0.1 MVP - minimum viable product

• Rudimentary single script-based product
  • has 2 files: the script (executable) and a data storage file
• User can run a shell script
  • script checks for existence of data storage file
  • if file exists, 'cat' file and "sort -n"
  • format for data storage file
    • how the date is stored so that sorting is natural, via the Unix 'sort' ?
  • location of the DSF can be set within the main cpim.sh script
  • editing of items happens manually, to the Data Storage File

0.11 bug fix

• the -c (configuration dump) did not show project home page Fixed. Now it shows a line: 'Latest news:' and the Github page URL.

0.2 Tagged tasks: support multiline items in Data Storage File

• change to the DSF storage format
  • fundamentally shifting from a line-by-line to a structural format
  • adopting a 3 -field system
    • flags, hash, payload text
  • having both Groups and IDs encoded in the
    • max. no# of groups is 4095 (12 bits)
    • max. no# of IDs (=tasks) is 262143 (18 bits) = the 'hash' would be 5 characters long
  • immediate benefits:
    • moving of multiline tasks as entities (they won't split)
    • separation of user-specified text content from data headers

0.2.1

• calculator (how many days to due date)
  • shows somewhere on the line, when a task list is printed
• sort the task list by "days left, ascending"
• decide upon robust order of items that do not have due date

0.3 WIP: Not yet thoroughly planned

• interactive mode introduced to The Software => now user can issue keyboard commands and work more efficiently
  • before interactive mode, the only way to run The Software was a non-interactive shell execution.
  • interactive has 3 main operations d - show dashboard t - show tasks view c - show calendar

0.4 WIP

• adding calendar functionality: browse by week

• from NOW, enable showing what is the date 1 calendar week ago N calendar weeks ago

  • the same, but into future What date will it be 1 calendar week from NOW What date will it be N calendar weeks from NOW

• calculate the amount of whole calendar weeks between two points in time

2.0 Major:

• 'search' plugin introduced
  • "The world is a supermarket of things that are available through information search costs."
  • searching is a static scraping + API support for getting more information regarding tasks
    • helps estimate better
    • information consumed by User, no programmatic intelligence yet

Free-floating plugin concepts

• plot PPF
  • take the tasks
  • permute execution order
  • calculate what's possible, what's "Good" (optimizer)
  • ppf meaning production possibility frontier (economics term)

Underlying technical components

• calendar
• editing (refreshing) a file, in-place
  • for doing prioritization
    • in cases the simple format is used

DSF - The data storage file

DSF exists in the versions of The Software where data is stored statically in a local file. This is the data storage file. In 0.1 release the file format was simple; a number followed by followed by a string of text. Thus each line described a task with a priority number.

The PIM contains an easy interface for daily use. User can either check the Dashboard one-time via shell, just by running the cpim, or start interacting with the software for longer periods of time.

Adding and editing items is possible via command line parameters, reading lists from ASCII text files,

• 'checkup' plugin Control the progress of your plans

  • requires the categorization (binning) of plans
  • single key, single metric?
  • drill down with another key (or command line switch, accordingly)

• enable recipes for fulfilling tasks. Recipes contain intelligence that aids the Win-Holistic Intelligent Priority engine (WHIP) giving your sound advice and automating things

• adding server functionality. Currently the cpim is a client-side script only. A server brings benefits of roaming (mobile interface possible) and sharing schedules / other PIM information between multiple persons

• mobile device support (once server is set up and running)

  • serves the app as a SPA (single page mobile app)

• GIS support on mobile devices

• once server functionality exists, there is possible:

  • add group optimizations
  • add ridesharing scheduling

• In the future, interaction with Apple's PIM format will be added Enables easy integration to iPhone, iPad, Mac and other Apple products
