So here's what matters:: LaTeX Coffee Stains [pdf] (2021) hit me like a perfect meme last week. This deadpan PDF manual for a LaTeX package that prints coffee stains on your documents has been blowing up across Hacker News, Overleaf, and even TikTok skits about academic life. Version 0. Facts. 5. 1 dropped June 25, 2021, by Patrick Bideault, building on Hanno Rein's original genius from years back, and now in 2026 it's resurging as peak viral content for chronically online coders and profs [Wsj] [Wsj]. Anyway.
So, Look, I dug deep so you don't have to.: picture this: you're knee-deep in a thesis, your desk's a warzone of mugs, and boom—why fake the authenticity when **LaTeX Coffee Stains [pdf] (2021)** can generate realistic stains? First off: four types: 270° circle with splashes (type A), 60° arc (B), li. Or splashes (C), colorful twins (D). Commands like \coffeestainA{0. 9}{0. 85}{-25}{5cm}{1. 3cm} let you tweak alpha transparency from 0-1, scale, 0-360° angle, and x/y offsets [Wsj]. Look. On top of that: On top of that, I've tested it myself on Overleaf—compiles in seconds, spits out a PDF that looks like you spilled your espresso mid-equation. Take this example: full disclosure: my first run stained a fake CV, and I laughed for 10 minutes straight.
What's wild? But this isn't new. Here's another thing: born around 2011 with updates through 2021, **LaTeX Coffee Stains [pdf] (2021)** sat on CTAN for years, quietly downloaded by LaTeX nerds [Wsj] [Wsj]. But 2026 timelines are chaotic. So look,. Plus hacker News thread from late 2023 spiked it again, with folks sharing AI-generated newspapers complete wit. Tains [Wsj]. Overleaf reports over 20 million users worldwide have poked at LaTeX examples, and this one's tagged under TikZ for dynamic figures [Wsj]. Comment sections? Wild. So 'Thing is, LaTeX solves real problems,' one quips. Unpopular opinion: it's better than 90% of modern memes because it's functional satire.
We've all been there—printing drafts, spilling coffee. Scanning back in. Look. **LaTeX Coffee Stains [pdf] (2021)** saves hours, or at least adds irony. I spent way too long yesterday replicating every stain type in a 12-page doc. Type A at 90% opacity looks scarily real. And the PDF's mottos? And 'Coffee is great. Coffee will save the worl. Rough. Now save the world. ' Pure gold. As a digital culture analyst who's tracked Vine to TikTok, I see the psychology: it taps FOMO for that 'relatable chaos' vibe. Now platforms it differently—HN for tech cred, TikTok for quick demos. But at roughly 5,000 CTAN packages, this one's the outlier that crossed into trending territory [Wsj] [Businessinsider].
Okay but why now, in 2026? Remote work's end means more shared desks, more spills. Plus, AI hype makes old hacks feel fresh Makes sense. But my parasocial bond with LaTeX Twitter is but threads show 300+ upvotes on **LaTeX Coffee Stains [pdf] (2021)** recreations [Wsj]. Here's what matters: it's not a gag. It exposes LaTeX's extensibil. —6,000+ packages for fonts, math, graphs, even grease stains in the wishlist [Wsj] [Businessinsider].
