I've installed Skype by using dkpg and when I try to run it, this is what I get -bash: /usr/bin/skype: No such file or directory. Which is very strange since ls -l | grep skype shows this:  -rwxr-xr-x 1 root   root    30717480 May  7 01:43 skype   I had similiar problems when I installed FireFox, but since I didn't need it all that much, didn't care. However, I do need Skype on Linux.  Output of my $PATH variable:  /home/max/.rvm/gems/ruby-2.0.0-p247/bin:/home/max/.rvm/gems/ruby-2.0.0-p247@global/bin:/home/max/.rvm/rubies/ruby-2.0.0-p247/bin:/home/max/.rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games   Anyone care to explain?... Because I'm stunned.
I have currently a strange problem on debian (wheezy/amd64).  I have created a chroot to install a server (i can't give any more detail about it, sorry). Let's call its path /chr_path/. To make things easy, I have initialized this chroot with a debootstrap (also wheezy/amd64).  All seemed to work well inside the chroot but when I started the installer script of my server I got : zsh: Not found /some_path/perl (the installer includes a perl binary for some reasons)  Naturally, I checked the /some_path/ location and I found the "perl" binary. file in chroot environment returns :  /some_path/perl ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped   The file exists, seems ok, has correct rights. I can use file, ls, vim on it but as soon as I try to execute it - ./perl for example - I get : zsh: Not found ./perl.  This situation is quite understandable for me. Moreover :   I can execute other basic binaries (/bin/ls,...) in the chroot without getting errors I have the same problems for other binaries that came with the project When I try to execute the binary from the main root (/chr_path/some_path/perl), it works. I have tried to put one of the binaries with a copy of my ls. I checked that the access rights were the same but this didn't change anything (one was working, and the other wasn't)
Singular or plural following a list Can anyone tell me if I should use inspire or inspires in this phrase?

No Sound (Dummy Output) error Ubuntu 19.10 Mirrored object not symmetrical I am trying to mirror an object and the original is symmetrical along all axis, but when I attempt to mirror across the y axis, the mirrored side is tilted to a different angle. Number of suggested edits seems to include own edits On the new History beta site I have the privilege to approve tag edits already but my own edits still go into the review queue. And the review dashboard displays a different number of pending edits depending on where I am: on  I see one pending edit, on  I see none. I am pretty sure that the pending edit being displayed is my own - I edited a tag wiki and that edit hasn't been approved yet. It shouldn't be counted no matter where I am. Latest NVIDIA driver on Ubuntu 16.04 Groups with Same Number Of Elements and Subgroups Today I found something strange on my newly installed Windows 7 OS - my "users" folder C:\Users was shared and "Everyone" had full access... I disabled that and now it seems fine, however I'm a bit scared actually, I'd like to know what caused that and if my system is compromised. It is said that we can verify time dilation by flying a very accurate clock on a fast jet or spaceship and prove that it registers less time than the clocks on earth. However, the clocks on earth would be moving relative to the clock on the spaceship, and since time always dilates and never goes faster regardless of the direction of relative motion,  the clocks on earth should register less time than the clock on the spaceship.  Is this true? Whenever there is a fast-moving object such as a rocket do all clocks on earth really become slow?  If the rocket with the clock landed after moving at relativistic speed, would its clock and the earth's clock again show the same time since during its travel both appeared slow to each other?  Or is all this just an illusion, ie. the clocks just appear to be slow to each other but in actually run at normal speed, and neither is behind when the rocket actually lands? How do I center the text horizontally and vertically in a TextView, so that it appears exactly in the middle of the TextView in Android? Is there any way you could revive Guest Sessions in a future LTS distro?  Guest sessions are good security - they give me just enough power to do what I need to do on a daily basis without risking my system. In short, Guest sessions save me from myself.  I had upgraded from 16.04 to 18.04, gotten a problem I couldn't fix and was all to happy to wipe and rebuild my hard drive and return to 16.04.  