 1. По кратностям (1,2,3 крата на вытяжку и/или приток в зависимости от помещения; точные цифры указаны в нормативах) 2. По людям (20, 30, 60, 80 м3/чел в зависимости от того, посетитель это, временно пребывающий, постоянно пребывающий или спортсмен) 3. На удаление теплоизбытков (чтобы не было слишком жарко…

Из опыта Объекты делятся на приточные и вытяжные [да-да, не системы, а объекты тоже; неформально, конечно]. В приточных типоразмер системы задаёт приток (обычно по людям), а вытяжку подгоняют под него (по нормам из санузлов и технических помещений; остаток -- из комнат с людьми). В вытяжных типоразмер системы задаёт вытяжка (обычно по расчету на удаление вредностей или тепла), а приток уже подгоняют под неё. С 2…

Showing the 12 most recent of 19 posts we hold for @aboutdc. 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 3 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.

Shares as published, totalling 101%. No per-option vote count is published by Telegram, so none is shown.
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 19 most recent posts we hold, published 7 April 2025 to 15 May 2025. 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.
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 12 October 2026 — this entry's latest reading, not the date you are reading this.
