> 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.


In the present case (Comanche) they clearly do represent integer heights.

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.

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.

The study specifically includes walking in their list of exercises. You probably do want a mix of exercises -- 90 minutes of vigorous exercise a week is a standard recommendation, but 10h a week of vigorous exercise is probably contraindicated for the average 57 year old in the study.

Walking is good exercise for anybody who is out of shape.


Walking as moderate exercise is not "just walking" though. You need sustained speed

Consider the speed/vigor with which one does something, whatever it might be. It can be quite the range.

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.


Its article is 5 years old… So, yeah, it’s new.


Its article was reorganized (moved from plain Capture the Flag to Capture the flag (cybersecurity)) 5 years ago. It's been on Wikipedia since 2004 https://en.wikipedia.org/w/index.php?title=Capture_the_flag&...


Nice catch, I didn't read that part.


Most people on this site are also familiar with the “XKCD 10000”.

But not all, so: https://xkcd.com/1053/

(Amusingly, it even uses “30 years” as the timeframe.)


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.


You are making fun of people who are saying that this article is shit, without addressing that part at all.


consider 2 conversations

"hey what X means?" "X means it"

vs

"I dont know what CTF stands for so I dont know if I am interested in this article or learning anything about it. Maybe I am.

Are you really arguing for not just typing out whatever 3 words this stands for once in the name of clarity?"

The commenter could just say the first instead of deciding his learned helplessness is everyone's else problem


The commenter above replied to me, who checked what it is, which is clearly stated in my comment. So your comment cannot be applied to the guy who came up the first with "learned helplessness" in this thread, who replied to me. That guy clearly just wanted to shift the topic from that the article is shit, because they cannot do anything with it.

Also yes, search for CTF is not simple regarding security, because first you need to know that you are searching something in the topic of security. Because every other usage of this is way more frequent. Especially that there is an other way more frequent computer related usage. And the article doesn't make this clear in its first 173 words for laymen. Even I had a problem with this, who is not at all layman, just never cared about this part of security. It's a bad article.


More acronyms?? What the heck is an XKCD??? ;)


You mean the company that just doubled their rate limits? https://www.anthropic.com/news/higher-limits-spacex


They only did that after they "found" ~300k H100 equivalent compute. Before signing that deal they were severely compute constrained. Especially visible when EU tz was still active and US east would wake up.


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


Anthropic hasn't solved their compute constraint issue. Colossus just makes it a little easier.


> 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.
