Are there any clones/alternatives for running a Stack Exchange style Q&A site? Why do we need multiple approvers for suggested edits? I already have the "Edit Questions And Answers" privilege. Yet, if I approve someone else's edit, I'm told that more votes will be required before the edit is accepted.  This seems a bit peculiar to me, since I could just copy the edited version and paste it myself. Make bibliography appear in toc as a chapter, not section Can you check if a PSN code is valid without redeeming it? I have a code for additional content on a Playstation game, and I want to know whether it is still valid, but I don't want to redeem it for myself.  If I enter it in the Playstation Store (on PS3, PS4 or the website), does it get redeemed to my account automatically, or can I enter it without redeeming? If it gets redeemed automatically, is there another way to check if it is valid? How to say that the phone is held between shoulder and ear? What are common phrases an English native speaker would use for the pose of speaking on the phone where you use your shoulder to keep the receiver against your ear (and mouth), so your hands are free?  I have some ideas, but they all sound wooden, and I don't think I've ever heard anyone describe this pose in words. It's also pretty much impossible to google for a pose or look it up on leo.org or other dictionaries.  OK, since people keep asking for what phrasings I found, I'll provide two, though I was hoping I could avoid influencing people who answer here by not providing them: "balance on one's shoulder", "held/nestled/sandwiched between shoulder and ear". Validate/verify PDF files integrity How to get vertex normals from a shape-key in Python? I'm trying to create an exporter for a format, which includes shape key support. This format requires both vertex coordinates and normals to be specified. This should be logical, because the vertex selected on the image below won't have the same normals:     Comparing it to this one:    But I actually haven't found any way to export shape key normals. Both Bmesh Vertex and ShapeKey Vertex only store the coordinates.  Is there any way to get them? Why is ScreenToWorldPoint always giving same coordinates with mouse position? Whenever I use ScreenToWorldPoint(Input.mousePosition) and display the output in console this always gives me the same coordinates. MyCode: Vector3 screenToWorld;  void Update() {     screenToWorld = Camera.main.ScreenToWorldPoint(Input.mousePosition);     Debug.Log(screenToWorld); } Website display problem - across all browsers whenever I go to  or  the page loads like this:    How can I fix this? Serana disappeared during dawnguard questline. Is it possible to automatically "add" \left and \right commands in front of all brackets? The source code should be left intact, but LaTeX should interpret every pair of brackets as if they were preceded by such commands. This is because adding \left and \right commands is time consuming and makes source code longer and less readable. I considered defining new commands such as \lb and \rb for \left( and \right), but it doesn't seem very elegant to me: what if I also want to add square brackets for example?  Any ideas? Thanks. Let $P\in\mathbb{R}[X]$ be a positive polynomial.  I want to show that there exists $A,B\in\mathbb{R}[X]$ so that $P=A^2+B^2$    $\displaystyle P=a\prod_{k=0}^q(x-a_k)\prod_{k=0}^{2p}(x-b_k)=a\prod_{k=0}^q(x-a_k)\prod_{k=0}^p(x^2-2\Re(b_k)+|b_k|^2)$ where $a$ is the leading coefficient, $a_k$ are the real rooks, $b_k$ are the complex roots.  What can i do now ? I know that the identity $(a^2+b^2)(c^2+d^2)=(ac-bd)^2+(ad+bc)^2$ should come in handy, but I can't figure out :  1) How to show that the product real roots is a square  2) How to use the above identity for the complex roots.  If I can solve those two points, then I can solve the problem. I have a HP-G62 B17S laptop, which has Windows 7 Home Edition 64-bit.  I read on a blog about a setting in msconfig.exe (Windows System Configuration utility):     Boot > Advanced options > Number of Processors   This was showing 1 for me but I have a dual core AMD Turion, so I changed the setting to 2. Next to it was a Maximum Memory setting (which was unchecked). I checked it and made sure it was max 4096; my system has 4GB RAM.  After restarting the laptop, it now gives an error:     Windows Error Recovery   Windows failed to start   I can choose from two options:   Launch Startup Repair Start Windows normally.   When I select Startup repair, it goes on to give another error:     Windows Boot Manager       Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:         Insert your Windows installation disc and restart your computer.    Choose your language settings, and then click "Next."     Click "repair your computer."      I do not have the Windows installation disc for this OS version - the manufacturer did not send it to me when I purchased the laptop.  If I try to start Windows normally it takes some time and then gives the same error message.  I tried inserting another installation disc of Windows 7 Professional Edition 64-bit (available from my other laptop), and restarting, but no repair menu comes up.  I also tried restarting the laptop, pressing F8 to enter Advanced Startup Options and selecting to boot with the Last known good configuration, or starting in safe mode - neither option gives any success. This time it gives a Blue Screen of Death with the following message:     A problem has been detected, and Windows has been shut down to prevent damage to your computer - BAD_SYSTEM_CONFIG_INFO   It then does a crash dump of the memory and restarts with the same options of repairing or starting Windows normally as earlier.   What exactly seems to be the problem here and its cause? What are my options now to restore/repair my Windows 7 OS to a working condition? Would the manufacturer send a recovery/repair disk for this if I called them? The laptop should be in warranty period - it was purchased six months ago. I have a Ubuntu 10.04 bootable CD. Is there any way to boot into Ubuntu, and repair Windows from there? Are there any other way to recover the OS? (I have an access to a working Windows Vista HP Laptop, if that helps)   EDIT Ok, it was able to boot through the Win-7 professional Installation disc, but even after doing Startup repair, and System restore, It still does not boot into the original Win-7.

Any help. In Italian, when I write a sentence about an action (e.g. eating fish, playing), I would use the infinitive, such as  mangiare pesce fa bene alla salute (which literally is "to eat fish is healthy"), or giocare aiuta ad imparare (which literally is "to play helps to learn").   I would use the gerund in giocando si impara, but that would roughly mean "When playing, you learn." and in this case the infinitive would not be correct. (Giocare si impara is not what you would say in Italian.)  Should I use the infinitive, or the gerund, in sentences similar to the following ones?   To play with fire is dangerous. To win the lottery is just a matter of luck. To escape from Alcatraz is impossible. To practice makes you perfect.   Is the infinitive always wrong, when the verb is the subject of a sentence? How do I run executable scripts in Nautilus? When I double-click on a script in Nautilus to run it, the script just opens in my text editor with no option to run it.

Prove: If $a\mid m$ and $b\mid m$ and $\gcd(a,b)=1$ then $ab\mid m$ I'm trying to figure out the name of a movie I saw on TV as a kid, in the mid-to-late 90s, in the US, in English, on daytime TV.  I remember it being kind of Starship Troopers-esque, but everyone had these glowing lights in their chests.  They glowed in different colored patterns, and I think it had something to do with whether you were attracted to someone or not (I was probably like 7 when I saw it, I didn't really understand the context of that part yet). I want to know if my server is running Subversion 1.5.  How can I find that out?  Also would be nice to know my SVN client version number. svn help hasn't been helpful.  Note: I don't want my project's revision number, etc. This question is about the Subversion software itself. How many actuations are "too many actuations"?
