YINI Specification RC 6 is now released The YINI configuration format has reached Specification Release Candidate 6 . YINI is a configuration format designed to feel familiar if you like INI-style files, but designed to bring more explicit structure, clarity, useful data types, and predictable parsing rules to real-world configuration needs.. The short version: @yini ^ App name = "Example" version = "1.0.0" debug = false ^^ Server host = "127.0.0.1" port = 8080 ^^ Features enabled = [ "auth", "logging", "metrics", ] YINI tries to sit somewhere between classic INI, JSON, TOML, and YAML: More structured than traditional INI. Less punctuation-heavy than JSON. Indentation-insensitive unlike YAML. Explicit about parsing rules and validation behavior. RC 6 is an important release because it tightens several parts of the language and moves the format closer to a stable 1.0 specification. What changed in RC 6? RC 6 includes a number of syntax and behavior updates. The main theme is the same as before: Make the format clear for humans, but deterministic for parsers. Here are some of the notable updates. Clearer section markers YINI uses section markers to define structure. ^ App name = "MyApp" ^^ Server host = "localhost" ^^^ TLS enabled = true The number of section markers defines the nesting level. This keeps hierarchy visible without relying on indentation. The primary section marker is: ^ YINI also supports alternative section markers, but ^ remains the recommended default for most files and examples. Strict and lenient mode behavior is more clearly defined YINI has two parsing modes: Lenient mode — practical, forgiving, and intended as the default. Strict mode — validation-focused and intended for stricter tooling, CI checks, and production-sensitive configuration. A file can declare its intended mode: @yini strict or: @yini lenient RC 6 clarifies how these declarations should behave when the file is parsed in a different mode. The goal is to avoid silent surprises. If

Every developer who has ever muttered "there is a bug in this" is repeating a word with a surprisingly literal origin. On September 9, 1947, the operators of the Harvard Mark II, an early electromechanical computer, traced a malfunction to its source and found something they did not expect: a moth wedged inside Relay #70. They removed the insect, taped it into the operations logbook, and wrote a now-famous line beside it: "First actual case of bug being found." That page, moth and all, survives today in the collection of the Smithsonian's National Museum of American History. It is one of the best-loved stories in computing, and like most good stories it is a little more complicated than the popular version. Worth getting right, because the discipline it gave us is the same one behind every connected device we build. What actually happened in 1947 The Mark II was a room-sized machine built from relays, switches, and thousands of moving parts. When a moth flew into one of those relays, it physically interfered with the contacts and caused a fault. The technicians who found it had a sense of humor: calling it the "first actual case of bug being found" was a joke precisely because engineers had already been using "bug" for years to describe mysterious faults in machinery. Thomas Edison used the term in his notebooks back in the 1870s. So the 1947 moth did not invent the word "bug." What it did was give the term a perfect, photographable origin story, and it cemented the companion word that really matters: debugging. The act of removing that moth was, quite literally, de-bugging the computer. The Grace Hopper connection The story is almost always told with Grace Hopper at its center, and that deserves a small correction. Hopper, a pioneering computer scientist who later helped develop COBOL, was part of the Mark II team in 1947, but the evidence suggests she did not personally find the moth or write the logbook entry. What she did do was tell the story, brilliantly and o

