I uploaded a 40-page PDF of an internal API spec, asked "what's the rate limit for the search endpoint?", and got back: "100 requests per minute per API key, with bursts up to 200. See section 4.2 of the document." With citations. In about three seconds. The whole stack runs on my laptop. It cost me $0 in LLM credits during development because Ollama is free and local, and the embedder I used is also free and local. The repo is here — issues and PRs welcome. This is the build log. Not a tutorial where every step works the first time — a build log where I tell you which decisions held up and which ones I redid. The problem most "chat with your PDF" demos have Every "chat with your PDF" tutorial I read in early 2025 had the same shape: open OpenAI, paste your API key, call gpt-4 with a 50-page PDF stuffed into the context window, get an answer, pay $0.03 per question, repeat. That works for a demo. It does not work for a tool you'd actually use at work, because: The PDF might contain customer data, internal pricing, or unreleased features. You do not want that going to OpenAI's training pipeline or anyone's logs. The cost adds up. If your team uses it 50 times a day, that's $45/month per seat. The model hallucinates on long PDFs anyway. Stuff 100 pages into a 128k context window and the model starts forgetting the middle. The fix is RAG (Retrieval-Augmented Generation) — don't send the whole PDF, send only the 3-5 chunks that are actually relevant to the question. The rest of the work is the same: embed the chunks, embed the question, find the closest matches, send those to the LLM with the question. But the cost and the privacy story both improve by 100x. The actual ask: Upload a PDF. Ask questions. Get answers from the document with citations, in under 5 seconds, with no data leaving my laptop and no monthly bill.

Last Tuesday my API gateway caught a NullReferenceException , streamed it to a dashboard in real-time, and pushed a draft code fix to the browser tab of the on-call engineer — before I finished reading the error myself. That sentence used to be vendor marketing. Now it's just my Program.cs . This is the architecture post-mortem. I built it on weekends. It runs in Docker. It cost me exactly $0 in LLM credits during development because Groq's free tier is generous and Ollama works as a swap-in. The repo is here — issues and PRs welcome. The problem most .NET teams have Production errors are caught, logged to a file, and forgotten. Engineers find out from a Slack ping twenty minutes later, if at all. By the time someone looks, the original request context is gone, the user's session has expired, and the stack trace is buried four layers deep in System.* calls. "Self-healing" is a word vendors use to mean "auto-restart the pod." I wanted something better. The actual ask: When an exception is thrown in service A, give the engineer (a) a clear root cause, (b) a suggested fix, and (c) a draft code patch — in under 30 seconds. Not a magic black box. Not an auto-applied patch. Just: catch the error, give the model the right context, push the analysis to a human in real-time, and let the human close the loop. The architecture One .NET solution, four projects, four NuGet packages, no new infrastructure beyond what you probably already have.

Pagination is a key component on web-applications that let users navigate through pages making easy to read/find records. Also, pagination is a great strategy to improve performance by avoiding to load entire dataset at once. However, while working with Kaminari, a popular pagination gem in Rails, I encountered an unexpected issue that revealed an interesting edge case. Identify the issue Basically, pagination in frontend was not working properly. Datatable should load 316 total rows, although when the user started to load 15 records per page, frontend is showing inaccurate total rows. Multiple of 15 should ends at 0 or 5. There were pages with 64 records, crazy world. Some pages were loading 12 or 11 rows. There is no issues or error messages in the frontend or backend. Lost in debugging-land After discarding Angular frontend errors, I started to dig into backend controller and Kaminari configuration. Nothing seems wrong. Everything looked good: test suite, smoke tests, desktop debugging. Despite of test results, I started to wonder: what if returned-data is wrong after all? and... Bingo! Finally, after checking every response I noticed that there were duped records in two different pages(pagination requests). Those duped records were skipped from Angular data-table and that's why loaded/total rows did not match. Bingo: a sort of mistake This tricky bug has a simple explanation: bad sorting. Kaminari uses a SQL query using LIMIT/OFFSET strategy: SELECT * FROM posts ORDER BY id LIMIT 25 OFFSET 0 ORDER BY : sort the collection. LIMIT : number of records per page. OFFSET : is used to skip a specified number of rows before starting to return rows from a query. This works perfectly using ORDER BY id because primary key is unique.

