Leo Danelowicz’s Loft

Wednesday, November 26th, 2003

I built a shelf for the garage using 2×4’s and 4×8 chipboard sheets.  When the shelf was finished it was quite sturdy.  It reminded me of the loft that Leo built up in Stackwyck.  Now that was solid.

Movies

Monday, November 24th, 2003

We watched “Bridge Over The River Kwai” last night.  It’s been a few years since I saw it last.  It’s much better than I remember.  We also watched the Robin Hood Movie with Errol Flynn.  It was much better than the stuff we get these days.  The children really enjoyed it.

Tomcat / MySql Hang

Tuesday, November 18th, 2003

Since I read that there’s an 8 hour timeout on the mysql jdbc driver I stuck in some cron jobs to restart tomcat at 0, 8, and 16 hrs.  It’s been about 3 days and I’ve had no hangs.  I’ll have to figure out the proper solution some time.

Cast Iron Heat

Friday, November 14th, 2003

I was cooking dinner on the wood stove the other night.  It was just some tortillas and I was melting cheese on them with a cast iron skillet (fajita pan).  I thought it would be neat to do it that way as I had the wood stove really hot.  Naomi was cold so after I finished with the tortillas, I put a trivet on the dinner table and brought in the hot skillet.  The heat radiated very nicely and warmed us all up.

EJB Performance

Friday, November 14th, 2003

You have a large EJB based application running on WebSphere 4 but the performance is really rotten under load.  You’re about to upgrade to WebSphere 5 and one of the engineers suggests that since WebSphere 5 supports local interfaces you should recode EJB access to use local interfaces for the project.  All the code’s running in one JVM so it should improve performance, right?  What do you say?

Scanner on The Fridge

Thursday, November 13th, 2003

Naomi wants to know what temperature the fridge is so I’ve rigged up some KPB wire from the fridge to the scanner on the water heater.  I’ll have to take off the J type thermocouples and switch them with KPB wire before switching the scanner over to type K.  It’s a Contronautics CN606.  The manual is here: http://www.contronautics.com/Manuals/CN606.pdf  I could do it in Java, but for tonight I guess I’ll just use the front panel to reconfigure it.

Squirrelmail Is Nobody

Thursday, November 13th, 2003

From time to time I can’t get to my squirrelmail prefs file.  The owner changes to apache for some reason.  I do chmod -R nobody.nobody on the data directory and all returns to normal.  I’ll watch for a pattern.

Solution

w.bloggar

Thursday, November 13th, 2003

This is a test of w.bloggar 3.02 posting to roller on my site. It’s neat but I was hoping for something which would integrate the upload file and insert image functions into one process.

Blog Extracted

Thursday, November 13th, 2003

http://new.blogger.com/home.pyra was a great way to get started with web logging.  Roller’s installed and working here so I copied the content over (by hand one entry at a time preserving dates) and now it’s all here in the Stuff category.

JNDI Caching

Thursday, November 13th, 2003

Here’s a page from theinfocenter on how to set up JNDI caching for WebSphere 5: http://publib.boulder.ibm.com/infocenter/wasinfo/index.jsp?topic=/com.ibm.websphere.nd.doc/info/ae/ae/rnam_example_behavior.html


I’m not convinced about the wisdom of this: http://www-106.ibm.com/developerworks/java/library/j-ejb0924.html but there are several patterns which advocate caching of JNDI.  This would seem to be a pattern for container vendors not developers.
