Re: Date query question

Another possibility (which I mentioned initially when we discussed this in IRC) is to use a 2-dimensional UB-Tree index. This would be the most efficient way, both in speed and in size (only a single index is required). (class +Proj +Macropisobj) ... (rel sDate (+UB +Aux +Ref +Date)

Re: First post

Declarations: I have now experience in actually using any graph databases. One could simply store the pilog declarations as lists or symbols in the DB, as I understand it, this is what Regenaxer did in the mentioned case. The other way would be to model the data as pil DB schema, as Joh-Tob

Re: later vs. co

Great! To add to the dialog, I am not surprised by co/in-row being similar. I might have actually thought that co would be slightly slower. This task is CPU bound which won't get any benefit from switching coroutines, whereas later spawns new processes (workers) to take advantage of multi-core.

All right, but shall you need some auto-scheduling, to YU know where to look! Le 17 nov. 2016 12:54 PM, "Henrik Sarvell" a écrit : > Hi Rafik, > > Nice stuff, but I don't need that magic, the goal here is simply adding > humans to projects and displaying the schedule to see

Re: Date query question

Hi Rafik, Nice stuff, but I don't need that magic, the goal here is simply adding humans to projects and displaying the schedule to see who might be available to do new stuff at some point in time. On Thu, Nov 17, 2016 at 12:15 PM, Rafik NACCACHE wrote: > HEy

HEy Henrik, Not related by U wrote a project scheduling library and a tasks parser for natural language in Clojure, You might want to take a look on it here: https://github.com/turbopape/milestones There is one online dome here: http://turbopape.github.io/milestones/ I'll be happy if you can
