EarthLaunch··on Ancient Rome's failed building projects
Physical work can be fun too!

Neither as much when you're a slave of course.

EarthLaunch··on Brave Leo now uses Mixtral 8x7B as default
I've been using it for 'easy' queries like syntax/parameter questions, in place of ChatGPT 4. It's great for that. I am using a ~48GB version.
EarthLaunch··on How much memory bandwidth do large Amazon instances offer?
For the curious like me, here's the script running on consumer gaming Intel hardware (i9 14900K, 2x 48GB DDR5 6600MHz CL32 XMP, Windows 11):

  1 27.6
  2 50.5
  3 62.5
  4 68.3
  5 75.6
  6 82.6
  7 87.4
  8 90.7
  9 93.0
  10 94.3
  ...repeating
I expected a bit more, my guess would have been around 120 GB/s. I've been playing with LLMs and this hardware is about as fast as memory gets on consumer Intel without overclocking.

EarthLaunch··on Stellarium: Software which renders realistic skies in real time
The map is based on GIS data of Colorado :) Including terrain elevations, landcover, and water.
EarthLaunch··on Stellarium: Software which renders realistic skies in real time
Here's an original PNG exported from Stellarium. For the game this had to be reduced and compressed a lot: https://i.imgur.com/v3g219F.png

Screenshot of how it looks in-game, this is Stellarium-generated and shown as a KTX texture on a 6-sided skybox: https://i.imgur.com/bkW2CXX.png

EarthLaunch··on Stellarium: Software which renders realistic skies in real time
Thank you. Right now it's a just explorable small section of Colorado. The premise is a post-earth world where players build up villages around trade, inspired by Ultima Online.
EarthLaunch··on Stellarium: Software which renders realistic skies in real time
I used Stellarium to generate the realistic (but somewhat over exaggerated clarity) skies for my web game. The day/night cycle only shows stars at :50-00 of each hour: earth.suncapped.com.

I'll edit into this comment a link to the texture files if I can, but the game uses compressed (ktx I think) textures since the star textures are large resolution, one of the largest game assets!

I picked a particular date, time, and place on earth for rendering the sky in Stellarium. It also had options for seeing (clarity) and which features to show, such as planets or space debris.

EarthLaunch··on How Gyms Make Money (2015)
I think it's because the scammy techniques allow lower apparent princes. People who shop by price will end up at the scammy gym. Maybe people are sensitive to price when it comes to gyms, and/or the true cost of a gym membership is too high for almost anyone.

People who don't want to admit the cost is too high are perfect targets because they also don't want to admit they will want to cancel in the future. I, uh, am talking about a friend of mine, of course.

EarthLaunch··on Human sperm cooperate on the competitive pathway to fertilization: study
> It's like if *humans* went around making all of the important decisions and only bothered to spin up a *machine* briefly for reproductive purposes. But then the sex *bot* got a bit out of control and got a job and an apartment and now it's the humans who look like they're just for reproduction.

This perspective could kind of also apply to plants, a la The Botany of Desire (good book). From a certain plant's perspective, humans exist to help them reproduce.

EarthLaunch··on Procrastination is connected to perfectionism
Thanks for mentioning this in a work context. It describes one of my parents, with the results you'd expect.

Do you remember any of the thoughts or techniques you used to shake it?

EarthLaunch··on Visualizing expert firing frequencies in Mixtral MoE
I did this with 24GB VRAM and 32GB DDR5, using LM Studio, and it was about as fast as I could read. (I read fast but I'd have to run it again to guess the token rate.)

I'm upgrading to 96GB RAM now to run the larger models, but I do wonder whether it'll be slow when using proportionally less VRAM.

EarthLaunch··on Nvidia CEO: We bet the farm on AI and no one knew it
The article mentions this choice being made in 2018. I don't know the ML industry, but as a gamedev I had been mystified about Nvidia's strategy since about 2018.

It felt like they weren't leaning into crypto, which surprised me. Instead it looked like they were trying to maintain gamer goodwill by not increasing consumer card costs during the boom. Of course scarcity raised secondary market princes, but Nvidia kept MSRP lower than the boom dictated.

It seemed like they were betting against crypto during the craze. And sticking to their strategy on the consumer side. So maybe that's how they stuck to a ML strategy too.

So they had all this CUDA stuff, which they must have invested in heavily because AMD showed what happens when you don't. That led to a software ecosystem for ML.

Maybe it was all luck, but a strategic choice explains some of this in hindsight.

EarthLaunch··on AMD's CDNA 3 Compute Architecture
I first recall it from the rise of AWS at least. "Amazon Elastic Compute Cloud (EC2)" launched 2006 [0]. Google Trends [1].

