Here's an uncomfortable truth nobody wants to admit out loud: most teams can generate a working app in minutes now, but almost none of them can ship it to production without breaking something important. Only a small fraction of organizations have actually moved their AI-built systems past the pilot stage. The gap between "it works on my machine" and "it works for real users" has never been wider, and closing that gap is quickly becoming the single most valuable skill a developer can have this year. If you have been prompting your way to a working prototype and then hitting a wall when it's time to actually deploy, this guide walks through exactly how to close that gap, with working examples at every step. Why This Matters Right Now Vibe coding, meaning describing what you want in plain language and letting an AI model scaffold the implementation, has gone from a novelty to a default workflow. Developers are shipping REST APIs , auth flows, and full CRUD apps with a single well-written prompt. But speed of generation is not the same as readiness for production. Untested edge cases, missing validation, weak error handling, and security gaps show up constantly in AI-generated code because the model optimized for "looks correct" rather than "survives real traffic." The developers who stand out this year are not the ones who can generate code fastest. They are the ones who know how to validate it, harden it, and integrate it responsibly. Below is a practical checklist you can apply to any AI-generated codebase before it touches a real user. Step 1: Treat the AI Output as a First Draft, Not a Final Answer Say your AI assistant generates this login handler: \ javascript // AI-generated first draft app.post('/login', async (req, res) => { const { email, password } = req.body; const user = await db.query( SELECT * FROM users WHERE email = '${email}' ); if (user.password === password) { res.json({ token: generateToken(user) }); } }); \ \ Looks functional. It is also a SQL in

The Subscription Fatigue is Real I was paying $47 for ChatGPT Plus, $29 for Jasper, $19 for Grammarly, $16 for Copy.ai, and $15 for an SEO tool. That's $126/month just for AI writing tools. So I built my own. Five tools, one dashboard, completely free to start. Here's how each one works and what it replaces. 1. AI Content Writer (Replaces Jasper, Copy.ai — $66/month combined) The content writer generates blog posts, articles, product descriptions, and marketing copy. You pick: Content type : blog post, article, product description, marketing copy, newsletter Tone : professional, casual, friendly, authoritative, humorous, persuasive Length : short (100-200 words), medium (300-500 words), or long (800-1200 words) The key difference from Jasper: no templates, no "brand voice" setup. You just describe what you want and get it. Simpler, faster. 2. AI Email Composer (Replaces Grammarly Business — $16/month) This one handles the emails I hate writing: Cold outreach to potential clients Follow-up emails after meetings Professional inquiries Customer support replies You set the formality level (formal, semi-formal, casual) and urgency. It writes the subject line AND the body. I've used it for 50+ cold emails last month. 3. Social Media Caption Generator (Replaces Later + caption tools — $29/month) Generates 3 caption variations per request. Platform-specific: Instagram : emojis, hashtags, engagement hooks Twitter/X : concise, thread-ready LinkedIn : professional, thought-leadership style TikTok : casual, trend-aware Options for emojis, hashtags, and CTAs are toggleable. You can mix and match from the 3 generated options. 4. AI Code Helper (Replaces GitHub Copilot Chat — $10/month) Five modes: Generate : write code from description Debug : find and fix errors in pasted code Explain : break down complex code Refactor : improve code quality Convert : translate between 20+ languages Supports Python, JavaScript, TypeScript, Java, C++, Go, Rust, SQL, and more. Not as deeply integr

If you've ever received a .pages or .numbers file on a Windows PC, you know the pain — you can't open it. No preview, no converter built in, and Apple's iCloud web tools are slow and clunky. So I built iworkviewer.com — a free, browser-based iWork file viewer and converter. No signup, no upload to any server. Everything happens in your browser. What it does Open .pages files → view them instantly, export to PDF or .docx Open .numbers files → view spreadsheets, export to .xlsx or PDF Open .keynote files → view presentations, export to PDF or .pptx Batch convert multiple iWork files at once The tech Built with Next.js, Cloudflare Pages, and pure client-side JavaScript. All file processing happens in the browser — your files never leave your computer. Zero server costs, zero privacy concerns. Why I built it I kept seeing Reddit threads and Quora questions: "How do I open a Pages file on Windows?" The answers were always the same — use iCloud.com (slow), download some sketchy converter (risky), or ask the sender to export as PDF first (annoying). I figured: if the browser can read a file, it can convert it. And it turns out, it can. Try it 👉 iworkviewer.com Open a .pages, .numbers, or .keynote file right in your browser. Free, forever, no account needed.

