2 measurements spanning 1 day. 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 143–145 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.

Readings taken8 Aug 2026, 21:30 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.

Lifetime counters from Telegram’s own channel header, read 8 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Reaction mix

40 reactions across 17 posts, in 6 distinct kinds. The most used accounts for 57.5% 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 17 of the 17 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 40reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 17 most recent posts we hold, published 7 February 2026 to 29 July 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.

این کل قضیه رسم مثلث بود نکته مثبت الگوریتمی که توضیح دادم اینه که نیاز نیست چک کنیم یه پیکسل داخل مثلث هست یا نه چون همیشه محدوده پیکسل‌های داخل مثلث رو با شیب خط بین رئوس میدونیم. - بطور خلاصه از یه راس که بالاترین یا پایین راس مثلث باشه شروع میکنیم - محدوده کمینه و بیشینه مختصات x رو برابر مولفه x اون راس انتخابی میذاریم - نسبت تغییرات x به تغییرات y رو برای دو راس دیگه محاسبه میکنیم (dx/dy) - هربار که به سمت را

با این تغییرات، حتی اگر مثلث ما به این دو حالت هم باشه بازم الگوریتم درست کار میکنه و دیگه محدود به این نیست که حتما یکی از رئوس باید بالاتر از دوتای دیگه باشه :)

ولی این الگوریتم دوتا باگ داره: اولی اینه که من فرض کردم حتما یه راس از مثلث بالای دو راس دیگه هست. دومی هم اینه که اگر به راس وسط برسیم شیب یکی از خطوط عوض میشه. پس ما میایم مثلثمون رو از راس وسط تبدیل به ۲تا مثلث میکنیم. یکی کف و اون یکی سقف صاف داره. با این کار میدونیم که شیب خط منتهی به رئوس مثلث همیشه ثابته حالا تمام انواع مثلث رو میتونیم رسم کنیم یکبار از بالا شروع میکنیم و تا راس وسطی ادامه میدیم یکبار هم

به همین راحتی ما میتونیم از مختصات راس بالایی شروع کنیم و با پایین اومدن و کم کردن y، بازه عددی که x داخلش قرار میگیره رو میتونیم پیدا کنیم :))) مقدار اولیه x min و x max برابر مقدار x راس بالایی خواهد بود هربار که میایم پایین به اندازه dx/dy بازه رو تغییر میدیم مقدار x min اینجا توی این شکل با dx/dy راس وسطی جمع میشه مقدار x max هم با dx/dy راس پایینی جمع میشه اینجوری نیاز نیست حتی بررسی کنیم پیکسل داخل مثلث هست

برای اینکه ببینیم یه نقطه داخل یه مثلث هست یا نه لازم نیست پیکسل‌ها رو با روش‌های عجیب بررسی کنیم + اینجا فرض میکنیم مختصات رو به حالت Screen ترجمه کردیم. ما مختصات رئوس مثلث رو داریم پس در نتیجه میتونیم با محاسبه کردن شیب خط بین اون‌ها، ببینیم اگر y رو به اندازه dy تغییر بدیم، مقدار x چقدر تغییر میکنه. چون با اسکن کردن هر خط از پیکسل‌ها ما داریم از بالا به پایین میایم. این یعنی مقدار y هربار یک پیکسل کم میشه پس من

بعدش میتونیم شروع کنیم و هر سطر از پیکسل ها رو بررسی کنیم و ببینیم که داخل مثلث هست یا نه اگر داخل مثلث بود اون پیکسل رنگ میشه ولی مشکل اول اینه که چجوری تشخیص بدیم پیکسل داخل مثلث هست یا نه برای این کار یادتون باشه که ما مرکز هر پیکسل رو نماینده اون پیکسل درنظر میگیریم مشکل دوم اینه که اسکن کردن تمام پیکسل‌ها خیلی کنده و نیاز نیست لزوما این کارو بکنیم یه راه بهتر برای این کار هست :) @hxnotes

حالا برای رسم مثلث اول فرض میکنیم تمام رئوس مختصاتشون بصورت Normalized هست بعدش باید اونارو با ترتیب مقدار مولفه y مرتب کنیم چون این کار بهمون کمک میکنه بدونیم کدوم راس بالا، وسط و پایین مثلثه @hxnotes

چرا این فرمول‌ها کار میکنن؟ چون ما میخوایم بازه منفی یک تا مثبت یک رو به بازه صفر تا طول/عرض پنجره تبدیل کنیم اینجا مرحله به مرحله برای تبدیل طول نوشتم که چجوری این اتفاقات میفته مقدار y باید یکبار از عدد یک کم بشه چون توی مختصات صفحه نمایش وقتی y پایین میره درواقع داره بیشتر میشه (برعکس مختصات عادی) @hxnotes

در ابتدا برای اینکه این کارو انجام بدیم باید با مختصات صفحه آشنا باشیم ما یه سیستم مختصات Normalized داریم که x و y توی اون بین منفی یک و مثبت یک هستن. خوبی این سیستم اینه که مستقل از ابعاد صفحه نمایش یا پنجره برنامه ما کار میکنه اما وقتی میخوایم پیکسل ها رو رسم کنیم باید اون مختصات رو ترجمه کنیم به مختصات صفحه نمایش یا Screen برای این کار هم ۲تا فرمول داریم که توی عکس نوشتم حرف W طول صفحه (محور x) حرف H عرض صفحه

چند روز قبل یه Rasterizer نوشتم که میتونه راس های یه مثلث رو بگیره و بعد اونارو به تصاویر قابل نمایش رندر کنه درواقع اینجا میخوایم کاری که کارت گرافیک برامون انجام میده رو توی نرم‌افزار پیاده سازی کنیم که بهش software rendering هم میگن یعنی با استفاده از CPU فریم ها رو ترسیم میکنیم و نمایش میدیم @hxnotes

Showing the 12 most recent of 17 posts we hold for @hxnotes. 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.

Citation-graph rank

Citation-graph rank — 330,042 of 1,151,006entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.

Forward network

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

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.