EarthLaunch··on X.com is Twitter, but what are [a-z].com?
I'm just disappointed that people go along with takeovers of useful words: x, meta, alphabet. If one was renamed "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" would people still go along with it? What's the limit?
EarthLaunch··on Google calls Drive data loss "fixed," locks forum threads saying otherwise
With those figures, that would be 1000 objects per year.
EarthLaunch··on Gemini AI
And it's not judgmental. It will recommend a better way of doing things, but especially when you explain why you're doing a certain thing, it will help with actually doing it.
EarthLaunch··on Cognitive ability and miscalibrated financial expectations
The demons that apparently haunt you in academic papers are created by yourself with such a comment.
EarthLaunch··on Cognitive ability and miscalibrated financial expectations
> But [pessimism] promotes inaction.

I don't know if there's evidence, but I find the point interesting because the idea occurred to me independently when I read this in the paper:

> Unrealistically optimistic financial expectations [...] can lead to excessive business entries and subsequent failures, as optimists overestimate the financial returns from entrepreneurship (de Meza et al., 2019)

I thought: Do pessimists overestimate the financial returns from a regular job?

It seems in many ways to be about whether/what risks are worth taking.

EarthLaunch··on Reel Inequality: Charting the Vanishing Middle Class of Movies
And Torth series. No punches pulled on the logical outcomes of superintelligence and powers.
EarthLaunch··on Switching to Elixir
Maybe it depends on what you're prototyping. In web dev I see what you mean.

But in game dev I'm often prototyping something to see if it works at all, or to check its performance. Ignoring types is faster when spending 1-2 hours/days quickly hammering out something that just barely works. On version 2 or 3, add typings.

Maybe it also depends on the timeframe of the prototyping project. After a few days it can become tech debt. (Though I still suspect there are some long term advantages to untyped.)

EarthLaunch··on More Than 80 Percent of Americans Can't Afford New Cars
The prices don't match the value except as a luxury item. Maybe that was a switch to make cars more profitable?

I see little appeal in a new car. Huge money sink, long waiting lists, sketchy dealers, sketchy warranties, software-based without being run by software companies, and all for what? To be able to travel in an unpleasant, dangerous road system.

Buying these feels more like an obligation to avoid, not something fun and worthwhile. Like checking the mail for bills.

EarthLaunch··on Gene-Engineered Mouth Bacteria
> I have yet to find interdental toothbrushes whose use doesn't lead to ingesting nylon.

Isn't that all toothbrushes, or are interdentals unique? (I haven't used them.)

I always assumed that toothbrushes would shed microplastics during brushing.

Also, avoid flossers, as they usually have PFAS. I use a water flosser instead.

EarthLaunch··on Terraria developer bashes Unity, donates $200k to open source alternatives
It is such a better developer experience. My unfinished Three.js game[0] was on Unity a few years ago, but that became unbearable. The modern web platform is too new, it hasn't proven itself to big money, so it's going to be indie games first.

To answer sibling comments: Graphics aren't a limiting factor for indie games. And a Three.js game can be put onto Steam, I'm pretty sure.

EarthLaunch··on Peredvizhnikov Engine: Lock-free game engine written in C++20
It's a requirement for any game that needs a reliable frame rate. Unpredictable delays during frame rendering cause jank.

(This is not to say the OP has any such issues in its context.)

EarthLaunch··on We’re all just temporarily abled
> Through all of it, I’ve found myself noticing “accessibility” helpers more than ever before: that railing on the stairs, that ramp off to the side of the building, that elevator tucked away in the back.

The title got me because I was fortunate to have this revelation too. I'd sprained a foot joint jumping off a small staircase. A day later I could barely limp into a med supply place to buy crutches. My "outdoors" vacation changed completely.

Suddenly I'm worried about people judging me, and I'm intensely grateful for ramps, I care about parking spots, and it dawned on me that I'd ignored all this infrastructure that I now needed.

Thanks.

EarthLaunch··on 2009scape
I'm making a UO inspired MMO and have been wanting to play more MMOs lately. Anyone similar up for experimenting with RS, WoW HC, Zenith, LiF, MO, UO player servers, or anything? Hit me up!
EarthLaunch··on How should I read type system notation?
I try to do this at home [eg 0] and it flabbergasted some coworkers when one such notation accidentally slipped into a day job PR last year. I didn't try to argue for it- but I like it personally, mainly for making control flow easier to skim.

EarthLaunch··on Is Venus in some way tidally locked to Earth? (2020)
> Please don't post comments saying that HN is turning into Reddit. It's a semi-noob illusion, as old as the hills.

EarthLaunch··on Cargo Cult Science (1974) [pdf]
People aren't saying nice things about Apple to appease Apple from locking things down.

People who rebelliously use non-Apple products are helping to keep the alternatives alive. It's a tradeoff of now vs future. That's the real tradeoff, it's not cults.

(edits: HN vs who?)

EarthLaunch··on Try the last internet Kermit server
This is actually kind of genius:

> To reduce transmission overhead, the Kermit protocol uses a simple, but often surprisingly effective, compression technique: repeated byte values are represented by a count+byte combination.

> Analysis of large volumes of both textual and binary data shows an average compression of 15-20%.
