We are exploring an experimental blockchain mechanism called "Proof of Weather" In the world of blockchain, various methods are used to achieve network consensus. The most well-known is Bitcoin’s Proof of Work (PoW). While PoW is an excellent mechanism, it has one major drawback. It consumes an enormous amount of electricity. At one point, I found myself wondering: Does blockchain really require such vast computational resources? Isn’t there something else that’s needed? This led to the creation of Dawn, the experimental cryptocurrency project I am developing, and an experimental blockchain mechanism called Proof of Weather. In this article, I will discuss: Why I decided to use weather How Proof of Weather works Security considerations Implementation in Rust How Does Proof of Work Work? Proof of Work is often explained as a mechanism where computers compete against each other in computational tasks. However, one important property of PoW is that it produces outcomes that are difficult to predict in advance. Miners repeatedly perform massive amounts of hash calculations, and only those who happen to meet the conditions can generate a block. This unpredictability plays a role in determining who can produce the next block. However, this process consumes enormous amounts of electricity worldwide. So I wondered: Aren’t there already phenomena in nature that are difficult to predict? Why Weather? Proof of Weather utilizes weather data as that unpredictable element. Of course, weather forecasts exist. However, Temperatures several days in the future Atmospheric pressure at specific locations Precipitation Wind speed and other factors cannot be predicted with absolute certainty. In particular, when combining observations from multiple locations, it becomes even more difficult to accurately calculate future values in advance. In other words, meteorological observations have the potential to be used as A real-world information source where future values cannot be fully predic

This is a submission for the GitHub Finish-Up-A-Thon Challenge Note: AI is currently a Hot Topic in...

Just wanted to share my journey after 3.5 years of building a live web analytics tool from scratch, and without AI: WireBoard.io As a web publisher for the last 15 years, I used UA (before GA4) and then Chartbeat. I always loved real-time. At the beginning of the internet I spent my time on IRC, which was great and a huge change from newsgroups and forums. A few years later, Chartbeat was changing its customer base and focusing on big news publishers, and my workflow was about to change with it. I loved being able to watch my traffic live and spot anything unusual, day by day, compared to the same day the previous week. So I decided to replace it with my own product, but with the things their tool was missing. I spent about 8 months thinking it through and sketching different architectures to handle the load and the logic of the data processing pipeline. Then I learned to code in Go (which was surprisingly easy) and built an MVP. After some iterations, I worked on the frontend (Laravel + React) and kept improving the product based on user feedback. The features I couldn't find anywhere else: Truly real-time data via streaming instead of polling. Merging data from different websites into one chart, so I can see at a glance whether traffic is unusual "today" compared to last week. A flexible dashboard, arranged like widgets on a phone. I mostly worked on this quietly and didn't talk about it much on social media or anywhere else, since I'm a dev and not a marketer. This is my biggest project, and I've enjoyed the long journey. All of this happened before the AI era, which turned out to be good timing: I can work on the codebase knowing exactly what does what and where. Over the last 6 months I've experimented with using Claude on some parts of the project (only the frontend), but in limited areas: Performance improvements (useMemo, etc.) Security reviews (not strictly needed, but reassuring when it confirms what I expected) CMS (blog section) The tech stack: Data proc

