Linux – text editing

Text editing is a basic thing:
bash, perl, PHP, HTML, Python or any other programming is done in a text editor.

Most if not all configuring of Linux can be done using a text editor

A well working and feature rich editor is a must.
If it has free and open source, then that is a plus.


Digital Photos on Linux

A seized blog (last post April 11, 2008) that seems to hold some still useful information… I need to dig more!
It is here:

More recent:


Direct links:
– prevoius “Bibble”
  – Shotwell – Fotoxx

Color management:
Argyll CMS – basis for Ubuntu’s built in features, used by “gnome-color-management”
Oryanos and KCM

Hardware choice:
X-rite Colormunki – select the right version and you will calibrate all of your devices.
Datacolor’s “Spyder” tools are yet to be equally versatile, printer calibration lacks – and what is present requires Windows.

At present I’m running nvidia’s GTX 780 and a wide gamut monitor – in a multi-display setup, and found it very well working, still “need” to install their proprietary driver to be up to date – and there seem to be small issues with color profiles not being activated properly as it starts (a few clicks required each boot, for all but the initial display). Edit: look up the xorg-edgers ppa instead, updates no longer cause trouble.

Edit 2014-07-03: These are for nvidia drivers anv virtualbox, and better make sure they’re NOT on the last line – note “DUMMY”, this is the tool to have other things stay away from the last line. Finding out this was a tad of a chore, the issue with color profiles was caused by the nvidia-persistenced group being on the last line. I noticed it started working when I added virtualbox, but as *that* ended up on the last line USB was impossible to get working… With “DUMMY” (below) I have both working.

$ tail -n 4 /etc/group



Any shortcomings may be covered by running e.g. Oracle Virtualbox (Virtual machine) with a suitable Windows version installed: – Oracle VM VirtualBox

Current version is 4.3.12 – installing it on Ubuntu 14.04 LTS:
Edit 2014-07-03: Note, 4.3.12 is required for having shared clipboard actually work!

At the $ prompt of a bash shell (Terminal) type:

cat >
if ! grep -i virtualbox  /etc/apt/sources.list ;then
  sudo echo -e >/etc/apt/sources.list \
    "\n## oracle virtualbox\n" \
    "deb trusty contrib\n"
  echo "Virtualbox added into apt - sources.list"
  echo "Virtualbox present in apt - sources.list"

echo "$(tput smso)--- Oracle public key for apt-secure ---$(tput rmso)"
wget -q -O- | sudo apt-key add -
echo "$(tput smso)--- apt-get update ---$(tput rmso)"
sudo apt-get update
echo "$(tput smso)--- apt-get install VB+dkms ---$(tput rmso)"
sudo apt-get install virtualbox-4.3 && sudo apt-get install dkms

Press CTRL-D, and hit Enter

Then run it to actualy do the installation, with:

$ source

… the first “sudo” execution will ask for your password (to switch to super-user privileges)

To start, type “virtualbox &”  in the shell, or look up virtualbox with Dash app lens (Super +A) and drag the icon anywhere you wish (to have it visible next time) before you just click on it.

On Ubuntu Linux, a 16bit+ GIMP

NOTE: This is GIMP 2.9, as always odd-numbered versions are potentially unstable.


The source of this: is here

Open a terminal (CTRL-Alt+T), i.e. bash prompt, then type:

sudo add-apt-repository ppa:otto-kesselgulasch/gimp-edge
sudo apt-get update
sudo apt-get install gimp
sudo apt-get install gimp-resynthesizer


Time to upgrade…

This requires a bit of scripting, I’d prefer Linux / bash as it is right now, but there might be other ways.
Might be it could be done with a BAT-script for Windows users will provide you with a lot of options, but it might a bit daunting – throwing you into a very Linux’y world.

Beyond the controlling environment, you need a copy of “wget” or possibly “curl” – both command line tools from the Linux world.

These will both grab the response on a URL “GET”, into a file if you say so (default is “print it”).
ULR: simple text – the very same you type in the address field of your browser.

You need these:
will create a list of ALL photo ID’s among other things, when given ONLY the user ID.
will give you the info about one of the photos, based on the ID.

Oh, you need to read the “Read these first:” texts to get somewhere at all.

… ^– that is all the basic info you need. Now the remainder is a bit of scripting.

Linux, an easy start?
