IONA OS is an operating system written from scratch in Rust. It has its own kernel, its own GUI, its own blockchain protocol, its own programming language (Flux), and — since recently — its own kernel-integrated AI. Not a chatbot. Not a cloud API wrapper. An AI that runs in Ring 0, reads CPU temperature directly, kills processes, synthesises drivers, and optimises the system in real time. The hardest part wasn't making it work. The hardest part was making it trustworthy. When an AI runs in...

I deployed my backend on Render and almost immediately hit a wall. The CNJ (Brazil's national justice council) has a public API I was using to pull data for BidTrack, a side project for tracking legal bids and the issue was that Render provisions servers in North America by default. The CNJ API blocks requests from outside Brazil. Every call returned 403. Then I had two options: add a Brazilian proxy (expensive) or host the API myself on AWS in sa-east-1 (São Paulo). I went with AWS, n...

New chapter in Learning data analytics and data science. The focus now is on Pandas as a Python library alongside Matplotlib and Seaborn for data visualization. Am writing this article to guide beginners who are already or beginning the data analytics and data science profession. Introduction to Python Data Analysis In modern world Data has become most valuable asset. Business, healthcare institutions, financial and even social media platforms rely heavily on data to ...

Our gateway handles a few thousand LLM calls per hour. Mostly internal tools, some customer-facing agents. We noticed something in the logs: a lot of prompts were basically the same question worded differently. "Summarize this quarterly report" and "give me a summary of the Q2 report" hitting the same model, getting nearly identical responses, costing us twice. Multiply that across a few hundred users and it adds up fast. The math on duplicate calls Quick back-of-envelope. GPT...

Each vendor promises that AI coding tools will increase your productivity by 40%. But senior engineers kept a time log. It's the difference between those two numbers that makes you blush. A recent discussion among experienced developers revealed something uncomfortable. When they honestly logged where their hours went — including all the cleanup — that 40% boost shrank to single digits. Sometimes it vanished entirely. The Marketing Number vs. the Real Number Let me explain how...

Protegiendo la Navegación: Detección de Manipulaciones de Señales de GPS en Tiempo Real La dependencia de la tecnología de navegación ha llegado a un punto crítico, y la seguridad de las señales de GPS es más crucial que nunca. Un ejemplo reciente de manipulación de señales de GPS en Hacker News ha resaltado la importancia de monitorear y proteger estas señales para prevenir incidentes graves en la aviación, la navegación y otros campos que dependen de la precisión de las señales de GPS. ...

Most modern programming languages rely on massive external toolchains. Many use LLVM for code generation. Others depend on large runtimes, garbage collectors, or extensive third-party infrastructure. Rux takes a different approach. Rux is a statically typed systems programming language focused on performance, control, and simplicity . It compiles directly to native machine code and is built with minimal external dependencies. Lightweight by Design One of Rux's goals i...

Modern backend systems spend enormous effort optimizing databases, tuning queries, and scaling infrastructure. Yet some of the most expensive production incidents begin with a single innocent event: A cache entry expires. Everything looks healthy. CPU is low. Memory is stable. Latency is acceptable. Then suddenly: PostgreSQL reaches 100% CPU Redis traffic spikes Request latency explodes Pods start scaling Error rates climb Nothing is technically "broken...

GitHub Pages is one of the easiest ways to publish a website online for free. It is great for portfolios, landing pages, documentation, small business websites, and simple frontend projects. I use them all the time as all my code is stored on GitHub. In this tutorial, I will show you how to host your website using GitHub Pages step by step. What is GitHub Pages? GitHub Pages is a free hosting service from GitHub that lets you publish static websites directly from a GitHub repo...

El problema: tu adapter PEFT puede estar filtrando datos sin que lo sepas Imagina que participas en un proyecto de Federated Learning. Tu cliente entrena un adapter LoRA localmente con datos sensibles (médicos, financieros, legales) y lo envía al servidor central. El servidor nunca ve tus datos crudos. ¿Verdad? Falso. Un paper reciente de Shi et al. (2026) demuestra que un servidor malicioso puede corromper el adapter para que memorice muestras completas de tus datos de entrenamien...

Anthropic and OpenAI's publicly available models are explicitly guard-railed so that they refuse offensive tasks. And their cyber-focussed models are gated for enterprises. This leaves SMEs and mid market open to major vulnerabilities. AI can be used as both an adversarial and defensive tool in the world of cyber. A worst case outcome is if only the adversaries have access. Meanwhile, most existing AI cyber tools are just wrappers. The problem is that they still have all the guardrails on from t...

I've been building StartupWiki, a free startup database designed to make it easier to discover and research companies. The original motivation was frustration with how difficult it can be to find information on early-stage startups. Most databases need accounts, or subscriptions, ro just feel too cluttered. I wanted a website that felt like Wikipedia, no accounts, no subscriptions, no weird metrics, just go in, the info is on the page. The project is still very early, but currently includes: Sta...

I have a few projects on Github. I am receiving a lot of spam PRs and requests from vibe coders and bots. Most of them to prop up their profiles. The stars are obviously exaggerated too.

I posted my portfolio here about a year ago ( https://news.ycombinator.com/item?id=45154609 ) and while there was a big response, it was very mixed! It'll probably be similar this time, but regardless of your thoughts about the concept, I think I've done a pretty good job creating one of the most nostalgic corners of the internet, especially with the latest additions. It'll always be up for debate whether this is an effective way to get noticed as opposed to a standard, quick and easy portfolio,...
