I'm looking for a screen capture tool working on MacOSX that will export the capture to animated gif. Rotate whole animation by 90 degrees I make my animation and now I realized that its pointed in wrong direction I used -y (native blender) as direction but I need to be pointed at x axis so what would be the easiest way to rotate whole animation, to switch -y with x :) What does the colon in Tikz coordinates mean? How to cancel a jquery.load()? Where is the "Add vector layer"-button in GRASS 6.4.4. plug-in QGIS 2.10.1? I've just downloaded and installed the new version of QGIS 2.10.1 with GRASS 6.4.4.  When opening a new GRASS mapset and importing layers, I missed the button "Add a new vector layer". I've updated the GRASS plugin, but again the button wasn't there (all other GRASS symbols except "add raster layer" were visuable).  It's maybe a stupid question of a GIS beginner, but what can I Do? Is there an option to add (not import) a vector layer via the GRASS toolbox? Given 4 integers, $a, b, c, d > 0$, does $\frac{a}{b} < \frac{c}{d}$ imply $\frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}$? How can reincarnated souls be summoned using Edo Tensei? Quoting ,     Reincarnation is the philosophical or religious concept that an aspect of a living being starts a new life in a different physical body or form after each biological death. It is also called rebirth or transmigration, and is a part of the Saṃsāra doctrine of cyclic existence.   Then, since Ashura has reincarnated into Naruto, and Indra into Sasuke, how can Uchiha Madara and Senju Hashirama (their previous reincarnation) be summoned using Edo Tensei? As asked in the title? Does the independence of two random variables $X$ and $Y$ imply the independence of $X$ and $X+Y$? If so, what's the easiest way to prove that? What updates should be done to older monsters to bring them in line with MM3 era monsters? I know that to better balance paragon and epic level players against similar level monsters, WotC changed the math used for monsters for MM3, and I believe that they changed some of the types of powers they gave monsters.   If I want to update monsters from MM1 or MM2 to be in line with MM3 era monsters, what changes should I make? $\sum\limits_{n=1}^{\infty}\frac{1}{1+z^n}$, $|z|&gt;1$.  There are two facts that my professor uses that I am confused about.  The first is: $|1+z^n| \geq ||z|^n-1|$, I believe this is true for any $|z|$.  The other is: $\frac{1}{|z|^n-1} \leq \frac{2}{|z|^n}$, I believe this is also true for any $|z|$.  Can anyone prove these statements for me? I would like to show that  $$\forall n\in\mathbb{N}^*, \quad \sqrt{\frac{n}{n+1}}\notin  \mathbb{Q}$$  I'm interested in more ways of proofing this.  My method :  suppose that $\sqrt{\frac{n}{n+1}}\in  \mathbb{Q}$ then there exist $(p,q)\in\mathbb{Z}\times \mathbb{N}^*$ such that $\sqrt{\frac{n}{n+1}}=\frac{p}{q}$ thus   $$\dfrac{n}{n+1}=\dfrac{p^2}{q^2} \implies nq^2=(n+1)p^2 \implies n(q^2-p^2)=p^2$$ since $p\neq q\implies p^2\neq q^2$ then  $$n=\dfrac{p^2}{(q^2-p^2)}$$  since $n\in \mathbb{N}^*$ then $n\in  \mathbb{Q}$   I'm stuck here and I would like to see different ways to prove $\sqrt{\frac{n}{n+1}}\notin  \mathbb{Q}$ Can a Stack Exchange association bonus be lost? I recently hit 200 rep on Stack Overflow and got a big 100 rep bonus. Most know this as the 'association bonus'.  If I offer a bounty of 50 points and thereby lessen my 'base' score, do I lose that association bonus?  What if I offer a 150 point bounty and then work my way back to 200? Why $f(x) = \sqrt{x}$ is a function? Why $f(x) = \sqrt{x}$ is a function (as I found in my textbook) since for example the square root of $25$ has two different outputs ($-5,5$) and a function is defined as "A function from A to B is a rule of corre- spondence that assigns to each element in set A exactly one element in B.", so $f(x) = \sqrt{x}$ is not a function? Show that both mixed partial derivatives exist at the origin but are not equal $$f(x,y) = \begin{cases} \displaystyle \frac{xy(x^2-y^2)}{x^2+y^2} &amp; \text{if } (x,y) \neq (0,0), \\ 0 &amp; \text{if } (x,y) = (0,0). \end{cases}$$ I tried finding both mixed partial derivatives but they ended up being the same for that function. I must be failing to take into account something dealing with the fact that it is piece-wise. I still need to show the mixed partial derivatives exist. How can I do all of this? convert ceil to floor I have created 50 spreadsheets for 50 students. Each spreadsheet contains 33 sheets, numbered 1 to 33, along with a couple of other sheets.  