Paper Gestalt

Imaging sharing 

I need to create some image galleries for my garden.  Wish me luck!  But how to choose a hosting site?

Especially, I heard there is some issue with sites claiming ownership of uploaded photos.


Code duplication tools 

The following might be useful

Not open source, but free to use

These seem to be less useful

Another nVidia moment 

I was running Slicer, and suddenly X froze.  Needed to do a hard boot.  (Even /sbin/shutdown was not effective.)

Following the reboot, X was extremely sluggish.  Could not log in through console.  Xorg.0.log was clean, but dmesg had messages such as:

[   65.004180] NVRM: RmInitAdapter failed! (0x26:0x38:1219)
[   65.004198] NVRM: rm_init_adapter failed for device bearing minor number 1
[   65.004241] NVRM: nvidia_frontend_open: minor 1, module->open() failed, error –5

and

Decided to upgrade my distro and reboot.  Still no love.

Eventually a forum suggested this setting in xorg.conf.

Section "Device"
    Identifier     "Videocard0"
    Driver         "nvidia"
    Option "BackingStore" "True"
EndSection

It seems to have worked ??
