What doesn't fit here?
The core of the story has to be technology focused.
- If article mentions "AI" in a sentence and then talks about business economics that doesn't make it tech news.
- Gaming is too many layers removed from technology. There are many dedicated communities that are a better fit for it.
- Transporation is too many layers removed from technology. EVs while use many cool technologies have many dedicated communities that are a better fit for it.
- Entertainment is too many layers removed from technology. While sometimes it can fit here, business or cultural aspects of it are a better fit for dedicated communities.
- Cybersecurity. While it heavily focuses on technology, most of the time it's too technical for most people who are not already invested in it. Should be posted in a dedicated communities unless it has broader connection to other tech areas.
Post guidelines
Title format
Post title should mirror the news source title. If you don't like the title of article, look for an alternative source instead of editorializing it.
URL format
Post URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.

They are using GPUI. Rust native UI framework from the Zed IDE team. I think the creator of Zed is the one who created Electron in the first place, then left. I'm not sure though.
So it should be cross platform
It's a bold strategy. "Electron sucks! Let's see what else these people made".
But seriously, why do I need GPU acceleration for my chat UI?
It's a video player. You want GPU acceleration.
What video? 99.99479% of my Discord experience is text.
A lot of people talk and stream to their friends. If I only needed a text app, I would not use discord at all.
Really depends on the server. The servers I use are driving incredibly rich media: like animated images, video clips, and streaming.
Because rendering things is quite literally the reason GPUs exist, it takes load off the CPU and is more efficient at it to boot.
It doesn't hurt to have the component that is optimized for drawing things to the screen be a bit more involved in drawing things to the screen.
Strictly speaking necessary? No. Does it hurt? Not at all.
Because without it UI changes create CPU spikes
People use Discord for a lot of things. A lot of people use it to stream and watch streams.
Do you like having battery?
