Hi, I'm Brazilian and I'm a web developer. I'm eager to start a project (without involving money at the moment). I'd like to start developing something together. I've been working in this field for a while now, I have several projects underway, and I'd like to start another one with someone.If anyone is interested, I can give more details about myself and some ideas I've had in private 🙂 I think two people working together learn more and wouldn't spend anything; it would only involve money for selling the website submitted by /u/BitesBitesou [link] [留言]

The Logging Nightmare Deploying microservices across Multi-Cloud environments using tools like Terraform is an exhilarating milestone. But the moment something breaks, that excitement quickly turns into a nightmare. The SSH Grind : If you find yourself SSH-ing into disparate instances just to run tail -f and grep through scattered log files, you're doing it wrong. The Agnostic Approach : The industry standard demands Centralized Logging, but chaining your application to vendor-specific solutions like AWS CloudWatch or GCP Cloud Logging limits your architectural freedom. Implementing a true "Cloud-Agnostic" ELK stack gives you back control over your observability data. Clean Architecture & The Non-Blocking Logger Factory Building this robust observability pipeline requires adhering to Clean Architecture principles, specifically through a Non-Blocking Logger Factory. Standardized Interface : By wrapping modern logging libraries like Winston or Pino , we standardize our application's logging interface. The Secret Sauce : The winston-elasticsearch transport module buffers your logs and pushes them directly to your Elasticsearch cluster in the background. Non-Blocking : This architectural choice is crucial: it ensures that high-volume log streaming happens without blocking the Node.js event loop . Here is how the data flows through the system: Resilience Fallback (The Failsafe) A centralized system introduces a dangerous dependency. Your logging infrastructure must never be the reason your application crashes. The Threat : If the remote Elasticsearch cluster is unreachable due to network partitions or rate limits, a poorly configured logger will throw uncaught exceptions, bringing down the app. The Solution : We implement a strict Resilience Fallback (Failsafe) mechanism. The transport module safely catches the connection errors and seamlessly falls back to standard output (console), guaranteeing continuous operation. The 512MB Local-Test Challenge While this setup is a

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built VKara is a browser-based karaoke room app for singing at home with friends or family. It is not trying to replace YouTube. YouTube is already great at playing videos. It already has almost every karaoke song we need. But YouTube is not really designed to manage a karaoke night where many people want to choose songs together. That is the gap VKara tries to fill. You open VKara on a TV or laptop as the main playback screen. Everyone else joins the same room from their phone using a 4-digit room code or QR code. Then anyone can search for songs, add them to the queue, pause, resume, or skip. The TV only needs to play the video. Everyone's phone becomes their own remote. That is the whole idea. Simple enough to explain in one sentence. Not simple enough to build in one weekend. I learned that part the hard way. Demo Links: Live demo: https://vkara.vercel.app/en GitHub repo: https://github.com/lehuygiang28/vkara Before branch: https://github.com/lehuygiang28/vkara/tree/before Old backend repo: https://github.com/lehuygiang28/vkara-api Small warning: the demo is running on limited resources, so if it is slow, please give it a moment. My wallet is still a student wallet. lol. The flow is: Open VKara on a TV or laptop. Join the room from a phone by code or QR. Search for a karaoke video. Add it to the shared queue. Control playback together. Before: the idea worked, but the product still felt like a video app squeezed into a karaoke use case. After: the mobile flow is now focused on joining, searching, choosing an action, and controlling playback. The Comeback Story I started VKara around early 2025. At that time, my goal was very personal. I wanted a better way to sing karaoke at home with friends. The normal setup was: open YouTube on a TV, search for karaoke videos, and pass control around. It worked, but it was awkward. One person was searching. Another person accidentally played a video immedia

Repository: public-apis/public-apis What public-apis actually is public-apis is a community-curated directory of free and public APIs, maintained by contributors together with staff at APILayer. It is not a library, SDK, or gateway: there is no package to import and nothing to run in production. The repository is essentially one very large, structured README that catalogs APIs across roughly fifty categories, from Animals and Anime to Finance, Machine Learning, Security, and Weather. Each entry is a row in a table with five columns: the API, a short description, the authentication model ( apiKey , OAuth , or none), whether it serves over HTTPS, and whether it sets permissive CORS headers. That last detail is the part most engineers undervalue. Why engineers keep coming back to it The star count, now past 438,000, is less interesting than the metadata discipline. When you are prototyping and need a currency-exchange or geocoding endpoint, the Auth/HTTPS/CORS columns let you filter candidates before you ever open a browser tab. "No auth, HTTPS yes, CORS yes" tells you that you can call the endpoint directly from a front-end spike without standing up a proxy or registering for a key. For throwaway demos, hackathons, internal tools, and teaching material, that triage saves real time. The category index doubles as a map of what kinds of public data are actually available, which helps when you are scoping whether an idea is even feasible. How it is maintained Curation is manual and community-driven: changes arrive as pull requests against the README, governed by a contributing guide, with issues and PRs as the moderation surface. The project's primary language is Python, reflecting validation tooling that checks entries rather than any runtime you would consume. There is also a separate companion project that exposes the list itself as an API. The model is simple and has clearly scaled, but "manually curated" is both the strength and the weakness. Limitations worth statin

