Upgrading from version 4 to 5
Export nodes from Drupal 4?
How can I initialize normal array member variable in initializer list? Is there a difference between "think of something" and "think about something"? I've also met "have heard of/about something". permanent hat-like thing? I really like how, in the winter bash, there are hats. They are pretty cool and actually encourage me to get badges, something I didn't care about before. I think there should be something like this, but all year round, to encourage people to get badges. Badges, to me, seem currently pretty useless and I never want to get any because...there is no good reason to. Hats: well, hats are just awesome Stretch and scale CSS background Is there a way to get a background in CSS to stretch or scale to fill its container? I am trying to incorporate a wms feed in the British national grid projection (EPSG:27700) into a openlayers 3 project. I initially had used this wms layer in an openlayers 2 application using the following syntax:  new OpenLayers.Layer.WMS(         "ukimage",         "http://www.linktowms",         {             "LAYERS": 'ukimage',             "STYLES": '',             format: state.image_format         }, {     buffer: 0,     displayOutsideMaxExtent: true,     isBaseLayer: true } );   But I am having trouble converting this over to openlayers 3. I first tried setting the map projection to British national grid (view: new ol.View({ projection: 'EPSG:27700'}) as I had in the openlayers 2 app, but this produced the error  TypeError: h.B is not a function    and a white map.   When I try and use proj4 to convert the projection to EPSG:3857 as described here:  I get the same error:   TypeError: h.B is not a function    and again a white map.   my wms request is generally a varient of:  new ol.layer.Image({       source: new ol.source.TileWMS({         url: 'http://www.linktowms',         params: {'LAYERS': 'ukimage'},       })     }),   (I tried adding projection but that didn't help)  I am trying to work out if the image is even getting loaded from the WMS feed, but the syntax seems to have changed significantly from openlayers 2, instead of the properties and functions that have rather descriptive names, there are a now lots of short functions with names like Ua and Ig, which leaves me a bit in the dark as to what's actually going on when I try and inspect the layer with firebug.  I don't mind what projection the application is in, as I can re-project my other layers to match the basemap, so basically any way of using this EPSG 27700 WMS layer in openlayers 3 would be great. How is missing data calculated on Likert Scale? Why is the sum of the digits in a multiple of 9 also a multiple of 9? The sum of the digits in $9 k$ (where $k$ is an integer) is a multiple of $9$: for example   $$9\cdot 1=9$$ $$9\cdot 7=63 \qquad  \text{and } 6+3=9\cdot 1$$ $$9\cdot 11=99 \qquad \text{and }  9+9=9\cdot 2$$  But why? Since drush 9 (drupal 8.4 requirement), alias @sites does not seem to be implemented anymore (or yet ?).  $ drush @sites cr The alias @sites could not be found.   Is this a way to get the same behavior that does not consist of typing my 300 alias in a config file ? Using old version of numpy even with a newer version installed How to sort a character vector where elements contain letters and numbers in R? In the Harry Potter series is it clear that magically-inclined individuals (witches/wizards) will live to be considerably older than their Muggle counterparts? From the question , it is given that Dumbledore was roughly 115 years old when he died, and at that age he hardly seemed ready to kick the bucket naturally.  With that in mind, how old will a wizard typically live to be, barring accidents or murder? I am writing my CV using moderncv package, everythig is nice but I have a problem with \cventry command. I have something like this:   (it means 2010 - now)  I would want to have this in one line, rather than in two lines. I tried looking into the moderncv style files but with no success. What can I do to achieve the effect I want? In Ubuntu 17.10 ubuntu upgraded Nautilus (File Browser) to version 3.26.0. New nautilus is not using file-roller anymore, it has  to an integrated compression mechanism.     This makes it complicated to create encrypted archives and/or different types compression archives that file-roller does provide.  How to make nautilus use file-roller as before?  Related question: What really allows airplanes to fly? We often get questions on bicycles.stackexchange about fitting wider or narrower tires to bicycles. We have a large number of these with answers suiting the specific bike or style of bicycle in question, but I have been unable to find one that provides a generic answer covering off all things that need to be considered. For most bicycles, the answer is the same regardless of the specific style and sizes of tires in question.   This is intended as a canonical question that we can point closed questions to. Convergence of the series $\sqrt[n]n-1$ Let $a_n=\sqrt[n]n-1$. Does $\sum_{n=1}^\infty a_n$ converge? $$ \sum_{i=1}^N\left\lfloor\frac{N}{i}\right\rfloor $$ Is there a closed form expression to the above sum? (Mathematica doesn't give me anything) Knife tool doesn't cut obscured edges I'm using Blender 2.66,  I find that the knife tool (K) doesn't work the way it used to.     Dragging across an obscured edge, even if selected, doesn't cut it. There seems to be no way to activate the option to do a midpoint cut or multiple cuts. How do I ask LaTeX to exactly fill up a page? I understand that I can control interline spacing in LaTeX in a number of ways. The commands like ,  ,  come in handy in controlling the interline spacing. Each has its own speciality and circumstances of usage, as we can find in these discussions (, , ).  If want to go for a ready made solution for controlling line spacing, packages like  come in quite handy (built-in commands like \onehalfspacing or \setstretch for more finer controls).  Anyway, my problem is a bit different. I have some text (both in paragraph and list mode) which I want to fill up exactly one page. To complicate the scenario, it may even contain equations and graphics. (Let us leave aside floats.)   If I want to solve the problem statically, all I will have to is to play with some value of \baselineskip (or  \setstretch) until satisfied. While this works good for most of the cases, I will have to go through the process again when I want to delete or add some texts.  Would it be possible to have a dynamic value for  \baselineskip or  \setstretch so that my text always fills up one page? (Definitely within reasonable limits.)  Another idea will be to use a number of \vfills between some pieces of texts. But I think that this technique is usable for cover pages only.  I am not putting here an MWE. I think that one is not applicable.    The problem is not a theoretical one, I am preparing some kind of handout which I want to fill-up exactly one page. I would like to create a half-turn staircase without a landing. Is there an easy way to accomplish this without having to manually calculate and create each step individually?  Here’s an image similar to what I would like to achive:    I have found the Archimesh add-on including . While I can bend the created stairs, I haven’t found any way to get anywhere close to the image above. My stairs just always look out of shape and I don’t know how to get the outline of the staircase into a square.  I should mention that I only have very little experience with Blender modeling, so it’s well possible that I’m just missing some curve modification basics. Perhaps Archimesh is also the wrong approach for this in the first place?