Modern collaboration needs more than documents and chat messages. Teams need a shared visual space where ideas can be created, organized, and refined together in real time. That's why I built SyncCanvas — an AI-powered collaborative whiteboard that combines real-time multiplayer collaboration, infinite canvas drawing, and AI-assisted brainstorming into one modern workspace. The Problem Most collaboration tools focus on only one aspect of teamwork. Some are great for drawing. Others are excellent for documentation. AI tools often live in separate windows, disconnected from the creative workflow. I wanted a platform where teams could brainstorm visually while AI actively helped generate and organize ideas directly on the canvas. Introducing SyncCanvas SyncCanvas is an infinite multiplayer whiteboard designed for students, developers, teams, and creators. Key features include: Real-time collaboration with live synchronization Infinite canvas with pan and zoom Drawing tools, shapes, text, and sticky notes AI-powered content generation using Gemini Private room sharing Guest mode access PNG export support WiFi Rooms for local collaboration Real-Time Collaboration Collaboration is at the heart of SyncCanvas. Using Yjs and WebSockets, multiple users can work on the same board simultaneously while seeing updates instantly. Users can: View live cursors Track online participants Join private rooms using secure room codes Collaborate anonymously through guest mode This creates a seamless experience similar to working together in the same room. Infinite Canvas Experience The whiteboard is designed to be limitless. Users can: Draw freehand sketches Create rectangles and circles Add text elements Organize ideas with sticky notes Move freely across an infinite workspace Export workspaces as images The canvas is powered by Fabric.js, providing smooth rendering and flexibility for future enhancements. AI-Powered Brainstorming One of the most exciting features is the integration of G

The main idea of a Carousel isn't just about moving a bunch of elements from left to right because there must be a smoothly infinite movement, this can be done by duplicating the element, but wouldn't it be a waste of time and resources to do so. So the best solution would be rather than moving the whole element, we just move each element on a time based manner, all elements will have the animation but each element will have a unique (incremented) index, by which we will delay its start, and if we made this delay negative, we will have a smooth movement without any lagging adding a will-change will make a separate compositing layer to make the animation run on gpu rather than cpu below is a demo by which, you can understand the effect You can reach me (if you had any problems with the effect): X / twitter "where I post a lot!"

A few months ago I was about to buy a flight. The page showed "Only 2 seats left at this price" in red letters. I hesitated, then refreshed the page out of curiosity. The counter said "Only 2 seats left" again. Same number. It had been resetting on every page load the whole time. That's when I started cataloguing every trick I'd seen on shopping sites and built a Chrome extension that flags them automatically, in real time, on any page. This isn't just my opinion — it's documented research In 2019, Princeton and University of Chicago researchers scraped 11,000 shopping sites and found dark patterns on more than 1,250 of them. The FTC has since fined several companies specifically for fake countdown timers and pre-checked subscription boxes. This isn't a grey area anymore — it's a known, studied, and increasingly regulated practice. The extension targets four categories that account for most of what's out there. The four patterns Fake urgency. Countdown timers that reset, "X people are viewing this" badges that never change, "only N left in stock" that's been static for a week. Trap checkboxes. A checkbox for "Yes, sign me up for the newsletter" that's pre-checked and styled to blend into the page so you don't notice it. Confirmshaming. The decline button reads "No thanks, I don't want to save money" instead of just "No thanks." Psychological pricing. Prices ending in .99 or .95 designed to register as a lower price bracket than they are. Why no AI this time My phishing detector used Claude because language and intent are genuinely ambiguous — you need a model that understands context. Dark patterns are different. They're structural. A countdown timer either resets on reload or it doesn't. A checkbox is either pre-checked or it isn't. That's a DOM query, not a judgment call. So this one runs entirely on regex and DOM inspection. No API calls, no latency, no cost per scan, works offline. Sometimes the boring solution is the correct one. Detecting the urgency pattern T

Your runbooks are out of date. I don't know your team, but I'd bet money on it. Most teams write runbooks once, in a panic after an outage, and then never touch them again until the next outage proves them wrong. How runbooks rot Steps reference deprecated tools. The grafana dashboard moved, the CLI command was renamed, the bastion host got retired. Nobody updated the runbook because nobody re-ran it during the calm months. The team that owned the system left. Three of the five engineers who wrote it are gone. The remaining two haven't actually run the runbook in 18 months because the outage type it covers stopped happening. Half-truths from the start. The original author skipped the obvious steps (because they were obvious to them) and the new on-call engineer can't reproduce the recovery. The result: at 2 AM during the actual incident, the runbook sends you down a dead end. Now you're improvising under stress. What working runbooks have in common I've seen exactly two patterns work: 1. Runbooks live with the code. Put them in the repo of the system they document. When the code changes, the runbook PR is part of the same review. Out-of-repo wikis die first because the cognitive distance is too great. 2. Runbooks are reviewed by people who weren't there. Have a junior engineer run through the runbook quarterly on a non-incident day. Every place they get stuck is a real bug in the document. Fix it then. The author will be too close to see the gaps. The three sections that matter A useful runbook has exactly three sections: Symptom : how do I know this is the right runbook? Concrete signals, with example screenshots if visual. First 5 minutes : what to do RIGHT NOW to stop the bleed. Not the root cause investigation, just the triage actions. Investigation : where to look, what queries to run, what to escalate. That's it. Anything else (architecture diagrams, history, philosophy) goes in a separate doc that the runbook links to. The cultural part The hardest part isn't

