How I stopped nodding along and actually contributed to open source

For years I saw "open source contributions" on job descriptions and just... nodded along. Typed it into Google once, got overwhelmed, closed the tab. It always seemed like something other people did. People who actually knew what they were doing. People who weren't me. Then I started looking into it properly. And honestly? It still seemed big. Like I'd need to understand an entire codebase, find a complex bug, write some genius fix that the maintainers would applaud. Turns out that's not it at all. I found some resources that changed how I saw it completely. The bar to start is embarrassingly low, and that's intentional. The open source community built it that way on purpose. So I did it. Was it a few lines of code? Yes. Did I do it directly in the browser like a person who has no idea what they're doing? Also yes. Do I care? Absolutely not. Where to actually start: goodfirstissue.dev — filters repos by good first issue label up-for-grabs.net — same idea, different interface Docs you already use — if you read something and think "that's oddly worded," you're already there GitHub search — label:"good first issue" is:open and filter by language Here's the thing though, this isn't just about open source. Everything seems big and intimidating at first. So you start small. One tiny contribution. Not because it's impressive but because it's real, and it's yours, and it builds something. Confidence mostly. Then you do a slightly bigger thing. Then a bigger thing after that. You don't level up by waiting until you're ready. You level up by starting small and not stopping. My first contribution exists now. That's enough for today.

Scoring a Page's Meta Tags 0-100: The Rubric Behind Our Analyzer

A meta tag audit is a pile of binary checks. Title present, yes or no. Title in range, yes or no. Description present. One H1. og:image set. Canonical present. Run them all and you get a few dozen booleans. The problem is that a wall of green and red checkmarks does not motivate anyone. People glance at it, feel vaguely bad, and close the tab. A single number does motivate. "You are at 62" is a thing a person will act on. But a number only works if it is honest, and a number is only honest if it is explainable. So we set one hard constraint before writing any scoring code: every point a page loses has to trace back to a named check with a specific fix. No mystery deductions. If you are at 62 and not 100, the tool can point at the exact items that cost you the other 38. That constraint shaped every decision that followed, and it is the reason the rubric looks the way it does. This is the write-up of how we got from a pile of booleans to a number we are willing to defend. Choosing the dimensions and the weights The first decision was how to group the checks. We landed on five dimensions, each with a fixed weight, and the overall score is their weighted average: Basic meta, 30 percent. Title tag and meta description. Headings, 20 percent. H1 count and heading-level hierarchy. Open Graph, 20 percent. og:title, og:description, og:image, og:url. Twitter Card, 15 percent. twitter:card, twitter:title, twitter:description, twitter:image. Technical, 15 percent. Canonical, html lang, viewport, robots. The weights are the opinionated part, and they encode what we actually believe about how pages get found now. Basic meta gets 30 percent, the largest slice, because the title and description are the strings an AI engine quotes when it summarizes or cites a page. They are the highest-value characters on the whole page, so a gap there should cost the most. Technical gets the smallest slice at 15 percent, but for a subtler reason than "it matters least." Technical failures are rarer

My web app fired two POST requests per submit. The fix taught me what React StrictMode is actually for.

We run an app where you describe a task and an AI agent does it. The first step after you hit submit is a planning call: POST /api/web/tasks/plan, which turns your free text into a structured plan the agents can pick up. One submit should mean one plan. While testing locally I noticed two plan requests going out per submit. Same payload, fired back to back. The agents handled it fine because the second plan just overwrote the first, but it bothered me. A doubled write is a doubled write, and the next one might not be idempotent. First wrong guess: a double-click My first assumption was the obvious one. The user double-clicks, or the button is not disabled during the request, so two clicks sneak through. I added the disabled state, watched the network tab, and got two requests from a single click. So it was not the button. The thing I had stopped seeing The submit logic lived in an effect. When the form phase flipped to submitting, the effect ran and fired the plan call. There was a second effect too: when the user changed the tier or output format mid-flow, a matching effect re-planned, because a different tier means a different plan. Neither effect had any guard against running twice. And in development, React StrictMode mounts every component, unmounts it, and mounts it again, on purpose, to surface effects that are not safe to re-run. My plan effect was exactly the kind of effect StrictMode is built to expose. The double mount fired it twice. The detail that made it click: I built the app for production and watched the network tab there. Exactly one request. The double was a development-only artifact of StrictMode doing its job. The bug was never in production traffic, but the fact that StrictMode could double it meant my effect was not safe, and an unsafe effect is a latent bug waiting for a real remount. The fix: ref guards set before the await, not reset in cleanup The instinct is to reach for a boolean. The catch is where you reset it. If you reset the guard

