Topic

Technology — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 29 September 2026 and assigned it the closest of 31 fixed categories, at 99% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and why it has no browse page of its own yet.

4 measurements spanning 34 days, net +3. 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 38–41 and does not start at zero.

Engagement

20 posts held, back to 25 January 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 1 page 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 20 posts for this entry, the most recent from 22 May 2026. An engagement rate over an empty window would be a number about nothing.

Reaction mix

31 reactions across 12 posts, in 9 distinct kinds. The most used accounts for 38.7% of them.

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 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 31 reactions 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 25 January 2025 to 22 May 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.

I just read an article by legendary Daniel Lemire titled "Only 17% of all 64-bit Integers are products of two 32-bit integers", and here's what was new for me: I'd never really thought about how limited the space of multiplication results is. Granted, roughly a sixth of all 64-bit values is actually quite a lot - but it's good to be aware that you can only get so many distinct results out of two fixed-size factors. …

I started the "Claude 101" course made by Anthropic Academy. Here are some chaotic notes along the way through the first 4 chapters combined under the "Meet Claude" title. Some of them come from my methodology and tutoring experience. Chapter "Your first conversation with Claude" implies - never says that, but gives a feeling - that memory feature is always on: "Memory automatically saves key context from your conve…

PEP 830 - in Python 3.15, exception objects will include nanosecond‑precision timestamps. The feature carries minimal risk and negligible overhead, and it remains disabled by default.

Python 3: the story of hash and equality dunder methods I). Python 3.0: a set of previously existed data model rules were enforced to define how objects should be hashed (1). The key idea is that if objects' values are equal, their hashes should also be equal. The reverse is not required - hash collisions are allowed. By default both hash and equality dunders were inherited from the object class, and the default has…

Python 3.15 has a lot of cool features planned on October 2026, and one of them is the ability to use lazy imports. Lazy import allows to defer the loading and execution of a module until the first time the imported name is used. It can reduce startup time and memory usage, especially for applications with huge dependency graphs. lazy import pandas as pd lazy from numpy import inf The idea was first rejected throu…

From time to time I dive into small fun projects. For example, a Python (PyGame + PyGbag) mini-game on cave exploration, playable on PC in browser. Source code could be found here. Features: - WASD motion controls, long-press enabled - ESC to quit - Fog of war hides the map - Player spreads light in a small radius - Stepping into a new cave increases map scale - Caves are auto-generated

I’m happy to share that I’ve obtained a new certification: Finished Computer Science course from CS50! I nailed harder versions of every project quite fast. Though I really struggled with the idea of the final project and procrastinated for several months. But as my recorder hobby grew - I finally got inspired! As my final project I made a helper tool for me to withstand a daily challenge of playing melodies: FluTab…

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

Republished by

Channels on the register that have forwarded this channel's posts into their own feed.

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

Named by 1 registered channel — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.

Named by

Channels on the register whose posts name this channel's handle.

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.
