This is a submission for Weekend Challenge: Passion Edition ❤️ Dedication This project is dedicated to every passionate developer out there grinding on late-night code, and to the incredible DEV Community team for creating a space that fuels our growth every single day. 🚀 What I Built I built DEV Passion Fuel Station —a minimalist, single-page HTML5 web app engineered to protect the fire driving our late-night side projects and hackathon builds. Developers can vent, drop logs, or copy-paste messy code frustrations directly into the interface. The system leverages the Gemini 1.5 Flash API to dynamically gauge developer sentiment, analyze burnout metrics, and return actionable, bite-sized tasks to keep project momentum going without overwhelming the builder. 🔗 Demo You can try the live web app directly in your browser here: 👉 https://projects-of-passion.netlify.app 💡 Journey & Inspiration As a beginner coder, diving into an AI hackathon was intimidating but incredibly exciting! Passion is the primary catalyst behind the DEV Community—we see it every day in the deep dives and side projects shared here. However, relentless passion often dances right on the edge of burnout. I wanted to build something exclusively tailored to our community: a safe space to dump developer blockages and get practical, AI-supported next steps to keep our engines running smoothly. 🛠️ Technical Execution The application targets the Best use of Google AI prize category. Frontend: A single-file HTML5 interface styled with an energetic, modern dark-mode DEV aesthetic. Backend Intelligence: Powered by the Gemini 1.5 Flash API using native JavaScript fetch . Hassle-Free Architecture: Since I wanted to keep it light, the entire app runs out of a single file hosted on Netlify . Anyone can paste their own Google AI Studio key directly into the UI to test it safely, keeping personal keys private while allowing judges to grade the app seamlessly.

Publishing ten apps in four months sounds good. And it is good. It means the bottleneck is no longer building the app. With AI-assisted coding, small utilities, focused experiments, and niche apps can go from idea to App Store submission in days, sometimes hours. But there is a second part that can soon get really ugly. And messy. And time consuming. After you publish the apps, you own them – not in the inspirational sense, in the annoying sense. Every app becomes a small surface that needs attention: metadata, screenshots, reviews, ratings, keywords, conversion, cross-promotion, build status, rejections, releases, privacy answers, promo text, support links. Ok, you can catch your breath now. We good? Good, let’s move on. One app is manageable as a pastime, but ten apps are already a small portfolio. And a small portfolio needs systems. So I started building one. The repo is called app-store-release-agent , and, for now, it’s a small Python toolkit for the release workflow itself. Eventually, this could evolve into a full ASO brain. The Business Problem The business problem is simple: maintenance does not scale linearly with motivation. Building an app has a clear dopamine loop. Maintenance is fragmented: a review here, a screenshot there, a keyword set that probably needs work, a support email, a product page that now feels weak. None of these tasks are hard in and by themselves. That is a real and very subtle trap, because they can easily get postponed, and then they pile up. The benefit of an automation pipeline is not only speed. Speed is good, don’t get me wrong, but it’s secondary. The real benefit is lowering the activation energy. If the agent can pull live App Store data, compare it with local metadata, inspect git history, and apply the next release action safely, I do not have to reconstruct the context from scratch every time. A good pipeline should answer three questions quickly: What needs attention now? What can wait? What action has the highest lever

