Hyperlinks clicked in evince document viewer are not opening, any ideas on how to fix? As it was instructed in another thread here in the forums, I opened the /usr/share/applications/mimeinfo.cache file to check for correct references. And noticed this doesn't seem to be the problem, there even are 3 optional browsers to use.  x-scheme-handler/http=google-chrome.desktop;chromium-browser.desktop;firefox.desktop; x-scheme-handler/https=google-chrome.desktop;chromium-browser.desktop;firefox.desktop;   I already checked that the programs are correctly named, using the "which" command in the terminal, like this:  $ which google-chrome $ /usr/bin/google-chrome   So google-chrome should be the first option and yet the order to open a url doesn't seem to be arriving to the program, not even to the 2nd or 3rd option for that matter anyways.  Also, the 'Get help online...' command in the 'Help' menu doesn't work. So it is not a problem with the specific document file either.  I'm running Ubuntu 12.04 LTS. If you need to ask for more relevant details, please do. It would be nice to have various opinions on how to solve this, thank you :-)  UPDATE: I ran evince from the terminal as asked. This is what I'm getting when trying to open a link:  /opt/google/chrome/google-chrome: line 42: /opt/google/chrome/chrome: Permission denied /opt/google/chrome/google-chrome: line 42: /opt/google/chrome/chrome: Success   Should I try the fix you suggested even if my error log is different?  UPDATE: Tried @maggotbrain's solution and BINGO, now I can study pdf references faster thanks to you bro! Does an unpublished document you upload to ResearchGate count as prior publication when submitting to a journal? On ResearchGate, if you upload something like a thesis, and then it says publish resources, does this mean the thesis becomes properly published in the sense of the usual requirements of journals that there be no prior publication of the submitted work?   I ask because I’m drafting thesis chapters into journal articles and did not choose to publish the thesis as a whole work in order to do so, so I want to make sure that by clicking publish resources I am not actually publishing the copy I’ve uploaded, I’m just making it publicly available? Does this mean it becomes published despite it not technically being a published work? (If so, I’ll just remove the copy I uploaded). There has been some recent behavior change on SE (around July 2015).  I have two accounts I use, one Google openId based for one set of sites (call it Account-A) and another SE login based for a different set of sites (Account-B).  Used to be that I could be logged into one set of sites with the first user and a different set with the other users.    But now I am logged in with the Account-A on Site-1.  When I go to one of the sites I use the other account for and click "log in" under the SE menu, I go to a page where I only have an option to confirm creation of an account based on my Google login.  It does not present a way to log in with an SE account.    How can I log in with my other account here?  (and before you flag this as a duplicate, please ensure the other question is recent enough and that the answer is relevant.  This behavior has definitely morphed over the years... and I am having trouble finding something that is relevant.  For instance this question  simply points out how to merge the accounts which is NOT what I want  .  This question  talks about presenting different user info on each site but that's not what I want -- I want totally separate accounts). I make homemade cayenne pepper sauce every year. I do add some liquid pectin to slightly thicken it so it will stick to food rather than roll off. After a month or so on the shelf it seems to separate a bit. What can I add to this so that it won't or is there a method I can do to stop this. We are slowly working our way into marketing this product down the line and this won't work for that reason. We are using a water bath canning method, vinegar based, no sugar added. For days I tried several ways to install Windows 10 . With Windows Update I have always an error and with the media creation tool microsoft I have this message: " The installation failed in SAFE_OS phase with an error when BOOT operator " with this code : 0xC1900101 - 0x20017 Having tried everything I do not know what to do ... Can you help me please ? Thank you  PS: I migrated my OS with the software "Paragon migrate OS to SSD" from my hard disk to my SSD. Maybe I have this errors because I did this.... proof that every finite matrix has an annihilating polynomial How to create a bootable Ubuntu USB flash drive from terminal? Is there any way to create a bootable Ubuntu USB flash drive from the terminal without using any third-party applications like , , ,  etc.  I tried to create a bootable Ubuntu flash drive with dd method,  sudo umount /dev/sdb sudo dd if=/path/to/ubuntu.iso of=/dev/sdb bs=1M   It creates files on the USB disk, but when I try to boot the USB disk it shows an Operating System Not Found error. Any difference between "Good morning, Brian" and "Good morning to you, Brian" I often hear it on TV when they are talking to a guest.  Normally, if we want to greet Brian in morning, we would say "Good Morning Brian". But many times TV presenters say "Good morning to you Brian".  Why is that? Why do they add "to you". There seems to be no need to do it.  Regards, How vibration sensitive are hard disk drives? I've gotten my hands on a seriously cheap laptop grade 2.5 inch drive. I'm intending to use one on a desktop that doesn't have 2.5 inch bays as a boot drive. While I know there are adapters available, I know its fairly common with SSDs to simply velcro/tape the drive somewhere. I'm wondering if I can do the same with a laptop hard drive.  One issue I see here is SSDs are fairly insensitive to vibration, while hard drives are. Just how vibration sensitive are drives? Would a jerry rigged mount need to take this into account? Open Safari / Google Chrome developer tools programmatically from JavaScript Is there a word that means "a span of six months"? That is, I want to connote a stretch of time that lasts half a year, not an event that happens every six months. Are the foods in the Star Wars Universe the same as ours'? Do they have strawberries or potatoes or something? I know that they might have some food other than the food that we also have, but I'm wondering if they have any food like ours'. Number formation from given digits I was asked this question in a recent interview. You are given two digits $0$ and $9$. Using only these two digits you must form the least positive number that is a multiple of a given '$n$' . The value of $n$ will be provided before hand. For example if we are given $n$ as $7$ then the answer will be $9009$ .  I tried using some basic divisibility principles but was not able to come up with a correct solution and code it up. Probably I need some help in number theory How can I design a tree graph with node shapes as this photo? Execute task if tasker profile has been active for some time How can I execute a tasker task only after a certain condition has been true for a certain time?  Normally a profile executes its task as soon as all conditions are met. I want to delay this activation, until the conditions have stayed true for some time.  E.g.    do something after the screen has been continuously off or on for 10 minutes do something after wifi xy has not been near for 10 minutes do something after cell towers x,y,z have not been near for 10 minutes. Validation Error less than training error? I found two questions  and  about this issue but there is no obvious answer or explanation yet.I enforce the same problem where the validation error is less than training error in my Convolution Neural Network. What does that mean? structs in C with initial values When and where do I have the highest chance of seeing auroras? I'm wondering what time of year is best, and what locations might be best, for catching the aurora.  I'm currently thinking of February up at Sweden's ice hotel, but since the whole point of the trip is so that my wife can see the Aurora, I want to pick a location that affords the best chances to see one.  Edit: Just adding a link so you can see realtime aurora activity in the northern hemisphere    I know this is anecdotal, but I ended up going to Iceland in late february during the new moon and saw the aurora 3 out of 6 nights I was there.  There was activity every single night but the biggest problem was weather.  It was cloudy almost every single night.
