2 measurements spanning 3 days. 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 50–52 and does not start at zero.

Engagement

20 posts held, back to 11 December 2024the 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 24 February 2026. An engagement rate over an empty window would be a number about nothing.

Lifetime counters from Telegram’s own channel header, read 10 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

История с MySQL продолжает развиваться. Вадим Ткаченко (Percona) призвал обратиться к Oracle c открытым письмом. Популярность MySQL снижается. PostgreSQL стал выбором по умолчанию для новых проектов. MySQL находится под реальной угрозой стать неактуальным, если мы ничего с этим не сделаем. Тем не менее, существующая база установок огромна – MySQL по-прежнему обеспечивает работу значительной части интернета. Осен

🚨 Исправлена давняя проблема MySQL! В выпущенном 9.6 внешние ключи стали «видимыми» и полноправными. MySQL 9.6, релиз которого состоялся в конце января, устраняет давний архитектурный недостаток: каскадные операции внешних ключей ( ON DELETE/UPDATE CASCADE ) теперь выполняются на уровне SQL-движка, а не скрытно внутри InnoDB. Чем это было плохо раньше? Было две ключевые проблемы: 🔴 Скрытые изменения: Каскадные удал

Не только постгрес Если вы следите за эко-системой MySQL (СУБД, по моему мнению, не менее удобной и производительной, чем PostgreSQL, хотя и на С++ 😄) — обратите внимание, во-первых, на прекрасный блог MyDB, а во-вторых на два интересных поста: — о VillageSQL: это свежайший форк MySQL, на днях вышли из stealth-режима, за проектом стоят топовые сотрудники MySQL и Google, проект привлек $35 млн. — о TideDB: новый иг

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

Forward network

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.

Mentions

Names

Channels on the register whose handles appear in this channel's posts.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
