The concept of viewing activities as DAG is going to be huge and ubiquitous, I think. This applies to any activities of humans, organizations and computer systems, and hybrids of those three. One of the most fascinating epiphanies I've had recently is exactly that the purposeful behavior of these three kinds of actors can be decomposed as DAG with a relationship meaning "contributes to fulfillment of a need". So cong…

What do you mean "is going to be"? Activities as a DAG is how it's already done. This is how Work Breakdown Structures are generally constructed. Tools like MS Project can display them as Gantt charts or network diagrams or as an outline (where you can set the dependencies used to create the Gantt and network charts).

Very few human tools utilizing this concept are common to any degree.

Github Issues doesn't have issue dependencies at all.

Salesforce "Action Plan" view is a plain list, no deps at all, as far as I have seen.

Todoist doesn't do dependencies.

Bugzilla does dependency graph, wow: https://bugs.gentoo.org/showdependencytree.cgi?id=706426&hid...

I guess JIRA supports deps, but I don't think it's the tool which people here would want to use to be able to decompose their big undertakings, especially personal ones.

TaskWarrior supports deps, but it's not a mainstream tool and deps were fairly hard to use in it AFAIR.

The ads block buttons in the UI, on a pixel 3a. Is there a paid version without ads?

Sorry about that, it should be fixed now. There isn't a paid version at the moment, but there's a web app at https://i.ntention.app . If you're on android, it should ask you if you want to add it to your home screen - if you do, it behaves very like an app.

It may not be common in the tools people here use, but it's common in the tools used by major engineering organizations.

My point isn't that it's a bad idea, it's that it's not a novel idea. PERT is another way of graphically representing activity. If you aren't concerned with the time, it's your DAG.

I’m not seeing how DAGs are distinct from forests (sets of trees) or outlines. They seem topologically equivalent.

Level n nodes can have arcs to level n-m nodes provided they aren’t ancestors. In addition nodes can have multiple parents.

So can trees. File systems do this all the time.

Most file systems aren’t trees, most are some more flexible graph. You can get away thinking of them like trees as long as you’re not writing a correct program. (see also: links, bind mounts)

Trees have a formal definition that precludes this, that’s why we call them trees and not graphs.

What about when my tasks are cyclic? 1. can’t get up because haven’t eaten and too hungry 2. can’t cook because can’t get up 3. can’t eat because can’t cook Didn’t think of that did ya buddy! Day 2 of quarantine is going very well.

step 1 is your achilles heel... maybe stash crackers and juice under your pillow? /s>
