I spent 13 years in financial services — 7 at Discover Financial, 6 at Bread Financial — consistently finishing in the top 5% of my team. I was good at my job. Really good. But in March 2026, I enrolled in Coding Temple's Full-Stack Web Development bootcamp and started building. Here's what 3 months actually looks like from zero. Month 1: HTML, CSS, and Figuring Out Why Nothing Looks Right I started where everyone starts — HTML and CSS. Built a food landing page (FoodSpot) and a multi-page event site (EventHive). Learned Flexbox, Grid, responsive design, and why box-sizing: border-box should just be the default everywhere. What I shipped: FoodSpot — food landing page EventHive — responsive multi-page event site What I earned: ✅ Web Development with HTML & CSS (Coding Temple verified badge) Month 2: JavaScript, Then Python JavaScript clicked faster than I expected. DOM manipulation, ES6+, event listeners. Then Python — and honestly, Python felt natural. The OOP concepts made sense immediately. What I shipped: Python CLI Task Manager — persistent task app with file storage, OOP, exception handling Defeat the Evil Wizard — text-based RPG with multiple classes, inheritance, combat logic, and game state management What I earned: ✅ JavaScript Mastery ✅ Python Foundations for Software Engineering ✅ Advanced Python Month 3: React React was the biggest jump. Component architecture, hooks, state management, routing. But I got through it by building something real. What I shipped: FakeStore API — a full e-commerce SPA consuming a live REST API with dynamic product rendering, client-side routing, CRUD operations, and loading/error state management What I earned: ✅ Single Page Apps with React What I Brought From Finance That Helped People underestimate what non-tech backgrounds bring to code. Here's what transferred directly: Data analysis → Debugging mindset. I spent years finding patterns in account data. Finding why code breaks is the same muscle. Process optimization → Clean

We tend to write React as functional programming because the functional component is the mainstream. In this era, one of the issues we often encounter is conditional statements. There are a variety of conditional statements, such as if, switch, and ternary operator. We confuse when to use them properly. Assign the result of the conditional statement into a variable This makes it easy to read, test, and modify codebases. The representative case is ternary operator const userName = user ? user . name : ' No user found ' ; Of course, we can write the code another way. const point = 80 ; let result ; if ( point >= 70 ) { result = ' passed ' ; } else { result = ' failed ' ; } console . log ( result ); // passed In this way, we can not ensure the immutability of let , and this section with the conditional branch is written in a procedural style. To solve this issue, we have to wrap this in a function. const judge = ( point : number ) => { if ( point >= 70 ) { return ' passed ' ; } return ' failed ' ; }; In addition to wrapping that statement, I suggest that you use early return to save the else statement. Do not write conditional statements in the return value of tsx (the UI rendering portion) ** When there is only a single conditional statement, or there is no need for any execution in the conditional statement. Let's use the ternary operation simply. import { FC } from ' react ' ; import { useQuery } from ' @tanstack/react-query ' ; import getUser from ' domains/getUser ' ; type Props = { userId : number ; }; const Profile : FC < Props > = ( props ) => { const { userId } = props ; const getSpecificUser = async () => { const specificUser = await getUser ( userId ); return specificUser ; }; const { data : user } = useQuery ([ ' user ' , userId ], getSpecificUser ); const userName = user ? user . name : ' User not found ' ; return < p > User ： { userName } < /p> ; }; export default Profile ; const userName = user ? user . name : ' User not found ' ; In this statement, you

The code runs. That's not the question. There's a failure mode with AI-generated code...

