The energy at the Google Cloud Booth #513 was electric! We were thrilled to welcome @NVIDIA CEO Jensen Huang to the Google Cloud booth at #NVIDIAGTC. From discussing our integrated AI stack to the future of agentic AI, the partnership has never been stronger. He even left a little note to Thomas Kurian on our booth wall + signed a Google Cloud A4X Max powered by NVIDIA GB300 NVL72 and the NVIDIA Vera Rubin NVL72. ✍️

Excited to share that our new A4X VMs - powered by NVIDIA Blackwell GB200 - are now in preview. We are the first and only cloud provider to offer both GB200- and B200-based systems today. https://t.co/zRxeEjkTA0

We’ve been working closely with @nvidia to sustainably build compute infrastructure of the future. Check out a sneak peek of our custom GB200 NVL racks running in our labs.

Protip: Di2 cables can be cut and joined in any combination. Red to red, black to black. Ditch Junc B, hide cabling or move parts out of sight.

Pic: a handlebar splice to use sprint shifters with the internal Junc A, otherwise impossible due to the lack of e-tube ports.

@petejohanson @ZMKFirmware Dactyls generally need very high wrist rests or a very low desk. The Chocs reduce the height by about 10mm. Much easier to fit into a regular work environment.

Dactyl Manuform (modded), fully wireless thanks to @ZMKFirmware .

It's really easy to cut cable locks. I lost my key but have these $10 wire cutters for big power cables. Less than 15 seconds of effort.

An XT90 'antispark' connector after about a dozen insertions. At high voltages it's easy to burn out the antispark resistor, and after that, the contacts.

Sabvoton 60A controller vs. Baserunner 40A controller. 50% more power, but 10x weight and volume.

@skcotterell @ID_AA_Carmack So long as the skin temperature stays under 43C, you're good up to 8 hours. Cooling effect is meaningful for devices without fans.

Only in the Bay Area.

Prediction: There won't be high-performance M1 chips for high-end Macs. Instead, they'll scale M1 horizontally using PCIe as interconnect.

(Mac is too small a market for Apple to produce multiple chip versions, and a 1x/2x/4x config fits their existing product line oddly well.)

That's not a case. That's a mic calibration rig.

3/3 Apple M1 is a great chip, but "2020 Intel MacBook with a working cooling fan" would easily trounce all prior MacBooks.

[Ian Howson @ianphowson]

2/3 e.g. MBPro 13" 2020 ships a 4GHz CPU, but chassis thermals limit it to 1.4GHz steady-state.

MBAir has a fan which is not even connected to the CPU heatsink.

MBPro 16" somehow burns 30W if you plug it into the wall.

[Ian Howson @ianphowson]

1/3 Every Intel MacBook since 2016 has utterly broken thermals. The M1 had bloody well better be faster; the comparisons are against machines that are severely throttled in normal operation.

[Ian Howson @ianphowson]

Can confirm

Someone has made a map of Australian states with their US equivalent and it's pretty spot on tbh
