I need some advice for the output settings in Blender 2.8...  When I render an image with 2000px x 2000px the output has the resolution of 72x72.    Now when I render the same image with 3000px x 3000px the output resolution is... still 72x72. When zoomed in the image shows ugly pixels...     So: Is there a chance / way to have the resolution output at 300x300 (ppcm)? The only solution I came up with is to increase the image size massively... and therefore the rendertimes insanely.   Let's see if you guys can come up with an answer. Thnx
Is there a way to output for Print. I want to save in a higher DPI than the default 72dpi say 300dpi that's a good quality for printed pieces. I tried downloading an add-on but don't know if I am installing it correctly it isn't showing up but the bar in python is green. I'm using the 2.69 version of Blender. If no such feature exists what size have any of you found best for print quality. Thank you
"I saw him crossing" vs. "I saw him cross" I saw him crossing the road.   I saw him cross the road.   Which one is correct and why? I live &amp; work in the UK.  Having pretty much exhausted all of the avenues I can find for saving (none of which have great returns anyway at the moment, obviously), I have recently started looking to buy my first house.  I have a reasonable sum saved up for a deposit, but I'm wondering what to do with that in the mean time, as a fair amount of it is not currently earning any interest. For the moment, I have put any surplus, that I'm not earning interest on into premium bonds, just in the off-chance that I win something with it, but this is obviously more of a lottery than an investment, and I'm not 'expecting' to win anything noteworthy with it.  Ideally, I would like to buy a house within the next year or so, so investing in the stock market is not really an option, as I understand the commonly accepted advice is that you invest with a minimum 5 year horizon.  What other options do I have for any surplus cash while I look for a house? How to extract the boundary of a raster image? Is it ever revealed what Crookshanks is? When Hermione first got her pet thing Crookshanks, there was a mention that it looked kinda like a cat, but wasn't.  Was it ever revealed what Crookshanks really was? How can I automatically center an image? I use:  \documentclss{mwrep} ... \begin{figure}   \includegraphics{a.jpg} \caption[Long caption]{Caption} \label{pic-a} \end{figure}   How can I make images to be always visible on the center of page? (To be more specific: the center of the image should be between the left and right margin - I use different left and right margins). I don't want to put anything after every \begin{figure} in my document.  Important: I don't want to waste an entire page on a single image at the very center of the page. I want only horizontal alignment. (left &lt;-> right) Prove that the functions $f(z)$ and $\overline{f(\overline{z})}$ are simultaneously holomorphic.   I take this to mean that $f(z)$ is holomorphic if and only if $\overline{f(\overline{z})}$ is holomorphic.  Let $g(z)=\overline{f(\overline{z})}$. Note that $\overline{g(\overline{z})}=f(z)$. So it suffices to prove that if $f(z)$ is holomorphic, then $g(z)$ is holomorphic.  Write $f(z)=u(z)+iv(z)$. Since $f(z)$ is holomorphic, the real and imaginary parts satisfy the Cauchy-Riemann equations:  $$\frac{\partial{u(z)}}{\partial{x}} = \frac{\partial{v(z)}}{\partial{y}}, \frac{\partial{u(z)}}{\partial{y}} = -\frac{\partial{v(z)}}{\partial{x}}.$$  We have $g(z) = u(\overline{z})+i(-v(\overline{z}))$. To prove that $g(z)$ is holomorphic, we must prove that its real and imaginary parts satisfy the Cauchy-Riemann equations:  $$\frac{\partial{u(\overline{z})}}{\partial{x}} = \frac{\partial{(-v(\overline{z}))}}{\partial{y}}, \frac{\partial{u(\overline{z})}}{\partial{y}} = -\frac{\partial{(-v(\overline{z}))}}{\partial{x}}.$$  How can we obtain this from the above relations? I would like to ask a question not about software architecture, but physical architecture, i.e., the design of buildings and other elements of the "built environment".  I was looking for a Stack Exchange site to ask what the meaning is of the huge stone symbols on the side of the new Scottish Parliament building. EDIT: As of Java 8, static methods are now allowed in interfaces.  Here's the example:  public interface IXMLizable&lt;T&gt; {   static T newInstanceFromXML(Element e);   Element toXMLElement(); }   Of course this won't work.  But why not?  One of the possible issues would be, what happens when you call:  IXMLizable.newInstanceFromXML(e);   In this case, I think it should just call an empty method (i.e. {}).  