OS X Internet Recovery doesn't see SSD drive I wanted to do a clean install and booted from OS X recovery partition. In disk utility I selected "erase" option. SSD was working correctly before that.  Now, if i startup, the only way to proceed is with Internet Recovery  since I cannot boot from hidden recovery partition. After I wait several hours for the recovery image download, I cannot see the SSD either in disk utility or OSX reinstallation.   In terminal   diskutil list   Shows only recovery image 1.8 Gb or so.  So did erase option destroy my ssd? What level are spells cast at if a warlock multiclasses as another caster?

Big-O proof showing that t(n) is O(1) Let t(n) = $\sqrt{n^2+100n} - n$  Show that $t(n)$ is $O(1).$  I tried solving this using the formal definition of O( ) but am not getting anywhere. Quite confused on how to tackle this question. I know that the gravitational interaction of antimatter is expected to be the same as normal matter.  But my question is, has it ever been experimentally validated?  I think it would not be a trivial experiment, because electromagnetic effects have to be eliminated, so neutral particles would be needed. Maybe diamagnetically trapped antihidrogen atoms could be examined as to which direction they fall? I have tried using glm::rotate and such. glm::translate works fine, but rotate doesn't work (if I rotate before/after a translation).  Here is my current setup:  glm::vec4 Off = glm::vec4(0, 0, 0, 1); glm::vec4 result = Util::createTransform(offset) * Off;  for (int i = 0; i &lt; Tvertex.size(); i++) {     Tvertex[i] += glm::vec3(result.x, result.y, result.z);     Tcolors[i] = currentColor; }   And here is my Util::createTransform:  glm::mat4 Util::createTransform(glm::vec3 pos) {     glm::mat4 trans = glm::mat4(1.0);     trans = glm::translate(trans, pos);     return trans; }  glm::mat4 Util::createTransform(glm::vec3 pos, glm::vec3 rot) {     glm::mat4 trans = glm::mat4(1.0);     trans = glm::rotate(trans, glm::radians(rot.x), glm::vec3(1, 0, 0));     trans = glm::rotate(trans, glm::radians(rot.y), glm::vec3(0, 1, 0));     trans = glm::rotate(trans, glm::radians(rot.z), glm::vec3(0, 0, 1));     trans = glm::translate(trans, pos);     return trans; } How to allow certain html tags?

Improving how suggested edits are displayed in your activity history Issue 1: I find it a bit irritating that when I click the Improve button and further edit it, even if I mark it as helpful, only Community takes the credit for the approval. I know the topic itself will contain the link to the suggested edit, but my activity history only says that I made an edit, and not approved a suggested edit. The same holds true for marking one as unhelpful. The activity history should say I rejected an edit, and then made an additional edit. I know it's not often, but sometimes I do try to go back to a suggested edit I've rejected, but when I improved and rejected, it's not traceable for me as it doesn't show in my history or in the question's revision history. So if I don't remember what user suggested it, it's lost to me.  This issue also plagues the  which are awarded for approving and rejecting suggested edits, which essentially you have done, you're just not receiving credit for it. I suggest that when I mark an edit as helpful or not helpful, both me and Community be listed as the approvers or rejecters, unless another user is already listed in the appropriate place.  Update: Here is  of the confusion this causes.  Update 2: Also, when improving a post and marking it as "not helpful", it would be nice to be able to  along with it.    Issue 2: Expanding off the idea that users need more notice for suggested edits that get rejected, the activity history page is much too useless when it comes to listing the suggested edits a user has made. Literally all it does is list them. A user still has to click through to each one in order to find out if it was approved or rejected, or even if it's still pending. Take, for example, this screen shot of the suggested edit history:    Is it really necessary to say I suggested a suggested edit? Really? Of course I suggested it, it's a suggested edit. This isn't !  A good way to fix this would be to change the second "suggested" word into one of: pending, approved, or rejected. This would be a quick way to tell which edits have been approved or rejected and which ones are still pending. Users would be able to target out rejected edits and review them for the reasons. Something like this: Statement: There are uncountably many surjections from $\mathbb N$ to $\mathbb N$.  Is the following proof valid:  The real numbers are uncountable.   There exists a bijection between the set of real numbers and the set of all functions from $\mathbb N$ to $\{0,1\}$.   Given a function, $f$, from $\mathbb N$ to $\{0,1\}$, construct a surjection from $\mathbb N$ to $\mathbb N$, denoted $g$, as follows:  We map the $n$th composite number to $n$, and the nth prime, to $f(n)$.   Clearly this is a surjection since the composite numbers are countable. Clearly different functions $f$ lead to different surjections $g$. Since there are uncountably many $f$s, there are uncountably many surjections $g$. I know that the Naruto movies are outside the timeline in the sense that they don't affect whatever happens after them. However, they must fall somewhere in the Naruto timeline — based on who are in the movies and how the characters look like, etc. For example, if Sasuke isn't in the movie, it should take place after he left. For each of the movies, approximately what timeframe (between episodes/arcs) are they set?  The movies:   Ninja Clash in the Land of Snow Legend of the Stone of Gelel Guardians of the Crescent Moon Kingdom Naruto Shippuden the Movie Bonds The Will of Fire The Lost Tower Blood Prison Road to Ninja The Last - Naruto the Movie Boruto: Naruto The Movie Why do function pointers all have the same value? Explain why $E(X) = \int_0^\infty (1-F_X (t)) \, dt$ for every nonnegative random variable $X$ Let $X$ be a non-negative random variable and $F_{X}$ the corresponding CDF. Show,   $$E(X) = \int_0^\infty (1-F_X (t)) \, dt$$   when $X$ has : a) a discrete distribution, b) a continuous distribution.   I assumed that for the case of a continuous distribution, since $F_X (t) = \mathbb{P}(X\leq t)$, then $1-F_X (t) = 1- \mathbb{P}(X\leq t) = \mathbb{P}(X&gt;  t)$. Although how useful integrating that is, I really have no idea. Pumpkin Noodles is a thing or are a thing? Which of the following is correct?

Open more than one instance of Windows 10 settings How can I open more than one instance of the Windows settings?

Example of the new settings window: String vs. StringBuilder I understand the difference between String and StringBuilder (StringBuilder being mutable) but is there a large performance difference between the two?   The program I’m working on has a lot of case driven string appends (500+). Is using StringBuilder a better choice? Present Perfect or simple past? Correlation between a nominal (IV) and a continuous (DV) variable I have a nominal variable (different topics of conversation, coded as topic0=0 etc) and a number of scale variables (DV) such as the length of a conversation.   How can I derive correlations between the nominal and scale variables? I'm a little confused about the following sentences. Could you please tell me which one(s) is/are correct?
