Hello #mathstodon #math Fedi!
Can anyone recommend introductory (upper-division undergrad/ early grad-level) lectures, lecture notes, or reference texts (in descending order of preference) on multilinear algebra and tensors? Ideally including explicit treatment of applications and numerical methods.

A few more songs by the recently departed Tom Lehrer. We grew up listening to his albums and memorizing every word, sometimes years before we understood what they meant. I've never heard these mathematical songs before.

He approached his limit and then exceeded it.

Just a thought, from a knuckle-dragging biology scientist. TL;DR: I believe there is scope to make the hosting of a peertube instance even more lightweight in the future.

I read some time ago of people using #webAssembly to transcode video in a user's web-browser. blog.scottlogic.com/2020/11/23

Since then, I believe #WebGPU has done/is doing some clever things to improve the browser's access to the device's GPU.

I have not seen any #peertube capability that offloads video transcoding to the user in this way.

I imagine, though, that this would align well with peertube's agenda of lowering the bar to entry into web-video hosting, so I cannot help but think that this will come in time.

My own interest is seeing a #Piefed (activitypub) instance whose web-pages could #autotranslate posts into the user's own language using the user's own processing power... One day, maybe!

Thank you again for all your hard work; it is an inspiration.

Scott LogicIn-browser transcoding of video files with FFmpeg and WebAssemblyThe WebAssembly build of FFmpeg allows you to run this powerful video processing tool directly within the browser. In this blog post I explore FFmpeg.wasm and create a simple client-side transcoder that streams data into a video element, with a bit of RxJS thrown in for good measure.
