Gemma , a family of open models, are lightweight, remarkably capable, and have a wonderful "tunability" that makes them perfect for personal projects and enterprise-grade applications alike. But as the ecosystem grew, I found myself asking the same questions over and over: Which exact model size fits my constraint? How do I build an application powered by Gemma that does XYZ? How to deploy a Gemma model to production on Google Cloud for my team to use? To solve this, we put together a living repository called gemma-skills (which we're releasing!). It's a curated, structured collection of developer skills designed to help both humans and agentic AI assistants build beautiful applications with Gemma models without the friction. Let's take a walk through what's inside! The Heart of the Repo: gemma-dev At the center of the repository is our first major skill: gemma-dev . It's a skill file ( SKILL.md ) that serves as a blueprint. It's designed for agents to find what are the latest capabilities, model sizes, good practices, and resources to build with Gemma. Keeping Pace with Rapid Ecosystem Evolution The Gemma ecosystem moves fast, with new models, libraries, and best practices emerging constantly. For developers using foundational LLMs like Gemini, keeping assistant workflows perfectly synced with these rapid releases is a common challenge. Because foundational models are trained on vast, fixed datasets, they don't automatically inherit the day-one nuances of a rapidly evolving framework. This can manifest in a few typical development scenarios: Navigating Version Transitions: General-purpose assistants may default to established standards (like Gemma 2 or 3) even when your project is ready to leverage the latest capabilities of Gemma 4. Aligning with Modern Libraries : Recommendations might occasionally lean toward older API patterns rather than the latest optimized packages. Integrating Next-Gen Features: Cutting-edge implementation details (e.g. Multi-Token Predicti

This is a submission for the Hermes Agent Challenge What I Built Onyx is an autonomous infrastructure operator running 24/7 on my droplet. He manages my entire stack: 6 Next.js deployments, 5 Docker containers, a Minecraft server, fail2ban, Nginx, and UFW. He also helps me write my undergraduate thesis. The difference from every other "AI agent" project I've seen: Onyx doesn't wait for commands. He surfaces problems, patches vulnerabilities, and pushes work forward on his own. When I wake up, there's a session log waiting for me, not a to-do list. The core idea: graduate an AI agent from assistant to operator . A chatbot with tools bolted on doesn't cut it. I wanted something that runs infrastructure while I'm eating dinner, asleep, or in class. Demo Onyx operates through Discord. A normal week: 🔴 3 AM — gateway process failure, no wake-up required A gateway process had a stale PID. Onyx detected it, diagnosed the root cause, restarted it cleanly, and wrote a session log. I found out in the morning. Zero human intervention, zero downtime. 🟡 Dinner — 9 CVEs found across Docker containers While I was eating, Onyx ran a routine audit, found 9 CVEs, rebuilt 3 container images from fresh base images, patched Python dependencies, hardened fail2ban (ban time: 600s to 24 hours), and verified every container came back healthy. 🟢 "Fix it" — two words, full tunneling deployment My friends in Indonesia couldn't connect to the Minecraft server because their ISPs use carrier-grade NAT. I sent Onyx "fix it." He researched solutions, selected playit.gg, installed the tunneling agent, configured a systemd service, and optimized TCP keepalive parameters. All autonomous. 🧠 Accountability loop Onyx noticed I kept asking for things but not acting on the output. He surfaced it: "You keep opening new loops and not closing them." He was right. Now when I open a loop, Onyx tracks it until it's closed or explicitly shelved. 📚 Thesis research partner I'm finishing my undergraduate thesis on e