TL;DR I built AutoMaintainer , a multi-agent AI system that transforms GitHub issues into production-ready pull requests during the Qwen Cloud AI Hackathon. It coordinates specialized agents (Issue Analyst, Developer, QA, Security, Documentation, Reviewer) to solve problems like a real engineering team—all while keeping humans in control. Here's what I learned. The Problem Open-source maintainers face a brutal reality: 📚 Overwhelming issue backlogs 🔄 Repetitive bug fixes and documentation gaps ⏱️ Code review bottlenecks 😴 Burnout from handling everything solo Existing AI tools help write code, but they don't orchestrate the entire workflow: planning, development, testing, security review, documentation, and human approval. What if we could build an AI engineering team that collaborates like real developers? The Solution: AutoMaintainer AutoMaintainer is a multi-agent orchestration system that mirrors a real software company: Issue Analyst – Reads GitHub issues, extracts requirements, assesses severity Architect – Analyzes repo structure, designs the implementation approach Developer – Writes code, updates files, creates new modules QA Tester – Generates tests, validates fixes, checks edge cases Security Agent – Scans for vulnerabilities, prevents dangerous patterns Documentation – Updates changelogs, PR summaries, release notes Reviewer – Scores code quality, recommends improvements Human Approval Gateway – Final human review before merge The result? A pull request that's analyzed, built, tested, secured, documented, and reviewed—all before a human ever sees it. Tech Stack Frontend Next.js – React framework for the dashboard UI Tailwind CSS – Rapid, utility-first styling TypeScript – Type safety for the frontend layer Backend FastAPI (Python) – Lightweight, async-first API Qwen-compatible LLM API – AI model integration for all agents SQLite + Async (aiosqlite) – Persistent pipeline and memory storage Redis-ready architecture – Prepared for distributed queuing Integr

It is time to put my proposition made in my previous blog post to the test. Is it possible to spec an application for execution by an agent without encoding it in source? Let's find out. One type of application every knowledge worker is familiar with is task management. Every task has a lifecycle status, dependencies on other tasks, and a history of progress. Let's give agents their own. TaskTrack is a simple but non-trivial task management system variant implemented as a Specify spec. It goes beyond checkbox-based to-do lists that agents sometimes use internally and mimics the key system features listed above. TaskTrack defines two procedures: a "Plan Authoring Run" to create an interconnected set of tasks from requirements and a "Plan Execution Run" to advance a previously authored plan toward completion. One execution run might not always be enough to achieve completion, because TaskTrack allows requesting human feedback and incorporating it during the next execution run. Furthermore, every execution run is divided into "Task Processing Run" sub-procedures to allow for advanced agent context management. TaskTrack implements all of this in less than 300 lines of text. If the implementation used source code, then, depending on the programming language, this would be enough space to implement only the required file I/O operations (TaskTrack uses files for simplicity, not a database). Natural language can easily become quite bloated, but a stringent, scientific writing style and extensive use of what the Specify standard offers can effectively counter that. The official test is, how could it be any other way, the implementation of yet another uninspired Breakout clone. The requirements, the completed TaskTrack plan, and the deliverable are contained in the repository. If you want to run the test yourself, the included README file contains the necessary information, including the launch prompts for both the authoring agent and the execution agent. Please note how both

For months I had the same annoying problem: folders full of screenshots I couldn't actually use. Lecture slides, PDFs I own, scanned pages — all just images . I couldn't Ctrl-F them, couldn't copy a line out, couldn't get my OS to index them. A picture of text is useless the moment you need to find something in it. So I built CapDrop to automate the whole chain on Windows. This is a write-up of how it works under the hood and the bugs that nearly broke me. The core idea You draw a capture box over a page, pick a page key (Page Down, arrow keys), set an interval, and walk away. CapDrop then: Captures each page on the interval Presses the page key for you to advance Auto-crops margins and toolbars out of every shot Runs OCR locally Binds everything into a single PDF with a real text layer The result is one document you can search, not a pile of images. The stack Electron for the app shell and capture/UI (I already had window management, hotkeys, and floating-bubble export working — no reason to rewrite). A Python OCR sidecar (RapidOCR) spawned as a child process. OCR runs 100% locally; nothing is ever uploaded. jimp for auto-crop, with a 12px safety pad so edge text never gets clipped. pdf-lib to bind the pages and inject the OCR text layer. The Electron + Python-sidecar split was a deliberate choice. People kept telling me to rewrite the whole thing in Python "for the OCR," but the Electron app already had everything except OCR. Adding a sidecar was a few hundred lines; a rewrite would've been months. The bug that cost me two days After adding the OCR pipeline, my global capture hotkey developed a 4-second delay on the first press. Cold, every time. I guessed wrong twice — thumbnail size, then a race condition. Both were dead ends. The only thing that actually found it was instrumenting the hot path with timing logs. The culprit: a fs.readFile of a tiny 749-byte settings.json on every hotkey press. On a cold start that read was taking 2–4 seconds — Windows Defender's

