The first two are what motivated this post, but the rest are hopefully worth your time:

• Hash Functions for GPU Rendering – I’ve been waiting a long time for this to come out. RT here. Now there’s no reason now to use a bad one. Oh, and bonus: Shadertoy version.
• On Windows, Control+Shift+V pastes text into Gmail and other apps without the formatting (I never knew until now…) – or try Control+Alt+V – it varies among applications. Oh, and it’s the somewhat insane combo Option + Command + Shift + V on the Mac. Then I found this list for more on Windows. But the second-best one is missing from both: Windows+Shift+S brings up four different screen clip tools (thanks, Mark DeLoura!).
• Ray Tracing Denoising article by Alain Galvan.
• arXiv now allows researchers to submit code with their manuscripts – title says it all. I’m for it.
• Real-Time Stochastic Light Cuts won a best paper award at I3D 2020; it includes source code. And, here’s a nice blog from the first author.
• SIGGRAPH paper trends in twelve seconds.
• What might cheer you up: free and legal Studio Ghibli screen background images.
