Anaconda desktop entry for Ubuntu 18
Check if anaconda3 is installed on your system or not (Sometime the package may be broken due to network issues during installation (Not worked for me)). And whether you are able to launch anaconda-navigator without a desktop entry. Try this. If it works, you're definitely all set to go. $ anaconda-navigator & Open your text editor and save the following content as Anaconda.desktop to your home directory. [Desktop Entry] Version=1.0 Type=Application Name=Anaconda-Navigator GenericName=Anaconda Comment=Scientific Python Development Environment - Python3 Exec=bash -c 'export PATH="/home/munim/anaconda3/bin:$PATH" && /home/munim/anaconda3/bin/anaconda-navigator' Categories=Development;Science;IDE;Qt;Education; Icon=/home/munim/anaconda3/lib/python3.7/site-packages/anaconda_navigator/static/images/anaconda-icon-256x256.png Terminal=false StartupNotify=true MimeType=text/x-python; Change munim to your username in Exec and Icon lines. Also change python3.7 to something else if you're not on Python 3.7. $ sudo cp Anaconda.desktop /usr/share/applications This will create a desktop entry named Anaconda in /usr/share/applications/. |
Bird Quotations
 It sings because it has a song.”
Chinese Proverb ”Everyone wants to understand painting. Why isn’t there any attempt to understand bird songs?” Pablo Picasso (1881-1973) ”Use what talents you possess: the woods would be very silent if no birds sang there,
except those that sang best.” Henry Van Dyke (18521933) ”Fall is my favorite season in Los Angeles, watching the birds change color and fall from the trees.” David Letterman (1947 - ) ”God loved the birds and invented trees. Man loved the birds and invented cages.” Jacques Deval (1895-1972) ”A light broke in upon my soul – It was the carol of a bird; It ceased – and then it came again The sweetest song ear ever heard.” Lord Byron (1788-1824) ”It is not only fine feathers that make fine birds.” Aesop (620 BC - 560 BC) |