Most engineering reading lists are optimized for knowledge accumulation. Modern engineering rewards bottleneck elimination. Last week, a junior engineer showed me a "Top 10 Books Every Engineer Should Read" list. It looked almost identical to the lists I saw ten years ago. The same classics. The same process books. The same assumption: Read enough books and you'll become a better engineer. That's not how most high-performing teams learn. The best engineers I know don't build learning plans around books. They build learning plans around constraints. The Problem with standard reading lists Most reading lists assume that knowledge is universally valuable. In practice, engineering value is highly contextual. A backend engineer struggling with database contention does not need another chapter on Agile. A team spending thousands of dollars per month on LLM inference does not need a generic software craftsmanship book. A startup fighting latency issues does not need a leadership framework. They need solutions to the bottleneck directly in front of them. Reading lists rarely account for this. They optimize for completeness. Engineering rewards relevance. The Shift Most Engineers Miss The fundamentals still matter. Distributed systems matter. Databases matter. Networking matters. Operating systems matter. They are not obsolete. But they are no longer sufficient. Modern systems introduce constraints that barely existed a few years ago: AI inference costs Context window limitations Agent orchestration Evaluation pipelines Semantic caching Non-deterministic workflows Model routing Human-in-the-loop systems Many traditional reading lists never touch these problems. Yet these are exactly the problems teams are solving every day. The challenge is no longer simply writing correct software. The challenge is building reliable systems on top of components that are inherently probabilistic. What Changed For decades, engineers mostly worked with deterministic systems. Given the same inp

In a world completely powered by technology, have you ever wondered what actually keeps our digital lives from crashing down? Enter the unsung heroes: system and network administration . Think of an operating system like Windows or Linux as a computer's command center, orchestrating everything from the heavy-lifting CPU to the smallest plugged-in device. To keep your data safe and your machine stable, it cleverly splits its brain into two zones: a restricted "user mode" where your everyday apps play, and a highly secure, privileged "kernel mode" reserved strictly for critical system operations. When individual computers connect to form massive global networks, the complexity skyrockets. This comprehensive guide breaks down those complex environments into simple, bite-sized concepts. Here is a quick snapshot of what we will cover: Host & OS Administration : This module covers how an operating system functions as the primary intermediary between a user and a computer's raw physical hardware. It explains how the system kernel manages critical computing processes, memory allocation, local storage file systems, and administrative tasks like security patching and automated scripting. Networking Concepts, Topologies, and Protocols : This module explores how individual computer systems connect and communicate across localized or global distances. It details the structural design of network topologies, addressing rules like IPv4 and IPv6, and the standardized layer frameworks that ensure safe and efficient data transmission. 🏛️ Part 1: Operating Systems & Host Administration 🖥️ Computer Resources and Functions At its core, every computer system is a collection of physical machinery and digital structures working together to solve problems. To understand how an operating system manages these pieces, it helps to look at the foundational puzzle blocks of a computer. This section maps out the primary hardware and data elements the system has to control, alongside a simple breakd

I used to think tests were a waste of time. "Ship fast, fix later" was my motto. Until I spent three painful weeks debugging a production issue that a simple test would have caught in 30 seconds. That was the day I became a believer. The Harsh Reality Most Solo Developers Ignore If you're a freelancer or indie hacker building real products for clients, here’s what happens without good tests: You make a "small change" and something unrelated breaks Clients find bugs you should have caught Refactoring becomes terrifying You lose sleep before every deployment Your reputation slowly takes hits A solid test suite changes all of that. What a Test Suite Actually Gives You Confidence to Move Fast You can refactor, add features, or upgrade dependencies without fear. Living Documentation Your tests explain how the system should behave — better than comments ever could. Early Bug Detection Catch issues before they reach the client or production. Better Architecture Writing testable code forces you to write cleaner, more modular code. Professional Credibility When clients or senior devs review your code, a good test suite immediately signals seriousness. The Test Suite Pyramid I Actually Use Unit Tests (70%) → Test individual functions and components Integration Tests (20%) → Test how different parts work together (API + DB) End-to-End Tests (10%) → Critical user flows (login → checkout → etc.) I don't aim for 100% coverage. I aim for high-value coverage — especially around business logic and critical paths. Final Thought Writing tests feels slow at first. But it compounds. Every month you have tests, you move faster and sleep better. The developers who ship reliable software consistently aren't necessarily the smartest — they're usually the ones who learned to respect testing. Have you built a strong test suite habit yet? Or are you still in the "I'll test it manually" phase? Drop your experience below. Let's talk.

