@petergyang Also looks like in your commenters are doing the same. Built 2-line shim code for Claude.md file to agents.md. And built agnostic .agents/skills/ as source of truth for skills.

[Michelle Lin, MD @M_Lin]

@petergyang I too was frustrated and so built an agnostic IDE structure so I can go back and forth between my repo using codex or CC. Loses some IDE-specific nuances but works pretty smoothly thus far for 2 weeks.

🚨 New @NEJM landmark trial from @PECARNteam:

PRoMPT BOLUS randomized 9,000+ children with suspected septic shock to balanced crystalloid vs 0.9% saline. No difference in kidney injury, mortality, or safety. Either is 👍.

140 unfilled EM spots in 2026 — should we be worried? 🤔

Drs. @SMKrzyz & @DrAbracadabra unpack the match numbers, the Residency CAS effect, and what it means for the future of EM recruitment 🎙️

"The jury is still out for treatment with arginine therapy." — Dr. @claudiarmorris1

The #PECARN STArT trial — a double-blind RCT testing IV arginine for sickle cell pain crises in children and young adults — was stopped early after an interim analysis suggested the primary endpoint was unlikely to be met.

But Dr. Morris isn't ready to close the book on the drug. Here's why 👇 🔗 https://t.co/zC4ZyCwlZ7

Most sepsis screening tools identify kids who already have sepsis, or who are already suspected of infection. That's useful — but it's not early enough.

This @PECARN model predicts who will develop sepsis in the next 48 hours, across the general ED population, before clinical suspicion even forms.

Earlier signal ➡️ earlier intervention ➡️ better outcomes. The biology hasn't changed. The tooling has.

Same disease. Same pain crisis. Same type of hospital. One child goes home in 28 hours. Another stays nearly 6 days.

A new secondary analysis from the #PECARN STArT trial — the largest pediatric sickle cell pain crisis trial enrollment to date — found that *where* a child receives care may matter as much as *how sick they are*.

The findings are worth a close read.

After 8 years, 240 faculty, and countless Slack conversations, we're closing a chapter—and celebrating a legacy. 🎉

📚The Education Theory Made Practical book series is complete: 8 volumes, 77 theories, all FREE.

Here's to what we built together.

@andrii_rom So far so good but it’s only been 1 week. I only need basic stats since I’m in the education space. Will check out Swetrix!

I spent 10 years frustrated with Google Analytics, never once asking: "Is there another way?" 🤔

Switched to self-hosted Umami. Clean dashboard. My data. No ad blockers stealing accuracy.

For years I had more ideas than I could build. No coding skills, no collaborators available at 2am after night shifts.

That was the ceiling. Then I started using AI as a building partner.

The ceiling is gone. 🔓

@cianmcdermott Haha, I've resolved to be an awkward learner in the AI and vibecoding space to evolve. I've been building an "operating system" for my personal and professional projects. Happy new year!

For years I built one-off, simple, no-code tools that worked but at a cost— jerry-rigged spreadsheets, screenshot-filled instruction manuals, workarounds I'd forget in 3 months.

The missing piece wasn't another app.
It was memory. 🧠
