I'm following a Ducky3D tutorial  The alpha clip in the material settings is supposed to show an array of see through planes. Without the alpha clip, it's not see through. How do I get the alpha clip to render? No matter what the alpha clip won't show in an Eevee render. I don't want to use Cycles because it looks weird. Viewport display Vs Eevee below Viewport Display:  Eevee Render:  Cycles Render:
When two objects -one of them transparent- intersects it creates some artifacts visible even in the alpha channel. Even with 1024 transparent bounces the artifacts remain.    In the example file there are two cubes in the same position, one transparent and one emission.    What is causing this? Any way to get rid of this artifacts?
Conjugating verbs for nouns referring to groups of people Possible Duplicate:          Frequently when reading tech articles, I see sentences like "Microsoft have released ..." or "Apple have announced ...". This seems wrong to me because the nouns are singular; Microsoft and Apple are individual companies, even though they refer to groups of people. I have not seen this usage outside of tech journalism, but it's pervasive enough that it makes me wonder: is this actually the correct usage?  As a follow-up question, is it correct to use a plural pronoun for a singular antecedent like this? For example, "Apple has announced they are changing their name to Orange" or "Apple has announced it is changing its name to Orange". The second form seems technically correct but sounds awkward. The app keeps asking for a nickname, and I have entered dozens of names, but it keeps saying that the names aren't available. How can I find an available name? Proof of $\gcd(a,b)=ax+by\ $ [Bezout's identity] The abstract environment changes the \linewidth for the whole document In the article class, it seems that using the abstract environment has an effect to the rest of the document. More precisely, it seems that it redefines the \linewidth, which equals \textwidth without abstract, is smaller with the abstract. My feeling is that \linewidth is redefined for the abstract environment, but the value is not reseted at the end of the abstract.  Here is a minimal example:  \documentclass{article} \begin{document} \abstract{This is an abstract. This is an abstract.}\bigskip  This is text. This is text. This is text. This is text. This is text. This is text.\\  \rule{\textwidth}{3em} \rule{\linewidth}{3em} \end{document}   The output is not the same if you comment the \abstract line or not.  Do you have the same problem as I do when you compile (if not, I will upload some PDF files to show)? Is this a (known) bug in LaTeX2e? How can we circumvent the problem?

Is it possible to mount a VirtualBox drive image (.vdi) so the contents can be viewed in Nautilus etc.?  I have a windows 2000 .vdi which won't boot ("inaccessible boot device") after upgrading from VirtualBox 2.x to 3.1.6. I believe the IDE drive details have changed and that all I need to do is access the internal drive image and edit the Windows boot.ini to point to the new location. Why are the endpoint lines of intervals (`|-|`) not shown completely? I use \draw[|-|] () to (); to draw a few intervals.  I expect that each interval is rendered like |----| (see the 2nd and the 3rd intervals in the figure below).  However, the top and the bottom intervals below show only a half of their endpoint lines (i.e., |).  Why are these endpoint lines (|) not shown completely? How to show them?        \documentclass{standalone} \usepackage{tikz}  \begin{document} \begin{tikzpicture}   \draw[|-|, red] (0,0) to (1,0);   \draw[|-|, red, dashed] (0,1) to (1,1);   \draw[|-|, blue, dashed] (0,2) to (1,2);   \draw[|-|, blue] (0,3) to (1,3); \end{tikzpicture} \end{document} Adding popup message box before tool execution with ArcPy and ArcMap I want to add a box message to pop up before execution of a button tool.

