ColorHUG, an inexpensive open source colorimeter, is a great little tool for calibrating a display and generating an ICC profile for it. But if you migrated to the latest version of Kubuntu featuring KDE Plasma 5, you might wonder how to install the existing ICC profile for your display. The easiest and quickest way to do that is to use the dispcalGUI application. You can install dispcalGUI using the Muon software center, or by running the sudo apt-get install dispcalgui command in the Konsole.
Once dispcalGUI has been installed, launch the application, press the Load Settings button next to the Settings drop-down list, and select the .icc file. Use then the Install Profile button to install the selected profile either globally or for the current user only. That’s all there is to it.
Mervyn O’Gorman was an English engineer whose artistic interests turned him into one of the early pioneers of color photography. Using the Autochrome Lumière process that was launched in 1907, O’Gorman shot images that are now regularly featured in exhibitions of early color photos.
Among his best known works are a series of color photos of his daughter, Christina, taken in 1913.

Geofix is a simple Python script that lets you use an Android device to record the geographical coordinates of your current position. The clever part is that the script stores the obtained latitude and longitude values in the digiKam-compatible format, so you can copy the saved coordinates and use them to geotag photos in digiKam’s Geo-location module.
To deploy Geofix on your Android device, install the SL4A and PythonForAndroid APK packages from the Scripting Layer for Android website. Copy then the geofix.py script to the sl4a/scripts directory on the internal storage of your Android device. Open the SL4A app, and launch the script. For faster access, you can add to the homescreen an SL4A widget that links to the script.
Instead of using SL4A and Python for Android, which are all but abandoned by Google, you can opt for QPython. In this case, you need to use the geofix-qpython.py script. Copy it to the com.hipipal.qpyplus/scripts directory, and use the QPython app to launch the script.
Both scripts save obtained data in the geofix.tsv tab-separated file and the geofix.sqlite database. You can use a spreadsheet application like LibreOffice Calc to open the former, or you can run the supplied web app to display data from the geofix.sqlite database in the browser. To do this, run the main.py script in the geofix-web directory by issuing the ./main.py command in the Terminal.
To geotag photos in digiKam using the data from Geofix, copy the desired coordinates in the digiKam format (e.g., geo:56.1831455,10.1182492). Select the photos you want to geotag and choose Image → Geo-location. Select the photos, right-click on the selection, and choose Paste coordinates.
Nowadays when we order takeout we open an app, push a few buttons and 30 minutes later someone shows up on a motorcycle with your food. But in the olden days in Japan it was obviously a bit different. Demae, which literally means “to go in front of” is thought to have originated as early as the mid-Edo period in the 1700s.