Working with AI Means Thinking More, Not Less Yes, this text is long. Yes, it repeats itself in places. I did not clean that up. A text that sounded too smooth while arguing that AI forces you to think more, not less, would be at least slightly dishonest. This is not fast food for quick consumption. And yes, don’t worry: you won’t hear anything especially new here. That is part of the problem too. There is a popular and very seductive story about AI in software development. Now that the machine can write code, the human gets to think less. You just point it in the right direction, and the model will quickly and cheaply do a significant part of the work on its own. In that picture, AI is primarily an accelerator for code production, and human thinking gradually shifts from necessity to optional extra. I keep feeling more and more strongly that this description is dangerously wrong. A more accurate formula for my own experience right now is this: I’m the tech lead, the AI is the entire team in one body . And if you take that metaphor seriously, the conclusion is the exact opposite of the mainstream narrative. Working with AI is not a way to think less. It is a mode in which you need to think more, not less . Not because the AI is bad. But because it is too good at one very treacherous thing: it confidently and smoothly fills in what was left unsaid. I’m the tech lead, the AI is the team At first this metaphor felt like a neat formulation. Now it feels like a literal description of what is going on. If you treat AI as a very fast and very capable executor, a lot of things become clearer immediately. It really can wipe out months of routine work. It can spin up prototypes quickly, take over test scaffolding, try out alternatives, make local edits, help break a task into parts, and sometimes even suggest a decent direction. On the surface, this really does look like a silver bullet. Especially if the human knows the stack and can read code. The pace becomes so extreme th

A working prompt library is the main event, not an appendix. The industry still treats prompts as some half-baked spitball left in a README, or, worse, a plaintext blob stapled to package.json and forgotten. That's a waste of compute and credibility. What powers reliable AI-assisted refactoring, onboarding, or even next-gen code IDEs is not the size of the model but the clarity and context supplied by the actual, shipped prompt set. OTF kits turn this lesson into a repeatable deliverable: every paid template includes 20+ production-tested prompts tied to the real file structure, component API, and product-specific conventions. This is not a suggestion; it's structural. The takeaway: a real prompt library is as important as your component library. Treat it like one. Start with the pain: why blank chat boxes don't scale The web is full of “integrations” that paste a blank chat input over your codebase and call it an “AI coding assistant.” The result: hallucinated function names, invented conventions, broken import paths. Here’s what happens in real life: Dev: "Add a social login button." AI (blank prompt): "Sure! Insert <SocialLoginButton> in your LoginScreen.js." Dev: (There’s no such component. There's not even a LoginScreen.js.) Short: A generic prompt with zero context simply can't know your conventions, files, or patterns. The agent will either fail, hallucinate, or pepper you with clarifying questions you have already answered in your product architecture. Takeaway: Prompting without context is coding without types — fragile guesses instead of structured outcomes. What a first-class prompt library enables When the prompt library ships with the codebase, it looks like this: Every prompt knows the folder structure (e.g., features/auth , screens/Settings/index.tsx ). Conventions are hard-coded: naming, import styles, design token usage. Endpoints and integration points (e.g., “update the Stripe webhook handler in api/webhooks/stripe.ts ”) are spelled out. The promp

Hey dev.to community! 👋 Over the last few months, juggling my roles as a Project Manager, Scrum Master, and lead for QA, Support, and Documentation has been a wild ride. The sheer speed of "vibe coding"—a paradigm shift where the primary role of the developer transitions from manual code construction to high-level intent orchestration—is incredible. Tools like Cursor, Replit Agent, and Google Antigravity allow us to scaffold entire microservices in minutes. However, while this transition offers unprecedented generative velocity, it introduces systemic risks concerning architectural integrity, long-term maintainability, and security. That’s why I’m sharing Cronos (Version 2.0) : a new, strategic methodology I’ve formalized for human-validated vibe coding and agentic software engineering. Real-World Testing & The Multi-Track Approach We have been rigorously testing this framework with our team over the last three months. The empirical results have been fantastic, tracking closely with the framework's theoretical efficiency models to deliver an almost 4x gain in productivity. To maintain production stability while achieving this speed, we adopted a multi-track approach. We continue to use standard Scrum for our maintenance track, which handles smaller tasks, support requests, and standard bug fixes. Meanwhile, Cronos is deployed exclusively for our parallel feature track, tackling larger Epics and new feature development. This ensures production stability does not stall innovation velocity. What is Cronos? The genesis of Cronos lies in the recognition that traditional Agile methodologies often fail to keep pace with the collapsed feedback loops of AI-driven development. In the current agentic era, the bottleneck has shifted from implementation to validation and strategic alignment. Cronos reconfigures the software development lifecycle (SDLC) around one-week "Cycles". Each cycle is a burst of high-intensity, AI-augmented creation coupled with a fixed duration of human

