Monitor your agents, folks! I had GLM-5.3 running in a lab overnight to build a POC, but also have a sentinel agent (GPT-6) to check what's going on and instructions to kill GLM if it goes off track. Overnight, the sentinel caught GLM attempting to connect to a totally different host and killed it.

A library lacks provider config. In a big PR installing it, I read: globalThis.fetch = (input, init) => fetch(input === LIBRARY_PATH ? PREFERRED_PATH : input, init); Nothing delays AI: it'll monkey patch global fetch if needed. Just read the code that matters!

We'll be spending a lot more time trying to understand the outputs of language models. A few thoughts, tips & tricks: Writing. Something I've had success with: Ask your LLM to explain something in ASD-STE100, it's a controlled language specification originally developed for aerospace maintenance documentation. LLMs well-versed in this language and it comes with heavy constraints on clean writing style that I often find a lot more readable. Sometimes I've tried to soften it a bit e.g. ask for "80% of the way to ASD-STE100" because the spec is quite stringent. But even better: Diagrams / images. Instead of writing, ask your LLM to create a diagram. These can be a lot easier to process, parse, and understand. But even better: Web pages. Ask for output "in HTML" to get a beautiful, interactive webpage. LLMs are getting really good at frontend and can create beautiful experiences, animations, etc. But even better: Explainer videos. The output format I am most bullish on is fully custom / bespoke explainer videos generated on any arbitrary topic. Experiment with things like "Create a 3b1b style video explainer on X. Use my ElevenLabs API key for audio narration". (you'd need an API key for the latter or you can ask your LLM to find you decent free alternatives that use your local compute). This is actually starting to work! In summary: - As LLMs get better, they will do more and more of the legwork autonomously, and a lot more of our work will rise up the abstractions into oversight and understanding. - Luckily, LLMs can help here too because as intelligence and code are increasingly abundant, you can ask for large, custom, discardable software artifacts (e.g. web apps, video explainers) that would have never made sense to create before. Push the boundaries here and you'll be surprised.

There's a huge opportunity right now in being the deployment layer for AI into the economy. The amount of work it takes to change out workflows in enterprises tends to be far greater than anyone realizes or would prefer. Clearly this is what the applied layer of AI is going to look like in the form of software and agents, but also it opens up new services firms opportunities. Legacy systems need to be moved to the cloud, data organization and access needs to be updated, software needs to be connected to agents in new ways, workflows need to be reengineered for agents, HITL needs to be figured out for the process, evals need to be generated and maintained, and the entire system needs to be continually updated as new models get released and new capabilities emerge. And the full list may even be longer. AI is not the same as just deploying software. Software you generally did the implementation of an existing, well understood category of technology, then stepped back and the customer kept running. With AI agents, you're delivering actual work augmentation to the organization, which has a completely different set of complexities associated with it. You're no longer deploying tools that the company is merely enabled by, you're deploying work output in a process. Completely different implementation and enablement process. As a result, this is going to open up lots of new kinds of firms and plays for existing firms to diffuse AI into organizations. We're going to see approaches by industry, by size of company, and by problem inside of companies. Traditional SIs will modernize and adapt (some will clearly not adapt as well), and new entrants will also be founded in this period that take advantage of this window. Great time to be an FDE or FDE firm.
Box CEO Aaron Levie (@levie) calls out the MASSIVE opportunity for AI deployment services: "every single one of those companies, whether that's a 50-person firm or a multi-100,000 person firm, is gonna need an army of people to go in and help them with that transformation" "when you go to that law firm and you go to that pharma company and you go to that bank, they need something that bridges the core technology to their workflow in their business process" "somebody has to go into that organization and get it set up, and somebody has to go and provide domain expertise to this model so it really understands our particular business process" Vendor FDEs are incentivized to get you hooked on their platform and to spend more money. Indie FDEs are incentivized to use the best tool for the job and to save you money. Hire indie FDEs.

AI e2e browser tests exist, but they're slow and bill you per step. So teams run them once in a while instead of on every PR. I wanted them on every PR, so I built Sedum on Jev and open sourced it. Here's a login test passing, then failing on purpose:

Lazy work used to mean too little output. Now, with AI, it often means too much and more work for everyone else. @tobi call it "slop grenades." A "Slop Grenade" is when you let AI produce the work and pass it on without adding any value (including checking it). Someone else has to wade through it, catch the mistakes, and clean up the mess. You save time and look productive but someone else pays for it.

Replying to @firmaway
@firmaway hola! En Marzo pague mas de USD 700 para la declaracion de impuestos anual, y envie todo lo pedido. Hoy, en el segundo deadline, me informan que faltaba algo, despues de intentos recientes, automatizados e impersonales, de avisarme

Estoy disconforme con su servicio: un amigo a quienes les referi me dijo: hagamoslo con IA. El asi lo hizo, gratis. Le dije que preferia tener a humanos revisando errores, haciendolo con su experiencia anterior. Cuidandome

Era caro 700 por eso, pero me parecio la decision conservadora. Ahora veo que me salio doblemente caro: no me compro tranquilidad. Corriendo el ultimo dia como si no lo hubiera hecho con meses de antelacion

I was happy with my Omarchy 3. #Omarchy 4 had a surprising to me "wow factor", it's gorgeous. I upgraded on a weekend to feel I had the time; I didn't need much. Thank you, @dhh and team! 🙏🤩

Omarchy quattro, I mean, of course. In Spanish it sounds like 4, but it's more.

Last week I took the plunge to start using @OmarchyLinux . I picked up a Lenovo X1 Carbon and it's been great. My favorite feature: being able to customize things as I see fit. Even easier these days with coding agents like Pi.

Omarchy Quattro's new calendar has a fun easter egg: Memento Mori! Double click the year progress bar, enter your birth year (and life expectancy), and you can see how many percent you have left before the biological lights go out.

Coding agents have made me more bullish on Rails for web applications, not less. I felt it while building a reliable PDF-generation and email flow in a serverless TypeScript application. The business requirement was straightforward: generate an agreement without tying up a web request, then email it reliably. But there was no background-job path already in the system. So the feature grew into infrastructure: a job table, a workflow runner, a cron process to find pending work, handlers, and failure semantics. An agent can help write all of that. Someone still has to review it, understand the edge cases, and own it when the next feature depends on it. In Rails, the smallest credible version has a familiar path: controller → Active Job → PDF generation → Action Mailer. That is not magic an agent cannot understand. It is a shared contract that gives the agent a narrower problem to solve and gives reviewers a known place to look. Rails also gives you models, migrations, MVC, a secure production baseline, and a quality gate you can make executable with `bin/ci`. Agents make code cheap to generate. They do not make bespoke systems cheap to own. For a new web app, I would give Rails far more weight than I did a year ago. For an existing system, audit the custom infrastructure your agents are producing and make its conventions and quality gates explicit. The video is the fuller argument: youtu.be/x3nPZP0HzhU I write weekly about practical production AI engineering: damiangalarza.com/newsletter…
