usig modern web technologies to develop high performance scientific applications. We built a highly optimized, interactive and exploratory application for single-cell data analysis[1]. it runs purely in the browser with no backend and scales upto 200K cells. similar efforts include the biowasm project [2].
After spending a lot of time testing out different apps, I ended up doing the same. Also orgzly for android works pretty well with org files stored on dropbox!
This has been a workflow that served me well for the last couple of years -
Most of my stuff is on dropbox/google drive for accessing them across different devices. I prefer tools that let me control where the data is and not the other way around.
For all academic papers, documents, I use Zotero. you can use your favorite pdf reader to annotate or take notes on pdf's and zotero will sync these. I also love the feature where Zotero can automatically extract all annotations from the pdf. (I some times save these as an org file)
If I am reading a longform web article or a blog post that I really think is useful and helpful, I also save these to Zotero. The push to kindle extension from fivefilters is an awesome tool that converts webpages to pdf.
I'm currently testing the memex extension from worldbrain to annotate and organize my browsing history.
For all notes, journals, random thoughts, ideas, (both work and personal), I use orgmode. (I recently switched from ZimWiki). Its been amazing so far. So many things are easier to do orgmode although the learning curve for emacs is pretty steep in the beginning.
On mobile, I use the orgzly app for accessing and taking notes! Its by far the best android app I use so far.
