Bringing back some old code

I used to work an Gimmie under the mentorship of Alex Graveley and then started Mayanna with Alex Gabriel. At some point while staying busy on that trying to figure out the memory leaks I ended up prototyping this.

Here is a quick demo of a semi working sidebare.

Just for the heck of it! Again another clutter update!

Here you go! Just to prove that its still working! Voila

Things I feel like or need to do ?

I am 24 now so here is a list of 24 things I need to be doing or feel like it.

  1. Get all issues listed in the Zeitgeist TODO list done
  2. Finish studies/exams
  3. Improve my Salary
  4. Visit my girlfriend
  5. Visit my mom and brothers
  6. Visit my dad
  7. Lose weight
  8. Visit my aunt more
  9. Start porting at some point all Zeitgeist providers to Mayanna
  10. Start working (by helping Marina) on the GNOME Shell
  11. Work with C
  12. Work with Mono
  13. Learn to drive properly
  14. Go out lindy hoping
  15. Go out juggering
  16. Go out karaoke
  17. Traveling 1 month to India or China alone
  18. Learn to play an instrument (guitar or piano)
  19. Catch up on LARPING
  20. Look for a Job (anything with GNOME or OSS)
  21. Find a bigger better place and move out
  22. Buy a hybrid car
  23. Teach my girlfriend and little brother python
  24. Finish a FPS Game

Now I really don’t know how much I wil lget done befroe I turn 25 but I am going for 1,2,3,4,5,6,7,8  and 14 for the next two months. Wish me luck!

Another lame approach on Clutter

OK i think this is it for the next 3 days! HEere is my latest approach! Needs more love but i think it does a good job :)

Here is the new approach

Clutter UI gets minor update

I just tried to understand more about clutter by improving my first clutter prototype. Now I can scroll left and right! Before I could only move in one direction! Sometimes it jumps though but ends up on the right item. Will check it out later.

I am trying to find some middle ground between this view and Kalle Perssons mockup.

Here is the Video.

New thoughts on GNOME-Zeitgeist

After a not so perfect exam I decided to go crazy on Zeitgeist. Here are my new thoughts:

1. Clutter: First I decided to fiddle around with clutter ending up with THIS. So now I learned more about clutter and decided to give Zeitgeist a nice alternative UI. Most probably Kalle Perrsons mock up. The concept will is zooming into each day only showing 5 days at a time. Its pretty simple.

2. More data providers: Problem is, for me to log the activity, the application used to edit or open the file has to insert its data into gtk RecentlyUsed. Most GNOME applications do that. However some of the applications I use don’t, e.g: Eclipse, VLC, Firefox and Rhytmbox. We will write plugins for them if we find the file (mostly XML or SQLite) with its usage history. Once found we will drop a file monitor taken from “Gimmie” on it and scan for changes to notify Zeitgeist to log. It is done with Tomboy already (Just copied it from Gimmie). We will be applying this mechanism on the current Firefox and Evolution plugin. Soon Rhythmbox and Pidgin plugins will be written. Once done we can start working on a ……..

3. GTK Bar: My idea would be implementing a bottom bar (I will call it activity-bar) displaying the timeline of my day, which I can scroll through. This could actually replace my task bar. This is just an idea though! A little search bar on the side wouldn’t hurt. There will be an icon to open a more sophisticated view of your activity history (the current Zeitgeist view). One should be able to quick tag data/activities in the activity-bar.

4. Tags: Tagging in Zeitgeist works like charm. Even the most common tags are displayed as filters on the top bar. However tagging itself can be a pain in the ass. We need to be able to multi select items and tag them all together.

5. Automatic tagging: Wouldn’t it be neat if once could set up some kind of task manager that can get activated. During the time its running every activity should be tagged with the task name, until its deactivated. Even activities should have their blacklists like in relationships to prevent tagging some unrelated items.

6. Nautilus tagging: It would be cool if one could tag items from Nautilus and write them into the Zeitgeist database.

7. Related Items: We were thinking of how one could define relationships between Data. We came up with three categories of relationships:

  • Tags: Items sharing the same tags are definitely related.
  • RDF: After reading about Organise Framwork I got in contact with Sebastian Faubel and I was impressed. We hit it off really well and are currently planing a workshop in Nuernberg to work somehow on finding an intersection point for both Projects. If we can feed the data we collected with RDF, figuring out relationships should be easy as hell.
  • Behaviour based relationships: Will not write about it here since it is part of my BSc Thesis and Thorsten’s PhD work. But it is possible…

Another feature should be a blacklist to determine that some items should not be related. No one wants to see porn and work together in one window.

8. Plugin Manager: We need to be able to activate/deactivate data providers thus enabling/disabling logging.

9. Provide GNOME Do with our logs: By now everyone is using or heard of GNOME Do and with docky rocking I thought why only provide the user with applications and songs why not use Zeitgeist to figure out which docs and websites have been used lately and display them in the dock. Thus making a point 3 irrelevant.

10. Time machine functionality: Why not store the first occurrence of an editable file and then for every following activity of this file store the “diff”, making it easy to restore any kind of editable file by applying the patches sequentially from the first occurrence till the timestamp. I know there are projects like wizbit out there tackling this issue, but they do more complex stuff. For these purposes i think its enough!

Federico has been helping us out alot lately and I hope we can find some time to give him a better demonstration of what Zeitgeist can do soon.

As for now I will leave you with my thoughts and call my girlfriend :)

Playing with Clutter

To learn clutter i started fiddling around trying to build a new UI for Zeitgeist. A pre-alpha-protoype would turned out to be….Zeitgeist UI 2

its in the bzr repo just pull from there.

try it be running sh zeitgeist2.sh (there is a 2 hidden there)

Here is another mockup from Kalle Persson

Zeitgeist improvements

To sum up we finally added evolution sent mail support! Though a bit buggy it is still pretty usable. Firefox now also takes ur bookmarks into Zeitgeist. I created a new mockup of how i would like the UI to be. This will require clutter so stay tuned for the UI makeover! Here is a quick dirty ugly mockup

Another cool feature I am working on is the relationship managment! After talking to David Siegel he introduced me to predix. I did not start implementing it yet into Zeitgeist. I got in contact with my friend Diego from school and we started looking for an algorithm that can determin data relationships and behaviour patterns based on a timeline of uniformly distributed data activities. We both agreed on “A priori” being the best solution however Diego started implementing his own idea of “temprature based” relationships. As in the closer the events to each other the higher the possibility of them of being related. This was then extended by a frequency/priority variable. Its stil lnot very stable but its a good start! It managed to figure out that youtube, facebook and my bankaccount have a relationships ( I usually check them in specidifc time intervals but not in that same order )

That is it for now got to study.
