Root libs and bytestreams

A couple of one-off tasks today: 

1. Make sure I can compile against root libraries in xcode in the latest version of root.
2. Create a bytestream readable by clusterization, for testing.

The idea with (2) would be eventually to make an xml file with a schema which describes SCT hits for a few vents (max 10) for testing various parts of the SCT code. Initially I'll make one which refers to events using rod/link notation and then finally one which can use detector coordinates, although this will need an additional cabling file.

So stages of this task (for today) are:

• chop an existing bytestream file, read it
• change parts of the file programatically, read it
• change the file using an xml event description, read it
• make an xml schema for the event description

...and for the future:

• read a cabling file in the same program
• change the xml schema to allow detector coordinates
• read and create events using detector coordinates

Side tasks today include: looking at the OKS database to see whether we can use it, either directly or in its COOL form, and possibly looking at how to make a SOAP request to the AMI database.

Noon: Task (1) complete and written up here, under 'ROOT and XCode'.

Clusterization and dashcode

Awaiting Bruce's new (COOL version 2.0) database, I'll update clusterization to rip out any reference to ChannelStatusAlg. I have already taken all the functional code from the CTB04 algorithms.

I should also make a couple of desktop widgets for detector navigation using Dashcode, since the license for this runs out on the 15th and the new replacement version looks like its part of a ~$500 budle, at least until Leopard arrives.

Over the past week I've been helping Luca to understand dynamic html pages. I'll put the tutorial material on my TiddlyWiki.

New Beginnings

This blog will take over from the local wiki page at CERN, and should be used in conjunction with my TiddlyWiki notebook , the idea being that this will be a kind of diary and the notebook will keep track of the 'products' I make and the gems of information I need to keep track of.