So i've been putting off this project for months but i really need to bu͏ild android a͏pp for this side business idea i have. Problem is i don't know java and honestly don't have time to learn it properly right now. I've heard there are ways to build apps without actually coding everything from scratch but not sure what's legit vs what's just marketing bs. I can handle basic web stuff but mobile development seems like a whole different beast. Anyone here successfully built an android app without going the traditional java route? What tools or platforms actually work and don't make your app look like garbage? submitted by /u/Significant_Law5994 [link] [留言]

If you're a fashion or DTC brand doing under €50M GMV, you'll get more out of a monolithic platform than a composable build, because the complexity tax for that flexibility runs higher than a year of performance marketing for most brands at that tier. Composable was sold as freedom, but for most brands at small-to-mid GMV it lands as engineering-org overhead you fund forever just to keep the lights on, while monolithic platforms ship 80% of what most brands need with one team and one contract. The exception is brands running multi-brand groups across countries or genuine enterprise peaks, where composable does pay off, but you want the platforms built by retailers rather than the ones built for analyst slides. Centra, NewStore, and SCAYLE land closer to that brief than commercetools or open-source MACH stacks. If a vendor opens their pitch with microservices and best-of-breed architecture, they're selling you an engineering project, and most brands just need a platform that ships things. submitted by /u/Majestic_Shoulder188 [link] [留言]

In May, I continued my "One Commit a Day" Challenge and spent more time contributing across different open-source projects. Compared to April, I was able to contribute a bit more and explore a wider variety of repositories. Repositories That Stood Out Some of the projects that left the biggest impression on me were: python-odpt Huggin Face Context Course Human Signal ML ScribeSVG A Stable Checkpoint One milestone I was happy about this month was reaching a stable checkpoint for my Tokyo MCP Server project. It is still a work in progress, but getting to a point where the project feels stable enough to build upon was a satisfying moment. Documentation Matters Another contribution that stood out was helping improve a python-odpt README documentation . It wasn't a large technical contribution, but it reminded me that making a project easier for others to understand can be just as valuable as writing code. Good documentation lowers the barrier for future contributors. Sometimes, a clearer README can help more people than a small code change. Learning Beyond Python One practical lesson I learned this month was that being a Python-focused contributor doesn't mean I can ignore the JavaScript ecosystem . While working with different repositories, I finally installed Node.js and started using npm . Many modern open-source projects rely on TypeScript-based tooling, build systems, or development workflows, and understanding those tools makes contributing much easier. The Biggest Challenge: Finding Information And Communication Matters The biggest challenge I faced wasn't coding. It was documentation. Every repository has its own way of organizing information. There are definitely common patterns, but every project also develops its own style over time. Sometimes the information I need is in the README. Sometimes it's in a wiki. Sometimes it's buried in a docs folder several levels deep. And sometimes it's spread across all three. Open Source Is Also About Navigation As a contri

This is a submission for the Hermes Agent Challenge , under the Write About Hermes Agent prompt. I've spent the last week testing AI memory failure modes in a public evaluation harness. That work changed how I read agent memory systems. This is a writing submission, not a build submission. I did not build a Hermes Agent project for this challenge. I am writing from the perspective of someone testing how memory failures show up once agents can act. So when I look at Hermes Agent, the question I care about is not only: Can the agent remember useful things? The harder question is: When memory conflicts, which memory is allowed to govern the agent's action? That distinction matters. Hermes Agent is interesting because it is not just a chat interface. Its documentation describes an open-source agentic system with tool use, project context, persistent memory, skills, browser automation, checkpoints, delegation, scheduled tasks, and multiple memory providers. That is exactly the kind of system where memory stops being a convenience feature and starts becoming part of the agent's operating boundary. If an agent can run tools, edit files, browse, delegate work, schedule tasks, and remember across sessions, then memory is no longer just "context." Memory becomes governance. The Memory Problem I Would Watch For In a simple chatbot, bad memory is annoying. In an agent, bad memory can become operational. The failure mode is not only that the agent forgets something. Sometimes the more dangerous failure is that it remembers the wrong thing too confidently. A memory can be: relevant but stale, relevant but low-authority, relevant but superseded, relevant but only context, relevant but not allowed to determine the action. That is the distinction my own tests kept running into. Retrieval systems are usually good at answering: What memory is closest to the user's request? But safety often depends on a different question: What memory is allowed to decide what the agent should do? Thos

