Daisy, a large white dog, lying on the floor, slight out of focus in the background of the picture. In focus is a breakfast croissant sandwich and a small bowl of fruit. Reader, the dog was partaking. Evidently, not sufficiently so

A screenshot of line of code typeset in some monospaced font. The word "flush" is typeset criminally poorly because of a baffling ligature. This is a sin.

Claude prompt: I want you to help me turn of every single notification LinkedIn shows in their preference pages. I've signed in to linkedin in Google Chrome under a tab that you should have control over in your devtools plugin. Can you take it from there? Starting from "Posting and Commenting", I think everything is still on. If you can turn off all automated email messages too, that would be even better.

Screenshot of a tiktok vídeo of a warmup for a soccer game at Alfredo Jaconi, up in the hills of Rio Grande do Sul. You can't see much, but neither can the players; that's the vibe

Good. Now let me continue with the enemy module. write ... Validation failed for tool "write": - path: must have required properties path, content Received arguments: {} I keep making the same mistake. Let me think about why this is happening. I'm calling write without providing the path and content arguments. I need to provide both. I apologize for the repeated errors. Let me continue writing the remaining files: write ... Validation failed for tool "write": - path: must have required properties path, content Received arguments: {} I'm still not providing the arguments. Let me be more careful this time.

A GitHub banner today, reading "Some pull requests may be missing due to an ongoing search incident, but no data is lost. Use the API or GitHub CLI (gh pr list) for complete pull request results. "
The word `render` typeset with whatever default typeface Zed uses. On small type this looks like a dotless i, it's horrible.
A picture of a macOS Tahoe setup Screen. Its literally the first Apple logo to be visible on a new MacBook Pro setup. It’s misaligned. This is embarrassing

Slay the Spire 2 screenshot right before killing the last boss (Queen) in ascension 3. Playing the silent. 61/61 HP, 135 block left over. Not on screen, a Murder worth about 200 damage at this point.

Contents: they scheduled a meeting with me to connect. the meeting was on ms teams. the meeting had what seemed to be a group of people that were involved. the meeting said something on my system was out of date. i installed the missing item as i presumed it was something to do with teams, and this was the RAT.

I don't think I can write the LaTeX for this in 2k characters. It's the definition from https://en.wikipedia.org/wiki/Meijer_G-function
The D4 wavelet basis function. It’s a recursive construction that somehow ends up being asymmetric, full of little spikes where you don’t expect them. It looks like it would cut you up
Me: I had a good internal laugh when I realized this is what was going on, and there’s not a lot of people who’ll get it, but you will it’s literally that “first meeting with a grad student where you context dump on them” Except this thing doesn’t roll its eyes Them: This reminds me that I sort of want to “hold court” in a long rambling speech (not typed) as input to an instance of CC, which I ask to clean up, and then use that as the initial input to CC. When I’m talking, I rarely get fatigued (no jokes, please), but when I’m typing, I often run out of gas. Me: You’re not the first person to describe that to me - I know (online) someone who starts their day by taking a long walk with the apple voice notes app, then has a pipeline for transcribing that into a model that cleans that up into a CC session
Tyler Cowen is the only loser in the world whod write he liked Tilly Norwood. I’m not transcribing the actual text of the piece, I refuse to participate in his perversion. It’s from the free press. It’s fucked up loser shit, and you know it
Snippet from Claude Code session with Opus 4.6: ⏺ There it is. The smoking gun: main=false, #qdc=false, article=false, body=false main is null/undefined, returning empty string clone.body is falsy on a cloned deno-dom Document. The cloneNode(true) doesn't preserve the .body convenience getter. This only matters for page-layout: custom pages because they lack <main> and #quarto-document-content elements that normal pages have. Let me verify that clone.querySelector("body") works as a fix.
