20 posts held, back to 10 June 2022 — 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 pageof 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 7 September 2023. An engagement rate over an empty window would be a number about nothing.
131 reactions across 19 posts, in 2 distinct kinds. The most used accounts for 99.2% of them.
| Reaction | Count | Share | Share, drawn |

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 19 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 131reactions 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 10 June 2022 to 7 September 2023, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

-- Implementing Condition Variables with Semaphores The paper discusses the implementation in C# but it is a straightforward translation to C/C++. The reason I shared this paper is to show the thought process and the things people have to keep in mind when designing a solution for concurrency/parallel programming primitives. All the kernels provide a semaphore as a primitive that can be used to build all the nece…

The shared_ptr equivalent is similarly simple: just swap out the std::unique_ptr<T, Deletion> return value with std::shared_ptr<T>, and change the name to indicate a shared resource: template < typename T, typename Deletion, typename Acquisition, typename...Args> std::shared_ptr<T> make_c_shared_handler( Acquisition acquisition, Deletion deletion, Args&&...args){ return {acquisiti…

How can I use RAII to manage resources programmed using a C-style API? There is an easy way to use RAII to manage resources from a C-style interface: the standard library's smart pointers, which come in two flavors: std::unique_ptr for resources with a single owner and the team of std::shared_ptr and std::weak_ptr for shared resources. If you're having trouble deciding which your resource is, this FAQ should help yo…

in a larger program, it would not be.) Of course, if the only outputs you want to see are 0 0 or 37 17, you can just wrap a mutex around the original code. But if you have read this far, I bet you already know how that works, and this answer is already longer than I intended :-). So, bottom line. Mutexes are great, and C++11 standardizes them. But sometimes for performance reasons you want lower-level primitives (e…

What is Standard Memory Model that was introduced in C++11 and how does it help? The C++ specification does not make reference to any particular compiler, operating system, or CPU. It makes reference to an abstract machine that is a generalization of actual systems. In the Language Lawyer world, the job of the programmer is to write code for the abstract machine; the job of the compiler is to actualize that code on …

Linker errors are so hard to understand because of the mangled names. Is there a way to see the actual function names instead of these weird mangled names? When you compile and link your code, you can pass an additional option to the linker specifying whether any error output from the linker should show demangled names or mangled names. Consider the following code: void foo(); void foo(int); int main() { foo()…

Showing the 12 most recent of 20 posts we hold for @cpp20programming. 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.
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 19 August 2026 — this entry's latest reading, not the date you are reading this.
