1. The QS
How did we build the new query
system?

2. Development Team
Andrew Gilmartin, Chuck Koscher,
Evans Lin, Hisham Shahtout

3. 1. Interesting parts of the QS
2. Experiences building the QS
3. Lessons learned for the DS

4. Tools
modern, but not too modern

5. NetBeans 6.[89]
technique sharing, tool building

6. Java 6
generics, annotations, oh my!

7. Tomcat 5.5
servlets are components too*

8. HAProxy 1.4
http://haproxy.1wt.eu/

10. Oracle && MySQL
valuable || expendable

11. ActiveMQ 5.4
wicked fast loose coupling

12. Spring 3.0
Really?

13. Spring || EJB || ???
reaction, refinement, replacement,
re-implement, rejoice

14. POJOs || Deployment
Descriptors
i just ( do || describe ) objects

15. Dependency Injection
|| Coded Configuration
more than one main()

16. Functional Interfaces ||
Featureful Interfaces
a little well done is enough

17. Spring Experiences
some tales are told a little later

18. Design
and not doing architecture

19. Controllers, Services
&& Coordination
insides and outsides

42. Spring Experiences

43. Coming up to speed
books are useful … for about 5 hours

44. Is that answer for
Spring 1.x || 2.x || 3.x?
rummaging around the net

45. Deployment
Descriptors
they’re back and now called contexts

46. Spring Beans
&& Java Properties
Where do I defined this thing?

47. XML
XSDs, id(s) || name(s), conditional
sections

48. Runtime Configuration
Errors
scripting without the support tools

49. Bondage
bound to Spring as much as you are
to any framework

50. It might be there
but not designed as expected

51. Development lessons
from the QS to apply
with the DS

52. Undervalue your own
ideas
the view from the backside of the
leading edge

53. Existing wheels
are generally
well designed
use code libraries … which are
sometimes your own

54. Use the API correctly
150/second to 2000/second

55. Stopping
buck-passing
artifacts, costs, choices

56. A does not follow B
right away
synchronization and the
ReadWriteLock are your friends

57. Pick a monitoring tool
as-soon-as-possible
instills design for management and
monitoring

58. The data is already
stale
design data for management and
convert data for use

59. Priming takes a long
time
pool XML parsers

60. Data conversion takes
a longer time
break it up into multiple parts

61. Spring Contexts need
support tools
we have one, we need more

62. Design small
interfaces
federation of cliques

63. Front-Controller vs
Servlets
I want my componentization back

64. Keep talking
especially with distant developers

65. :)
