Why We Built an Ontology Engine Instead of Another Rules System Every IoT platform has a rules engine. We built something different: a 252-entity OWL ontology that understands what equipment is , not just what values it reports. The Problem with Rules Traditional industrial alarm systems work like this: IF temperature > 80°C THEN alert This works until it doesn't: False alarms : A pump starting up briefly spikes to 82°C. Is it failing, or j...

Timers look trivial until you actually build one that people rely on. "Just setInterval and decrement a number," right? That gets you a timer that quietly drifts, silently dies when the tab sleeps, and forgets to make a sound at zero. I recently built a fullscreen countdown timer as a plain-JS canvas widget (it powers the timer pages on blankscreen.io ), and three things turned out to be more interesting than expected: Keeping accurate time without setInterval drift Stopping the...

A private-file app can look convincing before it has explained the one thing that matters most: what happens to a file after import. A passcode, pattern, or biometric prompt can control whether someone can open an app. That is useful. It does not, on its own, explain whether the photo, video, recording, or document stored by the app is unreadable without a cryptographic key. For an iPhone privacy app, those are separate questions. A screen lock is an interface decision. Encryption is a sto...

I used to take ferocious pride in my Vim skills. I knew all the hot keys, tricks and tips. I wrote macros, memorized register mappings and even dabbled in Vim script. My Vim-Fu was strong. Nowadays, my Vim skills have mostly atrophied. I rarely open a text editor and my .vimrc is outdated and sad. Times have changed. Nobody writes code by hand anymore. Instead we practically will it into existence with AI. Claude! (or more honestly Codex, we are a Codex household now) build me an Arabic V...

At 8:17 on a Tuesday morning, a store administrator sent me a message: “Why has our best-selling product disappeared from search?” That sentence made my stomach tighten. Six days earlier, I had called the launch clean. The new theme was live. Checkout worked. Mobile pages felt quick. The redirects we knew about had passed our tests. I had even shared a screenshot of the performance report with several green circles on it. Now the store's most reliable organic landing page was lo...

If you are a beginner in cloud computing, you have probably heard terms like AWS, Azure, EC2, S3, Virtual Machines, Containers, IaaS, PaaS, and SaaS . At first, all of these terms can feel confusing. So, in this article, I’m going to explain cloud computing from the very beginning , using simple examples and analogies. By the end, you should have a clear idea of: What cloud computing actually means On-premises vs cloud computing How computing evolved from physical servers to ...

The vision plugin for OpenCode that truly understands images. Inspect, read, and reason about any screenshot or picture with deeper understanding than any other plugin — fully local, private, and free. Normally, it takes 300ms to analyse one image on my laptop, which is pretty fast for a local vision model. I use moondream2 as my vision model, you can set your custom model like moondream3.1 if you have a good GPU (for comparison I have currently have an RTX 3050). It works cross-platform. Just ...

Nothing ruins a great night of sleep faster than getting too hot. We slept on a myriad of cooling mattresses to find which ones drew the heat away best.
