emscripten VS Proton

Browsers limit the ability for these platforms to use raw sockets, there simply is no API for it. The best that can be done /today/ is to use WebSockets, which are not the same thing any can't be used for HTTP requests without the server expecting a WebSocket connection:

Only half true. Emscripten implements the SDL 1.2 (and also SDL_mixer 1.2) API in Javascript here: https://github.com/emscripten-core/emscripten/blob/main/src/.... On the other hand SDL 2 (and SDL_mixer 2) are proper ports (which you linked to).

So there's quite a size penalty to using SDL 2 rather than SDL 1.2.

Playing with low-level stuff is fun, but I won't use it anywhere in productionable code. Well, at least without considerable experience and understanding of the Emscripten code base.

Thank you for your comment!

WASM gave Figma a lot of speed by default for a lot of perf-sensitive code like rendering, layouts, applying styles and materializing component instances, our GUI code is mostly React and CSS.

WASM engine performance has not been a problem for us, instead we are constantly looking forward improvements in the devex department: debugging, profiling and modularization.

One of the largest challenges of the platform we face today is the heap size limit. While Chrome supports up to 4GB today, that's not yet the case for all browsers. And even with that, we are still discovering bugs in the toolchain (see this recent issue filed by one of our engineers) https://github.com/emscripten-core/emscripten/issues/20137

The challenge of the perf-testing at scale in our company is helping developers to detect perf regressions when they don't expect them - accidental algorithmic errors, misused caches, over-rendering React components, dangerously inefficient CSS directives, etc.

Moving onto the project, let’s first install Emscripten from their git repository. Emscripten will compile C into Wasm code. An important note is that I will be using Mac OS for this project. If you want to follow along using Windows, use this link. To Begin, open your terminal and clone down Emscripten with:

I got pointed to this one here: https://github.com/emscripten-core/emscripten/issues/15487

If you want to do it, go to town. This is the only reference I could find to anybody targeting wasm with i2pd frankly I really hope the person inquiring in the issue is also you.

Right, and if that momentum is going to last 20 years, then that's going to dictate what's a good strategic decision and what isn't for the next 20 years. Thanks for letting me know what the good options might be when my infant daughter is halfway through college, that doesn't help me save for it in the meantime.

Prior familiarity is a very good reason to pick an option for a greenfield project if you're operating on any type of serious budget (time or money), especially if you need to hire others to help out. There's also the annoying reality that most libraries for new/up-and-coming languages are simply inadequate, despite whatever claims they make.

For instance, one of my personal side projects involves getting familiar with WebAssembly (note: not on a serious budget), and I'm using emscripten to transcode because that's what the internet seemed to think was the closest thing to a standard toolkit. I found a bug simply by combining two pieces of example code from Emscripten's own documentation (you'll note I'm transcoding from c++ due to prior familiarity): https://github.com/emscripten-core/emscripten/issues/17143

This is not a dig on emscripten per se, merely pointing out that it's probably not mature enough for the stress of corporate-scale development, where you encounter all sorts of crazy edge cases well beyond the sample code. Java over the years has obtained that level of maturity. The edge cases are largely solved or at least known, and there's an army of experts and consultants ready to help if there's a problem. When time is money, that matters. It determines the risk profile of any project, greenfield or otherwise.

Java's momentum hasn't stopped, at best it's simply slowing. And at this rate it'll take decades to come to a stop, and decades more to recede to any meaningful degree. I'll also point out that C is very much alive and well in the embedded world. Plenty of job postings looking for C experience explicitly.

The "Metaverse" is a complete joke, and among gamers, Valve has a way better reputation than Meta. Why would they want to dilute that brand?

They already have their own platform (Steam), OS (SteamOS), VR headset (Index), their own Windows translation layer (Proton, https://github.com/ValveSoftware/Proton), their own partnership with cloud gaming (Steam Cloud Play using GeForce Now , https://partner.steamgames.com/doc/features/cloudgaming), etc.

IMO: As someone with thousands of games on Steam, there's no way in hell I'd want that linked to Facebook. I think they eventually removed the requirement to have a FB account to use a Quest, but they still require a Meta account. Yuck.

This reeks of Facebook recognizing the Metaverse as the failure that it was and opening it up because it's no longer relevant...

Or Valve's Proton[0], a tool for playing Windows games on Linux.

Did you mount it with the correct flags?

there is a hack to try and use your existing windows game install from an NTFS drive, but i don't recommend it as steam will try to save file names that are not allowed on NTFS...plus ext4 is faster.

From a quick search, here's what I found. It looks like you're encountering some common issues that can occur with games running on Linux through Proton, especially with the recent updates to games like Satisfactory that might affect compatibility. The log entries you're seeing related to D3DCompile2 failing to compile shader and the issues with Ternary operator and LinearToSrgbBranching not being defined, suggest that there's a problem with shader compilation. This can often be related to the version of Proton or the graphics drivers you are using. Some users have reported that the game does launch with the -vulkan option but with graphical glitches and lower performance, which indicates that the Vulkan renderer is working but possibly not optimally on your setup. From the discussions in the community, users have suggested ensuring that the latest drivers for your graphics card are installed and, if using an Intel GPU, that the Mesa drivers are up to date since Intel XeSS references were found in the logs. If you're using NVIDIA graphics, make sure you have the latest drivers and possibly set the PROTON_ENABLE_NVAPI=1 %command% to enable DLSS if you're under Vulkan. If you're using an Optimus laptop with both Intel and NVIDIA GPUs, make sure your Optimus setup is correctly configured. Some users have found success by specifying DXVK_FILTER_DEVICE_NAMES=GeForce to force the game to use the NVIDIA GPU. It's also worth noting that if you're encountering issues with DirectX 11, you might want to try forcing the game to use DirectX 10 if possible or look into DXVK configurations that could resolve compatibility issues. Lastly, if none of these solutions work, you could try running a trace with apitrace to gather more detailed logs that might point to the specific issue. If you're still stuck, it would be a good idea to report the issue to the Proton GitHub page or seek further assistance in the game's community forums where others might have encountered and solved similar issues. For more information and to find others who might have resolved similar issues, check out the community discussions on GitHub​​, Steam Community​​, and the DXVK GitHub page​​.