I have been building AI products for a while and kept running into the same problem. Every project that involves querying documents with AI requires the same foundation before you can build anything interesting: a chunking strategy, an embedding pipeline, a vector database, re-ingestion logic when content changes, and a retrieval layer on top. It is not hard, it is just a lot, and it is not the part you actually want to be building. So I built Kognita to handle it as a managed API. You push content in via API, text or files, and get back hybrid search over a knowledge base. Kognita handles chunking, embedding, indexing, and automatically re-embeds when you update content. It is opinionated: we pick the embedding model and chunking strategy. The trade-off is less flexibility for a much faster path to a working knowledge layer. What we are looking for We want 10 teams who are building something that needs a knowledge layer and are willing to test it honestly. The ask is: what broke, what was confusing, what you needed that was missing. Not looking for compliments. Looking for people who will actually use it and tell us where it falls short. What you get Unlimited knowledge bases 10 GB storage 100 GB egress per month 50 GB file storage No credit card. No time limit. Higher than our standard paid plan. Who it is for Engineering teams building AI features over documents who do not want to manage the underlying infrastructure themselves. If you need full control over your embedding models or retrieval strategies, this is probably not the right fit. If you want to skip the pipeline and get to building, it might be.

The Token Bucket Algorithm: Server-Side API Rate Limiting in ~40 Lines Plenty of tutorials teach you how to survive someone else's rate limit with retries and backoff. Far fewer show you how to build one. If you run an API, you need rate limiting on your side too — to protect your database from a runaway client, keep one noisy tenant from starving everyone else, and give abusive traffic a polite 429 instead of a melted server. The cleanest algorithm for the job is the token bucket . Let's implement it from scratch, then make it production-ready. How token bucket works Picture a bucket that holds up to capacity tokens. Every request removes one token. The bucket refills at a steady refillRate (tokens per second), up to its cap. If a request arrives and the bucket is empty, it's rejected. This gives you two useful properties at once: A sustained rate — the long-run average, set by refillRate . A burst allowance — clients can spend the whole bucket at once, set by capacity . That burst tolerance is why token bucket feels fair. A user who's been quiet for a minute can fire off a batch of requests without being punished for it. A minimal implementation Here's a self-contained bucket in JavaScript. No dependencies, no timers — we compute refill lazily based on elapsed time, which is both simpler and more accurate than a background interval. class TokenBucket { constructor ( capacity , refillRatePerSec ) { this . capacity = capacity ; this . refillRate = refillRatePerSec ; this . tokens = capacity ; this . lastRefill = Date . now (); } _refill () { const now = Date . now (); const elapsedSec = ( now - this . lastRefill ) / 1000 ; this . tokens = Math . min ( this . capacity , this . tokens + elapsedSec * this . refillRate ); this . lastRefill = now ; } take ( cost = 1 ) { this . _refill (); if ( this . tokens >= cost ) { this . tokens -= cost ; return { ok : true , remaining : Math . floor ( this . tokens ) }; } const deficit = cost - this . tokens ; const retryAfter = Mat

Web Scraping with Python in 2026: Best Libraries and Anti-Bot Strategies Web scraping in 2026 looks very different from 2020.

