Yes, and you can still download the Agenda disks and play with it - it correlates the information as it is ingested, and displays it in various ways.
The amazing thing is the relationships it points out in your data.
You should look at Lotus Agenda.
Ideally you want a program like that to be able to ingest email and web clippings, these days.
For tetx-based notes, Lotus Agenda was the best ever made. Like many good things, it died.
"Real Programmers don't use GC" is a mantra that is responsible for 90% at least of production bugs, together with "=" being typed instead of "==".
Or do all programs run bugfree the day you write them?
I cannot read a maths book or paper without writing on it.
Microsoft OneNote is cloud-based with syncing, has drawing tools, OCR for image content, handwritten comments, and even a Maths editor, and can organize your stuff. There might even be a symbolic calculator buried somewhere in it. I use it on a Surface Pro; to make the handwritten annotation part work well you really need the Wacom Stylus.
There are a bunch of PDF readers on the PC and Mac which can annotate. I think they all export the annotated PDF, and a couple of smart folders or Google Drive might be enough to maintain a synced system.
Unfortunately, this whole area is one where proprietary is ahead of open source - OneNote and InkSeine are masterworks.
Dave's course is certain to be interesting.
A good way to get up to speed in research IMHO is to look at the problems in publications, and try to reproduce the indicated work. You can do this with fairly old (5-6 years) publications too, usually at that point data sets etc are available.
The freedom of the press belongs to the owner of the press.
Apple obeys Chinese law by not allowing their citizens to bypass censorship , and it obeys US law by providing private information on the Chinese users to the US authorities
Yes, my foot probably contains about two pints of water.
The NSA gets the info, then the CIA takes out selected individuals by lobbying, blackmail or if all fails
The US has argued that the private records of the rest of the world can be searched and divulged at will - why should americans suddenly expect to be treated differently?
If none of the tech-savvy phone corps objected to turning over bulk data, when the process gave them that opportunity, one can conclude that Americans are mostly happy to the surveillance, probably because it gives them an illusion of safety.
I have a tip for our sheepish friends: Appoint a dictator, totalitarian regimes are much better at policing than democracies.
Often statistics are used as a drunken man uses lampposts -- for support rather than illumination.