NewsScope is a real-time news search engine: search a topic, filter by language, category and country, get live results from the NewsData.io API. No React, no bundler, no npm dependencies — just HTML, CSS and vanilla ES2020+. This post is about a few specific decisions in the architecture that I think are worth sharing. The module structure The JS is 9 files, each with a single responsibility, loaded in dependency order directly in index.html : config.js → i18n.js → data.js ↓ ↓ ↓ helpers.js → geo.js → ui.js ↓ ↓ ↓ render.js → api.js → main.js Every module only uses things defined in modules loaded before it. main.js registers all event listeners and calls init() — it's the only file that touches everything. config.js is the smallest file in the project, since it only defines the state object and two constants. All app state lives in a single flat object in config.js , accessed as a global: const S = { apiKey : '' , query : '' , activeQuery : '' , language : ' es ' , category : '' , country : '' , results : [], nextPage : null , loading : false , hasSearched : false , error : null , }; No state management library. When something changes, the relevant render function gets called explicitly. Simple, and easy to trace. Translating search intent, not just the UI Most i18n stops at labels and button text. NewsScope has 10 predefined topic shortcuts (AI, Climate, Economy, Cybersecurity…) that trigger a search. If a user picks "Cybersecurity" while the app is set to Japanese, the keyword sent to the API should be in Japanese — not a transliteration of the English word. The solution is a TOPIC_KEYWORDS map in data.js : const TOPIC_KEYWORDS = { ai : { es : ' inteligencia artificial ' , en : ' artificial intelligence ' , ja : ' 人工知能 ' , ar : ' الذكاء الاصطناعي ' , /* 7 more */ }, cyber : { es : ' ciberseguridad ' , en : ' cybersecurity ' , ja : ' サイバーセキュリティ ' , /* 8 more */ }, // 8 more topics }; One string per language, per topic. Switching the UI language and then selecting a

I’m building Obex, a faith-rooted self-control app for men who want to quit porn and stay consistent with daily discipline. The stack is Expo / React Native, with a web landing page and a desktop blocker companion. Core features: Streak tracking and rank progression Panic Mode for urgent moments Accountability partners Blocker support on desktop Christian-focused language and reminders The goal is to make the product feel practical rather than preachy. People usually respond better to clear feedback loops, a visible streak, and a calm recovery path after setbacks. If you want to see it or give feedback, the site is here: https://obex.so

Stop shipping a 1990s C library to compute planets. Xalen is the pure-Rust, Apache-2.0 replacement for Swiss Ephemeris. If your app does astrology, you already know the dependency. Swiss Ephemeris: a C library from the 1990s, a folder of binary .se1 data files you have to ship and locate at runtime, and a license that is either AGPL or you pay for a commercial seat. For 30 years it was the only serious option, so everyone just swallowed the cost. That era is over. Xalen Ephemeris is a full planetary engine written in pure Rust, with no unsafe in the core engine (the only unsafe lives in the optional FFI, Node and WASM binding crates), released under Apache-2.0. No C toolchain. No data files to ship. No copyleft clause waiting for the day you try to make money. It is built to replace Swiss Ephemeris in production, not to admire it from a distance. Python is live on PyPI and the Rust crates are live on crates.io: # Python pip install xalen # Rust cargo add xalen-ephem xalen-time xalen-ayanamsa xalen-vedic Node and WASM build straight from the repo. Repo: https://github.com/vedika-io/xalen-ephemeris Switching takes one line Xalen ships a pyswisseph-shaped API on purpose. Migrating an existing codebase is a find-and-replace: # before import swisseph as swe # after import xalen.swe as swe jd = swe . julday ( 1990 , 6 , 15 , 10.5 ) xx , ok = swe . calc_ut ( jd , swe . SUN , swe . FLG_SWIEPH | swe . FLG_SPEED ) # same argument order, same SE_/SEFLG_/SIDM_ constants, same tuple layout Your function calls do not change. Your data-file directory disappears. Your license problem disappears. Xalen vs Swiss Ephemeris Line them up and the gap is hard to miss. Swiss Ephemeris is C from the 1990s, shipped as a native library you compile and link, fed by .se1 data files you have to bundle and locate at runtime, under AGPL or a paid commercial license. Xalen is pure Rust with no unsafe in the core engine, thread-safe, with no native dependency and no data files for the analytical eng