A field guide to the practice that's reshaping how software gets built with AI agents. TL;DR — Spec-Driven Development (SDD) makes a precise, executable specification the source of truth and treats code as a generated, verifiable artifact. The spec declares intent ; the code realizes it. In 2026 it went mainstream because AI agents are great at writing code and terrible at guessing what you meant. Jump to: Why now · Specs vs. executable specs · Maturity model · Workflow · Tooling · EARS · Worked example · Caveats · Bottom line Why now? The "vibe coding" backlash The movement defines itself against "vibe coding" — the term Andrej Karpathy popularized in early 2025 for loosely prompting an AI and shipping whatever comes back. Vibe coding is great for throwaway prototypes and miserable for anything that has to be maintained. SDD is the disciplined counterweight: if AI writes most of the code, then the specification becomes the highest-leverage artifact a human produces . The skill that matters shifts from typing the implementation to defining the intent precisely enough that a machine can't get it wrong. Raw specs vs. executable specs This is the single most important distinction in the whole topic — and the one most "SDD explainers" skip. Traditional design docs SDD specs Read by Humans Humans and agents Enforcement Advisory — devs may diverge Executable — tests fail on drift Lifecycle Goes stale, becomes archaeology Living, continuously validated Lives in A wiki nobody opens The repo + CI/CD "Traditional specs are read by humans, while SDD specs are executed as BDD scenarios, API contract tests, or model simulations." — Deepak Babu Piskala, Spec-Driven Development: From Code to Contract in the Age of AI Coding Assistants (arXiv, Jan 2026) [2602.00180] Spec-Driven Development:From Code to Contract in the Age of AI Coding Assistants The rise of AI coding assistants has reignited interest in an old idea: what if specifications-not code-were the primary artifact of softw

Pre: What is BlockSocial? BlockSocial is the ultimate social network for developers, bringing the energy of short-form video to the world of open source. Think of it as Facebook meets Instagram—a place to showcase your code, find inspiration, and build your developer brand through "Reels" and interactive dashboards. Github link: https://github.com/Hfs2024/BlockSocial 1. User Scenario & Workflow (The Fork System) The Setup User A : Publishes a post saying: "I love drinking Pepsi every day." User B : Is shy, but wants to tell their friend this is an unhealthy habit. User C : Is a malicious user who gossips. The Fork Mechanism User B creates a fork to discuss this post with User C via the POST /api/share endpoint. Data Copying : It copies the entire post contents except comments, likes, reports, and downloads. Chain Prevention : You can fork a forked post, but the system will fork the original source root, not the fork itself. Scope : It shares with only one user at a time to prevent unexpected group creation. Database Payload for Forks The following fields are appended to the document structure: { "share" : true , "shareId" : "post._id" , // The original post ID "sharedBy" : "req.currentUser.username" , // The user who shared or forked "shareTo" : "shareTo" , // The friend receiving the share "shareComment" : "comment || ''" // A quick comment on the post } Moderation & Enforcement Workflow If User C breaks trust and leaks the conversation, User B can report them via the POST /report/user endpoint. Verification : Administrators review interaction history to verify the violation. Account Termination : Bad users receive a permanent lifetime account ban. Data Scrubbing : All associated messages from the malicious user are removed. Blacklisting : The account is fully banned. The Blindspot : Face-to-face interactions remain outside system moderation boundaries 😅 2.

