Introducing Lensflare – an open-source macOS development observability stack for humans and AI agents. AI agents can see your code, but not what actually happens during runtime. With AI and libraries like Effect, it has never been easier to add telemetry to your app, but the tools for working with traces locally have mostly stayed the same. Lensflare changes that by providing a fast, local-first app that listens for telemetry in real time and lets you dig deep to understand what’s happening and where. What’s more, it extends the same capabilities to Claude or Codex via a built-in MCP server. Try it out now at lensflare.dev

The <Suspense> is over. Solid 2.0 Beta is now released (next tag on npm). 🎉 github.com/solidjs/solid/…

Base UI Drawer is live. Here are some of my favourite features 🧵👇

I've been building Solo for several months, and it's out today! It's a desktop app that manages your entire dev stack. Add a project, Solo detects your processes, and you can start everything with one click. It's free! Try it today: soloterm.com

Welcome to slop development era

Me when gf leaves for a few days and I code till 4am on coffee again

Last quarter I rolled out Microsoft Copilot to 4,000 employees. $30 per seat per month. $1.4 million annually. I called it "digital transformation." The board loved that phrase. They approved it in eleven minutes. No one asked what it would actually do. Including me. I told everyone it would "10x productivity." That's not a real number. But it sounds like one. HR asked how we'd measure the 10x. I said we'd "leverage analytics dashboards." They stopped asking. Three months later I checked the usage reports. 47 people had opened it. 12 had used it more than once. One of them was me. I used it to summarize an email I could have read in 30 seconds. It took 45 seconds. Plus the time it took to fix the hallucinations. But I called it a "pilot success." Success means the pilot didn't visibly fail. The CFO asked about ROI. I showed him a graph. The graph went up and to the right. It measured "AI enablement." I made that metric up. He nodded approvingly. We're "AI-enabled" now. I don't know what that means. But it's in our investor deck. A senior developer asked why we didn't use Claude or ChatGPT. I said we needed "enterprise-grade security." He asked what that meant. I said "compliance." He asked which compliance. I said "all of them." He looked skeptical. I scheduled him for a "career development conversation." He stopped asking questions. Microsoft sent a case study team. They wanted to feature us as a success story. I told them we "saved 40,000 hours." I calculated that number by multiplying employees by a number I made up. They didn't verify it. They never do. Now we're on Microsoft's website. "Global enterprise achieves 40,000 hours of productivity gains with Copilot." The CEO shared it on LinkedIn. He got 3,000 likes. He's never used Copilot. None of the executives have. We have an exemption. "Strategic focus requires minimal digital distraction." I wrote that policy. The licenses renew next month. I'm requesting an expansion. 5,000 more seats. We haven't used the first 4,000. But this time we'll "drive adoption." Adoption means mandatory training. Training means a 45-minute webinar no one watches. But completion will be tracked. Completion is a metric. Metrics go in dashboards. Dashboards go in board presentations. Board presentations get me promoted. I'll be SVP by Q3. I still don't know what Copilot does. But I know what it's for. It's for showing we're "investing in AI." Investment means spending. Spending means commitment. Commitment means we're serious about the future. The future is whatever I say it is. As long as the graph goes up and to the right.

“We should use @EffectTS_ because we’re a bunch of dads and haven’t got much time” - @mmkalmmkal

@EffectTS_ is the most impressive technology I’ve gotten to work with. The type system, language extension, fibers, errors, dependency injection, clusters/workflows, etc. It’s nice reaching for one tool instead of multiple. Excited for 4.0 and APIs to be standardized!

I don't do Software Engineering anymore. Nobody does. It's a time when the truths of Software Engineering have been cancelled. The common ground now, pushed by the ever-growing crowd of deniers, is that we no longer need to write good software. That good code has no value. That hitting the market requires anything but good code. The truth is that Software Engineering works for everything aimed at the future. But the current industry's goals are short: build some shit, sell it, and hop on the next shit. There is no application or service creation anymore. You don't see any big useful app emerging, like 10-20 years ago. Everything in our industry today is either a short-lived grift or a heavy, buggy, corporate-driven monopolist shit that is here to enslave us. Software Engineering is no more.
