PSA: MRI Magnets are on 24/7, 365
Most hospital MRIs use superconducting magnets that carry a persistent, loss-free current locked inside coils chilled by liquid helium. That current—and therefore the main magnetic field— continues 24 h × 365 days, even when no scan is running; only the gradient coils and RF amplifiers cycle on/off during each image. Permanent-magnet scanners are likewise “on” by nature, while low-field resistive…
You're welcome
It’s heartwarming to hear “you’re welcome” in response to thank you! 

 Please say it more often. 

Ghostty
I love my brand new terminal Ghostty . Built by people who have taste. It’s replaced my long term trusty iterm2. 

 Here’s my config so far: 

 $HOME/Library/Application\ Support/com.mitchellh.ghostty/config : 
 theme = Apple System Colors Light 
 cursor-style = block 
 font-family = SF Mono 
 font-size = 11 
 shell-integration-features = no-cursor…
Disarm via Delay
Right after someone finishes a task—especially if they didn’t do it perfectly—is the worst time to tell them how they could’ve done it better. They’re still mentally engaged, maybe even a bit defensive or tired. Giving advice in that moment, even with good intent, often feels like criticism. But if you wait a few days, maybe a week, the emotional charge fades. The person is more open to hearing…
Impulse buying mitigation
I’m an impulse buyer so I need to be able to undo . Sellers that allow returns for change of mind are essentially providing an undo feature. Some of them that I use often are: 

 
 Apple (14 days, can unpack and use) 
 IKEA (can return unused for a year!) 
 Amazon 
 Decathlon

Building Hello World for ESP32-C6 using ESP low level SDK
Sleepy End Device (SED) is a device that’s sleeping most of the time and has very low power consumption — think running on a single AA for a year! 

 Here’s end-to-end getting things setup ( ref1 , ref2, ref3): 
 brew install cmake ninja dfu-util python3
git clone -b v5.4.1 --recursive https://github.com/espressif/esp-idf.git
 cd esp-idf
./install.sh esp32c6 #…
Simple Zigbee Development
Finally a cheap and simple way of making Zigbee devices using Arduino and ESP32-C6 . 
 Arduino Setup 
 
 Add https://espressif.github.io/arduino-esp32/package_esp32_index.json to Arduino Settings -> Additional boards manager URLs and refresh the index (in the new IDE, that’s ⌘+Shift+P and select “Arduino: Update library index”). 
 Go to board manager and install…

# General Principles 

 Given any NON - TRIVIAL task : 

 1. Think about how to make the requirement less dumb . Do not assume the 
 user knows what the most optimal / right requirement is . 
 2. Delete code . If you ' re not adding 10 % back, you haven ' t removed 
 enough . 
 3. Simplify and optimize the design . Best code is no code . 
 4. Accelerate the…

TinyGo and gopls headaches
I had trouble getting VSCode using Go lang server to resolve all modules properly for a TinyGo project.

	 'tinygo.org/x/bluetooth' 
 ) 

 var adapter = bluetooth . DefaultAdapter
