copy/paste style to multiple layers in QGIS
Change style properties of several layers simultaneously?
Is there actually a 0 probability of finding an electron in an orbital node? Does $G\cong G/H$ imply that $H$ is trivial? Why are there non-visible objects in my final render? I have a generic class in my project with derived classes.  public class GenericClass&lt;T&gt; : GenericInterface&lt;T&gt; { }  public class Test : GenericClass&lt;SomeType&gt; { }   Is there any way to find out if a Type object is derived from GenericClass?  t.IsSubclassOf(typeof(GenericClass&lt;&gt;))   does not work. I have for quite some time now tried to find a satisfactory answer to this, but I haven't yet. In perturbation theory, with small parameter $\lambda$, we expand the eigenstate as  $$| E \rangle=| E^{(0)} \rangle + \lambda | b \rangle + ...$$  Where $| E^{(0)} \rangle$ is an eigenstate of the unperturbed Hamiltonian. The problem is that when there is degeneracy, there is a choice of these eigenstates. I know the answer is that they are chosen to be eigenvectors of the perturbing Hamiltonian, but my question is why. I am moving from Malaysia to the US, and planning to bring my desktop computer with me. I plan to pack it in my checked-in luggage. Will the computer risk being damaged? Any precaution should I take to reduce this risk? Will there be any trouble with the airline or immigration about bringing computer? Windows 7 equivalent for ntrights.exe Using OpenSUSE leap 15.1 10.2.29-lp151.2.9.1-x86_64 from vendor OpenSUSE (installed)  CREATE TABLE testtab2(     my_id2 INT AUTO_INCREMENT,     name2 VARCHAR(10),     comment2 VARCHAR(20),     PRIMARY KEY (my_id2) );   testtab.txt:  |Roger |hurray   | |George|today    | |Paul  |yesterday| |John  |last year| |Ringo |tomorrow |   LOAD DATA LOCAL INFILE 'testtab.txt' INTO TABLE testtab FIELDS TERMINATED BY '|';   works fine with linenumbers (my_id) 1-5  INSERT INTO testtab (name,comment) VALUES ('Beatles','band');   this gets linenumber (my_id) 8 - should be 6.  If testtab.txt have 8 records and using INSERT INTO 1 record this gets linenr (my_id) 16. This happens in other tables too - one moved from 199 to 256.  Anyone who can solve the problem? Food in the Star Wars Universe? 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'. Centos mysql version is 5.5 however PHPmyadmin still says version 5.1 When i run the following in my console:  [root@****~]# mysql -u root -p -e 'SELECT VERSION();' Enter password: +-----------+ | VERSION() | +-----------+ | 5.5.39    | +-----------+   Which should be the correct version.  However when i enter my PHPMYADMIN on my server it has the following specs:  Server: Localhost via UNIX socket Program: MySQL Programversion: 5.1.73 - Source distribution   So which version is the correct one and how do i make sure that the database is running on 5.5?  Note  I have already restarted sql several times without any changes Use Unity API from another Thread or call a function in the main Thread How do you measure pedal axle/spindle size?  Replacement pedals and accessories specify a size like 9/16" or 1/2".  How do I measure my current pedal to see what I need?  Is it just a matter of putting the pedal threads in a caliper and measuring the outer diameter of the threads across the axle/spindle?  Or do you need to measure the solid part, excluding the threads?

This was a bad decision, because it caused me to run into a .   The solution is to reinstall nodejs and npm. Unfortunately when I go to install npm using sudo apt-get install npm it doesn't work.  The full error in the terminal is here:  Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that  some required packages have not yet been created or been moved out of Incoming.

What can I do to get npm properly installed and running again?  Thanks. I once already asked a very similar question; . But this is some what different.

Do I have to use English when posting a question, an answer or a comment on a Stack Exchange site? How can I check if a package is installed (no superuser privileges)? At our university we can get almost any ubuntu package installed we want, but we are not superusers ourselves (we need to request packages being installed).  With some libraries it is not always easy to know whether the package is already installed or not. Is there a simple way/command to check this? Objects with transparent texture not always show transparency in 3dview For some reason objects don't show their transparency all the time.  In this image the circles in red are suposed to be transparent like the ones in green.    When I select the object in the back, all objects in front of it become opaque.    When I select the two objects that are opaque, then they become transparent as they sould be.    The display is in GLSL mode  These are the material and texture properties      I'm not worried about the final render, just the editing view. I would like to see the actual transparency at editing time only, because the scene is to be imported in a third party game engine.  Blender is v2.68   is the blend file I tried to change network interfaces name on this new Ubuntu 16.04 LTS version but doesn't have the /etc/udev/rules.d/70-persistent-net.rules.  So, I tried to use /lib/udev/write_net_rules but it not exist.  Why do I need this modification? Because I'm using a tool to Simulate virtual platforms that use flex licensing and the authentication need to be in eth0 interface name.  Any suggestion?
