How can I bind the meta key (a.k.a.  / Windows key) to a left click? Hitting the meta key should trigger a left click, and pressing down on it should allow me to drag and drop (just like it would do when holding down left click).  I tried using System Preferences -> Shortcuts and Gestures:    but I cannot set "meta" alone as being a shortcut.  I use Kubuntu 14.10 Plasma 4.   (On Windows 7 SP1 x64 Ultimate I can achieve that using the program .)

I wanted to switch to Xfce (I had KDE and GNOME installed), and I did this :    sudo apt-get install xubuntu-desktop sudo apt-get remove kubuntu-desktop sudo apt-get remove ubuntu-desktop sudo apt-get autoremove   but to my surprise, I could still pick gnome, kde plasma, etc during the log in.  So, how do I completely remove KDE and GNOME desktops? On the nature of the collapse of the wave function The collapse of the wave function by measurements is one of the most mysterious properties of quantum mechanics.    At what scale does the wave function collapse? What are the conditions for a collapse?  Can it be made precise?  Does the collapse happen instantaneously, or is it spread out in time?  What is the precise equation for the collapse?  Why is the collapse time-asymmetric, and can this explain the arrow of time? In a technical environment, what is the most suitable sentence to use when answering to someone about a problem that they had and we solved it for them:   The problem is solved The problem has been solved How can I get vertex positions from a mesh? I want to read the vertex x and y coordinates with a script or a function.  How can I do that?  The   appears to have no position I could use.  I'd take any alternative approach that could give me x and y coordinates. Missing argument 2 for wpdb::prepare() Issue I'm having to update a WP installation for a community organisations from version 2.9.1 to the current 3.9.1.   The installation has a couple of custom built plugins that aren't documented.  I've just performed the WP version update and now I see a warning (Missing argument 2 for wpdb::prepare()) on every page that relates to the following line in the code of one of these custom built plugin:  $rows = $wpdb-&gt;get_results($wpdb-&gt;prepare("SELECT id, name FROM ".$table_name));   From what I've read online, this is due to a change in the coding, that requires 2 values to be sent to wpdb::prepare(), but I've no idea how the line of code given above, needs to be changed.  If someone could help me out, I'd really appreciate it. I understand that they force you to implement methods and such but what I cant understand is why you would want to use them. Can anybody give me a good example or explanation on why I would want to implement this. Why does replication require primers while transcription does not? I've been trying to ignore my burning desire to make some guacamole because every time I go to the supermarket to buy avocados I can't manage to pick out good ones.  They always either become too soft before I have a chance to do anything with them or are hard and not very tasty.  How can I tell when an avocado is perfectly ripe? Does text in brackets invoke the "an" vs. "a" rule? External hard drive very slow to load after dropping it and can't be repaired with Disk Utility Today as I was using my WD HDD, it fell off my corner. After I fixed the thing, I plugged it into the Mac and it loads the HDD but it's very very very very slow. It also does not work sometimes. The entire laptop just hangs  Tried running Disk Utility First Aid but it won't work.  It says some error and hangs  Can someone advise me on what I can do in this case? What is covered by CDIC savings deposit insurance? How can I securely erase a hard drive? I'm planning on selling a USB external hard drive that currently contains an old Ubuntu installation with stored passwords and banking information.  How can I securely erase the drive before selling it? Can't use Shortcut key on linux mint 19 XFCE The shellscript is very simple:  retroarch $* -c /tmp/retroarch/Data/retroarch/gambatte.cfg   ("retroarch" is another shellscript)  If the filename passed contains spaces it fails:  RetroArch [ERROR] :: Could not read ROM file. How to cleanly launch a GUI app via the Terminal? Some GUI apps launch cleanly via the Terminal command line, but some don't, and they cause the Terminal to wait for the app to terminate. Even then, some don't "release" the command line.  The mysterious ampersand &amp; suffix seems to cause the terminal to put the process into the background (but I'm not sure what happens there).  Is there a way to launch an app via the Terminal so that there is no "hang on" effect, just like launching something via Alt+F2?  I'd like to have the command line available again immediately, without something still in the background and printing in the terminal. Why can't I use Stack Exchange if I'm under 13 years old, or if I'm under 16 years old and from the EU? Heres a picture. im making a body, and it seems to have flash in the middle. Standard formula for quick calculation of scores I have three datasets as follows:   Dataset A can have a maximum score of 30. (Individual scores can be from 1 to 30) Dataset B can have a maximum score of 45. (Individual scores can be from 1 to 45) Dataset C can have a maximum score of 25. (Individual scores can be from 1 to 25)   The three datasets contribute equally to a final score, hence it is 33.33% each. i.e. (33.33% for dataset A + 33.33% for dataset B + 33.33% for dataset C) = 100% (final score)  I have the following scores in each dataset:   Dataset A: 22 Dataset B: 15 Dataset C: 10   Is there a quick formula that I can use to work out the final score, based on the above datapoints?   (This is not a homework question.) Missing dollar problem This sounds silly but I saw this and I couldn't figure it out so I thought you could help. The below is what I saw.  You see a top you want to buy for $\$97$, but you don't have any money so you borrow $\$50$ from your mom and $\$50$ from your dad.  You buy the top and have $\$3$ change, you give your mom $\$1$,your dad $\$1$, and keep $\$1$ for yourself.  You now owe your mom $\$49$ and your dad $\$49$.  $\$49 + \$49 = \$98$ and you kept $\$1$.   Where is the missing $\$1$? MySQL is giving weird result
