Virtual whiteboard for sketching hand-drawn like diagramsProject mention: Excalidraw+ | news.ycombinator.com | 2021-05-04
Excalidraw is horrible for this purpose! Don't use it!
There are 2 huge issues.
1. The biggest issue, it does not propagate selections so the interviewee selects something to highlight what they are talking about but doesn't realize that the indication the object is selected does not appear on the interviewer's version of the document. It makes talking about your diagram nearly impossible.
Google Slides doesn't have this problem
2. Excalidraw has this horrible design where placing a shape actually places 2 objects, a shape object and a text object. You type some text and then try to move the "labeled object" and only one of them moves. This is different than every drawing program in existence for the last ~35 years and is a bad UX

🦉Data Version Control | Git for Data & ModelsProject mention: [P] Integrating Git, DVC, and MLflow into one | reddit.com/r/MachineLearning | 2021-04-26
Hey r/MachineLearning. I'm one of the creators of DAGsHub, and I wanted to share something cool that we've been working on. DVC (dvc.org) and MLflow (mlflow.org) are two open-source projects that are very widely adopted, each for its own specialty. DVC excels at data versioning, and MLflow is used for many things (it's actually multiple tools combined into one), but mainly for its experiment tracking capabilities. Both tools have a built-in tradeoff – since they are open source, setting up storage for DVC and a central tracking server for MLflow can be a pain – requiring you to create cloud accounts, add permissions, and more.

Peer-to-peer shared typesProject mention: Kanban board in one HTML using localstorage | news.ycombinator.com | 2021-02-15
For shared use and remote storage, I'd consider using CRDTs like yjs  for instance.
Should be pretty easy, local-first, and allow synchronous as well as asynchronous collaboration and syncing. Even p2p over LAN, webrtc or whatever (I'm unsure how to do local peer discovery in a web browser, on the desktop you'd simply use link-local multicast/avahi (DNS-SD)).
