It's similar to any anti face detection art. Probably useless but cool.

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

Voxel Space (2017) 2 months ago

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.

Voxel Space (2017) 2 months ago

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.

Voxel Space (2017) 2 months ago

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 smarter than me?"

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

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).

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.

I've been struggling with poor sleep for months. The 3am wake ups (can't fall back asleep) are really bad.

I figured it couldn't be coffee because I fall asleep easily. But it turns out that lingering caffeine can let you fall asleep at bedtime and then come back to haunt you later when you move into lighter sleep.

I've been in denial about my caffeine consumption because I've gotten away with it until now.

I vibe coded a little caffeine metabolism tool to face reality. I wanted something with a simple half-life formula and drag and drop using common beverages.

What becomes clear very quickly is: my caffeine consumption needs to be way lower and earlier to fix my sleep issues.

I can see why it would affect startups not making a profit but why would it dramatically affect FAANG (e.g. some of the most profitable companies in the world that have been running for decades)? The article contributes all these large layoffs in FAANG, in part, to this tax rule.

Fair enough, but I don't think you realize how the original comment comes off. There's a lot of wiggle room in the terms "interested", "engineering", and "unremarkable", but the way I take it is: if one hasn't become a legend in their field by age 40, not only do they not deserve a job, they don't deserve to be here (since they're clearly not interested in engineering).

You're right on many of these points and I probably take it personally because I'm coming up on 20 years and am unremarkable. You never know what people went through to get where they are.

I went to a cheap state school, didn't major in CS despite wanting to desperately because my family convinced me it was a bad move, graduated into the GFC, got pigeonholed into QA for a while, spent years getting my masters in CS, wasted energy on side projects for many years, cared for sick family members for many years, struggled with major impostor syndrome and insecurity.

I've done things I'm proud of and I made it to FAANG after all that, but am unremarkable. It's kind of offensive to then hear that I'm not interested in engineering because I'm not a Distinguished Engineer or whatever.
