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 14 September 2026 and assigned it the closest of 31 fixed categories, at 96% 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.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views — note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

💡 Detailed Explanation: The 'kubectl rollout undo' command automatically reverts a deployment to its previous revision, which is the standard way to handle failed updates.
A production web server is down. You need to quickly roll back a broken container image deployment. Which Kubernetes command is best?

💡 Detailed Explanation: Multi-stage builds allow you to discard build tools and caches, significantly reducing the final image size and improving deployment speed.
A CI/CD pipeline fails because a container image exceeds the registry size limit. What is the most efficient DevOps practice to fix this?
- Increase the registry storage quota4%

💡 Detailed Explanation: OOMKilled indicates the container exceeded its assigned memory limit. Updating the resource manifest ensures the container has sufficient memory.
A production Kubernetes deployment is crashing due to OOMKilled errors. What is the most effective way to address this?
- Increase the pod replica count to distribute the load.28%
- Adjust resource requests and limits in the deployment spec.61%
- Restart all nodes in the cluster to clear memory cache.6%
- Disable the liveness probe to prevent container restarts.6%

💡 Detailed Explanation: Multi-stage builds allow you to copy only the necessary artifacts from a build image into a minimal runtime image, significantly reducing the final footprint.
A CI/CD pipeline fails because a container image is too large. What is the most effective way to optimize the image size?
- Increase the Kubernetes worker node instance size.5%
- Use multi-stage builds to discard build-time dependencies.91%
- Switch the base image to a full-featured Linux distribution.5%
- Enable compression on the container registry storage.0%

💡 Detailed Explanation: The OOMKilled status code indicates the process was terminated by the OOM killer because it exceeded the assigned memory limit.
A production container restarts constantly with 'OOMKilled'. What is the cause?
- The application code has a syntax error.0%
- The container exceeded its memory limit.91%
- The CPU usage reached 100%.9%
- The container image has an invalid tag.0%

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

Percentages only — there are no per-option vote counts here, because Telegram publishes none. The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.
The shares need not add up to 100. Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.
Read from the 20 most recent posts we hold, published 26 August 2026 to 5 September 2026. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.
Appears in Telegram’s recommendations for other channels
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.
