I’ve been puzzled more Dems aren’t suing for defamation NOW. It may be hard to do much about all the blatant political lies, but those that cross into defamation?

A product marketer at Broadcom shows a slide with the bandwidth their new chips can handle; 3.2 terabits per portΒ Γ— 36,000 ports ganged together. That’s a lot.

A product marketer at Broadcom shows a slide with the bandwidth their new chips can handle; 3.2 terabits per portΒ Γ— 36,000 ports ganged together. That’s a lot.

Then the same product marketer shows that those 32,000Β Γ— 3.2-terabyte collections of switches (that all look like one switch, by the way) can interconnect too for a half million 800Gbps connections, or a million 400Gbps connections. Again: that is a lot.

I’m at @techfieldday.com’s AI Infrastructure Field Day … @broadcom.bsky.social presenting. In two slides, how they do data center–to-DC(-to-DC) networking for large-scale applications and services. Pretty impressive

Remember: The recipe for economic growth isn’t tax cuts for the rich. It’s investment in our people β€” in health care, infrastructure and education β€” to build a strong middle class.Β 

You don't grow the economy through trickle-down nonsense.
