For geospatial data, it's 3x-5x faster to join and count the trees in each Montreal neighbourhood.
I started working on the library 3 years ago. I was tired of switching between R/Python/JavaScript in my projects and wanted to keep it to TypeScript from A to Z. 🤓

So happy to see how fast the TypeScript library simple-data-analysis has become for tabular and geospatial data! 🤩
It's now processing data 6x-12x faster than traditional R and Python solutions in my little test in which I crunched a 1.7 GB CSV file.

My most popular interactive @observablehq.com notebook, Math for Journalists, just got a fresh update! 🧑🎓
👉 Sample size and confidence: I explain how sample sizes work, like in a survey.
👉 Tests for statistical significance: I break down what "statistically significant" means.

I asked Gemini-CLI to fix mistakes and add examples to the documentation of the open-source library journalism. It updated 58 files and did a pretty good job in half an hour. I used the free tier, but the @simonwillison.net LLM pricing calculator estimated the cost at $6 USD! Very impressed. 😶

New project! I've always felt climate projections were a bit too abstract. To make them more concrete, I identified North American cities that already experience the projected temperature and precipitation of Canadian cities. And the result is... 😳

Bad air quality caused by Western wildfires for 54 communities this morning, mainly in Southern Ontario and Quebec. And summer hasn't even started yet... Link to our climate dashboard in the comments.

Just updated our Climate Dashboard this morning to add air quality warnings. The smoke from all of those fires out West is being pushed East by the winds. It's pretty bad to breathe in Northern Manitoba and Ontario right now.

Back in March, I attended the fantastic NICAR session "My first LLM classifier" by @palewi.re and @dwillis.bsky.social.
It was eye-opening, but all in Python. And you know I love TypeScript! 🤓 So, I added new features to the SDA library, and Ben kindly let me reproduce his tutorial!

Got bits of code you keep copy-pasting from project to project? You should turn them into a library!
And guess what? You’re in luck for two reasons:
- It’s never been easier to publish one with @deno.land and @jsr.io 🚀
- I just published a new lesson showing you exactly how to do it 💡

You cracked the data. You uncovered the findings. Now let’s publish your own website for free with GitHub Pages! 🌍📊
Trust me, it’s easier than you think.

I used to set alarms to run my web scrapers manually, every day, on my computer. I didn’t know any better! 🥲
But now I do. Let me show you how to run them on a schedule in the cloud with GitHub Actions, for free. 😏

Intimidated by GitHub? I’ve been there.
So let’s take a friendly walkthrough together in the new lesson I just published. I’ll show you how to use this amazing platform and avoid pushing your password live. 😅

As a journalism grad, I struggled with Git for YEARS. For longer than I’d like to admit, it felt easier to keep my code on Google Drive instead of GitHub. 😅
So I’m kicking off a new section on Code Like a Journalist all about Git and GitHub!
First lesson linked below — with more on the way! 👇
