Iris flowers in Yamskaya Steppe

Iris flowers in Yamskaya Steppe

The great thing about places you are already familiar with is that you are always aware of what to photograph once you get there. Nevertheless, these places continue to surprise.
It was like that in Yamskaya Steppe this time. Feather grass hasn′t yet started to flower, while all the primroses were gone, but lots of splendid dwarf iris flowers appeared here and there in the steppe.
Colorless droplets after rain made fresh colors of petals look even better. Iris flowers were just perfect at sunset, sunbathing and shaking slowly after short breeze.

Orchids in a spruce forest

Orchids in a spruce forest

Every creature was glad for such a hot summer weather in the very end of May. Most important, orchids were glad, too! I haven′t photographed them for such a long time, especially not far from St. Petersburg.
So today are some photos of lady′s slipper, Cypripedium calceolus, which likes spruce forests on soils rich in carbonates.
The number of these orchids in that particular location is absolutely incredible! And I′m very happy with that, because our orchids are all endangered and in general very subtle and susceptible to human barbarous approach to nature.

Color profile for Telefunken TV in MPI Guesthouse Golm

Color profile for Telefunken TV in MPI Guesthouse Golm

Telefunken TV screens are very nice but IMO useless facility in MPI Campus Guesthouse in Golm, Potsdam, Germany. Well, unless you connect it to your laptop as a second screen via HDMI or VGA. However, its initial colors are ugly. To make a correction, I have adjusted the screen′s settings to neutral and then calibrated it with X-Rite Colormunki spectrophotometer. The resulting profile is at least usable and quite okay for a TV screen.

Sign Mobileconfig – Apple .mobileconfig configuration profile signing

During installation on iOS/macOS, digitally signed Apple configuration profile is shown with a green tick and corresponding note providing trust for the user. It is possible to use this command in Terminal to sign a .mobileconfig profile. However, it is easier to use a script which will request certificate file, private key and trust chain certificate in dialog.
First, create a new Automator Service named Sign MobileConfig.workflow in user folder
~/Library/Services
Then drag Run AppleScript element into Automator window, and fill it with the following code.