Two monitoring approaches answer two different questions. Synthetic monitoring answers "would the checkout flow work right now if someone tried it?" Real user monitoring answers "what did the checkout flow actually do for the 4,000 people who tried it today?" The first is a robot testing a path on a schedule; the second is instrumentation recording reality as it happens. Teams reach for one when they need the other, then conclude monitoring "doesn't work." The fix is understanding what each is structurally good at — and where each is blind. Synthetic monitoring: proactive, scripted, continuous Synthetic monitoring runs scripted checks against your application from the outside, on a fixed schedule. An HTTP check hits an endpoint and asserts on the response; a browser check drives a headless Chromium through a journey — log in, add to cart, pay — and asserts on what the user would see. The defining property is that it does not need real traffic. The check runs every 30 seconds whether or not anyone is using the app, from datacenters you choose, testing exactly the journeys you scripted. When a deploy breaks checkout at 3 AM, a synthetic check catches it at 3 AM — not at 9 AM when the first customer wakes up. Real user monitoring: passive, real, traffic-dependent RUM instruments your actual frontend with a JavaScript snippet that reports back what real visitors experience: page load times, Core Web Vitals (LCP, INP, CLS), JavaScript errors, the device and network and geography of every session. It is a recording of reality with perfect fidelity — these are real people, real conditions, real outcomes. The cost of that fidelity is that RUM is entirely traffic-dependent and entirely retrospective. It can only report on paths real users took, after they took them. A page nobody visited generates no RUM data. A broken deploy at 3 AM is invisible to RUM until a real user hits it and the error is recorded. The core difference, side by side Dimension Synthetic monitoring Real

Most synthetic monitoring setups fail in one of a few predictable ways. They monitor everything and alert on nothing useful. They assert on status code 200 and miss the empty response body. They run flaky browser checks that page someone at 2 AM for a problem that fixed itself by 2:01. Or they go stale — the checkout flow changed three months ago and the check has been failing-then-being-ignored ever since. These are not exotic failures. They are the default outcome of setting up synthetic monitoring without a discipline. Here is the discipline. 1. Monitor the journeys that cost money, not everything Every browser check costs compute and, more importantly, costs maintenance. A check on a path that does not matter is worse than no check — it generates noise that trains your team to ignore alerts. Rank your journeys by cost of silent failure and monitor the top of the list: Authentication — login, signup. The gate to everything else. The revenue path — checkout, upgrade, add payment method. The core product action — the one thing your product exists to do. Critical third-party handoffs — OAuth redirects, payment iframes, SSO. Leave static pages, read-only endpoints, and admin screens to cheaper uptime and API checks . A good rule: if a path breaking would not generate a support ticket or lose revenue, it does not need a browser check. 2. Assert on what the user sees, not just the status code The entire point of synthetic monitoring is catching the failure that a 200 OK hides. So your assertions have to go past the status code. // Weak: passes even when the page renders an error await page . goto ( " https://shop.example.com/checkout " ); expect ( page . url ()). toContain ( " /checkout " ); // Strong: asserts the user can actually complete the action await page . getByRole ( " button " , { name : " Pay now " }). click (); await expect ( page . getByText ( " Order confirmed " )). toBeVisible ({ timeout : 10000 , }); await expect ( page . getByTestId ( " order-number "

