Weekly Summary 30/8/06

  • Guy has created a new community with password change facility - passed I&R and ready to install.
    • Tried to install, but it won't self-register: see bug 1789
    • Guy has put a fix on the merge queue for this...in the meantime we can hack the reg entry....done...appears to work well. Except.....you can change your password with any old password.
    • Mark to reinstall when it passes I&R? How did this error slip through I&R in the first place?
  • Submitted abstract to ADASS 2006 http://www.adass.org:8080/Conferences/2006/Venue/people/participants/abstract?abstract_id=82
  • Planning: using Open Workbench http://www.openworkbench.org/ to create GANTT charts and managed dependencies between tasks.
  • Downloaded and installed Eirik http://wiki.eurovotech.org/twiki/bin/view/VOTech/EirikDemo on a Debian machine. Plastic and AR functionality appear fine. Couldn’t test further due to Window size issues. Installation straightforward - install debian version of R first, then hand edit the Eirik startup script to find the location or libR.so.
    • Tried to install Eirik on Shuna (Bob’s machine). Since I’m not root this involved building R from source using ./config and make. This is fairly easy to do, following the instructions, but care must be taken in the config stage to request a shared library libR.so to be built, and also to set –with-readline=no on Shuna. Unfortunately getting Eirik to run on Shuna wasn’t do-able due to assorted missing shared libs on this machine.
    • However, following several iterations, did get a windows version running.
  • Hardened the hub to concurrency problems and clients passing shit values.
  • Jeff and others are experiencing some AR problems - AR is refusing RMI connections. I also have the same problem from time to time and it’s usually cured with a reboot. Mark’s Plaskit hub doesn’t suffer from this. Suspect it’s something to do with the way the AR deals with IP addresses - a network outtage is enough to screw it up.
  • Finished Anomaly Detection pipeline
    • Looking at deploying stilts at the same time. There are problems with the existings STILTS deployments discussed here. (Fixed by Kona). Get Kona/Mark to install?
    • Standard and Advanced interfaces now done, and registered. All works smoothly, but not very robust to errors in data since fastem locks up waiting for a user response....not a great idea for a CEA app.
    • Created an applet to allow users to simply change their workbench registry settings. This was also a learning exercise for creating a plastic-applet.
    • Instructions for use are here.
  • Finished a prototype Plastic-compatible web page...this is aimed at our own WSA, but also to get DataScope on board.
  • Received request from Noel to smarten up our metadata - we need to discuss logos.
  • Checked Son Of GAIA for Nigel, and found that I can’t run the webstart version either due to missing classes. Probably due to the 1.5 java libraries having renamed some classes. Reported to ussc@star.rl.ac.uk...address is defunct...emailed Mark Taylor...apparently you need to install the JAI package first (not documented!).
  • Assisted Brian getting his weka cea apps deployed to our test registry. We encountered a lot of out-of-memory errors in the registry, and also a particularly annoying bug necessitating the reconfiguration of the registry and changing its authority Id.
  • Assisted Brian changing the registry his workbench uses.
  • Realised that if we have a test registry, we need a test JES, so installed one here. The official release of JES is lacking an astrogrid-security jar, which you have to add by hand to WEB-INF/lib. Catherine has now released a new build, which Mark should test.
  • Thanks to Brian, reproduced the mysterious "Found Resource Document, but had no AccessURL" that has been plaguing systems that harvest from our publishing registry and try to access our date sets. Bugzilla report. It appears to be due to our use of Java 1.5. I've found that most of our old datasets suffer from the problem, but that it doesn't occur in the latest snapshot build of the workbench. Hence we could ignore it - it will go away when we reregister our new services anyway. Left it in Mark and Kevin's capable hands.
  • Republished Plastic site with google analytics code throughout
    • mvn 2.0.5 not yet released, and the bugs in 2.0.4 make site publication a painful process as
      • site:deploy doesn't work in windows
      • site:stage doesn't copy the contents of directories, effectively making multiproject site deployment useless



Actions
(68.2) JDT to give an ROE coffee talk with a demo of AstroGrid
- maybe also including access to UKIDSS data.
pending...


(69.1) JDT and KEA to produce a plan for providing password-changing
functionality for ROE account holders registering for AG.
DONE - see above

(69.2) JDT to pass this up to Noel Winstanley and/or Kevin Benson. DONE - see above

ACTION (70.1) MSH to install the new version of Community.
done by JDT

ACTION: (70.4) JDT to contact Guy Rixon to check that their plans for wrapping
STIL(TS) as CEA services are consistent.
DONE - see above

Thoughts:
Need better cover for MSH's absence