Breaking long documents into overlapping chunks, preserving context, and reassembling with FastAPI At LectuLibre, we’ve built an AI‑powered platform that translates entire books—EPUBs and PDFs—using large language models. When we first hooked up Claude’s API, we naively fed it a 300‑page PDF in one request. It failed immediately. Claude 3 Opus has a 200K token window, but a 300‑page book can easily run to 300K tokens or more. Even if we squeezed it in, the output would be truncated and the quality would degrade at the extremes of the context window. So we faced a classic long‑document problem: how do you translate a book that’s larger than the model’s context window? Here’s the real approach we ended up with, the code we wrote, and the lessons we learned. The Problem: Token Limits Are Real Claude 3 Opus and Haiku models (and most LLMs) have a maximum context length—200,000 tokens for Opus. A token is roughly ¾ of a word. A 300‑page novel with ~75,000 words translates to about 100K tokens, so it should fit, right? But translations from English to Spanish can expand by 15–20%, and the prompt instructions, system message, and the user message itself all eat into that budget. Plus, we needed to send the entire source text in every call to give the model full context. That’s not feasible. We could have tried a simple split: cut the book at arbitrary page boundaries and translate piecemeal. That fails spectacularly. Narrative breaks mid‑sentence, and phrases like “the previous chapter” lose their referents. We needed a more intelligent chunking strategy. Our Approach: Sliding Window with Overlapping Paragraphs We settled on a sliding window chunking algorithm based on paragraphs, with a generous overlap. Here’s the idea: Split the source text into paragraphs (using \n\n ). Build chunks of max_chunk_tokens (we used 180,000 to keep a safety margin), adding paragraphs one by one and counting tokens with tiktoken . When the chunk exceeds the limit, we start a new chunk but we

A reviewer that flags the same known issue on every run trains you to ignore it. The fix can't be "hide findings," because a tool that silently drops things is worse than one that nags. CommitBrief has two ways to accept a finding and move on — a per-developer baseline and an in-source suppression marker — and both are built so that what they remove is always counted, never quietly swallowed. The interesting part is how a finding keeps its identity when the code around it moves. TL;DR Baseline ( .commitbrief/baseline.json , gitignored): accept the current findings once; later runs drop anything whose fingerprint is already in the file. Inline suppression : a commitbrief-ignore: <reason> comment on or above a line removes that finding — and lives in committed source, so a reviewer sees it. A finding's fingerprint deliberately excludes its line number , so accepting it survives the code drifting up and down the file. Both are TRUE removals — they affect --fail-on and the JSON findings[] , not just the display — and both print what they removed. The limit. The baseline is per-developer, not a shared team policy; it quiets your runs, not CI's. The fingerprint that survives code drift The whole design rests on one question: when is a finding "the same finding" you already accepted? If the answer included the line number, a baseline would evaporate the moment you added an import above the issue. So it doesn't. A finding's identity is three fields, hashed: func normalizeTitle ( title string ) string { return strings . ToLower ( strings . Join ( strings . Fields ( title ), " " )) } func Fingerprint ( f render . Finding ) string { h := sha256 . New () h . Write ([] byte ( f . File )) h . Write ([] byte { 0 }) h . Write ([] byte ( f . Severity )) h . Write ([] byte { 0 }) h . Write ([] byte ( normalizeTitle ( f . Title ))) return hex . EncodeToString ( h . Sum ( nil )) } File, severity, and a normalized title — and nothing else. Line is out, so the same issue keeps its finger

A year ago today, I started at Approov. A hundred days in, I wrote about the transition: leaving management, the refreshing day-to-day feedback loop, the strange experience of relearning a craft I thought I'd lost. I stand by most of it. But a hundred days is enough to notice a change; it takes a year to understand it. So here is what a year taught me that a hundred days couldn't. The rust that mattered At a hundred days I called myself rusty. I was. I reached for patterns that no longer fit and looked up syntax I once knew by heart. I expected that to be the hard part. It wasn't. The rust came off faster than I feared, and somewhere along the way I realised I'd been worried about the wrong thing entirely. The agentic era arrived in earnest this year, and it quietly rewrote the job description. The premium skill is no longer how fast you can produce code from memory. It's whether you can write a precise specification and make a strong architectural decision, then judge honestly whether what comes back is any good. Those are not new skills for me. They are the exact skills that years of reviewing architecture and mentoring engineers had been sharpening the whole time. The craft I sat down to relearn was not the craft that turned out to matter. I spent years assuming management had pulled me away from engineering. It hadn't. It had been quietly preparing me for the version of engineering that was coming. Charity Majors has a name for the shape of this: the engineer/manager pendulum. The idea that a healthy career swings between the two, rather than treating management as a one-way door you walk through once and never come back. I didn't choose when mine swung back. But it swung the right way, and the years spent on the other side weren't lost. They were compounding. A secure transaction is a secure transaction The work itself has been a homecoming of a different kind. I spent years in payments. Now I work in mobile and API security. On paper those are different worlds