Understanding Java Constructors and Inheritance Through Simple Real-World Analogies

Hey Folks! 👋 Good Day... This blog is a summary of the concepts covered during the last two classes at my institute. One of the reasons I enjoy writing these blogs is that they serve as my personal knowledge journal. Whenever I need a quick refresher on a concept, I can simply revisit my blog instead of searching through notes or recordings. It helps me reinforce what I've learned while also documenting my learning journey. Over the past two days, we explored several important Java concepts, including constructors, the this keyword, inheritance, constructor chaining. In this blog, I'll share what I learned in the simplest way possible, using real-world analogies, practical examples, and the thought process that helped me understand these concepts more clearly. If you're a beginner learning Java, I hope this walkthrough makes these topics a little easier to grasp and a lot more memorable. What Is a Constructor? According to Oracle Java Documentation: A constructor is a special method that is used to initialize objects. The constructor is called when an object of a class is created. In simple terms: Imagine you order a new smartphone. Before the phone reaches your hands, the factory installs the operating system, configures the hardware, and prepares everything for use. A constructor does exactly the same thing for an object. Before you use an object, Java uses the constructor to prepare it. My First Confusing Example I wrote the following code: public class SuperMarket { String name = "python" ; int price ; public SuperMarket ( String name , int price ) { System . out . println ( "Are you constructor?" ); name = name ; price = price ; } public static void main ( String [] args ) { SuperMarket product1 = new SuperMarket ( "abc" , 20 ); System . out . println ( product1 . name ); } } I expected the output to be: abc But Java printed: python And honestly... I was completely confused. After all, I passed "abc" into the constructor. Why was Java ignoring it? The Hotel Roo

Wordpress 7.0 completely broke keyboard navigation in the block editor

I don’t know if the adoption of 7.0 is just too low for this to become widespread or if I’m just a weirdo and most people don’t use their arrow keys to navigate the editor but this used to work perfectly and is now completely broken. Before 7.0 if you had a set of nested blocks, let’s say a group block with columns and then heading, paragraphs, images etc in the individual columns, you could use your arrow keys to move through the layers. For example if I was in the heading tag at the top of a column and clicked the up arrow it would make the column block the active selected block. Press it again and you’re on the columns container. One more time and you’re at your parent group. Now if I’m in that exact same scenario and click up from the heading block it will jump me to the lowest nested child block of the next highest root level block or if I’m already in the highest root level block it will take me to the page title. There is absolutely no way to use the keyboard to navigate between layout block layers anymore and it’s infuriating. This functionality is so engrained into my brain that it’s muscle memory at this point and I keep flying all over the page when I just want to adjust my column gaps or something. Forcing me to point and click around to the breadcrumbs or expanding the document overview sidebar is such a pain and takes so many steps. I have to imagine this is also absolutely horrible for accessibility, not being able to even get to certain blocks without a mouse. I just have no clue why they would change something that was so logical and just worked exactly as expected since the inception of the block editor. Was this just a mistake or did someone intentionally do something this stupid? I truly can’t see any value to how the keyboard navigation works now and see no point in why someone would choose for it to behave this way over the old way. Is there something I’m missing? Am I just a stubborn old developer who hates change? I feel like this is not unre

Laravel API data envelope

i'm having a hard time deciding which approach i should implement. i'm developing a Laravel api which is consumed by Vue & Nuxt and i didn't noticed that i actually implemented two approaches of the returned response: [1] return ArticleResource::collection($articles); this returns a JSON like this: { "id": 1, "title": "My Article" } [2] return response()->json([ 'data' => new ArticleResource($article), 'success' => true, 'message' => 'OK', ]); JSON: { "data": { // output of ArticleResource transformed $article }, "success": true, "message": "OK" } considering that the API and frontend are private repositories. does wrapping all of the response inside 'data' makes sense or should i just stick on [1] for less nesting? what do you guys think what do you usually do with your years of experience? submitted by /u/Totoro-Caelum [link] [留言]

Do you think Generative UI is the new Frontend?

