I want to pin and unpin entries in the dock in 18.04 desktop. I have checked out gsettings and have not found how to do this. Is gsettings even the right tool for this? Any suggestions very welcome.
I have a custom .desktop file: [Desktop Entry] Type=Application Terminal=false Icon[en_US]=/home/alex/bin/idea-IC-173.4127.27/bin/idea.png Name[en_US]=IntelliJ Exec=/home/alex/bin/idea-IC-173.4127.27/bin/idea.sh Name=IntelliJ Icon=/home/alex/bin/idea-IC-173.4127.27/bin/idea.png  Output of ls -lha .local/share/applications/intellij.desktop: -rwx--x--x 1 alex alex 248 Dez 30 10:54 .local/share/applications/intellij.desktop  Answers posted to a previous question () don't work for me. I can find this launcher in Activities and I can double click on that file and IntelliJ will start. Nevertheless, I cannot add this launcher as a favorite to the dock. The option does not show up.

In search of story: Survivor of war game can do no wrong I'm trying to help a teacher friend of mine with finding a short story he read when he was a teenager and has not been able to find since.  He described the story in the following way:  In a post-war world there is a setup in which Soviet/Russian soldiers are required to fight against American soldiers in an arena in which both sides have equal setup: a forest, a lake, etc. The winner of the 'game' has the right to govern for the next several years.  It's told from a first person point of view like you're watching the Olympic games and one American soldier gets shot, but is not killed.  He falls and other bodies fall on top of him so it seems the soviets win, however their last two soldiers happen upon him and he kills them first, rendering the United States victorious.  Given that he was the only survivor he has a sort of political amnesty in which he can do no wrong legally. He returns home and he essentially suffers from a form of PTSD.  The story ends with him watching a young girl next door get off the school bus; he walks to the neighbor's home, goes inside and, in front of the girl's parents follows the girl into her room and shuts the door, leaving the reader to assume whatever happens behind the door.  He's been looking for this story in different anthologies for some time.  Can anyone help?

AttributeError: MapDocObject: Unable to save on mxd.save/saveACopy? I'm trying to use arcpy to save an .mxd and am having an issue.

Check to make sure you have write access to the specified file and that there is enough space on the storage device to hold your document.

What is "my guy syndrome" and how do I handle it?

Why is cd not a program? Is "data" treated as singular or plural in formal contexts? My non-native English speaking friend just asked me: "Data is..." or "Data are..."?  I said both but that's because I've been desensitized from reading/writing both (especially from writing code and adding quick comments).  My question: Is it acceptable to utilize either for a university paper? Or is one safer than the other (when confronted with stickler professors)?

Inner product on $C(\mathbb R)$ With axiom of choice it is possible to construct an inner product on $C(\mathbb R)$. My question is, is it possible to explicitly construct an inner product on $C(\mathbb R)$? I.e. to give a closed formula to calculate the inner product? I know it is straight-forward to write down a scalar product using a Hamel basis. This is not the answer I am looking for. This question came to me, when a student asked me in the lecture today 'whether there are vector spaces without inner products'. So I tried to find scalar produces for function spaces. I think I managed to write one down for $L^1((0,1))$. But I failed to construct one for $C(\mathbb R)$. When to use IMG vs. CSS background-image? In what situations is it more appropriate to use an HTML IMG tag to display an image, as opposed to a CSS background-image, and vice-versa?  Factors may include accessibility, browser support, dynamic content, or any kind of technical limits or usability principles.

When I try to install the App, it tells me it needs at least version 8 of iOS.  I do not want to upgrade my iOS version, especially for the sole purpose of installing an App. However, I do want to use it, it's kind of important.  I searched for a while about how to do this, but I could only find solutions that would work if you installed the App before and it shows up on the "Purchases" page in iTunes or something like that. And this doesn't apply to this case.    How can I install an older version of the App (one that requires "only" iOS 7) without having to upgrade the operating system on my iPhone ?
