So you don't have to reinvent the wheel.
Useful Firefox settings. Change them in about:config
| security.dialog_enable_delay | The delay in ms before you can click the "install plugin" button. |
| dom.max_script_run_time | Maximum script runtime in seconds before Firefox asks if you want to terminate the script. |

Loading...On my CUPS server, I've connected a Dymo 400 labelwriter. For some reason, while printing labels perfectly, I just can't get the imagetoraster filter to stop "crashing" with the following error:
ERROR: Unable to write raster data to driver!
So I fixed this the dirty way. I downloaded the CUPS Source RPM from CentOS. I installed it to /usr/src/redhat using the command rpm -i cups-1.4.2-35.el6.src.rpm. In the directory SOURCES, I added a file named geeklab.patch containing:
--- cups-1.4.2/filter/imagetoraster.c 2009-06-05 23:38:52.000000000 +0200

Then I added to the spec:
Patch700: geeklab.patch
after the line that starts with Patch100:
and %patch700 -p1 -b .geeklab just after the line that starts with %patch100
Now you can use the regular rpmbuild commands to build packages:
rpmbuild -bs <specname> to build a new SRPM
rpmbuild -ba <specname> to build a new SRPM and binary RPMs
I personally prefer the first, as I mostly use mock to build clean destination RPMs.

[2011/12/08 10:18:26.821280, 0] printing/print_cups.c:108(cups_connect)
Unable to connect to CUPS server localhost:631 - Connection refused
I don't want Samba to offer printers. After trying some configurations, I found this made smbd stop trying:
load printers = no printing = bsd printcap name = /dev/null |

The correct combination for linux-in-vmware-on-linux is CTRL+ALT+SPACE, release space while holding down CTRL+ALT, then add the F1 key.

Just before the line exec $MOZ_PROGRAM "$@" add one more line:
export LC_TIME=nl_NL
(or any other language of your choice)
There are probably other/easier ways to do this, but since I want this to only affect thunderbird, I prefer this method.