Yesterday, I read a blog by Shubham on how Generative UI is changing entire frontend space. The frontend has always been something you build ahead of time and ship. The agent just works inside it. For 30 years that was the deal. What's actually shifting: the interfaces shipping in 2026 are drawn partly by the agent itself, in real time, from what the user actually asked for. He breaks down the different approaches (A2UI, MCP Apps, AG-UI) via CopilotKit and where each one actually falls apart depending on how deep in the app you go.. along with the token tax - how typical tool description with its JSON schema runs around 400 tokens. 25 components are 10,000 tokens on every turn, you pay that tax per request. worth a read especially the declarative generative UI pattern where you hand the agent a catalog and let it assemble layouts you didn't pre-build. blog link: https://x.com/Saboo_Shubham_/status/2062220865643982875 repo: https://github.com/CopilotKit/copilotkit do you think it's just marketing hype or actually the future of UI? submitted by /u/allenaa3 [link] [留言]

Agentic AI in software development: what's actually production-ready in 2026

Agentic AI in software development: what's actually production-ready in 2025 There's a lot of noise about AI agents right now. This post is an attempt to be precise: what is an agent architecturally, what can it actually do in a dev workflow today, and where does it still break. **What makes something an "agent" vs. a standard LLM call **A standard LLM call is stateless. You send a prompt, you get a response. No memory of previous turns (unless you manage it yourself), no external actions, no loop. An agent is a system built around an LLM that adds: Persistent memory across steps in a task Tool use - structured access to external systems (file I/O, shell execution, HTTP calls, database queries) A planning + evaluation loop - the agent generates a plan, executes a step, checks whether it succeeded, and decides next action Without all three, you don't have an agent. You have a capable model with maybe some extra context. What's actually production-ready today High confidence (use in production): Unit test generation for existing, well-documented code Boilerplate scaffolding (new modules, new endpoints, CRUD patterns) Documentation generation tied to code diffs Code migration tasks (framework upgrades, Python 2→3, ORMs) PR description generation from diffs Bug triage: given an issue, find likely affected files * Works but needs oversight: * Multi-file refactoring Dependency updates with breaking changes Writing integration tests (more surface area for wrong assumptions) Not there yet: Novel architecture decisions Debugging in unfamiliar/undocumented codebases Tasks with genuinely ambiguous requirements Long autonomous chains (>10 steps) without human checkpoints The failure modes to build around Ambiguous task specification Agents optimize for completing the task as specified. If the spec is loose, they'll complete the wrong task confidently. Be more precise with agents than you'd be with a junior engineer - there's no informal Slack thread to resolve ambiguity. Error

How I Built Pakistan's Stock Market Education Platform as a Solo Trader-Developer

I am a full time trader and part time developer based in Karachi, Pakistan. A year ago I sat down to research how to properly compare brokers on the Pakistan Stock Exchange. Three hours later I had 11 browser tabs open, two of which had broken links, one had data from 2019, and none of them had everything I needed in one place. So I built PSX Pulse. What PSX Pulse Is PSX Pulse is a free stock market education platform for Pakistani retail investors. Everything a beginner needs to start investing in Pakistan's stock market — in one place. What is live right now: 35 verified SECP-licensed brokers with full contact details Complete mutual funds directory across 15 AMCs DCA calculator with realistic return scenarios 30-day beginner learning path Islamic investing guide PSX sector guide covering 12 sectors IPO tracker 100-term searchable glossary Weekly market recap every Friday All free. No login required. Live at: https://psxpulse.xwen.com.pk/ The Stack React + Tailwind CSS for the frontend. Vercel for hosting — free tier handles everything comfortably. No backend for most features — localStorage and static data keeps it fast and simple. Newsletter handled via a serverless Vercel function writing to a private GitHub CSV. What I Learned Building This Solo 1. The information gap in emerging markets is enormous Pakistani investors are not underserved because nobody cares. They are underserved because nobody with the technical skills to build tools also has the market knowledge to know what those tools should do. Being both a trader and a developer turned out to be the actual unfair advantage. 2. Free tools beat content for SEO My DCA calculator and broker directory pages get more consistent Google clicks than any article I have written. Tools solve a specific search intent that AI overviews do not replace — people still need to interact with a calculator, not just read about one. 3. Building in public is uncomfortable but worth it Sharing what you are building before it i

