This thread is so great! 🤩 To avoid annoying resizing, figured I'd mention an alternative to {ggview}: {showtext} can resize all text to a specific dpi Text is the part that I find I have to fiddle with most when saving #ggplot2 plots, so this usually works for me 😀 #rstats #dataviz
library(showtext)
showtext_opts(dpi = 300)
ggsave(
  plot = my_plot,
  file = "file_name.png",
  width = 6,
  height = 4,
  dpi = 300
)

Nic ( @niccrane.bsky.social) taught us all about FREAKING PARQUET FILES on the #DSLab, which are wayyyyy cooler than I realized. Parquet files: Preserve data types Are fast & small Are column-oriented so you can read just 1 col if wanted! & Positron displays'em out-the-box! ▶️ youtu.be/2mQ4kc9J9uQ

Anyone else's house experience The Witching Hour? In which all animals and humans and appliances go wild at the same time? Overstimulated is not a strong enough word. I need a much punchier one.

Samsung... why you like dis? Why only display the "set" or target temp (twice) instead of the actual measured temp, which you DO have a json variable for, which I can clearly see in the advance web app browser version of your dumb app 😂 Where do I file a GitHub issue?? @sumsung.bsky.social

Husband and I have been together 20 years next month, and we've never - not once - had a fridge with an ice maker in it. Today, we say goodbye to a trusty old fridge and we get a new one. Now taking bets on how soon our brand new appliance breaks 😂 Also, the water line behind our fridge exploded 🫡

The last tiny bit of a Mac OS update is always such a tease. It looks small. It says 5 minutes. But then those 5 minutes last forever, and my next meeting is staring me down on the calendar while I reconsider my life choices.

There are wonderful humans in this world. They come in all sizes, patterns, colors, textures, and shapes. They have experiences that shape them, and those experiences probably don't look like the ones that shaped you. There are a billion+ ways to be a person. Be curious! Listen and see. Think!

Today at #positconf2026, I went rogue and interrupted the evening keynote with a nonsensical virtual poll because of some (hilarious?) technical issues 👀 You had to be there virtually, I promise it would have made sense. ANYONE WOULD HAVE DONE THE SAME! They haven't fired me yet 👉🏼👈🏼

I've been a huge Beatles fan since I was really little. Half my ill-advised internet passwords were (are? Internet is forever?) Beatles references. It's not something I talk about, it's just something that is. I love the Beatles 🤷🏻‍♀️ What's something you don't talk much about, but just IS for you?

So I took the LinkedIn app off my phone (thanks for the nudge towards my own goal, @steffilazerte.bsky.social !) because I have to use it for work and have been wanting to separate life/work more. Gotta say, my relationship with it shifted immediately. Better boundaries FTW 😤😤😤

Today was cursed. CURSED. Everything went wrong. Everyone needed something from me when I had no answers for them. Everything I did was wrong. I ran over a curb. My baby didn't cooperate with the ultrasound. I failed my first gestational diabetes test. I'm anemic again. I didn't get the email out.

My brain has really clocked out for the day, but I have at LEAST a few more hours of work to do. My brain, like a lot of brains, doesn't have more than 2-4 hours of "focused work" in it - whatever the heck that means for an ADHD brain (eye roll at capitalism) - & pregnancy has truly shortened that.

In #Positron or #VSCode, have you tried using the Native Tabs setting? `"window.nativeTabs": true` in the settings.json will get you there. You can switch between different projects in different tabs! Caveat: it changes your custom title bar! 😩 #databs #rstats lucasprag.com/posts/underr...

When someone's feedback or advice to you amounts to, basically, "be less like you," it *should* be easy to ignore, right? But we know it's not really that easy, and that it can cause us to doubt ourselves. Returning to ourselves, questioning feedback a little bit, it can be an act of resistance ❤️

No one has benefitted more joyously from my pregnancy cravings than my husband I'm a frugal person, & we have spent many a year only eating at a restaurant once a week or less Now, he makes it his duty to fulfill any craving, & he's LOVING getting to partake of all this "outside" food 😂

Watching my creative husband be forced to use AI-generated images, text, & voices at work really hurts my soul. He's got a BFA & a mass comm degree. He's been crafting courses for decades. He LOVES design work, & now he's unable to design, it's all "use AI if you want to keep your job" at work

A widening dividing line appeared this past year between people who used to find joy in their jobs having that joy stripped away by AI, & people who were sort of so-so about their jobs now being wildly jazzed about AI, & I thought I understood what made each camp feel that way, but I was wrong.

Husband & I met working in restaurants. We've been lovingly saying, "Heard, chef" to each other for 20 years. Brother was a line cook. Now, I hear normies out in the wild saying it & I'm like, oh! Did you work in restaurants, too? And they say, "No...? I watched The Bear?" 😂 (which I haven't seen!)

I asked a few poll questions on the #DSHangout today & I was very happy to find I was in really good company w/ LOVING TO BE NERD-SNIPED 😂😍 Would love to know where people land on these, bc my answers are: - yes, nerd-snipe me - yes, I track but then don't analyze 🙈 - not anymore! #databs #rstats
Three stacked poll screenshots on a dark blue background. 

Poll 1 asks, “Do you love being asked for help by coworkers?” Results: 85% said “Yes! Nerd-snipe me!” and 15% said they’d rather be left alone to get their work done. 

Poll 2 asks whether people track personal data such as sports or sleep. Results: 41% don’t track their own data, 38% track it but don’t analyze it themselves, and 22% both track and analyze it. 

Poll 3 asks about anxiety around sharing code or screen-sharing while coding. Results: 48% currently struggle with this, 39% struggled early in their careers but not anymore, and 12% never struggled with it.

Be around kind nerds. It's the way. I love just learning new and random things that I'd likely never otherwise bump into! Just casually chatting with an #rstats or #python data person will inevitably surface a package, a library, a method, SOMETHING I've never heard of and it's the besssstttt.