After months of building in public, is live on Product Hunt today! 🎉 The problem Every dev team I've worked with ends up in the same trap: Jira is too heavy and slows everyone down with ceremony, while Trello/Notion are too light and can't actually tell you if your sprint is on track. Nobody had a tool that combined real project management with AI that actually understands developer workflows. So I built one. What is Rahnuma.io? Rahnuma.io is an AI-powered DevOps platform that sits where project management meets your actual engineering workflow: 🧠 AI task generation — describe a feature in plain English, get a structured task with subtasks 📊 Deadline risk forecasting — a live risk score (0–100) built from time risk, blockers, and completion rate, so you know a sprint is in trouble before it blows up 🗂️ Kanban + sprints — drag-and-drop boards, WIP limits, burndown charts, story points 🤖 AI sprint retros — auto-generated "what went well / what didn't / action items" 🔗 GitHub & Bitbucket integration — see commits next to the tasks they belong to 📈 Reports that don't require a translator — including an "Explain to My Boss" button that turns your sprint into a plain-English executive summary 🔔 Slack notifications for task creation, assignment, and comments 🧾 Client portals — shareable, printable progress reports for non-technical stakeholders Why it's different Most "AI project management" tools just bolt a chatbot onto a Trello clone. AI is wired directly into the data model — it knows your sprint history, your velocity, your blockers — so the forecasts and summaries are grounded in your actual project state, not a generic prompt. Tech under the hood Next.js 15 (Turbopack) · TypeScript · Prisma + PostgreSQL · Clerk auth · Polar billing · Redis · xAI Grok with Groq fallback for AI · Server-Sent Events for realtime sync. Try it It's free to start, no credit card required. I'd love your feedback — especially from anyone who's felt the Jira-is-too-much / Trello-is-too-littl

The whole industry seems to have agreed on a standard for design tokens. The shift it sets up is still on its way. Design tokens are not new. The term was coined in 2014, at Salesforce, by Jina Anne and Jon Levine. 1 By 2017, Amazon had open-sourced Style Dictionary and the idea had spread well past Salesforce. We have been shipping design tokens for over a decade. What we never did, in all that time, was agree on a format. Every tool and every team rolled its own shape. There was never one neutral way to write a token down, its value and its meaning, so that any other tool could read it. Have you heard of DTCG? I hadn't, until recently. It is the Design Tokens Community Group, a W3C effort to finally settle that format. 2 The repo is quiet, but that is because the spec reached its first stable version in late 2025, not because anyone walked away. The quiet is a thing being finished, not abandoned. The list of who is backing it is not quiet at all. Adobe. Google. Microsoft. Meta. Amazon. Shopify. Salesforce. Sony. Pinterest. The New York Times. Disney. Framer. Penpot. Figma. Plus a dozen more. 2 That is not a side project. That is most of the industry quietly agreeing on something. One of those names, Figma , is the reason for the title of this piece. We will get to it, because the irony is the whole point. Here is my bet, and I will say up front that it is a bet. I think a storm is coming for design tooling. You do not have to believe me about the storm, because the bet does not depend on it. If you are wiring your tokens straight into one vendor's format, you are exposed. Anchor them to the open standard instead and you are not. The downside is lopsided. If I am wrong, you have lost almost nothing. If I am even half right, everyone hard-coded to a single tool is facing a rewrite. The format is young and already fragmenting. That is the point. The obvious objection is that the standard is too new to bet on, and already splintering. It is splintering. Google's DESIG

Creating Short Links with PHP: A Practical Guide URL shorteners are everywhere. They're used in marketing campaigns, email newsletters, QR codes, social media posts, affiliate links, and analytics platforms. While most developers are familiar with services like Bitly, integrating a URL shortener directly into your application is often much more useful. In this article, we'll build short links from PHP using an API. Why Create Short Links Programmatically? Creating links through a dashboard works for occasional usage. But applications often need to generate links automatically. Common examples include: Email campaigns User invitations Affiliate systems QR code generation Marketing automation Analytics tracking Customer portals An API allows applications to create and manage links without human interaction. The Traditional HTTP Approach Most URL shortener APIs work through simple HTTP requests. For example: $client = new GuzzleHttp\Client (); $response = $client -> post ( 'https://example.com/api/links' , [ 'headers' => [ 'X-Api-Key' => $apiKey , 'Content-Type' => 'application/json' , ], 'json' => [ 'url' => 'https://example.com/article' ] ] ); $data = json_decode ( $response -> getBody (), true ); echo $data [ 'short_url' ]; This works. But once your application creates dozens or hundreds of links, the amount of boilerplate code starts growing. Using a PHP SDK A PHP SDK removes most of the repetitive work. Installation is usually straightforward: composer require lix-url/php-sdk Creating a link becomes much simpler: $link = $client -> links () -> create ([ 'url' => 'https://example.com/article' ]); echo $link -> shortUrl ; The SDK handles: Authentication HTTP requests Response parsing Error handling DTO mapping This allows your application code to remain clean. Creating Your First Short Link Let's imagine an application that sends invitation emails. $inviteLink = $client -> links () -> create ([ 'url' => 'https://myapp.com/invite/abc123' ]); echo $inviteLink -> short

