It's perfectly safe, I assure you.

It feels like they release 1 or 2 "products" a week and then we never hear about them again.

You do get more sensitive to bad lifestyle habits in your 30s, but none of those are normal symptoms attributable to "aging" in your 30s. Really weird when people around this age act like they're just on death's doorstop.

I've had a reckoning with my caffeine metabolism recently. I fall asleep very easily, like head hits pillow and I'm zonked within a minute. But I often wake up at 3 or 4am and am unable to go back asleep.

What I've learned is that caffeine metabolism goes down with age and sleep gets lighter with age. Even if you can fall asleep easily, the residual caffeine in the middle of the night is enough to wake you out of light sleep. I made a tool to convince myself to cut back: http://jitterdone.com

I still think this is a weird framing overall, but yes I see your quoted line "a height map is" was applying to this article and not generally.

> A height map is representing voxel data without overhangs.

A height map can represent voxel data if the columns are integer heights, in the same way an integer can "represent" an infinite number of countable things. It's like saying the number 7 is "related" to a group of 7 ducks. The relationship is kind of meaningless.

But more importantly height maps can use also floating point heights in which case there's no reasonable mapping between the two. So your statement isn't generally true.

This is a vague statement. Are you suggesting each column can can have multiple layers of terrain, air, terrain? IIUC, the article disputes this:

> Such maps limit the terrain to “one height per position on the map” - Complex geometries such as buildings or trees are not possible to represent.

FWIW I'm working on a voxel sandcastle game. People usually seem particularly surprised by this style because they're so used to such games being rendered by height maps which don't allow tunnels or arches or overhangs.

It's pretty common. I would assume any faceless channel is all AI now. Like I saw these fitness videos and I thought the voice was a little too good for AI, especially a year ago. But apparently the TTS models are really good. https://youtube.com/@yellowdude_co

"it's smarter than me?"

You don't have to correct it dozens of times a day!? Really?

I don't think those count as "moderate to vigorous" exercise, at least for most of the time you're doing any of them.

Classic of course. The point being: don't make fun of people for not knowing something. In this thread we're making fun of learned helplessness.

It's kind of amusing that you're asking for acronyms you don't know not to be used and acronyms you do know to not be spelled out.

Is 30 years old very new? We're on a site for tech people. I would wager most are familiar with this term.

I don't disagree. It's just a weird way to describe them currently when they just announced massively increasing limits.

> Pretended I didn’t know a childhood friend when they said hi because I didn’t know how to act around people I used to know

In high school because people thought I was a snob or something because of my social awkwardness. I love talking to people but absolutely hate initiating conversations. I love looking people in the eye when they're talking and hate looking at people as a I pass, so I usually don't even know who is walking near me. It's kind of crippling (and this is after it's gotten much better over time).

Very impressive, simple, and reliable. I'm sure it will be picked up by image generation labs soon.

Nostalgia, not an answer: my proudest moment from high school was coding a very primitive raycasting "engine" in VB6 (that's what we had in our programming class). I had no idea what I was doing and I used some sort of layout object to draw vertical columns.

Totally. Stopping at a specific time is a good rule of thumb, but you can obviously compensate for one half life by just consuming twice as much at the start.

And the surprising thing too for me: how low the threshold is where it can impact your sleep.
