Il monolite non è il problema: il problema è come lo costruisci

Quando un progetto inizia a crescere, prima o poi arriva la stessa domanda: “Non sarebbe meglio passare ai microservizi?” Più utenti, più funzionalità, più integrazioni, magari un'app mobile da affiancare alla web application, processi asincroni, notifiche e API esterne. A prima vista la risposta sembra quasi automatica: il progetto sta diventando grande, quindi bisogna dividerlo. Non necessariamente. Un monolite può gestire applicazioni molto complesse. Il problema nasce quando mono...

What Happened When DealMind Could Recall Past Objections

What Happened When DealMind Could Recall Past Objections Building persistent deal memory with Hindsight changed how I thought about context, retrieval, and the boundary between application state and agent memory. The first version of DealMind could answer questions about a deal. The more useful version could remember what had happened in previous meetings and use that history when preparing for the next one. That sounds like a small difference. Architecturally, it is not. I was not trying to...

Deal Mind : AI Sales Assistant

I Built a Sales Assistant That Actually Remembers Customers What if your sales assistant could write the perfect email… …but had no idea who the customer was? That bothered me while building AI sales assistants. Today, an LLM can write a convincing email in seconds. It can summarize a meeting. It can prepare talking points. It can even sound like it understands a customer. But there is a fundamental problem: Most AI assistants don't actually remember the relationship. A c...

Autonomous Agents Explained: Why Spend Limits Need Independent Control

TL;DR: Put each autonomous agent's spend ceiling in a control plane the agent cannot write to, and give each workload its own production credential. During key rotation, accept both old and new credentials briefly, move traffic, then revoke the old one. This keeps a compromised tutoring agent from raising its own allowance or turning one leaked key into an account-wide billing event. The rule is deliberately boring: the process choosing model calls must not also control the maximum cost of th...

Herzog Zwei: The Genesis RTS That Invented a Genre Before the Word Existed

Five years before Warcraft: Orcs & Humans taught a generation what a real-time strategy game was, a little Sega Genesis cartridge was already doing the whole thing — base capture, resource economy, unit production, orders, and a two-player versus mode. It just didn't have a name for any of it yet. Technosoft, 1989. Herzog Zwei for the Sega Genesis/Mega Drive. The pitch nobody could sell in 1989 Herzog Zwei (Technosoft, 1989) is the sequel to Herzog , a little...

Cloud computing concepts: scaling, serverless, HA and VPCs explained

Cloud computing is easier to learn as a handful of architecture ideas than as a catalogue of three hundred product names. Every production backend on AWS, Google Cloud or Azure is built from the same eleven cloud computing concepts: scaling, load balancing, autoscaling, serverless, event-driven design, container orchestration, the storage hierarchy, high availability, durability, infrastructure as code and private networking. This article walks through all eleven with the numbers that matter and...

OpenAI DevDay Signals Point to an Always-On Agent, but 'dot' Remains Unconfirmed

OpenAI appears to be building toward a persistent, always-on AI agent , with credible signals pointing to a possible reveal at DevDay 2026 on September 29. What remains unclear is the product's final name, feature set, availability, and price. While some discussion has used the name "dot," the stronger reporting points to a concept that may be branded O or "o," rather than a confirmed product called dot. The distinction matters. An always-on agent would represent a different category of ...

Bringing Caelestia Shell to Ubuntu-Based Distros Like Zorin OS

I really like the Caelestia Shell , and I wanted to use it on my system. However, it doesn't officially support Ubuntu-based distributions, and in my case, I'm using Zorin OS . Still, I wanted to make it work. So, with the help of my AI agent, I started experimenting, trying different things, and fixing issues. After a whole day of hard work, I finally managed to get Caelestia Shell running alongside GNOME! Then I thought: There must be other users like me who want to use Caelestia Shel...

Python Basics in the Matatu Context

Watch a matatu conductor work for one trip and you will see a programmer at full speed. He counts heads. He knows the fare. He takes a KSh 500 note from someone who owes KSh 70 and hands back the exact change without a pause. He also decides, by feel, when the vehicle is full enough to leave. Listen to what he tracks: a number plate, a seat count, a fuel bill and a yes or no on whether the vehicle is full. That is text, a whole number, a decimal number and a true-or-false answer. Python cares...
Local LLM vs Claude Code: 96% of My Requests Failed Locally. Half the Steps Didn't.

Local LLM vs Claude Code: 96% of My Requests Failed Locally. Half the Steps Didn't.

The pitch for running Claude Code on a local model goes like this: point it at Ollama, stop paying per token, keep your code on your machine. I have an RTX 4070 with qwen3.5:4b on it, so I wanted that to be true. Before swapping anything, I counted. I took 100 requests I had actually sent to Claude Code and asked, for each one, whether a local model could have done it end to end. 96 could not. So much for cancelling the subscription. Then I counted a different way, and the answer flip...