You already have Playwright tests. They run in CI on every pull request, they assert that login works and checkout completes, and then they stop — because CI only runs them against a branch, at merge time. The moment the code is in production, those tests go silent. A third-party script breaks checkout at 3 AM and your perfectly good test suite says nothing, because nothing triggered it. Playwright monitoring closes that gap: you take the same browser tests and run them on a schedule against production, turning your end-to-end suite into a synthetic monitoring system that watches real user journeys continuously. Prerequisites Node.js 18+ and an existing project ( npm install -D @playwright/test , then npx playwright install chromium ). A deployed production (or staging) URL to run checks against. A dedicated synthetic test account — never a real customer's credentials. A secret store for that account's credentials (GitHub Actions secrets, or your platform's equivalent). Never hard-code them. Step 1 — Write a check that asserts on what the user sees A monitor-grade check is not "did the page load." It is "could a user complete the thing they came to do." Assert on the outcome, with a generous timeout for real-world latency: import { test , expect } from " @playwright/test " ; test ( " checkout reaches confirmation " , async ({ page }) => { await page . goto ( " https://shop.example.com " ); await page . getByRole ( " button " , { name : " Add to cart " }). click (); await page . getByRole ( " link " , { name : " Checkout " }). click (); await page . getByLabel ( " Email " ). fill ( process . env . SYNTHETIC_EMAIL ! ); await page . getByLabel ( " Card number " ). fill ( " 4242424242424242 " ); await page . getByRole ( " button " , { name : " Pay now " }). click (); // The assertion a 200 OK can never make for you: await expect ( page . getByText ( " Order confirmed " )). toBeVisible ({ timeout : 15000 , }); }); Credentials come from process.env , not the source. The t

If you want to reproduce my current local Hermes Agent + Qwen3.6-27B setup, this is the shape I would start from. Target One local coding agent. One 24GB GPU. Long context. Tools enabled. Thinking enabled. No child agents fighting the main request. The goal is not peak tok/s on a short prompt. The goal is: can the same agent session keep working after hours of tool calls without losing prefix locality, timing out during prefill, or getting wrecked by auxiliary requests? Model This setup is intentionally text-only. I am not serving the multimodal GGUF variant here. The working configuration uses groxaxo/Qwen3.6-27B-GPTQ-Pro-4bit through vLLM with --language-model-only . That choice matters. On a 24GB RTX 3090, the text-only GPTQ-Marlin path gave the best balance I found between long context, prefix caching, stable agent behavior and usable decode speed. Vision should be handled by a separate service/model if needed. vLLM The useful shape: CUDA_VISIBLE_DEVICES = 0 vllm serve groxaxo/Qwen3.6-27B-GPTQ-Pro-4Bit \ --served-model-name qwen3.6-27b-gptq-pro-4bit \ --dtype float16 \ --quantization gptq_marlin \ --tensor-parallel-size 1 \ --max-model-len 131072 \ --max-num-seqs 1 \ --kv-cache-dtype fp8_e5m2 \ --enable-prefix-caching \ --reasoning-parser qwen3 \ --enable-auto-tool-choice \ --tool-call-parser qwen3_coder \ --gpu-memory-utilization 0.95 \ --max-cudagraph-capture-size 32 \ --language-model-only I used a recent vLLM nightly, not an old stable image ( 0.20.1rc1.dev16+g7a1eb8ac2 ). The two flags people will want to argue about: --max-num-seqs 1 --max-model-len 131072 I use max_num_seqs=1 deliberately. With an agent, parallelism is not free. Title generation, context compression, retries, browser checks, tool calls and side jobs can all steal KV/cache locality from the main request. On one 24GB GPU I prefer one useful request over two requests sabotaging each other. 131k context is tight, but workable here. If your service OOMs, reduce context before adding MTP or enf

