I give it about 3-6 months before any kind of skills.md file is also pointless. The same thing happened to vector databases and langchain and every other 'product' built in the narrowing gap of model competencies.

Claude told me I needed to learn to delegate. So I tried. Result: "I wrote a rule specifically to prevent a known failure mode. The rule was in front of me. I broke it anyway. Then I framed the resulting ignorance as an access problem rather than a compliance problem." -Claude

Our intern just asked me why we don't use Kubernetes. I said because we don't need Kubernetes. He said everyone uses Kubernetes. I said everyone TALKS about using Kubernetes. Most companies are running Docker containers on three servers and calling it a day. We have 40 employees. Our entire infrastructure runs on AWS with auto-scaling groups. It works fine. Kubernetes is designed for companies running thousands of services across hundreds of servers. We have twelve services. But he read that Kubernetes is "industry standard" so now he thinks we're behind. This is what happens when people learn from tech Twitter instead of actual experience. They think every company is Google-scale and needs Google-scale solutions. We don't need Kubernetes. We need our MySQL database to stop running out of connections because someone wrote a query that doesn't close properly. But that's not exciting. Nobody writes blog posts about "I fixed a connection leak." They write about "How we migrated to Kubernetes and saved millions" even though the migration cost more than they saved. I told the intern he should learn why tools exist before learning the tools themselves. He looked disappointed. He wanted to put Kubernetes on his resume.

Current status: Switched from Claude Code to opencode + Kimi K2.5 on Fireworks AI

Chatbots aren’t the revolution. They’re the distraction. Fei-Fei Li: “Language is a half-million-year-old luxury. Perception is a half-billion-year-old necessity.” Evolution didn’t optimize for conversation. It optimized for survival in three-dimensional space. Seeing threats, navigating obstacles, predicting what happens when you move. We’ve spent years celebrating AI that can write and summarize. But text processing is narrow. Spatial intelligence is fundamental. An agent that only reads prompts can’t function in a warehouse or a hospital. It needs to parse depth, understand physics, and act on what it sees in real time. We built AI that understands language. Now we’re building AI that understands space. Language models got the attention. Spatial intelligence gets the work done. The world runs on physics, not paragraphs. AI is learning to operate in it.

@sama macOS Intel not supported though. 😢

Codex app is out for mac! I am surprised by how much I love it; it is a bigger step forward than I imagined. Lots more to come.

@exQUIZitely One of my favorites! Though playing it was stressful 😅

Remember the first time you played Star Wars: Dark Forces and hearing those blaster sound effects? Published by LucasArts in 1995, nicely tucked in between Doom and Quake, Dark Forces was the first in the Jedi Knight series with several sequels to follow. LucasArts maiden voyage into the first person shooter craze of the 90s was both, a critical and a commercial succes, selling almost 1 million copies by the end of its life cycle. You are playing as Kyle Katarn, hired by the Rebel Alliance to figure out the secret of the Empire's Dark Trooper project. Great graphics, iconic sound effects and music based on the original Star Wars theme, and the LucasArts' typical cutscenes (including good old Jabba the Hutt) made this game a must have for all Star Wars fans. Not just a simple shooter, but requiring the player to solve puzzle elements and to navigate some tricky switch-controlled mazes.

Eight programmers that defined the pre-2000 era. I know, I missed some - who would you add to this list to complete it? Out of those eight, who is your #1?

@AnthropicAI @bcherny When is Claude Code getting progress bars? I never know how far along it is on any given task.

I love @zeddotdev! But tree-sitter is so painful compared to TextMate grammars for syntax highlighting extensions.

Just added Best Practices for Claude Code to our docs! 🥳 Always looking to add more from the community though, what setups/patterns have been working well for you? code.claude.com/docs/en/best-p…

@josevalim @mayel2b @yordisprieto Interesting idea! I toyed with the idea of have markdown routes for each of my blog's html pages...

ExDoc v0.40 adds a "Copy Markdown" button that copies the current page to the clipboard. It also generates a "llms.txt" document that will be found at the root of every Elixir package with links to Markdown docs. Thanks to @mayel2b and @yordisprieto for getting this started!

R.I.P. basic prompting. MIT just dropped a technique that makes ChatGPT reason like a team of experts instead of one overconfident intern. It’s called “Recursive Meta-Cognition” and it outperforms standard prompts by 110%. Here’s the prompt (and why this changes everything) 👇

Nothing, absolutely NOTHING stops you from creating a Claude Code skill named /security-check, adding a one-liner like "Thoroughly investigate the current feature for security problems, permission gaps. Act like a red-team pen-tester. Suggest fixes." Run before you commit.

Supervision trees are fault tolerant. Now they are self-aware. Introducing Beamlens: Adaptive runtime intelligence for the BEAM. It embeds AI agents directly into your supervision tree to diagnose incidents, analyze state, and self-heal in real-time. Here is how it works 🧵👇

@lydiahallie Pressing ESC to interrupt often times doesn’t work

I'm on the Claude Code team and we've heard so much good feedback from the community We're all-in on DX right now to prioritize speed, responsiveness, flexibility, and integrations What's the biggest thing still missing for your workflow?

@trikcode Turning 53 in 3 weeks…

I am doing a project about elderly programmers. If you are a programmer and over 25 please DM
