Your post reminded me of a video from at least 2009, possibly earlier. Yes it’s somewhat offensive. Yes I’m a bad person and still laugh at it. www.dailymotion.com/video/x2okwn4

TIL that splattering your scrubs with beet juice at lunch leaves you looking like you were at a VERY bad C-section. And it doesn’t blot out. So now I look like an axe murderer, taking care of the babies.

Forever ago I really enjoyed SimAnt. Two of my favorite non-fiction books include EO Wilson and Holldobler’s Journey to the Ants and The Leafcutter Ants Will have to check this out. Is it more game or biological sim? 🐜

In my office, I still have “books” (those things made out of trees) that I learned PHP and Perl from. (My clinical calculator website is fully hand coded in PHP…) Maybe I should see if my laserdisc player still works.

Encouraging a kid who decided to get vaccinated, in my own apparently strange way. #PedSky
Former pediatrician here (now just newborns) — congratulations and thank you.

When you feel sore and achy afterwards, remember that it’s because IT’S WORKING! Your body’s immune system is going “what the heck is this stuff?!? I’m going to learn to kick the sh*t out of it if I ever run into it again.”

Whenever I got my shots and I DIDN’T feel sort of crummy the couple of days afterwards, I was worried the shots weren’t working :)

You do have to give Anthropic credit here. It is rare for a lab to publish data questioning its own tools. Meta constantly buries internal findings that challenge their business model. This kind of transparency is uncommon and should be encouraged instead of dog-piled. Link to the full study:

Really important research out of Anthropic: In a RCT study, they found AI coding assistance resulted in a 𝟏𝟕% 𝐝𝐫𝐨𝐩 in mastery for users. While tasks were slightly faster, offloading thinking to AI stunted skill growth. Using AI to explain code, rather than just write it did help with retention.

Thank you, Massachusetts Department of Public Health. #PedSky
Massachusetts Department of Public Health (DPH) 
Guidance on Recommended Reference Materials for Pediatric Immunization Schedules  
January 2026 
 
The Massachusetts Department of Public Health (DPH) is issuing this notification to inform clinicians of a change in recommended reference materials for pediatric immunization schedules. 
 
DPH has a longstanding and ongoing commitment to promoting evidence-based immunization practices that protect communities from vaccine preventable illnesses.  Following a review of recent changes to the Centers for Disease Control and Prevention (CDC) pediatric immunization schedule, DPH now recommends that clinicians in Massachusetts use the American Academy of Pediatrics (AAP) Recommended Child and Adolescent Immunization Schedule  as the primary reference for the routine immunization of infants, children, and adolescents. 
 
DPH recognizes the importance of clear, consistent, and evidence-based guidance to facilitate safe and effective vaccination practices. AAP is a national professional organization representing pediatric physicians, and its immunization schedule is developed by pediatric experts and updated regularly to reflect current evidence and clinical best practices for immunizing children and adolescents. The AAP immunization schedule aligns with science-backed pediatric standards of care and provides detailed guidance that supports clinical decision-making in pediatric settings. 
 
Clinicians should continue to follow all applicable state requirements, including the immunization requirements for school and camp entry (aligned with AAP recommendations), and reporting obligations, including documentation of administered immunizations in the Massachusetts Immunization Information System (MIIS). 
 
DPH will continue to monitor national immunization policy updates and will communicate any additional guidance as needed. 
 
Thank you for your continued commitment to protecting the health of Massachusetts children and families. …
