Nvidia says two mystery customers accounted for 39% of Q2 revenue

Nearly 40% of Nvidia’s second quarter revenue came from just two customers, according to a filing with the Securities and Exchange Commission. On Wednesday, the chipmaker reported record revenue of $46.7 billion during the quarter that ended on July 27 — a 56% year-over-year increase largely driven by the AI data center boom.

'Ten Martini' Proof Uses Number Theory to Explain Quantum Fractals

But in some ways, the proof was a bit unsatisfying. Jitomirskaya and Avila had used a method that only applied to certain irrational values of alpha. By combining it with an intermediate proof that came before it, they could say the problem was solved. But this combined proof wasn’t elegant. It was a patchwork quilt, each square stitched out of distinct arguments. Moreover, the proofs only settled the conjecture as it was originally stated, which involved making simplifying assumptions about th

Local Restaurant Exhausted as Google AI Keeps Telling Customers About Daily Specials That Don't Exist

If you're trying to find out what a restaurant has to offer, you might look up its menu, or go to its Facebook page. Hell, you could call and ask. But that's all démodé. Why not query an AI chatbot, a piece of software notorious for inventing facts out of the tokenized ether of the internet, and treat its answer like the word of God? Here's why: because you'd annoy the hell out of the restaurant. Just ask the beleaguered owners of the Montana eatery Stefanina's Wentzville, who are begging thei

The days of custom Android ROMs are numbered, and Google is to blame

CalyxOS, a major privacy-focused Android distribution, announced a sudden freeze on future releases earlier this month. While the project isn’t di
