#AdventOfCode Day 06 - both parts 🥳💃
Knew I wanted to do today's in #rstats instead of #pydata as soon as I saw it. Nice wrangling. Some duplication in code, but don't have time to reduce. Pun intended.

#AdventOfCode Day 05 Part I only in #pydata

#AdventOfCode Day 05 Part I only in #pydata
#AdventOfCode Day 02 Part I only.
Not sure I could do Part II even if I was using beloved #rstats, and not struggling through with #pydata.
Anyway, tomorrow is another day. Happy to do what I can given the time restrictions that I have 🚸

It's most wonderful time of the year - #AdventOfCode Day 01🎄
Having abandoned #pydata in favour of #rstats 13 years ago, I am keen to give our relationship another go. Especially as I left pre-pandas 🐼
Will revert to R as soon as the going gets tough. Probably in a day or two 😅

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more:

Mastering typefaces and fonts in #rstats has always been harder than it should.
I have tried to collect much of my relevant knowledge in this deep-dive blog post so you can spend your time picking the right typeface instead of cursing at the computer

Fonts in R
Taking control of fonts and text rendering in R can be challenging. This deep-dive teaches you everything (and then some) you need to know to keep your sanity

Emil!!! I think you're my guardian angel. Just today I was completely puzzled by a Shiny app that loaded in <2 seconds for me, but up to 40 seconds for users! Used profvis and reactlog to no avail...

I've been thinking about *where* I've learned various skills that I have found extremely helpful in my life/career and perhaps the top 3 for me are:
- formal education in physics & astronomy
- stint in an improv troupe
- training and then experience as a teen leading a Bible study group

Playing in orchestras and ensembles - being at the right place at the right time, bringing the right music and wearing appropriate attire. Things similar to these now take up less headspace than they would without the extensive experience.🎻

Part II runs 3x faster than Part I 😉
First time using memoise although that's not the speed-up, as using that in both parts. Even the compulsive R-Restarter that I am (command+shift+R), it still bit me a few times 😂
Coding is joy 🥳🎄

fill() probably the most useful function here. First time using co-pilot, it was very helpful with the first regular expression, but weirdly lost the plot when I asked for the second one.
