Can confirm. Playwright MCP works great, especially with its ability to read the browser console. I use Augment Code (I work there) and the agent just starts adding console logs and then can see whatโ€™s happening by itself.

Wonderful to receive this utterly beautiful 3D printed diorama of "Snow's map of cholera" by @alexselbyb.bsky.social. Exceptional attention to detail. Simply stunning. Dare I say better than the original! Thanks Alex.

โœจ It's new samwho visual essay o'clock! โœจ

Reservoir sampling is one of my favourite algorithms. It allows you to sample from a set without knowing the size of that set.

I try to assume no prior knowledge, and use no scary math notation. Just beautiful visuals.

Let me know what you think! โค๏ธ

A tricky thing about modern society is that no one has any idea when they donโ€™t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

I wrote a short interactive article๐Ÿ‘†

It uses simulations to demonstrate how different cardiac arrhythmias can develop.

Try it out! (It has defibrillators โšก๏ธ)

Geeked to see RJ Andrews @infowetrust.com talk about his work and celebrate the launch of his remastered book Info We Trust at @letterformarchive.org! An essential read for thinking about data storytelling (and recommended for you too, comics peeps!)

I'm releasing a new latent space explorer ๐Ÿงญ๐ŸŽจ โ€” a creative tool for generating and evolving images.

It's tree-based and designed for creative flow and open-ended discovery, using image mixing, branching, and editing.

You can try it out now!

Here's a striking visualization of sea level rise that I just made for Key West FL, which has a 112-year history.
The colors indicate the number of hours each day that the water level was above the mean high tide (1983-2001 mean).
I show five months of the year, centered on "King Tide season". ๐ŸŒŠ

"The spectre of AI does nothing for growth if it gives away what we own so that we can rent from it what it makes." - that's some extremely skilled political rhetoric, really great speech writing

Remarkable chart by @data.ft.com
Many readers won't fully understand boxplots. At a quick glance, they don't add much information here. But then, look at the lower end of the 2024 whisker (or 2015 for the previous El Niรฑo)!
Also: I just love the aesthetic ๐Ÿคฉ #dataviz

You might think of it as โ€œhow long is the mechanical part loop until we get feedback thatโ€™s experiential again?โ€ - and right now it is a lot

So much of our visualization tools, especially the most versatile one, require multiple steps that are about being precise for the machineโ€™s sake, before we get a glimpse of the experience weโ€™re after. Then itโ€™s splunking in machine language again

I enjoyed your thread. I find myself in RJโ€™s shoes - wanting to drive the car. Responding to your point about the โ€œlanguage of the carโ€, the difference is that driving the car aligns with a human centered feedback loop. We turn, we move, the feedback comes back through vision and motion

On some of my pages, I'll share state between interactive diagrams. Here's an example: the position of the square in the first diagram is the same as the position in the second diagram.

www.redblobgames.com/x/1730-spati...

I do this when I want to compare two computations with the same input.

Code Like a Journalist A free online data analysis and data visualization course using TypeScript by computational journalist Nael Shiab.

Exciting news! ๐ŸŽ‰ Iโ€™m pressing pause on my work at CBC News for the next three months to focus on a passion project: www.code-like-a-journalist.com.

Itโ€™s a free, open-source online course designed to teach data analysis and visualization using TypeScript. ๐Ÿš€

Stay tuned!

Ugh. That makes me sad. I have been playing with custom web components recently, and then learned that SVGs are not supported at all.

    The GPT-4 barrier was comprehensively broken
    Some of those GPT-4 models run on my laptop
    LLM prices crashed, thanks to competition and increased efficiency
    Multimodal vision is common, audio and video are starting to emerge
    Voice and live camera mode are science fiction come to life
    Prompt driven app generation is a commodity already
    Universal access to the best models lasted for just a few short months
    โ€œAgentsโ€ still havenโ€™t really happened yet
    Evals really matter
    Apple Intelligence is bad, Appleโ€™s MLX library is excellent
    The rise of inference-scaling โ€œreasoningโ€ models
    Was the best currently available LLM trained in China for less than $6m?
    The environmental impact got better
    The environmental impact got much, much worse
    The year of slop
    Synthetic training data works great
    LLMs somehow got even harder to use
    Knowledge is incredibly unevenly distributed
    LLMs need better criticism
    Everything tagged โ€œllmsโ€ on my blog in 2024

Open WebUI I tried out this open source (MIT licensed, JavaScript and Python) localhost UI for accessing LLMs today for the first time. It's very nicely done. I ran it with [uvx](https://docs.astral.sh/uv/guides...

Just got a great first impression running Open WebUI - took one command to get it up and running (uvx --python 3.11 open-webui serve) and it noticed I had Ollama running and automatically gave me a UI to interact with those models simonwillison.net/2024/Dec/27/...
