16 posts held, back to 27 September 2023 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 9 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 16 posts for this entry, the most recent from 22 April 2025. An engagement rate over an empty window would be a number about nothing.
Measured directly from 1 video with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.
371 reactions across 15 posts, in 3 distinct kinds. The most used accounts for 70.9% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 263 | 70.9% | |
| ❤ | 65 | 17.5% | |
| 🙏 | 43 | 11.6% |
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 15 of the 16 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 371reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 16 most recent posts we hold, published 27 September 2023 to 22 April 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.

最早的时候,谷歌搜索的网址是挂在斯坦福大学的网站上的。谷歌的创始人拉里·佩奇和谢尔盖·布林在1997年发表的论文中说: “我们认为由广告商来赞助搜索引擎,将会使得搜索引擎的返回结果受到广告商的需求的影响,从而偏离真正的用户需求。广告越多,搜索引擎的搜索质量就越差。正因为广告商的存在会极大影响搜索引擎的质量,我们相信我们的社会需要一个搜索质量优秀、排序公正透明、由学术界监督的搜索引擎。” source

ubuntu 是来源于非洲的一整套哲学价值体系,这套价值体系的核心在于人和人之间的联系 —— 有你才有我。ubuntu 这个词的直译是“善待别人”。 而 Ubuntu 操作系统的团队选取这个名字,是因为这个团队希望将 ubuntu 的精神带到电脑和软件的赛博世界里。 注:Ubuntu 是一款基于 Linux 的操作系统。Ubuntu 的读音是,“乌邦兔”。 source

技术虽然是客观的、中立的,但使用技术的人是社会性的、政治性的。所以那个假设,即“技术(生产力)高度发达,人类就会实现富强、民主、平等、自由”,是不合实际的幻觉。人类的共同进步,靠的必须是政治本身的进步。这些不是经济和技术发达所能自动带来的,需要我们专门去努力争取。 回到“AI抢饭碗”这个话题,其实AI不是天然就会抢人的饭碗。社会公平主要不是生产问题,而是分配问题。AI“抢了”人类生产的机会,但并没有也不会抢人类分配的权利。如果一个社会,分配权力是掌握在老百姓手里,那么,没有人会拒绝所有的农业、工业、服务业全都由AI来承担,这样人可以免于高危高温高寒工作,免于风餐露宿,免于把生命耗费在低水平重复的流水线……省下来的时间和精力用于运动、文学、艺术、哲学、陪伴家人、旅游看风景……这不是好事吗?问题出在哪?出在我们的社会,分配权不在普通人手里,集中在极少数权贵手里。于是,分配权紧紧地依附于生产权。出于对生产的忌惮,权贵还会让渡一部分利…

1968年,琳·康维性别转换,随即被IBM解雇,家人也与她断绝了关系。 离开IBM后,康维开始钻研微型芯片技术,成为了该领域的先驱。后来的智能手机的发明,就是基于这项技术的。 康维一生都在为跨性别社群争取平等的权利。她的发声鼓舞了各界各地的人站出来,一同组建跨性别社群。 2024年6月9日,琳·康维去世,享年86岁。康维在多个领域作出了开创性的贡献,是一位广受爱戴的传奇般的人物。我们永远怀念她。 琳·康维(1938-2024)。感谢你为这个世界做的一切。 source

目前,有一半网页用户使用广告屏蔽器,但却几乎没有手机用户能成功屏蔽广告,为什么?这是因为在手机上屏蔽广告,需要先移除手机应用的加密保护才能在该APP在加载广告时对广告进行屏蔽,而根据著作权法,移除应用程序的加密是一项重大罪行。制作了各种苹果手机的越狱软件,使用户可以在苹果手机里自行安装应用程序的杰·弗里曼说:这是那些公司的商业模式,利用完全不合理的罪名,给心怀用户的程序员泼名为“犯罪”的脏水。 正是因为在手机上可以为所欲为地增加广告,而不用担心用户因此屏蔽广告。大公司的董事会开会的时候,可能有人会提出,我们要不要为了2%的盈利,让我们的广告更恶心更招人厌怎么样?大家觉得没有问题,全票通过。因为这些人知道,即使用户看了很糟心的广告,然后在网上搜索“手机应用里该如何屏蔽广告”,TA们也只能得到唯一的答案 —— 没法屏蔽。这也就是为什么现在各大公司都希望你用它们的手机应用,而不是网页版。 我们完全有技术做手机应用上的广告屏蔽,也完…

Showing the 12 most recent of 16 posts we hold for @useless_project_ideas. 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.

Channels on the register whose posts this channel has forwarded.
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.
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 14 August 2026 — this entry's latest reading, not the date you are reading this.