A few months ago, I was overwhelmed by everything happening in AI. Every week there was a new coding assistant, a new workflow, or someone claiming they built an app in just a few hours. It felt like if you weren't keeping up, you'd be left behind. I tried almost everything. Cursor. ChatGPT. Claude Code. Lovable. At first, I kept switching between tools, hoping one of them would magically make me a better developer. It didn't. The biggest lesson I learned wasn't about choosing the best AI tool. It was learning how to work with AI. These days, I don't start by asking AI to write code. I start by explaining the problem. I describe the feature, the business requirements, the edge cases, and what I want the final result to look like. Sometimes I ask ChatGPT to help me plan the implementation first. Once everything is clear, I pass that plan to an agentic coding assistant and start building. That one change made a huge difference. I spend less time writing boilerplate and more time thinking about architecture, user experience, and solving the actual problem. AI still gets things wrong, so I review everything before it goes into production. But instead of writing every single line myself, I'm guiding the process. Looking back, the first few months were the hardest. Now it just feels normal. The tools will keep changing, but I think the real skill is learning how to communicate with AI and use it as part of your development process. That's something worth investing in.

Why Taking Feedback Positively Can Change Your Career As developers, engineers, designers, and professionals, we all want to improve. We spend countless hours learning new technologies, building projects, and gaining experience. Yet many people overlook one of the most powerful tools for growth: feedback. Unfortunately, feedback often feels personal. When someone points out mistakes in our code, resume, communication, or project, our first reaction is sometimes defensive. We feel offended, frustrated, or misunderstood. I've experienced this myself. But over time, I learned that the ability to accept feedback positively is one of the most valuable skills anyone can develop. Feedback Is Not an Attack One of the biggest misconceptions is believing that criticism is an attack on our abilities. When a senior engineer reviews your code and suggests improvements, they are not saying you're a bad developer. When a recruiter rejects your resume, they are not saying you're incapable. When users report problems in your open-source project, they are not trying to discourage you. Most of the time, people are simply showing you where improvements can be made. The sooner we separate our ego from our work, the faster we grow. Every Rejection Contains Information Many professionals view rejection as failure. I view it differently now. A rejection is data. If ten companies reject the same resume, the market is telling you something. If users consistently struggle with a feature, they're revealing a usability problem. If interviewers repeatedly point out the same weakness, they're highlighting a skill gap. The goal isn't to feel bad about the feedback. The goal is to learn from the information hidden inside it. Growth Begins Where Comfort Ends Positive feedback feels good. Constructive feedback creates growth. Nobody enjoys hearing that their architecture can be improved, their communication needs work, or their project has flaws. But those uncomfortable conversations often lead to th

Recently, while working on an in-progress open-source framework called Projector, I ran into a (not particularly novel) issue: one of it's internal packages ( core ) had grown during this period, and was not nearly as flyweight as it needed to be in the browser. The result was 10-20kbs of unnecessary machinery getting pulled in. I noticed this while running examples. I was consistently hitting a wall in bundle sizes that was surprisingly difficult to get past, even for someone as stubborn and relentless as I am. Naturally, I turned to Claude and ChatGPT to help me with this, and ended up using ChatGPT 5.5 with Codex as I find that, with the "precise" output mode, it tends to be a little more honest than Opus 4.8 these days. I shared exported HAR network logs with it, having it go through the chunks to confirm where the bulk was; consistently, it confirmed that the issue was around an entangling of authoring/resolution code with runtime code in core that was pulling in too much to the browser. The technical details here aren't really important, but I'm using them to illustrate a larger point. We then iterated through a lot of different solutions—I setup a "goal" in codex with benchmarks to hit, and gave it a bunch of constraints, context, and tooling. Finally, after about 2-3 hours of looping against that goal, it completed. Looking through the git diff, I noticed something odd—it had duplicated the result of the resolved module, so it could skip the resolution machinery and thus drop it from the browser bundle (again, technical details not really relevant). It hit the rough kb benchmarks, respected all constraints, utilized all context and skills available, and avoided importing the machinery that we both aligned on being the core problem. It provided an elegant, coherent, well-written api, implemented a surgical, well-tested, well-designed solution, and convincingly defended its work when I queried about the implementation. That sounds great, right? In fact, I thin

