Unexpected Relationship

Monday, November 1st, 2010

Recently I needed a Python fix, Monty Python that is. I tried to watch the Spanish Inquisition on Netflix. Firefox (3.6) kept saying the Silverlight plug-in has crashed. Reinstalling Silverlight did not help. Luckily, someone else had already solved this one.  Silverlight would not run because the Windows Tablet PC Input Service was disabled.  I figured I did not have a tablet PC and was not using pen input.  Silly me.

I re-enabled the service and started it.  Silverlight ran fine after that.

Ubuntu Lucid Lynx upgrade breaks Grub boot loader

Thursday, May 27th, 2010

Today I upgraded my laptop, which dual boots Ubuntu and Windows 7, to Lucid Lynx (Ubuntu 10.4).  Towards the end of the upgrade it said it was upgrading Grub (the multi-OS boot loader) to Grub2.  It then asked me some questions about which partitions to modify.

Apparently I answered wrong, because when the upgrade finished and I rebooted, I got an error message from Grub: “Error 4: Symbol ‘grub_puts_’ not found“.  I ended up at a prompt that said “grub-rescue>” where very few commands worked.  Even “help” was not recognized.

Thankfully, others had blazed the trail.  A little web searching turned up a procedure for repairing the Grub install.  (Note:   the first command should be “sudo fdisk -l” with a space dash lower-case L).  I just booted from the Ubuntu LiveCD and followed the procedure.  That resurrected Grub and allowed me to boot successfully into Linux.

Well, as you might have guessed, my Windows 7 boot had also been clobbered.  To fix that, I had to boot from the Windows 7 CD and follow these instructions.

Finally, here are a couple of other informational references for Grub 2:

Many thanks to those who went before, battled the dragons, lived to tell the tale, and took the time to tell it.

Terra Vista kills to_vsb.exe

Friday, April 30th, 2010

I have a Terra Vista project big enough that it takes about 6 hours to convert all the OpenFlight that gets generated to the fast-loading .vsb format.  I use the command line version of the to_vsb.exe tool because there are too many files for the GUI version to handle (because it tries to put them all into its scrolling list boxes).

I was nearing my delivery deadline, so I was doing some Terra Vista processing, and converting some .flt data that had already been generated.  I was waiting and waiting for to_vsb to finish.  Finally I decided to check the processes in the Task Manager.  to_vsb had disappeared!  I finally figured out Terra Vista was killing it, but why!?

Presagis Support had an explanation:  Terra Vista invokes to_vsb to convert its output.  When it is done using to_vsb, it kills all the to_vsb processes.  Not an elegant bit of programming, that.  Anyway, mystery solved.

Presagis suggests that if you want to run to_vsb and Terra Vista concurrently, you should make a copy of to_vsb.exe and rename it so TV won’t kill it.

Skype won’t go “Away”

Tuesday, March 30th, 2010

Skype LogoI’ve been traveling and using Skype to phone home.  I noticed that the people in my Contacts list always looked active, but often were not.  Then I noticed that my status was also showing active.  The solution is to go to Skype Tools -> Options…, change your inactive time from the default 5 minutes to some other value, hit Save, then go back, change it back to 5 minutes or some other value, and Save again.  I found the solution here.  I’m using Skype 4.2.0.155 on Windows 7.