How I built a lightning-fast Game Sens Converter in Vanilla JS

As a developer who frequently switches between competitive FPS titles like CS2 and Valorant, re-tuning mouse sensitivity is always a hassle. I wanted a fast, ad-free tool to translate my aim perfectly across titles, so I built a clean Game Sens Converter . The Approach I built this using 100% Vanilla JS. It’s a simple utility, so there was absolutely no need for a backend or heavy frameworks. It loads instantly and calculates right in the browser. Here is a quick look at the core logic handling the sensitivity conversion multipliers: function convertSensitivity ( gameFrom , gameTo , currentSens ) { // Standardized multipliers relative to CS2 / Source engine const multipliers = { ' cs2 ' : 1 , ' valorant ' : 3.181818 , ' overwatch ' : 0.3 , ' apex ' : 1 }; if ( ! multipliers [ gameFrom ] || ! multipliers [ gameTo ]) return null ; // Convert to base (CS2), then to the target game const baseSens = currentSens * multipliers [ gameFrom ]; const convertedSens = baseSens / multipliers [ gameTo ]; return convertedSens . toFixed ( 3 ); } Try it out You can use the live tool for free here: Game Sens Converter Let me know what your main game is or if you'd add any other FPS titles to the list in the comments!

Provide private storage for internal company documents

Create a storage account and configure high availability. Create a storage account for the internal private company documents. In the portal, search for and select Storage accounts . Select + Create . Select the Resource group created in the previous lab. Set the Storage account name to private . Add an identifier to the name to ensure the name is unique. Select Review , and then Create the storage account. Wait for the storage account to deploy, and then select Go to resource . This storage requires high availability if there’s a regional outage. Read access in the secondary region is not required. Configure the appropriate level of redundancy . Explanation A storage account is like a digital locker in the cloud. Resource group is a folder that organizes related services. High availability means your files stay safe even if one region (data center area) has problems Configure Redundancy In the storage account, in the Data management section, select the Redundancy blade . Ensure Geo-redundant storage (GRS) is selected. **Refresh **the page. Review the primary and secondary location information. Save your changes. Explanation : Redundancy means keeping copies of your files in multiple places. GRS ensures your files are copied to another region for safety. Create a storage container, upload a file, and restrict access to the file. Create a private storage container for the corporate data. In the storage account, in the Data storage section, select the Containers blade. Select + Container . Ensure the Name of the container is private . Ensure the Public access level is Private (no anonymous access). As you have time, review the Advanced settings, but take the defaults. It means: don’t change anything in the Advanced settings unless the lab specifically tells you to. Azure already chooses safe, recommended defaults for you. Select Create . Explanation : A container is like a folder inside your storage account. Setting Public access level to Private means nobody can see

Kubernetes vs Docker (2026): What's the Difference and Which Should You Learn First?

📌 This article was originally published on Sherdil E-Learning . I'm republishing it here so the dev.to community can benefit too. The Kubernetes vs Docker question is one of the most common sources of confusion for developers entering DevOps. People hear both names constantly, see them used together in job listings, and assume they must be competitors. They are not. Docker and Kubernetes do different jobs, and most modern infrastructure uses both. This guide explains what each tool actually does, how they fit together in a real deployment, the practical difference between Docker Compose and Kubernetes, and which one you should learn first. Docker: the container creator Docker is a tool for building, running, and managing containers . A container is a lightweight, portable package that contains an application together with its dependencies, runtime, system libraries, environment variables, and configuration files. The same container runs the same way on a laptop, a CI runner, a production server, or a cloud platform. In a typical Docker workflow you: Write a Dockerfile that describes how to build the image Run docker build to produce the image Run docker run to launch a container from it For multiple containers (a web app plus a database, for example), you use Docker Compose to define the whole set in a docker-compose.yml file and start them with one command. Docker is excellent for individual containers and small multi-container applications. The limitation is scale. What happens when you need a hundred containers across a dozen servers? When one container crashes at 3 a.m.? When you need to roll out a new version without downtime? Docker alone does not solve those problems. For the official reference, see docs.docker.com . Kubernetes: the orchestration layer above Docker Kubernetes (often shortened to K8s ) is an open-source platform that runs containers across many machines as a single coordinated system . It was originally built at Google, based on their internal

How a Culture of Data-Driven Conversations Can Support Platform Engineering

To provide SRE as a service, a team built a center of excellence, introducing Federated SREs and roles like production manager and technical tribe lead. They created a culture of data-driven conversations where SLOs and SLAs were democratised. Surviving growing cognitive load meant continuously simplifying architecture and embedding sovereignty and resilience into platform design decisions. By Ben Linders