I can't be the only one who feels this way. How can I download an older version of Xcode? I am trying to download Xcode from the App Store, but it says that I have to have a newer version of macOS. But I don't have enough space on my computer to upgrade. Its like 8 gigs or something like that and if I only could download Xcode that was compatible with macOS Sierra that would be nice. RedirectMatch and Query String Compare these two RedirectMatch's. The first doesn't work: RedirectMatch 302 ^/redirect\.php[?]page=(.+)$ http://somewhereelse.com/$1  Versus this, which will redirect to http://somewhereelse.com/?page=wherever: RedirectMatch 302 ^/redirect\.php([?]page=.+)?$ http://somewhereelse.com/$1  Does RedirectMatch only match the URI and not the query string? Apache's documentation is a bit vague in this area. What I'm trying to do is extract the page query parameter and redirect to another site using it. Is that possible with RedirectMatch or do I have to use RewriteCond + RewriteRule? I recall in at least two episodes of Star Trek ( from the original series and  from The Next Generation) that there is reference to and contact with species from external galaxies.  By the 29th century, we see that timeships exist.  My question is, is there any reference to intergalactic relations in Star Trek in the future (say, by the 29th Century), or does the Star Trek Universe stay in the Milky Way Galaxy? How to add indicator on a light switch to indicate the outdoor 3-way light is on? Have some carriage lights outside my garage that can be turned on from inside the house. It's common that the switch will get flipped and the lights will stay on when they're not wanted.  Is there some way I can add an indicator to the light switch so I can know if the light is on?  Note: the carriage lights are on a 3 way switch. I have an odd error that I have been unable to find anything on this. I wanted to change the user comment with the following command.  $ sudo usermod -c "New Comment" user   This will work while logged onto a server but I want to automate it across 20+ servers. Usually I am able to use a list and loop through the servers and run a command but in this case I get a error.  $ for i in `cat servlist` ; do echo $i ; ssh $i sudo usermod -c "New Comment" user ; done  serv1 Usage: usermod [options] LOGIN  Options: lists usermod options  serv2 Usage: usermod [options] LOGIN  Options: lists usermod options . . .   When I run this loop it throws back an error like I am using the command incorrectly but it will run just fine on a single server.  Looking through the ssh man pages I did try -t and -t -t flags but those did not work.  I have successfully used perl -p -i -e within a similar loop to edit files.  Does anyone know a reason I am unable to loop this? Straighten Vertices Along a Line On a line, I need to line up the bottom vertex points in relation to a top reference vertex point. How could I reset the X Y and Z coordinates of these vertex points to essentially line them up all through use of the vector of the reference point vertex.  I do not have access to Mesh -> Transform -> Scale on Axis for aligning vertices along a line. Etymology of "dong" and "dongle" Dong as in ding-dong is clearly onomatopoetic as confirmed by :     ding dong        imitative of the sound of a bell, c.1560.   and similarly for :     ding (v.)       1819, "to sound as metal when struck," possibly abstracted from ding-dong, of imitative origin. The meaning "to deal heavy blows" is c.1300, probably from Old Norse dengja "to hammer," perhaps also imitative. Meaning "dent" is 1960s. Related: Dinged; dinging.   What, then, is the origin of dong to mean penis? Etymonline.com is  here:     dong (n.)        "penis," 1891, of unknown origin.   We also have a much more recent word, dongle, which has no entry at etymonline.com but  claims it is:     Apparently from dangle.   This leads me to the theory that the anatomical and onomatopoetic dongs  are not related and that the former usage, like dongle, derives from dangle. So, my questions are:   Is that so? Does dong (penis) derive from dangle? Sounds reasonable enough but I have found no definitive sources for it. Does dongle derive from dangle? It makes perfect descriptive sense for dong but the USB devices called dongles do not dangle but instead protrude quite rigidly, so I feel that dongle being derived from the cruder meaning of dong makes more sense. $n$-th digit in the sequence of natural numbers Pixelated image in ps format!
