Ummm, is that the right name for this place? Miller thought it was. Anyway. It’s a collection links to textures and blender tutorials (with a SecondLife/Open Simulator bias) and other useful things that I need to remember how to do and where to find them. Occasionally I might even write a tutorial or two of my own.
Logan and I like her old HP Deskjet 1010, we were a bit peeved when we “upgraded” to Windows 10 and it was no longer in the list of printers. We found this tutorial on the web and it worked like a charm to put it back again.
Well-impressed. Thanks mate (-:
dd if=/dev/zero of=/dev/hda
dd if=dev/urandom of=/dev/hda
dd if=/dev/random of=/dev/hda
- Using /dev/zero is a load quicker, but not as thorough.
- /dev/urandom takes longer but is more thorough and doesn’t require you to be doing anything on the machine to help create the random data.
- /dev/random is slower and more thorough still and requires monitoring the system to generate entropy.
Excellent explanation here: http://superuser.com/questions/359599/why-is-my-dev-random-so-slow-when-using-dd
Logan wanted a way to move one table from a MySQL database to another database on a separate server. We found this idea in a closed discussion on Stack Overflow
mysqldump -u user dbname tablename -p > tablename_dump.sql
The thing that I thought was really cool and that I didn’t know before (‘cos I didn’t read enough of the manual) was that you can put a single table name after the database name and just get the structure and data for that table. You could then use that to send the new table and its data to your new database. In fact, the guy that posted it actually put it like this…
mysqldump -u username yourpass dbname tablename -p | mysql -u user secondDB -p
…which I haven’t used, but looks like a really neat way to do it.

I found myself scratching my head for a while over this while modifying an LSL script to run on 3RG. The error message was:
Error CS1009: Unrecognised Escape Sequence
It turns out that it’s an C# compiler error caused by an “unexpected character followed by a backslash in a string”. In my case I had a message to llSay() and I’d used “\n” to create a new line and then inadvertently put an extra backslash, something like this:
llSay(0, "Some message \n\Some message on a new line");
In SL, the script just compiles, but on 3rd Rock Grid (and presumably many other Open Simulator grids) it fails with that error and the editor claims it’s on a line way , way above where the error actually occurs.

SL Viewer -> Advanced Menu -> Debug Settings -> MeshMaxConcurrentRequests
The description says “Number of threads to use for loading meshes”. Apparently if you can’t see all of a mesh build, or maybe someone’s hair is missing or something, increasing this setting might enable you to see more. I have no idea whether it works, it was just something I saw in a discussion one of the Blender groups.
Neat trick to help stop shaky cam. You could probably use this with a space navigator too. http://youtu.be/Fj6fMcJ18aA
