How to filter features in a layer? I am trying to display certain features in a shapefile-based layer using QGIS. I have found the subset function in the properties panel, which does exactly what i want, but is too tedious given that I have to manually sift through a large number of features. Is there a quicker way to do this?  I am using both shapefiles and postGIS best,  dietmar What's the best way to season a cast iron skillet? I just purchased a new cast iron skillet.

Today a couple of buffer overflows in NTP were announced , . It looks like updating my system to fix these issues is in order.   How can I find out if they have been fixed in the Ubuntu repositories, such that if I were to run:   sudo apt-get update sudo apt-get upgrade   then the fix would get installed and the vulnerability closed?   Edit: The selected answer specifically addresses the question of how to identify if a given CVE has been fixed or not, "Does Ubuntu generally post timely security updates?"  is certainly related but not identical How to search the internet for terms with special characters Frequently when EM waves are taught, it is said that the change in electric field causes a change in the magnetic field, which then causes a change in the electric field, and so on and so forth.   But from my understanding of basic electromagnetics, it is not necessarily a changing electric field that creates a change in magnetic field, but instead an accelerating charge. and it is this charge that creates both the electric and magnetic field. Again, from my understanding, a changing magnetic field is not generated by a changing electric field, but instead just happens to always be present perpendicular to a changing electric field due to the laws of electromagnetism.   Am I wrong? Or is the "mutual generation" concept between the electric and magnetic components of an EM wave an actual thing? Actionbar background is not being changed Version: Ubuntu 16.04  I have used it some weeks, but now it gives me this message when I'm trying to install software and update or upgrade:  Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) /var/lib/apt/lists/ locked   followed by this:    .  and another error:  ** (appstreamcli:4560): WARNING **: Exception: Unable to get write lock on /var/cache/app-info/xapian/default: already locked   What should I do? $x^a - 1$ divides $x^b - 1$ if and only if $a$ divides $b$ Let $x &gt; 1$ and $a$, $b$ be positive integers. I know that $a$ divides $b$ implies that $x^a - 1$ divides $x^b - 1$. If $b = qa$, then  $$x^b - 1 = (x^a)^q - 1^q = (x^a - 1)((x^a)^{q-1} + \ldots + x^a + 1).$$  I'm interested in the converse of the statement. If $x^a - 1$ divides $x^b - 1$, does this imply that $a$ divides $b$? I have a computer with Windows XP installed.  My user does not have a password.

Where to or how to ask "Best of" Questions for what software tools to use I am wondering where is a good place or how is a good way to ask a question on what software tools to use for a specific task.  A lot of the time when searching for information on these types of problems stackoverflow comes up with the top and actually useful discussions and answers, but the question is locked.  I completely understand the point of discouraging "best of" or list questions as discussed in this question () and agree they often aren't constructive enough to justify the effort in moderating them.  What I am wondering is where is the right place to have a discussion like this? Stackoverflow has a good and active community so perhaps there is another section or related site I can ask less specific questions. And I do find some value in reading people's opinions, even if subjective on issues like this.  Here are some examples of the kind of questions I mean:    and   First results in google when searching for those subjects and some useful discussion.  Perhaps asking a question like this but with a strict and detailed specification it might be considered a valid and reasonable question to ask on stackoverflow; perhaps it's just a case of re-thinking how to ask a question. Or perhaps there's a more relevant place for this kind of discussion. Please let me know what you think.
