20 posts held, back to 19 November 2024 — 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 20 November 2024. An engagement rate over an empty window would be a number about nothing.
3 reactions across 2 posts, in 2 distinct kinds. The most used accounts for 66.7% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 2 | 66.7% | |
| ❤ | 1 | 33.3% |
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 2 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 3reactions 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 19 November 2024 to 20 November 2024, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
Designer cells 'reboot' immune system in 3 different autoimmune diseases In an early-stage clinical trial, scientists explored the potential of designer immune cells to "reboot" the immune systems of patients with autoimmune diseases using a form of CAR T cell therapy, traditionally used for blood cancers like leukemia. This innovative approach involved a single infusion of genetically modified T cells to eliminate r…

How human brains got so big: cells learned to handle stress that comes with size In this intriguing exploration of human brain evolution, researchers have uncovered how our disproportionately large brains manage the stress associated with their size. By studying dopamine-producing neurons in humans and comparing them with those in other primates, scientists found that human neurons express more genes that enhance ant…

Enormous cache of rare earth elements hidden inside coal ash waste Recent research from The University of Texas at Austin reveals that coal ash, a byproduct of burned coal, contains significant quantities of rare earth elements (REEs), potentially bolstering the U.S. supply without new mining. This "trash to treasure" approach could reduce environmental impacts while addressing the U.S.'s reliance on REE imports, pri…
Why Smart C Coders Love Lua Embedded systems have traditionally relied on C and C++ for their performance and control. However, with the rise of IoT and edge devices, developers are increasingly turning to Lua, especially when paired with frameworks like Xedge. Lua offers a higher-level approach, simplifying development and reducing time-to-market. Unlike C, Lua is garbage-collected, easing memory management and mini…
PaCMAP: Large-Scale Dimension Reduction with Both Global and Local Structure [pdf](https://news.ycombinator.com/item?id=42189253) In this paper, we explore the intricacies of dimension reduction (DR) techniques like t-SNE, UMAP, and TriMap, which are pivotal for data visualization. These methods often face a trade-off between preserving global and local structures. Our research aims to understand the critical aspects…

Elasticsearch Was Great, but Vector Databases Are the Future The article from The New Stack argues that while Elasticsearch has been a staple for keyword-based search, the future lies in vector databases, which excel in semantic search. As AI advances, semantic search, which understands the meaning behind queries, is becoming crucial. Vector databases, like Milvus, offer a hybrid approach by combining semantic and ke…

Showing the 12 most recent of 20 posts we hold for @hn_summary. 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.
This handle named by sources this register does not control and did not measure — each shown exactly as found, attributed by name, dated to when it was read.
Hacker News
This handle was named once in a Hacker News comment or story, via the public Algolia search API. HN comment and story text has no confirmed reuse licence, so nothing quoted from either is reproduced here — only that a mention exists, when, and by whom, with a link to read it at the source.
