I am a new user and I just installed Blender 2.76b on a Lenovo R500, OS Windows XP Pro. I intend to use it mostly for (short) video editing. I could load, hear audio, cut and animate video correctly, but the preview is in a white square on a black background.   When I initialize Blender, I got the following output:  "AL lib: &lt;EE&gt; ALCdsoundPLayback_reset: Unknown system speaker config:0x0 Warning! Using result of ChoosePixelFormat."   and at the start this alert:  "Your system does not use 3D hardware acceleration. Such system can cause stability problems in Blender and they are unsupported. This may cause by: * A missing or faulty graphics driver installation.   Blender needs a graphic card driver to work correctly. * Accessing Blender through a remote connession * Using Blender through a virtual machine"   Cases two and three are not mine. Do I need any special driver for my graphics card (ATI Mobility Radeaon HD 3400 Series) to use Blender? Does it have anything to do with seeing no preview?
I add video files to the video editor,  Both audio and video channels appear but only the audio plays.  The video is just a white box.  Anyone know what is wrong.  Added video in WMV.  Also tried MP4 same thing.
It is perhaps a bit embarrassing that while doing higher-level math, I have forgot some more fundamental concepts. I would like to ask whether the square root of a number includes both the positive and the negative square roots.  I know that for an equation $x^2 = 9$, the solution is $x = \pm 3$. But if simply given $\sqrt{9}$, does one assume that to mean only the positive root? And when simply talking about the square root of a number in general, would one be referring to both roots or just the positive one, when neither is specified? How do I extract text that lies between parentheses (round brackets)? Why can't I press the Install button when installing applications from unknown sources? I'm trying to sideload an application, as seen in the picture below.    I have allowed the installation of applications from unknown applied actions in settings, but I can't seem to press the install button. The cancel button works correctly and installing applications via adb install works correctly. What's the problem?  EDIT: For those who have this problem, using ChainFire's  will correct it because the app uses hardware compositing, and Android doesn't notice a "layer" on top of the current screen. Use Cauchy-Schwarz inequality to show series convergence Describe the units in $\mathbb{Z}[\sqrt{-d}]$ I opened Cairo-dock in my terminal with: open cairo-dock and that worked but if I close the terminal it goes with it. How can I keep it open regardless of the terminal? do not optimize/remove html I would like to have a page with some html content in it that CK Editor does not seem to support, in particular: I want to have a little &lt;form tag with a couple of &lt;input fields. I can enter it in Switch to plain text editor mode and save from there and it will keep the elements but when I want to edit the page, it'll go back to the Switch to rich text editor and remove my &lt;form html items. How can i set CD Editor to not remove any html it may not be able to render?  Thank you! Infinitely differentiable function with given zero set? Would you capitalize the job title in the following sentence?      I am writing this letter in regard to Joe Brown who is applying for the director of teaching and learning position in the XYZ School District. Continuity of $\sin(x)/x$ Is $\sin(x)/x$ continuous at $x=0$,(perfectly, not tends to)? The function has right hand and left hand limit same and equals 1 but what happens at perfect zero?it should be undefined. Is it?

Why there isn't a feature that lets any user on SO to request other user to answer their question? When I browse through other questions to find my answer, sometimes I'll find answers similar to what I'm looking for, and though they don't exactly answer my question, the author might be able to do so. Could we have a feature on SO that will let me request that another user answer my question, in case I find someone who could potentially answer my question? The coefficient of $x^9$ in the expansion of $(1+x)(1+x^2)(1+x^3)...(1+x^{100})$.  I tried the following concept, how to sum 9 using 1-9 only without repetition.  1:9, 2:1+8,3:7+2, 4: 6+3, 5: 5+4,  6:1+2+6 ,7:1+3+5, 8:2+3+4  The answer is 8.  How will it be solved using Binomial theorem. How do I set up a "secure" open resolver? This is a  about securing public DNS resolvers   Open DNS servers seem pretty neat and convenient, as they provide IP addresses that we can use consistently across our company regardless of where they are located. Google and OpenDNS provide this functionality, but I'm not sure that I want these companies to have access to our DNS queries.  I want to set up something like this for use by our company, but I hear a lot about this being dangerous practice (particularly in regards to ) and I want to make sure that we do this right. What things do I need to keep in mind when building this type of environment? Can it hurt to put my GRE score on my resume? If my score is good and if I'm applying for an MS program in Europe, can it give me any kind of edge? The university I'm applying to requires GRE scores for certain programs but not the one I'm applying for. And if it won't be advantageous, can it hurt my prospects in anyway? getting exception while putting list data into the map How to add appendix in thesis using LyX I want to add an appendix (questionnaire etc.) at the end of my thesis after the references.

Alice and Bob have a child, Erin. Bob and Carol have a child, Frank. Carol and Dan have a child, Grace. Clearly, Erin and Frank are half-siblings, because of their father, Bob. Similarly, Grace and Frank share their mother, Carol.  Erin and Grace have no parents in common, and are thus not half-siblings. However, is there a term for their relation?