StudyQuiz has moved forward since the first frontend MVP release. This update focuses less on adding major new features and more on making the app smoother to use, safer to change, and more reliable in production. What’s New Logout functionality Call-to-action section on the user dashboard Edit and delete functionality for questions and answers Guest Mode restrictions for editing and deleting questions and answers Integration tests for core backend workflows Improved Enhanced quiz user experience and feedback Improved quiz creation user experience Improved navigation across the application More reliable page reload behavior for protected routes Fixed Fixed 500 errors when reloading protected frontend pages Fixed production database session configuration issues Improved reliability around authentication-protected routes Why This Release Matters This release is mainly about stability and maintainability. I added integration tests and a GitHub Actions workflow so future changes are checked automatically before they silently break existing behaviour. StudyQuiz now feels closer to a maintainable product rather than just a working prototype. Coming Next The next major focus is slide upload and AI-assisted quiz generation, allowing users to generate structured quizzes more directly from their study materials.

Most SaaS founders build the dashboard first. It looks impressive in demos, investors love screenshots, and it feels like real progress. We did the opposite. Here's why. The real reason approvals fail When I started building TeamAutomation, I interviewed a dozen people about their approval process. Every single one said the same thing — approvals don't fail because people reject them. They fail because nobody follows up. The requester sends the request. The approver gets busy. Nobody wants to be the annoying person who keeps pinging. Days pass. Project blocked. A dashboard showing "pending approvals" doesn't fix this. The approver still has to remember to open it. Nudges are the product We ship automatic reminders at 24 hours, 3 days, and 7 days — directly in Slack where the approver already lives. No new app to open. No new habit to build. The accountability shifts from the requester to the system. That's the whole unlock. What we learned Build the thing that changes behavior first. The dashboard is just reporting. Nudges are intervention. If you're building any kind of workflow tool, ask yourself — what happens when nobody does anything? Your answer to that question is your core feature. What's next Still in early beta. Slack Directory approval pending. Zero users, full transparency. If you're dealing with approval chaos in your team, drop a comment — happy to give early access.

Most developer tools in 2026 want your data. They want you to create an account, sync to the cloud, share analytics, and join a team plan. Every new tool is another service that knows what you are working on. I wanted something different. CodeFootprint CodeFootprint is a Mac app that tracks file changes in your project folders. It records every edit with full diff, every deletion with recoverable content, and precise timelines for everything. And it does all of this without ever connecting to the internet. How It Works Select a folder to monitor Code as normal — CodeFootprint records in the background Open it anytime to see what changed, when, and how Export change traces to share with AI tools for debugging The Design Decision I made a deliberate choice: no accounts, no cloud, no telemetry, no data leaving your machine. Not because cloud is bad, but because your project files are some of the most sensitive data you own. Your code, your configs, your unpublished work — a file change tracker sees all of it. A tool that watches everything you change should be trustworthy by design, not by promise. For Developers Who Use AI Tools If you work with multiple AI coding tools, CodeFootprint gives you something valuable: a shared context you can export. Instead of manually explaining to each new AI tool what happened in your project, you hand it a trace file and say "here is the history." Available Now CodeFootprint is on the Mac App Store . No account needed. No internet required. Your files stay on your machine. More convenience. More protection. More peace of mind.

