How to Upgrade to 15.04 without upgrading to 14.10?
Can I skip over releases when upgrading?
Packed images used as background don't show up when reopening the file I have seen a single (1) mention of View port background images disappearing when the .blend file is saved and reopened.  However...the answers are not relative to what I am experiencing.  I go through the trouble of setting up four images (top, side, front, back) and then pack these images using External Data &gt; Pack all into .blend and then I save the .blend.  I save the file, open it back up, and the background images are all gone. Open up properties panel, look to see background images check box is unchecked, click add image, and choosing the open drop-down arrow...the data paths still show the list of images (packed into a specific folder textures).  They are still there, the data set is intact.  Why is It that I have to set this up each and every time I open the file.  It seems like earlier versions &lt;2.76B saved the images and saved the file with the background images check box checked without the need to set this up each time the file is reopened.  This is getting very frustrating due to the fact that a few of the background images mus be set up using Blender's rotate, scale and move tools to align the background image up with the model I have already fabricated.  Thanks! Apparently, you can speed up your computer by adding more RAM. Is the amount of ram to be added is directly or indirectly related to the amount of hard-disk  space, processor speed, Motherboard etc... Can the memory of a RAM be compared with Virtual Memory and Cache Memory?  Note: About my PC Configuration: Intel core i5 processor, Motherboard DP55WB 4GB RAM, 700 GB Hard-disk space. How can I write % into a file? How can I write % into an auxiliary file? % will not work, because LaTeX thinks that I start a comment with it (in the main file, not in the auxiliary file!), and \% will write \% into the file. How can it be accomplished?   \documentclass{article} \begin{document} \newwrite\outfile \immediate\openout\outfile=example.dat \immediate\write\outfile{%}% will not work, of course, but neither \% \immediate\closeout\outfile \end{document} Who's at fault with this error concerning csquotes and LuaLaTeX? I ran into this with the package lilyglyphs but I'm not sure whose fault this error is.  When I compile the following with lualatex:  \documentclass{article} \usepackage{csquotes} \MakeOuterQuote{"} \EnableQuotes \begin{document} \directlua{print("hello")} \end{document}   I get an error saying   \directlua]:1: unexpected symbol near '\'. l.6 \directlua{print("hello")}    Now suppose that I do not directly write \directlua in my document, but I include a package that does it internally. Such as   \documentclass{article} \usepackage{fontspec, csquotes, lilyglyphs} \MakeOuterQuote{"} \EnableQuotes \begin{document} \wholeNote \end{document}   I have no knowledge why compilation fails, because the error now becomes   ! Missing number, treated as zero. &lt;to be read again&gt; \begingroup l.7 \end       {document}    From my user point of view I did nothing wrong, because I'm using the public API provided by the packages. The csquotes documentation specifically says:     Note that all characters are automatically checked for validity as they are allocated. This package will reject characters which are unsuitable as active quotes... In sum, the following   characters will be considered as reserved by this package:   A–Z a–z 0–9 . , ; : ! ? ' - # $ % &amp; ^ _ ` ~ \ @ * { } [ ]    So my question is whose fault is this error?   My fault, the user's fault, because I should have known (but how?) that even though the quote is not listed as unsuitable in the csquotes manual, it actually is? The fault of the implementation or documentation of csquotes for failing to mention " as unsuitable? The fault of the implementation of the \directlua command because it doesn't prevent LaTeX catcode changes/active characters from impacting its argument? A shortcoming of TeX itself because of its global state based architecture? How do I install Adobe Flash player? Which is the biggest object which can interfere with itself? How can I get barcode-scan information into my photo metadata, onsite, untethered? I need a DSLR camera with a barcode scanner for on-site tours photography, which means it needs to be untethered! The image would have to contain the barcode scanned information in the image metadata or in the name itself.  I've seen solutions like, Foolography and a $2600 Canon Studio Edition launched in 2010. But I'm not sure of either those products!  So I'm asking the gurus here how I can get this working, which camera would I need and any accessory necessary?  I'm trying to recreate something like I saw the on-site volume photographers do in Disney's parks. Neural Network: MLP for regression with 3 continuous features, 1 categorical I am starting to study Neural Network. I want to build a MLP where I will feed it:   3 features which are continuous one feature which is categorical (48 classes)   How can I do this?  Before adding the categorical feature, I was using 'relu' activation function and 'lbfgs' as a solver in MLPRegrssor in sklearn.  I was wondering: how can I integrate this variable into the network? Should I do one-hot encoding? Should I keep relu as activation function or should I try sigmoid, softmax or something like that?

Grub rescue after installing Ubuntu on a external HDD from USB How to use "`" in the same way it is used on the SE websites? I want players to be able to click text to run an OP command even if that player is not an OP. For example something like:  Console: Do you want to enable Fly? [If you do, Please click here]  *Player1 clicks that text*  Console: /fly Player1   Is something like this possible? Why is the well ordering principle counter-intuitive? I read  that while 'The Axiom of Choice agrees with the intuition of most mathematicians; the Well Ordering Principle is contrary to the intuition of most mathematicians'. I don't understand why this is so. According to Wikipedia, 'the well-ordering principle states that every non-empty set of positive integers contains a least element'. This is quite a straightforward definition. Is it the way you derive the equivalence of the Axiom of Choice and well ordering principle that makes it counter-intuitive or the definition of the least element? Why does the wire-frame material fades across the object? Why does the wire-frame material fades across the object?  Here is what I did - I created a new material and I selected on "Wire" and I made it shadeless. Then, I created a new material and assigned the new material on the on the object. However, doing it that way, it allows me to render both materials - "Wire" and "Surface". Then I get a fading result like this -    But I want all of the edges to be shown, not a fading result. How can I make that?  Here is the blend file if anybody wants to check it out - This question is essentially the same as one of my , except the only difference is that I am using "only" to change the text at the same location (i.e., ). In other words, I am destroying my earlier text as I go, and not adding new ones underneath the previous ones.   Since the text for the first "only" is shorter than the second "only", therefore the image will shift location. I would like for the image to remain at its location.   Here is an example     it may not be obvious but the second image is higher up than the first.  The code is here, can someone find a solution?  \documentclass{beamer}  \usepackage{graphicx}  \title[Title]{Presentation} \author{Sandro Botticelli} \institute{Italy} \date{1484}  \begin{document}   \begin{frame} \begin{figure} \includegraphics[scale = 0.8]{Venus}     \caption{Nascita di Venere} \end{figure}  \only&lt;1&gt;{In the centre the newly-born goddess Venus stands nude in a giant scallop shell.
