xpanta's questions

I am using ubuntu 16.04 and have installed python2 and python3. Default is python2.

I am trying to install a python module (mapscript) with this command

sudo apt-get install python-mapscript

because for some unknown reason I cannot use pip to install it (either in or outside of a virtual environment).

using apt-get the module is succesfully installed in /usr/lib/python2.7/dist-packages/ but not in python3/dist-packages.

In my project I use python3.

Is there any way to apt-get install a python module for python3 explicitly? Module is supposedly compatible with python3.

I have postgreSQL 9.1 installed in my system. I want to run pgbench but the program is not istalled. I tried these but failed:

apt-get install postgresql91-contrib

no packet found

apt-get install postgresql-contrib

no packet found

ln -s usr/share/postgresql-common/pg_wrapper /usr/bin/pgbench

made the symlink but I get this error:

Error: pg_wrapper: invalid command name

What am I doing wrong?

I have purchased a mirrorless Samsung NX300 which is a nice entry-leve mirrorless camera. However Samsung produces a stupid proprietary RAW format instead of the standard RAW format (do other vendors do this?). And instead of RAW files I get .SRW files. Ubuntu recognizes them as TIFF but nautilus does not show thumbnails and image viewer does not show them. I can open them using Rawtherapee or Darktable and that is more than fine.

However, I was wandering if there is a quick and dirty way to mass convert all SRW files to TIFF files (or any other lossless standard).

I have installed an ethernet connected Epson Stylus BX525DW printer. I can print in colours and I can scan documents. Installation was automatic. It took me 10 seconds. However I can't print in black.

Note that the inks are not the original. I bought inks from ebay. However, the same printer was printing in black in windows before. Although black is almost grey (inks are of terrible quality, that is a fact).

These are my CUPS settings:

Can I fix this?

(I am using Ubuntu 12.10)

I have added .thunderbird folder to my Ubuntu One's folders to be synced. This is to protect my mails and my thunderbird's settings and plugins.

However, U1 constantly keeps messing up with my folders and a lot of .u1conflict files appear in various places in my .thunderbird folder. Some of them I see on my thunderbird application when I start it up.

Why is that? Can't I just select my home folders files to be uploaded and not synced? Or set U1, in case of conflicts, to leave the home folder structure and files as is.

PS: I have subscribed to U1 service and this is important to me.

I am trying to backup my home folder on my NAS drive. I am giving this:

rsync -Paz --exclude-from 'rsync-exclude.txt' /home/chris/ [email protected]:LinuxHome

where rsync-exclude.txt has this content:

/home/chris/Downloads/*
/home/chris/Downloads/
/home/chris/Downloads/*.*

and it is in the same folder I execute rsync (home folder).

However the rsync tries to copy this folder, too.

When I do import numpy on my shell, numpy is found (I can use it). However, when I workon my virtualenv import numpy gives me no module named numpy error.

I tried to pip install numpy while working on my virtualenv but I get a could not create '/usr/lib/python2.7/site-packages' error. I tried with sudo and it says that Requirement already satisfied.

Why?

I have installed, already, ubuntu (latest) on SSD OCZ Vertex 4 (everything, home, tmp, /, swap, etc).

I have two other HDDs. One is just Windows (used by my wife, only) and one is used to just store big media files (300GB each).

Someone told me that swap and tmp files will wear out my SSD. Is this true?

Having this installation, what should I do now, in order to protect my SSD?

I have been assigned a task that seems to be really hard for me.

I want to convert a video taken with iPhone4 (.mov) to a format that can be understood by Powerpoint (.wmv?)

I tried avidemux, but I don't know which is the correct format I must save the rotated file to.

I am using ubuntu 12.10

I have a Western Digital connected to my router at 192.168.1.65 statically.

How can I automatically connect at login and rsync? At the moment I am using this command that doesn't work.

rsync -Paz /home/chris/ 192.168.1.65:LinuxHome/

but I get this

ssh: connect to host 192.168.1.65 port 22: Connection refused rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: unexplained error (code 255) at io.c(605) [sender=3.0.9]

This screenshot of the Western Digital MyBookWorld control panel might help

EDIT: I updated the command to rsync -Paz -e ssh /home/chris/ 192.168.1.65:LinuxHome/ as suggested and it works (I also enabled ssh from the control panel) but I would like to connect-rsync automatically (either by a cron job or during login no matter to me)

After the latest update, Rhythmbox (which was my main mp3 player on my Ubuntu Latest distro) stopped functioning: it dies just after startup. So, I turned to Clementine which I like a lot. However in Rhythmbox I had my playlists and ratings. Song ratings are very important to me because many of my auto-playlists are depending on them.

Is there anyway I can get my playlists and ratings from Rhythmbox and add them to Clementine?

Thanks.

I am thinking of upgrading my old ATI/AMD Radeon 4870 to nVidia (610 or 620, maybe 630). I am not playing games. I like Compiz effects though. I use ubuntu 12.10.

Anyway, I would like to ask how to do it properly. I think I have to remove proprietary drivers first (ATI Legacy 12.06), restart and install nVidia proprietary drivers, then.

This is what I did in order to install my ATI drivers:

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy

PS: Any advice on a good but inexpensive nVidia card would be greatly appreciated, too.

PS2: Wiil I need to upgrade my xorg?
