View off the deck. It doesn’t get much better. Owls, hawks, woodpeckers, herons, kingfishers, a host of local and migrating song birds, deer, coyotes, raccoons, squirrels, and chipmunks. All in this view. And some noisy neighbors banging on stuff.
A wooded scene in early autumn, with tall trees in mixed green and golden-yellow foliage. Sunlight filters through the branches, and a small creek runs along the forest floor covered in fallen leaves.

I don’t want to come back inside
Looking down at my boot-clad feet standing on rocks in the creek. Warm sunlight across the scene. The creek surrounded tall deciduous trees whose leaves are turning yellow.

true, according to Max
gray tabby cat with white paws and a white belly is sleeping curled up on an orange office chair. The cat’s head rests on one front paw, and its tail hangs slightly off the seat. The chair is set on a beige carpet, with part of a blue blanket draped over its back.

do you even spelling bee?
bee <- function(max_vowels = 2) { vowels <- c("a", "e", "i", "o", "u") seven <- sample(letters, 7, replace = FALSE) num_vowels <- length(intersect(seven, vowels)) while (num_vowels == 0 || num_vowels > max_vowels) { seven <- sample(letters, 7, replace = FALSE) num_vowels <- length(intersect(seven, vowels)) } pattern <- "\n\n %s\n%s %s\n %s\n%s %s\n %s\n\n" cat(sprintf(pattern, seven[1], seven[2], seven[3], seven[4], seven[5], seven[6], seven[7])) } bee()

I follwed that up with this prompt and got really good results.
Look at the case names column and the full name column. Tell me where a defendant is listed more than once for the same case but at different times in the same case. For example, if a shooter is recorded here twice, once for their indictment once for their sentencing, I want to know that because I only want to count them once. Or, if a defendant appears twice because they were indicted at two jurisdiction levels (federal and state) I want to know that too.

I don't have the exact prompt, but it was something like this (also pasted in the image alt text).
I need to fix data quality issues with these cases. Examine the case names column and look for typos and other naming inconsistencies. Also identify cases that are missing names or may have odd placeholder names.

I like Claude Code for this kind of thing. I doubt I would have found and fixed 151 data cleaning issues in 13 minutes.
⏺ Task(Analyze case name patterns) ⎿ Done (15 tool uses · 48.9k tokens · 12m 58s) ⏺ I've completed a comprehensive analysis of case names across all three CSV files (8,707 total cases). Here's what I found: Key Findings 151 unique issues identified across these categories: Major Issues: 1. United States typos (22 cases): "United State", "United Staes", "United Sates", "United Statse", etc. 2. State name typos (55 cases): Virgina, Tennesse, Georiga, Conneticut, Illnois, Minneosta, Pennsylvannia, etc. 3. Concatenated "of[State]" (16 cases): "ofMassachusetts", "ofVirginia", "ofPennsylvania" 4. "American" instead of "America" (4 cases): "United States of American" 5. "vs" instead of "v." (13 cases): Mostly Oregon and North Carolina 6. Whitespace issues (23 cases): Leading/trailing spaces 7. Multiple consecutive spaces (4 cases) 8. Placeholder values (13 cases): "Unknown", "Data not available", "W" Your Current Code Coverage: ✅ Already handles: Some "United States" typos, "Ofmassachusetts", Tennessee variations❌ Missing: Most state typos, whitespace issues, "vs" patterns, "United States of American", placeholders I've provided a complete updated cleaning code block that fixes all 151 issues. The code is ordered properly (whitespace → concatenation → spelling → separators → standardization) and includes all the fixes your current code has plus the new ones needed for the two additional datasets.

Something I jokingly said at work, but dang if it isn't actually true:
"Everyone needs an emotional support R script."

You know, those R scripts in your project where you test your freak code before you're confident it works?

Data tables were different in 1870. This is the Dpt of Agriculture’s 1870 report.
Interior page from the Report of the Commissioner of Agriculture for 1870 showing a statistical table of agricultural products exported from the United States. The table lists categories such as animal matter, leather, wool, breadstuffs, cotton, wood products, ashes, and fruits, along with quantities and values in pounds, bushels, barrels, cords, and dollars. Page heading reads ‘Report of the Statistician,’ page number 63 visible in the top right Title page of the Report of the Commissioner of Agriculture for the Year 1870, published by the Government Printing Office in Washington, 1871. The page has centered black text on aged paper with some slight discoloration along the edges

I went into a store dedicated to woodworking. It was incredible even though I don’t do woodworking.

It's June, so it's baby deer season! Here is #fawn in the creek in my backyard.

Wild world outside my window. Cowbirds are brood parasites, i.e., they lay eggs only in other birds' nests. Here, an adult sparrow (left) accepted the strange egg in its nest and now raises the baby cowbird (right), who dwarfs its foster sparrow caregiver. #birds

Assuming your directory has a www folder with an image in it, then this works:
Screenshot of the Positron IDE. A quarto doc is open on the left side and the code creates three slides, with the first having an image background. The right side of the IDE shows the directory structure and that the background image is in a subdirectory named www. The code is the quarto file is as follows: --- title: "Image backgrounds" author: "Jeremy Allen" format: revealjs --- ## Hello {background-color="black" background-image="www/ai-office.png" background-size="cover" background-repeat="no-repeat" background-position="center"} ## oh look, slide 2 Neat! ## The End Bye :)

Believe it or not, Kieran is writing about #rstats here. There isn't a better community of users and developers.
This seems like what we wanted, doesn’t it? Superficially, yes. But what do I sacrifice? Calm. Kindness. Kinship. Love. I’ve given up all chance at inner peace. I’ve made my mind a sunless space. I share my dreams with ghosts. I wake up every day to an equation I wrote 15 years ago from which there’s only one conclusion: I’m damned for what I do. My anger, my ego, my unwillingness to yield, my eagerness to fight, they’ve set me on a path from which there is no escape. I yearned to be a savior against injustice without contemplating the cost and by the time I looked down there was no longer any ground beneath my feet. What is my sacrifice? I’m condemned to use the tools of my enemy to defeat them. I burn my decency for someone else’s future. I burn my life to make a sunrise that I know I’ll never see. And the ego that started this fight will never have a mirror or an audience or the light

The annual Fake Spring is here this weekend. I have to remind myself there will be more cold soon before real Spring arrives.
A peaceful backyard deck overlooking a wooded area with bare trees on a sunny winter day. A tripod-mounted camera facing the forest for birdwatching. A hanging bird feeder is visible near a tree, and a rustic outdoor chiminea sits on the deck. A tabby cat with white paws strolls across the wooden planks, adding a touch of life to the quiet scene.
