The guy diagonally in front on me on this @united flight just fired up Shawshank Redemption and I want to applaud his wise choice of airline entertainment.

Me and my husband argue all the time… about whether the cat is meowing because she wants food or attention.

@Ekaeoq Would this be a good light for doing puzzles? I want brightness but hate the glare of using a desk lamp.

@MemooRoberts @AuthorGFAllen Don’t be silly. You’re obviously going to be up all night finishing that masterpiece.

This new Harry Potter play has incredible stage effects!

@CDTEliot @Miles_Brundage Thank goodness it’s not only me. Can’t believe I didn’t know this.

Exactly. “You all weren’t “raised.” You were lightly monitored feral creatures with a bike and unresolved trauma.”

[Crazy Vibes @CrazyVibes_1]

Dear Gen X,
I’ve been watching 80s movies and I just need to know…WHERE WERE YOUR PARENTS??
Every child was just wandering the earth unsupervised like a raccoon with house keys. Riding bikes across town at midnight, fighting ghosts, investigating murders, befriending cryptids, hacking government computers for funsies…
And the parents were ALWAYS “out of town” or “working late” while the only adult-adjacent supervision was some random 16-year-old who got dragged into the chaos.

No cell phones. No helmets. No adult supervision. Just vibes, life lessons, and several near-death experiences.

You all weren’t “raised.” You were lightly monitored feral creatures with a bike and unresolved trauma.

I’m genuinely shocked there are enough of you left to populate an entire generation.

@jwt0625 What is a deep nontech gf vs a regular nontech gf?

@jwt0625 Memory access and transfers. Joules per byte moved to/from memory is still too high.

@jeremytrimble To be fair, that’s because I’m more of a lurker than a poster. Still recovering from Physics Usenet troll trauma; never regained the courage to write my own posts.

A classic.

Kinda love this cooking analogy for CPU vs GPU.

[Yagi @sa_vatsa]

The most interesting part the "data tax" and how systolic arrays in TPUs solve it.

Objective of a chip is to do maths but to do that it needs to have data to do the math on.

CPU/GPU works like a personal chef who has to walk to the pantry (registers - data stores), grab a tomato (data), walk back (muxes), chop it, then walk back to the pantry for an onion. Most of the chef's time is spent walking , not chopping.

TPU works like an assembly line (Systolic Array). One worker stays in one spot with their knife (the weight). The tomatoes (data) slide down a conveyor belt. The worker chops as they pass by and slides them to the next person. No one has to walk anywhere, so the "chopping" (math) happens at maximum speed.

By using this "assembly line" design, AI chips can perform quadratically more math while only increasing the "communication" (data movement) by a tiny, linear amount. This is the primary reason modern AI chips are so much faster than general-purpose computers.

@typesfast So do you have to feed your planes once or twice a day?
