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 28 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.

20 posts held, back to 24 August 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 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 21 April 2025. An engagement rate over an empty window would be a number about nothing.
27 reactions across 13 posts, in 3 distinct kinds. The most used accounts for 48.1% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 13 | 48.1% | |
| 👍 | 9 | 33.3% | |
| 🔥 | 5 | 18.5% |
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 13 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 27 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 24 August 2024 to 21 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.
Simple Modularization setup for a New App This article introduces a simple modularization setup for new iOS apps using Swift Package Manager and local packages. It explains the benefits of modularization, outlines a basic project structure with Core, Domain, and Presentation layers, and offers practical tips for managing dependencies and scaling the approach as the app grows.

Software Engineer ≠ Developer 🔍 Software Engineer = Problem Solver 💡 Here’s the truth no one tells you when you start writing code: Great engineers don’t just jump into coding. They start by solving the problem, without writing a single line. Why? Because code is a liability. Every line you write = something you’ll maintain, debug, and defend in production later. The best engineers I’ve worked with all do the sam…

📝 #solution #3 Explanation: - The formula n * (n + 1) / 2 gives the sum of numbers from 0 to n. - nums.reduce(0, +) calculates the sum of the elements in the array. - The missing number is simply the difference between the expected sum and the actual sum. * the array should contain n distinct numbers in the range [0, n]. Otherwise, the algorithm won't work as expected because it's designed for a specific kind of in…

📝 #challenge #3: easy. Find the Missing Number 🔍 Problem Statement: Given an array nums containing n distinct numbers in the range [0, n], find the one number that is missing from the array. Your solution should run in O(n) time and use O(1) extra space. 💡 Example: let nums = [3, 0, 1] let result = missingNumber(nums) print(result) // Output: 2 🔧 Function Signature: func missingNumber(_ nums: [Int]) -> Int { …
📝 #solution #2 This solution runs in O(n) time and uses O(1) extra space by modifying the array in place. It works by using the indices of the array to mark the presence of each number. When we encounter a number that has already been marked negative, we know it's a duplicate. @software_efficiency
📝 #challenge N2: #medium level. Find All Duplicates in an Array 🔍 Problem Statement: Given an integer array nums of length n where all integers are in the range [1, n], find all the integers that appear twice in the array. The solution must run in O(n) time and use only constant extra space. 💡 Example: let input = [4,3,2,7,8,2,3,1] let result = findDuplicates(input) print(result) // Output: [2, 3] 🔧 Function Sign…

📝 #solution N1 Explanation: - Boyer-Moore Voting Algorithm works by maintaining a candidate for the majority element and a counter. - We iterate through the array: -- If the count is zero, we set the current element as the candidate. -- For each element, we either increase the count (if it matches the candidate) or decrease it (if it doesn't). - By the end of the iteration, the candidate will be the majority element…
📝 #challenge N1: #medium level. Find the Majority Element. 🔍 Problem Statement: Given an array of integers, find the majority element. The majority element is the one that appears more than half the time in the array. You may assume that the array is non-empty and that the majority element always exists in the array. 💡 Example: let input = [3, 2, 3] let result = findMajorityElement(input) print(result) // Output: …

Insight: "Consistent naming conventions are essential for clean code. Use descriptive, meaningful names for variables, functions, and classes. Good names should reveal intent, making your code easier to understand without requiring extensive comments." - Consistency: Stick to a consistent pattern throughout your codebase to make it easier for others (and yourself) to understand and maintain.

Showing the 12 most recent of 20 posts we hold for @software_efficiency. 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.
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 30 August 2026 — this entry's latest reading, not the date you are reading this.