If you've used other browser-based code editors, you've probably noticed that the terminal feels off. You can run a script. You can print to stdout. But the moment you try to install a package and then actually use it in the next command, something breaks. The environment doesn't carry over. It feels like every command starts from scratch in a vacuum. That was the problem I wanted to solve when building the terminal for Cloudpen. Not just a place to run isolated snippets, but a proper environment where you can install dependencies, run build tools, and have everything you did in one command still be there for the next one. What most cloud terminals get wrong The core issue is that running code in the browser is hard to do without cheating somewhere. A lot of tools use sandboxed environments that look like a terminal but don't behave like one. They're good enough for demos. They fall apart in real work. The thing developers actually need is simple: if I install something, it should be there when I run the next command. That's it. That's the whole requirement. Surprisingly few cloud tools actually deliver it. How Cloudpen handles it Without going into the full technical detail, the short version is this: every command runs in a completely isolated environment, but all commands within your session share the same filesystem. So when you run npm install, those files are written somewhere. When you run your next command, that somewhere is exactly where it looks. Package installs work. Build tools work. Multi-step workflows work. And because each command runs in a clean, isolated environment, there's no bleed between users or sessions. The current terminal is optimized for commands that run to completion, while live application previews are handled through Cloudpen's deployment system. On the free plan, you can run any file in your project and see the output directly in the terminal. The live coding environment where you type commands yourself is on the Pro plan. Both use

AirDrop only works between Apple devices. Most alternatives require an app install, a cloud account, or route files through a third-party server. I wanted something simpler: Open a URL → discover nearby devices → send files. So I built LocalDrop — a peer-to-peer file transfer app that works entirely in the browser over local Wi-Fi. GitHub: https://github.com/akshaykdadheech/localdrop Live Demo: https://localdrop-4fddd39fb6ad.herokuapp.com How It Works Devices connected to the same Wi-Fi network automatically discover each other through a lightweight signaling server. Once discovered, WebRTC establishes a direct peer-to-peer connection: Browser A ──► Signaling Server ◄── Browser B └──────── WebRTC P2P ────────┘ The signaling server only helps devices find each other. File transfers happen directly between browsers via WebRTC and are DTLS encrypted, so the server never sees your files. Interesting Challenges Backpressure Handling WebRTC DataChannels on Chromium have a ~16 MB buffer limit. Sending data too aggressively can crash the tab. I solved this using: bufferedAmountLowThreshold Flow control based on drain events Cross-Platform Compatibility Different browsers expose different capabilities. Android Chrome supports the File System Access API iOS Safari does not This required separate file-receiving flows for each platform. Large File Transfers Keeping multi-gigabyte files in memory isn't practical. On Chrome, showSaveFilePicker() is triggered after the transfer completes, allowing transfer progress to remain visible throughout the process without buffering everything in RAM.

I'd love feedback from anyone who's worked with WebRTC DataChannels, especially on mobile browsers. If you find the project useful, a

Last week I had a single tool: a JSON-to-TypeScript converter. Today I have 10. I spent a day building a full suite of developer tools - all free, all client-side (nothing leaves your browser), and all open source on GitHub. The Suite DevForge is a collection of tools I built because I kept opening 15 different tabs every day: 1. JSON ? TypeScript Paste JSON, get TypeScript interfaces or types. Supports nested objects, arrays, custom root names. 2. CSV ? JSON Bidirectional conversion with header detection and delimiter support (comma, semicolon, tab). 3. Regex Tester Live regex testing with flags (g, i, m, s, u, y), match highlighting, and replace functionality. 4. Base64 Encoder/Decoder Encode text to Base64 and decode Base64 back to text. Unicode-safe. 5. JWT Decoder Decode JWT tokens into header, payload, and signature components. Read-only - no verification, no security risk. 6. SQL Formatter Uppercase keywords, indentation control. Handles SELECT, JOIN, INSERT, CREATE - the common stuff. 7. Diff Checker Side-by-side text comparison with LCS-based diff algorithm. Color-coded additions and removals. 8. UUID Generator Generate UUID v4 (or v1) in bulk. Copy individual or all at once. 9. Timestamp Converter Convert Unix timestamps to readable dates and back. Shows seconds, milliseconds, ISO 8601, UTC, and relative time. 10. Color Converter Convert between HEX, RGB, HSL, and CMYK. Color picker, presets, named color support. The Tech Stack Zero frameworks. Zero dependencies. Zero backend. Every tool is a single HTML file with embedded CSS and JavaScript. They all run entirely in the browser - no data is sent to any server. Hosted on GitHub Pages. Free forever. Why I Built This I'm a solo developer based in Nepal. Building things that help other developers is how I learn, grow, and (hopefully) earn. The suite is free, but there's a Pro tier ( one-time) that unlocks: File exports Batch operations Custom naming conventions Priority support I also do freelance development