I shipped the first public build of a Chrome extension two weekends ago. The marketing-ready UI took me about six hours. The four state bugs below took me the rest of those two weekends, plus parts of the following week. I am writing this down because every reviewer of "I built an X in Y hours" posts seems to skip the state-model half, and the state-model half is where the actual time goes. The extension A sidebar that lives in Chrome's side panel API. You highlight text or screenshot a region on any page, the sidebar lets you pick a destination AI tab (ChatGPT / Claude / Gemini / a custom one) and forwards the content with a small wrapper prompt. That is the whole product description. The interesting part is what happens when a user does it twice. Bug 1: the destination you "logged into" is not the destination the message lands in First failure I caught: user has two ChatGPT tabs open, one workspace, one personal. The extension forwards to whichever tab was last focused. The user sees the message arrive in the workspace, replies there, then realizes the context they wanted to capture is on the personal tab. Fix: every AI destination registers a stable tab id at extension boot, not at click time. The forwarding logic walks the registry, not the focused window. Took a morning to redesign, an afternoon to migrate existing flows. Lesson: tab identity is not the same as window focus. Chrome's chrome.tabs.query({active: true}) returns the active tab. The active tab is not necessarily the destination the user has in their head. Bug 2: the screenshot is from before the user edited it User takes a screenshot of a code block, opens the sidebar, hits "annotate", drags a red box around lines 12-15, hits send. The annotation worked. But the underlying screenshot bytes were captured at the moment the toolbar first appeared, before the user could draw the box. Fix: the sidebar cannot trust that the screenshot in memory is the screenshot the user is looking at. Either re-capture o

For years, scam prevention has relied on a familiar instruction: educate people so they can recognise danger before they act. Public campaigns warn consumers not to click unexpected links, disclose security codes, transfer money under pressure, or trust unsolicited contact. This advice remains useful, but it places too much defensive responsibility at the final point in a long scam chain. The Australian Scams Prevention Framework, or SPF, reflects a more demanding view. The framework requires selected service providers to take action against scams connected with or using their services. Its governing logic extends across prevention, detection, reporting, disruption, response, governance and intelligence sharing.[1][2] Australia has therefore moved beyond a model in which awareness is treated as the primary control. The emerging standard is an operational system in which institutions must identify scam activity, convert reports into usable intelligence, intervene against infrastructure, assist affected consumers and learn from recurring campaigns. This distinction is important. Awareness changes what a person knows. Operational scam defence changes what a scammer can do. Awareness Operates at the Last Defensible Moment Most awareness controls activate immediately before the victim acts. A warning appears before a transfer, a browser displays a suspicious-site alert, or a public campaign advises the consumer to pause and verify. By that stage, however, the scam may already have passed through several successful phases: The victim has been reached through SMS, email, social media, a search advertisement, a phone call or a marketplace conversation. A trusted brand, institution, employer, government agency or personal identity has been impersonated. The scammer has created urgency, authority, fear, opportunity or emotional dependency. The victim has been moved to a website, app, private chat or phone conversation. Payment, credential, identity or access pressure has begu

This is a submission for the DEV Weekend Challenge: Passion Edition . What I Built Everyone will tell you about the passions they have. Nobody talks about the ones they quit. I played cricket every evening from age 11 to 17. I told everyone I'd play Ranji Trophy one day. Then the entrance exam years came, the bat went behind the cupboard, and I never went back. Eight years now. EMBER gives that abandoned passion a voice. You confess what you quit. AI forges its persona: the dusty object, the game itself, or the younger you. Then it talks back , out loud, in a voice matched to its temperament. It asks the question only it can ask: why did you really stop? Then it offers two doors: 🔥 Rekindle it. It negotiates the smallest possible first step ("Pick up your old bat and feel its weight. Sunday evening.") and you seal the pledge on-chain , where you can't quietly delete it. 🕯️ Lay it to rest. It says goodbye properly: a personal eulogy, spoken aloud, and a permanent on-chain stone. Closure is a feature, not a failure state. Every anonymized session joins the Atlas of Abandoned Passions , a live map of what humanity gives up, at what age, and what killed it. When I ran my own confession through it, the app decided my passion should speak as " Your old cricket kit bag ." Its first words: "It's been a while since you hoisted me up here, hasn't it? I still remember the thrill of a good cover drive, too." I built a thing and it emotionally wrecked me on the first test run. Working as intended. Demo 🔗 Live app: https://ember-himanshus-projects-acd54afd.vercel.app Try it in two clicks: tap an example confession (cricket at 17, the closet guitar, the novel at chapter three), headphones on.

