1. Achievement and challenges in Calc Summary of my activities in 2009, and plans going forward. OpenOffice.org Developer Novell, Inc. 9:00 AM – 9:45 AM November 5, 2009

3. DataPilot improvements

4. Row limit increase to 1 million rows

6. Working remotely from home

7. External Reference Re-Work

11. Originally for caching range names only.

12. Anatomy of ScExternalRefManager

14. Cached entire sheet including non-referenced data. Reference a single cell... Whole sheet gets cached & still a regular sheet.

17. Efficient storage.

18. Works better with .xlsx import.

20. ODF import/export – populating cache from, and dumping cache to, <table:table> structures.

21. Excel import/export – modifies the way cached data are loaded and written. SUPBOOK, EXTERNNAME, XCT, and CRN records.

23. Eike Rathke

25. Integrated into DEV300_m38. A big load off...

27. External reference listeners added.

29. Had to be re-implemented.

30. Some are yet to be fixed (database functions).

31. DataPilot Improvements

32. Field popup window Before After

34. Easy access to field members' visibility.

35. Pop-up window; not a dialog.

36. Bare minimum; just enough functionality.

38. Larger font size.

39. Submenu-capable menu control, dynamically populated (to be used for autofilter later).

41. Single item buttons.

42. Keyboard access.

43. Accessibility support.

44. Scheduled for 3.3 inclusion.

45. In progress in koheidatapilot03 cws

47. Field members

48. Subtotal

50. Row Limit Increase (1 million Rows)

52. Natural progression of how people use spreadsheet app; quasi database.

53. Interop with Excel 2007.

55. Ordinary-sized documents should not be affected.

56. More rows, more data. Wait and see approach; let's increase the row limit, and see what happens.

59. Automatic page breaks – single rows, distributed semi-evenly from 0 to MAXROW.

61. Flat segment tree for hidden and filtered attributes.

62. Flat segment tree

64. Segments don't overlap.

65. Neighboring segments have different values.

69. Solution: store page break positions in ::std::set separately.

70. Result: pagenation now ~0.1 second.

72. Solution: Perform pagenation only when necessary.

73. Result: CPU usage down to ~idle during print preview.

78. Use ::std::vector instead of Table to store sorted data to avoid excessive array re-allocation. Don't forget to call reserve().

80. GTK's progress bar quite expensive to draw.

82. Note positioning at higher rows.

83. Maybe other stuff I haven't thought of.

84. Other On-going Work Worth Mentioning.

86. Needs ODF file format change.

87. In progress in calctabcolor cws.

88. Text import filter enhancement

90. On-going in koheicopyborder cws.

92. Important for Japanese users. Perhaps usable for Chinese users (Pinyin)?

93. In calcphonetic cws.

95. Display in cell

96. IM interaction

97. Automatic decimal adjustment

99. Improved usability for keyboard users.

103. More visual feedback

105. Become your own expert – code analysis, class diagram, symbol database.

106. No face-to-face talk, limited to emails, IRC – occasional voice communication and periodic face-to-face meetings helpful. Build trust.

107. Unable to share hardware – get your own, invest wisely.
