Whenever I try to delete a field associated to a content type, I get the following error:     Drupal\Core\Field\FieldException: Attempt to create a field   field_cert_fields that does not exist on entity type node. in   Drupal\field\Entity\FieldConfig->getFieldStorageDefinition() (line 286   of core/modules/field/src/Entity/FieldConfig.php).   the field field_cert_field is not actually there in any of the content types.   How can i resolve this problem? Even if am getting this error, the field I wanted to delete is deleted.  UPDATE    I have a custom module that defines a custom field in  /modules/certfield/src/Plugin/Field folder .I cant uninstall the module and it says :     The following reason prevents SSl Cert Field from being uninstalled:   Fields pending deletion   once i removed the module manually when it cant uninstall via drush .  I guess that makes the issue . Anyway to get rid of this ?
I'm stuck with an uninstallable module. Drupal insists that there are Fields pending deletion and that the module can not be uninstalled. I've run cron zillion times already as advised for such situations but without success. Cron runs fine, but drupal insists that still, Fields pending deletion.  Visiting /admin/reports/fields gives no clues - the fields provided by that module are not listed. I even tried using drupal console to uninstall module with --force switch, but also without success.  I also tried drush field-info in hope to get some clues, but that's apparently not yet implemented as drush 8.1.2 gives fatal error:     Call to undefined function field_info_fields().   How do I make drupal delete those fields that pending deletion? Do I have to do this manually in database?  I've seen few tables like field_deleted_data_f5e7b87e32 or field_deleted_revision_be01eddd10 but they are all empty. Is that even relevant?
Including pdf_tex images from inkscape I work behind an really annoying firewall, and I just want the net admin to add all the SE websites to the whitelist. Right now I've lost access to Stack Overflow's authentication, but not Meta's... so I have to come here before I log in there.  It's driving me nuts. Basically I just want to add an exclusion rule for all SE domains; not only the website domains, but also the content domains such as gravatar.com, quantserve.com, the domain that holds static content, etc...

In Star Trek it is frequently seen that when a crew member wants to avoid being tracked, they'll leave their communicator somewhere (quarters, corridor etc) which throws the computer and ship's security off their trail.  However, the entire interior of the ship is under constant surveillance by the internal sensors. Barring damage to the ship or sensors, or some space phenomenon causing radiation X to create interference, why aren't these internal sensors able to continue tracking every person on board regardless of where their comm-badge is? In the worst case, they should be able deduce who the errant individual is by simple subtraction: "I can see where all the other comm-badges are, so subtract them and the remaining life form must be the person I am looking for." But this never seems to be done either.  Is Star Fleet security really so inept or is there some other limitation in play that is never mentioned? In many languages, including English, the most important verbs are irregular. Examples include:   to be  to do  to get  to go  to have  to make   The same applies (roughly) to many other languages I know about (Dutch, German, French, Spanish, Swedish) and presumably to many other languages too.  Is there any reason why these everyday verbs tend to be irregular? How to place a .png texture with transparency over a material I am trying to create a low poly face with a face from a .png file. The issue is I already have material placed for hair and skin, as shown in the picture below.   I have created a .png file with a face which I would like to overlay over the skin material on the front of the head.    All examples I searched so far assume I also want the color of the material from the .png texture.  Update:  I added UVMapping, changed view to texture, made sure one face is on the eye but nothing is displayed..... see image... I don't know what is going on. Got a bunch of .mp4 videos (info shows H.264 Video + AAC Audio) that are chapters of a larger video.  I'd like to merge them, but not sure which is the best way.  I don't have Quicktime Pro, but I'll get it if that's the best way to do this.  Edit: Just to clariify this is Mac OSX 10.6 I'm on. Print lines between (and excluding) two patterns I'm going to submit form using cURL, where some of the contents is come from other file, selected using sed  If param1 is line matching pattern from other file using sed, below command will works fine:  curl -d param1="$(sed -n '/matchpattern/p' file.txt)" -d param2=value2 http://example.com/submit   Now, go to the problem. I want show only text between 2 matching pattern excluding the matching pattern itself.  Lets say file.txt contains:  Bla bla bla firstmatch It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. secondmatch The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.   Currently, lots of "beetween 2 matching pattern" sed command won't remove firstmatch and secondmatch.  I want the result to become:  It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.

Groups of prime squared order C++ guarantees that variables in a compilation unit (.cpp file) are initialised in order of declaration. For number of compilation units this rule works for each one separately (I mean static variables outside of classes).  But, the order of initialization of variables, is undefined across different compilation units.  Where can I see some explanations about this order for gcc and MSVC (I know that relying on that is a very bad idea - it is just to understand the problems that we may have with legacy code when moving to new GCC major and different OS)? Markdown + Mathjax => PDF I've used LaTeX a lot in the past, but now, when comparing with StackExchange's great , I find it tedious, for short documents (&lt; 2 pages), to have to use pure LaTeX. For a short document, instead of having 30 lines as introduction: \begin{document} \documentclass[11pt,a4paper]{article} \usepackage[frenchb]{babel} \usepackage[latin1]{inputenc} \usepackage[T1]{fontenc} \usepackage{amsmath} \usepackage{amsfonts}  + &lt;lots of other things&gt; ...

This is **bold**. Windows 10 default programs keep changing Since the fall update last month, Windows 10 automatically keeps changing the default apps for certain types (mostly browser,pdf,mp3,jpg). I have tried changing them back from the Settings app as well as the Control Panel.  I have observed that this happens mostly while unzipping files using WinZip. Windows changes the default programs back to Microsoft recommended programs such as Edge, Photos, Groove etc.  Is there a way to restrict this from happening? Has anybody else encountered a similar situation? I couldn't find similar question anywhere so I'm asking this here. Do WALLS matter if I'm building the 6-inch brick defense from Corruption/Crimson for my city? Why didn't Elizabeth get cursed? What does 'Ign' , `Get` or 'Hit' mean when running an apt-get update? I had a bunch of errors in the output of sudo apt-get update:  duplicate entries and 404 not found errors.  Figured those out, I hope: I removed PPAs that didn't have any packages associated with them, then I removed out a duplicate entry in /etc/apt/sources.list.  It seems I have royally buggered it up.  Now most of the lines say Ign when I do sudo apt-get update.  How do I go about straightening out what I have screwed up?  I need to get rid of these Igns that are all over the place.  There are about 50% (eyeball guess) Igns!
