you made me check out the 'For you tab' (I had an account to read post) and unlike you my X seems like a nicer place than yours : 1-a post from Macron on Pavel 2-a picture of a dog 3-another post on Pavel by a weird account 4-future will be tab tab tab by Karpathy 5- a post by Yann LeCun 6- Elon ... :( 7- an animation of a Cockatoo 8- an infographic explaining that paradoxically the shape the shape of a light wave ca…

a 220 volt 20 amp circuit should be good for over 3500 watts constant load in North America. Why is it requiring two circuits?
IIRC USA is 110V, not 220V?
Water heater, heat pumps, stove, dryer, hot tub, etc are all 220.

I thought to myself this morning: "boy, that $15k pricetage is tempting." Then I thought to myself "how many times have I downloaded a github repo only to hand-replace cuda with mps, and then tried to figure out if there's a version of xformers that will work this week with my m3?" and then I thought "boy, that $25k is tempting." (15k: Radeon / 25k: Nvidia). For those wondering, 3200W power, in residential / low-end…

Most folks aren’t going to unplug their water heater to turn on their AI.

Once I accepted that my "For You" tab got much better.

While logged out (on desktop at least), all I see is the single linked post with no other content, no ads, no popups. The worst is a couple of sign in/up buttons on the right side and a banner on the bottom of the screen asking me to log in. It's actually pretty great.
I guess it must be great to be tracked by Elon Musk's minions in exchange for some entertainment.

Most US homes have at least one 220v split phase line for major appliances like stoves or AC.
So if you want to plug in a device like this "tinybox" at home, it's going to be a lot easier to find two separate 110v outlets on different circuits than to have a new 220v circuit added, or to unplug your stove every time you want to use it.

A 4090 draws 450W unless you unlock the power limit
Transient might be an issue. GN discuss transients of ~30/40% over the nominal 450w ( https://www.youtube.com/watch?v=j9vC9NBL8zo&t=616s ). And with a distributed training you can end-up with "synchronized" transients over all cards :(.
A quick point: transient surges are usually fine. Both cables and circuit breakers are designed to fail (trip or burn out) under sustained overloads. For example, a 16A Class C circuit breaker might take around an hour to trip with a constant 17A load, but a ~80A load would trip it ~instantly.
PS: Of course, everything is a matter of integration over time (heat dissipation in cables mostly).