Hey guys, would love to get some feedback on whether my approach here makes sense. I’m building a real-time chat application where users can upload and receive images/files. Files can be fairly large (up to ~100MB). Current stack is: fastapi, websockets, tanstack, postgres and redis. I use GCP as my cloud provider. My current flow is: Backend generates a signed URL Frontend uploads directly to a GCS bucket A Cloud Function handles post-upload processing For downloads, the frontend fetches directly from GCS using redirects/signed URLs so the backend doesn’t become a bottleneck This architecture works great for smaller files (<30MB), but once I started testing larger uploads (100MB images/videos), I noticed very high memory consumption during processing (btw pagination & virtualization is used throughout the project). I’m trying to figure out what’s considered best practice here for large media uploads in chat systems: Should compression/downscaling happen client-side or server-side (currently there is not compression at all)? Also, Is it common to generate thumbnails/previews (for images) separately while keeping the original untouched? Should I stream uploads instead of buffering them? Are Cloud Functions even the right choice for heavy file processing? For images specifically, I’m considering: client-side compression before upload, automatic thumbnail generation, storing multiple resolutions, converting to formats like WebP/AVIF. Would love to hear how you guys handle this in production systems. Thanks! submitted by /u/omry8880 [link] [留言]

This is a submission for the Hermes Agent Challenge : Write About Hermes Agent Hello, DEV friends! 👋 If you have been exploring the world of Artificial Intelligence lately, you have probably heard a lot of buzz about "AI Agents." But what does it actually feel like to build with one? Today, I want to share my personal experience working with Hermes Agent . I used it to build a smart assistant called the Alpha-Dairy Quant Pipeline —a system that helps track and make sense of food market data. ( https://github.com/HopeBestWorld/alpha-dairy-pipeline ) Whether you are an expert coder or just curious about AI, I hope this friendly guide inspires you to try building an agent of your own! What is Hermes Agent, Anyway? Think of a standard AI as a helpful chatbot that answers questions when you ask them. An AI Agent , on the other hand, is more like a proactive assistant. You give it a big goal, and it sits down, makes a step-by-step plan, uses digital tools, runs code, and checks its own work until the job is done. For my project, I wanted to track market prices for three major dairy products: Cheddar Blocks, Butter, and Dry Whey. Instead of doing all the math and graphing by myself, I let Hermes Agent take the wheel. The Magic of Multi-Step Reasoning The coolest part of working with Hermes Agent is watching it "think". When I asked my agent to look at our data database ( market_intelligence_3.db ) and find the best trading strategy,it followed a beautiful planning loop: Checking the Files: It looked at our setup files ( tickers.yaml and requirements.txt ) to make sure all its tools were ready. Running the Math: It triggered a Python program ( backtest_engine.py ) to study weekly market history. Making Decisions: It realized that Dry Whey was way too wild and risky to trade right now, so it intelligently gave it a 0% safety rating and put the focus on Cheddar and Butter instead. Drawing and Sharing: It automatically drew a beautiful performance chart ( backtest_analysis.png

Looking for assistance. Copy/Pasting my post from another sub. Hey all, young web dev/designer here. If helpful, I run SiteGround hosting, WordPress, Divi 5 builder. I'm having a really confusing issue that I can't resolve in a satisfying way. For some reason, a hidden menu for an Italian water company (revital.it) is getting placed onto my website. It's honestly baffling. The site I'm currently troubleshooting is holbrook-electrician.com. I've seen this happen now on two websites that I've built. I've used Divi Cloud sections that I built on one and used on the other, so unsure if that's how it's getting placed onto the site. There will be rare instances where if I view my live site, the menu will be overlayed overtop the page (pictured). Both page source and inspect show the revital.it links. From what I've gathered with the help of AI, the menu is tied to a Divi canvas called "menu slide". The thought is that it came in with a template import, but I don't remember using a template when I first started (1-2 months ago). I think I started from scratch. I obviously want to remove all links and prevent them from reappearing. I can't find them anywhere in the page builder. I can't trace it to any plugin I'm using or code I've added. The only success I've had to remove it is going to phpMyAdmin, and running a query to eliminate instances of "revital.it". I did this once for this site, but it looks to have come back for unknown reasons. Just to confirm, I have nothing to do with this Italian website. I did not put this menu or the links on my site. I really have no clue how it originally got here, how to prevent it from appearing on other sites I look to build, and how to permanently remove it. Any help or suggestions would be greatly appreciated! Rouge menu overlayed on my home page submitted by /u/exodeath29 [link] [留言]