A narrativa atual da tecnologia está fortemente inclinada para a automação. Com agentes de IA escrevendo boilerplate , gerando componentes e até estruturando projetos inteiros, é fácil olhar para o futuro do desenvolvimento de software e assumir que o elemento humano está diminuindo. Mas se você mantém ou contribui ativamente para um projeto open source , sabe que a realidade é bem diferente. A IA pode escrever código, mas não consegue validá-lo contextualmente contra décadas de edge cases obscuros. Ela não sabe dizer por que uma regra de negócio específica falha em produção. Mais importante ainda: a IA não constrói comunidade. A evolução de um software robusto ainda depende inteiramente de pessoas colaborando, quebrando código, reportando bugs e validando se o código realmente funciona no mundo real. Para ver isso na prática, precisamos olhar para projetos que tentam fechar lacunas geracionais gigantescas na tecnologia. Um exemplo perfeito disso é o AxonASP . A Filosofia do AxonASP: Modernizando o Legado Por muito tempo, o ASP Clássico e o VBScript foram considerados presos a um modelo de servidor obsoleto — amarrados ao IIS e deixados para trás pelas práticas modernas de deploy . O AxonASP muda esse cenário. É um runtime open source e cross-platform que trata o ASP Clássico como uma Aplicação moderna, em vez de uma relíquia do passado. Ele traz o VBScript, o ASP e, principalmente, o suporte ao JavaScript Síncrono para o futuro. Construir um runtime que lida com código legado enquanto opera em um ecossistema moderno e multiplataforma não é algo que você consegue simplesmente pedindo para um LLM. Exige um ciclo de feedback agressivo. O AxonASP está em franca evolução e apresenta altíssima compatibilidade com o ASP Clássico. Mas essa compatibilidade não é mágica — ela é o resultado direto de usuários pegando seus scripts legados de 15 a 20 anos atrás, rodando no motor, vendo onde falham e reportando exatamente o que aconteceu.

June was not about making the most contributions -- it was about becoming a better collaborator. This month I had: ✅ 1 PR merged 🔄 1 PR still open 👀 3 PR reviews completed 🐞 1 issue opened I am making this graph all green... Biggest Learning The biggest milestone wasn't writing code. It was reviewing pull requests. One review led the author to update their PR based on my feedback. That experience taught me that open source isn't just about contributing code; it's also about helping improve someone else's work through discussion and constructive feedback. Working Alongside AI Reviewers I also had an interesting experience interacting with automated reviewers like Vercel Bot and Copilot. Rather than accepting every suggestion, I tested them, evaluated the trade-offs, and explained why I chose a different approach. It was a good reminder that AI can assist reviews, but engineering judgement still matters. Looking Ahead My biggest challenge is still finding a larger project that I can consistently contribute to over the long term. That's my main goal for July, alongside publishing my OSS Contribution Toolkit repo and making my CaaS project usable for others. Small, consistent steps continue to move the journey forward. What was your biggest open source learning in June? Transparency Note: I used AI as an editor—not as the author. For this article, it helped refine the structure and improve the English grammar. The technical content, experiments, opinions, and conclusions are my own and were reviewed by me before publishing.

3 platforms, one queue, zero editorial control. That was the state of my content automation before I sat down to spec the dashboard. LinkedIn, X, and Threads each had their own generator, their own state files, their own publishing loop. Drafts got generated, passed a quality gate, and fired into the void. If the draft was mediocre or the timing was wrong, I found out after the fact. The problem is not the automation. Automation is why I can run three platform engines without spending two hours a day managing content. The problem is that zero editorial visibility means you cannot catch the bad ones before they post. What I wanted: see every draft before it goes out. Edit inline if needed. Post immediately or schedule for the next slot. Compose something manually when I have a specific take to push. Keep the comment automation untouched because that runs high frequency, low stakes, and babysitting individual replies defeats the point. The spec came out to three core flows. Review queue. Every pregenerated draft surfaces here with full context: platform, topic, generation timestamp, quality score. One click to edit inline, one to approve for the next slot, one to post immediately. The goal is a 30 second review per draft, not a full editing session. Manual compose. Sometimes I know exactly what I want to say. A text area, platform selector, and post button. No generation, no queue, just publish. This is the escape hatch for when something is happening in real time and the pregenerated queue is irrelevant. Schedule view. A simple calendar showing what is queued for which slot across all three platforms. The generator already handles slot logic and quiet hours. The dashboard just needs to surface the state so I can see gaps and move things around without touching JSON files directly. What I deliberately left out: comment automation. That pipeline runs separately, fires frequently, and does not benefit from human review on every reply. Adding it to the dashboard would cr

