Testing limits in a software environment or hardware architecture by discovering if it is possible to play Doom on it has always delighted. However I do wonder what an outside viewer would think about our fascination with killing demons in low-resolution on anything that shifts a binary digit.

I'm feeling attacked by @theonion.com but also 10/10.
"How a Book Becomes A Bestseller, The Onion demystifies the publishing process."

1. Proletariat becomes literate. 
2. Author's creative inspiration flourishes upon marrying spouse with high-earning, unethical job.
3. Author chooses magical being to have sex with, then works backwards.
4. Author lands agent by running full speed into them while holding loose-leaf copy of manuscript.
5. Penguin Random House blackmailed into seven-figure book deal.
6. Editor removes typos and originality.
7. Famous author who hasn't read book reminded they got three glowing blurbs last year from authors who hadn't read theirs.
8. Publisher contacts Merriam-Webster to license all words it's using.
9. Marketing completely misrepresents plot, tone, and author.
10. Terrified independent bookstore owners gamble their razor-thin profit margin on this one.
11. PR firm hires thousands of people through Craigslist to performatively read book on subway.
12. Colman Domingo, contractually obligated to appear in all things, voices audiobook.
13. New York Times oracle nods.
14. Book written for sole purpose of becoming movie becomes movie.

Close to my heart, it is World Space Week, this week. Last night in the UK we had clear skies and I personally sat up till the wee hours and imaged the M33 Galaxy (Triangulum) en.wikipedia.org/wiki/Triangu... www.un.org/en/observanc...
A face-on spiral galaxy with a bright yellowish core and faint blue star-forming arms, set against a dense field of distant stars on a dark background.

Don't worry about how many tokens you are using, the AIs themselves are far outstripping your usage. Agents consume 7x as many tokens as users, I didn't realise that they enjoyed cat's-playing-instrument videos. Tell Morpheus I know who burned away the sky: www.tomshardware.com/tech-industr...
tomshardware.com
AI agents use 5x more tokens than humans as cached prompts explode, headed for 10x — agents are mostly rereading what they've already seen, skyrocketing KV cache demand threatens already-worsening RAM shortages
OpenRouter has agents at 7.3 trillion tokens versus 1.4 trillion for humans.