I was debugging an internal project management application built with SvelteKit and a Rust API. Locally, navigation felt almost instant. On the VPS, opening the Tickets, Timeline, and OpenSpec docs pages felt noticeably slower. Clicking a ticket also took too long before the preview panel became useful. My first assumption was infrastructure: Maybe the VPS was underpowered. Maybe PostgreSQL queries were slow. Maybe the reverse proxy added latency. Maybe SvelteKit SSR was taking too long. The measurements pointed somewhere else. The Baseline I started with the feature list endpoint used by both Tickets and Timeline. For a project with 52 tickets: Metric Result API response time ~4 ms Response size 353,956 bytes Number of tickets 52 The API was not slow. But it was returning around 354 KB for a list of only 52 items. The SvelteKit route payload showed the same pattern: Route Data payload Tickets 349,857 bytes Timeline 354,731 bytes This explained why local testing was misleading. On localhost, transferring and parsing a few hundred kilobytes is easy to miss. Once the app runs behind a VPS, reverse proxy, TLS, and a real network connection, the payload becomes much more visible. What Was Inside the Payload? I broke down the feature response by field. The descriptions alone accounted for: 296,177 bytes That was more than 80% of the complete response. The list endpoint was returning something similar to this for every ticket: interface FeatureListItem { id : string ; title : string ; status : string ; priority : string ; storyPoints : number | null ; dueDate : string | null ; description : string | null ; checkoutCommand : string | null ; openSpecCommand : string | null ; } The problem was not that these fields were useless. They were useful on the ticket detail panel. They were not useful when rendering the initial list. Timeline was even more wasteful. It used ticket status, dates, dependencies, and assignees, but still downloaded every full Markdown description. The D

For security reasons, we consider "Target app", as the target we practiced on, and the real name won't be disclosed in this post. The target app, was a niche music streaming platform, available in web and mobile PWA, meaning the structure is same but access is easier for cross platform. The app worked in this way : You register using an account, 3rd party like google or via email After that you can use the app for free with a 3 day window (3 day trial) After the 3 day you gotta buy subscription to continue listening The flaw, existed in the first step, when you register using an email, no verification happens! You could enter any type of string@something.com , a random password and start your free trial. So what happens is that first I use string1@something.com , for 3 days. When the time runs out, I use string2@something.com for another 3 days. And since the app's trial and actual subscription don't have any difference, and the 3 day time window is the only limitation, the user with such knowledge from the app doesn't need to buy any subscriptions while such flaw exists! Mitigation : Apply email verification step after user input, so they have to use the received link to verify their address Blacklist "temporary email" service's address or IPs, so users won't generate any email to register after their trial has expired. This way, the registration process isn't too complex while keeps app from attackers avoiding a "For ever free" usage on the app.

Stop Fighting Scikit-Learn Pipelines: How Metadata Routing Fixes Sample Weights & Groups A couple of months ago, I stumbled upon this video by Vincent D. Warmerdam about metadata routing in scikit-learn. I'll be honest, I had no idea what "metadata routing" even meant, but Vincent's explanation completely changed how I think about building ML pipelines. The video showed me that one of the most frustrating problems in scikit-learn; passing sample weights and groups through complex pipelines finally had an elegant solution. It piqued my curiosity enough that I dove deep into the feature, tested it extensively, and honestly, I was surprised by how little coverage this gets in technical blogs and articles. So I figured, why not write about it myself and share what I learned? If you've ever struggled with imbalanced datasets, grouped cross-validation, or just wanted to pass custom information through your pipelines, this article is for you. Let's start from the very beginning. What is "Metadata" in Machine Learning? Let's start with a concrete example. You're building a credit card fraud detection model with this data: # Your training data X = transaction_features # Amount, merchant, time, location, etc. y = is_fraud # 0 = legitimate, 1 = fraud # But you also have additional information: sample_weights = [ 1.0 , 1.0 , 10.0 , 1.0 , ...] # Fraud transactions weighted 10x customer_ids = [ 101 , 102 , 101 , 103 , ...] # Which customer made each transaction Metadata is the "extra information" beyond your features (X) and labels (y): sample_weight : How important is each transaction? (Fraud = 10x more important) groups : Which customer does each transaction belong to? (For proper cross-validation) Custom metadata : Transaction timestamps, confidence scores, data quality flags, etc. Why Metadata Matters: The Credit Card Fraud Problem Imagine you're building a fraud detection system for a financial company. You have: Imbalanced data : 99% legitimate transactions, 1% fraudulent T