"Privacy by design" is one of those phrases you read everywhere and rarely understand. It is often treated as a document to attach to a project, a box to tick before going live. In reality it is not a piece of paperwork: it is the way software is conceived and built from the very first line, so that it protects people's data without anyone having to remember to do so afterwards. What the GDPR actually says The principle is written plainly in Article 25 of the GDPR, which speaks of "data protection by design and by default". These are two distinct things. Protection by design concerns the choices made while the system is being built. Protection by default concerns how the system behaves the moment it is switched on, before anyone touches a single setting. The law does not mandate a specific technology. It asks for an outcome: that data protection be built into the system, proportionate to the risks, and not bolted on afterwards as a patch. It is a difference of substance, not of form. A well-designed system does not have to chase compliance: it already has it inside. It is not a document, it is an architecture The most common mistake is to reduce privacy by design to a file. A report is written, filed, and the building goes on exactly as before. But a PDF protects no data. What protects data are the technical decisions: what information is collected, where it is stored, who can see it, how long it stays, what happens when it is no longer needed. These decisions are made at design time, and changing them later costs far more than getting them right at the start. The principles, turned into concrete choices Privacy by design becomes useful only when it stops being a slogan and turns into a series of choices. Translated into practice, the principles sound like this. Minimisation. You collect only the data genuinely needed to deliver the service. A field you do not collect does not need protecting, cannot be lost in a breach, does not need keeping. The safest piece of da

Subtitle: Build a Python app with Telnyx AI Inference that turns customer activity signals into churn risk, recommended actions, and retention next steps. Most customer churn is only surprising because the signals were scattered. Usage dropped in one place. Support tickets went up somewhere else. A renewal date got closer. A login did not happen for two weeks. Payment issues started showing up. None of those signals alone proves a customer is leaving, but together they usually tell a story. That is the workflow I wanted to make easier to build: take customer activity data, pass it through an inference model, and return a structured churn assessment that a product or customer success team can actually use. The example is here: https://github.com/team-telnyx/telnyx-code-examples/tree/main/ai-customer-churn-predictor-python It is a small Flask app using Telnyx AI Inference through the chat-completions API. The App Shape The app exposes a few routes: POST /predict for one customer POST /predict/batch for up to 20 customers GET /predictions for recent in-memory predictions GET /health for app health The current default model is set in .env.example : AI_MODEL=moonshotai/Kimi-K2.6 Under the hood, the app calls: POST https://api.telnyx.com/v2/ai/chat/completions The prompt asks the model to behave like a customer success analyst and return JSON only. That is the important part. This is not a chatbot. It is an application endpoint that produces structured output. What Goes In A request can look like this: curl -X POST http://localhost:5000/predict \ -H "Content-Type: application/json" \ -d '{ "customer_id": "CUST-123", "call_volumes": [120, 105, 80, 55], "message_volumes": [450, 420, 300, 190], "support_tickets": 6, "account_age_months": 18, "renewal_days": 21, "last_login_days": 14, "payment_issues": 1 }' Those fields are deliberately simple. The point is to show the pattern, not to pretend this is a full enterprise churn model. The model gets the trend data, support contex

A conference sold out three separate ticket tiers before the doors even opened. Not "almost sold out." Sold out — Leadership track, gone. Workshops, gone. Late bird tickets, gone. The organizers stopped counting around 6,000 attendees and said they'd officially call it once they crossed 7,000. That's the AI Engineer World's Fair in 2026, and if you've spent any time building with LLMs over the last three years, you already know the name even if you've never been able to get a ticket. I want to walk you through what's actually happening on the ground this week at Moscone West in San Francisco — not the marketing copy, but the track list, the speaker lineup, and the quiet signals buried in the schedule that tell you where AI engineering is actually heading next.