This is a follow-up to my earlier post, " Automating a config migration with a one-shot launchd job ." Some breaking changes come with a known expiration date, and you can prepare for them long before they land. This time the external event was the end-of-life of Fable 5 (2026-07-07), and I'll walk through how I designed a launchd job you set up today, that fires only on the target day, and that removes itself once it's done. The whole thing started with the thought, "manually fixing this on the shutdown day is going to be annoying." But I also didn't want to run a script every morning that needlessly rewrites JSON. What I landed on was a three-part set: a date gate, a jq rewrite with a backup, and self-unload. The problem: on the day I learn about a deprecation, I want to plant a job that "only runs on the target day" Right now, ~/.claude/settings.json looks like this: { "model" : "claude-fable-5[1m]" , ... } The moment I learned Fable 5 would end on 2026-07-07, creating a calendar reminder to manually rewrite this "model" felt too flimsy — I'll forget. On the other hand, making "a daemon that checks the date every time it boots" is overkill. What I wanted was a job I could set once and leave alone, that runs when the day arrives, and then disappears. launchd can fire at a specified time via StartCalendarInterval . But you can't express "just once at 9:00 on 7/7"; you need a combination of recurring and date-fixed slots. Specifying multiple slots and absorbing the redundancy with idempotency is the standard trick on macOS launchd. The implementation: the three-part set Here's the full ~/.claude/scripts/model-transition-0707.sh (comments omitted). #!/bin/bash set -uo pipefail SETTINGS = " $HOME /.claude/settings.json" LOG = " $HOME /.claude/logs/model-transition.log" PLIST = " $HOME /Library/LaunchAgents/com.shun.model-transition-0707.plist" log () { echo "[ $( date '+%F %T' ) ] $* " >> " $LOG " ; } # ① 日付ゲート if [ " $( date +%Y%m%d ) " -lt 20260707 ] ; then log "ski

Meta has deactivated the Muse Image capability to create AI deepfakes of any public Instagram account you @-mention.

Johannes Heidecke’s departure comes as OpenAI tries to further integrate its research and safety teams.

CISA said it "missed" an opportunity to get ahead of the security incident by not creating a response plan ahead of time.

I game in a room that warms up fast. I could see CPU usage in Task Manager and watts in HWiNFO if I went looking. What I actually wanted was simpler: How much heat is this machine putting into the air right now? Not in a spreadsheet. In plain language I could glance at while the PC was running. The gap Lots of tools show watts and temperatures . Almost none answer room heat : BTU per hour Heat accumulated over a session Plain context like "about a quarter of a space heater" With ambient temp: still-air rise or rough exhaust CFM The conversion is straightforward ( BTU/hr ≈ watts × 3.412 ), but I didn't want to do it in my head every time. So I built HeatLens — a small desktop widget built around room heat, not raw sensor dumps. What HeatLens shows Total wattage — what the PC is drawing now Heat dissipation — BTU/hr or kW Session heat — BTU or kWh since launch Max temperature — hottest live sensor Trend graphs — watts, heat, and temp over time CFM estimate — with ambient temp: rough exhaust airflow for a +10 °F rise Still-air rise — how fast a reference room would warm with no ventilation Estimated power is labeled separately from measured sensors. Where the data comes from LibreHardwareMonitor / Open Hardware Monitor (HTTP + WMI on Windows) nvidia-smi for NVIDIA GPUs Linux RAPL / hwmon when exposed by the kernel Labeled fallbacks when direct power sensors aren't available On Windows, best results: LibreHardwareMonitor with Remote Web Server on port 8085 . What it is not HeatLens is not a replacement for a Kill-A-Watt at the wall. Software usually can't see monitor power, full PSU loss, or every platform rail. A plug-in meter is still the most accurate whole-system reading. HeatLens is for context : "~400 W gaming → ~1,400 BTU/hr into the room" Session heat over an hour or two Rough CFM / still-air numbers as sanity checks — not duct design Things I learned building it Sensor coverage is messy. Different backends, missing rails, and estimates that need clear labeling.

