4 measurements spanning 8 days, net -8. 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 2,966–2,976 and does not start at zero.

Engagement

20 posts held, back to 2 April 2025the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 3 pagesof 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 20 posts for this entry, the most recent from 9 June 2025. An engagement rate over an empty window would be a number about nothing.

Reaction mix

19 reactions across 7 posts, in 3 distinct kinds. The most used accounts for 89.5% 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 9 of the 20 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 19reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 2 April 2025 to 9 June 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.

How to Create a Custom Exception in Python In my journey as a Python developer, I've found that creating custom exceptions can significantly enhance error handling in your applications. Here are the steps to create your own exception class: 1. Define your custom exception: Inherit from the built-in Exception class. class MyCustomError(Exception): pass 2. Raise your exception: Use raise to trigger yo

Understanding the Observer Design Pattern in Java The Observer design pattern is a powerful tool in software design that allows for a one-to-many dependency between objects. When one object (the subject) changes state, all its dependents (the observers) are notified and updated automatically. Here’s a quick breakdown: 🔹 Key Components: - Subject: Maintains a list of observers and notifies them of state changes. - O

Understanding the Basics of Python Generators Generators are a fundamental aspect of Python, allowing us to create iterators in a memory-efficient way. Here’s a quick overview of their benefits and usage: - Memory efficiency: Generators yield one item at a time, so you don’t need to store the whole iterable in memory. - Lazy evaluation: Values are produced only when requested, which can lead to performance improvem

Showing the 12 most recent of 20 posts we hold for @topJavaQuizQuestions. 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.