Imagine a user trying to upload a 100MB video or a high-resolution photo to your app. If you use the standard Rails file upload, that file travels from the user's browser to your Rails server, and then your server sends it to S3 or Google Cloud. This is a terrible way to do it. While that 100MB file is transferring, your Rails worker (Puma) is frozen. It can't handle other users. If three people upload large files at once, your whole app will stop responding. In 2026, the professional way to handle this is Direct Uploads . With Direct Uploads, the file goes directly from the user's browser to your cloud storage (S3, R2, etc.). Your Rails server only handles a tiny bit of metadata. It is faster for the user and much safer for your server. Here is how to set it up in Rails 8. STEP 1: Configure Your Storage First, make sure you aren't using the local disk for production. You need a cloud provider like AWS S3 or Cloudflare R2. In your config/storage.yml : amazon : service : S3 access_key_id : <%= ENV['AWS_ACCESS_KEY_ID'] %> secret_access_key : <%= ENV['AWS_SECRET_ACCESS_KEY'] %> region : us-east-1 bucket : my-app-uploads # Crucial for Direct Uploads! public : true Note: You must configure CORS in your S3/R2 dashboard to allow requests from your domain. If you don't do this, the browser will block the upload. STEP 2: The Rails Form Rails makes the backend part incredibly easy. You just add one attribute to your file field: direct_upload: true . <!-- app/views/users/_form.html.erb --> <%= form_with ( model: user ) do | f | %> <div class= "field" > <%= f . label :avatar %> <%= f . file_field :avatar , direct_upload: true %> </div> <%= f . submit "Save Profile" %> <% end %> When you add direct_upload: true , Rails automatically includes a JavaScript library that handles the "handshake" with S3. STEP 3: Adding a Progress Bar (The UX Win) Direct uploads can take a few seconds. If nothing happens on the screen, the user will think your app is broken. We can use the built-in Ac

Whether you are building SaaS, running an agency, some shop, and struggling with your hard work - you have my highest respect. The ups and downs of working on your own is a killer man, it feels great on some days and just crazy on others. It's not for every one - if someone told me about this side of building startups 12 years ago (when I started my agency), I would have given it a bit more thought tbh. Keep building and shipping, and hopefully all your work will be rewarded in a way that feels rewarding to you.

We constantly hear that Ansible and Python are apparently the only ways to automate networks, today I even listen in a conversation "Python is the industry standard" probably I missed the RFC document or probably the guy was referring to a sales standard, but back to us what happens when the framework, the platform or the software we are using becomes heavier than the problem to solve? There is a moment where automation becomes necessary, not because we want to look modern, not because every task deserves a framework and not simply because adding automation automatically means we are doing things better. It becomes necessary because repeating the same command collection manually across many devices is slow, risky, boring and almost impossible to diff and validate properly especially under pressure. For this reason I built the Cisco Go Collector during a real migration activity with a very practical goal: collect configuration and command outputs from Cisco devices in an easily repeatable way, without forcing every colleague involved in the process to become developers or to install an automation stack just to run a super simple flow. The idea was simple: define the devices in a CSV which is the comfort zone for everyone define the commands in the same CSV file, super simple and organized to manage one row per device run a portable Go binary against that CSV file collect the outputs in organized text files archive the result as operational evidence that can be easily diff That is it! super lightweight to run no Python virtual environment no Ansible playbook structure no inventory hierarchy no framework onboarding no additional runtime or software on corporate managed workstations just a CSV file and a compiled binary The automation and AI trap when the solution is heavier than the problem to solve I love automation and I fully support AI if used the proper way, but we have to find a balance and recognize when to choose one tool over the other and specially one progra
