18 posts held, back to 24 September 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 7 pages 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 18 posts for this entry, the most recent from 6 July 2026. An engagement rate over an empty window would be a number about nothing.
29 reactions across 12 posts, in 4 distinct kinds. The most used accounts for 82.8% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 24 | 82.8% | |
| 👏 | 2 | 6.90% | |
| 🔥 | 2 | 6.90% | |

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 12 of the 18 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 29 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 18 most recent posts we hold, published 24 September 2025 to 6 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.

🐧 Quick Linux tip: Got log files compressed as .gz? You don’t need to extract them to read or search through the content. Use the 'z' tools directly: • zcat - view the file • zless - scroll through it • zgrep - search inside it • zegrep - search with extended regex • zfgrep - search for fixed strings • zcmp/zdiff - compare files These commands let you inspect compressed logs without unpacking them first, perfect …
🛜 7 Layers of the OSI Model vs TCP/IP Model Visual Guide: The OSI model (Open Systems Interconnection) is a seven-layer theoretical stack that can be used to explain how a network works. The concept was established to standardize networks in a way that permitted multi-vendor systems; before this, you could only have a single-vendor network because the devices could not communicate with one other.

🐧 Quick Linux tip: The diff command is a useful tool for finding differences between files in the Linux terminal. However, icdiff offers an even better side-by-side comparison with colorized output. $ icdiff config-dev.ini config-prod.ini The output will display both files side-by-side with any differences highlighted in red and green, making it easy to spot the difference.

Showing the 12 most recent of 18 posts we hold for @coding_hacking_college_courses. 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.
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 8 September 2026 — this entry's latest reading, not the date you are reading this.