Within each of these 33 sheets, there are many protected ranges.  I accidentally protected a range that ought not to have been protected. So, with 50 students each having 33 sheets, I have over 1800 sheets to unprotected.  I want to loop through each sheet, 1 to 33, and remove protection from cell F15. Right now, I (the owner) am the only editor.  Since I'm not an actual programmer, I've clearly not done this properly.  Can someone offer a suggestion of how I can change my Google Script to make this work?  var ss = SpreadsheetApp.getActiveSpreadsheet(); var sheets = ss.getSheets();  for (var i=2; i  &lt;sheets.length; i++) {   var sheet = ss.getSheets()[i];   sheet.activate();   SpreadsheetApp.flush();   var range = sheet.getRange('F15');        var protection = range.protect().setDescription('Protected range');        var me = Session.getEffectiveUser();        protection.addEditor(me);        protection.removeEditors(protection.getEditors());        if (protection.canDomainEdit()) {          protection.remove();          } //end of if statement  } Setting a custom RGB background color in beamer I believe I've correctly followed the manual in defining a custom background color in the example below.     But as the example shows, the background color is black rather than an extremely pale beige.

I would like to just provide a folder which contains data to install, and a script to be executed after installation.  Is this possible? What is the difference between a field and a property? New Zealand pronunciation of "women" vs "woman" I have read in a number of places that the NZ pronunciation of "women" must be rather peculiar. Quoting from :     For some years I've noted the tendency of Kiwis to pronounce "woman" and "women" identically (as "woman").   To which an Australian replies:     It appears there is a vowel shift going on in New Zealand (NZ) English [...] [T]he vowel in "women" which in Australian English is the same as the vowel in "hit", is often, in NZ, reduced to a schwa [...]. It makes the plural sound like our singular. I don't think the NZ pronunciation of the singular is the same as the NZ plural   A New Zealander begs to differ:     I've noticed this trend over the last few years also. To me as a kiwi it doesn't sound anything like a mispronounced plural -- it just sounds as if the speaker is using the one word for both singular and plural. [...] I see it as part of a much larger tendency to confuse singular and plurals. [Several examples follow.]   Who's right? Who's wrong? Wikipedia has :     In New Zealand English the short i of KIT is a central vowel not phonologically distinct from schwa /ə/, the vowel in unstressed "the". It thus contrasts sharply with the [i] vowel heard in Australia. Recent acoustic studies featuring both Australian and New Zealand voices show that the accents were more similar before the Second World War and that the KIT vowel has undergone rapid centralisation in New Zealand English. Because of this difference in pronunciation, some New Zealanders claim that Australians say "feesh and cheeps" for fish and chips while some Australians counter that New Zealanders say "fush and chups".   So, there appears to be a vowel shift going on; but I'm not sure if there might be some truth to the people-just-stop-caring-about-certain-plurals argument as well.  I hope we have enough New Zealanders on board to shed some light on this.   Can you provide a guide to how to pronounce "women" and "woman" in NZ English? (I've done some searching for audio files or YouTube videos, but haven't found anything yet.)  Would you say that it's just the vowel shift, "a much larger tendency to confuse singular and plurals", or both?  How recent is this trend? (E.g., if you are a native speaker of NZ English, is your pronunciation of "women" different from that of your parents/grandparents?)