“Did We Already Watch This?” — Building KindaSeen with FastAPI and Next.js A few months ago, my friends and I kept running into the same question whenever we talked about movies, dramas, anime, or variety shows: “Did we already watch this before?” Sometimes we remembered the title but forgot whether we had finished it. Other times, we completely forgot we had already seen it at all. That simple problem inspired me to build KindaSeen, a full-stack personal media repository designed to help users track and organize the media they’ve consumed in one centralized platform. The goal of the project was not only to create a useful application, but also to gain hands-on experience building a real-world full-stack system with modern web technologies. What KindaSeen Currently Supports User authentication with Supabase CRUD operations for personal media records TMDB-powered search functionality Watchlist system Favorites system Persistent PostgreSQL storage Dockerized backend deployment Separate frontend/backend deployment workflow Tech Stack Frontend Next.js React Tailwind CSS Shadcn/ui Vercel deployment Backend FastAPI PostgreSQL Docker Render deployment External Services Supabase Authentication TMDB API integration One of the main goals of this project was to simulate a more realistic production workflow by using a decoupled frontend/backend architecture instead of building everything inside a single monolithic application. In this article, I’ll share: Why I chose this architecture How I integrated TMDB into the application Challenges I faced during deployment What I Learned From Building KindaSeen Why I Chose This Architecture Instead of building a monolith using Next.js API routes, I decided to decouple the application into a Next.js frontend and a FastAPI backend. This decision was driven by three main factors: AI Compatibility & Future Proofing : While researching the job market, I noticed that most companies building AI products heavily rely on Python. By choosing FastA

Last week I built a little dashboard with Claude. Took maybe ten minutes. Then I spent the next hour trying to get it online. ssh in, install docker, write a Dockerfile, set up nginx, run certbot, certbot fails, read the log, oh the DNS hasn't propagated, wait, run it again, open port 443, realize ufw was blocking it the whole time. By the time it was live I'd forgotten what the app even did. I've done that maybe a few hundred times by now. I'm a backend guy, I'm fast at it. But fast at something boring still means doing the boring thing. So at some point I just thought: the AI already wrote the app. Why does it stop right when the annoying part starts? Why doesn't it just deploy the thing itself? The reason is it has no hands. The model can write you a perfect docker-compose file. It can't ssh into your box and run it. No connection to your server, nowhere to hold your key. So I gave it hands. It's an MCP server, vibe-deploy. You hook it up once to a VPS you own, and then you just say "deploy this to notes.mydomain.com" and the agent containerizes it, ships it over ssh, sets up nginx, gets a real Let's Encrypt cert. Node, Python, Go, plain static. It figures out the stack and writes the Dockerfile. No PaaS, no per-seat pricing, no free tier you'll outgrow. A $5 box runs a dozen of my projects and I own the whole thing. The "you gave an AI root on your server??" reaction is fair, so: it runs locally, your key never leaves your laptop. I used a separate ssh key scoped to deploys, not my real one, and you should too. It checks the server host key before connecting and validates everything you pass it, because a deploy tool that pastes your input straight into a shell is a horror story waiting to happen. I had someone audit the security before I put it out. They found two real bugs. I fixed them. It's free and MIT, on GitHub and npm as @cgnguyen/vibe-deploy . I built it because I wanted it. If you live in the same gap between "it works on localhost" and "it's online",
