How can I set the default terminal emulator? Preferably from the command line.  I am running Ubuntu 14.04.03, and Unity and Lubuntu desktops
How can I set the default terminal used in Unity?  I would like to use the Ctrl+Alt+T hotkey to start a non-default terminal. The default terminal is gnome-terminal.   Where can I change the default terminal value?
How to disable USB storage device support I want to disable a particular USB storage device (a sandisk flash drive). I read somewhere that you can use the .config file. How do i use it to disable that? Show the Dihedral Group $D_n$ is generated by rotations and reflection along the x axis.

Cold fusion is being mentioned a lot lately because of some new setup that apparently works. This is an unverified claim.  See for example:         ( of that last link in the Wayback Machine, given frequent  from that page.)   While we should give the scientific community time to evaluate the set up and eventually replicate the results, there is undoubtedly some skepticism that cold fusion would work at all, because the claim is quite extraordinary.  In the past, after Fleischmann and Pons announced their cold fusion results, in perfectly good faith, they were proven wrong by subsequent experiments.  What are the experimental realities that make Fleischmann and Pons style cold fusions experiments easy to get wrong?  Would the same risks apply to this new set up? I try to search for lines that start with "1" using   ls -1 | grep ^1*   but it returns lines that do not start with 1. What I am missing here? Does decrease in temperature affect mass $E=mc^2$? My understanding of Quantum physics and String Theory is very basic and I don't yet have a grasp on the maths, but in my research I have come up with a question.  Does a decrease in temperature also signify/create a decrease in mass?  I am quite willing to believe the concepts I think I am beginning to understand are totally misconceptions on my part.  But, as I see it mass is a product/mark of disruption to the Higgs field as a particle moves.  If these particles are ultimately composed of vibrating Strings, their mass is given by the rate at which they vibrate and how it interacts with the Higgs field.  I don't have any idea if, as the temperature (as we know it) approaches 0k, the string/quark/sparticle would change its state in any way or if the changing of the state of the String would change what type of particle it represents.  It seems I'm more full of questions than answers, but that's why I love these topics!  I know what I'm learning is new if the best and brightest are still working on the 'basics' to just make their systems work :). Wasted screen space due to multiple horizontal bars at the top when an application is open in GNOME desktop Short story about survivors on Earth after the atmosphere has frozen This is a short story I read maybe in the '80s.  Earth has been thrown away from the Sun, probably due to a very large object passing through the Solar System, and the atmosphere has frozen in layers. There is a small family - father, mother, two children, who live in a room they have made airtight by hanging many layers of material to slow the loss of air. They keep warm with a 'camp-fire'. The father goes out every day in a suit of some sort to find food and mine frozen oxygen. It ends when they are found by another, larger group of survivors.  Does anybody know the title and author? android expandablelistview how to set space between groups items Past Subjunctive vs Future Subjunctive form How do I get started with 'painting with light' photography? Tunnels being naturally dark may not be the most intuitive choice for a place to take pictures. But I love the '' work that artists such as '' are putting out and they're clearly seeking out places like tunnels, caves, garages... Dark places in other words, to create their works of art. Which brings two questions to mind:   How do I go about finding places that I can accomplish this sort of 'tunnel photography.' What are some techniques that I can use to 'paint with light' in my photography once I have found some locations? Does the Black Panther suit give extra speed? So in Civil War, the Black Panther suit seems to give the suit holder some extra speed, because the guy was running as fast as Bucky and Captain America.  So does it give extra speed? If so, how does that work? How do I deliver a baby? I'm playing Fallout Shelter, and my newest bonus objective is to "Deliver 1 Baby Dweller."  I've already figured out that I can put a male vault dweller and a female vault dweller together in some residential quarters, and and eventually, if they hit it off, the lady will replace her vault suit with a yellow sweater and a decidedly pregnant figure.   Good enough.  But how long does it take her to deliver the child? Do I have to induce it through some sort of tapping ritual or placing her in the correct room? Does the pregnant dweller need to stay in the living quarters, or can I put her to work in my Diner or Water Treatment Facility? Do the SPECIAL stars of the parents matter?  Tell me everything about  and what I can do to control the process. I am using the below script to move two days back when script runs at starting two days of the year and also check first and second days of every month and move two days back. if [$month=&quot;01&quot;] &amp;&amp; [$day=&quot;01&quot;]; then         date=&quot;$last_month/$yes_day/$last_year&quot;         fulldate=&quot;$last_month/$yes_day/$last_year&quot; else         if [$month=&quot;01&quot;] &amp;&amp; [$day=&quot;02&quot;]; then                 date=&quot;$last_month/$yes_day/$last_year&quot;                 fulldate=&quot;$last_month/$yes_day/$last_year&quot;         else                 if [ $day = &quot;01&quot; ]; then                         date=&quot;$last_month/$yes_day/$year&quot;                         fulldate=&quot;$year$last_month$yes_day&quot;                 else                         if [ $day = &quot;02&quot; ]; then                                 date=&quot;$last_month/$yes_day/$year&quot;                                 fulldate=&quot;$year$last_month$yes_day&quot;                         else                                 date=&quot;$month/$yes_day/$year&quot;                                 fulldate=&quot;$year$month$yes_day&quot;                         fi                 fi         fi fi  But my bad am getting the below error message Etime_script.sh: line 19: [06=01]: command not found Etime_script.sh: line 24: [06=01]: command not found Who should own files shared by a group and where should they go For realism should I use the maximum number of Subsurf levels? I was wondering if I always need to use the maximum value of the options from the elements of "Add Modifier". For example, do I need to use the view 6 in Subdivision surface? I know it depends of what we are trying to achieve, but we all want the same. Make something look the most believable. So do you always use the maximum value Blender offers? Why are you not able to declare a class as static in Java? Hi Blender coders and artists.  I am updating one of my add-ons for Blender 2.8 and have run into some  issues finding the appropriate way to hide a collection that is added to my scene.  I want to deselect the eyeball on the toolbar with a python command in a script but I don't want to disable the collection in the view-port entirely as it is used as a collection in a particle system.   I just want to deselect the eyeball circled in green below.  Anyone know the python API for this?