If you manage PostgreSQL databases across multiple environments, you've probably done this: SSH to the DB host (or connect via psql ) Run CREATE USER jsmith CONNECTION LIMIT 20 PASSWORD '...' Slack the password to the developer Forget to log it anywhere Repeat for every environment, every onboarding, every access request It's tedious, error-prone, and leaves zero audit trail. Here's a better way. What I Built pg-user-api is a lightweight Flask REST API that wraps PostgreSQL user provisioning in clean HTTP endpoints. You register your databases once in a SQLite inventory, then any tooling — CI pipelines, internal portals, Ansible playbooks, or a plain curl — can create and manage users across environments without ever touching psql . GitHub: pcraavi/PostgreSQL-user-creation-API The Problem It Solves In teams that span dev, QA, UAT, and prod, you end up with different patterns of users: App service accounts — named after the host/port combo ( web01_8080 ) Kubernetes workload accounts — named after env prefix + farm ( dv_gearservice ) Individual dev/QA accounts — low connection limits, scoped to non-prod Read-only analyst accounts — prod only, no DDL DBA accounts — CREATEDB CREATEROLE LOGIN , rarely provisioned Each type has different CONNECTION LIMIT values, privilege levels, and naming conventions. Encoding these patterns in an API means the rules are consistent, repeatable, and auditable. Architecture The project is intentionally small — five Python files and a requirements list: pg_user_api/ ├── app.py # Flask app — all endpoints ├── auth.py # HTTP Basic Auth (constant-time compare) ├── database.py # SQLite registry + audit log ├── notifications.py # Notification stubs (Webex / Slack / Email) ├── seed_db.py # One-time setup: creates DB + sample records └── requirements.txt Two credential pairs, clearly separated: PG_API_USER / PG_API_PASS — who can call this API (your team/tooling) PG_ADMIN_USER / PG_ADMIN_PASS — the PostgreSQL DBA role that executes DDL The DBA cr

Daily Learning part twenty-two. I haven't been active in three days due to Eid Al‑Adha. On Tuesday I went to my family house, where we go once in a while. We call it the family house because that's where my grandmother, uncles, aunts, and cousins live. I didn't bring my laptop with me because I wanted to spend some time with my family, which I haven't done in months. I stayed there for the two days of Eid. Today I came back by bus. I was supposed to arrive at 17:00, but due to traffic I arrived at 18:40. When I arrived I ate a small sandwich and got back to work. I started the session at 19:30. The first thing I did was complete the HTML Tables section. It was difficult to learn (at least for me). It covered HTML Tables, Table Borders, Table Sizes, Table Headers, Padding & Spacing, Colspan & Rowspan, Table Styling, Table Colgroup, Exercises, and finally the Code Challenge. Then I did a quiz and the Unit 2 test in Khan Academy and also completed one lesson in Unit 3. Now I have started a Tic‑Tac‑Toe challenge in Python. I watched a video on the minimax algorithm, which the game uses. I have started coding, but I am far from finishing it. I am ending today's session at 23:40. Eid Al‑Adha Mubarak to all Muslims.

I'm a maxillofacial surgeon in Ouagadougou, Burkina Faso — and a self-taught builder who's been coding since medical school. Over evenings and weekends, I shipped Readium — a production AI reading app that lets you discuss books with Claude while you read them, in any language. Built AI-paired with Claude, reviewed and deployed by me. Most "I shipped an AI app" write-ups cover the happy path: clone a starter, glue an LLM, deploy to Vercel. The walls I hit weren't there. They were in the spaces between the libraries. Here are five of them — and what I'd tell myself a few weeks ago. Wall 1 — SSE streaming broke at the seam between the LLM and the browser I assumed streaming "just worked" once OpenRouter returned a stream. It does — until your server-side handler, your reverse proxy, or your browser code introduces a buffer somewhere along the path. The chain has at least three places where buffering can silently kill streaming: The LLM API (fine on its own) Your Node server-side handler (fine if you forward chunks instead of accumulating them) The reverse proxy / CDN (often buffers entire responses by default) The failure mode is always the same: the UI looks exactly like the LLM is slow. It isn't — somewhere between OpenRouter and the browser, bytes are being withheld until the connection closes, then dumped in one chunk. What I'd tell past-me: streaming isn't a feature of the LLM, it's a property of your entire request path. If you can't watch tokens land character-by-character in curl -N against your origin, you don't have streaming, you have a slow non-stream pretending. Set Cache-Control: no-transform and X-Accel-Buffering: no headers from your handler, disable response buffering on every layer in front of it, and verify with curl -N before you trust the UI. Wall 2 — fetch hangs forever on certain hosts (and the fix isn't where you think) I had a proxy route that fetched from an external API. Worked locally. Worked in staging. Deployed to production: the route wo