What is different about the Mac ISO image? How do you concatenate characters in java? Concatenating strings would only require a + between the strings, but concatenating chars using + will change the value of the char into ascii and hence giving a numerical output. I want to do System.out.println(char1+char2+char3... and create a String word like this.  I could do   System.out.print(char1); System.out.print(char2); System.out.print(char3);   But, this will only get me the characters in 1 line. I need it as a string. Any help would be appreciated.  Thanks Is there anything beyond subtle hints that Jack becomes the Face of Boe? When is the union of a family of subspaces of a vector space also a subspace? It is not difficult to prove that the union of a chain (or, more generally, a directed family) of subspaces of a vector space $V$ is a subspace of $V$.   Given a family $\mathcal{F}$ of subspaces of a vector space $V$ such that the union of $\mathcal{F}$ is a subspace of $V$, is it true that $\mathcal{F}$ is a directed family?  If not, is there a "nice" characterization of families of subspaces whose union is a subspace? What is the best way to store user settings for a .NET application? I have a .NET 2.0 Windows Forms application. Where is the best place the store user settings (considering Windows guidelines)?  Some people pointed to Application.LocalUserAppDataPath. However, that creates a folder structure like:     C:\Documents and Settings\user_name\Local Settings\Application   Data\company_name\product_name\product_version\   If I release version 1 of my application and store an XML file there, then release version 2, that would change to a different folder, right? I'd prefer to have a single folder, per user, to store settings, regardless of the application version. ­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­ Let's say I have a video running in an application.  If I hover my mouse over the taskbar, it shows a little popup windows that diplays the video  (aero peek).  Sometimes I'm running a maximized window and I want to have this little screen always popped up.  (Kind've like when your using the TV Guide menu, you still see a little clip of the video) I've been doing ASP.NET development for a little while now, and I've used both the GridView and the DataGrid controls before for various things, but I never could find a really good reason to use one or the other. I'd like to know:  What is the difference between these 2 ASP.NET controls? What are the advantages or disadvantages of both? Is one any faster? Newer? Easier to maintain?  The intellisense summary for the controls doesn't seem to describe any difference between the two. They both can view, edit, and sort data and automatically generate columns at runtime.  Edit: Visual Studio 2008 no longer lists DataGrid as an available control in the toolbox. It is still available (for legacy support I assume) if you type it in by hand though. Error -504 on appliation installation Yes. I've read all other questions regarding this problem. Like this one:  It's the same problem as this one but with more background information and an other app:   The details: My device is an Ulefone Be Touch 2 running Android 5.0.  My connection is perfect. To be sure I tried different networks, among them are 3G, 4G and wifi on ADSL, VDSL, cable and fiber.

With English not being my first language, I usually need support for at least two languages when using features like auto-correct and dictation.  Is it possible to toggle the language which is used for dictation via a shortcut?  As of now, I always have to manually navigate through the menus in the System Preferences which if far from convenient. I've tried to see if there are any pre-defined actions in Automator, but found none. calculating resistance for LED strips to use as parking lamps and turn signals I'm installing LED strips in my car's tail lamps to convert it from conventional bulbs to LEDs. I have a understanding of what I'm doing but not the complete knowledge to make the circuit work correctly without doing some guessing so I figured I would ask here.   I'm planning on working with and I need a length of 16", 15" and 14" to make then look correct in my housings. When I did the math the 19.7" strips have about 1.5 LEDs per inch and need to be segmented into 3 LED groups so I may have to get creative with the placement.   Ffom what I understand I need 2 diodes and a resistor. One diode on the parking lamp power, and one on the turn signal/brake power and then a resistor on the parking lamp  wire to step down the voltage enough to make them dim enough to use as a parking lamp and distinguish it from the brighter turn/brake lamps.  Does anyone know what size resistor and what size diode to use in this project? The voltage, with the car running, is around 13.8V to the rear lamps. I figure it should be running around 7V to the LEDs to light them as parking lamps.  Also will leaving out a cluster of 3 LEDs change the strips intensity to where I'll need different resistors for each strip? Let $G$ be a group of order $150$.  I must show that it has a normal subgroup of order $25$.  The hint says to show that is has a normal subgroup of order $5$ or $25$.  Now from Sylow, I know that the number $n_5$ of Sylow-$5$ subgroups (which each have $25$ elements) must be either $1$ or $6$, since $n_5$ must also divide $6$.  Now clearly if $n_5=1$ we are done, so I can assume that $n_5=6$.  My problem is I haven't figured out how to use this information (I am going for a contradiction, just based on what the problem asks me to prove).  I know by Cauchy's theorem I can get a subgroup of order $5$, but I don't see immediately if it must be normal.   Any direction I should try to be moving?
