Man I fell for it until I saw your post. In fact, I was just about to post what the man's name means in Italian. I was even going to point out how ironic it is that the mans first name and last name fit together so well. In my defense

I guess it'd only work in places where the locals don't use AC. Otherwise it'd be a killer to run in the summer, and so you'd have capital goods rotting in a persons basement half the year. If the user has AC for the sum

"now run that unshielded wire 50 meters past racks of GPUs and enjoy your EMI" Multipole expansion scales faster than r^2. Also, im not in the field (clearly) but GPUs cant handle 2.4 kHz? The quarter wavelength is 30km. "not

At 100 000 A for a 100 MW data center at 1000 V, speaker wire is a joke. You obviously need at least a dozen stands in parallel!! Clearly skin effect scales with frequency but, 400 Hz is still low, only 2.5x lines frequency (the scale is by

How is DC better than a three phase delta 800Vrms, at 400Hz? - Three conductors vs two, but they can be the next gauge up since the current flows on three conductors - no significant skin effect at 400Hz -> use speaker wire, lol. - large

So what Iran did in the Gulf Cheap drones overwhelming defenses until the billion dollar radars and airfields got hit. Then methodically hit everything according to a plan that forces allied forces to retreat to reliable water sources. Wha

But they can steer, videos show that. This really shouldn't surprise anyone. Iran graduates as many engineers as the US (70% women), but few of them are working on front-end A/B optimization of some boutique dating site. And, havi

To be fair, a golf ball's trajectory is hardly ballistic given its relatively large surface to volume ratio. Never-mind the dimples are there to cause a turbulent boundary layer to lower drag.

No? Today's your lucky day, you get to learn about the Mpemba effect. (Although the why of the effect is disputed, the trivial counter to your point is that boiling water loses mass quickly so there's less mass to cool)

A full model of a cup of water cooling is, in fact, incredibly difficult. Impossible, since it is chaotic. But a T(t) model should not be too hard for an LLM with a basic heat transfer book in its training set.

The problem is both highly complex, but fairly easy to model. Engineers have been doing this for over a century. Of all the cooling modes identified by the author, one will dominate. And it is almost certainly going to have an exponential r

Racist? That's new. Because he's conservative? In the 90s he sued one of his franchisees for defamation of character because they were racist.

I worked for a startup once for a brief time. Engineering would make tools for the sales guys to make websites. We hated those bastards because they would litter the pates with adds. "We need revenue" they'd protest. Engineer

Which is why I stressed that successful WFH is one of many enablers of off-shoring.

I dunno, I'm just an amateur photographer. The calculation isn't too hard though. The width of a pixel divided by the velocity of the subject on the sensor is the maximum delta(T) between real and ghost frames. But, again, you don

Sorry, I'm a bit of a noob on llm. What is "prefill"? As opposed to what?

Two problems: - It'll bleed on fast motion. Hair in the wind would just not work. - Incandescent lights are out. You could solve both by having two ghost frames shot very close to the real frame (no need to evenly space the frames, aft

Why didn't Professor tang just put the wok back on the stove for a few seconds. That'll dry out it out fast and you can see the film disappear. Under careful supervision, the wok won't even get anywhere near 100C

If you can WFH you've demonstrated to your employer that one impediment to offshoring your job is gone. Thats not to say there aren't other impediments. Maybe your job is legally protected onshore (military) Nor is this a value ju