This is a complete, copy‑pasteable guide for shipping a backend app to a single Linux server using Docker Compose , with a GitHub Actions pipeline that builds the image, scans it, and deploys it over SSH. It is written to be language- and framework-agnostic . The examples use a Node/TypeScript API with PostgreSQL, Redis, and a background worker, but the same shape works for Python/Django, Go, Java/Spring, Ruby, etc. Anywhere you see your-app , your-org , your-server-ip , or example.com , substitute your own values. Every file is included in full, and every non-obvious line is explained. The last section — Common errors and how to fix them — is the part most guides skip, and it is the part that will actually save your afternoon. All of it comes from a real deployment, mistakes included. 1. The mental model (read this first) Before any YAML, understand the shape of what we're building. There are only three places anything lives: Your Git repository the single source of truth. Your code, your Dockerfile , your docker-compose.prod.yml , and your CI/CD workflows all live here. You only ever edit things here. A container registry (we use GHCR, GitHub's built-in registry) — a warehouse for the built application image. CI builds the image and pushes it here. Your server (a plain Linux VPS) pulls the image from the registry and runs it. It holds exactly two files: the compose file (copied from your repo by the pipeline) and a secrets file ( .env ) that never leaves the server. The flow, end to end: You push to main │ ▼ GitHub Actions: build image ──► push to registry ──► scan image │ ▼ GitHub Actions: SSH to server ──► pull image ──► run migrations ──► start app ──► health-check The single most important rule: the server is disposable . You never hand-edit files on the server, because the pipeline overwrites them from the repo on every deploy. If you fix something by editing on the server, the next deploy silently erases your fix. Edit in the repo, commit, push. (I learned t

We talk a lot about what AI can build. Code generation. Faster prototypes. Automated debugging. One-shot apps. Entire products created in hours. And yes, AI is powerful. But there is a quieter cost we are not talking about enough: AI hype is starting to weaken the motivation to learn core engineering deeply. That should worry us. 1. The "Why Bother?" Mindset When the dominant narrative says AI can generate code instantly, many engineers start asking: Why should I spend months mastering frameworks, architecture, databases, networking, or system design? At first, that sounds practical. If a tool can help, why not use it? But there is a difference between using AI to move faster and using AI to avoid understanding. Core engineering is not just about writing code. It is about knowing why something works, where it breaks, how it scales, and how to fix it when the generated answer is wrong. If we skip that learning, we create engineers who can prompt systems but cannot reason deeply about systems. That is a dangerous tradeoff. 2. The Funding and Praise Monopoly Right now, AI gets most of the attention. Budgets move toward AI. Leadership praises AI initiatives. Teams are pushed to add AI features even when the fundamentals are still weak. Meanwhile, excellent core engineering often goes unnoticed. The people improving reliability, performance, developer experience, infrastructure, security, and maintainability are still doing high-impact work. But in many places, that work is being treated as less exciting simply because it is not branded as AI. This creates pressure. Engineers feel they must pivot to AI, not always out of interest, but out of fear. Fear of being left behind. Fear of being replaced. Fear that their existing expertise is no longer valued. That is not innovation. That is anxiety disguised as progress. 3. The "AI-First" Discount There is another subtle problem. When someone builds something impressive today, the reaction is often: AI probably generated that.

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built Some time ago, I needed to calculate hashes of directory trees across multiple platforms and architectures. Many existing solutions were based on GNU find, but I quickly realized that this approach has a number of shortcomings. As a result, hashdir was born: a cross-platform tool that takes into account many of the quirks and edge cases involved in calculating directory hashes, including character encoding, path separators, path overlaps, symlinks, and more. For use cases involving directory structures that contain very large binary files, I also added support for the imohash algorithm, which can hash large files quickly while maintaining an acceptable error rate. Once it had solved my original problem, I decided to share it with the world. Demo A short demo, along with installation and usage instructions can be found in the repository . The Comeback Story To my pleasant surprise, people began engaging with hashdir in various ways. One user reached out to tell me they were using it in their work and requested additional features, while another packaged it for their own use. Their interest motivated me to expand the feature set, improve test coverage and continuous integration, and further strengthen the codebase's robustness and overall quality.

