7:30 – 2:30

  • Clean up and test alert adding in jython – done
  • Start on the AlertServlet – particularly how to add, clear, and delete(?) an alert RESTfully. Started. Servlet runs and posts the alert list xml, but doesn’t perform any operations
  • 1:00 meeting at Anne’s – nope, postponed

Feldman Project Log

Tuesday:

  • Shortened signal wires to strain gauges so more of the wire is shielded
  • Strain Gauge came loose on second sensor stick had to redo it.  Did not use enough silicone to hold the connections in place
  • Found out glut is event based.  Need to either use standard GL libraries or freeglut.

Wednesday:

  • Finished repairing second sensor stick
  • Started putting the whetstone bridges on a board so I wouldn’t have to worry about the wires coming loose all the time
  • Had trouble finding GL Headers and libraries.  Found out that they are in the Windows SDK.
  • Cold solder doesn’t conduct well.  Connections need to be well seated on the board.
  • Saw that freeglut is still supported and was updated as of November 2009.  Going to give it a try since I am having trouble with the standard GL libraries and from the description freeglut is designed to replace glut because glut is no longer supported and outdated.  Freeglut supposedly can be used in a non event based way.

  • Continue configuring XAMPP- done
    • Visibility not working!
    • Turned out the Tomcat for XAMPP uses Java 1.5
    • replaced jre directory with Java 1.6 and everything seemed well
  • Testing XAMPP install package on laptop-13- done
  • added total_budget to budge_centers table, budget to _funding_requests_budget_centers table
  • added FloatItemRenderer to display floats in currenty format (double precision) – need to do DG.validateNow()

  • Logged into LDAT(2) successfully. Asked for a tutorial/walkthough, and who to talk to for direct JDBC access. I may use the scripting service to publish that data
  • More alerting. Need to do the following
  • Add an alert in the Alert Manager
  • Clean up and test alert adding in jython
  • Start on the AlertServlet – particularly how to add, clear, and delete(?) an alert RESTfully

  • Have you done your taxes yet?
  • Meeting with Jim Murphy & Trish(?) Went through Don’s system pretty thoroughly.
  • Added links to help in vis2
  • Add Alert panel to webbapp – started
  • Add code hints to scriptFacades
  • Start on Alert Servlet

  • There is some new data in the employees tables on site. With some poor picking, there could be some real combinatorial problems. Not sure what to do about that right now. Maybe a warning (“Warning, this may result in a very slow return, do you wish to…?) Dunno.
  • Working on adding alerts. Can create an alert and add it into the db trough ScriptObject. Tomorrow, I need to be able to pull out the list of alerts for ScriptObject, and start on the REST component. Last thing will be to add interaction with Python.
  • Speaking of which, I really need syntax coloring and code completion in the “IDE”. Found some syntax coloring that might be usable on sorceforge. Nothing on code completion.

  • continue working on Funding Request editor
    • Save, Request, Send to BF34, Certify, Accept works (updates the status accordingly)
    • Date updates can now be saved
  • working on Triggers to store data logs (SQL’s)
    • mysql> delimiter $$
mysql> CREATE TRIGGER Employee_Trigger
    -> AFTER UPDATE ON employee
    -> FOR EACH ROW
    -> BEGIN
    -> INSERT into Employee_log
    -> (user_id, description)VALUES (user(),
    -> CONCAT('Id with ',NEW.id,' is modified ',
    -> ' from ',OLD.start_date, ' to ', NEW.start_date));
    ->  END$$
Query OK, 0 rows affected (0.00 sec)

Feldman Project Log

  • OpenGL works in a similar fashion to our RCS system so I decided that I’ll make a controller for the graphics simulation.
  • Finally got a second sensor stick assembled waiting for silicone to dry.
  • Amp was running extremely hot.  Lowered input voltage to 5 volts. This helped with the heat but there is less range of voltage change then before.  After shielding the wires and lowering the voltage the idle readings are much more stable.

8:00 – 4:00

  • Meeting with Anne at 9:30. Then I need to chase down what the issues are with my certs.
  • Add alerting capability to JavaFacades.java. I’m thinking another db that can be accessed restfully that has a list of all current alerts. This does mean that I’ll need some level of CRUD to deal with handling alerts (acknowledge, etc, from outside the system)
  • BLACKPANTHER meeting/demo

Feldman Project Log

  • Did a couple tutorials for OpenGL.  Going to continue this over the weekend if I have time.
  • Tried to use  the new sensor rod.  The hole for the motor axis is too big.  Tried to use tape and heat shrink but it would still not get tight enough.
  • Started fixing the other sensor rod.

  • Got a note from Michelle G (LDAT). They want to move ahead. I need to get FGM’s NDA
  • Adding better keyboard control to scripting window. Trapped tabs, going for autoindent. Basics of autoindent are done.
  • Some permissions problem at the fort. Going back in. Fixed
  • 9:30 Meeting with Anne on Monday. Come here first, I guess.

  • Finished attaching strain gauges.  Currently waiting for silicone to dry.  For future reference make sure the first layer of resin is fully dry before attaching strain gauges.  If not you might end up with the strain gauge touching the metal rod.
  • Added a stop_CW(clockwise) and stopCCW(counter-clockwise) so that it wouldn’t get move commands when its collision reaches the maximum force.  Its hard to test how successful the changes I made were until I get the other sensor stick working because the current one acts too erratic.
  • Read OpenGL book
