With this influx of people, I wanna encourage people to spend their time cool and funny things instead of descending into language wars

I made a new quarto revealjs template based on Pechakucha, a presentation format where you have 20 slides that auto-advances after 20 seconds. Once started you will not be able to stop it. And it will make sure you have 20 slides whether you like it or not

It's super cool!

I used it for a bonus part TidyTuesday two years ago, making a tune out of Taylor Swift song data, saved as an mp3. Spoiler: the tune wasn't/isn't very good!

github.com/borstell/tid...

A graphic in the style of a yellowish page of sheet music. Title says "Taylor's Albums (melodized)". On the right, each album is represented by a line of sheet music. On the left, the text reads: "Each album as a single line of sheet music. The key of each track as a single note. Each note's duration as the relative track duration (z scored) across all albums."

i do something similar, but by repeating single characters instead

x <- read_csv(...)

xx <- x |>
filter(...) |>
mutate(...)

xxx <- ggplot(xx, aes(...)) +
geom_whatever()

xxxx <- ggplot(xx, aes(...)) +
geom_whatever()

library(patchwork)
xxxxxx <- xxx + xxxx
ggsave(xxxxxx)

Thank you! My hope is that this new format lets me add new content as subsections instead of having to write a full blogpost

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily

Excited to speak at our first hybrid event, meaning that all of you can watch along at home!

We have seen many people seen tremendous speed improvements by using orbital to deploy their models. I'll talk about talk about how it works, how to use it and maybe some new developments!