Code generation tools are powerful and can significantly accelerate development work. Their main limitation is not capability, but context. Without access to organizational knowledge, internal conventions, and system-specific patterns, generated output often requires careful verification. This is why generation tools work best when paired with AI code search, as the latter provides immediate visibility into the existing codebase, making it easier to align AI-generated changes with the realities of the system. In regulated environments, the adoption model may look different. Security or compliance constraints can restrict the use of cloud-based code generation. AI code search still improves developer efficiency across implementation, review, and documentation workflows by enabling fast navigation and comprehension of large multi-repository codebases. What is AI code intelligence, and how does it help in practice? Code intelligence tools help developers find and understand existing code. If a search returns a poor result, the developer simply searches again. Nothing changes in your codebase. Code search also integrates without friction. No new review processes, no changes to CI/CD, no new permissions. Generation tools require policies for AI-written code that stall many pilots before they produce data. Clear metrics for measuring AI code intelligence An AI code search assistant only reads your code, which makes it much easier to measure its impact. You can track simple things like: • how long it takes to find the right piece of code • how quickly new developers get up to speed • how many hours the team spends searching each week If your team of 20 developers each spends 5 hours weekly understanding code, that equals 100 hours of engineering time. At $75 per hour, that’s $360,000 per year. Assume 10% reduction recovers $36,000, a realistic input for an AI ROI framework for tech teams. Faster path to Phase 3 expansion Code generation tools face tough questions from secu

The agents were doing exactly what I told them to. That was the problem. I'd built a pipeline where AI agents could take a spec file, implement a feature, run the tests, review the result, and commit — without me writing a line of code. It mostly worked. Dozens of features shipped. But I kept reviewing the output and feeling like something was off. Not broken. Just subtly wrong in a way that was hard to name. I spent a while blaming the models. Then the prompts. Then the validation steps. Eventually I had to sit with the obvious: the agents were implementing exactly what I'd written. My specs were underspecified. The bottleneck was always me, at the planning stage. The thing most people throw away There's something that feels right about vibe coding. You're operating at the level of intent — describing what you want and letting the model handle the mechanics. That part is genuinely useful. But watch what most people do with the output: Traditional development: Source code → Compiler → Binary (keep the source; regenerate binary anytime) Vibe coding done wrong: Prompt → LLM → Generated code (delete the prompt; commit the code) You've shredded the source and carefully version-controlled the binary. The prompt — your structured description of what you wanted, why, and what "correct" meant — is the valuable artifact. The generated code is what compiles from it. When you discard the prompt and commit only the output, you've lost the thing that actually mattered. The practical consequence shows up six months later: you're staring at code you wrote and spending twenty minutes reverse-engineering your own intent. The spec would have been a thirty-second read. What a spec-driven pipeline is I built what I call an SDLC (Software Development Lifecycle) harness — a system where instead of writing code directly, you write a spec describing what needs to be built, and AI agents handle the implementation, testing, review, and documentation. The spec is the source. The code is what

A follow-up to Part 1 ( EN on LinkedIn · RU on Habr ), where we stood up a two-tier PKI: a Root CA and three intermediate CAs — Person, Server and Code. At the end of Part 1 I promised we'd learn to revoke certificates and run OCSP. That's what we'll do here. Like Part 1, this article is meant as a hands-on manual : for every command and extension we touch, there's an extended reference of the parameters you can actually use — with syntax, allowed values, defaults and gotchas. If you don't need a given option right now, just skim past the table; it's there so you don't have to dig through man later. Each section has the same shape: first the working commands for the common case, then the full parameter reference. Tested on versions. Flag names, defaults and extension syntax were verified against the official documentation of OpenSSL master , plus nginx and Apache mod_ssl. OpenSSL evolves per branch: anything marked "OpenSSL 4.0 / master" (for example the nonss qualifier on authorityKeyIdentifier ) is not yet available in the stable 3.x line. If you're on OpenSSL 3.0–3.6, double-check the disputed options with openssl <cmd> --help or your version's man before copy-pasting config. The numeric openssl verify error codes above 40 also shifted between branches — confirm them against your version's header. In this part: How a revoked certificate differs from an expired one, and why we need two mechanisms — CRL and OCSP. Adding the distribution points (CDP) and AIA to the config so issued certificates "tell" verifiers where to check them. Revoking a certificate and working with the CA database. Generating a CRL and inspecting it with openssl crl . Checking revocation with openssl verify . Running an OCSP responder: issuing its certificate, starting the daemon, querying status. Publishing the CRL and OCSP over HTTP (nginx), configuring OCSP stapling and revocation checking on the web server. All paths, file names and config sections are the same as in Part 1.