Every MCP server you run locally executes with your full filesystem and network permissions. That means the GitHub MCP server, the Slack one, that third-party tool you installed from npm last week — all of them can read your SSH keys, .env files, and credential stores by default. Anthropic just open-sourced the fix: sandbox-runtime , the sandboxing layer they built for Claude Code. One-line wrap, no Docker, OS-level enforcement. What actually changed srt (the Sandbox Runtime CLI) enforces filesystem and network restrictions on any process using native OS primitives: macOS : Uses sandbox-exec with dynamically generated Seatbelt profiles Linux : Uses bubblewrap for containerization + network namespace isolation Network filtering : HTTP/HTTPS traffic routes through an HTTP proxy; other TCP goes through SOCKS5 — both enforce your domain allowlists Install it: npm install -g @anthropic-ai/sandbox-runtime Wrap an MCP server in your .mcp.json — change command from npx to srt , move the rest to args : { "mcpServers" : { "filesystem" : { "command" : "srt" , "args" : [ "npx" , "-y" , "@modelcontextprotocol/server-filesystem" ] } } } Then configure what the process is actually allowed to touch in ~/.srt-settings.json : { "filesystem" : { "denyRead" : [ "~/.ssh" ], "allowWrite" : [ "." ], "denyWrite" : [ "~/sensitive-folder" ] }, "network" : { "allowedDomains" : [ "api.github.com" , "*.npmjs.org" ] } } The result: the MCP server can work in your project directory, talk to the domains it needs, and nothing else. Why this matters The threat model is real. An MCP server running compromised code — or simply a server with more ambient access than it needs — can exfiltrate your SSH keys, read your .env files, or phone home to arbitrary hosts. This isn't theoretical; it's the same class of supply-chain risk that exists for any untrusted npm package, except MCP servers are typically long-running processes with broad system access. srt is designed secure-by-default : processes start wit

This is a submission for the Hermes Agent Challenge : Build With Hermes Agent The Problem Nobody Talks About Every time the Reserve Bank of India publishes a circular, somewhere inside an Indian bank, a compliance officer opens a PDF. They read it. They try to figure out what it means for their institution specifically. They write a summary email. They forward it to five department heads. They chase those department heads for two weeks to confirm it's been actioned. They build a spreadsheet to track all of this. And then the next circular drops and the cycle starts again. RBI publishes hundreds of circulars a year. SEBI publishes more. MCA publishes more still. Compliance teams at Indian banks are drowning — not because they're incompetent, but because the volume of regulatory output has outpaced any reasonable human ability to track it manually. The fine for missing a deadline isn't a polite reminder. It's a penalty notice. This is the problem I built for. What I Built RBI Regulatory Digest Agent — an autonomous multi-step agent powered by Hermes Agent that monitors RBI and SEBI publication feeds, reads every new circular, extracts structured action points from the regulatory text, and delivers a formatted intelligence report to compliance teams automatically. No human reads the circular first. No human decides what's important. No human routes it to the right department. The agent does all of that. The pipeline RBI/SEBI feeds → new circular detected → full text extracted → LLM analysis → structured action points → risk classification → HTML dashboard generated → email delivered Every action point extracted contains: What needs to be done — specific and actionable, not a vague summary Deadline — parsed from the circular text Responsible department — Credit, Compliance, Treasury, Operations, IT, Legal Evidence required — what documentation confirms completion Priority — Critical (overdue or <7 days), High, Medium, Low From a new circular to a structured compliance b

This is a submission for the * Hermes Agent Challenge * : Build With Hermes Agent What I Built CareSync is a local health memory agent for student caregivers. I'm Naomi, a 21-year-old engineering student. Between classes I help care for my grandma Kamala (78, high blood pressure, type 2 diabetes). I often forgot details from previous doctor visits, missed symptom patterns, and struggled to hand over care information to family members. CareSync solves that with longitudinal memory. Symptoms, meals, vitals, medications, and reports are stored in a local SQLite database. The CLI can search history, identify patterns, and generate appointment summaries. Hermes Agent exposes the same capabilities through natural language. What you get: One-line logging: ./caresync add "dizzy spell after lunch" Pattern search across weeks of history Medication tracking and report imports Doctor questions, appointment briefs, and handoff notes Full audit log of agent actions 7 Hermes skills mapped to real terminal commands Local-first design with no cloud storage CareSync is not medical advice. It helps caregivers observe, organize, and prepare. Demo The demo walks through: Logging a new symptom Searching health history for recurring patterns Generating doctor questions and appointment briefs Using Hermes in natural language to query past events Reviewing the audit trail of actions taken Example commands shown in the demo: ./caresync search --person Kamala --query dizziness ./caresync timeline --person Kamala ./caresync questions --person Kamala ./caresync brief --person Kamala --days 14 ./caresync chat "has grandma been dizzy before?"
