ferrerallan Your app needs to send a PDF to a customer on WhatsApp. You read the Meta docs, they look short, so you block an afternoon. Four days later you have three WhatsApp Business Accounts, a phone number stuck in a state nobody documents, and messages that return HTTP 200 and never arrive, with no error … Read more
You have a landscape video and you need it vertical for Reels. You center crop it, look at the result, and it is fine. Then the person takes two steps to the left and spends the next fifty seconds talking to the edge of the screen. Fine, you will just follow the speaker automatically. That … Read more
You kick off a fine-tuning run on a foundation model, watch the GPU meter climb, and pay for every second of it. Somewhere in that run, a decent chunk of compute is going into layers that have nothing to do with your problem. You do not know which ones, because nobody ever told you to … Read more
Somebody opens a photo in Photoshop, erase a tiny scratch in the background, save, and post it online thinking nobody will notice, and nobody notices, looking at it with the eye. Except the camera noise noticed, and it is going to tell. This post is about how a classical signal-processing technique, with zero lines of … Read more
The mysqldump finished without complaining about a single line, and for a second you get that calm of someone who thinks the job is done. Then the file gets pointed at the shiny new RDS instance, enter is pressed with confidence, and the import dies on the very first function with an error about a … Read more
In this post I describe how I create a on-premise solution to handle with videos that needs scenes segmented, faces identified, subtitles generated, thumbnails picked, metadata pulled into the catalog. This post is about how we stopped trying to win that math with people and started winning it with our own AI. TL;DR: How SOFA … Read more
You spent three sprints building the screen. Forms, dropdowns, a five-step wizard with a progress bar you were weirdly proud of. Then a user ignored all of it, pointed an AI agent at the same API your screen sits on, and finished the job in an hour while you were still in standup. This post … Read more
Today, it’s entirely possible for (almost) anyone to build an AI agent that pulls data from an MCP, reshapes a JSON, and earns applause as quickly as it breaks in production. The person is left staring at a workflow they built but never truly understood, supported by a tool whose limitations they never learned. The … Read more
For years I was the person keeping an ASP.NET WebForms app alive. It ran the whole business: sales reps, their orders, commissions, the companies they represent. It also ran exclusively on Windows, leaned on a DevExpress control suite from 2011, and printed its reports through an engine that refused to build anywhere except one very … Read more
You are handed a brain MRI and a deceptively simple question: how much multiple sclerosis is in here? The lesions are right there on the FLAIR scan, bright little blobs scattered through the white matter, but “right there” is not a number. Counting them by hand across 181 slices, for five patients, is how you … Read more
