Migrando de Supabase a una arquitectura full Go: La poesía de los binarios estáticos

Cómo el ecosistema Go nos permitió reemplazar un backend hosted por una infraestructura self-hosted elegante, mantenible y completamente gratuita. Hace unos meses tomamos una decisión que parecía arriesgada: migrar una aplicación desde Supabase hosted hacia una arquitectura completamente self-hosted. El resultado fue inesperadamente hermoso. Teníamos una instancia Supabase para autenticación y base de datos. Funcionaba bien, pero dependíamos de sus restricciones y limitaciones para seguir crean

System Design for Beginners: A Practical Practice Path

Originally published on LeetCopilot Blog System design confuses beginners. Follow a repeatable learning path, see a mini-example, and get interview-ready by focusing on trade-offs. Having interviewed junior engineers and new grads, I’ve seen the same pattern: people jump into massive diagrams without a mental model. System design for beginners is less about memorizing buzzwords and more about learning a repeatable way to reason about trade-offs. Once you can tell a story about scale, data flow,

Constela v0.8.0: 5 New Features for AI-Powered UI Development

Introduction Constela is a compiler-first UI language. You write UI in pure JSON — no JavaScript/TypeScript required. The compiler validates and optimizes it, then it runs in the browser. With v0.8.0, we've shipped major updates designed for AI-powered UI development. Here are the 5 new features. When you make a typo, Constela now suggests the correct name: Error [UNDEFINED_STATE] at /view/children/0/value/name Undefined state reference: 'count' Did you mean 'counter'? It uses Levenshte

Batch vs Mini-Batch vs Stochastic Gradient Descent: Three Hikers, Three Strategies, One Mountain

The One-Line Summary: Batch uses all data (slow but accurate). Stochastic uses one sample (fast but noisy). Mini-batch uses a small group (best of both worlds). That's why everyone uses mini-batch. Three friends decide to hike down a foggy mountain. They can't see the valley below. They can only ask other hikers which way seems downhill. But they each have a very different strategy. Before taking a single step, the Perfectionist finds every single hiker on the mountain. All 10,000 of them. She a

AI for Log Anomaly Detection Why It Matters, How It Works, and What Modern Organizations Need to Know

In today’s digital landscape, systems generate massive volumes of logs every second. From web servers and microservices to cloud infrastructure and IoT devices, logs are the lifeblood of system observability, capturing critical information on errors, performance degradations, security events, and user behavior. Yet the very volume that makes logs invaluable also makes them overwhelming: manually scanning millions of log entries per hour is impossible, and traditional threshold-based monitoring q

Error Handling and Console Output in the Hybrid Async-Native Engine for Python

Author: @hejhdiss (Muhammed Shafin P) Original Concept Reference: Hybrid Async-Native Engine for Python – Design Concept In a hybrid Python/C execution model, managing errors and console output consistently is crucial. The engine ensures Python coroutines propagate exceptions naturally, while C threads execute safely in parallel. Additionally, any output from C threads is sent directly to the console as intended. Errors raised inside Python coroutines behave exactly like standard Python ex

Workshop: The AI Tool That Refuses to Forget

While the industry predicts self-improving AI for 2026, we've been using it to ship code. Every AI coding assistant you've used has the same fundamental flaw: amnesia. Ask Claude to refactor a module today, and it will do an excellent job. Ask it to refactor another module tomorrow, and it starts from zero. The patterns it discovered, the edge cases it learned to avoid, the architectural decisions that worked—all gone. You're paying for the same lessons over and over. Workshop exists because we

Weekly #02-2026: New Emails, Angry Coders, and the Editor-Engineer Era

🎙️ Click here to listen on Madhu Sudhan Subedi Tech Weekly → Google is rolling out a feature that allow users to change their Gmail address Big news for Gmail users! Google is finally rolling out a highly requested feature that lets you change your existing email address without creating a brand-new account. Yes, you can finally ditch that embarrassing username from high school! Here’s how it works: You switch to a new address, but your old one automatically becomes an 'alias.' This means y

Under-60ms End-to-End RealTime Remote Desktop on Windows — NVENC/CUDA/FEC

TL:DR Clam: On a wired LAN with server and client on separate PCs, disabling all-intra (IDR every frame) and using low-latency IP (B=0) delivers p50 53 ms, p95 71 ms, p99 93 ms end-to-end. D3D11 Capture → CUDA Resize → NVENC → UDP/FEC → NVDEC → D3D12 Render Clock-aligned frame-level CSV with percentiles/exceedance/1-s worst It feels in control. With p50 53 ms / p95 71 ms / p99 93 ms and most frames in 50–80 ms, common desktop actions (typing, cursor, window drags) stay within a sub

Backing Up GitHub Repositories to Amazon S3 (What Nobody Warns You About)

I didn’t start backing up my GitHub repositories because I distrusted GitHub. I started because I realized something uncomfortable: GitHub had become a single point of failure for work I actually cared about. Between long-lived projects, experiments I might want years later, and repositories that quietly became important, I didn’t like the idea that a deleted repo, a locked account, or a bad force-push could wipe everything out. I wanted an off-platform, boring, automated backup. Amazon S3 fit t