This is a submission for Weekend Challenge: Passion Edition What I Built I built a personal tribute website for my cat Juma. The goal of this project was to create a simple webpage to bring back the feeling of the old internet. I have always loved the creativity of old-school websites and things like Neocities pages, Tumblr blogs, pixel art, animated backgrounds... Websites made with personality instead of just functionality. So, I wanted to recreate that feeling by making a small corner of the internet dedicated to someone very special to me: my cat Juma Maruá Ganache. Demo Code You can check out my GitHub repository: thaisavieira / juma How I Built It I built this project using simple and classic web technologies: HTML for the structure of the page; CSS for animations, gradients, responsive design, and the retro visual style; JavaScript for interactive elements such as falling stars and dynamic effects.

Offloading fan-out work to Render Workflows (docs linked above). Retries and parallel tasks live there. My problem is the web layer. First version: return 202, tasks POST back to /internal/events with a bearer token, UI subscribes over SSE. Added a reconciler that polls the Render API every 2s anyway because I didn't trust callbacks alone. Second version: skip callbacks entirely. One POST stays open, poll getTaskRun every 1.5s in an async generator, stream SSE until the digest finishes. Postgres at the end. Less wiring, but the HTTP request lives for the whole run. Both work on small traffic. I'm not sure which one I'd keep if this wasn't a demo. Restarting the API wipes in-memory viewer state in the callback version. Workflow keeps going, which is fine, but the UI looks stuck unless you reconcile. Polling version doesn't have that split because the request IS the session. Has anyone shipped callbacks + poll backup long term? Or do you pick one and accept the downsides?

I built LiveShop , a mini live-shopping stream UI, to answer a question I kept running into as a frontend-curious grad: tutorials teach you how to render a list, but they never teach you what happens when that list gets hit with the kind of traffic a real live stream produces. So I built something that would force the problem to show up, then fixed it, then measured whether the fix actually worked. The setup LiveShop simulates a live-shopping broadcast - the kind of interface a small merchant might use to sell products while streaming. A mock event engine fires chat messages, reactions, and purchase notifications on an interval, standing in for what a real WebSocket connection to a streaming backend would deliver. On top of that sits a chat feed, a scrollable product carousel, and a floating reaction animation layer. None of that is unusual. The interesting part started once I asked: what happens when message volume spikes? Where it breaks A naive chat feed is just messages.map(m => <ChatRow key={m.id} {...m} />) . It's the first thing anyone reaches for, and it's fine — right up until it isn't. At 50 messages, nothing looks wrong. At a few hundred, every new message triggers a full re-render pass across every row in the DOM, including the hundreds that have already scrolled out of view and that nobody can see. The browser is doing layout and paint work for pixels that aren't on screen. In a real live stream, this is exactly the wrong failure mode, because message volume doesn't arrive evenly. It spikes — right after a product drop, right when something funny happens on stream, right when a popular creator says something quotable. That's precisely the moment a chat feed can't afford to stutter, and precisely the moment a naive implementation is most likely to. What I measured Rather than guess whether this mattered, I built a way to test it directly. LiveShop has a "Simulate spike" button that fires 500 messages instantly, plus a live FPS readout using requestAnimat

The status of the controller As of March 2026, the Kubernetes SIG Network stopped maintaining ingress-nginx. That is the controller a lot of clusters have been running for years. A CNCF blog post published July 9 walks operators through the state of play. The headline for anyone still on it is short: unpatched CVEs, and no more feature work. The post names two operational risks explicitly. New security issues will not receive upstream fixes. Feature updates and community support have stopped. If your ingress plane is a piece of infrastructure you have not touched in a while, this is the reason to pull it up in this quarter's planning doc. What it means at 3am An ingress controller sits between the internet and your services. When it drops a request, you find out from your users. When it takes a CVE and no one is patching, you find out from a scanner or from a report. Neither is a good discovery path. The controller also carries the exact set of annotations, TLS defaults and rewrite rules your workloads rely on. Nothing about a retirement changes the version you have in production today, so the immediate blast radius is zero. The risk is on the calendar, not on the pager. That is the kind of risk teams reliably defer until a scanner flags an unpatched CVE. The two paths CNCF lays out The post frames the choice as a fork. Path A is a lateral swap to another Ingress controller. The example named is Contour, described in the post as Envoy-based. This keeps you on the Ingress API and mostly moves the problem of who is patching. Path B is modernization to the Gateway API, described in the post as the upstream-backed successor to Ingress. The CNCF post points at ingress2gateway to automate the translation, and recommends an incremental rollout: run the new plane in parallel and move non-critical workloads first. The stopgap version is a mix. Adopt Contour to buy time on maintained code, then schedule the Gateway API move on your own calendar rather than under duress. What

