openbsd 5.2 seems to be an interesting choice for old pentium one computers.

hplip error: Unable to communicate with device (code=12)

I have a wireless networked HP printer and was getting this error: Unable to communicate with device (code=12). I ran hp-check, hp-setup, hp-plugin, etc. After a few days' worth of frustration, I've figured it out.

The key was this: http://hplipopensource.com/node/216
So after running
Code:
snmpwalk -Os -c public -v 1 ip.address.of.printer 1.3.6.1.4.1.11.2.3.9.1.1.7.0

An STL Template Experiment

Posted 12-18-2012 at 05:05 PM by rainbowsally

Today's features:

  • A couple of ways to work around unwanted C++ compiler warnings.

STL is a freaking nighmare to trace in a debugger so it's not too easy to tell what goes on in them but one thing became quite clear and that is that iterators are generic pointer types internally, which makes sense since STL needs to deal with so many different types.

A new approach

Tooling Up. ui-tool (QT4 ui file utilites)

Posted 12-15-2012 at 10:16 AM by rainbowsally
Updated 06-10-2013 at 04:17 PM by rainbowsally (bullet list not showing correctly + typo fix + parag alignment)

UPDATE: (2013-06-10) There's a stand-alone version of the uitool here.
http://www.linuxquestions.org/questi...3-06-10-35568/

It's part of the next libLQ-qt/mc2 project but that lib is not ready to fly yet.

--------
Note: This is now part of the libLQ-qt download, but it's been renamed lq-uitool. It builds in the tools folder and should install automatically if all goes well.
