Location of local configuration files for Filebot on Linux

Silly me, I assumed Filebot would store its local settings to the $HOME/.config/filebot folder, or at least the $HOME/.filebot folders that it created. But they were not there, and after setting up my new OS I wanted to restore my file rename patterns. Fortunately I kept copies of those patterns in my Evernote account, but I was still curious where the configuration files were. After some searching I dug up the location.

$HOME/.java/.userPrefs/net/filebot/ui/

Asus N550JV scanning with the Brother DCP-7030 under Linux

I got a new laptop, the Asus N550JV. I'm installing Arch Linux on it, as I've been an avid Arch user for several years now. I'm still using my old Brother DCP-7030 printer/scanner combo unit and although the printer works fine, I was unable to scan. After hours of troubleshooting and google-fu, I finally narrowed the problem down to an incompatibility with the Sane library and USB 3.0 interfaces on linux. The scanner works fine under Windows 8.1 (of course), but every time I tried to scan under Linux I got the following error:

scanimage: sane_start: Invalid argument

After finding a similar problem with a different software package (Ardour), I went into the BIOS and set the XHCI Pre-Boot Mode to disabled and my scanner started working again.

I'm not sure yet if this is a Sane issue, or just related to my printer/scanner and it's old Linux drivers. When I upgrade my printer/scanner later this year I guess we'll find out.

Using Ibus with Skype on 64-bit Arch Linux

Adding the following lines to my /etc/environment file, along with installing ibus-qt and running qtconfig to set the default input method, allows Skype and Ibus to work together on my Arch 64-bit system running Gnome 3.2..

LANG="en_US.UTF-8" 
LC_ALL="en_US.UTF-8" 
GTK_IM_MODULE=ibus 
XMODIFIERS=@im=ibus

Landscape printing in LibreOffice

LibreOffice insisted on printing everything in Portrait orientation, no matter how I configured the document or the printer. I discovered the following setting on the Arch Linux forums that fixed the problem.

Set File -> Printer Settings -> Properties -> Device -> Printer Language type to PostScript and create new default templates so the settings stick.

Installing the Brother DCP-7030 in Arch Linux

Running Arch Linux I had to create the following udev rule in
/etc/udev/rules.d/10-cups-usb.rules
in order for the printer to be recognized.


ATTR{idVendor}=="04f9", ATTR{idProduct}=="01ea", MODE:="0664", GROUP:="lp", ENV{libsane_matched}:="yes"


Then I was able to use the driver in the AUR to install it in CUPS.

This entry in the Arch Forum helped me figure it out.

Install Ruby 1.8.7-p352 on Arch Linux

I'm returning to Arch Linux for my trusty laptop. After installing RVM and all of the requirements listed in the notes page, I would get compilation errors when trying to install ruby 1.8.7-p352.


callback.func:78:33: error: expected ')' before '(' token
callback.func:79:3: warning: data definition has no type or storage class [enabled by default]

callback.func:79:45: error: 'argv' undeclared here (not in a function)
callback.func:82:1: error: expected identifier or '(' before '}' token


I was able to find a patch in the AUR version of ruby that fixed the problem.