Let's be real: our personal medical history is a mess. It’s a chaotic mix of PDF lab results, grainy scans of prescriptions, and cryptic Electronic Medical Records (EMR) scattered across different hospital portals. If you’ve ever tried to remember exactly when a specific symptom started or how your cholesterol has trended over the last decade, you know the "search" struggle is real. In this guide, we are moving beyond simple folders. We are architecting a Personal Health Knowledge Base using a modern Vector Database and RAG (Retrieval-Augmented Generation) pipeline. We’ll leverage Qdrant for high-performance similarity search, Unstructured.io for complex document parsing, and Sentence-Transformers to turn 10 years of medical jargon into searchable embeddings. By the end of this post, you'll have a system capable of cross-year symptom correlation and instant medical history retrieval. The Architecture: From Pixels to Insights 🏗️ The biggest challenge with medical records isn't storage; it's ingestion . Medical PDFs are notoriously difficult to parse because they often contain nested tables and checkboxes. Our pipeline handles this by isolating the layout before embedding. graph TD A[Raw Medical Data: PDFs, Scans, EMRs] --> B[Unstructured.io: Partitioning & OCR] B --> C[Text Chunking & Cleaning] C --> D[Sentence-Transformers: Vector Embedding] D --> E[(Qdrant Vector DB)] F[User Query: 'Show me my blood sugar trends since 2015'] --> G[FastAPI Interface] G --> H[Query Embedding] H --> I[Vector Search in Qdrant] I --> J[Contextual Results + LLM Synthesis] J --> K[Actionable Health Insight] Prerequisites 🛠️ To follow along, you'll need: Python 3.9+ Unstructured.io : For the heavy lifting of PDF/Image parsing.

My GPT got dumber after the update" gets blamed on the model regressing, or on you prompting worse. Both are unfalsifiable, and both send you to fix the wrong layer. The layer that actually moved is the one you can pin. "The model" is two layers. The weights — the trained network, slow to change, and when they do change it's announced under a new name. And the wrapper — the router that picks which model answers, the system prompt, the default reasoning effort, verbosity caps. The wrapper changes silently, on its own schedule, per product. It's almost always what moved under you. So stop re-tuning prompts to chase it. Pin the wrapper: Force the route. Don't leave it on Auto — set Thinking (or say "think hard") so the router can't quietly demote your prompt to a faster, weaker model. OpenAI's own GPT-5 launch post describes exactly this router (it scores prompts "simple" vs hard); after the backlash they put the picker back (Auto/Fast/Thinking — TechCrunch, Aug 2025). Pin the version. If you build on a model, call its exact versioned ID via the API. A model ID's weights don't change — new versions ship under new IDs — so router and system-prompt churn can't reach you. Own the harness. Running agents? Set the system prompt, reasoning effort, and verbosity yourself instead of inheriting a default. Anthropic's own April 23 post-mortem is the proof: six weeks of "Claude Code got worse" traced to three wrapper changes (a reasoning-effort downgrade, a reasoning-history bug, a verbosity cap their ablations put at ~3% quality) — API weights never touched. A real weights change — a new model — will still move behavior. But that's announced, and you choose when to adopt it. The silent stuff is all wrapper, and the wrapper is the part you can pin.
