What is the easiest way to create a color gradient texture in blender?   Original Question:   I want to apply a color gradient texture to an object, but I cannot figure out how to do so. I have read several guides that point to a "gradient texture" texture type when using the cycles render engine, but it just does not exist in my version of blender. I have tried switching back and forth between rendering engines, restarting blender, all sorts of stuff.    I am using Blender 2.74 in manajaro (arch linux based distro).
I am wondering how to recreate some kinds of effects (you can easily do in Photoshop) in Blender.  I want to create the gradient textures like ones pictured below, should I render objects and blur them in compositor? Or can I achieve it using only material nodes?
Uk visa refused as self employed I was using this:    To try and create numbered examples in my document.  However, when I load it and put the example exe in that link in one of the separate Tex files (Introduction.tex) I include in main.tex, I get:  ./Chapters/Introduction.tex:14: TeX capacity exceeded, sorry [parameter stack s ize=10000]. \gb@ifnextchar #1#2#3-&gt;                        \let \reserved@d =#1\def \reserved@a {#2}\def \reserv... l.14 ... and political news \cite{washington_post}                                                   .

How to move an element into another element? IMAP: how to move a message from one folder to another (using the IMAP commands, not with the assistance of any other mail package) How to reverse PCA and reconstruct original variables from several principal components? Principal component analysis (PCA) can be used for dimensionality reduction. After such dimensionality reduction is performed, how can one approximately reconstruct the original variables/features from a small number of principal components?  Alternatively, how can one remove or discard several principal components from the data?  In other words, how to reverse PCA?    Given that PCA is closely related to singular value decomposition (SVD), the same question can be asked as follows: how to reverse SVD? Dirac Delta function inverse Fourier transform We know that the Fourier transform of the Dirac Delta function is defined as $$\int_{-\infty}^{\infty} \delta(t) e^{-i\omega t} dt = 1,$$  and if I were to reconstruct the function back in time domain, the inverse Fourier transform is defined as  $$\delta(t) = \frac{1}{2\pi}\int_{-\infty}^{\infty} e^{i\omega t} d\omega.$$  How do I compute this integral analytically? How to find the foreach index? I’m studying a PhD in Theoretical Physics (quantum field theory, to be specific), but I would like to learn more about black holes (and related areas. Does anyone have any suggestions for textbooks/available notes on these subjects for people without much background in them? Obviously I’m very comfortable with mathematics and physics in general so I’m not looking for “pop science” material. Is it possible to associate non-blend files with Blender? Is there a way to make Blender auto import files that are not .blend when you open them?  For example if you open a .fbx file by double clicking on it, and you have Blender set as default application, then import it to a new .blend.  Is it possible to make Blender import this .fbx file just like you would do it manually by using File > Import > FBX?  By default, Blender just opens up and loads default new scene when you open anything that is not .blend file. Just switched from 10.04 to 11.10. I'm wondering about the limited options in the GUI for managing users and groups. Where is the old GUI to change groups, id's, etc. I know that I can do this from cli, that's no problem.

WinError 32 error when trying to delete shapefiles with QGIS python What is the difference between an "API," a "framework," an "IDE," and an "engine?" I am just starting out trying to learn to develop games. At first I thought C++ and OpenGL were the tools a beginner would start out to make a game, but quickly found out the OpenGL was just a API for graphics. Then I thought C++ and SFML were what I needed to learn to make a game, but found out the SFML was a media framework that could be used to make games but wasn't a game engine.  I don't want to use a software that does all the work for me, I want to code my own game, the way a game programmer would. I don't understand the difference between a IDE, framework, API, and a engine; What separates them from each other? Do some game programmers use the SFML framework, while other programmers use a game engine? New figure environment I am writing my PhD thesis. In my manuscript I have Figures in the text and Photographic plates (a figure of figures) in the annexes. The two elements are different and I would like create a new environment of Plate that follows the same structure of the Figure environment. Where can I find the Figure environment to modify it?  The new environment table should have exactly the same structure than the figure environment but replacing the word figure by the word Planche (in French). Two column float with [t] using the cas-dc template I am using the cas-dc template for Elsevier.

I don't see anything mentioned that strictly forbids it, unless I missed this. Anyone know why? Proving $1^3+ 2^3 + \cdots + n^3 = \left(\frac{n(n+1)}{2}\right)^2$ using induction How can I prove that     $$1^3+ 2^3 + \cdots + n^3 = \left(\frac{n(n+1)}{2}\right)^2$$    for all $n \in \mathbb{N}$? I am looking for a proof using mathematical induction.  Thanks Who uses Dual_EC_DRBG? Recent news articles have suggested that the NSA may be involved in trying to influence the cryptography in public standards or commercially deployed software, to enable the NSA to decrypt the encrypted traffic.  For example, .  The New York Times article specifically mentions a 2006 NIST standard, where two Microsoft engineers later discovered a serious problem in the scheme.  The New York Times article explains how the standard was written by the NSA, who pushed the scheme hard:     Simultaneously, the N.S.A. has been deliberately weakening the international encryption standards adopted by developers. One goal in the agency’s 2013 budget request was to “influence policies, standards and specifications for commercial public key technologies,” the most common encryption method.      Cryptographers have long suspected that the agency planted vulnerabilities in a standard adopted in 2006 by the National Institute of Standards and Technology, the United States’ encryption standards body, and later by the International Organization for Standardization, which has 163 countries as members.      Classified N.S.A. memos appear to confirm that the fatal weakness, discovered by two Microsoft cryptographers in 2007, was engineered by the agency. The N.S.A. wrote the standard and aggressively pushed it on the international group, privately calling the effort “a challenge in finesse.”    After some sleuthing, I'm pretty certain this is a reference to the  pseudorandom number generator scheme described in NIST SP 800-90.  The weakness is that Dual_EC_DRBG appears to contain a backdoor, and anyone who knows the backdoor can totally break the PRNG.  The weakness was first described in  and was subsequently .  As a consequence, there are now good reasons to suspect that Dual_EC_DRBG contains a NSA backdoor, and the NSA might be able to spy on anyone who is using Dual_EC_DRBG.  My questions:   Who uses Dual_EC_DRBG? Do any commercial products use Dual_EC_DRBG? Does anyone use it? Python dictionary: are keys() and values() always the same order? How does Linux handle multiple consecutive path separators (/home////username///file)? I'm working on a python script that passes file locations to an scp subprocess. That's all fine, but I'm in a situation where I may end up concatenating a path with a filename such that there's a double '/ in the path. I know that bash doesn't care if you have multiple file separators, but I'm wondering how exactly that is rectified. Is it bash that strips extra /s or does it really not matter ever?  I ask because it will save me several lines of code to check for extra /s while concatenating. I know it's not a big deal, but I'm curious as well. I have a bash script that has the line cd //usr (instead of cd /usr), which seems to imply there might be a significance to using multiple /s in a path Making a 3D map with shapefiles, lidar and aerial image data I want to try to make a simple 3D map for a small area (10 square miles) with some housing, some roads and some vegetation on it. My geodata is as follows:    shapes with houses/roads/vegetation.  LIDAR point cloud data over the area (can easily be built to a dem). georeferenced aerial image.   Any idea where to start to bundle these geodata together and make a neat looking 3D map?
