Hey R and Python folks at #NICAR26 looking at coding agents for data analysis: Databot from Posit (formerly RStudio) is another option. It's an agent for the Positron IDE specifically designed for data work.

See a demo from September's Posit conference:

Writing a #Python module? Want to control which names are exported via "from .. import *"?
Define __all__, a list of strings indicating which names will be exported via "import *":
x = 100
y = [10, 20, 30]
z = {100, 200, 300}
__all__ = ['x', 'z']

Hey all, sharing a couple blog posts here about domain-driven design (DDD) & scientific (#python) software:
https://blog.nicholdav.info/posts/2026-03-06-domain-driven-design/
& how I use it w/VocalPy:
https://blog.vocalpy.org/posts/2025-12-19-domain-driven-design/
Would love to hear what ppl think.
Esp. curious to hear from folks who know CompSci history + teaching well, and/or who do social sci around SWE -- are there reasons DDD is not more widely known? @gvwilson @dabeaz @Felienne @grimalkina
(big thx to @us_rse @pyOpenSci ppl who gave feedback)

Pinsource, a fork of my previous application called #hcsr04sensor, is a #python library for interacting with Ultrasonic Sound sensors on arm boards like a #RaspberryPi.
Unlike hcsr04sensor that uses #RPi.GPIO , Pinsource uses #lgpio and should work on a #RaspberryPi5 . Problem is I don't have a Pi 5 and have no immediate plans to get one. If anyone has an #HCSR04 or #JSNSRT04 ultrasonic sensor and a Pi 5 I would appreciate a quick test.

CryptoBuddy или как мы с другом решили сделать переписку секьюрной
Всем привет! Моя первая статья тут, просьба строго не судить :-) Предыстория Когда-то давным-давно, в прошлом десятилетии, я учился в одном техническом университете по специальности "информационная безопасность автоматизированных систем" и один из предметов, который меня заинтересовал, был криптография. В то время для меня это был какой-то вид магии, сверхспособность - возможность передавать информацию так, чтобы ее понял только тот, кому она предназначалась. Однако после учебы, столкнувшись на практике с данной областью ИБ, романтика ушла на второй план, и осталось практическое понимание необходимости использования криптографии для обмена "конфиденциальной" информацией. Там, на месте работы (одна большая государственная организация), где использовал криптографию в практическом аспекте, и познакомился со своим другом. Почти 9 лет прошло) Потом я перешел работать в SOC, и с криптографией взаимодействую не так часто, однако идея возможности передачи зашифрованной информации все еще была в уме. Поэтому в определенный момент решил реализовать это на практике, создав небольшого локального помощника в данном вопросе.

I love Bash. I used to write tons of Bash. There is a lot of Bash in my life, even to this day.
But here's my life now:
* Bash holds some stuff together (small stuff: usually setting variables, aliases, and/or piping together a few CLI tools. See https://github.com/wolf/dotfiles/tree/main/shells/dot-config/shells/topics for examples)
* Zsh is good at doing stuff when I type, so that's my login shell
* If I have to do something interesting, why not just a Python script? In modern times, with a `uv` shebang line and self-specified dependencies ... the only externally visible additional requirement is `uv` itself (you don't even need Python). Just like a shell-based answer: you end up with a single stand-alone file
I'm not going to argue about "but you have to install `uv`". You do you.

Python Tip: os.scandir() Speed
import os
# 20x faster than os.listdir() for stat operations
for entry in os.scandir('/path'):
if entry.is_file():
print(entry.name, entry.stat().st_size)
os.scandir() caches file metadata during iteration. Up to 20x faster than listdir() + stat() calls.