In my previous series of articles, we mainly explored the theory behind various neural network concepts . In this new series, we will focus on putting that knowledge into practice using code . This will be a fun way to turn what we have learned into something more practical. We will start with the basics and build things step by step. For this article, we will be using the following modules. Importing PyTorch import torch torch is used to create tensors , which store all the numerical data in neural networks, such as: raw input data weights biases import torch.nn as nn This module helps us define and build neural network components. It also allows us to make weights and biases part of the neural network. import torch.nn.functional as F This module gives us access to various activation functions and other useful operations. from torch.optim import SGD SGD , which stands for Stochastic Gradient Descent , is an optimization algorithm used to fit the neural network to data. Creating a Neural Network Now let us begin building our neural network. When creating a neural network in PyTorch, we usually start by creating a class. class MyBasicNN ( nn . Module ): Here, we create a class named MyBasicNN . This class inherits from a PyTorch class called nn.Module . By inheriting from nn.Module , our class gains all the functionality needed to behave like a neural network in PyTorch. Initializing the Neural Network Next, we define the initialization method. class MyBasicNN ( nn . Module ): def __init__ ( self ): super (). __init__ () Here, we define the constructor ( __init__ ) for our neural network. The line: super (). __init__ () calls the initialization method of the parent class nn.Module . This ensures that all the necessary PyTorch functionality is properly set up for our neural network. What Comes Next? The next step is to initialize the weights and biases for our neural network. Before doing that, we first need an example problem so we know what kind of neural network we

Hello Dev Community 👋 I recently built my first web project called Namastra — a simple tool to explore the meanings, origins, and insights behind names. 👉 Live Demo: 💡 Why I built this I noticed that many people are curious about: What their name means Where their name comes from What personality or cultural meaning it carries But most websites are: Too slow Full of ads Hard to navigate So I decided to build something simple, fast, and clean. ⚙️ What Namastra does With Namastra, users can: 🔍 Search any name instantly 📖 Get meaning and origin 🌍 Learn cultural background ⚡ Use a clean and fast interface 🛠️ Tech Stack I built this project using: HTML CSS JavaScript GitHub (version control) Netlify (deployment) Hosted here: [Netlify] Code managed via: [GitHub] 🚧 Challenges I faced As a beginner developer, I faced challenges like: Designing a clean UI Making search functionality smooth Deploying with GitHub + Netlify Structuring data properly But I learned a lot through building it step by step. 🎯 What I learned How to build and deploy a full project How important UI simplicity is How real users think differently than developers How deployment pipelines work (GitHub → Netlify) 🚀 Future improvements I plan to add: More name data Better UI design Categories (religion, origin, country) Possibly AI-based name insights 🙌 Feedback welcome This is my first real web project, so I’d really appreciate your feedback and suggestions. Try it here: 👉 Thanks for reading ❤️ Happy coding!

fd vs find vs ripgrep: I Created 10,000 Files to Settle This Debate TL;DR: fd is ~2.5x faster than find for filename searches, rg demolishes grep by ~3x for content searches, and find + grep combined lose on every single benchmark I ran. But there's a catch: both fd and rg skip hidden files by default, which can bite you if you're not paying attention. Here are the receipts. Why I Did This Every time someone posts a shell one-liner using find on Reddit, there's always that guy in the comments: "jUsT uSe fD, iT's fAsTeR." Then someone else chimes in with "actually ripgrep can do that too." I got tired of the anecdotes. I wanted numbers. Real ones. On real files. So I fired up WSL, generated 10,900 files across 1,506 directories (~143 MB of mixed content), and ran actual benchmarks with hyperfine . No synthetic microbenchmarks, no "I feel like X is faster" — just cold, hard terminal output. Methodology The Test Bed I created a directory at /tmp/fd-benchmark containing: Category Count Details Plain text files 2,000 file_*.txt — 20 bytes each, contains "test content line N" Binary files 2,000 data_*.bin — 15 bytes each Log files 1,500 match_*.log — contains unique "match_this_test_N" strings Config files 1,000 nested_file_*.cfg Nested dir files 1,000 level1_*/level2/level3/deep_*.txt + level1_*/shallow_*.txt Hidden root files 1,500 .hidden_* + .config_*.yml Hidden dir files 500 .hidden_dir/subdir/deep_hidden_*.txt Git objects 500 .git/objects/obj_* Multi-ext source files 800 src_*.{py,js,ts,rs,go,java,rb,php,cpp,h,css,html,json,xml,yaml,md} (50 each) Large binary files 100 large_*.dat — 1 MB each (random data) Total 10,900 $ du -sh . 143M . $ find . -type f | wc -l 10900 $ find . -type d | wc -l 1506 Tools Tested Tool Version What It Does find (GNU) 4.9.0 The OG. Ships with every Linux distro. fd 10.2.0 Rust-based find alternative. Smarter defaults, colored output. grep (GNU) 3.11 Content search. Also the OG. rg (ripgrep) 15.1.0 Rust-based grep alternative.