I’ve been a software engineer for more than 12 years. And like many developers, I’ve been watching AI improve at an incredible speed. Every new model seems smarter than the one before it. Tasks that used to take hours can now be done in minutes. Problems that required deep research can often be solved with a simple prompt. A few years ago, we used to say: Think of AI as a junior developer. That made sense at the time. But today, I don’t think that’s true anymore. AI still makes mistakes. Sometimes very obvious ones. But it also comes up with solutions that surprise me. Sometimes it finds an approach I wouldn’t have thought of immediately. Sometimes it helps me solve a problem much faster than I could on my own. And honestly, that’s both exciting and a little scary. But the biggest thing AI changed wasn’t how I write software. It changed how I think about my work. For most of my career, I thought I loved writing code. I spent years doing it. At work, on side projects, and whenever I had free time. Then AI became part of my daily workflow. In the last month, I’ve built more projects than I normally would in an entire year. Ideas that had been sitting in my notes for years suddenly became possible. And that’s when I realized something important: I don’t actually love writing code. I love building things. I love taking an idea and turning it into something real. I love creating products, solving problems, and seeing something that only existed in my head become something people can use. Code was simply the tool I used to do that. And now AI is another tool. That’s why I don’t hate it. In many ways, AI has helped me build more than ever before. It helped me revisit old ideas that I never had time to work on. It helped me experiment faster. It even encouraged me to explore areas outside software development, like animation and content creation. And this isn’t just happening to programmers. AI is changing design. It’s changing writing. It’s changing marketing. It’s changin

When you talk to ChatGPT about a subject you understand well, you quickly notice something. The first answer is rarely the final answer. You add context. You correct an assumption. You explain what has already been tried. You point out that one proposed solution conflicts with another part of the system. After a few iterations, the answer becomes useful. The same thing happens when AI writes code for real products. The difference is that a slightly incorrect explanation in a chat is usually harmless. Slightly incorrect code can become part of your product, pass a superficial review, and remain there for years. This is why successful AI adoption in software engineering is not primarily about generating more code. It is about context engineering : giving AI enough context, constraints, and feedback to generate code that belongs in your system. The First Answer Is Usually Not Enough AI coding tools are very good at producing plausible solutions. That word matters: plausible. The code may compile. The tests may pass. The implementation may even look clean when reviewed in isolation. But software does not exist in isolation. A change must fit the broader system architecture : the current architecture existing domain rules security requirements operational constraints established conventions previous technical decisions future product direction An AI assistant does not automatically understand those things. It knows the code it can see and the engineering context you provide. Everything outside that window must be inferred. And inference is where divergence begins. If you trust the first response without validating its assumptions, you are usually not accelerating engineering. You are accelerating uncertainty. Lack of Context Creates Duplication One of the first visible effects is duplication. AI does not necessarily know that your application already has: a validation helper for the same domain rule an established authorization pattern a shared API client a retry mechani

One of the oldest axioms of software engineering is that code is written primarily for humans to read, and only secondarily for machines to execute. Clean code, expressive variable names, and architectural elegance all serve a single purpose: to ensure that the next developer - or our six-months-older self - can understand what on earth happened. Code has always been a cultural artifact, a shared language, a bridge between human intent and silicon. But what happens to this bridge in the era of vibe coding? We are rapidly moving toward a reality where code is generated by LLMs and pull requests are reviewed by LLMs. When the resulting string of characters is spawned by a machine and audited by a machine, human readability immediately ceases to be a primary metric of quality. This forces a radical question upon us: If code no longer needs to be human, does the code itself need to change? Why do we still cling to Python, to micro-frontends, or to neatly structured repositories? We invented these structures to accommodate the cognitive limitations of the human brain - to keep ourselves from drowning in complexity. An AI doesn’t need these training wheels. To an LLM, a 50,000-line monolithic spaghetti-code mess, completely impenetrable to a human eye, is just as easy to parse as the most pristine clean architecture. So, what is the point of the code itself? Is it possible that code is merely a transitional, obsolete interface—a form of "digital carbon monoxide" that we will soon phase out entirely, replacing it with pure intent and mathematical weights? I ran this exact thought experiment in practice recently when I built a tiny, native macOS utility called Portia over a single weekend (you can check it out here: getportia.app ). The app's function is dead simple: when a port gets stuck (EADDRINUSE), it frees it up with a single click. Throughout development, I was almost exclusively in vibe coding mode. I wasn’t thinking about syntax; I was thinking about the problem an