All subclasses would be forced to implement the static method, so they'd all be fine when calling the static method.  So why isn't this possible?  EDIT: I guess I'm looking for answer that's deeper than "because that's the way Java is".   Is there a particular technological reason why static methods can't be overwritten? That is, why did the designers of Java decide to make instance methods overrideable but not static methods?  EDIT: The problem with my design is I'm trying to use interfaces to enforce a coding convention.  That is, the goal of the interface is twofold:   I want the IXMLizable interface to allow me to convert classes that implement it to XML elements (using polymorphism, works fine). If someone wants to make a new instance of a class that implements the IXMLizable interface, they will always know that there will be a newInstanceFromXML(Element e) static constructor.   Is there any other way to ensure this, other than just putting a comment in the interface? Getting ssh to execute a command in the background on target machine Why did Eve die with Maelon's data available? I saved Wrex in ME1, I saved Maelon's data in ME2, the import screen in ME3 confirmed this.    When I get to the missions on Tuchanka, I completed every one of the side missions before starting the mission where they take down the Reaper and distribute the genophage cure.  Then when I finally get to the lab, Mordin tells me that Eve has died.    Yet every site I've been to says that keeping the data allows her to live.  So why did she die? I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that.  I just tried to upload a screen shot but since I'm new it won't allow me to.  I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following:  COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse)  E: The list of sources could not be read.,  E: The package list of status file could not be parsed or opened.   How do I report bugs?  What can be done about this.  I have searched and everything everyone says to do leads me back to the same line error message.  So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software. When writing custom classes it is often important to allow equivalence by means of the == and != operators. In Python, this is made possible by implementing the __eq__ and __ne__ special methods, respectively. The easiest way I've found to do this is the following method:  class Foo:     def __init__(self, item):         self.item = item      def __eq__(self, other):         if isinstance(other, self.__class__):             return self.__dict__ == other.__dict__         else:             return False      def __ne__(self, other):         return not self.__eq__(other)   Do you know of more elegant means of doing this? Do you know of any particular disadvantages to using the above method of comparing __dict__s?  Note: A bit of clarification--when __eq__ and __ne__ are undefined, you'll find this behavior:  &gt;&gt;&gt; a = Foo(1) &gt;&gt;&gt; b = Foo(1) &gt;&gt;&gt; a is b False &gt;&gt;&gt; a == b False   That is, a == b evaluates to False because it really runs a is b, a test of identity (i.e., "Is a the same object as b?").  When __eq__ and __ne__ are defined, you'll find this behavior (which is the one we're after):  &gt;&gt;&gt; a = Foo(1) &gt;&gt;&gt; b = Foo(1) &gt;&gt;&gt; a is b False &gt;&gt;&gt; a == b True This is a  about Fighting Spam.   Also related:                    There are so many techniques and so much to know about fighting SPAM. What widely used techniques and technologies are available to Administrator, Domain Owners, and End Users to help keep the junk out of our inboxes?  We're looking for an answer that covers different tech from various angles. The accepted answer should include a variety of technologies (eg SPF/SenderID, DomainKeys/DKIM, Graylisting, DNS RBLs, Reputation Services, Filtering Software [SpamAssassin, etc]); best practices (eg mail on Port 25 should never be allowed to relay, Port 587 should be used; etc), terminology (eg, Open Relay, Backscatter, MSA/MTA/MUA, Spam/Ham), and possibly other techniques. Let's say I have a class that has a member called data which is a list.    I want to be able to initialize the class with, for example, a filename (which contains data to initialize the list) or with an actual list.  What's your technique for doing this?  Do you just check the type by looking at __class__?  Is there some trick I might be missing?  I'm used to C++ where overloading by argument type is easy. How to create a hole in a polygon in QGIS?

How to change the name of document elements like "Figure", "Contents", "Bibliography", "Appendix", etc.? I'd like to modify the names used to typeset some of my document elements.