Why It Matters What Makes It Different Key Technologies AI Agents LLM Engineering MCP RAG Fine-tuning AI Infrastructure Workshops Networking Startups Enterprise AI Major Takeaways Future of AI Engineering Final Thoughts What is AI Engineer World's Fair? AI Engineer World's Fair is the flagship conference run by AI Engineer, the company behind a whole circuit of events — the AI Engineer Summit, Code Summit, and standalone editions in London, New York, Paris, Miami, Singapore, Shanghai, and Melbourne. The World's Fair is the biggest of them all: a four-day event with 29 tracks, 300 speakers, 100 expo partners, and more than 6,000 AI engineers, founders, and VPs of AI in attendance. The 2026 edition runs from Monday June 29 through Thursday July 2, with a Sunday evening orientation night tacked on for first-timers. It's held at Moscone West, 747 Howard Street, in San Francisco. This is the fourth year the event has anchored in San Francisco, and the organizers have leaned into that — discounted hotel blocks at the Marriott Marquis, Parc 55, and InterContinental, all walking distance from the venue. The person behind all of it is Shawn "swyx" Wang. He's the cofou

A customer texted me a screenshot last month. It was my own landing page, open on their Pixel. The headline — "Financial infrastructure to grow your revenue" — was clipped at "...grow your reven". The signup button below it was gray-on-slightly-lighter-gray, basically unreadable. And the hero image? A broken-image icon. Here's the part that stung: every check I had was green. Lighthouse: 98. My Playwright tests: passing. CI: all checkmarks. I had shipped that page an hour earlier feeling good about it. None of my tooling caught any of it. I want to walk through why , because I think a lot of us have this blind spot, and then I'll tell you what I did about it. CI tests the DOM. It does not test what a human sees. This is the core issue. My tests asserted things like "the signup button exists" and "the form has an email input." All true. The button was in the DOM . It just rendered unreadable on a 412px-wide screen with the system in light mode. Lighthouse runs one viewport (usually a throttled Moto G4 emulation) and scores performance/SEO/a11y heuristically . It does not look at your page across the actual range of devices your visitors use and say "this headline is physically clipped on a Pixel 8." And my "responsive testing"? I was dragging the Chrome devtools responsive bar to two breakpoints — 375 and 1440 — eyeballing it, and moving on. That's not testing. That's hoping. The three bugs that slipped through Let me get specific, because the category of each bug is instructive. 1. The clipped headline — a measurable, deterministic bug .hero-title { white-space : nowrap ; /* the culprit */ width : 100% ; overflow : hidden ; } On desktop, the headline fit. On a narrow viewport, white-space: nowrap refused to wrap, overflow: hidden clipped the overflow, and the last word vanished. The brutal thing: this is trivially detectable in code . The element's scrollWidth was greater than its clientWidth . That's a one-line check: const clipped = el . scrollWidth > el . clientW

The Quest Begins (The "Why") Honestly, I was tired of playing “guess the state” every time I spun up a new environment. One day I clicked “Apply” in the AWS console, watched a handful of EC2 instances, S3 buckets, and IAM roles appear, and then realized I had no idea how to recreate that exact setup six months later when the team needed a staging copy. It felt like trying to rebuild the Death Star from memory after a single glance at the blueprints—frustrating, error‑prone, and definitely not the heroic saga I signed up for. That moment was my “aha!”: I needed a repeatable, version‑controlled way to describe infrastructure. Enter Infrastructure as Code (IaC). I’d heard the buzz, but the real question was which tool to wield—Terraform or CloudFormation? Both promised declarative provisioning, but they spoke different dialects. I decided to embark on a quest to learn both, slay the configuration drift dragon, and come out with a reusable spellbook I could share with anyone on the team. The Revelation (The Insight) The breakthrough came when I stopped thinking of IaC as “just another config file” and started seeing it as a storytelling language . Every resource block is a character, every variable a plot twist, and the state file the ever‑growing script that remembers what happened in previous chapters. When I wrote my first Terraform module, it felt like Neo realizing he could bend the spoon—suddenly the impossible became trivial. I could define a VPC, subnets, security groups, and an RDS instance in a few dozen lines, run terraform init , terraform plan , and watch the plan show exactly what would change before any resources touched the cloud. No more surprise “you created a public‑facing DB!” moments. CloudFormation, on the other hand, felt like the loyal sidekick that already lives in the AWS universe. Its JSON/YAML templates are native to AWS, so there’s no extra provider to install, and drift detection is built‑in. The trade‑off? A bit more verbosity and a steepe
