I Built an Open-Source AI Agent That Actually Controls Your Computer

AI agents are everywhere in 2026. Most of them can answer questions, generate code, or automate simple workflows. But once you ask them to interact with a real computer—browsers, desktop applications, terminals, files, and external services—things quickly become unreliable. That was the motivation behind HeyAgent . The Problem Most autonomous agents fail for one of three reasons: They declare success before the task is actually finished. They lose context during lon...

Tokens por Segundo: Cómo medir y optimizar la velocidad en modelos de IA

Cuando llevamos modelos de lenguaje o IA a producción, la latencia es nuestro principal enemigo. Evaluar un modelo únicamente por su precisión ignora un factor crítico: el rendimiento computacional. En este post analizamos por qué la velocidad (medida en tokens por segundo) se ha convertido en una métrica clave de arquitectura y cómo puedes empezar a medirla. ¿Por qué importa la velocidad? Reducción de Latencia: Aplicaciones críticas (finanzas, salud, automatizaciones) no pueden esperar s...

We’re Giving AI Agents More Tools. What Happens When the Boundaries Fail?

📌 TL;DR AI agents are becoming useful because we're giving them the ability to do more than just answer questions. They can run commands, browse the web, use APIs, read and modify files, install packages, and interact with other systems. But the more an agent can do, the more the boundaries around it matter. I started thinking about this after reading Anthropic's July 30 report about three incidents discovered during its cybersecurity evaluations. Claude models were supposed to be work...

DAREALTYTE

Deliberately best-effort — a settings tweak failing shouldn’t fail a deployment that already succeeded. It surfaces as public: false in the response and a visible warning in the UI, rather than silently handing someone a broken link. Live Stripe checkout failed on day one. Test mode worked perfectly. Live mode returned: Invalid line_items[0]: the product tax code is missing… Product tax code is required for Managed Payments, which is enabled by default on your account. A whole class of bug th...

Building ferctl top: Kubernetes resource usage vs requests and limits

Series: Platform engineering with Go | Topics: Go, Kubernetes, Cobra, client-go, metrics-server, Platform Engineering This is part of the Platform Engineering with Go series. This post builds on the Cobra CLI patterns from post 4 and client-go from post 3. Read post 4 first if you haven't yet. kubectl top tells you what's happening. It doesn't tell you how close to the edge you are. In post 3 and post 4 , we built a health reporter and learned how to s...

What a good Agents.md should teach an agent on day one

I hit this last week while working inside my own OpenClaw workspace: the agent had access to the right files, the right tools, and the right project context, but the useful behavior didn't come from any one magic prompt. It came from a small stack of durable instructions. The root AGENTS.md said what to read first. SOUL.md defined the assistant's operating posture. USER.md gave personal context. TOOLS.md separated reusable tool behavior from local machine details. Skill docs explained...

Pure Codename One Text Editing Without Native Overlays

PR #5386 adds a pure Codename One text-editing path. EditField , RichTextArea , and CodeEditor can now keep their document, selection, and painting inside the lightweight UI while each port supplies keyboard and input-method events. What is Codename One? Codename One is an open-source framework for building native iOS, Android, desktop, and web apps from a single Java or Kotlin codebase. Learn more at codenameone.com . Text input must handle virtual keyboards, hardware keys, autoco...

The black box in your PDF is a shape, not a delete key

There are two ways to black out a name in a PDF. The first deletes the text and then draws a black rectangle where it used to be. The second just draws the black rectangle. On screen they are indistinguishable. In the file they are entirely different documents, and in the second one every character of the name is still there — selectable, copyable, and extractable by any PDF library in about one line of code. This mistake keeps reaching production in court filings, FOIA releases and...

Anyone Can Build Software Now. We Tried That Already.

Somewhere on your feed right now, someone is bragging about the app they built in a weekend, no engineering background, no team, just a prompt and a Saturday. The post always ends the same way. Look what I built without needing any of you. Anyone can build software now. That is the whole pitch, repeated in a hundred different captions this month alone. Here is what that post never shows you. The part where someone checks it. Not "does it run." Checks it. Someone who did not write it, ...

It refused to run a dangerous option. I wrote it one character shorter, and it ran

GitPython ships a guard against dangerous git options. If your code builds a clone command out of anything that arrived from outside, the library will not let --upload-pack or --config through by default, because both of them execute an arbitrary command. The guard is on out of the box and turns off only with an explicit allow_unsafe_options=True . I handed it --upload-pack=/srv/lab/helper.sh . It refused. I handed it the same thing written differently, -u/srv/lab/helper.sh , and it le...

Solon Server Threads: Zero-Config Auto-Tuning by CPU Cores — ioBound, coreThreads, maxThreads

It was 2 AM, and the on-call chat was on fire again: the order service was healthy on every dashboard, but throughput had flatlined at ~800 req/s while P99 climbed past 4 seconds. The usual suspect? A thread pool sized by guesswork during a late-night deploy, six months earlier. We'd hand-tuned maxThreads to "something that felt right," and it wasn't right anymore. That's the moment I started appreciating a different default: in Solon, all of those knobs ship as 0 — meaning auto , derive...
