13. 14. 15. Small team
16. Varying backgrounds
17. (brilliant co-workers)
18. Diverse skill-sets
19. Whatd I get out of it?

38. Testing affects your design
39. TDD: Test-driven Development
40. TDD: Test-driven Design
41. Flexible design grows out of making codetestable
42. Legacy Code:any source w/o unit tests

46. Why?
47. The world faces tough problems in the future
48. Fuel/Energy
49. Food
50. Water Supply
52. Cyberinfrastructure
53. In scientific usage, cyberinfrastructure is a technological solution to the problem of efficiently connecting data, computers, and people with the goal of enabling derivation of novel scientific theories and knowledge.
54. Large systems designleads to diverse,interdisciplinary teams
55. With the direction of Computational Biology & Bioinformatics
56. 57. Software Development as aCollaborative Game
58. Soft skills are important
59. Speaking in tongues is not allowed
60. Working in pairs, not just forpair-programming ordebugging
61. Impromptu design discussions
(they often include more than just technical folks)
62. 63. Code for Science
64. I wasnt always interested in science/biology
65. 66. Confused looks are commonplace for me
67. YOU > me
68. Biology is an interesting domain
69. 70. I know too much aboutAuto titling & international trucking fees
71. 72. 73. 74. 75. 76. Going forward
77. Test, test, test
78. If not test-first, test-very-soon-after
