well, i measured that on windows (since I still run windows on my main PC) but I assumed it would be similar on linux lol

steam is like 500 MB of ram by itself at least for me rn, so add any game or os stuff on top and it rounds up to a gigabyte

Windows file manager opens things in apps based on file extensions, and then it’s up to the apps to figure out what to do with it. I did a bit of testing, and it seems like Firefox is fine with opening JPEGs mislabeled as PNGs, but not PDFs mislabeled as PNGs. LibreOffice Draw is fine with that though, so if in windows I set that as my default for PNG files, it opens a PDF labelled as a PNG perfectly normally (and can also open actual PNGs normally).

If I just completely delete the extension from a PNG or PDF, Firefox will open either correctly.

obviously tests aren’t everything and don’t necessarily reflect user experience, and idk what that jump in safari at the end is from, but chrome clearly has some things going for it.

currently chrome passes 97.4% of applicable tests, firefox passes 95.8%, safari 94.8%, ladybird 92.9%, and servo 89.6% (a lot of the bulk is “easy” stuff like text encoding)

Reminded of how, for some unfathomable reason, the way you access the task manager on ChromeOS is through the hamburger menu in the bar of the Chrome browser. Plus the popups “gmail actually works much better in chrome!! trust me!!”

I can see how people could get confused lol

It’s funny how that question can become serious again when you do actually know what you’re talking about

I remember this video addressing it at the end and basically giving up because it’s so meaningless lol https://www.youtube.com/watch?v=ZmPIxfCggFw

There’s the people who know what source code is, then the subset of those who have heard of open source, then the subset of those who actually know what it means as opposed to like source available

I first got introduced to Blender in basically the same way back in elementary school

those computers probably weren’t actually very restricted, but none of us knew enough about computers for that to matter lol. as long as they blocked us from going on the download pages

other stupid thing someone figured out how to run was that Star Wars ASCII thing in the terminal (lol looked it up and found this article https://www.instructables.com/How-to-get-an-ASCII-Star-Wars-movie-on-Mac/)

Conflicted on filename extensions. For the average person it works just fine, and I suppose that’s what probably matters. It’s not very common for not knowing the details of how they work to matter. It’s just silly that the same information is also in the start of the file 99% of the time. It is nice though to have a readable, usually reliable label, and then have a signature anyways for when different names overlap. Wikipeda lists 4 completely unrelated types with a .mod extension, for example.

Pretty much any application will correctly open any file type it supports, regardless of the extension. So it is quite unintuitive that you could have a file named “.png” that seems to work completely fine yet is actually a jpeg or something. But that hopefully isn’t a case that people run into very often, so it probably doesn’t matter.

maybe orcaslicer for 3d printing people? seems like the most popular nowadays, although it’s getting so fragmented with every manufacturer’s own slicer branch…

yeah, this is hard

oh, people who do streaming or youtubing stuff probably know OBS

there’s also probably a certain demographic for audacity

you could have a camera host a local web server lol

… i guess i’ve kinda done that in first robotics (although that was a live feed)

Can get a used quest 2 for like $100, not crazy but not nothing. Unfortunately not powerful enough to view the more detailed rooms or avatars, or so I’ve heard.

It’s good to encourage reuse, which is eBay’s main thing. I wouldn’t have a reason to buy anything new from them however.

I got my home server (Lenovo thinkcentre, i7 6700) for $30 minus ram or storage at my local university surplus store a few years ago, and I have no regrets. Added a 256gb sata SSD, 16 gb RAM, 8tb HDD all refurbished for like +$150 when that was still cheap.

That one was, but the current one is not

If you are playing games where trackpads are useful, there’s not really another option, so it’s automatically a good value. I know my steam deck experience would have been a whole lot worse without those, and I would probably never consider a gaming handheld without them. But for the gaming I do with an xbox controller, I currently just use it for some video games at my computer (where I have access to a mouse anyways), and maybe split screen with family. I think my Gamesir Cyclone 2 controller (at half the price) is an unambiguously better deal for that, in the premium controller space. If I were using it mostly for couch gaming, that might put the Steam controller in a better position, or if I were mostly playing games that support whatever haptic trigger things Sony has, that controller might be in a better position.

One of the other more unique features is the tracking in the Steam Frame. It would be cool if they could standardize that sort of thing so it would work with other headsets. I wonder if they’ve considered that.

They can make it illegal to sell certain types of hardware to consumers that allows you to install your own operating system. Of course, there is still virtualization. You can run Linux in a web browser nowadays (badly, but if there was a reason to improve it I’m sure it would be done)

As an amateur computer graphics person, the best way to draw accurate stars is to just pre render it onto a cubemap. But if you really need that subpixel worth of parallax to be completely accurate for every star, there are a couple ways I can think of off of the top of my head. With any you’d want to make sure you only store position, size, and color, since stars are all spheres anyways. With effort, you can be very flexible with how these are stored. (4 bits color temperature, 4 bits size, 3*32 bits coordinates maybe)

• splat each star into the screen texture with atomics
• some sort of tiled software rasterization thing, like in Gaussian Splatting

Worse ideas:

• instanced hardware rasterization
• ray tracing

This is not that well suited to most usual rendering techniques, because most stars are probably going to be much smaller than a pixel. Ray tracing would mean you need to just hit every star by chance (or artificially increase star size and then deal with having tons of transparency), hardware rasterization is basically the same and additionally is inefficient with small triangles. I guess you could just live with only hitting stars by chance and throw TAA at it, there’s enough stars that it doesn’t matter if you miss some. That would react badly to parallax though and defeats the purpose of rendering every star in the first place.

It’s much more efficient to do a manual splatting thing, where for each star you look at what pixel(s) it will be in. You can also group stars together to cull out of view stars more efficiently. Subpixel occlusion will be wrong, but it probably doesn’t matter.

This is all just for the viewport, though. Presumably there are other objects in the game besides stars, which need to have reflections on them of the stars. Then that becomes an entirely different problem.

The real answer though is that you wouldn’t try to render all of the stars, even if you want parallax. Maybe some of the closer and larger ones as actual geometry, simplify a ton of stuff in the background, render things as volumes or 2d billboards, have a cubemap for the far distance, etc

Edit: also ofc this presumes you know the position, scale, temperature of every star

I also like the idea of baking all of the stars into a volume in spherical coordinates, centered around the origin

It’s clear that several people in charge of the youtube livestream have no idea about how to do that correctly. I think the difference is just effort. Viewership was tiny compared to Apollo 11, as was the hype leading up to it. It’s clear that NASA could provide a whole lot better footage if even some random youtuber (Everyday Astronaut) can beat them. So that aspect is, as you said, because as a society we don’t really care about the Artemis launch. SpaceX does put a fair amount of effort into their livestreams, and you can easily tell by watching them.

For the recorded footage, film often has a lot higher dynamic range than digital cameras and usually looks a whole lot better when recording a launch up close.

Far shots are limited by atmospheric distortion and physical limits from diffraction for a given aperture size. None of that can change.

IDK anything about the quality of the original live broadcast of Apollo 11, so i don’t have anything to compare in that regard

Yeah, I rewatched the launch from Everyday Astronaut’s livestream and he actually had better footage, he had a tracking camera showing the booster separation

Outside of the launch part, I think it’s mostly because SpaceX has set the standard so high, with tons of high resolution cameras streaming over Starlink even during reentry
